Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a massage machine having a chair, a treatment means, and a moving means for moving the treatment means, and more particularly to a structure for performing acupressure massage at a predetermined treatment position with a predetermined pressure. It is about.

[0002]

2. Description of the Related Art There have been provided various types of massage machines which can massage around the shoulders by treatment means. And this kind of massage machine has a function of massaging, tapping, rolling massage operation and the like.
When a rubbing and tapping massage operation is performed, the periphery of the shoulder can be pressed from the head toward the buttocks by a predetermined pressing amount.

A conventional massage machine of this type is disclosed in Japanese Patent Application Laid-Open No. 1-236053 filed earlier by the present applicant, and has a structure as shown in FIGS. The following massages, beatings and rolling massages are performed.

In the massaging massage, when the main shaft 1 is rotated by the motor, the inner ring 2 that rotates together with the main shaft 1 is eccentric and inclined with respect to the inside of the main shaft 1, so that the inner ring 2 rotates freely. The treatment element 5 attached via the arm 4 to the outer ring 3 which is freely attached,
Since the movement of the arm 4 is restricted by the connecting link 8, the movement of drawing the three-dimensional trajectory with the rotation of the main shaft 1, that is, the vertical direction, the axial direction of the main shaft 1, and the movement from the main shaft 1. A motion of changing the position in the protruding direction is performed to give a so-called “bend massage” massage to the back of the user.

On the other hand, when the rotating shaft 12 is rotated instead of the main shaft 1, the crankshaft 12 which is an eccentric shaft of the rotating shaft 12 is rotated.
In this case, since the respective arms 4 are connected to the first and second arms a and 12b through the connection links 8, the crankshafts 12 and 12b
Is moved by the eccentric rotation of the arm 4 to move the arm 4 connected by the ball joint 44. At this time, the movement of the arm 4 is stopped.
The treatment element 5 at the tip of the arm 4 becomes a linear reciprocating movement in a substantially vertical direction as viewed from the front, depending on the position of the inner ring 2, and performs a tapping massage, depending on the position of the inner ring 2. Will be. The eccentric direction of both crankshafts 12a and 12b of the rotary shaft 12 as the eccentric member 7 is 18
Since the angle is reversed by 0 °, the beating massage operation is alternately performed in both treatment elements 5 and 5.

Next, when the pinion 17 is rotated by the motor, the main body of the massage machine moves up and down the backrest 84 of the chair, which is a treatment table, along the rail 90 due to the engagement between the rack 91 and the pinion 17. Therefore, the position of the treatment element 5 can be changed up and down. Also, at this time, since the roller-shaped treatment element 5 rolls along the back of the human body, a rolling massage can be obtained in which the treatment element 5 faces the back of the human body. The mechanism for changing the amount of protrusion by expanding and contracting in a substantially vertical direction will be described as follows. When the feed screw 25 is rotated by the motor, and the rotary shaft 12 is rotated around the auxiliary shaft 13 via the link 16 and the rotary plate 15, the arm 4 and the outer ring 3
, Whereby the treatment element 5 changes the amount of projection of the backrest 84 surface in the substantially vertical direction. That is, the treatment element 5 moves so as to expand and contract in a direction substantially perpendicular to the surface of the backrest 84, and the amount of protrusion from the surface of the backrest 84 changes.

[0007]

By the way, there are large individual differences in the physique and sensitivity of the user of the massage machine, and the amount of comfortable holding down for each person varies. Therefore, it is desirable to freely change the amount of pressing. However, as described above, in the conventional massage machine, the size of the three-dimensional trajectory of the treatment element 5 is constant irrespective of the amount of projection of the treatment element 5, but the structure for performing the massage operation is limited. As shown in FIG. 5, the amount worth pressing down from the head direction to the buttocks direction in the massaging massage operation increases as the amount of protrusion of the treatment element 5 increases, and conversely, the amount of protrusion of the treatment element 5 decreases. There is a constraint that it becomes smaller. 5A shows a state in which the amount of protrusion of the treatment element 5 is increased, FIG. 5B shows a state in which the amount of protrusion of the treatment element 5 is medium, and FIG. A is the amount of protrusion of the treatment element 5, B is the pressing amount of the treatment element 5, and the trajectory of the ellipse indicated by the reference sign C is the trajectory of the massage element 5. Since the main shaft 1 is driven to rotate and the treatment element 5 is driven like a locus as indicated by reference numeral C to perform the kneading operation, the larger the treatment element 5 projects, the larger the pressing amount. The smaller the amount by which the treatment element 5 projects, the smaller the pressing amount. The same applies to the beating massage operation. Therefore, when the user wants to perform a point massage such as acupressure, the amount of pressing from the head to the buttocks is determined by the amount of protrusion of the treatment element 5 at that point, and the amount is determined by the user. Is not always a comfortable amount. Conversely, if the amount of protrusion of the treatment element 5 is increased or decreased in order to adjust the pressing amount from the head direction to the buttocks direction to a comfortable amount, the point to be massaged will be shifted. Also, at this time, the pressing amount from the head direction to the buttocks direction is also limited by the mechanical structure of the treatment means, so that even the maximum amount may not be satisfied by some users.

The present invention has been made in view of the above description, and by using a moving means of a conventional treatment means, it is possible to perform acupressure massage with a simple structure and to a user's preference, It is an object to provide a safe and easy-to-use massage machine.

[0009]

In order to solve the above-mentioned problems, a massage machine according to the present invention comprises a chair having a backrest and a seating surface, and a treatment element extending and contracting in a direction substantially perpendicular to the backrest surface for performing a treatment operation. In a massage machine having a treatment means having a mechanism and a moving means for moving the treatment means along the backrest, after adjusting the position of the treatment element by expanding and contracting in a substantially vertical direction of the backrest surface, the moving means is moved. It is characterized in that the treatment means can be moved up and down along the backrest and the amount of movement can be controlled. By moving the treatment means by the moving means as described above, the human body can be pressed by the treatment element, so that the treatment element can be acupressure massaged with the treatment element at an arbitrary position and with an arbitrary pressing amount. With this simple structure, the pressing amount can be freely changed without shifting the shiatsu massage point around the shoulder.

Further, when the treatment means moves downward along the backrest, a pressure for pressing the treatment element against the human body is detected, and control is performed so that the finger pressure by the treatment element becomes equal to or less than a predetermined pressure. Is also preferred. By controlling the pressure that presses the treatment element against the human body, massage can be performed safely without harm to the body.

In order to determine the massage position, the position of the treatment element is adjusted in a direction substantially perpendicular to the back surface, and when the treatment element is moved using the moving means, the pressure for pressing the treatment element against the human body is detected. It is also preferable that the treatment means is moved until the finger pressure of the treatment element reaches a predetermined pressure, and the massage position is determined based on the point. Since the massage position can be automatically determined, the labor of the user can be reduced.

Further, when the operating range of the vertical movement of the treatment means is controlled, a position near the lower point of the operating range is set, and the operating range upward from the point along the backrest is controlled. Is also preferable. By setting the movement lower point position and setting the movement range upward, the massage can be performed safely without being pressed down with a strength more than the user can imagine.

[0013]

The main shaft 1, the screw shaft 14, and the auxiliary shaft 13 are provided between the two blocks 20, 19. And both blocks 20,1
An auxiliary shaft 13, both ends of which are supported by 9, is parallel to the main shaft 1, the screw shaft 14 and the auxiliary shaft 13 via a pair of rotating plates 15, 15 rotatable with respect to the auxiliary shaft 13. The rotating shaft 12 is attached, and the auxiliary shaft 13
The rotation shaft 12 is configured to be rotatable around the. The rotating shaft 12, both ends of which are supported by the pair of rotating plates 15, 15 and which is rotatable with respect to the rotating plate 15, has a pair of crankshafts 12a, 12b whose eccentric directions are opposite to each other. The non-eccentric portions 12 d and 12 e at both ends are supported by the rotating plate 15.

The motor housed in the motor block 20 drives the main shaft 1, the screw shaft 14, the rotary shaft 12, and the pinion 17 to rotate, and also rotates the rotary shaft 1 around the auxiliary shaft 13.
2 is performed. That is, the motor block 20
Pulley 2 attached to the output shaft of the motor projecting downward
8, a driven shaft 3 disposed on the outer surface of the speed reducer block 19;
1 is connected via a belt 29 and a pulley 30, and the driven shaft 31 and a reduction mechanism in the reduction gear block 19 are connected by a clutch 33, pulleys 34 and 36, and a belt 35. I have. The speed reduction mechanism (not shown) in the speed reducer block 19 includes a speed reduction unit and a plurality of clutch units. When the clutch 33 is connected,
The motor output is selectively transmitted to the main shaft 1, the screw shaft 14, or the pinion 17. A worm wheel 41 mounted on the auxiliary shaft 13 is connected to the driven shaft 31 via a clutch 32, a pulley 37, a belt 38, a pulley 39, and a worm 40, and a gear 42 integrated with the worm wheel 41. Are engaged with the gear 43 fixed to the non-eccentric portion 12 d of the rotating shaft 12. When the clutch 32 is connected, the motor output is transmitted to the rotating shaft 12 via each of the above members, and the rotating shaft 12 rotates around the shaft.

A feed screw 25 connected to the motor via pulleys 21, 23, a belt 22, and a clutch 24 is provided on the outer surface of the motor block 20, and a feed screw engaged with the feed screw 25 is provided. The nut 26 and one of the pair of rotating plates 15, 15 are connected by a link 16. When the feed screw 25 rotates with the motor output,
The feed nut 26 that moves in the axial direction of the feed screw 25 moves the rotary plate 15 via the link 16, and as a result, the rotary shaft 12 supported by the rotary plate 15 moves around the auxiliary shaft 13. Perform rotation.

A pair of inner races 2 and 2 are attached to the main shaft 1 at an interval. The two inner rings 2 and 2 are eccentric in the same direction with respect to the main shaft 1 by the same amount and are inclined in opposite directions, and rotate with the main shaft 1 by engagement with the ridges 11 formed on the main shaft 1. And the outer ring 3 is freely slidably mounted on the outer peripheral surface of the main shaft 1. One end of each of the connecting arms 6 and 6 is connected to the outer peripheral surface of the non-eccentric portion of each of the inner rings 2 and 2 so as to freely rotate. The connecting arm 6 that slides in the axial direction of the main shaft 1 together with the inner ring 2 is screwed with the screw shaft 14. Further, since each of the connecting arms 6 and 6 is screwed into a portion of the screw shaft 14 where the screw direction is reversed, both connecting arms 6 and 6 are rotated with the rotation of the screw shaft 14. The pair of inner rings 2 and 2 are moved toward and away from each other.

Arms 4 and 4 are attached to the outer rings 3 and 3 respectively.
The middle of is fixed. A roller-shaped treatment element 5 which is freely rotatable with respect to the arm 4 is attached to the bent portion at the tip of each arm 4, and the other end of one arm 4 is connected to the connection link 8 and the sphere 70. And the rotating shaft 12
The other end of the other arm 4 is connected to the crankshaft 12a of the rotary shaft 12 via the connecting link 8 and the ball 70.
2b. The sphere 70 here is attached so as to be slidable in the axial direction with respect to the rotating shaft 12. The engagement between the connecting link 8 and the crankshafts 12 a and 12 b is achieved by wrapping the sphere 70 at one end of the connecting link 8. It has been done. For this reason, the connecting link 8 can freely rotate three-dimensionally with respect to the crankshafts 12a and 12b, and the connecting portion between the other end of the connecting link 8 and the arm 4 is also formed as a ball joint 44. Therefore, three-dimensional rotation is also possible. Also, the rotating shaft 1
2 The non-eccentric portion 12c at the center and the auxiliary shaft 13 are connected to each other by a connecting plate 9 which is freely rotatable.

Next, an outline of the operation will be described. When the main shaft 1 is rotated by the motor, the inner ring 2 rotating together with the main shaft 1 is eccentric and inclined with respect to the main shaft 1, so that the inner ring 2 is rotatably mounted on the inner ring 2. The treatment element 5 attached via the arm 4
Since the movement of the arm 4 is restricted by the connecting link 8, the movement of drawing the three-dimensional trajectory with the rotation of the main shaft 1, that is, the vertical direction, the axial direction of the main shaft 1, and the main shaft 1 The movement is performed to change the position in the direction of protrusion. A pair of treatment elements 5, which perform such a movement symmetrically,
No. 5 gives a so-called “sleeping massage” to the back of the user. The connection link 8 connected to the arm 4 via the ball joint 44 swings up, down, left, and right with the rotation of the inner race 2, and the connection link 8 and the rotating shaft 12 form a ball joint. Because of the connection with the sphere 70, the operation of the treatment element 5 is performed smoothly.

When the feed screw 25 is rotated by the motor, the auxiliary shaft 1 is rotated via the link 16 and the rotary plate 15.
When the rotating shaft 12 is rotated about 3, the arm 4 and the outer ring 3 rotate around the inner ring 2 and the treatment element 5 moves in the front direction in which the back of the user is located. Since the amount of protrusion is changed, when the main shaft 1 is rotated to obtain a massage, when the amount of protrusion of the treatment element 5 is increased, a strong “sticky” massage is performed, and when the amount of protrusion is reduced, It is possible to adjust the strength of performing a weak “slippery massage”, and by increasing the amount of protrusion, the massage to the shoulder can be performed from above, not from behind. ing.

When the rotary shaft 12 is rotated instead of the main shaft 1, the crankshaft 1 which is an eccentric portion of the rotary shaft 12 is rotated.
In this case, since the arms 4 are connected to the 2a, 12b via the connecting link 8, the crankshafts 12a, 1
The connecting link 8 moved as the eccentric rotation of 2b moves the arm 4 connected by the ball joint 44. At this time, the movement of the arm 4 rotates together with the outer ring 3 around the stopped inner ring 2. Because of the movement, the treatment element 5 at the tip of the arm 4 has a linear reciprocating motion in a substantially vertical direction when viewed from the front, depending on the position of the inner ring 2, and performs a tapping massage. Further, both crankshafts 12a, 12b of the rotary shaft 12 as the eccentric member 7 are provided.
Since the eccentric direction is reversed by 180 °, the tapping massage operation is performed alternately in both treatment elements 5,5.

When the pinion 17 is rotated by the motor, the massage machine is operated by a backrest 8 of a chair which is a treatment table due to the engagement between the rack 91 and the pinion 17.
4 is moved up and down along the rail 90. Therefore, the position of the treatment element 5 can be changed up and down. At this time, since the roller-shaped treatment element 5 rolls along the back of the human body, it is possible to obtain a rolling massage in which the treatment element 5 touches the back of the human body.

When the screw shaft 14 is further rotated, the treatment element 5 moves in the axial direction of the main shaft 1, and in order to change the interval between the pair of treatment elements 5, the treatment target is the shoulder. ,
The position of the treatment element 5 in the axial direction, that is, the position in the width direction can be changed depending on whether it is the neck or the like.

The tapping massage operation by rotating the rotary shaft 12 around the axis is performed by the pinion 1.
When executed in parallel with the movement operation by the rotation of 7,
"Tapping rolling massage" in which the treatment element 5 performs a tapping motion while moving up and down, that is, a massage in which a portion to which the tapping motion is applied changes sequentially up and down can be obtained.

According to the present invention, in the massage machine constructed as described above, when the vicinity of the user's shoulder is pressed by the treatment element 5 to perform acupressure massage, the driving is controlled as follows. In other words, in the present invention, after the position of the treatment element 5 is adjusted by extending and contracting in a direction substantially perpendicular to the surface of the backrest 84, the treatment means is moved up and down along the backrest 84 using the moving means, and the amount of movement is controlled. I can do it.

First, as shown in FIG. 3A, by moving the treatment element 5 so as to expand and contract in a direction substantially perpendicular to the surface of the backrest 84, the amount of protrusion from the backrest 84 is adjusted. At this time, the feed screw 25 is rotated by the motor, the rotation shaft 12 is rotated around the auxiliary shaft 13 via the link 16 and the rotation plate 15, and the amount of protrusion of the treatment element 5 is reduced as shown in FIG. It changes and is adjusted to the point around the shoulder that the user wants to massage. Here, the symbol D is a massage point. Next, the massage machine main body having the treatment means such as the treatment element 5 is driven up and down along the backrest 84 by the movement means while the projection amount of the treatment element 5 is maintained, and the treatment means is moved in the direction of the buttocks. 3 (b), the treatment element 5 presses a predetermined point around the shoulder of the user, and the acupressure massage is performed. That is, when the pinion 17 is rotated by the motor, the rack 91 and the pinion 17 are rotated.
The massage machine body moves up and down along the backrest 84 of the chair by the meshing of the massager, the treatment element 5 moves up and down together with the massage machine body, and the treatment element 5 descends so that the treatment element 5 Shiatsu massage is given to the point around the shoulder. At this time, in order to press the treatment element 5 to the massage point by moving the treatment means up and down, the amount of pressing at the time of performing the acupressure massage can be freely changed by changing the moving amount, and the acupressure massage according to the user can be performed. Can be. The protruding position of the treatment element 5 can be acupressure massaged by the treatment element 5 at an arbitrary position and an arbitrary pressing amount as described above, without shifting the shiatsu massage point around the shoulder with a simple structure.
The holding amount can be freely changed.

By moving the treatment means having the treatment element 5 downward by driving the pinion 17 by the motor as described above, the treatment element 5 is moved downward and the treatment element 5 is pressed to perform acupressure massage. The pressure applied by the treatment element 5 to the human body is detected, and the finger pressure by the treatment element is controlled to be equal to or lower than a predetermined pressure. For example,
When the treatment element 5 is pressed against the human body, the control circuit attached to the massage machine reads the load applied to the motor,
If the treatment element 5 presses a point around the shoulder with a force of a predetermined load or more for some reason, the treatment means is controlled to move in the head direction. Here the treatment child 5
Although the method of reading the load of the motor is used to detect the pressure applied by the user, a method of measuring the pressing pressure by a pressure sensor may be used. In this case, when the treatment element 5 is detected to be pressed with a predetermined pressure or more, the movement means controls the treatment means to move upward, but the movement of the treatment means may be stopped. . By controlling the pressure of pressing the treatment element 5 against the human body as described above, massage can be performed safely without harm to the body.

FIG. 4 explains the control of another example of the present invention. As shown in FIG. 4A, the treatment element 5 is maintained in a state where the treatment element 5 is protruded by a predetermined amount in the vicinity of the upper part of the backrest 84, and the treatment means is moved to the rail 90 of the backrest 84.
Move along the buttocks. Then, as shown in FIG. 4 (b), when the control circuit for reading the load applied to the motor comes into contact with the vicinity of the shoulder of the user and determines that the predetermined load has been reached (the treatment is performed while detecting the pressure of pressing the treatment element against the human body). When it is determined that the treatment means has been moved until the child's finger pressure reaches a predetermined pressure), it is recognized that there is a massage point at that position (the massage position is determined based on that point). Then, as shown in FIG. 4C, the position is set as the lower point F of the movement range E, and the movement range E is set further in the head direction of the backrest 84, and the acupressure massage is repeated. Here, a method of reading the load of the motor is used to detect the pressure applied by the treatment element 5, but a method of measuring the pressing pressure by a pressure sensor may be used. By doing so, the massage position can be automatically determined, so that the user's labor can be reduced. Further, by setting the position of the movement lower point F and setting the movement range E upward, the massage can be performed safely without being pressed down with a strength more than the user can imagine. If the operation device is equipped with a strength button, when the strong mode is selected, the lower point F moves toward the buttocks,
Conversely, when the weak mode is selected, the position of the lower point F is moved toward the head, and the strength can be freely changed.

And the amount of movement can be controlled, so that the treatment element can be acupressure massaged with the treatment element at an arbitrary position and an arbitrary pressing amount. The pressing amount can be freely changed without shifting the massage point.
