A hospital bed has a frame mounted on a base which includes castors. Side guards are mounted on the bed frame. The side guards are inwardly moveable and releasably lockable to narrow the hospital bed. The frame has a cam block with a recess. A latching arm is pivotally connected to linkage connecting the side guard to the frame and has a handle and a cam roller follower. The handle is rotated to move the side guard inwardly; when the roller follower engages the recess the side guard is locked in the inward position. The side guards are moveable and releasably lockable toward the foot end of the bed. A spring biased plunger on the linkage projects through a hole in a plate on the linkage. The side guards are releasably lockable in an intermediate position. The spring biased plunger projects through a hole in the cam block. |
