Security door lock with remote control
First Claim
1. A security door lock for mounting inside a wall comprising:
- means for generating a signal to activate and to deactivate said door lock;
means, connected to said signal generating means for extending a piston a predetermined distance in response to said activate signal;
means attached perpendicular to said piston for moving at least one rod said predetermined distance from a first position to a second position when activated, said rod returning to said first position when said lock receives said signal to deactivate;
means, passing through said moving means parallel to said piston, for stabilizing said moving means andsaid stabilizing means being secured between a first side and an opposite second side of said door lock.

Abstract
An electrically operated, strong, security system comprising a lock with remote control installed in a wall adjacent to a door frame. The lock comprises rods which extend into the door when the door is closed and in a locked state. In an unlocked state an actuator retracts the rods from the door, back into the door frame. The security lock system provides a manual control for the lock inside a house or building along with indicator lights showing the lock status. An emergency DC battery provides power for the security lock if there is a primary power outage. A remote control locks all doors in the house simultaneous that have such a security lock, and the remote control unlocks only the door or doors selected to be unlocked.

9. A security door lock system for mounting inside a wall adjacent to a door and a door frame comprising:
-
a remote control transmitter for generating a coded signal; receiver means for decoding said coded signal from said transmitter; means for sensing that said door is closed; means connected to said receiver means and said closed door sensing means for generating a lock control signal and an unlock control signal; actuator means connected to said lock control signal generating means for extending a piston a predetermined distance in response to said lock control signal; a rod holder bar attached approximately perpendicular to said piston for moving at least one rod said predetermined distance from a position in said door frame to a position inside said door in response to said actuator means receiving said lock signal, said at least one rod being retracted to said Position in said door frame in response to said actuator means receiving said unlock control signal; a horizontal bar passing through said rod holder bar parallel to said piston for stabilizing said rod holder bar, said horizontal bar being positioned a predetermined distance away from said attachment of said rod holder bar to said piston; and said horizontal bar being secured between a first side and an opposite second side of said lock system. - View Dependent Claims (10, 11, 12, 13)

14. A method of providing a security door lock for use in a wall adjacent to a door and a door frame comprising the steps of:
-
generating a signal to activate and a signal to deactivate said door lock; electrically extending a piston attached to an actuator toward a door in response to said activating signal, said piston being positioned in an enclosure adjacent to said door; attaching a holder bar approximately perpendicular to an end of said piston; extending at least one rod from said holder bar into a door frame; moving said rod from said door frame into said door, when said piston is extended; and stabilizing said holder bar by passing through said holder bar a horizontal bar and perpendicular thereto, said horizontal bar being securely attached at each end of said enclosure. - View Dependent Claims (15, 16, 17, 18)
