Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem that all former massagers had an unsuitable structure and form in finding the pinpoint which is located deep in the root between the shoulder and neck and pressed particularly effectively in massaging away stiffness in the shoulder, and that in these massagers, any strong pressing may move the user's body or the massager out of position. <P>SOLUTION: The massager to relieve stiffness is structured to have a protrusion obliquely protruding toward the root of the neck of a user when he stabilizes his head with his body lying on his side. This is the best structure and form to find the pinpoint which is located in the depth of the root of the shoulders and neck and pressed especially effectively in curing stiffness in the shoulder. So this stiffness massager can strongly press the pinpoint safely without moving the user's body or the massager out of position for massaging away the stiffness. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  [Technical Field] The present invention relates to a loosening device that can easily and effectively perform a strong pressing massage on a shoulder, a neck, and a deep part in the vicinity in a relaxed lateral position.

There are many people who feel shoulder stiffness. In the conventional method of eliminating the stiffness of the shoulder, there is an expert manual therapy (for example, see Non-Patent Document 1).

Further, as a conventional instrument for eliminating shoulder stiffness, there is a high-quality chair-type massage device (see, for example, Patent Document 1).

There is also a local massage device (see, for example, Patent Document 2).

There is also a belt type massage device devised for them (see, for example, Patent Document 3).

The person with shoulder stiffness wants to have the strongest acupressure, massage, and relaxation, and the effective human body point is the pin point deep in the base of the shoulder and neck. The conventional massage means does not meet this requirement.

Illustrated basic technique Anma, massage, whole body adjustment by acupressure Shionogi Publishing Co., Ltd. March 1, 2006, pages 90-95, pages 2-8, JP 2005-000259 A Japanese Patent Laid-Open No. 2005-40288 JP 2001-198170 A

The problems of the conventional expert technique therapy, the high-class chair-type massage device, the local massage device, and the belt-type massage device described above will be described in order.

Non-Patent Document 1 describes a technique that is particularly effective in relieving stiff shoulders and that provides a strong acupressure massage effect for pinpoints deep in the shoulder and neck base that should be massaged most strongly. Not.

First of all, I will explain the problems of expert technique therapy.
When a specialist performs a surgical procedure, as shown in the non-patent literature (especially the upper left part of page 94, the first row of the interscapular region and the first point (standing position)), the patient is in a lateral position, The practitioner puts the thumbs of both hands over the patient so that strong acupressure in the direction perpendicular to the surface of the human body can be applied to the deep part of the base of the shoulder and neck. Shiatsu. Thus, it was a difficult and difficult procedure to perform strong pressing and massage because of physical strength and pain of the fingers. In addition, because the practitioner is a human being, even if the patient desires strong acupressure for that point, the practitioner is too hard, the finger is broken, the pride of the practitioner For a reason such as this, long-term treatment was not possible. In addition, there were many cases where it was not possible to use it at a convenient time, and of course it was expensive.

Next, problems of the high-grade chair-type massage device will be described.
In the high-class chair-type massage device, Patent Document 1, the method of loosening the skin is adopted so as to be pinched from both sides, but as shown above in Non-Patent Document 1 in the deep part of the base of the shoulder and neck. Applying strong acupressure is dangerous because it compresses the cervical spine from both sides. Therefore, it cannot be pressed strongly, so there is no strong acupressure in the deep part of the base of the shoulder and neck. Basic technique 1) Only a treatment such as a light rubbing method (a stroking method) was possible. If only one side is pressed, the structure and shape of the user's body will shift.
Also, most patients had strong stiffness on either one of the right and left sides, but they could only massage left and right evenly with respect to the shoulder and neck deep at the base of the neck. . And because of the elderly and other reasons, the spine was bent, and patients who could not extend the spine normally could not be treated effectively.

Next, I will explain the problem of the local massage device.
The local massage device, Patent Document 2, does not have a structure and shape that can apply strong acupressure to the deep part of the base of the shoulder and neck.
Taking an unreasonable posture and forcibly applying strong pressure to the base of the shoulder and neck will rub the skin and hurt the skin because the range of movement of the tip of the pressing part is wide.
And since it is not the structure and shape which can endure a strong press, it was easy to have trouble in parts. Then, when a pressing force was applied to the deep part of the base of the shoulder and neck, the main body was easily displaced in the direction of the head.
In addition, because it was used in the supine position, the line of sight turned to the ceiling, so I could not relax and receive treatment while watching TV.
Also, in order to receive treatment while reading a book, it was difficult to lift the hands and support the book.

Finally, the problems of the belt type massage device will be explained.
On the other hand, the belt type massager used to loosen the stiffness of the shoulder is proposed as in Patent Document 3, but it is pushed with both hands, so the hand and shoulder on the loosening side are also used. Therefore, it was less effective and very tired.

For this reason, patients suffering from sequelae of cerebral infarction were unable to effectively loosen the shoulders and neck on the side with severe sequelae.

The present invention is intended to solve the problems of such a conventional configuration, and can be enjoyed while enjoying watching TV or the like on the shoulders and necks deep in the base of the neck. The patient is able to perform effective, effective, strong acupressure treatment safely and for a sufficient amount of time, which can only be done for a short time, just by being in a relaxed lateral position and asking a specialist for the procedure. It aims to realize what can be done.

The present invention has been invented as a result of earnest and research in order to eliminate the above-mentioned drawbacks of the conventional techniques. When a person stabilizes the head in a lateral position, the root of the user's neck is invented. The protrusion part which protrudes diagonally toward is formed.

Since the invented protrusion directly presses the human body, it is difficult to be deformed when pressed, a rigid body, a hard body, as well as an elastic body that is easily deformed, a flexible material, etc. Use the structure and materials that make you feel soft and secure when touched.

Moreover, it can also be selected that a protrusion projecting obliquely toward the user's seventh cervical vertebra is formed.

And it can also select that the head mounting part which mounts a user's head forms.

Then, it is possible to select that the neck-side protrusion that hits the boundary between the user's head and neck is provided to face the oblique protrusion.

Moreover, it can also be selected that the projecting portions protruding obliquely are provided at an angle of 30 to 60 degrees from the main body of the loosening device.

It is also possible to select that the obliquely projecting protrusions can be driven.

Then, it is also possible to select that a pinpoint unwinding projection that is driven is provided at the upper end of the oblique projecting portion.

It can also be selected that it can be used as a pillow.

It can also be selected that it can be used as a bet.

Then, it is possible to select that the armrest is provided with a protrusion projecting obliquely and can be used as a sofa.

As described above, the stiffness remover of the present invention is particularly effective in relieving stiff shoulders, and finds pinpoints deep in the base of the shoulder and neck that should be massaged most strongly with acupressure. A strong acupressure massage effect can be applied to relieve the skin, and it can be used in an easy position called lateral position. It is possible to provide a high strength therapeutic device.

In addition, the type that uses a well-known drive device to release the litter while applying a strong pressing force to the pin point deep at the base of the shoulder and neck allows for effective lapping that is impossible even with expert procedures. Became.
The following describes in order the advantageous effects as compared with the prior art, expert manual therapy, high-grade chair-type massage device, local massager, and belt-type massager.

First of all, we will explain the advantageous effects compared to expert manual therapy.
When a specialist performs a surgical procedure, the strong acupressure from above is projected obliquely toward the base of the user's neck when the person according to the present invention stabilizes the head in a lateral position. By forming the protrusions to be formed, strong pressing in the direction perpendicular to the surface of the human body can be performed at the deep part of the base of the shoulder and neck as a strong pressing applied from below.
Since the stiffness remover of the present invention has strength and power, the patient can perform desired strong finger pressure for a necessary and sufficient time regardless of physical strength, finger failure, practitioner's pride, etc. . In addition, it can be used at a convenient time, and there is no charge for the type with no power. Even a powered type is very inexpensive. Reference page 5; 3) Strong finger pressure of compression method (male method); Reference page 4; 2) Acupuncture method (mom method); Reference page 7; 6) Strong rubbing method (fir, The method that combines the kneading method) is now possible. Furthermore, if a vibrator function is provided, the reference page 5), 4) A technique and treatment that cannot be performed by humans can be performed by a synergistic effect combining the tremor method (swaving method) at the same time, and the therapeutic effect is high. Crushing has become possible.

Next, an advantageous effect compared with a high-class chair-type massage apparatus will be described.
In the high-class chair-type massage device, Patent Document 1, a method of loosening the powder so as to be pinched from both sides is adopted. However, the present invention, the loosening device, strongly presses only one side in the lateral position. From both sides, there is no danger of squeezing the cervical spine, it can be pressed strongly, and the user's body will not be displaced. Therefore, it is possible to perform treatment with a difference in left and right in the deep part of the shoulder and neck base with a difference in left and right. In addition, effective treatment can be performed even for patients who are unable to extend the spine normally due to bending of the spine due to age.

Next, an advantageous effect compared with a local massager will be described.
Unlike a local massager, Patent Document 2, it has a structure and shape that can apply strong acupressure to the deep part of the base of the shoulder and neck. In addition, since the pressing force is applied to the weight of the head and the direction of the head, it is difficult to shift in the direction of the head.
In the effect of the present invention, the range of movement of the tip of the acupressure part of the scrubbing device that is not too wide, the skin between the clothes and the skin of the subject is not easily rubbed, so that the skin is less likely to hurt. And since it is the structure and shape which can endure strong press, it is hard to produce a malfunction in components. Due to these effects, only the skin becomes painful unless care is taken so that the finger does not slip on the skin, as specified in Reference Document 3, page 5 to line 7. Try to move the wrist and elbow joints while holding the part you want to hold firmly with your hand. It is now possible to perform the same procedure, procedure, and method as well as the procedure, procedure, and method of strong acupressure.
In addition, since the treatment is performed in the lateral position, the user can relax and receive the treatment while watching TV without looking toward the ceiling.
Also, when reading a book, it is easy to read the book with both hands lowered and placed on the floor.

Finally, an advantageous effect compared with the belt type massager will be described.
There is no need to press with both hands, and it is now possible to perform a strong pressing procedure by simply using a relaxed lateral position without using both hands and shoulders, as well as both hands.

In addition, patients suffering from sequelae of cerebral infarction can effectively loosen their shoulders and neck on the side with severe sequelae.

Then, by providing a function as a crusher in the bed, the headrest of the bedding, and the armrest of the sofa, while taking advantage of the cushioning properties of the bed and the sofa, in a relaxed position called lateral position, Strong acupressure and massage can be applied deep in the base of the neck.
And, using the space of the sofa armrest, bed and headrest of the bedding, it is possible to provide a machine function for strong shiatsu and massage at the deep part of the shoulder and neck base Became.

Hereinafter, embodiments of the present invention will be described with reference to FIGS.
In FIG. 1, the projecting portion 1 projecting obliquely is applied to the right shoulder and the base of the neck, the head is placed on the head mounting portion 2, and the loosening device is placed above the head by the weight of the head. It is a figure that prevents slipping off and strongly presses the loosening of the right shoulder and neck.
Moreover, since the bottom part 3 uses the material which is hard to slip, it is useful for the slip prevention. Although applicable to any type other than FIG. 1, the bottom portion 3 has a large area by a public means such as a slide, and there are some that give a sense of stability to the debonder.
In addition, the user can use it by shaking his body. A is the seventh cervical vertebra, B is the first thoracic vertebra, C is the second thoracic vertebra, and D is the first cervical vertebra.

In FIG. 2, the projecting portion 1 projecting diagonally is applied to the right shoulder and the base of the neck, and the base of the head and neck is placed on the neck-side projecting portion 4, so that the non-patent document page 91 Because the pressing force is applied in the same direction as the first figure, the present invention prevents the strainer from slipping toward the head, and strengthens the right shoulder and neck. It is the figure which is pressing. By the way, Non-patent document, page 92, 1st line, 4 posterior cervical region, between the fossa and the temporal region, the first point just below the skull, and the posterior cervical 1 point is also in the same direction as the first temporal region Since finger pressure is applied to the head, it is very difficult to shift in the head direction. Moreover, since the bottom part 3 uses the material which is hard to slip, it is useful for the slip prevention.
Some areas of the bottom 3 have a small area as shown in FIG. There is also a narrower type that can be moved and loosened on purpose using the bottom 3 as a fulcrum. In addition, all types of scouring devices can be used in such a way that the user shakes the body while keeping it stable.
And there is a thing which has a massage function in the wide range between the protrusion 1 which protrudes diagonally, and the neck side protrusion 4. FIG. In addition, there are some which have a massage function in a wide range from the neck-side protrusion 4 and the protrusion 1 obliquely protruding to the bottom 3.

3 is extended compared with the embodiment of FIG. 2, and the head mounting part 2 is integrally formed. While relaxing, you can continue the massage for as long as you like.

FIG. 4 shows the shape and structure of FIG. 1 without the head rest 2 of the loosening device, in which a normal pillow is used instead of the head rest 2, and a cushion is used separately. is there.

FIG. 5 (1) illustrates an example of an overall view of the invented debonder.
The projecting portions 5 projecting obliquely are divided and opened to adjust the width, but are not separated in FIG. The neck side protrusion 6 is the same as described above. And the width | variety of the protrusion 5 and the neck side protrusion 6 which protrude diagonally can also be adjusted. Although not shown in the drawing, a structure may be adopted in which the width between the protrusion 5 and the neck-side protrusion 6 that project obliquely is adjusted or driven. As described above, the looseness on the shoulder side and the looseness on the neck side can be adjusted and driven in various ways suitable for the user's feeling of use. This function described above is a function that can be performed by all types of squeezers. Moreover, the pillow height adjustment part 7 can select height. The function of adjusting the height is a function that is possible with all types of squeezers.

(2) is a projecting portion 9 projecting obliquely and a projecting portion 8 projecting diagonally, and a projecting portion 8 projecting obliquely and a neck side projecting portion 6. On the protrusion 8 projecting obliquely and the protrusion 9 projecting obliquely, there is a pinpoint loosening protrusion 10 that moves by a driving source provided therein when strongly pressed. It rotates within a range that does not rub the skin too much even when pressed strongly, and can be driven to draw a small circle, thereby exerting a boring effect.
Further, the projecting portions 5 and 8 projecting obliquely have the same position as the projecting portion 1 projecting obliquely and the neck projecting portion 6 and the projecting portion 9 projecting obliquely and the projecting portion 4. Is appropriate. Then, it can be adjusted and driven as shown by the arrow as in (1).

6 (1) to 6 (10) show that the human body used in any strong pressing massage part of the projecting parts 1, 5, 8, 9 and the neck side projecting parts 4 and 6 projecting diagonally is strongly strengthened. Here are a few examples of the acupressure massager that strongly massages acupressure.

(1) is a powerful acupressure plus a fir tree effect, which is rotated by power to the tip of the contact portion divided by the projecting portions 1, 5, 8, 9 and the neck side projecting portions 4, 6 projecting diagonally The pinpoint unraveling protrusion 10 is loosened. The rotation may be clockwise or opposite, and may be an intermediate portion other than the tip portion or a lower end portion. By this function, the method of male, rice, rice, kneading and kneading, which are described in Non-Patent Documents 1 and 4 to 7 in terms of technique therapy, can be performed at a time.

(2) is the vibrator 11, and each of the projecting portions 1, 5, 8, 9 and the neck-side projecting portions 4 and 6 projecting obliquely or the entirety as the vibrator 11 has a function of loosening the stiffness of the human body. . With this function, a method of shaking and tapping as described above in the above-mentioned Non-Patent Document 1 in terms of manual therapy is added, so that a method of masculine, mulching, sieving, tapping, tamping and kneading can be performed at once.

(3) has a roller unraveling part 12, and the roller unraveling part 12 is a state in which the roller moves inside the projecting parts of the projecting parts 1, 5, 8, 9 and the neck side projecting parts 4, 6 projecting diagonally. Is illustrated.

(4) has an effect of gripping due to the difference in roller widths of the projecting portions 1, 5, 8, 9 projecting obliquely and the rolling milling unit 13 in which the neck projecting units 4, 6 rotate. This is illustrated.

(5) to (7) have one to four pressing protrusions 14 that have a high effect of unraveling even if there is no power. Of course, the pressing protrusion 14 and the tip thereof may be of a type having power. There may be four or more.

(8) is an explanation of the fact that there are four pressing protrusions 14 but adjustment is possible in the direction of 12 arrows.

(9) shows that there is a shoulder pressing assisting portion 15, but when the shoulder pressing assisting portion 15 comes into contact with the shoulder and the base of the neck, the pressing force is easily applied to the inside of the human body, which is the direction of the arrow, and to the deep portion. .

(10) is a type in which the pressing protrusion 14 is moved up and down by power. When the pressing protrusion 14 is raised, the pressing protrusion 14 is pressed. When the pressing protrusion 14 is lowered, the pressing protrusion 14 is recessed, and the human body may not be pressed or compressed. It is explanation of. It moves like a mole hit. It is also an explanation that the pressing protrusion 14 moves up and down due to the pressing condition by an elastic body such as a spring without power.

FIG. 7 shows a speaker 16 for listening to ambient sounds. It is good also as a listening hole without providing the speaker 16.

8 (1), (5), and (7) have a mat portion 17 that prevents the loosening device from shifting. In particular, this function has a higher function of preventing the loosening device from slipping toward the head when pressing the base of the neck. Some of the mat portions 17 can be removed.
In (2), the mat portion 17 is rolled up and stored.
In (3), the mat portion 17 is folded and stored.
(4) and (6) are used when the mat 17 moves or twists easily and comfortably, and when the loosening device stimulates the scraped portion or when a stronger pressing force is required, A footrest 18 is provided at the end of the mat 17 so that a foot can be further applied.

9 (1) and 9 (2), the whole is an L-shaped scraping device 19, which is easy to use in the right and left lateral positions. In addition, it has a shape that fits tightly from the base of the neck to the shoulders, the vicinity, and the back, so that a strong pressing massage can be performed. There is also a pinpoint loosening projection 20 and a vibrator 21.

FIG. 10 applies to all of the present invention loosening devices, but from Reference 2 page 35 line to page 3 line 16; Anma, massage, acupressure tips are written, but when the patient himself performs what is written, it is better to perform using the present invention loosening device that strongly acupressures only one side in the lateral position It is easier to perform for the deep part of the base of the shoulder and neck. As an example of the method of use, as shown in FIG. 10, the upper limb that is not strongly acupressured is moved to the full range of motion of the joint movement, and the protrusion 1 that protrudes diagonally is pressed more strongly by removing the force. It is an explanation.

In FIG. 11 (1), the massage function part 22 can also be provided in the present invention, the extension part of the loosening device. (2) can also provide the massage function part 23 in the present invention, the extension part of the loosening device.

FIG. 12 is an explanation of the fact that it can be used as a bet.
The user is in a lateral position on the bed 24 and uses the loosening function provided on the headrest 25. Although not shown in the figure, when using the loosening function, the cover or part may be opened or removed by known means, and the loosening function may appear. It is. And the height of the tearing function can be adjusted.

FIG. 13 (1) is an explanation of the fact that the armrest 26 is provided with the protrusion 1 projecting obliquely and can be used as the sofa 27. The figure shows that the user is in a recumbent position, the body is in close contact with the backrest part 28 and the seating surface part 29, and the deeper part of the shoulder and the base of the neck is strongly massaged and massaged by the stiffness release function provided in the armrest part 26. It is. Although not shown in the figure, when using the loosening function, the cushioning function may appear by opening or removing the cushion part or part by known means, so the design is beautiful when not in use. Is. And the height of the tearing function can be adjusted. Naturally, it is possible to unravel at the armrests 26 on both sides.

FIG. 13 (2) is a view of the sofa 27 of FIG. 13 (1) seen from the back side of the human body seen through from the back side. The deep part of the root of the shoulder and neck is strongly acupressure and massaged by the loosening function provided in the armrest 26, but also from the backrest 28 and the seat surface 29 as an example of an arrow. However, acupressure massage may be applied to each part of the human body.
As for arrow E, it applies to all of the loosening devices, but because the scapula rotates outward, it is hidden and cannot be touched in the normal position, the back of the scapula, the muscle of the spine standing muscle It is an explanation of relaxing. As a result, acupressure and massage can be performed with a stretch effect.

Up to now, the functions described above are functions that are possible with all types of squeezers, and several features of each type can be combined.

The following briefly describes the present invention, the features for all the litter and the approach to medical muscles, nerves, etc.

The human body grounding surface is a structure that allows you to feel softness and security when touching the human body by using elastic bodies, flexible materials, etc., rigid bodies, such as via springs, etc. It may be a material. Moreover, it may be manufactured in a shape in which a portion where the spine may hit is recessed.

When there is strong stiffness on the shoulder side, the head side has a large area with light pressure and stimulation, and the shoulder side has a small area with strong pressure and stimulation. In addition, by changing the combination, for example, by changing the combination, the feeling of use of the protrusions that match the base of the neck on the head side and the shoulder side is taken into consideration. As a method, there is a type in which the protrusion can be replaced.

It can also be adjusted to raise or lower only the shoulder side or only the head side.
And each protrusion of the protrusion can adjust each protrusion and the width of each protrusion, the width of each protrusion, the height of each protrusion itself, etc. it can.

And when a strong pressing force is applied, the direction of the strong pressing force applied to the human body by the strainer is the same as the direction of the stiffness at the base of the shoulder and the base of the neck. Since a force is applied in the downward direction to hold down the debonder, the structure of the debonder itself is difficult to shift.

Then, there is also a power that has a function of massaging the protrusion. As for the massage function using motive power, a known massage function using motive power is used, such as a protrusion and an uneven portion on the upper surface of the protrusion, such as rotation, vibration, and slide, as well as the protrusion.

As a supplement, if the protrusion that presses and massages the human body is a power type, it is movable as a whole, partially movable, and only the tip is movable by a known driving device. In addition, there is also a loosening device in which the entire loosening device is vibrated, movable, or combined with vibration, movable, and beat. And there may be provided a remote control or a switch that can select the timer function, massage, strength, and combination.

Since there is a type in which the protrusion is moved up and down by power, when the protrusion is lowered, there is a case where the protrusion is recessed and does not press or compress the human body. Some types without power have the same vertical function.

In the conventional massage device, the user presses in a supine position or a supine position to a sitting position, so that the scapula is close to the spine. By the way, the scapula is closer to the vertebral column than when the human is standing up, so the erector spine and the muscles behind the scapula are hidden, and it is impossible to press and loosen the stiffness.

On the other hand, in the present invention, the scapula is used in a lateral position, and the scapula is rotated outwardly to a posture away from the spinal column. In the position, it became possible to loosen upright spine, other muscles, and stiff parts that could not be loosened by disturbing the scapula.

In addition, the posture is a stretched state of the muscle that connects the upper limb to the spinal column, with the origin being the spine and the stop being the scapula. The method of pressing and loosening the elastic muscles while stretching the elastic muscles is a very effective method of loosening the stiffness. This theory is medically effective in the treatment of the human body.

In addition, it is effective in relieving stiff shoulders from medical books, literature, etc., and the muscles of the neck, shoulders, and nearby areas to be massaged with shiatsu massage are the rhomboid muscles, the scapula levator muscles, the subclavian muscles, and the supraspinatus The control nerves of the subspinous muscle, the subscapular muscle, the great circular muscle, the small circular muscle, the triangular muscle, and the upper limb muscle appear in the vicinity of the neck and shoulder from the cervical vertebra C4 to the thoracic vertebra TH2. By pressing the left and right sides of the spine from the cervical vertebra C4 to the thoracic vertebra TH2 one by one, it is possible to effectively relax the stiffness at the base of the neck and shoulder. Of course, it is possible to loosen from C1 to C3 with a protrusion that presses and massages the base of the neck of the head. And since a bundle of nerves called brachial plexus passes through the deep part of the shoulder and neck, it is highly effective to perform acupressure and massage.

However, it is not so wide, and a pinpoint deep in the base of the shoulder and neck that has a special therapeutic effect that is not found in medical books and literature etc. The skin, which is the part, can be loosened by applying a part to be loosened and starting to press, and by releasing the pinch point after the affected part is loosened little by little by the crushing effect and the strong pressing effect. I was able to discover this pinpoint unraveling method because it was an inventor who had been practicing research after many years of creative ingenuity. It is an invention based on the results of many years of studying whether it can be effectively loosened.
