Definitions

  • the present invention relates to a device for variable reinforcement of the elastic support forces in any partial areas of reclining furniture with spring bars arranged transversely to the reclining furniture axis, for the purpose of improving the load-bearing behavior while simultaneously reducing the space between the female and male bars in the areas of greatest load.
  • the known reclining furniture provided with transverse spring slats which are also referred to as LSUtlicbuch, have an elastically deformable lying surface that bends depending on the local load and intercepts the load with a corresponding support force opposing the load.
  • This elastic reactivity of the bed surface which is sometimes also referred to as spring hardness, is now the same size in the known bed furniture over the entire bed surface, although the load on the bed surface is undoubtedly very different locally.
  • the greatest load generally occurs in the central area of the lying surface, ie at the support points of the buttocks and hips, while the end areas support the head and feet are hardly subject to noteworthy loads.
  • people can change their body weight considerably over time and that the load conditions of a bed are subject to considerable fluctuations, for example after an emaciation regimen or during pregnancy.
  • the object of the present invention to provide a device for zone reinforcement on reclining furniture with spring slats, which allows any zones of the lying surface, but in particular the most stressed middle zone, to be varied at will with regard to their elastic supporting force, in order to thus prevail To be able to adapt stress conditions in the sense of physiologically correct lying.
  • the device should not require any damage to the adjacent female connectors for its attachment and, moreover, should bring the additional advantage that it contributes to the protection of the top mattress and its better carrying behavior.
  • Fig. 1 shows a slatted frame designated in its entirety with 1, which is composed of two longitudinal frames 2 and a number of transverse spring slats 3.
  • the female connectors 3 are designed in a known manner as multi-layer wooden springs and are based on rubber-elastic support bodies 4, which are anchored to the inner surfaces of the longitudinal frames 2. On each pair of these support bodies 4, as the figure shows, there are two spring strips 3 which are arranged at a mutual distance and are thus assigned to the support bodies in pairs. Details . this construction results from the CH patent application No. 12002/77.
  • a known central belt M is arranged in the central region of the slatted frame.
  • the mutually adjacent pairs of female connectors 3 are at a mutual distance a.
  • This distance must be chosen to be relatively large for wooden spring gratings, because if the pitch is too narrow, the spring hardness would be exceptionally high.
  • the waiter, not shown mattress is pressed with its underside into the space between adjacent pairs of female connectors and there is prematurely worn or damaged under the influence of sleep movements. Correcting this deficiency is one of the objects that the present invention is intended to solve.
  • this device comprises two rubber-elastic coupling members 5 and an additional spring slat Z.
  • the coupling member 5 is a profile body which has two longitudinal strips 6/7, which are connected to one another by transverse webs 8, 9. In this way, there is a through opening 10 in the central region and an open recess 11/12 at each of the two ends.
  • the height h of these recesses corresponds approximately to the thickness of the wooden spring slats 3 (FIG. 3), so that the coupling element 5 can be arranged like a bridge between two pairs of wooden spring strips 3 and secured with the recesses 11, 12 on the adjacent wooden spring strips.
  • the two retaining lips 13 and 14 delimiting the recesses are of different lengths (compare length difference d in FIG.
  • the recess can be installed 11 over a wooden female connector and then snap the coupling element from above with the shorter lip 14 over the other wooden female connector.
  • the coupling element which should consist of a tough, rubber-elastic material with high flexural strength, is thus securely anchored in the space between two pairs of wooden slats.
  • the through opening 10 is dimensioned such that the additional spring slat designated Z in FIG. 1 can just be inserted through the opening and is then held firmly in the same.
  • the inner walls of the through opening 10 are preferably narrowed slightly on one side or on both sides, as is shown in particular in FIG. 4.
  • the webs 8 and 9 are slightly cambered on the contact surfaces F on the additional spring slat Z in the exemplary embodiment.
  • the device will accordingly be fitted with any number of additional spring slats Z in the area of the heaviest load and its elastic behavior can be adapted to individual needs by regulating the distance c. Since the additional spring slats Z are anchored to the spring strips 3 via the coupling members 5, the suspension properties of the latter will also change.
  • the entire support area B (FIG. 1) can thus be "hardened", while individual areas within this area can either be made particularly hard or more resilient.
  • rubber-elastic used in the present context is to be understood to include all materials, in particular also plastics, which can be compared to rubber on account of their elasticity behavior.
  • the rubber elasticity based on the material itself is therefore the formula elasticity, e.g. a coil spring, opposite.
