Abstract
A caster locking mechanism includes a foot movable between retracted and extended positions, a lock bar movable from an unlocked to a locked position, a release bar movable from an initial to a release position, and a lock and release assembly. The lock and release assembly includes a guide plate defining a slot, a rocker coupled to the lock bar and including a protrusion slidably disposed within the slot, and a release member coupled to the release bar and including a protrusion slidably disposed within the slot. Moving the lock bar to the locked position slides the protrusion of the rocker through the slot to extend the foot. Moving the release bar to the release position urges the protrusion of the release member through the and into contact with the protrusion of the rocker to urge the protrusion of the rocker back, thereby retracting the foot.
