Description

The invention relates to a mattress having a mattress pad formed in a longitudinal direction and a transverse direction, which comprises a core pad, an upper pad and a lower pad and in which the core pad on its facing the upper pad and padding large areas with over the transverse direction extending rounded ribs and the Upper cushion and the lower cushion is provided with facing the core cushion recesses whose width corresponds to the width of the ribs and whose depth is greater to form an air duct than the height of the projecting into the respective recess rib.

The mattress pad of a mattress, in particular lying mattress, determines the lying characteristics of the mattress and in particular the lying hardness. The mattress pad is usually surrounded on all sides with a mattress cover, which is preferably removable to be washed or replaced. In some cases, the mattress is supplemented by a cover layer which is inserted between the mattress cover formed by the mattress cover and the relevant side of the mattress pad. If the mattress to be supplied on both sides, a cover layer may be provided on both large areas of the mattress pad.

The lying characteristics, which are determined by the mattress pad, include in particular the lying hardness. Mattresses are therefore divided into several (for example, four) hardness classes, in order to give the interested party an orientation as to whether he prefers to lie on a firm or very firm or a soft or very soft mattresses and sleeps. Moreover, it is known to provide different hardness ranges over the longitudinal direction of the mattress, ie the direction in which the person lying on the mattress is intended to be aligned from head to foot, for example, to help lower the shoulder of the person lying on the mattress to allow a firm support of the head, whereby a kinking of the neck of the person lying on the side is avoided. Similarly, the waist may be supported and the pelvic area allowed to sink in to provide the most direct possible alignment of the spine of the person lying on the side.

Numerous solutions have become known for constructing mattresses in their height direction, ie perpendicular to the lying surface, in two parts. In particular, for a reversing mattress, which is to be supplied from both sides, it may be useful to provide for a lying surface towards a harder material and the other lying surface a softer material so that the person using the mattress on demand from a harder lying surface on a softer lying surface and vice versa by turning the mattress can change. The dividing line between the two parts of the mattress pad can be a plane that is aligned parallel to the lying surfaces, but can also consist of a wavy extending surface. In such a mattress is in DE 299 17 541 U1 provided that the two lying surfaces are interconnected by elastic positive locking means consisting of widthwise extending webs, which dip into undercut grooves, thereby filling the groove completely.

US 3,222,697 discloses a two-part mattress, in which both parts are formed by a respective smooth outer side and a mutually facing profiled inside. The profiled inside has square or corrugated webs. The two parts of the mattress are stacked so that the webs are perpendicular to each other. The parts of the mattress can be cut from a base body with the aid of a hot wire formed in the profile shape. In such a three-part construction, the center piece pointing up and down profiling on. The preparation of a base body is then carried out with two heated wires which are formed parallel to each other. The composition of the mattress takes place after rotation of the center piece by 90 °, so that the profiles of the center piece on the one hand and of the upper part and lower part on the other hand perpendicular to each other.

By CH 477 847 is a three-part mattress known in which the middle layer may consist of a harder foam than the two outer layers. The two interfaces between the three layers are flat. In this parting plane, an intermediate layer is introduced, which is glued to at least one of the two adjacent layers. The intermediate layer consists of a tensile stress not or only slightly yielding network, z. B. jute. This liner is intended to provide greater stability to the mattress so that softer and less durable materials can be used for the foam layers of the mattresses.

DE 295 03 620 U1 discloses a mattress consisting of a unitary mattress body, which is provided on at least one side with mutually parallel webs, through which the comfort of lying is to be improved. The cutting out of several mattress body from an initial block of material takes place without loss of formation of the webs.

A mattress with a mattress pad of the type mentioned is as a mattress AR S 18th in the brochure "Annette Rummel" (as of February 2009) of Rummel-Matratzen GmbH & Co. KG, Neustadt / Aisch , known. The mattress pad has over the height of a three-part structure in which the upper cushion and lower pads are identical and the mattress pad is constructed mirror-symmetrically in a section in the longitudinal direction, so that no head and foot are defined. Upper cushions and lower cushions are each supported on a core cushion, which is formed by a 4 cm thick plate. On the surface facing the core cushion surfaces of the upper cushion and the lower pad these have approximately U-shaped recesses. The core pad is zoned with ribs that can engage in the recesses. Ribs are only in a central region of the core cushion, wherein the height of the rib decreases starting from the center and is reduced to about zero in the region of the rib cage, so that in this area no more ribs are present. Only at the extreme ends of the core pad has two ribs, which engage in recesses. Of the 34 recesses each of the upper cushion and the lower cushion, 18 remain empty, ie no ribs protrude into it. The core cushion is also reinforced in the middle area by a special insert. The core cushion thus essentially has the function of providing different lying zones over the longitudinal direction of the mattress. The formation of the recumbent zones is supplemented in the transverse direction by incisions of the upper cushion and the lower cushion which are open to the side of the couch, numerous incisions being present in the softest possible area (eg shoulder area), while a halved number of incisions is provided for the pelvic area. Between these areas are areas without cuts. The cuts are intended to contribute to the formation of support and relief zones through the core cushion. However, a system used for this, which corresponds to the supporting effect of the core cushion, is not recognizable. Furthermore, it is not apparent how the parts of the mattress pad are held together. Usually for this bonds are. As a relative movement in the longitudinal direction is excluded by the engaging in the recesses ribs for the known mattress, it seems conceivable to hold the mattress pad only by the mattress cover. However, this considerably complicates the handling.

The present invention is based on the problem of being able to produce mattresses in a rational manner with different degrees of hardness, mattresses with a uniform lying surface, but also with a distributed over the longitudinal direction in different hardness zones lying surface to be produced.

To solve this problem, a mattress of the type mentioned in the invention is characterized in that the core pad in the longitudinal direction one behind the other equally spaced ribs of the same height and has a greater hardness than the upper cushion and the lower cushion, so different bedding different mattresses of the mattress are adjustable and that the upper cushion and the lower cushion between the recesses ribs of the same height form, which engage in existing between the ribs of the core cushion recesses, wherein the ribs are each formed with a slight excess over the associated recess and so deeply engage in the recesses that upper cushion , Core padding and padding without fasteners to form a stable for the handling of the mattress cohesion.

The mattress according to the invention thus has a three-part construction, which corresponds to the structure of the known mattress. By the measures according to the invention, however, it is ensured that a firm cohesion between upper cushion, core cushion and lower cushion is given and that the hardness of the mattress is determined decisively by the core pad used. As a result, upper cushions and lower cushions can be used unchanged for all hardness classes, while the respective hardness class is set exclusively by the core cushions.

It should be noted that the use of the terms "upper cushion" and "lower cushion" is not intended to be committed to a top of the mattress and a bottom of the mattress, since the invention is of course also applicable to a reversing mattress on both sides of a Has lying surface. After turning the mattress would then be the "lower cushion" above and the "upper cushion" below.

The mattress according to the invention may be formed with a uniform lying surface but is preferably a formation of upper cushion and lower cushion with several hardness zones over the longitudinal direction of the mattress, wherein the hardness zones are not formed mirror-symmetrical in the vertical section, so for the bed surface, a head and a foot are defined. In this way, it is possible to achieve an anatomically more adapted support of the body lying on the mattress, in particular in its lateral position.

The mattress according to the invention can thus be assembled in the manner of a modular system. It can be kept upholstery and padding, for example, have a uniform bed surface on the one hand and a multi-zone bed surface on the other hand. These upholstery and Underpadding can be combined with different core padding to realize mattresses of different lay hardnesses.

The core pad is formed in a preferred embodiment of a uniform material with which the desired degree of hardness is adjustable. Accordingly, mattresses in three degrees of hardness can be offered with, for example, three different core pads and only one type of upper cushion and lower cushion.

If, in addition or alternatively, upper and lower cushions with several hardness zones are kept available over the longitudinal direction, multi-zone mattresses can be created in three degrees of hardness without having to change the upper cushions and lower cushions for this purpose.

The formation of the multiple lying zones through the upper cushion and the lower cushion can be realized in a conventional manner by different incisions on the side of the upper cushion or cushions.

Alternatively or additionally, it is of course possible to effect the multi-zone formation of upper cushion and lower cushion by the upper cushion and the lower cushion from different sections, such as different densities of a foam, are assembled to form the desired multiple zones.

It is also possible to realize the multi-zone training also composed of several materials core pad. In this case, preferably, a uniform upper cushion and lower cushion can be used.

In a further embodiment, it is possible to use a core pad composed of different materials and to form the upper pad and lower pad in a corresponding manner with corresponding multiple zones, so that the zones of upper pad and lower pad on the one hand and core pads on the other coincide in the longitudinal direction. The formation of the different zones of upper cushion and lower cushion can be done by a corresponding variation of the incisions or by a composition of upper cushion and lower cushion of different pieces of material, which preferably differ only by their density.

In all cases, only different core cushions are required for mattresses of different hardness, while upper cushions and lower cushions are used in an unchanged manner for different degrees of hardness.

The ribs of the core pad, which are directed to the upper cushion on the one hand and the lower pad on the other hand, may be in pairs at the same height with respect to the longitudinal direction. However, a configuration in which the ribs directed toward the upper cushion are offset from each other by half the distance between the ribs with respect to the ribs facing the lower bolster allows a more rational manufacture of the core bolsters from a large core cushion block. Since a rib facing the upper upholstery is arranged with a recess facing the lower padding in the longitudinal direction at the same height, this results in a shape of the core padding which allows a substantially constant material thickness.

For the cohesion of upper cushion, core cushion and lower cushion according to the invention, it is advantageous if the ribs are limited in longitudinal section over part of their length by at least approximately parallel wall sections, which merge only at the top of the rib in a rounded end shape. The substantially parallel sections of rib and associated recess ensure due to their static friction for a firm cohesion between the upper cushion and core padding on the one hand and core pad and padding on the other. As a result, the mattress can be handled uniformly without any adhesive bond or other connecting means, without the risk that the parts of the mattress unintentionally separate from one another. The uniform handling is maintained even when the mattress pad is removed from the mattress cover.

The invention will be explained in more detail below with reference to exemplary embodiments illustrated in the drawing. Show it:

1 a longitudinal section through a mattress according to the invention;

2 a plan view of the mattress according to 1 ;

3 an enlarged detail of a first embodiment of the invention;

4 an enlarged detail of a second embodiment of the invention;

5 an enlarged detail of a third embodiment of the invention;

6 an enlarged detail of a fourth embodiment of the invention.

1 shows a longitudinal section through a mattress according to the invention a mattress pad 1 that has a top cushion 2 , a core pad 3 and a lower cushion 4 is formed. This shows the core cushion 3 to the upper cushion 2 and padding 4 pointing ribs 5 on that in corresponding recesses 6 of the upper cushion 2 and the underpad 4 protrude so that upholstery 2 , Core padding 3 , Padding 4 interlocked with each other.

2 clarifies that the mattress pad 1 - And thus the mattress - has a longitudinal direction L and a transverse direction B and that the ribs extend straight in the transverse direction B in this embodiment.

3 illustrates a first embodiment of a mattress pad according to the invention 1 , The core pad 3 consists of a uniform material whose hardness is greater than that of the uniform material of the upper cushion 2 and the underpad 4 , Ribs 5 of the core cushion 3 are through recesses 7 of the core cushion 3 separated from each other, preferably a same width and an inverse (inverse) shape as the ribs 5 exhibit. About the length of the mattress pad 1 Preferably, the core pad has between 10 and 14 equally spaced ribs 5 on.

The recesses 6 from Oberpolster 2 and padding 4 are inverse to the shape of the ribs 5 educated. Preferably, the recesses 6 through the ribs 5 completed. Here is the width of the ribs 5 (ie their extent in the longitudinal direction L) slightly larger than the width of the recess 6 so the ribs 5 under a longitudinal direction L directed bias in the recesses 6 to sit. The excess of ribs 5 opposite the recesses 6 is preferably between 0.1 and 1.5 mm. Of course, it does not have the full height of the ribs 5 but is sufficient even if the excess only over a portion of the rib 5 opposite the recess 6 is available.

Between the recesses 6 has the upper cushion 2 and the underpad 4 a rib 8th on that in the recess 7 of the core cushion 3 protrudes, but has a small height than the recess 7 , so that between the bottom of the recess 7 and the rib 8th an air duct 9 located, for a transverse ventilation of the mattress body 1 provides.

3 lets recognize that the air ducts 9 only between ribs 8th of the upper cushion 2 and / or the lower pad 4 and the associated recess 7 of the core cushion 3 are formed, but not between rib 5 of the core cushion 3 and recess 6 from Oberpolster 2 or underpadding 4 because the ribs 5 the associated recess 6 completely complete.

On her the core pad 3 facing away from the top, which is thus directed to the mattress surface of the mattress, have upper cushion 2 and padding 4 in the transverse direction B running incisions 10 in the known manner ensure that upper cushion 2 and padding 4 are slightly softer on the surface than in the solid body, whose material hardness is designed for a certain support function.

In the mattress pad according to the invention 1 has the core cushion 3 a significantly higher material hardness than upper upholstery 2 and padding 4 , The lying hardness of the mattress altogether is therefore due to the hardness of the core cushion 3 certainly.

This in 4 illustrated second embodiment of the invention differs from the first embodiment according to 3 just by being in the top of the upholstery 2 and padding 4 different cuts 10 . 10 ' . 10 '' are introduced, with which different areas over the longitudinal direction L of the mattress pad 1 will be realized. The cuts 10 ' that has a larger cavity with a larger width and greater depth than the U-shaped cuts 10 contain cause a deeper sinking of the body into the mattress at the same weight. In contrast, the cuts convey 10 '' that have a small incision depth than the incisions 10 have a greater support hardness.

The width of the incisions 10 . 10 ' . 10 '' at the top of the mattress should be the same size so as not to give an irritating feeling to the person lying on the lying surface. The larger width of the incisions 10 ' is therefore realized only in a larger incision depth.

The core pad 3 is opposite the core cushion 3 according to the first embodiment as well as the recesses 6 and ribs 8th from Oberpolster 2 and padding 4 ,

This in 5 illustrated third embodiment corresponds in principle to the second embodiment of 4 , where the different zones of the upper cushion 2 and the underpad 4 now through different material sections 2.1 . 2.2 and 2.3 of the upper cushion 2 and 4.1 . 4.2 and 4.3 of the underpad 4 are formed. The material sections 2.1 . 2.2 and 2.3 are suitably glued together. The same applies to the material sections 4.1 . 4.2 and 4.3 ,

In this embodiment, the cuts 10 be designed so that they do not cause different zones. Of course but can in different material sections 2.1 . 2.2 and 2.3 also different cuts 10 . 10 ' . 10 '' be provided to support the zone training.

At the in 6 illustrated fourth embodiment are upper pads 2 and padding 4 as shown in the first embodiment uniform. This is a core cushion 3 ' used, which consists of several material sections 3.1 . 3.2 ., 3.3 composed like this in 6 is indicated schematically. The material sections 3.1 . 3.2 and 3.3 can be conveniently glued together. They serve to form different Lieharden over the longitudinal direction L of the mattress pad 1 ,

It should be noted that the illustration in 6 is only schematic. Regularly the material sections become 3.1 . 3.2 and 3.3 extend over much more ribs than in 6 is shown. The training of the length of the different lying zones depends - as the expert knows - on how many different lying areas are realized. A common number is five or seven different hardness zones. The resulting lengths of hardness zones are readily apparent to those skilled in the art.

Even if the core pad 3 ' from several pieces of material 3.1 . 3.2 and 3.3 composed, remains the overall shape of the core pad 3 ' the same as the core pad formed of a uniform material 3 ,

Although in the illustrated embodiments, the upper cushion 2 and to the underpad 4 pointing ribs 5 of the core pad always at the same height with respect to the longitudinal direction L, it is not excluded by the present invention and even with advantage realized that the ribs 5 leading to the upper cushion 2 show relative to the ribs 5 leading to the upholstery 4 show half a distance between the ribs 5 offset, so that the upper cushion 2 pointing rib 5 at the same height as one to the lower cushion 4 directed recess 7 , In this way, a shape of the core pad, which corresponds to a wavy line with a substantially constant material thickness results.
