Abstract
Most door locks use the strength of the door jam to hold the door closed.My invention,Doorguard, is a device that connects the door to a nearby wall,or post,or flooring, and uses triangulation and compression to hold the door closed.
Doorguard allows the door to be locked,and it allows the door to be opened a small amount without being disconnected
Doorguard allows the door to be locked,and it allows the door to be opened a small amount without being disconnected
Description
SPECIFICAT~ON
The invention i-s a device for holding doors closed.
Most other locks,such as deadbolts or safety chains, connect to the doorjam and depend on it to resist hostile forces. In contrast,Doorguard uses a connection to a nearby wall or post for its' strength. The connection is such that a triangle is formed between the wall,the door, and the Doorguard. This allows any force on the door to be spread out onto the wall using triangulation and compression.
When not in use Doorguard lays flat against the wall.
When in use it locks in place with a key driven bolt.
Removal of a pin allows the door to be opened slightly, to receive mail,etc., without disconnecting the Doorguard.
The device is all metal construction.
THE FOLLOWING COMMENTS RELATE TO THE EXPANDED DRAWING.
The WALL MOUNT (1) attaches permanently to the wall with screws(or other fasteners suitable for the wall).
c-ontinued - 21~834~
It holds the Doorguard in place and spreads out any forces coming from the door onto the wall. It also has two 2 mounting brackets to attach the Pivot Block.
The PIVOT BLOCK (2) allows vertical and horizontal movement to take place.This allows the Doorguard to be put into place and removed from the door connection.
It also allows for some leeway on the initial installation.
Two RODS (3) hold the pivot block to the wall mount and to the sleeve. *One rod can be a quick release type to allow for emergency exits without the need for a key.
The SLEEVE (4) is a tube-like piece with a fitting on one end to hold a rod. It is hollow to accept the Arm,and allows the arm to slide back and forth a limited amount.
On its' top and bottom are holes that accept the Pin.
The PIN (5) is a solid piece with a90 bend in its' length.
Removing it from the sleeve allows the Arm to move in.
The ARM (6) is a tube that fits into the Sleeve. The end opposite to the sleeve has a fitting perpendicular to the length of the Arm. This fitting is captured by the lock assembly. -^
The LOCK ASSEMBLY (7) is a casting that holds the pieces of the lock,and also has screw holes that allow it to be fixed to a door.
The KEY LOCK (8) raises and lowers the bolt into place and holds it in position.It is a vendor supplied part.
The BRACKET (9) gives the lock the necessary range of continued The BRACKET (9) gives the lock mechanism the necessary 3 range of motion. A pin on the bracket engages a slot in the Bolt Plate.
The BOLT PLATE (10) consists of a flat plate with a slot and a round bolt. When the key is turned the Bolt Plate is raised and the bolt fits into a cavity near the top of the Lock Assembly. When the Arm(6) is in place it is captured by the bolt,but the arm can still move axially to allow the door to be opened slightly.

Claims (4)
1. A device to hold a door closed against an outside force using triangulation to control the force.
2. A device as claimed in claim 1 in which a lock with vertical bolt secures it against removal.
3.A device as claimed in claim 1 or 2 in which a pivot allows a free range of motion to allow ease of usage and assembly.
4.A device as claimed in claim 1,2,or 3 that has an adjustment that allows the door to be opened slightly without the unlocking of the locking device.
