Abstract
An apparatus for locking a panel to a strike jamb includes a synchronous displacement mechanism associated with a locking element (108) which is responsive to part of a closing motion of a panel (104) from an open position towards a closed position to initiate a motion of locking element (108) towards the locked position during the closing motion of the panel prior to the panel reaching its closed position. The synchronous displacement mechanism preferably has a “deadlock state” when the locking element is in the locked position which prevents displacement of the locking element towards the unlocked position.
Claims24
An apparatus comprising:
- (a) an opening bounded on one side 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 said opening open and a closed position in which said panel closes at least part of said opening;
- (c) a locking element associated with said strike jamb or said panel and displaceable between a locked position in which said locking element locks the panel against opening, and an unlocked position in which said locking element allows opening of the panel;
- (d) a synchronous displacement mechanism associated with said locking element, said synchronous displacement mechanism being displaced by at least part of a closing motion of said panel from said open position towards said closed position, said displacement of said synchronous displacement mechanism forcing said locking element into said locked position,
- wherein the apparatus has a deadlock state which prevents displacement of said locking element towards said unlocked position, said displacement of said synchronous displacement mechanism additionally forcing the apparatus into said deadlock state, and wherein said synchronous displacement mechanism comprises:
- a lever deployed to be displaced by relative motion of said panel and said strike jamb during said closing motion;
- and an actuating linkage mechanically associated with said lever so as to be displaced by relative motion of said panel and said strike jamb during a terminal portion of said closing motion,
- and wherein a first range of displacement of said actuating linkage displaces said locking element to said locked position, and a further displacement of said actuating linkage beyond said first range achieves said deadlock state.

An apparatus comprising:
- (a) an opening bounded on one side 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 said opening open and a closed position in which said panel closes at least part of said opening;
- (c) a plurality of locking elements associated with said strike jamb or said panel, each of said locking elements being displaceable between a locked position in which said locking element locks the panel against opening, and an unlocked position in which said locking element is positioned so as not to obstruct motion of the panel to the open position;
- (d) a synchronous displacement mechanism associated with said locking elements, said synchronous displacement mechanism being displaced by at least part of a closing motion of said panel from said open position towards said closed position, said displacement of said synchronous displacement mechanism forcing each of said locking elements into said locked position,
- wherein said synchronous displacement mechanism further comprises a release mechanism mechanically linked to each of said locking elements via a unidirectional linkage such that operation of said release mechanism is effective to displace all of said plurality of locking elements from said locked position to said unlocked position, while direct displacement of one of said locking elements from said locked position to said unlocked position does not displace another of said plurality of locking elements away from said locked position.

An apparatus comprising:
- (a) an opening bounded on one side 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 said opening open and a closed position in which said panel closes at least part of said opening;
- (c) a locking element associated with said strike jamb or said panel and displaceable between a locked position in which said locking element locks the panel against opening, and an unlocked position in which said locking element allows opening of the panel;
- (d) a synchronous displacement mechanism associated with said locking element, said synchronous displacement mechanism being displaced by at least part of a closing motion of said panel from said open position towards said closed position, said displacement of said synchronous displacement mechanism forcing said locking element into said locked position,
- wherein said synchronous displacement mechanism is configured to complete displacement of said locking element to said locked position when said panel reaches a first position during said closing motion of said panel, and wherein a further motion of said panel beyond said first position forces a further motion of said synchronous displacement mechanism without further motion of said locking element.

An apparatus comprising:
- (a) an opening bounded on one side 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 said opening open and a closed position in which said panel closes at least part of said opening;
- (c) a locking element associated with said strike jamb or said panel and displaceable between a locked position in which said locking element locks the panel against opening, and an unlocked position in which said locking element allows opening of the panel;
- and
- (d) a synchronous displacement mechanism associated with said locking element, said synchronous displacement mechanism comprising:
- (i) an actuating linkage including an actuator arm, said actuating linkage being associated with said locking element for displacing said locking element between said locked position and said unlocked position, and
- (ii) a lever deployed to be displaced by relative motion of said panel and said strike jamb during said closing motion,
- wherein said lever and said actuator arm are pivotable about a common pivot axis, displacement of said lever by said closing motion causing pivotal motion of said actuator arm in a first direction so as to force said locking element into said locked position,
- said synchronous displacement mechanism further comprising a release mechanism mechanically linked to said actuator arm and actuatable so as to cause pivotal motion of said actuator arm about said common pivot axis in a second direction opposite to said first direction, thereby displacing said locking element to said unlocked position.
