Description

Technical field

The utility model object relates to a multi-layer spring mattress having at least one central layer comprising coil springs, the mattress also comprising a coating. The mattress can be used by placing it on any supporting structure or on the floor.

BACKGROUND OF THE INVENTION

Known solutions belonging to the field can be divided into two main groups. The first is a group of spring mattresses, the central mattress layer comprising interconnected coil springs made of steel wire, arranged symmetrically along the entire length of the mattress. The padding materials used are those commonly used for the production of mattresses (porous, natural and synthetic latex, cold foam, coconut fiber, cotton, wool). Such solutions are described, for example, in GB 1,006,735, US 6,272,706, WO 2004/039215, and GB 2,198,938. The disadvantage of these solutions is that the arrangement of the springs does not take into account the different loads represented by the different zones of the human body. The springs are secured by mechanical means and are stabilized by the use of separating elements or supporting frames. Internal air circulation and mattress ventilation are problematic.

Another important group of known solutions is represented by so-called natural or organic mattresses. Natural mattresses are usually made of either coconut fiber or natural rubber. By combining these materials, many different types of mattresses are produced. Although both coconut fiber and natural rubber are locally resilient, they lag behind spring mattresses in their ability to follow the body contour.

The utility model aims to provide, by circumventing the disadvantages of existing solutions, a spring mattress that provides anatomically adequate support to the body, in particular by applying a special arrangement of mattress and spiral spring layers to provide such a mattress that can offer healthy support for joints and spine, accurately follow the outline of the body.

The essence of the technical solution

The multilayer spring mattress according to the present utility model is based on the recognition that a multilayer spring mattress can provide improved comfort through a special arrangement of helical springs and air circulation inserts located in the central layer and other stabilizing and comfort layers deposited on the central layer.

The objective is met by providing a multilayer spring mattress wherein at least one layer is a central layer comprising coil springs, the mattress also having a coating. According to the present solution, the central layer has at least one surface oriented perpendicularly to the axis of the coil springs, with a stabilizing layer attached to said surface, wherein the coil springs are disposed in a transverse belt occupying the middle third of the central layer and wherein the coil springs are secured to the stabilizing layer, for air circulation, located in the transverse strips, occupying an additional two-thirds of the central layer.

According to a preferred embodiment of the multi-layer spring mattress according to the utility model, the stabilizing pads are located within the helical springs, the stabilizing pads being made of a resilient material.

According to a preferred embodiment, the utility model mattress has a central layer with two surfaces oriented perpendicular to the major axis of the coil springs.

According to a further preferred embodiment of the utility pattern, the respective stabilizing layer is attached to each of the two surfaces of the central layer oriented perpendicular to the axis of the coil springs.

According to yet another preferred embodiment of the utility pattern, the coil springs are secured to at least one of the stabilizing layers by incorporating them into them.

In yet another preferred embodiment of the utility pattern, the at least one comfort layer is attached to the stabilizing layer.

In yet another preferred embodiment of the utility pattern, the mattress layers are secured to one another by releasable connections.

According to a preferred embodiment of the utility model, the coil springs are designed as wooden coil springs.

Examples of technical solution

As shown in FIG. 1, 2, 3, all three preferred embodiments of the multilayer spring mattress comprise a central layer 1. The material of the central layer 1 may be homogeneous (Fig. 2, 3) or perforated (Fig. 1). The central layer 1 has at least one such surface (for example a surface located at the bottom of the central layer 1 in the use position) which is oriented perpendicular to the major axis of the spiral springs 2. According to a preferred embodiment shown in the drawings, the central layer 1 has two such surfaces: The surface located at the bottom of the middle layer in the use position has an upper surface having the necessary orientation. The stabilizing layer 4 is attached to at least one of these surfaces. In the embodiments described with respect to the drawings, the stabilizing layer 4 is attached to each of the two surfaces, with coil springs 2 secured to the stabilizing layers 4. The coil springs 2 may be stabilized either by embedding them in at least one of the stabilizing layers 4 or by securing them to the the surface of the stabilizing layer 4, for example by means of an adhesive bond or other releasable or non-releasable bond such as by sewing or stitching. The coil springs 2 can also be secured to the stabilizing layers 4 by arranging the flexible stabilizing inserts 5 in the spiral springs 2 and securing the inserts to the stabilizing layers 4. Possible ways of securing the spiral springs 2 are best seen in Figs. 5-7.

The coil springs 2 are preferably realized as wooden coil springs that fully assume their unloaded shape after loading, withstand three times longer than their steel counterparts, eliminate the noise effects and also the negative biological effects that they may have on the human body by directing electromagnetic fields. The coil springs 2 are located in the openings formed in the material of the central layer 1 in a transverse belt occupying the middle third of the central layer 1, in a symmetrical or asymmetrical arrangement, which preferably divides the mattress core into ergonomic zones conforming to the anatomy of the human body. The dynamics of the reinforcement and the weight distribution can be adjusted by changing the density with which the springs are distributed. Fig. 4 shows a possible arrangement of springs. As can be seen in the drawing, in the transverse strips occupying the two outer thirds of the central layer 1, the air circulation inserts 3 are positioned for lightweight dynamics.

The multilayer spring mattress according to the present utility model also includes one or more comfort layers 6. The comfort layers 6 may be located on one or both sides of the central layer 1, and the multilayer comfort layers 6 may be disposed on top of each other. The material of the comfort layers 6 may be homogeneous or perforated. The comfort layers 6 may have, for example, a smooth, wavy or ribbed surface configuration.

As can be seen in FIG. 2, in one possible embodiment the central layer 1 has a homogeneous material, while the upper comfort layer 6 consists of two parts 6a, 6b. The top surface of one portion 6a of the comfort layer 6 is ribbed while its bottom surface is smooth. The material of part 6a is homogeneous, while the material of second part 6b is perforated. The top and bottom surfaces of the lower comfort layer 6 have, respectively, a smooth and wavy configuration, said comfort layer 6 having a homogeneous antibacterial material.

Similarly to the embodiments described above, in the embodiment shown in FIG. 3, the central layer 1 has a homogeneous material, while the upper and lower comfort layers 6 consist of multilayer parts of different rigidity, with both surfaces of the comfort layers 6 corrugated or ribbed.

The material of the middle layer 1, the stabilizing layer 4 and the comfort layer (s) 6 may preferably be a cold foam, latex, viscoelastic foam, polyurethane-based foam or coconut fiber. In another preferred embodiment, the stabilizing layer 4 may be made of a wood-based material.

As can be seen in FIG. 1, 2, 3, the multilayer spring mattress comprises a coating 7. The coating 7 is preferably made of natural materials such as soy fiber, bamboo fiber, wool or cotton. In addition, to improve the appearance of the arrangement, the mattress cover 7 protects it from dirt. The coating may be made of an antiallergic, very pure material allowing efficient ventilation and providing optimal heat and moisture transfer from the mattress, and preventing the proliferation of domestic mites and bacteria.

6-Τ

The main advantage of a multi-layer spring mattress is that its anatomically designed structure provides excellent protection for the joints and a firm yet flexible support for the spine. The pressure is transmitted from the mattress surface towards the central layer 1 via the comfort layers 6, where the compression energy is dynamically stored by the helical springs 2. Thus, the mattress provides adequate support for the different parts of the spine in all body positions.

The mattress ensures an optimal even distribution of the weight, plus good shape stability, excellent flexibility, efficient internal air circulation and ventilation, and extended product life. Different zones adjusted for different stiffness can follow the body contours very precisely.
