[0009] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. However, the components described in the following embodiment are merely examples, and are not intended to limit the technical scope of the present invention.

[0010] [First embodiment] An inflatable mat 100 as a first embodiment of the present invention will be described with reference to Fig. 1. As shown in Fig. 1, the inflatable mat 100 includes two sheets of urethane 101, 102, an aluminum vapor deposition film 103, a bag body 104, and a valve 105.

[0011] The aluminum vapor deposition film 103 is sandwiched between two sheets of urethane 101, 102. The bag 104 hermetically encases the two sheets of urethane 101, 102 and the aluminum vapor deposition film 103. The valve 105 opens and closes an intake and exhaust hole provided in the bag 104.

[0012] According to this configuration, an inflatable mat with high heat retention can be provided.

[0013] [Second embodiment] Next, an inflatable mat according to a second embodiment of the present invention will be described with reference to Figs.

[0014] The inflatable mat 200 is an automatic inflatable sleeping mat that, when placed under a sleeping bag or the like, serves to reduce unevenness on the ground and to block cold air from the ground. The inflatable mat 200 has urethane 201, 202 sealed in a bag 204 made of polyester or nylon fabric.

[0015] The urethane 201, 202 is a sponge-like urethane that has the property of shrinking when compressed and returning to its original shape when released. The urethane 201, 202 may have an air pocket structure for creating an air layer.

[0016] As shown in FIG. 2, the inflatable mat 200 includes two sheets of urethane 201 and 202 , an aluminum vapor deposition film 203 , a bag body 204 , and a valve 205 .

[0017] The aluminum-deposited film 203 is sandwiched between two sheets of urethane 201, 202 of the same thickness and made of the same material. The bag 204 hermetically encases the two sheets of urethane 201, 202 and the aluminum-deposited film 203. The valve 205 opens and closes an intake and exhaust hole provided in the bag 204.

[0018] The aluminum vapor-deposited film 203 is adhesively fixed to two sheets of urethane 201, 202. The two sheets of urethane 201, 202 are adhered to both sides of the aluminum vapor-deposited film 203 using, for example, a modified silicone elastic adhesive that does not contain cyclic siloxane.

[0019] The two sheets of urethane 201 and 202 may be made of urethane having different densities. The aluminum vapor deposition film 203 may be made of two layers, or three or more layers.

[0020] By sandwiching 0.5 mm aluminum vapor deposition film 203 between 2.5 cm urethane 201, 202, an R value (thermal resistance per unit area) of 6.9 was achieved. Conventional inflatable mats have an R value of about 3, so this is more than twice as warm.

[0021] The bag 204 is made of two sheets of polyester or nylon fabric that are heat-sealed around the periphery, and the surface of the sheets is brushed for a pleasant feel against the skin.

[0022] Fig. 3 is a diagram for explaining the state of the inflatable mat 200 according to this embodiment when it is stored. When storing the inflatable mat 200, the air stored in the internal urethanes 201, 202 is discharged while being compressed. For this reason, as shown in Fig. 3, the valve 205 is opened, and the end part away from the valve 205 is rolled up inward to squeeze out the air inside the inflatable mat 200. At this time, the weight of the body is used to firmly release the air and compress the mat, which determines how compact it becomes when stored. Once it has been folded up small, the valve is closed and it is returned to the storage bag.

[0023] When setting up the inflatable mat 200, it will automatically expand due to the restoring force of the urethane 201, 202, so all you have to do is take it out of the storage bag, open the valve 205, and wait. Once it has inflated to a suitable level of firmness, close the valve and begin using it. The inflatable mat 200 provides a comfortable sleep because the air-filled urethane 201, 202 maintains its shape, and the aluminum vapor deposition film enhances heat retention.

[0024] To improve air flow, holes may be provided in the aluminum deposition film 203. The density of the holes may be changed according to the distance from the valve. For example, the density of the holes may be increased as the distance from the valve increases.

[0025] It is also possible to change the hardness of the urethane 201, 202 depending on the location. This can further improve the comfort of sleeping. The hardness or thickness of the urethane 201, 202, or both, may be changed. In this case, it is sufficient to change which side of the inflatable mat 200 is used up depending on the situation or preference.

[0026] Furthermore, two sheets of urethane with multiple protrusions or irregularities on only the front surface may be prepared, and an aluminum deposition film 203 may be sandwiched between the back surfaces of both sheets to form the inflatable mat 200. This makes it possible to realize an inflatable mat that combines heat retention, shape stability, and durability.

[0027] [Other embodiments] Although the present invention has been described above with reference to the embodiments, the present invention is not limited to the above embodiments. Various modifications that can be understood by those skilled in the art can be made to the configuration and details of the present invention within the technical scope of the present invention. In addition, systems or devices that combine the separate features included in each embodiment in any way are also included in the technical scope of the present invention.
