PORTABLE HUMIDIFIER Filed Nov. 29, 1963 5 Sheets-Sheet 1' Z2 Z5 Z3 Z2 IN VENTORS.
United States Patent O I This invention relates to apparatus for disbursing water into the ambient air and, more particularly, to improvements in household portable room humidifiers of. the
mechanical type which. generate a great profusion of minute water droplets.
The present invention is assigned to the same assignee as the Bradley Patent No. 3,005,591 disclosing a mechanical humidifier which has been manufactured and sold by the assignee throughout this country. Humidifiers man ufactured following the teachings of the Bradley patent have enjoyed considerable commercial success due to their ability to introduce a considerable volume of water into a room without materially influencing the amblient temperature therein. The Bradley humidifier could be used in the bedroom of a user experiencing a respiratory disease without subjecting the patient to an increased air temperature which might be detrimental to health especially during the evening hours. In addition, the portable humidifier may be used in any room within the house. One problem encountered with the mechanical humidifier which injects water droplets upwardly into a household room is that large water droplets egressing therefrom would fall before evaporation had occurred. Further, water droplets which were small enough to be sustained by the rising air column would collide with other mediumsized droplets to form large droplets which would again fall before evaporating. Still another problem is that large water droplets would form' within the humidifier housing near the exhaust port and the rush of forced air egressing therefrom would lift the large water droplets out of the housing which would'subsequently fall onto the top wall of the housing giving the impression that the housing was sweating. Thus, there is. a need for an improved humidifier which would economically control the size of the water particles egressing. from the exhaust port in order to overcome the disadvantages of the prior art humidifiers.
It is, therefore, an object of the present invention to provide an improved humidifier which atomizes and introduces into the ambient air a profusion of minute water droplets which can readily be evaporated before falling.
Another object of the present invention is to provide an improved humidifier which will prevent large droplets of water formed within the housing from being carried by forced air through the discharge port.
Still a further object of the present invention is to provide a humidifier having an improved seal between the vessel and the cover to prevent the egression of minute Water droplets therebetween.
Yet another object of the present invention is to provide a humidifier having an improved pump for discharging a substantially constant volume of water regardless of the level of the Water within the humidifier vessel.
Still another object of. the present invention is to provide an improved humidifier having a passageway therein to remove large water droplets from the moisture-laden air egressing therethrough.
With the above and other objects in view which will appear as the description proceeds, this invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of 3,290,021 Patented Dec. 6,19
the hereindisclosed invention may be madeas come within the scope of the claims. 1

Referring now to the drawings, there is illustrated an electrically driven appartus for dispersing minute droplets of water into the ambient air indicated by the reference numeral 10 which is commonly designated as a portable room humidifier. The humidifier 10 comprises a housing 11 having a cup-shaped cover 12 which is adapted to cooperate with a bottom member or vessel 13 to form an enclosure or chamber 15 in which minute'water droplets or water spray is generated. Preferably, the bottom member 13 has a substantially cup-shaped configuration with upstanding walls 14 and a bottom wall 16. In the embodiment illustrated, both the cover and vessel are of molded plastic construction. As seen in FIG. 2, the vessel 13 has a sight gauge 17 to indicate the water level therein, disposed along the wall 14. Recessed handle portions 18 are formed in the upstanding wall 14 to facilitate the transportation of the humidifier. rigidity to the wall 14, a plurality of horizontally extending, vertically spaced strengthening grooves 19 are formed thereon. A plurality of supporting feet 22 are provided on the bottom wall 16 which feet are preferably circular rubber pads to lessen the vibrations transmitted to the supporting surface. Integrally formed on the bottom wall 16 are radially extending raised ribs 23 which are centrallypositioned for reducing the movement or circulation of the water contained within the vessel 13 due to the rotation of a conical pump to be described hereinafter. According to the present invention, a water seal 26 is disposed between the cover 12 and the vessel 13 in order to prevent the egression of minute water droplets therebetween. The cup-shaped cover 12' includes a depending skirt 27 having a slightly outwardly angled portion 28 which merges into a substantially vertical wall portion 29 near the periphery thereof. In the present embodiment, the vertical portion 29 ofthe skirt is approximately fiveeighths of an inch high. A notch 30-is formed in the vertical portion of the skirt to provide'clear'ance for the sight gauge 17. The'vertical portion 29 of the skirt terminates at a peripheral edge 31. Disposed along the top of the upright wall 14 of the vessel 13 is a peripheral flange or inwardly facing channel 33 having a somewhat'U-shaped cross section comprising a lower, somewhat horizontal leg 34, a bight portion 35 and an upper, somewhat horizontal leg 36 which terminates inwardly at an edge 37. As can readily be seen in FIGS. 2 and 8', the cover 12 is supported on the vessel 13 by the edge 31 of the cover skirt resting on the lower leg 34, and this line of contact between the cover and vessel forms and defines a first water seal or barrier. In this assembled position, the
In order to afford edge 37 engages along the vertical portion 29 of the cover 'der pressure will be prevented from passing between the In addition cover and vessel by the aforesaid two seals. to the tightness of the fit present'in both seals, it can be readily seen that water spray which is able to pass the first seal will collect between the two seals and flow back adjacent the outside of the first seal to form a water seal or dam. Preferably, the second water seal is disposed substantially above the first seal as illustrated in FIG. 8 in order to facilitate the establishment of a water darn outside of the first seal.
The cover 12 has a top wall 41 with a depending motor wall 42 which is U-sha-ped as viewed in plan in FIG. 3 and which joins the cover skirt 27 at one side. The molded cover 12 defines an integral grill opening or air entrance 43 disposed between the legs of the depending wall 42. A horizontally disposed dividing wall 44 abuts the bottom of the depending wall 42 and cover skirt to define a motor chamber 46. The grill opening 43 provides an air access to the motor chamber 46. Disposed Within the motor chamber 46 is a conventional shaded pole motor 45 which in this particular embodiment is designed to operate at 2,800 rpm. under load. As may be seen in FIGS. 2 and 5, an integrally molded groove 47 is disposed along the top surface of the dividing wall44 and is adapted to receive the depending wall 42 therein to insure that no moisture may pass into the motor chamber 46 between the wall 42 and the dividing wall. The dividing wall 44 has a slightly inclined portion 48 which terminates at a circular air inlet opening 49 for the chamber 15. The motor 45 is fastened to the dividing wall 44 by a plurality of threaded fasteners 50 which are insulated from the motor by rubber dampening members 51. The dividing wall 44 is securely fastened in position by a plurality of threaded members 52 which engage mounting lugs 53 on the depending wall 42. Extending downwardly from the motor 45 is a drive shaft 60 which passes through the opening 49 into the chamber 15.
As shown in FIG. 5, a pump assembly 61 for dispensing a profusion of water droplets is secured to the motor drive shaft 60 by a threaded member 62. The pump assembly comprises a conical member 63 which engages at its upper end to a downwardly dished or concave slinger member 64 and a slinger disc 65 which is horizontally disposed therebetween. Preferably, conical member 63 and slinger member 64 are molded from plastic, such as polystyrene. The conical member 63 which is coaxial with the vertical motor shaft has an inside or interior surface 66 which is inclined outwardly and upwardly in order to feed water toward its upper end upon rotation thereof due to centrifugal force in a manner well known in the art. The rate of water delivery by centrifugal conical pumps varies with the water level in the vessel because of the difference in the hydraulic head and the inside surface of the conical member exposed at the water level. One of the salient features of the present invention is a conical pump which will deliver water at a substantially uniform rate regardless of the changes in the liquid level contained within the reservoir or vessel 13. In order to obtain uniform water delivery, the lower portion of the conical member 63 has integrally formed on the interior surface 66 a pair of oppositely disposed spiral ledges 68 of tapered thickness having a thin leading edge 69. Eachspiral-ledge 68 is inclined upwardly around the interior surface for approximately 180 degrees so that the leading edge 69 may effectively scoop water upwardly along the spiral ledge. The bottom surfaces 70 of the conical member63 are inclined upwardly from r V the leading edge 69 to a point above the other leading edge. With this construction, which may be seen in face 66.
FIGS. 5 and 7, the leading edges 69 are exposed and may readily bite into the' Water" which tends 'to' establish a'constant condition on the inside of the conical member regardless of the water level to produce a constant water delivery upwardly along the interior surface.
Near the top of the conical member 63 are a plurality of integrally formed interior ribs 71 extending radially from the inside surface 66. The slinger 64 has a central hub portion 73 to receive the drive shaft 60 and a plurality of ribs 72 extend radially from the hub to be juxtaposed with the interior ribs 71. The outer edges of the ribs 72 are longitudinally inclined to mate with the interior sur- In order for the conical member 63 to be attached rigidly to slinger 64, a water resistant adhesive or solvent is preferably used to lock the outer edges of ribs 72 with the interior surface 66. With this arrangement, the slinger ribs 72 perform the combined function of positioning the conical member 63 to assure proper alignment along the drive shaft axis and also provide a solid support for transmitting rotary motion to the conical member 63. Disposed along the top of the conical member 63 is an annular flange 75 having a plurality of laterally extending support lugs 76 spaced from the top of the flange 75 and vertically extending spacing lugs or upstanding projections 77 which are adapted to contact the bottom surface of the slinger 64 in order to space the flange sufficiently therefrom to define a water passageway or orifice. It can be easily seen that water passing upwardly along the inclined interior surface 66 will pass over the flange 75 to be thrown outwardly by centrifugal force.
Even though the slinger 64 is dished downwardly slightly and the flange 75 is positioned closely adjacent to the bottom of the slinger, the water passing over the flange 75 will not uniformly spread outwardly along the slinger to the periphery thereof. It is well known that water traveling in a spiral path along the underside of the centrifugal slinger will track along a few paths which have become wetted. Under stroboscopic examination it can be seen that a plain slinger will function in the same manner as if only two or three conduits were spirally disposed. In a mechanical humidifier, it is necessary to have the water uniformly dispersed from the periphery of the slinger in order to minimize the size of the water droplets being flung outwardly. The present invention accomplishes uniform water distribution along the slinger periphery by positioning a resilient slinger disc 65 between the conical member 61 and the slinger 64. As may easily be seen in FIGS. 2, 5 and 6, the relatively thin doughnut-shaped slinger disc 65 has an outside diameter or outer edge 80 which is smaller than the outside diameter of the slinger 64 and has an inside diameter or inner edge 81 which is slightly larger than the diameter of the flange 75. To conveniently assemble the slinger disc 65 between the conical member 63 and the slinger 64, a plurality of spaced notches 82 are formed along the inside diameter 81 and spaced to correspond with the lateral flange lugs 76 in order that the slinger 65 may pass over the lateral lugs and subsequently be rotated so that the disc may be locked in a bayonet engagement. Thus, the disc 65 is supported on lugs 76 and radially located by flange 75 whereby the outside diameter 80 is in firm contact with the bottom of the slinger 64. Inasmuch as the slinger disc 65 is fabricated from resilient material, the peripheral line of contact between the slinger disc and the slinger is under relatively uniform tension. It will be appreciated that water forced upwardly through the conical member 63 will flow over the fiange 75 into the space between the slinger and the slinger disc and will be fed by centrifugal force to the peripheral line of contact. In this manner, water is uniformly fed between the disc 65 and the bottom of the slinger 64 at the line of contact so that the water fed to the periphery of the slinger will be uniformly dispersed therealong to produce minute droplets of water.
Preferably, a centrifugal fan 84 comprising a plurality of radially disposed fan blades 85 is integrally molded on the top of the slinger 64. In the present embodiment, the radial fan blades 85 have a generally rectangular configuration in the longitudinal plane and are inclined inwardly and upwardly toward the axis of the fan to conform with the inclination of slinger 64. The fan blades 85 are disposed below the opening 49 and are positioned closely adjacent to the dividing wall raised portion 48. The fan 84 is of greater diameter than the circular opening 49. Therefore, when the slinger 64 is rotated, the fan 84 creates a low pressure at the opening 49 which induces a flow of dry air through the entrance 43 into the motor chamber 46 and subsequently into the chamber where the pump assembly 61 throws water particles against a plurality of fingers 86 depending from the dividing wall 44 to further break up and reduce the size of the water droplets.
In order to prevent the water droplets which are deposited on the bottom of the dividing wall 44 from flowing toward the opening 49 due to the low pressure maintained there, an annular drip barrier 90 depending from the dividing wall 44 is positioned around opening 49. The lower edge of barrier 90 depends from wall 44 to a position between the top and bottom of fan blades 85 at the outside diameter thereof. The annular drip barrier or wall 90 has a general V-shaped cross section with a sharp apex to prevent the water formed along the bottom of the dividing wall 46 from passing thereover and flowing toward the opening 49 where drops of water may fall on the rapidly rotating fan blades to cause objectionable noise. Thus, the barrier 90 has a greater diameter than the opening 49 and the fan 84 but is of a lesser diameter than the slinger 64. With this arrangement, the drip barrier 90 effectively prevents water deposited on the underside of the dividing wall 44 from dropping on th fan blades 85.
As described hereinbefore, relatively dry air passes through the entrance 43 to the motor chamber 46 and into the main chamber 15 due to the rotation of fan 84. This air flow provides a dry motor chamber to afford troublefree operation of the electrical motor 45 Prior art humidifiers normally have the fan and the pump assembly combined in such a manner that both members must rotate at the same speed. Therefore, increasing or decreasing the motor speed will not substantially affect the fineness of the droplets produced by the humidifier. That is to say, as the motor speed is increased, more air is forced by the fan to pass over the slinger but the pump is also transporting more water to the slinger with the end result that water droplet size remains relatively constant. It is, therefore,-advantageous to have a mannually operated control to regulate the flow of air through the humidifier while the pump speed and delivery are constant to regulate the size of the water droplet. In order to provide the humidifier 10 with an air flow control, a pivotally mounted baffie 92 is positioned inside motor chamber 46 adjacent the entrance 43. The baffle member 92 is preferably molded of plastic and has a notch 93 along the bottom edge to provide access for an electrical cord 94 which passes through opening 95 in cover skirt wall 27 into the motor chamber 46 for connection with the motor 45. As may be seen in FIG. 2, the dividing wall 44 has an integrally formed upstanding finger 96 disposed behind the skirt opening 95 adapted to contact the power cord 94 to provide a strain relief therefor. The entrance 43 comprises a plurality of spaced vertical bars 105 integrally molded in cover skirt 27'. Two oppositely disposed hinge pins 100 are integrally formed along the bottom edge of the baffle 92 and are adapted to cooperate with notches 101 positioned at the bottom of inwardly extending rib members 102. Extending perpendicularly from bafiie 92 is an integrally formed curved arm 103 which is positioned to extend through the vertically spaced bars 105. Disposed along the arm 103 is a generally sphirical enlargement 104 which has a slightly larger width than the space between the bars 105 positioned on each side thereof to lock the baffle in the closed position as shown in FIG. 2. When a lifting motion is imparted on the end of arm 103, the baffle 92 is rotated inwardly snapping free of the engagement between the enlargement 104 and the bars 105 to vary the effective entrance opening. As seen in FIG. 4, when the baffle 92 is locked in closed vertical position, only two spaces between spaced bars 105 are uncovered, plus a small area around the cord opening 95 in notch 93. With the baffle in the closed position, less air passes through the humidifier and consequently smaller sized water droplets are propelled into the ambient air. Since the smaller sized water droplets egress from the humidifier with the baffle closed, a. longer time is required to discharge a given volume of water.
When the pump assembly 61 and the fan 84 rotate in chamber 15 with water in the vessel 14, there will be produced as hereinbefore described a profusion of minute water particles under pressure. Integrally formed with the cover top wall 41 is a raised discharge conduit 109 which treminates at discharge opening 110. Before the moisture-laden air generated in chamber 15 can egress through discharge opening 110, it must pass through a horizontally curved conduit 111 having a generally U-shaped cross section which forms a curved passageway 112 between the chamber 15 and the discharge opening 110. The conduit 111 is fastened to the underside of the cover top wall 41 by means of a plurality of small lugs 113 depending from wall 41 which are received in openings in conduit ears 11.4 which are integrally formed with conduit 111. Standard spring clips 115 lock onto lug 113 to firmly maintain the conduit in position. Preferably conduit 111 comprises sloping inwardly vertical walls 116 and 119 which merge into a bottom wall or bight portion 117 which is sloped downwardly towards inlet opening 118. It should be noted in FIG. 3 that the slinger 64 and fan 84 tend to rotate the moisture-laden air in a clockwise direction, and that opening 118 in conduit 111 faces the direction of air movement in order to receive the air in passageway 112. The bottom wall 117 of the conduit 111 is sloped downwardly both towards the opening 118 and the outside conduit wall 119 so that water deposited on the conduit flows along the bottom adjacent to wall 119 to be returned to vessel 13. The top of the conduit 111 is closed by cover top wall 41. The other end of conduit 111 has an opening 120 into chamber 15 which is closely positioned to discharge opening 110. Referring to FIGS. 2 and 3, it can readily be seen that the moisture-laden air entering opening 118 must traverse a horizontally disposed curved path defined by the curved conduit 111 and then a vertically disposed curved path defined by the discharge opening 110 being positioned over said conduit before emerging from discharge 110. As a consequence of the horizontal and vertical curves in passageway 112, the heavy larger water droplets carried by the rapidly moving turbulent air impinge upon the sloping walls 116 and 119 and are subsequently fed back into chamber 15 along the sloping bottom 117 adjacent the wall 119. It is readily understood that since the moisture-laden air in chamber 15 is rotating clockwise when viewed in FIG. 3, it tends to fiow adjacent wall 119 while in passageway 112. It is further understood that the pressure in chamber 15 will force a certain amount of air from the chamber through opening 120 into passageway 112 and said air tends to enter along and move adjacent to wall 116. Consequently, the air traveling clockwise along the inside of wall 119 from opening 118 and the air traveling counterclockwise along the inside of wall 116 from opening 120 as indicated by the arrows in FIG. 3 produce violent turbulence and swirling when brought together immediately below. discharge opening 110 which further precipitates the larger water droplets from the air stream before being discharged fromthe humidifier.-
For the purpose of further removing large water droplets from the stream of air channeled through passageway 112, an integrally molded drip barrier 125 depending from the top cover wall 41 is positioned around a portion of the raised discharge conduit 109. As may be best viewed in FIGS. 2 and 3, the drip barrier 125 extends from near the conduit wall 116 in an annular path to a position adjacent the end of wall 119 near opening 120. The drip barrier 125 has a lower edge 126 which slopes downwardly from wall 116 to wall 119. Therefore, the drip barrier 125 performs the dual function of causing the moisture-laden air to dip abruptly downward immediately prior to the vertically curved portion of passageway 112 and also feeding moisture deposited on the barrier to wall 119 for transmission back to the vessel. Thus large droplets are not permitted to hang adjacent to the discharge opening 110 .and be carried upwardly through discharge opening 110 by the air stream. With the embodiment illustrated in the drawings, the droplet size is sufiiciently controlled to eliminate both large droplets which are not capable of evaporating prior to falling and also medium-sized droplets which might unite to form larger droplets which again cannot evaporate prior to falling. Further, the present invention provides a humidifier which will expeditiously carry the water precipitated along the passageway 112 and the area adjacent the discharge conduit 109 back to the vessel without permitting the moisture to be carried upwardly in the air stream through the discharge opening 110. Thus, this invention has disclosed a humidifier which carefully directs a stream of minute water droplets upwardly without noticeable variations in capacity due to water level within the humidifier and which accurately controls the size of the minute water droplets. Further, the readily removable cover 12 forms a double seal with the vessel to prevent the escape of water droplets therebetween.
While there has been illustrated and described a particular embodiment of the present invention, it will be understood that charges and modifications may occur to those skilled in the art and it is, therefore, contemplated by the appended claims to cover all such changes and modifications as fall within the true spirit and scope of the present invention.

Thanks for the offer, but I typically don't trade for guys that are currently playing less than 20 mins a game. lol.
I have at least 5 guards averaging 6 assists or better these days. I'd love to trade for an impactful big. If you could use some good point guard...
Yeah, that hurt.
At 30-49, looks like you could use some. lol.
Thanks. Every now and then I get lucky.
You are dangerous from any position. Your safest position for the rest of us GMs is outside of the playoffs. lol.
Good matchup. I thought I had that one. I can't seem to get over the hump this year with my team. I'm going to have to do some analysis this week.

Historical Traveler Reviews Alif Hotel Lisbon
Das Hotel ist wirklich sch�n. Der Service ist komfortabel und zum Fr�hst�ck gibt es reichlich Auswahl. In manchen F�llen h�tte es sogar 4 Sterne verdient. Es liegt ca. 2-3 Minuten von der n�chsten Metrostation entfernt.
Schönes Hotel in einer guten Lage
Waren f�r drei N�chte im Alif Hotel und fanden es sauber und komfortabel. Sehr gute Lage in der N�he der Metro, mittel derer man gut innerhalb von Lissabon herumkommt. Es war wirklich angemessen. Leider war der Ausblick aus unserem Zimmer einfach h�sslich, da es nach hinten hinaus lag.
Nice hotel in good location.
stayed for three nights in Alif Hotel,found it clean and comfortable.very good location near metro which is a great way to travel around Lisbon.It was very reasonable.Our only complaint was the view from our room was awful as it was at the back of the hotel.
Above average
Hotel is in a very nice place. Services is comfortable, breakfest is plentiful. It could be 4 stars in some cases. It is 2-3 minutes from metro station.
Perfectly reasonable
i got the Alif from a list for people attending conferences. my room was pretty cheap at 60 euros a night. i was pleased with the location, a bit out of the centre of town, on an underground line, with very easy access to the airport (the aerobus stops at Campo Pequeno) and to the city. the hotel looked a bit shabby from the outside, but inside it was fine - my room was clean and well maintained. i hardly use hotel bars but i got cold sparkling water there and the bar area itself was very pleasant. the restaurant is on the 9th floor with good views particularly over the architecturaly interesting old bull-ring, now being redeveolped into shops / cafes / offices. if you want a vegetarian restaurant, you must go to Terra in Barrio Alto - excellent.

The present invention relates to a device for training a sequence of movements for ball-hitting implements, especially golf clubs or baseball bats.
In sports in which ball-hitting implements are used, for example golf, generally a complex sequence of movements will be encountered in using these implements. Learning, practicing and monitoring these sequences of movements poses problems for beginners. By incorrect execution of the corresponding movements and inadequate correction of these errors, rapid progress and the associated sense of achievement remain elusive for beginners. Even in players who play these sports professionally, the pertinent monitoring of sequences of movements is regarded as an indispensable prerequisite for good play.
In the past, for checking the sequence of his movements, a player had to enlist another individual to watch and correct him, or to use complex video technology allowing him to examine the execution of his movements subsequently. These measures, whether time with a coach or use of video cameras, is expensive for the player and, if at all, is not always available to him at the desired time. It is furthermore disadvantageous, that when subsequently viewing the recorded video material, the respective player does not have the opportunity to directly correct errors in the sequence of his movements and in particular he does not receive any feedback (biofeedback) about his errors.
U.S. Pat. No. 5,150,901 discloses a golf training device which can be fixed to the upper body of the user by a chest harness. The device itself has two telescoping sleeve parts which are held to be able to travel lengthwise into one another. One telescoping part engages the chest harness. The other telescoping part engages the grip of the golf club. As a result of the rigid arrangement of these telescoping parts which can travel lengthwise into one another and as a result of fixing the training device by the indicated chest harness, the golf-playing user is also greatly hampered in his play during training so that the approach is less feasible for practical applications.
U.S. Pat. Nos. 3,861,688 and 5,108,103 disclose golf training devices with acoustic feedback. The training device is attached especially to the wrist of the golfer and to the golf club itself in the vicinity of the grip. An elastic resettable connecting part between the wrist and the golf club monitors the centrifugal force situation during the sequence of movements. When the sequence is not ideal, the golfer receives a corresponding error or correction report via an acoustic signal. Since with these devices essentially only correct monitoring of the hand position during the course of the stroke, mispositioning of other body parts, especially with regard to arm posture during the golf stroke, remains ignored. Accordingly, these known devices do not ensure that the entire sequence of movements during the golf swing is practiced correctly to master the entire sequence of movements in this way.
GB-A-988 796 and GB-A-2 336 787 disclose establishing a connection between a golf glove or the club grip and the shoulder or the upper arm of a golfer of bands and loops. The bands and loops are designed to capture the centrifugal forces during the swing and deliver feedback about the correct sequence of movements to the user. In the golf training device of GB-A-2 336 787, only one-hand training motion is possible, with the other hand being kept stationary by the user on the upper body. The training device touches the shoulder of GB-A-988 796. By a resettable force means, another band is placed under the opposite shoulder of the other arm of the user. During the stroke motion, the shoulder band cannot unintentionally slip down. With the known training device, the user can carry a golf bag or the like supported by the shoulders of the user. In particular, this mitigates tiresome carrying on longer golf courses. The training effect with these known devices is likewise rather small. If only one hand or one arm is correctly trained for a sequence of movements, this training does not apply to the sequence of movements with the two stroking hands of a user, as experience indicates.
U.S. Pat. No. 3,339,926 discloses a golf training device which engages between the wrist and the upper arm of the user. Fixing possibilities in this regard are closing bands between which extend two telescoping sleeve parts. The parts fit into one another with a lengthwise travel capacity on their facing ends. The telescoping part facing the wrist has a slotted guide. The other telescoping part on its outside periphery has a fixing aid with a movable chain. This arrangement permits monitoring the bending motion of the arms during the stroke such that overbending cannot occur. An unintentional motion is intercepted by the chain of one telescoping part which then fits into the slotted part of the other telescoping part in an obstructing manner. A certain pattern of movement can only be partially monitored, specifically any overbending of the arm posture during the sequence of movements so that the entire sequence of movements during a golf swing cannot be properly monitored and trained in this way.
Objects of the present invention are to provide a player with a simple and economical aid for directly noting and correcting errors in the sequence of his movements when hitting the ball, without being reliant on the assistance of third parties or on complex video recording technology.
The foregoing objects are basically obtained by monitoring means having at least two component parts detachable from one another and interactable with one another by a force means. In this manner, at least at the start and end of the sequence of movements, the detachment of the component parts is obstructed or their joining takes place in an accelerated manner. The force means opposes the centrifugal force during the swinging motion with the ball-hitting implement. Both the detachment of the component parts and the later joining deliver an acoustic signal to the user to reliably indicate to him at least the start and end of the sequence of movements. At least in the preparation of the hitting phase in which the ball-hitting implement hits the ball, for a correctly maintained sequence of movements, the centrifugal forces are so great that a visible and perceptible separation of the component parts takes place after passing through the obstruction. The separation provides the user, in the sense of biofeedback or feedback, with a monitoring possibility for correctly passing through the desired movement. Especially in the critical transition area between the actual starting phase of the stroke and the later hitting phase, the monitoring means is in action and delivers the required feedback for the desired correct sequence of movements.
The device of the present invention is fixed on the one hand on the hitting implement, preferably in the area of the transition between the other part of the implement and the grip of the implement, and on the other on the upper arm of the user, preferably in the area above the elbow joint, for righthanders the upper left arm, and for lefthanders preferably the upper right arm. While carrying out the actual swinging motion for producing the ball-hitting force, the centrifugal forces, occurring in the system of the implement, the user and the device, are used to trigger the monitoring means. Depending on its respective system state, the monitoring means relays feedback to the user who evaluates the pertinent feedback to learn the correct sequence of movements with the ball-hitting implement.
In one preferred embodiment of the device of the present invention, the monitoring means has at least two component parts which can be detached from one another and which interact with one another by a force means. At least at the start and end of the sequence of movements, the detachment of the component parts is obstructed or their joining takes place in an accelerated manner. The force means consequently opposes the centrifugal force. Both the detachment of the component parts and the later joining deliver an acoustic signal to the user to reliably indicate to him at least the start and end of the sequence of movements. At least in the preparation of the hitting phase in which the ball-hitting implement meets the ball, for a correctly maintained sequence of movements the centrifugal forces are so great that a visible and perceptible separation of the component parts takes place after passing through the obstruction to provide the user, in the sense of biofeedback or feedback, with a monitoring possibility for correctly passing through the desired sequence of movements. Especially in the critical transition area between the actual starting phase of the stroke and the later hitting phase, the monitoring means is effective and delivers the required feedback for the desired correct sequence of movements.
In one especially preferred embodiment of the device of the present invention, the force applied by the force means tries to keep the component parts permanently in contact with one another. The amount of force can be preset by an adjustment means. The adjustment means makes it possible, within definable limits, to adapt the device to the biophysical circumstances of the respective user so that the device can be used for children, adolescents and adults, even without major changes of a structural type.
In another especially preferred embodiment of the device of the present invention, the component parts in each of their positions relative to one another are joined to one another by a connecting means. As part of the force means, the connecting means applies a reset force to the component parts. In this way, in the area of the end phase or the so-called finish in which the hitting phase ends after hitting the ball, the monitoring means will again assume its original system state in which the component parts adjoin one another to obstruct the travel through a following sequence of movements again. The indicated reset force in the so-called finish range causes the two component parts of the monitoring means to be audibly brought together to notify the user acoustically of the end of the swinging motion. The device is then available to the user to be used again.
Other objects, advantages and salient features of the present invention will become apparent from the following detailed description, which, taken in conjunction with the annexed drawings, discloses a preferred embodiment of the present invention.
Referring to the drawings which form a part of this disclosure:
FIGS. 1a, b, c and d are frontal elevational views of the position of an individual practicing with a ball-hitting implement in the form of a golf club divided in four successive phases of movement, with a device according to an embodiment of the present invention;
FIG. 2 is an enlarged, side elevational view of the device of FIG. 1, affixed to a golf club with a monitoring means;
FIG. 3 is an exploded, perspective view of the parts of the monitoring means of the device of FIG. 2;
FIG. 4 is a side elevational view in section of each of the two component parts of the monitoring means of FIG. 3;
FIG. 5 is an enlarged, partial side elevational view in section of the component part portion within the circle designated "X" in FIG. 4; and
FIG. 6 is an enlarged exploded, perspective view of the fixing clamp within box "Y" in FIG. 2.
The device of the present invention shown in the figures is to be used especially for golf clubs. This device can also be used for other types of ball-hitting implements, for example for baseball bats and tennis rackets.
The views of FIGS. 1a to d are in the nature of snapshots showing the execution of a ball-hitting movement with a device 10 according to the present invention. The device 10 has its two ends 12 and 14 is fixed on a body part in the form of the upper arm 16 of the user and on the club 18, respectively. The sequence of movements shown in FIGS. 1a to d for a right-hander can, of course, also be carried out for left-handers with the corresponding requisite changes.
FIG. 1a shows the user with the club 18, after executing the drawback phase with backswing, at the start of the so-called downswing. The pivot of the club motion is in the vicinity of the shoulder of the user. In the course of the follow through, the left arm is extended when the sequence of movements is correct. The initiation of just this movement is signaled to the user by the monitoring means. The two components pieces 22, 24 moving apart with an audible metallic sound as the magnetic force acting between them is overcome.
FIG. 1b shows the user with the club 18 during a superimposed second rotary motion, when within the follow through movement the hands of the user are roughly at hip height. In this rotary motion, the club 10 is moved around a pivot in the wrists of the user. The sequence of movements in this respect corresponds to what is shown in FIG. 1c.
The component parts 22, 24 are joined by a connecting means 26 applying a reset force to the component parts 22, 24, as shown in FIG. 1d, after the user has hit the ball and followed through with the club in sequence in front of the body. The component parts are again brought together in the so-called finish (end phase). The two component parts 22, 24 being brought together is again linked to a perceptible metallic clicking as an acoustic signal as soon as they make contact with one another.
The above-described sequence of movements basically has a model-like nature in order to illustrate the fundamental relationships. Especially in professional sports, there are conventionally deviations from the described sequence of movements. However, this deviation is immaterial for the use of the training device controlled by centrifugal force, as in the present invention.
FIG. 2 shows the device 10 in its entirety fixed on the golf club 18 (shown only partially). Proceeding from the first end 12, which is fixed on the upper arm of the user, a fixing means 28 in the form of an adhesive fastener band 30 with a rectangular eye 32 of plastic material is attached to its one end. The free end 34 of the adhesive fastener band 30 is inserted through eye 32 and returns after encompassing the upper arm. Then, free end 34 is pulled back so that the adhesive fastener means 38, attached to the outside periphery 36 of the adhesive fastener band 30, engage to the free end 34. The ends of a cloth strip 40, forming a loop, are attached to the outside periphery 36 of the adhesive fastener band 30. A metal eye 44 is attached to another loop 42 of the cloth strip. Eye 44 is used for lengthwise adjustment of the cloth strip 40. Strip 40 is inserted past a tongue-like cross brace 46 of the eye 44. This arrangement prevents the strip 40 from slipping through. This adjustment enables matching of the device to the conditions of the body of the user.
Furthermore, the cloth strip 40 passes through and pulls on a U-shaped metal holder 48. A spring hook 50 with a leaf spring closure 52 is pivotally supported on holder 48. The spring hook 50 here fits through a metal clip 54 with two open ends 56 attached to the opposing points of the outside periphery of a metal truncated hollow cone 58 (FIG. 3). The cone can be fixed, after it has been turned over the end piece 60 of the base body 62 of the component part 22 of the monitoring means 20, by two metal cotter pins 64. The cotter pins are driven opposite to one another and perpendicular to the axis of symmetry of the truncated hollow cone 58 through openings 66. On the part of the base body 62, these cotter pins 64 slide in a peripheral groove 68, which is especially apparent in FIGS. 4 and 5. A peripheral or annular projection 70 prevents the truncated hollow cone 58 from being withdrawn or separated from the base body 62.
The two component parts 22 and 24, with base bodies 62 and 72 are shown in FIGS. 3 and 4, and are joined to one another by the connecting means 26 as part of a force means which is designated 73 as a whole. The force means includes an elastic cord 74 guided or extended through the cylindrical recesses 76 of the component parts 22, 24. The recesses are located along the lengthwise axis of the component parts. The elastic cord is attached by fixing means 78. A metal ring 80 is on one piece of the same cross section of the base bodies 62, 72. Each base body is formed of laminated plastic, and has a cross section which tapers in the direction to its outer end. In the area of the tapering cross sections, the base bodies 62, 72, recesses 82 are spaced uniformly over the periphery. The recess bottoms 84 are each spaced the same distance from the lengthwise axes 86 of the component parts. A rib structure is thereby formed which extends into the solid end pieces 60. The rib structure yields a weight reduction which facilitates handling for the conical component parts 22, 24.
For the component part 22, the assigned metal ring 80 on its side facing the base body 62 has an end piece 88 with a tapering cross section, as can also be seen in FIG. 3. An outside thread 92 is provided on the outside periphery 90 of this tapered cross section, and is used for screwing to an inside thread 96 provided in the cylindrical recess 94 in the base body 62. A thrust piece 100 is embedded, spring-loaded in the bottom 98 of the recess. When the base body 62 is screwed with the assigned metal ring 80, hemispherical head 102 of thrust piece 100 fits into the conical recesses 104. Recesses 104 are provided on the side of the tapered cross section of the metal ring 80, which side faces the bottom 98 of the recess. These recesses are located diametrically relative to the lengthwise axis 86 of the component parts by an angular amount which is the same in each case.
A ring magnet 106 is another primary part of the force means 73, has the same cylinder axis, and is countersunk into the metal ring 80 attached to the base body 72 and assigned to the component part 24. Ring magnet 106 applies an attractive force to the other metal ring 80 assigned to the component part 22. On the component part 24, a cylindrical plastic piece 108 projects in the direction of the other component part 22 out of the base body 72 along the lengthwise axis 86 of the component parts. Cylindrical piece 108 has a conical end piece 110, which together with a recess 112, provide a guide means 113, and is partially surrounded peripherally by the metal ring 80 and the magnet 106. The part of the plastic piece 108 projecting beyond the metal ring 80 with the magnet 106 along the lengthwise axis 86 of the component part, when the component parts 22 and 24 are brought together, then grips the cylindrical recess 112 of the other or second metal ring 80 assigned to the component part 22. As part of the force means 73 with the first metal ring 80, that part interacts with the ring magnet 106. Recess 112 runs along the lengthwise axis 86 of the component part. The ring surface 114 of the conical end piece 110, which surface faces the component part 22, in this type of passage is in contact with the bottom 98 of the cylindrical recess 94 in the base body 62 before the outside thread 92 of the metal ring 80 engages the inside thread 96 of the base body 62. In this manner, ring surface 114 and bottom 98 adjoin one another flat with the facing ring surfaces 116, 118 of the metal ring 80 or of the base body 62. In a further screwing-in process in which the two threads 92, 96 are moved by twisting the base body 62 against the assigned metal ring 80. The second base body 72 is supported on the first base body 62. The two component parts 22, 24 are located against one another, spaced apart. The thrust piece 100 projects out of the recess bottom 98 into the respectively assigned conical recess 104. In the manner of a ratchet, definable adjustment of the magnetic force holding the two component parts 22, 24 together is possible. The ratchet approach results in that the magnetic force, once set, does not change unintentionally during operation of the device 10. In this way, it could adversely affect the operation of the device 10. The device 10 can be matched to the special user conditions, especially with respect to body sizes and body forces present at the time, by way of the described magnetic force adjustment means 120.
The end 14 of the component part 24 facing the club 18 likewise has, as in the component part 22, a truncated hollow cone 58. Cone 58 is guided on the end piece 60 by metal cotter pins 64 sliding in a peripheral groove 68, with a metal clip 54 fixed on it. A steel ring 122 extends through metal clip 54 and extends through round openings 124, 126 on two clamp sheets 128, 130 of a fixing clamp 132, as is shown in FIG. 6. This fixing clamp 132 is used to fix the device 10 on the club 18. For this purpose, the two clamp sheets 128 and 130, with their inner base surfaces 134, are placed on one another. A cylindrical screw piece 136 projects vertically from the inner base surface 134 of the first clamp sheet 128, and extends with the thread through another recess 138 of the second clamp sheet 130 so that the two clamp sheets 128, 130 can be detachably secured on one another using a lock nut 140, as the circular openings 124, 126 lie on top of one another. The side surface 142 of the clamp sheet 130 adjoins the projection 144 which projects over the side surface of the clamp sheet 128 to additionally prevent the two clamp sheets 128, 130 from sliding off one another. On the side of the clamp sheets 128, 130 facing the club 18 they are provided with equal-sided angle pieces 146. The angle pieces project at an angle of 45� from the clamp sheets. Each angle piece includes an angle of 90� such that, when the clamp sheets 128, 130 lie on one another, the angle pieces enclose a cavity with a square base surface to hold a piece of the club 18. To prevent damage or stick on the club 18, the angle pieces 146 have rubber cushions 150 which cover their entire inner surfaces 148.
For purposes of illustration, the manner of action of the device 10 from FIGS. 2 and 3 during the various phases of the sequence of movements shown in FIGS. 1a to 1 d is discussed. A device 10 is fixed on the club 18 and on the upper arm 16 of a right-handed user, adapted by means of the ratchet approach to his physical conditions. In the ratchet approach, the component parts 22, 24 are spaced apart from one another in definable increments by the adjustment means 120. Twisting of the base body 62 of the component part 22 against the metal ring 80, which is assigned to it, causes a change of the distance between the metal rings 80. The associated change of the force which acts between the component parts 22, 24 allows the user to adapt to his individual circumstances.
In FIG. 1a this user is in the initial phase of the sequence of movements and after the drawback motion with the club 18 executes a first type of lever motion of his arm around the left shoulder area, during which the monitoring means 20 is not triggered.
In FIG. 1b the user, with his hands roughly at hip height, in the sequence of his movements reaches the hitting phase in which the first type of lever motion is superimposed by a second type during which the club 18 is moved around the wrists of the user. The centrifugal motion triggers the monitoring means 20, which is now tensioned tautly between the upper arm of the user and the club 18. If the amount of force which engages the monitoring mean 20 exceeds the magnetic force which obstructs loosening of the component parts 22, 24, as for example in the transition from the position which is shown in FIG. 1a into the position which is shown in FIG. 1b, the component parts 22, 24 are separated from one another in a clearly audible manner. FIG. 1c shows the user still in the hitting phase of the sequence of movements with the now separated component parts of the monitoring means 20 which is attached to the club 18. Furthermore, FIGS. 1b and 1 c illustrate that separation of the component parts 22, 24 takes place in the visual field of the user; his exercise of monitoring is improved in addition using this optical signal.
After hitting the ball in the end phase of the sequence of movements, the club 18 is swung forward first in front of the body of the user and then, as shown in FIG. 1d, is guided on the left side to behind the body. By mobilization of the reduction of the centrifugal force, the component parts 22, 24, which are joined to one another during the entire sequence of movements regardless of their relative position to one another by a connecting means 26 in the form of an elastic, extended connecting element, especially an elastic cord 74, are again caused to approach one another. By the plastic piece 108 with the conical end piece 110 fitting into the recess 112, the guide means 113 provides for the two component parts 22, 24 being brought together again such that in their initial position they are located along a common lengthwise axis. After the component parts 22, 24 are brought visually and audibly together, the device 10 is immediately available again for execution of the sequence of movements.
The above described sequence of movements is of a purely model nature for a more detailed explanation of the invention. Depending on the individual circumstances, it is also possible to deviate from this model without adversely affecting the functionality of the device as claimed in the invention.
While one embodiment has been chosen to illustrate the invention, it will be understood by those skilled in the art that various changes and modifications can be made therein without departing from the scope of the invention as defined in the appended claims.

The Marvelettes
The Marvelettes career epitomized the haphazard progress endured by many of the leading girl-groups of the early 60s. Despite enjoying several major US hits, they were unable to sustain a consistent line-up, and their constant shifts in personnel made it difficult to overcome their rather anonymous public image. The group was formed in the late 50s by five students at Inkster High School in Michigan, USA: Gladys Horton, Georgeanna Marie Tillman (d. 6 January 1980), Wanda Young, Katherine Anderson and Juanita Grant. They were spotted at a school talent show by Robert Bateman of the Satintones, who introduced them to Berry Gordy, head of the fledgling Motown Records organization. Bateman co-produced their early releases with Brian Holland, and the partnership found immediate success with Please Mr Postman - a US number 1 in 1961, and Motowns biggest-selling record up to that point. This effervescent slice of pop-R&B captivated teenage...

"Something tremendous is happening in India, and Das, with his keen eye and often elegant prose, has his finger firmly on the pulse of the transformation."
—The New York Times
Modi a 'calculated risk,' says Indian business leader: CNN
India is taking a "calculated risk" with the election of Narendra Modi as prime minister, Indian business leader and public intellectual Gurcharan Das told CNN's Christiane Amanpour on Monday.
"It's obviously a risk you take when you bring in a strong person. But I believe that India has enough constrain...
Gurcharan Das on the differences between India and China at Emory University
International best-selling author and public intellectual Gurcharan Das speaks with Emory professor of religion Paul Courtright on the dramatic differences between India and China on all levels of society, politics, and economics.
"India is a bottom-up success, while China is a top-down success. India is a success of the people, despite the state; China is a success because of the state," says Das.
Das visited Emory as a Halle Distinguished Fellow in September 2012 to give a public talk, "India Grows at N...
New Book
'Why should it take us 15 years to get justice in the courts or 12 years to build a road?' argues Gurcharan Das.…You need a strong state and a strong society, so the society can hold the state accountable. India will only get a strong state when the best of society join the government and China will only get a strong society when the best Mandarins go into the private sector.' --Tom Friedman, New York Times, 6 February 2013
'The book raises some excellent questions...India is an open tolerant country. So why does liberalism not flourish there? Mr Das insists that liberal ideas offer the clearest answer to many of India's woes. Corruption, for example, will not be beaten with a big, new authoritarian bureaucracy, as anti-graft protesters want. Instead discretionary powers must be wrested from dodgy bureaucrats and politicians, the state made smaller, and markets allowed, openly and freely...Mr Das's celebration of liberalism is admirable.' --The Economist, 10 Nov 2012
"Das has written a timely book that deserves to be widely read. And it has its share of hard-headed proposals....Simply calling for less government is no answer, says Das. It needs also to be strong. Indian capitalism needs an honest referee...India has much to celebrate nowadays but also faces a cacophony of institutional challenges....Das's core argument is right and urgent." --Ed Luce, Financial Times, 25 January 2013

What was supposed to be a routine cabinet expansion this week turned into a bold shake-up. The big change is at the ministry of human resource development where the affable Prakash Javadekar has replaced the combative Smriti Irani. India has been unlucky in the poor quality of its education ministers. Irani was always the wrong choice and she did not help by picking a fight with everyone. She has...
A few months ago, I was at an attractive event in Delhi, surrounded by elegantly dressed, articulate Indians and a sprinkling of foreigners. Into this privileged gathering walked an awkward young man who someone recognized from Hindi television. He seemed to be lost and was mostly ignored until someone provoked him and there followed a loud, ugly argument over the JNU controversy. He put up a spir...

There are a lot of restaurants on Thayer street, where most students go.
{{review.SectionLabel}} at {{review.EntityName}}:
Sorry, there are no reviews.
Although most RISD kids stick pretty close to school, there are still a surprising variety of restaurants that are cheap enough for students found on Main, Thayer, and Wickenden streets. Thayer Street is one long chain of restaurants and shops that spans several blocks in the heart of the Brown/RISD radius. In one block, students will walk past Indian, Mexican, pizza, Mediterranean, and Middle Eastern food, all of which are small unique restaurants. In fact, other than the occasional McDonald's downtown, you might have to go outside Providence proper to find a chain restaurant.
Because Johnson & Wales has a culinary academy, there is a wealth of interest and innovation in the immediate area that is constantly replenished, and there are always new and interesting restaurants popping up. There is also a large Asian population that feeds some of the best Asian and Indian restaurants in the area. Finally, the large Italian population makes Federal Hill a Providence version of Little Italy. Thrown into the mix are a few college-hangout places, such as Meeting St. Café and Antonio's, and a few four-star gourmet places, such as Pastiche, which is a dessert restaurant, and you've got an extremely rich and diverse selection to choose from. It's impossible to get bored, but it helps to have a car or a friend with a car if you want to get to some of the more out-of-the-way places.
