Abstract

<P>PROBLEM TO BE SOLVED: To provide a pillow, decreasing traction force in the neck muscles in a sleep to promote muscular relaxation to stimulate blood circulation and improve metabolism, thereby allowing a user to obtain an agreeable sleep and holding an agreeable angle of the neck when he/she has a pain in the neck. <P>SOLUTION: This circular pillow is provided with an elastic flat part in the central area, and an elastic core body disposed in the periphery thereof at a height. At the time of lying on his back, the back of the head fits into the central recessed part to support the temporal part on the peripheral elastic core body, whereby the head is held at the lower position so that the traction force in the muscles at the front and the rear of the neck is decreased to promote muscular relaxation. In lying on the side, the temporal part is supported at a suitable height by the peripheral elastic core body to decrease the traction force in the muscles of the side of the neck and promote relaxation. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

Detailed Description of the Invention

The present invention relates to a pillow that promotes muscular relaxation of the neck during sleep, reduces neck pain or stiff shoulders, and can sleep comfortably.

Technical background

A variety of pillows have been developed to provide comfortable sleep and promote health, and various types of pillows have been developed. However, there is a great demand for more comfortable pillows.

There are pillows having square and concave holding elements as seen in JP-A-10-43022, JP-A-11-244113, JP-A-2001-104126, and the like.

When sleeping with a high pillow in the supine position, the neck is bent forward and the posterior bay deformation of the lower cervical vertebra is promoted, and trapezius, plate muscle, rhomboid, etc. It continues to add traction to the muscle county, creating muscle tension and creating causes such as stiff shoulders and neck stiffness. In addition, in the case of a user with cervical pain, extension of the cervical muscle due to cervical forward bending causes great pain.

In addition, when sleeping, the pillow is displaced and the pillow is displaced, or when the pillow is in a lateral position, a low pillow or a square pillow with a concave central part causes the neck to bend laterally, causing the sternocleidomastoid muscle, shoulder blade Continued to apply traction force to the cervical side muscle group, such as the levator muscles, creating muscle tension, leading to misbehavior.

The present invention solves such a problem, and its purpose is to hold the head low in the supine position, to have a moderately high height in the lateral position, and for a user with neck pain. It is an object of the present invention to provide a pillow that can fix and hold the head during sleep and can obtain a comfortable sleep and health promotion.

In order to solve the above-mentioned problems, the pillow according to claim 1 and claim 2 has a circular recess so that the head can be held low in the supine position, and a circular convex portion in the periphery when the supine position is maintained. It is possible to hold the head at an appropriate height.

Even when the angle of the pillow changes due to turning over or the like, the head holding state does not change because of the circular shape.

The pillow according to the present invention has a circular shape, and has a variety in the direction in which the head is applied, and has a wide range of response to movement such as turning over during sleep.

The pillow of the present invention can hold the head low in the supine position, the traction force to the muscle group on the back of the neck does not work, and the muscle relaxes, and the head with the surrounding convex part is used to cause neck pain. Even a person can maintain a favorite angle, so a good sleep is possible.

In addition, by supporting the head with the surrounding convex portions in the lateral position, the pulling force to the muscle group on the side surface of the neck does not work and the muscles relax and can sleep.

If the relaxed state of the cervical muscles can be maintained, blood circulation is improved, metabolism is improved, and shoulder stiffness and the like can be improved.

Hereinafter, embodiments of the pillow of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing an example of a form of a pillow according to claim 1 of the present invention. FIG. 2 is a sectional view thereof. A cylindrical core body 11 is provided around a circular flat central portion 10.

The central flat portion 10 has a thickness of about 0 to 30 mm and a size of about 120 mm in diameter, and the surrounding core body 11 has a shape of a donut shape surrounding the central flat portion with a diameter of about 80 mm.

The central flat portion 10 and the peripheral core body 11 are filled with different types of elastic bodies shown in claim 3 or the same elastic bodies. However, since the shape of the peripheral core 11 is required to be maintained, a bag-like partition is provided when the internal elastic body is a shell, a granular solid, or the like (FIG. 5). However, the shape maintaining method is not limited to this. Absent. Moreover, when taking the form shown in Claim 4 and Claim 5, it is filled with air.

FIG. 6 shows the user's head in the supine position, the back of the head is contained in a concave depression, and the side of the head is supported by the surrounding core 11, and the head position is in contact with the central flat part 10 or in a floating state. Hold the head in a low position.

FIG. 7 shows the user's head in the lateral position, and the head is held at an appropriate height by the peripheral core 11.

FIG. 3 is a perspective view showing an example of the form of the pillow according to claim 2 of the present invention. FIG. 4 is a sectional view thereof. A cylindrical core or an elliptic cylindrical core having a diameter of about 80 mm is formed into a donut shape.

The internal elastic body is filled with the elastic body shown in claim 3. However, when the shape of the internal elastic body is a shell, a solid solid or the like and it is necessary to maintain the shape, a bag-like partition is provided (FIG. 5), but the method of maintaining the shape is not limited to this. Moreover, when taking the form shown in Claim 4 and Claim 5, it is filled with air.

It is an external appearance perspective view which shows the whole pillow of Claim 1 which concerns on the form of this invention. It is a cross-sectional view of the pillow of FIG. It is an external appearance perspective view which shows the whole pillow of Claim 2 which concerns on the form of this invention. It is a cross-sectional view of the pillow of FIG. It is the internal perspective view which showed the partition which divides the filling material of a peripheral core. It is a figure which shows the state which the user put the head on the pillow of FIG. 1 from a parietal direction. It is a figure which shows the state which the user put the head on the pillow of FIG. 1 from a side surface direction. It is a figure which shows the state which the user put the head on the pillow of FIG.
