Definitions

  • the invention relates to a chair with quickly adjustable energy storage after The preamble of claim 1.
  • EP 0 277 474 A1 discloses a chair of the type mentioned, in which the seat part by means of a parallelogram linkage arrangement against the Preload a spring element mounted vertically adjustable on the seat support is.
  • the backrest support is pivotally mounted on the seat support, with a Pivoting of the backrest support against the biasing force of the Spring element takes place.
  • the invention is therefore based on the object, a chair with the User adjustable energy storage so educate that a significant easier adjustment of the energy storage can be done.
  • the invention is characterized in that that the front end of the energy storage at one of the free, pivoting End of a seat edge near the handlebar is rotatably mounted and that the rear End of the energy storage at a free, pivoting end of the Lehnenizis is articulated and that this point of attack of the energy storage is designed adjustable and lockable.
  • a locking part is arranged, which consists essentially of a rack.
  • the arranged on the locking part Rack has a diverse subdivision. It can, for example preferably a number from eight to thirty different Locking recesses are arranged on the length of the rack, wherein These recesses each with one or more teeth of Spring control of the energy accumulator interact.
  • This handlebar pivots in the same way as the backrest support pivoted when the user leans against the backrest support.
  • Lean side end of the energy storage biased, creating an additional Preload of the energy storage takes place. So this is done in two ways biased when swinging down the backrest support, namely once through the movement of the swiveling part on the seat, namely on the backrest end of the energy storage, and on the other is the Force memory independently of this additionally compressed by that the front end of the energy accumulator attaches to said handlebar, the also in the direction of the backwards pivoting backrest support is pivotable.
  • the invention also provides that a pre-positioning of the Rast leopardes or the ratchet teeth of the energy storage in relation to the Rack is made on the locking part.
  • a pre-positioning of the Rast leopardes or the ratchet teeth of the energy storage in relation to the Rack is made on the locking part.
  • Such Prepositioning always ensures that when swinging the Backrest support always a locking tooth of the energy storage of an associated Latching the locking part opposite. This will be the case Making the locking connection undesirable scratching and scraping noises avoided.
  • the invention accomplishes this by having an index pin at the free, pivotable end of the force accumulator is present, the spring loaded in a assigned indexing rail. So this indexing track is there different tilt angle of the energy storage before, before this ever in the latching recess is engaged on the locking part. This way will always ensured that the locking tooth on the energy storage always in Comparison to a corresponding recess on the Locking part is located.
  • the invention also provides a stepless one in another embodiment Locking in front, because it is easily possible to intervene between the Energy storage and the associated locking part as a displacement guide perform at certain points (for example by means of an eccentric) can be locked.
  • a stepless engagement of the lean side end of the force accumulator in the associated locking part is hereby expressly claimed.
  • a work chair which consists of a Lifting column 5 is fixed in the seat support 7.
  • a backrest support 1 On the seat support 7 engages a backrest support 1, each with a right and left tab. 2 (see Figure 3) is pivotally hinged to the seat support 7.
  • the respective tab 2 rotatably mounted in a bearing 8 on the seat support 7.
  • the upper seat bearing 3 is used for pivotally receiving a not closer shown seat plate, which via a tab, not shown attaches this seat bearing 3.
  • the front end of the seat plate is another not shown tab on a front seat bearing 4 pivotally attached.
  • the tabs are firmly connected to the seat plate.
  • a pivot bearing 24th is present, which receives a handlebar 23, thus in the Arrow directions 37 is formed pivotable about this bearing 24 around.
  • the front end is not closer shown seat plate received in the front seat bearing 4, so that this front end pivotable with the associated link 23 is trained.
  • the backrest support each with a tab. 2 connected, wherein the tab 2 is received in the bearing 8.
  • This bearing 9 is the pivot bearing for a locking part 10.
  • the locking member 10 consists essentially of two parallel mutually arranged tabs 11, which is a substantially U-shaped part form, in the central region of a rack 12 is arranged.
  • the locking member 10 is thus rotatably connected to the tab 2 and makes the same because of the movement of the backrest support in the direction of arrow 34 Movement with, where it pivots about the bearing 8.
  • bearing 9 is used, because on the designated Bearings in the bearing 9 store other parts, namely the particular Parts for the locking plate 26 and the hand-adjustable locking the Tilt adjustment.
  • the spring guide of the compression spring 21st from a lower spring guide 20, in which the guide pin 19 is arranged is and arranged from a displaceable thereto, upper spring guide 22nd
  • the upper part of the spring guide 22 is in the upper seat bearing. 4 swiveled.
  • the adjustable locking of the lower spring guide 20 is now carried out by that upon pivoting of the lever 16 in the direction of arrow 38, the tab 36 to pivoted the pivot point of the axis 17 and hereby the slot is transverse to Direction to the longitudinal axis of the helical compression spring adjusted. This will be the Attack point of the compression spring 21 changed to the backrest support, because the entire end of the spring guide 20 is now pivoted in the direction of arrows 33.
  • the tooth 32 can be in unloaded backrest carrier in any Recess 31 are engaged on the locking part 10.
  • the backrest support 1 is biased only with a small biasing force (Clamping position of Figure 4), whereas, when a lower tooth 32 on lower end of the locking part is used for the locking engagement, the Power storage with a high biasing force on the backrest support 1 acts (Clamping position of Figure 5).
  • the figure 2 shows a middle Clamping position.
  • a rotary button not shown for a Locking the pivoting movement of the backrest and thus of the backrest support. 1 is available. This locking is effected by that with the Locking member 10 is connected to a forward-directed longitudinal lever 28, a front guide recess 29 for the longitudinal guidance of a there slidably arranged locking plates 26 forms.
  • the locking plate 26 are a series of consecutive Holes 27 arranged, and the locking of the backrest carrier in one Any pivot position is possible because of the locking plate 26 a spring-loaded pressure pin (catch or index pin) are engaged can, thereby forming a connection between the locking member 10 and the associated backrest support 1 is made in the region of the seat support 7.
  • the backrest support 1 is fixedly coupled to the seat support 7 and the Backrest support can no longer in the direction of arrow 34 and in the opposite direction to be pivoted for this purpose.
  • the locking plate 26 moves analogous to the pivoting movement of the Back support in the directions of the arrow 34 and in the opposite direction to this, which is shown by the arrow direction 30.
  • the spring-loaded locking pin (not shown in the drawing) sits on the seat support in the area of the front bore 27. On the other hand, if the backrest support 1 in a pivoted half pivoted position and then locked, then moves the bore 27 in the locking plate 26 in alignment with match the front hole 27 on the seat support, so now in the middle hole the locking plate of the locking pin is inserted.
