Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chair type massage machine and its operation control method.

[0002]

2. Description of the Related Art Conventionally, a chair-type massage machine has been developed in which the height at which the user performs a massage operation can be automatically changed according to the sitting height level of the user (patented). No. 2511451). In this massage machine, the operation part for performing fir, rubbing, etc., called a "treatment element," is temporarily raised to the upper limit height before starting the massage operation, and then lowered to the user's shoulder. The abutment position is determined based on the detection signal from the pressure sensor built into the massager at this time, and this abutment height position is set as the origin of a series of subsequent massage operations. The programmed massage operation is sequentially executed from the origin (that is, the shoulder position) upward or downward.

That is, although the sitting height level of a human has a large difference due to differences in height and the like, the distance from the shoulder level to the neck level and the distance from the hip level to each other are different when the provisional decree and the sitting height level are different. However, with the recognition that there is a substantially constant ratio relationship, the expected distance from the origin to the neck position and the expected distance from the origin to the shoulder or waist position are standardized numerical data, that is, the vertical direction. It was stored as the required number of points to occupy in the row of a plurality of points set in the above, and this was shifted in the point row as needed after setting the origin.

[0004]

However, as a result of actually using this massage machine by a large number of persons having various height differences, it is possible to obtain a uniformly and sufficiently satisfactory therapeutic effect by the massage. Was not. It is not clear in the publication disclosing the above-mentioned conventional massage machine that there is no explanation of the grounds for determining the numerical data, but according to the applicant's inference, this numerical data is from the origin (shoulder position) to the neck position. It is thought that this is because the vague expected distance to the area around the shoulders or the waist or the like, and the technical idea of merely allowing the treatment element to reach "around that".

The human body shape is not so simple and clear as based on the above recognition, and even if the vague numerical control as described above is performed, it does not make much sense. In other words, in order to exert the therapeutic effect of the massage, it is necessary to appropriately stimulate the acupuncture points having individual positions, and vague numerical control is not sufficient. The present invention has been made in view of the above circumstances, and a chair-type massage machine capable of stimulating an appropriate acupoint regardless of the difference in height and obtaining a uniformly sufficient and satisfactory therapeutic effect. And an operation control method.

[0006]

In order to achieve the above object, the present invention takes the following technical means. That is, in the chair-type massage machine according to the present invention, the backrest provided with an operator that performs a massage operation (this operator includes not only fir balls but also an operating portion for performing acupressure, tapping, rubbing, etc.). Section and a movement drive section for moving the motion element along the height direction of the backrest section, and the movement drive section is moved to a specific position on the back side of the user, which is a pot position. A position controller for stopping the child is provided.

The specific position in this case is the position of each acupuncture point and is expressed with the shoulder position as a reference. However, the reference position is not limited to the shoulder position, but may be the back position of the body such as the waist position. It may be any part on the side. However, the specific position information for determining the specific position, the height measurement targeting a large number of people in advance, and the distance measurement between the predetermined parts of the body (for example, the size between the shoulder and waist), Is the average position data obtained by aggregating for each predetermined height range and calculating the average value. That is, this specific position information is
It is based on statistics.

When the user selects and inputs his / her own height into the position control unit during the starting operation, the position control unit selects the height from the plurality of specific position information stored. Those that are compatible with are selected and read out. Then, the position control unit controls the movement amount of the movement element by the movement drive unit based on the read specific position information. That is, the present invention, not only when there is a difference in sitting height level, the difference in age and sex,
Alternatively, there are a wide variety of body features, etc., and when considering their combinations, etc., it is not possible to control by adapting to everybody with only uniform numerical data that is vaguely decided. It is based on the knowledge that it is, and for that reason, not only the height difference, but also the data is collected from many people who differ in age, sex, body type, etc.

In particular, in the present invention, the principle of massaging acupoints is emphasized in order to relieve the stiffness of the mind and body, and
Focusing on that the acupuncture points for this are lined up on both sides along the spine, the specific position information to be stored in the position control unit,
It is supposed to indicate a plurality of acupuncture points arranged along the spine. Therefore, when data is collected from a large number of humans as described above, position data of a predetermined acupoint is collected. Data collection for this acupoint position may be measured depending on medical data, but instructions, tactile sensations, and in some cases data collection targets based on empirical rules of acupressure and acupuncturists, or those involved in the massage industry. It is preferable to take into consideration the impressions of the people.

[0010] In particular, if you are an expert such as a Shiatsu doctor, you will be asked for the purpose of massage (for example, recovery of general muscle fatigue, improvement of built-in function, improvement of bowel movement, improvement of low back pain, etc.), height and sex. Also, since he is well aware of subtle differences in acupoint positions due to combinations with age, body type, medical history, etc., a very good massage effect can be obtained. Note that it is not necessary to set all the specific position information to the pot position, for example, set specific position information indicating the “origin” at a predetermined position near the shoulder, and set the other specific position information as the pot position based on the origin. The other specific position information may be measured in a distance.

After the actuator is moved to the position control unit based on predetermined specific position information, the position control unit can be finely moved in the height direction of the backrest from the specific position (that is, by an artificial switch operation. If there is a slight difference between the average acupoint position and the actual acupoint position, it is possible to operate the child by an arbitrary amount or to have a configuration that allows massage while finely moving the actuator within a certain range from a specific position). Can also handle. In addition, when the user changes the posture, there is a slight shift in the stiffness position, there is a wound on the body part corresponding to the specific position information, or when it is tailored to personal preference, be sure You can massage the acupoint position.

When the position control section is provided with a position display section for informing the user of the current position of the operator, the user can grasp the progress of the massage, and when the stiffness is particularly strong. You can manage your own health, etc., and it will be convenient when you want to massage the area. In this case, the position display unit may be a voice, a sound (buzzer), light, or the like. On the other hand, in the operation control method of the chair-type massage machine according to the present invention, the position data at the plurality of acupoints arranged along the spine are collected from a large number of people having different heights, and these are divided for each predetermined height range. The average position data is calculated for each of the above, and the average position data is stored in advance as the specific position information.

Then, when the height is input during the starting operation, the height range classification that matches this height is selected,
A plurality of specific position information written in this, that is,
A part or the whole is read from the acupoint position, and the movement drive unit is operated while maintaining a predetermined time for performing a massage operation for each read specific position information. is there. Therefore, a highly effective massage is performed on the whole body or partial area of the user under automatic driving.

The time interval for moving the movement element (massage drive unit) between the specific position information, the moving order thereof, and the combination of the specific position information itself can be appropriately changed according to the purpose of the massage. is there.

[0015]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. The chair type massage machine 1 according to the present invention will be described with reference to the external view illustrated in FIG. 1. As its basic configuration, a chair body 2 and an operator provided on a backrest portion 3 of the chair body 2 are provided. It has a massage drive unit 5 for massaging 4 and a movement drive unit 6 for moving the massage drive unit 5 along the height direction of the backrest 3.

Although not shown in the figure, a position control section as a circuit for controlling the operating state of the movement drive section 6 is provided for the movement drive section 6. The control by this position control unit is
The massage drive unit 5 is stopped in order to match the motion element 4 to a specific position on the back side of the user, for example, the acupoint position shown in FIG. 2 (which is the “acupuncture point” in terms of Oriental medicine). It is something to do. The device configuration of the massage machine 1 according to the present invention is not particularly limited as long as it has the above basic configuration. Therefore, in the following, Japanese Patent Application No. 8-185258
The case of applying the one having substantially the same configuration as that described in the application specification related to the issue will be described.

In the chair body 2 of the illustrated example, the seat surface portion 8 is supported by the left and right legs 10 integrally provided with the armrests 9, and the footrest 11 is provided at the front portion of the seat surface portion 8. It has been set. The footrest 11 and the backrest portion 3 are for reclining,
The angle with respect to the seat surface portion 8 can be changed by an electric mechanism or a fluid pressure drive mechanism (not shown) as appropriate.
The seat surface portion 8 itself is also capable of a certain amount of back-and-forth movement, vertical movement, and the like as the angles of the footrest 11 and the backrest portion 3 are changed.

The movement drive unit 6 causes the feed screw 14 provided along the height direction of the backrest 3 to be screwed with the massage drive unit 5, and the feed screw 14 is connected to an electric motor or the like. The massage drive unit 5 can be moved to the user's neck side or hip side by rotating the forward / backward rotation with the driving unit 15 provided. It should be noted that, in addition to this, as the movement drive unit 6, it is also possible to adopt a winding drive mechanism, a meshing structure of a rack and a pinion, a linear movement means using a fluid pressure cylinder or the like.

The massage drive unit 5 is shown in FIGS.
And a base frame 17 that can be moved directly by the movement drive unit 6, as shown in FIG.
A rocking plate 19 which is provided via a pair of left and right side link mechanisms 18 and whose upper and lower ends can be rocked back and forth, and a rocking plate interposed between the base frame 17 and the rocking plate 19. The moving plate driving part 21, the upper and lower link mechanisms 23 and 24 provided for the swing plate 19, and the respective link mechanisms 23 and 24,
24, and a link driving part 25 provided separately.

The operating element 4 described above is provided for each link mechanism 23, 24. Each of these operating elements 4 is formed as a roller rotatable about the horizontal axis, but the operating element 4 held by the upper link mechanism 23 is larger than the operating element 4 held by the lower link mechanism 24. The diameter is large, the height of the backrest portion 3 protruding is large, and the left-right spacing is wide. Since the upper and lower link mechanisms 23 and 24 have substantially the same structure, only the upper link mechanism 23 will be described with reference to FIGS. 3 and 4.

The upper link mechanism 23 has operator support frames 27, 28 provided so as to be capable of crossing and swinging with respect to a vertical axis 26 provided on both the left and right sides, and a link for restricting the swinging range of these. 29 and 30. The link driving part 25 described above is provided between each of the operator support frames 27 and 28 and the swing plate 19. An air cell having a bellows pump structure or a balloon structure is used for the link driving part 25. That is, when pressurized air is supplied to the link driving portion 25, axial expansion occurs, and the operator 4 projects obliquely forward with the vertical axis 26 as the center, and conversely, the link driving portion 25 is pressurized. Exhaust or suction of air causes axial contraction, and the operator 4 returns to the original state.

Therefore, by synchronously controlling the supply and discharge of the pressurized air to the left and right link drive parts 25, the left and right actuators 4 repeat mutual proximity and mutual separation, which causes the fir motion. It will happen. On the other hand, four oscillating plate drive parts 21 provided between the base frame 17 and the oscillating plate 19 are used at substantially the same position as the link drive part 25, as is clear from FIGS. 4 and 5. And
Of these four, the link driving part 2 of the upper link mechanism 23
The left and right two corresponding to No. 5, that is, the upper row, and the left and right two corresponding to the link driving part 25 of the lower link mechanism 24, that is, the lower row, are synchronized or exchanged with each other to supply the pressurized air. I am supposed to get rid of it.

Therefore, the pressurized air is supplied to and discharged from the oscillating plate motive portions 21 in the upper row and the oscillating plate motive portions 21 in the lower row in an alternating manner, so that the oscillating plate 19 is oscillated. As a result, the upper and lower motion elements 4 perform an up-and-down alternating movement. This causes the acupressure action and the tapping action. Further, by supplying and exhausting the pressurized air to and from the oscillating plate driving portions 21 in the upper row and the lower row at the same time, all the operating elements 4 start to move in and out synchronously. As a result, a finger-pressure operation or a tapping operation having a slightly different pattern from those described above are caused.

Now, in the massage machine 1 having such a device structure, the position control section for actuating the movement drive section 6 is applied to the user leaning on the backrest section 3 as described above. , To the specific position on its back
Can be matched. Therefore, the position control unit provides specific position information (this is dimensional information on the device side) for instructing the movement drive unit 6 to operate in accordance with these specific positions (this is dimensional information on the user side). It is stored in advance. The specific position information is obtained as follows when the specific position is an acupoint position arranged along the spine as shown in FIG.

That is, first, for a large number of people having different heights, the height measurement and the sitting height (Y1 dimension) measurement, and each acupoint position when the measurement point P on the shoulder side used in this sitting height measurement is the origin. Distance measurement (Y2 corresponding to lungs, Y3 corresponding to septum, Y4 corresponding to spleen, etc.). In this embodiment, the distance below Y2 is
The measurement is performed partially with reference to the positions adjacent to the upper side, but the present invention is not limited to this, and the distance may always be measured from the point P.

The dimensions Y2 to Y7 are only for typical acupoint positions, and the acupoint positions not included in these are included (shoulder-in-the-shoulder, stirrup-in-the-birth, heart-birth, ...
Etc.) may be used as a target, or, although not shown, there are more acupuncture points on the back side of a human, and the distance may be measured for them as necessary. Next, the individual data thus collected are divided into predetermined height ranges, and an average value is calculated for each division. Then, the average position data thus obtained is used as the specific position information.

Therefore, according to the present embodiment, the specific position information has a height range of approximately 3 cm to 5 c as shown in Table 1.
When divided into A to F at intervals of about m, they are obtained over Y1, Y2, ... Y7 for each division. In addition, Table 1 shows the results of data collection for each of the categories A to F with 100 or more data collection subjects.

[0028]

[Table 1]

In the position control section storing such specific position information, when the user sits on the chair body 2 and performs a starting operation, when he / she inputs his / her height, the position is selected from the above A to F categories. A section suitable for the height is selected, and the specific position information of Y1, Y2, ... Y7 written in this section is read out. Then, the position control unit sequentially instructs the movement drive unit 6 to perform a predetermined operation based on the read specific position information. For example, when the entered height matches the A category,
The position control section selects Y1 from the seat surface portion 8 of the chair body 2 by selecting the A section (that is, 53.4c).
It is determined that there is a point P (origin) at a position separated by m).

Then, the distance Y2 (that is, 6.) required for moving the upper or lower operator 4 of the massage drive unit 5 from the point P to the required pot position (for example, lung ax). 4 cm) and its moving direction are instructed to the movement driving unit 6. Of course, at this stage, it is necessary to take into consideration where the operator 4 is stopped,
Necessary operations for alignment are performed. At this time,
In order to detect the current position and movement distance of the movement element 4, a rotation speed detector (not shown) such as a rotary encoder or a rotary potentiometer is provided in the rotating portion of the feed screw 14 or the driving portion 15 of the movement driving unit 6. In advance, a method of calculating the moving distance of the massage drive unit 5 from the rotation speed may be adopted.

Instead of this, a rail member (see reference numeral 32 in FIG. 4) for guiding the movement of the massage driving unit 5 and a distance detector (not shown) such as a linear potentiometer are provided along the feed screw 14. , Massage drive 5
A detector (not shown) may be provided on the side and the moving distance thereof may be directly measured. After moving the motion element 4 to the target position as described above, the massage drive unit 5 performs a massage operation for a predetermined time, so that the lungs are massaged.

It is preferable that the position control section is configured such that the movement drive section 6 can be finely moved in the height direction after the operator 4 reaches the target position. That is, it is preferable that the operator be operated by an arbitrary amount by an artificial switch operation, or massage can be performed while moving the operator within a certain range from a specific position. The range of this tremor is
It is appropriate to set it to about 40 mm. In this way, even if there is a slight difference between the average position of the acupuncture points and the actual acupoint position, the acupoint position can be surely stimulated. In addition, when the user changes his posture after setting the P point (origin), there is a slight shift in the stiffness position, there is a wound in the body part corresponding to the specific position information, or personal preference is given. It is possible to respond flexibly even when matching.

Next, the position control unit determines the distance Y3 (that is, 9.3 cm) required for the actuator 4 to move from the current position to the next required pot position (for example, a distance). The movement direction is instructed to the movement drive unit 6. After that, the massage drive unit 5 performs a massage operation for a predetermined time, so that the massage is performed on the partition. As is clear from the above description, the operation time of the massage drive unit 5 is taken into consideration for the time interval at which the position control unit instructs the movement drive unit 6 to operate from one specific position information to the next specific position information. It has become a thing.

By repeating such an operation, a highly effective massage is performed on the whole body or partial area of the user under automatic driving.

[0035]

EXAMPLES Next, an example of a specific massage program will be described. 6 to 8 are flowcharts showing a procedure until the position control unit selects and executes a predetermined massage program at the same time when the user starts the position control unit. 3 shows a controller 40 for the user to perform a starting operation and the like.
This controller 40 is provided with a lid 41 that can be opened and closed on the operation surface. As shown in FIG. 9A, with the lid 41 open, various manual operations according to the user's preference are possible. And the lid 4 as shown in FIG. 9 (b).
With 1 closed, the automatic treatment course can be selected from a plurality of ways.

Below, the state where the lid 41 is closed will be mainly described. On the front surface side of the lid 41, a course selection portion 42 is provided in the lower half portion thereof, and the display surface portion 44 can be seen through the transparent cover portion 43 in the upper half portion. As the execution pattern of the automatic treatment course, the course selection unit 42 can select a total of 6 patterns of standard courses by independently using the number keys 1 to 6 arranged in an outer ring shape, and at the center of these number keys. A total of 6 can be obtained by combining the shortcut mode key and each number key.
You can select a shortened course of the pattern.

In the standard course, the acupressure at each acupoint position is repeated three times while the massage drive unit 5 is reciprocated twice by the movement drive unit 6, and the seat surface unit 8 and the footrest 11 are appropriately provided. The mechanism allows finger pressure to be applied to the outside of the lower limbs. The time required is about 15
Minutes. On the other hand, in the shortening course, the massage drive unit 5 is reciprocated by the movement drive unit 6 only once, and the finger pressure at each acupoint position is also only once. Further, the finger pressure for the lower limbs is omitted. However, the content of the massage operation itself is
It is basically the same as the one with the same number in the standard course. It takes about 5 minutes.

The outline of each course is as follows. Course 1 is a fatigue recovery course, in which the middle pressure, the heart pressure, and the liver pressure are massaged in this order by the normal pressure method, and then the kidney pressure is massaged by the gentle pressure method. The course 2 is a gastrointestinal improvement course, in which the urine and the stomach are massaged by the gentle pressure method after the massage of the incubus and the stomach is performed by the normal pressure method. Course 3 is a bowel movement improving course, in which Sankoyu is massaged by the normal pressure method, and then the large intestine and the small intestine are massaged by the gentle pressure method.

Course 4 is a liver injury improvement course,
After massaging the Yin-Yu and Sant-Yu by the normal pressure method, massage the Liver-Yoru and Sanjyo-Yo by the gentle pressure method. The course 5 is a low back pain improvement course in which the spleen is massaged by the normal pressure method, and then the kidney, the large intestine, and the small intestine are massaged by the gentle pressure method.
The course 6 is a neuralgia improvement course. For example, in the case of sciatica, the large intestine is massaged by the normal pressure method, the small intestine is massaged by the gentle pressure method, and then the legs and the like are pressed. In assisting neuralgia, a gentle pressure method is applied to the heart and a normal pressure method is applied to the heart, and then the legs are acupressure.

On the other hand, on the display surface section 44, a course display section 45 for displaying the fact that the automatic treatment course is being selected, the number of the selected course, etc., and the current position of the operator 4 are the light emitting points. The position display section 46 for displaying, the elapsed time display section 47 for displaying the remaining operation time, the strength display section 48 for displaying the strength of the massage force, and the like are provided. Here, the position display unit 46 displays (notifies) the position to the user by voice, sound (buzzer), light, or the like.
Good as a thing. In addition, in the controller 40, the lid 4
When 1 is opened, the course display section 45 is turned off, and in place of this, the display of "favorite manual course" is turned on. In addition, the course selection unit 42 is also substantially in a non-functioning state.

Then, an ascending step button 49 and a descending step button 50 are provided on the part hidden by the lid 41 (the part corresponding to the course selecting part 42). The up-and-down step button 49 and the down-and-step step button 50 can actuate the movement drive unit 6 only while the push operation is performed, whereby the operator 4 is stepped by an arbitrary amount. You can do it. This controller 40 has a lid 4
A power-on unit 52 is provided on the upper side of 1, and a height selection unit 53 is provided adjacent to the power-on unit 52. This height selection unit 53
It has a height setting button 54 and a plurality of display LEDs 55, and the display LED 55 can light up and display the height range selected by operating the height setting button 54.

Here, the height is selected from three ranges, one of which is the height of the user 165c.
When the height is less than m (corresponding to A, B and C classifications in Table 1), the next one is that the user's height exceeds 165 cm and
When the height is 75 cm or less (corresponding to the categories D and E in Table 1), the other one is when the user's height exceeds 175 cm and is 190 cm or less (corresponds to the category F in Table 1). ). By dividing the range as described above, it is possible to substantially correspond to the individual difference in the acupoint position, and if necessary, the acupoint position can be surely stimulated by the fine movement of the motion element 4.

The display LED 55 is provided corresponding to these ranges, and the LED 55 corresponding to the range selected by the height setting button 54 is turned on. At the lower end of the controller 40, a strength selection section 57 for selecting the strength of the massage force and a reclining adjustment section 58 of the chair body 2 are provided. Next, this controller 4
A procedure for setting an automatic treatment course using 0 will be described based on FIGS. 6 to 8. The controller 40 sequentially guides the input procedure by lighting the display section so that even a person unfamiliar with the operation can easily operate the controller 40. Therefore, when the power is first turned on, the user is first prompted to select the height (step 101).

Therefore, the user has steps 102 to 104.
As shown in, the height setting button 54 of the height selection unit 53 is pressed an appropriate number of times to select a range suitable for one's own height. As a result, the predetermined specific position information is read (see steps 105, 108 and 107). In addition, statistically 1
The height setting button 54 is not operated in order to take into consideration the fact that many people have a height of more than 65 cm and 175 cm or less, and to allow a person who is not accustomed to the operation to press the height setting button 54. In this case, it is programmed that the predetermined specific position information is read automatically assuming that the area of more than 165 cm and less than 175 cm is selected.

After this, the strength of the massage force is set according to the preference of the user (see step 109 to step 115). If you do not make this setting, the medium level is automatically selected. Next, the controller 40 displays a message requesting the selection of the course and prompts the user to perform a required operation (step 1).
16). To select a shortened course, first press the shortcut mode key, and then press the desired number key from 1 to 6 (see steps 118 to 124). Instead of pressing the mode key, the desired number key in 1 to 6 may be pressed as it is (see steps 131 to 136).

Therefore, the predetermined operation program is read and executed. The subsequent execution of the program is performed along each of the above-mentioned courses, and detailed description thereof will be omitted here. By the way, the present invention is not limited to the above embodiment. For example, the detailed structure of the massage drive unit 5, the shape and number of the movement elements 4, the detailed structure of the movement drive unit 6, and the like can be changed as appropriate. That is, as for the massage driving unit 5 and the like, not only the one using an air cell but also a mechanically operating structure may be used. Further, the chair-type massage machine according to the present invention includes not only a chair-type massage machine having the shape of a chair as a whole but also a chair-type massage machine that can be used while sitting on a chair by being attached to the backrest of the chair.

[0047]

As is apparent from the above description, the chair-type massage machine according to the present invention can stimulate appropriate acupoints regardless of the height difference of the user, and exert a therapeutic effect by massage. be able to. On the other hand, in the operation control method of the chair-type massage machine according to the present invention, it becomes possible to automatically and continuously massage each of the plurality of acupoint positions with respect to the whole body or partial area of the user, which is comfortable. Also, the massage effect becomes good.

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a chair type massager.
It relates to the machine.

[0002]

2. Description of the Related Art Conventionally, a chair-type massage machine has been developed in which the height at which the user performs a massage operation can be automatically changed according to the sitting height level of the user (patented). No. 2511451). In this massage machine, the operation part for performing fir, rubbing, etc., called a "treatment element," is temporarily raised to the upper limit height before starting the massage operation, and then lowered to the user's shoulder. The abutment position is determined based on the detection signal from the pressure sensor built into the massager at this time, and this abutment height position is set as the origin of a series of subsequent massage operations. The programmed massage operation is sequentially executed from the origin (that is, the shoulder position) upward or downward.

That is, although the sitting height level of a human has a large difference due to differences in height and the like, the distance from the shoulder level to the neck level and the distance from the hip level to each other are different when the provisional decree and the sitting height level are different. However, with the recognition that there is a substantially constant ratio relationship, the expected distance from the origin to the neck position and the expected distance from the origin to the shoulder or waist position are standardized numerical data, that is, the vertical direction. It was stored as the required number of points to occupy in the row of a plurality of points set in the above, and this was shifted in the point row as needed after setting the origin.

[0004]

However, as a result of actually using this massage machine by a large number of persons having various height differences, it is possible to obtain a uniformly and sufficiently satisfactory therapeutic effect by the massage. Was not. It is not clear in the publication disclosing the above-mentioned conventional massage machine that there is no explanation of the grounds for determining the numerical data, but according to the applicant's inference, this numerical data is from the origin (shoulder position) to the neck position. It is thought that this is because the vague expected distance to the area around the shoulders or the waist or the like, and the technical idea of merely allowing the treatment element to reach "around that".

The human body shape is not so simple and clear as based on the above recognition, and even if the vague numerical control as described above is performed, it does not make much sense. That, in order to exert a therapeutic effect by massage, it is necessary to appropriately stimulate Tsu Bo, vague numerical control is not sufficient. The present invention was made in view of the above circumstances, and an object thereof is to provide a chair type massage machine capable of obtaining a therapy effect by stimulating the appropriate pot.

[0006]

In order to achieve the above object, the present invention takes the following technical means. That is,
The chair-type massage machine according to Ming
(This motion is not only for fir balls, but also for shiatsu,
(Including moving parts for performing taki, rubbing, etc.)
Backrest part, and the movement element along the height direction of the backrest part
Chair-type massage machine having a moving drive unit for moving
In the course selection section to select the treatment course
Acupoints for each treatment course selected by the selection unit
Based on the information, move the actuator to the position of the pot
Characterized by surge.

For example, as a treatment course, a fatigue recovery course
, Gastrointestinal improvement course, bowel movement improvement course, liver disorder improvement course
, Low back pain improvement course, neuralgia improvement course,
Select one of the courses in the course selection section. Recovery from fatigue
When a course is selected, information on the acupoints for recovery from fatigue is displayed.
Based on this, the acupoints are massaged. This makes the appropriate
The acupoint is stimulated and the therapeutic effect of massage is demonstrated
It Further, the position control unit moves the operator to the pot position.
After that, make a slight movement in the height direction of the backrest from the point position.
It is characterized by being movable. In this case,
Even if there is a slight difference from the point position of the
BO position can be stimulated.

Further, the range of the fine movement is about 40 m.
About m is preferable. In addition, when the present invention is viewed from another viewpoint,
In the combined chair-type massaging machine, the backrest portion includes a moving element that performs a massage operation, and a movement driving portion that moves the moving element along the height direction of the backrest portion. A position control unit for stopping the motion element at a specific position on the back side of the user, which is the pot position, is provided for the section. The specific position in this case is the position of each acupoint and is expressed with the shoulder position as the reference, but the reference position is not limited to the shoulder position, and may be the back side of the body such as the waist position. As long as it is any part. However, the specific position information for determining the specific position, the height measurement targeting a large number of people in advance, and the distance measurement between the predetermined parts of the body (for example, the size between the shoulder and waist), Is the average position data obtained by aggregating for each predetermined height range and calculating the average value.

That is, this specific position information is based on statistics. When the user selects and inputs his / her own height into the position control unit during the starting operation, such position information is matched by the position control unit with the height from the stored plurality of specific position information. Items are selected and read out. Then, the position control unit controls the movement amount of the movement element by the movement drive unit based on the read specific position information. That is, the invention here is
Not only when there is a difference in sitting height level, there are various things such as differences in age and sex, or characteristics of body shape, etc., and when considering combinations of these,
It is based on the knowledge that it is impossible to control the robot so that it can be adapted to all people with only uniform numerical data that have been vaguely determined. Data is collected from many humans with different sexes, body types, etc.

Particularly, here , the principle of massaging acupuncture points is emphasized in order to relieve the stiffness of the mind and body, and attention is paid to the fact that the acupuncture points for this purpose are lined up on both sides along the spine, and the position control section is considered. The specific position information to be stored in is indicated as a plurality of acupoint positions arranged along the spine. Therefore, when data is collected from a large number of humans as described above, position data of a predetermined acupoint is collected. Data collection for this acupoint position may be measured depending on medical data, but instructions, tactile sensations, and in some cases data collection targets based on empirical rules of acupressure and acupuncturists, or those involved in the massage industry. It is preferable to take into consideration the impressions of the people.

[0011] In particular, if you are an expert such as an acupressure person, the purpose you want for massage (for example, recovery of general muscle fatigue, improvement of built-in function, improvement of bowel movement, improvement of low back pain, etc.), height and sex Also, since he is well aware of subtle differences in acupoint positions due to combinations with age, body type, medical history, etc., a very good massage effect can be obtained. Note that it is not necessary to set all the specific position information to the pot position, for example, set specific position information indicating the “origin” at a predetermined position near the shoulder, and set the other specific position information as the pot position based on the origin. The other specific position information may be measured in a distance.

After the actuator is moved to the position controller based on the predetermined specific position information, it can be finely moved from the specific position in the height direction of the backrest (that is, it is operated by an artificial switch operation. If there is a slight difference between the average acupoint position and the actual acupoint position, it is possible to operate the child by an arbitrary amount or to have a configuration that allows massage while finely moving the actuator within a certain range from a specific position). Can also handle. In addition, when the user changes the posture, there is a slight shift in the stiffness position, there is a wound on the body part corresponding to the specific position information, or when it is tailored to personal preference, be sure You can massage the acupoint position.

When the position control section is provided with a position display section for informing the user of the current position of the motion element, the user can grasp the progress of the massage and when the stiffness is particularly strong. You can manage your own health, etc., and it will be convenient when you want to massage the area. In this case, the position display unit may be a voice, a sound (buzzer), light, or the like. One <br/> hand, the operation control method of the chair slave type massage machine, the collected positional data in a plurality of pot aligned along the spine from a number of people different height, they every predetermined height range After dividing, the average position data is calculated for each, and the average position data is stored in advance as the specific position information.

Then, when the height is input during the starting operation, the height range classification suitable for this height is selected,
A plurality of specific position information written in this, that is,
A part or the whole is read from the acupoint position, and the movement drive unit is operated while maintaining a predetermined time for performing a massage operation for each read specific position information. is there. Therefore, a highly effective massage is performed on the whole body or partial area of the user under automatic driving.

The time interval for moving the movement element (massage drive unit) between the specific position information, the moving order thereof, and the combination of the specific position information itself can be appropriately changed according to the purpose of the massage. is there.

[0016]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. The chair type massage machine 1 according to the present invention will be described with reference to the external view illustrated in FIG. 1. As its basic configuration, a chair body 2 and an operator provided on a backrest portion 3 of the chair body 2 are provided. It has a massage drive unit 5 for massaging 4 and a movement drive unit 6 for moving the massage drive unit 5 along the height direction of the backrest 3.

Although not shown in the figure, a position control section as a circuit for controlling the operating state of the movement drive section 6 is provided for the movement drive section 6. The control by this position control unit is
The massage drive unit 5 is stopped in order to match the motion element 4 to a specific position on the back side of the user, for example, the acupoint position shown in FIG. 2 (which is the “acupuncture point” in terms of Oriental medicine). It is something to do. The device configuration of the massage machine 1 according to the present invention is not particularly limited as long as it has the above basic configuration. Therefore, in the following, Japanese Patent Application No. 8-185258
The case of applying the one having substantially the same configuration as that described in the application specification related to the issue will be described.

In the chair body 2 of the illustrated example, the seat surface portion 8 is supported by the left and right legs 10 integrally provided with the armrest portions 9, and the footrest 11 is provided at the front portion of the seat surface portion 8. It has been set. The footrest 11 and the backrest portion 3 are for reclining,
The angle with respect to the seat surface portion 8 can be changed by an electric mechanism or a fluid pressure drive mechanism (not shown) as appropriate.
The seat surface portion 8 itself is also capable of a certain amount of back-and-forth movement, vertical movement, and the like as the angles of the footrest 11 and the backrest portion 3 are changed.

The movement drive unit 6 causes the feed screw 14 provided along the height direction of the backrest 3 to be screwed with the massage drive unit 5, and the feed screw 14 is connected to an electric motor or the like. The massage drive unit 5 can be moved to the user's neck side or hip side by rotating the forward / backward rotation with the driving unit 15 provided. It should be noted that, in addition to this, as the movement drive unit 6, it is also possible to adopt a winding drive mechanism, a meshing structure of a rack and a pinion, a linear movement means using a fluid pressure cylinder or the like.

The massage drive unit 5 is shown in FIGS.
And a base frame 17 that can be moved directly by the movement drive unit 6, as shown in FIG.
A rocking plate 19 which is provided via a pair of left and right side link mechanisms 18 and whose upper and lower ends can be rocked back and forth, and a rocking plate interposed between the base frame 17 and the rocking plate 19. The moving plate driving part 21, the upper and lower link mechanisms 23 and 24 provided for the swing plate 19, and the respective link mechanisms 23 and 24,
24, and a link driving part 25 provided separately.

The above-mentioned operating element 4 is provided for each link mechanism 23, 24. Each of these operating elements 4 is formed as a roller rotatable about the horizontal axis, but the operating element 4 held by the upper link mechanism 23 is larger than the operating element 4 held by the lower link mechanism 24. The diameter is large, the height of the backrest portion 3 protruding is large, and the left-right spacing is wide. Since the upper and lower link mechanisms 23 and 24 have substantially the same structure, only the upper link mechanism 23 will be described with reference to FIGS. 3 and 4.

The upper link mechanism 23 includes operator support frames 27 and 28 provided so as to be capable of crossing and swinging with respect to a vertical axis 26 provided on both the left and right sides, and a link for limiting the swinging range thereof. 29 and 30. The link driving part 25 described above is provided between each of the operator support frames 27 and 28 and the swing plate 19. An air cell having a bellows pump structure or a balloon structure is used for the link driving part 25. That is, when pressurized air is supplied to the link driving portion 25, axial expansion occurs, and the operator 4 projects obliquely forward with the vertical axis 26 as the center, and conversely, the link driving portion 25 is pressurized. Exhaust or suction of air causes axial contraction, and the operator 4 returns to the original state.

Therefore, by synchronously controlling the supply and discharge of the pressurized air to the left and right link driving parts 25, the left and right actuators 4 repeat mutual proximity and mutual separation, which causes the fir motion. It will happen. On the other hand, four oscillating plate drive parts 21 provided between the base frame 17 and the oscillating plate 19 are used at substantially the same position as the link drive part 25, as is clear from FIGS. 4 and 5. And
Of these four, the link driving part 2 of the upper link mechanism 23
The left and right two corresponding to No. 5, that is, the upper row, and the left and right two corresponding to the link driving part 25 of the lower link mechanism 24, that is, the lower row, are synchronized or exchanged with each other to supply the pressurized air. I am supposed to get rid of it.

Therefore, the pressurized air is supplied to and discharged from the oscillating plate motive parts 21 in the upper row and the oscillating plate motive parts 21 in the lower row in an alternating manner, whereby the oscillating plate 19 is oscillated. As a result, the upper and lower motion elements 4 perform an up-and-down alternating movement. This causes the acupressure action and the tapping action. Further, by supplying and exhausting the pressurized air to and from the oscillating plate driving portions 21 in the upper row and the lower row at the same time, all the operating elements 4 start to move in and out synchronously. As a result, a finger-pressure operation or a tapping operation having a slightly different pattern from those described above are caused.

In the massage machine 1 having such a device structure, the position control section for operating the movement drive section 6 is applied to the user leaning against the backrest section 3 as described above. , To the specific position on its back
Can be matched. Therefore, the position control unit provides specific position information (this is dimensional information on the device side) for instructing the movement drive unit 6 to operate in accordance with these specific positions (this is dimensional information on the user side). It is stored in advance. The specific position information is obtained as follows when the specific position is an acupoint position arranged along the spine as shown in FIG.

That is, first, for a large number of people with different heights, the height measurement and the sitting height (Y1 dimension) measurement, and each acupoint position when the shoulder side measurement point P used in this sitting height measurement is the origin. Distance measurement (Y2 corresponding to lungs, Y3 corresponding to septum, Y4 corresponding to spleen, etc.). In this embodiment, the distance below Y2 is
The measurement is performed partially with reference to the positions adjacent to the upper side, but the present invention is not limited to this, and the distance may always be measured from the point P.

Further, the respective dimensions shown by Y2 to Y7 are only given as an example to a typical acupoint position, and the acupoint positions not included in these (shoulder central 兪, 厥 神 兪, 蜪, ...
Etc.) may be used as a target, or, although not shown, there are more acupuncture points on the back side of a human, and the distance may be measured for them as necessary. Next, the individual data thus collected are divided into predetermined height ranges, and an average value is calculated for each division. Then, the average position data thus obtained is used as the specific position information.

Therefore, in the present embodiment, the specific position information has a height range of approximately 3 cm to 5 c as shown in Table 1.
When divided into A to F at intervals of about m, they are obtained over Y1, Y2, ... Y7 for each division. In addition, Table 1 shows the results of data collection for each of the categories A to F with 100 or more data collection subjects.

[0029]

[Table 1]

In the position control section which stores such specific position information, when the user sits on the chair body 2 and performs a starting operation and inputs his / her height, the position control section is selected from the above A to F categories. A section suitable for the height is selected, and the specific position information of Y1, Y2, ... Y7 written in this section is read out. Then, the position control unit sequentially instructs the movement drive unit 6 to perform a predetermined operation based on the read specific position information. For example, when the entered height matches the A category,
The position control section selects Y1 from the seat surface portion 8 of the chair body 2 by selecting the A section (that is, 53.4c).
It is determined that there is a point P (origin) at a position separated by m).

Then, a distance Y2 (that is, 6.) which is necessary for the upper or lower operator 4 of the massage drive unit 5 to move from the point P to a required pot position (for example, lung ax). 4 cm) and its moving direction are instructed to the movement driving unit 6. Of course, at this stage, it is necessary to take into consideration where the operator 4 is stopped,
Necessary operations for alignment are performed. At this time,
In order to detect the current position and movement distance of the movement element 4, a rotation speed detector (not shown) such as a rotary encoder or a rotary potentiometer is provided in the rotating portion of the feed screw 14 or the driving portion 15 of the movement driving unit 6. In advance, a method of calculating the moving distance of the massage drive unit 5 from the rotation speed may be adopted.

Instead of this, a rail member (see reference numeral 32 in FIG. 4) for guiding the movement of the massage drive unit 5 and a distance detector (not shown) such as a linear potentiometer are provided along the feed screw 14. , Massage drive 5
A detector (not shown) may be provided on the side and the moving distance thereof may be directly measured. After moving the motion element 4 to the target position as described above, the massage drive unit 5 performs a massage operation for a predetermined time, so that the lungs are massaged.

It is preferable that the position control section is configured such that the movement driving section 6 can be finely moved in the height direction after the operator 4 reaches the target position. That is, it is preferable that the operator be operated by an arbitrary amount by an artificial switch operation, or massage can be performed while moving the operator within a certain range from a specific position. The range of this tremor is
It is appropriate to set it to about 40 mm. In this way, even if there is a slight difference between the average position of the acupuncture points and the actual acupoint position, the acupoint position can be surely stimulated. In addition, when the user changes his posture after setting the P point (origin), there is a slight shift in the stiffness position, there is a wound in the body part corresponding to the specific position information, or personal preference is given. It is possible to respond flexibly even when matching.

Next, the position control unit determines the distance Y3 (that is, 9.3 cm) required for the operator 4 to move from the current position to the next required pot position (for example, a distance). The movement direction is instructed to the movement drive unit 6. After that, the massage drive unit 5 performs a massage operation for a predetermined time, so that the massage is performed on the partition. As is clear from the above description, the operation time of the massage drive unit 5 is taken into consideration for the time interval at which the position control unit instructs the movement drive unit 6 to operate from one specific position information to the next specific position information. It has become a thing.

By repeating such an operation, a highly effective massage is performed on the whole body or partial area of the user under automatic driving.

[0036]

EXAMPLES Next, an example of a specific massage program will be described. 6 to 8 are flowcharts showing a procedure until the position control unit selects and executes a predetermined massage program at the same time when the user starts the position control unit. 3 shows a controller 40 for the user to perform a starting operation and the like.
This controller 40 is provided with a lid 41 that can be opened and closed on the operation surface. As shown in FIG. 9A, with the lid 41 open, various manual operations according to the user's preference are possible. And the lid 4 as shown in FIG. 9 (b).
With 1 closed, the automatic treatment course can be selected from a plurality of ways.

Below, the state where the lid 41 is closed will be mainly described. On the front surface side of the lid 41, a course selection portion 42 is provided in the lower half portion thereof, and the display surface portion 44 can be seen through the transparent cover portion 43 in the upper half portion. As the execution pattern of the automatic treatment course, the course selection unit 42 can select a total of 6 patterns of standard courses by independently using the number keys 1 to 6 arranged in an outer ring shape, and at the center of these number keys. A total of 6 can be obtained by combining the shortcut mode key and each number key.
You can select a shortened course of the pattern.

In the standard course, the acupressure at each acupoint position is repeated three times while the massage drive unit 5 is reciprocated twice by the movement drive unit 6, and the seat surface portion 8 and the footrest 11 are appropriately provided. The mechanism allows finger pressure to be applied to the outside of the lower limbs. The time required is about 15
Minutes. On the other hand, in the shortened course, the massage drive unit 5 is reciprocated by the movement drive unit 6 only once, and the finger pressure at each acupoint position is only once, and the finger pressure for the lower limbs is omitted. However, the content of the massage operation itself is
It is basically the same as the one with the same number in the standard course. It takes about 5 minutes.

The outline of each course is as follows. Course 1 is a fatigue recovery course, in which the middle pressure, the heart pressure, and the liver pressure are massaged in this order by the normal pressure method, and then the kidney pressure is massaged by the gentle pressure method. The course 2 is a gastrointestinal improvement course, in which the urine and the stomach are massaged by the gentle pressure method after the massage of the incubus and the stomach is performed by the normal pressure method. Course 3 is a bowel movement improving course, in which Sankoyu is massaged by the normal pressure method, and then the large intestine and the small intestine are massaged by the gentle pressure method.

Course 4 is a liver injury improvement course,
After massaging the Yin-Yu and Sant-Yu by the normal pressure method, massage the Liver-Yoru and Sanjyo-Yo by the gentle pressure method. The course 5 is a low back pain improvement course in which the spleen is massaged by the normal pressure method, and then the kidney, the large intestine, and the small intestine are massaged by the gentle pressure method.
The course 6 is a neuralgia improvement course. For example, in the case of sciatica, the large intestine is massaged by the normal pressure method, the small intestine is massaged by the gentle pressure method, and then the legs and the like are pressed. In assisting neuralgia, a gentle pressure method is applied to the heart and a normal pressure method is applied to the heart, and then the legs are acupressure.

On the other hand, on the display surface section 44, a course display section 45 for displaying the fact that the automatic treatment course is being selected, the number of the selected course, etc., and the current position of the operator 4 are the light emitting points. The position display section 46 for displaying, the elapsed time display section 47 for displaying the remaining operation time, the strength display section 48 for displaying the strength of the massage force, and the like are provided. Here, the position display unit 46 displays (notifies) the position to the user by voice, sound (buzzer), light, or the like.
Good as a thing. In addition, in the controller 40, the lid 4
When 1 is opened, the course display section 45 is turned off, and in place of this, the display of "favorite manual course" is turned on. In addition, the course selection unit 42 is also substantially in a non-functioning state.

Then, an ascending step button 49 and a descending step button 50 are provided on the part hidden by the lid 41 (the part corresponding to the course selecting part 42). The up-and-down step button 49 and the down-and-step step button 50 can operate the movement drive unit 6 only while the push operation is performed, whereby the operator 4 is stepped by an arbitrary amount. You can do it. This controller 40 has a lid 4
A power-on unit 52 is provided on the upper side of 1, and a height selection unit 53 is provided adjacent to the power-on unit 52. This height selection unit 53
It has a height setting button 54 and a plurality of display LEDs 55, and the display LED 55 can light up and display the height range selected by operating the height setting button 54.

Here, the height is selected from three ranges, and one of the ranges is that the height of the user is 165c.
When the height is less than m (corresponding to A, B and C classifications in Table 1), the next one is that the user's height exceeds 165 cm and 1
When the height is 75 cm or less (corresponding to the categories D and E in Table 1), the other one is when the user's height exceeds 175 cm and is 190 cm or less (corresponds to the category F in Table 1). ). By dividing the range as described above, it is possible to substantially correspond to the individual difference in the acupoint position, and if necessary, the acupoint position can be surely stimulated by the fine movement of the motion element 4.

The display LED 55 is provided corresponding to these ranges, and the LED 55 corresponding to the range selected by the height setting button 54 is turned on. At the lower end of the controller 40, a strength selection section 57 for selecting the strength of the massage force and a reclining adjustment section 58 of the chair body 2 are provided. Next, this controller 4
A procedure for setting an automatic treatment course using 0 will be described based on FIGS. 6 to 8. The controller 40 sequentially guides the input procedure by lighting the display section so that even a person unfamiliar with the operation can easily operate the controller 40. Therefore, when the power is first turned on, the user is first prompted to select the height (step 101).

Therefore, the user has steps 102 to 104.
As shown in, the height setting button 54 of the height selection unit 53 is pressed an appropriate number of times to select a range suitable for one's own height. As a result, the predetermined specific position information is read (see steps 105, 108 and 107). In addition, statistically 1
The height setting button 54 is not operated in order to take into consideration the fact that there are many people who have a height of more than 65 cm and 175 cm or less, and to allow a person who is not accustomed to the operation to press the height setting button 54. In this case, it is programmed that the predetermined specific position information is read automatically assuming that the area of more than 165 cm and less than 175 cm is selected.

After this, the strength of the massage force is set according to the preference of the user (see step 109 to step 115). If you do not make this setting, the medium level is automatically selected. Next, the controller 40 displays a message requesting the selection of the course and prompts the user to perform a required operation (step 1).
16). To select a shortened course, first press the shortcut mode key, and then press the desired number key from 1 to 6 (see steps 118 to 124). Instead of pressing the mode key, the desired number key in 1 to 6 may be pressed as it is (see steps 131 to 136).

Therefore, the predetermined operation program is read and executed. The subsequent execution of the program is performed along each of the above-mentioned courses, and detailed description thereof will be omitted here. By the way, the present invention is not limited to the above embodiment. For example, the detailed structure of the massage drive unit 5, the shape and number of the movement elements 4, the detailed structure of the movement drive unit 6, and the like can be changed as appropriate. That is, as for the massage driving unit 5 and the like, not only the one using an air cell but also a mechanically operating structure may be used. Further, the chair-type massage machine according to the present invention includes not only a chair-type massage machine having a chair shape as a whole, but also a machine that can be used while sitting on a chair by being attached to a backrest of the chair.

[0048]

As is apparent from the above description, in the chair type massage machine according to the present invention, the selected treatment course is selected.
The actuator is moved to the position of the point based on each point information.
Since the massage is performed, the acupoints suitable for the purpose of treatment can be stimulated, and the therapeutic effect of the massage can be exerted.
