It is a part located in the lower part of the up-down direction from the rotating shaft 11 arranged in the direction.

The first treatment part 9 is formed in a shape that is curved along the shape of the calf from the upper side to the lower side, and the second treatment part 10 is formed in a shape that wraps inwardly from the rear to the front (along the foot shape). A curved shape).
A rotating shaft 11 passes through the base end portion 8 (bent portion) of each treatment member 7, and the rotational driving force of the rotating shaft 11 is sandwiched in the lower limb F by the treatment member 7 in the penetrating portion. A conversion unit 13 is provided for converting into an operation or a rocking massage operation.

Next, the structure of the conversion unit 13 will be described.
FIG. 4 is a front sectional view of the conversion unit 13 provided on the treatment member (the right outer treatment member 7a) that contacts the right leg F from the outside in the width direction. FIG. 5 is a plan sectional view of the conversion unit 13 provided in the right outer treatment member 7a. The conversion unit 13 shown in FIGS. 4 and 5 will be described as an example.

The conversion unit 13 has substantially the same structure as the conversion unit 13 provided in other treatment members (the right inner treatment member 7b, the left outer treatment member 7c, and the left inner treatment member 7d).
As shown in FIGS. 4 and 5, the conversion unit 13 includes a rotary boss portion 14 fixed to an intermediate portion in the axial direction of the rotary shaft 11 so as to rotate integrally with the rotary shaft 11 via a switching unit 21 described later. An annular fitting portion 16 that is externally fitted to the rotating boss portion 14 through a bearing 17 in a relatively rotatable state, and a regulating portion that restricts the annular fitting portion 16 from rotating around the rotating boss portion 14. 18.

  First, as shown in FIGS. 4 and 5, the rotating boss portion 14 is a disk-shaped member provided with respect to the rotating shaft 11, and an endless track (cam surface 15) is provided on the outer peripheral portion thereof. The cam surface 15 is formed so as to be inclined with respect to the axis of the rotary shaft 11. An inner race of the bearing 17 is fitted into the cam surface 15. An annular fitting portion 16 is fitted into the outer race of the bearing 17.

  An opening portion having a diameter slightly larger than the size of the rotating boss portion 14 is formed at the base end portion 8 of the treatment member 7 a, and the periphery of the opening portion is an annular fitting portion 16. The annular fitting portion 16 is substantially annular in a side view and is integrally formed with the treatment member 7a. The annular fitting portion 16 (periphery of the opening formed in the treatment member 7 a) is fitted on the outer race of the bearing 17 fitted on the cam surface 15. Due to such a structure, the rotating boss portion 14 and the annular fitting portion 16 are relatively rotatable.

  Further, as shown in FIG. 5, the restricting portion 18 is provided on the rear wall 2 c of the casing 2 and protrudes forward in a sliding guide groove 19 that extends to the left and right provided on the rear side of the annular fitting portion 16. The restricting protrusion 20 is slidably inserted in the width direction. The regulation protrusion 20 slides left and right in the sliding guide groove 19 so that the treatment member 7 a and the rotating shaft 11 do not rotate.

  According to the conversion unit 13 having the above-described configuration, when the rotating shaft 11 rotates, the rotating boss portion 14 tries to rotate integrally with the rotating shaft 11 via the switching unit 21 described later. However, due to the function of the restricting portion 18, the annular fitting portion 16, that is, the treatment member 7a, swings only in the left-right direction without rotating integrally. This rocking motion is a sandwich massage operation or a rocking massage operation for the lower limbs F.

By the way, the conversion unit 13 is provided with switching means 21 that is a feature of the present invention.
The switching means 21 switches the pair of treatment members 7 between a reverse phase swing (pinching massage operation) and an in-phase swing (oscillation massage operation).
As shown in FIGS. 3 and 4, the switching means 21 of the present embodiment is provided in the conversion portion 13 of the right outer treatment member 7 a and the left outer treatment member 7 c. The switching means 21 may be provided in the conversion part 13 of the right outer treatment member 7a and the left outer treatment member 7c.

First, the reverse-phase swing operation and the in-phase swing operation of the pair of treatment members 7 will be described.
As shown in FIG. 8 (a), the reverse-phase swinging of the pair of treatment members 7 causes the right inner treatment member 7b and the right outer treatment member 7a to repeatedly approach and separate, and the user's right lower limb F ( The massage part is sandwiched and massaged. Further, the reverse-phase swinging of the pair of treatment members 7 is such that the left inner treatment member 7d and the left outer treatment member 7c repeat approaching and separating to sandwich the left lower limb F (treatment portion) of the user. Is to do.

  Formed on the rotating boss portion 14 (the rotating boss portion 14 into which the inner treatment members 7b and 7d are fitted and the rotating boss portion 14 into which the outer treatment members 7a and 7c are fitted) when the treatment member 7 is swung in reverse phase. The endless orbits thus formed are inclined in different directions so as to form a mirror image with respect to a line perpendicular to the rotation axis 11. Therefore, as shown in FIGS. 3 and 8A, the treatment member 7 at the time of reverse-phase oscillation has a vertical extension line of the inner treatment member 7 and a vertical extension line of the outer treatment member 7 as shown in FIG. Thus, a state of crossing is performed, and “pinching massage” is performed so as to pinch the user's lower limbs F inserted into the pair of treatment recesses 3.

  On the other hand, as shown in FIG. 8C, the rotating boss portion 14 (the rotating boss portion 14 into which the inner treatment member 7 fits and the outer treatment member 7 fit into when the treatment member 7 performs in-phase swinging). The endless tracks formed on the rotating boss portion 14) are inclined with respect to the rotating shaft 11 in substantially the same direction. Therefore, the treatment member 7 at the time of in-phase swinging moves the lower limb F of the user inserted into the pair of treatment recesses 3 in the left-right direction while the inner treatment member 7 and the outer treatment member 7 are maintained in a substantially parallel state. “Oscillating massage” is performed.

The massage machine 1 of the present invention realizes the above-described reverse-phase swing (pinching massage operation) and in-phase swing (oscillation massage operation) by the switching means 21.
The switching means 21 will be described in detail below.
FIG. 6 is an enlarged cross-sectional view of the switching means 21 provided in the rotating boss portion 14 in which the right outer treatment member 7a is fitted. The switching means 21 having the same structure is also provided in the rotating boss portion 14 into which the left outer treatment member 7c is fitted.

As shown in FIG. 6, the switching means 21 is provided inside a cylindrical hole 22 opened in the center of the rotating boss portion 14, and is provided with an engaging portion 24 a (rib 24) and an engaging portion 24 a. It has the protrusion 25 (pin body) to engage.
This switching means 21 is switched to either a pinching massage or a rocking massage by engaging a projection 25 provided on the rotating shaft 11 with an engaging portion 24a provided on the rotating boss portion 14. It consists of a "rotating clutch mechanism".

As shown in FIG. 6, the switching means 21, that is, the half-rotation clutch mechanism, has a protrusion 25 provided on the rotary shaft 11 when the rotary shaft 11 rotates and rotates (rotates 180 °). It is configured to rotate with the rotational drive and engage with the engaging portion 24a.
First, the rotating boss part 14 provided with the engaging part 24a will be described.
As described above, the rotating boss portion 14 is a disk-shaped plate material, and a bottomed cylindrical hole 22 having a larger diameter than the rotating shaft 11 is opened at the center of the left side wall 2d of the rotating boss portion 14. . On the opening side of the hole 22, a cap 26 that restricts the rotating boss portion 14 from moving left and right is fitted. A through hole 23 through which the rotating shaft 11 passes is formed at the bottom center of the bottomed cylindrical hole 22 (center of the rotating boss portion 14).

  The rotating shaft 11 is inserted into the through hole 23, and the rotating shaft 11 slides and rotates (does not rotate integrally) with respect to the through hole 23. Further, a rib 24 is erected on the bottom portion of the hole 22 so as to extend along the rotation shaft 11 inserted into the through hole 23 in a direction (left direction) from the bottom portion toward the opening of the hole 22. The rib 24 is provided so as to surround the outer edge of the through hole 23 over a half circumference of the outer edge of the through hole 23.

When viewed from the opening side of the hole 22 provided in the rotating boss portion 14, the rib 24 has a C shape along the outer periphery of the rotating shaft 11 inserted through the through hole 23, and extends along the outer periphery of the rotating shaft 11. The portion where the C-shaped rib 24 does not exist is a space (movement space) in which a projection 25 described later can move around the axis of the rotary shaft 11.
The end surfaces of the ribs 24 (boundary surfaces between the moving space and the ribs 24) are formed at positions facing each other around the axis of the rotating shaft (positions different by 180 ° in the circumferential direction around the axis of the rotating shaft 11). That is, the plane formed by the two end faces of the rib 24 is substantially parallel to the axis of the rotating shaft 11.

Two end surfaces of the rib 24 serve as an engaging portion 24 a that engages a protrusion 25 provided on the rotating shaft 11, and the engaging portion 24 a rotates as the rotating shaft 11 rotates. Is controlled so as not to rotate more than 180 ° around the axis of the rotary shaft 11.
That is, the engaging portion 24 a is engaged with the protrusion 25 rotated around the axis of the rotating shaft 11 by contacting the end surface of the rib 24.

Next, the protrusion 25 provided on the outer peripheral surface of the rotating shaft 11 will be described.
The protrusion 25 is a member formed in a columnar shape, and is provided so as to protrude from the outer peripheral surface of the rotating shaft 11 in the radially outward direction (perpendicular to the axis of the rotating shaft 11). The protrusion 25 has a protrusion length between the outer peripheral surface of the rotating shaft 11 and the inner peripheral surface of the cylindrical hole 22 formed in the rotating boss portion 14, and the inner peripheral surface of the cylindrical hole 22. Is not touching. Further, the width of the protrusion 25 in the left-right direction (the width along the axis of the rotating shaft 11) is substantially the same as the width of the end face of the rib 24, so that it can be reliably engaged with the engaging portion 24a. .

In summary, the switching means 21 is provided with a pair of engaging portions 24 a in a cylindrical hole 22 opened in the rotating boss portion 14 at a position different by 180 ° in the circumferential direction around the axis of the rotating shaft 11. On the opposite side (moving space) of the engaging portion 24a, the protrusion 25 is stored so as to be movable around the axis of the rotating shaft 11.
Hereinafter, the operation of the switching means 21 (half-rotation clutch mechanism), that is, a method of switching between the pinching massage of the pair of treatment members 7 and the swing massage will be described.

  FIG. 7 is a diagram illustrating the operation of the switching unit 21. FIG. 7A is a view showing a state in which the protrusion 25 of the switching means 21 is engaged with one of the engaging portions 24a, and FIG. FIG. 7C is a view showing a state in which the projection 25 of the switching means 21 is engaged with the other engagement portion 24a. .

FIG. 8 is a view showing the operation of the pair of treatment members 7 arranged on the left and right. FIG. 8A is a diagram illustrating the state of the sandwich massage, and FIG. 8B is a diagram illustrating a state in the middle of switching from the sandwich massage state to the rocking massage state. c) is a diagram showing a state of rocking massage.
First, in the massage machine 1 of this embodiment, about the operation | movement which switches to the rocking | fluctuation massage from the state in which the pair of right and left treatment members 7 are sandwiched and massaged with respect to the user's lower limb F inserted into the treatment recess 3. It demonstrates based on a figure.

In describing the operation of switching from the sandwich massage state to the rocking massage state, the switching means 21 is disposed in the right outer treatment member 7a, and the left outer treatment member 7c is a conversion portion. A description will be given assuming that each of 13c is provided.
In the state where the sandwich massage is performed as shown in FIG. 8 (a), as shown in FIG. 7 (a), the switching means 21 has a protrusion 25 provided on the rotating shaft 11 and an engaging portion 24a on one side. It is in a state of being engaged (under the paper).

At this time, the rotary shaft 11 is rotationally driven from the rear side toward the front side, and the rotary boss portion 14 through which the rotary shaft 11 passes rotates from the rear side toward the front side as the rotary shaft 11 rotates. doing. That is, the rotating shaft 11 and the rotating boss portion 14 are in a rotating state.
Then, the annular fitting portion 16 that is externally fitted to the rotating boss portion 14 via the bearing 17 in a relatively rotatable state tends to be provided in the same direction as the rotating boss portion 14. However, the regulation protrusion 20 provided on the rear wall 2c so as to protrude forward in the sliding guide groove 19 provided on the rear side of the annular fitting portion 16 (the treatment member 7) slides in the width direction. Since it fits freely, the rotation is restricted.

  Therefore, as shown in FIG. 8A, the right outer rotating boss portion 14a and the right inner rotating boss portion 14b have cam surfaces 15 provided on the rotating boss portions 14a and 14b as the axis of the rotating shaft 11, respectively. The pair of treatment members 7 that are inclined in different directions with respect to the rotation boss portions 14 a and 14 b are moved in opposite phases to the left and right as the rotary shaft 11 is driven to rotate. It has become.

  That is, when the upper part of the right outer treatment member 7a moves to the left side, the upper part of the right inner treatment member 7b moves to the right side. Conversely, when the upper part of the right outer treatment member 7a moves to the right side, The upper part of the inner treatment member 7b moves to the left. This movement is the same in the lower part of the treatment member 7, and the upper part of the right outer treatment member 7a and the upper part of the right inner treatment member 7b are moved closer to and away from each other, and in conjunction with this, the right outer treatment member The lower part of 7a and the lower part of the right inner treatment member 7b separate and approach each other.

Next, the “switching massage” in which the lower limbs F are sandwiched from the left and right directions is switched to “oscillation massage (open / close swinging massage)” in which the left and right lower limbs F are twisted to open and close each other.
As shown in FIG. 7B, the drive direction of the drive motor of the drive unit 12 is switched to rotate the rotating shaft 11 in the reverse direction (from the front side toward the rear side). Then, in the switching means 21 (conversion unit 13), the protrusion 25 provided on the rotating shaft 11 is separated from the engaging portion 24a on one side by 180 ° with the rotation (reverse rotation) of the rotating shaft 11. It rotates around the axis of the rotary shaft 11 toward the other engagement portion 24a (upper side of the paper surface).

At this time, the rotating shaft 11 is rotationally driven from the front side toward the rear side, but the right outer rotating boss portion 14a through which the rotating shaft 11 passes is in a stopped state. That is, the rotating shaft 11 is in a state of idling with respect to the right outer rotating boss portion 14a. Therefore, the right outer treatment member 7a is also stopped (inclined to the drive side of the massage machine 1).
As shown in FIG. 8 (b), the treatment member 7 b on the right inner side is connected to the rotary shaft 11 and the rotary boss portion 14 so as to be relatively rotatable with each other. 1 from the drive unit 12 side to the outside (from the right side to the left side of the massage machine 1).

When the right inner treatment member 7b finishes inclining to the inner side (drive unit 12) of the massage machine 1, the right inner treatment member 7b is arranged in parallel with the right outer treatment member 7a. Specifically, the right inner treatment member 7 b and the right outer treatment member 7 a are arranged to be inclined toward the inner side of the massage machine 1.
As shown in FIG. 8 (c), when the right inner treatment member 7b has finished inclining to the inside (drive unit 12) of the massage machine 1, the switching means 21 rotates the rotation axis as shown in FIG. 7 (c). 11 is engaged with the engaging portion 24a on the other side.

When the protrusion 25 engages with the other engaging portion 24a, the right outer rotating boss portion 14a moves from the front side toward the rear side along with the rotating shaft 11 that is driven to rotate from the front side toward the rear side. It starts to rotate. That is, the rotating shaft 11 and the outer right rotating boss portion 14a are rotated.
Then, the annular fitting portion 16 that is externally fitted to the right outer rotary boss portion 14a through the bearing 17 in a relatively rotatable state tends to rotate in the same direction as the right outer rotary boss portion 14a.
