Abstract

A hinge includes a first connector, a casing, a bush and a second connector. The first connector includes a post and a beam extended from the post. The post can be connected to a portion of a laptop computer. The casing is non-rotationally mounted on the beam. The bush is disposed non-rotationally in the casing. The second connector includes a shaft and a plate extended from the shaft. The shaft is rotationally inserted in the bush. The plate can be connected to another portion of the laptop computer.

Claims

1. A hinge comprising:

a first connector comprising a post for connection to a portion of a laptop computer and a beam extended from the post;

a casing non-rotationally mounted on the beam;

a bush non-rotationally disposed in the casing; and

a second connector comprising a shaft rotationally inserted in the bush and a plate extended from the shaft for connection to another portion of the laptop computer.

2. The hinge according to claim 1 wherein the first connector comprises a connective device on the beam, and the casing comprises a connective device connected to the connective device of the first connector.

3. The hinge according to claim 2 wherein the connective device of the first connector comprises a wall, and the connective device of the casing comprises at least one wall connected to the wall of the connective device of the first connector.

4. The hinge according to claim 3 wherein the connective device of the casing comprises two walls for sandwiching the wall of the connective device of the first connector.

5. The hinge according to claim 3 comprising at least one fastener for connecting the wall of the connective device of the first connector to the wall of the connective device of the casing.

6. The hinge according to claim 5 wherein the fastener is a rivet.

7. The hinge according to claim 6 wherein the wall of the connective device of the first connector defines an aperture for receiving the rivet, and the wall of the connective device of the casing defines an aperture for receiving the rivet.

8. The hinge according to claim 1 wherein the casing defines a space and a groove in communication with the space, and the bush comprises a sleeve inserted in the space and a positioning device inserted in the groove.

9. The hinge according to claim 8 wherein the positioning device comprises at least one pair of parallel tabs.

10. The hinge according to claim 8 wherein the positioning device comprises at least one pair of diverged tabs.

11. The hinge according to claim 8 wherein the positioning device comprises at least one pair of parallel tabs and at least one pair of diverged tabs.

12. The hinge according to claim 8 wherein the sleeve comprises a polygonal from when it is viewed in a longitudinal direction.

13. The hinge according to claim 12 wherein the sleeve comprises rounded corners in contact with an internal side of the casing.

14. The hinge according to claim 1 wherein the shaft defines at least one annular groove for containing damping oil.

15. The hinge according to claim 14 wherein the shaft defines two annular grooves.
