ABSTRACT:
An audible signaling device for elevator cars of the type having an access opening and a door slideably carried by the elevator car and movable from a closed position to an open position. The audible signaling device comprises a housing mounted to the elevator car door and movable therewith. The housing includes a striker actuated gong which is operated in response to a pivotally mounted lever arm which, in turn, causes the striker to engage the gong when the door is moved to the open position. A magnet is positioned with respect to the open door such that the pivotally mounted lever arm engages the magnet and actuates the gong signaling the opening of the door. In one embodiment of the invention the magnet is located at the main floor entry to the elevator car such that, upon opening of the elevator car door, the gong is actuated to signal that the car is at the main floor. In a second embodiment of the invention the magnet is carried on the movable elevator car and is adapted to actuate each time the elevator car door is opened.
