Abstract
A panel closure apparatus has a panel (14) for closing against a strike jamb (12). A locking element (100) is displaceable between a released position and a locked position in which contact surfaces (102, 104) of the locking element and the panel prevent opening of the panel, and are configured so that force applied to open the panel does not generate a force to disengage the locking element. Locking element (100) has an input surface (108) deployed so as to be displaced by an actuating surface (110) of panel (14) during a closing motion of the panel from the open position to the closed position. Input surface (108) moves as a unit with locking element (100) so that displacement of the input surface by the closing motion of the panel displaces the locking element towards the locked position.
Claims18
An apparatus comprising:
- (a) an opening bounded in part by a strike jamb;
- (b) a panel mounted relative to said opening so as to be displaceable between an open position in which said panel is separated from said strike jamb to leave at least part of said opening open and a closed position in which said panel closes against said strike jamb;
- and
- (c) a lock mechanism associated with said strike jamb, said lock mechanism comprising a locking element displaceable relative to said strike jamb along a path of motion from a released position in which said panel can be separated from said strike jamb to a locked position in which said locking element obstructs displacement of said panel from said strike jamb, contact surfaces of said locking element and said panel being such that a force applied to said panel directed to open said panel does not generate a force acting to displace said locking element back along said path of motion,
- wherein said locking element provides an input surface deployed so as to be displaced by an actuating surface of said panel during a closing motion of said panel from said open position to said closed position, said input surface moving as a unit with said locking element such that there is no relative motion between said input surface and said locking element, such that displacement of said input surface by the closing motion of said panel displaces said locking element towards said locked position.
