Abstract

A door lock has a fixed housing having a thin pie shape with a hinge sleeve extending from an edge and an extension containing a hinge opening. The hinge opening connects to a hinge of a door. A rotating housing has a thin pie shape with a hinge sleeve extending from an edge and aligned with the hinge sleeve of the fixed housing. A hinge pin extends through the hinge sleeve of the fixed housing and the hinge sleeve of the rotating housing. The rotating housing has a first position that is coplanar with the fixed housing and a second position that is stacked on the fixed housing. When the rotating housing is in the first position it blocks a door from opening. Since the fixed housing is attached to the hinge of the door, the door lock is as strong as the door itself.

Claims

1. A door lock comprising:

a fixed housing having a hinge opening for mating with a door hinge;

a moveable housing; and

a hinge connecting an edge of the fixed housing to the edge of the moveable housing.

2. The door lock of claim 1, further including a set screw extending through the moveable housing.

3. The door lock of claim 1, wherein the fixed housing has a hinge sleeve that extends above a top surface of the fixed housing.

4. The door lock of claim 3, wherein the moveable housing has a hinge sleeve that extends above a top surface of the moveable housing.

5. The door lock of claim 1, wherein the moveable housing has a top surface that is in the shape of a quarter of a circle.

6. The door lock of claim 5, wherein the fixed housing has a top surface in the shape of a quarter of a circle with an extension that includes the hinge opening.

7. The door lock of claim 1, further including an alert.

8. The door lock of claim 7, wherein the alert includes an audible indicator.

9. The door lock of claim 8, wherein the alert includes a sensor.

10. A door lock comprising:

an attached planar housing having a hinge opening and a hinge sleeve on an edge of the attached planar housing;

a rotating planar housing having a hinge sleeve on an edge of the rotating planar housing; and

a hinge pin extending through the hinge sleeve of the attached planar housing and the hinge sleeve of the rotating planar housing.

11. The door lock of claim 10, further including a set screw extending through the rotating planar housing and parallel to the hinge pin.

12. The door lock of claim 10, further including an alarm system.

13. The door lock of claim 12, wherein the alarm system includes a proximity switch.

14. The door lock of claim 13, wherein the alarm system includes an indicator in communication with the proximity switch.

15. The door lock of claim 10, wherein the rotating planar housing has a first position that is coplanar with the attached planar housing and a second position where the rotating planar housing is parallel with the attached planar housing.

16. A door lock comprising:

a fixed housing having a thin pie shape with a hinge sleeve extending from an edge and an extension containing a hinge opening, wherein the hinge opening connects to a hinge of a door;

a rotating housing having a thin pie shape with a hinge sleeve extending from an edge and aligned with the hinge sleeve of the fixed housing;

a hinge pin extending through the hinge sleeve of the fixed housing and the hinge sleeve of the rotating housing;

a set screw extending through the rotating housing and parallel to the hinge pin; and

wherein the rotating housing has a first position that is coplanar with the fixed housing and a second position that is stacked on the fixed housing.

17. The door lock of claim 16, further including an alarm that indicates if the rotating housing is not in the first position.
