Abstract:
A directional lock for a caster. The caster has a wheel assembly including a wheel rotatable about a wheel axis and a housing for supporting the wheel. The housing defines a cavity for receiving a portion of the wheel. Also, the caster includes a stem supported by the housing and positionable in a chassis element, the wheel assembly being pivotally attached to the stem. The directional lock has an engagement portion and a base portion coupled to the engagement portion such that the engagement portion is movable relative to the base portion. The engagement portion is for engaging the wheel assembly to locate the wheel assembly in a predetermined position relative to the chassis element. The base portion is adapted to cooperate with the chassis element to maintain the engagement portion in a predetermined relation to the chassis element.
