Flush-mounting multipoint locking system
View Patent ↗A surface-mounting multipoint lock includes an elongated housing having a lower end, an upper end, and a mounting member. The lock is configured for attachment along and external to a non-hinged vertical edge of a swinging panel along substantially a full extent of the non-hinged vertical edge. A plurality of spaced latch bolts in the housing include an upper latch bolt proximate to the upper end of the housing, and a lower latch bolt proximate to the lower end of the housing. The latch bolts are substantially laterally movable between a locked position and an unlocked position.
1. A multipoint locking system for a pair of cooperating swinging panels that includes an active panel and an inactive panel, the system comprising:
(a) an astragal configured to be externally mounted along a non-hinged vertical edge of the inactive panel, the astragal being operable to selectively fix the inactive panel in a closed position, and including at least one outwardly extending member having a plurality of spaced openings therealong; and
(b) a locking mechanism comprising:
(i) an elongated housing configured to be externally mounted along a non-hinged vertical edge of the active panel and including a channel configured to receive the outwardly extending member of the astragal;
(ii) a plurality of spaced latch bolts movably disposed in the housing, each latch bolt being movable between a locked position and an unlocked position, and being aligned with one of the spaced openings in the outwardly extending member when the outwardly extending member is received in the channel; and
(iii) at least one actuator positioned within the housing and being operable to move the latch bolts between their locked and unlocked position;
(c) wherein when the active panel and the inactive panel are closed and the latch bolts are moved to their locked positions, each of the latch bolts is received in its aligned opening in the astragal.
2. A multipoint locking system according to claim 1 wherein the latch bolts slide between their locked and unlocked positions.
3. A multipoint locking system according to claim 1 wherein the housing includes a mounting plate configured for attachment to an inside face of the non-hinged vertical edge of the active panel.
4. A multipoint locking system according to claim 1 wherein the housing is configured to substantially cover a vertical gap between the active and inactive panels.
5. A multipoint locking system according to claim 1 wherein the actuator includes at least one vertically sliding member that selectively moves the latch bolts between their locked and unlocked positions.
6. A multipoint locking system according to claim 5 wherein the actuator further includes at least one lever that selectively moves the vertically sliding member between an upper position and a lower position.
7. A multipoint locking system according to claim 1 wherein the housing includes a selectively removable cover.
8. A multipoint locking system according to claim 1 wherein the latch bolts rotate between their locked and unlocked positions.
