A sensing edge for providing a signal to a controller indicating that a forward edge of a door is obstructed during operation is provided. The sensing edge includes an elongate sheath and a first end plug assembly having a first end plug and a first end flap. The first end plug includes an engaging structure which is positioned within a first cavity of the sheath in an assembled configuration. The first end flap includes a body having a top edge and an opposing bottom edge. The top edge includes a first overhang and the bottom edge includes a second overhang. A third overhang is provided between the first and second overhangs. The first overhang is at least in partial facing engagement with an upper surface of the first end plug and the third overhang is at least in partial facing engagement with a lower surface of the first end plug.

Sensing edge

A sensing edge for providing a signal to a controller indicating that a forward edge of a door is obstructed during operation. The sensing edge includes an elongate sheath, a first end plug and a first end flap. The elongate sheath has a first end and a second end. A first cavity is located at the first end. The elongate sheath is mounted to the forward edge. The first end plug includes an inner end, an outer end, first engaging structures extending from the inner end and a first vertical groove in the outer end. The engaging structures are positioned within the first cavity in an assembled configuration. The first end flap includes a relatively flat first body and a first flange structure. The first flange structure is positioned in the first vertical groove in the assembled configuration to secure the first end flap to the first end plug.

A universally mountable sensing edge comprises an elongated sheath defining a compressible cavity with a force sensor located therein. A center securing member extends upwardly from the top wall of the sheath, has a T-shaped base portion and a removable mounting strip extending from the base portion. At least one T-shaped edge securing member extends upwardly from the top wall of the sheath at least a distance generally equivalent to the distance that the upward extension of the T-shaped base portion of the center securing member extends from the top wall of the sheath. The at least one T-shaped edge securing member is disposed proximate to at least one of the front and rear sidewalls of the sheath. The universal sensing edge is attachable to a structure compatible with the mounting strip, the base portion of the center securing member, or the T-shaped edge securing member.

Universal sensing edge

A sensing edge for providing a signal to a controller indicating that a forward edge of a door is obstructed during operation includes an elongated sheath and first and second end plugs. The elongated sheath is mounted to the forward door edge and has a first end, second end and first cavity connecting the ends. First and second spaced apart electrically conductive materials are disposed within the elongated sheath. The first end plug includes an inner end having first engaging structures positioned within the first cavity in an assembled configuration and an outer end having a first depression for housing an electronic component. The electronic component is electrically coupled to the electrically conductive materials. The second end plug includes an inner end having a sensing component and second engaging structures positioned within the first cavity in an assembled configuration. The sensing component is electrically coupled to the electrically conductive materials.

Resistor storage cavity in plug of sensing edge

A wireless, automatic door obstruction detection system for protecting a motorized door or gate by signaling various hazardous conditions and reacting to said conditions by signaling control means. The invention utilizes wireless infrared emitter, receiver and controller apparatus. Infrared pulse timing data is sent as pulse repetition rate changes depending upon battery condition. In a preferred embodiment of the invention, the photoelectric transmitter emits timed pulse groups to present control information differentiating between a good battery and a low battery condition in the wireless transmitter. A wireless photoelectric transmitter extends the time period between pulse groups to indicate a low battery condition. A low battery condition signaling thereby presents a low power drain condition allowing for an extended period of low battery condition signaling.
