Abstract

A keyless remote control door unlatching, unlocking and opening system comprising a remote transmitter to send a signal to actuate a pair of solenoids located in a door jamb opposite the latch bolt and the dead bolt. The push rods of the solenoids force the dead bolt and the latch bolt out of the strike plates and immediately retract. Contact with the angled contact surface of the latch bolt causes the door to pivot open.

Claims

a door pivotally mounted within a door jamb, said door jamb having a latch strike plate and a bolt strike plate disposed thereon;

a door latching mechanism comprising a spring biased latch bolt having a non-perpendicular contact surface, whereby said latch bolt is forced into a recessed position within said door when said contact surface abuts said latch strike plate when said door is pivoted closed, and further whereby said latch bolt automatically extends into an opening of said latch strike plate when said door is fully closed;

a dead bolt locking mechanism comprising a dead bolt, said dead bolt being extendable into said bolt strike plate when said door is fully closed, whereby said dead bolt is movable into a recessed position by pressing against said dead bolt;

a pair of solenoids disposed within said door jamb, each of said solenoids comprising a push rod that extends through said one of said latch strike plates when said solenoid is activated and a retracting spring, whereby said push rod is retracted by said retracting spring when said push rod reaches maximum extension; and

operative control means to actuate said solenoids, said operative control means comprising a remote transmitter and receiver/controller means to receive a signal from said transmitter and to operate said solenoids;

such that upon actuation of said solenoids, one of said push rods forces said dead bolt into the recessed position within said door and the other of said push rods forces said latch bolt into the recessed position within said door, whereby contact between said push rod and said non-perpendicular contact surface of said latch bolt initiates pivoting movement of said door out of said closed position.

2. The system of claim 1, wherein less than 7 pounds of pressure is required to force said dead bolt into the recessed position within said door.

3. The system of claim 2, wherein approximately 2 pounds of pressure is required to force said dead bolt into the recessed position within said door.

4. The system of claim 2, wherein said dead bolt locking mechanism comprises a trigger member, and wherein said trigger member is rounded such that less than 7 pounds of pressure is required to force said dead bolt into the recessed position within said door.

5. The system of claim 3, wherein said dead bolt locking mechanism comprises a trigger member, and wherein said trigger member is rounded such that approximately 2 pounds of pressure is required to force said dead bolt into the recessed position within said door.

6. The system of claim 1, further comprising a seal member disposed on said door jamb, said seal member contacting and compressed by said door when said door is in the closed position, whereby said seal member also initiates pivoting movement of said door out of said closed position.

7. The system of claim 1, further comprising secondary initiator means mounted to said door jamb, said secondary initiator means comprising a ram member and a spring such that said spring is compressed when said door is in the closed position, whereby said secondary initiator means also initiates pivoting movement of said door out of said closed position.
