Definitions

  • the invention relates to an office chair a backrest, the backrest support pivotable on a horizontal axis stationary chair holder is stored such that the backrest support against the Pressure of a return spring can be pivoted backwards is and by means of the restoring force the return spring one facing forward Movement of the upper body of the seat user follows.
  • a special feature of such office chairs trackable backrest consists of that for certain office jobs where the back of the seat user is static
  • the backrest support needs support in a swiveled forward Position by means of a locking device should be lockable.
  • the invention was therefore based on the object a new return spring or a new one To develop the spring package that the desired has greater dynamism and (as before) in one forward pivoted position of the backrest support can be blocked or locked where there was another task, that the searched return spring or the new return spring package you are looking for same outer dimensions, mounting connections and should have operating procedures, to optionally also against a gas pressure spring or a gas pressure / metal spring assembly known Design to be replaced.
  • the return spring in the form of a mechanical helical compression spring is formed, those between one assigned to the backrest support Thrust bearing and one assigned to the chair holder Thrust bearing is arranged, and that coaxially in the helical compression spring plunger attached to a thrust bearing exists in one in which other thrust bearing attached immersion sleeve runs, with the plunger moving radially has locking stops that can be opened on the outside, those in the issued state and in a largely extended position of the plunger on the peripheral edge of the Mount the immersion sleeve.
  • the new plunger lockable metal pressure spring can with an additional outer Coil compression spring that coaxially the inside encloses the first metal compression spring, be combined into a metal spring package, like this from the drawings for this patent application is removable.
  • the plunger lock ensures this the metal compression spring that the backrest support in a forward position of the backrest can be locked just as easily, like the seat user of the old gas spring technology knows.
  • Such spreading scissors (de facto two in opposite directions around a common scissor axis movable rocker arm) has the advantage that squeezing the handling ends the spreading scissors in the simplest way and done permanently by spring force can.
  • the plunger with his Piston area in which the end pieces of the Spreading scissors are positioned inside the immersion sleeve the remain end pieces intended as locking stops ineffective, since it is only on the inner wall slide along the immersion sleeve.
  • swiveled forward Position of the backrest can the end pieces take effect, namely, when they come out of the pocket are and as locking stops on the Sit on the circumferential surface of the immersion sleeve.
  • Another improvement of the new plunger lockable Metal compression spring is after Claim 2 characterized in that the Has circumferential edge of the immersion sleeve gradations, which correspond to the width of the Locking stops designed and in axial Staggered towards each other are so that by a rotational movement the immersion sleeve around its axis other graduated peripheral edge of the immersion sleeve for mounting the locking stops can be used. Accordingly, can the user of the seat preferred by him front locking position of the backrest select or set.
  • FIG. 1 is a simplified side view the chair holder 5 of an office chair with a trackable backrest support 6 (swiveling about axis 7) and one synchronously thus pivotable seat support 8 shown. So that the synchronous adjustment is executable, the backrest support 6 via the axis 9 with the seat support 8 connected.
  • the seat support has at the front end one firmly attached to it Sliding axis 10 in two congruent Slot control cams 11 in the side walls the chair holder 5 is guided.
  • the control curves run from the front down to the back rising at the top, so that there is an increasing Displacement of the sliding axis 10 results when the backrest support 6 from its illustrated front backrest position in his (not shown) back back position is moved.
  • the spring assembly 12 is shown in FIGS. 2 to 4 shown in more detail. It consists of one inner cylindrical helical compression spring 14 and an outer, coaxially arranged Helical compression spring 15. Both springs are separated from each other by the pipe section 16.
  • the inner helical compression spring is between the disk 17 and the pot housing 18th clamped, and the outer helical compression spring lies on the one hand on the plate disk 17 and on the other hand on the screw cap 19 for the purpose of changing the preload the outer helical compression spring 15 on the external thread of the pot housing 18 can be adjusted axially.
  • the plunger 21 is integral with the Plate 17 and the one shown on the left Crosshead 22 formed. He has one slot-like milling in which the two Rocker arms 23 and 24 of an expanding shear the scissors axis 25 are attached.
  • the End pieces 26 and 27 of the spreading shears run in the position shown in FIG Plunger in the immersion sleeve 20 and sit in the shown in Fig. 4 Position of the plunger on the peripheral edge the immersion sleeve 20.
  • the handling ends 28 and 29 of the spreading scissors are permanent by the U-shaped Leaf spring 30 loaded so that the end pieces 26 and 27 permanently the trend have, radially outwards from the cutout extend the plunger 21 and on the To sit on the peripheral edge of the immersion sleeve 20, as soon as the maximum extended from the immersion sleeve Position of the plunger this allowed.
  • the spring assembly is then blocked i.e. the backrest support 6 of the office chair is then locked.
  • a lever arrangement 30/31 (see Fig. 1) press on the feed wedge 32 acts by means of the handling ends 28 and 29 the spreading scissors against the pressure the U-shaped leaf spring 30 moved apart can be, so that the end pieces 26 and 27 of the spreading scissors again in their in the milling of the Plunger retracted position in which they with the plunger 21 in the Immersion sleeve 20 can be retracted.
  • the ones at the bottom of the pocket Rubber balls 33 serve as an end stop at Retracting the plunger into the immersion sleeve.
  • the lever arrangement 30/31 in the chair support 5 the office chair is in a known manner built that by an at least 90 ° swivel of the smaller lever 31 the larger lever 30 in a permanent position (Stop position) can be brought in the larger lever 30 the feed wedge 32 mechanically in the position according to Fig. 2 fixed in the locking the backrest support 6 not possible is.
