Abstract

A communication cable enclosure having a generally hollow housing, a splice area for splicing and containing cables and a patch area having multiple connectors attached to a patch panel. The multiple connectors attach to the cables at one end and are mounted to the patch panel at another end for interconnecting the cables using patch cables having matingly connectorized ends. The splice area and patch area are positioned on a generally planar top of a common shelf which has at least two side portions. The shelf is slidably retained generally parallelly co-planar the planar top. The shelf and hollow housing have locking pieces for retaining the shelf in predetermined positions along a path which it slidably travels into and out of the hollow body. The locking pieces include a locking protuberance retained on a spring portion which is fixedly retained on the hollow housing, the locking protuberance biasedly projects through a protuberance aperture formed through a side of the hollow body portion for engaging another aperture formed in the side portions of the shelf.

Claims

1. A communication cable enclosure comprising:

a generally hollow housing;

a splice area defined in said housing for splicing and containing cables;

a patch area defined in said housing and having a plurality of connectors positioned therein;

said connectors being attached to said cables at one end and having an accessible end for interconnecting said cables using patch cables having complementary connectorized ends;

said splice area and said patch area being positioned on a common shelf having a generally planar top on which said splice area and said patch area are located, said shelf having at least two opposed side portions generally perpendicularly attached to said planar top, said shelf being slidably retained within said housing;

said shelf and said housing having complementary interengagable and releasable locking means for retaining said shelf in a plurality of predetermined positions along a path which said shelf slidably travels.

2. A communication cable enclosure according to claim 1 wherein said splice area is positioned co-planar said planar top for permitting coiling of said cable in a flat orientation while maintaining generally large turn radiuses in said cable when coiled and maintaining a generally low profile of said generally hollow housing into which said shelf slides.

3. A communication cable enclosure according to claim 1 wherein a patch panel to which said plurality of connectors are mounted is positioned in said patch area, said patch panel being positioned generally perpendicular said planar top of said shelf and such that it is exposed exteriorly of said housing when said shelf is in at least one of said predetermined positions for permitting ease of access in connecting said cables positioned in said splice area to the connectors mounted to said patch panel and for connecting said patch cables between said connectors.

4. A communication cable enclosure according to claim 1 wherein said locking means comprise a protuberance receiving means formed on a portion of one of said at least two opposed side portions;

a locking protuberance mounted to sidewall portion of said housing and a protuberance aperture formed through a side of said housing through which said protuberance projects for engaging said protuberance receiving means; and

biasing means for releasably biasing said locking protuberance through said protuberance aperture and into said protuberance receiving means when said shelf is positioned along said path within said hollow so as to align said protuberance receiving means with said protuberance aperture.

5. A communication cable enclosure according to claim 4 wherein said locking protuberance comprises a shaft having a longitudinal axis extending generally coaxially with a central axis extending through the center of said protuberance aperture, and also with a central axis of said protuberance receiving means, when the latter is in registry with the aperture.

6. A communication cable enclosure according to claim 4 wherein said biasing means comprises a strip of flexible spring steel type material having a first end fixedly attached to an outer side surface of said housing and a second end attached to said locking protuberance said locking protuberance being disengagable from said protuberance receiving means by forcibly separating said second end of said biasing means from said side of said housing.

7. A communication cable enclosure according to claim 4 wherein said protuberance receiving means comprises an aperture formed through said side portion of said shelf, said aperture having dimensions generally larger than a cross-section of said locking protuberance for permitting passage of said locking protuberance when biasedly inserted therein or disengagably removed therefrom.

8. A communication cable enclosure having a generally hollow housing and a splice area for splicing and containing cables and a patch area having multiple connectors attached to a patch panel retained therein;

said multiple connectors attaching to said cables at one end and having an accessible end for interconnecting said cables using patch cables having matingly complementary connectorized ends;

said splice area and said patch area being positioned on a generally planar top of a common shelf, said shelf having at least two opposed side portions attached to said planar top, said shelf being slidably concealable in said hollow housing and slidably retained generally parallelly co-planar said planar top when extracted from said hollow housing;

said shelf and hollow housing having complementary interengagable and releasable locking means for releasably retaining said shelf in a plurality of predetermined positions along a path which said shelf slidably travels into and out of said hollow housing;

said locking means comprising a locking protuberance retained on biasing means, said biasing means fixedly retained on said hollow housing, said locking protuberance biasedly projecting through a protuberance aperture formed through a side of said hollow housing for engaging a generally conforming protuberance receiving means formed on a corresponding portion of at least one of said at least two opposed side portions.

9. A communication cable enclosure according to claim 8 wherein said enclosure has at least a pair of locking means with at least one of said locking means positioned on each of at least two opposed sides of said hollow housing, said locking protuberance of each of said at least two locking means engagable with at least two corresponding protuberance receiving apertures formed through each of said side portions of said shelf at spaced apart locations.

10. A communication cable enclosure according to claim 9 wherein said side portion have more than two protrusion receiving apertures formed therethrough and said spaced apart locations generally correspond to a closed position for disengagably lockingly retaining said shelf within said hollow housing, a patch position for disengagably lockingly retaining said shelf in a position for convenient operation within said patch area, and a splice position for disengagably lockingly retaining said shelf in a position for convenient operation within said splice area.

11. A communication cable enclosure according to claim 9 wherein said shelf is completely removable from said hollow housing.
