ABSTRACT:
A power door safety sensing strip with a bracket strip for attachment to the face of a power operated garage door. The sensing strip includes a flexible insulating tubular member having a bell-like shaped cross section with a wide inner face. A flat insulating member fastened to a narrow section of the bell-like member extends to the wide inner face. Conductive surfaces on the wide inner face and on the flexible insulating member are moved into contact upon deformation of the bell-like member, thereby providing electrical contact. A Z-shaped bracket to attach the sensing strip to the face of a power operated door has one leg adapted to be attached to the door face. Another leg of the bracket, formed with a U-shaped receptacle, receives and holds the sensing strip so that it extends a short distance beyond the door edge.
