BACKGROUND OF THE INVENTION This invention relates to a bed mattress.

[0002]

2. Description of the Related Art A conventional bed mattress is constructed by connecting coil springs to each other with fixing devices and arranging the coil springs vertically and horizontally, surrounding the peripheral surface with a frame such as a wire, and covering the upper and lower sides with a cover material such as a cold gauze. In general, a layer is formed, and if necessary, an appropriate pad layer is laminated, and the front side and the back side are covered with a cloth as a mattress outer material, and the periphery is closed.

[0003] Such a mattress is in close contact with the body because the upper surface of the mattress is flat when in use, and a recess along the line of the body is partially formed by the elasticity of the spring layer. Contact on a wide area of the body may impair blood circulation in the body or cause pressure ulcers. In addition, when the contact area between the body and the upper surface of the bedding is increased, the flow of air therebetween is obstructed, and the temperature and humidity may be too high. Further, in the conventional mattress, the feeling of use is determined by the hygroscopicity, heat retention and the like of the cotton wool, and it is not possible to appropriately select a warm feeling or a cool feeling.

[0004] Further, since the conventional mattress has the above-described structure, it is necessary to separate the metal such as the spring from the pad, the side ground and the like at the time of disposal, and the processing requires extra labor and labor. I was

SUMMARY OF THE INVENTION The object of the present invention is to provide a bed mattress which can be selected to have a warm feeling or a cool feeling as required, and is lightweight and can be easily disposed of when disposed. I do.

[0006]

The present invention comprises a synthetic resin box having a plurality of through holes on the bottom and four sides, and a synthetic resin lid having a plurality of through holes on the top and four sides. Then, the lid was put on the box via elastic members covering the four circumferential side surfaces of the box, and both were fitted and integrated.

[0007]

Since the mattress of the present invention has the above-mentioned structure, even if the entire upper surface is bent in the shape of an inverted character due to the weight of the lying person, a concave portion corresponding to the body shape is partially formed. It is close to the body and does not impede the blood circulation of the lying person, and the mattress has good ventilation since it has holes, so it can reduce the temperature and humidity to obtain a cool feeling, and conversely
If you want to get the feeling, fit it in the space formed by the box and lid.
Fill the filling material. Further, when the mattress is discarded, it can be easily crushed and discarded as it is or incinerated without sorting according to the material.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

The mattress of the present invention is a synthetic resin box 2 having a plurality of through holes 1 on the bottom and four sides, and a synthetic resin lid having a plurality of through holes 3 on the top and four sides. The cover 4 is integrally fitted over the box 2 via a elastic member 5 covering the four circumferential side surfaces of the box 2 in a U-shape.

As shown in FIG. 3, the box 2 and the lid 4 intersect a plurality of bending-resistant synthetic resin linear members 6 having a flat or elliptical cross section in a lattice pattern. And formed into a box shape or lid shape, for example, obtained from a linear body of various thermoplastic synthetic resins such as polyester resin and polyolefin resin, and integrally molded by pressure molding It can be easily formed as a product or by means such as perforating a synthetic resin plate with a punching press.

In the latter method, not only a thermoplastic synthetic resin but also a thermosetting synthetic resin can be used. Further, the size of the through-hole is preferably small, and the configuration between the through-holes can be made thick and strong at the central portion of the upper surface of the lid 4 which is heavy in weight.

The elastic member 5 covering the four side surfaces of the box 2 in a U-shape is preferably made of, for example, polyurethane foam, polyolefin synthetic resin foam rubber such as polyethylene or polypropylene, or other various elastic materials. When the lid 4 is fitted to the cover 2, the gap between the four peripheral side surfaces of the box 2 and the four peripheral side surfaces of the lid is filled, thereby serving as a cushioning material for firmly fitting and integrating the two. Considering the air permeability inside the mattress, the elastic member 5 uses an open-cell foam or
An appropriate ventilation hole may be provided, or a part where the elastic member 5 is not provided on a part of the four circumferential side surfaces of the box 2 may be formed.

In using the mattress of the present invention, the mattress is placed on a bed frame, further laid with a thin duvet or cushion, and laid on it. At that time, the mattress may bend due to the weight of the lying person, but does not form a partial recess along the body shape of the lying person. Because of the presence of 3, excellent air permeability can be maintained at a low temperature and humidity, and a cool feeling can be obtained.

In order to obtain a warm feeling when used in winter, the box 2
The space formed by the cover 4 and the cover 4 may be filled with a suitable filling material such as cotton wadding to prevent air permeability.

[0015]

As described in detail above, the bed mattress of the present invention is provided with a synthetic resin box having a plurality of through holes on the bottom and four sides, and a plurality of through holes on the top and four sides. The lid is made of a synthetic resin lid, and the lid is placed on the box via the elastic member covering the four side surfaces of the box, and the two are fitted and integrated. Despite flexing due to the weight of the body, it does not form a dent along the body shape like a conventional mattress using a coil spring, and as a result, it may impair blood circulation in the body and cause pressure ulcers Of course, the top and bottom surfaces of the mattress have a plurality of through-holes, so they are excellent in air permeability, can keep the temperature and humidity low and can have a cool feeling, and can be appropriately placed in the space formed by the box and the lid. Filling with filling material prevents air permeability It is also possible to get a warm feeling.

Further, when disposing the mattress of the present invention, it is possible to easily crush it and dispose it as it is or incinerate it. In particular, it is possible to incinerate such a polyolefin synthetic resin, for example, polyethylene or polypropylene resin. When it is made of a synthetic resin that does not generate toxic gas, the influence of environmental pollution due to incineration can be minimized.
