Remote control door lock system
First Claim
1. A wireless remote controlled lock system for a pedestrian door for a residential or commercial building wherein said door includes a door jamb adapted to support a striker plate co-operable with said door for latching said door in a closed and locked position, said lock system comprising:
- a striker assembly adapted to mount on said jamb and including a striker plate member moveable between a first position to allow said door to open and a second position for locking said door in a closed position;
a control unit including a wireless signal receiver and circuit means for causing said striker assembly to move said striker plate member to said first position at least momentarily;
a wireless transmitter operable to transmit a signal to said receiver to effect operation of said striker plate to move between said first and second positions;
said circuit means includes circuit elements operable upon receiving a first signal by said receiver from said transmitter to cause said striker assembly to move said striker plate member to said first position and upon receiving a second signal from said transmitter by said receiver to cause said striker plate member to move to said second position; and
said circuit elements include a first relay operably connected to a source of electrical power and said striker assembly and responsive to a first signal from said receiver to energize said striker assembly to move said striker plate member to said first position and said first relay includes a latching contactor operably connected to said circuit means for holding said first relay in a latched position to energize said striker assembly.

Abstract
A wireless remote control lock system for residential and commercial building pedestrian doors includes an electrically powered striker plate assembly having a striker plate member moveable between positions for engagement and disengagement with a door latch member. The striker assembly is adapted to be connected to a control unit which supplies low voltage DC power to the striker assembly and includes a radio frequency range signal receiver and a circuit responsive to receiving signals from an operator controlled radio transmitter to effect indefinite or momentary operation of the striker assembly to unlock a door. The control unit circuit includes a first self-latching relay, a selector switch and a second relay for selecting an operating mode of the system wherein the door may be unlatched momentarily (for about 3.5 seconds, for example) or indefinitely until a second signal is transmitted by the transmitter to the receiver.

10. A remote control lock system for providing wireless remote control of locking and unlocking a pedestrian door in a residential or commercial building, said lock system including:
-
an electrically powered striker plate assembly, said striker plate assembly including a moveable striker plate member operable to be engageable with a door latch member, said striker plate member being operable in response to a low voltage DC electrical signal to move from a door latching position to a door unlatching position; a control unit including conductor means adapted to be connected to said striker plate assembly, said control unit including a wireless signal receiver, connector means for connecting said control unit to a source of AC electrical power and rectifier means for converting said AC power to low voltage DC power, said control unit further including a circuit operably connected to said receiver and to said striker assembly and responsive to predetermined signals transmitted to said receiver to cause said striker assembly to effect unlatching a door indefinitely or momentarily; a wireless transmitter operable to transmit a signal to said receiver to effect one of said indefinite or said momentary unlatching of said door; and a mode selector switch connected to said circuit and operable in a first position to cause said circuit to operate said striker assembly to effect unlatching said door indefinitely in response to a signal transmitted to said receiver, said mode selector switch being operable in a second position to cause said circuit to operate said striker assembly to unlatch said door momentarily in response to a signal transmitted to said receiver. - View Dependent Claims (11, 12, 13, 14, 15)

16. A wireless remote controlled door lock system for a doorway for a residential or commercial building wherein said doorway includes a door jamb for supporting a striker plate assembly co-operable with a door for latching said door in a closed position, said lock system comprising:
-
a striker assembly adapted to mount in a recess in said door jamb and including a striker plate member moveable between a first position to allow said door to open without actuating a latch bolt of said door and a second position for locking said door in a closed position; control means including a wireless signal receiver operably connected to a circuit for causing said striker assembly to move said striker plate member to said first position at least momentarily; a wireless transmitter operable to transmit signals to said receiver to effect operation of said striker plate member to move between said first and second positions; a first relay in said circuit operably connected to a source of electrical power and said striker assembly and responsive to a signal from said transmitter to said receiver to energize said striker assembly to move said striker plate member to said first position, said first relay including a latching contactor operably connected to said circuit for holding said first relay in a latched position to energize said striker assembly; and a second relay in said circuit and operably connected to said first relay and to said receiver, said second relay being responsive to a signal from said transmitter to said receiver to effect unlatching of said first relay for operation to de-energize said striker assembly. - View Dependent Claims (17, 18, 19)
