Abstract:
1. A wheel-mounting assembly comprising: a pivot shaft; a frame-connecting part; a wheel-mounting part pivoted to said frame-connecting part through said pivot shaft and formed with a retaining hole; a limiting member mounted movably on said frame-connecting part and aligned with said retaining hole when said frame-connecting part rotates relative to said wheel-mounting part about said pivot shaft to a predetermined position, said limiting member being movable relative to said frame-connecting part and said wheel-mounting part between a limiting position, in which said limiting member extends into and engages said retaining hole, and a non-limiting position, in which said limiting member is disposed outwardly of and is disengaged from said retaining hole; an urging member for urging said limiting member to move from the non-limiting position to the limiting position; a controlling member pivoted to said frame-connecting part and rotatable relative to said frame-connecting part between a retaining position, in which said limiting member is retained at the non-limiting position by said controlling member, and a releasing position, in which said limiting member is released from being retained by said controlling member so as to be movable from the non-limiting position to the limiting position through urging action of said urging member; and a locking member pivoted to said controlling member and rotatable relative to said controlling member between a locking position, in which said locking member engages said frame-connecting part so as to retain said controlling member at the retaining position, and an unlocking position, in which said locking member is disengaged from said frame-connecting part so as to permit movement of said controlling member from the retaining position to the releasing position.
