Abstract

A computer chassis includes a door mounted on the chassis. A hinge pivotally interconnects the door and the chassis. The hinge has a first end connected to the chassis and a second end connected to the door. A pair of spaced apart resilient receivers are provided on the chassis. A cam extension on the hinge is engaged for flexing the resilient receivers in response to pivotal movement of the hinge.

Claims

1. A computer chassis door comprising:

a chassis;

a door mounted on the chassis;

a hinge pivotally connecting the door on the chassis, the chassis including a wall having an opening therein, the hinge extending through the opening, the hinge having a first end connected to the chassis and a second end connected to the door;

a pair of spaced apart resilient receivers on the chassis; and

a cam extension on the hinge engaged for flexing the resilient receivers in response to pivotal movement of the hinge.

2. The chassis door as defined in claim 1 wherein the first end is connected internally of the chassis and the second end extends through the opening externally of the chassis.

3. The chassis door as defined in claim 2 wherein the hinge includes an axle connected to the first end.

4. The chassis door as defined in claim 3 wherein the axle is pivotally connected to the chassis.

5. The chassis door as defined in claim 1 wherein the cam extension is adjacent the first end of the hinge and extends at an angle relative to the hinge.

6. The chassis door as defined in claim 1 wherein the hinge includes a pair of U-shaped arms.

7. The chassis door as defined in claim 6 wherein the hinge includes an axle extending between each of the arms.

8. The chassis door as defined in claim 7 wherein the cam extension is adjacent the first end of the hinge.

9. The chassis door as defined in claim 8 wherein the cam extension extends at an angle relative to the hinge.

10. A computer system comprising:

a chassis;

a microprocessor mounted in the chassis;

a storage coupled to the microprocessor;

a door mounted on the chassis;

a hinge pivotally connecting the door on the chassis, the chassis including a wall having an opening therein, the hinge extending through the opening, the hinge having a first end connected to the chassis and a second end connected to the door;

a pair of resilient receivers on the chassis; and

an angled cam extension on the hinge engaged for flexing the resilient receivers in response to pivotal movement of the hinge.

11. The system as defined in claim 10 wherein the first end is connected internally of the chassis and the second end extends through the opening externally of the chassis.

12. The system as defined in claim 11 wherein the hinge includes an axle connected to the first end.

13. The system as defined in claim 12 wherein the axle is pivotally connected to the chassis.

14. The system as defined in claim 10 wherein the cam extension is adjacent to the first end of the hinge and extends at an angle relative to the hinge.

15. The system as defined in claim 10 wherein the hinge includes a pair of U-shaped arms.

16. The system as defined in claim 15 wherein the hinge includes an axle extending between each of the arms.

17. The system as defined in claim 16 wherein the cam extension is adjacent the first end of the hinge.

18. The system as defined in claim 17 wherein the cam extension extends at an angle relative to the hinge.

19. A computer door hinge comprising:

a chassis;

a door mounted on the chassis;

a hinge arm pivotally connecting the door on the chassis, the hinge arm having a first end connected within the chassis and a second end extending from the chassis and connected to the door;

the hinge including a pair of U-shaped arms and an axle extending between each of the arms;

a pair of spaced apart resilient receivers on the chassis; and

a cam extension on the hinge engaged between the resilient receivers for flexing the receivers apart in response to pivotal movement of the hinge.
