Multiple point door locking system

摘要

A multi-function door lock system, comprising in combination, a frame having opposite sides, and installable on a door openable between an interior space and an exterior space, a deadbolt and a door latch carried by the frame to move between retracted and extended positions, a first rotary control located at one level on the frame to control deadbolt movement between extended and retracted positions via primary cam mechanism, a second rotary control at another level on the frame to control latch movement between extended and retracted positions, via secondary cam mechanism, means operatively connected between said secondary cam mechanism and the primary cam mechanism to effect deadbolt movement as aforesaid, in response to operation of the second rotary control, as effected via rotary input to the second rotary control from only one side of the frame. Means is also provided to be responsive to reverse rotation of the first rotary control to effect latch retraction independently of deadbolt displacement.

主权项

1. A door lock system, comprising:
a) a frame having a first side and a second side opposite said first side; b) a deadbolt and a door latch connected to said frame and configured to move between retracted and extended positions; c) a first rotary control connected to said frame, said first rotary control having a first axis of rotation and configured to control deadbolt movement between extended and retracted positions and to retract said deadbolt when said first rotary control is rotated in a first rotational direction; d) a second rotary control having a second axis of rotation off-spaced from said first rotary control and configured to control latch movement between extended and retracted positions; and e) a lever coupled to said frame at a pivot point, wherein said lever includes an extension configured to positively move said latch to said retracted position in response to rotation of said first rotary control in said first rotational direction when said deadbolt is moved toward said retracted position by said first rotary control, wherein said lever is configured to be rotatable about said pivot point in a second rotational direction opposite of said first rotational direction through an arc in response to a rotary input to said first rotary control, and wherein said lever effects simultaneous movement of said deadbolt and said latch between said extended and retracted positions in response to said rotary input to said first rotary control.
