Description

The invention relates to a waterbed mattress comprising a Wasserbetthülle fillable with a liquid with a support surface, with a bottom surface and at least one side surface connecting the support surface and the bottom surface, wherein within the Wasserbetthülle as damping insert at least one stabilizing body is arranged, which is connected by retaining means with the Wasserbetthülle is for positioning the at least one stabilizing body in the Wasserbetthülle.

For example, from the EP 2 092 856 A1 is a waterbed mattress with a Wasserbetthülle known which is filled with a liquid, in particular with water. In the Wasserbetthülle stabilizing body are arranged as damping inserts to calm the waterbed. The stabilizing bodies are essentially flat formed and extend parallel to a support surface of the Wasserbetthülle. The stabilizing bodies break the swell of the liquid stored in the water-bed cover and at the same time increase the strength of the water-bed mattress.

As a stabilizing body today polyester fleece deposits or foams are placed in the Wasserbetthülle. Industrially manufactured polyester fleece liners are by far the most popular means of influencing mattress properties in terms of reverberation time and strength. The disadvantage here, however, on the one hand, the low strength of the nonwoven insert, which can lead to the deposit dissolves or tears. In addition, the use of nonwoven inserts promotes the formation of microorganisms in water, since the nonwoven material is very dense and forms an ideal seed. When using foam inserts - especially against polyester fleece deposits - the pressure-relieving effect of the waterbed is noticeably reduced, especially at high attenuation, so that the sleeping comfort is reduced. In addition, the aging properties of foam inserts in waterbeds are still largely unexplored. However, it is to be feared that particularly strongly calmed mattresses - similar to conventional mattresses - can be sagged with the consequence that, in particular, heavily used zones are less sustainable over time. Furthermore, the foam material used for the stabilizing body is very dense, so that the nucleation is favored as in the polyester fleece deposits.

Object of the present invention is therefore to provide a stabilizing body with improved permanently elastic properties, high strength and low nucleation tendency.

To solve this problem, the invention is characterized in connection with the preamble of claim 1, characterized in that the at least one stabilizing body of a flat upper fabric, spaced from one another to the same arranged planar Untertextil and from the upper fabric and the lower fabric spaced from each other supporting support threads is formed wherein the support threads are arranged between the upper textile and the lower textile.

The particular advantage of the invention is that a less dense stabilization body is created by the provision of two spaced by support threads spaced from each other textiles, which has a low nucleation tendency due to its structure. Due to the interconnected textile layers, the stabilizing body also has a high strength. This favors on the one hand the life of the stabilizing body. On the other hand, a tearing of the holding means is effectively counteracted by the stabilizing body. The elastic properties of the stabilizing body can in this case depending on the diameter of the supporting threads, their connection to the upper and lower fabric, the distance of the supporting threads to each other and a Crossing angle of the supporting threads can be adjusted according to the specifications of the manufacturer or customer.

According to a preferred embodiment of the invention, the supporting threads and / or the upper textile and / or the lower textile made of a plastic material, in particular of a plastic material based on polyester. By using a plastic material, the life of the stabilizing body is further increased and reduces the tendency to nucleation.

According to a development of the invention, the support threads are formed from a single thread strand. This advantageously increases the strength, in particular the tear strength of the support threads. A detachment of the upper textile from the Untertextil is counteracted thereby.

According to a development of the invention, at least two stabilizing bodies are arranged in the water-bed cover. The at least two stabilizing bodies are connected to one another here by holding means. Advantageously, the degree of damping of the waterbed mattress can be adjusted by providing a plurality of stabilizing bodies in an effective manner. The calming of the waterbed increases with the number of damping mats used. The individual stabilizing bodies can be made of the same or of different materials. The stabilizing body are usually mat-shaped and in terms of their dimensions matched to the waterbed mattress so that they are stacked in this.

According to a development of the invention, eyelets for fastening the holding means are arranged on the water-bed cover and / or on the stabilizing body. The holding means may be formed, for example, as cords. Advantageously can be simplified by the provision of eyelets of the assembly process for the introduction of the stabilizing body. The provision of eyelets and their attachment in particular to the stabilizing bodies is favored by the higher material and tear strength of the stabilizing bodies according to the invention.

According to a development of the invention, at least one buoyant means is arranged between the upper textile and the lower fabric of a stabilizing body and / or below at least one stabilizing body and / or between two stabilizing bodies for the floating arrangement of the at least one stabilizing body in the Wasserbetthülle. The holding means are dimensioned in this case, that is matched to the height of the Wasserbetthülle and the height of the stabilizing body, that the upper fabric of the support surface of the filled Wasserbetthülle facing upper stabilizing body is arranged spaced from the support surface. On the one hand, the desired calming is realized by the floating arrangement of the stabilizing bodies in the water-bed hull filled with the fluid. On the other hand remains However, the pressure-relieving effect typical of the water bed when lying on the support surface is obtained.

According to a development of the invention, the buoyancy means comprises at least one fluid chamber filled and / or filled with a fluid. For example, a foam with appropriate air inclusions, a stabilizing body formed from cell foam or a fillable air chamber can be provided as buoyancy means. Individually inflatable air chambers offer the advantage that the buoyancy can be adjusted individually. In contrast, buoyancy agents such as foam or the like offer cost advantages, since they can be further processed particularly economically. The assembly is comparatively easy.

According to a development of the invention, the fluid chambers can be arranged uniformly distributed on the stabilizing body for generating a uniformly acting on the stabilizing body buoyancy. Likewise, the fluid chambers may be distributed and / or arranged in zones such that individual regions of the stabilization body experience a higher buoyancy than others. Advantageously, certain body zones, such as the human pelvis, are supported more than others. Hardness and strength of the waterbed mattress can be adjusted individually.

Further advantages of the invention will become apparent from the further subclaims.

Embodiments of the invention will be explained in more detail below with reference to the drawings.

FIG. 1

a first embodiment of a waterbed mattress,

FIG. 2

an enlarged view of a region X in FIG. 1 and

FIG. 3

a second embodiment of the waterbed mattress.

A waterbed mattress 1 according to FIG. 1 has as essential components a Wasserbetthülle 2 and two stabilizing body 3.1, 3.2, which are arranged in the Wasserbetthülle 2. The Wasserbetthülle 2 has a support surface 4, a bottom surface 5 and the support surface 4 and the bottom surface 5 connecting side surfaces 6. The Wasserbetthülle 2 forms a container for storing liquid, such as water.

The introduced in the Wasserbetthülle 2 stabilizing body 3.1, 3.2 serve as damping inserts and for reassurance. The stabilizing body 3.1, 3.2 are mat-shaped and substantially parallel and spaced from the support surface 4 and the bottom surface 5 arranged in the filled with the liquid Wasserbetthülle 2.

Below the two stabilizing body 3.1, 3.2 is arranged as a buoyant means 7 each have a layer of cell foam. The cell foam body 7 has a constant thickness and extends over the entire surface along the stabilizing body 3.1, 3.2.

Of the cellular foam bodies 7 acts on the stabilizing body 3.1, 3.2 a uniform buoyancy, which can float in the liquid-filled Wasserbetthülle 2. A complete floating of the stabilizing body 3.1, 3.2 to the support surface 4 of the Wasserbetthülle 2 is prevented by holding means 8, via which the lower stabilizing body 3.1 is attached to the lower surface 5 of the Wasserbetthülle 2 and the upper stabilizing body 3.2 to the lower stabilizing body 3.1. Here are eyelets 9 for connecting the holding means 8 with the stabilizing bodies 3.1 and 3.2 and the bottom surface 5 of the Wasserbetthülle second

The length of the holding means 8, which may be formed for example as cords, is matched to the thickness of the stabilizing body 3.1, 3.2 and the thickness of the waterbed mattress 1, that the upper stabilizing body 3.2 spaced from the support surface 4 of the filled with the fluid Wasserbetthülle 2 is. By providing the holding means 8, accordingly, on the one hand, the relative position of the stabilizing body 3.1, 3.2 to each other fixed and slipping in the Wasserbetthülle 2 can be prevented. On the other hand, it is achieved that the stabilizing bodies 3.1, 3.2 are positioned at a defined distance from the support surface 4 of the waterbed cover 2. Depending on the number of stabilizing bodies 3.1, 3.2, which is introduced into the Wasserbetthülle 2, the damping and the strength of the waterbed mattress 1 varies.

The stabilizing body 3.1, 3.2 is according to FIG. 2 from a top fabric 10 and a bottom fabric 11 and from the top fabric 10 and the bottom fabric 11 connecting support threads 12 formed. The support threads 12 are arranged between the upper fabric 10 and the lower fabric 11 such that the upper fabric 10 and the lower fabric 11 are held spaced from each other. The upper fabric 10 and the lower fabric 11 extend substantially parallel to the support surface 4 and the lower surface 5 of the Wasserbetthülle 2. The support threads are crossed at an intersection angle α crossed to each other.

The support threads 12 may be formed as monofilaments, that is, as individual thread strands. They can be made of a plastic material, in particular of a plastic material based on polyester. Depending on the diameter of the supporting threads 12, the connection of the supporting threads 12 to the upper fabric 10 and the lower fabric 11, the distance and the length of the supporting threads 12 and the crossing angle α thereof, the hardness of the stabilizing body 3.1, 3.2 can be varied and adjusted.

The distance between the support threads 12 to each other is large compared to their diameter. As a result, the stabilizing body 3.1, 3.2 receives a low density. Due to the low density, the nucleation tendency of the stabilizing body 3.1, 3.2 is significantly lower than comparable stabilizing bodies, which are designed as polyester fleece inserts or foam inserts.

According to a second embodiment of the invention according to FIG. 3 For example, the geometry of the stabilizing bodies 3.1, 3.2 can vary. For example, the stabilizing body 3.1, 3.2 have a different thickness. According to an embodiment of the invention which is not shown, the length and width extent of the stabilizing bodies 3.1, 3.2 can also vary. In addition, the provision of buoyancy means on the lower stabilizing body 3.1 can be dispensed with. Instead, two buoyant means 7, 7 'of the upper stabilizing body 3.2 are dimensioned so that a sufficient buoyancy is given for all stabilizing bodies 3.1, 3.2 connected to one another via the holding means 8. The buoyancy means 7 is in contrast to the first embodiment of the invention along the mat-shaped stabilizing body 3.1, 3.2 unevenly, that is distributed in zones. This zoning offers the advantage that individual body zones, such as the human pelvis, are supported more than others.

The same components and component functions of the embodiments are identified by the same reference numerals.

According to an alternative embodiment of the invention, not shown, the buoyancy means 7, 7 'instead of a cellular foam body made of foam or be formed with a fluid, in particular air-fillable chambers. The buoyancy means 7, 7 'can be arranged below the stabilizing bodies 3.1, 3.2 between at least two stabilizing bodies 3.1, 3.2, or between the upper textile 10 and the lower fabric 11 of the stabilizing bodies 3.1, 3.2 and distributed uniformly or non-uniformly along the stabilizing bodies 3.1, 3.2 be.
