Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a massager suitable for massaging a portion to be treated of a human body, such as a shoulder.

[0002]

2. Description of the Related Art For example, a chair type massage machine has an air bag (massage element) that expands and contracts due to air supply and exhaust so that a massage unit for massaging a shoulder of a human body can be vertically adjusted. There is one on the backrest. In addition, a so-called massaging ball, which has a roller (massage element) that is driven by the power of an electric motor and is commonly known as a massaging ball, is provided movably on the backrest or the like, and the massaging element is used to detect the shoulder position of the human body. A chair-type or bed-type massage machine that controls the movement of a massage unit based on this detection to massage the upper half of the human body is also known. In these massage machines, the massager can be adjusted to the shoulder position of the human body by adjusting the movement of the massage unit along the body axis direction of the human body.

In addition to moving the entire massage unit in the body axis direction of the human body in this way, moving the entire massage unit in other directions requires a large-scale mechanism, which is extremely difficult to realize. Is believed to be involved. Therefore, there has not yet been provided a massager in which the position of the massager can be adjusted by moving the entire massage unit in the thickness direction of the human body supported by the backrest or the like.

The shoulders of the human body are not only different in height position but also in shape and thickness due to individual differences, and the upper body may be bent in the thickness direction. Naturally, there are individual differences in the position of the acupuncture points that are effective for shoulder massage.

However, since the conventional massager cannot adjust the position for moving the massaging element in the thickness direction of the human body as described above, the position of the acupuncture points such as the shoulders of various users and the desired position can be adjusted. It is difficult to massage with a massager at a desired position. Therefore, the massage desired by the user may not be performed in some cases, and improvement thereof is desired.

[0006]

5 is a device frame 21, a massage unit 22
And a height position adjuster, for example, one or more, more specifically, two air bags 23 and a return spring 24.

The device frame 21 is fixed to the upper part of the back frame 4a. The device frame 21 has groove-shaped rails 25 extending on both sides thereof in the longitudinal direction of the backrest 4, in other words, in the body axis direction of the seated person. The pair of rails 25 are provided so that the openings extending in the longitudinal direction face each other.

The massage unit 22 includes a unit base 26, a shoulder massage portion 27, and a position adjusting body 28 for changing the position of the massage portion 27 in the thickness direction of the seated person. The unit base 26 has a front wall 26a and an end wall 26b located on the front end side of the backrest 4 and connected to the front wall 26a at a substantially right angle. The front wall 26a is formed of a flat plate having a width slightly shorter than the distance between the pair of rails 25. Unit base 2
A plurality of rollers 29 are rotatably attached to the left and right sides of 6, respectively.

As shown in FIGS. 3 and 7, the unit base 26 is assembled with the apparatus frame 21 by inserting its rollers 29 into the rails 25. Therefore, the unit base 26 of the massage unit 22 is provided so as to be movable along the rail 25 in the body axis direction of the seated person.
As shown in FIGS. 4 to 6 and the like, the end wall 26 in the combined state is shown.
b extends so as to cross the rail 25.

The shoulder massaging portion 27 is disposed in front of the front wall 26a, and includes a massaging element support plate, for example, one rotating plate 31, and a pair of the massaging part 27 mounted side by side in the width direction of the chair body 2. Shoulder massager, for example, an air bag 32. As shown in FIG. 3, a mounting portion 33 is integrally provided on a part of the outer periphery of the air bag 32, and a mounting member 34 such as a screw screwed into the rotating plate 31 through the mounting portion 33 causes the air The bag 32 is fixed in a cantilevered state. In this case, the pair of air bags 32 are attached to the rotating plate 31 with the attachment portions 33 thereof being close to each other.

Both air bags 32 inflated and deflated by air supply and exhaust
The expansion / contraction part of the shape is circular in a plan view, and contracts so as to become thin in the exhausted state (represented by the right side part in FIG. 7) and expands in a substantially hemispherical shape in the supplied state (FIG. 7).
Represented by the left side of. ) Is formed. Moreover, the top portion 32a of the expanded / contracted portion is eccentric from the center of the expanded / contracted portion toward the mounting portion 33, whereby the expanded / contracted portion expands from the contracted state while gradually moving the top portion 32a toward the mounting portion 33. It is like this. The movement locus of the top portion 32a in this case is indicated by an arrow on the left side portion of FIG.
Therefore, when the two airbags 32 are inflated synchronously, their tops 32a are brought closer to each other.

The rotating plate 31 functions as a wall that prevents the airbag 32 from expanding toward its back. One side of the rotating plate 31, for example, the lower side, has a pair of hinges 35.
It is attached to the front wall 26a via. for that reason,
The shoulder massaging portion 27 is provided so as to be rotatable in the vertical direction with the hinge shaft of the hinges 35 as a fulcrum. A coiled spring 35a is attached to the hinge 35. The spring 35a urges the rotating plate 31 in the direction in which the free end side thereof approaches the front wall 26a.

The position adjusting body 28 is formed of, for example, an air bag that expands and contracts due to air supply and exhaust. At least a part of the adjusting body 28 is arranged between the front wall 26a and the rotating plate 31, and, for example, the lower side thereof is fixed to the front wall 26a. The back surface of the rotating plate 31 is pressed against the position adjusting body 28 arranged in this way by the biasing force of the spring 35a. The front wall 26a functions as a wall that prevents the position adjusting body 28 from expanding toward its back. Therefore, the shoulder massaging portion 27 tilts forward with the hinge 35 as a fulcrum as the position adjusting body 28 expands, and the position adjusting body 2
8 is pushed back by the force of the spring 35a so as to stand up as 8 is contracted.

The air bag 23 is superposed on each other, and the end wall 21a of the apparatus frame 21 and the unit base 26 are stacked.
It is sandwiched between the end wall 26b and the end wall 26b. The return spring 24 has its both ends connected to the end walls 21a and 26b, respectively, and always urges the unit base 26 toward the end wall 21a. Therefore, as the airbag 23 expands, the massage unit 22 is pushed and moved along the rail 25 against the biasing force of the return spring 24, and as the airbag 23 contracts, the massage unit 22 is massaged by the biasing force of the return spring 24. The unit 22 is moved.

The construction of the pair of waist massage devices 16 is similar to that of the shoulder massage portion 27. That is, as shown in FIG. 2 (A), the waist massage section 16 is
The back base cushion 4b has a support plate 41 fixed to the front surface with an adhesive or the like, and a pair of waist massaging elements, for example, an air bag 42, which are mounted side by side in the width direction of the chair body 2 on this surface. The structure of the air bag 42 is the same as that of the shoulder air bag 32, and the air bag 42 is attached by a mounting tool 44 such as a screw that is screwed into the support plate 41 through a mounting part 43 projecting on a part of the outer periphery thereof. 42 is fixed in a cantilevered state. In this case, the pair of airbags 42 are attached to the support plate 41 with the attachment portions 43 of the airbags 42 approaching each other.

The back airbag 17 is formed in a vertically long shape, and only the fixed end portion (upper end portion in FIG. 2) having the air supply / exhaust ports is fixed to the front surface of the back base cushion 4b with an adhesive or the like. There is. The other end of the air bag 17 is simply a free end overlapping the front surface of the back base cushion 4b. Therefore, the air bag 17, which is inflated and deflated by air supply and exhaust, is inflated so that its free end side is closer to the fixed end, and an upward force is applied to the seated person during this inflation.

The back cushion 4c and the back cover 4d have the degree of freedom that they can be easily deformed following the vertical movement and forward tilting motion of the massage unit 22 and the inflating motion of the air bags 42 and 17.

A drive device 50 is arranged below the seat portion 3. As shown in FIG. 9, this device 50 includes, for example, an air pump 52 that moves a diaphragm by electromagnetic drive to perform a pump operation, and an air pump 52 such as a rotary valve connected to an outlet of the pump 52 through an air tube 53. The distribution device 54, the solenoid valve 55 connected to the first tube 53a branched from the air tube 53, the solenoid valve 56 connected to the second tube 53b branched from the air tube 53, and the control device 51. I have it.

One end of an air tube 57 is connected to the first distribution port of the air distribution device 54, and the other end of the tube 57 is one end of the three-pronged air supply / exhaust port body 58 shown in FIG. 2 (A). Connected to the department. The other two ends of the air supply / exhaust port body 58 are connected to the waist airbag 42, respectively. The second distribution port of the air distribution device 54 communicates with the back airbag 17 via the air tube 59. One end of an air tube 60 is connected to the third distribution port of the air distribution device 54,
The other end of the tube 60 is connected to one end of the three-pronged air supply / exhaust port body 61 shown in FIG. The other two ends of the air supply / exhaust body 61 are respectively the airbag 32 for shoulders.
Is in communication with.

The rotary valve forming the air distributor 54 has an exhaust port (not shown), and when the air supply to one distribution port is selected, the other distribution port communicates with the exhaust port. Further, the distribution ports are sequentially selected as the rotor (not shown) is rotated by the step motor.

Two height adjusting air bags 23 are connected to the electromagnetic valve 55 via an air tube 62, respectively, and a position adjusting body 28 is connected to the electromagnetic valve 56 via an air tube 63. . These solenoid valves 55, 56
Each has an exhaust port, and an air supply position, a closed position, and an exhaust position can be selected.

The solenoid valve 55 allows air to be supplied to the air bag 23 in the intake position, closes the flow path in the closed position to maintain the expanded state of the air bag 23, and in the exhaust position, air discharged from the air bag 23. Can be discharged to the outside from the exhaust port. Similarly, the solenoid valve 56
Air is allowed to be supplied to the position adjusting body 28 at the intake position, the flow path is closed at the closing position to maintain the expanded state of the position adjusting body 28, and the air discharged from the position adjusting body 28 is discharged from the exhaust port at the exhaust position. Can be discharged to. As described above, the solenoid valves 55 and 56 are used as the inflation holding elements of the airbag 23 and the position adjusting body 28 corresponding to the solenoid valves 55 and 56, so that the position adjusting body 28 and the solenoid valve 56 are used in the thickness direction of the seated person. The position adjusting means for changing the position of 32 is configured.

The control device 51 controls the air pump 52, the air distribution device 54, and the solenoid valves 55 and 56, and is formed of a microcomputer or the like. An operation unit operated by a seated person, for example, a remote controller 71 is connected to the control device 51, and a driving command is given by the controller 71.

As shown in FIG. 8, the remote controller 71 has angle adjusting buttons 72a and 72b for changing the angle of the shoulder massager 27 of the massage unit 22 with respect to the human shoulder, and the shoulders, back, or. Point button 73 for selecting any massage position on the waist
, A course button 74 for performing a course operation, a pulse button 75 for supplying air with pulsation to the airbag to be inflated and depressed, and a strength button 76 for changing the degree of massage by changing the degree of inflation of the airbag. And shoulder massage part 2
Height adjustment buttons 77a and 77b for changing the height position of the human body 7 with respect to the shoulder of the human body, a stop button 78 for ending all operations, and the like are provided.

The point button 73, which is reset by pressing the stop button 78, first designates the shoulder portion, the first depression designates the back portion, the second depression designates the waist portion, and the third depression designates the waist portion. The designation of the shoulder portion again by pressing is repeated until it is reset. Also, the course button 7
When pressing 4 to drive a predetermined course,
A massage operation is performed in which the shoulder portion is designated a plurality of times, the back portion is designated, and finally the waist portion is designated a predetermined number of times.

In this way, the point button 73 or the course button 7
When 4 is operated, it is possible to cause the shoulder massage device 15 to perform a massage operation starting a massage operation from the neck and shoulder of the human body. This means that the height of the neck and shoulder and the massage points at the neck and shoulder are adapted to the position in the thickness direction of the human body, as will be described later.
In the massage machine 1 capable of adjusting the position of two dimensions two-dimensionally, the massage is started from the two-dimensional adjustment state by making use of the feature of the two-dimensional adjustment, which is preferable in that the massage can be performed without waste in operation.

When using the massage machine 1 having the above structure, the seated person first adjusts the massage unit 22 to the shoulder of the human body. This adjustment is a height direction adjustment in which the massage unit 22 is moved toward and away from the human body shoulder portion, and a thickness direction adjustment in which the shoulder portion massage portion 27 is rotated and moved in the thickness direction of the human body shoulder portion. It is done with and.

The height direction adjustment is performed by the remote controller 7
The height adjustment buttons 77a and 77b of No. 1 are adjusted.
While the pressing operation of the height adjustment button 77a for instructing the direction in which the shoulder massage unit 22 approaches the human shoulder is continued, the operation of the air pump 52 is continued,
Since the solenoid valve 55 maintains the air supply position, air supply to the height adjusting airbag 23 is continued, and this air supply is stopped by releasing the pressing operation of the height adjusting button 77a. At the same time, the operation of the air pump 52 is stopped, the electromagnetic valve 57 maintains the closed position, and the air bag 23 is held in the inflated state.

While the shoulder massage unit 22 continues to press the height adjustment button 77b for instructing the direction of moving away from the human shoulder, the solenoid valve is stopped while the air pump 52 is stopped. Since 55 is the exhaust position, the air in the height adjusting air bag 23 is exhausted,
This exhaust is stopped by releasing the pressing operation of the height adjustment button 77b. At the same time, the massage unit 2 is pressed by the urging force of the return spring 24 according to the amount of contraction of the airbag 23.
2 is raised.

Therefore, by operating at least one of the height adjusting buttons 77a and 77b to move the massage unit 22 in the direction toward and away from the shoulder of the human body, the feel of the airbag 32 hitting the shoulder of the human body is felt. Based on the above, the massage unit 22 can be arranged at a height position desired by the seated person. FIG. 6 illustrates the inflated state of the air bag 32.

In this state, the thickness direction adjustment is performed next, and this adjustment is performed by the angle adjustment button 72 of the remote controller.
This is done by operating a and 72b. While the operation of pressing the angle adjustment button 72a continues, the air pump 52 continues to operate and the solenoid valve 56 maintains the air supply position. Therefore, air supply to the air bag forming the position adjusting body 28 is performed. The air supply is stopped by releasing the pressing operation of the angle adjustment button 72a. At the same time, the air pump 52
Is stopped, the solenoid valve 56 maintains the closed position, and the position adjusting body 28 is held in the expanded state.

Further, while the operation of pressing the angle adjusting button 72b is continued, the electromagnetic valve 56 is in the exhaust position with the operation of the air pump 52 stopped, so that the position adjusting body 28 for adjusting the thickness direction is formed. The air inside is exhausted, and this exhaust is stopped by releasing the pressing operation of the angle adjustment button 72b. The solenoid valve 56 maintains the closed position, and the position adjusting body 28 is held in the expanded state.

Therefore, the thickness direction adjusting buttons 72a, 72b
By operating at least one of the two to move the airbag 32 of the shoulder massager 27 steplessly in the thickness direction of the backrest 4, in other words, in the thickness direction of the human body,
The air bag 32 can be arranged at an arbitrary position in the thickness direction desired by the seated person, based on the feeling of hitting the top 32a of the air bag 32. As described above, due to the expansion of the position adjusting body 28, the shoulder massaging portion 27 is rotated about the hinge 35 as a fulcrum so as to be tilted forward, and is placed so as to cover the shoulder portion of the human body obliquely from above and rearward. An example is shown in FIG.

In both of the above adjustment states, the solenoid valve 55,
It is held when 56 is in the closed position. As the final stage of this adjustment, the thickness direction adjustment buttons 72a, 72
When the adjustment buttons 72a and 72b are not operated for a predetermined time after the above operation of b, the operation of the air pump 52 is started and the simultaneous air supply / exhaust to the pair of airbags 32 is performed through the air distributor 54. It is repeated more than once, for example, several times. As a result, the pair of airbags 32 are inflated and a massage force is applied to the shoulders of the human body, so that it is possible to experience whether or not the acupressure point by the top portion 32a of the airbag 32 is in a desired position depending on the adjustment states. . If necessary based on this physical feeling, the adjustment operation described above may be repeated and readjustment may be performed so that the desired finger pressure is appropriately performed on the human shoulder.

According to the above procedure, the top 32a of the air bag 32 can be aligned with the massage point of the shoulder of the human body, which differs depending on the thickness and shape of the seated person's shoulder, the bending of the upper body, and the like. After this adjustment, various massages designated by the remote controller 71 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, as described above, the shoulder massager 27 is oblique to the human shoulder. Since the massage is performed in a state in which the massager 32 is arranged so as to cover it from the upper rear, the massage direction of the massager 32 is different from pushing the human body forward in the thickness direction.

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 structure, the air bag 23 is used as an element for moving the massage unit 22 in the height direction, and the air bag is also used as an element for rotating the shoulder massage unit 22. Since the position adjusting body 28 consisting of is used, it can be driven by each of the airbags 17, 32, 42 incorporated in the chair body 2 and the common driving device 50.

In addition, the massage machine 1 having the above-mentioned structure has a shoulder massage part 27 covered by the back cover 4b, so that the chair can be made into a good appearance. In addition, when the shoulder massager 27 is not used, the shoulder massager 27 is standing as shown in FIG. 4, and the position adjusting body 28 made of an air bag and the airbag 3 making a massager are used.
No. 2 is in a contracted state. Therefore, the shoulder massaging portion 27 does not become a hindrance, and the chair can be used like a normal chair with a backrest.

In one embodiment of the above configuration, since the movement of the massage unit 22 can be adjusted, the degree of freedom of adjustment with respect to the human shoulder (treatment area) is greater. However, since the height can be adjusted to some extent even when the shoulder massage portion 27 is rotated in the front direction, in the present invention, it is formed by the air bag 23, the return spring 24, the roller 29, the rail 25, and the like. The height direction adjusting means may be omitted by moving the massage unit 22 in the direction toward and away from the human shoulder.

Further, in the present invention, as the position adjusting body 28,
In addition to using a bellows-like stretchable air bag,
In place of the air bag, an electric motor and a position adjusting body which is reciprocated by the electric motor and has a connecting member whose tip is rotatably connected to the rotating plate 31 and which is mounted on the unit base are provided. Can be used. In any case, this does not mean that the shoulder massaging device 15 as a whole is typified by the one embodiment described above.
Since the shoulder massage portion 27, which is a part of the above, is rotated to adjust the shoulder portion of the human body, it is structurally simple and does not require a large scale.

Further, in the present invention, the rotating plate 24 is provided with
A so-called massaging ball, which is commonly referred to as a massaging ball, may be mounted with a massage mechanism having a roller (massage element) driven by the power of an electric motor.
