Abstract

A dampening device for use in a dampening system that operates to dampen and slow the movement of a closing door thereby reducing noise and the risk of injury, the dampening device including a piston and dampening apparatus that are moveable within a cylinder and an anchoring apparatus, the dampening device attached to various positions along a door frame or door panel.

Claims

1. A dampening system, comprising:

a door frame comprising a hinged jamb;

a door panel comprising a hinged edge, the door panel sized and shaped to engage the door frame;

at least one hinge comprising a first side of the hinge attached along the hinged jamb, and a second side of the hinge attached along the hinged edge, wherein the hinge operates to allow the door panel to move relative to the door frame; and

at least one dampener comprising a cylinder, a piston and a compressible dampening apparatus moveable within said cylinder, the at least one dampener secured within a recess of one of the hinged edge or hinged jamb such that a portion of the piston extends from the recess,

wherein the dampener operates to dampen a closing motion of the door panel about the hinge.

2. The dampening system according to claim 1, wherein the dampener further comprises an anchoring apparatus, the anchoring apparatus integrated with a portion of an outer surface of the cylinder and operating to secure the dampener within the recess.

3. The dampening system according to claim 2, wherein the anchoring apparatus comprises a plurality of spaced apart ridges, the ridges oriented unidirectionally to one another.

4. The dampening system according to claim 2, wherein the anchoring apparatus comprises a screwthread.

5. The dampening system according to claim 2, wherein the recess is a screw hole that previously held a screw of the hinge.

6. The dampening system according to claim 2, wherein the recess is a hole at a position on the hinged jamb of the door frame or the hinged edge of the door panel and located away from the hinge.

7. The dampening system according to claim 1, wherein the cylinder comprises a chamber, a closed end and an open end, and wherein the chamber is sized to receive the dampening apparatus and a portion of the piston.

8. The dampening system according to claim 7, wherein the piston comprises a piston rod, a piston head and a widened end.

9. The dampening system according to claim 8, wherein the open end further comprises an inner flange that is sized and shaped to receive and guide the piston rod and retain the widened end within the cylinder.

10. The dampening system according to claim 7, wherein the open end further comprises an outer flange operating to orient the dampener within the recess.

11. The dampening system according to claim 7, wherein the closed end is tapered and is operable to guide the dampener into the recess.

12. The dampening system according to claim 8, wherein the dampening apparatus comprises a compression spring.

13. The dampening system according to claim 8, wherein the dampening apparatus comprises a compressible material selected from one or a combination of foam, sponge, fluid, gas, silicone, latex, silicone rubber, thermoplastic elastomer and rubber.

14. The dampening system according to claim 8, wherein the dampening apparatus comprises a first magnet attached to the closed end and a second magnet attached to the widened end, wherein the first and second magnets are oriented such that like poles are facing each other.

15. The dampening system according to claim 8, wherein the cylinder further comprises one or more perforations operable to allow air to escape from the chamber.

16. The dampening system according to claim 8, wherein the piston head is in a shape selected from the group consisting of:

flat ended, rounded, angled, slanted and pointed.

17. A dampener comprising:

a cylinder comprising a chamber having an interior wall, a sealed end, a closed end and an open end;

a piston comprising a piston rod and widened end, the widened end and the piston rod moveable within said chamber such that the widened end is sized to maintain a constant contact with the wall of the chamber;

a dampening apparatus moveable within said chamber;

an anchoring apparatus integrated with a portion of an outer surface of the cylinder and operates to secure the dampener in a recess of an object; and

wherein the piston and dampening apparatus are arranged within said chamber so that the dampening apparatus is positioned between the closed end and the widened end.

18. The dampener according to claim 17, wherein the open end further comprises an inner flange having a diameter smaller than the diameter of the chamber, the inner flange sized and shaped to receive and guide the piston rod and retain the widened end within the cylinder.

19. The dampener according to claim 17, wherein the open end further comprises an outer flange operating to orient the dampener within the recess.

20. The dampener according to claim 17, wherein the closed end is tapered and is operable to guide the dampener into the recess.

21. The dampener according to claim 17, wherein the dampening apparatus comprises a compression spring, said compression spring operable to create resistance forces as the compression spring is compressed.

22. The dampener according to claim 17, wherein the dampening apparatus comprises a compressible material selected from one or a combination of foam, sponge, fluid, gas, silicone, latex, silicone rubber, thermoplastic elastomer and rubber, wherein the compressible material operates to create resistance forces as the compressible material is compressed.

23. The dampener according to claim 17, wherein the dampening apparatus comprises a first magnet attached to the sealed end and a second magnet attached to the widened end, wherein the first and second magnets are oriented such that like poles are facing each other and operate to create resistance forces as the magnets are forced towards one another.

24. The dampener according to claim 17, wherein the anchoring apparatus comprises a plurality of spaced apart ridges, the ridges oriented unidirectionally to one another.

25. The dampener according to claim 17, wherein the anchoring apparatus comprises a screwthread.

26. The dampener according to claim 17, wherein the piston head is in a shape selected from the group consisting of:

flat ended, rounded, angled, slanted and pointed.

27. The dampener according to claim 17, wherein the cylinder further comprises one or more perforations operable to allow air to escape from the chamber.

28. The dampener according to claim 17, wherein the object is a door frame or a door panel.
