Abstract

A dampening hinge for example, for furniture, having a hinge cup with a U-shaped pin, a connecting arm and a hinge base, where one end of the connecting arm is attached to the upper arm of a U-shaped pin and the other end of the connecting arm is attached to the hinge base, the lower arm of the U-shaped pin is attached to a pull rod of a damper mounted on the hinge base by means of a hinge arm module; the hinge arm module includes a swinging arm and a movable swinging arm, where the middle portion of the swinging arm is attached to the hinge base, one end of the swinging arm is hinged with the lower arm of the U-shaped pin and the other end of the swinging arm is hinged with the movable swinging arm, the movable swinging arm is further connected to the pull rod of the dampener and the hinge base, is described.

Claims

1. A dampening hinge for furniture, comprising a hinge cup, a connecting arm and a hinge base, which are hinged together in sequence, wherein, said hinge cup comprises a U-shaped pin comprising an upper arm and a lower arm, one end of said connecting arm is attached to the upper arm of said U-shaped pin and the other end of said connecting arm is attached to said hinge base by a front bottom pin, a torsion spring is mounted on said hinge base by said front bottom bin, one free end of said torsion spring bears on the upper arm of said U-shaped pin and the other free end of said torsion spring bears on said hinge base, the lower arm of said U-shaped pin is attached to a pull rod of a damper mounted on said hinge base by means of a hinge arm module, the opening and closing motion of the hinge cup relative to the hinge base is driven by an outer force, and wherein said hinge arm module comprises a swinging arm and a movable swinging arm, wherein, the middle portion of said swinging arm is attached to a pivot pin mounted on said hinge base, one end of said swinging arm is hinged with the lower arm of said U-shaped pin and the other end of said swinging arm is hinged in a swinging arm connecting hole on said movable swinging arm, a damper connecting hole provided by said movable swinging arm is used to connect said pull rod of said damper, said movable swinging arm is movably connected to a pin fixed on said hinge base by a base connecting hole thereof, said swinging arm connecting hole is positioned on one side of said base connecting hole, and said damper connecting hole is positioned on the other side of said base connecting hole.

2. The dampening hinge for furniture according to claim 1, wherein said swinging arm connecting hole, said base connecting hole and said damper connecting hole are configured in a triangle shape, in which said swinging arm connecting hole and said damper connecting hole are both above said base connecting hole.

3. The dampening hinge for furniture according to claim 1, wherein said swinging arm connecting hole, said base connecting hole and said damper connecting hole are configured in line.

4. The dampening hinge for furniture according to claim 1, wherein said base connecting hole has a shape of an ellipse.

5. The dampening hinge for furniture according to claim 2, wherein said base connecting hole has a shape of an ellipse.

6. The dampening hinge for furniture according to claim 3, wherein said base connecting hole has a shape of an ellipse.

7. The dampening hinge for furniture according to claim 1, wherein said base connecting hole is an elongated hole.

8. The dampening hinge for furniture according to claim 2, wherein said base connecting hole is an elongated hole.

9. The dampening hinge for furniture according to claim 3, wherein said base connecting hole is an elongated hole.

10. The dampening hinge for furniture according to claim 1, wherein said movable swinging arm has a U-shaped configuration and connects the swinging arm and the pull rod of the damper.

11. The damping hinge for furniture according to claim 1, wherein said damper is an air damping cylinder or a hydraulic damping cylinder.

12. A hinge comprising an operatively linked hinge cup, a connecting arm and a hinge base, further comprising:

a) a torsion spring operatively linked to said hinge cup and said hinge base, wherein said torsion spring urges closure of said hinge cup and said hinge base; and

b) a module in said hinge base, said module comprising an operatively linked swinging arm, a movable swinging arm and a dampener, wherein said module dampens said torsion spring urging.
