Abstract: A multipoint lock including a pivoting lock bolt including a fixed pivot point and a sliding pivot point, a translating lock bolt, a linkage coupled to and configured to pivot the pivoting lock bolt and to translate the translating lock bolt, an actuation mechanism configured to actuate the linkage and to effect pivoting of the pivoting lock bolt and translation of the translating lock bolt, and an input mechanism configured to receive user input and transmit the user input to the actuation mechanism, the user unput including shifting the input mechanism between an unlocked position and a locked position.

Abstract: A panel installation assist device for supporting one end of a panel during installation includes a bar, which has a set of holes extending therethrough from a first face thereof. Respective holes are selectively alignable with studs or rafters. Mounting hardware inserted through the holes mounts the bar to the studs or the rafters. The bar has a set of orifices positioned therethrough, each of which has a spirit bubble tube positioned therein, which is engaged to the bar. Respective spirit bubble tubes indicate an orientation of a longitudinal axis of the bar relative to horizontal and vertical. A notch extends into the bar from a first edge thereof and the first face, and between opposed ends of the bar. The notch is configured for insertion of an edge of a panel so that one end of the panel is supported by the bar to facilitate installation of the panel.

Abstract: An electronic lock with power failure control circuit includes a lock mechanism having a latchbolt movable between extended and retracted positions and an electrically powered lock actuator to lock and unlock the latchbolt. The power failure control circuit includes a microcontroller and the lock is connected to a primary power source and an auxiliary power source, preferably supercapacitors and charger that can be turned on by the microcontroller and off when the charger signals a full charge. A power monitor circuit detects low voltage on the primary power supply and sets a power failure interrupt causing the microcontroller to execute power failure instructions that control the actuator so that the lock is placed into a desired locked or unlocked final state during the power failure. Upon detection of the return of good power, the system resets the lock.
