That is, the above-described elevating motor 8, reduction unit 14, elevating shaft 15, and elevating gear 5 constitute an elevating mechanism that elevates and lowers massage mechanism 2.

Next, the massage massage mechanism 9, the tapping massage mechanism 10, and the elevating mechanism provided in the massage device 1 of the present invention will be described.
As shown in FIG. 3, the massaging massage mechanism 9 has a treatment element 17 for treating the treatment section of the user at the distal end side of a pair of left and right arm members 16 provided so as to protrude forward. By oscillating the respective treatment elements 17 in the left-right direction (approaching and moving away from each other), a massage massage is performed on the treatment section.

  The massaging massage mechanism 9 includes a rotating shaft 12 disposed so as to direct the axis in the left-right direction, and an inclination that rotates integrally with the rotating shaft 12 and orbits about an axis inclined with respect to the axis of the rotating shaft 12. An inclined boss 19 having a cam surface 18. The base end of the arm member 16 is rotatably fitted to the inclined cam surface 18 of the inclined boss 19. Further, on the base end side of the arm member 16, there is provided a restricting means 20 for restricting the arm member 16 from rotating around the inclined boss 19. That is, the above-described rotating shaft 12, the inclined boss 19, the arm member 16, the treatment element 17, and the regulating means 20 constitute the kneading massage mechanism 9 of the present invention.

  Specifically, the above-described rotating shaft 12 is a shaft provided in the middle of the massage mechanism 2 in the up-down direction, and is provided so as to be oriented in the left-right direction. Bearings 21 are provided on the middle side and the left end side of the rotating shaft 12 in the left-right direction, and the rotating shaft 12 is supported by these bearings 21 so as to be rotatable around an axis extending in the left-right direction. In addition, the rotational driving force of the power transmission shaft 11 described above is input to the left end side of the rotating shaft 12 in a state of being reduced through the worm gear and the worm wheel.

  On the left end and right end of the rotating shaft 12 (on the left and right sides of the center bearing 21), inclined boss portions 19 that can rotate integrally with the rotating shaft 12 are provided. The inclined boss portions 19 are cylindrical members provided so as to be coaxial with the rotating shaft 12, and the outer peripheral surface of each inclined boss portion 19 is formed around an axis inclined with respect to the axis of the rotating shaft 12. A revolving inclined cam surface 18 is formed.

  Regarding the left and right inclined cam surfaces 18, the inclined directions of the inclined cam surface 18 provided on the left inclined boss portion 19 and the inclined cam surface 18 provided on the right inclined boss portion 19 are opposite. . That is, when the left inclined cam surface 18 is inclined downward left, the right inclined cam surface 18 is inclined downward right, and when the left inclined cam surface 18 is inclined downward right, the right inclined cam surface 18 is inclined downward. The above-described inclined boss portion 19 is attached to the rotating shaft 12 so that the cam surface 18 is inclined downward and to the left.

  As shown in FIG. 5, the arm member 16 includes a treatment element 17 for treating the treatment section of the user at a tip protruding from the rear to the front, and by reciprocating the treatment element 17 in the left-right direction. In addition, it is configured to be able to perform massage massage on the treatment section. In the case of the present embodiment, the arm member 16 is a member formed so as to be substantially T-shaped when viewed from the side in the left-right direction, and the tip protruding forward from rear is upward. The treatment element 17 is attached to the upper end and the lower end of the branched upper and lower branches.

  Specifically, as described in detail in FIG. 5, the arm member 16 described above has a thickness of one treatment element 17 from the base end side fitted to the inclined cam surface 18 of the inclined boss portion 19 toward the front. It protrudes to the extent. Then, the treatment element 17 is vertically extended from the protruding tip protruding forward toward the upper part and the lower part, respectively, and the treatment element 17 is attached to the extended tip so as to be rotatable around an axis pointing in the vertical direction. In other words, the arm member 16 protrudes forward about one thickness of the treatment element 17 but does not protrude forward any more, and the thickness along the front-back direction is not more than about two thicknesses of the treatment element 17 at the maximum. It is suppressed to. Therefore, it is possible to make the thickness of the massage device 1 along the front-rear direction thinner and sufficiently cope with a demand for slimness required for a sheet-type or plate-type massage machine.

  The above-described treatment element 17 is a substantially spherical member that is rotatably mounted around an axis that faces in the up-down direction, and when oscillating in the left-right direction, stimulates the treatment section while rolling, and Treatment is possible. Four treatment elements 17 of the present embodiment are provided, one each for the upper and lower sides of the left arm member 16, and one each for the upper and lower sides of the right arm member 16.

  An annular fitting portion 22 is formed on the base end side of the left and right arm members 16 described above. The annular fitting portion 22 penetrates the arm member 16 in the left-right direction and opens in a circular shape, and has an inner diameter larger than the above-described inclined cam surface 18. That is, the annular fitting portion 22 is externally fitted to the inclined cam surface 18 of the inclined boss portion 19 via the bearing 23 so that the arm member 16 is externally fitted rotatably along the inclined cam surface 18. ing.

  The restricting means 20 is a means for restricting the rotation of the arm member 16 integrally with the inclined boss portion 19. The restricting means 20 includes a protruding piece 24 protruding from the base end side of the arm member 16 and a protruding piece 24. And a swing link member 13 that restricts the arm member 16 from rotating integrally with the inclined boss portion 19 by engaging with the inclined boss portion 19. The regulating means 20 will be described in detail in the hitting massage mechanism 10 hereinafter.

  In the above-described massaging massage mechanism 9, the inclined boss portion attached to the rotating shaft 12 so as to rotate integrally with the rotating shaft 12 when the rotating shaft 12 to which the rotational driving force of the power transmission shaft 11 is transmitted rotates around the axis facing the left-right direction. 19 also rotates around the axis in the left-right direction. At this time, an inclined cam surface 18 orbiting around an axis inclined with respect to the axis of the rotating shaft 12 is formed on the outer peripheral surface of the inclined boss portion 19, and the inclined cam surface 18 is provided with an arm via a bearing. The base end side of the member 16 is rotatably fitted to the outside. Therefore, when the inclined boss 19 is rotated, the arm member 16 also attempts to rotate along with the inclined boss 19. However, since the restricting means 20 described above is provided on the base end side of the arm member 16, the arm member 16 does not rotate accompanying the inclined boss portion 19, and the inclined cam surface 18 of the inclined boss portion 19 does not rotate. The arm member 16 repeats swinging in the left-right direction along.

  As described above, since the inclination direction of the inclined cam surface 18 is opposite at the left and right inclined boss portions 19, when the left arm member 16 swings to the left, the right arm member 16 moves to the right. When the left arm member 16 swings to the right and the left arm member 16 swings to the right, the right arm member 16 swings to the left, and the left and right arm members 16 (treatment element 17) repeatedly approach and separate from each other. . Therefore, in the massage massage mechanism 9, if the treatment section of the user is inserted between the left and right treatment elements 17, the massage massage can be performed on the treatment section.

  On the other hand, the beating massage mechanism 10 makes the arm member 16 reciprocately swing in the direction perpendicular to the axis of the rotating shaft 12 by the reciprocating rocking of the protruding piece 24 of the above-described regulating means 20, so that the arm member 16 can be more closely moved than the close-away movement of massage. The reciprocating rocking is performed at a short pitch, and a tapping massage for tapping the treatment section by the treatment element 17 provided at the tip of the arm member 16 is performed. That is, the above-described beating massage mechanism 10 is configured by the treatment element 17 used in the massaging massage mechanism 9, the arm member 16, the projecting piece 24, and the swing link member 13 that swings the projecting piece 24. Has become.

  Specifically, the protruding piece 24 is a member formed to protrude from the base end side of the arm member 16 toward the lower side of the axis of the rotating shaft 12. The projecting piece 24 is formed with a through hole 25 penetrating the projecting piece 24 in the left-right direction, and the swing link member 13 is provided in the through hole 25 so as to penetrate in a loose fit manner. Further, the swing link member 13 is formed in a bar shape elongated in the left-right direction, and is supported so as to be able to swing about an axis in which a middle side in the left-right direction is directed in the up-down direction. Further, a rotational drive force generated by the drive motor 7 is transmitted to the swing link member 13.

  That is, the rotational driving force generated by the driving motor 7 is transmitted to the power transmission shaft 11 arranged so that the axis is oriented in the up-down direction. An eccentric boss portion 26 eccentrically attached to the power transmission shaft 11 is provided at a lower end side of the power transmission shaft 11, and a connecting body 27 is externally fitted to the eccentric boss portion 26. The connecting body 27 has a base end side rotatably fitted to the outer peripheral surface of the eccentric boss portion 26 and a distal end side along the axis of the swinging link member 13. 13 to be slidably fitted.

  Therefore, as shown in FIG. 4, in the beating massage mechanism 10, when the rotational driving force generated by the drive motor 7 is transmitted to the swing link member 13 via the eccentric boss portion 26, the swing massage mechanism 10 The dynamic link member 13 swings back and forth. Then, the swinging link member 13 swinging in the front-back direction swings the protruding piece 24 in the front-back direction, and the protruding piece 24 swings in the front-back direction, so that it is possible to perform a beating massage with the treatment element 17. .

Next, the projecting piece 24, the swing link member 13, the eccentric boss portion 26, and the connecting body 27 that constitute the tapping massage mechanism 10 of the present embodiment will be described in detail.
As shown in FIGS. 2 to 5, the protruding piece 24 is a member that protrudes downward from the base end side of the arm member 16. A reciprocating swing can be made around the facing axis (around the rotating shaft 12). Although the projecting piece 24 of the present embodiment is configured to project downward, the projecting direction of the projecting piece 24 may be upward.

  Specifically, the projecting piece 24 of the present embodiment can engage with the swing link member 13 so as to be movable in the left-right direction. The protruding piece 24 has a columnar first protruding body 28 protruding downward, and a columnar protruding section 28 disposed rearward of the first protruding body 28 at a distance and protruding downward. A second protruding body 29 is provided, and a retaining portion 30 for connecting a front end of the first protruding body 28 and a front end of the second protruding body 29 is provided. The first projecting body 28 and the second projecting body 29 are arranged at a distance in the vertical direction such that the swing link member 13 can be inserted therethrough. That is, if the tip of the first projection 28 and the tip of the second projection 29 are connected by the retaining portion 30, a through hole 25 penetrating the center of the projection 24 in the left-right direction is formed. The swing link member 13 can be inserted in the left-right direction.

  That is, if the swing link member 13 is inserted in the above-described through hole 25 in the left-right direction, the arm member 16 can swing in the left-right direction even if the swing link member 13 is connected. The swing of the arm member 16 in the left-right direction is not hindered by the arm 13. On the other hand, when the swing link member 13 is swung in the front-rear direction, the first protrusion 28 and the second protrusion 29 of the protruding piece 24 contact the swing link member 13 that swings in the front-rear direction. The arm member 16 also reciprocates in the front-rear direction in accordance with the forward and backward swing of the swing link member 13.

  As shown in FIG. 4, the swing link member 13 swings in the front-rear direction about the middle side in the left-right direction, thereby swinging the protruding piece 24 engaged with the swing link member 13 in the front-rear direction. And swing the arm member 16 back and forth. The swing link member 13 has a pivot shaft 31 that supports the swing link member 13 so as to be rotatable around a vertical axis on a halfway side in the left-right direction. The pivot shaft 31 is attached so as to direct the axis in the vertical direction, and is fixed to the above-described casing. That is, the swing link member 13 is configured to alternately swing back and forth between the left end side and the right end side of the halfway side where the pivot shaft 31 is provided, and swing the left end side and the right end side. The link member 13 is engaged with the projecting piece 24.

  As shown in FIG. 4, the eccentric boss portion 26 is a member formed in a disk shape around an axis that faces in the vertical direction, and is attached so as to be eccentric with respect to the axis of the power transmission shaft 11. And is rotatable integrally with the power transmission shaft 11. On the outer peripheral side of the eccentric boss portion 26, a connecting body 27 having an annular connecting hole which is opened in a circular shape at the center is fitted. The annular connection hole has an inner diameter larger than the outer diameter of the eccentric boss portion 26, and is provided on the outer peripheral surface of the eccentric boss portion 26 via a bearing 32 provided between the eccentric boss portion 26 and the outer peripheral surface. Thus, the connecting body 27 is rotatable.

A link member guide hole 33 is formed in the upper end side of the connecting body 27 so as to penetrate in the left-right direction. That is, by inserting the above-described swing link member 13 into the link member guide hole 33, the connecting body 27 engages with the swing link member 13 in a state where the swing link member 13 is allowed to move in the left-right direction. I agree.
Note that a one-way clutch is provided between the eccentric boss portion 26 and the power transmission shaft 11 described above. That is, the power transmission shaft 11 is made rotatable in the forward and reverse directions by the drive motor 7, and when the power transmission shaft 11 rotates in the forward direction, the rotational driving force of the power transmission shaft 11 is transmitted to the eccentric boss portion 26, When the transmission shaft 11 rotates in the opposite direction, the rotational driving force of the power transmission shaft 11 is not transmitted to the eccentric boss portion 26, in other words, the eccentric boss portion 26 is caused to idle with respect to the power transmission shaft 11.

In this way, when the drive motor 7 (power transmission shaft 11) rotates in the forward direction, both the massaging massage mechanism 9 and the tapping massage mechanism 10 operate, and when the drive motor 7 rotates in the reverse direction. Only the massaging massage mechanism 9 is operated, and the massage operation can be selected by switching the rotation direction of the drive motor 7.
When the above-described one-way clutch is used, the eccentric boss portion 26 and the oscillating link member 13 are provided between the connecting body 27 and the oscillating link member 13 in a direction along the axis of the oscillating link member 13. It is preferable to provide a spring member 34 for elastically connecting the members. By providing such a spring member 34, the load on the one-way clutch can be reduced.

  That is, the upper end side of the connecting body 27 protrudes upward to a height exceeding the pivot 31, and the above-described link member guide hole 33 is formed in a portion protruding upward, and The swing link member 13 is inserted through the link member guide hole 33 so as to penetrate in the left-right direction. Further, the above-described spring member 34 is attached in a biased state at a position away from the portion of the swing link member 13 inserted into the link member guide hole 33 by about two thicknesses of the swing link member 13 in the left-right direction. Spring mounting piece 35 is provided.

  That is, the biased spring members 34 are provided on both the right and left sides of the link member guide hole 33, respectively, and the swing link member 13 is connected via the biased spring members 34. It is connected to the body 27. Therefore, even when an excessive force is applied to the above-described one-way clutch, the applied force is transmitted to the spring member 34 through the connecting body 27, and the load is absorbed by the spring member 34 being bent. The load on the one-way clutch can be reduced.

  In other words, when the power transmission shaft 11 is rotated about an axis that faces in the vertical direction, the eccentric boss portion 26 rotates with the power transmission shaft 11 eccentric about the axis of the power transmission shaft 11. Then, the coupling body 27 rotatably fitted to the outer peripheral surface of the eccentric boss portion 26 via the bearing 32 also tries to rotate together with the eccentric boss portion 26. However, the connecting body 27 is movably engaged with the swing link member 13 via the link member guide hole 33 in the left-right direction. Therefore, the connector 27 does not rotate with the eccentric boss portion 26, and the connector 27 reciprocates in the front-rear direction and the left-right direction.

The connecting body 27 is engaged with the left end side of the swing link member 13 while allowing the swinging link member 13 to swing along the front-rear direction. When the reciprocating movement is performed, the swing link member 13 also repeatedly swings in the front-rear direction around the middle side in the left-right direction.
Since the above-described protruding piece 24 is engaged with the left end side and the right end side of the swing link member 13 in a state where the movement is allowed in the left-right direction, the swing link member 13 swings in the front-rear direction. Then, the arm member 16 also swings back and forth, and the treatment element 17 comes into contact with the treatment section at a faster pitch than the operation of the massaging massage, and it is possible to perform a tapping massage on the treatment section.

The lifting mechanism described above raises and lowers the tapping massage mechanism 10 and the kneading massage mechanism 9 in the vertical direction. This elevating mechanism has an elevating motor 8, an elevating shaft 15 to which the elevating gear 5 is attached, and a reduction unit 14 that reduces the rotational driving force of the elevating motor 8 and transmits it to the elevating shaft 15.
Specifically, the elevating motor 8 is a motor provided on the right side of the drive motor 7, and is provided with the drive shaft 8a facing downward. A worm gear is provided on a drive shaft 8a of the lift motor 8, and transmits a rotational driving force generated by the lift motor 8 to a worm wheel of a first reduction shaft 36 whose axis is oriented in the left-right direction.

  The deceleration unit 14 is for transmitting the rotational driving force generated by the elevating motor 8 at a reduced speed. A second reduction shaft 37 and a third reduction shaft 38 are provided. Each of the second reduction shaft 37 and the third reduction shaft 38 is provided with a reduction mechanism constituted by a spur gear, and the rotation drive force generated by the lifting motor 8 is reduced and applied to the lifting shaft 15 in a reduced state. Has communicated.

  The worm wheel that receives the worm gear of the drive shaft 8a of the elevating motor 8 is rotatably provided on the right end side of the rotary shaft 12 in a loosely fitted state. That is, in the massage device 1 of the present embodiment, the function of the first deceleration shaft 36 is shared by the rotating shaft 12 that transmits the driving force for kneading. By providing at least one of the plurality of gears for transmitting the rotational driving force of the elevating motor 8 to the rotating shaft 12, the number of reduction shafts to be installed can be reduced, and the length of the massage device 1 in the vertical direction can be reduced. The length is shortened, which contributes to the slimming of the massage device 1.

Also, near the upper portion on the left side of the base member 6 described above, an impact relieving member 39 (spring member) for relieving the impact so that the impact when the user sits does not directly act on the base member 6 is provided. Is provided.
It should be understood that the embodiments disclosed this time are illustrative in all aspects and not restrictive. In particular, in the embodiments disclosed herein, matters not explicitly disclosed, such as operating conditions and operating conditions, various parameters, dimensions, weight, and volume of components, deviate from the range usually performed by those skilled in the art.
