Definitions

  • the invention relates to a mattress with a two-layer mattress core and sink-in zones for the hip and shoulder area.
  • DE 20207912 U1 also discloses a mattress with a mattress core, which is formed by at least first and second plate-shaped, flat on top of each other and fixed in this position by a mattress cover combination cores, which are made of a material of different hardness compared to each other and on their two flat sides with different Surface profiles are provided, which give the two flat sides of a combination core a different degree of hardness, whereby the two combination cores can optionally be placed one on top of the other with one of their profiled flat sides and interchangeable in their bottom / top position and thus optionally one of four different mattress firmnesses can be set.
  • mattresses with softer zones for receiving the hip area and shoulder area of a person lying on the mattress are known.
  • These sink-in zones have a reduced spring strength compared to the specific spring strength of the mattress, which is present in the area outside the sink-in zones.
  • These zones are often realized by means of shaped cuts running across the width of the mattress core with material removal.
  • DE 20212460 U1 A mattress with a core made of PUR foam, cold foam, viscoelastic foam, latex or similar material, which is shaped across the width of the core with material removal in the surface in order to achieve a shoulder or pelvic lowering through the resulting softer segments.
  • Counter-shapes are custom-made in the shaped cuts and at any time by the mattress user himself to insert or remove, whereby the strength can be individually adjusted in the different zones.
  • DE 202004001574 U1 discloses a mattress with a mattress core, designed for use on a first and a second lying surface, which can be brought into a position of use by turning the mattress, the mattress core having zones of different hardness adjoining one another on both sides over the length of the mattress, on both Different distributions of the hardness zones are formed on the sides of the mattress core.
  • US 2018/008050 A1 discloses a mattress with a mattress core with at least two superimposed layers of foam with different specific spring strengths, so that one layer forms a softer layer and the other layer forms a harder layer.
  • the mattress according to the invention initially has a mattress core with at least two layers of foam, for example of cold foam, latex or visco foam, lying on top of one another. These layers have different specific spring strengths and therefore yield differently under an identical load with an identical load surface. This is the basic spring strength of the position away from the sink-in zones described later. For example, a compression hardness of approx. 3.5 kPa can be set for the softer layer and a higher compression hardness of approx. 5 kPa for the firmer layer.
  • the spring strength is usually determined by the type of foam, i.e. material, pore size and pore wall thickness. However, other measures can also be taken, e.g. E.g .: cuts and cavities. There are therefore a softer layer and a harder layer in the mattress core.
  • the person skilled in the art selects the two specific spring strengths in such a way that a desired range can be achieved through an upper / lower exchange.
  • the softer and the harder layer each have at least two sink-in zones to accommodate the hip area and shoulder area of a person lying on the mattress.
  • third sinking zones can also be provided in the leg area, which can serve as sinking zones for the shoulder when the sleeping position is twisted.
  • said two sink-in zones are initially sufficient.
  • the sinking zones have a specific sinking zone spring strength that is reduced compared to the specific spring strength of the respective layer.
  • the specific sinking zone spring strengths can differ for the individual layers.
  • the spring strengths of the shoulder and hip areas of the respective position can be of different sizes. If the leg area has a further sinking-in zone spring strength, this can serve as an alternative shoulder area, so that further combinations can be achieved by rotating the layers by 180 ° around the vertical axis.
  • the specialty is that not only one layer, but both layers each have a top and bottom, in which the sinking zones are only incorporated in such a way that different sinking zone spring strengths result, depending on whether you are from the top or the bottom Putting pressure on them.
  • the sinking zones are therefore worked into the two layers in such a way that the upper sides in the area of the sinking zones have the said reduced specific sinking zone spring strength and, however, the lower sides in the area of the sinking zones have a mean specific sinking zone spring strength, the strength of which lies between the reduced specific sinking zone spring strength. Spring strength and the specific spring strength of the respective position. Therefore the sinking zone of a layer is differently soft, depending on how around the layer lies.
  • 2 x 2 4 possibilities to vary the total degrees of hardness on the top in the area of the sinking-in zones, with the same total spring strength of the mattress on the upper side away from the sinking-in zones.
  • total spring strength on the top side and “total degrees of hardness on the top side in the area of the sinking-in 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 naturally assumes that the sinking zones of the two layers lying one above the other also lie essentially one above the other.
  • the size of the superimposed sink-in zones can also be different, that is to say extend over a different length of the mattress. However, there always remains a common zone away from all sinking zones lying one above the other.
  • the softer and the harder layer each have at least one zone away from and in particular between the sink-in zones, which has the specific spring strength of the respective layer.
  • this zone the position is just as fixed as the position would be without any sinking zone.
  • This zone is therefore just as solid on the underside as on the underside. Turning a layer in the area of these zones away from the sinking-in zones therefore has no effect on the total spring strength on the top side.
  • the person skilled in the art selects the different specific spring strengths of the layers as well as the reduced specific spring strengths and mean specific spring strengths of the sinking zones of both layers in order to cover a desired weight, body shape and comfort range in such a way that by turning the layers and above-below Changing the layers, a total of eight different mattresses can be set, with eight different degrees of total hardness on the top in the area of the sink-in zones.
  • the degrees of hardness are named according to the branch: H1: soft; H2: medium strength; H3: solid; H4: Very firm.
  • the height-weight diagram is structured as follows: With the weight, the required degree of hardness increases with the remaining height. With the body size, the required degree of hardness falls while the weight remains. Example: Long, light people need H1. Short, diverent people need H4.
  • the mattress structure according to the invention allows the production of 8 types of mattresses with just two different layers.
  • the layers can be inseparably connected during manufacture so that the mattress type can no longer be changed.
  • preference is given to a mattress which the user can adapt to his needs at any time, in which the layers can be subjected to an upper-lower exchange and a turning several times by the user of the mattress.
  • a layering of more than 2 of the layers of different specific spring strengths described according to the invention can of course also be used to increase the number of variants.
  • slip resistance is preferably provided, which prevents the layers from shifting horizontally relative to one another. Otherwise, over time, this can occur through movements on the mattress and cause undesirable changes in shape.
  • Slip resistance can in particular friction-increasing materials or releasable connections, z. B .: be Velcro straps.
  • the sink-in zones of the layers are preferably formed by several cavities - also called spring pockets - extending next to one another, in particular parallel to one another, over the width of the mattress. These make it easier to compress, there Foam material can be pressed into these cavities.
  • One possibility of making the spring strength on the top side less than the spring strength on the underside in the sinking area of the layer is, for example, cavities closer to the top than to the underside of the layers.
  • the reduced specific sinking zone spring strengths in the area of two superimposed sinking zones of the two superimposed layers are designed so that in the harder layer the smaller of the two reduced specific sinking zone spring strengths is greater than the larger of the two reduced specific sinking zone spring strengths in the softer position. Otherwise, the properties partially cancel each other out when swapping and / or turning.
  • cuts preferably extend from the surface of the upper side of the layers in the direction of the cavities, preferably over the entire width of the mattress.
  • the cuts ensure that the strips at least touch each other and cannot be moved completely independently of one another, which can lead to holes / steps in the surface.
  • the spring deflection behavior of the sinking zones can be influenced by the cross section of the cavities.
  • a constant spring strength over long spring travel is obtained with round and square cross-sections.
  • cross-sections are preferred which have a spring line that increases with the spring travel. These are in particular in the form of a downwardly corrugated or accordion-shaped cross section.
  • Mattress pads or "toppers” for short can form the top of a mattress. This is a mat a few centimeters thick, which is supposed to increase sleeping comfort in every lying position and is gentle on the mattress underneath.
  • the topper often consists of virgin sheep's wool, horsehair, cold foam, viscoelastic material or latex and usually a cover that can be removed for hygienic reasons. As a continuous topper, it creates a common lying area in the double bed.
  • Further mattress variations can be provided if a mattress topper can be provided on the upper of the two layers, the two sides of which have different comfort-relevant properties, with one side preferably consisting 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 by the user with or without the mattress topper and the mattress topper can optionally be detachably connected with one of its two sides to the upper of the two layers.
  • Each layer is preferably provided with its own cover, in particular with slip resistance to prevent the layers from slipping horizontally against one another. This protects the sensitive foam layers from dirt and mutual abrasion.
  • the cover can have a slip-resistant effect or be designed so that the layers do not slip against each other, e.g. E.g .: by means of a thin elastic fleece or net.
  • a common elastic fleece or net can also be used, which envelops all layers, optionally including an overlay, in order to make it more difficult for the layers to slip relative to one another.
  • a cover that can be opened without tools is provided to cover and hold the mattress core formed from the layers, the layers are protected and securely held and can be replaced and turned.
  • the mattress topper can also be encased and held by the envelope.
  • the cover is preferably closed by means of a zipper, in particular all around, so that the cover can exert pressure on the mattress core.
  • the height of the layers is preferably 6-15 cm, preferably 8-12 cm.
  • the mattress topper 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 layers H, W made of foam material on top of one another. These have different specific spring strengths, which are formed here by the different compressive strengths of the materials. Therefore, in Fig. 1 the upper layer the softer layer W and the lower layer a harder layer H.
  • Both layers H, W lying on top of one another each have two different sink-in zones ZH, ZW (left and middle position) to accommodate the hip area and shoulder area of a person lying on the mattress.
  • the right sink-in zones mirror the right shoulder zone, so that the foot and head end of the mattress are interchangeable.
  • Pockets or incisions ensure that the sinking zones ZH, ZW have a specific sinking zone spring strength that is reduced compared to the specific spring strength of the respective layer H, W.
  • the sink-in zones for the hip area and shoulder area can have different spring strengths and be designed differently, but are subject to the following conditions:
  • Fig. 1 also shows that the two layers each have an upper side OH, OW and an underside UH, UW.
  • the sinking zones ZH, ZW are worked into the two layers H, W in such a way that the spring strength changes by turning against a load from above:
  • the upper sides OH, OW in the area of the sinking zones have the reduced specific sinking zone spring strength and the Undersides UW, UH in the area of the sinking zones a mean specific sinking zone spring strength, the strength lies between the reduced specific sinking zone spring strength and the specific spring strength of the respective layer.
  • the pockets or incisions of the sink-in zones point downwards, so that the sink-in zones are less soft. If, on the other hand, the incisions point upwards, the strips formed by the incisions can deflect deeper independently and therefore more easily.
  • the lower layer H which, by turning it around, allows the sinking zone ZW located above it to be influenced further without influencing the overall hardness of the mattress. Rather, this is influenced by the top-bottom exchange of the two layers H, W.
  • the sink-in zones ZH of the lower layer H point downwards, so that overall there is less softness of the mattresses in the area of the sink-in zones.
  • An envelope 20 holds the two layers H, W together. On top of this lies the mattress pad 30, one side 31 of which consists of viscose foam and the other side of gel foam 32.
  • Fig. 2 shows the matrix of the possible combinations of the two layers H, W which can be reversed according to the invention and can be exchanged at the top and bottom.
  • the lower layer is here with the pockets / incisions facing down.
  • the strips formed by the incisions cannot deflect independently of one another and are therefore relatively difficult to compress.
  • the total hardness of the mattress is achieved by exchanging the top and bottom of the two layers. With the same configuration, this exchange results in a change in the degree of hardness from H1 to H3 or from H2 to H4.
