A plastic wheel (22, 122) and wheel mounting sleeve (27, 27a, 127) used to releasably secure the wheel (22, 122) onto an axle (23, 123).

A plastic wheel (22, 122) and wheel mounting sleeve (27, 27a, 127) used to releasably secure the wheel (22, 122) onto an axle (23, 123). The wheel mounting sleeve (27, 27a, 127) preferably includes a resilient, radially displaceable, axially extending, cantilevered finger (46, 146) which includes an axle-engaging lug (55, 155), while a wheel-engaging shoulder is provided on an annular rib 101, 201. The respective sleeve shoulders cooperate with oppositely facing shoulders on the wheel so as to latch the sleeve (27, 127) to the axle (23, 123) and the wheel (22, 122) to the sleeve (27, 127). The sleeve (27, 127) and sleeve-receiving bore (39a, 39b, 139a, 139b) are radially inwardly stepped on the inner side (66, 166) as compared to the outer side (67, 167) of the wheel. Assembly can be accomplished without any tools, and a pointed tool can be used to puncture a skin (195) in a passageway (191) so as to enable release of the sleeve (27, 127) and wheel (22, 122) from the axle (23, 123).

1. In a wheel mounting sleeve including a sleeve body having an inner end and an outer end and formed and dimensioned for mounting through wheel bearing bore in a wheel and into telescoped relation over an axle, said sleeve having at least one axle-engaging shoulder thereon retaining said sleeve on said axle and at least one wheel-engaging shoulder thereon retaining said wheel on said sleeve, the improvement comprising:said sleeve body being formed with at least one resilient, radially displaceable, axially extending, cantilevered finger, said axle-engaging shoulder extending radially inwardly from said finger proximate said outer end of said sleeve and said wheel-engaging shoulder being an annular radially outwardly projecting rib proximate said inner end of said sleeve, and said inner end of said sleeve being formed with at least one slot therein extending from said inner end toward said outer end by a distance sufficient to enable inward flexing of said rib for mounting to said wheel.
