when was the first suitcase with wheels invented
Baggage Luggage carriers – light-weight wheeled carts or harnesses on which luggage could be temporarily place or that can be temporarily attached to luggage – date at least to the 1930s, such as in US patent 2,132,316 "Luggage carrier" by Anne W. Newton (filed 1937, published 1938).[5] These were refined over the following decades, as reflected in patents such as US patent 2,650,105 A "Luggage carriage" (filed 1949, published 1953)[6] and US patent 2,670,969 "Luggage carriage harness,[7] both by Kent R. Costikyan.[8] However, the wheels were external to the suitcases. Patents were published for wheeled luggage – a wheeled trunk in 1887, and a wheeled suitcase in 1945 – but these were not successfully commercialized.[9]
