ABSTRACT:
A locking mechanism for a hospital bed is mounted on an undercarriage of the bed. The locking mechanism includes a locking pedal and an unlocking pedal, which are side-by-side one another on the undercarriage. To lock the bed in position to prevent it from rolling, one depresses the locking pedal which, through a mechanical linkage, moves a brake member having a brake pad vertically downward into contact with the floor beneath the bed, and locks the brake pad into that position. By depressing the unlocking pedal, the mechanical linkage is pulled in the opposite direction to raise the brake member and brake pad from the floor, thereby unlocking the bed.
