Abstract

A furniture assembly includes a base, a pair of lifting columns flanking the base, a mounting panel fixed to the lifting columns in front of the base so that it can be raised and lowered, and a flat electronic display screen fixed to the mounting panel. According to a preferred embodiment, the furniture assembly is a modular assembly and includes a top module detachably fixed to a base module. The mounting panel can be moved between an upper position, where it at least partially covers the top module, and a lower position, where it at least partially covers the base module. The assembly includes a wiring harness fixed to the back of the screen for inputting video signals to the display screen from a number of electronic sources such as a TV antenna, a VCR, a DVD player, and a computer. The harness is movable through a space between the front and the rear of the base under the action of a retracting mechanism which keeps the harness taut as the panel is raised and lowered.

Claims

1. A furniture assembly comprising:

a base having a front, a rear, and a pair of opposed sides;

a pair of lifting mechanisms arranged adjacent to respective said sides, each said lifting mechanism comprising means for vertically raising and lowering an article fixed thereto;

a mounting panel arranged adjacent to the front of said base and fixed to said lifting mechanisms so that said mounting panel can be vertically raised and lowered by said lifting mechanisms;

a flat electronic display screen fixed to said mounting panel; and

at least one wire coupled to said display screen for inputting electronic video signals,

wherein said base is configured as a base module, said assembly further comprising at least one end module which can be detachably fixed to a respective at least one of said sides of said base module with a respective at least one of said lifting mechanisms between said at least one end module and said base module.

2. A furniture assembly as in claim 1 wherein said mounting panel can be vertically raised and lowered between an upper position and a lower position, said mounting panel at least partially covering said base in said lower position.

3. A furniture assembly as in claim 2 further comprising a top section situated above said base, said mounting panel at least partially covering said top section in said upper position.

4. A furniture assembly as in claim 3 wherein said base is formed as a base module and said top section is formed as a top module which is detachably fixed to said base module.

5. A furniture assembly as in claim 1 wherein said base is formed as a base module, said assembly further comprising a top module which is detachably fixed to said base module above said base module.

6. A furniture assembly as in claim 1 wherein each said module comprises at least one of at least one drawer, at least one cabinet, and at least one shelf.

7. A furniture assembly as in claim 1 wherein said base comprises a computer work station.

8. A furniture assembly as in claim 1 wherein said base is profiled to fit in the corner of a room with one of said lifting columns adjacent to each of two walls of the room, whereby said mounting panel extends between said walls.

9. A furniture assembly as in claim 1 further comprising a space through which said at least one wire extends between the front and the rear of said base.

10. A furniture assembly as in claim 9 further comprising means for moving said at least one wire through said space so that said harness remains substantially taut between said rear of said base and said mounting panel as said mounting panel is raised and lowered.

11. A furniture assembly as claim 10 wherein said means for moving said at least one wire through said space comprises means for retracting said at least one wire so that any slack in said at least one wire accumulates at the rear of said base.

12. A furniture assembly as in claim 11 wherein said means for retracting said at least one wire comprises at least one elastic tether having one end fixed to said at least one wire and another end fixed to said base.

13. A furniture assembly as in claim 10 wherein said at least one wire moves from said rear to said front as said panel is lowered, and from said front to said rear as said panel is raised.

14. A furniture assembly as in claim 10 wherein said at least one wire comprises a plurality of wires connected to a plurality of connectors on the rear of said base, each said connector providing an electronic signal input from a different source of video signals.

15. A furniture assembly as in claim 1 wherein each said lifting mechanism comprises a lifting column located toward the front of said base, each said lifting column comprising a vertically movable block to which said mounting panel is fixed.

16. A furniture assembly as in claim 15 wherein each said lifting column comprises a housing, a motor driven threaded shaft in said housing, and a slot in said housing which parallels said shaft, each said block engaging said threaded shaft in said housing so that said blocks are raised and lowered synchronously as said shafts are driven to rotate.

17. An apparatus for positioning a flat electronic display screen, comprising:

a furniture piece having a front facing into a room, and a rear;

motive means for moving the flat electronic display screen vertically in a plane adjacent to the front of said furniture piece;

powered drive means for driving said motive means;

drive control means for actuating said powered drive means to move said flat electronic display screen to a desired position in said plane; and

a sensor for detecting when said flat electronic display screen is turned OFF to generate an output signal;

wherein said drive control means responds to said output signal when said screen is turned OFF to move said screen to a predetermined position, and

a safety detector including means for inhibiting motion of said screen in said plane when the detector is activated by a person touching a portion of said motive means.

18. An apparatus as in claim 17, wherein said predetermined position is an uppermost position in said plane.

19. A furniture assembly comprising:

a base having a front, a rear, and a pair of opposed sides;

a pair of lifting mechanisms arranged adjacent to respective said sides, each said lifting mechanism comprising means for vertically raising and lowering an article fixed thereto;

a mounting panel arranged adjacent to the front of said base and fixed to said lifting mechanisms so that said mounting panel can be vertically raised and lowered by said lifting mechanisms;

a flat electronic display screen fixed to said mounting panel;

at least one wire coupled to said display screen for inputting electronic video signals,

a space through which said at least one wire extends between the front and the rear of said base, and

means for moving said at least one wire through said space so that said harness remains substantially taut between said rear of said base and said mounting panel as said mounting panel is raised and lowered.

20. A furniture assembly as claim 19 wherein said means for moving said at least one wire through said space comprises means for retracting said at least one wire so that any slack in said at least one wire accumulates at the rear of said base.

21. A furniture assembly as in claim 20 wherein said means for retracting said at least one wire comprises at least one elastic tether having one end fixed to said at least one wire and another end fixed to said base.

22. A furniture assembly as in claim 19 wherein said at least one wire comprises a plurality of wires connected to a plurality of connectors on the rear of said base, each said connector providing an electronic signal input from a different source of video signals.
