Definitions

  • the invention relates to a mattress with at least one layer which has a large number of elastic elevations. These elastic elevations together form at least one support surface for the user of the mattress.
  • Mattresses which are usually made of foam plastics, are available in a wide variety of versions in the prior art. Designs have also become known in which the support surface is formed from smaller partial areas, which are provided, for example, by individual foam elements.
  • DE-OS 1554130 a mattress (base or topper for the human body) in which foam or foam rubber sections are inserted into a grid-like support. The parts of these sections that protrude beyond this support then together form the support surface of the mattress.
  • the DE 29701959 U1 shows a mattress in which contiguous cube elements are formed from a support layer by cutting. These cube elements are rounded off in a pyramid shape on their top.
  • the present invention focuses on a completely different aspect compared to the prior art.
  • the primary aim is not to enable comfortable and ideally orthopedically healthy resting and lying on the mattress. Rather, human evolution should be taken into account when developing a new mattress. So the question is: Which resting or lying positions do people actually meet their physical needs? Which resting and lying positions are actually “species-appropriate” and “healthy”?
  • the invention is intended to provide a mattress that enables people to actually rest or sleep in a relaxed manner.
  • the actual support surface of the mattress should take human evolution into account and thus enable original lying positions to be assumed on the mattress that have been forgotten over long periods of time.
  • the new mattress should enable the user to (re)give the user the feeling of rest and sleep on a soft forest floor.
  • the new mattress includes at least one layer that has a plurality of elastic elevations. These elastic elevations together form at least one support surface for at least part of the body of a user of the mattress.
  • the elastic elevations are designed or arranged in such a way that an uneven support surface is formed.
  • the term “mattress” is intended to encompass all cushions and cushioning elements that are provided in basically any size as a support or base, in particular for the human body or part of it, for example for lying or sitting.
  • the term “elastic elevation” is intended to mean that individual sections or areas are provided which have elasticity and accordingly deform under the influence of force (resting on the body) and return to the original shape after this force is removed. A large number of such elastic sections or areas then together form the support surface of the mattress.
  • an uneven support surface is formed with the help of the elastic elevations. “Uneven” means that different places/areas of the support surface have different heights, in contrast to a flat support surface. Preferably, the unevenness in the invention does not follow a regular pattern, but the points/areas of different heights are distributed irregularly over the support surface.
  • the non-flat support surface can be provided on the one hand by appropriately designing the corresponding elastic sections and areas. For example, elevations of different heights can be provided.
  • an uneven support surface can also be provided, for example, by arranging elevations differently to form the layer.
  • the elastic elevations are formed on individual elastic bodies.
  • Each elastic body preferably provides an elastic elevation.
  • the elastic elevation can be formed by (at least) one side surface of this cuboid/cube.
  • the individual elastic bodies with the elastic elevations formed on them are inserted into the openings (meshes) of a planar grid.
  • a closed connection is provided between the individual elastic bodies, and on the other hand, a ventilation function can be provided by the appropriate construction of the grid.
  • At least two types of elastic elevations with different elasticity are provided. In this way it can be achieved that a different hardness of the supporting surface is provided in different areas of the uneven supporting surface.
  • the support surface provided by the elastic elevations is not only uneven, but also has different elasticity/hardness.
  • the elastic elevations and in particular the elastic bodies on which the elastic elevations are formed, can consist of a wide variety of natural or artificially produced materials. It is preferred if plastics, in particular foamed plastics, are used, with the use of at least one polyurethane foam being particularly preferred in this context.
  • rigid foam plastics are foams that offer a relatively high resistance to deformation under pressure. This is due, among other things, to the fact that rigid foams are predominantly closed-cell. In contrast, the (softer) soft foam plastics usually have an open-cell structure. If rigid foam plastics are to be used according to the invention, polyurethane (PUR/PIR) foams or polystyrene (PS) foams should be mentioned in particular.
  • PUR/PIR polyurethane
  • PS polystyrene
  • PUR foams are used in particular as soft foam plastics that can be used according to the invention. As is well known, these are made from isocyanates and polyether polyols, using open-cell crosslinking. These can also be polyurethane (PUR) composite foams, which usually consist of cuttings from PUR soft foam production and at least one binder.
  • the elastic bodies with the elastic elevations to form the uneven support surface of the mattress have different dimensions. So the elastic bodies, in particular the polyhedra described below, can have different heights. With the help of these different dimensions, in particular different heights, it is then possible to provide an uneven support surface.
  • the support surface as a whole then consists of only two types of elastic bodies with different dimensions, whereby if necessary and preferably these different elastic bodies can also have different elasticity.
  • the elastic bodies preferably have the shape of a polyhedron.
  • a polyhedron is a body that is bounded exclusively by straight surfaces (planes).
  • these straight surfaces (planes) can then serve as an elastic elevation in order to provide a corresponding section or area for the uneven support surface.
  • the elastic bodies in the invention have the shape of a cuboid or a cube.
  • the elastic bodies preferably have dimensions (edge lengths for polyhedra) of less than 20 cm, with dimensions between 1 cm and 15 cm being preferred. Within the last-mentioned range, dimensions between 2 cm and 10 cm, in particular between 5 cm and 8 cm, are further preferred.
  • the dimensions a and b are preferably between 5 cm and 7 cm, and the dimension c is between 3 cm and 8 cm.
  • the support surface is then formed from these four types of elastic bodies (cuboids).
  • the feature of an uneven support surface is fulfilled if at least one elastic elevation or one elastic section/area differs from the other elevations/sections/areas, in particular in height.
  • the corresponding unevenness should be distributed over the entire contact surface. In principle, this can be achieved by distributing the elevations, in particular the arrangement of elastic bodies with different dimensions, in a regular pattern over the entire support surface. This regular pattern can be predetermined and then results in a corresponding arrangement of the elevations or in a regular arrangement of the elastic bodies on which the corresponding elevations are located.
  • the "unevenness" of the support surface does not follow a specific (predetermined) pattern. Rather, in preferred embodiments of the mattress according to the invention, the elastic elevations, and thus in particular the elastic bodies, are irregular, ie distributed over the support surface without a predetermined pattern. This is consistent with what was stated at the beginning The image used shows that the mattress according to the invention should give the user the feeling of resting or sleeping on a (soft) forest floor. Although such a forest floor is ultimately uneven (like the mattress according to the invention), these unevennesses are (also) not distributed in a regular pattern over the support surface for the user.
  • the cross-sectional area which may be defined by the dimensions a and b of the cuboid or cube-shaped elastic bodies, is slightly larger than the mesh size of the net, so that reliable clamping of the elastic bodies in the grid is guaranteed.
  • (small) cavities are created between adjacent elastic bodies, which ensure uniform, internal ventilation and enable the release of moisture and heat.
  • the elastic elevations and in particular the elastic bodies according to the invention preferably consist of foam plastic.
  • Various parameters such as density (also called density) or compression hardness can be used to determine the relative strength of foam materials (hardness/softness).
  • density also called density
  • compression hardness can be used to determine the relative strength of foam materials (hardness/softness).
  • density density
  • compression hardness is given in kPa. It tells you how much pressure has to be applied to a foam in order to compress it to a certain percentage of its original height.
  • the foam plastic used has a compression hardness (at 40%) of ⁇ 20 kPa, in particular a compression hardness (at 40%) of ⁇ 10 kPa.
  • Preferred bulk densities of the foam plastics that can be used according to the invention are between 30 kg/m 3 and 80 kg/m 3 , in particular between 40 kg/m 3 and 50 kg/m 3 .
  • the mattress has at least one base underneath the at least one layer with the elastic elevations. This at least one base gives the layer and thus the mattress according to the invention additional stability.
  • the base is usually connected to the layer arranged above it, in particular glued. If the elastic elevations are located on elastic bodies, these bodies can be connected, in particular glued, to the base on their underside (facing away from the elastic elevations). In preferred embodiments, it may be sufficient if this connection, in particular gluing, is only provided on the elastic bodies provided on the edges of the mattress.
  • the base mentioned is preferably designed in one layer. It preferably also consists of a foam plastic, as is also used for the elastic elevations themselves or the elastic bodies.
  • the base can preferably consist of a foam plastic with lower elasticity, as is used for the elastic bodies described with greater hardness.
  • the mattress according to the invention which can basically be manufactured in any size (for example as a seat cushion and the like), preferably has the dimensions of so-called standard mattresses.
  • Common sizes for single beds for example, are 100 cm x 200 cm and 90 cm x 200 cm.
  • the height of the mattress according to the invention is generally in the range of the heights of standard mattresses, i.e. between 15 cm and 25 cm.
  • the height of the mattress according to the invention is preferably between 15 cm and 20 cm.
  • the layer with the large number of elastic elevations in the mattress according to the invention can have a height of between 5 cm and 10 cm, possibly with a base with a height of between 5 cm and 15 cm, in particular between 8 cm and 13 cm.
  • the mattress according to the invention is designed in such a way that it can be rolled up due to the materials used. This makes transporting the mattress easier, for example.
  • the mattress according to the invention can in particular only have one (thin) cover, which, on the one hand, protects the uneven support surface against dirt and wear and, on the other hand, at least partially absorbs the moisture formed when resting or sleeping.
  • a thin cover can also have a warming and/or anti-allergic function.
  • the user of the mattress is given a completely new feeling of rest and sleep.
  • the feeling of comfortably sinking into a mattress with a flat surface may be missing.
  • this feeling is quickly replaced by the impression that the mattress according to the invention provides a completely new feeling of lying on that supports the body. Every movement on the mattress has a massaging and revitalizing effect.
  • Fig. 1 shows a grid (11) with fibers (12) arranged in the longitudinal and transverse directions. Openings (13) are formed between the fibers arranged in three rows. As will be explained later, these openings serve to accommodate elastic bodies.
  • the example uses PVC-coated polyester fibers.
  • the arrangement in three rows serves to provide a ventilation effect for a layer according to the invention.
  • the dimensions of the grid (11) in the example are 60 cm x 60 cm. Correspondingly larger grids are used for (full-body) mattresses with the sizes mentioned above.
  • Fig. 2 shows four different elastic bodies 21, 22, 23 and 24 in cuboid shape, which are used with the help of the grid (11) to produce a layer according to the invention and a mattress according to the invention.
  • the elastic bodies 21 to 24 are made of polyurethane foam.
  • the elastic bodies 21 and 22 consist of a harder foam, ie a foam lower elasticity, and the elastic moldings 23 and 24 consist of a softer foam, ie a foam of greater elasticity.
  • the elastic bodies 21 and 22 can consist of a polyurethane foam with a bulk density of 44 kg/m 3 and a compression hardness of 6.5 kPa
  • the elastic bodies 23 and 24 can consist of a polyurethane foam with a bulk density of 47 kg/m 3 and a compression hardness of 4.4 kPa.
  • the compression hardness is based on a compression of 40%.
  • the elastic bodies 21 to 24 are fitted with the grid measuring 60 cm x 60 cm Fig. 1 used.
  • the base area of these cuboid elastic bodies is each 5 cm x 5 cm. These dimensions of the base area of the cuboids 21 to 24 are therefore the same for all elastic bodies.
  • both the harder cuboids 21 and 22 and the softer cuboids 23 and 24 are provided at two different heights. In the example, these heights are 6 cm (cuboids 21 and 23) or 8 cm (cuboids 22 and 24).
  • a layer according to the invention and a mattress according to the invention can be provided with the elastic bodies 21 to 24, in which the support surface is both uneven and has a different hardness at different points.
  • FIGS. 3 and 4 show a layer (31) according to the invention in a schematic top view ( Fig. 3 ) and in a schematic side view ( Fig. 4 ).
  • the elastic bodies 21 to 24 are inserted into the openings (13) of the grid (11), flush on the underside. This can be achieved simply by pressing together and arranging the elastic bodies in the grid accordingly. This will be what both come from Fig. 3 as well as out Fig. 4 can be clearly seen, on the top of the layer (31) there is an uneven support surface with different hardness in different places (not marked in the figures), for example provided for the human body.
  • the elastic elevations which together form the support surface for the user of the mattress, are formed by/on the elastic bodies 21 to 24, in particular by the tops/upper regions of these elastic bodies.
  • Characteristic of the layer (31) according to the invention according to Figures 3 and 4 is, on the one hand, the unevenness of the support surface provided by the elastic bodies 21 to 24, and on the other hand, the different hardness of this support surface at different points/areas.
  • the 5 and 6 show the case in which the layer (31) according to the invention is arranged on a base (52).
  • This base (52) gives the layer (31) additional stability.
  • the base (52) is also made of a polyurethane foam.
  • the base (52) is preferably formed from the same materials as those used for the elastic bodies 21 to 24.
  • the base (52) also consists of a harder foam like the cuboids 21 and 22.
  • the layer (31) can according to Figures 5 and 6 be connected to the base (52) in a suitable manner, in particular by gluing. Here it will usually be sufficient if the edge cuboids of the layer (31) are glued to the base (52) on their underside (over their entire surface).
  • FIGS 7 and 8 finally show the (finished) mattress (71) according to the invention with a cover (72).
  • the cover (72) can be removed using the zipper (73).
  • both figures show that the top of the mattress, which forms the support surface, is uneven. This important aspect distinguishes the mattress (71) according to the invention from previously known mattresses and toppers. In addition, the support surface has different hardness at different points, which represents another important aspect of the invention.
  • the cover can have a thickness of (only) 3 mm with a weight per square meter (grammage) of 300 g/m 2 .
