  • Exit device having a deadbolt as its securing member
    Patent number: 5605362
    Abstract: This exit device has a press bar and an elongated deadbolt adapted to be mounted horizontally adjacent the free end of the door and a pivoted retractor blade inward of the door. The blade is pivoted by the press bar and engages with its nose a projecting surface on the deadbolt and retracts the deadbolt. The blade also has a keeper contact surface which, as the door closes, is contacted by the keeper and the blade is pivoted inward to retract the deadbolt. The retractor blade also serves as an anti-friction bearing having a peripheral portion which rolls against the deadbolt and counters against the inward force on the deadbolt opposing to the opening force on the door.
