US 6,629,713 B1 · Dead bolt lock assembly for sliding doors and/or windows

Abstract

A dead bolt lock assembly for securing a sliding door or window and including a wall mountable dead bolt lock, and a door mountable dead bolt lock which matingly engage in the locked position to secure the sliding door or window shut, is disclosed. The wall mountable dead bolt lock may be moved between an unlocked position and a locked position (where it is received within the housing of the door mounted dead bolt) in an automatic manner by an actuator which is preferably normally biased to extend slightly beyond the door jamb. The actuator may be connected to the dead bolt by a drive assembly which is activated upon movement of the actuator inwardly toward the door jamb, for example by a plunger. In one embodiment, as the actuator moves inwardly, it causes the dead bolt to move outwardly, until it is received within the housing of the door mounted dead bolt. The wall mounted dead bolt includes an aperture at one end for receiving the dead bolt of the door mounted dead bolt therein. The sliding door is locked when the door mounted dead bolt is moved into the aperture of the wall mounted dead bolt.

Dependent claims

The dead bolt lock assembly for use with a slidable door or window having at least one slidable panel, comprising:

a wall mountable dead bolt lock including a housing constructed and arranged to be installed within a wall stud;
a first dead bolt having a first end supported within the housing and adapted to move reciprocally into and out of the housing along a first axis and having a second end including an aperture formed therein;
a door mountable dead bolt lock including a housing-constructed and arranged to be installed within a frame of the slidable panels the housing including an opening constructed and arranged to receive the first dead bolt in a locked position and supporting a second dead bolt therein, the second dead bolt being movable between a first, unlocked position spaced from the first dead bolt and a second locked position in which the second dead bolt is at least partially received within the aperture of the first dead bolt;
an actuator operatively connected to the first dead bolt, wherein movement of the actuator in a first direction causes the first dead bolt to move in a second direction, opposite the first direction of the actuator;
and
wherein upon moving the second dead bolt into the aperture of the first dead bolt the sliding panel is secured in a closed position.

3 more elements

A method of securely locking a slidable panel closed, comprising the steps of:

mounting a dead bolt lock including a housing within a wall stud, the wall mounted dead bolt lock including a first dead bolt having a first end supported within the housing and adapted to move reciprocally into and out of the housing along a first axis, and having a second end including an aperture formed therein;
providing a dead bolt lock including a housing within a frame of the slidable panel, such that an opening in the housing is positioned to receive the first dead bolt in a locked position, the door mounted dead bolt lock further including a second dead bolt supported therein, the second dead bolt being movable between a first, unlocked position spaced from the first dead bolt and a second, locked position in which the second dead bolt is received within the aperture of the first dead bolt;
