  As shown in FIGS. 3 to 15, a plurality of massage units 8 and 9 are provided in the height direction. In the present embodiment, the first massage unit 8 disposed relatively on the upper side and the second massage unit 9 disposed relatively on the lower side are provided in the backrest portion 3. Each of the massaging units 8 and 9 mainly supports the body frames 30 and 50 supported by the guide mechanism 3b so as to be lifted and lowered, the massaging mechanisms 31 and 51 having the treatment elements 34 and 54, and the massaging mechanisms 31 and 51 Links 32 and 52, advancing and retracting drive units 15 and 16 for advancing and retracting the massaging mechanisms 31 and 51 with respect to the treatment subject, and links for pivoting the body frames 30 and 50 and the support frames 32 and 52 in the longitudinal direction 33 and 53, and is comprised.

Hereinafter, the configuration of the upper first massage unit 8 will be described in detail.
As shown in FIGS. 4 to 8, the body frame 30 has a rear wall 30a, side walls 30b erected from the left and right sides of the rear wall 30a, a bottom wall 30c erected from the lower portion of the rear wall 30a, and An upper wall 30d erected from an upper portion of the wall 30a, and a box-like shape opened at the front side. Further, the rotation of the lifting motor 35 for lowering and lowering the first massage unit 8, the lifting shaft 36 extending in the left-right direction, and the rotation of the lifting motor 35 are reduced and transmitted to the lifting shaft 36 above the inside of the body frame 30. An elevator mechanism constituted by the reduction gear 37 is accommodated. The elevating shaft 36 is rotatably supported by the both side walls 30b. On the side wall 30b, a guide roller 38 and a pinion 39 attached to the elevating shaft 36 are provided at the top, and a guide roller 38 and a pinion 39 are provided at the bottom. The guide mechanism 3b is held between the pinion 39 and the guide roller 38, and when the elevating motor 35 is driven, the first massage unit 8 can move up and down along the height direction. Since the elevating mechanism is disposed above the first massaging unit 8, the treatment element 34 can be brought close to the treatment element 54 (upper treatment element 54 a) of the second massaging mechanism 51.

  The first massaging mechanism 31 has a pair of arms 40 supporting the massaging element 34 at the tip and a driving mechanism for driving the arm 40 to perform massage. The drive mechanism performs a tapping operation by alternately advancing and retracting the massaging shaft 41 that supports the arm 40 and causes the massaging elements 34 to move in the lateral direction as the massaging elements move close to each other. A tapping shaft 42, a massage motor 43 as a massage drive unit for driving the massaging shaft 41 and the tapping shaft 42, and a decelerator 44 for decelerating the rotation of the massage motor 43 and transmitting it to the massaging shaft 41 and the tapping shaft 42 Have. The drive mechanism is supported by a box-shaped frame 45. In the present embodiment, the treatment elements 34 of the first massage unit 8 are single in the vertical direction.

  As shown in FIG. 9A, the stagnation shaft 41 extends in the left-right direction, and inclined shafts 41a inclined with respect to the axial center 41b are provided on the left and right sides. The arm 40 is rotatably attached to the inclined shaft 41a via a bearing. The left and right tilt axes 41a are not parallel to each other, but are inclined so as to form a substantially C shape in front view. Further, the stagnation shaft 41 is provided with a width sensor 46 that detects the distance between the pair of treatment elements 34. As shown in FIG. 9B, the tapping shaft 42 is extended in the left-right direction, and an eccentric shaft 42a eccentric to the axis 42b is provided on both left and right sides. Further, as shown in FIG. 5, a connecting member 47 for connecting the tapping shaft 42 and the rear portion of the arm 40 is provided rotatably on the eccentric shaft 42a via a bearing. The phases of the left and right eccentric shafts 42a around the axis 42b of the tapping shaft 42 are different from each other.

  When the stagnation shaft 41 rotates, the arm 40 is three-dimensionally rotated while the rotation around the stagnation shaft 41 is restricted by the connection member 47. That is, as shown in FIG. 16, when the stagnation shaft 41 is continuously rotated in one direction, the treatment element 34 operates in a loop-like locus having at least left and right and vertical components, As 34, it moves to the left and right direction and approaches and separates. Thus, the massaging operation is performed. On the other hand, when the tapping shaft 42 rotates, the pair of arms 40 alternately advances and retracts with the kneading shaft 41 as a fulcrum by the vertical movement of the connecting member 47. A striking operation is performed in this manner. In the present embodiment, by providing a clutch on the tapping shaft 42 and reversing the single massaging motor 43, it is possible to switch the massaging operation / massaging operation, but separately the massaging motor 43 is provided for massaging The action and the striking action may be performed independently.

  The support frame 32 has a plate surface in the front-rear direction, and supports the first massage mechanism 31 by fixing the frame 45 to the front side. Between the main body frame 30 and the support frame 32, a forward / backward air cell 15 as a forward / backward drive unit that moves the first massaging mechanism 31 forward or backward with respect to the treatment site by expansion / contraction by air supply / exhaust from air unit 20 It is provided. Further, on the side of the support frame 32, a link 33 is provided which connects the main body frame 30 and the support frame 32 and swings in the longitudinal direction. The reason why the link 33 is disposed to the side of the support frame 32 is that the thickness in the front-rear direction of the massage unit 8 can be suppressed as compared with the case where the link 33 is disposed behind the support frame 32. The links 33 are juxtaposed in the front-rear direction, and have a first link portion 33a relatively disposed on the rear side, and a second link portion 33b relatively disposed on the front side. That is, the link 33 constitutes a four-bar link mechanism.

  As shown in FIGS. 7 and 8, the lengths of the first link portion 33a and the second link portion 33b are different. Specifically, the length of the first link portion 33a is greater than the length of the second link portion 33b. Is also set to be short. An upper portion of the first link portion 33a is pivotally supported by the side wall 30b of the main body frame 30 via the swing axis A1 in the vicinity of the elevation shaft 36, and a lower portion is pivotally supported at the upper portion of the support frame 32 through the pivot axis A2. It is done. An upper portion of the second link portion 33b is pivotally supported by the side wall 30b of the main body frame 30 via the swing axis A3 in the vicinity of the elevation shaft 36, and a lower portion is pivotally supported to the lower portion of the support frame 32 through the pivot axis A4. It is done. The swing axis A1 of the first link portion 33a is located slightly behind the swing axis A3 of the second link portion 33b. The first link portion 33a and the second link portion 33b are respectively formed by fitting the pivots A2 and A4 to the downwardly convex arc-shaped guide portions 30e and 30f (see FIG. 4) provided on the side wall 30b. , Its operation is guided. Further, as shown in FIG. 7 and FIG. 8, a reinforcing portion 48 is provided which connects and reinforces the first link portion 33 a and the second link portion 33 b at the connecting portion with the main body frame 30. As described above, the vicinity of the swinging shafts A1 and A3 of the link 33 to which the load is applied can be reinforced by the lifting shaft 36 and the reinforcing portion 48.

  The link 33 is positioned forward of the link with the support frame 32 in the state where the first massaging mechanism 31 is retracted most. That is, in the first link portion 33a, the swing axis A1 is positioned forward of the pivot axis A2, and in the second link portion 33b, the swing axis A3 is positioned forward of the pivot axis A4. Therefore, when the air cell 15 expands and contracts, the link 33 swings in a downward arc shape, so that the first massaging mechanism 31 moves forward and backward along a path parallel to the direction facing the treatment site. Can. Further, since the four-bar link mechanism is adopted, when the forward / backward air cell 15 expands from the state where the first massaging mechanism 31 is retracted most, the first link portion 33a pivots forward about the pivot axis A1. However, since the support frame 32 is pivoted forward and downward relative to the pivot A2 of the first link 33a by the second link 33b, which is longer than the first link 33a, the swing of the first massaging mechanism 31 And can be advanced and retracted in a locus close to parallel to the direction opposite to the treatment site.

  In addition, since the lengths of the first link portion 33a and the second link portion 33b are different from each other, even if the first link portion 33a and the second link portion 33b are provided close to each other in the front-rear direction The amount of advance can be secured, and the thickness in the front-rear direction of the first massage unit 8 can be suppressed. In addition, since the length of the first link 33a disposed on the rear side is relatively short, a sufficient amount of movement of the anteroposterior direction component can be obtained immediately after the start of advancing, with the state where the first massaging mechanism 31 retracts most. be able to. Further, in the process of advancing the first massaging mechanism 31, the first link portion 33a abuts on the second link portion 33b from behind, thereby restricting the advancement of the first massaging mechanism 31 at a predetermined front and rear position. That is, since the second link portion 33b functions as a stopper, it is not necessary to separately provide a stopper, and the number of parts can be reduced.

Hereinafter, the configuration of the lower second massage unit 9 will be described in detail.
As shown in FIGS. 9 to 15, the body frame 50 has a rear wall 50a, side walls 50b erected from the left and right sides of the rear wall 50a, a bottom wall 50c erected from the lower portion of the rear wall 50a, and An upper wall 50d erected from an upper portion of the wall 50a and a box-like shape opened at the front by the upper wall 50d. In the lower part inside the main body frame 50, the elevation motor 55 for raising and lowering the second massage unit 9, the elevation shaft 56 extending in the lateral direction, and the rotation of the elevation motor 55 are decelerated and transmitted to the elevation shaft 56. An elevating mechanism constituted by the speed reducer 57 is accommodated. The elevating shaft 56 is rotatably supported by the both side walls 50b. On the side wall 50b, a guide roller 58 and a pinion 59 attached to the elevating shaft 56 are provided at the lower portion, and a guide roller 58 and a pinion 59 are provided at the upper portion. The guide mechanism 3b is held between the pinion 59 and the guide roller 58, and the second massaging unit 9 can move up and down along the height direction when the elevating motor 55 is driven. Since the elevating mechanism is disposed below the second massaging unit 9, the treatment element 54 (upper treatment element 54a) can be brought close to the treatment element 34 of the first massaging mechanism 31.

  The 2nd massaging mechanism 51 has arm 60 which makes a right-and-left pair which supports treatment element 54 at the tip, and a drive mechanism which drives arm 60 and performs massage. The drive mechanism includes a massaging shaft 61 for supporting the arm 60 and causing the massaging elements 54 in the pair to move in the lateral direction so as to perform massaging operation, and a massage motor 63 as a massage driving unit for driving the massaging shaft 61; And a decelerator 64 for decelerating the rotation of the massage motor 63 and transmitting it to the massaging shaft 61. The drive mechanism is supported by a box-shaped frame 65. The arm 60 is formed in a V-shape in a side view, a relatively large diameter upper treatment element 54a is provided at the upper end thereof, and a relatively small diameter lower treatment element 54b is provided at the lower end thereof. ing. That is, unlike the first massage unit 8, two treatment elements 54 are provided in the vertical direction.

  As shown in FIG. 9A, the massaging shaft 61 has the same structure as the massaging shaft 41 of the first massaging mechanism 31, extends in the left-right direction, and is inclined with respect to the axis 61b on both the left and right sides. An inclined shaft 61a is provided. The arm 60 is rotatably attached to the inclined shaft 61a via a bearing. The left and right inclined axes 61a are not parallel to each other, but are inclined so as to form a substantially C shape in front view. As shown in FIG. 15, at the rear of the arm 60, a connecting member 67 having a ball joint at the rear end is provided to connect the arm 60 and the support frame 52. A groove 69 extending in the left-right direction is provided on the front side of the support frame 52, and the ball joint of the connecting member 67 is fitted in the groove 69. In addition, a width sensor 66 for detecting the distance between the massaging elements 54 is provided on the massaging shaft 61.

  When the stagnation shaft 61 rotates, the arm 60 is three-dimensionally rotated while the rotation around the stagnation shaft 61 is restricted by the connection member 67. That is, as shown in FIG. 16, when the stagnation shaft 61 is continuously rotated in one direction, the treatment element 54 operates by drawing a loop-like locus having at least left and right and vertical components. The left and right treatment elements 54 operate in the left and right direction, the lower treatment element 54b separates when the upper treatment element 54a approaches, and the lower treatment element 54b approaches when the upper treatment element 54a separates. Thus, the massaging operation is performed. In the present embodiment, the second massaging mechanism 51 is configured to perform only the massaging operation, but may be configured to be able to perform the tapping operation as well as the first massaging mechanism 31.

  The support frame 52 has a plate surface in the front-rear direction, and supports the second massage mechanism 51 by fixing the frame 65 on the front side. Between the main body frame 50 and the support frame 52, an advancing and retracting air cell 16 as an advancing and retracting drive unit which is expanded and contracted by air supply and exhaust of air from the air unit 20 to move the second massaging mechanism 51 to the treated portion It is provided. Further, on the side of the support frame 52, a link 53 is provided which connects the main body frame 50 and the support frame 52 and swings in the front-rear direction. The links 53 are juxtaposed in the front-rear direction, and have a first link portion 53a relatively disposed on the rear side and a second link portion 53b relatively disposed on the front side. That is, the links constitute a four-bar linkage.

  The lengths of the first link portion 53a and the second link portion 53b are different, and specifically, the length of the first link portion 53a is set to be shorter than the length of the second link portion 53b. . The lower part of the first link portion 53a is pivoted on the side wall 60b of the main body frame 60 via the pivot axis A5 in the vicinity of the lift shaft 56, and the upper portion is pivoted on the lower portion of the support frame 52 via the pivot axis A6. It is done. The lower portion of the second link portion 53b is pivoted on the side wall 60b of the main body frame 60 via the pivot axis A7 in the vicinity of the elevating shaft 56, and the upper portion is pivoted on the upper portion of the support frame 52 via the pivot axis A8. It is done. The swinging axis A5 of the first link portion 53a is located slightly behind the swinging axis A7 of the second link portion 53b. The first link portion 53a and the second link portion 53b are respectively formed by the pivots A6 and A8 being fitted on the upwardly convex arc-shaped guide portions 50e and 50f (see FIG. 10) provided on the side wall 50b. , Its operation is guided. Further, as shown in FIG. 13 and FIG. 14, a reinforcing portion 68 is provided which connects and reinforces the first link portion 53 a and the second link portion 53 b at the connecting portion with the main body frame 60. As described above, the vicinity of the swinging shafts A5 and A7 of the link 53 to which the load is applied can be reinforced by the raising and lowering shaft 56 and the reinforcing portion 68.

  In the link 53, the connection with the main body frame 60 is located forward of the connection with the support frame 62 in a state where the second massaging mechanism 51 is fully retracted. That is, in the first link portion 53a, the swing axis A5 is positioned forward of the pivot axis A6, and in the second link portion 53b, the swing axis A7 is positioned forward of the pivot axis A8. Therefore, when the air cell 16 is expanded and contracted, the link 53 swings in a convex arc shape by moving the second massage mechanism 51 forward and backward along a path parallel to the direction facing the treatment site. Can. Further, since the four-bar link mechanism is adopted, when the advancing and retracting air cell 16 expands from the state where the second massaging mechanism 51 is retracted most, the first link portion 53a pivots forward about the pivot axis A5. However, since the support frame 52 is pivotally supported by the second link portion 53b longer than the first link portion 53a in front of and above the pivot A6 of the first link portion 53a, the second massage mechanism 51 swings. And can be advanced and retracted in a locus close to parallel to the direction opposite to the treatment site.

  Further, since the lengths of the first link portion 53a and the second link portion 53b are different from each other, even if the first link portion 53a and the second link portion 53b are provided close to each other in the front-rear direction, sufficient The amount of advance can be secured, and the thickness of the second massage unit 9 in the front-rear direction can be suppressed. In addition, since the length of the first link 53a disposed on the rear side is relatively short, a sufficient amount of movement of the anteroposterior direction component is obtained immediately after the start of advancing, with the second massage mechanism 51 being at the most backward position as a starting point. be able to. Further, in the process of advancing the second massage mechanism 51, the first link portion 53a abuts on the second link portion 53b from behind, whereby the advancement of the second massage mechanism 51 is restricted at a predetermined front and rear position. That is, since the second link portion 53b functions as a stopper, it is not necessary to separately provide a stopper, and the number of parts can be reduced.

[Sensor configuration]
As shown in FIG. 2, the massage machine 1 has a sensor 70 that detects the relative position of the first massage unit 8 and the second massage unit 9. The sensor 70 will be described in detail below.

  As shown in FIG. 4, the bottom wall 30 c which is the lower part of the first massage unit 8 is provided with a magnet holder 73 attached with a magnet on one side in the left-right direction, and detects the proximity of the magnet on the other side in the left-right direction. A sub control unit 25 (see FIG. 2) electrically connected to the sensor unit 71 and the first sensor unit 71 is provided. On the other hand, as shown in FIG. 10, the upper wall 50d, which is the upper part of the second massage unit 9, is electrically connected to the second sensor unit 72 and the second sensor unit 72 that detect the proximity of the magnet on one side in the left-right direction. The sub control unit 26 (see FIG. 2) is provided, and a magnet holder 74 having a magnet attached to the other side in the left-right direction is provided. The sub control units 25 and 26 are electrically connected to the lifting motors 35 and 55, respectively, and can control the lifting and lowering of the massage units 8 and 9. In addition, the main control unit 24 is also electrically connected.

  The first sensor unit 71 substantially coincides with the magnet holder 74 provided in the second massage unit 9 at a position orthogonal to the vertical direction, and detects the proximity of the second massage unit 9 to the first massage unit 8. Can. On the other hand, the second sensor unit 72 substantially coincides with the position perpendicular to the magnet holder 73 provided in the first massage unit 8 in the vertical direction, and detects the proximity of the first massage unit 8 to the second massage unit 9 can do. That is, the sensor 70 is a non-contact type sensor composed of the first sensor unit 71 and the second sensor unit 72. As described above, each of the massage units 8 and 9 detects the proximity of the massage units 9 and 8 on the other side, and the sub control units 25 and 26 control the lift motors 33 and 55, respectively. Accuracy increases.

  In addition, it is preferable that the sensor 70 can detect the space | interval of both the massage units 8 and 9 in multiple steps as a relative position of the 1st massage unit 8 and the 2nd massage unit 9. FIG. For example, it may be possible to detect a two-step state of “proximity state” in which the distance between both massage units 8 and 9 approaches to a predetermined distance and “pre-proximity state” slightly separated from this proximity state. Therefore, the detection range of the relative position of the 1st massage unit 8 and the 2nd massage unit 9 spreads. Moreover, both massage units 8 and 9 can also be integrally raised / lowered in the state which maintained this relative position as a predetermined relative position (for example, proximity | contact state or proximity | contact prior state).

  As shown in FIG. 2, the backrest portion 3 includes an upper limit sensor 75 that detects the upper limit position of the lifting and lowering range of the first massage unit 8, and a lower limit sensor 76 that detects the lower limit position of the lifting and lowering range of the second massage unit 9. , And the first and second massage units 8 and 9 are not separated from the backrest 3. In addition, the first and second massage units 8 and 9 respectively include elevation sensors 77 and 78 that detect the vertical position by detecting the number of rotations of the elevation shafts 36 and 56. The first massage unit 8 detects the upper and lower positions of the first massage unit 8 by detecting how many rotations of the elevating shaft 36 have been performed from the upper limit position. The second massage unit 9 detects the upper and lower positions of the second massage unit 9 by detecting how many rotations of the elevating shaft 56 have been performed from the lower limit position.

[Operation control of collision avoidance]
When it is detected that both massage units 8 and 9 have reached a predetermined relative position (for example, a proximity state or a proximity state) while both massage units 8 and 9 move in the direction in which they approach each other, The control unit 25 controls to stop or reverse the driving of the lifting motor 35, and the sub control unit 26 controls to stop or reverse the driving of the lifting motor 55. The sub control units 25 and 26 also notify the main control unit 24 that the above control has been performed. In this way, a collision of both massage units 8, 9 is avoided.

  When raising and lowering of one massage unit (for example, the first massage unit 8) is stopped, the other massage unit (for example, the second massage unit 9) is moving in the direction approaching the one massage unit When it is detected that both massage units 8 and 9 have reached a predetermined relative position (for example, a proximity state or a proximity state), the sub control unit 26 controls to stop or reverse the driving of the lifting motor 55. Do. The sub control units 25 and 26 also notify the main control unit 24 that the above control has been performed. Note that, instead of or in addition to the above control, the sub control unit 25 may drive the elevating motor 35 to move the first massage unit 8 away from the second massage unit 9. In this way, a collision of both massage units 8, 9 is avoided.

  When both massage units 8 and 9 move up or down in the same direction, the massage unit on the front side in the traveling direction is controlled so that the lifting speed is faster than the massage unit on the rear side in the traveling direction Is controlled to start moving earlier than the massage unit on the rear side in the direction of travel. By doing this, the accuracy of the collision prevention further increases. In addition, if the raising and lowering speed of the massaging unit on the front side in the traveling direction is made relatively faster, or if the movement of the massaging unit on the front side in the traveling direction is started slightly earlier, It can be moved smoothly in the same direction in the state. That is, the sensor 70 frequently detects the proximity state, and it is possible to prevent the massage unit on the rear side in the traveling direction from being stopped or separated little by little.

[Massage operation]
Hereinafter, the massaging operation will be described in detail.
FIG. 16 is an explanatory view of the kneading operation. FIG. 17 is an explanatory view of the massaging operation, in which (a) is a massaging operation with the massaging unit 8 stopped moving up and down, (b) is a massaging operation with the massaging unit 8 lowered, and (c) is a massaging unit It shows a stagnation operation while raising 8. FIG. 18 is an explanatory view of the massaging operation, wherein (a) is a massaging operation with the massaging unit 8 stopped to move up and down, (b) is a massaging operation with the massaging unit 8 lifted, and (c) is a massaging unit It shows a stagnation operation while lowering 8. FIG. 19 is an explanatory view of the kneading operation. In addition, in FIG.16 and FIG.19, the state which arrange | positioned the 1st massaging unit 8 in the neck position and has arrange | positioned the 2nd massaging unit 9 in the shoulder position is shown.

  As shown in FIG. 16, when the massage motors 43 and 63 are driven to continuously rotate the kneading shafts 41 and 61 in one direction, the treatment elements 34 and 54 have horizontal and vertical components in a front view. It operates by drawing a loop-like locus. On the other hand, if the massaging shafts 41 and 61 are inverted before being rotated one turn, the treatment elements 34 and 54 draw an arc-like locus having components in the left and right and up and down directions in front view. In any of the above cases, the treatment elements 34 and 54 in the left and right pair move in the left and right direction to approach and separate. Thus, the massaging operation is performed.

  As shown in FIGS. 7 and 13, in the massage machine 1 according to this embodiment, the distance d1 between the massaging element 34 of the first massaging mechanism 31 and the massaging shaft 41 is the massaging element 54 of the second massaging mechanism 51 (upper massaging element It is set to be shorter than the distance d2 between the mass axis 61 and the mass axis 54a. Therefore, as shown in FIG. 16, the treatment element 34 of the first massaging mechanism 31 and the treatment element 54 of the second massaging mechanism 51 have different operation ranges in the lateral direction in the massaging operation. Specifically, treatment elements The operating range W1 of 34 is narrower than the operating range W2 of the massaging element 54. In addition, the treatment element 34 of the first massage mechanism 31 and the treatment element 54 of the second massage mechanism 51 have different upper and lower dimensions of the locus of the kneading operation, and specifically, the upper and lower dimensions of the locus of the treatment element 34 H1 is smaller than the upper and lower dimension H2 of the trajectory of the treatment element 54. The upper and lower dimensions of the movement range and the locus can also be made different by changing the inclination angles of the inclination axes 41a and 61a with respect to the axial centers 41b and 61b of the stagnation axes 41 and 61. Specifically, the upper and lower dimensions of the movement range and the locus can be increased as the inclination angle of the inclination axes 41a and 61a with respect to the axial centers 41b and 61b of the stagnation axes 41 and 61 is increased.

  With such a configuration, the first massaging mechanism 31 performs a relatively fine massaging operation on the narrow neck of the treatment range, and the second massaging mechanism 51 of the portion to be treated below the wide neck of the treatment range ( For example, dynamic itching can be performed on the shoulders, back, waist, etc.). That is, it is possible to perform an effective massaging operation according to the treatment site. Moreover, since both massage units 8 and 9 can move up and down, it is possible to switch between the first massage unit 8 and the second massage unit 9 to perform different massaging operations on the same treated part.

  Further, by moving the massaging units 8 and 9 up and down along the height direction in synchronization with the massaging operation, the upper and lower dimensions of the locus of the massaging operation can be changed. To illustrate the treatment element 34, as shown in FIG. 17B, if the first massage unit 8 is lowered in synchronization with the downward movement of the treatment element 34 due to the kneading operation, the upper and lower dimensions of the locus of the kneading operation H1 increases, and as shown in FIG. 17C, if the first massage unit 8 is raised in synchronization with the downward movement of the massaging device 34, the upper and lower dimension H1 of the massaging operation decreases. Alternatively, as shown in FIG. 18B, if the first massage unit 8 is lifted in synchronization with the upward movement of the massaging device 34 due to the massaging operation, the upper and lower dimension H1 of the locus of the massaging operation becomes larger. As shown in c), if the first massage unit 8 is lowered in synchronization with the upward movement of the massaging device 34 due to the massaging operation, the upper and lower dimension H1 of the massaging operation becomes smaller.

  By adopting such a configuration, it is possible to change the bodily sensation of the massaging operation in various ways. For example, the movement range in the left and right direction of the massaging operation is performed by switching the massage units 8 and 9 for massaging the treatment site, and the upper and lower dimensions of the locus of the massaging operation are It is good. In addition, although illustrated about the treatment element 34 of the 1st massage mechanism 31 in FIG.17 and FIG.18, the same massaging operation can be performed also about the treatment element 54 of the 2nd massage mechanism 51. FIG. In addition, in a configuration in which the massaging operation by the massage motor causes the treatment elements of the left and right pair to move close to each other with only the left and right direction components, the treatment elements have a vertical direction component by adding the elevation of the massage unit. It can be changed to an operation of drawing an arc or loop trajectory.

  As shown in FIG. 19 as another embodiment, in the first massaging mechanism 31 and the second massaging mechanism 51, the separation distance between the left and right pair of treatment elements 34 and 54 when closest to each other in the massaging operation is set to be different. It may be Specifically, it is preferable that the separation distance D1 of the first massaging mechanism 31 be set to be smaller than the separation distance D2 of the second massaging mechanism 51. The separation distance is caused by the distance between the attachment positions of the arms 40, 60 forming the pair to the stagnation shafts 41, 61, or the inclination angle of the tilt axes 41a, 61a with respect to the axis 41b, 61b of the stagnation shafts 41, 61. With such a configuration, the first massaging mechanism 31 performs a firm massaging operation on the neck, and the second massaging mechanism 51 provides a treatment site (for example, a shoulder, a back) below the wide neck of the treatment range. , The hips etc.) can be performed away from the central line (eg spine) of the body. That is, it is possible to perform an effective massaging operation according to the treatment site.

  Hereinafter, collaboration between the first massaging mechanism 31 and the second massaging mechanism 51 will be described.

[Operation 1]
FIG. 20 is a flowchart of the operation 1. FIG. 21 is an explanatory view of the operation 1; (a) is a state in which the first massaging mechanism 31 is advanced and the second massaging mechanism 51 is retracted; (b) is a state in which the first massaging mechanism 31 is retracted; Indicates that the company has made inroads.
The operation 1 is an operation for advancing and retracting the first massaging mechanism 31 and the second massaging mechanism 51 at different timings, and it is preferable to include the operation of the massaging elements 34 and 54 by driving the massaging motors 43 and 63. Hereinafter, as shown in FIG. 21, the case where the operation 1 is performed in a state where the first massage unit 8 is disposed at the neck position and the second massage unit 9 is disposed at the back position of the shoulder will be illustrated.

  As shown in FIG. 20, first, the first massaging mechanism 31 is advanced relative to the second massaging mechanism 51 (step S1). Subsequently, the second massaging mechanism 51 is advanced while maintaining the front and rear position of the first massaging mechanism 31 (step S2). Subsequently, with the front and back position of the second massaging mechanism 51 maintained, the first massaging mechanism 31 is retracted relative to the second massaging mechanism 51 (step S3). Subsequently, in a state in which the front and rear position of the first massaging mechanism 31 is maintained, the second massaging mechanism 51 is retracted (step S4). The cycle of steps S1 to S4 is repeated for a predetermined time. In the steps S1 to S4, the second massage mechanism 51 may be advanced first. Moreover, the position which arrange | positions each massage unit 8 and 9 is not specifically limited, For example, you may arrange | position the 1st massage unit 8 in a neck position, and may arrange | position the 2nd massage unit 9 in a waist position.

  In steps S1 to S4, it is preferable to drive the massage motors 43 and 63 to cause the treatment elements 34 and 54 to perform a massage including a massaging operation or a tapping operation, and the massage may be performed constantly. Alternatively, the massage may be performed intermittently. For example, the massage is performed when each of the massage mechanisms 31 and 51 is advanced, and the massage is performed when each of the massage mechanisms 31 and 51 is retracted. It may stop. In addition, the advancing or retreating of the massaging mechanism 31, 51 may be synchronized with the above-mentioned massage, in this case, to obtain a feeling as if the masseuse performs a massaging operation or a tapping operation while changing the degree of force. Can. Alternatively, the advancing or retreating of the massaging mechanism 31, 51 may be synchronized with the operation of bringing the left and right pair of treatment elements 34, 54 into proximity, in which case the masseuse pushes while grasping the treatment site. Or, it is possible to obtain a sensation as if pulling while holding the treatment site. Here, “synchronization” refers to the advancing and retracting drive units 15 and 16 for advancing or retracting the massaging mechanisms 31 and 51, and a massage motor 43 for performing a massaging operation, a tapping operation, or an operation for bringing a pair of treatment elements close to each other. , 63 may be performed in parallel regardless of whether the mass transfer mechanism is driven or not, and further includes the case of driving the massage motors 43, 63 after the advancing or retreating of the massaging mechanisms 31, 51 is completed.

  Alternatively, the massaging mechanisms 31 and 51 may be alternately advanced and retracted so that the other massaging mechanism is retracted in synchronism with the advancement of one massaging mechanism, in which case the masseur alternates with the left hand and the right hand. You can get a physical sensation as if you switched to the massage. Also, with one of the massaging mechanisms advanced, the other massaging mechanism may repeat advancing and retracting for a predetermined period of time, in which case as if a masseuse attached one hand to the treatment site, the other massage You can get a sensation that feels like repeating acupressure with your hand.

  Further, in steps S1 to S4, the raising and lowering motors 35 and 55 may be driven to raise and lower each massage unit 8, 9. For example, advancing of the massage mechanism 31, 51 and raising or lowering of the massage unit 8, 9 Can be synchronized, and in this case, it is possible to obtain a sensation as if the masseuse pushes up or down the treatment site. In this operation, it is preferable to synchronize the operation of bringing the left and right pairs of treatment elements close to each other.

  As described above, in the operation 1, since the massaging mechanisms 31 and 51 shift the timing to advance and retreat to perform the massage, it is possible to obtain a realistic sensation as if the masseur perform the massage using both hands. it can. In particular, when the massaging operation is performed as the massage, the massaging child's left and right massaging members simulate the massaging operation with the thumb and the other finger of the masseur's left hand, and the other massaging element's left and right pair The treatment child can simulate the massaging operation with the thumb and other fingers of the masseur's right hand. Moreover, since the sense of reality becomes remarkable by performing the operation 1 in a state in which both the massaging mechanisms 31 and 51 are brought close to each other in the vertical direction, it is preferable to perform in the above-described proximity state or proximity state based on the sensor 70 .

  In the embodiment described above, the massage mechanisms 31 and 51 are advanced or retracted at different timings to achieve a realistic sensation, but the speeds at which the massage mechanisms 31 and 51 are advanced or retracted Even if they are different, the same sensation can be obtained. For example, if the advancing speed of the first massaging mechanism 31 is made relatively faster than the advancing speed of the second massaging mechanism 51, even if the respective massaging mechanisms 31, 51 start advancing simultaneously, After pushing the treatment site by the treatment element 34, the treatment section 54 is pushed by the treatment element 54 of the second massage mechanism 51 a little later. Therefore, it is possible to obtain a sensation as if the masseur successively pushed the left and right hands into the treatment site.

[Operation 2]
FIG. 22 is a flowchart of the operations 2 and 3. FIG. 23 is an explanatory view of the operations 2 and 3. (a) shows a state in which the first and second massage mechanisms 31 and 51 are retracted, and (b) shows that the first and second massage mechanisms 31 and 51 are advanced State (c) shows a state in which the first massaging mechanism 31 has advanced and the second massaging mechanism 51 has been retracted. In FIG. 23, the shaded treatment elements 34, 54a, 54b indicate advanced states, and the non-shaded treatment elements 34, 54a, 54b indicate retracted states.

  Operation 2 is an operation for causing the treatment element 34 of the first massaging mechanism 31 and the treatment element 54 of the second massaging mechanism 51 to advance to the treatment site. Hereinafter, as shown in FIG. 23, the case where the operation 2 is performed in a state where the first massage unit 8 is disposed at the back position of the shoulder and the second massage unit 9 is disposed at the upper back will be illustrated.

  As shown in FIG. 22, first, the massaging units 8 and 9 are moved up and down to bring them close in the height direction (step S1). In this example, the first massage unit 8 is disposed at the back of the shoulder, and the second massage unit 9 is disposed at the upper back. Therefore, as shown in FIG. 23, the treatment element 34 and the upper treatment element 54a are in the state of being close in the height direction. Subsequently, the massage motors 43 and 63 are driven to make the positions of the treatment elements 34 of the first massaging mechanism 31 and the treatment elements 54 of the second massaging mechanism 51 different in the left-right direction as shown in FIG. S2). Subsequently, the advancing and retreating drive units 15 and 16 are driven to cause the first massage mechanism 31 and the second massage mechanism 51 to advance as shown in FIG. 23 (b) (step S3).

  In addition, what is necessary is just to determine the up-and-down space | interval of both massage units 8 and 9 in step S1 based on the sensor 70, for example, what is necessary is just to be in the proximity state mentioned above or the state before proximity. In step S2, the left and right positions of the treatment elements 34 and 54 may be determined based on the width sensors 46 and 66. Also, step S1 and step S2 may be performed in parallel. Moreover, in step S3, the first massaging mechanism 31 and the second massaging mechanism 51 may be advanced simultaneously, or may be advanced at different timings.

  In step S3, the massage motors 43 and 63 may be driven to perform a massaging operation or a tapping operation. For example, in the backrest portion 3, it is preferable to cause one of the massaging mechanisms to perform a massaging operation, and at the same time, to cause the other massaging mechanism to perform an operation including a tapping operation. By operating in this manner, it is possible to give a sensation as if two or more masseurs are performing different types of massage on the upper body. Although the masseur can perform the massaging operation with one hand, but can not perform the massaging operation with one hand, one masseur can not perform the massaging operation and the massaging operation in parallel.

  As described above, in operation 2, since the treatment elements 34 of the first massage mechanism 31 and the treatment elements 54 (upper treatment elements 54a) of the second massage mechanism 51 are aligned in the left-right direction, You can use it to get a realistic sensation, as if you were doing a massage (finger pressure) with your thumb and other fingers. That is, in the state shown in FIG. 23, the treatment elements 34 located on the left and right sides correspond to the thumb, and the upper treatment element 54a or the lower treatment element 54b located on the outer sides correspond to the other fingers. Moreover, although embodiment mentioned above demonstrated the case where the operation | movement 2 was performed in the state which the 1st massaging mechanism 31 and the 2nd massaging mechanism 51 approached, you may perform the operation | movement 2 in the separated state. In this case, for example, the treatment element 54 (upper treatment element 54a or lower treatment element 54b) located on the lower side corresponds to a thumb, and the treatment element 34 located on the upper side corresponds to the other finger.

[Operation 3]
Operation 3 is an operation of causing the treatment elements of one of the massage mechanisms to retract from a state in which positions of the treatment elements 34 of the first massage mechanism 31 and the treatment elements 54 of the second massage mechanism 51 are different in the left and right direction. It is. Hereinafter, as shown in FIG. 22, the case where the operation 3 is performed following the operation 2 will be illustrated.

  Subsequent to step S3 of the operation 2, the advancing and retracting drive unit is driven to retract any one of the massage mechanisms (step S4). In the example shown in FIG. 23, the advancing and retracting drive unit 16 is driven to retract the second massage mechanism 51. As a result, the treated portion strongly abuts on the treatment element 34 of the first massaging mechanism 31 that has advanced, and it is possible to obtain a physical sensation as if the treatment element 34 is finger-pressing. In addition, since the bodily sensation of a finger pressure becomes remarkable by performing in the state which both massaging mechanisms 31 and 51 approached, it is preferable to perform the operation | movement 3 in the proximity state mentioned above or the state before proximity based on the sensor 70. Further, in the operations 2 and 3, the positions at which the massage units 8 and 9 are disposed are not particularly limited. For example, the first massage unit 8 is disposed at the neck or back position, and the second massage unit 9 is at the waist position. It may be located at

[Operation 4]
FIG. 24 is an explanatory diagram of the operation 4. In FIG. 24, the lower massaging element 54b is omitted to facilitate understanding.
Operation 4 is an operation to perform the massaging operation at different speeds for the treatment element 34 of the first massaging mechanism 31 and the treatment element 54 of the second massaging mechanism 51, in which the massaging mechanisms 31 and 51 are close in the height direction. It is preferable to perform as.

  First, the massaging units 8 and 9 are moved up and down so that they approach each other in the height direction. Subsequently, the massaging motors 43 and 63 are continuously driven in one direction, and the massaging operation is performed by the massaging elements 34 of the first massaging mechanism 31 and the massaging elements 54 of the second massaging mechanism 51. This massaging operation is performed by rotating the massaging shafts 41 and 61 at different speeds by driving the massaging motors 43 and 63 at different speeds. In the example shown in FIG. 24, the rotation of the stagnation shaft 41 is made relatively fast. In addition, what is necessary is just to determine the up-and-down space of both the massage units 8 and 9 based on the sensor 70, for example, what is necessary is just to set it as the close state mentioned above or the state before proximity.

  As described above, in the operation 4, the massaging elements 34 and 54 of the massaging mechanisms 31 and 51 perform the kneading operation by repeating the cycle in which the locus in the loop shape is repeated one round. Then, in each cycle, the positional relationship between the other massage mechanism and the treatment element is different. For example, assuming that the treatment element 34 of the first massage mechanism 31 is a viewpoint, in the state where the treatment elements 34 of the first cycle are most apart, the treatment elements 54 of the second massage mechanism 51 are on the locus of the massaging action. When positioned at the upper end but the treatment elements 34 of the second cycle are most separated, the treatment elements 54 of the second massaging mechanism 51 are located at the lower end on the locus of the massaging operation. As described above, the operation 4 can change the massaging operation from the vertical direction by the treatment element 34 of the first massage mechanism 31 and the treatment element 54 of the second massage mechanism 51 with the passage of time, and the massage effect is enhanced. .

[Operation 5]
FIG. 25 is an explanatory view of the operation 5, in which (a) is a state in which the first and second massaging mechanisms 31, 51 are retracted, and (b) is a state in which the first massaging mechanism 31 is retracted and the second massaging mechanism 51 is advanced It shows the state.
As shown in FIG. 25, the operation 5 is an operation for advancing the second massaging mechanism 51 in a state where the first massaging unit 8 is disposed at the shoulder position and the second massaging unit 9 is disposed at the waist position. It is preferable to include the operation of the treatment element 34 by 43 driving. By advancing the second massaging mechanism 51 at the waist position, the waist is pushed forward and the upper body is turned upside down. Therefore, the shoulder strongly abuts on the treatment element 34 of the first massaging mechanism 31. At this time, if the massager 34 of the first massaging mechanism 31 performs a massaging operation or a tapping operation, the massage effect is enhanced.

[Operation 6]
FIG. 26 is an explanatory view of the operation 6, in which (a) shows the state where the first massage unit 8 is arranged at the shoulder position and the second massage unit 9 is arranged at the waist position, (b) shows the first massage unit 8 The second massage unit 9 is placed at the shoulder position, and shows a state in which the second massage unit 9 is raised to the back position.

At this time, if the massager 34 of the first massaging mechanism 31 performs a massaging operation or a tapping operation, the massage effect is enhanced.

[Operation 7]
FIG. 27 is an explanatory view of the operation 7, in which (a) is a state in which the first massaging mechanism 31 is advanced to clamp the neck and the second massaging mechanism 51 is disposed at the shoulder position, and (b) is the first massaging mechanism 31 shows the state where the second massage mechanism 51 has lowered to the waist position by advancing the neck 31 by gripping the neck.
An operation 7 is an operation for raising or lowering the other massage mechanism in the height direction in a state where the treatment object is held by the massaging members of one of the massage mechanisms. In the example shown in FIG. 27, the second massaging unit 9 is lowered with the first massaging mechanism 31 advanced and the pair of treatment elements 34 brought close to sandwich the neck. By lowering the second massage unit 9, the upper body is pulled downward. Therefore, since the neck is held by the massaging elements 34 of the first massaging mechanism 31, it is possible to obtain a stretching effect of stretching the neck. In addition, if the second massage unit 9 is repeatedly lifted and lowered while holding the neck by the first massaging mechanism, the masseuse applies one hand and fixes the neck with the other hand. It is possible to obtain a sensation as if you were touching or stretching the treatment site.

  In the operation | movement 7, the position in which each massage unit 8 and 9 is arrange | positioned is not specifically limited. Moreover, the massage mechanism which clamps a to-be-treated part, and the massage mechanism to raise or lower can be selected suitably. For example, the first massage unit 8 may be raised or lowered at the back position in a state where the second massage unit 9 is disposed at the waist position and the waist is held by the pair of treatment elements 54.

The operation is performed, and the second massaging mechanism 51 shows the state of the lowering process. An operation 8 is an operation of causing one massaging mechanism to perform a massaging operation or a tapping operation and raising or lowering the other massaging mechanism. Hereinafter, based on FIG. 28, the case where the massaging operation is performed as the first massaging mechanism 31 as the one massaging mechanism and the second massaging mechanism 51 is raised or lowered as the other massaging mechanism will be illustrated.

  As shown in FIG. 28 (a), by raising the second massaging mechanism 51 toward the first massaging mechanism 31 and bringing it close to the muscle, the muscle of the portion to be treated is brought closer to the first massaging mechanism 31 side. The adjacent muscles of the first massaging mechanism 31 can squeeze the gathered muscles. On the other hand, as shown in FIG. 28 (b), the muscle of the treatment site is pulled by lowering and separating the second massage mechanism 51 from the first massage mechanism 31 and this pulled muscle is The pair of treatment elements 34 of the first massaging mechanism 31 can suck. In addition, blood circulation can be promoted by moving the treatment site by raising or lowering the second massage mechanism 51, and the first massage mechanism 31 performs a massaging operation on the treatment site with enhanced blood circulation. Massage effect is further enhanced. In operation 8, the first massaging mechanism 31 may be raised or lowered to cause the second massaging mechanism 51 to perform a massaging operation or a tapping operation.

The operation of step S1 is continuously performed until the relative positions of the massage units 8 and 9 are in the proximity state or the proximity state. After completion of step S1, or in parallel with step S1, the treatment elements 34, 54 of the first and second massaging mechanisms 31, 51 are advanced (step S2). By operating in this manner, the spine can be stretched by the movement of the massaging mechanisms 31 and 51 along the height direction, and the upper body can be bent by the advancement of the treatment elements 34 and 54, thereby enhancing the massage effect. Then, after completion of step S2, the treatment elements 34, 54 of the first and second massaging mechanisms 31, 51 are retracted (step S3). In step S1, it is preferable to move the first and second massaging mechanisms 31 and 51 close to each other with the waist position as the target position. In this case, the effect of bending the upper body is enhanced.
