Next, when air is injected into the inside from an air injecting port 6 of a jaw rest unit 5, it is inflated, so that a plug unit 6A is fitted to the air injecting port 6. Both the stopper units 3, 3 are pulled apart in a direction with their opposed surfaces 3A, 3A distant and externally fitted to a neck 7, after being pulled toward the front, when the base unit 2 comes into close contact with an upper breast part 8, a jaw 9 can be stably placed on a jaw rest part 5A. While the height of the jaw rest unit 5 is maximum when its inside is full with air, so that its amount is decreased adjusting the height when it is desired to be decreased.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a chin pillow, and more particularly to a chin pillow for correcting jaw position to maintain sound sleep.

[Conventional technology]

The human head is supported by the neck, and the neck refers to the thin part sandwiched between the head and the chest. If you look at the structure of the neck in a schematic diagram, you will see the back muscles proper at the rear of the vertebrae, the trapezius muscle 9 on both sides, the scalene muscles, and the sternocleidomastoid muscle on the front and lateral sides.

The head is normally supported by the vertebrae and various muscles, such as the inferior canal muscle and the platysma muscle.

There is cricoid cartilage at the front of the vertebrae that protects the esophagus and trachea, and on the left and right sides of the esophagus are the common carotid artery, internal jugular vein, vagus nerve,
Sympathetic nerve trunks are arranged symmetrically.

In addition, there are accessory nerves that control muscle movements, hypoglossal nerves that control the old canal muscles, and cervical nerves that control the neck muscles.

A person who sleeps while sitting in a chair on a train, etc., rocks his or her head back and forth and from side to side.In this state, the head is not in a restful state of sleep.When the head droops forward, the muscle groups mentioned above are compressed in the front.
Tension is generated in the rear, and this stimulus is transmitted to the cerebral cortex, which issues a command to restore the normal position and lift the head that had drooped forward.

During this repetition, the brain continues to be excited, making it impossible to sleep soundly.

When we sleep, we use pillows to keep our heads in the normal position when we are standing and to get a good night's sleep. Therefore, there is a saying that you should sleep with a pillow that is too high, but if you use a pillow that is too high, you will not be able to get a good night's sleep.

Sleep is a combination of physical sleep and cerebral sleep that results in restful sleep, so the key points to leading to restful sleep are (a) eliminating stimuli from inside and outside the body as much as possible, and (b) relaxing the body. It is necessary to eliminate the excitement that comes from the muscles and inner ear to the base of the cerebrum.

External stimuli include noise, light, vibrations, pressure, and temperature. Internal stimuli include the urge to defecate, which is caused by accumulation of defecation that stimulates the nerves. This is a state in which the active muscles are contracting.

Regarding (b), muscles are relaxed by lying down and resting your mind. This muscle relaxation allows the nerves that tighten the muscles to rest, and the stimulation to the cerebrum from the muscles and muscles disappears.

[Problems to be Solved by the Invention] As mentioned above, relaxing muscles is an important point in seeking a sound sleep.

However, when sleeping with a pillow, even if the pillow is at the same height, depending on the position of the head, the chin is placed too close to the chest, and as a result, the old canal presses on the cricoid cartilage, causing the inferior canal muscle group to deteriorate.

Pressure on the platysma muscles, etc., excites surrounding nerves and stimulates the cerebrum, preventing deep sleep. In particular, as mentioned above, the anterior cervical region is home to vital organs such as the trachea, vagus nerve, sympathetic nerves, common carotid artery, and internal jugular vein.
They are sensitive to pressure from the outside and react sensitively to even small abnormalities, which stimulates the cerebrum and interferes with restful sleep. However, no means for preventing such forward tilting of the neck while sleeping has yet been disclosed.

On the other hand, if you sleep on your side, it is possible to get a good night's sleep by changing your pillow, but in modern society, traveling by means of transportation has become an important part of social life, and chairs on airplanes and Shinkansen trains are becoming more and more important. Sleeping while sitting has also come to have an important meaning.

However, when sleeping in a chair, the main muscles that support the head, such as the intrinsic dorsal muscles, trapezius muscles, and scalene muscles, also relax, so the head tilts forward and to the left and right.

This tilting stimulates the muscles and causes excitement in the cerebrum,
Posture is corrected. As a result of this repetition, the muscles are continuously stimulated, which means that it is impossible to sleep soundly.

Stress also has a strong effect on the front of the body, especially the internal organs, pectoral muscles, thymus gland, old ducts, and tongue muscles, so those who are under stress will tense and contract more than necessary in these areas, causing the neck muscles to contract. It is necessary to stretch and hold it in the normal position.

In view of the above-mentioned circumstances, the present invention provides a chin pillow that corrects the position of the jaw and eliminates insomnia caused by stress, and that can maintain a sound sleep even for a short time while sitting on a chair in public transportation. It was developed for the purpose of

[Means to solve the problem]

As a means to solve the above-mentioned problems, this invention provides a locking body that comes into contact with the rear part of the jaw at the rear of the base that comes into contact with the maxillary thorax near the chin, and a chin rest that has a height adjustment means on the front upper part of the base. We took a technical measure called a chin pillow, which is characterized by

[Effect]

The present invention configured as described above has the following effects.

When the base body is brought into contact with the upper chest area near the chin and the locking body provided at the rear part is brought into contact with the rear part of the neck, the base body is stabilized on the upper chest area near the chin without falling.

In this state, the jaw rest disposed on the front upper part of the base body is located directly below the jaw, so the height is adjusted until the upper end surface of the jaw rest comes into contact with the jaw.

As a result, even if you try to tilt your head forward, your chin is supported by the chin rest, so your head will not tilt forward, meaning that even if you sleep using this while sitting on a chair, your head will remain in a normal posture. This prevents the so-called rattling motion of shaking your head, allowing you to sleep soundly even for a short period of time.

It can also help relieve tension in the front of your neck caused by stress, allowing you to sleep more soundly.

〔Example〕

Embodiments of the invention will be described based on the drawings.

Fig. 1 is a side view showing the state in which the chin pillow of the first embodiment is used, Fig. 2 is a plan view, Fig. 3 is a front view, and Fig. 4 is a sectional view taken along the line A-A in Fig. 2. .

In the figure, the chin pillow 1 is a child circuit U made of soft synthetic resin material.
A hollow substantially C-shaped locking body 3 is provided at the rear of the hollow base body 2.
3 are formed symmetrically, and the base body 2 and the locking bodies 3, 3 are formed into an integral hollow body with hollow cavities communicating with each other.

An air inlet 4 is formed in the base body 2, and a stopper 4A is fitted into the air inlet 4. Therefore, when air is injected from the air inlet 4, the base body 2 and the locking bodies 3, 3 become a substantially annular hollow body with a flat surface and a partial notch, as shown in FIG. It has strength.

Therefore, the true identity of both images 3.3 is the opposing surface 3 at its tip.
The size is such that both images 3, 3 can be fitted around the neck 7 by separating A, 3A away from each other.

A hollow jaw rest 5 made of a soft synthetic resin material is formed at the front upper part of the base body 2. The jaw rest 5 has a substantially trapezoidal shape with a height that allows it to stand upright and support the jaw 9 when the locking bodies 3, 3 are hung on the neck 7 and the base 2 is in contact with the upper chest 8. A chin rest part 5A consisting of a half-moon-shaped recess at the upper end and a slightly high circumferential pressure 5B are formed from both sides of the chin rest part 5^ to the front part.

Further, an air inlet 6 is opened at the lower front portion of the jaw rest 5, and a plug 6^ is fitted into the air inlet 6.

According to this invention configured as described above, first, when air is injected into the interior from the air inlet 4 of the base body 2, the base body 2 and the locking bodies 3, 3 expand to a certain degree of hardness and elasticity. Therefore, the plug body 4^ is fitted into the air inlet 4.

Next, when air is injected into the jaw rest 5 through the air inlet 6, the jaw rest 5 expands, and the plug 6A is fitted into the air inlet 6.

Thereafter, as shown in FIG. 2, the two image bodies 3.3 are pulled apart with their opposing surfaces 3A and 3^ in the direction away from each other, fitted onto the neck 7, and pulled forward, and then the base body 2 is placed on the upper chest. 8, the jaw 9 can be rested on the jaw rest part 5^ as shown in FIG. Furthermore, the height of the jaw rest 5 is highest when it is filled with air, so if it is desired to be lower, the height can be adjusted by reducing the amount of air.

In this way, this invention can easily prevent the jaw from tilting forward by stopping and supporting it, so it can be used to relieve tension in the neck caused by stress and get a good night's sleep. Moreover, even if you fall asleep while sitting in a chair, you can sleep soundly.

In addition, since it is hollow, there is no risk of harm to the human body, and once the air is removed, the volume becomes small, making it easy to take with you when traveling.

Note that this embodiment can be modified as shown in FIGS. 5 and 6 as a second embodiment.

FIG. 5 shows a side view, and a dividing wall 5C dividing the height into two is provided in the jaw rest 5, and two air inlets 6.6 are also formed on the upper and lower sides. - According to this configuration, the height of the jaw rest 5 can be adjusted by adjusting the amount of air above the partition wall 5C.

FIG. 6 shows a plan view, and auxiliary parts 3B, 3B are formed as hollow bodies on the surfaces of the locking bodies 3, 3 facing the ribs 7, and the auxiliary parts 3B are formed as hollow bodies.
An air inlet 3C with a stopper 30 was formed in each of B and 3B.

By injecting air into the auxiliary portions 38, 38 and increasing or decreasing the amount of air, the distance of the jaw rest 5 relative to the neck 7 can be adjusted.

In this third embodiment, base #2 is a disc-shaped plastic molded member, and is integrally formed with a rubber sponge material 2A attached to the lower part. A bearing portion 28.2B is formed at the center of the upper surface of the base body 2, and a height adjusting means 10.11 is rotatably attached to the bearing portions 2B, 2B via a shaft 12.

The height adjustment means 10.11 consists of a support 10 and a threaded shaft 11, and the support 10 stands vertically with its lower part pivoted to the bearings 2B, 2B, and its upper end extends downward. A screw hole 10^ is formed.

The screw shaft 11 has a male thread carved on the outer surface of an elongated cylindrical body, the lower part is screwed into the screw hole 10A of the support, and the upper end is fixed to the receiving plate 5D at the lower part of the jaw rest 5.

The chin rest 5 has a rubber cushion 5 attached to the upper surface of a receiving plate 5D made of plastic, and a half-moon-shaped chin rest 5A is recessed on the upper surface of the cushion 5F. A slightly higher circumferential pressure 5B is formed laterally.

The shaft 12 is made of metal, has a distal end that extends long toward the rear of the base body 2, and has a curved distal end edge to which the locking body 3 is integrally formed. A neck rest 3C made of a rubber material is formed on the surface of the locking body 3 facing the neck 7.

According to this embodiment having the above configuration, the height of the jaw rest 5 can be adjusted by rotating the screw shaft 11, so that the neck rest 3C of the locking body 3 is placed on the neck 7 of the base 2. is brought into contact with the upper chest 8, the chin rest 5 is rotated to adjust the height, and the chin 9 can be placed on the chin rest 5^. This effect is similar to that of the first embodiment.

In addition, in this invention, the design of the tip of the locking body can be changed so that it comes into contact with the back from the scraps.

Further, the locking body shown in FIG. 8 can be separated from the shaft, and its base end can be inserted into a fixing hole (not shown) provided in the base body and fixed with a screw.
