Description

[Detailed explanation of the idea] The present invention relates to pine tress.

Recently, various types of bedding core materials have been developed, each of which has a plurality of consecutive cylindrical or oval cylindrical core materials.

For example, Utility Model Publication No. 50-2173 involves wrapping a plastic film having a large number of independent air chambers into a round rod shape, folding one sheet of cloth or plastic film over it, or overlapping two sheets to form lines at multiple points at regular intervals around the waist. This disclosure discloses a core material for a futon in which a large number of cylinders made by sewing or welding are housed in a continuous cylinder of an outer bag, and then both ends are sewn or welded.

However, as shown in Figures IA and B, in this case, each node is divided by points (from the side) or lines (from the plane) of the upper and lower cloth or plastic films, so each round rod-shaped object is It has the disadvantage that it tends to move wobbly and is therefore unstable in the pancreas, leaving a feeling of fatigue.

The present invention solves these drawbacks by housing a flexible columnar core material with a substantially circular or polygonal cross section inside an outer cover consisting of a plurality of consecutive cylindrical bags partitioned by gusseted cloth. After that, the pine tress is provided by closing the storage opening.

The flexible columnar core material having a substantially circular, oval or polygonal cross section may be, for example, a foam molded product of plastic such as polyethylene foam or polystyrene foam, or a composite of these and other elastic materials such as polyurethane, cotton, etc. Gives favorable results.

The outer cover is preferably cloth, a plastic sheet, a perforated plastic sheet, or the like.

For the outer cover, for example, as shown in FIG. 2A, first make a large bag-like material 4, and then gusset cloth 5 is sewn (fused or glued) 2 on the top and bottom. Another example is as shown in FIG. 2B. As shown,
By sewing (fusion bonding or gluing) 2 a gusset cloth 5 to a piece of cloth or sheet 6, an outer cover in which cylindrical bags partitioned by the gusset cloth are connected is made.

After storing the core material in each cylindrical bag, the storage opening is sewn, glued,
Close with fusing, zipper, adhesive tape, etc.

The pinerest of the present invention can of course be used as a single piece, but it is also used as a split pinerest, usually a three-piece pinetress.

Hereinafter, embodiments of the present invention will be described based on the drawings.

FIG. 3 shows a flexible columnar core material made of a foamed plastic columnar body 8a having wart-like protrusions 7 on a part of its surface.
This is an example in which it is accommodated in b.

FIG. 4 shows a flexible columnar core material made of a composite material in which polyurethane foam 10 having continuous mound-shaped ridges is bonded to the surface of a foamed plastic columnar body 8a having wart-like protrusions 7 over the entire surface, and is attached to an outer cover 9b. An example is shown below.

FIG. 5 shows a flexible columnar core in which a cotton laminate 13 is bonded to the surface of a foamed plastic hexagonal columnar body 8b, which has grooves 11 on its surface to form an uneven shape and wart-like protrusions 7 on the convex-shaped portions 12. This is an example in which the material is covered with an outer cover 9b.

FIG. 6 shows a flexible composite body in which two U-shaped foamed plastic hollow bodies 15 each having a wart-like protrusion 7 and a through hole 14 at the top are interlocked so that a hard plastic pipe core 16 is sandwiched therein. Composite sheet with a columnar core material and many independent convex air chambers (e.g. Air Cap: trade name of Ube Industries, Ltd.) 17 and polyurethane foam 18
An example is shown in which a flexible columnar core material is wrapped with an outer cover 9b.

FIG. 7 shows an example in which a flexible columnar core material obtained by winding together a composite sheet 17 having a large number of independent convex air chambers and a polyurethane foam 18 around a hard plastic pipe core 16 is housed in an outer cover 9b. It is.

FIG. 8 shows a flexible columnar core material in which the surface of a foamed plastic columnar body provided with wart-like protrusions 7 is wrapped with polyurethane foam 18 and a composite sheet 17 having a large number of convex air chambers is wrapped around the outer surface. An example is shown in which it is housed in 9b.

According to the present invention, since flexible columnar core materials having substantially the same, circular, or polygonal cross sections are used, unevenness occurs between adjacent core materials, and the convex portions exert an acupressure effect while the concave portions improves ventilation and keeps the pine tress in a sanitary condition at all times.

In addition, by combining this with wart-like protrusions, convex air chambers, etc., a more delicate acupressure effect can be expected, and by combining it with flexible materials such as polyurethane foam and cotton, a desired cushioning effect can be expected. is possible.

Furthermore, by combining the outer cover with the special structure of the present invention, the point or line contact of conventional products can be changed to surface contact, thus ensuring a stable and comfortable sleep with almost no feeling of wobbling. .
