In addition, in FIGS. 5 and 6, the upper treatment child 521 and the lower treatment child 522 of the treatment unit 52 and the body Bd of the treated person are in direct contact with each other, but in reality, the upper treatment child 521 and the lower side are in contact with each other. A cover member (not shown) is interposed between the side treatment child 522 and the body Bd of the treated person.

The massage unit 50 has a base member 51 and a pair of treatment units 52 arranged on the base member 51.

<Base member 51>
The base member 51 has a left base member component 51A, a right base member component 51B, a lower connection base member component 51C, and an upper connection base member component 51D. The left base member component 51A and the right base member component 51B have a rectangular shape when viewed from the front, and the vertical length is longer than the horizontal length.

The lower connection base member component 51C connects the lower end of the left base member component 51A and the lower end of the right base member component 51B. The upper connection base member component 51D is a columnar member whose center is bent, and connects the upper end of the left base member component 51A and the upper end of the right base member component 51B. Further, the left end of the upper connecting base member component 51D projects to the left of the left base member component 51A, and the right end projects to the right of the right base member component 51B.

<Pair treatment unit 52>
The pair of treatment units 52 are arranged symmetrically. Here, the treatment unit 52 arranged on the left side will be used for explanation. When it is necessary to distinguish a pair of treatment units 52, they are referred to as a treatment unit 52 on the left side and a treatment unit 52 on the right side. Similarly, when distinguishing the constituent parts constituting the pair of treatment portions 52, they are distinguished as the left side or the right side.

The treatment unit 52 has a support plate 520, an upper treatment element 521, a lower treatment element 522, and a rotation actuating unit 54.

The support plate 520 is rotatably attached to the base member 51 around a rotation axis Ax extending in the left-right direction. Specifically, the support plate 520 is arranged on the base member 51 and rotatably attached to a shaft extending along the rotation axis Ax. More specifically, the support plate 520 is integrally formed and has a tubular portion 525 extending in the thickness direction (see FIG. 4 and the like). The tubular portion 525 is rotatably arranged on the outside of the shaft. At this time, the center line of the tubular portion 525 and the center of the shaft coincide with the rotation axis Ax. As a result, the support plate 520 is rotatably supported by the base member 51 about the rotation axis Ax.

The support plate 520 is a flat plate having a substantially L-shape in a side view. In the direction along the flat plate of the support plate 520, the direction toward one of the bifurcations forming the L-shape is defined as the first direction. Further, the direction toward the other side of the bifurcation forming the L-shape is defined as the second direction. Further explaining, the first direction is a direction along the flat plate of the support plate 520, the first direction is upward from the rotation axis Ax, and the second direction is a constant angle from the rotation axis Ax to the first direction. , For example, in the direction of forming a right angle.

The support plate 520 has an upper arm portion 523 extending in the first direction and a lower arm portion 524 extending in the second direction. Then, the upper treatment child 521 is arranged on the upper arm portion 523. Further, a lower treatment child 522 is arranged on the lower arm portion 524.

The upper treatment element 521 and the lower treatment element 522 attached to the support plate 520 are arranged apart from each other in the circumferential direction about the rotation axis Ax. The upper treatment child 521 is arranged above the lower treatment child 522.

The upper treatment element 521 and the lower treatment element 522 are rotating bodies centered on the central axis Bx extending in the direction along the rotation axis Ax. The rotating body centered on the central axis Bx is a solid formed when a figure arranged on a plane including the central axis Bx is rotated around the central axis Bx. Further, in the present embodiment, the central axis Bx is parallel to the rotation axis Ax, but it does not have to be parallel. The upper treatment child 521 and the lower treatment child 522 come into contact with the body of the treated person to perform treatment such as kneading and tapping on the treated person.

The rotation actuating portion 54 reciprocates the support plate 520 between the first position P1 and the second position P2 different from the first position P1. Further, the rotation operating portion 54 applies a force to the support plate 520 in the direction in which the support plate 520 rotates around the rotation axis Ax. The first position P1 and the second position P2 are the positions of both ends rotated around the rotation axis Ax, respectively.

Further explaining, the first position P1 is a position where the upper arm portion 523 of the support plate 520 is rotated backward and the upper treatment child 521 and the lower treatment child 522 are in contact with the body Bx of the treated person (FIG. 5). Etc.), that is, a two-point support position. Further, in the second position P2, the upper arm portion 523 of the support plate 520 is rotated forward, and only the upper treatment child 521 is in contact with the body Bx of the treated person (see FIG. 6), that is, one point. It is a support position.

The rotation actuating portion 54 has an elastic member 541 and an expansion / contraction portion 542. The elastic member 541 is, for example, a torsion spring and is attached to the outer peripheral surface of the tubular portion 525. Further, as shown in FIGS. 4 to 6, one end of the elastic member 541 engages with the engaging convex portion 501 of the base member 51, and the other end engages with the engaging portion 526 of the support plate 520. It fits. The engaging convex portion 501 and the engaging portion 526 are bolts (screw members) attached to the base member 51 and the support plate 520, respectively, but are not limited thereto. A configuration in which the end portion of the elastic member 541 can be engaged can be widely adopted. As a result, the elastic member 541 imparts an elastic force to the support plate 520 to rotate the support plate 520 toward the first position P1.

The expansion / contraction portion 542 expands when compressed air is supplied from an air compressor (not shown), and contracts when air is removed. That is, the expansion / contraction portion 542 is a bag body (so-called airbag) that can be repeatedly expanded and contracted by air. The expansion / contraction portion 542 is fixed to the base member 51. Further, the expansion / contraction portion 542 is formed on the support plate 520 and comes into contact with the pressing portion 527 for pushing down the support plate 520. The expansion / contraction portion 542 has a side view fan shape, and by expanding, the central angle of the fan shape is widened. When expanding, the expansion / contraction portion 542 pushes the pressing portion 527 of the support plate 520 toward the second position P2. In other words, the expansion / contraction portion 542 can apply a force to rotate the support plate 520 toward the second position P2 by expansion due to air to the support plate 520.

The massage unit 50 further includes a treatment drive mechanism 503. The treatment drive mechanism 503 drives a pair of treatment units 52 to perform treatment such as kneading and tapping on the body of the person to be treated who is in contact with the pair of treatment units 52.

The massage unit 50 has guide rollers 61 and 62. The guide roller 61 and the guide roller 62 are rotatably supported at both ends of the base member component 51D, respectively. The guide roller 61 slides on the guide rail 13 when the massage unit 50 moves up and down, and the guide roller 62 slides on the guide rail 14 when the massage unit 50 moves up and down.

Further, the massage unit 50 further includes pinion gears 63 and 64. The pinion gear 63 meshes with the rack provided on the guide rail 13, and the pinion gear 64 meshes with the rack provided on the guide rail 14. The pinion gears 63 and 64 are rotationally driven by an elevating motor arranged in the massage unit 50. The rotation of the pinion gear 63 and the pinion gear 64 causes the massage unit 50 to move up and down along the guide rails 13 and 14.

<About the operation of the treatment department>
The support plates 520 of the pair of treatment portions 52 are rotated around the rotation axis Ax by the rotation actuating portion 54, respectively. As described above, when air is discharged from the inside of the expansion / contraction portion 542 and the support plate 520 contracts, the elastic force of the elastic member 541 acts on the support plate 520 in the direction of rotating the support plate 520 toward the first position P1. As a result, the support plate 520 moves to the first position P1. When the support plate 520 moves to the first position P1, it comes into contact with the first stopper 51E provided on the base member 51 and stops at the first position P1 (see FIG. 5).

As shown in FIG. 5, when the support plate 520 is in the first position P1, the upper treatment child 521 and the lower treatment child 522 of the treatment unit 52 are likely to come into contact with the body Bd of the treated person at the same time. As a result, the area of the treatment unit 52 in contact with the body Bd of the person to be treated can be increased, and an increase in contact pressure can be suppressed.

Further, by supplying compressed air from an air compressor (not shown) to the expansion / contraction portion 542, the expansion / contraction portion 542 expands. As a result, a force that rotates the support plate 520 from the expansion / contraction portion 542 toward the second position P2 acts on the pressing portion 527 of the support plate 520. The force with which the expansion / contraction portion 542 pushes the pressing portion 527 is larger than the elastic force of the elastic member 541. Therefore, as the expansion / contraction portion 542 expands, the support plate 520 is rotated to the second position P2, comes into contact with the second stopper 51F, and stops at the second position P2 (see FIG. 6).

As shown in FIG. 6, when the support plate 520 is in the second position P2, the upper treatment child 521 of the treatment unit 52 protrudes forward from the lower treatment child 522. Therefore, when the support plate 520 is in the second position, the upper treatment child 521 tends to come into contact with the body Bd of the treated person. As a result, the area of the treatment unit 52 in contact with the body Bd of the person to be treated can be reduced, and the contact pressure can be increased.

In the massage unit 50, the left and right support plates 520 may operate so as to be in the first position P1 or the second position P2 at the same time. By operating in this way, when the left and right support plates 520 are in the first position P1, they come into contact with the body Bd of the treated person at four points of the left and right upper treatment child 521 and the left and right lower treatment child 522. Further, when the left and right support plates 520 are in the second position P2, they come into contact with the body Bd of the treated person at two points of the left and right upper treatment elements 521.

FIG. 7 is an enlarged side view of the massage machine 100 in which the guide rail 14 and the massage unit 50 are enlarged. As shown in FIG. 7, the upper portion 131 of the guide rail 13 is arranged on the backrest portion 12, and the lower portion 132 is arranged on the rear portion of the seat portion 11. Although not shown, the guide rail 14 has a similar configuration. The massage unit 50 moves up and down inside the backrest portion 12 along the guide rails 13 and 14. Then, the massage unit 50 moves from the lower part of the backrest portion 12 to the rear portion of the seat portion 11.

In the massage machine 100 according to the present embodiment, when the massage unit 50 is on the backrest portion 12, the left and right support plates 520 are moved to the second position P2. As a result, the two points of the left and right upper treatment elements 521 come into contact with the body Bd of the treated person.

Further, when the massage unit 50 is located at the rear of the seat portion 11, the left and right support plates 520 are moved to the first position P1. As a result, the left and right upper treatment child 521 and the left and right lower treatment child 522 come into contact with the body Bd of the treated person at four points.

That is, in the massage unit 50, the pair of support plates 520 is located at the second position P2 when in contact with the back of the treated person, and the pair of support plates 520 is located at the first position P1 when in contact with the thigh of the treated person. Located in.

As described above, in the backrest portion 12 where the force received by the massage unit 50 from the treated person is small, the massage unit 50 comes into contact with the body Bd of the treated person at two points, and the left and right upper treated children 521 act on the back of the treated person. The pressure to massage can be increased. Further, in the seat portion 11 in which the massage unit 50 supports the treated person from below, pressure is applied because the massage unit 50 comes into contact with the body Bd of the treated person at four points of the left and right upper treatment child 521 and the left and right lower treatment child 522. scatter. Therefore, in the massage machine 100, regardless of the position of the massage unit 50, the treatment can be performed in contact with the body Bd of the person to be treated with a necessary and sufficient pressure.

In the massage unit 50 of the present embodiment, the left and right support plates 520 are pushed by the left and right expansion and contraction portions 542. The left and right swelling portions 542 are formed so as to contract when a certain force or more is applied in the contracting direction in the expanded state. By being formed in this way, for example, when the pressure in contact with the body Bd of the treated person becomes a certain pressure or more due to the reclining of the backrest portion 12, the left and right support plates 520 are in the first position. Move to the P1 side. As a result, the pressure can be dispersed from the two-point support state to the four-point support state. Therefore, the pressure at the time of treatment can be suppressed to a certain level or less, and the discomfort of the treated person due to the excessive pressure acting from each treatment child can be suppressed.

In the massage unit 50 according to the present embodiment, the left and right support plates 520 are configured to be in the same position. That is, the treatment is performed when the left and right support plates 520 are both in the first position P1 or both in the second position P2. However, it is not limited to this. For example, one of the left and right support plates 520 may be in the first position P1 and the other may be in the second position P2. Further, when one of the left and right support plates 520 is in the first position P1, the other may be located between the first position P1 and the second position P2. Further, when one of the left and right support plates 520 is in the second position P2, the other may be located between the first position P1 and the second position P2.

In the massage unit 50 of the present embodiment, in the second position P2, the support plate 520 is rotated so that the upper arm portion 523 projects forward, and the upper treatment child 521 comes into contact with the body of the treated person. It is a one-point support position. However, the present invention is not limited to this, and the support plate 520 may be rotated so that the lower arm portion 524 projects forward, and the state in which the lower arm portion 522 is in contact with the body of the patient may be set as the second position.

<First modification>
FIG. 8 is an enlarged side view of the support plate 520 of the treatment unit 52A of the massage unit of the first modification. The treatment unit 52A of the massage unit 50 shown in FIG. 8 is different from the treatment unit 52 in that it has the lower treatment element 522A instead of the lower treatment element 522. The treatment unit 52A has the same configuration as the treatment unit 52 except that the lower treatment element 522A is different. Therefore, substantially the same parts as the treatment part 52 of the treatment part 52A are designated by the same reference numerals, and detailed description of the same parts will be omitted.

As shown in FIG. 8, the maximum outer diameter of the upper treatment child 521 is larger than the maximum outer diameter of the lower treatment child 522A. The maximum outer diameter of the treatment element is the largest of the diameters centered on the rotation axis of the outer peripheral surface centering on the rotation axis of the treatment element.

By forming the maximum outer diameter of the lower treatment child 522A smaller than the maximum outer diameter of the upper treatment child 521, it is difficult for the support plate 520 to come into contact with the lower treatment child 522A when it moves to the second position P2. .. Therefore, when it is desired to perform treatment with a strong pressure, the pressure is difficult to disperse and the treatment effect can be enhanced. Further, in this modification, the lower treatment child 522 is replaced with the lower treatment child 522A having a smaller maximum outer diameter, but the present invention is not limited to this. The lower treatment child 522 may be left as it is, and the upper treatment child 521 may be replaced with one having a large maximum outer diameter.

<Second modification>
FIG. 9 is a side view of the treatment unit 52B when the support plate 520 of the massage unit 50 of the second modification is at the first position P1. FIG. 10 is a side view of the treatment unit 52B when the support plate 520 of the massage unit 50 of the second modification is at the second position P2. The treatment unit 52B shown in FIGS. 9 and 10 is different from the rotation actuating unit 56. Other points of the treatment unit 52B have the same configuration as the treatment unit 52, the same parts are designated by the same reference numerals, and detailed description of the same parts will be omitted.

As shown in FIGS. 9 and 10, the rotation actuating portion 56 of the treatment portion 52B can urge the support plate 520 in both directions around the rotation axis Ax, and the first position P1 and the second position. It has an actuator capable of holding the support plate 520 at P2. More specifically, the rotation actuating portion 56 has an actuator including a ball screw 561, a ball nut 562, and a drive portion 563.

The ball nut 562 has a ball that is externally fitted to the ball screw 561 and rolls in a spiral groove formed on the outer peripheral surface of the ball screw 561. The ball nut 562 is rotatably attached to the support plate 520. The drive unit 563 has a power source for rotating the ball screw 561. Examples of the power source include, but are not limited to, an electric motor. The drive unit 563 is rotatably supported by the base member 51.

In the rotation operating portion 56, the ball screw 561 rotates, so that the ball nut 562 moves along the ball screw 561. As the ball nut 562 moves, the support plate 520 rotates toward the first position P1 or toward the second position P2.

When the rotation actuating portion 56 is used, the function of the ball screw 561 and the ball nut 562 allows the support plate 520 at the second position P2 to be on the first position P1 side even when a force from the patient is applied to the support plate 520. It is difficult to move. Even if a force is applied to the upper treatment child 521 by the treatment recipient, the body Bd (for example, shape, weight, etc.) of the treatment recipient is measured in advance in order to suppress the action of a certain pressure or more, and the measurement thereof. The second position P2 may be adjusted based on the result. Further, the drive unit 563 may be driven so as to move the ball nut 562 to the first position P1 side when a load of a certain level or more acts on the upper treatment child 521 from the body Bd of the person to be treated. ..

By having the pair of treatment units 52 having such a configuration, the massage unit 50 can suppress the application of pressure above a certain level to the body Bd of the treated person, and can suppress the discomfort of the treated person.

Although the embodiments and modifications of the present invention have been described above, the configurations and combinations thereof in the embodiments are examples, and the configurations are added, omitted, replaced, and the like without departing from the spirit of the present invention.
