Description

  The present invention relates to a massage machine including a treatment element for massaging a user, and a chair type massage machine including the massage machine.

What has been conventionally known as a massage machine capable of performing massage on a user is one provided with a treatment element (smearing ball) that operates on the user. As such a massage machine, for example, as shown in Patent Document 1, there is one having a pair of first and second treatment elements, and treatment is performed by moving the treatment elements toward or away from each other. Massage can be performed on the person.
In the massage machine shown in Patent Document 1, a worm wheel and a coaxial first intermediate gear are meshed with a partial gear formed on the arm portion of the first treatment element, and formed on the arm portion of the second treatment element. By engaging the second intermediate gear branched from the first intermediate gear with the partial gear and rotating the first intermediate gear, the two treatment elements are swung to approach or separate and massage by pinching is performed. ing.

JP-A-9-299429 (see FIG. 7)

However, the conventional massage machine described in Patent Document 1 is a power transmission system in which an intermediate gear is engaged with a partial gear formed on an arm portion to which a treatment element is attached. There is a problem that the swinging range is likely to be shifted, and it is difficult to realize an accurate pinching motion.
Furthermore, in the massage machine of Patent Document 1, the swinging direction of both treatment elements is set to a direction in one vertical plane because of the configuration, and it is very difficult to change the swinging direction of each treatment element. Further, this massage machine has a problem that the degree of freedom of arrangement of the treatment elements is low, and it is difficult to increase the number of treatment elements for performing massage on a predetermined affected part, more than two.
Accordingly, the present invention has been made in view of the above-described problems, a massage machine that is less likely to shift in the swing range of the treatment element, and that has a high degree of freedom in changing the number and swing direction of the treatment elements, and An object of the present invention is to provide a chair type massage machine equipped with the same.

A plurality of treatment elements, a movement base that is driven to move forward and backward between the base member and the treatment element, and a movement of the movement base to move the first and second treatment elements. A link member pivotally attached to the first and second treatment elements for conversion into a dynamic motion.

According to this configuration, each of the treatment elements is pivotally attached to the protruding member protruding from the base member toward the user, and the treatment elements are also pivotally attached to the link member. Then, when the moving base is driven to move forward and backward, the link member can convert the forward and backward movement into the swinging movement of the first and second treatment elements. In this way, the treatment element is supported and pivoted while being pivotally attached to both the projecting member and the link member. Does not occur.
In addition, since the movement base movement is converted into the swing motion of each treatment element via the link member, the swing direction of each treatment element can be changed arbitrarily by changing the direction of the swing axis. And it can be set easily. Further, even if the number of treatment elements is increased, power can be obtained from the common moving base.

In this massage machine, the treatment element can be composed of a plurality of first treatment elements and a smaller number of second treatment elements than the first treatment elements.
And in this massage machine, the protruding member on which the second treatment element is pivotally mounted comprises a rotation shaft extending in the advancing / retreating direction of the moving base, and the moving base and the advancing / retreating movement are both, A rotation link connected to the moving base is provided so that relative rotation is possible, and the second treatment element pivotally attached to the rotation shaft and the rotation link are interlocked and connected by the link member. Is preferred.

  According to this configuration, the rotation link moves forward and backward with the movement base by the movement base moving forward and backward, and the rotation link and the second treatment element are interlocked and connected by the link member. I can exercise. Further, since the rotary link connected to the rotation shaft via the second treatment element and the link member is connected so as to be relatively rotatable with respect to the moving base, the rotation shaft is rotated around its axis. Can rotate to. That is, when the second treatment element swings, the pinching operation can be performed by co-operation with the first treatment element, and the kneading operation can be performed by the second treatment element rotating, and the compound treatment Massage can be performed.

In the massage machine, the swing direction of each treatment element is set so that the first treatment element approaches or separates from each other and the first treatment element approaches or separates from each other at the same time. Is preferred.
According to this, massage by pinching can be performed by swinging each treatment element. Furthermore, since the first treatment elements approach or separate from each other, the massage by the pinching can achieve pinching itching close to human hands.

Further, the first treatment elements are arranged side by side so that the plurality of first treatment elements can be regarded as fingers other than the thumb and the second treatment element can be regarded as a thumb. It is preferable to be provided facing these first treatment elements.
According to this, since the first treatment element can be regarded as a finger other than the thumb and the second treatment element can be regarded as a thumb, a suitable massage closer to the hand can be performed.

Moreover, the chair type massage machine of this invention is provided with the seat part, the backrest part provided in the back side of this seat part, and the massage apparatus with which at least one of the said seat part and the said backrest part was equipped. The massage device can be the massage machine described above.

  According to the present invention, the treatment element is supported and pivoted while being pivotally attached to both the projecting member and the link member. Misalignment does not occur. In addition, by changing the direction of the swing axis of each treatment element, the swing direction of each treatment element can be set arbitrarily and easily, and even if the number of treatment elements is increased, power can be generated from a common moving base. can get. Therefore, it is possible to provide a massage machine with a high degree of freedom in changing the number and swing directions of the treatment elements.

FIG. 3 is a perspective view showing an embodiment of a massage unit equipped with the massage machine of the present invention (first embodiment), and FIG. 4 is a perspective view showing the main part thereof. FIG. 5 is a sectional side view of the massage machine.
The massage unit 8 has a frame 28, and the massage machine 7 is mounted on the frame 28. Rollers 30 are rotatably attached to the four corners of the substantially rectangular body portion 28b of the frame 28, respectively. The massage unit 8 can move along the guide path 6 by at least one of these rollers 30 being rotationally driven. Specifically, although not shown, at least one of the four rollers 30 has teeth formed on the outer peripheral surface thereof to form a pinion.

Then, the rotation of the motor mounted on the massage unit 8 is transmitted to the pinion via a speed reduction mechanism, and the massage unit 8 is moved along the guide passage 6 by rotating the pinion.

First, a first embodiment of the massage machine of the present invention will be described.
This massage machine 7 is provided with a treatment element (massage ball) for massaging the user. The treatment element of the present invention includes a plurality of first treatment elements and a smaller number of second treatment elements than the first treatment elements. In addition, the treatment element shown to the figure consists of the two 1st treatment elements 1a and 1b and the one 2nd treatment element 2. FIG. And the massage machine 7 of this invention is provided with the stagnation drive mechanism 11 which makes these 1st treatment elements 1a and 1b and the 2nd treatment element 2 approach or separate from each other.

  The two first treatment elements 1a and 1b are arranged side by side, and the second treatment element 2 is provided to face the first treatment elements 1a and 1b. As a result, the stagnation drive mechanism 11 causes the first treatment elements 1a, 1b and the second treatment element 2 to move toward or away from each other, so that the first treatment elements 1a, 1b (The index finger and the middle finger) and the second treatment element 2 can be regarded as a thumb, and these three treatment elements can be massaged by pinching. In other words, a suitable massage approximated by a massage by a human hand can be performed. In addition, the first treatment element 1a, 1b and the second treatment element 2 are substantially spherical in size, and the first treatment element 1a, 1b is larger than the second treatment element 2.

The stagnation drive mechanism 11 will be specifically described.
The stagnation drive mechanism 11 includes a base member 29 having a flat plate-like main body portion 29a, and a plurality of projecting members 20 project from the main body portion 29a. The stagnation drive mechanism 11 shown in the figure includes three projecting members 20 corresponding to the number of the treatment elements (see FIG. 4). Each protruding member 20 is a straight cylindrical member, and the base end side is attached to the base member 29.
Then, one of the first treatment elements 1a and 1b and the second treatment element 2 is pivotally attached to the distal end side of the protruding member 20 so as to be swingable. Thereby, the protruding direction of the protruding member 20 is the direction toward the user, and the protruding direction (axial direction) is the surface of the flat main body portion 29 a of the base member 29. , That is, a direction parallel to the normal direction of the base member 29 (axial center C1 direction).

  4 and 5, the pair of first treatment elements 1a and 1b are fixed to the central portion of the first fixing member 17a, respectively, and the fixing member 17a is at one end of the distal end portion of the protruding member 20b. It is pivotally attached to the rocker. And the 2nd treatment element 2 is being fixed to the center part of the 2nd fixing member 17b, and this fixing member 17b is pivotably attached to the front-end | tip part of the protrusion member 20a in the one end part.

  Further, the stagnation drive mechanism 11 includes a plate-like (flat plate) moving base 39. The moving base 39 is provided between the base member 29 and the plurality of treatment elements so as to be able to advance and retract toward the user, and is driven in that direction. The forward / backward drive direction of the moving base 39 is parallel to the axis C 1, and the forward / backward drive is performed by drive means 11 a provided in the stagnation drive mechanism 11. The projecting members 20a and 20b penetrate the moving base 39 in the thickness direction (see FIG. 5). The moving base 39 can be configured to smoothly move linearly while being guided by the projecting members 20a and 20b.

  FIG. 6 is a view of the massage machine 7 as seen from the back side (the side opposite to the treatment element), and FIG. 7 is a view showing a part of the driving means 11a. 5, 6, and 7, the driving means 11 a includes a motor 41, a rotating shaft 42 that is rotatably supported on the back surface of the base member 29, and a cam 43 that rotates integrally with the rotating shaft 42. The rotating shaft 42 and the cam 43 are configured to be rotationally driven by the rotation of the motor 41. Then, when the rotating cam 43 comes into contact with the contact 44 provided on the back surface 39 a side of the moving base 39, the moving base 39 moves toward and away from the base member 29. The forward / backward driving is performed. The power transmission between the motor 41 and the rotating shaft 42 is performed by a belt. The motor 41 is preferably a geared motor.

3, 4, and 5, the stagnation drive mechanism 11 is further provided between the movement base 39 and the second treatment element 2 and between the movement base 39 and the first treatment elements 1 a and 1 b. The link members 22a and 22b are provided. More specifically, the link member 22b is a straight member on the first treatment element 1a, 1b side, and one end of the link member 22b is pivotally attached to a part of the peripheral edge of the moving base 39. The other end is pivotally attached to the other end of the fixing member 17a that fixes the first treatment elements 1a and 1b.
On the second treatment element 2 side, the link member 22a is a linear member, one end of which is pivotally attached to the moving base 39 side, and the other end is connected to the second treatment element 2. It is pivotally attached to the other end of the fixed member 17b. The link member 22 a is pivotally attached to a rotary link 23 described later, and is swingable with respect to the moving base 39 via the rotary link 23.
As described above, the fixing members 17b and 17a fixing the first and second treatment elements are pivotally attached to the projecting members 20a and 20b projecting from the base member 29 toward the user. At the same time, the link members 22a and 22b on the side of the moving base 39 that is driven forward and backward are also pivoted.

According to the stagnation drive mechanism 11 configured as described above, the moving base 39 can move forward and backward in a straight line toward the user by the driving means 11 a, and the link members 22 a and 22 b are connected to the moving base 39. The advancing and retreating linear motion can be converted into the swinging motion of the first treatment element 1a, 1b and the second treatment element 2.
Furthermore, according to the kneading drive mechanism 11, a plurality of treatment elements can be simultaneously swung by advancing and retreating driving of one moving base 39, and massage by pinching can be performed by these treatment elements. Further, since the forward / backward movement of the moving base 39 is converted into the swing motion of each treatment element via the link members 22a and 22b, the direction of the swing axis of each treatment element (fixing members 17a and 17b) is changed. By doing so, the swinging direction of each treatment element can be set arbitrarily and easily. Furthermore, even if the number of treatment elements is increased from three, power can be obtained from one common moving base 39, so that the structure can be simplified even if the number of treatment elements increases.
Furthermore, each treatment element is supported in a state of being pivotally attached to both the projecting members 20a and 20b and the link members 22a and 22b, and performs a swinging motion, and since the driving means 11a does not have a gear, Unlike the mechanism having the gear, it is possible to prevent the shift of the swing range of the treatment element due to the backlash between the gears.

The massage exercise by the pinching performed by the massage machine 7 will be further described. FIG. 8 is a view of the treatment element along the direction of the axis C1.
In FIG. 8, a plurality of first treatment elements 1a and 1b constitute a treatment element group, and the stagnation drive mechanism 11 causes the treatment element group and the single second treatment element 2 to approach or separate from each other. In addition, the first treatment elements 1a and 1b in the treatment element group are driven so as to approach or separate from each other during the approach or separation movement. That is, the massage machine 7 is configured so that the treatment element group and the second treatment element 2 approach or separate from each other and the plurality of first treatment elements 1a and 1b approach or separate from each other. The swing direction of the child is set.
5 and 8 is a straight line in a direction perpendicular to the surface of the main body portion 29a of the base member 29, and is set at the center of the base member 29. And the 1st treatment element 1a, 1b and the 2nd treatment element 2 are arrange | positioned so that the said axial center C1 may be surrounded from the circumferential direction centering on this axial center C1, and the 1st treatment element 1a, 1b and 2nd The treatment element 2 is configured to be able to swing toward or away from the axis C1 by swinging.

This will be described in detail with reference to FIG. 5 and FIG. 8. In each fixing member 17a to which the first treatment elements 1a and 1b are respectively attached, a pivot shaft that pivots the fixing member 17a and the link member 22b. 18 is located at a position farther from the axis C1 than the pivot shaft 19 that pivots the fixing member 17a and the projecting member 20b. As shown in FIG. It can be set as the arrangement | positioning which both the pivoting shafts 18 and 19 exist on the straight line extended radially from C1.
Further, in the fixing member 17b to which the second treatment element 2 is attached, a pivot shaft 24 pivotally mounting the fixing member 17b and the link member 22a pivots the fixing member 17b and the rotation shaft 20a. As shown in FIG. 8, the pivot shafts 24 and 25 are arranged on a straight line extending radially from the pivot center C1, for example, as shown in FIG. You can take existing arrangements.

That is, when the treatment element is viewed along the direction of the axis C1, each of the first and second treatment elements is arranged on a plurality of straight lines extending radially from the axis C1, and approaches or separates. The moving direction is seen as the direction along each straight line.
Alternatively, the pivoting shafts 18 and 19 and the pivoting shafts 24 and 25 may be other than the arrangement that exists on a straight line extending radially from the axis C1. That is, the operation direction of the first treatment element 1a, 1b is an operation direction approaching or separating from the second treatment element 2 side, and the operation direction of the second treatment element 2 is the first treatment element 1a, Any movement direction that approaches or separates from the 1b side may be used. When the treatment element is viewed along the direction of the axis C1, the straight line in the operation direction of the first treatment element 1a and the straight line in the movement direction of the first treatment element 1b can be in a direction intersecting each other. .
According to this configuration, when a treatment element group including a plurality of first treatment elements 1a and 1b and a single second treatment element 2 approach or separate from each other and perform pinching, the plurality of first treatment elements Since 1a and 1b also mutually approach or leave | separate, the massage by the suitable pinch massage approximated by the massage by a human hand with respect to a to-be-treated person can be performed.
Alternatively, when the treatment element is viewed along the direction of the axis C1, the straight line in the movement direction of the first treatment element 1a and the straight line in the movement direction of the first treatment element 1b may be parallel.

Further, in FIG. 5, the stagnation drive mechanism 11 has a function of driving so that the approach or separation stroke of the second treatment element 2 is larger than the same stroke of the first treatment elements 1 a and 1 b. This can be realized by configuring the swing angle of the second treatment element 2 to be larger than the swing angle of the first treatment elements 1a and 1b. Specifically, the distance between the first pivot shaft 24 and the second pivot shaft 25 on the second treatment element 2 side is such that the first pivot on each of the first therapy elements 1a and 1b side. It is set to be smaller than the interval between the landing shaft 18 and the second pivot shaft 19. Thereby, even if the advance / retreat stroke of the movement base 39 for swinging the first and second treatment elements is the same, the strokes of the first and second treatment elements are different.
As described above, the stroke of the second treatment element 2 that is regarded as a thumb is larger than the stroke of the first treatment elements 1a and 1b that are regarded as fingers other than the thumb, and the massage by the hand of the person performed by moving the thumb greatly. A closer massage feeling can be achieved.

Furthermore, the massaging machine 7 of the present invention is configured so that the first treatment element 1a, 1b and the second treatment element 2 are driven so as to perform a massage motion by pinching as the first treatment element 1a, 1b and the second treatment element 2 approach or separate from each other. In addition to the mechanism 11, a second drive mechanism 12 is provided. This 2nd drive mechanism 12 drives so that the 2nd treatment element 2 may perform more complicated massage exercise | movement other than this approach or separation.
This complicated massage exercise to be performed on the second treatment element 2 by the second drive mechanism 12 may be a kneading operation that rotates the second treatment element 2 along a circular path with respect to the user (human body). it can. Specifically, the protruding member 20a to which the second treatment element 2 is attached to the tip is a rotating shaft, and this kneading operation is a rotation around the axis C2 (FIG. 5) of the rotating shaft 20a. Is obtained from the exercise performed by. According to this configuration, the structure for performing the kneading operation can be simplified. Since the rotation shaft 20a is the protruding member, the rotation shaft 20a is a member extending in the advancing / retreating direction of the moving base 39, and the axis C2 of the rotation shaft 20a and the axis C1 of the base member 29 are parallel to each other. It becomes.
In addition, the circular orbit of the 2nd treatment element 2 has the case of the surroundings of the axis parallel to the reference axis C1 (axis) of a massage machine, and the case of the periphery of the inclined axis | shaft which cross | intersects the said reference axis C1. As will be described later, this is because the center line of the bearing (rolling bearing) 23d is inclined with respect to the axis C1. And when this circular orbit is made around an inclined axis, the distance of the second treatment element 2 to the body of the user can be changed, so the massage force (pressing force) by the second treatment element 2 is changed. Can be made.

As shown in FIG. 5, the rotation shaft 20 a on which the second treatment element 2 is pivotally attached passes through the base member 29 and the moving base 39. The rotation shaft 20a is rotatable with respect to the rolling bearings attached to the base member 29 and the moving base 39, and the rotation shaft 20a is centered on the base member 29. Directional movement is restricted and attached. The movement base 39 is movable in the direction of the axis C2 with respect to the rotation shaft 20a.
And the bevel gear 45 is being fixed to the base end part opposite to the 2nd treatment element 2 side of the autorotation shaft 20a, and the said bevel gear 45 is attached to the bevel gear 48 which the 2nd drive mechanism 12 has. The second drive mechanism 12 rotates the bevel gear 48 so that the rotation shaft 20a can rotate. That is, the second drive mechanism 12 is a rotation drive mechanism that rotates the rotation shaft 20a.

  The structure of the second drive mechanism 12 will be further described. The second drive mechanism 12 includes a motor 46 and a rotary shaft 47 that is rotatably supported on the back surface of the base member 29 in FIGS. 5 and 6. The bevel gear 48 is configured to rotate integrally with the rotary shaft 47. Therefore, when the rotation shaft 47 and the bevel gear 48 are driven to rotate by the rotation of the motor 46, the rotation shaft 20a rotates about its axis C2 (rotation axis), and the fixing member 17b is formed on the tip end side of the rotation shaft 20a. The 2nd treatment element 2 attached via is rotated centering on the axial center C2. The motor 46 is preferably a geared motor.

The fixing member 17b that fixes the second treatment element 2 is pivotally attached not only to the rotation shaft 20a but also to the link member 22a that is swingably attached to the moving base 39 as described above. Accordingly, in order to rotate the second treatment element 2 around the axis C2, a rotation link 23 that is rotatable is provided on the moving base 39, and a link member 22a is pivotally attached to the rotation link 23. ing. And the 2nd treatment element 2 and the rotating shaft 20a rotate with these rotation links 23 and the link member 22a. That is, the rotary link 23 moves forward and backward together with the moving base 39, but is connected to the moving base 39 so as to be rotatable relative to the moving base 39 about the axis C2.
The rotation link 23 will be further described. The rotation link 23 includes an attachment portion 23a through which the rotation shaft 20a is inserted, and a pivot attachment portion 23b pivotally attached to the link member 22a. The mounting portion 23a has a cylindrical portion 23c, and is slidable with the rotation shaft 20a on its inner peripheral surface, and a bearing 23d (rolling bearing) is fitted on the outer peripheral surface thereof. In the moving base 39, a bearing hole 39b is formed in a part of a through hole through which the rotation shaft 20a is inserted, and the bearing 23d is fitted in the bearing hole 39b. Further, a slide bush 39e is fitted into a part of the through hole, and the slide bush 39e is slidably rotatable on the rotation shaft 20a, and the rotation shaft 20a is slidably rotatable with respect to the slide bush 39a. It is fitted. Thereby, the rotation link 23 becomes rotatable with respect to the movement base 39 around the rotation shaft 20a (axis C2). And the 2nd treatment element 2 (fixed member 17b) pivotally attached to the autorotation shaft 20a and the pivoting part 23b of the rotation link 23 provided on the movement base 39 are interlockedly connected by the link member 22a. .

According to the above, the rotation link 23 connected to the rotation shaft 20a via the fixing member 17b and the link member 22a is configured to be relatively rotatable with respect to the moving base 39. The shaft 20a can rotate around its axis C2. Thereby, the 2nd drive mechanism 12 can rotate the autorotation axis | shaft 20a to which the 2nd treatment element 2 is pivoted, the said 2nd treatment element 2 rotates, and massage is massaged by a massage. It can be performed.
Further, the rotation link 23 moves forward and backward together with the movement base 39 by the forward and backward drive of the movement base 39, and the fixing member 17b fixing the second treatment element 2 and the rotation link 23 are interlocked and connected by the link member 22a. Therefore, the second treatment element 2 can be swung around the pivot axis (the pivot axis 25) with the rotation axis 20a, and the second treatment element 2 works together with the first treatment elements 1a and 1b. By this, it is possible to perform massage with pinching on the user.

  In addition, the shaft center of the bearing hole 39b of the moving base 39 and the shaft center of the cylindrical portion 23c of the rotary link 23 are inclined with respect to the shaft center C2. That is, the center line of the bearing 23d is inclined with respect to the axis C2 and the axis C1. Therefore, the rotation link 23 can rotate around the axis inclined to the axis C2. According to this, the distance between the second treatment element 2 and the base member 29 changes while the second treatment element 2 is rotated about the axis C2 by the rotation of the rotation shaft 20a, and the second treatment element 2 changes. The contact strength (pressing strength) of the child 2 to the user changes.

  As described above, according to the first drive mechanism 11 and the second drive mechanism 12, the first treatment elements 1a and 1b and the second treatment element 2 move toward or away from each other, and the second treatment element 2 More complicated massage movements other than approach or separation, that is, massage movement by kneading can be performed. Therefore, this massage machine 7 can perform a variety of massages for the user.

  Further, the massage machine 7 performs a normal squeezing operation that sandwiches the user by the approach or separation of the first treatment element 1a, 1b and the second treatment element 2, while the second treatment element 2 is applied to the treatment person. Since the kneading motion can be performed, it is possible to perform a combined massage by the pinching motion and the kneading motion on the same affected part. And in order for the massage machine 7 to perform this compound massage to a treatment element, it is further provided with the control means 10 which operates the 1st and 2nd drive mechanisms 11 and 12 simultaneously (refer FIG. 9). FIG. 9 is a block diagram showing an outline of a mechanism provided in the massage machine 7 of the present invention. That is, the control means 10 can give an operation signal to each of the motors 41 and 46 (see FIG. 6) included in the first and second drive mechanisms 11 and 12.

For the pinching operation, the first treatment elements 1a and 1b and the second treatment element 2 have the same oscillation period, and the period is preferably set to 2 to 4 seconds. Moreover, it is preferable that the period of the kneading operation by the second treatment element 2, that is, the rotation period is set to 2 to 4 seconds.
Since both the pinching operation and the kneading operation performed with respect to the same affected part as the composite massage are both the itching operation, it is preferable to operate them with substantially the same cycle. Specifically, the period of both is preferably set to 2 to 4 seconds.

Further, in the rotation operation of the second treatment element 2 in the kneading operation, it is preferable that the diameter of the rotation locus around the rotation axis 20a is set to about 50 mm to 60 mm. Further, the moving stroke when the second treatment element 2 is moved along the direction of the axis C2 by the rotary link 23 provided to be inclined with respect to the axis C2 of the rotation axis 20a is 5 mm to 10 mm. It is preferable to set the degree.
Further, in the swinging operation of the first and second treatment elements in the pinching operation, the movement distance of the first and second treatment elements in the direction orthogonal to the axis C1 is preferably set to 15 mm to 25 mm. .

The function further provided in the second drive mechanism 12 will be described.
As described above, when the second drive mechanism 12 is continuously driven, the second treatment element 2 is continuously rotated, and it is possible to knead the user, but the second drive mechanism 12 is provided. As other functions, there is a function as a direction switching mechanism 13 that changes a direction in which the second treatment element 2 approaches or separates from the first treatment elements 1a and 1b.

That is, the direction switching mechanism 13 can change the direction in which the second treatment element 2 approaches or separates by rotating the rotation shaft 20a attached to the distal end of the second treatment element 2.
The operation of the second treatment element 2 by the direction switching mechanism 13 will be specifically described. When the rotation shaft 20a is rotated counterclockwise by a predetermined angle θ around the axis C2 from the state of FIG. The child 2 is displaced to the position indicated by the two-dot chain line. Thereby, the swinging direction of the second treatment element 2 changes from the left-right direction toward the axis C1 in FIG. 8 to an oblique direction toward the first treatment element 1a on one side (lower side in FIG. 8). In this state, the rotating shaft 20a is stopped, and the first drive mechanism 11 causes the first and second treatment elements to perform the pinching operation so that massage in different pinching directions can be performed.

  In this manner, the rotation shaft 20a can be rotated by a predetermined angle by operating the direction switching mechanism 13 intermittently. Therefore, the direction of the swing direction of the second treatment element 2 can be changed every moment, and the direction in which the second treatment element 2 approaches or separates from the first treatment elements 1a and 1b can be changed. Thereby, this massage machine 7 can perform the massage which is rich in change with respect to the user. Furthermore, by changing the direction in which the second treatment element 2 approaches or separates, the degree of pressing of the second treatment element 2 against the user can be slightly changed. Thereby, the suitable massage approximated by the massage by a human hand can be performed. Then, by configuring the direction switching mechanism 13 using the rotation shaft 20a, switching of the pinching direction can be realized with a simple structure.

Still another mechanism provided in the massage machine 7 of the present invention will be described.
In FIG. 3, the base member 29 on which treatment elements 1a, 1b, and 2 for massaging a user are mounted is a plate-like movable base that can swing itself. That is, the massage machine 7 includes a leveling first support member 26 that supports the movable base 29 in a swingable manner, and further includes a rolling support that rotatably supports the first support member 26. The second support member 27 is provided.

The first support member 26 supports both ends of the movable base 29 so as to be swingable about an in-plane axial center C3. The axial center C3 in the in-plane direction exists on the surface of the movable base 29, the back surface, or a surface parallel to them.
The second support member 27 supports the first support member 26 so as to be rotatable around the axis of the movable base 29 in the normal direction. The axis in the normal direction is the axis C1.
The massage machine 7 further includes a leveling drive mechanism 31 for swinging the movable base 29 relative to the first support member 26 and a mechanism for rotating the first support member 26 relative to the second support member 27. And a rolling drive mechanism 32.

  More specifically, the movable base (the base member) 29 has a disk-shaped main body portion 29a, and the axis C1 passes in a direction orthogonal to the center of the main body portion 29a. Yes. In addition, the movable base 29 has a pair of flange portions 29b fixed to the main body portion 29a so as to face each other at 180 °. In each flange portion 29b, the movable base 29 is swingably attached to the first support member 26 about the axis C3.

The first support member 26 is an annular member that surrounds the movable base 29 around the axis C1. The pair of flange portions 29b of the movable base 29 are connected to a pair of mounting portions (not shown) provided 180 ° apart on the inner peripheral surface side of the first support member 26. It is attached via a member (not shown).
The second support member 27 is an annular member that is externally fitted to the first support member 26 about the axis C1. And the 1st support member 26 is made into the 2nd support member 27 by the guide uneven part (not shown) formed between the outer peripheral part of the 1st support member 26, and the inner peripheral part of the 2nd support member 27. On the other hand, it can rotate and slide. And the 2nd support member 27 is attached to the flame | frame 28 with which the massage unit 8 is provided via the arm part 27a.
As a result, the movable base 29 on which the treatment element is mounted is swingable about the axis C3 in the in-plane direction of the movable base 29 and is rotatable about the axis C1 orthogonal to the movable base 29. It is said.

The rolling drive mechanism 32 includes a cylindrical first winding member 34 that is rotationally driven by a motor 33, and a wire 35 that is laid between the first winding member 34 and the first support member 26. Have. The wire 35 can rotate the first support member 26 about the axis C <b> 1 by the rotation of the first winding member 34. Power transmission between the motor 33 and the first winding member 34 is performed by a belt. The motor 33 and the first winding member 34 are attached to the massage unit 8 on the frame 28 side and apart from the first support member 26 side.
Then, the wire 35 passes from the first winding member 34 through one cylindrical guide portion 50a formed in the second support member 27, and is formed in a groove formed on the outer peripheral surface of the first support member 26. 26 b is wound around the axis C <b> 1, passes through the other cylindrical guide portion 50 b, and is wound around the first winding member 34. Therefore, when the first winding member 34 rotates forward or backward, the wire 35 can drive the first support member 26 to rotate about the axis C1 in one direction or the other direction.

The leveling drive mechanism 31 includes a cylindrical second winding member 37 that is rotationally driven by a motor 36, and a wire 38 provided between the second winding member 37 and the movable base 29. ing. The wire 38 can swing the movable base 29 about the axis C <b> 3 by the rotation of the second winding member 37. Power transmission between the motor 36 and the second winding member 37 side is performed by a belt. The motor 36 and the second winding member 37 are attached to the frame 28 side of the massage unit 8 and away from the movable base 29 side.
The wire 38 is formed on the outer peripheral surface of the one flange portion 29b of the movable base 29 from the second winding member 37 through the one cylindrical guide portion 49a formed on the first support member 26. It is wound around the concave groove 29d centered on the axis C3, passes through the other cylindrical guide portion 49b, and is wound around the second winding member 37. Therefore, when the second winding member 37 rotates forward or backward about a predetermined angle, the wire 38 can swing the movable base 29 around the axis C3 in one direction or the other direction.

  As described above, the wires 35 and 38 are used for the swing of the movable base 29 and the rotation of the first support member 26 supporting the movable base 29 without using a combination of gears. There is an effect. For example, as a comparative example, when a gear drive mechanism that swings the movable base using only a combination of gears is used as a comparative example, there is a restriction on the arrangement of the gears, and the volume for the arrangement of the gears increases. However, with the use of the wires 35 and 38, the relative positions such as the distances between the first winding member 34 and the second winding member 37 and the movable base 29 can be freely set to some extent. The degree of freedom of arrangement of the first winding member 34 and the second winding member 37 and the movable base 29 is increased, and the movable base 29 can also operate with respect to the frame 28. Furthermore, the power transmission unit can be made compact.

  According to the leveling drive mechanism 31, the movable base 29 can be swung with respect to the first support member 26, and the leveling in which the heights of the first and second treatment elements change with respect to the user. Operation is possible. The swinging angle of the movable base 29 about the axis C3 by this leveling operation swings 10 ° to 20 ° to one side when the movable base 29 is horizontal with respect to the frame 28 (the state shown in FIG. 3). And can swing 10 ° to 20 ° to the other.

Further, according to the rolling drive mechanism 32, the first support member 26 can be rotated with respect to the second support member 27, and a rolling operation for rotating the first and second treatment elements with respect to the user is performed. It becomes possible. Therefore, this massage machine 7 can move the treatment element in various directions. Further, the rotation of the movable base 29 around the axis C1 by the rolling drive mechanism 32 is unidirectional when the axis C3 and the movement direction of the massage unit 8 are parallel to each other (state shown in FIG. 3). It can be rotated 180 ° and can be rotated 180 ° in the other direction.
Then, the leveling drive mechanism 31 and the rolling drive mechanism 32 can operate under the control of the control means 10 as shown in FIG. That is, the control means 10 can give an operation signal to each of the motors 33 and 36 included in the leveling drive mechanism 31 and the rolling drive mechanism 32.

The leveling drive mechanism 31 and the rolling drive mechanism 32 drive the movable base 29 so that the position of the movable base 29 is changed with respect to the frame 28 of the massage unit 8. A plurality of treatment elements are mounted on the movable base 29. As described above, these treatment elements can be massaged by pinching and kneading.
Therefore, the assembly structure of the first drive mechanism 11 as the stagnation drive mechanism that causes massage treatment by pinching between the treatment elements and the movable base 29 will be described. The first drive mechanism 11 is fixed to the movable base 29. .

Specifically, as shown in FIGS. 5 and 6, the motor 41 (geared motor) included in the first drive mechanism 11 is an annular mounting member 40 a that protrudes from the back surface of the movable base 29. The rotating shaft 42 provided in the first drive mechanism 11 is supported at both ends rotatably by mounting members 40b and 40c that protrude from the back surface of the movable base 29.
As a result, the movable base 29 on which the first and second treatment elements are mounted swings or rotates together with the first support member 26, but the first drive mechanism 11 is fixed to the movable base 29. Therefore, the first drive mechanism 11 can perform these operations together with the movable base 29.

The assembly structure of the second drive mechanism 12 as a rotational drive mechanism that causes the second treatment element 2 to perform massage motion by kneading and the movable base 29 will be described. Similarly, the second drive mechanism 12 is connected to the movable base 29. It is fixed.
Specifically, as shown in FIGS. 5 and 6, the motor 46 (geared motor) included in the second drive mechanism 12 is an annular mounting member 40 b protruding from the back surface of the movable base 29. The rotary shaft 47 provided in the second drive mechanism 11 is supported at both ends rotatably by mounting members 40c and 40d that protrude from the back surface of the movable base 29. Thereby, the second drive mechanism 11 can swing and rotate with the movable base 29.

And as a function which the said rolling drive mechanism 32 has, there exists a function which makes the 1st treatment elements 1a and 1b and the 2nd treatment element 2 which are mounted in the base part 21 perform rolling massage. 3 includes a movable base 29 and a first support member 26 that supports the movable base 29.
The rolling drive mechanism 32 continuously moves the base portion 21 around an axis C1 that passes through the rotation center of the base portion 21 between both treatment elements and faces the base portion 21. By rotating, it is possible to cause the user to perform a rolling massage that rotates both treatment elements around the axis C1. That is, it can be realized by continuously rotating the motor 33. The base portion 21 can be rotationally driven in one direction (clockwise direction) or in the other direction (counterclockwise direction). Further, the direction of these directions is alternately switched by the action of the control means 10, and a rolling massage is performed. May be performed.

In addition, as another function of the rolling drive mechanism 32, the first and second treatment elements approach each other by rotating the base portion 21 around the axis C1 facing in the direction penetrating the base portion 21. Alternatively, there is a function as an angle adjusting mechanism 14 that adjusts the sandwiching direction of separation.
This angle adjustment mechanism 14 can change the pinching direction by both the first treatment element 1a, 1b and the second treatment element 2 by rotating the base portion 21 about a predetermined angle around the axis C1. It can be adjusted in a desired direction.
That is, it can be realized by rotating the motor 33 and rotating the base portion 21 in one direction or the other direction by a predetermined angle. The rotation angle and rotation direction of the base portion 21 are controlled by a control signal from the control means 10.

Further, as other operations performed by the massage machine 7, there are further two operations of swinging the movable base 29 on which the treatment element is mounted with respect to the frame 28 of the massage unit 8.
Specifically, in FIG. 3, the second support member 27 supporting the movable base 29 via the first support member 26 is changed to the first frame 28 a of the frame 28 by the arm portion 27 a. The shaft 28 is supported so as to be swingable around a straight axis C4 from the frame 28 side to the user side. A driving means (not shown) for driving the second support member 27 to swing with respect to the first frame 28 a is mounted on the massage unit 8. Thereby, the massage machine 7 can be swung (turned) in a direction straddling a virtual straight line in the moving direction of the massage unit 8. Accordingly, the massage position can be changed by displacing the massage machine 7 without changing the position of the frame 28 of the massage unit 8. Note that this swing angle can be swung from 20 ° to 40 ° in one direction, based on the state where the axis C3 and the moving direction of the massage unit 8 are parallel (state of FIG. 3). It can be swung in the other direction by 20 ° to 40 °.

  Further, the first frame 28a is supported by the second frame 28b to which the roller 30 is attached so as to be swingable about the axis C5. The axis C5 is set to a direction orthogonal to an imaginary straight line that is a moving direction of the axis C4 and the massage unit 8. A driving means (not shown) for driving the first frame 28 a to swing with respect to the second frame 28 b is mounted on the massage unit 8. Thereby, the base part 21 which mounts the 1st and 2nd treatment element can be made to approach or leave | separate with respect to a to-be-treated person, and the press degree with respect to the to-be-treated person of the said 1st and 2nd treatment element is adjusted. can do. That is, the acupressure adjusting mechanism 15 can be configured thereby. It should be noted that the swing angle of both treatment elements by the finger pressure adjusting mechanism 15 is in the push-out direction (the person to be treated) when the movable base 29 is horizontal with respect to the frame 28 (the state shown in FIG. 3). It can swing 20 ° -40 °.

  According to the massage unit 8 equipped with the massage machine 7 configured as described above, the first and second treatment elements can be made to perform complicated massage operations while being compact. Furthermore, the suitable massage approximated by the massage by a human hand can be performed by arrangement | positioning of the treatment element by this invention, and its operation | movement. And in the backrest part 4 of a chair type massage machine (refer FIG. 1 and FIG. 2), the massage machine 7 can be operated variously, moving the massage unit 8 up and down in the height direction of a user.

Next, a second embodiment of the massage machine of the present invention will be described.
FIG. 10 is a perspective view showing an embodiment of the massage machine (second embodiment) of the present invention, and FIG. 11 is a perspective view showing the main part thereof. FIG. 12 is a sectional side view of the massage machine. And this massage machine is mounted in the massage unit similar to the massage unit 8 shown in FIG. 3 (illustration omitted).
The overall configuration of the massage machine 57 will be described.
The massage machine 57 includes a treatment element (massage ball) for massaging the user and a drive mechanism for driving the treatment element. The treatment element of the present invention includes a plurality of first treatment elements and a smaller number of second treatment elements than the first treatment elements. In addition, the treatment element shown to the figure consists of the two 1st treatment elements 1a and 1b and the one 2nd treatment element 2. FIG.
And the massage machine 57 of this invention is provided with the stagnation drive mechanism 62 (refer FIG. 15) which makes these 1st treatment elements 1a and 1b and the 2nd treatment element 2 approach or separate from each other as said drive mechanism. FIG. 15 is a block diagram showing an outline of a mechanism provided in the massage machine 57 of the present invention.

  In FIG. 10 and FIG. 11, the two first treatment elements 1a and 1b are arranged side by side, and the second treatment element 2 is provided to face these first treatment elements 1a and 1b. . As a result, the stagnation drive mechanism 62 causes the first treatment elements 1a, 1b and the second treatment element 2 to move toward or away from each other, so that the first treatment elements 1a, 1b are other than the thumb of the human hand. The second treatment element 2 is regarded as a thumb while being regarded as a finger (forefinger and middle finger), and massage by pinching is possible by these three treatment elements. In other words, a suitable massage approximated by a massage by a human hand can be performed.

  Further, this massage machine 57 is a driving mechanism for driving the first and second treatment elements, and in FIG. 12, the first treatment elements 1a, 1b and the second treatment element 2 are rotated around the axis C1 (rotation axis). A rotation drive mechanism 61 is provided for rotation. Thereby, the 1st treatment element 1a, 1b and the 2nd treatment element 2 which were made to think of the finger of a person's hand can perform the rolling massage which rotates integrally with respect to a to-be-treated person. In addition, FIG. 13 shows a state in which these treatment elements are rotated by a predetermined angle (90 ° counterclockwise when the massage machine 57 is viewed in the axial direction from the user side) by the rotation drive mechanism 61 from the state of FIG. ing.

Furthermore, in FIG. 12, this massage machine 57 includes a first drive element 1a, 1b and a second treatment element 2 as a drive mechanism in addition to the stagnation drive mechanism (first drive mechanism) 62 that approaches or separates from each other. The two treatment elements 2 are provided with a rotation drive mechanism (second drive mechanism) 63 that drives so as to perform a more complicated massage motion other than this approach or separation. The complicated massage exercise to be performed on the second treatment element 2 by the rotation driving mechanism 63 can be a kneading operation that rotates the second treatment element 2 along a circular path with respect to the user (human body). . Specifically, the rotation driving mechanism 63 is configured to rotate the rotation shaft 70a to which the second treatment element 2 is attached about its axis (rotation axis) C2. According to this, the 2nd treatment element 2 made to look like the thumb of a person's hand can be massaged by the massage which draws a circular orbit with respect to a to-be-treated person. The axis C2 and the axis C1 of the rotation shaft 20a are parallel to each other.
In addition, the circular orbit of the second treatment element 2 has a case around an axis parallel to the reference axis C1 (axis) of the massage machine and a case around an inclined axis intersecting with the reference axis C1. As will be described later, this is because the center line of the bearing portion having the plurality of rolling elements 97 is inclined with respect to the axis C1 (axis C2). And when this circular orbit is made around an inclined axis, the distance of the second treatment element 2 to the body of the user can be changed, so the massage force (pressing force) by the second treatment element 2 is changed. Can be made.
In the above, the drive mechanism of the massage machine of the present invention includes the stagnation drive mechanism 62, the first treatment elements 1a, 1b, and the second treatment element 2 that move the first treatment elements 1a, 1b and the second treatment element 2 closer to or away from each other. And a rotation drive mechanism 61 that rotates the shaft 2 largely around the axis C1 and a rotation drive mechanism 63 that rotates the second treatment element 2 small.

Next, the said drive mechanism with which the massage machine of this invention is provided is demonstrated concretely.

Motors 91, 98, and 96 included in the first drive unit 81, the second drive unit 82, and the third drive unit 83 are fixed to the flange portion 76a.
Inside the fixed case 76, a rotary shaft 92 centered on the axis C1 is attached to the fixed case 76 so as to be rotatable. Further, a cylindrical rotating cylinder 93 is provided on the outer peripheral side of the rotating shaft 92 through a bearing so as to be rotatable. The rotary cylinder 93 is centered on the axis C1. The rotary base 77 is provided on the outer peripheral side of the rotary cylinder 93 so as to be rotatable through a bearing. The rotation base 77 is centered on the axis C1. Thereby, the rotation base 77 is in a state of being rotatably accommodated in the fixed case 76.

  The first drive means 81 has a gear portion 84 for rotating the rotary base 77 around the axis C1. The gear portion 84 includes a gear 84 a that is externally fitted and fixed to the small diameter portion 77 a of the rotation base 77, and a worm 84 b that meshes with the gear 84 a. Then, the rotational driving force from the motor 91 included in the first driving means 81 is transmitted to the worm 84b. Due to the rotation of the motor 91, the rotation base 77 can be driven to rotate around the axis C1. The power transmission between the motor 91 and the shaft (not shown) of the worm 84b is performed by a belt (see FIG. 10).

The drive cam 78 is fixed to the rotary cylinder 93 by external fitting. The drive cam 78 is a thick cylindrical member, and the end surface on the treatment element side is a cam surface 78a inclined with respect to the axis C1.
And the 2nd drive means 82 has the gear part 85 for moving the cam surface 78a of this drive cam 78 in and out of the axial center C1 direction. The gear portion 85 includes a gear 85a that is externally fitted and fixed to the rotary cylinder 93, and a worm 85b that meshes with the gear 85a. The rotational driving force from the motor 98 included in the second driving means 82 is transmitted to the worm 85b. The rotation of the motor 98 causes the rotary cylinder 93 to rotate via the gear portion 85, and the drive cam 78 rotates about the axis C1 together with the rotary cylinder 93. As a result, the cam surface 78a of the drive cam 78 can be moved back and forth in the direction of the axis C1. The power transmission between the motor 98 and the shaft (not shown) of the worm 85b is performed by a belt (see FIG. 10).

  The driven cam 80 is provided adjacent to the cam surface 78 a of the drive cam 78. The driven cam 80 has a thick cylindrical portion 80a and an arm portion 80b continuously extending from the cylindrical portion 80a to the treatment element side. The cylindrical portion 80a is movable in the direction of the axis C1 and is fitted on the rotating cylinder 93. The driven cam 80 is restricted in the rotational direction. The end surface of the driven cam 80 on the drive cam 78 side is a cam surface 80 c that contacts the cam surface 78 a of the drive cam 78. The cam surface 80c is also a surface inclined with respect to the axis C1. The arm portion 80 b of the driven cam 80 is a bar member extending toward the treatment element side, and is connected and fixed to the moving base 89. As a result, the moving base 89 can move forward and backward in the direction of the axis C <b> 1 with respect to the rotating base 77 together with the driven cam 80.

  As the second drive means 82 is driven, the cam surface 78a of the drive cam 78 moves back and forth in the direction of the axis C1. Thus, the driven cam 80 is driven to advance and retract in the direction of the axis C1 through the engagement with the cam surface 78a of the drive cam 78, and the driven cam 80 can advance and retract the movement base 89 in the direction of the axis C1. it can. The moving base 89 is farthest from the rotating base 77 in a state where the top of the cam surface 78 a of the drive cam 78 is in contact with the top of the cam surface 80 c of the driven cam 80. Further, the moving base 89 is closest to the rotating base 77 in a state where the top of the cam surface 78 a of the drive cam 78 is in contact with the lower portion of the cam surface 80 c of the driven cam 80.

In FIG. 12, the rotation shaft 70a is attached to the rotation base 77 so as to be rotatable about its axis C2 through a bearing in the rotation base 77, and is attached to the rotation base 77 with its movement in the axis C2 direction regulated. ing. The rotation shaft 70 a is located on the outer peripheral side of the drive cam 78.
And the 3rd drive means 83 has the 1st gear part 86 and the 2nd gear part 87 for rotating the autorotation shaft 70a to the surroundings of the shaft center C2. The first gear portion 86 is provided on one end side that is the treatment element side of the rotation shaft 92, and the second gear portion 87 is provided on the other end portion side of the rotation shaft 93.

  The first gear portion 86 includes a gear 86a that is externally fixed to the rotary shaft 92, and a gear 86b that meshes with the gear 86a and is externally fixed to the rotation shaft 70a. The second gear portion 87 includes a gear 87a that is externally fixed to the rotary shaft 92, and a worm 87b that meshes with the gear 87a. The rotational driving force from the motor 96 included in the third driving means 83 is transmitted to the worm 87b. Due to the rotation of the motor 96, the rotation shaft 92 rotates around the axis C1 via the second gear portion 87, and the rotation shaft 70a can rotate around the axis C2 via the first gear portion 86. Further, the rotation driving of the rotation shaft 70a is possible even when the rotation base 77 rotates around the axis C1. The power transmission between the motor 96 and the shaft (not shown) of the worm 87b is performed by a belt (see FIG. 10).

In FIG. 13, the massage machine 57 further includes two fixed shafts 70 b that extend in the direction of the axis C <b> 1 and are fixed to the rotation base 77.
That is, the rotation base 77 includes an annular intermediate bottom wall portion 77b in a direction orthogonal to the axis C1, and a cylindrical small diameter portion 77a disposed so as to sandwich the intermediate bottom wall portion 77b and a cylindrical large size. A total of three fixed shafts 70b and one rotation shaft 70a projecting from the intermediate bottom wall 77b in the direction of the axis C1. Yes. The number of these projecting members corresponds to the number of treatment elements. Further, the projecting members (fixed shaft 70b and rotation shaft 70a) are straight cylindrical members, the base end side of which is attached to the rotation base 77, and the moving base 39 passes through the tip end side. . That is, the rotation base 77 is a base member to which these protruding members are attached as a unit.

  Then, one of the first treatment elements 1a and 1b and the second treatment element 2 is pivotally attached to the distal end side of these protruding members so as to be swingable. Specifically, the first treatment elements 1a and 1b are pivotally attached to the two fixed shafts 70b, and the second treatment element 2 is pivotally attached to the single rotation shaft 70a. Thereby, the protrusion direction of a protrusion member is made into the direction which goes to the user side. Further, the protruding direction (axial center direction) is a direction perpendicular to the surface of the intermediate bottom wall portion 77b of the rotation base 77, that is, a normal direction (axial center C1 direction) of the intermediate bottom wall portion 77b. The direction is parallel.

  In FIG. 12, the pair of first treatment elements 1a and 1b are respectively fixed to a first fixing member 67a. The fixing member 67a is pivotally attached via a pin 69 to an attachment portion 70d fixed to the distal end portion of the fixed shaft 70b. And the 2nd treatment element 2 is being fixed to the 2nd fixing member 67b. The fixing member 67b is pivotally attached via a pin 75 to a mounting portion 70c fixed to the tip end portion of the rotation shaft 70a.

The plate-like (flat plate-like) moving base 89 is provided between the rotary base 77 and the plurality of treatment elements so as to be able to advance and retreat, and is driven in that direction. The advancing / retreating drive direction of the moving base 89 is a direction parallel to the axis C1.
The rotation shaft 70a and the fixed shaft 70b penetrate the moving base 89 in the plate thickness direction. The moving base 89 can be configured to smoothly move linearly while being guided by the rotation shaft 70a and the fixed shaft 70b.

In FIG. 11, the massage machine 57 further includes link members 72a provided between the moving base 89 and the second treatment element 2 and between the movement base 89 and the first treatment elements 1a and 1b. , 72b.
Specifically, on the first treatment element 1a, 1b side, a pair of link members 72b are provided across one first treatment element (fixing member 67a), and each is a linear member. One end portion of the link member 72b is pivotally attached to the outer edge portion of the moving base 89 via a pin 94, and the other end portion fixes the first treatment elements 1a and 1b. It is pivotally attached to 67a through a pin 68 so as to be swingable.

  Further, on the second treatment element 2 side, a pair of link members 72a are provided with the second treatment element 2 (fixing member 72a) in between, and each is a linear member. One end of the link member 72a is pivotally attached to the moving base 89 via a pin 95, and the other end is fixed to the fixing member 67b that fixes the second treatment element 2 to the pin 74. It is pivotally attached via the via. The link member 72 a is pivotally attached to a rotation link 73 described later, and the link member 72 a is swingable with respect to the moving base 89 via the rotation link 73.

  As described above, the fixing members 67a and 67b that respectively fix the first and second treatment elements are the fixed shaft 70b and the rotation shaft 70a as the protruding members that protrude from the rotation base 77 toward the user. The link members 72b and 72a on the side of the moving base 89 that is driven forward and backward are also pivotally mounted.

  11 and 12, the second treatment element 2 attached to the tip end side can be rotated about the axis C2 by rotating about the axis C2 of the rotation axis 70a. Therefore, in order to rotate the second treatment element 2 around the axis C2, a rotation link 73 is provided on the moving base 89, and the link member 72a is pivoted on the rotation link 73. It is worn. And the 2nd treatment element 2 and the autorotation shaft 70a rotate with the rotation link 73 and the link member 72a. That is, the rotary link 73 moves forward and backward with the moving base 89, but is connected to the moving base 89 so as to be rotatable relative to the moving base 89 about the axis C2 side.

The rotating link 73 will be further described with reference to FIG.
On the moving base 89, an annular member 89b is provided by being fitted around the rotation shaft 70a. The rotation shaft 70a is rotatable with respect to the annular member 89b. The rotary link 73 includes an attachment portion 73a that is rotatably provided on the annular member 89 via a rolling element (cylindrical roller) 97, and a pivot attachment portion 73b that is pivotally attached to the link member 72a. is doing. That is, the attachment portion 73a of the rotary link 73 is rotatably supported with respect to the annular member 89b on the moving base 89 side. And the 2nd treatment element 2 (fixed member 67b) pivotally attached to the autorotation shaft 70a and the pivot attachment part 73b of the rotation link 73 provided on the movement base 89 are interlockingly connected by the link member 72a. .

  According to this, the rotation link 73 connected to the rotation shaft 70 a via the fixing member 67 b fixing the second treatment element 2 and the link member 72 a can be rotated relative to the moving base 89. Configured as follows. For this reason, the autorotation shaft 70a can autorotate around the axis C2. Accordingly, the rotation shaft 70a pivotally attached to the second treatment element 2 can be rotated by the driving of the third drive means 83, and the second treatment element 2 rotates around the axis C2 to be treated. Massage can be performed on the person.

Further, the movement base 89 is driven forward and backward by the drive of the second drive means 82, and the rotary link 73 moves forward and backward together with the movement base 89. Since the fixing member 67b that fixes the second treatment element 2 and the rotation link 73 that moves forward and backward are linked and connected by the link member 72a, the second treatment element 2 is pivotally attached to the rotation axis 70a ( It can be swung around the pin 75). Further, since the moving base 89 and the fixing member 67a that fixes the first treatment elements 1a and 1b are interlocked and connected by the link member 72b by the advance and retreat driving of the movement base 89, the first treatment element 1a. , 1b can be swung around a pivot axis (pin 69) with the fixed shaft 70b.
Thereby, the 1st treatment element 1a, 1b and the 2nd treatment element 2 can perform massage by pinching with respect to a user.

  Further, the attachment portion 73a of the rotation link 73 is not configured to rotate on a surface orthogonal to the axis C2 with respect to the annular member 89b on the moving base 89 side, and is formed on a surface orthogonal to the axis C2. It is set as the structure rotated on the surface inclined with respect to it. Therefore, the rotation link 73 rotates along a plane inclined with respect to the axis C2. Accordingly, the rotation of the rotation shaft 70a changes the distance between the second treatment element 2 and the rotation base 77 while rotating the second treatment element 2 about the axis C2. The contact strength with respect to the user by the treatment element 2 changes.

As described above, the rotation drive mechanism 63 of the massage machine has the rotation shaft that rotates around the axis C1 by driving the third drive means 83 and the second gear portion 87 of the third drive means 83. 92, a rotation shaft 70a that is rotatable about the axis C2, and a first gear portion 86 of third drive means 83 that transmits rotational power from the rotation shaft 92 to the rotation shaft 70a. ing. According to the rotation driving mechanism 63, the rotation shaft 70a can be rotated, and the second treatment element 2 attached to the tip end side of the rotation shaft 70a can be rotated around the axis C2. Thereby, the 2nd treatment element 2 can perform the massage operation by massage.
Since this kneading operation is obtained from the movement performed by the rotation of the rotation axis 70a around the axis C2, the structure for causing the second treatment element 2 to perform the kneading operation can be simplified.

  The massage driving mechanism 62 of the massage machine includes a second driving means 82, a rotating cylinder 93 that rotates around the axis C1 by driving the gear portion 85 of the second driving means 82, and A driving cam 78 that rotates together with the rotary cylinder 93 to move the cam surface 78a back and forth, a driven cam 80 that moves back and forth in the direction of the axis C1 in accordance with the driving cam 78, and a driven cam 80 that is connected to the driven cam 80. The moving base 89 is configured to move linearly, and link members 72a and 72b that convert the linear movement of the moving base 89 into the swinging motion of the first and second treatment elements. The first and second treatment elements can be swung by the kneading drive mechanism 62 so as to approach or separate from each other, and the first and second treatment elements can be massaged by pinching.

  Furthermore, according to this squeezing drive mechanism 62, a plurality of treatment elements can be simultaneously swung by advancing and retreating of one moving base 89, and massage by pinching squeezing can be performed by these treatment elements. Further, since the forward / backward movement of the moving base 89 is converted into the swing motion of each treatment element via the link members 72a, 72b, the direction of the swing axis of each treatment element (fixing member 67a, 67b) is changed. By doing so, the swinging direction of each treatment element can be set arbitrarily and easily. Furthermore, even if the number of treatment elements is increased from three, power can be obtained from one common moving base 89, so that the structure can be simplified even if the number of treatment elements increases.

The rotary drive mechanism 61 of the massage machine includes a first drive unit 81. According to the rotary drive mechanism 61, the gear 84 of the first drive unit 81 By driving, the rotation base 77 can be rotated about the axis C <b> 1 with respect to the fixed case 76. Then, by rotating the rotation base 77, the fixed shaft 70b fixed to the rotation base 77 and the rotation shaft 70a provided so as to be rotatable with respect to the fixed base 77 are rotated around the axis C1. be able to. That is, the first treatment elements 1a and 1b pivotally attached to the fixed shaft 70b and the second treatment element 2 pivotally attached to the rotation shaft 70a rotate around the axis C1 with respect to the fixed case 76. Thereby, the massage by rolling is performed by the 1st and 2nd treatment element.
Further, the rotation drive mechanism 61 rotates the rotation base 77 around the axis C1 by rotating 360 ° clockwise or counterclockwise, and continuously or rotating it by a predetermined angle clockwise. It can be rotated by a predetermined angle in the counterclockwise direction, and this can be repeated.

The massage exercise by pinching performed by the massage machine 57 will be further described. FIG. 14 is a view of the treatment element viewed along the direction of the axis C1.
In FIG. 14, a plurality of first treatment elements 1a and 1b constitute a treatment element group, and the stagnation drive mechanism causes the treatment element group and the single second treatment element 2 to approach or separate from each other. In addition, the first treatment elements 1a and 1b in the treatment element group are driven so as to approach or separate from each other during the approach or separation movement. That is, the massage machine 57 is configured so that the treatment element group and the second treatment element 2 approach or separate from each other and the plurality of first treatment elements 1a and 1b approach or separate from each other. The swing direction of the child is set.
The 1st treatment element 1a, 1b and the 2nd treatment element 2 are arrange | positioned so that the said axial center C1 may be enclosed from the circumferential direction centering on the axial center C1, The 1st treatment element 1a, 1b and the 2nd treatment element 2 Is configured to be able to swing toward or away from the axis C1 side by swinging.

This will be described in detail with reference to FIGS. 12 and 14. In each fixing member 67a to which the first treatment elements 1a and 1b are attached, a pin 68 pivotally connecting the fixing member 67a and the link member 72b is provided. The pin 69 that pivotally attaches to the fixing member 67a and the fixed shaft 70b is located farther from the axis C1. The swing directions of the first treatment elements 1a and 1b are directions to approach or separate from the second treatment element 2.
Further, in the fixing member 67b to which the second treatment element 2 is attached, the pin 74 pivotally attaching the fixing member 67b and the link member 72a pivotally attaches the fixing member 67b and the rotation shaft 70a side. The pin 75 is located farther from the axis C1 than the pin 75. Then, the swinging direction of the second treatment element 2 is a direction that approaches or separates from the axis C1.
Further, when the treatment element is viewed along the direction of the axis C1 (FIG. 14), each of the first and second treatment elements is arranged on a plurality of straight lines extending radially from the axis C1. .

According to this configuration, when a treatment element group including a plurality of first treatment elements 1a and 1b and a single second treatment element 2 approach or separate from each other and perform pinching, the plurality of first treatment elements Since 1a and 1b also mutually approach or leave | separate, the massage by the suitable pinch massage approximated by the massage by a human hand with respect to a to-be-treated person can be performed.
Further, when the treatment element is viewed along the direction of the axis C1, the straight line in the operation direction of the first treatment element 1a and the straight line in the movement direction of the first treatment element 1b may be parallel.

Furthermore, this stagnation drive mechanism has a function of driving the second treatment element 2 so that the approaching or separating stroke is larger than the same stroke of the first treatment elements 1a and 1b. This can be realized by configuring the swing angle of the second treatment element 2 to be larger than the swing angle of the first treatment elements 1a and 1b. Specifically, in FIG. 12, the distance between the first pin 74 and the second pin 75 on the second treatment element 2 side is the same as the first pin 68 and the first pin on the first treatment element 1a, 1b side. It is set to be smaller than the distance between the second pin 69. Thereby, even if the advance / retreat stroke of the movement base 89 for swinging the first and second treatment elements is the same, the strokes of the first and second treatment elements are different.
As described above, the stroke of the second treatment element 2 that is regarded as a thumb is larger than the stroke of the first treatment elements 1a and 1b that are regarded as fingers other than the thumb, and the massage by the hand of the person performed by moving the thumb greatly. A closer massage feeling can be achieved.

  The first treatment elements 1a and 1b and the second treatment element 2 are kneading balls having the same shape and the same size. And each treatment element is made into the shape which has the part from which a curvature differs, respectively. And as shown in FIG. 14, 1st treatment element 1a, 1b and the 2nd treatment element 2 are arrange | positioned so that it may mutually oppose on both sides of the axial center C1. The first treatment element 1a, 1b and the second treatment element 2 are attached to the fixed shaft 70b and the rotation shaft 70a, respectively, with the front and back attachment directions with respect to the axis C being switched. That is, the first treatment element 1a, 1b and the second treatment element 2 have the same shape and the same size, but the first treatment element 1a, 1b and the second treatment element 2 in the basic state shown in FIG. And are attached such that the surfaces toward the axis C1 are different. In addition, the said basic state means the state in which the 2nd treatment element 2 exists in the position most distant from the axis C1 among the rotation positions of the 2nd treatment element 2 around the axis C2.

  According to this, since the 1st treatment element 1a, 1b and the 2nd treatment element 2 are arrange | positioned so that it may mutually oppose, when both treatment elements rock | fluctuate, it is pinched with respect to a to-be-treated person. Massage is performed. The first and second treatment elements are attached to the fixed shaft 70b and the rotation shaft 70a with the attachment directions of the front and back having portions having different curvatures being changed, and both treatment elements are regarded as the same kneading balls. However, the contact areas of the first and second treatment elements with respect to the user are different. Therefore, the first and second treatment elements can give different massage feelings. Furthermore, since the first and second treatment elements are the same kneading balls, the number of treatment elements is one and the cost can be reduced.

Furthermore, according to the squeezing drive mechanism and the rotation driving mechanism of the present invention, the first treatment element 1a, 1b and the second treatment element 2 perform a squeeze squeezing action to approach or separate from each other, and the second treatment element 2 More complicated massage movements other than approach or separation, that is, massage movement by kneading can be performed. Therefore, this massage machine 57 enables a variety of massages to the user.
Further, a rolling operation in which the first and second treatment elements are integrally rotated by the rotational drive mechanism while the squeezing operation and the kneading operation are sandwiched between the treatment elements by these drive mechanisms, or one of these operations is performed. This makes it possible to perform massages that are even more varied for the user.

  In addition, the massage machine 57 performs a normal squeezing operation that sandwiches the user by the approach or separation of the first treatment element 1a, 1b and the second treatment element 2, while the second treatment element 2 applies to the treatment person. Since the kneading motion can be performed, it is possible to perform a combined massage by the pinching motion and the kneading motion on the same affected part. In order for the massage machine 57 to cause the treatment element to perform this combined massage, the massage machine 57 simultaneously operates the stagnation drive mechanism (second drive means 82) and the rotation drive mechanism (third drive means 83). Control means 10 (refer to Drawing 15) is further provided.

For the pinching operation, the first treatment elements 1a and 1b and the second treatment element 2 have the same oscillation period, and the period is preferably set to 2 to 4 seconds. Moreover, it is preferable that the period of the kneading operation by the second treatment element 2, that is, the rotation period is set to 2 to 4 seconds.
Since both the pinching operation and the kneading operation performed with respect to the same affected part as the composite massage are both the itching operation, it is preferable to operate them with substantially the same cycle. Specifically, the period of both is preferably set to 2 to 4 seconds.

Further, in the rotation operation of the second treatment element 2 in the kneading operation, it is preferable that the diameter of the rotation locus centering on the rotation shaft 70a is set to about 50 mm to 60 mm. Further, a moving stroke when the second treatment element 2 is moved along the direction of the axis C2 by the rotary link 73 provided to be inclined and rotated with respect to the axis C2 of the rotation axis 70a. Is preferably set to about 5 mm to 10 mm.
Further, in the swinging operation of the first and second treatment elements in the pinching operation, the movement distance of the first and second treatment elements in the direction orthogonal to the axis C1 is preferably set to 15 mm to 25 mm. .

  Further, the rotation drive mechanism 61, the stagnation drive mechanism 62, and the rotation drive mechanism 63 provided in the present invention can be operated by the control of the control means 10, as shown in FIG. That is, the control means 10 includes a first drive means 81 that the rotation drive mechanism 61 has, a second drive means 82 that the stagnation drive mechanism 62 has, and a third that the rotation drive mechanism 63 has. An operation signal can be given to each of the driving means 83.

The function further provided in the rotation drive mechanism 63 will be described.
In FIG. 12, the rotation driving mechanism 63 is continuously driven as described above, whereby the second treatment element 2 is continuously rotated so that the user can be massaged. This rotation driving mechanism 63 As other functions, there is a function as a direction switching mechanism that changes a direction in which the second treatment element 2 approaches or separates from the first treatment elements 1a and 1b.

That is, this direction switching mechanism can change the direction in which the 2nd treatment element 2 approaches or leaves | separates by rotating the rotation axis | shaft 70a with which the 2nd treatment element 2 was attached to the front-end | tip part.
The operation of the second treatment element 2 by this direction switching mechanism will be specifically described. When the rotation shaft 70a is rotated counterclockwise by a predetermined angle θ around the axis C2 from the state of FIG. 2 is displaced to the position indicated by the dashed line. Thereby, the rocking | fluctuation direction of the 2nd treatment element 2 changes from the left-right direction which goes to the axial center C1 of FIG. 14 to the diagonal direction which goes to the 1st treatment element 1a side of one side (right side of FIG. 14). In this state, the rotation shaft 70a is stopped, and the massage driving mechanism 62 (second drive means 82) is operated to cause the first and second treatment elements to perform the massage operation so that different massage massage directions can be performed. It becomes possible.

  In this way, the rotation shaft 70a can be rotated by a predetermined angle by intermittently operating the direction switching mechanism. Therefore, the direction of the swing direction of the second treatment element 2 can be changed every moment, and the direction in which the second treatment element 2 approaches or separates from the first treatment elements 1a and 1b can be changed. Thereby, this massage machine 57 can perform massage which is rich in change for the user. Furthermore, by changing the direction in which the second treatment element 2 approaches or separates, the degree of pressing of the second treatment element 2 against the user can be slightly changed. Thereby, the suitable massage approximated by the massage by a human hand can be performed. By configuring the direction switching mechanism using the rotation shaft 70a, it is possible to switch the pinching direction with a simple structure.

  In FIG. 12 and FIG. 13, the function of the massage by rolling which the rotation drive mechanism 61 has is further demonstrated. The first treatment elements 1a and 1b and the second treatment element 2 are mounted on a rotation base 77 (base portion). And the rotation drive mechanism 61 can perform the rolling massage which rotates both treatment elements around the axis C1 with respect to a to-be-treated person by rotating this rotation base 77 continuously. That is, it can be realized by continuously driving the first driving means 81. The rotation base 77 can be driven to rotate in one direction (clockwise direction) or the other direction (counterclockwise direction), and these directions are switched alternately by the action of the control means 10 (FIG. 15). And a rolling massage may be performed.

In addition, as another function of the rotation drive mechanism 61, as the angle adjustment mechanism 64 that adjusts the pinching direction in which the first and second treatment elements approach or separate by rotating the rotation base 77, There is a function.
The angle adjusting mechanism 64 can change the sandwiching direction between the first treatment element 1a, 1b and the second treatment element 2 by rotating the rotation base 77 about the axis C1 at a predetermined angle. It can be adjusted in a desired direction. That is, it can be realized by driving the first driving means 81 and rotating the rotation base 77 in one direction or the other direction by a predetermined angle. The rotation angle and direction of the rotation base 77 are controlled by a control signal from the control means 10 (FIG. 15).

  Moreover, this massage machine 57 makes the rotation base 77 carrying the first and second treatment elements approach or separate from the person to be treated, thereby allowing the first and second treatment elements to be treated. It can be set as the structure further provided with the acupressure adjustment mechanism (not shown) which adjusts a press degree. Specifically, the massage machine 57 shown in FIG. 10 is mounted on the massage unit 8 (see FIG. 1), and although not shown, the entire massage machine 57 can freely approach or leave the user. It is attached to the massage unit 8 and includes a driving means for moving the massage machine 57 toward or away from the user. According to this, when the acupressure adjusting mechanism causes the massage machine 57 including the rotation base 77 to approach or separate from the user, both treatment elements on the rotation base 77 acupressure the user. In addition, the degree of pressing against the user can be adjusted.

  According to the drive mechanism for a massage machine configured as described above, the first and second treatment elements can be made to perform complicated massage operations while being compact. Further, the rotational movement of the rotary base 77, the forward / backward movement of the moving base 89 (swing of the treatment element), and the rotation of the rotation shaft 70a (rotation of the second treatment element 2) can be performed by a gear mechanism. The structure can be simplified. Furthermore, the suitable massage approximated by the massage by a human hand can be performed by arrangement | positioning of the treatment element by this invention, and its operation | movement. And in the backrest part 4 of a chair type massage machine (refer FIG. 1 and FIG. 2), the massage machine 57 can be operated variously, moving the massage unit 8 up and down in the height direction of a user.

In addition, the massage machine of this invention is not restricted to the form to show in figure, The thing of another form may be sufficient within the scope of this invention, and it is good also as three or more treatment elements. For example, the number of first treatment elements may be four, and a single second treatment element may be considered to be a five-finger person's hand.
Further, the chair type massage machine of the present invention is not limited to the form shown in FIGS. 1 and 2, and may have other forms within the scope of the present invention. For example, the backrest part 4 is in an upright state or rearward. It may be possible to swing in a state of being tilted, or the leg rest portion 5 may be swingable up and down. Or a thing without a leg mounting part may be sufficient. Further, a massage device (the massage machine 57) capable of performing massage on the user may be provided only on the backrest 4 or on the seat 3. Alternatively, the massage machine 57 may be capable of moving from the backrest part 4 to the seat part 3, or may be capable of moving to the leg rest part 5.
