FIG. 4 is a sectional view taken along line CC shown in FIG. The pillow 1 has generally fan-shaped left and right sides 11 and 12, rectangular lower and back sides 13 and 14, an arched upper surface 15, and a generally sector-shaped cross-section. The pillow 1 is placed on the curved portion of the upper surface 15 with the head and a part of the body placed thereon, and the corners of the lower surface 13 and the back surface 14 are connected to each other. It is a form that can swing back and forth, and various stretches described later (for example, see supine pose 1) can be performed. In this embodiment, the angle formed by the lower surface 13 and the rear surface 14 (the central angle α of the portion corresponding to the core of the fan) is about 120°, but the angle is not limited to 90° or more and 170° or less.

The pillow 1 contains a pillow body 2 composed of a plurality of foamed resin members, a plurality of (two in this embodiment) spheres 3 fitted inside the pillow body 2, and the pillow body 2 and the spheres 3. and a cover 4 for The pillow 1 has a substantially fan-shaped cross section by forming a semicircular upper surface side and a triangular lower surface side in a side sectional view. The pillow main body 2 includes a pair of end forming units 21a and 21b arranged at both left and right ends of the pillow main body 2, an intermediate forming unit 22 arranged between the pair of end forming units 21a and 21b, and , a pair of end forming units 21 a and 21 b and a forming sheet 23 wound around the intermediate forming unit 22 . The cover 4 is provided with a fastener 5 as an opening/closing means, and the pillow body 2 and the sphere 3 can be accommodated therein. The molded sheet 23 is a rectangular sheet with a thickness of about 1 cm. By winding this sheet, the unit is well organized and the cushioning property is enhanced. Note that the thickness of the molded sheet is not limited to this, and other thicknesses may be used.

Both of the end molding units 21a and 21b are molded from a material harder than that of the intermediate molding unit 22. As shown in FIG. The end molding units 21a and 21b are made of high-resilience chip urethane foam, the middle-part molding unit 22 is made of soft urethane foam, and the molding sheet 23 is made of low-resilience urethane foam. The hardness of the end forming unit 21 is preferably 50 Newton (hereinafter "N") or more and 360N or less. The hardness of the intermediate part molding unit 22 is preferably 10N or more and 100N or less. The hardness of the molded sheet 23 is preferably 10N or more and 75N or less. The foamed resin member is preferably open-cell foam, and more preferably urethane foam, but is not limited to this. The end molding units 21a and 21b are not limited to chip urethane foam, but may be semi-rigid urethane foam.

Each of the end molding units 21a and 21b is composed of a curved-side molded body 211 that is semicircular in cross-sectional side view, and a triangular base-side molded body 212 that is assembled to the bottom side of the curved-side molded body 211. be done. Similarly, the intermediate part molding unit 22 is composed of a curved side molded body 221 which is semicircular in cross section, and a triangular base side molded body 222 which is assembled to the bottom side of the curved side molded body 221. be. In this way, each of the end forming units 21a, 21b and the intermediate forming unit 22 accommodates the bending-side formed bodies 211, 221 and the base-side formed bodies 212, 222 inside the cover 4 to form a generally sectoral shape in a side view. However, it is not limited to this, and for example, a molded body having a substantially fan-shaped cross section may be integrally formed. This embodiment is preferred for neck pillows and has a width dimension of about 40 cm and a height of about 10 cm, but is not so limited.

The sphere 3 is made of a material different from the foamed resin member, and for example, a rubber ball made of elastomer resin can be used. Other urethane materials or cork may be used as long as they are made of a hard material. The sphere 3 may be oval. In this embodiment, since the sphere 3 is fitted inside the pillow body 2, the curved side molded body 221 is formed with a hemispherical depression into which the upper part of the sphere 3 is fitted, and the base side molded body 222 is formed with a sphere. A hemispherical depression is formed into which the lower part of 3 is fitted. The spheres 3 are arranged symmetrically from the center of the pillow body 2 toward both left and right ends, and the pair of spheres 3 closest to the center is preferably positioned 3 to 9 cm from the center.

When sleeping, the lower surface 13 or the back surface 14 is placed on the ground side, and the head or waist is placed on the curved upper surface 15 for use. The middle molding unit 22 arranged in the middle part of the pillow 1 is made of a softer material than the end molding units 21a and 21b, so that when lying on one's back, the head or waist (torso) of this embodiment can be adjusted. By applying it, the head and torso can easily sink into the pillow 1, and in the sideways state, by placing the head and flanks on the end forming units 21a and 21b, the sinking of the head and torso can be suppressed. be. Because of this effect, for example, the middle part molding unit 22 is formed of a flexible material that has an appropriate amount of sinking that does not put a burden on the neck and waist when lying on one's back. By molding the pillow to a height that does not put a burden on the neck, it can be used as a pillow that does not put a burden on the neck and hardly causes ptosis of internal organs. In addition, in the supine state, the body weight can be distributed and supported, and specific parts are less likely to be injured. The spheres 3 embedded in the intermediate molding unit 22 can optionally be used as means for pressing specific muscles or meridians. According to the present embodiment, even when used during sleep, it is possible to obtain good quality sleep without imposing an excessive burden on the body. Can practice membrane release, body weight training, etc.
