Handcart wheel-mounting apparatus

DETAILED DESCRIPTION The present invention provides a handcart wheel-mounting apparatus which 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 defines a rim, an axial bore formed therethrough, a tubular bearing co-axially formed therethrough about the axial bore, a plurality of recesses formed therein about the axial bore, and a number of holes radially formed therethrough so that each of the holes communicates with a corresponding one of the recesses.
A plurality 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.
By such an arrangement, the handcart wheel-mounting apparatus in accordance with the present invention provides a safe wheel-mounting structure without any projecting configuration and so avoids scratching human bodies and tangling with objects such as clothing, baggage and the like.
Moreover, the handcart wheel-mounting apparatus is easy to be assembled and dismantled and is very stable so that it can carry larger loadings with bigger wheels.
