ABSTRACT:
An attaching mechanism for attaching an auxiliary wheel assembly to an axle-mounted wheel assembly includes a unitary annular disc with a plurality of apertures therein. The disc is fixed to the mounted wheel assembly for rotation therewith and includes a central opening which receives the axle. A hollow central screw member, which receives the axle, is fixed to the auxiliary wheel assembly by a plurality of struts. The struts support pivot members with ends receivable by the apertures in the attaching disc. A nut member is screwed onto the nut member and is engagable with the pivot members to pivot them into and out of interlocking engagement with the bores of the attaching disc.
