Abstract
The exit device of the present invention has an elongated securing member, such as a deadbolt or the like, adapted to be mounted horizontally adjacent the free end of a door and a pivoting member inward of the door. The pivoting member has a peripheral portion which rolls against the securing member and serves as an anti-friction bearing and counters against the inward force on the securing member opposing the opening force on the door. In one embodiment, the pivoting member is pivoted by a press bar assembly, and engages and retracts the securing member. In another embodiment, the securing member is retracted by the actuating means. The pivoting member may also include a keeper contact surface which, as the door closes, is contacted by the keeper and the pivoting member is pivoted inward to retract the securing member.
