Definitions

  • the invention relates to a mattress with a two-ply mattress core and Eininkzonen for hip and shoulder area.
  • mattresses with a mattress core with at least two superposed layers of foam with different specific spring strengths known in which one layer forms a softer layer and another layer a harder layer. By turning the mattress, the user can decide if the harder or softer layer is on top. The upper side layer and its hardness or spring strength is decisive for the perceived by the user hardness of the mattress.
  • DE 20207912 U1 moreover discloses a mattress with a mattress core, which is formed by at least first and second plate-shaped, flat superimposed and fixed in this position by a mattress cover combination core, which consist of a material of different hardness compared to each other and on its two flat sides with different Surface profiling are provided which give the two flat sides of a Kombikernes a different degree of hardness, the two combi core optionally with one of their profiled flat side laying on each other and in their down / up position are interchangeable and thus optionally one of four different mattress hardness is adjustable.
  • a mattress core which is formed by at least first and second plate-shaped, flat superimposed and fixed in this position by a mattress cover combination core, which consist of a material of different hardness compared to each other and on its two flat sides with different Surface profiling are provided which give the two flat sides of a Kombikernes a different degree of hardness, the two combi core optionally with one of their profiled flat side laying on each other and in their down / up position are interchange
  • mattresses with softer zones for receiving the hip area and shoulder area of a person lying on the mattress are known.
  • These Eininkzonen have a compared to the specific spring strength of the mattress, which is present in the area outside the Einsinkzonen, reduced spring strength.
  • These zones are often realized by extending over the width of the mattress core molding cuts with material removal.
  • a mattress with a core consisting of PUR foam, cold foam, viscoelastic foam, latex or similar material which receives across the core width extending molding cuts with material removal in the surface to achieve by the thus resulting softer segments a shoulder or basin lowering.
  • In the form cuts are countershapes individually and at any time by the mattress user itself insert or remove, whereby the strength in the different zones can be adjusted individually.
  • DE 202004001574 U1 discloses a mattress with a mattress core adapted for use on a first and a second lying surface, which can be brought into a use position by turning the mattress, the mattress core on both sides over the length of the mattress adjacent zones of different hardness, wherein on both Pages of the mattress core different distributions of hardness zones are formed.
  • the mattress according to the invention initially has a mattress core with at least two superposed layers of foam, for example made of cold foam, latex or visco foam. These layers have different specific spring strengths and therefore give different with an identical load with identical load area. It is the basic spring strength of the situation away from the Einsinkzonen described later. For example, for the softer layer a compression hardness of about 3.5 kPa and for the firmer position a higher compression hardness of about 5 kPa can be set. The spring strength is usually determined by the type of foam, ie material, pore size and pore wall thickness. But it can also be taken other measures, for. B .: cuts and cavities. There are therefore in the mattress core a softer position and a harder position. The expert selects the two specific spring strengths so that a desired range can be achieved by up / down exchange.
  • foam for example made of cold foam, latex or visco foam.
  • the softer and harder layers each have at least two sink marks for receiving the hip area and shoulder area of a person lying on the mattress.
  • third Eininkzonen can be provided in the leg area, which can serve as eininkzone for the shoulder with twisted sleeping position.
  • said first two sinking zones are sufficient.
  • the Einsinkzonen have a reduced compared to the specific spring strength of each layer specific Einsinkzonen spring strength.
  • the specific Eininkzonen spring strengths may differ in the individual layers.
  • the Eininkzonen spring strengths of the shoulder and hip area of each layer can be different sizes. If the leg area has a further Eininkzonen- spring strength, this can serve as an alternative shoulder area, so that further combinations can be achieved by 180 ° rotation of the layers about the vertical axis.
  • the particular feature of the invention is that not only one layer, but both layers each have a top and bottom, in which the Einsinkzonen are only incorporated so that different Eininkzonen spring strengths result, depending on whether you from the top or the Bottom pressure exerts on this.
  • the sinking zones are therefore incorporated into the two layers in such a way that the upper sides in the region of the sinking zones have the said reduced specific sinking spring strength and the undersides in the region of the sinker zones have a mean specific sinking spring strength whose strength lies between the reduced specific sinking zone Spring strength and the specific spring strength of each layer is. Therefore, the Eininkzone a layer is different soft, depending how the situation is. However, it does not change the specific spring strength of the situation away from the Einsinkzonen.
  • An up-down exchange of the layers results in 2 further possibilities, which vary both the top-side total spring strength away from the sink-in zones and the top-side overall degrees of hardness in the area of the sink-in zones. It is therefore with the two inventively designed layers by turning and / or top-bottom exchange 8 variants can be generated.
  • top overall spring strength and “top overall hardness levels in the area of sinking zones” do not refer to a single layer, but to a load from above on the mattress with the layers lying one above the other in the mattress core.
  • the invention presupposes that the sinking zones of the two superimposed layers also lie substantially one above the other.
  • the size of the superimposed sinking zones may also be different, that is, they extend over a different length of the mattress. But there always remains a common zone away from all superimposed sinking zones.
  • the softer and the harder layer each have at least one zone apart and in particular between the sinking zones, which has the specific spring strength of the respective layer.
  • this zone the situation is just as solid as the location would be without any Eininkzone.
  • This zone is therefore as solid on the bottom as on the bottom. The turning of a layer therefore has no influence on the top overall spring strength in the region of these zones away from the sinking zones.
  • the person skilled in the art selects the different specific spring strengths of the layers and the reduced specific spring strengths and mean specific spring strengths of the Einsinkzonen both layers such that by turning the layers and top-bottom Exchanging the layers a total of eight different mattresses are adjustable, with eight different upper-side total degrees of hardness in the area of Einsinkzonen.
  • This selection then allows anatomically different customers from the same few components described here to put together the best mattress for him. He can also adapt the properties later, for example, if his anatomy has changed. In essence, he can fall back on a matrix described later to determine the orthopedic cheapest mattress, the parameters of weight, body size and body shapes, so the weight distribution between shoulder area, abdominal area and hip area.
  • the degrees of hardness are named typical for the branch: H1: soft; H2: middle festival; H3: hard; H4: Very hard.
  • the body size-weight diagram is structured in this way: With the weight, the required degree of firmness increases with the remaining body size. With the body size, the required degree of hardness decreases while the weight remains constant. Example: Long light persons need H1. Short, stout people need H4.
  • the mattress construction according to the invention already allows the production of 8 mattress types with only two different layers.
  • the layers may be inseparable during manufacture, so that the mattress type can not be changed.
  • preference is given to a mattress which can be adapted at any time by the user to his needs, in which the layers can be repeatedly subjected to a top-bottom exchange and a turn by the user of the mattress.
  • a slip resistance is preferably provided, which prevents a horizontal displacement of the layers relative to each other. Otherwise, they may creep over the mattress over time and cause unwanted shape changes.
  • Anti-slip may in particular friction-increasing materials or releasable compounds, eg. B .: be Velcro.
  • the sinking zones of the layers are formed by a plurality of side by side, in particular parallel to one another, over the width of the mattress extending cavities - also called spring pockets. These facilitate a compression, since Foam material can be pressed into these cavities.
  • the upper-side spring strength to make less than the underside spring strength, for example, cavities closer to the top than at the bottom of the layers.
  • the combination possibilities according to the invention have a particularly broad spectrum of body masses and proportions orthopedically advantageous can cover. This was not the case if the volumes were identical. A larger volume can be created by enlarging a cavity or by more cavities. In practice, so cavities are cut out with different cross section.
  • cuts preferably extend from the surface of the top of the sheets toward the cavities, preferably across the entire width of the mattress. This results in topside isolated stripes, the can be pressed independently of each other in the cavities. By this alone, the difference between the top and bottom spring strength can be realized, even in the middle between the top and bottom extending cavities.
  • the cuts ensure that the stripes at least touch and are not completely independently movable, which can lead to holes / steps in the surface.
  • the jounce behavior of the sinking zones that is to say the spring strength as a function of the spring travel, can be influenced.
  • a constant spring force over wide spring distances is obtained with round and square cross sections.
  • Mattress toppers or “toppers” can form the upper end of a mattress. It is a few centimeters thick mat, which is intended to increase sleeping comfort in any lying position and protects the underlying mattress.
  • the topper often consists of sheep's wool, horsehair, cold foam, viscoelastic material or latex and usually a removable for hygienic reasons cover. As a continuous topper he creates a double bed in the double bed.
  • Other mattress variations may be provided if a mattress overlay is provided on the upper of the two plies, both sides of which have different comfort characteristics, preferably one side of viscose foam and the other side of gel foam.
  • the previous 8 variations can therefore be tripled to a total of 24, since preferably the mattress can be provided either with or without the mattress pad by the user and the mattress pad can be selectively connected to one of its two sides on the upper of the two layers.
  • each layer is provided with its own coating, in particular with slip resistance to prevent horizontal slippage of the layers against each other.
  • the coating may act slip-resistant or be designed so that the layers do not slip against each other, for. B .: by means of a thin elastic fleece or net. It can also be a common elastic fleece or mesh are used, which covers all layers, optionally including pad, to make it difficult to shift the layers to each other.
  • a tool-free cover for wrapping and holding the mattress core formed from the layers, the layers are protected and securely held while exchangeable and reversible.
  • the mattress pad can also be wrapped and held by the sheath.
  • the envelope is preferably closed by means of a zipper, in particular circumferentially, so that the envelope can exert pressure on the mattress core.
  • the height of the layers is preferably 6-15 cm, preferably 8-12 cm.
  • the mattress pad has a height of 4 - 8 cm, preferably 5-7 cm.
  • the lengths and widths correspond to the usual mattress dimensions. The length is therefore preferably 1.9 - 2.1 m, the width 0.8 - 1.8 m.
  • Fig. 1 shows the schematic structure of the mattress 100 according to the invention with a mattress core 10.
  • This has two superposed layers H, W made of foam. These have different specific spring strengths, which are formed here by the different compression hardness of the materials. Therefore forms in Fig. 1 the upper layer the softer layer W and the lower layer a harder layer H.
  • Both superposed layers H, W each have two different sinking zones ZH, ZW (left and middle position) for receiving the hip area and shoulder area of a person lying on the mattress.
  • the right sinking zones reflect the respective right shoulder zone so that the foot and head ends of the mattress are interchangeable. Bags or incisions ensure that the sinking zones ZH, ZW have a specific Eininkzonen-spring strength reduced in comparison to the specific spring strength of the respective layer H, W.
  • the Eininkzonen recording of the hip area and shoulder area may have different spring strengths and be designed differently, but fall under the following conditions:
  • Fig. 1 further shows that the two layers each have a top OH, OW and bottom UH, UW.
  • the Eininkzonen ZH, ZW are so incorporated into the two layers H, W that by turning the spring strength changes against a load from above: For this, have the upper sides OH, OW in the sinking zones on the reduced specific Einsinkzonen spring strength and Bottom sides UW, UH in the area of Einsinkzonen a medium specific Eininkzonen pen strength, the strength between the reduced specific Einsinkzonen spring strength and the specific spring strength of the respective layer.
  • the pockets or incisions of the sinking zones point downwards so that the sinking zones are less soft.
  • the incisions are upward, the strips formed by the cuts can spring in more independently and therefore more easily.
  • the lower layer H which by reversing allows a further influencing of the overlying Einsinkzone ZW, without affecting the overall hardness of the mattress. This is rather influenced by top-bottom exchange of the two layers H, W.
  • the sink-in zones ZH of the lower layer H point downwards, so that the overall result is a low degree of softness of the mattresses in the region of the sink-in zones.
  • a wrapper 20 holds the two plies H, W together. Thereupon lies the mattress pad 30, one side 31 of viscose foam and the other side of gel foam 32.
  • Fig. 2 shows the matrix of the possible combinations of the two reversible and top-down exchangeable layers H, W according to the invention.
  • the total hardness of the mattress is achieved by top-bottom replacement of the two layers. With the same configuration, this replacement causes a change in the degrees of hardness from H1 to H3 or from H2 to H4.
