Description

The invention relates to a foamed mattress body.

Foam mattresses are well known in the art. It is also known in latex mattresses to provide zones of different hardness. Thus, it is known, in particular, that in the middle region of a mattress the zone located there is harder than the zones arranged longitudinally in the longitudinal direction thereof. The reason for this can be found in the fact that usually in the pelvic area of humans there the highest Support is required, and there as a result, the highest stiffness or hardness of a mattress is required.

However, it is also true that people are of different sizes. That is, a mattress that is suitable for a person who has a height of 1.80 m, is not suitable for persons with a height of 2.0 m or even only 1.50 m. This is because the central support zone for this particular group of people is no longer exactly in the area of the pool, but above or below. In other words, mattresses are always a compromise.

In addition, not only the arrangement of zones of different stiffness or hardness is a problem, but it is also necessary to ensure that the moisture generated during sleep can be discharged through the mattress body to the environment. In this context, it should be noted that during the sleep phase, the body has a fluid loss of about 1 - 1 ½ l. This moisture must, as already explained, be dissipated. Insofar is already out of the DE 10 2006 025 136 B4 known to provide a mattress body having a recess, wherein in the recess spring elements can be adjusted from a foam having a core bore centrally. The spring elements themselves can have different stiffnesses. In this respect, it is possible to provide zones of different rigidity or hardness over the surface of the mattress. This means that spring elements are used in the pelvic region, ie in the middle region of the mattress, which are stiffer than those intended for the shoulder region, since the mattress should be more flexible in the shoulder region. The mattress known from this reference is certainly able to absorb a certain amount of moisture, just because of the free volume of air in the mattress body, the release of moisture to the Environment is however quite limited. The reason for this is to be found in the fact that on both sides of the spring elements, ie above and below the spring elements, a continuous foam layer is provided, which sets natural limits to such a moisture exchange.

In this context, other references are known, in particular from the DE 20 2005 015 047 U1 a package of individual spring elements made of a foamed material known, which are held together by a pull rope as a package. Also in this package zones of different hardness are provided, which result from the fact that the core holes in the spring elements have a different diameter. In this respect, a certain ventilation is also possible here, and in particular also because the spring elements have a continuous core hole.

The DE 43 00 418 A1 in turn describes a mattress, wherein two layers are provided, wherein on the one layer a number of support bodies are arranged spaced from each other, wherein on the support bodies, a foam layer is provided.

From the DE 103 27 258 A1 In this context, a mattress body is known, which has a plurality of spring bodies, wherein the spring bodies are formed by crosswise arranged channels in the foam body. That is, it is known a variety of mattresses, which both have zones of different hardness, as well as are able to deliver moisture to a greater or lesser extent to the environment.

However, it is often difficult and expensive to produce such mattresses. In this context, reference is made in particular to the already mentioned DE 10 2006 025 136 B4 in which a mattress body is provided, which has a recess into which individual spring elements are adjustable. To produce a finished mattress, a foam layer is then placed on the mattress body with the spring elements in the recess. That is, such a mattress consists of a plurality of parts, which makes the production of such mattresses considerably more expensive.

In addition, from the utility model DE 94 00 132 U1 a mattress floor is known which has a plurality of arranged on the top and bottom blind holes. The cross section of the blind holes in this case is smaller in the pelvic area of a person lying on it than in the shoulder or in the head area. That is, the mattress has zones of different hardness. In addition, the blind holes are different deep recessed in the mattress floor.

The object underlying the invention is therefore to provide a mattress body and a mattress, on the one hand has different hardness zones over the surface of the mattress, which allows a good ventilation of the mattress, and which is also inexpensive to produce.

A foamed mattress body with zones of different hardness, which satisfies these premises, according to the invention is characterized in that the mattress body comprises a horizontally extending layer of foamed material, wherein the layer on one side on both sides of the central transverse axis a plurality of mutually spaced, interconnected by webs, provided with a core hole dome, the height of the dome is different, the thickness of the layer decreases with increasing dome height and increases again with lower Domhöhe. From this it becomes clear: where the Cathedral height is the largest, the mattress is the most yielding, since there the proportion of foamed material is the lowest. Conversely, where the dome height is the lowest, the stiffness of the mattress body is highest. In this respect, by varying the height of the dome zones of different hardness or zones of different stiffness are provided, with otherwise the same height of the mattress body.

The invention is also the spaced arrangement of the dome to each other. The domes are in cross section as circular elements, which, as already stated, spaced from one another in the mattress body are arranged. By the spaced arrangement of the dome to each other a relatively large volume of air is provided within the mattress body between the domes, which is correspondingly able to absorb a significant amount of moisture.

Advantageous features and development of the invention can be found in the dependent claims.

It is thus provided in detail that the dome height of a number of rows of cathedrals, as seen from the central transverse axis, initially increases in the longitudinal direction of the mattress and then decreases again. From this it becomes clear that the highest dome height is to be found approximately in the area of the shoulder, whereby in the shoulder area the place is given, where the mattress should be relatively pliable, in order to ensure that the shoulder can sink into this area, in such a way To achieve as straight as possible alignment of the spine of the sleeper. Here, in the transverse direction of the mattress, the adjacent dome are the same height.

On the other side of the layer of the mattress body a plurality of juxtaposed dome heads are provided as a continuation of the dome on the other side of the layer, wherein at zones of greater hardness several dome heads are connected by the intermediate spaces between the dome heads filling material surface. The connection of the dome heads through the space between these dome heads filling material will be provided in the region of the central transverse axis, since, as has already been mentioned variously, at this point the body requires an increased support force.

Incidentally, the individual dome heads are connected to one another by webs extending parallel to the central transverse axis of the mattress body. In the same way, according to a further feature of the invention, the domes are connected to one another by webs running parallel to the central transverse axis of the mattress body. In both cases, the webs serve to increase the stability of the dome as such. This means that the dome, although they are spaced apart from each other, still supported by the connection of the webs against each other and thus in the lateral direction, d. H. have increased rigidity in the plane of the mattress body.

It has already been mentioned elsewhere that a mattress in addition to zones of different hardness or stiffness, generally also be able to deliver absorbed moisture to the environment. This purpose is served not only by the space between the domes, but also by the core holes arranged in the domes. On the one hand, such a core bore or opening creates a further volume for absorbing and releasing moisture, but on the other hand, such a core bore can also influence the degree of rigidity of the mattress at different zones. That is, there is a possibility without a fundamentally different one

To make mattress structure to one or both sides z. B. the mid-range for short people to make this area by shortening the core holes slightly harder. That is, by varying the core bore length can be provided with relatively little effort for zones of different hardness. Manufacturing technology, different lengths of metal pins are used for the core holes in the mattress mold as a tool. Thus, mattresses can be made for different sized people with minimal effort, but in their basic structure, however, are the same.

It has already been pointed out that the dome have a distance from one another in the longitudinal direction of the mattress and are connected to one another in the transverse direction by webs. The distance between the domes extends over the entire row of adjacent domes, forming a channel between the rows of cathedrals.

Furthermore, it is provided that the mattress body has a peripheral edge, which is formed of the same material as the mattress body also, ie of a foam.

It has also been pointed out that in the region of the central transverse axis of the mattress body should be stiff. In this context, it is provided that on both sides of the central transverse axis in a central region of the space between the domes is filled by a foamed material, which corresponds to that of the remaining foam body. The longitudinal extent of the central region comprises about 40-50 cm, so extends over the height of the pelvis of a person. In order to ensure a ventilation in this area, several rows of juxtaposed vertically aligned core holes are arranged in the central region of the mattress body. These core holes penetrate the mattress body over its entire height, which ensures ventilation of the mattress body even in the area of increased rigidity.

The invention also relates to a mattress, characterized by two mattress bodies lying on top of each other, as have been described above, wherein the dome of each mattress body lie with their end faces on top of each other. That means, the dome heads point outwards. The arrangement of two mattress body in the manner described above, the production of a relatively comfortable Mattress considerable height possible, it being noted that this only a form is required because the two mattress body, which are placed on top of each other, are the same. Nevertheless, it should also be mentioned at this point that the mattress body as such can already function as a mattress.

In order to improve the ventilation even in a mattress consisting of two mattress bodies, a plurality of horizontal core holes are arranged according to a further feature of the invention at the edge of the mattress, each of which opens into the channel between the domes. It has already been pointed out that in the middle region the mattress body is substantially more or less solid over a length of 40-50 cm, with the proviso that there are vertical core bores extending through the mattress body. Also there are such horizontal core holes provided, however, extend in this central region over the entire width of the mattress, d. H. from one end to the other opposite end, in particular between the vertical core holes located there. As a result, the ventilation of the existing essentially of a foam material middle part of the mattress body or the mattress is ensured.

As it turned out FIG. 1 results, the mattress designated 1 consists of the two mattress bodies 10 which are glued to each other lying on each other. The formation of the mattress body to form the mattress results in detail from the intuition of FIGS. 2 and 3 ,

The designated 10 mattress body has a circumferential edge 9 and a bottom and a top. On the underside, ie on the side on which it is glued to the other mattress body to form the mattress 10, a plurality of rows 11 consisting of individual domes 12 are provided within the edge 9, which are arranged on a layer 10a, in particular foamed. The individual dome rows 11 extend on both sides of the central transverse axis 8 in the longitudinal direction of the central region 14. Channels 15 are located between the individual rows of catheters 11. The cathodes 12 of the individual rows of cathodes 11 are formed to form the channels Webs 16 connected. That is, the individual domes 12 are supported on the webs in the transverse direction of the mattress body (arrow 26). In the middle region 14, the channels 15 between the rows of cathodes 11 are filled with foam material, so that this zone is relatively stiffer in the middle region 14 than the zones present on both sides of the middle region. However, zones of different hardness are also provided on both sides of the central region, which is accomplished by the cathedral rows having different heights. In this context, on the FIG. 3 directed. Thus, in the region 17, the dome 12 is of lesser height than in the adjacent region 18 and in the further adjacent region 19, wherein the region 20 shows rows of dome with a height which corresponds approximately to the height of the region 18.

The core holes 13 in the domes are continuous, that is, they extend from the domes on the underside of the Mattress body 10 through the dome heads 22 on top of the mattress body, wherein the dome heads as well as the dome are within the edge 9. The core holes can also be designed as blind holes. Both by the dome height and by the choice of the length of the core holes there is the possibility of adjusting the stiffness of the mattress relative to individual zones.

Also in the area of the dome heads on top of the mattress zones of different hardness are provided, which is accomplished by the rows 23 of individual dome heads 22, wherein within the rows 23, the individual dome heads are interconnected by webs 24, channels 25 between the Domkopfreihen 23rd are formed, which are filled at different points of the mattress body by foam material. Such areas 27, 28, 30 and 31 can be found at various locations on the upper side of the mattress body, in particular in the middle area 14 and on both sides thereof, as can be seen in FIG FIG. 1 results.

It has already been pointed out elsewhere that the dome 12 and the dome heads 22 may have continuous core holes 13, that is to say that the dome heads communicate with the domes through the core bores 13. Such core holes are also provided in the central region 14; they are labeled there with 33. These core holes are formed continuously, that is, they extend from the top of the mattress body to the bottom of the mattress body.

A mattress 1, consisting of two superimposed mattress bodies 10 results in section in the view of FIG. 3 , There it can be seen that the mattress body shows on its longitudinal side horizontally aligned core holes 35 which extend into the channels 15 between the cathedral rows 11. Also in the central region 14 are such horizontally aligned core holes 35 provided, however, the local core holes 35 extend in the horizontal direction through the mattress over the entire width. The horizontal core holes 35 in the middle area are located between the vertical core holes 33 in this area.

The individual mattress body to form a mattress are made of a foam, with different hardnesses are already possible in the selection of the foam.
