DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pillow that allows a user to sleep comfortably by placing the user in a natural sleeping position with less burden.

[0002]

2. Description of the Related Art Conventionally, there has been a demand for a pillow that allows a user to sleep comfortably by placing the user in a sleeping position with a small burden. However, when sleeping with conventional pillows, the user's neck (cervical vertebra) becomes unnatural and strains the user's body, making it difficult for the user to sleep comfortably and the neck and shoulders. It was a stiff cause. In particular, while sleeping, the user unconsciously rolls over, but with a conventional pillow, when the user turns to the side, the position of the neck is higher than when the user is facing the back by the shoulder width, and the cervical spine is The neck was in a curved state and the strain was on the neck. In addition, the height or hardness of the pillow suitable for the user to sleep comfortably varies depending on the user's physique, head shape or taste and physical condition, but conventional pillows take such points into consideration. Did not.

[0003] Accordingly, an object of the present invention is to provide a pillow that allows a user to sleep comfortably by placing the user in a natural sleeping position with less burden.

[0004]

SUMMARY OF THE INVENTION The present invention comprises a pillow body which is formed of an elastic body and whose upper surface is formed by a concave curved surface portion and a pair of convex curved surface portions sandwiching the concave curved surface portion. The central part of the user is placed on the concave curved surface part, and the tip of the user's neck and the user's head is placed on each of the pair of convex curved surface parts for use. The above object has been achieved by providing a pillow, wherein the height of the convex curved surface portion is higher than the height of the other convex curved surface portion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A pillow according to the present invention will be described in detail with respect to a first embodiment with reference to the drawings.

As shown in FIG. 1A, the pillow 10 of the first embodiment is made of an elastic material and has an upper surface formed with a concave curved surface portion 11 and a pair of convex curved surface portions 12a and 12b sandwiching the concave curved surface portion 11. With the pillow body 1 formed, the central part of the head P1 of the user P is placed on the concave curved surface part 11, and the neck part P2 of the user P and the tip of the head P1 of the user P are A pair of convex curved surface portions 1
2b and 12a, and the height H1 of the one convex curved surface portion 12a is higher than the height H2 of the other convex curved surface portion 12b (H1>). H2).

The pillow according to the present invention may have a structure in which an elastic plate is disposed on the upper surface or the lower surface of the pillow main body, in addition to the case where the pillow is configured as a single body as in the first embodiment. For example, the pillow 10 of the present invention has a configuration in which a relatively thin elastic plate 2a is arranged on the lower surface of the pillow main body 1 as shown in FIG. 2A, as shown in FIG. A configuration in which a relatively thick elastic plate 2b is arranged on the lower surface of the pillow body 1, as shown in FIG. 2C, a relatively thin elastic plate 2a and a relatively thin elastic plate 2b are formed on the lower surface of the pillow body 1. A configuration in which a relatively thick elastic plate 2b is disposed, or a configuration in which a relatively thin elastic plate 2a is disposed on the upper surface of the pillow main body 1 as shown in FIG.

The pillow of the present invention can have a structure in which an elastic plate is appropriately disposed on the upper surface or the lower surface of the pillow body as illustrated in FIGS. 2 (a) to 2 (d). The height and hardness of the (pillow body and elastic plate) can be changed as appropriate. In addition, the pillow of the present invention may have a configuration in which the pillow body and the elastic plate are housed in a pillow cover.

The pillow 10 according to the first embodiment described above is similar to the pillow of FIG.
As in the first usage pattern shown in (a), the tip of the head P1 of the user P is placed on the higher convex curved surface portion 12a and the lower convex convex surface portion 12b is placed on the lower convex convex surface portion 12b. The user's neck P2 can be placed and used. In the pillow according to the first embodiment, the tip of the head P1 of the user P is placed on the lower convex curved surface portion 12b as in the second usage pattern shown in FIG. 1B. The user's neck P2 can be placed on the higher convex curved surface portion 12a and used.

As described above, according to the pillow of the present invention, the central portion of the head P1 of the user P is held by the concave curved surface portion 11, and the neck P2 of the user P and the head P1 of the user P Are held by the convex curved surface portions 12a and 12b. Therefore, the user can be put into a natural sleeping posture with a small burden, and can sleep comfortably. Also, when the user turns sideways,
The neck is not strained without the cervical spine becoming curved. Furthermore, the height or hardness of the pillow suitable for comfortable sleeping can be adjusted according to the user's physique, head shape, taste, or physical condition.

[0011] In the pillow of the present invention, it is preferable that the hardness of one convex curved portion is higher than the hardness of the other convex curved portion. In addition, it is preferable that at least the upper surface of the pillow body is formed of a material that becomes flexible when heated by the body temperature of the user. According to the pillow configured in this way,
The surface of the pillow body becomes more flexible so that the surface of the pillow sticks to the user according to the body temperature of the user, and absorbs and disperses the pressure applied to the user, thereby reducing the feeling of pressure that causes blood circulation.

[0012] The pillow of the present invention can select an arrangement in which the user can sleep most comfortably, regardless of the gender of women or men or the difference in physique such as the width of the shoulders. The height and hardness can be changed accordingly.

In the pillow of the present invention, "the center part of the user's head is placed on the concave curved surface part (of the pillow main body)" means that the center of the user's head is placed on the concave curved surface part of the pillow main body. In addition to the case where the portion is directly placed (see FIG. 1), the case where the portion is placed via an elastic plate [see FIG. 2 (d)] or the case where it is placed via a pillow cover (not shown) is included. The same applies to "place the user's neck and the tip of the user's head on each of the pair of convexly curved surfaces". Further, it is more preferable that the elastic body constituting the pillow body and the elastic plate has a slow elasticity.

[0014]

According to the pillow of the present invention, the user can be put into a natural sleeping position with little burden, and can sleep comfortably.
