Description

Massage Machine {Massage machine}

The present invention relates to a massage device, in particular, by optimizing the contact angle to the human body of the massage wheel performing massage, such as kneading, tapping, pressing, narrowing and widening the area to be massaged by directly contacting the human body It's about a massage that you can receive.

The marvelous development of modern medicine has reached a level where it can identify and uncover the secrets of human genetic makeup, the mystery of life. Therefore, the causes of various diseases that can be identified as a disposition, and methods for treating them have also been rapidly developed. As a result, human life is prolonged, and public interest and understanding of health has reached a high level. Nevertheless, modern people are suffering from anti-health syndromes due to their lack of environmental pollution, food pollution and complex lifestyles. Most of these syndromes are functional ones that are not confirmed by modern medical diagnosis, and their solutions are difficult.

Now it is time for us to extend the natural way of thinking and observe the gestures for self-protection of ancient predecessors or animals living in the natural environment. If you rub your neck and shoulders when you're feeling stiff, your whole body becomes lighter, you're not digestive, your chest is stuffy, or your back or cuffs are squeezed and you're relaxed. If we give, we have memories of pain disappearing. These methods are the basis for massage appearance.

These methods have many people interested in knowing when and who discovered them. However, there is no clear evidence in the literature. When we bumped into our hands and rubbed on the painful area, the pain is gone, or when the close family suffers from head or stomach aches and can't sleep, even a person with no medical knowledge can't see the pain. Holding, pressing, tapping, or sweeping the receiving area has been done at home.

Self-protection instincts and cognitive assumptions are the basis for the emergence of massage therapy. Therefore, it can be said that this method appeared in any region where humanity lives. People in each area practiced on their skin or dressed according to their lifestyle and habits.

Various methods have been developed, such as kneading or sweeping down. These methods are called 'massage' as the representative scientific name of the East.

Between AD 641 and 701, they were adopted by the Tang Dynasty in China and Japan in the sense of authenticity and courtship. In the West, the combined name of these methods was called 'massage'. In addition, these therapies are known as Chuna in China, Momirochi in Japan, Alps in the Middle East, and acupressure and acupoint massage in Japan. It is to be understood, however, that the rationale has only emerged as the sum total of manual therapy. Looking at the way these methods have evolved, they started out as a natural remedy, first organized in accordance with the characteristics of each region as folk remedies, and have undergone a common transformation process that has been legalized as a professional technical occupation in modern times.

In the case of the Orient, the massage is based on the philosophical idea of the Asian view of the universe and the human body. The Orientals thought that each human being was a microcosm that emerged with the energy of heaven and earth. Therefore, the material that makes the body is the body, and it has the energy to move this material in accordance with principle or reason, so as to maintain the vitality of man. Therefore, the force that raises the body and the vital force, the group must coexist and circulate, this stagnation of blood, stagnated or lacked or excessively considered to be sick. The paths in the human body that these blood donations operate are called Meridian, and the way that blood flows through the whole body's meridians without breaks is called 'Opian' or 'massage'. The method uses a variety of methods to rub, sweep, press, tremble, tap, pull, and exercise the whole body, including choked or inadequate parts, which are called 'cycles of massage' (hand techniques). If so, how should we massage when we have health problems? The first thing to do is to investigate the cause or area of the syndrome. This can be done by experienced family members and can be referred to a professional masseur. Thus, once the contents of the syndrome are confirmed, they are treated by professional masseurs, learn the self-massage methods that can be done in the house, and each person implements them. Ask yourself how.

However, in modern life, there are times when it is impossible to get a massage when it is necessary because the conditions such as time do not fit to go to a professional or daily massage.

In order to solve this problem, various massage devices have been developed, in which a machine can perform massage on behalf of the patient.

Various massagers are known to relieve firm muscles and stiffness by compressing and stimulating a person's shoulders and waist. If these devices are classified into types, chair type, needle type, hand grip type, and the like can be cited. The type of action on the affected area includes acupressure type, vibration type, and electrical stimulation type.

The massage chair used in the massage chair performs functions such as kneading, tapping, pressing, narrowing and widening while operating in the up, down or left and right directions.

Referring to the conventional massager, as shown in FIG. 1, a general massage chair includes a rotating shaft 7 which is rotated by the driving force of the motor 3, and a disc 8 which is eccentrically fixed from the shaft in a state inclined to both sides of the rotating shaft. ), A massage wheel 9 with rotation freely coupled to the outer circumferential surface of the disc, and a power transmission means for transmitting the power of the motor to the rotating shaft. Accordingly, when the motor 1 is driven, the rotating shaft 7 and the disc 8 rotate, and the massage wheel 9 rotates with a predetermined displacement in accordance with the rotational movement of the disc to press, narrow and widen the massage. Perform the action. In the massage chair structure, when the massage wheel 9 is displaced at regular intervals, the rhythmic massage effect cannot be obtained. Therefore, a mechanism capable of varying the angular velocity ratio of the rotating shaft 7 is installed on the power transmission path. Is common. In addition, the power transmission path is fixed integrally with the pulley of the motor (3) and the pulley (4) connected by a belt, the worm (5) integrally fixed to the pulley, the worm wheel (6) engaged with the worm (5), integrally with the worm wheel Drive gear (1), driven gear (2) engaged with the drive gear in a fixed state on the rotating shaft, and changes the angular velocity ratio of the rotating shaft by varying the shape of the drive gear and the driven gear in the power transmission path I'm making it.

For example, in Japanese Patent Laid-Open Nos. 57-84052, 60-145140, 60-145141, 60-145142, etc., the drive shaft and the driven gear are elliptical gears, and the rotating shaft can have a constant angular velocity ratio. In addition, Japanese Laid-Open Patent Publication Nos. 60-145142 and 59-2740 use a leaf gear and a universal joint, respectively, to obtain a constant angular velocity ratio of the rotating shaft. In addition, Japanese Patent Publications Nos. 55-37257, 55-48816, 59-22528, 56-44753, etc., use the rapid return principle by crank and four-section link so that the rotating shaft can obtain a constant angular velocity ratio. Doing.

However, in the case of conventional massagers, in particular, using massage wheels, the contact angle to the human body of the massage wheel that performs massage such as kneading, tapping, pressing, narrowing and widening the parts to be massaged by directly contacting the human body. Without any consideration, the massage wheel is simply in contact with the human body in a vertically arranged state, so when the massage is performed by the actual massage device, only the corner of the massage wheel comes into contact with the human body. There was a problem that the skin is folded and bitten, and even if not, there was a problem such that only the corner portion of the massage wheel is in contact with the human body, thereby limiting the area of the massage area.

The present invention optimizes the contact angle to the human body of the massage wheel performing massage, such as kneading, tapping, pressing, narrowing and widening the area to be massaged by directly contacting the human body to receive a more effective massage The purpose is to provide.

It is good.

The first link member 11 includes a first link arm 111 and a second link arm 112, and is bent by mechanical properties, in particular by external force, by bending one edge by processing one steel plate. It can be configured by improving the bending resistance to prevent. In particular, by processing one iron plate to form the first link member 11, the production process can be simplified to improve productivity and to enhance durability. The first link body 11, the first link arm 111, and the second link arm 112 may be integrally formed. In addition, rotatably fixing the first massage wheel 113 and the second massage wheel 123 to the ends of the first link arm 111 and the second link arm 112 is also a common shaft and bearing Can be fixed using such as can be understood to be easily implemented by those skilled in the art.

The second link body 12 including the third link arm 121 and the fourth link arm 122 may also be formed in the opposite direction to the first link body 11 and the rest of the link body 12 may be the same.

It will be understood that the first link member 11 and the second link member 12 may also be formed by molding a synthetic resin by injection molding or extrusion molding.

The third link body 13 and the fourth link body 14 may also be molded in the same or similar manner as the first link body 11 and the second link body 12.

In particular, the third link member 13 includes a fifth link arm 131 and a sixth link arm 132, and is rotatable to the second link arm 112 of the first link member 11. Is connected.

In addition, the fourth link member 14 is configured to include a seventh link arm 141 and an eighth link arm 142 and rotates to the fourth link arm 122 of the second link member 12. Possibly connected.

Accordingly, the first link body 11 and the third link body 13 connected thereto, and the second link body 12 and the fourth link body 14 connected thereto may be the first link body 11. ) And the second link member 12 are fixed to the drive shaft 16, and the drive shaft 16 is fixed to the housing H by a pair of axial housings 19, and fixed to the housing H. The link housing is configured to be rotatably fixed with respect to the housing (H) by the conical housing (19).

End portions of the first link arm 111, the third link arm 121, the fifth link arm 131, the sixth link arm 132, the seventh link arm 141, and the eighth link arm 142. The first massage wheel 113, the second massage wheel 123, the third massage wheel 133, the fourth massage wheel 134, the fifth massage wheel 143 and the sixth massage wheel 144, respectively. Are rotatably fixed. The massage wheels are in contact with the human body, and the first link body 11 and the second link body 12 are fixed to the drive shaft 16 driven by the motor 15, as shown in FIG. 8. An eccentric cam 18 is interposed between the drive shaft 16 and the first link body 11 and the second link body 12 to rotate the drive shaft 16 so that the first link body 11 and The second link bodies 12 are fixed to oscillate in accordance with the eccentric movement of the eccentric cam 18, such as kneading, tapping, pressing, narrowing and widening the skin of the human body by oscillating movement of the link bodies. Massage will be performed. Eccentric cam 18 is fixed to the drive shaft 16 as shown in Figure 8 and the bearing 181 connected thereto is just one example for the operation of the massage device of the present invention, the present invention is limited thereto. It will be apparent to those skilled in the art that the eccentric cam 18 can be variously modified to form various rocking motions.

2 and 5, the drive shaft 16 is driven by the motor 15, the mechanical connection between them is as follows. First, the rotational force of the motor 15 fixed to the housing H rotates the motor pulley 20 connected to the motor shaft of the motor 15, and one side of the electric belt 17 is connected to the motor pulley 20. The driven pulley 21 is connected to the other side of the transmission belt 17. A worm 22 is connected to the driven pulley 21, and a worm wheel 23 is geared to the worm 22 by gear teeth, so that a continuous rotational movement of the driven pulley 21 in one direction is achieved. It can be converted to the rotational motion of the worm wheel 23 while changing only the direction of rotation. The drive shaft 16 is fixed to the worm wheel 23, and driven according to the rotational movement of the worm wheel 23 to rotate, and the eccentric cam 18 according to the rotational movement of the drive shaft 16. This rotational movement will eventually cause the link bodies to swing in accordance with the rotation of the eccentric cam 18.

Particularly, in the present invention, as shown in FIGS. 2 to 4, the first link arm 111 and the second link arm 122 may have a first deflection angle with respect to the centerline of the first link member 11. and the third link arm 121 and the fourth link arm 122 are formed to be deflected at a first deflection angle α with respect to the center line of the second link member 12. It is characterized by. Therefore, the interval between the first massage wheel 113 and the second massage wheel 123 and the interval between the third massage wheel 133 and the fifth massage wheel 143 and the fourth massage wheel 134 and the sixth massage By varying the intervals between the wheels 144, it is possible to form a variety of massage space to be placed between the massage wheels of the various parts of the human body to receive a massage.

The first deflection angle α may be an angle within a range of 5 to 15 degrees. When the first deflection angle α is formed to be less than 5 °, there may be a problem that the difference in the distance between the massage wheels as described above is not large so that various changes in the massage space are not made. When it exceeds °, the deflection angle of the link arms with respect to the link bodies is too large to weaken the mechanical durability, and the massage spaces are too wide to form an effective massage space for the human body There may be. The first deflection angle α may be 10 °.

The first link arm 111 is deflected so as to be widened outward with respect to the first link member 11 at the first deflection angle α, and likewise, the second link arm 112 is connected to the first link member. It can be deflected to widen outward with respect to (11) at the first deflection angle α, thereby providing various massage spaces.

In addition, as shown in FIG. 7, the third massage wheel 133, the fourth massage wheel 134, and the fifth massage wheel 143 and the sixth massage wheel 144 are perpendicular to the housing H. It may be fixed to be deflected at a second deflection angle β with respect to the vertical line extending in the direction. The second deflection angle β may be 5 to 15 °, preferably 10 °. When the second deflection angle β is less than 5 ° or more than 15 °, there may be a problem in that the contact angle of the massage wheel to the human body is greatly modified to impart a comfortable massage effect, but the present invention is limited thereto. It can be understood that the enemy can be adjusted according to the shape of the massage wheel. Deflecting and fixing the massage wheels to the second deflection angle β biases the axis of rotation of the massage wheels fixed to the link arms in fixing the massage wheels to the link arms or the link wheels. This can be achieved by deflecting the link bodies themselves in which the arms are integrally formed.

By deflecting the massage wheels at the second deflection angle β as described above, in particular, when the massage wheels come into contact with the human body, they are brought into close contact with a wider range than the corners of the massage wheels. The friction part becomes wider, and the human body is brought into contact between the round bottom parts, not the corners of the massage wheel, thereby preventing the problems of folding the skin between the massage wheels. It has the advantage of enabling efficient massage.

As shown in FIG. 6, the first link member 11 may further include a stopper 41 for supporting the fifth link arm 131 of the third link member 13. The stopper 41 is formed integrally with the first link member 11, and is formed to be located close to the rear surface of the fifth link arm 131 of the third link member 13. (13) is rotatably coupled to the first link body 11 to prevent the fifth link arm 131 and the sixth link arm 132 is rotatably fixed to prevent excessive movement, in particular the user In the case where it is required to support a large body area, such as when the back part is to be massaged, the whole of the third link body 13 is limited to a certain range, and is rotated by the first link body 11. It can be firmly supported. In particular, a torsion spring 31 is installed at the rotational shaft located at the center of the third link member 13 to impart an elastic force that always pushes the sixth link arm 132 of the third link member 13 forward. When the user touches the fourth massage wheel 134 of the sixth link arm 132 with the back, the fourth massage wheel 134 is continuously operated by the elastic force of the torsion spring 31. The third massage wheel 133 of the fifth link arm 131 at the position opposite to the sixth link arm 132 may be brought into close contact with the back of the user.

Similarly, the fourth link arm 122 of the second link member 12 may include a stopper 41 for supporting the seventh link arm 141 of the fourth link member 14.

Therefore, the massage device according to the present invention having the configuration features as described above provides a variety of massage spaces formed between the massage wheels, and also maximize the massage effect by allowing the massage wheel and the user's body to be as wide as possible. You have the advantage of having it.

Such an effect according to the present invention has also been demonstrated by a sensory test, and according to the present invention, the first deflection angle α is set to 10 °, and the first link arm 111 with respect to the first link member 11 is outside. And a massaging device (example) prepared by deflecting the second link arm 112 with respect to the first link member 11 to be narrowed inwardly, and by setting the second deflection angle β to 10 °. Except not deflected by the deflection angles, a conventional massaging device (comparative example) having the same configuration is subjected to massage for 30 adult men and women, one person each of the examples and comparative examples In order to evaluate the feeling of using the sequential use, as a result of the experiment, 26 people (87%) determined that the massage of the embodiment gives a better feeling compared to the comparative example of the 30 participants, the present invention Massage is more pleasant to the user It was confirmed that the massage can be provided.

The invention can be used in the manufacture of massagers and in the industries using them.
