  • Patent number: 5975542
    Abstract: A wheel-supporting hanger for utilization on the frame of a roller skate, this hanger having an upper mounting portion as well as front and back portions. A central cavity is defined in the front portion of the hanger, in which an axle-receiving member is operatively mounted in a cantilever manner. A wheel-supporting axle protrudes outwardly in a cantilever manner from the axle-receiving member, with a screw utilized on the outer end of the axle for retaining a skate wheel in an operative manner on the axle. A structural member is located in an upper part of the cavity, defining a substantially flat undersurface in a relatively closely spaced relationship to the axle-receiving member. The cantileverly mounted axle-receiving member, because of the mounting of the axle therein, is permitted to flex upwardly as well as to move laterally to a controlled extent should the wheel mounted on the axle encounter an obstacle or obstruction.
