Abstract

A kit for retrofitting a door with a remotely controllable locking mechanism having a combination key-operated deadbolt lock and door knob latching lock for a door. A housing for the operating parts is insertable in a mortised pocket or cavity in the latch edge of the door or it may be attached to the exterior surface of the interior well of the door. The electronics to operate the mechanism sends a signal to a receiver installable in the wall near the locks. Power is supplied to solenoids to simultaneously activate the locking and unlocking mechanisms of the deadbolt and the door knob latching lock when the kit is assembled in the door. Manual key overrides are provided for the deadbolt and for the latch.

Claims

1. A kit for retrofitting a door having an existing deadbolt lock having a bolt rotation member and door knob latching lock having a latching member comprising:

a housing;

a deadbolt operating mechanism attachable to said deadbolt lock, said deadbolt operating mechanism further comprising;

a first locking solenoid mountable within said housing;

a second unlocking solenoid mountable within said housing;

a pivoting lever attachable at a first end of said first locking solenoid, attachable at a second end to said second unlocking solenoid, and further attachable to said housing;

a bolting mechanism attachable at a first end to said first locking solenoid and adapted to be attachable to said bolt rotation member;

a direction changing member attachable at a first end to said bolting mechanism and attachable to said housing;

a latch operating mechanism attachable to said housing and further attachable at a first end to a second end of said direction changing member, said latch operating mechanism adapted to be attachable to said latching member of said latching lock;

means for mounting said housing to said door; and

a remote control unit for activating said first locking solenoid and said second unlocking solenoid to lock and unlock said deadbolt lock and said latching lock when said kit is attached thereto.

2. The kit of claim 1 wherein said bolting mechanism further comprises:

a bolt arm adapted to be attached to said bolt rotation member and a spring member attachable to a second end of said bolt arm between said bolt rotation member and said bolt arm.

3. The kit of claim 2 wherein said latch operating mechanism further comprises:

a latch pull extension attachable at a first end to a latching lever and slidingly connectable at a second end to a pull loop in a latch pull wire adapted to be attachable to said latching member of said latching lock.

4. The kit of claim 3 further comprising:

a bolt arm guide attachable to said housing; and

a latch pull arm guide attachable to said housing.

5. The kit of claim 2 further comprising:

a bolt arm wedge affixable to said housing and cooperating with said bolt arm to enable said deadbolt lock to be unlocked with a key without remote activation of said solenoids.

6. The kit of claim 1 further comprising:

a first connector extending from said bolt rotation member through a first opening in said door to rotate said bolt rotation member;

a second connector extending from said latching member through a second opening in said door to pull said latching lock; and

means for attaching said housing to an exterior surface of an interior wall of said door.

7. A kit for retrofitting a door having an existing deadbolt lock having a bolt rotation member and door knob latching lock having a latching member comprising:

a housing;

a deadbolt operating mechanism attachable to said deadbolt lock, said deadbolt operating mechanism further comprising;

a first locking solenoid mountable within said housing;

a second unlocking solenoid mountable within said housing;

a pivoting lever attachable at a first end of said first locking solenoid, attachable at a second end to said second unlocking solenoid, and further attachable to said housing;

a bolting mechanism attachable at a first end to said first locking solenoid and adapted to be attachable to said bolt rotation member;

a latch operating mechanism attachable to said housing and further attachable at a first end to a second solenoid, said latch operating mechanism adapted to be attachable to said latching member of said latching lock;

means for mounting said housing to said door; and

a remote control unit for activating said first locking solenoid and said second unlocking solenoid to lock and unlock said deadbolt lock and said latching lock when said kit is attached thereto.

8. The kit of claim 7 further comprising:

a first connector extending from said bolt rotation member through a first opening in said door to rotate said bolt rotation member;

a second connector extending from said latching member through a second opening in said door to pull said latching lock; and

means for attaching said housing to an exterior surface of an interior wall of said door.

9. A kit for retrofitting a door having a door knob latching lock having a latching member comprising:

a housing

a deadbolt lock having said bolt rotation member;

a deadbolt operating mechanism attachable to said deadbolt lock, said deadbolt operating mechanism further comprising;

a first locking solenoid mountable within said housing;

a second unlocking solenoid mountable within said housing;

a pivoting lever attachable at a first end of said first locking solenoid, attachable at a second end to said second unlocking solenoid, and further attachable to said housing;

a bolting mechanism attachable at a first end to said first locking solenoid and adapted to be attachable to said bolt rotation member,

a latch operating mechanism attachable to said housing and further attachable at a first end to a second solenoid, said latch operating mechanism adapted to be attachable to said latching member of said latching lock;

means for mounting said housing to said door; and

a remote control unit for activating said first locking solenoid and said second unlocking solenoid to lock and unlock said deadbolt lock and said latching lock when said kit is attached thereto.
