Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In the following drawings, the same or corresponding parts are designated by the same reference numerals, and the description thereof will not be repeated.
In this specification, the front side means the side of the pillow on which the head or neck rests, and the top, bottom, left, and right sides mean the top, bottom, left, and right directions, respectively, when facing the front side of the pillow.

Figure 1 shows a pillow 1 of the present invention. Figure 1A shows the pillow 1 with the elastic sheet member 20 attached. Figure 1B shows the pillow 1 with the elastic sheet member 20 removed. With reference to Figures 1A and 1B, the pillow 1 has an elastic sheet member 20 stretched over the front surface of the headrest body 10. The elastic sheet member 20 is a sheet made of an elastomer resin, such as an elastic synthetic resin sheet of polystyrene-based elastomer, acrylic-based elastomer, silicone rubber, or the like. The elastic sheet member 20 is not particularly limited as long as it is made of a material that has the elasticity and strength appropriate for the application, and a net or mesh can also be used.

The headrest body 10 has multiple protrusions 11 on the left and right side surfaces. The protrusions 11 are protrusions provided on the side surfaces of the headrest body 10. The elastic sheet member 20 is held to the headrest body 10 by hooking the retaining portions 21, which are holes provided at the ends of the elastic sheet member 20, onto the protrusions 11.

The headrest body 10 has protrusions 12, 13 extending in the up-down direction at both the left and right ends of the front surface. A curved surface 14 is provided between the protrusions 12, 13, and is set back from the protrusions 12, 13, connecting the protrusions 12, 13. Because the curved surface 14 is set back from the protrusions 12, 13, when the elastic sheet member 20 is tensioned, the elastic sheet member 20 is separated from the curved surface 14.

Figure 2A shows the front of the headrest body 10, and Figure 2B shows the rear of the headrest body 10. In the embodiment of Figure 2, the vertical width of the curved surface 14 of the headrest body 10 is narrower than the vertical width of the protrusions 12, 13. This configuration has the advantage that the overall volume of the pillow is small, lighter, and stronger. In addition to the embodiment of Figure 2, the headrest body 10 can also be configured in other ways, such as making the vertical widths of the curved surface 14 and the protrusions 12, 13 almost the same or the same.

The curved surface 14 is formed so that the lower width _W2 is wider than the upper width _W1 . By making the lower width _W2 wider than the upper width _W1 , the weight is distributed when the head and neck are placed on the pillow, and the pillow allows the user to maintain a relaxed posture without strain.

The headrest body 10 has four protrusions 11 on each of the left and right sides. The cross-sectional area of the protrusions 11 increases from the front to the rear of the pillow 1. The rear end surface 11a of the protrusions 11 is a semi-elliptical surface that is approximately parallel to the front surface of the pillow 10 so that the elastic sheet member 20 can be easily hooked and held. There is no particular limit to the number of protrusions as long as the effects of the present invention can be obtained, and there can be about 2 to 10 protrusions on each of the left and right sides.

The headrest body 10 has a fixing member attachment portion 15 extending in the left-right direction between the protrusions 12, 13. The fixing member attachment portion 15 is a cylindrical shaft member extending in the left-right direction. A fixing member 30 (Figure 5) can be attached to the fixing member attachment portion 15, and the attached fixing member 30 can rotate around the axis of the fixing member attachment portion 15.

When considering use in bathrooms and outdoors, the headrest body 10 is preferably a hollow resin molded body. For example, it is preferably a blow molded body made of polyethylene resin, polypropylene resin, ABS resin, or the like. The advantage of using a blow molded body is that it floats on water, is lightweight, and has the necessary strength.

Figure 3 shows the side of the headrest body 10. The headrest body 10 is formed in a bow shape with the center protruding toward the front and the upper and lower parts recessed from the center. This shape ensures that the back of the head and neck are securely supported, resulting in a pillow with excellent relaxation effects.

Figure 4 shows the elastic sheet member 20. The elastic sheet member 20 is a sheet made of elastic resin that is integrally formed as a whole. Four holding parts 21 for hooking onto the headrest body 10 are formed on each of the left and right ends of the elastic sheet member 20. The space between adjacent holding parts 21 is formed in an approximately arc shape. The holding parts 21 are semicircular holes formed in the sheet. The periphery 23 of the holding part 21 is molded to be thicker than the sheet part in the center of the elastic sheet member 20. Furthermore, the claw part 24 on the outer edge side of the holding part 21 is molded to be the thickest at the part that contacts the holding part 21, and is even thicker than the periphery 23. The thickness of the claw part 24 is made thinner toward the tip. This shape makes it easy to hook onto the protruding part 11 of the headrest body 10, and is less likely to break and can withstand long-term use.

The thickness of the elastic sheet member 20 can be selected according to the material and the desired strength, and is not particularly limited, but for example, it can be about 0.5 to 5 mm when not stretched (when not attached to the headrest body), and preferably about 0.5 to 3 mm. In addition, by forming the edges of the sheet to be thick, it is possible to ensure strength even with a thin sheet, and make the sheet less likely to break.

The hardness of the elastic sheet member 20 is not particularly limited, but for example, the durometer hardness (JIS K 6253) can be about 30 to 60, and 30 to 50 is more preferable. From the viewpoint of excellent rubber elasticity and high tensile strength, for example, the material of the elastic sheet member can be a thermoplastic elastomer compound such as Arneston (registered trademark, manufactured by Kuraray Co., Ltd.). The elastic sheet member 20 can be obtained, for example, by injection molding or extrusion molding.

Figure 5 shows the fixing member 30. The fixing member 30 has an opening, cylindrical fitting portion 31 so that it can be rotatably fitted into the fixing member mounting portion 15 of the pillow 10, and a suction cup mounting portion 32 provided on the mounting surface extending from the fitting portion 31. The suction cup mounting portion 32 has a hole 33 formed therein for mounting a suction cup. In the example of Figure 5, the holes 33 are formed in two parallel locations, but the arrangement and number of holes are not particularly limited as long as the effects of the present invention can be obtained. For example, one hole may be provided in the center so that the pillow 1 is supported by one suction cup, or three or more holes may be provided.

Figure 6 shows the state in which the fixing member 30 is attached to the pillow 1. Two suction cups 34 are attached to the fixing member 30. The fixing member 30 is rotatable with respect to the fixing member attachment portion 15 of the headrest body 10. This allows the pillow 1 to be used at any angle.

For example, referring to FIG. 7, in the case of a deep Japanese-style bathtub, suction cups 34 may be attached to the flat portion of the outer edge of the bathtub, and pillow 1 may be positioned at the corner of the bathtub. Also, referring to FIG. 8, in the case of a shallow and long Western-style bathtub, suction cups 34 may be attached to the upper part of the inner surface of the bathtub, and pillow 1 may be positioned inside the bathtub. Also, referring to FIG. 9, in the case of a bench-type bathtub with a step inside the bathtub, suction cups 34 may be attached to the outer wall of the bathtub to secure pillow 1.

When using the pillow 1 as a bathtub pillow, the fixing member 30 is attached as described above, and the suction cups 34 are attached to the wall or bathtub to fix the pillow. On the other hand, when using the pillow 1 outdoors, the fixing member 30 can be removed. When the fixing member 30 is removed, the fixing member attachment part 15 can be used as a handle for convenient transportation.

The pillow of the present invention can be particularly advantageously used as a bathtub pillow, an outdoor pillow, etc.
