And so on. In the present embodiment, the path when the body support member 13 moves from the rear to the front is defined as the forward path, and the path when the body support member 13 is moved from the front to the rear is defined as the return path.

  A seat portion 30 constituting the chair-type body support member 13 is fixed to the upper portion of the base portion 25 so as to be movable together with the base portion 25. A backrest part 31 fixed to the rear part of the seat part 30 so as to be tiltable, an ottoman 32 fixed to the front part of the seat part 30, and an armrest part 33 fixed to both the left and right sides of the seat part 30 are provided. Yes.

  As shown in FIG. 2, the reclining mechanism 34 that tilts the backrest 31 is controlled by the controller 24, and the backrest 31 is tilted appropriately.

  A pair of left and right airbags 40 and 41 are provided on the backrest 31 on both sides of the upper stage so as to correspond to the left and right shoulders of the user.

Also, instead of providing a force sensor, a force control value profile is created from weight load data that changes in accordance with a pre-measured swing cycle, and the user controls the force by inputting the weight. May be performed. Moreover, the force control part 2 determines the force of pressing operation | movement, and the pushing amount of pressing operation by a massage means according to the force detected by this force sensor.

  Next, the force of the swinging operation and pressing operation of the swinging device 10 configured as described above will be described with reference to FIGS. Note that in (b) to (j) of FIG. 3, the waveform with a fine period indicates each pressing operation by the inflating / contracting operation of the airbags 40 to 48. The waveform of the envelope by the locus of the force of each pressing operation (the force applied to the point A in FIG. 3) applied to the back of the user will be described below as the waveform of the pressing operation force.

  The waveform shown in (a) of FIG. 3 shows the swinging motion of the swinging device 10 and shows the time change of the position of the body support member 13.

  The waveform of each pressing operation and the waveform of the force of the pressing operation shown in FIG. 3B show a conventional example, and show that the swing device 10 does not have the force control unit 2.

  In the waveform shown in FIG. 3C, the force control unit 2 performs control to reduce the force of the pressing operation given to the user as a whole. Note that not only the force of the pressing operation is decreased, but control with an arbitrary force such as increasing the force may be performed.

  In the waveform shown in FIG. 3 (d), the force control unit 2 synchronizes with a period T that is twice the period in the swinging operation, and the force of the pressing operation given to the user is controlled with an arbitrary force. Yes. Note that the oscillating motion is not limited to a double cycle, but may be any integer multiple such as triple.

  In the waveform shown in (e) of FIG. 3, the force control unit 2 performs control to decrease and then increase the force of the pressing operation during one cycle of the cycle of the swinging operation. At this time, the force of the pressing operation applied to the user is controlled to gradually increase as a whole. Further, the control is performed so that the acceleration to be increased is larger than the acceleration to decrease the force of the pressing operation.

  In the waveform shown in FIG. 3 (f), the force control unit 2 decreases and then increases the force of the pressing operation during one cycle of the swinging operation, similarly to the waveform shown in FIG. 3 (e).

  In the waveform shown in (h) of FIG. 3, the force control unit 2 keeps the force of the pressing operation given to the user constant for one cycle of the cycle in the swing operation, as in the waveform shown in (g) of FIG. 3. Keep on. And the force control part 2 performs control which reduces force in steps at the time of a change from a return path to an outward path.

In the waveform shown in (i) of FIG. 3, the force control unit 2 performs control to decrease the force of the pressing operation given to the user step by step for each period T. Note that the period T is not limited to one period in the swinging operation, but may be a period T that is a natural number multiple such as double or triple.

  In the waveform shown in (j) of FIG. 3, the force control unit 2 performs control to increase stepwise the force of the pressing operation given to the user for each period T. Note that the period T is not limited to the period in the oscillating operation, but may be a period T that is a natural number such as double or triple.

  Note that the force control shown in (c) to (j) of FIG. 3 can be switched according to the preference of the user.

  Therefore, in the oscillating device 10 of the present embodiment, the massage means includes the force control unit 2 that controls the pressing operation, and the force control unit 2 has a period T (n = 1) of the pressing operation n times that of the oscillating operation. , 2, 3... Accordingly, since the pressing operation according to the cycle of the swinging operation can be performed, it becomes easier for the user to feel further fatigue reduction.

  Further, in the swing device 10 of the present embodiment, the force control unit 2 can sequentially perform control to increase and decrease the force of the pressing operation when the swing operation changes in the reciprocating direction. Thus, it becomes easier for the user to feel an increase or decrease in the force of the pressing operation within a limited increase / decrease range of the force.

  Further, in the swing device 10 of the present embodiment, the force control unit 2 can perform control to make the force of the pressing operation constant for each period T. By the pressing operation according to the period T, massage can be performed with a constant force regardless of the swinging operation, so that the user can easily obtain both the effects of the swinging operation and the pressing operation.

  Moreover, in the rocking device 10 of this embodiment, the force control part 2 can perform control which increases the force of pressing operation in steps for every period T. This makes it easier for the user to obtain a refreshing feeling that leads to an awakened state.

  Further, in the swinging device 10 of the present embodiment, the force control unit 2 can perform control to decrease the force of the pressing operation step by step for each period T. This makes it easier for the user to get a sense of relaxation that leads to the sleep state.

  Moreover, in the rocking | swiveling apparatus 10 of this embodiment, a massage means is provided with the position control part 3 which changes the position which performs a massage. Thereby, since the force control part 2 controls the force of a press operation according to a user's body shape line, the force of a predetermined press operation can be given to a predetermined position.

  Moreover, in (c) to (j) of FIG. 3, the force control unit 2 may be controlled to be performed several times with the four periods of the swinging operation as one term, but arbitrary waveforms are combined one by one. Control may be performed. One term is not limited to the four cycles of the swinging operation, but may be one cycle, two cycles, or the like.

  In the present embodiment, the waveform with a fine period indicates each pressing operation by the inflating / contracting operation of the airbags 40 to 48. The waveform of the envelope by the locus of the force of each pressing operation is the waveform of the force of the pressing operation. However, massage that keeps pressing may be performed so that the inflation / deflation operation of the airbag follows the waveform of the envelope.

  Although not particularly mentioned in the above embodiment, the oscillating device 10 includes a pulse sensor that is attached to the user and detects a pulse, and the pulse rate is reduced based on information obtained from the pulse sensor. Accordingly, control for gradually weakening the force of the pressing operation may be performed.

  Moreover, in this embodiment, although the airbag 40 thru | or 48 is used for the massage means, as shown in FIG. 4, you may use the fir ball 50 instead of an airbag. In this case, the force control unit 2 controls the pressing force of the fir ball 50 and the pushing amount of the pressing operation, and the position control unit 3 adjusts the fir ball along the rail 51 provided on the back side of the backrest 31. Control to move 50 up and down.
