Definitions

  • the present invention relates to a device for variable reinforcement of the elastic support forces in any partial areas of a reclining furniture slatted frame with spring bars oriented transversely to its longitudinal axis and each with spring bars mounted at the end on longitudinal frames, comprising at least between two adjacent spring bars which can be attached essentially in the direction of the longitudinal axis, which coupling elements bridge the respective bar spacing (DE-B-2 756 477).
  • the known reclining furniture provided with transverse spring slats which are also referred to as LSUtlicouch, 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 lying surface which is sometimes also referred to as spring hardness, is now the same size in the known lying furniture over the entire lying surface, although the load on the lying surface is undoubtedly very different locally.
  • the greatest load is generally in the central area of the bed, i.e. H. at the buttocks and hip support points, while the end areas for supporting the head and feet are hardly subjected to any 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 device should also require no damage to the adjacent spring slats for its attachment and also bring with it 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.
  • 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.
  • due to the large distance a there is a risk that the underside of the top mattress, not shown, will be pressed into the space between adjacent pairs of spring slats, where it will be worn or damaged prematurely 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 elements 5 and an additional spring slat Z.
  • the coupling element 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 is arranged in the manner of a bridge between two pairs of wooden spring slats 3 and with the off Secures 11, 12 can be secured to the adjacent wooden slats.
  • the two retaining webs 13 and 14 With a view to simple handling during installation and removal, the two retaining webs 13 and 14 (FIG.
  • delimiting the recesses are of different lengths (compare length difference d in FIG. 3), but in any case shorter than the overall width of a female connector 3 During assembly, it is thus possible, for example, to insert the recess 11 over a wooden spring strip and then to snap the coupling element from above with the shorter webs 14 over the other wooden spring strip.
  • 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 be pushed 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.
  • any number of additional spring slats Z will accordingly be attached in the area of the heaviest load and their elastic behavior will 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 elements 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 flexible.
  • 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 due to their elasticity behavior.
  • the rubber elasticity based on the material itself is the formula elasticity, z. B. a coil spring opposite.
