Definitions

  • the invention relates to a mattress with a core made of elastic material.
  • a spring mattress is a complex form of mattress, in which the elastic core is formed by spiral springs of different thicknesses. In an even more complex version, the coil springs are accommodated in individual pockets.
  • the core is also known to form the core from a uniform elastic material, for example from a latex.
  • a common base for mattresses are slatted frames, the spring slats of which are also designed to achieve the healthiest possible resting position with different spring hardnesses can.
  • the spring slats of which are also designed to achieve the healthiest possible resting position with different spring hardnesses can.
  • curved wooden slats are used, the spring hardness of which can be adjusted by the width and / or thickness of the slats or by variable lateral clamping.
  • the aim of the present invention is therefore to provide a mattress structure with which different spring hardnesses can be achieved without the formation of cold bridges and which leads to a mattress which is particularly suitable for adjusting the mattress topper.
  • a mattress with a core made of elastic material is characterized in that the elastic material is arranged in several layers and is formed with numerous corrugations in each of the layers, which lead to the formation of air gaps.
  • the mattress according to the invention is made up of layers which are shaped according to the accordion principle and can easily be changed in length due to the corrugations. The change in the length of this elastic material leads to a change in the resulting spring hardness.
  • the corrugations can preferably be designed such that when the material is compressed transversely to the corrugations, the spacing of the corrugations is reduced substantially uniformly.
  • the material for the layers is preferably a foam, which is cut to the appropriate shape with the corrugations. It is expedient for the mattress if the elastic material in the mattress is prestressed transversely to the corrugations in the sense of a compression. The layers of material thus have a tendency to increase the length of the mattress to achieve the initial length that was present when the layers were made. It is readily apparent that such a pre-tensioned mattress has a bend leading to a
  • the mattress layers therefore preferably have a degree of pretension such that the elastic material is not subjected to tensile stress when the mattress is adjusted in the usual way. In the event of a train load, this would only be possible against an elastic restoring force.
  • the design according to the invention prevents the strain on the train, and thus the creation of restoring forces.
  • the mattress structure according to the invention also allows the spring characteristics to be set in that at least two different spring hardnesses are formed in the several layers of the elastic material.
  • This spring hardness can in particular be formed by compressions of different strengths. If the mattress has local compressions of different strengths in the direction transverse to the corrugations, different spring hardnesses are set in the direction transverse to the corrugations, that is to say regularly in the direction of the length of the mattress. This setting is readily possible from a starting material and can generally be changed again without any problems.
  • a desired zone distribution for example with different spring hardness, can be achieved by attaching strips, which are aligned parallel to the corrugations, on the underside of the mattress and can be inserted into the interstices of a slatted frame.
  • the distribution of the strip spacing can be selected accordingly to form the desired local upsets.
  • the mattress according to the invention can be constructed with a relatively small thickness and allows a high level of comfort.
  • the formation with at least three layers of the elastic material is preferred, the three layers preferably being formed with 0 different spring hardnesses.
  • the resulting air gaps are preferably approximately triangular in shape, so that the straight-line connectors on the underside of the web forming the bearing surface are pointed together.
  • Figure 1 schematically shows a mattress with three layers in the un-compressed state and in differently strong compression states
  • FIG. 2 shows a mattress according to FIG. 1 on a straight support and the mattress after a step-like deformation
  • FIG. 3 shows a mattress with strips attached to the underside in the initial state, in a compressed state, in a compressed state and mounted on a slatted frame with hydraulic cylinders, and in the assembled state under the load of a person lying down
  • FIG. 4 shows a representation according to FIG. 3 with strips which are arranged at irregular intervals and which lead to the formation of locally different compressions during assembly
  • Figure 5 is a mattress formed by locally different compressions with different spring hardness zones, consisting of six layers
  • FIG. 6 shows a mattress according to FIG. 5, in which an inelastic insert which is inelastic in the longitudinal direction of the mattress is inserted between three upper and three lower layers and is connected to the adjacent layers for maintaining shape
  • FIG. 7 shows a mattress placed on an adjustable base without adjustment and after adjustment in a reclining-sitting position
  • FIG. 8 shows a spring characteristic field for three layers with different spring hardnesses with different load weights.
  • Figure 9 - a spring characteristic field for three layers with different spring hardness with different degrees of compression of the mattress.
  • Figure 1 illustrates the basic structure of a mattress according to the invention, which consists of three layers L1, L2, L3.
  • the layers in the top line in FIG. 1 are shown as they are formed by cutting.
  • Each layer has corrugations 1 formed transversely to the longitudinal direction, which form an upper flat support surface 2 and a lower flat support surface 3 in the illustrated embodiment.
  • An obliquely extending connecting web 4 is arranged between the two contact surfaces 2, 3.
  • a triangular air gap 5 is formed between each two connecting webs 4.
  • the layers L1, L2, L3 can be connected to one another in that bearing surfaces 2, 3 that come into contact with one another are glued together.
  • the first layers L1, L2, L3 have their original length (100%).
  • the mattresses shown below are shown in the compressed state, namely compressed to 90%, 80%, 70%, 60% and 50% of the original length. This results in an inversely proportional spring hardness, which when compressed to 50% of the original length is twice as large as the spring hardness in the non-compressed state.
  • FIG. 2 shows in line a a mattress made of the material according to FIG. 1 by forming a suitable degree of compression and lying on a flat surface.
  • a bulge of the mattress is shown below, which is caused, for example, by the fact that a slatted frame on which the mattress lies under the load of a person lying down yields below.
  • Figure 2b illustrates that enters into the step-like transitions Ü a 'increase in length in the layers Ll, L2, L3, which leads into the transition regions Ü to a "Entstauchung" of the layers Ll, L2, L3.
  • the * - * corresponding bulge of the mattress is therefore not counteracted by the mattress, rather the bulge is rather supported due to the pre-tension in the mattress.
  • the mattress shown is therefore particularly suitable for practically following such bulges on a base of the mattress 10 without restoring forces.
  • FIG. 3 shows an exemplary embodiment of a mattress which is provided on its underside with strips 6 running parallel to the corrugations 1.
  • the strips 6 are at the same distance from one another.
  • Line b shows a compressed condition of the mattress, in which the distances between the strips 6 have been reduced evenly. The distance has been reduced so that the strips can be clamped in the space between two tubes forming a pair.
  • the tubes 7 of each pair are connected in the middle to a hydraulic cylinder 8.
  • Line c of Figure 3 shows the assembled state in which the compression of the mattress is automatically maintained due to the clamped strips 6.
  • Line d of Figure 3 shows the assembled arrangement according to line c. '• • j in the loaded state, for example in the supine position of a
  • FIG. 4 shows an embodiment which essentially corresponds to the embodiment of FIG. 3.
  • the strips are spaced unevenly.
  • the strips 6 are aligned equidistantly, so that zones ZI to Z6 of different degrees of compression, that is to say of different levels of spring hardness, are illustrated in the mattress - as illustrated in FIG. 1 is - arise. If the compression distribution is matched to the burdening person, the depth of penetration of the person over the entire length of the body is largely the same, which subjectively increases the "comfort" of lying down.
  • FIG. 5 shows a mattress consisting of six layers L1 to L6, which is designed for use without a flexible underlay. It essentially has five zones ZI, Z2, Z3, Z4, Z5, through which different depths of penetration of the lying person P can be realized, as the stressed state in FIG. 5 shows.
  • FIG. 6 shows a variant of the mattress according to FIG. 5, in which a fabric layer G is inserted between the three upper layers L1 to L3 and the three lower layers L4 to L6 and connected, for example glued, to the adjacent layers L3, L4 in order to in this way to maintain the different local upsets for zones ZI to Z5 and to prevent a compensation of the upsets across zones ZI to Z5.
  • a fabric layer G is inserted between the three upper layers L1 to L3 and the three lower layers L4 to L6 and connected, for example glued, to the adjacent layers L3, L4 in order to in this way to maintain the different local upsets for zones ZI to Z5 and to prevent a compensation of the upsets across zones ZI to Z5.
  • FIG. 7 shows an articulated adjustable support U with segments U1, U2, U3, U4, U5, which are connected to one another via rotary joints D1, D2, D3, D4.
  • the swivel joints are mounted approximately at the top or bottom of the mattress so that the usual adjustment of the segments U1 to U5, as shown in line b of FIG. 7, always extends the positions L1 to L6 of the mattress ren, and not - as usual and disadvantageous - to a shortening.
  • the mattress according to the invention which consists of compressed accordion-like layers L1 to L6, is particularly suitable for such a support U because it can follow the deformations without restoring forces.
  • FIG. 8 illustrates characteristic curves of a mattress with three layers L1, L2, L3, of which the top layer L1 has a small spring hardness, the middle layer L2 has a medium spring hardness and the bottom layer L3 has a high spring hardness.
  • a pressure exerted by a person lying down therefore leads to a relatively strong deformation in position L1, plotted as a path in FIG.
  • the slope of the deformation as a function of the pressure becomes smaller for the middle layer L2 and again considerably flatter for the lower layer L3.
  • the six plotted curves 11, 12, 13, 14, 15 show curves for increasing hardness of the starting materials of the mattress when subjected to a person.
  • FIG. 9 shows spring characteristics of a mattress with three layers L1, L2, L3 with different degrees of compression of the mattress.
  • Curve 11 ' corresponds to the un-compressed material and, as the initial curve, corresponds to curve 12 in FIG. 8.
  • Curves 12' to 16 ' show changes in hardness due to increasing compression of the starting material according to curve 12 in FIGS. 8 and 11' in FIG. 9.
  • the differently sized spring hardnesses can be adjusted in the longitudinal direction within the mattress according to the load profile of a person, whereby different contact pressures for legs, trunk and head have to be taken into account.
  • this slatted frame already ensures the complete contour adaptation to the person.
  • the mattress only "forms the comfortable support and should correspond to that Load profile, i.e. the pressure distribution of the person in the longitudinal direction, be designed or pre-compressed.
  • a subjectively constant hardness of the mattress in the longitudinal direction is created for the person and an almost constant depth of impression is achieved in the mattress, thereby increasing the comfort and durability of the mattress.
  • the mattress would be designed in the leg area, that is to say for a low contact pressure, without compression, that is, according to curve 11 ', in the torso area with a large compression, that is, corresponding to curve 16'.
  • the mattress also has the advantage that it can follow a resilient mattress topper without any restoring forces and is therefore particularly suitable for highly developed slatted frame systems that react to local loads to form a lying position that is as healthy as possible.
