Definitions

  • the invention relates to a chair according to the preamble of claim 1.
  • Such a chair described in US 5 407 249 A is equipped with armrests, at which on the one hand the support tube is pivotable about two vertical axes, while on the other hand, the armrest itself relative to the support tube about a further vertical axis pivotable and additionally essentially horizontally in the longitudinal direction is movable.
  • This chair is located directly on the armrest assigned vertical axis of rotation coaxial to the vertical central axis of the end section the support tube to which the armrest is attached.
  • This last-mentioned axis of rotation is essentially formed by a bearing bush inserted into the end of the supporting tube, into which a bearing journal is inserted, which carries a holder on which a sliding body is screwed, along which the armrest support plate provided with a sliding guide is displaceable in the horizontal direction.
  • the well-known construction is therefore extremely complex in terms of construction.
  • the invention has for its object in the area of the armrest assigned axis of rotation and the sliding construction of the armrest with simple Adequate variability for different armrest positions to reach.
  • This arrangement not only opens up the possibility of pivoting accordingly and moving the armrest to bring it into a desired position even better but, as will be shown below, it can also be done with simple constructive means Medium easy disassembly and fixation of the armrest achieved become.
  • the training according to the invention opens in simple way the possibility that the sliding body in at least one predetermined position Trajectory is fixable. This can be done by a releasable locking happen. It is also possible to fix the slider by Screwing in a screw by a given one Hole in the lower boundary wall of the support plate in a receptacle of the sliding body.
  • the axle bolt can be screw Be a slewing ring between armrest and support tube, so that it is possible with the chair according to the invention optionally a swiveling armrest with or without Provide possibility of displacement.
  • the Armrests 9 at the upper ends of the support tubes 4 an axis of rotation D is pivotally attached.
  • This helps the support tube 4 is eccentric at its upper end arranged to the central axis M of the support tube 4 Connection plate 10 through which an outside of Support tube 4 and eccentric to the central axis M lying axle pin 6 is guided, the Axis of rotation D forms.
  • This axle pin 6 is as Trained screw whose head in the Connection plate 10 is rotatably mounted and in a receptacle designed as a screw nut 7 is screwed, which is in a rectangular Slider 8 is located within a Support plate 11 on the underside of the armrest 9 is arranged displaceably guided.
  • the Support plate 11 on which a suitable cushion 12 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.
  • a suitable cushion 12 In the lower boundary wall 11.1 of the support plate 11 there is a slot 13 through which the Axle pin 6 is guided.
  • the upper boundary wall 11.2 is above the ends of the slot 13 Openings 14 for inserting the screw nut 7 Mistake.
  • the length of the sliding body 8 receiving sliding guide 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 Axle pin 6 and dash-dotted on the right side the other extreme position. In Figure 1 these are Extreme positions are also shown, whereby additionally the two armrests in different Angular positions shown relative to the seat 2 are.
  • FIGS. 3 and 4 see the armrest 9 and the support plate 11 in different positions of the displacement path fix.
  • FIG Slider 8 another receptacle 17 for one Screw nut arranged by an additional Opening 16 in the upper boundary wall 11.2 is accessible.
  • the bottom Boundary wall 11.1 in one Direction parallel to slot 13 three holes 18.1, 18.2 and 18.3 arranged by which screws insertable and into the receptacle 17 of the sliding body 8 in a corresponding position of the sliding body 8 are screwable.
  • connection plate 10 is between the connection plate 10 and the support plate 11 a clamping device arranged.
  • This clamping device comprises one in the Connection plate 10 provided vertical threaded bore, in which a preferably a high thread pitch having screw element 22 is guided, at the Top of a disc-shaped clamping element 21 and whose underside is a horizontally extending one Operating handle 20 are attached.
