It is a schematic perspective view showing an example of use of the convenient mat.

The present invention relates to a multipurpose pneumatic convenience mat capable of widely adjusting the degree of cushioning property, and as shown in FIG. 1, a front surface sheet 1a or a rear surface sheet of a closed independent air chamber 1. A fluid inlet / outlet 2 having a plug 2a is provided at at least one position of 1b, and a stop portion 3 welded to each other by an enclosing seal is formed at a substantially central portion of the top sheet 1a and the back sheet 1b. A welded portion 4 is formed on at least one edge of the above, and one edge of another independent air chamber 1 is welded to the welded portion 4 to continuously extend a plurality of independent air chambers 1.

That is, the independent air chamber 1 of the present invention uses a synthetic resin sheet having a gas barrier property and a waterproof property, in which both open ends of a tubular sheet are welded, or one sheet is used. Any manufacturing method can be used as long as it is a closed bag-like structure that does not leak air, such as one that is bent in one piece and welded on three sides, or one that is formed by welding the periphery of two sheets into a rectangular shape. Although any method such as heat sealing or ultrasonic welding may be used as the welding method, in the illustrated embodiment, one sheet is bent into two and the three sides are welded. It is a thing.

The fluid inlet / outlet 2 is provided in at least one position of the top sheet 1 a or the back sheet 1 b of each independent air chamber 1, and is for pouring / injecting air into / from the independent air chamber 1. The plug 2a provided in the fluid inlet / outlet 2 has a structure in which the fluid inlet / outlet 2 is closed by inserting a columnar body that is in close contact with the inner circumference of the cylinder into the inside of the cylinder through a connector at the upper end of the cylinder. The fluid inlet / outlet 2 will be buried in the cushion bag sheet when the multipurpose pneumatic convenient mat is inflated together with the plug 2a.
