It is configured to have 33, 53 and.

Hereinafter, the configuration of the upper first massage unit 8 will be described in detail.
As shown in FIGS. 4 to 8, the main body frame 30 includes a rear wall 30a, a side wall 30b erected from both the left and right sides of the rear wall 30a, a bottom wall 30c erected from the lower part of the rear wall 30a, and a rear. It is configured in a box shape with the front open by the upper wall 30d erected from the upper part of the wall 30a. Further, above the inside of the main body frame 30, an elevating motor 35 for elevating and lowering the first massage unit 8, an elevating shaft 36 extending in the left-right direction, and a deceleration of the rotation of the elevating motor 35 are transmitted to the elevating shaft 36. An elevating mechanism composed of a speed reducer 37 is housed. The elevating shaft 36 is rotatably supported by both side walls 30b. The side wall 30b is provided with a guide roller 38 and a pinion 39 attached to the elevating shaft 36 at the upper portion, and a guide roller 38 and a pinion 39 are provided at the lower portion. The guide mechanism 3b is sandwiched between the pinion 39 and the guide roller 38, and when the elevating motor 35 is driven, the first massage unit 8 can be elevated and lowered along the height direction. Since the elevating mechanism is arranged on the upper part of the first massage unit 8, the treatment child 34 can be brought close to the treatment child 54 (upper treatment child 54a) of the second massage mechanism 51.

The first massage mechanism 31 has a pair of left and right arms 40 that support the treatment element 34 at the tip thereof, and a drive mechanism that drives the arms 40 to perform massage. This drive mechanism supports the arm 40 and causes the pair of treatment elements 34 to move apart from each other in the left-right direction to perform a kneading operation, and the pair of treatment elements 34 are alternately moved forward and backward to perform a tapping operation. A tapping shaft 42, a massage motor 43 as a massage drive unit for driving the kneading shaft 41 and the tapping shaft 42, and a speed reducer 44 for decelerating the rotation of the massage motor 43 and transmitting the massage to the kneading shaft 41 and the tapping shaft 42. Have. The drive mechanism is supported by a box-shaped frame 45. In this embodiment, the treatment element 34 of the first massage unit 8 is single in the vertical direction.

As shown in FIG. 9A, the kneading shaft 41 is extended in the left-right direction, and inclined shafts 41a inclined with respect to the axis 41b are provided on both the left and right sides. Then, the arm 40 is rotatably attached to the inclined shaft 41a via a bearing. The left and right inclined shafts 41a are not parallel to each other and are inclined so as to have a substantially C shape in front view. Further, the kneading 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 extends in the left-right direction, and eccentric shafts 42a eccentric with respect to the shaft center 42b are provided on both the left and right sides. Further, as shown in FIG. 5, a connecting member 47 connecting the tapping shaft 42 and the rear portion of the arm 40 is provided so as to be rotatable on the eccentric shaft 42a via a bearing. The left and right eccentric shafts 42a have different phases around the axis 42b of the tapping shaft 42.

When the kneading shaft 41 rotates, the arm 40 rotates three-dimensionally while the rotation around the kneading shaft 41 is restricted by the connecting member 47. That is, as shown in FIG. 16, when the kneading shaft 41 is continuously rotated in one direction, the treatment element 34 operates by drawing a loop-shaped locus having at least left-right and vertical components, and a pair of left-right treatment elements. As 34, it operates in the left-right direction and separates from each other. In this way, the kneading operation is performed. On the other hand, when the tapping shaft 42 rotates, the pair of arms 40 alternately advance and retreat with the kneading shaft 41 as a fulcrum due to the vertical movement of the connecting member 47. In this way, the tapping operation is performed. In the present embodiment, a clutch is provided on the tapping shaft 42 and a single massage motor 43 is inverted in the forward direction to switch between the kneading operation and the kneading tapping operation. However, the massage motor 43 is individually provided for kneading. The operation and the tapping operation may be performed independently.

The support frame 32 has a plate surface in the front-rear direction, and the frame 45 is fixed to the front side to support the first massage mechanism 31. Between the main body frame 30 and the support frame 32, there is an advancing / retreating air cell 15 as an advancing / retreating driving unit that expands / contracts due to air supply / exhaust from the air unit 20 to advance / retreat the first massage mechanism 31 with respect to the treated portion. It is provided. Further, on the side of the support frame 32, a link 33 that connects the main body frame 30 and the support frame 32 and swings in the front-rear direction is provided. The reason why the link 33 is arranged on the side of the support frame 32 is that the thickness of the massage unit 8 in the front-rear direction can be suppressed as compared with the case where the link 33 is arranged behind the support frame 32. The links 33 are arranged side by side in the front-rear direction and have a first link portion 33a relatively arranged on the rear side and a second link portion 33b relatively arranged on the front side. That is, the link 33 constitutes a four-node 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, and specifically, the length of the first link portion 33a is larger than the length of the second link portion 33b. Is also set to be short. The upper portion of the first link portion 33a is pivotally supported on the side wall 30b of the main body frame 30 via the swing shaft A1 in the vicinity of the elevating shaft 36, and the lower portion thereof is pivotally supported on the upper portion of the support frame 32 via the pivot shaft A2. Has been done. The upper portion of the second link portion 33b is pivotally supported on the side wall 30b of the main body frame 30 via the swing shaft A3 in the vicinity of the elevating shaft 36, and the lower portion thereof is pivotally supported on the lower portion of the support frame 32 via the pivot shaft A4. Has been done. The swing shaft A1 of the first link portion 33a is located slightly behind the swing shaft A3 of the second link portion 33b. Then, the first link portion 33a and the second link portion 33b are formed by fitting the pivot axes A2 and A4 to the downwardly convex arcuate guide portions 30e and 30f (see FIG. 4) provided on the side wall 30b, respectively. , Its operation is guided. Further, as shown in FIGS. 7 and 8, a reinforcing portion 48 is provided to connect and reinforce the first link portion 33a and the second link portion 33b at the connecting portion with the main body frame 30. In this way, the vicinity of the swing shafts A1 and A3 of the link 33 to which the load is applied can be reinforced by the elevating shaft 36 and the reinforcing portion 48.

The link 33 has a connecting portion with the main body frame 30 located in front of the connecting portion with the support frame 32 in a state where the first massage mechanism 31 is most retracted. That is, in the first link portion 33a, the swing axis A1 is located in front of the pivot axis A2, and in the second link portion 33b, the swing axis A3 is located in front of the pivot axis A4. Therefore, when the advancing / retreating air cell 15 expands, the link 33 swings in a downwardly convex arcuate locus, so that the first massage mechanism 31 is advanced / retracted in a locus close to parallel to the direction facing the treated portion. Can be done. Further, since the four-node link mechanism is adopted, when the advancing / retreating air cell 15 expands from the state where the first massage mechanism 31 is most retracted, the first link portion 33a swings forward about the swing shaft A1. However, since the support frame 32 is pivotally supported by the second link portion 33b, which is longer than the first link portion 33a, in front of and below the pivot axis A2 of the first link portion 33a, the first massage mechanism 31 swings. It is possible to advance and retreat in a trajectory that is closer to parallel to the direction facing the treated area.

Further, since the lengths of the first link portion 33a and the second link portion 33b are different, 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 first massage mechanism 31 is sufficient. A large amount of advancement can be secured, and the thickness of the first massage unit 8 in the front-rear direction can be suppressed. Further, since the length of the first link 33a arranged on the rear side is relatively short, a sufficient amount of movement of the front-back component is obtained immediately after the start of advancement, starting from the state where the first massage mechanism 31 is most retracted. be able to. Further, in the process of advancing the first massage mechanism 31, the first link portion 33a abuts on the second link portion 33b from the rear, so that the advance of the first massage mechanism 31 is restricted at a predetermined front-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 main body frame 50 includes a rear wall 50a, a side wall 50b erected from both the left and right sides of the rear wall 50a, a bottom wall 50c erected from the lower part of the rear wall 50a, and a rear wall. It is configured in a box shape with the front open by the upper wall 50d erected from the upper part of the wall 50a. Further, below the inside of the main body frame 50, an elevating motor 55 for elevating and lowering the second massage unit 9, an elevating shaft 56 extending in the left-right direction, and a deceleration of the rotation of the elevating motor 55 are transmitted to the elevating shaft 56. An elevating mechanism composed of a speed reducer 57 is housed. The elevating shaft 56 is rotatably supported by both side walls 50b. The side wall 50b is provided with a guide roller 58 and a pinion 59 attached to the elevating shaft 56 at the lower portion, and a guide roller 58 and a pinion 59 are provided at the upper portion. The guide mechanism 3b is sandwiched between the pinion 59 and the guide roller 58, and when the elevating motor 55 is driven, the second massage unit 9 can be elevated and lowered along the height direction. Since the elevating mechanism is arranged at the lower part of the second massage unit 9, the treatment child 54 (upper treatment child 54a) can be brought close to the treatment child 34 of the first massage mechanism 31.

The second massage mechanism 51 has a pair of left and right arms 60 that support the treatment element 54 at the tip thereof, and a drive mechanism that drives the arms 60 to perform massage. This drive mechanism includes a kneading shaft 61 that supports the arm 60 and causes a pair of treatment elements 54 to move apart from each other in the left-right direction to perform a kneading operation, and a massage motor 63 as a massage driving unit that drives the kneading shaft 61. It has a speed reducer 64 that slows down the rotation of the massage motor 63 and transmits it to the kneading shaft 61. The drive mechanism is supported by a box-shaped frame 65. The arm 60 is formed in a dogleg shape in a side view, and a relatively large-diameter upper treatment child 54a is provided at the upper end thereof, and a relatively small-diameter lower treatment child 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 kneading shaft 61 has the same configuration as the kneading shaft 41 of the first massage 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. Then, the arm 60 is rotatably attached to the inclined shaft 61a via the bearing. The left and right inclined shafts 61a are not parallel to each other and are inclined so as to have a substantially C shape when viewed from the front. As shown in FIG. 15, behind 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 along the left-right direction is provided on the front surface side of the support frame 52, and the ball joint of the connecting member 67 is fitted in the groove 69. Further, the kneading shaft 61 is provided with a width sensor 66 that detects the distance between the pair of treatment elements 54.

When the kneading shaft 61 rotates, the arm 60 rotates three-dimensionally while the rotation around the kneading shaft 61 is restricted by the connecting member 67. That is, as shown in FIG. 16, when the kneading shaft 61 is continuously rotated in one direction, the treatment element 54 operates by drawing a loop-shaped locus having at least left-right and vertical components. Further, the left and right pair of treatment elements 54 operate in the left-right direction, and when the upper treatment child 54a is close to each other, the lower treatment child 54b is separated, and when the upper treatment child 54a is separated, the lower treatment child 54b is close to each other. In this way, the kneading operation is performed. In the present embodiment, the second massage mechanism 51 is configured to perform only the kneading operation, but it may be configured to be able to perform the tapping operation as well as the first massage mechanism 31.

The support frame 52 has a plate surface in the front-rear direction, and the frame 65 is fixed to the front surface side to support the second massage mechanism 51. Between the main body frame 50 and the support frame 52, there is an advancing / retreating air cell 16 as an advancing / retreating drive unit that expands / contracts due to air supply / exhaust from the air unit 20 to advance / retreat the second massage mechanism 51 with respect to the treated portion. It is provided. Further, on the side of the support frame 52, a link 53 that connects the main body frame 50 and the support frame 52 and swings in the front-rear direction is provided. The link 53 is arranged side by side in the front-rear direction and has a first link portion 53a arranged relatively rearward and a second link portion 53b relatively arranged on the front side. That is, the link constitutes a four-section link mechanism.

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 portion of the first link portion 53a is pivotally supported on the side wall 60b of the main body frame 60 via the swing shaft A5 in the vicinity of the elevating shaft 56, and the upper portion thereof is pivotally supported on the lower portion of the support frame 52 via the pivot shaft A6. Has been done. The lower portion of the second link portion 53b is pivotally supported on the side wall 60b of the main body frame 60 via the swing shaft A7 in the vicinity of the elevating shaft 56, and the upper portion thereof is pivotally supported on the upper portion of the support frame 52 via the pivot shaft A8. Has been done. The swing shaft A5 of the first link portion 53a is located slightly behind the swing shaft A7 of the second link portion 53b. The first link portion 53a and the second link portion 53b are provided with the side wall 50b, and the pivot axes A6 and A8 are fitted to the convex arcuate guide portions 50e and 50f (see FIG. 10), respectively. , Its operation is guided. Further, as shown in FIGS. 13 and 14, a reinforcing portion 68 is provided to connect and reinforce the first link portion 53a and the second link portion 53b at the connecting portion with the main body frame 60. In this way, the vicinity of the swing shafts A5 and A7 of the link 53 to which the load is applied can be reinforced by the elevating shaft 56 and the reinforcing portion 68.

In the link 53, the connecting portion with the main body frame 60 is located in front of the connecting portion with the support frame 62 in a state where the second massage mechanism 51 is most retracted. That is, in the first link portion 53a, the swing axis A5 is located in front of the pivot axis A6, and in the second link portion 53b, the swing axis A7 is located in front of the pivot axis A8. Therefore, when the advancing / retreating air cell 16 expands, the link 53 swings in an upwardly convex arcuate locus, so that the second massage mechanism 51 is advanced / retracted in a locus close to parallel to the direction facing the treated portion. Can be done. Further, since the four-node link mechanism is adopted, when the advancing / retreating air cell 16 expands from the state where the second massage mechanism 51 is most retracted, the first link portion 53a swings forward about the swing shaft A5. However, since the support frame 52 is pivotally supported by the second link portion 53b, which is longer than the first link portion 53a, in front of and above the pivot axis A6 of the first link portion 53a, the second massage mechanism 51 swings. It is possible to advance and retreat in a trajectory that is closer to parallel to the direction facing the treated area.

Further, since the lengths of the first link portion 53a and the second link portion 53b are different, even if the first link portion 53a and the second link portion 53b are provided close to each other in the front-rear direction, the second massage mechanism 51 is sufficient. A large amount of advancement can be secured, and the thickness of the second massage unit 9 in the front-rear direction can be suppressed. Further, since the length of the first link 53a arranged on the rear side is relatively short, a sufficient amount of movement of the anteroposterior component is obtained immediately after the start of advancement, starting from the state where the second massage mechanism 51 is most retracted. 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 the rear, so that the advance of the second massage mechanism 51 is restricted at a predetermined front-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 positions of the first massage unit 8 and the second massage unit 9. Hereinafter, the sensor 70 will be described in detail.

As shown in FIG. 4, the bottom wall 30c, which is the lower part of the first massage unit 8, is provided with a magnet holder 73 having a magnet attached to one side in the left-right direction, and the first is to detect the proximity of the magnet to 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. A sub-control unit 26 (see FIG. 2) is provided, and a magnet holder 74 to which a magnet is attached is provided on the other side in the left-right direction. The sub control units 25 and 26 are electrically connected to the elevating motors 35 and 55, respectively, and can control the elevating and lowering of the massage units 8 and 9, respectively. It is also electrically connected to the main control unit 24.

The first sensor unit 71 substantially coincides with the magnet holder 74 provided in the second massage unit 9 at positions orthogonal to the vertical direction, and detects the proximity of the second massage unit 9 to the first massage unit 8. Can be done. On the other hand, the second sensor unit 72 substantially coincides with the magnet holder 73 provided in the first massage unit 8 at positions orthogonal to 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, the respective massage units 8 and 9 detect the proximity of the massage units 9 and 8 on the other side, and the respective sub control units 25 and 26 control the elevating motors 33 and 55 to prevent collision. Increased accuracy.

It is preferable that the sensor 70 can detect the distance between the massage units 8 and 9 in a plurality of stages as the relative positions of the first massage unit 8 and the second massage unit 9. For example, it suffices to be able to detect a two-stage state in which the distance between the massage units 8 and 9 is close to a predetermined distance, and the state is slightly separated from the close state. Therefore, the detection range of the relative positions of the first massage unit 8 and the second massage unit 9 is widened. Further, both massage units 8 and 9 can be moved up and down integrally with a predetermined relative position (for example, a proximity state or a pre-proximity state) while maintaining this relative position.

As shown in FIG. 2, the backrest portion 3 includes an upper limit sensor 75 for detecting the upper limit position of the elevating range of the first massage unit 8 and a lower limit sensor 76 for detecting the lower limit position of the elevating range of the second massage unit 9. , Are provided so that the first and second massage units 8 and 9 do not separate from the backrest portion 3. Further, the first and second massage units 8 and 9, respectively, have elevating sensors 77 and 78 that detect the vertical position by detecting the rotation speeds of the elevating shafts 36 and 56, respectively. The up-down position of the first massage unit 8 is detected by the elevating sensor 77 detecting how many rotations of the elevating shaft 36 are from the upper limit position. The up-down position of the second massage unit 9 is detected by the elevating sensor 78 detecting how many rotations of the elevating shaft 56 are from the lower limit position.

[Collision avoidance operation control]
If it is detected that both massage units 8 and 9 are in a predetermined relative position (for example, a proximity state or a pre-proximity state) while both massage units 8 and 9 are moving in a direction approaching each other, a sub The control unit 25 controls to stop or reverse the drive of the elevating motor 35, and the sub control unit 26 controls to stop or reverse the drive of the elevating motor 55. Further, each of the sub control units 25 and 26 informs the main control unit 24 that the above control has been performed. In this way, the collision of both massage units 8 and 9 is avoided.

When one massage unit (for example, the first massage unit 8) is stopped to move up and down, and the other massage unit (for example, the second massage unit 9) is moving in a direction approaching one massage unit. When it is detected that both massage units 8 and 9 are in a predetermined relative position (for example, a proximity state or a proximity state), the sub control unit 26 controls to stop or reverse the drive of the elevating motor 55. do. Further, each of the sub control units 25 and 26 informs the main control unit 24 that the above control has been performed. In addition to or in addition to the above control, the sub control unit 25 may drive the elevating motor 35 to control the first massage unit 8 to move away from the second massage unit 9. In this way, the collision of both massage units 8 and 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 ascending / descending speed is faster than the massage unit on the rear side in the traveling direction, or the massage unit on the front side in the traveling direction. Controls to start moving before the massage unit on the rear side in the direction of travel. By doing so, the accuracy of collision prevention is further improved. Further, if the ascending / descending speed of the massage unit on the front side in the traveling direction is relatively slightly increased, or if the movement of the massage unit on the front side in the traveling direction is started relatively slightly earlier, both massage units 8 and 9 are brought closer to each other. It can be smoothly moved in the same direction in the state. That is, it is possible to prevent the sensor 70 from frequently detecting the proximity state and causing the massage unit on the rear side in the traveling direction to stop or separate in small steps.

[Massage operation]
Hereinafter, the kneading operation will be described in detail.
FIG. 16 is an explanatory diagram of the kneading operation. 17A and 17B are explanatory views of a kneading operation, in which (a) is a kneading operation in a state where the ascending / descending of the massage unit 8 is stopped, (b) is a kneading operation while lowering the massage unit 8, and (c) is a massage unit. It shows a kneading operation while raising 8. FIG. 18 is an explanatory diagram of a kneading operation, in which (a) is a kneading operation in a state where the ascending / descending of the massage unit 8 is stopped, (b) is a kneading operation while raising the massage unit 8, and (c) is a massage unit. It shows a kneading operation while lowering 8. FIG. 19 is an explanatory diagram of the kneading operation. 16 and 19 show a state in which the first massage unit 8 is arranged at the neck position and the second massage unit 9 is arranged at the shoulder position.

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 left and right and vertical components are viewed from the front as the treatment elements 34 and 54. It operates by drawing a loop-shaped locus. On the other hand, when the kneading shafts 41 and 61 are inverted before being rotated once, the treatment elements 34 and 54 operate by drawing an arc-shaped locus having left-right and vertical components in the front view. In any of the above cases, the left and right pairs of treatment elements 34 and 54 operate in the left-right direction and separate from each other. In this way, the kneading operation is performed.

As shown in FIGS. 7 and 13, in the massage machine 1 according to the present embodiment, the distance d1 between the treatment child 34 of the first massage mechanism 31 and the kneading shaft 41 is the treatment child 54 (upper treatment child) of the second massage mechanism 51. It is set to be shorter than the distance d2 between 54a) and the kneading shaft 61. Therefore, as shown in FIG. 16, the treatment child 34 of the first massage mechanism 31 and the treatment child 54 of the second massage mechanism 51 have different operating ranges in the left-right direction in the kneading operation. The operating range W1 of the 34 is narrower than the operating range W2 of the treatment element 54. Further, the treatment child 34 of the first massage mechanism 31 and the treatment child 54 of the second massage mechanism 51 are different in the vertical dimension of the locus of the kneading operation. Specifically, the vertical dimension of the locus of the treatment child 34 is different. H1 is smaller than the vertical dimension H2 of the locus of the treatment element 54. It should be noted that the vertical dimension of the locus can also be made different from the operating range by making the inclination angles of the inclined shafts 41a and 61a different from the axial centers 41b and 61b of the kneading shafts 41 and 61. Specifically, the larger the inclination angle of the inclined shafts 41a and 61a with respect to the axial centers 41b and 61b of the kneading shafts 41 and 61, the larger the vertical dimension of the operating range and the locus can be increased.

With such a configuration, the first massage mechanism 31 performs a relatively fine kneading operation on the neck having a narrow treatment range, and the second massage mechanism 51 performs a relatively fine kneading operation, and the second massage mechanism 51 performs a treatment portion below the neck having a wide treatment range ( For example, a dynamic massage motion can be performed on the shoulder, back, waist, etc.). That is, an effective kneading operation can be performed according to the treatment site. Further, since both massage units 8 and 9 can be raised and lowered, the first massage unit 8 and the second massage unit 9 can be switched to perform different kneading operations on the same treated portion.

Further, by raising and lowering each of the massage units 8 and 9 along the height direction in synchronization with the kneading operation, the vertical dimension of the locus of the kneading operation can be changed. Explaining the treatment element 34 as an example, as shown in FIG. 17B, if the first massage unit 8 is lowered in synchronization with the downward operation due to the kneading operation of the treatment element 34, the vertical dimension of the locus of the kneading operation. H1 becomes large, and as shown in FIG. 17C, if the first massage unit 8 is raised in synchronization with the downward movement due to the kneading operation of the treatment element 34, the vertical dimension H1 of the kneading operation becomes small. Alternatively, as shown in FIG. 18B, if the first massage unit 8 is raised in synchronization with the upward movement due to the kneading movement of the treatment element 34, the vertical dimension H1 of the locus of the kneading movement becomes large, and FIG. As shown in c), if the first massage unit 8 is lowered in synchronization with the upward movement of the massager 34 due to the kneading operation, the vertical dimension H1 of the kneading operation becomes smaller.

With such a configuration, the feeling of the kneading operation can be changed in various ways. For example, the horizontal movement range of the kneading operation is performed by switching the massage units 8 and 9 that massage the treated area, and the vertical dimension of the kneading operation trajectory is performed by adding the raising and lowering of the massage units 8 and 9. Just do it. Although the treatment element 34 of the first massage mechanism 31 is illustrated in FIGS. 17 and 18, the same kneading operation can be performed on the treatment element 54 of the second massage mechanism 51. Further, in the case where the kneading operation by the massage motor is such that the left and right pairs of the treatment elements have only the left and right direction components and are separated from each other, the massage unit is moved up and down to make the treatment child a circle having the vertical direction components. It can be changed to an operation of drawing an arc-shaped or loop-shaped locus.

As another embodiment, as shown in FIG. 19, the first massage mechanism 31 and the second massage mechanism 51 are set so that the separation distances of the left and right pairs of treatment elements 34 and 54 when they are closest to each other in the kneading operation are different. May be. Specifically, it is preferable that the separation distance D1 of the first massage mechanism 31 is set to be narrower than the separation distance D2 of the second massage mechanism 51. The separation distance is caused by the distance between the attachment positions of the paired arms 40 and 60 to the kneading shafts 41 and 61, or the inclination angle of the tilting shafts 41a and 61a with respect to the axis 41b and 61b of the kneading shafts 41 and 61. With such a configuration, the first massage mechanism 31 performs a firm kneading operation on the neck, and the second massage mechanism 51 performs a treatment portion below the neck having a wide treatment range (for example, shoulders and back). , The waist, etc.) can be massaged while avoiding the vicinity of the center line of the body (for example, the spine). That is, an effective kneading operation can be performed according to the treatment site.

Hereinafter, the cooperation between the first massage mechanism 31 and the second massage mechanism 51 will be described.

[Operation 1]
FIG. 20 is a flow chart of operation 1. 21 is an explanatory diagram of operation 1, in which (a) is a state in which the first massage mechanism 31 is advanced and the second massage mechanism 51 is retracted, and (b) is a state in which the first massage mechanism 31 is retracted and the second massage mechanism 51 is retracted. Shows the state of advancement.
The operation 1 is an operation of advancing and retreating the first massage mechanism 31 and the second massage mechanism 51 at different timings, and preferably includes the operations of the treatment elements 34 and 54 driven by the massage motors 43 and 63. Hereinafter, as shown in FIG. 21, a case where the operation 1 is performed with the first massage unit 8 arranged at the neck position and the second massage unit 9 arranged at the back position of the shoulder will be illustrated.

As shown in FIG. 20, first, the first massage mechanism 31 is relatively advanced with respect to the second massage mechanism 51 (step S1). Subsequently, the second massage mechanism 51 is advanced while maintaining the front-back position of the first massage mechanism 31 (step S2). Subsequently, the first massage mechanism 31 is retracted relative to the second massage mechanism 51 while maintaining the front-back position of the second massage mechanism 51 (step S3). Subsequently, the second massage mechanism 51 is retracted while maintaining the front-back position of the first massage mechanism 31 (step S4). The cycle of steps S1 to S4 is repeated for a predetermined time. In steps S1 to S4, the second massage mechanism 51 may be advanced first. Further, the position where the massage units 8 and 9 are arranged is not particularly limited, and for example, the first massage unit 8 may be arranged at the neck position and the second massage unit 9 may be arranged at the 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 kneading operation or a tapping operation, and the massage may be performed at all times. Alternatively, the massage may be performed intermittently, for example, the massage is performed when the massage mechanisms 31 and 51 are advanced, and the massage is performed when the massage mechanisms 31 and 51 are retracted. You may stop. Further, the advancement or retreat of the massage mechanisms 31 and 51 may be synchronized with the massage. In this case, it is possible to obtain a feeling as if the masseuse performs a kneading operation or a tapping operation while changing the force. Can be done. Alternatively, the advance or retreat of the massage mechanisms 31 and 51 may be synchronized with the operation of bringing the left and right pairs of the treatment elements 34 and 54 close to each other. Alternatively, it is possible to obtain a feeling as if pulling while grasping the treated portion. The term "synchronization" as used herein means a massage motor 43 that performs a kneading operation, a tapping operation, or an operation of bringing a pair of treatment elements into close proximity to the advancing / retreating drive units 15 and 16 that advance or retreat the massage mechanisms 31 and 51. , 63 may be driven in parallel regardless of the rear end, and further includes the case where the massage motors 43 and 63 are driven after the advancement or retreat of the massage mechanisms 31 and 51 is completed.

Further, the massage mechanisms 31 and 51 may be alternately advanced and retreated so as to retract the other massage mechanism in synchronization with the advancement of one massage mechanism. In this case, the masseuse alternates between the left hand and the right hand. You can get the feeling as if you are doing a massage by switching to. Further, with one massage mechanism advanced, the other massage mechanism may repeat advancement and retreat for a predetermined time. In this case, the masseuse attaches one hand to the treated area and the other. You can get the feeling of repeating acupressure with your hands.

Further, in steps S1 to S4, the elevating motors 35 and 55 may be driven to move the massage units 8 and 9 up and down. For example, the advancement of the massage mechanisms 31 and 51 and the ascent or descent of the massage units 8 and 9 may occur. In this case, it is possible to obtain a feeling as if the masseuse pushes up or pushes down the treated portion. In addition, it is preferable that this operation also synchronizes the operation of bringing the left and right pairs of treatments close to each other.

In this way, in the operation 1, since the massage mechanisms 31 and 51 move forward and backward at different timings to perform the massage, it is possible to obtain a realistic sensation as if the masseuse massages with both hands. can. In particular, when performing a kneading motion as the massage, the left and right pair of massagers of one massage mechanism simulates the kneading motion of the thumb and the other finger of the massager's left hand, and the left and right pair of the other massage mechanism. The treatment child can simulate the massage movement with the thumb and other fingers of the massager's right hand. Further, since the realistic feeling becomes remarkable by performing the operation 1 in a state where both massage mechanisms 31 and 51 are brought close to each other in the vertical direction, it is preferable to perform the operation 1 in the above-mentioned close state or the pre-close state based on the sensor 70. ..

Further, in the above-described embodiment, the massage mechanisms 31 and 51 are advanced or retracted at different timings to realize a realistic sensation, but the speeds at which the massage mechanisms 31 and 51 are advanced or retracted are set to each other. You can get the same experience even if you make them different. For example, when the advance speed of the first massage mechanism 31 is made relatively faster than the advance speed of the second massage mechanism 51, even if the advancement of the massage mechanisms 31 and 51 starts at the same time, the advance speed of the first massage mechanism 31 After pushing the treated portion with the treatment child 34, the treated portion is pushed with the treatment child 54 of the second massage mechanism 51 with a slight delay. Therefore, it is possible to obtain a feeling as if the masseuse pushes the left hand and the right hand into the treated portion in sequence.

[Operation 2]
FIG. 22 is a flow chart of operation 2 and operation 3. 23 is an explanatory diagram of operation 2 and operation 3, in which (a) is a state in which the first and second massage mechanisms 31 and 51 are retracted, and (b) is a state in which the first and second massage mechanisms 31 and 51 are advanced. The state, (c), shows a state in which the first massage mechanism 31 has advanced and the second massage mechanism 51 has retracted. In FIG. 23, the shaded treatment elements 34, 54a, 54b indicate the advanced state, and the shaded treatment elements 34, 54a, 54b indicate the retracted state.

The operation 2 is an operation in which the treatment child 34 of the first massage mechanism 31 and the treatment child 54 of the second massage mechanism 51 advance to the treated portion. Hereinafter, as shown in FIG. 23, a case where the operation 2 is performed with the 1 massage unit 8 arranged at the back position of the shoulder and the 2nd massage unit 9 arranged at the upper part of the back will be illustrated.

As shown in FIG. 22, first, the massage units 8 and 9 are moved up and down so that they are close to each other in the height direction (step S1). In this example, the first massage unit 8 is arranged at the back position of the shoulder, and the second massage unit 9 is arranged at the upper back. Therefore, as shown in FIG. 23, the treatment child 34 and the upper treatment child 54a are in a state of being close to each other in the height direction. Subsequently, the massage motors 43 and 63 are driven so that the positions of the treatment child 34 of the first massage mechanism 31 and the treatment child 54 of the second massage mechanism 51 in the left-right direction are different as shown in FIG. 23 (a) (step). S2). Subsequently, the advance / retreat drive units 15 and 16 are driven to advance the first massage mechanism 31 and the second massage mechanism 51 as shown in FIG. 23 (b) (step S3).

In step S1, the vertical distance between the massage units 8 and 9 may be determined based on the sensor 70, and may be, for example, the above-mentioned proximity state or pre-proximity state. Further, in step S2, the left-right positions of the treatment elements 34 and 54 may be determined based on the width sensors 46 and 66. Further, step S1 and step S2 may be performed in parallel. Further, in step S3, the first massage mechanism 31 and the second massage mechanism 51 may be advanced at the same time, or may be advanced at different timings.

In step S3, the massage motors 43 and 63 may be driven to perform a kneading operation or a tapping operation. For example, in the backrest portion 3, it is preferable to have one massage mechanism perform a kneading operation and, in parallel with it, cause the other massage mechanism to perform an operation including a tapping operation. By operating in this way, it is possible to give the feeling as if two or more masseurs are performing different types of massage on the upper body. Although the masseuse can perform the kneading motion with one hand, the masseuse cannot perform the tapping motion with one hand, so that one masseuse cannot perform the kneading motion and the tapping motion in parallel.

In this way, in the operation 2, the masseuse 34 of the first massage mechanism 31 and the massager 54 (upper massager 54a) of the second massage mechanism 51 are arranged side by side in the left-right direction, so that the masseuse has both hands. You can use it to get a realistic feeling as if you were doing a massage (acupressure) with your thumb and other fingers. That is, in the state shown in FIG. 23, the treatment child 34 located on the left and right inside corresponds to the thumb, and the upper treatment child 54a or the lower treatment child 54b located on the left and right outside corresponds to the other fingers. Further, in the above-described embodiment, the case where the operation 2 is performed in a state where the first massage mechanism 31 and the second massage mechanism 51 are close to each other has been described, but the operation 2 may be performed in a state where the first massage mechanism 31 and the second massage mechanism 51 are separated from each other. In this case, for example, the lower treatment child 54 (upper treatment child 54a or lower treatment child 54b) corresponds to the thumb, and the upper treatment child 34 corresponds to the other finger.

[Operation 3]
The operation 3 is an operation in which the treatment child 34 of the first massage mechanism 31 and the treatment child 54 of the second massage mechanism 51 are positioned differently in the left-right direction, and the treatment child of one of the massage mechanisms is retracted from the advanced state. Is. Hereinafter, as shown in FIG. 22, a case where the operation 3 is performed following the operation 2 will be illustrated.

Following step S3 of operation 2, the advance / retreat drive unit is driven to retract one of the massage mechanisms (step S4). In the example shown in FIG. 23, the advancing / retreating driving unit 16 is driven to retract the second massage mechanism 51. Then, the treated portion strongly abuts on the treated child 34 of the first massage mechanism 31 that has advanced, and it is possible to obtain a feeling as if the acupressure is being pressed by the treated child 34. It should be noted that the operation 3 is preferably performed in the above-mentioned close state or pre-close state based on the sensor 70, because the acupressure is noticeably felt when both massage mechanisms 31 and 51 are close to each other. Further, in the movements 2 and 3, the positions where the massage units 8 and 9 are arranged are not particularly limited. For example, the first massage unit 8 is arranged at the neck or back position and the second massage unit 9 is placed at the waist position. May be placed in.

[Operation 4]
FIG. 24 is an explanatory diagram of operation 4. In addition, in FIG. 24, the illustration of the lower treatment child 54b is omitted for ease of understanding.

It is preferable to carry out as.

First, the massage units 8 and 9 are moved up and down so that they are close to each other in the height direction. Subsequently, the massage motors 43 and 63 are continuously driven in one direction, and the massager 34 of the first massage mechanism 31 and the treatment child 54 of the second massage mechanism 51 perform a kneading operation. This kneading operation is performed by driving the respective massage motors 43 and 63 at different speeds to rotate the respective kneading shafts 41 and 61 at different speeds. In the example shown in FIG. 24, the rotation of the kneading shaft 41 is relatively fast. The vertical distance between the massage units 8 and 9 may be determined based on the sensor 70, and may be, for example, the above-mentioned proximity state or pre-proximity state.

In this way, the operation 4 repeats the cycle in which the treatment elements 34 and 54 of the massage mechanisms 31 and 51 make one round of the loop-shaped locus to perform the kneading operation. Then, the positional relationship with the treatment child of the other massage mechanism is different in each cycle. For example, when the treatment child 34 of the first massage mechanism 31 is viewed, the pair of treatment children 54 of the second massage mechanism 51 are on the trajectory of the kneading motion in the state where the pair of treatment children 34 in the first cycle are most separated. Although it is located at the upper end, in the state where the pair of treatment elements 34 in the second cycle are most separated from each other, the pair of treatment elements 54 of the second massage mechanism 51 are located at the lower end on the trajectory of the kneading operation. In this way, the operation 4 can change the kneading operation from the vertical direction by the treatment child 34 of the first massage mechanism 31 and the treatment child 54 of the second massage mechanism 51 with the passage of time, and the massage effect is enhanced. ..

[Operation 5]
25 is an explanatory diagram of operation 5, in which (a) is a state in which the first and second massage mechanisms 31 and 51 are retracted, and (b) is a state in which the first massage mechanism 31 is retracted and the second massage mechanism 51 is advanced. It shows the state.

It is preferable to include the operation of the treatment element 34 driven by the 43. By advancing the second massage mechanism 51 at the waist position, the waist is pushed forward and the upper body is in a posture of leaning back. Therefore, the shoulder strongly abuts on the treatment element 34 of the first massage mechanism 31. At this time, if the treatment child 34 of the first massage mechanism 31 is subjected to a kneading operation or a tapping operation, the massage effect is enhanced.

[Operation 6]
26 is an explanatory diagram of operation 6, in which the first massage unit 8 is arranged at the shoulder position and the second massage unit 9 is arranged at the waist position, and FIG. 26B shows the first massage unit 8 at the waist position. It shows a state in which the second massage unit 9 is arranged at the shoulder position and is raised to the back position.

In the example shown in FIG. 27, the second massage unit 9 is lowered while the first massage mechanism 31 is advanced and the pair of treatment elements 34 are brought close to each other and the neck is sandwiched. By lowering the second massage unit 9, the upper body is pulled downward. Therefore, since the neck is sandwiched by the treatment child 34 of the first massage mechanism 31, a stretching effect of stretching the neck can be obtained. Further, if the second massage unit 9 is repeatedly raised and lowered while the neck is pinched by the first massage mechanism, it is as if the masseuse attaches one hand and fixes the neck with the other hand. You can get the feeling of rubbing or stretching the treated area.

In the operation 7, the position where the massage units 8 and 9 are arranged is not particularly limited. Further, the massage mechanism that sandwiches the treated portion and the massage mechanism that raises or lowers the treated portion can be appropriately selected.
