DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a foldable mat which is bulky and can be easily folded, and which is easy to carry and store.

[0002]

2. Description of the Related Art Conventionally, camping mats have been used for climbing, camping, and the like, to keep the body warm and protected when sleeping. This camping mat has an aluminum foil stuck on one side of a sponge-like foamed synthetic resin plate having a thickness of several mm, and has a length and width necessary for one or two people to lie on it. It is cut in such a way that it is rolled up when carrying to reduce its bulk.

[0003]

There are many items to carry in mountain climbing, camping, and the like. Therefore, it is desirable that the items to be carried are as low as possible. For this reason, camping mats that can be generally wound up are employed. By the way, in order to be able to be easily wound up and within the required bulk, it is necessary to suppress the thickness of the camping mat to about several mm, but the camping mat may be laid directly on the ground. In many cases, a thicker mat is desirable from the viewpoint of moisture prevention and heat retention.
However, conventional camping mats could not be made too thick for the above reasons.

The present invention has been made in view of the above problems of conventional mats, and has been developed to provide a durable, foldable mat which is easy to carry and store without thickening even if the mat thickness is increased. It aims to provide a manufacturing method.

[0005]

In order to achieve the above object, a method for manufacturing a foldable mat according to the present invention comprises a sponge-like foamed synthetic resin plate having a required thickness and elasticity on both front and back surfaces of a woven fabric or a woven fabric. A cut is made in the mat material that is made by bonding the sheets together from one side of the front and back sides, leaving a required gap between the front and back sides alternately, and so that the woven fabric or sheet on the other side is not cut off. It is characterized in that it can be folded in a bellows shape via a woven fabric or sheet left uncut.

[0006]

[Function] By making a cut from one side of the front and back sides of the mat material at a required interval alternately, and cutting the woven fabric or sheet on the other side,
A foldable mat can be manufactured without special edge treatment of the mat material. And
The mat manufactured by this method can be folded in a bellows shape through the woven fabric or sheet remaining without being cut, and the mat surfaces are in close contact with each other and are not bulky, so it is convenient for carrying, storing, and the like. Since the woven fabric or sheet is adhered to both the front and back surfaces of the sponge-like foamed synthetic resin plate, the sponge-shaped foamed synthetic resin plate is durable and excellent in heat retention and moisture proof.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A method of manufacturing a foldable mat according to the present invention will be described below with reference to the illustrated camping mat. In the figure, reference numeral 1 denotes a sponge-like foamed synthetic resin plate in which a required synthetic resin is foamed to form a closed cell or an open cell. The foamed synthetic resin plate 1 has an appropriate elasticity and heat insulating property even if it is placed on the foamed synthetic resin plate. The thickness is set to several mm to several tens of mm, and the width and length are determined so that one or two persons can sleep side by side.

A woven fabric or sheet 2 made of synthetic resin of the same or different quality as the foamed synthetic resin plate 1 is welded to both the front and back surfaces of the foamed synthetic resin plate 1. As the woven fabric or sheet 2, a woven thin tape of synthetic resin or a woven synthetic resin thread, or a sheet of a required thickness is used.
Use the one with high strength. The woven fabric or sheet 2 used is one in which an aluminum foil 3 is integrally attached to the surface thereof by welding, vapor deposition or adhesion.

Next, a mat material M formed by bonding a synthetic resin woven fabric or sheet 2 having an aluminum foil 3 on its surface to the front and back surfaces of the foam synthetic resin plate 1 to form an integral unit is folded low in volume. The cuts 4, 5,... Are made in a direction orthogonal to the longitudinal direction of the mat material, with a predetermined width as one pitch so as to make it easy to carry and store. In this case,
The cut 4 is from the front side of the mat material M, and the cut 5 is the synthetic resin on the other surface (the surface on the opposite side to the cut surface) with a required space between the front and back surfaces alternately from the back surface of the mat material. Woven fabric or sheet 2 is inserted so as not to be cut. Thereby, the mat material M cut at the cuts 4 and 5 can be folded in a bellows shape via the synthetic resin woven fabric or sheet 2 left uncut, and
Since a mat material M made by bonding a synthetic resin woven fabric or a sheet 2 having an aluminum foil 3 on its surface to be integrated is used, a special end portion is provided for the mat material having cuts 4 and 5. It is possible to make a product that is durable and has excellent heat insulation and moisture proofing without treating.

The camping mat constructed as described above is folded into a bellows shape and turned into a prismatic shape, and is carried or stored by fastening with a band or the like.

[0011]

According to the present invention, a cut is made from one of the front and back surfaces of the mat material at a required interval alternately between the front and back surfaces, and so that the woven fabric or sheet on the other surface is not cut. Thereby, it can be folded in a bellows shape through the woven fabric or sheet remaining without being cut. Thus, it is not necessary to perform a special edge treatment only by making a cut in the mat material, and a foldable mat can be easily manufactured. Then, the mat manufactured by this method can be folded in a bellows shape through the woven fabric or sheet remaining without being cut, so that the mat surfaces are more closely adhered to each other than the conventional winding type and do not bulk. It is convenient for carrying, storing, etc., and since a woven fabric or a sheet is adhered to both front and back surfaces of a sponge-like foamed synthetic resin plate, it is durable and excellent in heat insulation and moisture proof.
