DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in the structure of a shirafu used for sleeping outdoors or the like.

[Prior art]

[0002] In general, the shirafu is the front part of the body (chest,
An opening / closing unit such as a chuck is provided on the upper part covering the abdomen and the front of the leg), and the face and head are exposed so that the back of the body (back, buttocks, back of the leg, etc.) , And each contains a material having elasticity, such as cotton, synthetic cotton, and blades, like a normal futon.

However, in the conventional shirafu, cotton,
Even though elastic materials such as synthetic cotton are used, due to portability, the amount of the material is smaller than that of ordinary futons and the like, thus avoiding the drawback that sufficient cushioning properties cannot be exhibited. I couldn't do that.

[0004] On the other hand, in the field of disaster prevention equipment and life-saving equipment for moving and resting the body on the body, a resilient and stretchable material such as sponge is contained therein, and the material is used during use. A structure that contributes to the convenience of carrying by expanding the material and exerting cushioning properties by inhaling air into the tool, compressing the material when not in use, discharging the inhaled air, and reducing the volume. Has been adopted.

[0005] However, there has been no idea to convert a disaster prevention tool or a lifesaving tool capable of realizing both cushioning and portability into an outdoor shirafu by sucking and discharging such air.

[0006]

SUMMARY OF THE INVENTION The present invention is to improve the structure of such prior art shirafu and to provide a shirafu structure which can exhibit sufficient cushioning properties and maintain portability. It is intended to do so.

[0007]

In order to solve the above-mentioned problems,
The structure of the present invention covers the front side of the body and is openable and closable.
And a lower part covering the back of the body
The lower part has a plurality of air tightness, and
Adjacent pipes made of deformable material
Provided in a state where they communicate with each other , and
Connected the air intake and exhaust ports
It is composed of cushioned shirafu .

[0008]

In the above construction, the lower part of the shirafu 1
In addition , a plurality of deformable pipes 5 capable of sealing air are used, and when used (at bedtime), air is sucked through the mouth 3 by an air pump as shown in FIG. When not in use, as shown in FIG. 2 (b), air is exhausted through the mouth portion 3, thereby exhibiting cushioning when used and portability when not in use. .

[0009] In Figure 2, a plurality of pipes 5 Odor
Te, the assumption that adjacent each other pipe are communicated with each other, the case of providing the one of the mouth portion 3, front
The mouth 3 for sucking and discharging the air is provided with a plurality of pipes 5.
May be provided in any of the above.

Rubber or synthetic resin is a typical example of a material that seals air and is deformable, but a plurality of pipes 5 are used when any part of the lower portion 11 is used. (In the case of one pipe 5, the central portion where the weight is concentrated is depressed as compared with the periphery thereof, so that stable cushioning cannot be exhibited.)

[0011]

In the embodiment , as shown in FIG. 4, there is shown a configuration in which a central portion of a plurality of pipes 5 constituting a lower portion is designed to be thick.

Normally, the body tends to concentrate its weight at the center of the lower part of the shirafu 1 at bedtime.
If the thicknesses are uniform, the central portion must be slightly sunk compared to the other portions.

However, when the central portion of the pipe 5 is designed deep as in the case of the embodiment, the central portion has a slightly raised shape from the periphery, and exhibits a relatively larger cushioning property than the peripheral portion. By,
It is possible to prevent the body from sinking as compared to both sides.

[0014]

The cushioning shirafu according to the present invention as described above can sufficiently exhibit the cushioning property and portability at the time of use (at bedtime).

Moreover, at the time of use (at bedtime), the lower portion is inflated by inhaling air,
Even when the ground is on a road and wet, water can be prevented from permeating, and sufficient sleep can be achieved.

As described above, the present invention has various advantages, and its value is enormous.

[0017]

[Brief description of the drawings]

FIG. 1 is a longitudinal sectional view showing a basic configuration of the present invention, in which (a) shows a state in which air is inhaled when used, and (b) shows a state in which air is exhausted when not in use. The state is shown.

FIG. 2 is a longitudinal sectional view showing the configuration of the embodiment.
