Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a massage body which is operated by air pressure and massages a portion to be treated of a human body, for example, a shoulder portion, by repeatedly pressing, and a massage machine such as a chair type having the massage body. .

[0002]

2. Description of the Related Art Among massage bodies which are installed in chair-type or bed-type massage machines and which are operated by air pressure,
2. Description of the Related Art There is one that can locally press the treated portion of the human body. As this type of massage body, an air bag that expands and contracts due to air supply and exhaust, and a rotating plate that is provided with a hard hemispherical pressing convex portion on the surface and that is rotated by being pressed by the expansion of the air bag Alternatively, there is known an air bag itself which is inflated and deflated by air supply and exhaust, and integrally has a pressing convex portion located at the top of the inflation.

In the former example, a structure for forming the rotating plate and its rotation fulcrum is required, and in some cases, a spring or the like for causing the rotating plate to follow the contraction operation of the airbag is also required. Sometimes. Therefore, the structure is complicated and the cost is high.

The latter example is superior to the former massage body in that the structure is simple and the cost is low. However, since it is integrally formed, it is difficult to form only the pressing convex portion hard while maintaining the inflation and contraction performance of the airbag. Especially in the case of blow molding. Therefore, although the pressing can be locally limited, the pressing convex portion is liable to be insufficient in hardness and the massage feeling is weak.

It is considered that this lack of hardness can be improved by adhering a pressing convex portion made of a hard material other than the air bag to the surface of the air bag. However, as can be understood from the fact that polyethylene resin, which is a general material for air bags, is used as a container for storing an adhesive, it has poor adhesiveness to a pressing protrusion made of a hard material. Therefore, it was found as a result of an experiment by the present inventor that the pressing convex portion is easily separated from the air bag as the air bag expands. Therefore, it is desired to provide a massage body which is excellent in durability and does not suffer from such a situation.

[0006]

SUMMARY OF THE INVENTION The problem to be solved by the present invention is a simple structure, but it is suitable for locally limiting and pressing the treated part of the human body, and has excellent durability. To obtain a massage body and a massage machine equipped with this massage body.

[0007]

In order to solve the above-mentioned problems, the present invention comprises a pressing member formed of a material harder than the air bag, which is superposed on the surface of the air bag which expands and contracts due to air supply and exhaust. The pressing member is provided with a pressing convex portion that projects in the inflating direction of the airbag and a flexible deforming portion that deforms following the expansion and contraction of the airbag.

In the present invention, the pressing member may be harder than the air bag, and may be made of the same material as the air bag or a material different from the air bag. Further, the massage body of the present invention can be used by being fixedly arranged at a predetermined position of a massage machine body of a chair type massage machine or a bed type massage machine, and can be attached to a massage unit movable with respect to the massage machine body. Can be used. Further, in the present invention, in order to arrange the pressing member on the airbag, the peripheral edge of the airbag and the end portion of the pressing member are integrated by connecting them with an appropriate configuration, or It is possible to adopt a configuration in which the peripheral edge and the end portion of the pressing member are integrally fastened to the support plate or the like of the massage body by screws and the like.

In the present invention, the number of parts constituting the massage body is small. Moreover, even though the pressing member is hard, when the airbag is inflated, the pressing member does not easily deform at its flexible deformation portion and hinders the inflation of the airbag. The pressing member can be easily followed. Therefore, it is possible to locally limit and press the treated portion of the human body with the pressing convex portion of the pressing member that has sufficient hardness.

The reclining lever 1 shown in FIG.
The backrest 4 can be retracted while the gas spring 10 is contracted by operating 3 to apply weight to the backrest 4 as shown in FIG.
It can be tilted by rotating the pivot 9 around the middle clock. Since the gas spring 10 extends by releasing the back from the backrest 4 under the operation of the lever 13, the backrest 4 can be raised by rotating counterclockwise around the pivot 9 in FIG. 2 (B). .

As shown in FIGS. 1 and 2, a massage device such as a shoulder massage device 15 is provided on the upper portion of the backrest 4.
Is installed. 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 sitting on the chair body 2 is a device frame 21 fixed to the upper part of the back frame 4a.
The massage unit 22 is, for example, immovably provided. As shown in FIGS. 3 to 5, the massage unit 22
The unit includes a unit base 24, a shoulder massager 25, and a front-back position adjuster 26 for changing the position of the massager 25 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 fixed to both sides at the upper end of the back frame 4a. The shoulder massaging part 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 shoulder parts mounted on the surface of the plate 28 side by side in the width direction of the chair body 2. And a massage body 29.

As shown in FIGS. 6 and 7, the massage body 2
9 is formed by combining the air bag 31 and the 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 rectangular shape,
A pair of mounting portions 33 and an air supply / exhaust port 34 arranged between them are integrally provided on one side edge of the mounting portion 33.

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
The shape is such that the head portion at the tip end is wider than the root portion, for example, T-shape, but this may be L-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 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, the mounting end portion 37 is bent in an L shape (which may be U-shaped) so as to wrap around and cover the edge having the edge.
a. 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 deformation portion 38 is attached to the mounting arm 3
7 is a thin self-hinge formed by providing a groove transverse to the width direction. 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 of the locking projection 36.

Therefore, the locking projection 3 of the air bag 31
By twisting 5 through the locking hole 39, the locking projection 35 is hooked on the locking hole 39 as shown in FIGS. 6 and 7 (A), and the pressing member 32 is attached to the surface of the air bag 31. It can be mounted in layers. In this way, the massage body 29 can be assembled without using an adhesive, and in the assembled state, the pressing convex portion 36 of the pressing member 32 has the air bag 3
1 is arranged in the substantially central portion. When the locking hole 39 and the locking convex portion 35 are caught, the pressing member 32 is flexibly deformed.
Even if the airbag 31 is deformed to follow the inflation of the airbag 31, it will not come off.

As shown in FIG. 3, the pair of massage bodies 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 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 airbag 31 of the massage body 29 from expanding toward its back.

As shown in FIGS. 4 and 5, one side portion, for example, the lower side portion of the rotating plate 28 is attached to the unit base 24 via a pair of hinges 23. Therefore, the shoulder massage portion 2 is configured with the hinge axis of these hinges 23 as a fulcrum.
Reference numeral 5 is provided so as to be rotatable in the vertical direction. Hinge 23
A coil-shaped spring 23a (see FIG. 3) is attached to the. 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.

As shown in FIG. 2 (A), the back massager 16 has a back base cushion 4b.
It has a support plate 41 secured to the front surface thereof with an adhesive or the like, and a pair of waist massaging bodies such as an air bag 42 mounted on the surface of the plate 41 side by side in the width direction of the chair body 2. 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 airbags 42 are attached to the respective support plates 41 with the attachment portions 43 of the airbags 42 brought close to each other.

The back airbag 17 which is inflated and deflated by air supply and exhaust is formed in a vertically long shape, and only the fixed end portion (upper end portion in FIG. 2) having the air supply and exhaust ports 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 the degree of freedom that it can be easily deformed following the inflating operation of the air bags 42, 17.

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 5 connected to tube 53a branched from 3
5 and.

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 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 massage body 29.

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.

The solenoid valve 55 is communicated with the front-rear 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 thus used as an expansion holding element of the front-back position adjusting body 26, the front-back position adjusting body 26 and the electromagnetic valve 55 change the position of the shoulder massager 25 in the thickness direction of the seated person before and after the change. It constitutes a position adjusting means.

The controller 51 controls the air pump 52, the air distributor 54, and the electromagnetic valve 55, and is formed by a microcomputer or the like. An operation unit operated by a seated person, for example, a remote controller 70 (see FIGS. 1 and 2) 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 adjusting buttons for changing the angle of the shoulder massaging section 25 of the massage unit 22 with respect to the human shoulder and one of the shoulder, back and waist massage positions. Point button to perform a course operation, a course button to perform a course operation, a pulse button to supply air with pulsation to an inflating and deflating air bag, and a strength to change the strength of massage by changing the degree of inflation of the air bag. A button and a stop button for ending all operations (none of them are shown).

When using the massage machine 1 having the above-described structure, the seated person first adjusts the front-rear position of the massage unit 22 so as to fit the shoulder portion of the human body. This adjustment is performed by rotating the shoulder massager 25 by operating the angle adjusting button of the remote controller 70.

That is, while the operation of pushing 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 pressure, the operation of the air pump 52 is stopped, the electromagnetic valve 55 maintains the closed position, 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 electromagnetic valve 55 is set to the exhaust position with the operation of the air pump 52 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 pressure, the solenoid valve 55 maintains the closed position.

Therefore, by operating at least one of the pair of angle adjusting buttons of the remote controller 70, the massage body 29 of the shoulder massage section 25 is displaced in the thickness direction of the backrest 4, in other words, in the thickness direction of the human body. By rotating the massage body 29 steplessly, the massage body 29 can be arranged at any position in the front-rear direction desired by the seated person based on the feel of the hard pressing projection 36 of the massage body 29 hitting the neck and shoulders. As described above, due to the expansion of the front-back position adjusting body 26, the shoulder massage portion 25 is rotated about the hinge 23 as a fulcrum so as to tilt forward, and is disposed so as to cover the shoulder portion of the human body obliquely from the upper rear side.

The above adjustment state is maintained by the solenoid valve 55 being in the closed position. As a final stage of this adjustment, a test run is performed according to a program previously set in the control device 51. That is, the air pump 52
The operation is started and the air supply / exhaust for the pair of airbags 31 of the massage body 29 is performed once or more, for example, several times repeatedly through the air distributor 54. As a result, the air bags 31 of the pair of massage bodies 29 are inflated to give a massage force to the shoulders of the human body. You can experience whether it is in the desired position. A state where the airbag 31 is inflated by this test operation is illustrated in FIGS. 5 (A) and 5 (B). And, if it is necessary based on the experience,
It suffices to repeat the above-described adjustment operation and readjust so that the desired acupressure is properly performed on the human shoulder.

According to the above procedure, the pressing convex portion 36 of the massage body 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 designated by the remote controller 70 can be performed.

When the shoulder massager 25 is operated by this massage, and when the shoulder massager 25 is operated at the final stage of the adjustment, the shoulder massager 25 is used as described above.
Is performed in a state in which it is disposed so as to cover the shoulder of the human body obliquely from above and above, the massage direction of the pressing convex portion 36 is different from simply pressing the human body forward. Specifically, a massage is performed by acupressure on the human body shoulder from the diagonally upper rear side to the diagonally lower front side. Moreover,
In this case, the pair of airbags 31, which are fixed to the rotating plate 28 in a cantilevered state, inflate while approaching the center of the backrest 4 in the width direction, so that the pair of pressing protrusions 36 are provided from both sides of the human body shoulder neck. It is possible to acupressure the shoulder of the human body while moving them toward the base of the neck. Therefore, the massage for the human neck and shoulder can be satisfactorily performed.

In the above massage, the state where the airbag 31 of the shoulder massager 25 is contracted is shown in FIG. 5 (A).
The state in which the airbag 31 is inflated is shown in FIG.
It is shown in (B). According to the expansion and contraction of the air bag 31, the above-mentioned acupressure by the hard pressing member 32 is performed. In this case, the hard pressing member 32 can be easily deformed around the plurality of flexible deformation portions 38. Therefore, even though the pressing member 32 is superposed on the surface of the air bag 31, the pressing member 32 does not hinder the inflation of the air bag 31, and the hard pressing member follows the inflation of the air bag 31. 32 can be extruded toward the shoulder of the human body.

As a result, the pressing convex portion 36 of the hard pressing member 32 is applied with local and limited acupressure in accordance with the size of the convex portion 36 on the shoulder portion of the human body, thereby providing a point massage. You can In addition, the protruding direction of the pressing convex portion 36 of the pressing member 32 and the airbag 3
Since the movement direction of the pressing convex portion 36 coincides with the movement of the top portion of the inflating air bag 31, the displacement of the pressing convex portion 36 is large. Therefore, a more effective point massage can be performed.

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 inflated state of the air bag 31 is shown by a chain double-dashed line in FIG. In this usage pattern, the pressing protrusion 3
6, the hard pressing projection 3 of the pressing member 32 against the human shoulder
The hit of 6 becomes weak, and the massage power can be weakened accordingly.

In the pair of shoulder massage parts 25 which operate as described above, the inflating and depressing air bag 31 and the hard pressing member 32 capable of following the inflating and depressing are connected without the need for adhesion. Therefore, since there is no target portion where peeling occurs regardless of the repeated expansion and contraction of the air bag 31, the durability is superior to the case where the shoulder massage portion 25 is formed using an adhesive. In addition, the air bag 31 and the pressing member 32 are connected to each other by the locking protrusion 35 and the locking hole 39.
Because it was realized by catching with the massage part 2 without any special tools or connecting parts
5 can be assembled.

In the massage machine 1 having the above-mentioned structure, the front-back position adjusting body 26 including 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 also expanded and contracted. Since the air bag 31 is used, these can be driven by the common driving device 50 with the air bags 17, 32, 42 incorporated in the chair body 2.

Moreover, since the shoulder massager 25 is covered with the back cover 4b, the massage machine 1 having the above-described structure can be a chair with a good appearance. Moreover, when the shoulder massager 25 is not used, as shown in FIG. 4, the front and rear position adjuster 26 and the airbag 31 of the massager 29 are both in a contracted state, and the shoulder massager 25 is , 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.

In the above embodiment, a bellows-like expandable and retractable air bag can be used as the front-back position adjusting body 26, and instead of the air bag, an electric motor and a reciprocating motion of the air motor cause the tip to rotate. It is possible to use a front-back position adjusting body or the like that is formed to have a connecting member that is rotatably connected to the moving plate 28 and that is mounted on the unit base.

Further, the constitution of the shoulder massager 25 of the present invention can be applied to a waist massager or the like.
