BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chair-type massaging machine in which a shoulder massaging device for massaging the shoulder part of a human body is attached to a backrest of a chair body.

[0002]

2. Description of the Related Art Some chair-type massage machines are provided with a shoulder massager whose height is adjustable on the backrest. In this massage machine, a pair of massaging elements included in the shoulder massaging device can be simultaneously moved by the same distance, and the massaging elements can be positioned at the height of the shoulder of the human body sitting on the chair body.

Since the strength of massage to the human shoulder in this type of massage machine depends only on the shoulder alignment of the massager, the massage feeling may not be sufficient depending on the adjustment of the shoulder alignment. In this case, it is troublesome to stop the massage and readjust the height position, and improvement thereof is desired.

Further, the chair type massage machine provided on the backrest so that the height of the shoulder massaging device cannot be adjusted cannot cope with a feeling of massaging the shoulder of the human body. Therefore, they are forced to use it without feeling the massage.

[0005]

The problem to be solved by the present invention is to provide a chair-type massager capable of strongly massaging the shoulder part of a human body as necessary, regardless of whether or not the shoulder position of the massager for shoulder can be aligned. To get the opportunity.

[0006]

In order to solve the above problems, according to the present invention, a backrest of a chair body is provided with a shoulder massager for giving a downward massage force to a shoulder of a seated person sitting on the chair body. In the chair type massage machine
An air bag for pushing up a human body, which is inflatable so as to sandwich an upper half of the body between a seated person's shoulder and hips with a shoulder massager, is provided in the seat of the chair body.

In the present invention, the shoulder massaging element provided on the backrest may be provided so that the height position can be adjusted, or can be provided so that such height position adjustment cannot be performed. Also, an air bag that expands and contracts due to air supply and exhaust can be suitably used for the shoulder massager,
Without being limited to this, for example, a so-called kneading ball made of rollers that is operated by the power of an electric motor can be used as a shoulder massaging element.

In the present invention, when the airbag for pushing up the human body in the seat portion is inflated, the upper half of the body of the seated person can be pushed up accordingly and the shoulder position of the human body can be raised. Therefore, the massage action that the shoulder massager gives downward to the human shoulder can be strengthened in the pushed-up state.

The gas spring 10 extends when the back is released from the backrest 4 under the operation of the lever 13, so that the backrest 4 can be raised by rotating the backrest 4 counterclockwise in FIG.

As shown in FIGS. 1 to 3, a shoulder massaging device 15 is attached to the upper portion of the backrest 4.
A pair of lumbar massaging devices 16 are attached to the lower part of the backrest 4, and a back massaging element such as an air bag 17 is disposed between the devices 15 and 16 in the widthwise central portion of the backrest 4. ing.

A shoulder massaging device 15 for massaging the shoulder or neck shoulder of a human body seated on the chair body 2 is a device frame 21 fixed to the upper part of the back frame 4a.
In addition, the massage unit 22 is provided immovably so that the height position cannot be adjusted, for example. As shown in FIGS. 4 and 5, the massage unit 22 includes a unit base 24, a shoulder massage section 25, and a massage section 25.
And a front and rear position adjusting body 26 for changing the position of the position in the thickness direction of the seated person.

The unit base 24 formed of a flat plate is
Both ends are supported by being connected to a base support plate 4f which is fixed on both sides to the upper end of the back frame 4a. The shoulder massaging portion 25 includes a massaging body support plate disposed in front of the unit base 24, for example, a horizontally long rotating plate 28, and a pair of shoulders mounted on the surface of the plate 28 side by side in the width direction of the chair body 2. It has a massager 29.

As shown in FIG. 6, the massager 29 is formed by combining an air bag 31 and a pressing member 32. Specifically, the air bag 31 is a blow-molded product of a low-hardness synthetic resin material that can be easily expanded and contracted, specifically, a polyethylene resin. The air bag 31 that expands and contracts due to air supply and exhaust has a substantially quadrangular shape, and a pair of mounting portions 33 and an air supply and exhaust port 34 arranged between them are integrally provided on one side edge thereof.

Locking projections 35 are integrally formed at the centers of the two edges of the air bag 31 which are parallel to each other in the longitudinal direction. The locking protrusions 35 protruding in opposite directions are
It has a shape in which the head of the tip is wider than the root, for example, a T-shape. Each of the mounting portion 33 and the locking convex portion 35 is a non-inflatable portion, and is formed to have a larger wall thickness than a bag portion that expands and contracts so as not to be easily deformed.

The pressing member 32 is an integrally molded product made of a material having a hardness higher than that of the air bag 31, for example, a hard synthetic resin, specifically a polypropylene resin. The pressing member 32 is formed, for example, by integrally extending mounting arms 37 on both sides in the radial direction of a hard pressing protrusion 36 having a substantially hemispherical hollow shape. The tip of the mounting arm 37 is provided with a locking projection 35 of the airbag 31.
For example, a mounting end portion 37a that is bent in an L-shape is formed so as to wrap around and cover the edge having. Each of the mounting arms 37 is provided with a flexible deformable portion 38 located between the mounting end portion 37 a and the pressing convex portion 36. The flexible deformable portion 38 is a thin self-hinge formed by forming a groove across the mounting arm 37 in the width direction thereof. Therefore, the hard pressing member 32 can be freely bent and deformed around the two flexible deformation portions 38.

At the mounting ends 37a of the two mounting arms 37,
An L-shaped bent locking hole 39 is formed. Locking hole 3
The width of 9 is larger than the width of the base of the locking projection 35, and
It is smaller than the width of the head of the locking projection 35. Furthermore, the locking hole 3
The diagonal length of 9 is larger than the width of the head portion of the locking projection 35.

Therefore, the locking projection 3 of the air bag 31
By twisting 5 through the locking hole 39, as shown in FIG.
As shown in (A), the locking projections 35 can be hooked in the locking holes 39, and the pressing member 32 can be mounted on the surface of the air bag 31 so as to overlap. In this way, the massager 29 can be assembled without using an adhesive, and in the assembled state, the pressing convex portion 36 of the pressing member 32 is arranged at the substantially central portion of the air bag 31. Locking hole 39 and locking projection 35
Even if the pressing member 32 is deformed by following the expansion of the air bag 31 via the flexible deforming portion 38, the catching with and does not come off.

As shown in FIG. 4, the pair of massaging elements 29 having the above structure are rotated by a mounting member 40 such as a screw screwed into the rotating plate 28 through the mounting portions 33 which are brought close to each other and overlap each other. It is fixed to the front surface of the plate 28 in a cantilevered state. The rotating plate 28 functions as a wall that prevents the air bag 31 of the massaging element 29 from expanding toward its back.

As shown in FIGS. 4 and 5, the lower portion of the rotating plate 28 is attached to the unit base 24 via a pair of hinges 23. Therefore, the shoulder massage part 25 is provided so as to be rotatable in the vertical direction with the hinge shaft of the hinges 23 as a fulcrum. A coil-shaped spring 23a (see FIG. 4) is attached to the hinge 23. The spring 23a biases the rotating plate 28 in a direction in which the free end side of the rotating plate 28 approaches the unit base 24.

The front-rear position adjuster 26 is formed of, for example, an air bag that expands and contracts due to air supply and exhaust. This adjustment body 2
6 is arranged between the unit base 24 and the rotating plate 28, and the lower side thereof is fixed to the unit base 24, for example. The back surface of the rotating plate 28 is pressed by the biasing force of the spring 23a against the front-rear position adjusting body 26 arranged in this manner. The unit base 24 is a front-back position adjusting body 26.
Acts as a wall that prevents it from expanding toward its back. Therefore, the shoulder massager 25 is tilted forward with the hinge 23 as a fulcrum as the front-back position adjusting body 26 is inflated and stands up as the front-back position adjusting body 26 is contracted by the force of the spring 23a. Pushed back. In the present embodiment, the front-back position adjusting body 26 may be a bellows-shaped expandable air bag, and instead of the air bag, an electric motor and a reciprocating motion of the electric motor may be used to move the tip of the rotary plate 28. It is also possible to use a front-back position adjuster or the like that is formed with a connecting member that is rotatably connected to and is mounted on the unit base.

Since the shoulder massaging device 15 having the above-mentioned structure has the hard pressing projection 36, it is excellent in that a desired portion of the human shoulder can be locally and strongly pressed. A massager that does not have such a hard pressing protrusion 36, for example, a massager formed by an air bag that expands and contracts due to air supply and exhaust may be used.

As shown in FIG. 2, the pair of lumbar massaging devices 16 has a support plate 41 fixed to the front surface of the back base cushion 4b with an adhesive, and the width of the chair body 2 on the surface of the support plate 41. It has a pair of waist massaging bodies, for example, an air bag 42, which are mounted side by side in the direction. The air bag 42 that expands and contracts due to air supply and exhaust expands into a hemispherical shape due to air supply. The air bag 42 is fixed to the support plate 41 in a cantilever state by a mounting tool 44 such as a screw that is screwed into the support plate 41 through a mounting portion 43 that is provided on a part of the outer periphery of the air bag 42. In this case, the pair of air bags 42 are attached to the respective support plates 41 with the attachment portions 43 of the air bags 42 brought close to each other.

The back airbag 17 which is inflated and deflated by air supply / exhaust is formed in a vertically long shape, and only the fixed end (upper end in FIG. 2) having the air supply / exhaust port is bonded to the front surface of the back base cushion 4b. It is stopped with a drug. The other end of the airbag 17 is simply a free end overlapping the front surface of the back base cushion 4b. This air bag 1
7 expands so that its free end side is closer to the fixed end.

The front cushion 4c and the front cover 4
d is the vertical movement and forward tilting motion of the massage unit 22,
In addition, it has a degree of freedom that allows it to be easily deformed following the inflation operation of the air bags 17, 42.

A drive device 50 is arranged below the seat portion 3. This device 50 has a controller 5 as shown in FIG.
1, an air pump 52 that moves a diaphragm by electromagnetic drive to perform a pump operation, an air distributor 54 such as a rotary valve connected to an outlet of the pump 52 via an air tube 53, and an air tube 5
Solenoid valve 55 connected to the first branch tube 53a branched from No. 3 and the second valve branched from the air tube 53
And a solenoid valve 56 connected to the branch tube 53b.

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 this tube 57 is connected to one end of the three-pronged air supply / exhaust port body 58 shown in FIG. Has been done. 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, and the other end of the tube 60 is connected to one end of a three-pronged air supply / exhaust port body (not shown). The other two ends of the air supply / exhaust port body (not shown) are connected to the air supply / exhaust ports 34 of the pair of air bags 31 included in the massager 29.

The rotary valve forming the air distribution device 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.

The solenoid valve 55 is communicated with the front-back position adjusting body 26 via an air tube 61. This solenoid valve 5
5 has an exhaust port, and can select an air supply position, a closed position, and an exhaust position. The solenoid valve 55 permits air supply to the airbag forming the front-rear position adjusting body 26 in the intake position, closes the flow path in the closed position to maintain the inflated state of the air bag for the front-rear position adjusting body 26, and in the exhaust position. The air flowing out from the front-back position adjusting body 26 air bag can be discharged to the outside through the exhaust port. Since the electromagnetic valve 55 is used as an expansion holding element of the front-back position adjusting body 26 in this manner, the front-back position adjusting body 26 and the electromagnetic valve 55 change the front-back position of the shoulder massager 25 in the thickness direction of the seated person. It constitutes a front-back position adjusting means.

The solenoid valve 56 communicates with the human body pushing air bag 14 through an air tube 62. The solenoid valve 56 has an exhaust port, and can select an air supply position, a closed position, or an exhaust position. The solenoid valve 56 allows air to be supplied to the air bag 14 in the intake position, closes the flow path in the closed position to maintain the expanded state of the air bag 14, and in the exhaust position, discharges the air flowing out from the air bag 14 to the exhaust port. It can be discharged to the outside. Thus, the solenoid valve 56
Is used as an inflation holding element of the air bag 14 for pushing up the human body, so the air bag 14 and the solenoid valve 56 are
Constitute a shoulder position adjusting means for changing the shoulder position of the seated person.

The control device 51 controls the air pump 52, the air distribution device 54, and the electromagnetic 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 70 (see FIGS. 1 to 3) is connected to the control device 51, and a driving command is given by the controller 70.

The remote controller 70 selects a pair of angle adjustment buttons for changing the angle of the shoulder massager 25 of the massage unit 22 with respect to the human body shoulder, and a massage position of either the shoulder, the back or the waist. A point button for doing, a course button for driving the course, a strength button for changing the shoulder position of the seated person to change the strength of the massage, and a strength release button for canceling the setting by this strength button. , A stop button for ending all the operations (all not shown).

When using the massage machine 1 having the above-mentioned configuration, the seated person first performs shoulder position alignment by adjusting the front-rear position of the massage unit 22 to the shoulder of the human body and adjusting the upper half of the body.

The front and rear position adjustment is performed by the remote controller 7
By operating the angle adjustment button 0, the shoulder massager 25
Is performed by rotating. Specifically, while the operation of pressing the angle adjusting button for forward leaning continues, the operation of the air pump 52 is continued and the solenoid valve 55 maintains the air supply position. Therefore, the air supply to the airbag forming the front-back position adjusting body 26 is continued, and the air supply is stopped by releasing the pressing operation of the angle adjusting button for forward leaning.
Simultaneously with the release of the pressing, the operation of the air pump 52 is stopped, the electromagnetic valve 55 is in the closed position and is maintained in that state, and the front-rear position adjusting body 26 is held in the expanded state.

Further, while the operation of pressing the return angle adjusting button is continued, the solenoid valve 55 is set to the exhaust position while the operation of the air pump 52 is stopped. for that reason,
The air in the air bag forming the front-rear position adjuster 26 is exhausted, and the exhaust is stopped by releasing the pressing operation of the return angle adjusting button. Simultaneously with the release of the pressing force, the solenoid valve 55 enters the closed position and maintains that state.

Therefore, by operating at least one of the pair of angle adjusting buttons of the remote controller 70, the massaging element 29 of the shoulder massaging portion 25 is moved in the thickness direction of the backrest 4, in other words, the thickness direction of the human body (front-back direction). By rotating the massager 29 steplessly with displacement, the massager 29 is placed at any position in the front-rear direction desired by the seated person based on the feel of the hard pressing protrusion 36 of the massager 29 hitting the neck and shoulders. it can. As described above, due to the expansion of the front-back position adjuster 26, the shoulder massager 25 is moved to the hinge 23.
Is pivoted so as to fall forward about the fulcrum, and is arranged so as to cover the shoulder portion of the human body obliquely from the upper rear side. The above-described front-rear position adjustment state is maintained when the solenoid valve 55 is in the closed position. The above-described front-back position adjustment can also be performed by holding the airbag 31 of the massager 29 in an inflated state.

After that, the upper body is pushed up and adjusted to change the shoulder position of the seated person. This adjustment is performed by operating the strength button of the remote controller 70. Specifically, while the pressing operation of the strength button is continued, the operation of the air pump 52 is continued and the solenoid valve 56 maintains the air supply position. Therefore, the air supply to the air bag 14 for pushing up the human body in the seat portion 3 is continued, and the air supply is stopped by releasing the pressing operation of the strength button.
Simultaneously with the release of the pressure, the operation of the air pump 52 is stopped, the electromagnetic valve 56 is set to the closed position and the state is maintained, and the air bag 14 is held in the inflated state.

Further, while the operation of pressing the strength release button of the remote controller 70 continues, the solenoid valve 56 is in the exhaust position while the operation of the air pump 52 is stopped. As a result, the airbag 1 receiving the weight
The air in 4 is exhausted, and this exhaust is stopped by releasing the pressing operation of the strength release button. Simultaneously with the release of the pressing force, the solenoid valve 56 is placed in the closed position and the state is maintained.

Therefore, by operating at least one of the strength button and the strength release button of the remote controller 70 to adjust the inflated state of the airbag 14 arranged under the seated person's hips, The seated person can be pushed up and held according to the amount of expansion. Further, when the pressing operation of the strength release button is continued for a predetermined time or longer, the airbag 14 is pressed.
Is contracted.

The contracted state of the air bag 14 is shown in FIG.
As shown in FIG. 3, the inflated and held state of the airbag 14 is shown in FIG.
It is shown in (B). The inflation of the air bag 14 pushes up the upper half of the seated person. Therefore, the shoulder portion of the shoulder massager 29 surely contacts the shoulder portion of the human body, and the upper body portion between the seated person's shoulder portion and the hip portion, in other words, the upper body portion excluding the head portion, is in contact with the airbag 14 and the shoulder. It comes to be sandwiched between the massage child 29.

Then, as a final step of the above shoulder position adjustment, a test operation is performed according to a program previously set in the control device 51. That is, the operation of the air pump 52 is started, and the simultaneous air supply / exhaust for the pair of air bags 31 of the shoulder massager 29 is repeated once or more, for example, several times via the air distributor 54. Thereby, the air bag 31 of the pair of massaging elements 29
Expands and gives a massage force to the human shoulder, so that it is possible to experience whether the locally limited acupressure point on the shoulder of the human body due to the pressing convex portion 36 is at a desired position depending on the adjustment state. it can. FIG. 5B illustrates a state where the airbag 31 is inflated by this test operation. Then, if necessary based on the bodily sensation, the degree of inflation of the airbag 14 may be readjusted so that the desired acupressure is properly performed on the human shoulder.

According to the above procedure, the pressing convex portion 36 of the massager 29 can be aligned with the massage point of the human neck shoulder portion which varies depending on the thickness of the shoulder of the seated person. After this adjustment, various massages specified by the remote controller 70 can be performed.

The operation of the shoulder massager 25 in this massage and the shoulder massager 25 at the final stage of the adjustment
As described above, since the shoulder massager 25 is arranged so as to cover the shoulders of the human body obliquely from above and above, as described above, the pressing convex portion 3 of the massager 29 is provided.
The massage direction of 6 is different from simply pushing the human body to the front side, and the pressing convex portion 36 massages the human body shoulder portion from the upper side to the lower side. Specifically, the massage is performed by acupressure of the human shoulder from diagonally upper and rearward of the human shoulder to diagonally lower front.

As described above, this massage is performed with the airbag 14 in the lower hip position inflated and held, and the upper half of the body of the seated person is pushed up and adjusted as described above. Can massage. The feeling of massage in this case can be achieved by adjusting the degree of swelling of the air bag 14 for pushing up the human body, so that the massage unit 22 can be easily realized without the need to move the massage unit 22 up and down along the backrest 4. it can. Moreover, since the operation of inflating the airbag 14 is simple and this inflation adjustment can be performed independently of the operation of the massage unit 22, the shoulder position is adjusted as necessary during the massage to adjust the human shoulder. The intensity of massage to the part can be changed arbitrarily. Of course, when the airbag 14 is deflated and massaged, the shoulder of the human body can be weakened.

Not limited to this embodiment, when a height position adjusting mechanism for moving the massage unit 22 in the vertical direction along the backrest 4 is provided and implemented, this height position adjusting mechanism cannot be used for adjustment. Even if there is not, by inflating the airbag 14 and pushing up the upper body of the human body, the shoulder position is arranged in the adjustment range by the height position adjusting mechanism, and the shoulder position is adjusted by the vertical movement of the massage unit 22. It is possible to do.

Further, in the massage for the shoulder of the human body, the pair of air bags 31 fixed to the rotating plate 28 in a cantilever manner are inflated while approaching the center of the backrest 4 in the width direction. Along with this, since the pair of pressing protrusions 36 are moved toward the root of the human body neck from both sides of the human body shoulder portion, the human body shoulder portion can be acupressured, so that the human body neck shoulder portion can be satisfactorily massaged.

In the above massage, the state where the airbag 31 of the shoulder massager 25 is inflated is shown in FIG. 5 (B).
Is shown in. In the present embodiment, the aforesaid finger pressure is performed by the hard pressing member 32 according to the expansion and contraction of the air bag 31, but in this case, the hard pressing member 32 is easily bent around the plurality of flexible deformable portions 38. be able to. Therefore, the pressing member 32 does not hinder the inflation of the airbag 31 even though the pressing member 32 is superposed on the surface of the airbag 31, and the airbag 3
The hard pressing member 32 can be pushed toward the shoulder of the human body following the expansion of No. 1.

Further, the air bag 14 for pushing up the human body of the massage machine 1 can be operated even if the stop button of the remote controller 70 is operated, unless the strength release button of the remote controller 70 is continuously pressed for a predetermined time or longer. Since the push-up adjustment state of the upper half of the human body can be maintained, when the same person uses it, there is no trouble of performing the push-up adjustment each time a massage is started.

The shoulder massaging device 15 follows the instructions from the remote controller 70 and the front-back position adjusting body 2
It is also possible to repeatedly inflate and use the air bag 31 of the shoulder massager 25 while keeping 6 in a contracted state. In this case, the state in which the air bag 31 is contracted is shown in FIG. In this usage pattern, the hard pressing convex portion 36 of the pressing member 32 against the human shoulder is weakened, and the massage force can be weakened accordingly.

In the massage machine 1 having the above-mentioned structure, the front-back position adjusting body 26 composed of an air bag is used as an element for rotating the shoulder massage unit 22, and the element for operating the shoulder massage section 25 is expanded and contracted. Since the air bag 31 is used, these can be driven by the common driving device 50 together with the human body pushing air bag 14 incorporated in the chair body 2 and the other air bags 17, 32, 42.

Moreover, since the massager 1 having the above-mentioned structure has both the air bag 14 for pushing up the human body and the shoulder massager 25 covered, it can be a chair with a good appearance. Moreover, when the shoulder massager 25 is not used,
As shown in FIG. 5 (A), the front-back position adjusting body 26 including an air bag and the air bag 31 of the massage body 29 are both in a contracted state, and the shoulder massage portion 25
Is stored in the apparatus frame 21 in a standing posture so as not to get in the way. Therefore, it can be used like a normal chair with a backrest.

FIG. 8 shows a second embodiment of the present invention. Since the second embodiment is basically the same as the first embodiment, the same components as those in the first embodiment will be designated by the same reference numerals and description thereof will be omitted, and the configuration different from the first embodiment will be described below. To do.

In the second embodiment, the air distribution device 5
4 has an air tube 6 connected to the third distribution port
