  The present invention has been invented in view of the above-described problems, and allows the user's upper body to be moved by the device main body while swinging the user's upper body, and at the same time also efficiently with respect to the user's arm. It is an object of the present invention to provide a passive exercise device capable of applying exercise load and training muscles.

  In order to solve the above-mentioned problems, the apparatus for body movement B1 of the present invention causes the body movement B1 to perform a body movement while swinging at least the upper body of the user by an external action, and the side of the apparatus body B1. A grip portion B2 installed on the side, the grip portion B2 including a grip body 50 gripped by a user, a support body 51 that supports the grip body 50 movably within a predetermined range, and the grip It is assumed that it comprises a resistance applying mechanism 55 that gives resistance to the movement of the body 50 relative to the support body 51. By doing so, when the seat 2 is swung while being seated on the seat 2 and holding the grip body 50 of the grip B2, the movement of the seat 2 that causes the upper body of the user to swing is gripped. A user in a posture of gripping the body 50 is urged to move the grip body 50 with respect to the support body 51 within a predetermined range. By this action, when the support body 51 is moved against the resistance imparted by the resistance imparting mechanism 55, it is possible to exercise effectively by applying an exercise load to the deltoid muscle portion of the user's arm. In other words, according to the above-described passive motion device, in addition to the passive motion caused by the swing of the seat portion 2 of the device main body B1, the grip body 50 of the grip portion B2 is gripped and moved. Dynamic exercise can be performed at the same time, and it is possible to efficiently apply exercise load to the arm portion (particularly the deltoid muscle portion) of the user and train the muscle.

  Further, in the passive motion apparatus having the above-described configuration, the grip part B2 is installed on both the left and right sides of the apparatus main body B1, and the grip bodies 51 of the grip parts B2 on both sides are provided so as to be movable independently of each other. Is preferred. In this way, when the seat portion 2 swings in the diagonal directions of the front, rear, left and right along a trajectory such as a figure 8, for example, the left and right grip bodies 51 move independently. The left and right grip bodies 51 can be moved smoothly in cooperation with the swinging of the portion 2.

  The support body 51 preferably supports the grip body 50 slidably within a predetermined range. By doing in this way, the grip body 50 can be reciprocated along a stable track while the grip body 50 is stably supported by the support body 51 via an appropriate slide mechanism.

  In the invention according to claim 1, in addition to the passive motion caused by the swinging of the seat portion of the device main body, the passive motion of grasping and moving the grip body of the grip portion can be performed simultaneously. There is also an effect that it is possible to efficiently apply exercise load to the user's arm portion (particularly the deltoid muscle portion) and train the muscle.

  In addition to the effect of the invention according to claim 1, the invention according to claim 2 smoothly moves the left and right grip bodies even when the seat portion swings in the oblique direction of front, rear, left and right. There is an effect that becomes possible.

  In addition to the effect of the invention according to claim 1 or 2, the invention according to claim 3 reciprocates the grip body along a stable track while stably supporting the grip body on the support body. There is an effect that can be.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. In FIG. 1, the whole of the example of the passive exercise apparatus in the embodiment of the present invention is shown.

  The passive exercise apparatus of this example includes a seat portion 2 on which a user is seated, and swinging means for swinging the seat portion 2 three-dimensionally in the front-rear, left-right, and up-down directions. It comprises an apparatus main body B1 that performs a passive movement while swinging the seated user's upper body like riding, and grip sections B2 that are installed on both the left and right sides of the apparatus main body B1. In the illustrated example, the lower ends of the left and right grip portions B2 are connected in a U-shape with the bottom plate 4, and a separate device main body B1 is placed on the bottom plate 4 between the grip portions B2. However, the apparatus main body B1 and the grip B2 may be integrally formed. Hereinafter, the configuration of the apparatus main body B1 and the grip B2 will be described in detail.

  As shown in FIG. 3, the device main body B <b> 1 has a shape imitating the back of a horse and a saddle, and the upper surface is a seating surface, and swings the seat 2. It comprises an oscillating body 1 that houses a drive unit 3 that constitutes oscillating means. A reins 6 and an operation panel 8 are provided on the front end side of the seat portion 2, and hooks 7 are suspended from both front sides of the seat portion 2.

  As shown in FIG. 4, the oscillating body 1 includes a base frame 11 provided with grounding legs 15 at four corners, a support column 12 that rises obliquely rearward from a substantially central portion of the base frame 11, and the support column 12. A support frame 13 that is slidably mounted in the longitudinal direction of the support column 12 and an electric slide unit 14 that electrically slides the support frame 13. A base cover 16 that covers the upper surface of the base frame 11, and the support column 12. The outer surface is covered with a cover 17 covering the periphery of the main body 18, a main cover 18 covering the outer periphery of the support frame 13, and the like.

  On the other hand, as shown in FIG. 5, the seat portion 2 includes a seat frame 20, a seat surface 21 attached to the upper surface of the seat frame 20, a cover 22 connected to the lower side of the seat frame 20, A protective cover 23 to be attached, a panel cover 24 covering the periphery of the operation panel 8 and the like are configured. Further, the heel 7 includes a fixing piece 71 fixed to the heel attachment portion 200 on the side surface of the seat frame 20, a connecting piece 72 suspended from the fixing piece 71, and a footrest piece 70 suspended from the connecting piece 72. It consists of.

  As shown in FIGS. 6 to 9, the drive unit 3 includes a motor 31 and a gear group 34 that transmits the rotation of the motor 31 to the two output shafts 32 and 33 in a box-shaped movable frame 30. The movable plate 40 located above the movable frame 30 is connected to the movable frame 30 by two types of link plates 41 and 42. The movable frame 30 is attached to the oscillating body 1 by connecting the bearing portions 300 at the front and rear end surfaces thereof to the support frame 13 of the oscillating body 1 so as to be rotatable around an axis by a shaft 130 (see FIG. 4). It is done.

  Here, the link plate 41 connected to the rear end side of the movable plate 40 is connected to the side surface of the rear side of the movable frame 30 by the shaft 301, whereas the link plate 42 is connected to the movable frame 30. The shaft 303 is supported by the shaft 303 on the other end side of the rotating plate 39 that is disposed inside and supported by the movable frame 30 by the shaft 302. The link plate 42 is connected to the front end side of the movable plate 40 via an extendable actuator 45.

  The output shaft 32 of the two output shafts 32 and 33 that are rotationally driven has an eccentric portion positioned on the outer surface side of the movable frame 30, and this eccentric portion is connected to the support frame 13 by a link 35. The roll drive unit is configured.

  The other output shaft 33 has two eccentric portions 33a and 33b located on the outer surface side of the movable frame 30, and the eccentric portion 33a having a small eccentric amount is connected to the link plate 42 and has an eccentric portion having a large eccentric amount. 33b is connected to a connecting link 36 having one end connected to the link plate 41 to constitute a pitch driving unit.

  Of the two output shafts 32 and 33, the rotation of the eccentric portion of the output shaft 32 connected to the support frame 13 by the link 35 causes the movable frame 30 to rotate on the shaft 130 (the longitudinal axis A tilted back and forth in FIG. 8). ).

  Further, the eccentric rotation of the eccentric portion 33a of the other output shaft 33 swings the front end side of the movable plate 40 back and forth and up and down via the link plate 42 and the telescopic actuator 45, and the eccentric rotation of the eccentric portion 33b is connected to the connecting link 36. The rear end side of the movable plate 40 is mainly swung back and forth through the link plate 41. At this time, the trajectory of back and forth of the connecting shaft 40a between the link plate 41 and the movable plate 40 is T1, and the trajectory of back and forth of the connecting shaft 40b between the telescopic actuator 45 and the movable plate 40 is T2. As indicated by the arrows in FIG. 8, the strokes of both are the same, but the vertical component is set to be different between the trajectories T1 and T2.

  Incidentally, the trajectory T1 only moves substantially back and forth, but the trajectory T2 moves up and down in addition to the front and rear because the shaft 303 in the link plate 42 is located behind the shaft 40b. There are many ingredients. In addition, the rotating plate 39 is included in the components for swinging driving on the front end side of the movable plate 40, and the rotating plate 39 moves up and down the position of the shaft 303 serving as the rotating fulcrum of the link plate 42. The trajectory T2 takes a route that is shifted up and down between the outward path and the return path.

  Here, the seat 2 is configured such that the seat frame 20 is fixed on the movable plate 40 that is driven to swing back and forth and right and left as the output shafts 32 and 33 rotate. Although the seat 2 also swings back and forth and right and left together with the movable plate 40, the rotational speeds of the output shafts 32 and 33 are set so that back and forth swing is performed two cycles during one cycle of left and right swing. Therefore, the center point 21a, which is the center in the left-right direction and lowest in the front-rear direction on the seat surface 21 of the seat portion 2, is flat as shown in FIG. It looks like a trajectory as if the figure 8 was tilted sideways (in the left-right direction). Further, due to the difference between the trajectories T1 and T2, as shown in FIG. 10B, a trajectory is drawn in which the central point 21a sinks forward and returns to the rear while rising as shown in a side view.

  FIG. 10 is a plot of the movement of the center point of the seat 2 at a predetermined time interval. The speed is high when the point interval is large, and the acceleration changes when the point changes from a small interval to a large interval in a short time. It shows that it is big. That is, in the case shown in FIG. 10, the acceleration when moving forward is larger than the acceleration when moving backward. If this is a user who sits on the seat 2 and receives the movement of the seat 2, the user feels that he is moving forward. For this reason, he can get a sense of actually riding.

  Next, the grip part B2 will be described in detail. A pair of grip portions B2 disposed at positions sandwiching the device main body portion B2 from both the left and right sides, and a grip body 50 that a user holds and operates with one hand, and moves the grip body 50 within a predetermined range in the front-rear direction. It comprises a support body 51 that is freely supported, and a resistance applying mechanism 55 that provides resistance to the longitudinal movement of the grip body 50 relative to the support body 51.

  The support 51 is a plate-like member extending upward from the left and right end portions of the bottom plate 4, and the inner wall surface 51 a facing the device main body B 1 side has a rectangular shape in side view with the front-rear direction as the longitudinal direction. A slide hole 52 having a shape is opened. In the illustrated example, the slide hole 52 is penetrated to the outer wall surface 51b side, but may be formed in a concave groove shape on the inner wall surface 51a without penetrating.

  The grip body 50 includes a rod-shaped main body 53 whose axial direction is the left-right direction that is actually gripped by the user, and a rectangular slide integrally provided at the base end on the outer side in the left-right direction of the main body 53. Part 54. A slide portion 54 constituting the base end portion of the grip body 50 is fitted in a slide hole 52 of the support body 51 so as to be slidable back and forth. Note that the slide portion 54, that is, the grip body 50, is prevented from falling out of the slide hole 52 by a retaining means including a locking piece on the slide portion 54 side and a locking groove on the slide hole 52 side (not shown). .

  Further, in the slide hole 52, as the resistance applying mechanism 55, a front spring member 56 constructed between the front end surface of the slide portion 54 constituting the base end portion of the grip body 50 and the front inner surface of the slide hole 52. And a rear spring member 57 provided between the rear end surface of the slide portion 54 constituting the base end portion of the grip body 50 and the rear inner surface of the slide hole 52. In a reference state in which the user grips the main body 53 and does not apply an external force in the front-rear direction, the tension received from the pair of front and rear spring members 56, 57 is balanced, so that the grip body 50 is centered in the front-rear direction in the slide hole 52. Located in.

  Here, when the user grips the main body 53 and applies an external force forward, the tension received from the rear spring member 57 is greater than the tension received from the front spring member 56, and the grip body 50 has a backward drag. In addition, when the user grips the main body 53 and applies an external force to the rear, the tension received from the front spring member 56 is greater than the tension received from the rear spring member 57, and the grip body 50. Has a forward drag. Of course, the grip bodies 50 of the grip portions B2 on both sides can be moved in the front-rear direction independently of each other.

  Thus, in the above-described passive exercise apparatus including the central apparatus body B1 and the left and right grip sections B2 having the above-described configuration, the rider straddles on the seat surface 21 of the seat 2 of the apparatus body B1 like riding. While holding the grip body 50 of each grip part B2 with both left and right hands while driving, the drive part 3 is driven to draw a figure 8 in plan view on the seat part 2 as described above. By applying a trajectory that combines swinging back and forth, left and right, and up and down, such as sinking forward and returning to the back, the user is mainly given an exercise load like riding. You can train your abdominal, back, and thigh muscles.

  In addition, the movement of the seat portion 2 that swings the upper body of the user in the front-rear direction causes the grip body 50 to move relative to the support body 51 for a user who is gripping the grip body 50 of the grip portion B2. Work to reciprocate back and forth. By this action, when the support body 51 is moved back and forth against the drag force of the spring members 56 and 57, it is possible to effectively train the user's arms, particularly the deltoid muscles, by applying an exercise load. Yes.

  In this example, the moving direction of the grip body 51 is defined in the front-rear direction, but the moving direction is not limited to this, and the direction further tilted from the front-rear direction to the left and right, the up-down direction, the left-right, the up-down direction, etc. Other directions may be used. In addition, the grip body 51 is not limited to a structure that reciprocates on a straight line, but may have a structure that reciprocates on a curve, or may move freely within a fixed range of two or three dimensions. It is good also as a possible structure. The resistance applying mechanism 55 in this example uses the restoring force of the spring members 56 and 57 as resistance, but other means such as frictional resistance and viscous resistance may be used.

  In addition, as described above, in the present example, the device main body B1 of the passive exercise device is configured to load the user with exercise simulating riding, but the form of the device main body B1 is also limited to this. The present invention is not limited to this, and can be applied as long as it allows the user to perform a passive movement while swinging at least the upper body of the user by a physical action from the outside.

  That is, for example, as in the other passive exercise equipment schematically shown in FIGS. 11 and 12, the apparatus main body B <b> 1 is swung with the seat 2 on which the user is seated and each leg of the user is individually Even if it is a case where it is a case where it is a thing of the structure which loads the exercise | movement imitating walking motion to a user by moving the footrest base 60 mounted on the same, it is the same grip part B2 to the side of this apparatus main body part B1. The same effect can be obtained by installing the unit integrally or separately.

  The apparatus main body B1 of this other example includes a seat 2 that supports the user's buttocks while the sole is placed on a prescribed footrest surface 60a formed on the footrest 60 by the user, A drive part 3 that swings the seat part 2 back and forth and left and right so that its own weight acting on the leg part of the person changes, and a sole on the seat part 2 at the reference position, and the sole of the foot resting surface 60a at a specified position And an elevating mechanism 61 that adjusts the vertical and longitudinal positions of the seat 2 so that the bending angle θ of the knee of the user in a state where the user is placed is a specified angle.

  When the seat portion 2 moves forward from the rear end position within the swing range, the drive portion 3 is configured to alternately form a period of moving diagonally right forward and a period of moving diagonally left forward. 2 is driven to swing. As a result, it is possible to apply the own weight to the thighs of the left and right legs without applying a shearing force to the knee joint.

  A grip portion B2 similar to that of the example is installed on both sides of the device body portion B1 of this other example, and the above-mentioned other movement is performed while sitting on the seat portion 2 and holding the grip body 50 of the grip portion B2. Do exercise. At this time, as in the case of the example, for the user in a posture in which the movement of the seat portion 2 that swings the upper body of the user in the front-rear direction grips the grip body 50 of the grip portion B2, the grip body 50 is provided. Is urged to reciprocate in the front-rear direction with respect to the support 51. By this approach, when the support body 51 is moved back and forth against the drag, it can be effectively trained by applying an exercise load to the deltoid muscle portion of the user's arm.
