Combplate safety device

A combplate safety device for stopping a passenger conveyor, the conveyor including a combplate mounted on a frame and movable in response to an obstruction of the motion of the conveyor, the combplate safety device comprising:

• hold down means on the frame for releasably securing the combplate against the frame in a vertically downward direction;
• deactivation means operable to halt the passenger conveyor when a predetermined relative displacement of the combplate and the frame occurs, the deactivation means including a reciprocable trigger which is actuated by relative displacement of the combplate and the frame in response to an obstruction to the motion of the conveyor, and a switch means operable upon actuation of the reciprocable trigger to stop the conveyor;
• and
• complementary interlocking surfaces on the combplate and the frame to prevent debris from interfering with operation of the deactivation means.
