Door stop pin assembly
View Patent ↗Disclosed herein is a door stop pin assembly including a pin and a base pad. The pin has a concave spherical recess. And, the base pad has an open end and a closed end such that the open end has a convex spherical portion in contact with the concave spherical recess.
1. A door stop pin assembly comprising:
a pin having a concave spherical recess; and
a base pad having an open end and a closed end wherein the open end has a convex spherical portion in contact with the concave spherical recess, the convex spherical portion being fully contained and disposed in a recess within the open end of the base pad.
2. The door stop pin assembly of claim 1 wherein the contact surfaces of the concave spherical recess and the convex spherical portion are contacted without lubrication, or with a one-time light application of grease, therebetween.
3. The door stop pin assembly of claim 1 further comprising an electrically conductive path between the pin and the base pad.
4. The door stop pin assembly of claim 1 wherein the closed end of the base pad further comprises a solid lubricant, or a lubricant material in a thermosetting or thermoplastic resin system which acts as a self lubricating liner system.
5. The door stop pin assembly of claim 1 wherein the base pad further comprises an electrically conductive path between the closed end and a mating structure abutting the closed end.
6. The door stop pin assembly of claim 5 wherein base pad further comprises a ring of electrically conductive material disposed at the closed end.
7. The door stop pin assembly of claim 5 wherein the base pad further comprises a bull's-eye configuration of electrically conductive material disposed at the closed end.
8. The door stop pin assembly of claim 1 wherein the pin further comprises a threaded end.
9. The door stop pin assembly of claim 1 wherein the base pad is fabricated from a non-galling material.
10. The door stop pin assembly of claim 1 wherein the base pad is rotatable about the spherical surfaces to allow for misalignment capability between the pin and the base pad.
11. A door stop pin assembly comprising:
a threaded pin having a concave end; and,
a base pad having a complementary convex surface wherein the pin and the base pad are in electrically conductive communication with each other, the convex surface being fully contained and disposed in a recess within an open end of the base pad.
12. The door stop pin assembly of claim 11 wherein the electrically conductive communication between the pin and the base pad does not require a jumper wire to be connected between the pin and the base pad.
13. The door stop pin assembly of claim 11 wherein the concave end further comprises a concave spherical recess.
14. The door stop pin assembly of claim 13 wherein the convex surface is a convex spherical surface.
15. The door stop pin assembly of claim 14 wherein the base pad is rotatable about the spherical surfaces between the pin and the base pad.
16. The door stop pin assembly of claim 11 wherein the base pad is fabricated from a non-galling material.
17. The door stop pin assembly of claim 11 wherein the base pad further comprises an electrically conductive path between the base pad and a mating structure.
