Abstract
A sleeve for a caster, insertable into a cavity or hole in a furniture leg; the sleeve is generally tubular with a closed upper end and an open lower end; the sleeve is slotted longitudinally, forming diametrically opposed legs which are flexible toward and from each other; the legs have upper and lower prongs, the upper ones projecting upwardly and the lower ones projecting downwardly, both biting into the surface of the cavity and aiding in normally retaining the sleeve in the cavity; the upper prongs also releasably retain the caster stem in the sleeve; it also has transverse slots at the closed upper end communicating with the longitudinal slots.
Claims7
A caster sleeve for use in conjunction with a caster having a stem with a head on a shank, the head being of greater diameter than the immediately adjacent portion of the shank, comprising,
- a generally tubular integral sleeve adapted for insertion into a cavity in a furniture piece and having a closed upper end and an open lower end, the closed upper end being continuous through its transverse extent,
- the sleeve being slotted longitudinally on diametrically opposite sides from a position adjacent the closed upper end to and through the open lower end forming a pair of diametrically opposite legs flexible toward and from each other,
- the legs including upper and lower prongs struck from the integral portions of the legs, the prongs having points normally adjacent the outer surface of the sleeve and elbows normally extending inwardly of the inner surface of the sleeve, whereby in response to insertion of the caster stem into the sleeve, the head of the stem forces the prongs outwardly into penetrating engagement with the wall of the cavity, and the elbows of the upper prongs remain at least slightly inwardly of the inner surface of the sleeve and releasably retain the caster in the sleeve.
A caster sleeve for use in conjunction with a caster having a stem with a head on a shank, the head being of greater diameter than the immediately adjacent portion of the shank, comprising,
- a generally tubular integral shell adapted for insertion into a cavity in a furniture piece and having a closed upper end and an open lower end, the closed upper end being continuous throughout its transverse extent,
- the shell being split longitudinally by slots on diametrically opposite sides extending from a position adjacent the closed upper end to and through the open lower end, forming a pair of diametrically opposite legs flexible toward and from each other,
- the shell having transverse slots adjacent to but spaced downwardly from the closed upper end communicating with the longitudinal slots, and
- the legs having prongs struck from the integral portions of the legs, the prongs having points adjacent the outer surface of the shell as formed by the legs and projectable into the material of the furniture piece for normally retaining the sleeve in the cavity of the furniture piece and the caster in the sleeve.
