Definitions

  • the invention relates to a chair or similar seating furniture with at least three legs and a holding frame arranged between them in the region of the seat plane, to which the legs are attached and which serves as a support for a seat.
  • a chair with a holding frame which is received between the chair legs and connects the latter to one another and which also serves as a support for a seat surface is already known (cannot be documented in printed form).
  • the holding frame of this previously known chair consists of frame parts glued together at corner points, each of which extends between adjacent chair legs. The abutting and glued ends of the frame parts are bent relative to their longitudinal extensions at about 45 ° and formed as pins glued into corresponding transverse recesses in the chair legs.
  • the holding frame consists of solid wood or multi-glued laminated wood, which have considerable material thickness, the holding frame in the previously known chair is not sufficiently rigid. Naturally, a chair with such a frame has considerable weight. The latter is particularly disruptive when training as a stacking chair.
  • the object on which the invention is based is to create a chair or a similar piece of seating furniture with great torsional rigidity and load-bearing capacity, the weight of which should be markedly reduced compared to the known chair.
  • the holding frame connecting the legs to one another is designed as a box frame and each has an upper and lower cover plate, which are connected with lateral frame parts in a shear-resistant manner.
  • the box girder which is designed as a hollow profile in the seating furniture according to the invention, has a high load-bearing capacity and is above all extremely torsion-resistant and lightweight.
  • the lateral frame parts and / or the cover plates of the holding frame consist of multiply glued laminated timber in the seating furniture according to the invention, which need to have only small material thicknesses given the design of the holding frame as a box profile closed on the top and bottom.
  • the plywood can be plywood.
  • the holding frame is designed as a polygon corresponding to the number of legs, each with frames extending between adjacent legs and firmly connected to one another in the region of the corner points to which the legs are attached.
  • the frames can have at least approximately the shape of circular arc pieces that extend in an arc-shaped manner between the respective adjacent legs towards the interior of the seat surface, the ends of adjoining frames which are connected to one another abutting one another to form star-shaped corner points and are therefore areally connected to one another .
  • a reinforcing plywood insert can also be arranged between the interconnected ends of adjacent frames and connected, in particular glued, to the frame ends.
  • the legs of the seating furniture are connected to the holding frame by means of fittings attached to them on the inside. It did proven to be expedient if the fittings are designed as U-profiles with a web resting against the respective leg and one leg each overlapping the upper and lower cover plate of the box frame in the region of the star-shaped corners. This ensures a torsionally rigid connection between the respective corner of the box girder and the associated fitting and, via the latter, with the respective leg of the seating furniture.
  • the web of each fitting on the side facing the legs can also be designed as a pocket delimited by lateral web parts, in which the end section of the respectively connected corner of the box frame is received.
  • the chair 10 illustrated in FIGS. 1 and 2 is a stacking chair with two front and rear chair legs 11, 12, which are connected to one another by means of a box frame 14.
  • the box frame In addition to its function as a torsionally rigid connecting means for the chair legs, the box frame also forms a support for a seat surface 15 which is not of interest here. While the front chair legs 11 end at seat height, the rear chair legs 12 extend upwards beyond the seat surface and take between them a backrest 16.
  • the box frame 14 consists of four side frames 17 and an upper and lower cover plate 18, 19.
  • the frames are circular arc pieces made of multiply glued laminated wood, which end in four star-shaped corners 20 and, in the rest, spring back in an arc between these corners, so extend under the seat of the finished chair.
  • the ends 21 of adjacent frames 17 are brought together in the region of the corners 20 of the box frame 14 in sections running parallel to one another and glued to one another with the interposition of a reinforcing plywood insert 22 in each case.
  • the two cover plates 18, 19 are glued in a shear-resistant manner.
  • the cover plates extend into the corners 20 serving to connect the chair legs 11, 12 to the box frame.
  • the box frame 14 is a light-weight hollow profile with high torsional rigidity, the frames 17 and cover plates 18, 19 of which have only small material thicknesses and can consist, for example, of plywood.
  • a chair leg 11 or 12 is connected to the latter by means of a fitting 24.
  • the fittings are die-cast parts designed as U-profiles with a web 25 resting on the respective chair leg and two upper and lower legs 26, 27 which extend in the area of the respective corner from each other to the side remote from the chair leg 20 of the box frame 14 grip around the top and bottom.
  • the upper leg 26 rests on the upper cover plate 18 of the box girder 14, while the lower leg 27 is inserted into the lower cover plate 19 in the interest of the stackability of the chair 10 and is therefore flush with the underside thereof.
  • the webs 25 resting on the chair legs 11, 12 are correspondingly concave to the inner contour of the chair legs and are provided with two pins 28 arranged at a distance from one another and recessed in corresponding recesses in the chair legs, and fastened to the chair legs by means of retaining screws 29 which are concealed and screwed through the latter.
  • a groove-like pocket 31 bordered by lateral web parts 30 extends between the two legs 26, 27 of the fitting 24.
  • each fitting 24 extending from the web of each fitting 24 to the side facing away from the respective chair leg, which rest on the top and bottom sides of the two cover plates 18, 19 of the box frame, are glued to the cover plates and additionally by means of only indicated fastening screws 32, 33 screwed. Furthermore, the end sections of the star-shaped corners 20 of the box frame 14 are pressed with adhesive into the groove-like pockets 31 of the fittings.
  • the box girder 14 which is designed as a torsionally rigid hollow profile, is thus connected to the chair legs in a torsionally rigid manner by means of the fittings 24 in the region of the corners 20 formed by the glued ends of the frames 17.
  • the upper cover plate 18 of the box frame 14 is equipped with four perforations 35 arranged symmetrically to its surface area, into which latching cams arranged in a corresponding position on the underside of the seat surface 15 engage in a form-fitting but releasable manner.
  • the locking cams of the removable seat are not shown in the drawing.
