Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a core material for a pillow which is applied to the head or waist, buttocks, feet or legs to recover or reduce fatigue of each part.

[0002]

2. Description of the Related Art As a material for a pillow for sleeping, feathers, synthetic cotton, sponge, ceramics, plastics, etc. are used in addition to buckwheat hulls which have been widely used since ancient times, and they are wrapped in a cover. In addition, there is one using a core material having a shape suitable for supporting the head without giving an excessive force to the cervical spine. Furthermore, even when sitting for a long time, a waist pillow has been manufactured to protect the waist. This is a cover made of a synthetic resin material or an air bag shaped to fit the outer shape of the waist.

[0003]

Therefore, the conventional pillows have different shapes for head and waist applications, and are incompatible with each other.
Furthermore, the shape retention is poor.

The present invention is a pillow which is easy to manufacture and can be used in one shape for different purposes such as head, neck, waist, buttocks, legs, feet, etc. The purpose is to provide a core material.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to achieve the above object, and is characterized in that a large number of columnar members made of foamed resin are rotatable in the circumferential direction and fixed to each other. . The gist is that the columnar body has a circular cross section or a hexagonal cross section. Further, the gist of the present invention is to dispose a plurality of columnar bodies on the outer peripheral portion of the central columnar body in the circumferential direction thereof and fix them to each other so as to be integrally rotatable.

[0006]

[Operation] Since a large number of columnar bodies made of foamed resin are rotatably in the circumferential direction and fixed to each other, in addition to the head, for the waist, buttocks, legs and feet Can be used as well, and the body surface or a flat portion and a corner portion can be brought into contact with each other, and can be used according to the application.

[0007]

The core material of the pillow of the present invention will be described below with reference to the embodiments shown in the drawings. In the figure, 1 is a columnar body made of foamed resin, and the cross-sectional shape is not only an arc shape but also a hexagonal shape and other polygonal shapes, and this is cut to an appropriate length as a pillow. Polyethylene, polypropylene, semi-rigid polyurethane, or the like is used as the material of the foamed resin columnar body 1. Since the foamed resinous columnar body 1 has appropriate elasticity and resilience as a pillow core material, the foam is formed into a closed cell shape. Is desirable.

The columnar body 1 may have a columnar shape or a certain hexagonal shape. However, since a plurality of the columnar bodies are integrated and integrated, the diameter or the outer dimension thereof is 20 to 50 mm.
Degree.

Hereinafter, a case where the pillow core material is formed by using the cylindrical shape will be described. First, a plurality of foamed resin columnar bodies 1 are cut into a suitable length as a core material of a pillow, and one of these is disposed at the center, and a plurality of orbiting columnar bodies 11, 12 are provided at the outer peripheral portion thereof and in the orbiting direction. , 13, 14, ... Are arranged in an array. In this case, on the outer peripheral surface of the central columnar body 1, the orbiting columnar bodies 11, 12, 13, ...
.. are arranged so as to be in contact with each other, and the orbiting columnar bodies 11, 12, 13, 14, ... Are fixed to each other by adhesion or another method.

Therefore, the central columnar body 1 is surrounded and held by the orbiting columnar body so as to be integrated. At this time, the orbiting columnar body has an outer dimension suitable for a pillow.

The surrounding columnar bodies 11, 12, 13, 14, ... Surrounding the central columnar body 1 along the orbiting direction are one round as shown, or the central columnar body 1, the orbiting columnar body 11 , 12 ... If the diameter is small, this orbiting columnar body is provided on the outer periphery thereof.
It is also possible to have a circling state in which 3, 24 ... Are arranged, and in this embodiment also, the circling columnar body 2 on the outer peripheral side is provided.
Circular columnar bodies 2 1, 2, 23, ... Also adjacent to each other
1, 2, 23, ... Between and around the inner circumference of the columnar body 1
.. are integrally formed by adhesion or the like. Adhesion between the columnar bodies is performed by applying an adhesive between the peripheral surfaces of the adjacent columnar bodies, or by adhering between the end faces of the arrayed columnar bodies, an aluminum foil is provided on one surface of the resin film of the same material as the columnar bodies. The vapor-deposited material is cut into the shape of the end surface of the arrayed columnar body, and this is heated and heat-welded to be integrated.

In this way, the orbiting columnar bodies 11, 12, ... Arranged adjacent to each other in the orbiting direction so as to surround the peripheral surface of the central columnar body 1 have a cross-sectional diameter as a whole. It has a hexagonal shape and other shapes. Therefore, this outer surface is inserted into a separately manufactured cover, for example, a cylindrical cover, and is wrapped with the cover. The pillow using the core material of this pillow can be freely rotated according to the purpose and site of use, and can be used freely at the abutting site according to the user's preference. To

In the case of the above construction, the outer shape of the core material of the pillow is hexagonal whether the columnar body has a circular cross section or a hexagonal shape. Alternatively, it can be used by abutting against the waist, and if it is desired to press a part of the waist and the like particularly strongly, the corner of the core material can be used so as to abut on the body.

[0014]

The pillow core material according to the present invention is easy to manufacture and convenient to use because a large number of columnar bodies made of foamed resin are rotatably in the circumferential direction and fixed to each other. There is an advantage that can be. Further, in the invention according to claim 2, since the circular or hexagonal columnar body is used, the arrangement and combination are surely secured, and not only the material as the core material but also an appropriate cushion according to the shape is provided. There is. In the invention according to claim 3, since the orbiting columnar body is arranged so as to surround the outer periphery of the central columnar body, there are advantages that the manufacturing is simple and the adjacent columnar bodies can be easily joined. is there.
