Abstract

A hinge device includes a fitting, a connecting arm, a cam, an elastic member, and a sleeve member. The connecting arm is pivotally connected to the fitting. The cam is located at the connecting arm. The elastic member is mounted to the fitting and includes an end portion having a non-circular cross section. The sleeve member is attached to the elastic member and is in contact with the cam. The sleeve member includes a cavity in which the end portion of the elastic member can be mounted.

First claim

The invention claimed is:

1. A hinge device, comprising:
a fitting;
a connecting arm pivotally connected to the fitting;
a cam located at the connecting arm;
an elastic member mounted to the fitting, the elastic member including an end portion having a non-circular cross section; and
a sleeve member attached to the elastic member and in contact with the cam, the sleeve member including a cavity in which the end portion of the elastic member can be mounted;
wherein the cavity of the sleeve member includes a first portion and a second portion, and the first portion has a greater diameter than the second portion.

2. The hinge device of claim 1 , further including another fitting connected to the connecting arm.

3. The hinge device of claim 1 , wherein the elastic member further includes another end portion and a coil portion, and the coil portion is connected between the end portion and said another end portion.

4. The hinge device of claim 3 , wherein the coil portion of the elastic member defines a mounting hole, and the hinge device further includes a connecting member extending through the mounting hole in order to mount the elastic member to the fitting.

5. The hinge device of claim 3 , wherein said another end portion of the elastic member is pressed against the fitting.

6. The hinge device of claim 1 , wherein the elastic member includes a portion other than the end portion and having a non-circular cross section.

7. The hinge device of claim 1 , wherein the cavity of the sleeve member is a non-circular cavity.

8. The hinge device of claim 1 , wherein the second portion has a width less than a width of the end portion of the elastic member.

9. A hinge device adapted to be mounted to a piece of furniture, the furniture including a first furniture member and a second furniture member, the hinge device comprising:
a first fitting mounted to the first furniture member;
a second fitting mounted to the second furniture member;
a connecting arm pivotally connecting the first fitting and the second fitting;
a cam located at the connecting arm;
an elastic member mounted to one of the first fitting and the second fitting, the elastic member including an end portion having a non-circular cross section; and
a sleeve member attached to the elastic member and in contact with the cam, the sleeve member including a cavity in which the end portion of the elastic member can be mounted;
wherein the cavity of the sleeve member includes a first portion and a second portion, and the first portion has a greater diameter than the second portion.

10. The hinge device of claim 9 , wherein the elastic member further includes another end portion and a coil portion, and the coil portion is connected between the end portion and said another end portion.

11. The hinge device of claim 10 , wherein the coil portion of the elastic member defines a mounting hole, and the hinge device further includes a connecting member extending through the mounting hole in order to mount the elastic member to the one of the first fitting and the second fitting.

12. The hinge device of claim 9 , wherein the elastic member includes a portion other than the end portion and having a non-circular cross section.

13. The hinge device of claim 9 , wherein the cavity of the sleeve member is a non-circular cavity.

14. The hinge device of claim 9 , wherein the second portion has a width less than a width of the end portion of the elastic member.
