Definitions

  • chair surfaces which have to meet high requirements, especially as seating surfaces, are either left as uncomfortable hard surfaces, usually made of wood, plastic or metal, or are upholstered and covered in an elaborate manner, or with a less resistant weave made of textile material, reed or Plastic covered.
  • defects have to be accepted that have a very negative effect on the weight of the chair, its manufacturing price, the seating comfort, the lifespan, the environmental compatibility or the versatility in use.
  • Intertwined material in particular is problematic. If elastic material, for example plastic, is used, there is a risk that the fabric will stretch under the continuous load, flow, and the surface will soon lose its original shape. In the case of brittle material that prevents this flow, the strips of the braid are strained by the repeated bending. At the same time, bulges are formed during braiding that are sensitive to mechanical stress.
  • elastic material for example plastic
  • the invention makes it possible to circumvent these design defects.
  • Seating surfaces are made possible that are light, inexpensive to manufacture, comfortable, robust, ecologically problem-free and versatile in use and are therefore ideal for many types of chairs and loungers.
  • FIG. 3 shows a cross section of a frame analogous to FIG. 1, but with an additional, internal clamping frame,
  • FIG. 5 shows the cross section A of the frame of FIG. 4,
  • FIG. 6 shows the longitudinal section B of the frame of FIG. 4,
  • Fig. 8 is a one-sided glued slat, with the frame forming a surface, in cross section and
  • Fig. 9 is a cross section glued in a groove of the frame lamella.
  • the slats 2 are also adapted in dimension, shape and mutual distance to the different conditions and requirements.
  • the dimension, the amount of preload and the elasticity of the slats are also decisive for the character of the surfaces under load.
  • the simplest way to pretension the slats 2 is achieved by counter-tensioning the frame 1 during the fixing of the slats.
  • a pretensioning device is the assembly of a second frame 3, on which the slats 2 are fastened, and which is then clamped into the supporting frame 1 by means of a tensioning device 4.
  • lamellae 5 on a second surface likewise prestressed in the frame 1 and lying directly below the first or at a greater distance therefrom, provides a further possibility for changing the loading properties of the surface.
  • This second level in combination with the first, enables a wide variety of surface patterns.
  • the choice of the colors of the slat material and its printability open up further possibilities for the design of the surfaces.
  • the high load-bearing capacity of the lamella material 2, 5 must be matched when the slats are attached to the frame.
  • a mechanical pressing 6 of the slats in the frame 1 results in an attachment possibility for low loads.
  • the one-sided gluing 7 of the slats on a surface of the frame 1 is made possible by a shear-resistant gluing.
  • the attachment is achieved by gluing in a groove 8 of the frame 1.
  • the maximum tensile load is calculated at 3500 Newtons (approx. 350 kp). This means that the largest, even selective, loads on the surfaces are possible.

Abstract

L'invention a pour objet des meubles utilisés comme sièges ou appuis dorsaux, du type de construction obtenue en fixant une pluralité de lattes entre un cadre-support. Les lattes sont agencées en plusieurs rangées voisines les unes des autres, de manière à former une surface servant de siège ou d'appui dorsal ou analogue. Lorsque les surfaces sont soumises à une forte charge, le matériau est sollicité sans effort de flexion grâce à une précontrainte des lattes dans le cadre-support. Les lattes sont fixées au cadre de différentes façons en fonction des contraintes requises.
