DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The sheet-like body according to the present invention can be used for household articles, health articles, recreational articles, etc., such as clothes worn daily, clothes worn during exercise, hats, It is applicable to footwear and insoles of footwear, seats for chairs used in homes, offices, automobiles, beds, etc., and more specifically, to press the sheet-like body with a part of the body or object. The air inside is discharged toward the pressurized part, so that you can feel a cool sensation, etc., or by inhaling the air when pressurized, you can simultaneously inhale dust etc. Regarding the body

[Prior Art] As is well known, the sheet-like body is a paper, a woven fabric, a non-woven fabric or the like, and is widely used for daily life articles and the like. Usually these do not have air chambers between the front and back sheets,
Depending on the application method used, cushioning, heat retention,
In some cases, cold insulation is required, and various measures have been taken, such as using a double structure.

Focusing on the above-mentioned double-structured sheet-like body, non-air-permeable sheets are used for the front and back sheets, and by sealing the ends of the sheets, an air chamber can be provided between the front and back sheets to provide cushioning and heat retention. -It can be made into a sheet-like body having a cold insulating property. However, since non-breathable sheets are used for the front and back sheets, problems such as stuffiness of the contact surface with the body or object occurred, so when pressurized by the body or object, the double structure When air in the air chamber is discharged to the contact portion or pressurized, it is required to inhale the air. Therefore, conventionally, a method by mechanical operation has been considered. That is, a valve is provided on either surface of the front and back sheets, a sensor or the like detects that a body or an object hits the front or back sheet and is pressurized, and the valve is operated by the operation of a cylinder or the like. Is opened, air in the inner air chamber is discharged to the front and back sheet surfaces, or it is detected that pressure is applied so that air is sucked.

[Problems to be Solved by the Invention] However, air release and intake in the air chamber by the above mechanical mechanism require sensors, valves, cylinders, etc., and it is impossible to reduce the cost for downsizing, valves and seats. It was practically impossible in practical use due to the problems such as the durability of the joint portion and the hardness of the mechanical member which may cause a contact failure.

[Purpose] Therefore, the present invention has cushioning properties, heat retention and cold retention properties,
Moreover, when the air in the air chamber between the air-impermeable sheets on the front and back is released to or pressed on either side of the pressurized front and back sheets without using a mechanical mechanism, air is drawn into the air chamber. It is to provide a sheet-like body that can be manufactured.
In addition, the above-mentioned object is made possible while ensuring soft contactability when the body or object is pressed.

[Means for Solving the Problems] In the present invention, the following technical means are used to solve the above problems. That is, referring to the reference numerals used in the accompanying drawings corresponding to the embodiments, the present invention comprises a pair of non-breathable front and back sheets 1 and 2, and a pressure is applied between the front sheet 1 and the back sheet 2. By this, a pair of front and back sheets 1, 2
In the sheet-shaped body A, which discharges the air in the air chamber 3 formed between them to the front or back sheet surface or sucks the air into the air chamber 3 when pressurized, A plurality of valve chambers 4 made of an elastic material for shutting the air chamber 3 from the outside in the air chamber 3 between the pair of front and back sheets 1 and 2 are arranged at predetermined intervals so that the air chamber 3 between the valve chambers 4 remains. And the valve chambers 4 are partly opened, and a part of each valve chamber 4 is opened to the front or back seat surface, and the valve chambers 4 are arranged on the wall surface of each valve chamber 4 in contact with the air chamber 3. When elastically deformed by pressurizing the front sheet 1 or the back sheet 2 by the pressure between the sheets 1 and 2, it opens and is applied to the front or back sheets 1 and 2. The sheet-like body is characterized in that when the valve chamber 4 is restored to its original state by releasing pressure, an opening / closing cut 5 is formed. Thus, the valve chamber 4 may be restored by its own bullet restoring function, or may be restored with the help of the restoring function of the auxiliary bullet restoring member.

[Operation] Since the present invention is composed of the above technical means, the air chamber 3 is provided between the pair of non-air permeable front and back sheets 1 and 2.
Has cushioning and heat / cold retention properties. The valve chamber 4 provided in the air chamber 3 at a predetermined interval and opened on the front or back seat surface and having the opening / closing cut 5 formed therein allows the front and back of the sheet-like body A to be covered. When the space between the seat surfaces is pressed, the opening / closing cut 5 is opened and the air in the air chamber 3 can be discharged to the surface of the pressed front or back sheet-like body, and a cool feeling or the like can be felt. . Also, when pressurized, the air chamber 3
Since air is sucked in, dust and the like can be sucked in at the same time, so that the surface of the sheet-shaped body can be kept clean. In this case, intake means is attached.

Further, since the valve chamber 4 is made of an elastic material, it has cushioning properties, and in addition, it is possible to secure the durability of the joint portion with the front and back sheets 1 and 2, and further, to secure the durability of the front and back sheets 1 and 2. Since no mechanical mechanism is required between them, the cost can be easily suppressed.

[Embodiment] Next, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. In this embodiment, an example is shown in which air is released from the air chamber when pressurized.

FIG. 1 is an overall perspective view of the sheet-shaped body of the present invention, and FIG. 2 is a sectional view taken along the line II 'in FIG. 1, showing the structure of the sheet-shaped body.

In the sheet-shaped body A, an air chamber 3 is formed between a front sheet 1 and a back sheet 2, and in the air chamber 3, valve chambers 4 are arranged in an appropriate distribution.

The sheet 1 on the front side and the sheet 2 on the back side are non-air-permeable sheets such as non-woven fabric, and seal the air chamber 3 by welding or fusing the end portions 6 to seal them.

The valve chamber 4 is made of an elastic material and has a diameter of 5-10, for example.
It has a spherical shape of mm. A plurality of the air chambers 3 are distributed at a predetermined interval so that the air chambers 3 remain, and the air chambers 3 are opened on either one of the front and back sheet surfaces. Further, on the wall surface of each valve chamber 4 in contact with the air chamber 3, the opening / closing cut 5
Are formed. The opening / closing notch 5 is formed when the valve chamber 4 is elastically deformed by pressing between the front and back sheets 1 and 2, that is, by pressing the front sheet 1 and the back sheet 2. It is formed so as to open when the valve chamber 4 is restored to its original state by releasing pressure to the front and back sheets 1 and 2.

Next, the operation will be described. As shown in FIG. 3, when the sheet-like body A is pressed against the body or the object (in this embodiment, the sheet 1 side in the table is pressed), the air chamber 3 in the sheet-like body A is pressed. The valve chamber 4 made of the elastic material is elastically deformed inside, and the opening / closing cut 5 provided in the valve chamber 4 is opened. Therefore, the air sealed in the air chamber 3 is discharged to the valve chamber 4 through the open / closed cut 5, and further to the outside from the opening 7 to the seat surface of the valve chamber 4. And sheet A
When the pressure on the valve is released, the valve chamber 4 returns to its original state,
The opening / closing cut 5 is opened and the air chamber 3 is sealed, and the front sheet 1 returns to the position before being pressurized, that is, the line II-II 'in the figure.

Therefore, the sheet-shaped body A of the present case is composed of a pair of front and back sheets 1, 2
Since the air chamber 3 and the valve chamber 4 are provided between them, not only the heat retention / cooling property but also the cushion property can be provided.

When the sheet A is pressurized from the front or back to the other side, the air in the air chamber 3 is discharged from the valve chamber 4 to the pressurized portion, so that a cool sensation can be obtained. Further, when the pressurization is released, air may be sucked into the air chamber 3, and at the same time, dust or the like can be sucked in and the seat surface can be kept clean. Further, by arranging the valve chambers 8 not provided with the opening / closing cuts 5 in some places between the valve chambers 4 and opening them in the front and back seat surfaces, it is possible to ensure the air permeability between the front and back surfaces. Moreover, the valve chamber 8 itself may be used as an auxiliary bullet restoring member, and in this case, the restoration of the front and back sheets 1 and 2 is assisted by the restoring function of the valve chamber 8. Further, a mechanical spring may be used instead of the valve chamber 8.

FIG. 4 is an arrow view when the sheet-like body A of the present case is used for a seat B of an automobile, and when a driver or a passenger sits on the seat B, a feeling of coolness is felt, and heat insulation / cooling property is obtained. And has cushioning properties.

FIG. 5 is a cross-sectional view of the sheet-like body A and shows an example of the manufacturing method thereof. That is, in the figure, it is divided into a front side 11 and a back side 12 by the line III-III ', half of the seat and the valve chamber 14 are integrally molded, and they are joined by the line III-III' by bonding or the like to form a sheet-like body. A is formed, and the sheet-like body A can be formed more easily than in the case where the spherical valve chambers 4 are individually formed and joined, and the cost can be easily suppressed.

Although the front and back sheets are made of non-woven fabric in the example, the present invention is not limited to this, and other non-breathable sheets may be used. The valve chamber 4 may be made of plastic, rubber, or the like, but the elastic restoring material is not limited to the plastic, rubber, or the like, and the shape thereof is not limited to the spherical shape and the size is 5 to 10 mm. However, this is not the case.
When the air is sucked into the air chamber from the outside when it is pressurized, an intake means is associated with it.

[Effects] As described in detail above, the present invention provides an air chamber and a valve chamber between a pair of non-breathable front and back seats, so that heat and cold insulation can be achieved.
Has cushioning properties. In particular, when the sheet-shaped body is pressed against a human body or an object, the air in the air chamber is discharged through the valve chamber through the front or back openings of the seat, so that a cool sensation and the like can be obtained and a feeling of use is improved. When pressurized, air is sucked into the air chamber, so that dust and the like can be sucked in at the same time, and the surface of the sheet-shaped body is kept clean. Also, since the valve chamber is made of elastic material, the durability of the joints with the front and back seats can be ensured, and moreover, no mechanical operating means is required at the time of releasing and inhaling air, so the cost is reduced. It has the advantage of being easy. Furthermore, since no mechanical valve structure is used, the contact with the human body and objects becomes soft.
