Abstract
Various aspects of the present disclosure are directed toward apparatuses, systems, and methods that include a multipoint lock. The multipoint lock may include a horizontally translating lock bolt and at least one vertical translating lock bolt. In addition, the multipoint lock includes a linkage coupled to and configured to translate the horizontally translating lock bolt and the at least one vertical translating lock bolt. Further, the multipoint lock includes a gear mechanism configured to actuate the linkage and to effect translation of the horizontally translating lock bolt and the at least one vertical translating lock bolt.
Claims19
A multipoint lock comprising:
- a horizontally translating lock bolt;
- at least one vertical translating lock bolt;
- a linkage coupled to and configured to translate the horizontally translating lock bolt and the at least one vertical translating lock bolt;
- a gear mechanism configured to actuate the linkage and to effect translation of the horizontally translating lock bolt and the at least one vertical translating lock bolt;
- and
- an input mechanism configured to transfer rotation of the input mechanism to the gear mechanism in response to a user shifting the input mechanism between an unlocked position and an locked position.
A fenestration system comprising:
- a hinged panel;
- and
- a multipoint lock arranged within the hinged panel, the multipoint lock including:
- a first translating lock bolt,
- a second translating lock bolt,
- a linkage coupled to and configured to translate the first translating lock bolt and the second translating lock bolt,
- an elliptical gear mechanism configured to translate rotation of the gear mechanism to the linkage and actuate the first translating lock bolt and the second translating lock bolt, and
- an input mechanism configured to transfer rotation of the input mechanism to the elliptical gear mechanism in response to a user shifting the input mechanism between an unlocked position and an locked position with the elliptical gear mechanism being configured to increase force input by the user to the input mechanism progressively when transitioning from the unlocked position to the locked position.
The system of claim 11, wherein the second gear mechanism is configured to translate the horizontally translating lock bolt and effect actuation of the linkage to translate the at least one vertical translating lock bolt in response to rotation of the first gear by a user applying force to the input mechanism.
A method of operating a multipoint lock, the method comprising:
- rotating an input mechanism between an unlocked and an locked position;
- transferring rotation of the input mechanism to a gear mechanism;
- actuating a linkage in response to rotating the gear mechanism;
- and
- translating a horizontally translating lock bolt and at least one vertical translating lock bolt by actuating the linkage.
