Abstract:
A roller skate shoe, comprising:a shoe base having two receiving cavities provided thereunder at a front portion and a rear portion of said shoe base respectively operation through slot extending longitudinally alongside a sidewall of each receiving cavity, the operation through slot having a rear opening to communicate to an exterior of said shoe base; a roller arrangement fittedly received in each said receiving cavity comprising a supporting frame securely mounted on a ceiling of said receiving cavity, a wheel frame rotatably mounted on said supporting frame by a shaft, and a resilient element for applying an urging pressure against said wheel frame so as to normally retain said wheel frame in an unfolded position out of said receiving cavity; and a wheel lock releaser arrangement for securely locking said wheel frame in a rotatably movable manner selectively between a folded position and an unfolded position wherein in said folded position, said wheel frame is rotatably received into said receiving cavity and in said unfolded position, said wheel frame is rotatably extended out of said receiving cavity wherein said wheel releaser arrangement comprises: a locking member movably attached to one end of said shaft for locking up said wheel frame from being rotatable with respect to said supporting frame wherein said locking member comprises an operation button having an elongated rod portion slidably received within said operation through slot, a button head portion extending through said rear opening to an exterior of said shoe base, and a pair of protruding members formed on said elongated rod portion, each protruding member having a sloping surface selectively engageable with an end of a respective shaft upon depression of said button head portion for operating said locking member to move from a normally locking position to an unlocking position; and a resilient member which is disposed in said receiving cavity for applying an urging pressure against said locking member so as to normally retain said locking member in said locking position, wherein at said locking position, said locking member is engaged with said wheel frame for locking said wheel frame against rotational movement, and that in said unlocking position, said locking member is moved to disengage with said wheel frame so that said wheel frame is rotatable between said folded and unfolded positions.
