Roller skate having retractable wheels adapted to configure as shoe

Abstract

A wheel assembly of skate includes a wheel mounted in a casing, the wheel having an axle, two side sliding plates each including a groove adapted to mount around an open end of the axle, two springs, two links each inserted through the casing into a slot of the sliding plate, and a fastener for securing the link to one inner sliding plate. Unfastening the inner links, pulling the sliding plates to disengage with the axles with the wheels being automatically popped out of the casing by the expansion of the springs, and fastening the inner links will securely transform the skate into a roller skate. Unfastening the inner links, pressing the wheels into the casing with the springs being compressed, pushing the sliding plates to mount the grooves thereof around the axles, and fastening the inner links will securely transform the skate into a shoe.

1 . A skate four wheel assemblies each comprising:
 a casing;   a wheel mounted in the casing;   an axle with the wheel rotatably mounted therearound;   a plurality of ball bearings rotatably mounted between the axle and a hub of the wheel;   two sliding plates each abutted against either side of the casing and including a slot and a groove mounted around an open end of the axle in a retracted position of the skate;   two supports each mounted internally of the sliding plate;   two springs each put on the support;   two lock links each inserted through the casing into the slot of the sliding plate; and   a fastener for securing the link to one inner sliding plate, whereby:   unfastening the inner lock links, pulling the sliding plates to disengage with the axles with the wheels being automatically popped out of the casing by the expansion of the springs, and fastening the inner lock links will securely transform the skate into a roller skate; and   unfastening the inner lock links, pressing the wheels into the casing with the springs being compressed, pushing the sliding plates to mount the grooves thereof around the axles, and fastening the inner lock links will securely transform the skate into a shoe.   
   
   
       2 . The skate of  claim 1 , wherein the wheel comprises an inner layer formed of hard plastic and an outer layer of wear resistant plastic.
