Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a camping mat which is low in volume and easily accommodated for easy carrying.

[0002]

2. Description of the Related Art Camping mats are used for mountain climbing, camping, etc. to keep warm and protect the body at bedtime. This is made by adhering an aluminum foil on one side of a sponge-like foam synthetic resin plate having a thickness of several mm, and making it have a length and width necessary for one or two people to lie down. It is cut, and it is rolled when carrying to reduce the bulk.

[0003]

[Problems to be Solved by the Invention] Since many items are carried in mountain climbing, camping, etc., it is desirable to keep the items as low as possible. For this reason, camping mats that can be rolled up are generally used. By the way, the thickness of the camping mat needs to be limited to about several mm in order to be easily collected and within the required bulk, but the camping mat may be laid directly on the ground. In many cases, a thicker mat is preferable from the viewpoint of moisture resistance and heat retention.
However, for the above-mentioned reason, the conventional camping mat cannot be made too thick, and since the aluminum foil is stuck on only one side, if the pebbles are exposed on the ground, There was a defect that the foil was damaged and the moisture-proof effect was reduced.

The present invention provides a camping mat which is convenient for carrying without being bulky even if the mat is thicker than the conventional product, and is capable of easily producing a durable camping mat having excellent heat retention and moisture resistance. An object of the present invention is to provide a method for manufacturing a mat for use.

[0005]

In order to achieve the above object, a method of manufacturing a camping mat according to the present invention comprises a sponge-like foamed synthetic resin plate having a required thickness and elasticity, and an aluminum foil on the surface. The synthetic resin woven fabric or sheet with the above is bonded to the mat material to form an integral unit, and one side of the front and back sides is alternately spaced from the other side, and the other side is made of synthetic resin. The point is to make a cut so that the woven cloth or sheet is not cut.

[0006]

[Function] The mat material is formed by making a gap between the front and back surfaces of the mat material alternately at the front and back surfaces, and making a cut so that the synthetic resin woven cloth or sheet on the other surface is not cut. It is possible to manufacture camping mats without special edge treatment. And the camping mat manufactured by this method,
It can be folded in a bellows shape through the synthetic resin woven cloth or sheet that remains without being cut, and the mat surfaces are in close contact with each other so that it is not bulky and convenient to carry. Since a synthetic resin woven fabric or sheet with aluminum foil on both sides is adhered, it is strong and has excellent heat retention and moisture resistance.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The camping mat of the present invention will be described below with reference to the illustrated embodiments. In the figure, reference numeral 1 denotes a foamed synthetic resin plate in the form of a closed cell or an open-celled sponge, which is obtained by foaming a required synthetic resin. The thickness is set to several mm to several tens of mm, and the width and length are defined so that one or two people can sleep side by side.

Then, a woven cloth or a sheet 2 woven of a synthetic resin which is the same as or different from that of the expanded synthetic resin plate 1 is welded to both the front surface and the back surface of the expanded synthetic resin plate 1. As the woven cloth or sheet 2, a thin tape-shaped synthetic resin woven material, a synthetic resin thread woven material, or a sheet having a required thickness is used, but is preferably as thin as possible.
Use one with high strength. As the woven cloth or sheet 2, an aluminum foil 3 is integrally stretched on the surface by welding, vapor deposition or adhesion.

Next, a synthetic resin woven cloth or sheet 2 having aluminum foil 3 on its surface is adhered to both front and back surfaces of the foamed synthetic resin plate 1 to form a mat material M, which is folded in a bulky manner, With a predetermined width of 1 pitch to make it convenient to carry, cuts 4, 5, ... Are made in a direction orthogonal to the longitudinal direction of the mat material. In this case, the cuts 4 are from the front surface side of the mat material M, and the cuts 5 are from the back surface side of the mat material, with the required intervals alternately on the front and back sides, and on the other surface (the surface opposite to the surface where the cut is made). ) The synthetic resin woven cloth or sheet 2 is inserted so as not to be cut. As a result, the mat material M cut at the cut lines 4 and 5 is
It can be folded into a bellows shape through the remaining synthetic resin woven cloth or sheet 2 without being cut, and the synthetic resin woven cloth or sheet 2 having an aluminum foil 3 on its surface is adhered to form one body. Since the mat material M is used, the mat material having the cuts 4 and 5 can be made a strong product having excellent heat retention and moisture resistance without special end treatment.

The camping mat constructed as described above is folded into a bellows shape to be a prismatic shape, which is fastened with a band or the like and carried.

[0011]

EFFECTS OF THE INVENTION According to the present invention, the synthetic resin woven fabric or sheet on the other surface is not cut from one of the front and back surfaces of the mat material alternately with the required spacing. By making the cut, it is possible to easily manufacture the camping mat without needing to perform a special end treatment only by making the cut on the mat material.
And, the camping mat manufactured by this method can be folded into a bellows shape through the synthetic resin woven cloth or sheet left uncut, and the mat surfaces are in close contact with each other as compared with the conventional winding type. It is convenient because it is not bulky, and because it is made of synthetic resin woven cloth or sheet with aluminum foil on both front and back sides of a sponge-like foam synthetic resin plate, it is strong and excellent in keeping heat and moisture. It becomes a thing.
