Definitions

  • the present disclosure relates to an arrangement for vertically adjustable furniture, and especially to an arrangement for vertically adjustable furniture having an upper support part, a lower support part, two telescopic devices and a driving device for displacement of the upper support part in relation to the lower support part.
  • the invention also relates to a vertically adjustable furniture comprising such an arrangement.
  • a typical vertical adjustable furniture is a vertically adjustable table comprising an arrangement for vertical adjustment, on which upper support part a table top is arranged.
  • a vertically adjustable table typically has one leg arranged at each side of the table, in the longitudinal direction of the table.
  • W02004041027 Such a prior art arrangement is shown in W02004041027 , in which each leg has a number of telescopic tubes that are co-axial, and a power driven adjusting gear for displacement of the upper support part in relation to the lower support part.
  • the spindle of the gear is arranged inside the telescopic tubes.
  • an arrangement for vertically adjustable furniture comprising: an upper support part, a lower support part, a first telescopic device connected to the upper support part and the lower support part, the first telescopic device having a longitudinal axis extending between the upper support part and the lower support part, the first telescoping device being arranged for telescoping along its longitudinal axis.
  • the arrangement further has a second telescopic device connected to the upper support part and the lower support part, the second telescopic device having a longitudinal axis extending between the upper support part and the lower support part, the second telescoping device being arranged for telescoping along its longitudinal axis.
  • the arrangement further has a driving device for displacement of the upper support part in relation to the lower support part, the driving device having a longitudinal axis substantially parallel to the longitudinal axes of the first telescopic device and the second telescopic device.
  • the arrangement is characterized in that the longitudinal axes of each of the first telescopic device, the second telescopic device and the driving device are distanced from each other.
  • a stable arrangement is achieved, i.e. an arrangement that can withstand forces from many possible directions. Consequently, it is not necessary to have an extra stabilizer in the arrangement, such as a stable housing, for achieving such stability.
  • a leg housing surrounding the first and second telescopic device and the driving device can be formed in any way wanted, e.g. for design purposes.
  • the leg housing could be designed as a covered side, as shown in figure X.
  • an arrangement is achieved that results in a vertically displaceable furniture having fewer components than prior art displaceable furniture. I.e. a cost-efficient solution is achieved. It is also not necessary for the stability to have a cross bar connecting a first leg having such an arrangement to a second leg in a vertically adjustable furniture having such an arrangement.
  • the first telescopic device, the second telescopic device and the driving device are arranged in one plane.
  • Such an arrangement will take little space in a direction perpendicular to the plane it occupies. Thereby a user will have plenty of space below the furniture. Further, by such an arrangement the devices can be placed in one and the same housing that becomes like a vertical side of the arrangement.
  • the lower support part, the first telescoping device, the second telescoping device and the part to which the spindle nut is attached rotationally prevented constitutes a lower support unit arranged as a frame.
  • the upper support part, the outer elongated element of the first telescopic device and the outer elongated element of the second telescopic device constitutes a second frame, and wherein the first frame and the second frame is arranged such that, when the spindle is rotated by the driving means and the spindle nut moves along the spindle, the first frame moves into or out of the second frame.
  • the arrangement further comprises a second driving device for displacement of the upper support part in relation to the lower support part, the second driving device having a longitudinal axis substantially parallel to the longitudinal axes of the first telescopic device, the second telescopic device and the first driving device, wherein the longitudinal axis of the second driving device is distanced from the longitudinal axes of each of the first telescopic device, the second telescopic device and the first driving device.
  • a second driving device e.g. a second longitudinal spindle
  • extra stability is achieved.
  • the spindles are then advantageously driven by the same driving means. If an even more stable construction is needed, more than two longitudinal spindles may be arranged in parallel, between the first telescopic device and the second telescopic device.
  • the distance between the first telescopic device and the second telescopic device is at least 100 mm, preferably at least 200 mm, most preferably at least 300 mm. As the distance increases, the more stabile construction is achieved.
  • the arrangement comprises a housing that encloses the driving device, the first telescopic device and the second telescopic device.
  • a housing that encloses the driving device, the first telescopic device and the second telescopic device.
  • a vertically adjustable furniture comprising two vertical adjustment arrangements of the invention, and a connecting device, such as a table top, arranged on top of the upper support part of each arrangement, thereby connecting the two arrangements.

  • the first end is connected to the lower support part in a position distanced from a position where the first/ second telescopic device 50, 60 is connected to the upper support part 10.
