Abstract

A remotely activated locking device for closure elements that is self-contained within the closure elements, electrically operated and reliable. An electric motor with a worm gear is meshed with a gear mechanism to control the movement of a locking tongue member. A gear member is caused to move between two angular positions. The gear member includes a perpendicularly mounted off-center pin. A pivotally mounted elongated arm is pushed by the offset pin to cause the retraction of a spring loaded tongue member. A receiver is also housed within the closure element to activate the motor. A remote transmitter sends a signal to activate the receiver that in turn creates an output for a predetermined amount of time when the code transmitted matches the code stored.

Claims

1. A locking device for closure elements that are hingedly mounted to a building aperture with a door latch, and comprising:

A) a housing adapted to be mounted within a closure element;

B) a spring loaded locking tongue member retractable within said closure element from a distended position protruding outwardly from said closure element into a door latch;

C) gear means for moving said locking tongue member between said retractable and distended positions including an elongated arm member having first and second ends, said first end being pivotally mounted to a cooperative point within said housing and said second end being displaced between two angular positions by said gear means, and said second end being cooperatively engaged to said locking tongue member wherein said gear means includes a gear member having an off-center pin perpendicularly mounted thereon so that said off-center pin causes the angular movement of said elongated arm member;

D) worm gear means in meshed engagement with said gear means so that movement of said gear means can only be caused by moving said worm gear means;

E) electrical motor means for rotating said worm gear means;

F) means for actuating said electrical motor means;

G) electrical means for powering said electrical motor means, and said means for actuating said electrical motor means; and

H) receiver means housed within said housing for activating said electrical means for powering said electrical motor means; and

I) transmitter means for activating said receiver means and being remotely disposed with respect to said receiver means.

2. The locking device set forth in claim 1 wherein further including switch means for limiting the angular displacement of said elongated arm member by causing the electrical power connection to said electrical motor means to be interrupted when said elongated arm member reaches a predetermined position.

3. The locking device set forth in claim 2 wherein said electrical means is housed within said housing.

4. The locking device in claim 3 further including a photocell circuit for recharging said electrical means.

5. The locking device set forth in claim 4 wherein said electrical means includes a rectifier circuit connected to an electrical source of A.C.

6. The device set forth in claim 5 further including:

J) programmable keypad means connected to said means for actuating said electrical motor means.
