An elevating motor 6 is operatively connected to an elevating shaft extending along the left-right direction. The elevating motor 6 is operatively connected to the elevating shaft by the rotation transmitting unit R1. The rotation transmission unit R1 includes a bearing unit and a gear mechanism for changing the direction of the rotation axis. The elevating shaft is rotatably supported by the bearing portion B1 and the bearing portion in the rotation transmitting portion R1. The rotation transmitting portion R1 is fixed below the rear surface of the base member component 2B, and the bearing portion B1 is fixed to the left end of the base member component 2C. The elevating motor 6 is a drive source that moves the massage unit 1 up and down. A pinion gear 7 is provided at the left end of the elevating shaft, and a pinion gear 8 is provided at the right end of the elevating shaft. The pinion gear 7 meshes with a rack provided on the guide rail 300B, and the pinion gear 8 meshes with a rack provided on the guide rail 300C. Therefore, the massage unit 1 is moved up and down along the guide rails 300B and 300C by rotating the elevating shaft by driving the elevating motor 6.

  The massage unit 1 further includes a pair of left and right upper treatment elements 9 and 10, a pair of left and right arms AM1 and AM2, a tapping drive mechanism, a massage drive mechanism, and first to fourth flat plate members P1 to P4. . The tapping drive mechanism causes the upper treatment elements 9 and 10 to perform a tapping operation by swinging the upper treatment elements 9 and 10 in the front-rear direction. The kneading drive mechanism causes the upper treatment elements 9 and 10 to perform a kneading operation by eccentrically rotating the upper treatment elements 9 and 10.

  The upper treatment elements 9 and 10 are treatment elements located at the uppermost position in the massage unit 1.

  The tapping drive mechanism includes a tapping motor 11, a gear 12, a tapping shaft 13, a left eccentric rotary member, a right eccentric rotary member, a left protrusion, and a right protrusion. A left eccentric rotating body and a right eccentric rotating body are fixed to the beating shaft 13. At the rear end of the left-side protruding portion extending forward, a through-hole concentric with the beating shaft 13 is provided. When the beating shaft 13 rotates, the left eccentric rotating body rotates while sliding through the through hole of the left protruding portion. At the rear end of the right protruding portion extending forward, a through hole concentric with the beating shaft 13 is provided. When the beating shaft 13 rotates, the right eccentric rotating body rotates while sliding through the through hole of the right protruding portion. The front end of the left protrusion attached to the tapping shaft 13 is connected to the arm AM1 by a left ball joint. The front end of the right protruding portion attached to the beating shaft 13 is connected to the arm AM2 by a right ball joint. When the tapping motor 11 is driven, a driving force is applied to the tapping shaft 13 via the gear 12, and the tapping shaft 13 rotates. With the rotation of the tapping shaft 13, the arms AM <b> 1 and AM <b> 2 swing about a kneading shaft 15 as a pivot.

  The arm AM1 supports the upper treatment element 9, and the arm AM2 supports the upper treatment element 10. The upper treatment element 9 is rotatably attached to the front end of the arm AM1, and the upper treatment element 10 is rotatably attached to the front end of the arm AM2.

  The kneading drive mechanism includes a kneading motor 14, a kneading shaft 15, and an eccentric rotating body. A pair of left and right eccentric rotating bodies are fixed to the kneading shaft 15 extending in the left-right direction. The kneading shaft 15 supports the rear part of the arm AM1 via the left eccentric rotary body, and supports the rear part of the arm AM2 via the right eccentric rotary body. The kneading motor 14 is linked to the kneading shaft 15. When the kneading motor 14 is driven, the kneading shaft 15 rotates, and the pair of left and right eccentric rotating bodies fixed to the kneading shaft 15 also rotates. The arms AM1 and AM2 swing up and down, left and right, and back and forth by the rotation of the pair of left and right eccentric rotating bodies.

  A bearing that rotatably supports the left end of the kneading shaft 15 is disposed inside the first flat plate member P1. In addition, a bearing for rotatably supporting the left end of the beating shaft 13 is also disposed inside the first flat plate member P1.

  A bearing that rotatably supports the right end of the kneading shaft 15 is disposed inside the second flat plate member P2. In addition, a bearing for rotatably supporting the right end of the beating shaft 13 is also disposed inside the second flat plate member P2.

  A bearing portion rotatably supporting an intermediate portion of the kneading shaft 15 is disposed inside the third flat plate member P3. A bearing portion rotatably supporting an intermediate portion of the beating shaft 13 is also disposed inside the third flat plate member P3.

  Since the left end portion, the right end portion, and the middle portion of the kneading shaft 15 are configured to support the kneading drive mechanism at three positions of the kneading shaft 15, the first flat plate member P1 and the second flat plate member P2 have high rigidity. Not required. Therefore, a large case for storing and supporting the massaging drive mechanism becomes unnecessary, and as a result, the size of the massage unit 1 can be reduced.

  At the front end of the third flat plate member P3, the main body of the fourth flat plate member P4 is fixed substantially perpendicular to the third flat plate member P3.

  The fourth flat plate member P4 includes, in addition to the main body portion of the fourth flat plate member P4, a first folded portion extending rearward from the left side of the main body portion of the fourth flat plate member P4, and a rearward portion from the right side of the main body portion of the fourth flat plate member P4. And a second folded portion extending to

  A lower portion of the first folded portion is attached to the base member component 2D so as to be rotatable around the rotation axis AX1, and a lower portion of the second folded portion is attached to the base member component 2E so as to be rotatable around the rotation axis AX1. Note that the rotation axis AX1 is an axis extending along the left-right direction. Therefore, the third flat plate member P3 is attached to the base member via the fourth flat plate member P4 so as to be rotatable around the rotation axis AX1.

  Massage unit 1 further includes connecting rods 16 and 17. The connecting rods 16 and 17 are rod-shaped members extending in the left-right direction, and connect the first flat plate member P1 and the second flat plate member P2. In other words, the massage unit 1 does not include a case for accommodating the kneading drive mechanism and the tapping drive mechanism. Therefore, the first flat plate member P1 and the second flat plate member P2 do not constitute a part of a case that houses the kneading drive mechanism and the tapping drive mechanism.

  The upper portions of the first folded portion and the second folded portion of the fourth flat plate member P4 are non-rotatably attached to the connecting rod 16. Accordingly, it is possible to suppress the position of the third flat plate member P3 from wobbling due to vibration during the operation of the massaging drive mechanism or the tapping drive mechanism.

  The massage unit 1 further includes an advance / retreat shaft 18, pinion gears 19 and 20, and an advance / retreat motor 21. The reciprocating shaft 18 extends along the left-right direction. A pinion gear 19 is fixed on the left side of the reciprocating shaft 18, and a pinion gear 20 is fixed on the right side of the reciprocating shaft 18. The forward / backward motor 21 is linked to the forward / backward shaft 18. The forward / backward motor 21 is linked to the forward / backward shaft 18 by the rotation transmitting unit R2. The rotation transmission unit R2 includes a bearing unit and a gear mechanism for changing the direction of the rotation axis.

  An arc-shaped rack is provided above each of the first flat plate member P1 and the second flat plate member P2. The pinion gear 19 meshes with a rack provided on the first flat plate member P1, and the pinion gear 20 meshes with a rack provided on the second flat plate member P2. With the rotation of the reciprocating shaft 18, the pinion gears 19 and 20 move with respect to the rack while rotating. The movement of the pinion gears 19 and 20 with respect to the rack causes the first flat plate member P1 and the second flat plate member P2 to rotate in the front-rear direction about the rotation axis AX1, and the upper treatment elements 9 and 10 move forward and backward. That is, when the first flat plate member P1 and the second flat plate member P2 rotate in the front-rear direction about the rotation axis AX1, the protrusion amounts of the upper treatment elements 9 and 10 are adjusted.

  The massage unit 1 further includes a pair of left and right lower treatment elements 22 and 23, a support shaft 24, and protrusions 25 and 26. The lower treatment element 22 is rotatably attached to a position shifted leftward from the center in the left-right direction of the support shaft 24. The lower treatment element 23 is rotatably attached to a position closer to the right side from the center in the left-right direction of the support shaft 24. The left end of the support shaft 24 is fixed to the right side surface of a projection 25 projecting forward from the lower left end of the base member component 2A. The right end of the support shaft 24 is fixed to the left side surface of a protruding portion 26 that protrudes forward from the lower right end of the base member component 2B. According to such a structure, the amount of forward projection of the lower treatment elements 22 and 23 with respect to the base member is fixed.

  The lower treatment elements 22 and 23 are treatment elements located at the lowest position in the massage unit 1.

  In the above-mentioned massage unit 1, the lower treatment elements 22 and 23 are attached to the base member independently of the arms AM1 and AM2. In other words, the lower treatment elements 22 and 23 are not affected by the movement of the arms AM1 and AM2 with respect to the base member. This allows the lower treatment elements 22 and 23 to be arranged at desired positions without executing complicated control.

<3. First Modification of Massage Unit>
FIG. 5 is a front perspective view of the massage unit 1 ′ according to the first modification. FIG. 6 is a front perspective view of the massage unit 1 ′ according to the first modification in a state where the protrusion amounts of the upper treatment element and the lower treatment element are increased. In the massage machine 100, the massage unit 1 'according to the first modification may be used instead of the massage unit 1.

  The massage unit 1 'shown in FIGS. 5 and 6 is different from the massage unit 1 shown in FIGS. 2 to 4 only in the support structure of the lower treatment element, and the structure relating to the upper treatment element is the same. . Therefore, description of the structure related to the upper treatment element of the massage unit 1 'shown in FIGS. 5 and 6 will be omitted.

  The arm AM3 supports the lower treatment element 22, and the arm AM4 supports the lower treatment element 23. The arm AM3 includes a bending portion, and a branch portion BR1 that branches from an intermediate portion of the bending portion and extends linearly.

  Each end of the branch portions BR1 and BR2 is connected to a slide member 29 via a shaft 27 extending in the left-right direction.

  The front end of the screw 28 is rotatably attached to the base member parts 2F and 2G. The base member component 2F is fixed to the base member component 2C at a position closer to the left from the center in the left-right direction of the base member component 2C. The base member component 2G is fixed to the base member component 2C at a position closer to the right from the center in the left-right direction of the base member component 2C.

  The slide member 29 moves along the longitudinal direction of the screw 28 by the driving force of the motor 30. That is, the slide member 29 expands and contracts with respect to the front end of the screw 28 along the longitudinal direction of the screw 28.

  When the slide member 29 contracts along the longitudinal direction of the screw 28 with respect to the front end of the screw 28, the amount of protrusion of the lower treatment elements 22 and 23 decreases as shown in FIG. When the screw 28 extends along the longitudinal direction with respect to the front end of the lower treatment element 22, the amount of protrusion of the lower treatment elements 22 and 23 increases as shown in FIG.

  In the above-mentioned massage unit 1 ', the lower treatment elements 22 and 23 are attached to the base member independently of the arms AM1 and AM2. In other words, the lower treatment elements 22 and 23 are not affected by the movement of the arms AM1 and AM2 with respect to the base member. This allows the lower treatment elements 22 and 23 to be arranged at desired positions without executing complicated control.

  In addition, the above-mentioned massage unit 1 ′ can adjust the amount of protrusion of the lower treatment elements 22 and 23, so that it is possible to perform more various treatments for the user than the above-mentioned massage unit 1.

<4. Second Modification of Massage Unit>
Fig. 7 is a front perspective view of a massage unit 1 "according to a second modification. Fig. 8 is a massage unit 1 according to the second modification in a state where the protrusion amounts of the upper treatment element and the lower treatment element are increased. "Is a front perspective view. In the massage machine 100, the massage unit 1 ″ according to the second modification may be used instead of the massage unit 1.

  The massage unit 1 ″ shown in FIGS. 7 and 8 differs from the massage unit 1 shown in FIGS. 2 to 4 only in the support structure of the lower treatment element, and has the same structure related to the upper treatment element. Therefore, description of the structure related to the upper treatment element of the massage unit 1 ″ shown in FIGS.

  The arm AM3 supports the lower treatment element 22, and the arm AM4 supports the lower treatment element 23. The lower treatment element 22 is rotatably attached to one end of the arm AM3, and the lower treatment element 23 is rotatably attached to one end of the arm AM4.

  The other end of each of the arms AM3 and AM4 is provided with a through-hole, and the rotating shaft 31 passes through the through-hole. The other ends of the arms AM3 and AM4 are fixed to the rotation shaft 31.

  A bearing portion rotatably supporting an intermediate portion of the rotating shaft 31 is disposed inside the flat plate member 32. The rotating shaft 31 is rotated by the driving force of the motor 30. When the rotating shaft 31 is at the standard position, the projecting amounts of the lower treatment elements 22 and 23 become small as shown in FIG. 7, and when the rotating shaft 31 is rotated clockwise by a predetermined angle from the standard position as viewed from the left side. 8, the amount of protrusion of the lower treatment elements 22 and 23 increases.

  In the massage unit 1 "described above, the lower treatment elements 22 and 23 are attached to the base member independently of the arms AM1 and AM2. In other words, the lower treatment elements 22 and 23 are attached to the arms AM1 and AM2.

  In addition, the massage unit 1 ″ described above can adjust the amount of protrusion of the lower treatment elements 22 and 23, and thus can perform more various treatments for the user than the massage unit 1 described above.

<5. Operation example of massage machine>
An example of the operation of the massage machine 100 will be described using a case where the massage unit 1 'is mounted on the massage machine 100 as an example.

  It is desirable that the massage machine 100 has first to third operation modes. The first operation mode is an operation mode in which the user is treated using the upper treatment elements 9 and 10 without using the lower treatment elements 22 and 23. The second operation mode is an operation mode in which the user is treated using both the upper treatment elements 9 and 10 and the lower treatment elements 22 and 23. The third operation mode is an operation mode in which the user is treated using the lower treatment elements 22 and 23 without using the upper treatment elements 9 and 10.

  The above-described first to third operation modes can be executed for the upper treatment elements 9 and 10 as the treatment elements located at the uppermost position and the lower treatment elements 22 and 23 as the treatment elements located at the lowermost position. With this configuration, a wide variety of treatments can be performed on the user.

  Hereinafter, a more specific operation example of the massage machine 100 will be described.

  FIG. 9 is a schematic diagram showing a shoulder gripping operation. The shoulder grip operation is an example of an operation that can be realized by executing the second operation mode.

  The shoulder gripping operation is performed in a state in which the massage unit is stopped at a predetermined elevating position so that the upper treatment element is positioned above the user's shoulder and the lower treatment element is positioned below the user's shoulder. This is an operation in which the amount of protrusion of the treatment element and the amount of protrusion of the lower treatment element are simultaneously increased, and the shoulder is sandwiched between the upper treatment element and the lower treatment element. In addition, the protrusion amount of the lower treatment element may be increased after the protrusion amount of the upper treatment element is increased.

  The massage machine equipped with the massage unit 1 cannot adjust the amount of protrusion of the lower treatment element, and therefore cannot perform the above-described shoulder gripping operation. However, even in a massage machine equipped with the massage unit 1, if the lower treatment element protrudes to a certain extent, the upper treatment element and the lower treatment element allow the upper treatment element and the lower treatment element to protrude. Can be realized.

  In a state where the upper treatment element and the lower treatment element perform the operation of pinching the shoulder, the upper treatment element may further perform a kneading operation or a tapping operation. When the upper treatment element performs the kneading operation, it is desirable to limit the kneading operation to the lower half rotation kneading operation so that the operation of pinching the shoulder between the upper treatment element and the lower treatment element is maintained.

  FIG. 10 is a schematic diagram showing the operation of the lower treatment roller. The lower treatment roller operation is an example of an operation that can be realized by executing the third operation mode.

  The lower treatment element roller operation is an operation in which the massage unit is moved up and down and only the lower treatment element functions as a roller in a state where the protrusion amount of the upper treatment element is reduced so that treatment using the upper treatment element is not performed. is there. ADVANTAGE OF THE INVENTION According to the massage machine which concerns on this invention, a roller can be made to reach a user's lower part rather than a massage machine which does not have a lower treatment element.

  FIG. 11 is a schematic diagram showing the upper treatment child massage operation. The upper massager massage operation is an example of an operation that can be realized by executing the first operation mode. The upper treatment element rubbing operation is a rubbing operation performed in a state in which the protrusion amount of the upper treatment element is increased so that the upper treatment element projects from the lower treatment element.

  FIG. 12 is a schematic diagram showing the lower treatment child acupressure operation. The lower treatment element acupressure operation is an example of an operation that can be realized by executing the third operation mode. The lower treatment element acupressure operation is an operation that simulates acupressure such as pushing up from below, and is an operation of increasing or decreasing the amount of protrusion of the lower treatment element.

  Note that the massage machine equipped with the massage unit 1 cannot adjust the amount of protrusion of the lower treatment element, and thus cannot perform the above-described lower treatment element acupressure operation.

  FIG. 13 and FIG. 14 are schematic diagrams showing the back muscle stretching operation. The back stretching operation is an example of an operation that can be realized by repeatedly executing the second operation mode and the third or first operation mode.

  The back stretching operation is performed in a state where the massage unit is stopped at a predetermined elevating position so that the upper treatment element and the lower treatment element face the back of the user, and the upper treatment element and the lower treatment are performed as shown in FIG. From the first state in which the back of the practitioner is pressed by both of the children, the state is switched to the second state in which the back of the practitioner is pressed only by the lower treatment element by increasing the protrusion amount of the lower treatment element, for example. This is an operation of repeating a routine of reducing the amount of protrusion of the lower treatment element and returning to the first state.

  In order to prevent the treatment for stretching the back muscle from being hindered by gravity, the back stretching operation is desirably performed in a state where the backrest of the massage machine is lying down.

  FIG. 15 is a schematic diagram showing the buttocks grasping operation. The buttocks grasping operation is an example of an operation that can be realized by executing the second operation mode. The ass grasping operation is in a state where the massage unit is stopped at a predetermined elevating position so that the upper treatment element faces the upper part of the user's buttocks and the lower treatment element faces the lower part of the user's buttocks, This is an operation in which the protrusion amount of the upper treatment element and the protrusion amount of the lower treatment element are simultaneously increased, and the buttocks are sandwiched between the upper treatment element and the lower treatment element. In addition, the protrusion amount of the lower treatment element may be increased after the protrusion amount of the upper treatment element is increased.

  The massage machine equipped with the massage unit 1 cannot adjust the amount of protrusion of the lower treatment element, and thus cannot perform the above-described original buttocks gripping operation. However, even in a massage machine equipped with the massage unit 1, if the lower treatment element protrudes to a certain extent, the protrusion amount of the upper treatment element is increased so that the upper treatment element and the lower treatment element cause the lower treatment element to protrude. The operation of sandwiching the part can be realized.

  In a state where the upper treatment element and the lower treatment element perform the operation of sandwiching the buttocks, the upper treatment element may further perform a kneading operation or a tapping operation. In addition, when the upper treatment element performs the kneading operation, it is desirable to limit the kneading operation to the lower half rotation kneading operation so that the operation of sandwiching the buttocks by the upper treatment element and the lower treatment element is maintained. .

  FIG. 16 and FIG. 17 are schematic views showing the raising and lowering operation. The gripping / lowering operation is an example of an operation that can be realized by executing the second operation mode.

  The grasping and lowering operation is an operation of pulling while grasping the shoulder. In a state where the upper treatment element and the lower treatment element sandwich the shoulder, the massage unit is raised from the third state shown in FIG. This is an operation of repeating a routine of switching to the fourth state shown in FIG. 17 and then lowering the massage unit to return to the third state. In addition, it is desirable to change the protrusion amount of the upper treatment element in conjunction with the elevation of the massage unit so that the operation of pinching the shoulder between the upper treatment element and the lower treatment element is maintained.
