Definitions

  • Chair in particular an office chair with a vertical column extending from a pedestal, a cantilever projecting from the upper end of the column, a seat plate connected to the cantilever, supported in the rear area by a leg spring fixed to the column, and a resiliently supported by the leg spring Backrest.
  • DE-OS 37 41 472 shows and describes a chair in which the die plate is pivotally mounted at the front end of the boom and the backrest is pivotably attached to the upper end of the column via a bracket.
  • a leg spring is attached to the arm and supports the rear area of the seat plate and the backrest.
  • European patent 0 105 955 Another solution of the type mentioned, but with a different concept as a whole, is shown in European patent 0 105 955.
  • the seat plate is divided transversely into a front and rear partial plate.
  • the front section plate is rigidly attached to the boom, while the rear section plate is supported by a leg spring fixed to the boom and at the top of the column.
  • the backrest is attached to the rear section plate and the column via handlebars and spacers.
  • the invention has for its object to provide a chair of the generic type, which not only meets the requirements of functionality and ergonomics, but manages with few moving parts and can be produced with little effort.
  • the seat plate is firmly connected to a rigid support plate mounted in the area of its front third, that the seat plate is firmly connected to a rigid support plate in the area of its rear third is which carries on its underside sleeves for displaceable, latchable reception of two open ends of the overall U-shaped leg spring, and that the seat plate is flexible at least in the region of its middle third.
  • the chair Since the seat plate is elastically flexible in the central area, the chair does not require any joints, which are usually provided for the resilient pivoting movement of the die plate and the backrest.
  • the rigid and large-area connection of the front and rear end region of the seat plate with the extension arm and the rear support plate enables a stable solution.
  • With only one, relatively simple leg spring both the die plate and the backrest are held resiliently.
  • the leg spring also has an additional function, since it can be locked on the underside of the rear support plate and in this way enables the spring mechanism to be blocked. Apart from the corresponding locking mechanism, no moving parts are required.
  • the sleeves can comprise easily pivotable bearing bushes.
  • the backrest is preferably attached to the rear support plate via a suitable intermediate piece.
  • This intermediate piece can in turn exert a spring effect.
  • the apex area of the overall U-shaped leg spring is adjustably supported on the underside of the front arm. Adjusting the distance to the bottom of the boom changes the preload.
  • the legs of the leg spring extending from the front apex region are preferably placed around pins projecting laterally from the upper end of the column and extend from the top of the pins to the sleeves.
  • a chair according to the invention according to FIGS. 1 to 3 has a base frame 10 in the form of a roller frame, from which a vertical, height-adjustable column 12 extends, which contains a gas spring 14 on the inside. From the upper end of the pillar 12, an obliquely upstanding arm 16 projects forward with respect to the seat direction. On the front end of the boom 16 is a substantially horizontal, transverse to the seat direction, rigid support plate 18 is attached (Fig. 1 and 2).
  • the seat plate 20 can carry an upholstery, not shown.
  • a support plate 22 which extends across the seat plate and which, like the front carrier plate, is essentially rigid.
  • the support plate can be a plastic plate provided with stiffening profiles, as will be explained in more detail later.
  • the two legs of the leg spring 24 run obliquely to the rear and in each case in a helix 30, 32 around pins 34, 36, which project from the upper end of the column 12 on both sides.
  • the pins 34, 36 are formed by a continuous tube section placed in front of the upper end of the column, which will be discussed again later.
  • the rear ends of the leg spring 24, designated 38.40, run from the upper side of the pins 34, 36 to the underside of the support plate 22.
  • the ends 38.40 are guided to be longitudinally displaceable and lockable, as will be explained later with reference to FIG shall be. In this way, the rear end region of the seat plate 20 is supported by the support plate 22 on the ends 38, 40 of the leg spring with a corresponding spring action.
  • the rear support plate 22 is angled at an obtuse angle at its rear end and forms a support surface 42 there, to which a backrest 44 can be fastened in a suitable manner.
  • the connection between the support surface 42 and the backrest 44 can be elastic and can comprise, for example, a further leg spring 46 which is integrated in the backrest 44 and the ends of which are inserted into corresponding receptacles in the support surface 42.
  • the horizontal tube section which forms the two pins 34, 36 on the front of the column 12, can at the same time on both ends for receiving adjusting levers 48, 50 for height adjustment or for locking the seat plate serve.
  • the actuating lever 48 has a shaft, not shown, which lies in the interior of the pin 34 in the form of a tube, at the end of which a pressure element 52 is arranged, which acts on a release pin 54 at the upper end of the gas spring 14.
  • the other control lever 50 also has a shaft that actuates a Bowden cable 56, which will be discussed again later.
  • armrests 58, 60 are fixed to the pins 34, 36 in accordance with FIGS. 1 and 3.
  • the support plate 22 has on the underside a rib structure shown in FIG. 4 for stiffening.
  • the two ends 38, 40 of the leg spring 24 are guided so as to be longitudinally displaceable in two sleeves 62, 64 and 66, 68 that are axially spaced apart.
  • needle bearings 70 are located in the sleeves above and below the spring ends, that is, in the main loading directions.
  • both the front carrier plate and the rear support plate 22 extend substantially over the entire width of the seat plate 20 and are firmly connected to the latter .
  • Lateral sagging of the support plate 22 is excluded by its torsional rigidity in connection with the four-point mounting of the spring ends in the four spaced sleeves 62, 64, 66, 68.
  • a bearing can also be used which consists of a cylinder tube, a cylindrical bearing cage made of plastic and an annular ball seat arranged at the ends thereof.
  • Such cylinder guides are used for example in machine tools.
  • a cross member 72 running transversely to the support plate 22.
  • a cross member 72 running transversely to the support plate 22.
  • On the Traverse 72 is a plurality of locking teeth 74 into which a bolt 76 can enter.
  • the latch 76 is biased into the locking position by a spring 78.
  • the Bowden cable 56 already mentioned is guided to the underside of the support plate 22 and connected to the bolt 76, so that the locking can be released by actuating the adjusting lever 50 (FIG. 3).
  • a locking mechanism of a different type can be used, for example also a continuously adjustable gas spring.
  • FIG 4 shows the rest of the rear support surface 42, which serves to accommodate the backrest.
