2. Description of the Related Art A shoulder massaging device provided on a backrest of a chair-type massaging machine has a left and right shoulder massaging elements provided symmetrically on a common vess, and a pair of them can be moved by moving a common base. The massager can be moved by the same distance at the same time, and the massager can be positioned at the height of the shoulder of the human body sitting on the chair body.

By the way, it is rare that the shoulders of the human body are bilaterally symmetrical, and the thickness of the shoulders is different between the left and right, or the upper half of the human body is bent in the thickness direction or bent sideways. Or it may be twisted. Due to such individual differences, the height positions and front and rear positions of both shoulders of the human body with respect to the backrest when sitting on the chair body are different.

However, as described above, in a conventional chair-type massage machine in which a pair of massaging elements for massaging the left shoulder portion and the right shoulder portion are simultaneously moved by the same distance to adjust the height position, for example, both shoulders of the human body are If the height positions of the parts are different, the height adjustment for substantially aligning the massaging element with respect to one of the shoulders is merely performed. for that reason,
When the upper half of the human body is bent to the side, massage for one shoulder is sufficient and massage for the other shoulder is likely to be insufficient.

Moreover, in the conventional chair type massage machine,
The shoulder massaging device cannot be moved in the thickness direction of the human body sitting on the chair body to adjust the front-back position of the massaging element. Therefore, when the upper half of the human body is bent or twisted in the thickness direction, the massage for the human shoulder away from the backrest tends to be insufficient, and its improvement is desired.

[0006]

The problem to be solved by the present invention is to obtain a chair-type massage machine capable of massaging both shoulders of a human body regardless of the difference in the positions of the shoulders.

[0007]

In order to solve the above-mentioned problems, the invention of claim 1 provides a pair of massaging elements for individually applying massage force from above to both shoulders of a human body sitting on a chair body. Align the massage unit with a pair of front-back position adjusters that individually change the front-back position of the massager so that the massager is placed at the desired position in the front-back direction of the shoulder. It is provided on the back of the chair body.

According to the present invention, the pair of massaging elements for the left shoulder and the right shoulder provided in the massage unit are provided in the front-back direction of both shoulders of the human body by using the pair of front-back position adjusting bodies provided corresponding to the massaging elements. It can be individually moved to a desired position so that the front-back direction positions of the pair of massaging elements are individually adapted to the corresponding both shoulders of the human body.

In order to solve the problem, the invention according to claim 3 provides a pair of massage units equipped with a massager for giving a massage force from above to a shoulder portion of a human body sitting on a chair body. The height position adjusting means for individually changing the height positions of these massage units is provided on the backrest while being provided individually on the backrest of the chair body.

According to the present invention, the height position adjusting means individually moves the left shoulder massage unit and the right shoulder massage unit in the height direction by using the corresponding height position adjusting means. The height position of the massager provided in these units can be individually adapted to the height of the corresponding shoulders of the human body.

While pressing the left shoulder selection button 71L,
While the left shoulder massage unit 22L continues to press the height adjustment button 73a for instructing the direction toward the human shoulder, the air pump 52 is continuously operated and the solenoid valve 55L is in the air supply position. Therefore, the air supply to the height adjusting airbag 23L is continued, and the air supply is stopped by releasing the pressing operation of the height adjusting button 73a. At the same time, the operation of the air pump 52 is stopped, the solenoid valve 55L is in the closed position, and the air bag 23L is held in an inflated state. Similarly, while the right shoulder selection button 71R is being pressed, the air pump 52 is pressed while the height adjustment button 73a for instructing the direction in which the right shoulder massage unit 22R approaches the human shoulder is continuously pressed. Operation is continued and the solenoid valve 55
Since R is the air supply position, air supply to the height adjusting airbag 23R is continued, and this air supply is stopped by releasing the pressing operation of the height adjustment button 73a. At the same time, the operation of the air pump 52 is stopped, and the solenoid valve 55R is in the closed position, so that the air bag 2
3R is held in an expanded state.

While the left shoulder selection button 71L is being pressed, the air pump 52 is pressed while the height adjustment button 73b for instructing the direction in which the shoulder massage unit 22 moves away from the human shoulder is continuously pressed. Since the solenoid valve 55L is in the exhaust position while the operation of is stopped, the air in the height adjusting airbag 23L is exhausted, and this exhaust is stopped by releasing the pressing operation of the height adjusting button 73b. It At the same time, the left shoulder massage unit 22L is urged by the spring 24L according to the amount of contraction of the air bag 23L.

At the same time, the right shoulder massage unit 22R is pulled up by the urging force of the spring 24R according to the amount of contraction of the air bag 23R.

Therefore, by operating the shoulder selection buttons 71L and 71R and the height adjustment buttons 73a and 73b, the left and right shoulder massage units 22L and 22R are individually moved in the directions of approaching and separating from the shoulders of the human body. By doing so, the massage unit 22 is placed at the height position desired by the seated person based on the feel of the airbag 32 hitting the shoulder of the human body.
L and 22R can be arranged. FIG. 6 illustrates a state where the airbag 23L is inflated.

The above-mentioned shoulder alignment in the vertical direction corresponds to the left shoulder massage unit 22L provided corresponding to the left shoulder of the seated person and the right shoulder of the seated person by the operation of the remote controller 70 as described above. And the right shoulder massage unit 22R provided separately. Therefore, even if the height positions of the left shoulder and the right shoulder of the seated person are different, the massage units 22L and 22R can be individually arranged at height positions that match them. Therefore, as the airbag 32 is repeatedly inflated and deflated as described later, a proper massage can be performed on both necks and shoulders of the human body.

Moreover, since the left and right massage units 22L and 22R can be individually adjusted in height as described above, one of the shoulders is strongly massaged and the other is weakly massaged according to the stiffness of the shoulder. It is also possible.

For the above shoulder alignment, for example, an adjustment start button is provided on the remote controller 70, and the button is pressed to operate the pair of left and right massage units 22L and 22R in synchronization with the shoulders of the human body. Alternatively, the required height adjustment of the massage unit on the shoulder side may be performed by the procedure described above.
In this case, it is possible to detect the strength of contact of the air bag 32 of both massage units 22L and 22R to both shoulders, and it is easy to recognize the massage unit on one side that requires height adjustment after that. Can be done easily.

Then, with the shoulder alignment completed, the thickness direction adjustment is performed next. This adjustment is made by the shoulder selection button 7
This is performed by operating the angle adjustment buttons 72a and 72b of the remote controller 70 while pressing 1L or 71R.

While the operation of the air pump 52 is stopped while the operation of the angle adjustment button 72b is continued while the left shoulder selection button 71L is being pressed, the electromagnetic valve 56L is in the exhaust position, so the left shoulder The air in the front-back position adjusting body 28 is exhausted, and the exhaust is stopped by releasing the pressing operation of the angle adjustment button 72b. Along with this, the solenoid valve 5
Since 6L is in the closed position, the front-rear position adjuster 28 for the left shoulder is held in a contracted state or a desired inflated state. Similarly, the angle adjustment button 7 is pressed while the right shoulder selection button 71R is pressed.
While the pressing operation of 2b is continued, the air pump 52
Since the solenoid valve 56R is set to the exhaust position with the operation of stopped, the air in the front-back position adjuster 28 for the right shoulder is exhausted, and this exhaust is stopped by releasing the pressing operation of the angle adjustment button 72b. To be done. Along with this, the solenoid valve 56R
Is in the closed position, the front-back position adjusting body 28 for the right shoulder is held in a contracted state or a desired expanded state.

Therefore, by operating at least one of the thickness direction adjusting buttons 72a and 72b while pressing the shoulder selection button 71L or 71R, the air bag 32 of the pair of left and right shoulder massage portions 27 is moved in the thickness direction of the backrest 4, in other words, in other words. For example, by moving the airbag 32 steplessly in the thickness direction of the human body, the airbag 32 can be arranged at any position in the front-rear direction desired by the seated person based on the feel of the top 32a of the airbag 32 hitting the neck and shoulders. As described above, the front-back position adjusting body 28 is inflated, the shoulder massage portion 27 is rotated about the hinge 35 as a fulcrum so as to tilt forward, and the shoulder portion is arranged so as to cover the shoulder portion of the human body obliquely from above and rearward. Is illustrated in FIG.

The shoulder alignment in the front-rear direction is performed by operating the remote controller 70 as described above, by corresponding to the left shoulder massage unit 22L provided corresponding to the left shoulder of the seated person and the right shoulder of the seated person. And the right shoulder massage unit 22R provided separately. Therefore, even if the seated person's left shoulder and right shoulder have different positions in the front-rear direction with respect to the backrest 4, the airbags 32 of the massage units 22L and 22R can be individually arranged at the front-rear positions that match them. Therefore, as the airbag 32 is repeatedly inflated and deflated as will be described later, a similar massage can be performed on both necks and shoulders of the human body from the upper side without excess or deficiency.

In both of the above adjustment states, the solenoid valve 55 is used.
L, 55R, 56L, 56R are held by being in the closed position. As the final stage of this adjustment, if these adjustment buttons 72a, 72b are not operated for a predetermined time after the above-described operations of the thickness direction adjustment buttons 72a, 72b,
The operation of the air pump 52 is started and the air distribution device 5
Simultaneous air supply / exhaust with respect to the pair of left and right airbags 32 is repeated once or more, for example, several times via the control unit 4. As a result, both air bags 32 are inflated and a massage force is applied to the shoulders of the human body, so that the acupressure points by the tops 32a of the air bags 32 are brought to the desired positions corresponding to the body shape of the seated person depending on the adjustment states. You can experience whether or not you are there. If necessary based on this physical feeling, the adjustment operation may be repeated to readjust the desired acupressure to both shoulders of the human body.

By the above procedure, the top 32a of the air bag 32 can be fitted to the massage points on both shoulders of the human body, which differ depending on the sitting height of the seated person, the thickness and shape of the shoulders, the way the upper body is bent, and the like. After this adjustment, various massages designated by the remote controller 70 can be performed.

When the shoulder massager 27 is operated by this massage, and when the shoulder massager 27 is operated at the final stage of the adjustment, the shoulder massager 27 is used as described above.
Is performed so that it covers the shoulders of the human body obliquely from above and rearward, so the massage direction of the airbag 32 is different from pushing the human body forward in the thickness direction, and the massage is performed from the upper side of the shoulders. To be done.

Specifically, from diagonally above and behind the human shoulder,
A massage is performed diagonally downward and forward, and as shown in the inflated state of the airbag 32 on the left side in FIG. 7, the tops 32a of the pair of airbags 32 are attached to each other from both sides of the neck of the human body. It is possible to acupressure the human shoulder while moving it toward the root. Therefore, the massage for the human neck and shoulder can be satisfactorily performed.

Further, in the massage machine 1 having the above construction, the airbag 23 is used as an element for moving the left and right massage units 22L and 22R independent from each other in the height direction, and the shoulder massage portions of the massage units 22L and 22R are used. The front-back position adjusting body 28 including an air bag is also used as an element for rotating the 27. Therefore, each of the airbags 17 and 3 incorporated in the chair body 2 is
The air bag 2 is driven by the drive device 50 that is common to the air bags
It is possible to drive the 3L and 23R and both front and rear position adjusting bodies 28, and the massaging machine 1 can be made lightweight.

Moreover, since the shoulder massager 27 is covered by the back cover 4b, the massage machine 1 having the above-described structure can be a chair having a good appearance. In addition, when the shoulder massager 27 is not used, the shoulder massager 27 stands up as shown in FIG. 4, and the front-back position adjusting body 28 made of an air bag and the air bag 3 making a massager are used.
No. 2 is in a contracted state. Therefore, the shoulder massage part 27 does not interfere much and can be used like a normal chair with a backrest.

The present invention is not limited to the above embodiment. For example, the height adjusting means is formed by using a mechanical feed mechanism, for example, a feed screw rotated by an electric motor and a nut screwed to the screw and fixed to the massage unit, instead of the airbag. A mechanical feed mechanism or the like can be used. Further, as the massaging element, a massaging element in which an acupressure convex portion made of a relatively hard material is attached to an air bag that repeatedly expands and contracts may be used. Furthermore, it is commonly called a massaging ball and is driven by the power of an electric motor. A massaging mechanism having a roller (massage element) to be operated can be attached to the rotating plate 31 for implementation. Further, in the present invention, a bellows-like expandable and contractible air bag can be used as the front-back position adjusting body 28, and instead of the air bag, an electric motor and a reciprocating motion of the electric motor cause the tip to rotate to the rotating plate 31. It is possible to use a front-back position adjusting body or the like that is formed with a connecting member that is movably connected and that is mounted on the unit base 26.

In the invention of claim 1, the massage unit does not necessarily have to be divided into the left shoulder and the right shoulder. In this case, the unit base in the above-described embodiment can be implemented as a common component, and an air bag or the like for adjusting the height position for moving the single base in the vertical direction can be shared. Moreover, in the first aspect of the invention, the height position adjusting means may be omitted and the massage unit may be immovably arranged at a predetermined height position of the backrest.
