Abstract

A cover assembly is provided to prevent access within a mounting slot of an equipment rack. The assembly includes a cover sufficiently sized to block access to a back of the equipment rack that includes an open power source. The cover is secured to frame members by at least one hinge. The cover is configured to rotate between a closed position in which the cover blocks access to the open power source and an open position in which the cover is rotated to enable installation of a power module in the mounting slot. The assembly further includes a first spring stop lock provided the first frame member. The first spring stop lock is configured to lock the cover in the closed position and to release the cover to enable an installation of the power module within the mounting slot of the equipment rack.

First claim

What is claimed is:

1. A cover assembly for preventing access within a mounting slot of an equipment rack, the equipment rack including a chassis having an open power source located at a back of the chassis and first and second frame members that define a mounting slot configured to receive a power module in a position in which the power module engages the open power source, the assembly comprising:
a cover sufficiently sized to block access to the back of the equipment rack, the cover being secured to the frame members by at least one hinge, the cover being configured to rotate between a closed position in which the cover blocks access to the open power source and an open position in which the cover is rotated to enable installation of a power module in the mounting slot; and
a first spring stop lock provided the first frame member, the first spring stop lock being configured to lock the cover in the closed position and to release the cover to enable an installation of the power module within the mounting slot of the equipment rack.

2. The cover assembly of claim 1 , wherein the first spring stop lock is positioned within a first slot formed in the first frame member.

3. The cover assembly of claim 2 , further comprising a second spring stop lock provided in the second frame member, the second spring stop lock being configured to lock the cover in the closed position and to release the cover to enable an installation of the power module within the mounting slot of the equipment rack.

4. The cover assembly of claim 3 , wherein the second spring stop lock is positioned within a second slot formed in the second frame member.

5. The cover assembly of claim 4 , wherein each spring stop lock embodies a flat spring including a flat end that is secured to its respective frame member of the chassis of the equipment rack.

6. The cover assembly of claim 5 , wherein each spring stop lock further includes a bent portion and an inwardly bent opposite end.

7. The cover assembly of claim 6 , wherein the bent portion extends inboard within the mounting slot into the interior of the chassis with respect to its respective frame member.

8. The cover assembly of claim 6 , wherein the bent end extends perpendicularly within the interior of the chassis to maintain the cover in the closed position when a power module is not positioned within the mounting slot.

9. The cover assembly of claim 6 , wherein the spring stop lock further includes a stop to maintain the cover in the closed position and to prevent unwanted movement of the cover to the open position to access the back of the equipment rack.

10. The cover assembly of claim 1 , wherein the at least one hinge extends along a top edge of the cover beyond side edges of the cover, with opposite ends of the hinge extending through respective openings of the frame members.

11. The cover assembly of claim 1 , further comprising a spring to drive the cover to the closed position.

12. The cover assembly of claim 11 , wherein the spring is a helical torsion spring that is mounted on one end of the hinge, the spring having one end secured to the first frame member through a small opening provided in the frame member and another end that engages a surface of the cover that faces the back of the equipment rack.

13. A method of selectively blocking access to a portion of an equipment rack within a mounting slot of a chassis of the equipment rack with a cover assembly, the method comprising:
mounting a cover of the cover assembly within the mounting slot, the cover being sufficiently sized to block access to a back of the equipment rack to prevent access to an open power source, the cover being secured to first and second frame members of the chassis by at least one hinge, the cover being configured to rotate between a closed position in which the cover blocks access to the open power source and an open position in which the cover is rotated to enable installation of a power module in the mounting slot; and
selectively locking the cover in the closed position with a first spring stop lock provided the first frame member, the first spring stop lock being configured to lock the cover in the closed position and to release the cover to enable an installation of the power module within the mounting slot of the equipment rack.

14. The method of claim 13 , further comprising positioning the first spring stop lock within a first slot formed in the first frame member and positioning a second spring stop lock within a second slot formed in the second frame member.

15. The method of claim 14 , wherein each spring stop lock embodies a flat spring including a flat end that is secured to the frame member of the chassis of the equipment rack, a bent portion, and an inwardly bent opposite end, the bent portion extending inboard within the mounting slot into the interior of the chassis with respect to the frame member.

16. The method of claim 15 , wherein the bent end extends perpendicularly within the interior of the chassis to maintain the cover in the closed position when a power module is not positioned within the mounting slot.

17. The method of claim 13 , further comprising biasing a movement of the cover to the closed position with a spring.

18. An equipment rack comprising:
a chassis;
an open power source located at a back of the chassis;
first and second frame members that define a mounting slot configured to receive a power module in a position in which the power module engages the open power source; and
a cover assembly including a cover sufficiently sized to block access to the back of the equipment rack, the cover being secured to the frame members by at least one hinge, the cover being configured to rotate between a closed position in which the cover blocks access to the open power source and an open position in which the cover is rotated to enable installation of a power module in the mounting slot, and a first spring stop lock provided the first frame member, the first spring stop lock being configured to lock the cover in the closed position and to release the cover to enable an installation of the power module within the mounting slot of the equipment rack.

19. The equipment rack of claim 18 , wherein the first spring stop lock is positioned within a first slot formed in the first frame member, the equipment rack further comprising a second spring stop lock positioned within a second slot formed in the second frame member.

20. The equipment rack of claim 19 , wherein each spring stop lock embodies a flat spring having a flat end that is secured to its respective frame member of the chassis of the equipment rack, a bent portion, and an inwardly bent opposite end, the bent portion extending inboard within the mounting slot into the interior of the chassis with respect to its respective frame member.
