Description

Technical Field

[0001] The present invention relates to the field of massage apparatuses, and particularly to a treatment mechanism for treating a treatment part and a massage machine equipped with the treatment mechanism. Background Art

[0002] In patent document JP2001112826A, a massage mechanism that mimics the shape of a human hand for massage is disclosed. It has a treatment part that can massage a user's shoulder or the like. The treatment part includes a rotating shaft, a first link and a second link formed by a link mechanism. The first link and the second link are driven by the rotating shaft to face each other in the forward direction to perform forward clamping massage on the treatment part from the front side and the rear side of the person being treated.

[0003] However, in the above massage mechanism, in order to enable the first link and the second link to move in cooperation, a large number of components need to be coordinated. Therefore, it is easy to cause the complication of the overall structure. Moreover, in addition to providing clamping massage, the link mechanism cannot reproduce hand massage actions including kneading massage, and cannot provide a rich massage feeling for the person being treated.

[0087] Next, the treatment mechanism of the embodiment of the present invention will be described with reference to the accompanying drawings.

[0088] (Overall structure of the treatment mechanism)

[0089] As Figures 1 to 4As shown, the treatment device 1 includes: a rotating shaft 10; a first treatment member 11 and a second treatment member 12. The first treatment member 11 and the second treatment member 12 are spaced apart and rotatably arranged on the rotating shaft 10, and have a first massage portion 112 and a second massage portion 122 for massaging the treated part. The first massage portion 112 and the second massage portion 122 are spaced apart and face each other. The first treatment member 11 and the second treatment member 12 are respectively eccentric and inclined with respect to the rotating shaft 10 (that is, the rotation centers of the first treatment member 11 and the second treatment member 12 are not coincident with the rotation center of the rotating shaft 10, and the extending directions of the main bodies of the first treatment member 11 and the second treatment member 12 are inclined with respect to the extending direction of the rotating shaft 10); and a restricting portion 13 that restricts the first treatment member 11 and the second treatment member 12 from rotating along with the rotation of the rotating shaft 10. Moreover, the first treatment member 11 includes: a first main body 111 provided with the first massage portion 112; and a first restricted portion 113 fixed relative to the first main body 111. The second treatment member 12 includes: a second main body 121 provided with the second massage portion 122; and a second restricted portion 123 fixed relative to the second main body 121. And the restricting portion 13 cooperates with the first restricted portions 113 and 123 to restrict the movement of the first restricted portions 113 and 123 in the circumferential direction of the rotating shaft 10, but allows the first restricted portions 113 and 123 to move in the radial direction of the rotating shaft 10 and the extending direction of the rotating shaft 10.

[0090] As Figure 1 shown, the treatment device 1 further includes a driving mechanism 14 that drives the rotating shaft 10 to rotate.

[0091] As Figure 1 shown, the treatment device 1 further includes a support body 19, and the rotating shaft 10 and the driving mechanism 14 are respectively supported by the support body 19. The restricting portion 13 is connected and fixed to the support body 19 through a component (not shown) for example, or may be directly fixed to the support body 19.

[0092] (Support structure of the rotating shaft)

[0093] As Figure 1 shown, the rotating shaft 10 is rotatably supported by the support body 19.

[0094] Here, as Figure 1 shown, the support body 19 is an annular housing surrounding the middle portion in the extending direction of the rotating shaft 10.

[0095] In addition, as Figure 5 shown, the rotating shaft 10 is rotatably supported by the support body 19 via a first bearing 181 and a second bearing 182 arranged at intervals in the extending direction of the rotating shaft 10.

[0096] (The first treatment member and its support structure)

[0097] As described above, the first treatment member 11 includes: a first main body 111 provided with a first massage portion 112; and a first restricted portion 113 fixed relative to the first main body 111.

[0098] Here, as Figure 4 shown, the first main body 111 has a first extension portion, that is, a first plate-like portion 1111, extending in a direction intersecting the rotation axis 10. A protrusion 1112 protruding toward the second treatment member 12 is formed at an end of the first plate-like portion 1111 opposite to the restricted portion 113. In the illustrated example, the protrusion 1112 is formed as a columnar shape that bends back from the end of the first plate-like portion 1111 opposite to the restricted portion 113 toward the rotation axis 10, but is not limited thereto. The first massage portion 112 is provided at the front end of the protrusion 1112.

[0099] In addition, as Figure 4 shown, the first massage portion 112 is detachably provided on the first main body 111 (in the illustrated example, it is sleeved on the front end of the protrusion 1112, but is not limited thereto). And, as Figure 9 shown, the portion of the first massage portion 112 that contacts the treatment portion is spherical. And, as Figure 3 shown, the movement locus T1 of the first massage portion 112 is formed, for example, as a closed shape having a span in the extending direction of the rotation axis 10 greater than a span in the radial direction of the rotation axis 10.

[0100] In addition, as Figure 7 and Figure 8 shown, in the present embodiment, the first restricted portion 113 is integrally formed with the first main body 111. The first restricted portion 113 protrudes from the first main body 111 in a direction away from the first massage portion 112. And, as Figure 7 and Figure 8 shown, the first restricted portion 113 is a cylindrical protrusion protruding from the first main body 111 toward the restricted portion 13.

[0101] In addition, as Figure 1 、 Figures 3 to 5As shown, the first treatment member 11 is eccentric and inclined with respect to the rotation axis 10 via the first cam member 151, and is supported by the rotation axis 10. The first cam member 151 is sleeved on the rotation axis 10 in an eccentric manner with respect to the rotation axis 10. The first cam member 151 includes a first cylindrical portion 1511 sleeved on the rotation axis 10 and a first cover portion 1512. The first cam groove GV1 is formed by the first cylindrical portion 1511 and the first cover portion 1512. The first cylindrical portion 1511 is fixed to the rotation axis 10 and has a first large-diameter portion P11 arranged along the extension direction of the rotation axis 10 and a first small-diameter portion P12 having an outer diameter smaller than that of the first large-diameter portion P11. The first cover portion 1512 has an outer diameter larger than that of the first small-diameter portion P12. The first cover portion 1512 is assembled to the first cylindrical portion 1511 from the side opposite to the first large-diameter portion P11 with respect to the first small-diameter portion P12. The end surface of the first large-diameter portion P11 on the side of the first small-diameter portion P12 is not orthogonal to the extension direction of the rotation axis 10, and the angle A formed by the two is less than 90 degrees. The angle B formed by the end surface of the first cover portion 1512 on the side of the first small-diameter portion P12 and the extension direction of the rotation axis 10 is also less than 90 degrees. In the present embodiment, the angle A is the same as the angle B. That is, the end surface of the first large-diameter portion P11 on the side of the first small-diameter portion P12 and the end surface of the first cover portion 1512 on the side of the first small-diameter portion P12 are opposite and parallel to each other, and both have the same inclination angle with respect to the rotation axis 10. The end surface of the first large-diameter portion P11 on the side of the first small-diameter portion P12 and the end surface of the first cover portion 1512 on the side of the first small-diameter portion P12 constitute the side wall surface of the first cam groove GV1 and constitute the extension direction of the first cam groove GV1. In a state where the first cylindrical portion 1511 is mounted on the rotation axis 10, the outer peripheral surface of the first small-diameter portion P12 is inclined with respect to the rotation axis 10, and the inclination angle is C. The outer peripheral surface of the first small-diameter portion P12 constitutes the bottom surface of the first cam groove GV1. Thus, the first cam groove GV1 is eccentric with respect to the rotation axis 10, and its extension direction and bottom surface are both inclined with respect to the rotation axis 10.

[0102] In addition, as Figure 7 shown, the first main body 111 of the first treatment member 11 has a first through hole TH1 through which the first small-diameter portion P12 of the first cylindrical portion 1511 passes and whose shape matches the first cam groove GV1. The first treatment member 11 is sleeved in the first cam groove GV1 through its first through hole TH1, and the first cylindrical portion 1511 (specifically, the first large-diameter portion P11) and the first cover portion 1512 respectively define both ends of the first small-diameter portion P12 from both sides of the extension direction of the rotation axis 10, thereby constituting the first cam groove GV1.

[0103] (The second treatment member and its supporting structure)

[0104] As described above, the second treatment member 12 includes: a second main body 121 provided with a second massage portion 122; and a second restricted portion 123 fixed relative to the second main body 121.

[0105] Here, as Figure 4 shown, the second main body 121 has a second extension portion, i.e., a second plate-like portion 1211, extending in a direction intersecting the rotation axis 10. The second massage portion 122 is provided at an end of the second plate-like portion 1211 opposite to the restricting portion 113. The second main body 121 has a larger dimension in the radial direction of the rotation axis 10 than the first main body 111.

[0106] In addition, as Figure 4 shown, the second massage portion 122 is integrally formed with the second main body 121. Similar to the first massage portion 112, the portion of the second massage portion 122 that contacts the treated portion is spherical. However, the shape of the second massage portion 122 is different from the shape of the first massage portion 112. As Figure 3 shown, similar to the first massage portion 112, the movement locus T2 of the second massage portion 122 is formed, for example, as a closed shape with a larger span in the extending direction of the rotation axis 10 than in the radial direction of the rotation axis 10. However, the movement locus T2 of the second massage portion 122 is different from the movement locus T1 of the first massage portion 112. And a plurality of second massage portions 122 are arranged along the extending direction of the second plate-like portion 1211.

[0107] In addition, as Figure 4 and Figure 10 shown, the second restricted portion 123 is integrally formed with the second main body 121. The second restricted portion 123 protrudes from the second main body 121 in a direction away from the second massage portion 122. And, as Figure 4 and Figure 10 shown, the second restricted portion 123 is a protrusion protruding from the second main body 121 toward the restricting portion 13.

[0108] In addition, as Figure 1 、 Figures 3 to 5 shown, the second treatment member 12 is eccentrically and inclinedly supported relative to the rotation axis 10 via the second cam member 152 (in Figure 3In the state of [[ID=]], the first treatment member 11 and the second treatment member 12 are roughly formed in a figure-eight shape). The second cam member 152 includes a second cylindrical portion 1521 sleeved on the rotating shaft 10 and a second cover portion 1522. The second cylindrical portion 1521 is fixed to the rotating shaft 10 and has a second large-diameter portion P21 arranged along the extending direction of the rotating shaft 10 and a second small-diameter portion P22 with an outer diameter smaller than that of the second large-diameter portion P21. The second cover portion 1522 has an outer diameter larger than that of the second small-diameter portion P22. The second cover portion 1522 is assembled to the second cylindrical portion 1521 from the side opposite to the second large-diameter portion P21 with respect to the second small-diameter portion P22. The end face of the second large-diameter portion P21 on the side of the second small-diameter portion P22 is not orthogonal to the extending direction of the rotating shaft 10, and the angle D formed by the two is less than 90 degrees. The angle E formed by the end face of the second cover portion 1522 on the side of the second small-diameter portion P22 and the extending direction of the rotating shaft 10 is also less than 90 degrees. In the present embodiment, the angle D is the same as the angle E (in the illustrated example, the angle D is the same as the angle A). That is, the end face of the second large-diameter portion P21 on the side of the second small-diameter portion P22 and the end face of the second cover portion 1522 on the side of the second small-diameter portion P22 are opposite and parallel to each other, and both have the same inclination angle with respect to the rotating shaft 10. The end face of the second large-diameter portion P21 on the side of the second small-diameter portion P22 and the end face of the second cover portion 1522 on the side of the second small-diameter portion P22 constitute the side wall surface of the second cam groove GV2 and the extending direction of the second cam groove GV2. In the state where the second cylindrical portion 1521 is mounted on the rotating shaft 10, the outer peripheral surface of the second small-diameter portion P22 is inclined with respect to the rotating shaft 10, and the inclination angle is F (in the illustrated example, the angle F is the same as the angle C). The outer peripheral surface of the second small-diameter portion P22 constitutes the bottom surface of the second cam groove GV2. Thus, the second cam groove GV2 is eccentric with respect to the rotating shaft 10, and its extending direction and bottom surface are both inclined with respect to the rotating shaft 10.

[0109] In addition, as Figure 4 and Figure 10 shown, the second main body 121 of the second treatment member 12 has a second through hole TH2 through which the first small-diameter portion P22 of the second cylindrical portion 1521 passes and whose shape matches that of the second cam groove GV2. The second treatment member 12 is sleeved in the second cam groove GV2 through its second through hole TH2, and the second cylindrical portion 1521 (specifically, the second large-diameter portion P21) and the second cover portion 1522 define both ends of the second small-diameter portion P22 from both sides of the extending direction of the rotating shaft 10, thereby constituting the second cam groove GV2..

[0110] (Structure of the restricting portion)

[0111] As described above, the restricting portion 13 restricts the first treatment member 11 and the second treatment member 12 from rotating irregularly as the rotating shaft 10 rotates.

[0112] Here, as Figures 1 to 4 shown, the restricting portion 13 includes a first restricting portion 131 and a second restricting portion 132. The first restricting portion 131 has a first guiding groove GD1 for inserting the first restricted portion 113, and the second restricting portion 132 has a second guiding groove GD2 for inserting the second restricted portion 123. When the rotating shaft 10 rotates, the tips of the first restricted portions 113 and 123 move in an arc shape within the first guiding groove GD1 of the first restricting portion 131 and the second guiding groove GD2 of the second restricting portion 132.

[0113] In addition, as Figures 1 to 3 shown, the first restricting portion 131 and the second restricting portion 132 are disposed on both sides of the support body 19 in the extending direction of the rotating shaft 10.

[0114] Here, taking the first restricting portion 131 as an example, the structure of the guiding groove is described, and the cooperative action between the guiding groove and the restricted portion is described. As Figures 1 to 4 shown, the first guiding groove GD1 extends parallel to the rotating shaft 10, that is, the length direction of the first guiding groove GD1 is consistent with the extending direction of the rotating shaft 10. The first restricted portion 113 can slide along the length direction of the first guiding groove GD1. The width direction of the first guiding groove GD1 intersects with the extending direction of the rotating shaft 10 and is orthogonal in this embodiment. The dimension of the width of the first guiding groove GD1 is substantially the same as the dimension of the first restricted portion 113 in this direction. The first restricted portion 113 can slide along the length direction of the first guiding groove GD1 but cannot slide in the width direction of the first guiding groove GD1. In this embodiment, since the width direction of the first guiding groove GD1 is orthogonal to the extending direction of the rotating shaft 10, that is, in the circumferential direction of the rotating shaft 10, the movement of the first restricted portion 113 in the circumferential direction of the rotating shaft 10 can be regulated. When the first treatment member 11 rotates with the rotating shaft 10 via the eccentric cam structure, it does not generate movement in the circumferential direction of the rotating shaft 10. At this time, the first restricted portion 113 moves along the Figure 3 shown arc-shaped movement locus T3.

[0115] In addition, as Figures 1 to 4 shown, the depth direction of the first guiding groove GD1 is in the radial direction of the rotating shaft 10. The first restricted portion 113 is inserted into the first guiding groove GD1. The first guiding groove GD1 restricts the movement of the first restricted portion 113 in the width direction but allows the movement of the first restricted portion 113 in the length direction and the depth direction. The depth of the first guiding groove GD1 in the depth direction is greater than the moving distance of the first restricted portion 113 in the radial direction of the rotating shaft 10 as the rotating shaft 10 rotates. In this embodiment, the first guiding groove GD1 is a through groove, so that there is no need to overly consider the dimensional relationship between the groove depth and the first restricted portion 113, and the degree of freedom during assembly can be increased.

[0116] (Structure of the driving mechanism)

[0117] As shown in Figure 1 、 Figure 5 and Figure 6 the driving mechanism 14 includes a motor 141 and a transmission mechanism 142.

[0118] Here, as shown in Figure 1 the motor 141 is disposed between the first treatment member 11 and the second treatment member 12 in the extending direction of the rotary shaft 10 and extends perpendicular to the rotary shaft 10. The motor 141 has a motor housing 1411 connected to the support body 19 and a drive shaft 1412 supported by the motor housing 1411 to be rotatable, and the drive shaft 1412 extends perpendicular to the rotary shaft 10.

[0119] In addition, as shown in Figure 1 、 Figure 5 and Figure 6 the transmission mechanism 142 transmits the driving force of the motor 141 to the rotary shaft 10 to rotate the rotary shaft 10. The transmission mechanism 142 includes a turbine 1421. The turbine 1421 is mounted on the middle portion of the rotary shaft 10 (the portion between the first bearing 181 and the second bearing 182 in the illustrated example), is received by the support body 19, and meshes with the thread formed on the outer peripheral surface of the drive shaft 1412, thereby transmitting the driving force of the motor 141 to the rotary shaft 10. And the first treatment member 11 and the second treatment member 12 protrude in a direction away from the restricting portion 13 more than the transmission mechanism 142.

[0120] (General operation of the treatment mechanism)

[0121] When the treatment mechanism 1 performs a massage operation, the first massage portion 112 and the second massage portion 122 can repeatedly perform the operation of approaching and then separating from each other. That is, when the first massage portion 112 and the second massage portion 122 approach each other, they respectively approach the treated portion from both sides of the treated portion, thereby applying a force toward the other side to the treated portion from their own sides and gradually clamping the treated portion. When the first massage portion 112 and the second massage portion 122 separate after approaching each other, they respectively move in a direction away from the closest position. Thus, the operations of approaching and moving away from each other are repeatedly performed to perform a massage.
