  • Patent number: 4149222
    Abstract: A bed light safety apparatus which includes a normally wall mounted lighting fixture. The upper rearward edge of the fixture is pivotally mounted to a plate adapted for attachment to a wall. One embodiment of the apparatus includes a switch carried by the fixture. When used in conjunction with a hospital bed or the like which is power operated to a raised position, the switch is made a part of the electrical circuit for the bed drive means. In the event equipment carried by the bed strikes the fixture on raising of the bed, the consequent pivotal movement of the fixture causes the switch to open the circuit to the bed drive means and halt further raising of the bed. In other embodiments the safety apparatus may include visual or auditory alarms actuable by a switch in the fixture.
