SOLUTION: In an upper surface portion U of a pillow P, a righ recessed portion 5 and a left recessed portion are formed between the central portion 1 and a left side end 3 and between the centeral portion 1 and a left side end 3. Portions between the right/left side ends 2, 3 are respectively made low in a recessed shape. A recess 4 is formed in the central portion 1. In application, a head of a person who faces just above 71 that is placed on the recess 4 of the central part 1 of the upper surface portion U in the pillow P is softly supported and stabilized, and when the person tends to face rightward to softly press the pillow P, the head 71 can be easily directed rightward to have a rightward head position 72 while having a rolling down feeling to the righ recess portion 5 and is fitted stably in the right recess 5. When the person moves the head toresume the former position, the person can takes the position again easily with less force since the pillow P is soft.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pillow. More specifically, a valley is provided between a central portion and left and right side edges on an upper surface portion of the pillow, and the pillow is laid up. The present invention relates to a pillow that is suitable as a structure of a sleep pillow or a healthy pillow that can easily and freely turn the face of the head directly above and right and left and stabilize the head.

[0002]

2. Description of the Related Art As shown in FIG. 11A, a conventional pillow has a central portion 1 of an upper surface U of a pillow P which is low and a right end 2 and a left end 3 are gently raised. As shown in FIG. 11B, the central portion 1 of the upper surface U of the pillow P is depressed in a round shape, and the right end 2 and the left end 3 are high. As shown in FIG. It is common that a hole is made in the center 1 of P in a round shape. In these prior arts, as shown in FIG. 12, when the head 71 is placed directly on the central portion 1 of the upper surface portion U of the pillow P, the central portion 1 is lowered and the right end 2 and the left end 3 are raised. , The pillow is shaped so that the directly upward head 71 does not move.

[0003]

When sleeping, humans frequently move their bodies rather than staying in the same posture for a long time. In particular, the head moves a lot to improve blood flow in the neck. However, with conventional pillows, the head position is fixed and the structure is difficult to move. Therefore, when the face of the head is turned sideways while lying on its back, as shown in FIG. 12, in the pillow P in which the depression in the center 1 is large and the right end 2 and the left end 3 are high, FIG.
As shown in FIG.
The face is turned to the right like the right-sided head 72 in (b), and the pillow P is replaced. Further, as shown in FIG. 14, in the pillow P having a small depression in the central portion 1, the head 71 has a face facing directly upward.
With the right-sided head 72 with the head turned to the right and the face turned to the right side, and similarly the left-sided head 73 with the face turned to the left side, the upper surface U of the pillow P is climbed toward the left and right end portions. Thus, the trajectory L of the head center O draws a downward arc where the right lateral head 72 and the left lateral head 73 are high, and the overhead head 71 is low. Therefore,
The head is most stable when the head is directly upward 71
The left lateral head 73 is unstable and tries to roll toward the central part 1. For this reason, a force is required on the neck and shoulders in order to turn sideways, and a holding force is required on the neck and shoulders in order to maintain the sideways state.

[0004] As described above, even when the conventional pillow is lying on the back, it is impossible to place the face in a horizontal position, and a burden is applied to the neck and shoulders. In addition, due to this burden, the movement of the head and neck is restricted, resulting in insufficient blood circulation, and many people suffer from difficulty in sleeping well and suffering from headache, neck and shoulder stiffness, and the like. An object of the present invention is to provide a pillow that eliminates these drawbacks and enables a good night's sleep and a comfortable wake-up.

[0005]

Means for Solving the Problems A pillow that allows the face to be easily turned in the lateral direction easily while sleeping, and does not place a burden on the neck and shoulders, etc. When sleeping, the muscles and muscles of the neck and shoulders are constant. It is necessary to be able to move freely in the range from right to right and left and right together with the head, instead of the posture, and to easily hold the position when the movement is stopped.

In order to achieve the above object and to achieve the object, a pillow according to the first aspect of the present invention comprises a right valley between a center portion and a right end portion of an upper surface portion on which a head is placed, and a center portion and a left side. A left valley was provided between the ends, a valley-like low shape was formed between the center and the left and right side ends, and a dent was provided at the center to support the head lightly. In addition, what made the center part arc-shaped and flat is also included. Further, the right valley and the left valley may be inclined toward the neck or the head.

[0007]

In general, when a person is lying on his back and turning sideways, he rolls his head and turns his face sideways. Therefore, if there is a low dent in the valley between the central part of the upper surface of the pillow and the left and right side edges, when the face is turned sideways, a force acts on the head to roll down into the valley. By this action, the head inevitably rolls, and the face can be turned easily and effortlessly. When the face is turned sideways, the head becomes stuck in the depression in the valley, and the depression supports and stabilizes the head. Also, when the face is turned back, the head has a large diameter and the pillow is soft, so that the head can be rolled lightly and returned without difficulty. In addition, the provision of the recess in the center stabilizes the head even when the face is directed directly upward.

[0008] As described above, according to the pillow of the present invention in which the valleys are provided between the central portion of the upper surface of the pillow and the left and right side edges, and the recess is provided in the central portion, the head can be easily and laterally moved. It has the effect of being able to sleep without burden on the neck and shoulders.

[0009]
