Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 7 are views showing the configuration of the portable cushion 10 to be provided by the present invention, and FIGS. 8 to 14 are views showing the portable cushion 10 of another embodiment, the seat plate 20 and , a cushion 40 and a cover 60 .

The seat plate 20 is injection-molded with synthetic resin, and a "U"-shaped curved concave indent 22 is formed in the center of the main body 21 constituting the seat 20, and the curved concave portion 22 is located in the front center and outer peripheral surface. A curved protrusion 23 is formed.

In addition, the side plate 24 is formed on the edge of the main body 21, and the coupling protrusions 25 are formed on the bottom surface of the side plate 24 at equal intervals.

By placing the base plate 26 on the lower side of the main body 21 constituting the seat plate 20, and then the engaging protrusion 25 of the side plate 24 is coupled to the engaging hole 27 drilled in the edge of the base plate 26, The bottom plate 26 is assembled to the bottom surface of the seat plate 25 .

When the base plate 26 is assembled on the bottom surface of the main body 21 of the seat plate 20 as described above, the bottom surface of the side plate 24 and the curved recess 22 of the seat plate 20 comes into contact with the base plate 26 and the seat plate The main body 21 of (20) is prevented from sagging downward, and since the lower space 43 is formed between the bottom plate 26 and the seat plate 20, it serves as both a cushioning function and a heat insulating function.

The cushion material 40 is covered on the upper surface of the seat plate 20 to which the bottom plate 26 is assembled, so that an upper space 41 is formed between the cushion material 40 and the body 21 of the seat plate 20, and the cushion material 40 On the outer surface of the seat plate 20 covered with , a cover 60 that opens and closes again with a slide fastener 61 is placed so that the cushion material 60 is wrapped, and then the portable cushion 10 of the invention is fixed by binding with the slide fastener 61. it is composed

Therefore, in the portable cushion 10 to be provided in the present invention, the cushioning material 40 is put on the seat plate 20 and then the cover 60 is put on again to be bound and fixed with the slide fastener 61, so that the seat plate 20 is placed on the seat plate 20. The positioned cushioning material 40 is stably fixed.

At this time, the material of the cushioning material 40 may be used in various forms, such as a compressed sponge, foamed resin, or a mat filled with air or water in a plate-shaped tube.

In addition, in binding and fixing the cover 60 covered on the outer surface of the seat plate 20 and the cushioning material 40, the binding hole ( 63) may be drilled, and the binding may be fixed using the binding string 64 .

In practicing the present invention, a separate inner cushioning material 40-1 may be additionally installed and used in the upper space 41 configured between the seat plate 20 and the cushioning material 40 as shown in FIGS. 13 to 14 . .

The seat plate 20 constituting the portable cushion 10 has different sizes, such as large, medium, and small, so that it can be selected and used according to the user's physique, and at the same time, the cushioning material 40 and the inner cushioning material installed on the seat plate 20 The thickness of (40-1) is also thick and thin, and you can choose to use it.
