(First embodiment)
A first embodiment of the present invention will be described below with reference to the drawings.
FIG. 1 shows a schematic configuration of the massage machine of the present embodiment. As shown in FIGS. 1 and 3 (a) and 3 (b), the massage machine 10 has a total of four support portions 12 and 13 disposed on a base portion 11 that is a floor surface (not shown), and the support portions. 12 and 13 support a seat 14 on which a user can sit. A tilting mechanism 17 (see FIG. 4) is provided on the back side of the seat portion 14 with a backrest portion 15 for allowing the user to lean back and an ottoman 16 on which the user's legs can be placed on the front side of the seat portion 14. ) To be tiltable. An armrest 18 for placing the user's arm is provided from the backrest 15 to the front of both sides of the seat 14.

  As described above, the seat portion 14 is supported by a total of four support portions 12 and 13 (only two are shown in the figure) provided on the left and right side surfaces of the front and rear portions. The support portion 12 on the front side is long in one direction (vertical direction), the base end side is fixed to the base portion 11, the support member 12 a is disposed on the distal end side of the support member 12 a, and the seat portion 14 And a fixed portion 12b to be connected. The seat portion 14 is configured to be rotatable about the fixed portion 12b.

  On the other hand, the support portion 13 on the rear side is formed along a vertical direction of the support member 13a and a support member 13a which is long in one direction (vertical direction) like the support member 12a and whose base end side is fixed to the base portion 11. And a movable portion 13c provided movably in the guide groove 13b. The movable portion 13c constitutes posture changing means for changing the posture of the user. The movable portion 13c is connected to the seat portion 14 and is moved along the guide groove 13b by the movable portion drive source 19 (see FIG. 4). It can be moved in the vertical direction. The movable part drive source 19 is electrically connected to a control unit 20 (see FIG. 4), and the drive of the drive source 19 is appropriately controlled by the control unit 20. For this reason, the seat portion 14 connected to the movable portion 13c is moved up and down on the rear side of the seat portion 14 by moving the movable portion 13c, and the backrest portion 15 connected to the rear portion of the seat portion 14 is moved. The front side will be moved up and down. Thus, the posture of the user can be changed by moving the rear side of the seat 14 and the front side of the backrest 15 up and down. Further, at this time, the tilting mechanism 17 is controlled by the control unit 20 for the backrest 15 so that the angle formed by the backrest 15 and the seat 14 is adjusted as appropriate. In the present embodiment, the movable portion 13c and the tilt mechanism 17 constitute posture changing means.

  As shown in FIG. 2, the ottoman 16 provided at the front portion of the seat portion 14 has a concave leg support portion on which a user's leg portion (lower leg) can be inserted on the connecting base portion 16 a extending in the left-right direction. A total of two 16b are arranged on the left and right. The ottoman 16 is configured such that each leg support portion 16b can be swung in the left-right direction by a swing driving portion 21.

  As shown in FIG. 2, the swing drive unit 21 converts a motor 22 whose drive is controlled by the control unit 20 and a rotational driving force of the motor 22 into a moving force (linear motion) in the left-right direction. And a linear motion conversion mechanism 23.

  The linear motion conversion mechanism 23 includes a guide rail 24 that allows the connection base portion 16a to move in the left-right direction, and a link member 25 that is connected to a part of the connection base portion 16a. The link member 25 is connected at one end to a rotating member 22a provided at the tip of a rotating shaft (not shown) of the motor 22. For this reason, the base end side of the link member 25 is rotated by rotating the rotating shaft of the motor 22, and the distal end side of the connecting base portion 16a is moved along the guide rail 24 by the rotational driving force in the left-right direction. It is designed to move. In this way, the connecting base portion 16a is moved in the left-right direction along the guide rail 24, whereby the leg support portion 16b of the ottoman 16 is integrally swung.

  By the way, in a so-called sports massage scene, only the legs are effectively swung while the waist is relatively lowered by lifting the ankle. At this time, the swinging speed should be relatively high. Furthermore, in order to limit the swinging part, an arrangement is made such that the body is laid sideways or only one leg is raised and shaken. On the other hand, in the so-called goldfish exercise, swinging is transmitted to the whole body by creating a posture in which the whole body is extended and both legs are closed. At this time, the swinging speed can be transmitted to the whole body by performing the swinging operation at a relatively slow speed.

  As described above, in order to change the swinging effect part, it is necessary to appropriately define the posture of the user. Further, it is desirable that the swing regulates the operation in cooperation with the user's posture. Such a regulation of the posture is difficult to achieve only by reclining for tilting the upper body and adjusting the angle of the ottoman who stretches the knee. Further, there is a problem that the user does not know a suitable posture for changing the effect site by the swing.

  Therefore, in the massage machine 10 configured as described above, the control unit 20 controls the swinging drive unit 21 and the movable unit 13c and the tilting mechanism 17 constituting the posture changing means to perform a cooperative operation. Here, the “cooperative operation” is to operate the seat 14 and the backrest 15 so as to change (change) the posture of the user in accordance with the purpose of the swing operation by the swing drive unit 21.

  For example, when the ottoman 16 is swung in the left-right direction by the rocking drive unit 21, the control unit 20 drives the movable unit when it is desired to perform a rocking motion around the user's leg (lower body). The source 19 is controlled to move the movable portion 13c downward. At this time, the control unit 20 controls the tilting mechanism 17 to erect the backrest 15 until the angle formed by the seat 14 and the backrest 15 is approximately 90 degrees. This makes it possible to increase the load on the waist by bending the angle of the user's waist (hip joint) to approximately 90 degrees. For this reason, by swinging the ottoman 16, the swing is transmitted only to the user's waist, and a swing operation centering on the lower body can be realized.

  Further, when the ottoman 16 is swung in the left-right direction by the swing driving unit 21, when the user wants to swing the entire body of the user, the control unit 20 controls the movable unit drive source 19 to move. The seat portion 14 is made substantially parallel to the floor surface by moving the portion 13c upward. At this time, the control unit 20 controls the tilting mechanism 17 to tilt the backrest 15 to an angle (for example, approximately 150 degrees) such that the angle formed by the seat 14 and the backrest 15 approaches 180 degrees. Thus, by increasing the angle formed by the seat portion 14 and the backrest portion 15, it is possible to make the user sleep. Therefore, by swinging the ottoman 16, the swing is transmitted to the upper body of the user so that the swing motion of the entire body of the user can be realized.

  As described above, the posture of the user is controlled by the control unit 20 so that the tilting mechanism 17 and the movable unit 13c are controlled so as to perform a cooperative operation according to the purpose of the swing, such as swinging around the lower body or swinging the whole body. Thus, the body part to which the massage effect is imparted can be suitably changed.

Next, characteristic effects of the present embodiment will be described.
(1) The massage machine 10 includes a movable portion 13c and a tilting mechanism 17 as posture changing means that can change the posture of the user when swinging. The movable unit 13c and the tilting mechanism 17 are controlled by the control unit 20 in such a manner that the movable unit 13c and the tilting mechanism 17 operate cooperatively according to the purpose of swinging. By adopting such a configuration, it is possible to suitably change the body part to which the massage effect by the rocking motion is given according to the purpose of the rocking motion. (2) The seat portion 14 on which the user can be seated, A backrest portion 15 provided at the rear portion of the seat portion 14 is provided. The movable portion 13c and the tilting mechanism 17 constituting the posture changing means tilt both the seat portion 14 and the backrest portion 15 to change the angle formed by the portions 14 and 15, so that the user's swinging motion can be achieved. The posture is changed. In this way, by changing the angle formed by the backrest 15 and the seat 14, the angle of the user's hip joint is changed, and the user's whole body can be swung around the user's leg. It can be suitably swung.

(Second Embodiment)
Hereinafter, a second embodiment of the present invention will be described with reference to FIG. In addition, about the same member as 1st Embodiment, the same code | symbol is attached | subjected and all or one part of drawing and description is omitted.

The ottoman 40 provided in the massage machine of the present embodiment is provided on each of the two sides (two sides) on the lower side of the substantially triangular base member 41 arranged on the front side (the front side of the paper) of the seat portion 14. A connecting member 42 connected to the fixing portion 16c provided at the upper end of each of the 40 leg support portions 16b is provided. The connecting member 42 is formed of a member whose length can be adjusted, such as a turnbuckle. For this reason, for example, the ottoman 40 can be tilted in the left-right direction with respect to the seat portion 14 by adjusting the length of each connection member 42 with a drive source (not shown).

  Here, for example, when the ottoman 40 is in a normal state in which it is not tilted as shown in FIG. 5 (a), the ottoman 40 is either in the left-right direction as shown in FIG. 5 (b). The difference from the swinging operation when the tilted state is tilted to the right will be described.

  As shown in FIG. 5A, when the ottoman 40 is parallel (non-tilt) with respect to the seat portion 14, the position of the center of gravity of the user is set to the approximate center position in the left-right direction of the seat portion 14. For this reason, by swinging the ottoman 40 to the left and right by the swing drive unit 21 (see FIG. 2), the user's legs and body can be swung in a well-balanced manner.

  On the other hand, as shown in FIG. 5B, when the ottoman 40 is tilted to the right in the left-right direction with respect to the seat portion 14, the user's waist can be twisted. More specifically, the right connection member 42 is changed by a drive source (not shown) so that the length of the right connection member 42 is longer and the length of the left connection member 42 is shorter, so that both knees of the user can be The posture is changed so that the toe is to the right with respect to the center and the toes are to the left with respect to the center of the body. As a result, the center of gravity of the user is shifted to the right side, and the left body can be easily swung. Further, by shortening the length of the right connection member 42 and increasing the length of the left connection member 42, the center of gravity of the user can be shifted to the left side, and the right body is swung. It becomes easy.

  As described above, the posture of the user is changed by switching between the tilted state in which the ottoman 40 is tilted in the left-right direction with respect to the seat portion 14 and the non-tilted state in accordance with the purpose of the swinging operation. The body part to which the massage effect is imparted can be suitably changed.

Next, characteristic effects of the present embodiment will be described.
(1) The leg support portion 16b constituting the ottoman 16 is provided at the front portion of the seat portion 14 on which the user can be seated, and each leg portion (lower leg) of the user can be tilted integrally in the left-right direction. Configured. And it is comprised so that the attitude | position at the time of a user's rocking | fluctuation may be changed by inclining in the left-right direction with respect to the seat part 14 of the support part 16b for legs. Thus, by tilting the leg support portion 16b integrally with the seat portion 14, the swing center of the user can be shifted left and right. Further, when the leg support 16b is not tilted, the position of the center of gravity of the user is set to the substantially center position in the left-right direction, and the user's legs and body can be vibrated with good balance.
