Definitions

• the invention relates to a mattress core according to the preamble of claim 1.
• the invention is based on the object of improving a generic mattress core in such a way that it enables a particularly versatile adaptation of a multi-layer mattress equipped therewith in a very economical manner. Furthermore, the invention is based on the object of providing a correspondingly versatile mattress.
• the mattress core has only two layers and these two layers have different firmnesses
• a basic choice between a softer and a harder mattress setting can be made by turning the mattress, whereby turning the mattress then also allows further adjustment, similar to fine-tuning the desired sleeping climate.
• One embodiment may accordingly provide for the recesses to be designed as incisions that open into the surface of the layer.
• the recesses may be designed as channels that extend through the layer in the longitudinal and/or transverse directions, and whose respective cross-sections are bounded all around by the material of the layer.
• the long sides are longer than the front sides.
• the dimensions of the mattress core are practically unlimited, especially its longitudinal and transverse dimensions. In one design, however, the long sides are longer than the ends.
• This elongated design of the mattress core allows for the provision of a correspondingly elongated mattress, so that when used in a double bed, a common mattress is not intended for two people, but rather both people can use their own mattress and accordingly the sleeping comfort provided by the mattress can be individually adapted to the individual wishes or needs.
• the dividing line is curved in a substantially S-shape.
• the dividing line between the upper and lower layers can, for example, run in a straight line, rising or falling, or it can have several straight sections of varying gradients. In one embodiment, however, the dividing line essentially curves in an S-shape, resulting in a smooth, continuous transition between the different layer thicknesses of the upper layer of the mattress core. This results in an equally smooth, continuous transition between zones of different firmness, enabling the highest possible sleeping comfort for a person lying on a mattress equipped with this type of mattress core.
• the upper and/or lower layer consists of a foam material.
• the upper and/or lower of the two layers of the mattress core is made of a foam material.
• Foam materials have proven themselves to be excellent for mattress production for years. They can be provided in various sizes with high precision and their external shape can be easily and precisely processed, ensuring the desired dividing line between the upper and lower layers. layer can be ensured.
• the additional processing steps mentioned above to create recesses in the material of a specific layer of a mattress core have been tried and tested in practice, thus providing additional options for influencing the lying sensation and resulting sleeping comfort of a mattress equipped with a correspondingly designed mattress core.
• the mattress core has more than two layers arranged one above the other.
• This layer designed as a barrel pocket spring core, can, however, also be an additional layer of the mattress core.
• the mattress core can have more than the two layers designed according to the invention, the dividing line of which does not run parallel to the top or bottom of the mattress core.
• an additional third layer can be provided, which can, for example, have a constant layer thickness and is located between the two mentioned layers, so that the mattress core has two dividing lines that do not run parallel to the top or bottom of the mattress core.
• an additional layer - either as the mentioned third layer or as an additional, fourth layer - can form the underside of the mattress core as the lowest layer, whereby the upper side of this lowest layer can either run parallel to the underside of the mattress core in one embodiment or, in another embodiment, can also not run parallel to the top or underside of the mattress core.
• a second aspect of the invention relates to a mattress with a mattress core having a number of the features described above and below, and with a mattress cover enveloping the mattress core.
• a number refers to a singular or a plural number of a respective feature.
• a mattress designed according to the invention has the mattress core designed according to the invention and a mattress cover that envelops the mattress core.
• the mattress cover where it lies against the long sides of the mattress core, to be provided with a line which runs along or parallel to the dividing line between the upper and lower layers of the mattress core.
• the course of the dividing line which does not run parallel to the top or bottom of the mattress core between the two layers, can be visualized on the outside of the mattress cover, since the mattress core itself is no longer visible due to the mattress cover.
• the mattress cover is therefore where it meets the long sides of the mattress core. It is provided with a line that runs along the dividing line between the two layers of the mattress core. This makes it immediately apparent during use whether the thickness of the upper layer in the shoulder area is comparatively thick or thin, depending on the rotation of the mattress.
• the mattress cover is composed of at least two parts, namely an upper and a lower part, these two parts can be designed differently, for example, have different structures with quilted seams or the like, have different patterns and/or colors, so that, due to this different design, the mattress cover also has a dividing line that runs between its upper and lower parts. In one embodiment, this dividing line of the mattress cover runs parallel or preferably congruent with the dividing line of the mattress core.
• the mattress cover has a zipper which runs along at least one long side of the mattress core and there along or parallel to the dividing line between the upper and lower layers of the mattress core.
• the mattress cover is removable from the mattress core, for which purpose the mattress cover can be opened using a zipper.
• the zipper can run along at least one long side of the mattress along the dividing line between the two inventive layers of the mattress core, so that the zipper forms the aforementioned line that visualizes the course of the dividing line between the two layers.
• Fig. 1 shows a longitudinal section through a cuboid foam block 1, which can be separated along an S-shaped dividing line 2 into two identical sections 3 and 4.
• Fig. 2 shows a longitudinal section through a cuboid foam block 5, which can be separated into two identical sections 6 and 7 along a dividing line 2 that is also curved in an S-shape.
• the dividing lines 2 of both foam blocks 1 and 5 are identical and are therefore marked with the same number 2.
• the upper section 3 of the foam block 1 can therefore be placed directly onto the lower section 7 of the foam block 5 to create a mattress core consisting only of these two layers.
• the structure of a more complex mattress core is explained below purely as an example:
• Fig. 3 shows a third, comparatively flat foam block 8, which extends over the same length as the two foam blocks 1 and 5.
• a barrel pocket spring core 9 is shown, which is both shorter and narrower than the foam blocks 1, 5 and 8.
• the Barrel pocket spring core 9 is therefore assigned edge elements 10 made of a foam material, which can be arranged longitudinally next to the barrel pocket spring core 9 as edge elements 10l and on the front side in front of and behind the barrel pocket spring core 9 as edge elements 10s, so that the barrel pocket spring core 9 and the edge elements 10l and 10s surrounding it together cover the same base area as each of the foam blocks 1, 5 and 8.
• Fig. 4 shows a mattress core 11 in which the upper section 3 of the foam block 1 forms the uppermost layer of the mattress core 11 and the lower section 7 of the foam block 5 forms the lowermost layer of the mattress core 11.
• Below the uppermost layer is the flat foam block 8, and between this and the lowermost layer are the barrel pocket spring core 9 and the edge elements 10l and 10s surrounding it as the second lowest layer of the mattress core 11.
• the two dividing lines 2 of the mattress core 11 therefore separate, on the one hand, the two upper layers from one another, i.e., the upper section 3 from the flat foam block 8, and, on the other hand, the two lower layers from one another, i.e., the lower section 7 from the barrel pocket spring core 9 and the edge elements 10l and 10s.
• both the foam block 8 and the barrel pocket spring core 9 and the edge elements 10l and 10s are basically cuboid-shaped and thus have upper and lower sides running parallel to each other, a further S-shaped curved dividing line 2 results between these two middle of the four layers of the mattress core 11.
