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 claim 5.
  • Such length-adjustable columns are known from EP 0 366 889 B1 (corresponding to US Pat. No. 4,969,619).
  • the lower edge of the standpipe is bent approximately in a semicircular cross-section to form a channel which is open in the direction of the central longitudinal axis and into the standpipe.
  • 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 towards the upper end of the standpipe through a bead, indentation or the like. held in the standpipe.
  • the invention has for its object to design a column or a standpipe of the generic type so that the standpipe high strength is particularly simple and is particularly easy to manufacture.
  • the measures according to the invention a separate base plate, or the like in a further separate operation by means of a bead. to be determined is completely saved.
  • the stability of the floor design is extremely high, so that even if the standpipe in the area of the floor is large compared to the piston rod or a bearing to be attached to it, the piston rod of the length adjustment element is reliably held.
  • the chair column shown in the drawing has a standpipe 1, in which a length-adjustable gas spring 2 is arranged as a pneumatic or hydropneumatic piston-cylinder adjusting element.
  • 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 displaceably supported in the direction of the axis 3 in a guide bush 5, which is arranged at one end 6 of the standpipe 1, which is upper in the drawing.
  • this outer housing 4 of the gas spring 2 can be the housing itself or a protective tube surrounding it.
  • a piston rod 7 protrudes from the housing 4 of the gas spring 2 and is supported via an axial roller bearing 8 in relation to a base 9 of the standpipe 1 in the direction of the axis 3.
  • the bottom 9 is located at the one end 6 opposite the other end 10 of the standpipe 1, shown in the drawing below.
  • a pin 11 of the piston rod 7 passing through the axial roller bearing 8 extends through an opening 12 in the opening 3 which is concentric with the axis 3 Bottom 9. It is secured against being pulled out against the underside of the bottom 9 by means of a washer 13 and a spring retaining ring 14.
  • the diameter of the opening 12 is larger than the diameter of the pin 11.
  • the standpipe 1 has, adjacent to the end 10, a slightly conical tapered section 17, by means of which the standpipe 1 is fastened in a corresponding cone bushing of a chair cross or the like. is possible.
  • the entire base 9 of the standpipe 1 is formed in one piece with it, that is to say it is formed from the actual standpipe by deformation thereof.
  • the cone section 17 is followed by a lower section 18 constricted with respect to the latter, on which the bottom 9 is formed.
  • This has a channel 19 which is open towards the inside of the standpipe 1 and which is connected in turn in the direction of the axis 3 to a substantially flat and radially extending to the axis 3 ring portion 20, which serves as a bearing surface for the axial roller bearing 8 and the is penetrated by the opening 12.
  • the channel 19 is approximately part-circular and has no sharp edges.
  • the transition 21 from the channel 19 to the ring section 20 is also rounded, i.e. not sharp-edged.
  • the flank 22 of the channel 19 which is inclined towards the ring section 20 can be clearly inclined towards the ring section 20, deviating from the pitch circle cross section.
  • the inner diameter D of the section 18 of the standpipe 1 is - as the drawing shows - several times larger than the diameter d of the piston rod 7. Also the diameter d 'of the roller bearing 8 is 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 inner diameter D is in the range from 30 to 50 mm.
  • the diameter d of the piston rod 7 is in the range of 10 mm. A range of 20 to 30 mm applies to the diameter d '.
  • the area of the pin 11 projecting below the base 9 with the washer 13 and the spring retaining ring 14 is likewise arranged sunk in the base 9, since the groove 19 protrudes downward over the ring section 20.
  • the spring retaining ring 14 is thus protected within the groove 19. It cannot be pulled off from high-flour carpets and the risk of injury is excluded if a user touches the lower area of the standpipe 1 with his foot.
