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.

Abstract: A power door sensing strip incorporates a pair of electrical conductors positioned in a sealed plastic tube and supported in a molded foam block so that external forces result in contact between the conductors. Reliable operation is afforded by the absense of internal supports between the conductors. Further, short circuits caused by moisture and contaminants entering the foam through breaks in an outer jacket are eliminated. Trimmable tails and electrical connections on the ends of the strip enable the strip to be used with doors of varying widths and for non-handed installation.
