  • corresponding support bearings 12 are provided on a non-toothed inner circumference of the toothed ring.
  • a plurality of operating handles B are provided on the toothed ring, by hand can be taken to cause a corresponding rotational movement on the control means 5a.
  • FIGS. 6 to 8 A further embodiment, which is illustrated in FIGS. 6 to 8, is substantially similar to the embodiment shown in FIGS. 3 to 5.
  • a table top 1c is carried by four identical support columns 13c telescopically extendable to change the vertical position of the table top 1c.
  • a screen 25 is provided on the outer edges of the table top 1c.
  • the change in position is accomplished by turning a control means 5c in the form of a toothed ring or by moving actuating handles B fastened to the toothed ring.
  • the toothed ring meshes with pinions 26 of the four support columns 1c.
  • the toothed ring is guided by support bearings 12c, each support column 13c being associated with such a support bearing 12c.

  • the support bearing 12c are not directly connected to the table top 1c, but each rotatably mounted on a fixed to the table top 1c fitting 27, which also serves to support the pinion 26 of the respective support columns 13c. This ensures that the distance between the support rollers and the pinions 26 of the support columns 13c is respectively precisely and permanently fixed, whereby a particularly reliable and low-noise combing of the toothed ring with the pinions 26 is possible.
  • the support columns 13c differ significantly in their construction from those of the embodiment of Figures 3 to 5. They in turn include in each case a base tube 3c and a support tube 2c displaceable therefor.

  • a rotary operation of the ring gear leads to a rotational movement of the pinion 26 with their respective threaded spindles 6c. Since rotation of the nuts 7c prevents rotation of the nuts 7c relative to the respective support tube 2c, rotation of the threaded spindles 6c results in axial displacement of the support tubes 2c relative to the pedestal tubes 3c. A raising or lowering of the table top 1c is the result.
