Abstract
A piece of furniture is equipped with a table top (3) which can be adjusted both in height as well as in its angle of tilt and which is suspended in a stand which consists of two hollow side pieces (1) and a hollow connecting bracket (2). Both the rear as well as the front adjusting mechanisms consist of standardized parts (29, 33, 35, 36, 39, 40) and the same parts can be used in most cases for both mechanisms. This ensures an economical manufacturing process and simplifies storage-keeping. The adjusting mechanisms can be loosely assembled for the most part without any tools, a fact that makes it possible even for unskilled workers to assemble and disassemble the device.

Piece of furniture with a stand comprising two hollow side pieces (1) and a hollow bracket (2) interconnecting the two side pieces (1), and with a table top (3) which is adjustable relative to the stand in height and/or inclination by an adjusting mechanism comprising:
- two identical spaced guide blocks (29) connected with the stand, the two blocks each having a vertical guide groove (32), the grooves facing each other, the guide groove (32) in each block (29) being undercut to both sides,
- two cogwheels (33) one each guided in a respective guide groove (32),
- an activating shaft (39,29) torsionally interconnecting the two cogwheels (33) and extending between the two blocks (29),
- a first threaded spindle (35) located in the undercut of one of the blocks (29) and meshing with the respective cogwheel (33),
- a second and a third threaded spindle (35,36) located in the undercut of the other block (29) on opposite sides of and meshing with the respective cogwheel (33), the third spindle (36) comprising means (37) for engagement by an activating crank (38), and
- two elements (40,47) rotatably mounted on the activating shaft (29,39) and connected to the table top (3).
