Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mattress.

[0002]

2. Description of the Related Art A mattress made of sponge and having a large number of irregularities on its surface is known from Japanese Utility Model Publication No. 47-26088. This is intended to have a massage effect due to the convex portion of the surface, and since the surface is uneven, it has good breathability and also has the effect of preventing acne such as bedridden elderly.

[0003]

This bedding does not pose a problem when it is laid on a tatami mat or a floor. But,
Since bed mats are generally thick and extremely flexible, when the above-mentioned soft mattress is laid on the mat, the mat follows the curve of the body. The mattress is also deformed, and the above effect cannot be achieved.

Therefore, the present invention provides a bedding that has the same effect as when it is laid on a soft object such as a bed mat, when it is laid on a hard object such as a tatami mat or a floor. To aim.

[0005]

Means and Actions for Solving the Problems The mattress according to the present invention comprises a surface layer made of a flexible material such as sponge and having an uneven surface, and a back layer made of a harder material. (Claim 1). Therefore, even if a person sleeps on this mat with a very highly flexible mat, etc., the surface layer is supported by the harder back layer. The whole is held substantially flat. Therefore,
The body is appropriately pressed by the unevenness on the surface of the mattress, so that the acupressure effect and massage effect peculiar to this mattress can be sufficiently exerted and the breathability is maintained.

The front and back layers may be integrally molded with a synthetic resin (Claim 2) or may be separately molded with a synthetic resin and heat-welded (Claim 3). By doing so, manufacturing is easy, and the unity as a bed is high.

The front and back layers may be formed separately, and they may be adhered or connected and fixed by stopping means (Claim 4). Further, they may be detachably connected via the stopping means. (Claim 5). In this case, it is preferable that both the front and back layers, which have various hardnesses and shapes, can be easily joined by various materials. Further, when the back surface layer is detachable from the front surface layer, it is preferable that the back surface layer can be removed when the bed is directly used on a floor or a tatami mat.

By the way, since the above-mentioned conventional mattress is flexible as a whole, it is folded in two or three to be transported or displayed in a store. However, since the mattress according to the present invention is relatively hard as described above, it is difficult to fold it. In order to eliminate such a secondary problem, the above-mentioned bed is divided into a plurality of parts in the longitudinal direction thereof, and they are detachably connected by a stop means or hinge means. It can be made foldable via (claim 6). Further, each of the parts thus formed can be housed in a bag, and the bags can be detachably connected by a stop means, or the bags can be foldably connected by a hinge means. (Claim 7). By doing so, when not in use, it is folded through the hinge means, or the stop means is released to separate and stack the parts. Further, when using this, the whole may be spread in a planar shape via the hinge means, or the respective portions may be connected in a planar shape by the stop means.

For the same purpose, the front and back layers may be separately formed, the back surface layer may be divided into a plurality of parts, and each part may be detachable from the surface layer. 8). In this case, when not in use, each part of the back surface layer is separated from the surface layer and the flexible surface layer is folded. Also,
When using it, attach each part of the back surface layer and make a relatively hard bed as a whole.

Further, the front and back layers are formed separately and are detachably attached to each other, and the back layer is divided into a plurality of portions, and each portion is detachably attachable via a stop means. Or can be foldably connected via hinge means (claim 9). Again, when not in use, the backside layer is removed from the topside layer and either separated into sections or folded via hinge means for storage in a compact form.

The materials for the front and back layers may be arbitrary. For example, one or both of the front and back layers may be formed of synthetic resin foam (claim 10). Further, the back surface layer is not limited to the plate shape, and may have a lattice shape or a net shape (claim 11), and the material thereof may be metal, synthetic resin, wood, bamboo or the like (claim 12).

1 shows a futon 10 according to an embodiment of the present invention. In the futon 10, the surface layer 12 is made of relatively soft urethane foam, and the back layer 14 is made of soft urethane foam that is harder than this.

On the surface of the surface layer 12, valleys and peaks are alternately arranged in the vertical direction and the horizontal direction, and the unevenness 16 is formed.
Is formed. The front and back layers 12 and 14 may be integrally foam-molded, or separately foam-molded and heat-welded or bonded together, or joined by a mechanical coupling means. Good.

The front and back layers 12, 14 may be made of any material. It may be synthetic resin (foamed or non-foamed), fiber, rubber or the like.

When both the front and back layers 12 and 14 are molded from synthetic resin foam, the hardness can be made different by adjusting the materials of both and the foaming ratio.

When the front and back layers 12, 14 are mechanically joined, they may be completely fixed by a stapler, a band or the like, or may be detachably attached. An example of the detachable attachment means is shown in FIG. Protrusions 18 having bulged tips are provided upright in appropriate places on the relatively hard back surface layer 14. The relatively soft surface layer 12 is provided with a recess 19 having a diameter slightly smaller than that corresponding to the above-mentioned protrusion. By pressing the back surface layer 14 against the front surface layer 12 and pushing the protrusions 18 into the recesses 19, both can be snap-fitted together. By grasping both layers 12 and 14 by hand and pulling them in the left and right directions, they can be separated.
Instead of such a shape connection, an arbitrary attachment / detachment means such as a hook, a hook, or a surface fastener may be used.

FIG. 3 shows another embodiment of the present invention. As described above, in order to eliminate the inconvenience of handling the back surface layer 14 made of a relatively hard material at the time of transportation or display at a store, the bed sheet 10 is divided into three parts 20, 22, 2.
It is divided into 4 parts. These parts 20, 22, 24
Are stored in bags 21, 23 and 25,
The cloth on the back side of the bags 21 and 23 is continuous, and the hinge 30 is formed at the continuous position. Similarly, bag 2
The cloth on the surface side of 3, 25 is continuous and forms a hinge 32. In this bedding 10, the portion 25 is folded above the portion 22 via the hinge 32 with the portion 22 as the center, and conversely, the portion 20 is hinged.
It can be folded underneath the portion 22 through the to form a three-fold fold. Since it can be compactly assembled in this way, it is easy to handle. 3 bags 2 like this
Bags 2
The three members may be connected to each other by a surface fastener or the like that is separate from 1, 23 and 25, and the surface fastener or the like may serve as a hinge. Also, these three parts are formed separately, and the parts 20, 2 are formed.
A string may be attached to each of the two adjacent ends, as well as a string attached to the similarly adjacent ends of the portions 22, 24. They may be separated during transportation and display, and when used, these strings may be tied together to make the three parties continuous.

Further, in order to achieve the same purpose as in the case of FIG. 3, the relatively soft surface layer 12 is integrally formed, and the relatively hard back surface layer 14 is divided into three parts to be formed. For example, each part may be detachably attached to the surface layer 12 via a snap means as shown in FIG. Alternatively, instead of this, the respective parts of the back surface layer 14 may be provided continuously via a hinge.

In the illustrated embodiment, synthetic resin foam is used as the back layer 14, but instead of this, non-foam synthetic resin or metal, wood, bamboo or the like may be used. Further, the back surface layer 14 does not have to be a solid plate body, and may be formed in a lattice shape or a net shape.

[0020]

When a person sleeps on the mat or the like having an extremely high flexibility, the entire bed is held by the back surface layer so that the entire bed is kept in a substantially flat shape. The body is appropriately pressed by the convex portion on the surface of the pork, so that the acupressure effect and the massage effect can be sufficiently exerted. Also, breathability is maintained.
