First Claim
Patent Images
1. Tactile actuator apparatus for mounting on the lower edge of a one-piece overhead door driven by an automatic operator, comprising:
- an elongated base for mounting from the door along the lower edge and including electrically insulating means;
a sensor channel projecting longitudinally along the base and constructed of an electrically conductive resilient wall configured to form a hollow elongated interior chamber, said wall being further responsive to application of a predetermined force along the length thereof to flex inwardly along an actuation path; and
an elongated electrically conductive contact strip device disposed in said chamber, mounted on said base and projecting therefrom to form a plurality of free edges disposed in said actuation path such that application of said predetermined force from any of a plurality of predetermined angles will deflect said wall through said actuation path to contact at least one of said free edges of said contact strip.

Abstract
An electrically insulating base for mounting to the lower edge of a one-piece garage door and formed with an elongated, electrically conductive, inwardly protruding elliptical in cross section hollow symmetrical channel formed with an interior chamber. Mounted within the chamber is an elongated J-shaped strip contact extending longitudinally relative the channel and disposed below the center line thereof such that deflection interiorly of the wall of the channel will cause the wall to engage the strip contact.
