Abstract

An equipment cabinet employs a rack-mountable equipment enclosure surrounded by a base, a cap, and front and rear covers. Each cover consists of a bezel and a door reversibly mounted thereon via removable hinge pins. The bezels have sidewalls that rest against ledges on the edges of the enclosure to receive support therefrom. The door has a centrally-located latch, the latch having a pawl with an eccentric catch portion that engages a latch opening on a ledge extending from the bezel. The pawl also has a tab that rests between the ends of an arcuate raised portion on the rear of the door to limit the rotational travel of the pawl. The base, cap, and covers are configured so that the enclosure is surrounded by hollows forming a peripheral passageway for cabling and the like. The base and cap have front and rear handle-like projections through which cables may be routed, and the covers have inward-facing snap tabs that engage the handle-like projections to secure the covers to the base and cap. The covers also have side access panels for inter-cabinet cabling. Clips are used to secure adjacent cabinets together; these clips attach to the handle-like projections and also pass through the access openings. Each clip is made of stamped sheet metal bent to have a C-shaped body and central spacing members. The ends of the clip have bent tips to retain the clip when installed, and the spacing members cooperate with the ends to maintain fixed separation between adjacent cabinets. The cabinet also has elongated L-shaped feet that may be installed with either an outward orientation to minimize any tendency of a single unit to tip over, or with an inward orientation to enable adjacent cabinets to be closely spaced without interference between their feet.

Claims

1. A stand for supporting an enclosure, comprising:

a base having a planar, rectangular bottom wall and two spaced-apart planar upstanding walls, said upstanding walls extending normally away from said bottom wall at opposite edges thereof, said bottom wall and upstanding walls forming a space in which said enclosure is to be received; and

two spaced-apart elongated feet each configured along only one longitudinal edge in a manner allowing the foot to be mated with said base with either an inward or an outward orientation, each foot being removably attached to said bottom wall of said base adjacent to and substantially parallel to a corresponding one of said opposite edges with either said inward or said outward orientation, each foot being sufficiently wide to extend beyond the corresponding one of said opposite edges when oriented outwardly and being sufficiently narrow to avoid interfering with the other foot when oriented inwardly.

2. A stand according to claim 1, wherein said base has a pair of spaced-apart receptacles along each of said opposite edges, and wherein each of said feet has two spaced-apart posts along said one longitudinal edge corresponding and conforming to said receptacles, the posts of said feet each being inserted in a corresponding one of said receptacles.

3. A stand according to claim 2, wherein said posts are configured to engage said receptacles such that said feet are securely retained without additional securing means.

4. A stand according to claim 2, further comprising means for securely attaching said feet to said base.

5. A stand according to claim 4, wherein said attaching means comprises:

bolts extending through said feet and said base;

lock washers disposed on said bolts; and

nuts disposed on said bolts being sufficiently tightened to lockingly secure said feet to said base.

6. A stand according to claim 1, wherein each of said feet has an L shaped cross section.

7. A stand according to claim 1, wherein said feet are made of a polycarbonate material.

8. A stand according to claim 1, wherein said feet are of substantially identical construction.

9. A stand according to claim 1, wherein said base is configured near each of said opposite edges to be secured to a similar base when sitting beside it.

10. A stand according to claim 9, wherein said base has projections extending from both ends thereof in a plane generally parallel to and closely spaced from the plane of said bottom wall, each projection being configured to receive a conforming clip used to secure said base to said similar base.

11. A stand according to claim 10, wherein each of said projections has a horizontal notch to receive said clip and a tab adjacent to said notch to catchingly secure said clip to said projection.

12. A stand according to claim 10, further comprising:

2 convex covers each attached to a corresponding end of said base, each cover having two parallel upstanding side walls, each side wall lying in substantially the same plane as a corresponding one of the upstanding walls of said base, each side wall also having an access opening located thereon adjacent to a corresponding one of said projections; and

4 removable planar access panels each attached to a corresponding one said side walls to cover the access opening thereon.

13. A support for a pair of enclosures, comprising the stand of claim 10 and a similar stand sitting adjacent thereto such that one upstanding wall thereof is adjacent to and facing one upstanding wall of the adjacent stand, the two adjacent feet from said stands having said inward orientation, and the non-adjacent feet having said outward orientation, said support further comprising a pair of clips, each clip being configured at its ends to engage the two adjacent projections at a corresponding end of said stands and being disposed thereon to maintain said stands in a predetermined spaced-apart relationship.

14. A support according to claim 13, further comprising:

4 convex covers each attached to a corresponding end of a corresponding base, each cover having two parallel up-standing side walls, each side wall lying in substantially the same plane as a corresponding one of the upstanding walls of the base attached thereto and being adjacent to a similar side wall of an adjacent cover, each side wall also having an access opening located thereon adjacent to a corresponding one of said projections, the access openings on adjacent side walls being uncovered to allow said clips to extend therethrough; and

4 removable planar access panels each attached to a corresponding one of the non-adjacent side walls of said covers to cover the access opening thereon.

15. A support according to claim 20 wherein each of the projections an said stands has a horizontal notch cradling a corresponding one of said clips and a tab adjacent to said notch, and wherein each of said clips comprises a generally C-shaped body of sheet metal having a central portion and opposing end portions of equal length, the terminal region of each end portion of each clip being spaced apart from the terminal region of the other end portion of the same clip to define an opening therebetween and being configured to have a bent tip portion extending toward the other end portion, each of said tip portion catchingly engaging the corresponding tab to retain said clip on said support, each of said clips also having two spaced apart spacing members of equal length extending from opposite edges of said central portion toward said opening being dimensioned and positioned on said central portion to cooperate with said end portions to maintain said predetermined spaced-apart relationship between said stands.

16. A support according to claim 13, wherein each of said clips comprises a generally C-shaped body of resilient material having a central portion and opposing end portions, the terminal region of each end portion being spaced apart from the terminal region of the other end portion of the same clip to define an opening therebetween and being configured to cooperate with a feature on a corresponding one of said projections so that said clip is retained thereon, the body of each clip also having at least one spacing member extending from said central portion toward said opening being dimensioned and positioned on said central portion to cooperate with said end portions to maintain said predetermined spaced-apart relationship between said stands.

17. A support according to claim 16 wherein each of said clips has exactly two of said spacing members extending from opposite edges of said central portion.

18. A support according to claim 17, wherein the end portions of each of said clips are of equal length and said spacing members of each of said clips are also of equal length.
