Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to improvements in pine tresses used mainly in hospitals and the like.

(Prior art) In general, a pinerest is made by connecting a large number of springs in a flat plate shape with helical wires, providing a frame line on the periphery of the upper and lower surfaces to form a spring unit, and covering the upper and lower surfaces of the spring unit with protective material such as sisal. It is constructed by sequentially polymerizing an elastic body such as urethane foam, and covering this polymer with a bag-shaped exterior body.

The exterior body is made of plain-woven fabric, mainly for the purpose of improving breathability and feeling during use. Therefore, the breathability is good, and the pine tress absorbs and releases sweat and moisture brought by the user during use, so moisture does not accumulate between the user and the pine tress, providing comfort. I can go to bed.

(Problem to be solved by the invention) However, when the pine tress with the above structure is used in a hospital, the pine tress is covered with a sheet, but the user may spill medicine or spill food on the pine tress. By doing so, the pine tress itself becomes easily soiled. If dirt adheres to the exterior body of the pine tress in this way, it becomes very difficult to remove this dirt. If the exterior body is made of fabric, the pine tress cannot be easily washed and can only be washed to remove dirt. Even if you wipe it off, it is difficult to remove the dirt stuck between the fibers of the fabric, making it impossible to keep the pine tress sanitary at all times. In addition, although pine tresses used in hospitals are regularly sterilized with chemicals, it is difficult to sterilize the inside of the pine tresses, and bacteria may invade inside the pine tresses, making them unsanitary. There is a problem.

The present invention was developed based on the above-mentioned circumstances, and its purpose is to easily remove dirt even if it adheres to the exterior body of the pine tress, and to prevent bacteria and pests from entering the pine tress. The purpose is to provide a pine tress that can be used cleanly at all times.

(Means and functions for solving the problems) In order to solve the above problems, the present invention forms the exterior body that covers the core of the mattress with a bag-shaped airtight sheet, eliminating the breathability of the mattress. Therefore, it is easy to wipe off dirt that has adhered to the exterior body of the mattress, and it is also easy to wash it. Also, because it is not breathable, bacteria cannot get into the inside of the mattress.
It can always be used hygienically.

(Example) Examples of the present invention will be described below based on the drawings. In the figure, 1 is a nakazukuri body. This nakazukuri body 1
The spring unit 5 is formed by connecting a large number of coil springs 2 . . . in a flat plate shape with helical wires 3 . A protective material 6 such as a coil pad is laid on the upper and lower surfaces of this spring unit 5, an elastic body 7 such as cotton felt is laid on the upper surface of this protective material 6, and a gold cloth 8 is laid on the upper surface of this elastic body 7. , the ends of the protective material 6 and the elastic body 7 are wrapped around the ends of the gold cloth 8, and the spring unit 5 is
Clip 9 to spring 2 located on the periphery of
It is configured by being fixed by...

Then, the inner structure 1 is covered with an exterior body 10 to constitute a pine mattress. The exterior body 10
In this method, airtight sheets 11, 11 such as vinyl chloride resin sheets are laid on the upper and lower surfaces of the inner structure 1, and the sheets 11 are placed at the four peripheral edges of the center in the thickness direction of the inner structure 1. , 11 are welded to each other to form a bag shape, thereby covering the inner structure 1.

According to the pinerest with the above configuration, the outer casing 10 covering the inner structure 1 is formed into a bag shape by welding the four peripheral edges of the airtight sheets 11, 11. body 10
Even if dirt adheres to the surface, it can be easily wiped off or washed. In other words, when fabric was used for the exterior body like in conventional pine tresses, dirt particles stuck between the fibers and could not be easily removed, or the pine tresses could not be washed. Since the invention uses an airtight sheet, dirt particles do not get into the sheet and dirt can be easily wiped off. Moreover, even when washed with water, water does not enter the inside of the pine tress, and the pine tress can be kept clean. In addition, the inner structure 1 is covered with airtight sheets 11, 11, and the peripheral edges of the sheets 11, 11 are welded to each other, so that the inside of the pine tress is completely sealed, and no external air is allowed to enter the pine tress. There is no chance of entering. Therefore, even if this pine tress is used in a hospital or the like, various bacteria will not invade the inside of the pine tress. Bacteria adhering to the exterior body 10 may be easily sterilized using a disinfectant or the like. Even if the outside of the pine tress can be sterilized like with conventional pine tresses, the bacteria that have invaded the inside of the pine tress cannot be sterilized, and the bacteria that have invaded inside the pine tress may come out outside during use. You can always keep your pine tress clean and sanitary.

(Effects of the Invention) As described above, in the present invention, the exterior body covering the inner structure of the pine tress is formed of an airtight sheet. Therefore, the dirt adhering to the mat can be easily removed by wiping it off or washing it. Moreover, since bacteria and the like do not invade the inside of the pine tress, there is an advantage that the pine tress can always be kept clean.
