Definitions

  • the invention relates to a chair frame for chairs with different seat and backrest parts, which consists of two frame side parts, each consisting of a unit from a rear leg, a front leg and an armrest, the rear legs are connected to the front legs above the seat height and Armrests are brought down to the seat height and connected to the seat part.
  • a chair frame of this type is known from DE 87 01 032 U1.
  • the frame side parts form a solid unit, which is welded together from bent flat material sections and which is firmly connected to the seat part and the backrest part, i.e. is also welded, the backrest part and the seat part are additionally connected to one another via a backrest support.
  • the chair has a fixed shape with the frame side parts, the seat part and the backrest part.
  • a chair is known from US Pat. No. 2,991,123 and DE-PS 390 870 in which the front legs extend beyond the connection points with the rear legs, are designed as armrests and are used to attach the backrest part.
  • a chair is known from two one-piece frame side parts, to which a one-piece seat shell is attached, which is fastened in the connection points between the front legs and rear legs and on extensions of the front legs.
  • the rear legs of the frame side parts are slightly inclined forward and extended beyond the junctions with the front legs, that the armrests are connected to the upper ends of the rear legs and in each case led up to the backrest height are that the frame side parts on the mutually facing insides at seat height on the rear legs, the front legs and the front ends of the armrests and the rear ends of the armrests at the backrest height carry connection elements, and that with these connection elements an integral part of the seat part and the backrest part
  • Seat shell or a seat plate designed as a seat part and a separate backrest part can be attached, which are provided with complementary connecting elements arranged in a corresponding distribution.
  • a sufficiently large footprint of the chair is created and the frame side parts can be connected quickly and easily with the connecting elements arranged in this way to a one-piece seat shell comprising a seat part and backrest part or with a separate seat part and backrest part if these are provided with complementary connection elements in an appropriate arrangement and distribution.
  • a chair When assembled, a chair is always created that is very stable and, with the exception of the free ends of the front legs and rear legs in the area of the stand side, no longer has any protruding sections of the frame side parts, since with the seat part and the backrest part all ends of the frame side parts are occupied.
  • connection elements on the frame side parts are designed according to a simple design as plug pins and the complementary connection elements on the seat and backrest parts as plug receptacles adapted thereon.
  • the plug pins are preferably fixed in the fit and / or press fit in the plug receptacles.
  • the front legs are arch-shaped and convexly curved upwards. This gives the connecting element attached to the front leg at seat height a greater distance from the connecting element attached to the rear leg.
  • the armrests can be used both at the seat height and at the backrest height for attaching seat and backrest parts, it is further provided that the armrests are arched and convexly curved upwards and that the armrests run approximately parallel to the front legs.
  • the aesthetic appearance of the chair frame can be varied in a simple manner in that the rear legs, the front legs and the armrests are designed as a hollow profile section with the same or different cross-section.
  • a clear support of the seat part is achieved in that the connecting elements of the front legs lie between the connecting elements of the rear legs and the connecting elements of the front ends of the armrests at seat height.
  • the seat can be adjusted so that the connecting elements of the rear legs, the front legs and the front ends of the armrests lie approximately in a plane that is parallel or slightly inclined to the base of the frame side parts.
  • connection elements of the armrests located at the backrest height are offset to the rear relative to the connection elements of the rear legs arranged at the seat height.
  • the left frame side part 10 is formed from the straight rear leg 11, the upward convex and forward front leg 13 and the armrest 15.
  • the right frame side part 20 is composed of the rear leg 21, the front leg 23 and the armrest 25.
  • the front legs 13 and 23 are firmly connected to the rear legs 11 and 21 somewhat above the seat height, e.g. screwed.
  • the armrest 15 or 25 lies in the same plane as the rear leg 11 or 21 and the front leg 13 or 23.
  • the rear leg 11 or 21 is extended beyond the seat height and carries the armrest 15 or 25 at the upper end, as the connection point 19 and 29 shows.
  • the armrest 15 or 25, starting from the rear leg 11 or 21, is pulled back up to the backrest height and pulled forward down to the seat height.
  • the frame side parts 10 and 20 carry the rear legs 11 and 21 on the mutually facing inner sides at seat height, on the front legs 13 and 23 and on the front ends of the armrests 15 and 25, connecting elements 12, 14, 17 and 22, 24 designed as plug bolts ; 27, which are arranged approximately in a plane that runs parallel or slightly inclined to the base of the chair frame.
  • the connection elements 14 and 24 of the front legs 13 and 23 lie between the connection elements 12, 22 and 17.27 of the rear legs 11 and 21 and the front legs 13 and 23.
  • the rear ends of the armrests 15 and 25 are at the backrest height with the connection elements 16 and 26 provided.
  • the frame side parts 10 and 20 can consist of hollow profile sections which can have the same or different cross sections. Except for the connection elements, however, both frame side parts 10 and 20 can be assembled from uniform hollow profile sections.
  • the connecting elements are then attached to the subunits prepared in this way on the other side, thus completing the frame side parts 10 and 20.
  • This structure of the chair frame is also identical in the chairs according to FIGS. 2 and 3. The only difference is the design of the seat and backrest part.
  • Fig. 1 the one-piece seat shell 30 is shown, which combines the seat part and backrest part.
  • the seat shell 30 carries complementary connection elements 31, 32, 33 and 34 on both sides.
  • These complementary connection elements 31 to 34 can be designed as plug-in receptacles, which form the connection elements 12, 14, 16, 17 and 22, 24, 26, 27 the frame side parts 10 and 20 in the fit and / or press fit or can also snap.
  • the connections of the connection elements 12, 14, 17 and 22, 24, 27 of the frame side parts 10 and 20 with the complementary connection elements 33, 32, 31 of the seat shell 30 and at the backrest height are obtained at seat height the connecting elements 16 and 26 of the frame side parts 10 and 20 with the complementary connecting elements 34 of the seat shell 30.
  • the seat shell 30 can be provided with a shell cushion 35.
  • the seat plate 30.1 and the separate plate-shaped backrest 30.2 can be attached to the same frame side parts 10 and 20.
  • the seat plate 30.1 has the complementary connecting elements 31, 32 and 33 on both sides, which are aligned and adapted to the connecting elements 12, 14, 17 and 22, 24, 27 of the frame side parts 10 and 20 arranged at the seat height.
  • the separate backrest 30.2 has complementary connecting elements 34 on both sides for connection to the connecting elements 16 and 26 at the rear ends of the armrests 15 and 25, which are offset relative to the connecting elements 12 and 22 on the rear legs 11 and 21 to the correct position of the Backrest 30.2 to get the seat plate 30.1.
  • connection elements 16 and 26 are arranged on the frame side parts 10 and 20 at the backrest height
  • the backrest 30.2 also assumes the correct height on the finished chair. 5 shows that the connections between the frame side parts 10 and 20, the seat plate 30.1 and the backrest 30.2 are unchanged. The same also applies to the chair design according to FIGS. 3 and 6. It is only instead of the plate-shaped gen backrest 30.2 uses a molded backrest 30.3.
  • the cushion 35.1 for the seat plate 30.1 and the cushion 35.2 or 35.3 for the backrest 30.2 or 30.3 adapt to the shape of these parts.
  • upholsteryed seat shells, seat plates and backrests can of course also be used.
