Description

[Detailed description of the invention] This invention is concerned with improving the constituent materials of sleeping bags, bedding, clothing, etc.

Conventional materials for sleeping bags, bedding, and clothing are made by layering a heat insulating material such as feather, cotton, or synthetic cotton between two pieces of cloth, and then forming a cover fabric, a heat insulating material, and a lining fabric. Cotton tacking that goes through the
Alternatively, it was constructed by forming it into a ring.

In such known constituent materials, cotton or synthetic cotton is interlayered between the front and lining fabrics, so if the insulation material in the cotton fastening part or ring fastening part is a cotton layer, it will not be compressed. If it is a feather layer, the feathers will escape from the cotton-stitched part or the ring-stitched part, and the front and back fabrics of the cotton-stitched and ring-stitched parts will be in direct contact with each other and fastened together. As a result, the warm air inside the components escapes from this part, allowing cold air to enter the outside.

This idea involves interposing several cushion bodies at intervals between two sheet-like materials, and by fixing them to the two sheet-like materials, the inner surfaces of the two sheet-like materials, the cushion bodies By filling the heat insulating material filling chamber formed by the thick wall surface with the heat insulating material from the side opening of the chamber to form the constituent materials of sleeping bags, bedding, clothing, etc., the cushioning material can be placed between the two sheets. When fixing the material, even when it is sewn and fixed, there is no compression escape of the heat insulating material as in the conventional method, which increases the heat insulating effect, and it is easy to fill the heat insulating material, and it can be filled sufficiently to meet the needs. This makes it possible to swell up accordingly and evenly fill every nook and cranny, creating an average heat retention effect in every part, yet the cushion body part and the heat insulating material part feel different. The purpose is to provide constituent materials for sleeping bags, bedding, clothing, etc.

This invention will be explained as follows with regard to the embodiment shown in the drawings.

A rod-shaped cushion body 3, for example, is placed between a sheet-like material 1 made of a fabric, non-woven fabric, synthetic resin sheet, etc. that forms the front material, and a sheet-like material 2 made of the same material as the front material that forms the backing material or a different material. Several cushions made of urethane foam, non-woven fabric, felt, etc. are interposed between the cushion bodies 3, 3.3, and two cushions and the sheet materials 1, 2 are placed between the cushion bodies 3, 3.3. The inner surface is fixed by gluing, sewing, heat-pressing, or other means.

In this way, a heat insulating material 5 made of feathers, cotton, synthetic cotton, etc. is filled into the heat insulating material filling chamber 4 formed by the inner surfaces of the two sheet-like materials 1 and 2 and the thickness of the cushion bodies 3 and 3. do.

The cross-sectional shape of the cushion body can be square, rectangular, oval, or circular.

As shown in the figure, the chamber configured in this manner is formed into a sheet-like material filling chamber formed by the sheet-like materials 1 and 2 and the side surfaces of the cushion bodies 5 and 5 due to the uniform thickness of the cushion bodies 5 and 5. Since the inner surfaces of the materials 1 and 2 are uniformly spaced, when the heat insulating material 5 is filled into the material, it is evenly filled to every corner, and the thickness of each part is approximately uniform, making the cushion body 5. Even if the sheet materials 1 and 2 and the cushion body 5 are sewn together as shown in FIG. Therefore, since the constituent materials are formed to have an average thickness, the appearance seen from the outside is good, and every part produces an average heat retention effect.

In addition, when the three parts of a shoe are sewn and fixed to two sheet-like materials, the cushion body in those parts is compressed, but when the cushion body is made of closed cell foam, heat insulating air is released from the compressed part. There is no possibility of cold air escaping through the sewn parts, and cold air will not enter from the parts.

Furthermore, since the width of the cushion body can be adjusted arbitrarily, when using a wide cushion body, the heat insulating material filling chamber 4 can be made narrower, and therefore the amount of heat insulating material filled with feathers, cotton, synthetic fibers, etc. can be reduced. , the construction materials can be made cheaper.

As mentioned above, when fixing the cushion body to two sheets, even if the cushion body is fixed by sewing, the sewing will be done at the cushion body part, and the insulation material will not be sewn directly. Therefore, there is no compression or escaping of the heat insulating material in the sewn parts, which is the case with conventional structural materials, which increases the heat insulating effect.
The heat insulating material filling chamber, which is made up of the inner surfaces of the two sheets and the side surfaces of the cushioning material, can form an accurate rectangle.
Since the heat insulating material is uniformly filled throughout and the thickness of the constituent materials can be made uniform, an average heat insulating effect can be obtained.

Furthermore, the amount of heat insulating material used can be reduced by the amount of cushioning material interposed, saving expensive heat insulating material, resulting in an inexpensive component.

Furthermore, by making the hardness of the cushion body approximately equal to that of the heat insulating material, it is possible to obtain constituent materials such as sleeping bags, bedding, clothing, etc., which have a comfortable feel between the cushion body portion and the heat insulating material portion.
