(First embodiment)
Hereinafter, a first embodiment in which the present invention is embodied in a chair-type massage machine will be described with reference to FIGS.

  As shown in FIG. 1, a chair-type massage machine 10 as a swing device includes a leg portion 11 placed on a floor surface (not shown), and a seat on which a user can sit above the leg portion 11. The part 12 is fixed. On the rear side of the seat portion 12, a backrest portion 13 is provided so that the user can tilt the backrest so that the user can lean on the back. Further, an ottoman 15 (a leg mount) on which a user's legs can be placed is provided on the front side of the seat portion 12 so as to be tiltable. Further, on both the left and right sides of the seat portion 12, armrest portions 16 for placing the user's arms are provided from the backrest portion 13 to the front sides of the seat portion 12. The ottoman 15 is provided with a total of two leg support portions 18 each having a concave shape into which a user's leg can be inserted. Each leg support portion 18 can swing in the left-right direction. Moreover, the backrest part 13 and the seat part 12 are each provided with a back pressing part 20a, a waist pressing part 20b, and a seat pressing part 20c made of an airbag capable of pressing a part of the user's body. Further, the backrest 13 is internally provided with a treatment element (not shown) such as a fir tree for performing body massage. In the present embodiment, the leg support 18 corresponds to a support unit and a leg support unit.

  As shown in FIG. 2, the pair of left and right leg support portions 18 can swing integrally in the left-right direction with respect to the connecting base portion 24 swingable in the left-right direction, and can move in the longitudinal direction of the leg K ( It is mounted in a state that can be raised and lowered. By raising and lowering the leg support portion 18, it is possible to support an arbitrary part within the range from the ankle of the user's leg K to below the knee. Here, in the ottoman 15, the rise of the leg support 18 indicates movement toward the knee side, and the descent thereof indicates movement toward the toe side. The ottoman 15 swings as a swinging portion changing means that changes the swinging portion of the body when the leg support portion 18 swings in the left-right direction by moving the leg support portion 18 in the longitudinal direction of the leg. A site changing mechanism 23 is provided.

  As shown in FIG. 3, the connecting base portion 24 with the left and right leg support portions 18 attached to the front surface (lower side in FIG. 3) is a swing drive means disposed on the rear side (upper side in FIG. 3). When the oscillating drive unit 19 is driven, the oscillating motion in the left-right direction is performed. Swing drive unit 19 includes a motor 25 serving as a power source, and a linear motion conversion mechanism 26 for converting the rotational driving force of the motor 25 into reciprocating linear motion in the lateral direction.

  The linear motion conversion mechanism 26 includes a guide rail 27 installed on a fixed frame (not shown) of the ottoman 15 so as to extend in the left-right direction, and a pair supported slidably along the guide rail 27. And a connecting base portion 24 having a movable portion 24a. Further, the linear motion conversion mechanism 26 is provided between a rotating member 25a that is coaxially connected to a rotating shaft (not shown) of the motor 25, and the rotating member 25a and one (right side in FIG. 3) movable portion 24a.

The link member 28 has a base end portion rotatably connected to the peripheral portion of the rotating member 25a, and a tip end portion rotatably connected to one (right side in FIG. 3) movable portion 24a. Yes.

  For this reason, when the motor 25 is driven to rotate the rotating member 25a and the base end portion of the link member 28 rotates, a force is transmitted to one of the movable portions 24a connected to the distal end portion thereof. As the movable portion 24 a reciprocates in the left-right direction along the guide rail 27, the connection base portion 24 reciprocates in the left-right direction along the guide rail 27. As described above, the connecting base portion 24 reciprocates in the left-right direction along the guide rail 27, whereby the leg support portion 18 of the ottoman 15 swings integrally.

  As shown in FIG. 4D, the ottoman 15 moves the leg support portion 18 up and down to change the support position (support portion) of the leg K supported by the leg support portion 18, thereby A swinging part changing mechanism 23 for changing the swinging part to be swung is provided. The swinging part changing mechanism 23 includes a leg support 18 and a direct acting actuator 29. The direct-acting actuator 29 is assembled on the back surface of the connection base portion 24, and the leg support portion 18 is fixed to the tip end portion of the drive shaft 29a. 2 and 3 is formed with a slit (not shown) extending in the longitudinal direction (longitudinal direction of the leg), and the leg support 18 is provided on the back surface of the coupling base 24 via the slit. It is connected to the drive shaft 29a (see FIG. 4D) on the side. The actuator 29 shown in FIG. 4D is, for example, a direct-acting electric actuator, and the leg support portion 18 is moved from the position shown in FIGS. As shown in (c), it slides in the ascending / descending direction (vertical direction in FIG. 4).

  The leg support 18 has a lowering range / intermediate whose center height is the lowered position shown in FIG. 4A, the intermediate position shown in FIG. 4B, and the raised position shown in FIG. 4C. It moves up and down so as to belong to any one of the range and the ascending range. When the leg support 18 swings in the left-right direction (in the direction of the arrow in the figure) in the state where it is in the lowered position shown in FIG. 4 (a), a swinging force is applied to the tip side of the leg K, The foot becomes the swinging part. Further, when the leg support portion 18 swings in the left-right direction with the intermediate position shown in FIG. 4 (b), a swinging force is applied to the intermediate part of the lower leg of the leg K, and the entire lower leg and the foot are It becomes a rocking part. Further, when the leg support 18 swings in the left-right direction with the leg support 18 in the raised position shown in FIG. 4C, a swinging force is applied to the lower part of the leg K, and the entire leg becomes the swinging part. .

  Next, an electrical configuration related to swing control in the massage machine 10 will be described. As shown in FIG. 5, the massage machine 10 is provided with a main control unit 30 that performs various controls including swing control of the ottoman 15. The main control unit 30 includes a first control unit 31 for driving and controlling the swinging part changing mechanism 23, and a swinging control unit for driving the swinging drive unit 19 to swing the leg support unit 18 and controlling the swinging frequency thereof. The dynamic frequency control unit 32 is electrically connected. The main control unit 30 is operated by the user when starting / stopping the operation of the massage machine 10, performing a reclining operation, inflating and contracting the airbag, swinging movement of the ottoman 15, raising and lowering the leg support unit 18, and the like. A remote control type operation unit 34 is connected. When the user operates the operation unit 34 to instruct raising / lowering of the leg support unit 18, the first control unit 31 drives and controls the actuator 29 in accordance with an instruction from the main control unit 30, and the user operates the operation unit 34. The leg support 18 is moved in the direction indicated by. In addition, the main control unit 30 also performs drive control of a treatment element such as a fir tree incorporated in the backrest unit 13 of the massage machine 10.

  The 1st control part 31 changes the rocking | swiveling part of a body by changing the position of the raising / lowering direction of the leg support part 18. FIG. Specifically, when each leg support 18 having both legs K inserted in a state where the user is seated on the massage machine 10 oscillates in the left-right direction, the foot is lifted from the swing fulcrum determined according to the lift position of the leg support 18. The previous part becomes the swinging part (swinging region).

  The swinging part changing mechanism 23 is provided with a sensor 35 for detecting the support position of the leg K by the leg support 18. As the sensor 35, for example, a position sensor that detects the elevation position of the leg support portion 18 is used. The first control unit 31 acquires the lift position of the leg support unit 18 based on the detection result input from the sensor 35.

  The swing frequency control unit 32 refers to the correspondence between the lift position of the leg support 18 (that is, the support position of the leg K) and the swing frequency, that is, the correspondence between the swing portion of the leg K and the swing frequency. Data is stored in memory. The swing frequency control unit 32 sequentially acquires the lift position information of the leg support unit 18 from the first control unit 31 via the main control unit 30 when the swing drive unit 19 starts driving and during driving, and stores it in the memory. By referring to the stored reference data, the swing frequency corresponding to the acquired lift position of the leg support 18 is acquired. Then, the swing frequency control unit 32 controls the motor 25 at a rotational speed at which the leg support unit 18 can be swung at the acquired swing frequency. In detail, the reference data stores data such as the rotation speed of the motor 25 corresponding to the lift position of the leg support 18 or a voltage value (for example, duty value) that determines the rotation speed. It is good also as a structure which controls the rotational speed of the motor 25 based on the rotational speed or voltage value acquired with reference to reference data based on the 18 raising / lowering positions.

  Further, the swing drive unit 19 is provided with a sensor 36 including a rotary encoder that can directly or indirectly detect the rotation of the motor 25. The swing frequency control unit 32 acquires the rotational speed of the motor 25 based on the detection signal input from the sensor 36, and the actual swing when the leg support unit 18 swings in the left-right direction based on the rotational speed. The frequency F is acquired. Then, the oscillation frequency control unit 32 performs feedback control so as to bring the actual oscillation frequency closer to the oscillation frequency commanded from the main control unit 30. Of course, feedforward control of the oscillation frequency F may be adopted.

  In the reference data of the present embodiment, different oscillation frequencies are set for each elevation position of the leg support 18. For example, as shown in FIG. 6, different swing frequencies F2, F3, and F1 (where F1 <F2 <F3) are set for each of the swing portions A, B, and C determined according to the lift position of the leg support 18. Has been. FIG. 6 is an example, and the swing frequency corresponding to the swinging portions A, B, and C may be different for each of the swinging portions. The combination of the swing part and the swing frequency is not limited to three sets, and may be a plurality of sets other than the three sets. Furthermore, the switching order of the rocking parts can be changed as appropriate according to the user's operation or mode. In FIG. 6, the periods of the swinging parts A, B, and C (corresponding to the width of each swinging part in the time axis direction in FIG. 6) are the swinging execution periods corresponding to the swinging parts. It has become.

  Next, the effect | action of the massage machine 10 of this embodiment is demonstrated. While sitting on the massage machine 10, the user operates the operation unit 34 to adjust the backrest part 13 of the massage machine 10 to a desired reclining angle, and adjusts the ottoman 15 to a desired angle. When the ottoman 15 wishes to swing the leg, the operating portion 34 is first operated to adjust the lift position of the leg support portion 18. When the leg support portion 18 is adjusted to a desired lift position, the operation portion 34 is operated to start swinging the leg support portion 18. The operation method for starting the swinging of the leg support 18 includes a method of selecting a course including a swinging motion of the leg K from a plurality of prepared massage courses, and a swinging motion of the leg K. There is a method of selecting alone.

  The user, for example, the vertical position of the leg support 18, by adjusting in any position ranging in FIG 4 (a) ~ (c), selecting the desired swinging site. When starting the operation of the massage machine 10, the main control unit 30 first acquires the lift position information of the leg support unit 18 via the first control unit 31, and refers to the lift position information (that is, the leg support position information). With reference to the data, the swing frequency F corresponding to the lift position is obtained. Then, the main control unit 30 designates the obtained oscillation frequency F and instructs the oscillation frequency control unit 32 to drive the oscillation drive unit 19. The swing frequency control unit 32 drives the motor 25 at a rotational speed at which the instructed swing frequency F is obtained, and swings the leg support unit 18 at the instructed swing frequency F.

  During the swinging operation of the ottoman 15, it is assumed that the swinging part is switched in the order of A, B, and C, for example, as shown in FIG. 6 by the operation of the operation unit 34 by the user or the setting during the massage course. . In the example of FIG. 6, when the preparatory operation is performed at the oscillation frequency F0 at the beginning of the operation, and then the oscillation part is switched in the order of A, B, C, the ottoman 15 is operated as follows.

  When the leg support 18 is operated at the swinging frequency F2 during the swinging period when the swinging part A is in the swinging part A, when the swinging part A is switched to the swinging part B, the swinging frequency F2 is changed to the swinging frequency F3. Change. The leg support 18 is operated at the swing frequency F3 during the swinging period when the swinging part B is located. Further, when switching from the rocking part B to the rocking part C, the rocking frequency F3 changes to the rocking frequency F1. The leg support 18 is operated at the swing frequency F1 during the swinging period when the swinging portion C is located. As described above, since the swing frequency also changes in accordance with the change of the swing portions A to C, the swing motion of the leg K is not monotonous, and the swing frequency does not change even if the swing portion changes. Higher massage effect can be obtained.

As described above in detail, according to the present embodiment, the following effects can be obtained.
(1) The swing pattern is changed according to the lift position of the leg support 18 that moves along the longitudinal direction of the leg K with respect to the leg support 18 that is provided on the ottoman 15 so as to be swingable in the left-right direction. That is, the swing pattern is changed according to the change of the swinging portion of the leg K. For this reason, the pleasantness suitable for each rocking | fluctuation site | part and the loosening effect can be acquired. Therefore, a higher massage effect can be obtained as compared with a configuration in which the swing pattern does not change even if the swinging portion changes. Further, since the swing pattern changes according to the change of the swinging portion, the user can obtain various feelings of operation.

  (2) The swing frequency is changed according to the lift position of the leg support 18 provided on the ottoman 15. That is, the swing frequency is changed in accordance with the change of the swinging portion of the leg K. For this reason, a higher massage effect can be obtained as compared with a configuration in which the oscillation frequency does not change even if the oscillation part changes.

  (3) A swing pattern in which the swing frequency at each swing portion is constant is employed. For this reason, when it exists in the same rocking | swiveling part, since it is maintained at a fixed rocking | fluctuation frequency, the leg K can be rock | fluctuated by a fixed rhythm and the high massage effect can be acquired.

  (4) Almost simultaneously with the swinging part changing mechanism 23 changing the swinging part, the control means (the main control unit 30 and the swinging frequency control part 32) change the swinging frequency and are suitable for different swinging parts. In addition, since the control is performed at different oscillation frequencies, a pleasant feeling and a loosening effect suitable for each oscillation part can be obtained, and the change point of the oscillation part can be easily felt, and the operational feeling is improved.

(5) Since the leg support 18 is movably provided and the swinging part is changed by changing the support position of the leg, the swinging part changing mechanism 23 can be configured relatively easily.
(Second Embodiment)
Next, a second embodiment will be described with reference to FIG. The second embodiment is different from the first embodiment in that the oscillating frequency of the ottoman 15 is the same even if the oscillating part is different, and different fluctuations according to the oscillating part are given. In addition, the same code | symbol is attached | subjected about the structure similar to 1st Embodiment, and the one part or all part of the description is abbreviate | omitted.

  As shown in FIG. 7, the swing patterns of the swinging portions A, B, and C corresponding to the raising / lowering positions of the leg support 18 have the same swing frequency average value, but the swing frequency swing method is the same. Different. In the example of FIG. 7, in the swing pattern during the swinging period for each of the swinging portions A, B, and C, the average value of the swinging frequency is the same constant value Favg between the swinging portions. Then, the fluctuation width Δf2 of the fluctuation pattern corresponding to the oscillation part A, the fluctuation width Δf1 of the fluctuation pattern corresponding to the oscillation part B, and the fluctuation width Δf3 of the fluctuation pattern corresponding to the oscillation part C are Δf1 <Δf2. <Δf3 is in a magnitude relationship, and is different for each swinging part. The fluctuation widths Δf1 to Δf3 are set to preferable values for each of the oscillation parts A, B, and C obtained experimentally. Note that the fluctuation frequency is the same in the rocking parts A to C, but the fluctuation frequency may be different for each rocking part.

  The main control unit 30 stores, in a memory, reference data indicating a correspondence relationship between the swinging portion, the swinging frequency and the swinging width, and data of the average swinging frequency Favg. The main control unit 30 acquires a fluctuation frequency and a fluctuation width corresponding to the swinging part grasped from the lift position of the leg support part 18 with reference to the reference data. Then, the main control unit 30 designates the average oscillation frequency Favg, the fluctuation frequency, and the fluctuation width Δf, and instructs the oscillation frequency control unit 32 to perform the oscillation control. The oscillation frequency control unit 32 controls the oscillation drive unit 19 so that the oscillation frequency varies for each oscillation part A, B, C according to the instructed contents. Note that the reference data indicates the correspondence between the rocking part and the rocking frequency for one period of fluctuation, and the main control unit 30 specifies the rocking frequency and controls the rocking frequency control unit 32 to perform rocking control. It is also possible to adopt a configuration for instructing. Further, the main control unit 30 designates the fluctuation frequency calculated based on the fluctuation frequency and fluctuation width obtained from the reference data and the average fluctuation frequency Favg, and instructs the fluctuation frequency control unit 32 to perform the fluctuation control. It is good also as a structure.

  (6) According to the second embodiment, as the control in which the change of the swinging part and the change of the swinging pattern are associated with each other, if the swinging part is different, the swinging frequency fluctuation method during the swinging period is different. Control. Therefore, by giving preferable fluctuations obtained experimentally for each of the swinging parts A, B, and C, preferable swinging is given for each swinging part, and the user feels the effect of unraveling by swinging and the feeling of comfort due to the swinging. Can be obtained. Further, since the way of fluctuation changes when the swinging portion changes, various operational feelings can be obtained, and the change of the swinging portion can be easily felt.

(Third embodiment)
Next, a third embodiment will be described with reference to FIG. The third embodiment is different from the above embodiments in that when the swinging portion is changed, both the swinging frequency and the fluctuation are changed. In addition, the same code | symbol is attached | subjected about the structure similar to 1st Embodiment, and the one part or all part of the description is abbreviate | omitted.

  As shown in FIG. 8, the average value of the oscillating frequency during the oscillating period for each of the oscillating parts A, B, and C differs among the oscillating parts, and the fluctuation method of the oscillating frequency also differs between the oscillating parts. To control. In the example of FIG. 8, the swing patterns in the swing execution period for each swing portion A, B, C are F2, F3, and F1, respectively, and the swing width of the swing frequency is Δf2. , Δf1, Δf3 (Δf1 <Δf2 <Δf3). The fluctuation widths Δf1 to Δf3 are set to preferable values for each of the oscillation parts A, B, and C obtained experimentally. In addition, the fluctuation frequency is the same in the rocking parts A and C, and the rocking part B is higher than the fluctuation frequency of the rocking parts A and C. Of course, the fluctuation frequency may be different for each oscillation part.

  The main control unit 30, the memory, and the swinging portion, the average value of the oscillation frequency, and stores the reference data indicating the correspondence relation between fluctuation frequency and fluctuation width. The main control unit 30 acquires the average value, the fluctuation frequency, and the fluctuation width of the oscillation frequency corresponding to the oscillation part grasped from the ascending / descending position of the leg support unit 18 with reference to the reference data. The main control unit 30 designates the average value of the oscillation frequency, the fluctuation frequency, and the fluctuation width Δf, and instructs the oscillation frequency control unit 32 to perform the oscillation control. The swing frequency control unit 32 controls the swing drive unit 19 so that the average value and the swing method of the swing frequency are different for each swing portion A, B, C according to the instructed contents. As the swing control method by the main control unit 30 and the swing frequency control unit 32, the other methods described in the second embodiment can be employed.

  (7) According to the third embodiment, as the control in which the change of the swing part and the change of the swing pattern are associated, if the swing part is different, the swing frequency (average value) in the swing execution period is The control is different in both ways of fluctuation. Therefore, compared with the first embodiment in which only the oscillation frequency is changed and the second embodiment in which only the fluctuation method is changed, it is possible to obtain a higher unraveling effect and comfort that are suitable for each oscillation site. Furthermore, it becomes easier to realize the change of the swinging part, and the user can obtain a variety of operational feelings.

(Fourth embodiment)
Next, a fourth embodiment will be described with reference to FIG. The fourth embodiment is different from the above embodiments in that the oscillation frequency is changed smoothly when the oscillation site is switched. In addition, the same code | symbol is attached | subjected about the structure similar to 1st Embodiment, and the one part or all part of the description is abbreviate | omitted.

  As shown in FIG. 9, the oscillating portion A, B, when C is switched progressively changes from the previous oscillation frequency to a next oscillation frequency. In the example of FIG. 9, when the rocking parts A, B, and C are switched, the rocking frequency is changed at a certain level from a timing slightly before the switching point of the rocking part (vertical broken line in FIG. 9). The oscillation frequency corresponding to the oscillation part is reached at a timing slightly after the switching point of the oscillation part. In other words, the oscillation frequency changes almost simultaneously with the switching of the oscillation part. At this time, the oscillation frequency from the oscillation frequency corresponding to the previous oscillation part to the oscillation frequency corresponding to the next oscillation part. Changes at a constant slope (rate of change in oscillation frequency).

  The main control unit 30 stores in the memory reference data indicating a correspondence relationship between the swinging part and the swinging frequency, and at each swing frequency corresponding to the swinging part before and after switching obtained from the reference data. The fluctuation frequency change rate according to the difference is calculated. The fluctuation rate of the oscillation frequency indicates the amount of change (increase or decrease) of the oscillation frequency per unit time, and takes a positive value when the oscillation frequency is increased, and a negative value when the oscillation frequency is decreased. Take.

  When the main control unit 30 inputs an operation signal for instructing ascending or descending of the leg support unit 18 from the operation unit 34, the swing frequency corresponding to the current swing part and the swing frequency corresponding to the next swing part. The fluctuation frequency change rate is calculated by dividing the difference by a predetermined change execution time. Then, the main control unit 30 first determines the oscillation frequency from the timing before the leg support unit 18 rises or descends and switches to the next oscillation site (for example, just before half the change execution period). It changes with the calculated fluctuation frequency of oscillation frequency. This swing frequency control is performed by the main control unit 30 instructing the swing frequency control unit 32 to determine the swing frequency at that time. As a result, as shown in FIG. 9, the oscillation frequency starts to change from a timing slightly before the switching point of the swinging portion, and reaches the next swinging frequency a little later than the switching point of the swinging portion. The oscillation frequency changes smoothly.

  (8) According to the fourth embodiment, the rocking frequency gradually changes when the rocking portions A, B, and C are switched, so that the rocking frequency is abrupt as in the first embodiment (FIG. 6). Compared to the configuration that changes to, the burden on the body due to the change of the oscillation frequency can be reduced.

(Fifth embodiment)
Next, a fifth embodiment will be described with reference to FIG. In the fifth embodiment, the swing control is performed in which the period in which the swing frequency is changed when the swing part is changed and the period in which the swing frequency is not changed even if the swing part is changed are mixed. Different from each embodiment. In addition, the same code | symbol is attached | subjected about the structure similar to 1st Embodiment, and the one part or all part of the description is abbreviate | omitted.

  FIG. 10 shows the relationship between the time of one massage mode set in the massage machine 10 and the oscillation frequency. This massage mode is divided into a plurality of periods (cycles), and the swinging part changes in the order of A, B, and C in one cycle. In the first cycle, even if the rocking part changes as A, B, C, the rocking frequency is kept constant without changing, and in the second cycle, the rocking part changes as A, B, C. The rocking frequency varies depending on the rocking part.

  In the memory of the main control unit 30, every cycle during the massage mode is the first cycle in which all the rocking parts have the same constant rocking frequency, or the rocking frequency is changed for each rocking part. Setting data in which a flag for determining whether the cycle is two is written is stored. Further, the memory of the main control unit 30 stores reference data indicating the correspondence between the swinging part and the swinging frequency for the second cycle.

  When the massage machine 10 is operated in the massage mode, the main control unit 30 refers to the setting data and the current nth cycle (where n is 1, 2,..., K) is the first cycle. Or whether it is the second cycle. For example, in the first cycle shown in FIG. 10, it is determined from the setting data flag that the cycle is the first cycle, and the main control unit 30 maintains the constant oscillation frequency F2 even if the oscillation portion changes. On the other hand, if it is the second cycle shown in FIG. 10, it is determined that it is the second cycle from the flag of the setting data. Therefore, when the swing part changes, the main control unit 30 refers to the reference data, acquires the swing frequency corresponding to the changed swing part, and changes the ottoman 15 to the swing frequency. Thus, as shown in FIG. 10, in the second cycle, the oscillation frequency changes according to the change of the oscillation part. The same swing control is performed after the third cycle. The swing control is performed by the swing frequency control unit 32 controlling the swing drive unit 19 to the swing frequency designated by the main control unit 30.

  (9) According to the fifth embodiment, there are a cycle (period) in which the oscillation frequency is changed according to a change in the oscillation part during the massage mode, and a cycle (period) in which the oscillation frequency is not changed. The effect of the change in the oscillation frequency can be realized more and the burden on the body with respect to the change in the oscillation frequency is reduced. Moreover, the variation of rocking | fluctuation increases and the higher massage effect is acquired.

(Sixth embodiment)
Next, a sixth embodiment will be described with reference to FIG. The sixth embodiment is different from the above embodiments in that the swinging part changing mechanism is a mechanism that uses a plurality of airbags and changes the support position (gripping position) of the legs by inflating and contracting the airbag. In addition, the same code | symbol is attached | subjected about the structure similar to 1st Embodiment, and the one part or all part of the description is abbreviate | omitted.

  As shown in FIG. 11 (a), the swinging part changing mechanism 40 as the swinging part changing means is a set of left and right sets that can be swung in the left and right directions by the same swinging drive unit 19 as in the first embodiment. A leg support portion 41 (only one is shown in the figure) is provided. However, the leg support portion 41 is fixed to the connection base portion 24 (see FIG. 3), and the length of the leg K in the longitudinal direction is longer than that of the leg support portion 18 of the first embodiment. Inside the leg support portion 41, a plurality of airbags 42 (two pairs in FIG. 11) are arranged along the longitudinal direction of the leg K (vertical direction in FIG. 11) to grip the legs from both the left and right sides. Has been. Each airbag 42 is connected to a discharge port of an air pump 44 through switching valves 43a and 43b. The oscillating frequency control unit 32 (see FIG. 5) selects one set to be inflated among the plurality of sets of airbags 42 by switching the switching valves 43a and 43b while the air pump 44 is driven. Specifically, the switching valve 43a is switched between an air supply position for supplying air to the lower airbag 42a and an exhaust position for exhausting air. The switching valve 43b is switched between an air supply position for supplying air to the upper airbag 42b and an exhaust position for exhausting air.

  The first control unit 31 drives and controls the air pump 44 of the swinging part changing mechanism 40 and controls the switching of the switching valves 43a and 43b. When the operation unit 34 is operated to lower the gripping position of the leg K, the first control unit 31 drives the air pump 44 and switches the switching valve 43a to the air supply position and the switching valve 43b to the exhaust position. . As a result, as shown in FIG. 11A, the lower airbag 42a is inflated and the upper airbag 42b is contracted, and the lower airbag 42a grips the lower part of the lower leg. On the other hand, when the operation unit 34 is operated to raise the gripping position of the leg K, the first control unit 31 drives the air pump 44 and sets the switching valve 43a to the exhaust position and the switching valve 43b to the air supply position. Switch each one. As a result, as shown in FIG. 11B, the lower airbag 42a contracts and the upper airbag 42b inflates, and the upper airbag 42b grips the upper part of the lower leg.

  The electrical configuration related to the swing control in the massage machine 10 of the present embodiment is basically the same as that in FIG. 5, but instead of the swing site changing mechanism 23 in FIG. 40, and the sensor 35 for detecting the support position of the leg K is not provided. The first control unit 31 designates the gripping position of the leg K and outputs control signals for inflating and deflating a plurality of sets of airbags 42a and 42b to the swinging part changing mechanism 40, whereby gripping control by the airbag 42 is performed. I do. For this reason, the 1st control part 31 grasps | ascertains the holding position by the airbag 42 at the time of outputting a control signal. Specifically, when the first control unit 31 designates the lower stage as the gripping position and outputs control signals for inflation and deflation of the airbag 42, the first control unit 31 knows that the lower airbag 42a is in the gripping position. When the upper stage is designated as the gripping position and the control signal for inflation and deflation of the airbag 42 is output, it is grasped that the upper airbag 42b is in the gripping position.

  The main control unit 30 obtains the swing frequency control information necessary for the swing control by referring to the reference data based on the swing portion corresponding to the gripping position of the airbag 42, and designates the swing frequency control information. Then, the swing frequency control unit 32 is instructed to drive the swing drive unit 19. The swing frequency control unit 32 changes the swing frequency according to the change of the swing portion corresponding to the gripping position (swing position). The main control unit 30 and the oscillation frequency control unit 32 are based on the oscillation frequency control information corresponding to the oscillation part acquired from the reference data, and the oscillation shown in any of the graphs of FIGS. Oscillation control is performed with the oscillation pattern corresponding to the part.

  (10) According to the sixth embodiment, since a plurality of sets of airbags 42 provided on the leg support portion 41 are inflated and contracted to change the gripping position of the legs, the swinging part changes with a simple configuration. The mechanism 23 can be realized. Further, since the gripping position (that is, the swinging position) of the leg K is changed by the expansion and contraction of the airbag 42, the swinging position of the leg K can be firmly held as compared with the leg support portion 18 in the first embodiment. In addition, since the airbag-type swinging part changing mechanism 23 is used, it is possible to avoid a situation in which the clothes of the legs are shifted as the leg support 18 is moved up and down. Further, by adopting the swing patterns shown in FIGS. 6 to 10, the same effects as those of the first to fifth embodiments can be obtained when swinging the legs.

(Seventh embodiment)
Next, a seventh embodiment will be described with reference to FIGS. The seventh embodiment is different from each of the embodiments described above in that the rocking portion is changed by changing the rocking fulcrum of the body. In addition, the same code | symbol is attached | subjected about the structure similar to 1st Embodiment, and the one part or all part of the description is abbreviate | omitted.

  As shown in FIG. 12, the massage machine 10 includes a seat portion 12, a backrest portion 13, and an ottoman 15 as in the first embodiment. The ottoman 15 is provided with a leg support portion 18 that can swing in the left-right direction by driving the swing drive portion 19 (see FIGS. 3 and 13) similar to the first embodiment. In Figure 12, the leg support 18, for convenience of explanation, although depicted in a plate shape, in fact has a cross-sectional U-shape in plan view as in the first embodiment. However, the leg support 18 may be a lifting type or a fixed type. Moreover, the leg support part 18 can also be made into the leg support part 41 provided with the airbag 42 of 6th Embodiment.

  In the massage machine 10 of the present embodiment, an airbag 51 is provided on the leg support 18, an airbag 52 is provided on the seat 12, and an airbag 53 is provided on the backrest 13. Each airbag 51-53 can be individually inflated in the direction indicated by the arrow in FIG. Pushing the expanded one corresponding portion of the body of the air bag 51 to 53, i.e. the lower leg, buttocks, one of the back from the back side (rear side). The body is supported at the pushed-up position, and the body support position is changed by selecting the airbag to be inflated, so that the swing support point of the body when the ottoman 15 swings is changed. Each of the airbags 51 to 53 constitutes a part of a support position changing mechanism 55 that changes the support position of the body. Further, the distal end side of the leg support 18 of the present embodiment, the foot can be placed foot placing portion 18b is connected at an angle changeable state with respect to the leg support 18. In FIG. 12, the leg portion 11 of the chair is omitted. In the present embodiment, the support position changing mechanism 55 corresponds to the swinging part changing means, and the airbags 51 to 53 correspond to the plurality of support portions.

  As shown in FIG. 12, the support position changing mechanism 55 is connected to the airbags 51 to 53 via the switching valves 56a, 56b and 56c connected to the airbags 51 to 53 and the switching valves 56a, 56b and 56c. And an air pump 57 for supplying air. By switching the switching valves 56a, 56b, 56c, one or one set to be inflated is selected from the airbags 51-53. The switching valves 56a, 56b, and 56c are switched between an air supply position that supplies air to the corresponding airbag 51, 52, and 53 and an exhaust position that exhausts air. It is also possible to inflate all of the airbags 51 to 53 or to deflate all of them by switching all of the switching valves 56a, 56b, and 56c to the air supply position or switching to the exhaust position. is there.

  As shown in FIG. 13, the main control unit 30, and the second control unit 58 that drives and controls the supporting position change mechanism 55, and the oscillation frequency control unit 32 are electrically connected. The second control unit 58 controls drive control of the air pump 57 constituting the support position changing mechanism 55 and switching control of the switching valves 56a, 56b, and 56c (all of which are shown in FIG. 12).

  The second control unit 58 designates the support position of the body and outputs control signals for the expansion and contraction of the plurality of airbags 51 to 53 to the support position changing mechanism 55, thereby performing support control by the airbags 51 to 53. Do. For this reason, the 2nd control part 58 grasps | ascertains the support position by the airbags 51-53 at the time of outputting a control signal.

  The main control unit 30 acquires the swing frequency control information necessary for swing control by referring to the reference data based on the support position, specifies the swing frequency control information, and controls the swing frequency control unit 32 to swing. The drive control of the dynamic drive unit 19 is instructed. The swing frequency control unit 32 changes the swing frequency according to the change of the swinging part of the body with the swing support point determined from the support position as a fulcrum. The main control unit 30 and the oscillation frequency control unit 32 are based on the oscillation frequency control information corresponding to the oscillation part acquired from the reference data, and the oscillation shown in any of the graphs of FIGS. Oscillation control is performed with the oscillation pattern corresponding to the part.

Next, the effect | action of the massage machine 10 of this embodiment is demonstrated.
When the operation unit 34 is operated to lower the support position of the body S, the second control unit 58 drives the air pump 57 and exhausts the other switching valves 56b and 56c to the supply valve position and the other switching valves 56b and 56c. Switch to each position. As a result, as shown in FIG. 15A, only the airbag 51 of the leg support 18 is inflated and the lower leg is pushed up and supported. In this state where the lower leg is supported, for example, the knee is the swing fulcrum P, and the lower leg and the foot are the swinging parts. When the operation unit 34 is operated to raise the support position of the body S, the second control unit 58 drives the air pump 57, sets the switching valve 56b to the air supply position, and switches the other switching valves 56a and 56c. To each exhaust position. As a result, as shown in FIG. 15 (b), only the airbag 52 of the seat portion 12 is inflated and the heel portion is pushed up and supported. In this case, the buttocks become the swing fulcrum P, and the entire leg becomes the swing portion. When it is desired to make the swinging portion wider, the operation unit 34 is operated to adjust the angle of the chair to a flat state as shown in FIGS. 14 (c) and 15 (c). The operation of raising the support position of the body S is performed by 34. The second control unit 58 that has input this operation signal drives the air pump 57 and switches the switching valve 56c to the air supply position and the other switching valves 56a and 56b to the exhaust position. As a result, as shown in FIG. 15C, in the state where the chair is flat and the body S is in the supine posture, only the airbag 53 of the backrest 13 is inflated, and the back is pushed up and supported. In this case, the back support position is the swing support point P, and the lower half of the body including the waist is the swing part.

  As the support position of the body S changes in this manner, the swing fulcrum P changes, and the swing portion changes accordingly. And in this embodiment, according to the rocking | swiveling part prescribed | regulated from the position (body support position) of what is inflated among the airbags 51-53, the rocking | fluctuation pattern at the time of rocking the ottoman 15 is FIGS. As shown in the graph of FIG. In the case of adopting an airbag-type leg support portion 41 (FIG. 11) as the leg support portion 18, a change in the gripping position of the leg K by the airbag 42 and a support by pushing up the airbags 51 to 53. Changes in position can be combined.

  (11) According to the seventh embodiment, the swing fulcrum P is changed by disposing the plurality of airbags 51 to 53 on the chair and changing the position of the airbag to be inflated to change the support position of the body S. Therefore, the swinging part of the body can be changed with a relatively simple structure. Further, since the swing pattern of the ottoman 15 is changed in response to the change of the swinging part of the body according to the change of the position (body support position) of the airbags 51 to 53 to be inflated, the unraveling effect can be enhanced. . Furthermore, not only the legs, it is possible to a large portion of the body to the swing part is not limited to the leg, the waist, the disentangling effect throughout the body such as the back muscles are obtained. Further, by adopting the swing patterns shown in FIGS. 6 to 10, the same effects as those of the first to fifth embodiments can be obtained when the body swings.

(Eighth embodiment)
Next, an eighth embodiment will be described with reference to FIGS. The eighth embodiment is different from each of the embodiments described above in that the swinging part is changed by changing the tilt angle of a tilting mechanism such as a reclining mechanism to change the posture of the user. In addition, the same code | symbol is attached | subjected about the structure similar to each said embodiment, and the one part or all part of the description is abbreviate | omitted.

  As shown in FIG. 16, the massage machine 10 is provided with six airbags 51 in total, three in the left and right rows, on the leg support portion 18 of the ottoman 15, and four airbags 52 in the seat portion 12. Further, four airbags 53 are provided on the backrest 13. Specifically, the leg support 18 is provided with a pair of left and right airbags 51 in each of the upper, middle, and lower stages. The seat portion 12 includes a pair of left and right airbags 52 on the front side and the rear side. Furthermore, the backrest part 13 is equipped with a pair of left and right airbags 53 in each of the upper and lower stages. In FIG. 16, the leg support portion 18 is drawn in a plate shape for convenience of explanation, but actually has a U-shaped cross section in plan view as in the first embodiment. However, the leg support 18 may be a lifting type or a fixed type. Moreover, the leg support part 18 can also be made into the leg support part 41 provided with the airbag 42 of 6th Embodiment.

  Each airbag 51-53 can be individually inflated and deflated. One of the airbags 51 to 53 inflated pushes up a corresponding part of the body, that is, one of the lower leg, the buttocks, and the back, and the body is supported at the pushed-up part. In accordance with the change in the body support position, the swing fulcrum of the body when the ottoman 15 swings changes. For this reason, each airbag 51-53 grade | etc., Of this embodiment comprises the support position change mechanism 55 similarly to the said 7th Embodiment.

  As shown in FIG. 16, the support position changing mechanism 55 is connected to the first switching valve 61 connected to the plurality (six) of airbags 51 and to the plurality (four) of airbags 52. The second switching valve 62 and the third switching valve 63 connected to a plurality of (four) airbags 53 are provided. Each of the switching valves 61 to 63 includes a switching valve group including a plurality of switching valves that can be switched between an air supply position and an exhaust position where a plurality of connected airbags can be individually inflated and deflated. By switching the switching valves 61 to 63, the six airbags 51, the four airbags 52, and the four airbags 53 can be individually inflated and contracted. In this embodiment, by individually inflating and shrinking each of the airbags provided for each of the leg support portion 18, the seat portion 12, and the backrest portion 13, the combination of the inflated airbags allows the body support position to be changed. In addition to changes, it is also possible to add a twist to the body, for example, by inflating a diagonal airbag.

  The massage machine 10 of this embodiment includes a posture adjustment mechanism 65 shown in FIG. As shown in FIG. 17, the posture adjustment mechanism 65 provided on the lower side of the seat portion 12 includes a first angle adjustment mechanism 71 that changes the tilt angle θ1 of the ottoman 15 (that is, the leg support portion 18) with respect to the seat portion 12. And a second angle adjusting mechanism 76 that changes the tilt angle θ2 of the backrest 13 with respect to the seat 12. The first angle adjustment mechanism 71 includes a first motor 72 serving as a power source, and a first telescopic body 73 having a ball screw 73 a connected to the output shaft of the first motor 72. The first motor 72 is supported by a support frame 75 extending downward from the lower surface of the seat 12 via a support shaft 74 so that the posture can be changed. The end of the first elastic body 73 opposite to the first motor 72 is connected to the leg support 18 so as to be rotatable.

  The first telescopic body 73 expands when the first motor 72 is driven to rotate in the forward direction and the ball screw 73a rotates in the forward direction. As a result, the leg support portion 18 has a direction in which the tilt angle θ1 decreases (that is, a two-dot chain line). Tilt to the ascending side). On the other hand, the first telescopic body 73 contracts when the first motor 72 is driven in reverse and the ball screw 73a rotates in reverse, and this contraction causes the leg support 18 to increase the tilt angle θ1 (indicated by the solid line). Tilt to the descent side.

  On the other hand, the second angle adjustment mechanism 76 includes a second motor 77 serving as a power source and a second telescopic body 78 having a ball screw 78 a connected to the output shaft of the second motor 77. The second motor 77 is supported by the support frame 75 through a support shaft 79 so that the posture can be changed. The end of the second stretchable body 78 opposite to the second motor 77 is connected to the base end of the backrest 13 so as to be rotatable.

  The second telescopic body 78 expands when the second motor 77 is driven to rotate forward and the ball screw 78a rotates forward. As a result, the backrest 13 is raised in a direction in which the tilt angle θ2 decreases (that is, as shown by a solid line). Tilt to the side). On the other hand, the second telescopic body 78 contracts when the second motor 77 is driven in reverse and the ball screw 78a reverses, and this contraction causes the backrest 13 to increase in the tilt angle θ2 (that is, a two-dot chain line). Tilt to the lower side shown).

  The massage machine 10 is adjusted to, for example, the chair posture shown by a solid line in FIG. 17 or the reclining posture shown by a two-dot chain line in FIG. The posture adjusting mechanism 65 is also provided in the first to seventh embodiments. In the present embodiment, the posture adjustment mechanism 65 corresponds to a swinging part changing unit.

  As shown in FIG. 18, the main control unit 30 includes a second control unit 58 that drives and controls the support position changing mechanism 55, a third control unit 66 that drives and controls the attitude adjustment mechanism 65, and the swing drive unit 19. Is electrically connected to the oscillation frequency control unit 32 that controls the driving of the motor. The second control unit 58 controls drive control of the air pump 57 that constitutes the support position changing mechanism 55 and switching control of the switching valves 61 to 63.

  The second control unit 58 designates the support position of the body and outputs control signals for the expansion and contraction of the plurality of airbags 51 to 53 to the support position changing mechanism 55, thereby performing support control by the airbags 51 to 53. Do. For this reason, the 2nd control part 58 grasps | ascertains the support position of the body by the airbags 51-53 at the time of outputting a control signal.

  When the main control unit 30 receives the posture adjustment instruction signal from the operation unit 34, the main control unit 30 instructs the third control unit 66 to drive the posture adjustment mechanism 65 to adjust the posture instructed by the signal. The posture adjustment mechanism 65 is provided with a sensor 67 that can individually detect the tilt angle θ1 of the ottoman 15 (that is, the leg support portion 18) and the tilt angle θ2 of the backrest portion 13. For example, an angle sensor is used as the sensor 67. When the third control unit 66 is operated in a direction in which the backrest unit 13 is tilted backward, the third control unit 66 tilts the backrest unit 13 and the ottoman 15 to the side indicated by a two-dot chain line in FIG. 17, while the backrest unit 13 rises up. When it is operated, the backrest 13 and the ottoman 15 are tilted to the side indicated by the solid line in FIG. The tilt angles θ1 and θ2 at this time are acquired from the detection values of the sensor 67.

  The main control unit 30 acquires the tilt angles θ1 and θ2 detected by the sensor 67 via the third control unit 66, and determines the posture of the massage machine 10 based on the tilt angles θ1 and θ2. For example, the main control unit 30 makes the chair posture shown in FIG. 19 (a) (θ2 is “small” posture) or tilts slightly as shown in FIG. 19 (b) based on the tilt angles θ1 and θ2. It is determined whether it is a relaxed posture (θ2 is “medium” posture) or a lining posture (sleeping posture) (θ2 is “large” posture) shown in FIG. Due to the difference in posture, the swinging point P of the body when the ottoman 15 is swung in the left-right direction is changed, and the swinging part of the body is changed by the change of the swinging support point P. The posture may be determined only from the tilt angle θ2 of the backrest 13 with respect to the seat 12 out of the tilt angles θ1 and θ2.

  For example, when the massage machine 10 is in the chair posture shown in FIG. 20 (a), the rocking fulcrum P of the body S is located at the knee, and the lower leg and the foot are the rocking parts. In the relaxed posture shown in FIG. 20B, the swing support point P of the body S is located at the buttocks, and the entire leg portion becomes the swing portion. Furthermore, when in the lining posture shown in FIG. 20C, the swinging fulcrum P of the body S is located at the upper back, and almost the whole body (specifically, the range from the upper back to the toes) is the swinging part. . The swing fulcrum P shown in FIG. 20 is an example because the swing fulcrum P changes depending on the posture of the massage machine 10 and other factors such as cushioning properties of the seat 12 and the backrest 13. Only.

  The main control unit 30 shown in FIG. 18, the memory stores the posture determined by the tilt angle .theta.1, .theta.2, the reference data indicating the correspondence relationship between the shaking pattern. Based on the posture (tilt angles θ1, θ2), the main control unit 30 acquires the swing frequency control information necessary for swing control with reference to the reference data, and the swing frequency based on the swing frequency control information. The control unit 32 is instructed to control the swing drive unit 19. Oscillation frequency control unit 32, in response to a change in the oscillating part of the body to pivot the swing fulcrum P which is determined from the position, to vary the oscillation frequency.

Next, the effect | action of the massage machine 10 of this embodiment is demonstrated.
When an operation for changing the posture is performed by the operation unit 34, the third control unit 66 drives the motors 72 and 77 in accordance with an instruction from the main control unit 30. When the massage machine 10 is in the chair position shown in FIG. 19A, as shown in FIG. 20A, the swinging fulcrum P is the knee, and the lower leg and the foot are the swinging parts. When the massage machine 10 is in the relaxed posture shown in FIG. 19 (b), as shown in FIG. 20 (b), the rocking fulcrum P becomes the buttocks and the entire leg becomes the rocking portion. Further, when the massage machine 10 assumes the lining posture shown in FIG. 19C, the swing fulcrum P is the upper back as shown in FIG. 20C, and the whole body is the swinging portion.

  The main control unit 30 determines the posture based on the tilt angles θ1 and θ2 detected by the sensor 67, refers to the reference data based on the determined posture, acquires the swing frequency control information corresponding to the posture, The oscillation frequency control information is designated and the oscillation frequency control unit 32 is instructed to drive the oscillation drive unit 19. The swing frequency control unit 32 performs swing control of the ottoman 15 with different swing patterns corresponding to changes in posture.

  In the example in which the swing patterns shown in the graphs of FIGS. 6 to 10 are employed, the swinging parts are the lower leg and the foot as shown in FIG. 20A according to the posture, and in FIG. 20B. As shown in FIG. 20C, the ottoman 15 swings with different swing patterns as shown in the graphs for the entire leg portion and for the substantially whole body as shown in FIG.

  Further, in the present embodiment, the swing fulcrum P changes more variously depending on the combination of the body support position defined from the position of the airbag to be inflated among the airbags 51 to 53 and the posture by the posture adjusting mechanism 65. To do. The reference data stored in the memory by the main control unit 30 includes correspondence between the body swinging position determined by the combination of the body support position by the airbags 51 to 53 and the posture by the posture adjusting mechanism 65 and the swing pattern. Relationships are also set. Further, in the case of adopting a leg support 41 (FIG. 11) having an airbag 42 as the leg support 18, the reference data stored in the memory by the main control unit 30 includes the leg K by the airbag 42. The correspondence relationship between the swinging part of the body and the swing pattern determined from the combination of the grip position, the body support position by the airbags 51 to 53, and the posture by the posture adjustment mechanism 65 is set. When the main control unit 30 specifies the swing part, the main control unit 30 obtains swing frequency control information corresponding to the swing part with reference to the reference data, designates the frequency control information, and controls the swing frequency control unit 32.

Further, in the seventh, eighth, eleventh and twelfth embodiments, the ottoman 15 of the first or sixth embodiment may be adopted.

  In the seventh, eighth, eleventh and twelfth embodiments, as a plurality of support portions provided on the body support surface side of the chair (chair type massage machine) so as to be able to protrude and retract, the airbag 51 However, the present invention is not limited to a gas bag that is inflated (protruded) or contracted (retracted) by a gas such as air, but may be a fluid bag including a liquid bag that is inflated and contracted by a liquid such as water or oil. . Further, the swinging portion changing means may be configured by adopting a plurality of support portions that protrude and retract with the power of an actuator such as a cylinder or solenoid.

  The change of the swinging part and the change of the swinging pattern are not limited to being simultaneous, and the switching timing of the swinging part and the switching timing of the swinging pattern may be substantially the same with a slight shift. For example, on the basis of an operation signal from the operation unit 34, the driving of the swinging part changing means is started and the change of the swinging part is started after a slight time lag from the start of the change of the swinging part. Based on the operation signal, the oscillation part changing means may be started after a slight time lag after the oscillation frequency is first changed.

  In the second embodiment (FIG. 7) and the third embodiment (FIG. 8), the larger the swinging part (that is, the longer the swinging arm length), the larger the fluctuation width, but on the contrary The fluctuation width may be increased as the swinging portion is smaller (that is, the swinging arm length is shorter).

  The fluctuation of the oscillation frequency as shown in FIGS. 7 and 8 is not limited to the fluctuation of a curved waveform such as a sine wave. For example, the fluctuation may be a rectangular wave or a triangular wave.

May be set. Further, the change rate (slope) of the oscillation frequency may be constant regardless of the difference between the oscillation frequencies before and after switching. Furthermore, the trajectory for gradually changing the oscillation frequency may be a curved line instead of a constant inclination.

In the second, third, and fifth embodiments (FIGS. 7, 8, and 10), the swing pattern may be gradually changed when the swinging portion is changed.
In the fifth embodiment, in the cycle in which the swing pattern is changed in response to the change of the swinging part, instead of the swinging frequency, only the swinging method (at least one of the swinging width and the swinging frequency) or the swinging frequency And the way of fluctuation may be changed in accordance with the change of the swinging part.

  ・ It is not necessary for the swing patterns to be different between different swinging parts. It is sufficient that at least two of the plurality of swinging portions have different swing patterns. In the first, third to fifth embodiments (FIG. 6, FIG. 8 to FIG. 10), when the swinging portion is changed, the swing frequency is changed so that the average value of the swing frequency during the swinging period is different. However, it is sufficient that at least two of the plurality of swinging portions have different swinging frequencies (at least an average value). In the second and third embodiments (FIGS. 7 and 8), it is sufficient that at least two of the plurality of swinging portions have different fluctuation widths. For example, when the operation unit 34 is continuously operated to change the swinging part, the swing patterns of the swinging parts A and B (at least two) are different in the configuration in which the swinging parts A, B, and C change in order. If so, the rocking portions A and C may have the same rocking frequency.
