Description

  The present invention relates to a multilayer spring mattress having at least one core layer including a coil spring and a fabric.

Mattresses are used by being installed on various support structures and floors.
Conventional mattresses are mainly divided into two groups.
One is a group of spring mattresses that include coil springs in which the core layers are made of steel wires and connected to each other and arranged in contrast over the entire length of the mattress. The cushioning material used is a material (sponge, natural rubber, synthetic latex, low-temperature foam material, coir fiber, cotton, wool) generally used for mattress products.

Such a spring mattress is disclosed in Patent Document 1, Patent Document 2, Patent Document 3, and Patent Document 4, for example.
The disadvantage of these conventional spring mattresses is that the spring arrangement is not considered for different loads applied by different parts of the human body. The spring is fixed by mechanical means and is stabilized by a distance holder or a support frame. There is not enough consideration for air circulation and ventilation inside the mattress.

In conventional mattresses, another major group is so-called natural or organic mattresses.
Natural mattresses are usually made of coir fiber or latex rubber. By combining these materials, many different mattress types are created.
Although coir fiber and latex are partially elastic, they are less capable of following the contours of the human body than spring mattresses.

  The problem to be solved by the present invention is to provide a multi-layer spring mattress that provides anatomically appropriate support to the human body, more specifically, a special arrangement of the mattress layer and the coil spring, so that the joints and spine can be sound. An object of the present invention is to provide a multilayer spring mattress that can support and accurately conform to the unevenness of the human body.

The multilayer spring mattress of the present invention is comfortable to use through a special arrangement of coil springs and air circulation inserts installed in the core layer, as well as a holding layer and a flexible layer superimposed on the core layer. It enhances sex.
In order to achieve the above object, the multilayer spring mattress of the present invention comprises at least one core layer including a coil spring and a fabric, and the core layer is perpendicular to the main axis of the coil spring and has a holding layer attached thereto. The coil spring is disposed in a transverse region that occupies a central third in the length direction of the core layer and is held in its position by the holding layer. The part is arranged in a lateral region occupying the other 2/3 of the core layer.

The following configuration may be adopted.
A configuration in which an elastic holding insertion member is installed inside a coil spring.
A configuration in which the core layer has two surfaces perpendicular to the main axis of the coil spring.
A configuration in which a holding layer is attached to two surfaces of the core layer perpendicular to the coil spring.
A configuration in which the coil spring is held by being embedded in at least one holding layer.
A configuration in which at least one flexible layer is attached to the retaining layer.
A structure in which the layers are connected to each other by a detachable coupling means.
The configuration in which the coil spring is wooden.

According to the multi-layer spring mattress of the present invention, the coil spring that stores compression energy is installed in the lateral region that occupies the center 1/3 where the weight of the human body is the most, so that the spine can be reliably and flexibly supported. The joint can be protected and the coil spring can be held in a stable position by the holding layer.
Moreover, since the insertion part for air circulation is arrange | positioned in the horizontal area which occupies other 2/3 of a core layer, internal air circulation and ventilation can be ensured.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
As shown in FIGS. 1, 2 and 3, in three preferred embodiments of the present invention, the multi-layer spring mattress has a single core layer 1 including a coil spring 2.
The material of the core layer 1 is a homogeneous material (FIGS. 2 and 3) or a porous material (FIG. 1). The core layer 1 has at least one surface perpendicular to the main axis of the coil spring 2 (for example, a surface located at the bottom of the core layer 1 in use).
In the embodiment shown in the figure, the core layer 1 has two such surfaces: a surface located at the bottom of the core layer 1 in use and an upper surface.

The holding layer 4 is attached to at least one of these surfaces. In the embodiment shown in the figure, the holding layer 4 is attached to the two surfaces of the core layer 1, and the coil spring 2 is held in that position by the holding layer 4. The coil spring 2 is held by a means such as embedding in at least one of the holding layers 4 or bonding or sewing to the surface of the holding layer 4.
The coil spring 2 may be held by installing the holding insert member 5 having elasticity inside the coil spring 2 and attaching the holding insert member 5 to the holding layer 4.
The adoptable holding structure of the coil spring 2 is shown in FIGS.

The coil spring 2 is three times longer than steel and is completely in its original shape when the load is removed, so as to remove the unpleasant and negative biological effects that electromagnetic fields can have on the human body. It can be a wooden coil spring that returns.
In contrast, the coil spring 2 divides the mattress core into an anatomically comfortable region in a hole formed in the material of the core layer 1 in the central 1/3 horizontal region in the length direction of the core layer 1. Alternatively, they are installed according to an asymmetrical arrangement.
The load bearing force and weight distribution are adjusted by changing the installation density of the springs.
FIG. 4 shows an installation example of a spring. As is clear from FIG. 4, the air circulation insertion portion 3 is disposed in a lateral region occupying 2/3 of the end portion of the core layer 1 in order to reduce the applied load.

The multilayer spring mattress of the present invention includes one or more flexible layers 6. The flexible layer 6 can be disposed on one surface or both surfaces of the core layer 1, and the multiple flexible layers 6 can be laminated together.
The material of the flexible layer 6 may be a homogeneous material or a porous material. Moreover, the surface shape of the flexible layer 6 can be smooth, corrugated, or bowl-shaped.

In the embodiment shown in FIG. 2, the core layer 1 is made of a homogeneous material, and the upper flexible layer 6 is made of two divided layers 6a and 6b. The upper surface of the upper divided layer 6a has a bowl shape, and the bottom surface is smooth. The upper divided layer 6a is made of a homogeneous material, and the lower divided layer 6b is made of a porous material.
The lower flexible layer 6 has a smooth and corrugated shape on the top and bottom surfaces, respectively, and is made of a homogeneous material having antibacterial properties.
In the embodiment shown in FIG. 3, the core layer 1 is made of a homogeneous material, and the upper and lower flexible layers 6 are formed of a plurality of divided portions having upper and lower surfaces that are corrugated or bowl-shaped and different in hardness.

The material of the core layer 1, the holding layer 4, and the flexible layer 6 can be a low-temperature foam material, latex, viscoelastic foam material, polyurethane foam material, coir fiber, or the like. Furthermore, the holding layer 4 can be made of a wood material.
Further, the core layer 1, the holding layer 4, and the flexible layer 6 may be connected to each other by a detachable connecting means.

As shown in FIGS. 1, 2, and 3, the multi-layer spring mattress includes a futon 7. The futon 7 is preferably made of a natural material such as soybean fiber, bamboo fiber, wool or cotton.
In addition to improving the appearance, the futon 7 protects the mattress from dirt. The futon 7 is made of an antiallergenic and high-purity material that has a ventilation effect and does not prevent the release of heat and moisture from the mattress, and prevents the growth of house dust mites and bacteria.

The main advantage of the multi-layer spring mattress of the present invention is that the anatomically formed structure provides secure but flexible support for joint protection and spine. Pressure is transmitted from the mattress surface through the flexible layer 6 to the core layer 1, and compression energy is stored by the coil spring 2. Thus, the mattress properly supports different parts of the spine at all body positions.
This mattress can also provide optimal and uniform weight distribution, good shape stability, great elasticity and effective internal air circulation and ventilation, extending the life of the product. Furthermore, different areas with different hardness exactly follow the irregularities of the human body.
