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.

1. A caster locking mechanism for a patient care bed, the caster locking mechanism comprising: an engagement foot movable between a retracted position and an extended position for lifting a caster assembly off of a support surface;a lock bar movable in a first direction from an unlocked position to a locked position to move the engagement foot from the retracted position to the extended position;a release bar movable in the first direction from an initial position to a release position to move the engagement foot from the extended position back to the retracted position; anda lock and release assembly, including: a guide plate defining a lock and release slot;a rocker including a protrusion slidably disposed within the lock and release slot, the rocker operably coupled to the lock bar such that moving the lock bar from the unlocked position to the locked position slides the protrusion of the rocker through the lock and release slot from a first position to a second position to lock the lock bar in the locked position and the engagement foot in the extended position; anda release member including a protrusion slidably disposed within the lock and release slot, the release member operably coupled to the release bar such that movement of the release bar from the initial position to the release position slides the protrusion of the release member through the lock and release slot and into contact with the protrusion of the rocker to urge the protrusion of the rocker from the second position back to the first position, thereby returning the lock bar to the unlocked position and the engagement foot to the retracted position. 2. The caster locking mechanism according to claim 1, wherein the lock and release slot defines a L-shaped configuration having a vertical portion and a horizontal portion, and wherein, moving the lock bar from the unlocked position to the locked position slides the protrusion of the rocker from a closed end of the vertical portion of the lock and release slot, through the vertical portion of the lock and release slot, and into the horizontal portion of the lock and release slot to lock the lock bar in the locked position and the engagement foot in the extended position. 3. The caster locking mechanism according to claim 2, wherein movement of the release bar from the initial position to the release position slides the protrusion of the release member from a closed end of the horizontal portion of the lock and release slot through the horizontal portion of the lock and release slot and into contact with the protrusion of the rocker to urge the protrusion of the rocker from the horizontal portion of the lock and release slot to the vertical portion of the lock and release slot, thereby returning the lock bar to the unlocked position and the engagement foot to the retracted position. 4. The caster locking mechanism according to claim 3, wherein, the lock bar is biased towards the unlocked position such that the protrusion of the rocker is biased towards the closed end of the vertical portion of the lock and release slot once disposed within the vertical portion of the lock and release slot, thereby returning the lock bar to the unlocked position and the engagement foot to the retracted position once the protrusion of the rocker is disposed in the vertical portion of the lock and release slot. 5. The caster locking mechanism according to claim 1, wherein the lock bar includes a yoke pivotably coupled to the guide plate at a first location along the yoke via a first pin. 6. The caster locking mechanism according to claim 5, further including a second pin pivotably coupled to the yoke at a second location along the yoke, the second pin slidably disposed within a guide slot defined within the guide plate. 7. The caster locking mechanism according to claim 6, wherein the rocker is pivotably coupled to the yoke at the second location along the yoke via the second pin. 8. The caster locking mechanism according to claim 6, further including a leg defining a first end and a second end, the first end of the leg pivotably coupled to the yoke at the second location along the yoke via the second pin, the second end of the leg coupled to the engagement foot. 9. The caster locking assembly according to claim 1, wherein the release member is fixedly engaged to the release bar, the release member pivotably coupled to the guide plate via a third pin. 10. The caster locking assembly according to claim 1, wherein the guide plate is configured to fixedly engage a base bar of a leg assembly of a patient care bed.
