Definitions

  • the invention relates to the field of furniture industry. It relates to a cantilever chair, which is suitable for both office and for living spaces.
  • Cantilever chairs are known in various designs, see z. DE 203 17 070 U1, DE 196 34 058 C2, DE 40 33 972 A1, DE G 85 34 420.6. They are very much stressed by the high bending forces that occur when using the chair, especially in the area of the floor. In order to accommodate these high bending forces with sufficient safety, cantilever chairs are therefore generally made of a metallic tube frame with a sufficiently large diameter, which is connected to the seat and the backrest of the chair.
  • the tubular frame usually has a U-shaped, lying on the bottom foot part, which consists of two lateral pipe sections and a rear transverse pipe section, which connects the two lateral pipe sections together.
  • the lateral pipe sections turn into vertical pipe sections that form the legs of the chair frame. These can also be bent slightly obliquely to the rear and pass into armrests, as described for example in DE 203 17 070 U1.
  • crossbeams arranged in a straight or even bent form are arranged between the legs at their upper end (see, for example, DE 203 17 070 U1 or complicatedly designed mounting plates which are arranged centrally under the seat (see, for example, DE 196 34 058 C2)
  • additional backrest supports which are fastened to the seat or tubular frame, for example, are necessary for the backrest of the seat and backrest of the known cantilever chairs are usually conventional and have a more or less rectangular shape.
  • a disadvantage of this known prior art is that the cantilever chair frames are expensive to produce because of their many parts; In particular, to achieve a closed bottom view of the chair, the cross-connection must be subsequently covered. In addition, a relatively large storage space for the racks is necessary because of the existing crossbeams, as they can not be stacked to save space.
  • the aim of the invention is to avoid the mentioned disadvantages of the prior art.
  • the invention is based on the object to develop a comparison with the known prior art improved cantilever chair, which can be easily produced from relatively few parts, which is less expensive and the frame can be stacked to save space during manufacture.
  • the frame is very simple due to the absence of the cross-beam on the tubular frame and has only a few parts.
  • the bottom view of the chair according to the invention is closed from the outset, d. H. There is no need to install expensive additional covers.
  • the tube frame is easy to stack before the final assembly of the chair, so that advantageously only a small storage requirement is needed.
  • the angle ⁇ between the chair leg and the receiving pin is 45 °, because when setting the back plate by the vertical path component also results in a horizontal component in the same size, whereby a gap formation between the frame and the backrest shell is avoided , At the same time, this system also compensates for different strengths of the cover made between the backrest plate and the frame.
  • a receiving lug is arranged on the chair leg through which a screw is guided, with the aid of which a voltage between the frame and the back shell is generated.
  • Fig. 1 shows schematically in perspective a cantilever chair according to the invention in the assembled, i. ready for use state. Externally visible that the chair consists of a tubular frame 1, a seat 5 and a backrest 4.
  • the backrest 4 has, in contrast to the known cantilever chairs, a laterally closed shell shape and can be made of either plastic, but also z. B. be made of wood. In the present embodiment, it consists of rigid foam (PUR). It is covered with a cover made of fabric, leather or the like.
  • PUR rigid foam
  • the upper edge 4 'of the backrest 4 rises at both Pages from the front, the tubular frame 1 adjacent end to the back center steadily, so that the height of the backrest 4 in the region of the spine of a seated is largest. This achieves a comfortable sitting posture.
  • An advantage of this embodiment is also that by the sloping down height of the backrest 4, its upper edge 4 '(upper boundary surface) can therefore be used in the front part each as an armrest for the arms of a user.
  • the backrest 4 may also have a uniform height in another embodiment.
  • the seat 5 of the cantilever chair according to the invention is arranged.
  • the tubular frame 1 is made of a metallic material, here the steel ZSTE 420. It is formed from two vertical or slightly obliquely backward leaning chair legs 1 'and connected to these, resting on the floor U-shaped foot part, which in turn consists of two lateral pipe sections 1 "and a rear transverse pipe section 1' '' The transversely arranged pipe section 1 '' 'connects the two lateral pipe sections 1' 'to one another, wherein the transition pieces between the various pipe sections are in each case formed as arcuate pipe sections 1' ''
  • the individual pipe sections 1 ', 1' ', 1' 'and 1' '' could also consist of a continuous, correspondingly curved, single tubular strand or the sections 1 ', 1 "and 1"' of the tubular frame 1 could, in a further exemplary embodiment, also be connected to one another without arcuate tubular sections intervening therebetween connected be.
  • FIG. 2 the cantilever chair of Fig. 1 according to the invention is shown in an exploded view. With reference to this drawing, the invention is apparent in detail.
  • FIG. 2 In the lower part of Fig. 2, the tubular frame 1 of the chair is shown. It can be seen that in accordance with the invention, in each case two receiving pins 2 arranged at an angle to the rear and upwards are fastened to the chair legs 1 'in the upper region.
  • the angle ⁇ between the chair legs 1 'and the receiving pins 2 is in the range of 30 to 60 °, preferably 45 °.
  • Below the lower receiving pin 2 a receiving lug 3 is fixed in each case on the chair leg 1 ', through which a screw 6 can be guided.
  • the backrest 4 is shown in detail. It has at its lower end an inwardly extending backrest plate 9, on which comes to rest during assembly of the cantilever chair seat 5. Furthermore, in the backrest 4, in the side parts of the shell, in each case 2 corresponding openings 8 for receiving the receiving pins 2 are arranged. These openings 8 are also inserted at an angle ⁇ obliquely upward and are so deep that they completely enclose the receiving pins 2 after assembly of the chair.
  • the receiving lug 3 has in the initial position at a distance from the hinged back plate 9, whereby when screwing on the material strength of the receiving lug 3, a tension is built up, the set amounts, which arise during the use of the chair, can compensate. In conjunction with the slope of the receiving pins 2 is thereby ensured that the set amounts always compensate so that no gap between the tube frame 1 and the back plate 9 is formed.
  • the frame is simple and has few parts.
  • the bottom view of the chair according to the invention is closed from the outset, d. H. There is no need to install expensive additional covers.
  • the tubular frame 1 is easy to stack before the final assembly of the cantilever chair, so that advantageously only a small storage requirement is needed.
  • the tube frame 1 could also have only one receiving pin 2 in each chair leg 1 'and accordingly only one corresponding opening 8 may be provided in each side part of the backrest 4.
