Further, the whole-body drive unit 7 is a mechanism for prompting the user at the user position A who is seated across the seat 8 to change the posture. A tilting operation for tilting the seating surface 8a forward, backward, left and right, accompanied by a minute movement, and a swinging and rotating operation based on a rolling operation in which the tilting operation is continued can be performed. In other words, the operation is performed so as to give the user a feeling as if the user is riding on the back of a horse.

  For the sake of convenience, the explanation will be made with the arrow X1 as the front, the arrow X2 as the rear, the arrow Y1 as the left, the arrow Y2 as the right, the arrow Z1 as the upper, and the arrow Z2 as the lower.

  Here, a pair of arm support portions 10 project from the left and right of the leg portion 9 and are adjacent to the left and right sides of the seat portion 8 and slightly higher than the seat surface 8a (specifically, the user's position A at the user position A). The upper surface of the upper arm forms an arm rest portion 5 on which a forearm can be mainly placed. In addition, the arm support unit 10 is provided with a grip part 2 that can be freely moved by a user. The arm support part 10 is also driven through the arm to the shoulder joint of the user who has gripped the grip part 2 by driving the grip part 2 to move. An arm drive unit 3 is provided for performing a typical inward and outward rotation motion. According to the arm drive unit 3, it is possible to cause the grip unit 2 to perform various types of movement drive, but in order to prevent unexpected movement on the user's shoulder, the grip An arm drive guide unit 4 that is a mechanism for restricting the unit 2 to a predetermined movement drive is also provided.

  A mechanism as shown in FIG. 2 can be employed as the arm drive guide unit 4 that causes the grip unit 2 to perform a predetermined movement drive by the arm drive unit 3. In this mechanism, the base end portion of the L-shaped movable member 11 which is bent upward and protrudes upward from the arm support portion 10 to constitute the grip portion 2 is used for rotation constituting the arm drive portion 3. It is a mechanism attached to an eccentric part of the rotary table 12 attached to the output shaft 13a projecting upward from the motor 13, and the rotation of the movable member 11 is moved to the grip portion 2 by a rotational drive of the rotary motor 13 in a substantially horizontal plane. This is a rotation drive mechanism that performs a movement drive that draws a rotation locus around the attachment portion 12a to the table 12. In the figure, reference numeral 14 denotes an auxiliary support portion for the movable member 11 to the rotary table 12. Here, the gripping portion 2 is provided by providing a feed mechanism of the movable member 11 to the attachment portion 12a of the movable member 11 to the rotary table 12, and changing the position in the length direction of the movable member 11 held by the attachment portion. The rotation radius of the rotation locus can be made different. Although not shown, the feed mechanism includes a slide motor that slides the holding portion of the movable member 11 on the attachment portion 12a in the length direction as the arm drive portion 3, and constitutes a slide drive mechanism. Also good.

  Further, a mechanism as shown in FIG. This mechanism includes a slide drive mechanism that causes the rod-like movable member 16 whose tip is protruded upward from the arm support portion 10 to become the grip portion 2 and a rotation drive mechanism that rotates the raising and lowering operation portion substantially horizontally. The grip portion 2 can be driven to move forward, backward, left and right. As the slide drive mechanism, the gear 17 attached to the output shaft 15a of the slide motor 15 constituting the arm drive unit 3 is engaged with the gear 18 provided integrally with the base end of the movable member 16, and the movable member 11 is engaged. A mechanism for driving up and down around the base end can be adopted, and as a rotation drive mechanism, a gear 20 engraved around a case 19 having a slide drive mechanism built therein is provided for rotation constituting the arm drive unit 3. A mechanism that meshes the gear 21 attached to the output shaft 13a of the motor 13 and rotates the entire rotational drive mechanism substantially horizontally can be employed.

  Further, a mechanism as shown in FIG. In this mechanism, an endless belt member 22 and a rail member 23 are disposed along the longitudinal direction of the arm support portion 10, and a rod-like movable member that protrudes upward from the arm support portion 10 to become the grip portion 2. The base member 24 is movably attached to the rail member 23 and fixed to the belt member 22, and the belt member 22 is rotated by the slide motor 15 constituting the arm drive unit 3, whereby the movable member 11 is moved. This is a slide drive mechanism that is driven along the rail member 23 so that the grip portion 2 can be slid in the longitudinal direction of the arm support portion 10. Although not shown here, the arm support portion 10 has a rod-like support portion 10 a that extends from the leg portion and supports the arm support portion 10, but has a rotation motor that constitutes the arm drive portion 3. And you may provide the rotation drive mechanism which rotates the arm support part 10 with respect to the support part 10a by the drive of a motor for rotation.

  Any of the arm drive guides 4 shown in FIGS. 2 to 4 can be used to drive the grip 2 to draw a rotation locus and a reciprocation locus. Specifically, the gripping unit 2 is controlled by the drive control of the slide motor 15 of the slide drive mechanism or the drive of the rotation motor 13 of the rotation drive mechanism by a drive control unit (not shown) provided in the passive motion apparatus 1. A movement operation combining a rotary movement operation and a reciprocating movement operation can be performed, and the movement range of the grip portion 2 can be made variable, so that variations of the movement applied to the shoulder joint can be increased.

  As described above, the passive motion apparatus 1 of the present invention has the grip portion 2 that is held by the user at the user position A, and the upper body of the user at the user position A. The arm drive unit 3 is arranged so as to be movable at the periphery of the arm and moves the grip unit 2 so as to cause the shoulder joint of the user holding the grip unit 2 to perform forced inward and outward movements via the arm. According to this, the grip part 2 in a state of being gripped by the user at the user position A is moved around the upper body of the user at the user position A by the arm drive part 3. By moving and moving relative to the user position A at the part, the user's shoulder joint can be forced to perform inward and outward movements via the arm, The user's shoulder joint can be effectively trained. Of course, since the movement to the shoulder joint of the user is performed through the arm, the elbow joint of the arm can be trained at the same time, and the adduction / extraction movement to be performed on the shoulder joint also involves expansion and contraction of the muscles around the shoulder The muscles around the shoulder can also be trained.

  Further, in the above-mentioned passive motion apparatus 1, the arm rest part 5 is provided together with the grip part 2, and the user puts the arm on the arm rest part 5 and holds the weight, and grabs the grip part 2 to shoulder joints. Therefore, it is possible to relax the user and effectively train the shoulder joint of the user who does not have strength.

  Further, the above-described passive motion apparatus 1 includes the user position forming unit 6 that forms the user position A, and the user position forming unit 6 that causes the user at the user position A to change the posture. Since the whole-body drive unit 7 for moving and driving is also provided, the user at the user position A can be moved and driven by the whole-body drive unit 7, that is, the relative movement of the grip portion 2 to the user position A In other words, since the synergistic effect of greatly changing and changing the movement of the user to the shoulder joint is obtained, there is also an advantage that the shoulder joint can be effectively trained.

  Further, the whole body drive unit 7 and the arm drive unit 3 in the above-described passive motion apparatus 1 are respectively driven and controlled by a control by a drive control unit (not shown) provided in the passive motion apparatus 1. 8 and the movement drive of the grip part 2 are performed. Here, in the above-described passive motion apparatus 1, a pair of grip portions 2 are provided on the left and right, but the left and right grip portions 2 are driven to move symmetrically (FIG. 5), or the left and right grip portions 2 are predetermined. The left and right grips 2 are driven to move in synchronization with each other, such as being moved and moved with the movement phase shifted (FIG. 6). Therefore, the user's shoulders can be trained at the same time or alternately with good rhythm, and the variation of shoulder joint training can be increased and the user can be expected to exercise with a predetermined rhythm. It is possible to relax the user and effectively train the shoulder joint of the user who has no strength.

  Further, for example, when the left and right grips 2 are positioned at different front and rear positions with respect to the user (for example, in FIG. 6, the user's right grip 2 is positioned forward and the left grip 2 is rearward). When positioned, the user's trunk can be twisted left and right, and the user can be twisted and stretched. In addition, when the left and right grips 2 are continuously slid backward and forward, the user holding the grip 2 can be given arm swinging motion during walking, and the walking rehabilitation effect and upper arm fat can be imparted. The diet effect by combustion can also be expected.

  Further, the quality of the movement may be changed by the left and right grips 2 (for example, in FIG. 7, the left grip 2 is moved back and forth and the right grip 2 is rotationally driven). According to this, the brain can be trained because the nerves are stimulated by different exercises on the left and right sides of the body.

  Further, in the above-described passive motion device 1, the mechanism shown in FIGS. 2 to 4 can be employed as the arm drive guide unit 4. However, any arm drive guide unit 4 can define a predetermined movement drive for the grip unit 2, so It is possible to cause the part 2 to repeatedly perform the expected movement drive, to relax the user and eliminate the force, and to effectively train the shoulder joint of the user without the force Also have.

  Here, the movement of the grip portion 2 by the cooperation of the arm drive portion 3 and the arm drive guide portion 4 is performed in a substantially horizontal plane (in a substantially vertical plane with respect to the upper body of the user), and the arms are raised and lowered. It has the advantage that the shoulder joints can be trained effortlessly by exercise with little burden on the shoulder.

  Further, a balance exercise device (device main body 1a) that shakes the whole body of the user seated on the seat 8 by the whole body drive unit 7 and trains the sense of balance of the user, such as the passive exercise device 1 of this example. In the apparatus equipped with the grip portion 2), when the grip portion 2 is driven to move in a substantially horizontal plane, the shoulder horizontal flexion and extension motion that encourages the back muscle group around the spinal column to stretch is performed. This is preferable because it can be forced and can relax the muscles of the back of the chest that are strained with force so as not to break the balance.

  Further, as a pattern of movement drive of the gripping part 2, the rotation radius of the rotation locus of the gripping part 2 is gradually increased by gradually increasing the distance from the rotation center of the gripping part 2 that is rotated by driving control of the slide motor 15. It is preferable that the reciprocal amplitude of the reciprocating locus of the grip portion 2 is gradually increased by controlling the driving of the slide motor 15, and according to this, the movement of the user's shoulder joint can be gradually increased. It is possible to relax the user and eliminate the force, and to effectively train the shoulder joint of the user without the force.

  In the above-described embodiment, the passive motion apparatus 1 including the grip portion 2 that performs a predetermined motion with respect to the seated apparatus main body 1a that changes the posture of the user who is seated on the seat portion 8 is changed. Although illustrated, it may replace with the said apparatus main body 1a, and you may employ | adopt the standing type or recumbent type passive-movement apparatus main body which makes a posture change to the whole body of the user who stood on the stand or slept. Further, the user's whole body of the user positioned at the user position A in a posture such as sitting, standing, and sleeping is not particularly subjected to any movement, and the user can grasp the user with the grip portion 2 disposed adjacent to the user position A. Even if the passive motion apparatus 1 is configured to perform only the motion of the shoulder joint, there is no synergistic effect by the whole-body drive unit 7 of the apparatus main body 1a of the above embodiment, but other advantages can be provided. Therefore, it is possible to effectively train the user's shoulder joint.
