Abstract

Desk having internal power supply lines together with adjustable and/or replaceable working surfaces. A hollow beam is provided lengthwise of the desk and supported by and between appropriate, usually hollow, end members. The supply lines are brought up through, or along, the end members and into said beam which latter may be open along one side or at the top for appropriate exiting of said lines. The surface of said beam facing the user of the desk is stepped. A second beam is positioned parallel with the first beam likewise supported on the end members and has a stepped surface facing the first beam. The steps are coplanar. Thus, working surfaces comprising either hollow boxes or plates may be positioned as desired on said coplanar, usually upper, stepped surfaces and, if desired, containers as for files or other working material may be suspended from other, as lower, coplanar stepped surfaces.

Claims

1. A desk having a front and a back and two sides, comprising:

frame means comprising a pair of horiziontally spaced side members and first and second horizontally spaced wall means secured to and extending between said side members;

first stepped surface means on said first wall means facing said front of said desk and second stepped surface means on said second wall means facing said back of said desk and opposing said first stepped surface means, said first and second stepped surface means each comprising a plurality of horizontally offset, vertically spaced and upwardly facing surfaces, the lowermost surface of each of said stepped surface means being spaced closer to each other than any of the remaining surfaces, each of said upwardly facing surfaces on one of said stepped surface means being coplanar with the corresponding upwardly facing surface on the other of said stepped surface means; and

a plurality of laterally spaced support surface means each including guide means slidingly mounted on a pair of said coplanar upwardly facing surfaces and adapted to slide along the length of said upwardly facing surfaces between said side members, the width of each of said support surface means being sufficient to occupy the space between said pairs of coplanar upwardly facing surfaces but no wider or narrower than the width of the spacing between a pair of coplanar upwardly facing surfaces on which said support surface means is supported, one of said support surface means being vertically spaced from the other of said support surface means to facilitate a lateral sliding movement of said support surface means to a position vertically aligned with at least one of the other of said support surface means.

2. The desk according to claim 1, wherein said first wall means comprises an elongated hollow beam, one wall of which has said first upwardly facing surfaces formed therein.

3. The desk according to claim 2, wherein said second wall means comprises an elongated beam, one wall of which has said second upwardly facing surfaces formed therein.

4. The desk aCcording to claim 3, wherein the space between said first and second upwardly facing surfaces is open in a downward direction to facilitate the support of a downwardly depending upwardly opening container coverable by at least one of said support surface means.

5. The desk according to claim 2, wherein said elongated hollow beam includes means defining an upwardly facing opening therein for providing communication to the interior thereof and cover means for covering said upwardly facing opening.

6. The desk according to claim 5, including means defining an elongated gap between said cover means and said beam.

7. The desk according to claim 6, including electrical means mounted in said hollow beam, said electrical means comprising electrical lines which are adapted to extend through said gap means.

8. The desk according to claim 2, including electrical means mounted in said hollow beam.

9. The desk according to claim 1, wherein said guide means includes hanger means which are adapted to be supported on and extend between said first and second upwardly facing surface.

10. The desk according to claim 1, wherein at least one of said first and second wall means is located intermediate the front and back of said desk;

and including storage means mounted on the opposite side of said one of said first and second wall means from said plurality of support surface means.

11. The desk according to claim 1, wherein said first and second upwardly facing surfaces are of a monolithic construction.
