Definitions

  • the invention relates to a height-adjustable armrest for chairs, in particular for office chairs, with the specified in the preamble of claim 1 Features.
  • Such an armrest is known from DE 197 17 077 A1.
  • This Armrest has a vertical armrest base bracket that can be attached to the chair on, which is designed columnar.
  • On this base support is a telescopic armrest holder, the one at its upper end is essentially horizontal Armrest holds.
  • the locking device has on the one hand a row of arranged in the vertical direction on the base support Notches and on the other hand except by means of a release button Engagement with the locking recesses bringable locking element.
  • This known armrest is due to the construction of the locking devices the holder can be moved vertically, but not rotatable relative to the base support. So there is no degree of freedom for one if desired, the armrests can be rotated vertically Given axis.
  • DE 197 17 077 A1 proposes that the Armrest bearing armrest articulated at the upper end of the holder to store on the holder. This requires an additional constructive Effort that is exacerbated by the fact that the Armrest additional precautions in certain rotational positions meet as they are in the form of corrugated leaf springs in the backrest head the armrest according to DE 197 17 077 A1 are provided.
  • the object of the invention based on creating a height-adjustable armrest, in which one Positioning of the armrest in different, lockable rotary positions is made possible with simple constructive means.
  • This Task is by the specified in the characterizing part of claim 1 Features solved.
  • the present Invention In contrast to the prior art, where the rotatability of the holder was not given even when the locking device was released, the present Invention a rotation of the holder with the locking device unlocked authorized.
  • the armrest bracket does not require any additional ones Measures to create the desired degree of freedom for the Positioning of the armrest in different rotational positions.
  • a double function is, however, parallel to the first Row of recesses running second row of recesses Possibility created not only in the holder and thus the armrest certain height positions, but also in at least two different ones To lock the rotary positions. Both for changing the heights as well as the rotational position only one and the same release button for the Locking device can be operated, which in this respect is simple and user-friendly is.
  • the locking device 5 itself has on the one hand as essential components Release button 8 with a locking element 9 and the other one in the vertical direction V arranged on the inside of the cheek 7 on the base support 1 Row of notches 10 on.
  • the release button 8 with locking element 9 is accommodated in a pre-assembly housing, designated as a whole by 11, designed like a magazine and can be inserted into the holder 2 from above is.
  • a pre-assembly housing 11 is composed of two half-shells 12, 13, on the one hand a main body approximately pear-shaped in horizontal section 14 and a laterally protruding at its upper end Form stop plate 15.
  • the trigger button 8 itself is an elongated, extending in the vertical direction V. and slider 16 which is displaceable in the pre-assembly housing 11, an actuating handle protruding at a right angle from its upper end 17 is formed, the opening 18 between the two half-shells 12, 13 stands outwards.
  • the release button 8 two fork ends 19, 20 (Fig. 9) between them the locking element 9 of the locking device, which is designed as a so-called locking wedge 5 slidably in and against the locking engagement direction R (Fig. 2).
  • the fork ends 19, 20 are on the opposite side of the locking engagement direction R. the fork ends 19, 20 each with inclined to the vertical direction V.
  • Wedge surfaces 21 provided with lateral, pin-like projections 22 cooperate on the locking wedge 9 in a manner to be described in more detail and form a so-called wedge thrust transmission K.
  • the locking wedge 9 itself has a substantially cuboid guide body 23 which the sliding bearing of the locking wedge 9 in a guide 24 in the pre-assembly housing 11 in the locking engagement direction R takes over.
  • On the in the direction of locking engagement R facing side of the guide body 23 are finally in Vertical direction V two locking bolts 25 formed integrally one above the other, their contour and spacing of the shape and pitch of the recesses 10 is adjusted.
  • the locking wedge 9 is in the locking engagement direction R.
  • a helical compression spring 26 which between the inside of the pre-assembly housing 11 and the locking bolt 25 facing back of the locking wedge 9 is used.
  • the release button 8 is also opposed to the vertical direction V by another helical compression spring 27 under load, which between an abutment 28 in Pre-assembly housing 11 and the upper end of the slider 16 clamped is.
  • the armrest 4 If the armrest 4 is to be adjusted in height, it is on the operating handle 17 to pull the release button 8, whereby the wedge surfaces 21 the Locking wedge 9 over the projections 22 against the locking engagement direction R. move. As a result, the locking bolts 25 emerge from the corresponding Locking recesses 10 out and the holder 2 can in the vertical direction V pulled up and locked in the appropriate position.
  • the release button is in a defined relative position is released from holder 2 and base support 1 to each other. is no overlap position between locking pin 25 and the like Reached pair of recesses 10, the release button 8 is indeed pushed down by the helical compression spring 27, but the Locking wedge 9 can not yet be moved in the locking engagement direction R.
  • the limitation of the angle of rotation W is due to the guaranteed pear-shaped shape of the pre-assembly housing 11 in cross section, whose tapered housing part in the side opening the recess 6 moves.
