Abstract

A safety apparatus for a door is disclosed, the safety apparatus comprising a first member mounted to a door frame and a second member communicating within the first member in response to an outwardly biased spring. A guide is formed on a wall of the first member. A dowel pin projects from the second member, wherein the dowel pin communicates with the guide. The guide has at least a first pathway receiving the dowel pin to allow the door to close. The spring has torque along the length of the spring for urging movement of the dowel pin within the first pathway so that the door may close.

Claims

1. A safety apparatus for a door comprising:

a first member mounted to a door frame and a second member communicating within the first member in response to an outwardly biased spring;

a guide formed on a wall of the first member;

a dowel pin projecting from the second member, the dowel pin communicating with the guide;

the guide having at least a first pathway receiving the dowel pin to permit the door to close; and

the spring having torque along the length of the spring for urging movement of the pin within the first pathway so that the door may close.

2. The apparatus of claim 1, wherein the first member has a flange for mounting the first member to the door frame.

3. The apparatus of claim 1, wherein the first member has a hole for receiving one end of the spring.

4. The apparatus of claim 1, wherein the second member has a hole for receiving one end of the spring.

5. The apparatus of claim 1, wherein the second member has a face that engages the door when urged toward the safety apparatus.

6. The apparatus of claim 1, wherein an end of the spring is coupled to the first member and an opposing end of the spring coupled to the second member, the coupling of the spring is oriented so that torque is generated and stored until the door engages the second member, and the momentum and force of the door is not sufficient to overcome the torque and the spring urges the dowel pin into the first pathway and permits closure of the door.

7. The apparatus of claim 6, wherein the momentum and force of the door is sufficient to overcome the torque and the spring urges the dowel pin away from the first pathway and inhibits closure of the door.

8. A safety apparatus for a door comprising:

a first member having a recess and a guide formed in a wall of the first member, the first member mounted to a door frame;

a second member communicating with the recess in response to an outwardly biased spring housed in the recess and coupled to the first member and the second member;

a dowel pin projecting from a wall of the second member, the dowel pin communicating with the guide;

the guide having at least a first pathway and a second pathway, the first pathway receiving the dowel pin to allow the door to close, and the second pathway receiving the dowel pin to inhibit the door from closing; and

the spring coupled to a closed end of the first member and a closed end of the second member communicating with the recess, the spring having torque along the length of the spring for urging movement of the pin within the first pathway so that the door may close.

9. The apparatus of claim 8, wherein the first member has a flange for mounting the first member to the door frame.

10. The apparatus of claim 8, wherein the second member has a face that engages the door when urged toward the safety apparatus.

11. The apparatus of claim 8, wherein the coupling of the spring is oriented so that torque is generated and stored until the door engages the second member, and whereby the momentum and force of the door is not sufficient to overcome the torque and the spring urges the dowel pin into the first pathway and permits closure of the door.

12. The apparatus of claim 11, wherein the momentum and force of the door is sufficient to overcome the torque and the spring urges the dowel pin into the second pathway and inhibits closure of the door.

13. The apparatus of claim 8, wherein the dowel pin has a tear-shape cross section.

14. A safety apparatus for a door comprising:

a first member having at least one wall upstanding from an enclosed end defining a recess, the first member having a guide formed in the at least one wall, the first member mounted to a door frame;

a second member having at least one wall upstanding from enclosed and opposing ends, the second member placed within the recess of the first member, the second member reciprocating within the recess in response to an outwardly biased spring housed in the recess and coupled to the first member and the second member;

a dowel pin projecting from the at least one wall of the second member, the dowel pin communicating with the guide;

the guide having three pathways, the first pathway receiving the dowel pin to allow the door to close, the second pathway receiving the dowel pin to inhibit the door from closing, and the third pathway receiving the dowel pin to release the dowel pin from the guide for removing the second member from the first member; and

the spring coupled to the closed end of the first member and the closed end of the second member communicating with the recess, the spring positioned having torque along the length of the spring, wherein the torque urges movement of the pin within the first pathway so that the door may close.

15. The apparatus of claim 14, wherein the first member has a flange for mounting the first member to the door frame.

16. The apparatus of claim 14, wherein the second member has a face that engages the door when urged toward the safety apparatus.

17. The apparatus of claim 14, wherein the face has a strike plate.

18. The apparatus of claim 14, wherein the dowel pin has a tear-shape cross section.

19. The apparatus of claim 14, wherein the coupling of the spring is oriented so that torque is generated and stored until the door engages the second member, and whereby the momentum and force of the door is not sufficient to overcome the torque and the spring urges the dowel pin into the first pathway and permits closure of the door.

20. The apparatus of claim 14, wherein the momentum and force of the door is sufficient to overcome the torque and the spring urges the dowel pin into the second pathway and inhibits closure of the door.
