Abstract: A locking mechanism system for a caster or similar wheeled device. The subject caster or the like is provided with a wheel containing a plurality of detents or grooves that is mounted to a fork having an aperture. The locking mechanism is mounted to the fork such that a retractable locking pin may move in and out of the aperture. A slidable lever, containing an internal cam moves the spring biased locking pin between an unlocked and locked position such that the locking pin engages the wheel detents in the locked position, thus preventing the wheel from rotating.
