ABSTRACT:
A caster is provided which makes use of a wheel that has discrete notches and that is rotatably mounted to a housing, a locking pin that is movably mounted to the housing to engage (or to disengage from) any one of the notches, and an actuator for use by a user in moving the locking pin into engagement (or disengagement). The housing also has a distinct notch into which the locking pin moves when it engages any of the wheel notches, so that locking force is borne by the housing rather than by the actuator. The notches are preferably defined in an internal surface of the wheel. Advantageously two identical wheels are used in opposition, for optimum strength and appearance.
