Definitions

  • the invention relates to a chair, in particular a swivel chair, with armrests, each of which is rotatably attached to a telescopically adjustable vertical support tube about a vertical axis, each armrest being displaceable in the horizontal direction along a straight guide relative to the axis of rotation which is fixedly connected to the support tube.
  • Such a chair is described for example in the utility model DE-GM 295 03 943.4 with older seniority.
  • the axis of rotation of the armrest is coaxial with the central axis of the support tube.
  • the invention is based, to achieve even greater variability of the different positions with simple means for positioning the individual armrest the task. Furthermore, a simple possibility should be created to disassemble the armrests from the support tube and, if necessary, to fix them again in a fixed position on the support tube.
  • the chair according to the invention is characterized in that the axis of rotation of the armrests is arranged eccentrically to the central axis of the support tube.
  • This arrangement not only opens up the possibility of bringing the armrest into a desired position even better by correspondingly pivoting and shifting it, but, as will be shown further below, simple disassembly and fixing of the armrest can also be achieved as a result .
  • the axis of rotation can be arranged in the form of an axle bolt in the area of the upper end of the support tube and a sliding body can be rotatably mounted over the axle bolt, which can be displaced in a sliding guide of a support plate of the armrest. It has proven to be advantageous if the axle bolt is mounted in a connection plate fixedly arranged at the upper end of the support tube. Furthermore, the axle bolt can be guided through the connecting plate Be screw formed, which is screwed into the sliding body and rotatably mounted in the connection plate. In this way, the rotary connection between armrest and support tube is easily accessible and can be removed by loosening the screw.
  • the inventive design opens up the possibility that the sliding body can be fixed in at least one predetermined position of the displacement path. This can be done by releasable locking.
  • this screw can be the axle bolt of the rotary connection between armrest and support tube, so that it is possible to provide a pivotable armrest with or without the possibility of displacement in the chair according to the invention.
  • two curved tube sections 3 are attached to the underside of the chair seat surface 2, onto which vertically aligned tube sections 4 are telescopically attached, which represent support tubes for the armrests 9 explained in more detail below.
  • the pipe sections 4 can be positioned relative to the pipe sections 3 in different height positions by means of a latching device 5, which is only indicated.
  • the armrests 9 are fastened to the upper ends of the support tubes 4 so as to be pivotable about an axis of rotation D.
  • the support tube 4 carries at its upper end an eccentrically arranged to the central axis M of the support tube 4 connecting plate 10 through which an outside of the support tube 4 and eccentric to the central axis M axis pin 6 is guided, which forms the axis of rotation D.
  • This axle pin 6 is designed as a screw, the head of which is rotatably mounted in the connection plate 10 and which is screwed into a receptacle designed as a screw nut 7, which is located in a rectangular sliding body 8 which is displaceable within a support plate 11 on the underside of the armrest 9 is arranged guided.
  • the support plate 11, on which a suitable cushion 12 is drawn, has a lower boundary wall 11.1 and an upper boundary wall 11.2 between which the sliding body 8 by straight lateral Guides 15 guided (see Figure 3) slides.
  • the upper boundary wall 11.2 is provided above the ends of the slot 13 with openings 14 for inserting the nut 7.
  • the length of the sliding guide receiving the sliding body 8 essentially depends on the length of the armrest 9 or the support plate 11.
  • Figure 2 shows on the left side in full lines the one extreme position of the armrest 9 relative to the axle pin 6 and on the right side dash-dot line the other extreme position. These extreme positions are also shown in FIG. 1, the two armrests also being shown in different angular positions relative to the seat surface 2.
  • FIGS. 3 and 4 show one possibility of fixing the armrest 9 or the support plate 11 in different positions of the displacement path.
  • a further receptacle 17 for a screw nut is arranged in the sliding body 8 and is accessible through an additional opening 16 in the upper boundary wall 11.2.
  • the support plate 11 can thus be fixed relative to the sliding body 8 in one of the positions specified by the bores 18.1 to 18.3.
  • an elongated hole 18 is made in the lower boundary wall 11.1 instead of three holes 18.1, 18.2 and 18.3, through which a screw can be screwed into the receptacle 17 of the sliding body 8. This makes it possible to also shift the support plate 11 into different positions relative to the sliding body 8.
  • the screw guided through the elongated hole 18 or the holes 18.1 to 18.3 and screwed into the receptacle 17 of the sliding body 8 can be the axle bolt 6 itself mounted in the connecting plate 10. It is therefore possible to fix the armrest 9 in one of the three positions while still rotatable but immovable with respect to the support tube 4, in that the axle bolt 6 is released from the receptacle 7 and guided through one of the bores 18.1 to 18.3 and into the receptacle 17 of the sliding body 8 is screwed in.
  • a clamping device is arranged between the connection plate 10 and the support plate 11.
  • This clamping device comprises a vertical threaded bore provided in the connection plate 10, in which a screw element 22, preferably having a high thread pitch, is guided, on the upper side of which a disk-shaped clamping element 21 and on the underside of which a horizontally extending actuating handle 20 are attached.
