Have.

  Each support surface 5a is a rectangular divided seat surface in which the entire seat surface is divided (divided into two). In other words, one seating surface of the seat body is divided (divided into two parts). Thereby, one seat main-body part (main-body part) 30 in which a user sits is comprised by a pair of adjacent division | segmentation part 5, and one seat surface is comprised by a pair of support surface 5a. As described above, the plurality of support surfaces 5a share and support a predetermined continuous region (here, the buttocks and the thighs) in the user's body. Although not shown, each divided portion 5 may be configured to be covered with a cushion member and a cover member. Or a pair of division | segmentation part 5 may be put together and it may be covered with one cover member with elasticity. The seat body portion 30 is a portion of the seat portion 1 that can contact a user (via the cover member) and receive a treatment portion.

  In FIG. 18 and FIG. 19, the reciprocating base portion 6 has each of the divided portions 5 attached so as to be reciprocally movable in the in-plane direction of the support surface 5a. In addition, in the state (initial state) of FIG. 1, each of the division parts 5 is movable in the front-rear direction. The reciprocating base portion 6 has a plurality (four) of moving blocks 17 attached to the lower surface (back surface) of each divided portion 5. The moving block 17 is provided at four locations, front, rear, left and right. Each moving block 17 is formed with a slide hole 17 a penetrating in parallel with the longitudinal direction of the dividing portion 5.

  The reciprocating base portion 6 further includes a base member 18 serving as a frame member, and four support shafts 41 fixed to the base member 18 with the front-rear direction as a longitudinal direction. Two adjacent support shafts 41 are for supporting one divided portion 5. One support shaft 41 is inserted through the slide hole 17a of the pair of moving blocks 17 at the front and rear, and supports the moving block 17 so as to be slidable. With this configuration, each of the pair of divided portions 5 can freely reciprocate and slide relative to the single base member 18.

  The reciprocating drive unit 7 can reciprocate each of the pair of divided units 5. For this purpose, the reciprocating drive unit 7 includes a motor 19 fixed to the base member 18 and an arm 20 that is connected to the motor 19 via a power transmission unit 42 and is operated by the motor 19. One motor 19 is provided at a position below the dividing unit 5, and this motor 19 drives both the left and right arms 20, 20. The power transmission unit 42 includes a reduction gear unit 47 that reduces the rotational speed of the motor 19, a rotation shaft 44 that is linked to the reduction gear unit 47, extends to the left and right sides, and is rotated around its axis by the rotational power of the motor 19, A rotating portion 45 that rotates eccentrically with respect to the axis of the rotating shaft 44 is provided. The arm 20 includes a first arm 43a, a second arm 43b, and a third arm 43c. One end portion of the first arm 43a is rotatably attached to the back surface of the dividing portion 5, and the other end portion and one end portion of the second arm 43b are rotatably attached. The other end of the second arm 43b is rotatably attached to a shaft 46 attached to the base member 18 in the left-right direction. One end portion of the third arm 43c is pivotally attached to the middle portion of the second arm 43b, and the other end portion is pivotally attached to the rotating portion 45.

According to the reciprocating base portion 6 and the reciprocating drive portion 7 as described above, when the other end portion of the third arm 43c rotates eccentrically by the rotation of the motor 19, the dividing portion 5 is interposed via the second and first arms 43b and 43c. Can be reciprocated linearly along the support shaft 41. Thereby, the pair of left and right divided portions 5 can reciprocate in the front-rear direction.
Although not shown, a motor 19 for driving the arm 20 connected to the left dividing unit 5 and a motor 19 for driving the arm 20 connected to the right dividing unit 5 can be provided. In this case, as in FIG. 19, one motor 19 drives one (left) arm 20, and the other motor 19 drives the other (right) arm 20. Each can reciprocate independently in the front-rear direction.

  In FIG. 24, the main control portion 58a for the seat portion 1 of the control device 8 controls the operation of the reciprocating drive portion 7 (motor 19) as the first drive portion A1. Specifically, the main control unit 58a controls the forward and reverse rotation directions, rotation start, and rotation stop of the motor 19. As shown in FIG. 19, the phase of the pair of rotating parts 45 (positions attached eccentrically) with respect to the rotating shaft 44 (180 °) is different (180 °), which is shown in the plan view of the chair of FIG. 3. As shown in the figure, it is possible to continue the reciprocating motion by starting the movement of the one divided portion 5 and the other divided portion 5 in different directions and not synchronizing them. In the plan view of the chair in FIG. 3, the leg rest is omitted.

Further, when the motor 19 for the left dividing unit 5 and the motor 19 for the right dividing unit 5 are provided (not shown), for example, the main control unit 58a has one dividing unit. By controlling the motor 19 for 5 and the motor 19 for the other splitting section 5, one splitting section 5 and the other splitting section 5 start to move in the same direction, and reciprocate in a synchronized state. Can be continued. Alternatively, as shown in the plan view of the chair in FIG. 3, the movement of one of the divided portions 5 and the other divided portion 5 in different directions may be continued and the reciprocating motion may be continued in a state where they are not synchronized. it can.
The synchronized state means that both the period and the phase are in the same state (the same operation) when each of the pair of division parts 5 reciprocates (repetitively moves), and the state in which the synchronization is not performed. Means that one or both of the period and the phase are different (different operations). When the other dividing unit 5 is moved in a state where one dividing unit 5 is stopped, it is included in a state where the other dividing unit 5 is not synchronized.

  In this way, the massage mechanism has a pair of divided portions 5, and the reciprocating drive portion 7 controlled by the main control portion 58 a for the seat portion 1 of the control device 8 allows each of these divided portions 5 to be (independently). ) It can be reciprocated. For this reason, in the seat part 1, one division | segmentation part 5 and the division | segmentation part 5 different from this can perform different operation | movement. Thereby, the operation | movement which shakes a to-be-treated part (a buttocks and a thigh) can be made into a complicated operation | movement.

  FIG. 2 is a view showing a modification of the massage mechanism of the present invention, and is a cross-sectional view of the seat 1 as viewed from the side. 1 and 2, the massage mechanism, the divided part 5 divided into two parts, and the reciprocating base part (moving base part) 6 attached so that each of the divided parts 5 can be repeatedly moved. And a reciprocating drive unit 7 that moves each of the divided units 5 independently. The two divided portions 5 are provided adjacent to each other on the same surface (the same horizontal plane), and the reciprocating base portion 6 and the reciprocating drive portion 7 are provided below these divided portions 5. In this embodiment as well, the repetitive motion is reciprocating movement (reciprocating linear movement), and the reciprocating base portion 6 is attached to each of the divided portions 5 so as to be reciprocally movable. Each of the division parts 5 is reciprocated independently.

  The upper surface (surface) of each divided portion 5 is a support surface 5a that supports the user's treatment portion, that is, the buttocks and thighs from below. Each division part 5 is a planar view rectangle. In FIG. 1, each divided portion 5 has a length from the backrest portion 2 to the leg rest portion 3 in the longitudinal direction (front-rear direction). Each divided portion 5 has a length substantially equal to or smaller than the half length of the dimension between the pair of armrest portions 15 and 15 in a direction (left-right direction) orthogonal to the longitudinal direction. ing.

  Each support surface 5a is a rectangular divided seat surface in which the entire seat surface is divided (divided into two). In other words, one seating surface of the seat body is divided (divided into two parts). Thereby, one seat main-body part (main-body part) 30 in which a user sits is comprised by a pair of division | segmentation part 5, and one seat surface is comprised by a pair of support surface 5a. Although not shown, each divided portion 5 may be configured to be covered with a cushion member and a cover member. Or a pair of division | segmentation part 5 may be put together and it may be covered with one cover member with elasticity. The seat body portion 30 is a portion of the seat portion 1 that can contact a user (via the cover member) and receive a treatment portion.

The reciprocating base portion 6 has each of the divided portions 5 attached in a reciprocating manner in the in-plane direction of the support surface 5a. In addition, in the state (initial state) of FIG. 1, each of the division parts 5 is movable in the front-rear direction. In FIG. 2, the reciprocating base portion 6 includes a moving block 17 attached to the lower surface (back surface) of the dividing portion 5 and a base member 18 that supports the moving block 17 by sliding.
The moving block 17 is formed with a slide hole 17 a penetrating in parallel with the longitudinal direction of the dividing portion 5. Two slide holes 17a are formed vertically. Further, the moving block 17 is formed with a guide hole 17b which is a long hole which is long in the vertical direction and has a depth direction in a direction perpendicular to the penetrating direction of the slide hole 17a.

  The base member 18 has a pair of shafts 18a on the upper and lower sides through which the guide hole 17a is inserted, and a fixing member 18b that fixes the shafts 18a at both ends. This pair of upper and lower shafts 18 a guides one of the divided portions 5. Another pair of upper and lower shafts 18a for the other divided portion 5 are fixed to the same fixing member 18b in a state of being adjacent to each other. With this configuration, each of the pair of divided portions 5 can freely reciprocate and slide relative to the single base member 18.

  The reciprocating drive unit 7 can independently reciprocate each of the pair of divided units 5. For this purpose, the reciprocating drive unit 7 includes a pair of motors 19 and an arm 20 that is connected to each motor 19 and operates. One motor 19 is provided at a position below one of the dividing sections 5, and this motor 19 rotates the arm 20. In addition, another motor 19 is provided at a position below the other divided portion 5, and this motor 19 rotates another arm 20. A pin 20a is provided at the tip of each arm 20, and the pin 20a is inserted into the guide hole 17b.

  According to the reciprocating base unit 6 and the reciprocating drive unit 7 as described above, when each arm 20 is rotated by the rotation of each motor 19, the pin 20a pushes the moving block 17 while moving in the guide hole 17b. Thereby, the moving block 17 can perform a reciprocating linear motion along the shaft 18a. Thereby, the pair of left and right divided portions 5 can independently reciprocate in the front-rear direction.

  In FIG. 24, the main control portion 58a for the seat portion 1 of the control device 8 controls the operation of the reciprocating drive portion 7 (motor 19) as the first drive portion A1. Specifically, the main control unit 58a controls the forward and reverse rotation directions, rotation start, and rotation stop of the motor 19. For example, the main control unit 58a controls the motor 19 for one division unit 5 and the motor 19 for the other division unit 5 so that one division unit 5 and the other division unit 5 are placed in the same direction. The movement is started and the reciprocating motion is continued in a synchronized state. Alternatively, as shown in the plan view of the chair in FIG. 3, the reciprocating motion can be continued in such a manner that the one divided portion 5 and the other divided portion 5 start to move in different directions and are not synchronized. In the plan view of the chair in FIG. 3, the leg rest is omitted. The synchronized state means that both the period and the phase are in the same state when each of the pair of division parts 5 reciprocates (repetitively moves), and the unsynchronized state means the period And one or both of the phases are different from each other. When the other dividing unit 5 is moved while one dividing unit 5 is stopped, it is included in a state where the other dividing unit 5 is not synchronized.

  In this way, the massage mechanism has a pair of divided portions 5, and the reciprocating drive portion 7 controlled by the main control portion 58 a for the seat portion 1 of the control device 8 reciprocates these divided portions 5 independently. Can be moved. Therefore, in the seat part 1, one division | segmentation part 5 and the division | segmentation part 5 different from this can perform different operation | movement. Thereby, the operation | movement which shakes a to-be-treated part (a buttocks and a thigh) can be made into a complicated operation | movement.

  Moreover, in each of the form of this FIG. 2 and the form of the said FIG. 18 (FIG. 19), a massage mechanism is a single axis C of the direction which crosses a pair of division part 5 to the support surface 5a (for example, orthogonal). It further has a rotation support portion 9 that can rotate around. The axis C is a line extending in the direction toward the body. In the case of the seat portion 1, the axis C is an axis in the vertical direction, exists between the pair of divided portions 5, and extends in the longitudinal direction of the divided portions 5. It exists in the center position. The rotation support unit 9 includes a rotation base unit 10 in which a pair of division units 5 are rotatably mounted around an axis C, and a rotation drive unit that can rotate the pair of division units 5 as a unit. 11.

The rotation base portion 10 is attached to the chair body portion 4 in a fixed state.
The configuration of the rotation base unit 10 is the same in each of the configuration of FIG. 2 and the configuration of FIG. 18 (FIG. 19), and a specific configuration will be described with reference to FIG.
The rotation base portion 10 is a plate-like member provided at a position below the dividing portion 5. An annular bearing 21 (see FIG. 3) is interposed between the rotating base portion 10 and the base member 18. And the rotation base part 10 is supporting the said base member 18 so that it can freely rotate to the surroundings of the axis line C via the annular bearing 21 (refer FIG. 3). Further, as described above, the base member 18 supports the pair of divided portions 5 so as to be able to reciprocate. For this reason, when the base member 18 rotates with respect to the rotation base part 10, a pair of division | segmentation part 5 is simultaneously rotated in the same direction. The reciprocating drive unit 7 (motor 19 and arm 20) is attached to the base member 18 so as to rotate together with the base member 18.

  The rotation drive unit 11 includes a motor (power generation unit) 12, a pinion 23 that is rotated by the rotational driving force of the motor 12, and an arc shape (or an annular shape) that is attached to the base unit 18 and meshes with the pinion 23. A gear 24 (see FIG. 3), and a clutch (switching unit) 25 interposed between the motor 12 and the pinion 23. The clutch 25 includes a power transmission state in which the base member 18 supporting the dividing portion 5 is rotated by receiving the rotational driving force from the motor 12, and the base member 18 supporting the dividing portion 5 is free from the axis C. It is possible to switch between a free state in which it can freely rotate. That is, when the clutch 25 is in the power transmission state, the pair of split portions 5 can be rotated around the axis C by the rotation of the motor 12. Further, in this power transmission state, when the rotation of the motor 12 is stopped, the base member 18 is in a fixed (restrained) state that cannot rotate with respect to the rotation base portion 10. On the other hand, when the clutch 25 is in a free state, the pair of split portions 5 can freely rotate around the axis C. The switching of the state of the clutch 25 is performed by the main control portion 58a for the seat portion 1 of the control device 8 (see FIG. 24).

  According to such a rotation support part 9, the direction of the reciprocating linear motion of the pair of division parts 5 can be changed by making the pair of division parts 5 rotatable. For example, the pair of divided portions 5 (FIG. 3) that were movable in the front-rear direction are rotated around the axis C by the rotation drive unit 11, and the longitudinal direction of the divided portion 5 is defined as the oblique front-rear direction. Thereby, as shown in FIG. 4, the division part 5 inclines to the right side and can reciprocate. Thus, by rotating the pair of divided portions 5 as a unit around the axis C, the direction in which the divided portions 5 reciprocate can be forcibly changed. Thereby, the operation | movement which shakes the to-be-treated part of the user who seated on the seat part 1 can be made still more complicated operation | movement.

  Further, as shown in FIG. 1, a cutout portion 22 is formed in the armrest portion 15 as a space for the seat body portion 30. By entering a part of the rotating dividing portion 5 into the cutout portion 22, it is possible to prevent the dividing portion 5 from interfering with the armrest portion 15. In addition, a space (not shown) exists under the backrest 2 to prevent interference with the rotating dividing portion 5. Or the backrest part 2 has a flexible member (not shown) in the lower part, and when this flexible member contacts with the dividing part 5 to rotate, it will be elastically deformed and rotation of the said dividing part 5 will be carried out. It can also be set as the structure which does not inhibit.

  In addition, a state (state of FIG. 1) in which the pair of division parts 5 are aligned at the same position in the longitudinal direction and the longitudinal direction is the front-rear direction of the chair is referred to as an initial state. From this initial state, based on the control of the control device 8, the reciprocating drive unit 7 reciprocates each of the pair of divided units 5 in the longitudinal direction, or the rotational drive unit 11 moves the pair of divided units 5 along the axis C. It can be rotated around. And the control apparatus 8 has a sensor part (not shown) which detects the movement position of each division part 5, and a rotation position. For this reason, the control device 8 can automatically return the pair of divided portions 5 to the initial positions by using the reciprocating drive portion 7 and the rotation drive portion 11. Therefore, it is preferable that the motor 19 of the reciprocating drive unit 7 and the motor 12 of the rotational drive unit 11 are servo motors.

  Moreover, the seat part 1 further has a press part which presses a user's body. In FIG. 1, this pressing portion is an air cell 14 that expands and contracts by supplying and discharging air. An air cell 14 is provided in each of the pair of divided portions 5 constituting the seat body portion 30. The air cells 14 are provided at both ends in the longitudinal direction (front-rear direction in FIG. 1) of each divided portion 5. Each air cell 14 is connected to an air supply device (not shown) provided in the chair body 4 via a pipe. Each air cell 14 expands when air is supplied from the supply device, and can push the user upward. Note that the operation of the supply device is controlled by the control device 8.

[Second Embodiment]
5-8 is a top view which shows 2nd Embodiment of a chair. In the second embodiment, the shape of the dividing unit 5 is different from that of the first embodiment, but the others are the same. In the second embodiment, when the seat main body 30 is viewed from the direction of the axis C (in plan view), the pair of divided portions 5 (seat main body 30) are circular in the initial state. That is, the shape of one divided portion (divided seat portion) 5 is a semicircular shape. A pair of divided portions 5 in the initial state forms one circle. The center of this circle is located on the axis C.

  Also in this chair, it has the rotation support part 9 (refer FIG. 2) which can rotate the division | segmentation part 5 to the periphery of the axis line C. FIG. When the pair of divided portions 5 in the initial state rotate around the axis C, the divided portions 5 have a size that does not interfere with other portions (for example, the lower portion of the backrest portion 2 or the armrest portion 15). Yes. For this reason, a pair of division | segmentation part 5 can rotate 360 degrees, without a rotation angle being restrict | limited. Then, as shown in FIG. 7, the pair of split portions 5 are moved by the reciprocating base portion 6 and the reciprocating drive portion 7 (see FIG. 2) in a state where the longitudinal direction is an oblique front-rear direction. It can reciprocate in the longitudinal direction. Further, as shown in FIG. 8, the pair of divided portions 5 can reciprocate in the longitudinal direction in a state where the longitudinal direction is the left-right direction.

[Third Embodiment]
FIG. 9 is a perspective view showing a third embodiment of the chair. FIG. 10 is a cross-sectional view of the massage mechanism provided in the seat portion of the chair as viewed from the side. This chair is different from the first embodiment (FIG. 1 or FIG. 18) in the shape of the seat body 30, but the rest is the same. That is, in the first embodiment, the entire seat body 30 on which the user is seated among the seats 1 is configured by only a pair of split parts (split seats) 5. In the third embodiment, the entire seat body 30 is composed of a pair of divided portions 55 and an edge portion 26 around the divided portions 55. The edge 26 is annular as shown in FIG. 9, and a rectangular opening is formed at the center. As shown in FIG. 10, the edge portion 26 is erected from the rotation base portion 10. For this reason, this chair has the said rotation support part 9, Even if a pair of division | segmentation part 55 rotates by this rotation support part 9, the edge part 26 does not rotate.

  And this massage mechanism is similar to 1st Embodiment (FIG. 1 or FIG. 18), and the reciprocating base part 6 which attached each of a pair of division | segmentation part 55 so that reciprocation is possible, and these division | segmentation parts 55 And a reciprocating drive unit 7 that reciprocally moves each independently. Then, the movement of one of the divided portions 55 and the other divided portion 55 can be started in the same direction, and the reciprocating motion can be continued in a synchronized state. Or as shown in the top view of the chair of FIG. 11, the movement of one division part 55 and the other division part 55 is started in different directions, and the reciprocating motion can be continued in a state where they are not synchronized. In the plan view of the chair in FIG. 11, the leg rest is omitted.

  Further, as in the first embodiment (FIG. 1 or FIG. 18), in FIG. 10, the seat portion 1 has a single axis C in a direction intersecting (orthogonal) the pair of divided portions 55 with the support surface 55a. It further has a rotation support portion 9 that can rotate around. The rotation support unit 9 includes a rotation base unit 10 in which a pair of divided units 55 are rotatably mounted around an axis C, and a rotation drive unit that can rotate the pair of divided units 5 together. 11. Thereby, the rotation support part 9 changes the direction of the reciprocating linear motion of the pair of split parts 55. For example, in FIG. 11, by rotating the dividing portion 55 that was movable in the front-rear direction around the axis C, the longitudinal direction of the dividing portion 55 is the diagonal front-rear direction as shown in FIG. 12. Thus, the dividing portion 55 is tilted to the right and can be reciprocated. As described above, the rotation driving unit 11 integrally rotates the pair of divided parts 5 around the axis C, whereby the moving direction of the divided parts 5 can be forcibly changed. Thereby, the operation | movement which shakes a to-be-treated part (a buttocks and a thigh) can be made into a complicated operation | movement.

  A gap serving as a space for the reciprocating movement and rotation of the dividing portion 55 is formed between the dividing portion 55 and the edge portion 26 so that the dividing portion 55 can reciprocate and rotate. ing. The gap is preferably provided with a deformable member (not shown) that can be easily deformed. When the dividing portion 55 reciprocates and rotates, the dividing portion 55 elastically deforms the deforming member. Examples of the deformable member include foamed resin. Thus, by interposing a deformation member in the gap between the divided portion 55 and the edge portion 26, the deformation member constitutes a part of the seat body 30. This prevents the user sitting on the seat 1 from feeling uncomfortable due to the gap.

[Fourth Embodiment]
FIG. 13: is a top view which shows 4th Embodiment of the chair of this invention. This embodiment is different from the third embodiment (FIG. 11) in terms of the shapes of the dividing portion 5 and the edge portion 26 (seat body portion 30), but the other portions are the same. In the fourth embodiment, when the seat main body 30 is viewed from the direction of the axis C (in plan view), the edge 26 is formed with a circular opening at the center thereof. A pair of divided portions (divided seat portions) 55 are provided in the opening. The pair of divided portions 55 are circular in the initial state. That is, the shape of one divided portion 5 is a semicircular shape. The center of one circle formed by the pair of divided portions 5 in the initial state is configured on the axis C.

  This chair also has a rotation support portion 9 (see FIG. 10) that enables the division portion 55 to rotate about the axis C, as described above. Therefore, in the fourth embodiment, when the pair of divided portions 55 in the initial state are rotated around the axis C, the divided portions 55 do not interfere with the edge portion 26. For this reason, a pair of division part 55 can rotate 360 degrees, without a rotation angle being restricted. And a pair of division | segmentation part 55 can reciprocate to the longitudinal direction with the said reciprocating base part 6 and the said reciprocating drive part 7 in the state which made the longitudinal direction the diagonal front-back direction (not shown). . Further, the pair of divided portions 55 can be reciprocated in the longitudinal direction by the reciprocating base portion 6 and the reciprocating drive portion 7 in a state where the longitudinal direction is the left-right direction (not shown).

  Also, modifications of the third embodiment and the fourth embodiment will be described. In FIG. 10, the edge portion 26 is attached to the rotating base portion 10. However, although not shown, the edge portion 26 may be attached to the outer peripheral edge portion of the base member 18. In this case, since the base member 18 can rotate around the axis C with respect to the rotation base portion 10, the edge portion 26 rotates around the axis C together with the pair of divided portions 55. Even when the edge portion 26 rotates around the axis C, the notch portion 22 is formed as a space for the seat body portion 30 in the armrest portion 15 as in the first embodiment (FIG. 1). By entering the rotating edge 26 into the notch 22, it is possible to prevent the edge 26 from interfering with the armrest 15. In addition, there is a configuration in which a space (not shown) exists under the backrest portion 2 to prevent interference with the edge portion 26, or the lower portion of the backrest portion 2 is in contact with the edge portion 26. Then, it is preferable to have a structure having a flexible member (not shown) that is elastically deformed and does not hinder the rotation of the edge portion 26.

[Explanation of division unit operation]
In each embodiment of the chair configured as described above, the operation of the dividing portion 5 (55) in the seat portion 1, that is, the operation of shaking the user's treated portion by the dividing portion 5 (55) will be described. . Below, the rocking | fluctuating operation | movement in the chair of 1st Embodiment (FIGS. 1-4 or FIGS. 18-19) is demonstrated as a representative.

  The control device 8 in FIG. 24 includes a programmable microcomputer having a CPU, a memory (RAM), and a storage device (ROM), and performs control processing for operation control of each operating part. The control device 8 stores a program for executing predetermined functions in the storage unit 8b. The control device 8 includes a main control unit 58a that controls each part that operates and a later-described operation selection unit 8a as functional units executed by the program.

  The operation of the reciprocating drive unit 7 (first drive unit A1) and the operation of the rotation drive unit 11 (second drive unit A2) for moving the dividing unit 5 are the main control unit for the seat unit 1 of the control device 8. 58a. Further, the control device 8 includes a storage unit 8b, and the storage unit 8b stores a plurality of operation programs for performing an operation in which the dividing unit 5 swings. The main control unit 58a operates the reciprocating drive unit 7 and the rotation drive unit 11 in accordance with each operation program. The operation program is selected by a user operating the selection button on the controller. Alternatively, the operation program is included in a massage program (massage course) performed by the massage device (treatment unit 16). Then, the operation program is executed by executing the selected massage program.

  The operation selection unit 8 a switches the pair of division units 5 to a synchronized state or a non-synchronized state and causes the reciprocating drive unit 7 to reciprocate. The selection of these two states by the operation selection unit 8a is automatically performed according to the operation program. As a specific example, a case will be described in which a certain operation program is selected, and the operation program includes a portion (step) for reciprocating the pair of division units 5 without synchronizing them. As shown in FIG. 14A, each of the pair of divided portions 5 in the initial state is started to move in different directions (forward and backward) by the reciprocating drive portion 7 so that the phases of both are changed. The reciprocation is continued by making the difference between the two periods the same.

That is, when one (right) dividing unit 5 moves forward, the other (left) dividing unit 5 is 180 degrees out of phase so that it moves backward. Accordingly, as shown in FIG. 14 (a), the right half of the user's body on one (right) dividing section 5 tries to move forward, and the other (left) dividing section. The left half above 5 tries to move backwards, which is the opposite. After that, since both the dividing sections 5 have the same period, as shown in FIG. 14B, when one (right) dividing section 5 moves backward, the other (left) dividing section 5 moves to the front. Move to. As a result, the right half of the body on one (right) dividing section 5 tries to move backward, and the left half of the body on the other (left) dividing section 5 tries to move forward. Thus, the user sitting on the seat 1 (shown by a broken line and a two-dot chain line) has a waist part 28 (shown by a two-dot chain line in FIG. 14) around the axis in the height direction of the upper body. It is possible to perform a swinging motion so as to alternately twist the front and rear. That is, by moving the pair of divided portions 5 in different directions, it is possible to perform an action of shaking the body.
The above-described rocking operation (first rocking operation) is a case where the periods of both the dividing sections 5 are the same but the phases are different (a state where they are not synchronized).

In the operation program shown in FIGS. 14A and 14B, when the reciprocating drive unit 7 is driven and the dividing units 5 are alternately moved back and forth, the rotation support unit 9 in FIG. Although 25 is a power transmission state, the rotation of the motor 12 is stopped. As a result, the base member 18 is in a fixed (restrained) state in which it cannot rotate with respect to the rotation base portion 10.
Alternatively, when the reciprocating drive unit 7 is driven and the dividing units 5 are alternately moving back and forth, the clutch 25 is in a free state in the rotation support unit 9 of FIG. 2, and the base member 18 is moved to the rotation base unit 10. It is good also as a state which can be freely rotated with respect to. In this case, the user sitting on the seat portion 1 swings the waist portion 28 (shown by a two-dot chain line in FIG. 14) alternately around the height axis of the upper body. Since the seat body 30 can freely rotate, the load on the waist can be reduced, and the user can perform weak exercise.

  Although not shown, in the first swinging operation, the periods of both the dividing sections 5 are the same. However, for example, the rotation speeds of the motors 19 may be made different to make the both periods different. That is, the movement and the movement of the treatment part may be performed by moving the divided parts 5 with different phases and cycles (second shaking action).

  FIG. 15 shows a case where another operation program is selected. In FIG. 15, when the reciprocating drive unit 7 is driven and the dividing unit 5 is operating back and forth alternately, in the rotation support unit 9 of FIG. 2, the clutch 25 is in a power transmission state and the motor 12 is driven to rotate. It is in a state of being. Further, the main control portion 58a for the seat portion 1 of the control device 8 periodically switches the rotation direction of the motor 12 of the rotation drive portion 12 in accordance with the reciprocation of the pair of division portions 5. That is, as shown in FIG. 15 (a), the rotation support unit 9 rotates the pair of divided units 5 counterclockwise from the initial state by a predetermined angle (90 ° or less) in plan view. The (right) dividing unit 5 is moved forward, and the other (left) dividing unit 5 is moved backward. Thereafter, as shown in FIG. 15B, one pair of the divided portions 5 is moved while rotating the pair of divided portions 5 clockwise by a predetermined angle (90 ° or less from the initial state) in plan view. Move backward, and move the other (left) dividing unit 5 forward. This operation is repeated.

  Accordingly, the user sitting on the seat portion 1 is forced to move the waist portion 28 (indicated by a two-dot chain line in FIG. 14) around the height axis of the upper body by the rotation drive portion 11. While twisting, the reciprocating drive unit 7 linearly moves the pair of divided parts 5 in the opposite directions so as to be in the same direction as the twisting direction, and can swing the waist part 28 so as to alternately twist. In this case, the load on the waist portion 28 can be increased compared to the case of FIG. 14, and the user can perform a strong exercise.

FIG. 16 shows a case where another operation program is selected. This operation program is a case in which a part (step) for reciprocating the pair of dividing units 5 in a synchronized state is included. For example, the rotation drive unit 11 rotates the pair of division parts 5 in the initial state by 90 °, and the longitudinal direction of the division part 5 is set as the left-right direction as shown in FIG. In this state, the reciprocating drive unit 7 starts the operation so that the pair of dividing units 5 move in the same direction and the phase is the same, and the reciprocating motion is continued in the same cycle as it is (FIGS. 16A and 16B). )). Thereby, in the seat part 1, a pair of division | segmentation part 5 performs the operation | movement which shakes a to-be-treated part by moving to the left-right direction. It is possible to give the user sitting on the seat portion 1 an operation of swinging the waist portion 28 back and forth in the left-right direction.
The above-described swaying operation (third swaying operation) is a case where the phases and periods of both the dividing sections 5 are the same (synchronized state).

  As another operation program, although not shown, a pair of divided parts in the initial state, that is, divided parts having the longitudinal direction as the front-rear direction, start reciprocal movement in the same direction, and have the same phase, as they are. There is a program that continues reciprocating motion in a synchronized state with the same period. Thereby, a pair of division | segmentation part 5 moves to the front-back direction, and the user who is seated on this division | segmentation part 5 becomes the operation | movement which reciprocates a waist | hip | lumbar part in the front-back direction. Moreover, it is good also as the diagonal direction inclined with respect to the front-back direction other than making the longitudinal direction of a division part into the left-right direction or the front-back direction. Further, as an operation program, there is one in which the rotation drive unit 11 operates in the middle of one operation program and changes the direction in which the dividing unit 5 swings.

  As described above, the operation selecting unit 8a of the control device 8 is reciprocated by the reciprocating drive unit 7 in a state where the pair of dividing units 5 are synchronized according to the operation program or in a state where the pair of dividing units 5 are not synchronized. It can be reciprocated by the reciprocating drive unit 7.

Furthermore, as described above, the air cell 14 is provided as a pressing portion in the seat portion 1 (dividing portion 5). The operation program includes a step of inflating the air cell 14 during execution of the massage operation. As a result, when the air cell 14 is inflated, each of the swinging motions (swinging motions) can include a motion in the height direction that pushes up the user (leg or upper body), and a more complex swinging motion. Can be given to the user. In particular, in FIG. 1, the air cell 14 provided on the side closer to the knee of the user's leg is inflated and the air cell 14 provided on the side far from the knee is contracted so that the knee side becomes higher. Tilts. Thereby, the seat part 1 can be regarded as being inclined. This action can include a stretching action on the leg. Moreover, the pressing position of the air cell 14 with respect to a to-be-treated part can be continuously changed by operating the division | segmentation part 5, expanding the air cell 14. As shown in FIG. Thereby, the air cell 14 can push the wide range of a to-be-treated part.
Further, as shown in FIG. 1, in the initial state, the air cell 14 is provided at the front portion and the rear portion of the seat body portion 30, but the pair of divided portions 5 are formed by the rotation support portion 9. Can be configured such that the air cell 14 is provided on the left side and the right side of the seat 1. In this way, the massage target part for the user's thigh or buttocks can be changed.

  Further, at the time of each swinging operation, for example, as shown in FIG. 14, the backrest part 2 may be in a state of sandwiching the upper body of the user from both the left and right sides. More specifically, the backrest 2 has protrusions 39 protruding forward (user side) on both left and right sides, and the upper body of the user is fitted between these protrusions 39. A massage tool is provided on each inner surface of the protrusion 39. This massage tool has an air cell 38, and the air cell 38 can be expanded and contracted by supplying and discharging air. The pair of left and right air cells 38 are installed apart from each other on the left and right, and can press the user (back side portion) so as to be sandwiched from both the left and right sides. Further, by sandwiching the user from both the left and right sides by the pair of air cells 38, the upper body of the user can be fixed so as not to move from side to side.

  FIG. 16 shows a modification of the backrest 2 of FIG. The backrest 2 is provided with massage tools corresponding to the left and right sides of the user's back. This massage device has an air cell 38 that expands and contracts by supplying and discharging air. The air cell 38 is provided along the height direction on both the left and right sides of the backrest 2. The pair of left and right air cells 38 are installed apart from each other on the left and right, and can be pressed so as to sandwich the upper body of the user from both the left and right sides. Further, by sandwiching the user from both the left and right sides by the pair of air cells 38, the upper body of the user can be fixed so as not to move from side to side.

14 and 16, the dividing portion 5 (55) can be moved as described above in a state where the upper body of the user is sandwiched between the pair of air cells 38 in the backrest portion 2. Thus, by moving the dividing portion 5 (55) in a state where the upper body of the user is fixed to the backrest portion 2, the user more strongly exercises the exercise of shaking the waist 28 (the exercise of shaking to twist). be able to.
Furthermore, you may operate other massage tools (for example, treatment unit 16) with the movement of the division part 5 (55). For example, the split part 5 (55) is reciprocated in order to make the waist part swing in the seat part 1, and the treatment unit 16 in the backrest part 2 (see FIG. 1) is attached to the upper body of the user by the treatment element 16a. You may give a massage (it massages, beats, rubs, kneads).

  Moreover, in FIG. 1, the leg mounting part 3 is provided with the some air cell 32 as a massage tool. These air cells 32 can be expanded and contracted by supplying and discharging air. The air cells 32 are arranged in pairs so as to face each other. The pair of air cells 32 can inflate the user's leg from both the left and right sides by expanding. These air cells 32 may sandwich the left and right legs of the user from the left and right sides to fix the legs to the leg rest 3 and move the dividing section 5 (55) as described above. Thereby, the user can perform the exercise | movement which shakes a waist | hip | lumbar part (exercise | rocking so that it may twist) more strongly.

  As mentioned above, according to each embodiment, the massage mechanism which seat part 1 has has a pair of division parts 5 (55), and main control part 58a for seat part 1 of control device 8 (refer to Drawing 24). ), The reciprocating drive unit 7 whose operation is controlled can reciprocate each of the dividing units 5 (55) independently. Therefore, the part which one division part 5 (55) supports among the user's bodies sitting on the seat part 1, and the part which another division part 5 (55) supports. In this case, it is possible to give a complicated movement in which the direction of shaking is different.

[Fifth Embodiment]
FIG. 17 is a plan view showing a fifth embodiment of the chair of the present invention. In each of the above embodiments, the case where the split portion 5 (55) is provided in the seat portion 1 has been described.

  And like each said embodiment, the leg mounting part 3 (it demonstrates with reference to FIG. 2 or FIG. 18 and FIG. 19), as a massage mechanism, the reciprocating base part 6, the reciprocating drive part 7, and rotation It has the support part 9 (the rotation base part 10 and the rotation drive part 11). The reciprocating base portion 6 is attached to each of the divided portions 35 so as to freely reciprocate. The reciprocating drive unit 7 can reciprocate each of the dividing units 35 (independently). The rotation support unit 9 allows the dividing unit 35 to rotate about an axis in a direction intersecting the support surface (around an axis along the length direction of the leg from the sole to the knee). And the main control part 58a (refer FIG. 24) for the leg mounting part of the control apparatus 8 controls operation | movement of the reciprocating drive part 7 and the rotation drive part 11. FIG. Thereby, the division part 35 can reciprocate. In addition, the operation | movement which shakes the to-be-treated part of a leg by reciprocating the other structure and these division | segmentation parts 35 is the same as that of each said embodiment.

  According to the chairs of the above embodiments, each of the divided portions can be moved in the body support such as the seat portion 1 and the leg rest portion 3, so that the operation of shaking the treatment portion is a complicated operation. be able to.

  In addition, the chair of the present invention is not limited to the illustrated form, and may have other forms within the scope of the present invention. In the above-described embodiment, the body support body that supports the user's body is the seat portion 1, and when the split portion 5 (55) is provided in the seat portion 1, the body support body is the leg rest portion 3, Although the case where the dividing part 35 is provided on the mounting part 3 has been described, although not shown in the drawings, a plurality of dividing parts may be provided on the backrest part 2 to shake the back part of the upper body of the user. .

When the left and right air cells are alternately expanded by the control of the control device 8, the user's body B can be alternately twisted so as to rotate around the spine.
The control device 8 moves the back rest 52, the buttocks rest 53, and the leg rest 54 in the left-right direction without synchronizing, and the pressing portion 77 presses the user's body B alternately left and right. Specifically, as indicated by the solid line arrows in FIG. 20, the backrest 52 and the leg rest 54 are moved to the left, the buttocks rest 53 is moved to the right, and each operation is stopped. As shown in FIG. 32 (b), the left pressing portion (air cell) 77 of the flange mounting portion 53 is expanded. After that, the back rest 52 and the leg rest 54 are moved to the right, the buttocks rest 53 is moved to the left, and the respective operations are stopped. Then, as shown in FIG. ) 77 is inflated. Thereby, the exercise | movement which bends a user's whole body to right and left can include the exercise | movement twisting centering on a spine, and a more effective stretch is attained.
Further, as shown by the solid line arrows in FIG. 20, when the back rest 52 and the leg rest 54 are moved to the left and the buttocks rest 53 is moved to the right, as shown in FIG. When the right pressing portion (air cell) 77 of the portion 53 is inflated, and then the back placing portion 52 and the leg placing portion 54 are moved to the right and the buttocks placing portion 53 is moved to the left, as shown in FIG. Thus, the right pressing part (air cell) 77 is expanded. This prevents the user's body (buttock) from being thrown out when reversing the left-right movement, and the exercise of lifting one side of the buttocks (moving direction) to the movement of bending the user's whole body to the left or right. In addition, a pendulum-like left-right movement can be realized. This makes it possible to stretch more comfortably on the body.

In the sixth, seventh, and eighth embodiments, the movement base unit 56 and the first drive unit A1 are not limited to the illustrated form, but may be of other forms. For example, in FIG. 23, the air cell 57b, which is the first drive unit A1, directly presses the buttocks mounting portion 53, but otherwise, the air cell 57b does not move the user's body B resting on the buttocks mounting portion 53. It may be configured to be pushed from the left and right (not shown). In addition, the moving base portion 56 of FIG. 28 supports the collar portion placing portion 53 by lifting it with the arm member 69, but otherwise, although not shown, the collar portion placing portion 53 is suspended by the arm. The structure which supports may be sufficient. FIG. 28 illustrates the case where the first driving unit A1 (the motor 70 and the like) is provided on each of the backrest 52, the buttocks rest 53, and the leg rest 54. In FIG. In the same manner as the left and right seat splitting sections 5 are operated by the driving section A1, the back mounting section 52, the buttocks mounting section 53 and the leg mounting section 54 are operated by the single first driving section A1.
