JPS6010439Y2 - Pine tress for both summer and winter use - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to a pine tress for both summer and winter use.

Recently, core materials for bedding have been produced in which a number of cylindrical or columnar core materials are arranged in wooden blocks, or in which a number of cylinders are arranged in parallel by placing them in a symmetrically continuous outer bag tube. Various types have been developed.

However, as shown in FIG. 1A, conventional devices have the same uneven shape on the front and back, and have the disadvantage that they are cool in the summer but cold in the winter due to drafts passing through them.

Further, when used in an outer jacket bag 2 as shown in FIG. IB, the passage of drafts can be suppressed to a certain extent, making it warm in winter, but conversely making it hot in summer.

Furthermore, as shown in Figure IC, when used as a three-piece pine tress, the joints between the pine tress pieces are depressed, which impairs the appearance and makes sleeping uncomfortable.Moreover, the upper and lower ends are rounded, so the pillow may slip off or the comforter may It has the disadvantage that it slips off.

The present invention aims to overcome these drawbacks by combining a flexible columnar core material with a substantially circular, oval or polygonal cross section into a plurality of cylindrical objects or cylinders that are joined to a sheet-like object in some cases. To provide a summer/winter pine tress in which both ends of the cylindrical object or the storage opening of the cylindrical bag are closed after the outer cover to which the shaped bags are connected is stored in each of the cylindrical objects or the cylindrical bag. It is.

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

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

For example, as shown in FIG. 2A, the outer cover is made by sewing (melting or gluing) 5 pieces of cloth or sheets 3 at appropriate intervals so that the cylindrical objects 4 are continuous.

As another example, as shown in FIG. 2B, another cloth or sheet piece 6 is sewn (fused or Adhesion) 5.

After storing the core material inside each cylindrical object, both ends are sewn, glued,
Close with fusing, zipper, adhesive tape, etc.

In addition, when it is configured as a bag-like article with one end closed in advance, the accommodation opening may be closed after the core material is accommodated.

The pinerest of the present invention can be used not only as a one-piece pinetress but also as a split pinetress, 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

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 cylinder 8a having wart-like protrusions 7 over the entire surface, and is attached to an outer cover 9. 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 and 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 9.

FIG. 6 shows a flexible columnar structure made of a composite body in which two U-shaped foamed plastic molded bodies 15 each having a wart-like protrusion 7 and a through hole 14 at the top are interlocked with each other so that a hard plastic pipe core 16 is sandwiched therein. A flexible columnar core material is made by wrapping a composite sheet (e.g. Air Cap: a product name of Ube Industries, Ltd.) 17 with many independent convex air chambers and polyurethane foam 18 and covering it with an outer cover 9. Here is an example of packaging.

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 9. 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 below.

Figure 9 shows the flexible columnar core material 1 stored at both ends of the pine tress.
This is an example in which the cross-sectional shape of the core material is approximately semicircular, and the flat surface is placed on the outside, so that the outside of the core material is substantially flat.

This prevents pillows and comforters from slipping off,
Furthermore, even when the pinerest is made into a three-piece pinerest, no dents are formed at the joints of the pinetress pieces, so the product value and sleeping comfort are not compromised.

Note that the same effect can be achieved using a rectangular column as the core material.

If the pinetress of the present invention is used with the sheet-like material side facing up as shown in FIG. 10, the depressions formed between adjacent core materials will be covered by the sheet-like material.

Therefore, the vertical air flow that directly reaches the human body is blocked, making it warm and suitable for use in winter.

On the other hand, when using the sheet with the side not in contact with it facing up, the air circulation comes into direct contact with the human body, making it cooler.
Comfortable for summer use.

Incidentally, a sense of stability can be increased by attaching Velcro, double-sided adhesive tape, etc. to the side surface of the tubular object or the tubular bag to secure the adjoining tubular object housing the core material (FIG. 11).

Alternatively, it may be fixed in a highly breathable material, for example, a net-like outer bag.

The present invention uses a flexible columnar core material with a transom or polygonal cross section, so unevenness occurs between adjacent core materials.The convex part exerts an acupressure effect, and the concave part improves air permeability. Always keep the pine tress in a sanitary condition.

In addition, by combining this with wart-like projections, convex air chambers, etc., you can expect a more delicate acupressure effect, and by combining it with flexible materials such as polyurethane foam and cotton, you can achieve the desired cushioning effect. We can provide winter-use pine tresses.
