US 2012/0237285 A1 · FULL BREAKOUT ARM FOR AUTOMATIC DOORS

Abstract

A full breakout arm (1) having a sliding arm (4) that is attached to a door (2) along an upper edge (5) of the door. The sliding arm has a first end (6) fixedly and pivotally attached to a hinged side of the door. A release mechanism (9) is mounted to the opposite side of the door. A channel (13) located along the sliding arm is slidably and pivotally attached to a first end (15) of a rotating arm (14) via a pivot point (16) that slides within the channel. A second end (17) of the rotating arm is attached to a motor (3). When excess pressure is placed on the door, the release mechanism disengages from the second end of the sliding arm and the first end of the sliding arm remains fixedly and pivotally attached to the door while the pivot point of the rotating arm slides back and forth within the channel of the sliding arm.
