Definitions

  • the invention relates to a length-adjustable column according to the preamble of claim 1 and a standpipe therefor according to the preamble of the claim 4th
  • EP-B-0 366 889 is a length-adjustable column for chairs, tables or the like.
  • the base plate is supported on the end face of the edge.
  • the end face is spaced from the inner wall of the standpipe.
  • the bottom plate is to the upper end of the standpipe through a bead, indentation or the like. Held in the standpipe. This solution has been found in the Practice extremely proven.
  • the standpipe is double-walled and the about concentrically nested tube walls by means of radial webs connected and stiffened.
  • the entire standpipe is molded from plastic and can only be made in this way become.
  • At the lower end it has a ring-like bottom that is attached to the is formed on the lower end of the standpipe.
  • An axial roller bearing is supported, which in turn is supported by the piston rod of the Length adjustment element is penetrated.
  • the invention has for its object a column or a standpipe each of the generic type so that the standpipe at high strength is particularly simple in construction and particularly easy to manufacture is.
  • this object is achieved with a length-adjustable column of the generic type by the features in the labeling part of the Claim 1 and in a standpipe according to the preamble of the claim 5 solved by the features in its labeling part.
  • the chair column shown in the drawing has a standpipe 1, in which a length-adjustable gas spring 2 as a pneumatic or hydropneumatic Piston-cylinder adjusting element is arranged.
  • the standpipe 1 and the gas spring 2 have a common central longitudinal axis 3.
  • An outer housing 4 of the gas spring 2 is displaceable in the direction of the axis 3 supported in a guide bush 5, which on one - in the Drawing upper - end 6 of the standpipe 1 is arranged.
  • this outer housing 4 of the gas spring 2 can be the housing itself act or a protective tube surrounding this outside.
  • a piston rod 7 protrudes from the housing 4 of the gas spring 2 via an axial roller bearing 8 opposite a bottom 9 of the standpipe 1 in Direction of the axis 3 is supported.
  • the bottom 9 is on the one end 6 opposite the other - in the drawing below shown - end 10 of the standpipe 1.
  • a the axial roller bearing 8th penetrating pin 11 of the piston rod 7 extends through a Axis 3 concentrically formed opening 12 in the bottom 9. It is against the bottom of the bottom 9 by means of a washer 13 and one Spring retaining ring 14 secured against pulling out.
  • the diameter the opening 12 is larger than the diameter of the pin 11.
  • the standpipe 1 has an end adjacent to the end 10 slightly tapered cone section 17, by means of which a Attachment of the standpipe 1 in a corresponding conical sleeve Chair cross or the like is possible.
  • the entire base 9 of the standpipe 1 is formed in one piece with it, is therefore from the actual standpipe by deformation of the same designed.
  • the cone section 17 is adjacent to it constricted lower section 18 on which the bottom 9 is formed is. This has an open towards the inside of the standpipe 1 Channel 19, which in turn in the direction of axis 3 in ring section 20 which is substantially flat and runs radially to the axis 3 connects, which serves as a bearing surface for the axial rolling bearing 8 and the is penetrated by the opening 12.
  • the channel 19 is approximately part-circular trained and has no sharp edges.
  • the transition 21 from the groove 19 to the ring section 20 is also rounded, i.e. Not sharp-edged.
  • the inclined towards the ring portion 20 Flank 22 of the channel 19 deviates significantly from the pitch circle cross section Ring section 20 may be inclined.
  • the inner diameter D of section 18 of the standpipe 1 is like that Drawing can be seen - many times larger than the diameter d of the piston rod 7.
  • the diameter d 'of the roller bearing 8 is also significantly smaller than the inner diameter D.
  • the average width a of Channel 19 radial to axis 3 is in the range of 4 to 6 mm.
  • the inside diameter D is in the range of 30 to 50 mm.
  • the diameter d of the Piston rod 7 is in the range of 10 mm. The following applies to the diameter d ' a range of 20 to 30 mm.
  • the one that projects under the floor 9 is Area of the pin 11 with the washer 13 and the spring retaining ring 14 equally sunk in the bottom 9 because the gutter 19 protrudes downward over the ring section 20.
  • the spring circlip 14 is therefore protected within the channel 19. He can not be pulled off by high-flour carpets and the risk of injury is excluded if a user has the bottom of the foot Area of the standpipe 1 touched.
