The seats 22 are tilted in the left-right direction of the main body 1 by raising and lowering the corresponding arms 29 by the corresponding tilting motors 28 (see FIG. 11A).
On the other hand, in addition to using the rotation motor 27 and the tilting motors 28 and 28, the seat portion can be rotated and / or tilted by a parallel mechanism.

  FIG. 10 is a schematic perspective view showing a main configuration of a massage machine having a parallel mechanism. For example, the parallel mechanism 40 faces a substantially hexagonal base member 41 obtained by cutting each apex portion of a triangle, and a support member 42 that has the same shape as the base member 41 and supports the seat portion 2 is formed with the base member 41. It is arranged by rotating approximately 90 degrees in a parallel plane, and cylinder type actuators 43, 43,... Are respectively constructed between each vertex of the base member 41 and each vertex of the support member 42. .. By driving the required actuators 43, 43,... Forward and backward, as shown in FIGS. It can be rotated around and / or tilted in the front-rear direction and the left-right direction of the massage machine.

  In the massage machine that drives these seats 2, when performing the various stretches described above, the seat 2 is rotated around a central axis that vertically penetrates the center of the seat 2, and / or Alternatively, by tilting in the front-rear direction and the left-right direction, the user can be twisted and / or stretched, and the stretch effect can be improved.

For example, when the user holds the first stretch bar 71 and tilts the backrest part 3 (both see FIG. 1) to perform the stretching, the seat part 2 is moved backward toward the backrest part 3 side. By tilting, the user's buttocks can be separated from the first stretch bar 71, and the stretch effect is improved.
In addition, when the user is performing the same stretch as before using the first stretch bar 71, a twist stretch is added to the user by rotating the seat 2 forward and backward. Can be applied.

  On the other hand, when the user holds one of the second stretch bars 72 (see FIG. 5) and tilts the backrest portion 3 to perform the stretch, the seat portion 2 is moved to the second stretch bar. By tilting to the opposite side to 72, the portion of the buttocks of the user opposite to the second stretch bar 72 can be separated from the second stretch bar 72, and the stretch effect is improved.

  In addition, when the same stretch as before is performed using one of the second stretch bars 72, the seat 2 is rotated from the second stretch bar 72 toward the front of the massage machine. Therefore, the stretch effect of the twist can be improved.

  Further, when the user holds the third stretch bars 73 and 73 (see FIG. 5) and tilts the backrest portion 3 to perform stretching, the seat portion 2 is opposite to the backrest portion 3. By tilting forward to the side, the user's buttocks can be separated from the third stretch bars 73, 73, and the stretch effect is improved.

In addition, when the same stretch as before is performed using the third stretch bars 73, 73, the seat portion 2 is rotated forward and backward to add a twist stretch to the user. Can do.
Further, when the instep of the user is engaged with the fourth stretch bars 74, 74 (see FIG. 5) and one or both footrest portions 5, 5 are tilted, the stretch is performed. By tilting the seat 2 toward the back of the main body 1, the thigh of the user can be separated from the fourth stretch bars 74, 74, and the stretch effect is improved.
On the other hand, when the same stretch as before is carried out, a twist stretch can be additionally applied to the user by rotating the seat 2 forward and backward.

(Fourth embodiment of the present invention)
FIG. 12: is a side view which shows typically the principal part structural example of the massage machine which concerns on the 4th Embodiment of this invention, and the backrest part 3 is comprised so that tilting and rotation are possible. In the figure, parts corresponding to those shown in FIG.
As shown in FIG. 12, a box-shaped frame member 30 having an outer dimension slightly larger than the backrest 3 is erected on the back side of the backrest 3 at an appropriate inclination angle. For example, the above-described parallel mechanism is installed inside the frame member 30, and the backrest 3 is supported by the parallel mechanism so as to be rotatable and tiltable.

That is, as shown in FIG. 13B, the backrest 3 is rotated around the central axis that vertically penetrates the backrest 3. Moreover, the backrest part 3 can be tilted also to the front-back direction and the left-right direction of a massage machine, as shown to Fig.13 (a).
Thereby, a twist and / or elongation can be given to the user, and the stretch effect can be improved as before.

  In the present embodiment, the backrest 3 is supported by, for example, a parallel mechanism and can be rotated around the central axis passing through the backrest 3 vertically and / or tilted in the front-rear direction and the left-right direction of the main body 1. However, the present invention is not limited to this, and may be configured to be able to rotate around the central axis that vertically penetrates the backrest 3 and / or tilt in the front-rear direction of the main body 1. For example, the backrest portion 3 shown in FIG. 1 is surrounded by an annular frame, and both ends of a rotation shaft that vertically penetrates the backrest portion 3 are rotatably supported by the frame. The drive part which rotates is attached to the frame. Note that one end of the first driving unit 11 shown in FIG. 1 is connected to the frame instead of the backrest unit 3.

  Incidentally, a massage machine including both a mechanism for driving the backrest 3 and a mechanism for driving the seat 2 as described above can also be used as an embodiment of the present invention. Thereby, for example, the backrest part 3 and the seat part 2 can be rotated in opposite directions, and the twisting effect can be improved. Further, by combining the rotation of the backrest 3 and the tilting of the seat 2, the twisting effect due to the rotation of the backrest 3 can be adjusted by the tilting of the seat 2.

(Another embodiment of the present invention)
FIG. 14 is an external perspective view showing a massage machine according to another embodiment, in which a seated user is clamped by an air cell. In the figure, parts corresponding to those shown in FIG. 1 are denoted by the same reference numerals and description thereof is omitted.
As shown in FIG. 14, in both armrests 4 and 4 of the massage machine, the side cell air cells i and i that are pressed against the side of the user wearing the seat 2 and the user When the side thigh air cells j, j that are in pressure contact with the side thighs are installed and the side buttocks air cells i, i and the side thigh air cells j, j are inflated, the side of the user The hip and side thighs are sandwiched.

  Further, by inflating the body side upper air cells c, c of the both side walls 31, 31 described above, a portion extending from the shoulder side portion of the user wearing the seat portion 2 to the upper arm portion is sandwiched, and both footrest portions The leg inner air cells g, g and the leg outer air cells h, h are inflated to sandwich the legs of the user fitted into the footrest parts 5, 5 respectively. It has become.

Then, the subject is stretched as follows.
FIG. 15 is an example of a control timing chart for applying stretching to a user. When a drive start stop signal is input in the drive stop state, for example, the side thigh air cell, the side heel air cell, the body side inner air cell, and the body side outer air cell are supplied and expanded in this order, The relevant part of the user wearing the seat is clamped from the lower part to the upper part. During this time, other air cells such as the back air cell are not expanded.

  Then, the backrest is tilted and / or rotated in a state where the upper body and the lower body of the user are separately held by the corresponding air cells. When a driving start / stop signal is input in the driving state, each side thigh air cell, side heel air cell, body side inner air cell and body side outer air cell are exhausted and the backrest portion is returned to the original posture. Let

  When the backrest is tilted, the upper body of the user tries to slide down on the backrest so that it is relatively in the lower position, but the part from the shoulder side of the user to the upper arm is for the body side. Since it is sandwiched between the inner air cell and the outer air cell for the body side, the above-mentioned sliding is inhibited, while the lower body of the user is sandwiched between the side thigh air cell and the side heel air cell, The tilting also inhibits the lower body from floating from the seat, and this allows stretching mainly on the waist and back of the user.

Moreover, when the backrest part is rotated, a twist stretch can be applied to the user in a posture in which the upper and lower bodies of the user are stably held.
In this control timing chart, the tilting of the backrest portion is started after the corresponding air cell is inflated, but the present invention is not limited to this, and the backrest portion of the backrest portion is appropriately timed before the expansion of the air cell is completed. Tilt may be started.

  On the other hand, the case where the upper half and the lower half of the user are sandwiched between the corresponding air cells has been described, but the upper half or the lower half of the user may be sandwiched.

  For example, the body side inner air cell and the body side outer air cell are inflated to sandwich a portion extending from the shoulder side portion of the user to the upper arm portion, while the side collar portion and the side thigh portion of the user are opened. Then, as described above, the seat is rotated and / or tilted back and forth, left and right, so that the posture of the user's upper body is stably held, and the waist and back of the user are twisted and extended. Can be stretched.

Further, both the footrest portions are raised and the side thigh and / or the side collar of the user are sandwiched between the side thigh air cell and / or the side collar air cell, and the leg inner air cell and leg The leg portions of the user can be stretched by sandwiching both leg portions with the outer air cell for the part and lowering both footrest portions simultaneously or alternately in this state. At this time, since the side thigh and / or the side buttock of the user are sandwiched, the position of the buttock of the user on the seat is prevented from shifting, and the stretch is more effective with respect to the leg. Can be given.
The stretch using the air cell described above can also be applied to each embodiment using the above-described stretch bar, and the stretch using the stretch bar and the stretch using the air cell can be performed simultaneously.
