Definitions

  • the invention relates to legs adjustable in height for supporting table tops, desk tops or work tops being supported by at least two of such legs, each leg being provided with an assembly of screw shaft and nut, said shaft extending substantially in longitudinal direction of said leg, the screw shaft and nut being coupled to portions of the legs slidable relative to each other, or to a portion of said leg and the top supported by it, in such a way that on rotating the screw shaft, the leg portions can be moved relative to each other.
  • Such desk and work tops are applied on an increasingly large scale since it is desirable that a person working at a desk or the like assumes a proper sitting position. A wrong position may cause physical complaints. Furthermore, in modern offices a desk is used by various persons, so that a desk can not be adjusted to one specific person.
  • the top is supported by at least two legs, it is desirable that there is a coupling between the adjusting mechanisms of both legs. Then it can be provided for that the top remains in its horizon-tale position while adjusting it. Usually this is realized by mechanical transmissions through rotary shafts. However, such a coupling takes up a certain amount of space. This can be disturbing for e.g. legroom and cabinet space and therefore the well-known supporting structures do not have an attractive appearance and defects may arise when the height adjustment of the legs does not take place synchronously. This may occur e.g. by the fact that one leg experiences a greater load than the other, since the supported top locally holds more apparatus.
  • each leg comprises a hollow column incorporating an electric motor extending substantially in longitudinal direction, said electric motor driving a screw shaft in longitudinal direction within the column by means of a transmission, the motors of the legs being electronically coupled and electronic means being present for counting the number of rotations each of the screw shafts performs per unit of time and for mutually comparing the numbers of rotations of the screw shafts, the electronic means providing for relative adjustment of the speeds of the motors, in such a way that the number of rotations performed by each of the screw shafts per unit of time is substantially equal.
  • This electronic coupling also achieves that the legs can be arranged at any desired position, which offers a large degree of freedom in the configuration to be realized.
  • the number of rotations per unit of time of the screw shafts in the leg or legs is kept equal to the number of rotations of the screw shaft performing the smallest number of rotations.
  • the height of the top in a certain moment can be indicated on a display.
  • the user can adjust the top directly to the desired height.
  • the leg 1 illustrated in the drawing consists of a horizontally positioned transverse beam 2 being provided with supports 3 by which it can bear on the ground.
  • the beam 2 is connected to a baseplate 6 mounted in the lower end of a hollow column 5 by means of bolts 4.
  • a column 7 is telescopically slidable in the column 5.
  • the column 7 is connected to an uppermost transverse beam 8 on which a table top 9 can be mounted, which is also supported by a corresponding leg 1 not illustrated. Possibly, parts of the legs can be connected for obtaining a greater stiffness of the whole.
  • a pipe 10 being provided with a nut 11 at its upper end is mounted on the baseplate 6.
  • a screw shaft 12 extends through the nut 11 and can be driven, through a reduction gear unit 13, by an electric motor 14 fixedly mounted in the column 7.
