Description

The invention relates to a mattress for sitting and / or lying furniture, in particular in the embodiment as a bed mattress, with a preferably formed from a foam body and a plurality of spring strands, which are each formed of a plurality of interconnected spring elements and their respective longitudinal extent their each transverse extent substantially exceeds, wherein the body provides chambers that serve to receive the spring strands.

Mattresses in general, as well as bed mattresses in particular, are well known in the prior art, so there is no need for a documentary proof at this point.

Generic mattresses have a main body on the one hand and spring strands on the other. In this case, the base body is preferably formed from a foam. Other materials come into question, such as latex.

In order to provide a suspension comfort satisfying the highest requirements, it is known from the prior art to equip the mattress base body with spring elements, ie to design spring elements within the base body. As a well-known design in this context, the pocket spring mattress called.

Pocket spring mattresses have proven themselves in everyday practice. In this case, coil springs made of spring steel are typically used. The generic mattress, however, relates to one that has spring elements made of plastic. The use of plastic spring elements is in many ways advantageous over metal springs. On the one hand offer plastic spring elements improved suspension comfort while simplifying and thus cheaper production. On the other hand, plastic spring elements prove to be low-wear and less susceptible to corrosive media.

The generic mattress has spring elements interconnected spring elements. Such spring strands are known from the prior art, for example from the AT 509316 B1 , of the EP 2 116 152 A2 , of the AT 10826 U1 and the EP 1 808 100 A1 , All these spring strands have in common that their respective longitudinal extent significantly exceeds their respective transverse extent, ie, the spring strands have an extension in the longitudinal direction, which significantly exceeds their extent in the transverse direction.

For arranging such spring strands within a main body of a mattress, the base body has corresponding chambers. In the intended use case, these chambers each take a spring strand possibly also several such spring strands, such as with the EP 2 116 152 A2 disclosed.

The invention has the object of providing a mattress of the type mentioned, that is to further develop the generic type with respect to the provided by her sitting and / or lying comfort.

To solve this problem, a mattress of the type mentioned is proposed with the invention, which is characterized in that the chambers are aligned for receiving the spring strands in their longitudinal extent in the longitudinal direction of the mattress.

So far, it is the opinion in the art that spring strands of generic mattresses are to be aligned transversely to the mattress longitudinal direction in order to achieve an adequate suspension comfort. This idea is based on the fact that it allows a transverse division of the mattress in a particularly simple manner, in the longitudinal direction of the mattress successive zones with different suspension comfort provide. Corresponding disclose the previously cited documents, each showing aligned transversely to the longitudinal extent of the mattress spring strands.

The invention takes a completely different approach and proposes, in contrast to the prior art and overcoming the prejudice prevailing in the art, to align the spring struts receiving chambers of the body in their longitudinal extent in the longitudinal direction of the mattress, i. to choose such a configuration, which are aligned in accordance with the spring strands no longer in the transverse but in the longitudinal direction of the mattress. Accordingly, the invention proposes an alignment of the spring strands parallel to the spine of a mattress according to the invention in the intended use of the user.

Investigations have shown that the design according to the invention surprisingly offers enormous advantages. Thus, the longitudinal alignment of the spring strands allows a body to be accommodated in a sleep-like manner in response to its weight distribution in the longitudinal direction and to be resiliently trapped. Without the need for different spring elements in their suspension properties, the longitudinal alignment of the spring strands allows comparatively heavy body areas, such as the buttocks area, to sink further into the main body of the mattress than less severe body areas, such as the head or shoulder foot area. The result is a natural and thus the highest demands fairing body alignment and suspension. In this case, the achieved suspension comfort always to the same extent, regardless of whether the user side, a body lateral position, a prone position or a supine position is taken. Furthermore, alignment of the mattress with respect to its head or foot region is no longer necessary. The provided according to the embodiment of the invention mattress allows a simplified application insofar as it is not necessary on the user side to distinguish between foot area on the one hand and head area on the other.

It was not expected in the forefront of the invention that with an alignment of the spring strands or the chambers receiving them in their longitudinal extent in the longitudinal direction of the mattress would be achieved in this way over the prior art improved suspension comfort. In this case, for the implementation of the embodiment of the invention from the prior art per se known base body on the one hand and from the prior art per se known spring strands used on the other. Of essential importance to the invention is only the orientation of the spring strands, in contrast to the prior art in such a way that the longitudinal extent of the spring strands now no longer runs in the transverse direction of the mattress, but in the longitudinal direction of the mattress.

The achieved with the inventive design positive effect is further improved when the mattress according to the invention is combined in combination with a resilient or equipped with spring elements pad known per se. To mention here is as a mattress pad, for example, the slatted frame. This typically has individual elastic slats, which are aligned transversely to the mattress in their longitudinal extent. In a combination of such known from the prior art slatted frame with a mattress according to the invention results in a matrix-like superimposition of the elastic slats of the slatted frame on the one hand and provided by the main body of the mattress spring strands on the other. In traditionally transversely oriented spring slats of a slatted frame, it comes in combination with mattresses known from the prior art, the spring strands are also aligned transversely, to a superimposition of each caused by the spring strands on the one hand and the spring slats of the slatted frame on the other hand, suspension forces or spring forces which may disadvantageously lead to a non-calculable gain or cancellation with a view to the overall achieved spring action. The embodiment of the invention provides a remedy, since it comes thanks to the mattress design according to the invention to a lattice-like superposition of the spring slats of the slatted frame on the one hand and the spring strands of the mattress on the other hand with the positive effect that adjusts a synergetic overall spring effect. On the one hand a calculable in the suspension comfort support of the mattress is achieved by the slatted base. On the other hand, it allows the mattress in alignment of their spring strands parallel to the spine of the mattress user to provide optimized sleeping comfort. The result is a total of the highest standards sufficient spring action.

With the invention, therefore, a mattress system with a mattress of the type according to the invention and a mattress support is proposed, wherein the mattress receiving mattress side is equipped with spring elements, preferably connected to a spring strand spring elements, wherein the spring elements and / or each of each interconnected Spring elements formed spring strands in the respective longitudinal extent is aligned transversely to the mattress / are.

The main body of the mattress according to the invention consists, according to a further feature of the invention, of two interconnected sections. These sections can be glued together, for example. The individual sections are arranged in the mattress height direction sandwiched one above the other. In this case, the two sections forming the main body are preferably formed identically to one another, so that it is not necessary to distinguish between the individual sections in the course of mattress production. The embodiment in sections has been found to be particularly advantageous because it ensures a simple assembly of the individual provided by the body chambers with spring strands.

Each section has a groove according to a further feature of the invention. This is one-sided, i. formed open with her the other portion of the body associated side, so far in cross-section forms a U-shaped configuration. The groove is aligned in its longitudinal extent in the longitudinal direction of the section or the mattress. When fully assembled state, the grooves of the two sections of the body in mattress height direction are superimposed, with their open sides facing each other. As a result, so formed for receiving the spring strands chambers form.

The spring strands are inserted according to a further feature of the invention without connecting means in the chambers. Accordingly, no additional connection means for the arrangement of the spring strands within the chambers of the body are used.

To produce a mattress according to the invention, the main body is first formed. This may be formed of a foam or latex. There is then a subdivision of the body in two sections, which can be done for example by cutting. The portions of the base formed in this way can then be formed with corresponding grooves. This can also be done by cutting but also by milling. In the grooves of one of the two sections then the spring strands are inserted. The prepared section can be glued in a subsequent process step with the second portion of the body. The base body thus equipped with spring strands can then be placed in a stocking or sack, preferably made of nylon. In a final process step, a casing with an outer material is then carried out.

As an alternative to the above-described procedure, the two sections of the basic body can also be formed separately from a foam material or from latex. According to this alternative, forming methods are used, according to which the grooves are formed with the formation of the sections from the outset, a subsequent cutting or milling is therefore not required.
