COMBPLATE HOLD DOWN MEANS, LIMIT SWITCH AND DEBRIS SHIELD FOR PASSENGER CONVEYORS |
摘要 |
A combplate safety device for a passenger conveyor moving relative to a frame and having a combplate mounted on the frame and movable relative to the frame in response to an obstruction to the motion of the conveyor. The combplate safety device includes a ramped hold down member which cooperates with the frame to define a rearwardly opening notch within which a complementary portion of the combplate is releasably secured against the frame in a vertically downward direction. A pair of limit switches are actuated upon a predetermined relative displacement of the combplate and the frame for deactivating the conveyor in response to the obstruction to the motion, with a compressible member being posed between the combplate and the frame to prevent accumulated debris from interfering with operation of the safety device.
