Abstract

PROBLEM TO BE SOLVED: To continuously and effectively prevent snores while sleeping and to have a healthy sleep while preventing the snores. SOLUTION: At the time of mounting the head on the center of this pillow, a head part dividing part 2 expanded upwards in a curve shape naturally tilts the head to the left or right and a side head part is mounted on a head part mounting part 3a or 3b. At the time, since a neck part is rolled on a neck part mounting part 6a (or 6b), a sideways body posture is smoothly formed. When the sideways posture is attained, an airway is not narrowed and the frictional sound and vibration sound of a secretion inside the airway and tissues surrounding the airway are not generated even when breathing by the mouth is performed. Since the neck part mounting parts 6a and 6b of different heights are respectively successively connected at the front and back in a vertical direction of the head part mounting area part, by sleeping while positioning the neck part so as to mount it on a more suitable neck part mounting part 6a or 6b corresponding to the shapes of the neck part and head part of a user, a more comfortable sleep effect is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pillow, and more particularly to an improvement in a pillow that prevents snoring and induces a good night's sleep.

[0002]

2. Description of the Related Art Conventionally, as a pillow used at bedtime,
The most common one is a bag filled with buckwheat hull inside a tubular bag whose cross section has a flat oval or flat elliptical shape, but it is filled with feathers, urethane foam, etc. to give a soft feel. Things are well known. Since bed pillows are indispensable for maintaining health, a wide variety of pillows have been conventionally devised and sold. For example, it is no exaggeration to say that things that relieve stiff shoulders, neck stiffness, back pain, etc., that induce sleep, and that can be adjusted in height are flooding the world. However, it does not seem that much is intended to prevent snoring.

As one example, there is a neck shiatsu pillow described in Japanese Utility Model Laid-Open Publication No. 7-17234 (hereinafter referred to as "first conventional example"). In this first conventional example, a horizontal partition and a vertical partition are provided in the center of the pillow, and the left and right and lower center of the pillow are formed higher and the upper center is formed lower by filling the middle material. The height and height of the pillow's neck and head make it possible to acupressure the neck in the supine position and make it harder to snore.In the sideways position, the neck will not bend and you can sleep naturally. is there. As another conventional example, there is a sleep pillow for preventing snoring described in Japanese Utility Model Laid-Open Publication No. 7-20923 (hereinafter referred to as "second conventional example").

The second conventional example has a moss-like shape in which cotton is packed by an air compressor in a cylindrical bag sewn with a cotton cloth, and an arm is formed on a concave neck portion of the moss. Putting one foot on top of it and hugging it, the body will be in a lying position, so snoring will stop.

[0005]

The neck acupressure pillow according to the first prior art has a neck portion at the lower center portion of a high tubular shape extending in the lateral direction when lying on its back, and has a V-shaped cross section. It is shaped like a letter, and the head is placed on the lower center. In this state, the neck is located high and the head is located low, so that it is considered that the airway is relatively straight and the pharynx is unlikely to be narrow, so it is difficult to snore. However, to actually prevent snoring,
It does not work well. The cause of snoring is
It is said that there are various things, the first is due to physical and mental fatigue and stress, the second is when drinking alcohol or sleeping pills,
Third, due to aging of respiratory muscles, fourth, due to obesity, fifth, if there is an abnormality in the nasal cavity, oral cavity and pharynx, sixth, it may be chronic due to other causes, The cause is supposed to correspond to one of these.

In the first case, as shown in FIG.
The soft palate a and the base of the tongue b sink back, the respiratory muscles relax (loose tension) and the airway narrows, causing snoring. Breathing by mouth to relieve mental and physical fatigue Snoring to try to get a lot of oxygen. In the case of drinking the second alcohol, alcohol reduces muscle tone, in the third case, the respiratory muscles are also loosened by the aging phenomenon, and in the fourth case, obesity causes excess fat on the soft palate and pharyngeal wall due to obesity. The pharynx grows deeper, and the airways are narrow and easily obstructed, so they unconsciously try to take in a lot of oxygen and breathe greatly in their mouths, causing snoring. In the fifth and sixth cases, snoring occurs due to structural abnormalities in the pharynx and nasal cavity.

Of the above causes, in the first to fourth cases, when lying down on the back, in addition to the above factors, the tongue extending from the mouth to the pharynx becomes blocked by its weight, Snoring becomes easier. Therefore, it has been clarified that when the head or body is turned sideways, the airway is not narrowed, thereby preventing the occurrence of snoring. From such a viewpoint, considering the first conventional example, since a V-shaped groove centered on the vertical partition is formed in the vertical direction of the pillow, the head is sandwiched between the V-shaped grooves, The structure makes it easy to lie on your back, and it is difficult to prevent snoring.

On the other hand, in the case of the second conventional example, if the arm is put on the neck of the moss, and one leg is placed on top of the moss, the body will be in a recumbent position. It is thought that it is effective for suppression or prevention.
However, such an unnatural posture does not last for a long time, and when you go to sleep, your hands and feet will soon lose their strength, and you will suddenly turn to your back from your initial posture.
In addition, it is stated that snoring can be prevented even if the pillow is held by turning over to the left or right, but the probability of being able to turn over by holding the pillow is reduced when the user is lying down. Therefore, it cannot prevent continuous snoring.

The present invention has been made in view of the above-mentioned circumstances, and a first object of the present invention is to provide a pillow capable of continuously and effectively preventing snoring during sleep. The second purpose is to provide an inexpensive pillow that can achieve a healthy sleep while preventing snoring. The third purpose is to provide a neck and head shape with individual differences.
