Abstract:
1. A method for preventing damage to an adjacent wall surface of an electrically operated bed comprising: attaching a normally closed/momentarily open switch assembly to an electrically operated bed frame at a desired location, wherein said switch assembly is in electrical communication with a controller, a motor and a control panel associated with said hospital bed frame and is further in electrical communication with one of an AC or DC power source, said motor is in electrical communication with said controller and/or said control panel such that when said switch assembly is activated from its contact with an adjacent wall surface or from its proximity to said adjacent wall surface, electrical power to said controller and/or said control panel is interrupted thereby interrupting electrically operable bed frame functions, and thereby stopping the bed frame from being maneuvered any further and thereby preventing damage to the wall surface, and wherein normal operations of the electrically operated bed frame resume when said bed frame is moved away a predetermined distance from said wall surface.
