Abstract
A swivel caster assembly is provided with a releasable locking mechanism which selectively locks the caster assembly against rotation. A leg bushing used to support the leg of an associated appliance such as a baby stroller is rotatably supported by a caster body. The caster body has an upwardly extending locking lug recess, a transverse access aperture passing through the recess, and a transverse axle aperture. A locking lug is slidably received within the recess, and is maneuvered to a fully extended locking position and a retracted unlocking position by an arm member pivotally secured to the caster body. Force transfer between the arm member and the lug is through a spring. A locking collar is secured to the leg bushing and has a downwardly opening notch for engaging the upper end of the locking lug when extended. A pair of detent bosses extend outwardly from the caster body and engage with detent apertures formed in the arm member.
