ABSTRACT:
A handcart wheel-mounting apparatus includes a wheel mounted by means of a number of latches each biased by means of an elastic element, on a hub member in turn mounted by means of an annular washer and a cap, on a wheel shaft mounted on a wheel support. The hub member comprises a rim, an axial bore formed therethrough, a tubular bearing coaxially formed therethrough about the axial bore, a plurality of recesses formed therein about the axial bore, and a plurality of holes radially formed therethrough so that each of the holes communicates with a corresponding one of said recesses. A number of elastic elements are received in the recesses. A number of latches each are formed on a corresponding one of the elastic elements and the latches are biased through the holes by means of the elastic elements. The wheel shaft is inserted through a passage formed transversely through the wheel support, the annular washer, and the axial bore. Then, a tip of the wheel shaft is firmly fitted in the cap. Thus, the hub member is firmly mounted on the wheel shaft. The wheel is co-axially formed with a tubular portion and a number of sockets are transversely formed through the tubular portion. The hub member is mounted in the tubular portion having the holes aligned with the sockets. Then, the latches are inserted through the holes into the sockets. Thus, the wheel is mounted on the hub member.
