Although not shown, a power transmission belt is provided between the output shaft of the motor 5b and the input shaft of the speed reducing portion 5d. The drive shaft 5a is driven to rotate about an axis C2 extending toward the user side by the rotation of the motor 5b. As will be described in detail later, the rotational power of the single drive shaft 5a is transmitted to both the first arm 11 and the second arm 12. That is, the treatment mechanism 1 includes a single drive means 5 for operating the first arm 11 and the second arm 12, and this drive means 5 has a single drive shaft 5a that is rotationally driven. It becomes the composition which is doing. A swing shaft 10 is attached to the body member 9. The shaft center C1 of the swing shaft 10 and the shaft center C2 of the drive shaft 5a are parallel to each other, and the swing shaft 10 is attached to the body member 9 so as to be rotatable around the shaft center C1. In FIG. 3, the swing shaft 10 is provided with a pin 10d at one end 10a, and a mounting member 10c is fixed to the other end 10b.

  3 and 5, the eccentric cam 7 includes a disk-shaped first member 7a that is fitted and fixed to one end portion 5c of the drive shaft 5a, and a bearing (rolling bearing) 14 on the outer peripheral side of the first member 7a. And a second member 7b having a substantially annular shape provided via the. The center line C4 of the first member 7a is parallel to the axis C2 of the drive shaft 5a but is eccentric. The second member 7b is rotatable with respect to the first member 7a around the center line C4 of the first member 7a. The 2nd member 7b has the attaching part 7c which protrudes from the annular-shaped part.

  3, 4, and 6, the first arm 11 includes a pair of opposing side wall members 15 a and 15 a and a connecting member 15 b that connects the side wall members 15 a and 15 a on the tip end side. The single first treatment element 3 is attached to the connecting member 15b. And the 1st arm 11 is rotatably attached by the pin 7d provided in the attaching part 7c of the eccentric cam 7 in the base end part 11b. Further, the first arm 11 is rotatably attached by a pin 10d provided at one end portion 10a of the swing shaft 10 in the middle portion 11c.

  The second arm 12 includes a pair of opposing side wall members 16a and 16a and a connecting member 16b that connects the side wall members 16a and 16a on the distal end side. A single member is connected to the connecting member 16b. A second treatment element 4 is attached. And the 2nd arm 12 is rotatably attached by the pin 10e provided in the attachment member 10c of the said rocking | fluctuation shaft 10 in the base end part 12b. And the 2nd treatment element 4 and the 1st treatment element 3 become the opposing arrangement | positioning.

  The link member 13 is a plate-like member, and is provided between the side wall member 15a of the first arm 11 and the side wall member 16a of the second arm 12 (see FIG. 6), and connects both the arms 11 and 12. It is a member. 3 and 4, one end portion 13a of the link member 13 is rotatably attached by another intermediate portion 11d of the first arm 11 and a pin 13c, and the other end portion 13b of the link member 13 is The middle part 12c of the second arm 12 and a pin 13d are rotatably attached.

With the above configuration, the first arm 11 and the second arm 12 connected by the link member 13 swing integrally around an axis (swing axis) C1 extending to the user side of the swing shaft 10. It becomes possible.
Further, the first arm 11 can rotate around the axis of the pin 10d (first stagnation axis C5), and the second arm 12 can rotate around the axis of the pin 10e (second stagnation axis C6). Can be rotated. The first stagnation axis C5 and the second stagnation axis C6 are parallel to each other, and the stagnation axes C5 and C6 are parallel to a virtual straight line (not shown) orthogonal to the swing axis C1. Then, when the first arm 11 is rotated about the first stagnation axis C5 and moved toward and away from the second arm 12, the link member 13 rotates the second arm 12 about the second stagnation axis C6. The first arm 11 can be moved closer to and away from the first arm 11. As a result, the first arm 11 and the second arm 12 can simultaneously move toward each other or simultaneously move away from each other, and the distal ends 11a and 12a of both arms 11 and 12 can be moved to each other. The attached treatment elements 3 and 4 are separated from each other.

  Therefore, when the drive shaft 5a of the drive means 5 rotates about the axis C2, as shown in FIGS. 5A to 5D, the second member 7b of the eccentric cam 7 does not rotate and the axis C2 does not rotate. Eccentric motion that revolves in a state of eccentricity around is generated. As shown in FIGS. 5A and 5C, this eccentric motion has a component that causes the second member 7b to reciprocate in the left-right direction in this figure. As shown in FIGS. 3 and 4, the first arm 11 and the second arm 12 are attached to a mounting portion 7 c in a part of the reciprocating second member 7 b. Since only one arm 11 is attached, the first arm 11 can be reciprocated around the first stagnation axis C5. As a result, as shown in FIGS. 6A and 6C, the treatment element 3 of the first arm 11 approaches or separates from the treatment element 4 of the second arm 12. The first arm 11 reciprocates around the first stagnation axis C5, whereby the second arm 12 can be reciprocated around the second stagnation axis C6 by the link member 13. Thereby, the treatment element 4 of the second arm 12 approaches or separates from the treatment element 3 of the first arm 11.

  Further, as shown in FIGS. 5A, 5B, 5C, and 5D, the second member 7b rotates in one direction around the axis C2 by the eccentric movement of the second member 7b of the eccentric cam 7. I have a circular movement. Since the first arm 11 is attached to the attachment portion 7c of the second member 7b performing the circular motion, the first arm 11 can be reciprocally swung around the swing axis C1. Accordingly, as shown in FIGS. 6A, 6B, 6C, and 6D, the treatment element 3 of the first arm 11 can be reciprocally swung around the swing axis C1. The first arm 11 reciprocally swings around the swing axis C1 so that the link member 13 can also swing the second arm 12 back and forth around the swing axis C1. Thereby, the treatment element 4 of the second arm 12 can be reciprocally swung around the swing axis C1. That is, the first arm 11 and the second arm 12 reciprocally swing integrally around the swing axis C1 in the same direction.

  That is, the eccentric cam 7 rotates the drive shaft 5a in a manner that causes the first arm 11 and the second arm 12 to swing about the swing axis C1 that extends toward the user side, It functions as a conversion member that converts the tip portions 11a, 12a with the two arms 12 into a movement that moves the two arms 12 closer to and away from each other.

  As described above, according to the treatment mechanism 1, the single drive shaft 5 a is driven to rotate by the single motor 5 b in the drive unit 5, so that the eccentric cam 7 and the treatment element 3 of the first arm 11. The movement of swinging the treatment element 4 of the second arm 12 around the swing axis C1 extending toward the user side and the movement of moving the treatment elements 3 and 4 closer to and away from each other in accordance with the swinging are performed simultaneously. Can do. As a result, the two treatment elements 3, 4 arranged facing each other with respect to the user's treatment part are moved away from each other, and at the same time, swing around the swing axis C <b> 1 extending toward the user side. "Massage" becomes possible. And since the structure which makes the both treatment elements 3 and 4 knead and pinch by the single drive means 5 is obtained, the treatment mechanism 1 can be reduced in size.

Furthermore, according to the link member 13, the single eccentric cam 7 operates the first arm 11, whereby the second arm 12 can be operated simultaneously. For this reason, the structure of the treatment mechanism 1 can be simplified and the treatment mechanism 1 can be reduced in size. Further, since the axis C2 of the drive shaft 5a and the swing axis C1 of the swing shaft 10 are parallel, the shaft center C2 and the swing axis C1 face the same direction. As a result, the eccentric cam 7 makes it easy to convert the rotational movement of the drive shaft 5 a into a swinging motion around the swinging axis C <b> 1 between the first arm 11 and the second arm 12. Simplification and miniaturization can be achieved.
And as shown in FIG. 1, in the backrest part 41 of this chair type massage machine, two massage units 44a and 44b are provided so that raising / lowering is possible, but the treatment mechanism 1 is reduced in size. Therefore, it becomes easy to provide two massage units 44 having the treatment mechanism 1 in the backrest portion 41.

  As shown in FIG. 2, the treatment mechanism 1 includes a treatment body portion 2, a first treatment element 3, a second treatment element 4, a first arm 11, a second arm 12, and a driving means. 5 and a link member 13. Furthermore, the treatment mechanism 1 includes a support member 17 to which the treatment main body 2 is attached. The support member 17 can swing around an axis C7 for changing the angle parallel to a virtual straight line (not shown) orthogonal to the swing axis C1 (see FIGS. 3 and 4). Is attached. The angle changing axis C7 is parallel to the first stagnation axis C5 and the second stagnation axis C6.

  The support member 17 includes a flat plate-like base end portion 17a on the rear side opposite to the treatment elements 3 and 4, and a pair of side wall portions 17b erected so as to face both edges of the base end portion 17a. , 17b and a base member 17c located further rearward than the base end portion 17a. The side wall portions 17b and 17b are arranged so as to sandwich the treatment body portion 2 (second arm 12). And the pin 18 is provided between the front-end | tip parts of the side wall parts 17b and 17b, and the treatment main-body part 2 is attached to this pin 18 so that rocking | swiveling around the axial center of the said pin 18 is possible. More specifically, a mounting portion 9 b is provided on the body member 9 of the driving means 5, and the treatment main body portion 2 is swingably attached by a pin 18 in the mounting portion 9 b. The axis of the pin 18 is the angle changing axis C7. As a result, the treatment body 2 is swingable about the axis C <b> 7 of the pin 18 with respect to the support member 17.

  And this treatment mechanism 1 is further provided with the angle adjustment means 26 which adjusts the angle of the treatment main-body part 2 centering on the axis C7 for angle change. The angle adjusting means 26 is provided on the support member 17 side together with the rack member 19 provided on the treatment main body 2 side, the tooth member 20 provided on the support member 17 side, and the tooth member 20 (the first member). ) Actuator 21. The rack member 19 is a member in which a plurality of teeth are continuously formed on the rear side of the body member 9. The rack member 19 has a plurality of teeth along a part (arc) of a circle centered on the axis C7 of the pin 18. It should be noted that the plurality of teeth of the rack member 19 may be provided on at least a part of a circle centered on the axis C7. On the other hand, the tooth member 20 is attached to the proximal end portion 17 a of the support member 17 and can mesh with the teeth of the rack member 19. The actuator 21 operates the tooth member 20.

  The tooth member 20 shown in FIG. 2 is provided in the base end part 17a so that a position change is possible in the position which meshes with the rack member 19, and the position where the mesh is released. Then, the position of the tooth member 20 relative to the rack member 19 is changed by the actuator 21 attached to the support member 17. The actuator 21 can adopt various types. For example, as shown in FIG. 16, the actuator 21 is of a solenoid type that drives the protruding member 21a forward and backward, and the operating member 20a attached to the tooth member 20 is the actuator. It can be set as the structure which changes the position of the tooth member 20 by operating 21. FIG. Specifically, as shown in FIG. 16A, an elastic member (not shown) that applies elastic force in the direction of separating the tooth member 20 from the rack member 19 is provided together with the tooth member 20, and the actuator 21 does not operate. In this state, the protruding member 21a does not press the operating member 20a, and the tooth member 20 and the rack member 19 are separated from each other. Then, as shown in FIG. 16B, when the actuator 21 is operated and the protruding member 21a pushes the operating member 20a, the tooth member 20 is brought close to the rack member 19 against the elastic force of the elastic member, It is possible to switch to a state where both are engaged. In addition, although the actuator 21 can be attached to the side wall part 17b of the supporting member 17, the side wall part is abbreviate | omitted for description in this FIG.

  According to this, if the solenoid actuator 21 moves the tooth member 20 to release the engagement with the rack member 19, the treatment body 2 can freely swing around the axis C <b> 7 with respect to the support member 17. . Thereby, the angle of the treatment main-body part 2 can be changed and adjusted freely. In this case, the angle of the treatment main body 2 can be changed using another driving means (not shown). When the treatment body 2 is set to an arbitrary swing position (swing angle) with respect to the support member 17 and the actuator 21 is not functioned, the tooth member 20 can be engaged with the rack member 19 by the elastic member. it can. Thereby, the swinging of the treatment main body 2 with respect to the support member 17 can be restricted. Thus, by using the angle adjusting means 26, the angle of the treatment main body 2 can be adjusted around the axis C7, and the contact state (contact of the treatment elements 3 and 4 with the user's treatment portion) Angle) can be changed. If the actuator 21 is of the solenoid type, the position of the tooth member 20 can be changed quickly, and the treatment mechanism 1 can be downsized. The angle adjusting means 26 of this form switches between an unlocked state allowing the swinging of the treatment body part 2 relative to the support member 17 and a locked state restricting the swinging of the treatment body part 2 at a predetermined swinging position. It can function as a locking means.

  Further, as a modification of the tooth member 20, although not illustrated, a pinion that meshes with the rack member 19 can be used. In this case, the support member 17 is provided with drive means (motor with a speed reducer) for driving the pinion in the forward and reverse directions, and the treatment main body 2 having the rack member 19 is rotated by rotating the pinion by the rotation of the drive means. The pin 18 can be swung around the axis C7. Thereby, the treatment main-body part 2 can be changed and adjusted to arbitrary angles, and the treatment main-body part 2 can be hold | maintained to a predetermined angle by stopping a drive means and maintaining the state. Thereby, the contact state (contact angle) of the treatment elements 3 and 4 with respect to a user's to-be-treated part can be changed, and the treatment elements 3 and 4 can be made into a desired attitude | position.

  FIG. 7 is a side view of the treatment mechanism 1, and FIG. 8 is a rear view (rear view) of the treatment mechanism 1. The support member 17 of the treatment mechanism 1 is attached to the treatment main body 2 having the first arm 11 and the second arm 12 so as to be rotatable around a rotation axis C3 extending to the user side. The treatment mechanism 1 further includes a turning means 6 that drives the treatment main body 2 to turn around the rotation axis C3 in the support member 17. This will be specifically described. In the support member 17, the base member 17c has a base end portion 17a and side wall portions 17b and 17b attached to be rotatable about the rotation axis C3. In FIG. 8, the base end portion 17a protrudes rearward and has a shaft portion 22 centering on the rotation axis C3. The shaft portion 22 passes through a hole (not shown) formed in the base member 17c. ing. A first tooth member (gear member) 23 having a plurality of teeth formed along a part (arc) of a circle centered on the rotation axis C3 is attached to the shaft portion 22. The plurality of teeth of the first tooth member 23 need only be provided along at least a part of a circle centered on the rotation axis C3. Although not shown, the plurality of teeth may be provided over the entire circumference of the circle. Good. Thereby, both the treatment main-body part 2 currently supported by the base end part 17a and the side wall parts 17b and 17b of the support member 17, and the 1st tooth member 23 can be rotated around the rotating shaft center C3. The base member 17c is provided with a second tooth member (hereinafter referred to as a rack member) 24 that meshes with the first tooth member 23, and a (second) actuator 25 that operates the rack member 24. ing.

  The actuator 25 includes a motor 25a that is fixed to the base member 17c, a screw shaft 25b that is provided on the base member 17c and is driven to rotate forward and backward by forward and reverse rotation of the motor 25a, and a nut member 25c that is screwed to the screw shaft 25b. And have. A power transmission belt 25d is interposed between the output shaft of the motor 25a and the end of the screw shaft 25b. The base member 17c is provided with a guide portion (not shown) extending in a direction parallel to the screw shaft 25b, and the nut member 25c is guided to the guide portion. Therefore, the nut member 25c can linearly reciprocate along the screw shaft 25b by forward and reverse rotation of the screw shaft 25b. The rack member 24 is fixed to the nut member 25c. When the nut member 25c reciprocates linearly, the rack member 24 reciprocates linearly, and the first tooth member 23 that meshes with the rack member 24 and the shaft The portion 22 rotates about 90 ° around the rotation axis C3. As a result, the base end portion 17a and the side wall portions 17b and 17b of the support member 17 reciprocally rotate around the rotation axis C3, and the treatment main body 2 supported by the side wall portions 17b and 17b moves around the rotation axis C3. Can reciprocate. Thus, the turning means 6 can be configured to include the tooth member 23, the rack member 24, and the actuator 25.

According to this turning means 6, the first arm 11 and the second arm 12 can be moved by turning the treatment body 2 having the first arm 11 and the second arm 12 around the rotation axis C <b> 3. It is possible to change the direction of approaching and moving away from each other (the direction of pinching). That is, in FIG. 7, the approaching / separating direction between the first treatment element 3 and the second treatment element 4 is the left-right direction, but when the treatment body 2 is turned 90 °, the first treatment element 3 and the second treatment element 3 The approaching / separating direction from the treatment element 4 can be changed by 90 ° in FIG.
In this turning means 6, the turning angle can be set to 360 °. In this case, teeth may be formed on the entire circumference of the first tooth member 23 and the rack member 24 and the screw shaft 25b may be elongated.
Further, as a modification of the swiveling means 6, although not shown, a first tooth member 23 having a full circumference tooth and a gear having a full circumference tooth are used as a second tooth member meshing with the tooth member 23. The tooth member may be rotated by an actuator (motor with a speed reducer). In this case, the turning angle can be set to 0 ° to 360 ° or even 360 ° or more.

  Moreover, this massage machine is provided with the raising / lowering means (not shown) which raises / lowers the massage unit 44 (refer FIG. 1) provided with the said treatment mechanism 1. As shown in FIG. The massage unit 44 is movable up and down along the guide rails 31 constituting the guide passage 45 in the backrest part 41, and the lifting means lifts and lowers the massage unit 44. The elevating means includes a drive unit having a motor or the like, and the elevating means operates based on an operation signal from a control means provided in the chair type massage machine. In the form of FIG. 1, two massage units 44a and 44b are provided on the left and right, but each of these massage units 44a and 44b has lifting means. Thereby, each of massage unit 44a, 44b can be raised / lowered independently.

  FIG. 9 is a front view of the massage unit 44. Although various types of lifting means can be adopted, for example, as shown in FIG. 9, the lifting means 27 having a motor (not shown) is mounted on the frame 8 of the massage unit 44, so that the massage unit 44 is mounted. However, the guide passage 45 can be self-propelled. That is, in FIG. 9, a pair of upper and lower rollers 30 are rotatably attached to the left and right sides of the substantially rectangular frame 8, and these rollers 30 roll along the guide rails 31. Then, at least one of the four rollers 30 in total (two rollers 30a in FIG. 9) is rotationally driven by a motor (not shown) mounted on the frame 8. The massage unit 44 can move when the drive roller 30a drives the guide rail 31 to travel. In this case, it is preferable to form teeth on the outer peripheral surface of the drive roller 30a and to form a rack portion with which the teeth of the drive roller 30a mesh with the guide rail 31.

  Furthermore, each massage unit 44 is provided with the area | region change means 29 which can move the treatment mechanism 1 to the left-right direction, and can change the massage area of the left-right direction by the treatment elements 3 and 4. FIG. The region changing means 29 is a left-right moving means that can move the treatment mechanism 1 in the left-right direction with respect to the frame 8. It can be set as the structure which has the support member currently supported and the actuator which is guided to this support member and moves the treatment mechanism 1 in the left-right direction. The support member may be configured to move the treatment mechanism 1 straight in the left-right direction, or by swinging the treatment mechanism 1 about the axis extending to the user side in the left-right direction of the treatment mechanism 1. The position may be changed. This region changing means 29 can move the treatment mechanism 1 in the left-right direction based on the operation signal of the control means provided in the massage machine, and can change the position in the left-right direction of the treatment mechanism 1.

  With the above configuration, in each of the left and right massage units 44a and 44b, the treatment mechanism 1 can perform pinching (kneading pinching) in which the treatment portion is sandwiched between the treatment elements 3 and 4 disposed to face each other. . The angle adjusting means 26 can change the posture of the treatment elements 3 and 4 by changing the inclination angle of the treatment main body 2 in the treatment mechanism 1, and the turning means 6 turns the treatment main body 2. By doing so, the direction of the massage operation by the treatment elements 3 and 4 can be changed. Further, the region changing means 29 can change the massage target part to be massaged by the treatment elements 3 and 4 in the left-right direction by changing the position of the treatment mechanism 1 in the left-right direction. Moreover, the raising / lowering means 27 can raise / lower each of massage unit 44a, 44b which mounts this treatment mechanism 1 independently, and changes the massage object site | part to massage by the treatment element 3,4 about an up-down direction. be able to.

[Massage operation]
FIG. 15 is a block diagram of the chair type massage machine of the present invention. In each of the first massage unit 44a and the second massage unit 44b, a massage by massage between the treatment elements 3 and 4 and other massages to be described later are operation signals from the control means 28 provided in the chair type massage machine. Based on. That is, the control unit 28 controls the operations of the driving unit 5, the turning unit 6, the angle adjusting unit 26, the elevating unit 27, and the region changing unit 29. The control means 28 comprises a microcomputer and includes a storage unit (memory) that stores a program for executing predetermined functions. The control means 28 receives a command signal from the controller 32 operated by the user, and executes each function based on the command signal.

  As shown in FIG. 1, two massage units 44 a and 44 b each having a treatment mechanism 1 are provided on the backrest portion 41 so as to be movable up and down, and each of the massage units 44 a and 44 b is independent. Therefore, the positions of the two massage units 44a and 44b in the height direction can be made different from each other. Thereby, it becomes possible to massage different parts in the height direction (height direction) of the user. For example, based on the operation signal of the control means 28, the treatment mechanism 1 of the left first massage unit 44a performs massage by kneading the left waist of the user, and at the same time, the right second massage unit 44b. The treatment mechanism 1 can perform massage by kneading and pinching the right shoulder of the user.

  The first massage unit 44a on the left side is equipped with the first treatment mechanism 1, and as already described (see, for example, FIG. 7), the first treatment mechanism 1 includes the treatment element 3 and the treatment element 4. Treatment body 2 having a first arm 11, a second arm 12 and the like attached to the distal end, respectively, and a turn for turning the treatment body 2 about a left rotation axis C3 extending to the user side Means 6 are provided. And since the left turning means 6 can change the direction in which the treatment element 3 of the first arm 11 and the treatment element 4 of the second arm 12 approach each other, the operating direction of the left treatment elements 3 and 4 can be changed. It functions as first operation direction changing means for changing.

  Similarly, the second massage unit 44 b on the right side is equipped with the second treatment mechanism 1 having the same configuration as the first treatment mechanism 1. The second treatment mechanism 1 also includes a treatment body 2 and a turning means 6 for turning the treatment body 2 around the right rotation axis C3 extending to the user side. Since the right turning means 6 can change the direction in which the treatment element 3 of the first arm 11 and the treatment element 4 of the second arm 12 approach and separate from each other, the operating direction of the right treatment elements 3 and 4 can be changed. It functions as a second operation direction changing means to be changed.

  Thereby, in the left first treatment mechanism 1, the operation direction of the pair of treatment elements 3 and 4 on the left side can be changed by rotating the treatment body part 2 around the rotation axis C3 on the left side extending to the user side. Further, in the right second treatment mechanism 1, the operation direction of the pair of right treatment elements 3, 4 can be changed by rotating the treatment main body 2 around the right rotation axis C <b> 3 extending to the user side. The means 28 can arbitrarily set the operation directions of the treatment elements 3 and 4 on the left side and the right side, respectively.

  Then, according to the position where the left and right massage units 44a and 44b are lifted and lowered by the lifting and lowering means 27, the control means 28 has the first movement direction changing means (the turning means 6) on the left side and the second movement on the right side. By using the direction changing means (swivel means 6), the operation direction of the left pair of treatment elements 3, 4 and the operation direction of the right pair of treatment elements 3, 4 can be changed. The operation direction of the first treatment elements 3 and 4 can be made different from the operation direction of the right second treatment elements 3 and 4.

  This will be specifically described. The lifting / lowering means 27 of the first massage unit 44a can give the control means 28 information about the position of the first massage unit 44a in the height direction. Further, based on the operation signal from the control means 28, the elevating means 27 operates for a predetermined amount, and the first massage unit 44a can be controlled to a predetermined height position. Further, the actuator 25 (see FIG. 8) of the turning means 6 serving as the first movement direction changing means provides the control means 28 with information on the turning angle (turning position) of the treatment main body 2 around the rotation axis C3. Can be given. That is, the control means 28 knows information about the operation direction (pinching direction) of the treatment elements 3 and 4. Furthermore, based on the operation signal from the control means 28, this turning means 6 operates for a predetermined amount, and the treatment main body 2 can be controlled to have a predetermined turning angle. Similarly, also in the 2nd massage unit 44b, the control means 28 can control the raising / lowering means 27 and the turning means 6 of the said 2nd massage unit 44b. Such a configuration can be realized, for example, when the elevating means 27 and the turning actuator 25 are provided with a servo mechanism using a drive motor (not shown) as a servo motor.

  Thereby, even when the same massage operation (for example, kneading and squeezing) is performed in the first massage unit 44a on the left side and the second massage unit 44b on the right side, for example, the control means 28 can control the left and right massage units 44a and 44b. The operating direction of the left treatment elements 3 and 4 and the operation direction of the right treatment elements 3 and 4 can be changed according to the position where the elevating means 27 is moved up and down, and the operation directions of the two treatment elements 3 and 4 can be made different. it can. In addition, in each of the left and right massage units 44a and 44b, regarding the change in the operation direction for massage by the treatment elements 3 and 4, in addition to the change in the operation direction of kneading pinching, the operation directions of other massage operations to be described later You can also make changes.

  According to this, even when the same massage operation (for example, squeezing and pinching) is performed on the left side and the right side, the treatment element of each of the left and right body of the user is determined according to each part in the height direction. By changing the operation direction, the shape and orientation of the motion trajectory of the treatment elements 3 and 4 brought into contact with the left half body and the shape and orientation of the motion locus of the treatment elements 3 and 4 brought into contact with the right half body are changed. be able to. Thereby, the left treatment elements 3 and 4 can be operated in a direction suitable for each part of the user's left body in the height direction, and suitable for each part of the right body in the height direction. The right treatment elements 3 and 4 can be operated in the direction.

  And the direction of the muscle fiber is different between the left half and the right half of the user (symmetrical), and the direction of the muscle fiber is different at each part in the height direction. However, according to this chair type massage machine, in each of the left and right massage units 44 a and 44 b, the control means 28 uses the turning means 6, so that the massager 3 and 4 can perform massage at a target site. The treatment body part 2 can be rotated in accordance with the direction of the muscle fibers to change the operation direction of the treatment elements 3 and 4. Therefore, a massage with a high treatment effect can be performed on each of the right and left body portions in the height direction.

  For this massage, it is necessary to detect the body shape of the user seated on the chair type massage machine. This body shape can be detected by means of conventionally known shoulder position detection. Explaining this, in the backrest 41, the left and right massage units 44a, 44b are moved from top to bottom, thereby moving the treatment elements 3, 4 from top to bottom. And when any one of the treatment elements 3 and 4 hits a shoulder, the load which acts on one is detected, and the position where the load was detected is automatically detected as a shoulder position. This shoulder position is stored in a storage unit that the control means 28 has. Further, when the shoulder position is detected, the control means 28 can determine the position of the muscle of the user who performs the massage and the position of the acupoint based on the shoulder position. To explain this in a simple manner, the position distribution of muscles and acupuncture points on the user's body (back) vary depending on the body type (height), but the positions of the thoracic vertebrae, lumbar vertebrae, and sacral vertebrae even if the body type is different The position of the muscle and the acupoint position can be obtained with reference to. Therefore, if the positions of the user's thoracic vertebra, lumbar vertebra, and sacral vertebra are obtained, the position of the muscle and the acupoint position can be obtained accurately. The positions of the user's thoracic vertebrae, lumbar vertebrae, and sacral vertebrae can be estimated by calculating the shoulder positions, thereby calculating the muscle positions and the acupoint positions. And the memory | storage part of the control means 28 memorize | stores the position and each acupoint position of each muscle of the user who performed the shoulder position detection. A specific means for obtaining the acupoint position is disclosed in, for example, Japanese Patent Application Laid-Open No. 2003-52780. Further, by performing this shoulder position detection, an upper limit position and a lower limit position (effective for massage) for massage by the treatment elements 3 and 4 are set. This shoulder position can be detected by the control means 28 (according to a program stored in the control means 28).

  And the massage operation | movement performed by changing the operation | movement direction of the treatment elements 3 and 4 according to a user's muscle fiber direction is demonstrated concretely. The left massage unit 44a and the right massage unit 44b have the same configuration. Therefore, a massage operation performed in the left massage unit 44a will be described as a representative.

  As described above, the left massage unit 44 a has one treatment mechanism 1 and is provided in the backrest 41 so as to be moved up and down by the lifting means 27. The treatment mechanism 1 includes a treatment main body 2 having treatment elements 3 and 4 and drive means 5 for operating the treatment elements 3 and 4, and a rotation axis C3 extending the treatment main body 2 toward the user. And swivel means 6 for rotating around. And the control means 28 can change the operation direction of the treatment elements 3 and 4 by rotating the treatment main-body part 2 by the turning means 6 according to the position which lifted the massage unit 44a by the raising / lowering means 27. FIG. .

  In view of this, in the left massage unit 44a, a massage of pinching massage performed by changing the pinching direction of the massage elements 3 and 4 according to the lift position of the massage unit 44a will be described. The treatment main body 2 has a pair of treatment elements 3 and 4 disposed so as to face each other, and the pair of treatment elements 3 and 4 operate to approach and separate from each other as described above. That is, this treatment mechanism 1 has a pinching mechanism that moves the pair of treatment elements 3 and 4 closer to and away from each other as one of its functions. And the control means 28 rotates the treatment main body part 2 by the turning means 6 in accordance with the raising / lowering position of the massage unit 44a by the raising / lowering means 27, thereby pinching the pair of treatment elements 3, 4 by the pinching mechanism. The direction can be changed.

And FIG. 10 is explanatory drawing explaining the massage of pinch massage performed by changing the operation direction of the treatment elements 3 and 4 according to the raising / lowering position of the massage unit 44a in this way. The arrow shown in FIG. 10 has shown the pinching direction of the pinching by the treatment elements 3 and 4 of the treatment main-body part 2. FIG.
The direction of muscle fibers is different at each site in the height direction of the user. Therefore, the control means 28 uses the turning means 6 according to each position in the height direction of the massage unit 44a to change the direction of pinching the muscle. In other words, the control means 28 responds to each position in the height direction of the massage unit 44a so that the treatment elements 3 and 4 approach and separate in the direction intersecting (orthogonal) with the longitudinal direction of the muscle fibers. The pinching direction of the treatment elements 3 and 4 (treatment body part 2) is set. And the control means 28 is changing the pinching direction of the treatment elements 3 and 4, moving the massage unit 44a in order with respect to a user's back in an up-down direction.

  For example, in the region A on the left and right sides close to the spine, when the massage unit 44a is on the shoulder, one of the pair of treatment elements 3 and 4 is moved from the upper left to the lower right in the direction of the other treatment element 4. And the other treatment element 4 is moved closer to one treatment element 3 in the opposite direction from the lower right to the upper left. When the massage unit 44a is below the shoulder and at the lower back, one of the pair of treatment elements 3 and 4 is made to approach the other treatment element 4 in the direction from the upper right to the lower left, The operation of making the treatment element 4 approach one treatment element 3 in the other direction from the lower left to the upper right, which is the opposite, is performed. In this way, massage can be performed by changing the pinching direction of the pair of treatment elements 3 and 4 according to each part in the height direction of the user.

  Furthermore, since the massage unit 44a includes a region changing unit 29 that switches the massage region by the treatment mechanism 1 in the left-right direction, the region change unit 29 is positioned in the left-right direction of the treatment mechanism 1 on the left half of the user. Can be massaged by the treatment elements 3 and 4 also on the area on the right side and the area on the left side of the area A. For example, massage can be performed on a region immediately adjacent to the spine on the right side of the region A, and massage by pinching that causes the treatment elements 3 and 4 to move up and down in the vertical direction will be described later. However, it is preferable that the massage is rubbed in the vertical direction by the treatment elements 3 and 4. Massage can also be performed on a region closer to the side on the left side of region A.

Further, with respect to the shoulder portion, it is preferable to cause the treatment elements 3 and 4 to perform a pinching operation having an operation component in the front-rear direction by inclining the treatment body portion 2 using the angle adjusting means 26. That is, a massage in which the shoulder is sandwiched in the front-rear direction is preferable.
In addition, when massaging an area in the height direction of the user, the massaging unit 44a is moved vertically by the elevating means 27 more slowly than when moving other areas, and the massaging is performed carefully. Also good.
From the above, it is possible to perform pinching massage with a high therapeutic effect in each part.

Furthermore, this treatment mechanism 1 has a pressing mechanism that pushes the user's treatment portion with the treatment elements 3 and 4 as another function. This is because the treatment body 2 is tilted by using the angle adjusting means 26, and one of the pair of treatment elements 3 and 4 is positioned in front of the other (the user's treatment part side). A pressing mechanism that pushes the treatment part by the one treatment element can be performed by performing the operation of the pinching (kneading pinching) in a state where one is in contact with the treatment part.
As another form of the pressing mechanism, in the treatment mechanism 1, the treatment body 2 is tilted by driving the angle adjusting means 26, and one of the pair of treatment elements 3, 4 is placed in front of the other. By moving to (the user's treatment part side), it can be set as the press mechanism in which the said one treatment element contacts a treatment part and pushes a treatment part further. In this case, the configuration of the angle adjusting means 26 is not the illustrated form (FIG. 2), but the tooth member 20 is a pinion that meshes with the rack member 19, and the driving means (with a speed reducer) that drives the pinion to rotate forward and reverse. A motor is provided. The pinion is rotated by the rotation of the driving means, the treatment main body 2 having the rack member 19 is swung around the axis C7 of the pin 18, and one treatment element pushes the treatment portion.
And the control means 28 rotates the treatment main body part 2 by the turning means 6 according to the raising / lowering position of the massage unit 44a by the raising / lowering means 27 and the left / right position of the treatment mechanism 1 by the area changing means 29, thereby The direction in which 3 and 4 push the treatment area can be changed.

  And FIG. 11 is explanatory drawing explaining the massage of the press performed by changing the operation direction of the treatment elements 3 and 4 according to the raising / lowering position of the massage unit 44a. The arrow shown in FIG. 11 indicates the direction in which the treatment part is pushed by the treatment element 3 (the front side of the treatment element 4). As shown in FIG. 11, the elevating means 27 and the area changing means 29 cause the treatment element 3 in the front to correspond to the position of a predetermined treatment part, and the treatment element 3 is treated according to the position. The direction of pushing the part is changed by the turning means 6. For example, the pressing direction by the treatment element 3 can be a direction from the bottom to the top for a certain treatment part, and the pushing direction by the treatment element 3 can be a direction from the top to the bottom for other treatment parts. .

  Thus, massage can be performed by changing the pressing direction (acupressure direction) by the treatment element 3 in accordance with each part in the height direction of the user, and acupressure massage with a high therapeutic effect can be performed on each part. . The configuration of the pressing mechanism may be another form. For example, the treatment mechanism 1 includes a drive unit (not shown) that moves the treatment main body 2 to the user side with respect to the support member 17, and the treatment mechanism 1 It is good also as a structure which the treatment elements 3 and 4 push a treatment part by moving 1 to the user side.

  Further, the treatment mechanism 1 has a filer mechanism that rubs the user's treatment area with at least one of the treatment elements 3 and 4 as another function. In this state, at least one of the treatment elements 3, 4 is in contact with the treatment portion, and at least one of the elevating means 27, the turning means 6, the angle adjusting means 26, and the region changing means 29 functions. Thus, by moving the treatment element along the user's body, a treatment mechanism in which the treatment element rubs the treatment portion in a pseudo manner can be obtained. Alternatively, a surging mechanism in which at least one of the treatment elements 3 and 4 is brought into contact with the treatment portion, and the treatment piece rubs the treatment portion in a pseudo manner by performing a pinching operation (kneading pinching). It can be. When performing this rubbing massage, the direction in which the treatment element is operated is preferably a direction along the muscle fiber (the longitudinal direction thereof), that is, a direction parallel to the muscle fiber, and further, a direction from the center side in the lateral direction of the body toward the outside. It is preferable to rub.

  And the control means 28 changes the direction which the treatment element 3 rubs a to-be-treated part by rotating the treatment main-body part 2 by the turning means 6 according to the raising / lowering position of the massage unit 44a. In the same manner as in the case of the pressing mechanism, it is preferable to tilt the treatment main body 2 by using the angle adjusting means 26 and to move one of the pair of treatment elements 3 and 4 (treatment element 3). With the other side (the treatment element 4) positioned in front (the user's treatment part side) and the one treatment element 3 being in contact with the treatment part, the operation of the pinching (kneading pinching) is performed. Let it be done. Thereby, the treatment element 3 can rub a treatment part.

  And FIG. 12 is explanatory drawing explaining the massage of the rubbing performed by changing the operation direction of the treatment elements 3 and 4 according to the raising / lowering position of the massage unit 44a. The arrows shown in FIG. 12 indicate the direction in which the treatment part 3 is rubbed with the treatment element 3. As shown in FIG. 12, the treatment element 3 in the front is made to correspond to the position of a predetermined treatment part by the lifting means 27, and the direction in which the treatment element 3 rubs the treatment part according to the position is turned. Change according to 6. The rubbing direction by the treatment element 3 is preferably the direction from the inner side (spine side) to the left outer side along the muscle fibers. And since the direction of the muscle fiber is different in each part in the height direction of the user, the treatment body part 2 is rotated by the turning means 6 together with the change of the massage position (change of the height position of the massage unit 44a). The rubbing direction (the rubbing direction) of the treatment element is changed according to each part in the height direction of the user. In this way, massage can be performed by changing the rubbing direction by the treatment element 3 according to each part in the height direction of the user, and rubbing massage with a high therapeutic effect can be performed on each part.

  Further, the configuration of the file mechanism may be another form. As another form of the file mechanism, the treatment elements 3 and 4 of the treatment mechanism 1 are rollers that can roll with respect to the user's treatment portion. Therefore, in a state where at least one of the treatment elements 3 and 4 is in contact with the treatment portion, one or both of the region changing means 29 and the elevating means 27 intersect the axis C3 extending to the user side. By moving the treatment mechanism 1 along the surface (virtual surface) and rolling the treatment element 3 (4) made of a roller with respect to the treatment portion, this may be used as a suspension mechanism. In this case, it is preferable that one of the pair of treatment elements 3 and 4 be in front. And the control means 28 changes the rolling direction of the treatment element 3 which consists of a roller by rotating the treatment main-body part 2 by the turning means 6 according to the raising / lowering position of the massage unit 44a. According to this, the rolling direction of the treatment element 3 made of a roller is changed by rotating the treatment main body 2 around the rotation axis C3 according to each part along the height direction of the user, By operating the area changing means 29, the treatment element 3 can be rolled with respect to the treated portion. Therefore, it is possible to perform a massage that rubs the treatment area by changing the rolling direction of the treatment element 3 according to each part.

  Next, another massage performed using the function of the region changing means 29 will be described. FIG. 13 is an explanatory view of the guide passages 45a and 45b and the massage units 44a and 44b in the backrest portion 41 as viewed from the user side. In addition, in this figure, the user leaning on the backrest part 41 is shown with the dashed-dotted line. 1 and 13, the first massage unit 44a is provided in the left guide passage 45a, the second massage unit 44b is provided in the right guide passage 45b, and the guide passages 45a and 45b are It is provided so as to be divided into two in the left-right direction and to extend along the up-down direction.

  As shown in FIG. 13, the region changing means 29 provided in the second massage unit 44b in the right guide passage 45b causes the right treatment mechanism 1 to enter the left guide passage 45a and The massage area in the left-right direction by the treatment mechanism 1 is switched to the center in the left-right direction. Further, although not shown, the region changing means 29 provided in the first massage unit 44a in the left guide passage 45a causes the left treatment mechanism 1 to enter the right guide passage 45b side, thereby treating the treatment mechanism 1. The left and right massage area can be switched to the center in the left and right direction.

Step (for example, FIG. 11) or a massage step performed by changing the rubbing direction by the treatment elements 3 and 4 in accordance with each part in the height direction of the user on the left and right while raising and lowering the left and right massage units 44a and 44b, respectively ( For example, there is a program having FIG.

  Moreover, the control means 28 has a time change function which changes the time of the massage operation with respect to a certain treatment part during the massage operation. This is because the control means 28 can extend or shorten the time of the currently performed massage operation by the user operating the controller 32 during a certain massage operation. FIGS. 14A and 14B are explanatory diagrams for explaining this function. This explanatory drawing is a case where the treatment elements 3 and 4 are performing a pressure (acupressure) massage on the shoulder of the user, and the vertical axis of the graph indicates the acupressure massage force (acupressure pressure by the treatment element). The horizontal axis indicates the time of the massage operation.

In the normal massage program (step), the time of acupressure massage (one acupressure stroke by the treatment element) is set to t0 seconds, and the user operates the controller 32 during the acupressure massage (acupressure massage step). By doing so, the control means 28 can extend the time of this acupressure massage from time t0 to time t1, as shown in FIG. Thereby, when the user feels the massage comfortably, this time change can be functioned and the massage time can be extended.
