CM Operation module LM Leg module SM Sheet module 2 Sheet 6 Step

  Hereinafter, the present invention will be described based on an embodiment shown in the accompanying drawings. The exercise device shown in FIG. 1 shows a state in which a leg module LM and a seat module SM are assembled to an operation module CM. As shown in FIG. 2, the operation module CM includes a base plate 10, a support 4 rising from the front end of the base plate 10, and an operation panel 9 disposed on the upper end of the support 4. Handles 40, 40 protrude from the upper side of the left and right.

  The leg module LM has a pair of left and right steps 6 and 6 on its upper surface, and a step driving means 5 for driving the step 6 in its body. The step driving means 5 reciprocates and slides steps 6 and 6 in the front-rear and left-right directions, and changes the height positional relationship between the front end side and the rear end side of step 6 so that the user placed on step 6 The foot is caused to repeatedly perform a plantar flexion operation that lowers the toe side and a dorsi flexion operation that raises the toe side.

  An example of the step driving means 5 is shown in FIGS. Guide rails 51 and 51 are respectively fixed to the left and right upper surfaces of the base plate 50, and each guide rail 51 is provided with a slide block 52 having a slider portion slidable along the guide rail 51 at the bottom. Yes. A rotating shaft 53 is provided on the upper surface side of each slide block 52, and the plate-like step 6 is supported by the rotating shaft 53 so as to be rotatable around the axis of the rotating shaft 53. Further, a plate 66 biased upward by a spring 67 as shown in FIG.

  In these steps 6 and 6, one end (rear end) side and the base plate 50 are connected by a link 54. Note that universal joints 60 and 60 are provided at the connecting portion between one end of the link 54 and the base plate 50 and the connecting portion between the other end of the link 54 and the step 6, respectively.

  A drive motor 55 is installed between the left and right slide blocks 52, 52 on the base plate 50, a worm 56 is provided on the output shaft thereof, and a pair of worm wheels 57, 57 are attached to the worm 56. It is arranged on the left and right. The worm wheels 57 and 57 that mesh with the worm 56 have eccentric shafts 58 and 58, respectively. The eccentric shaft 58 is connected to the link 54 by a connecting rod 59. Note that the worm wheel 57 having the eccentric shaft 58 and the link 54 are located away from each other in the longitudinal direction of the guide rail 51, and a connecting portion between one end of the connecting rod 59 and the eccentric shaft 58 that connects the two and the connecting shaft. Universal joints 60 and 60 are also provided at the connecting portion between the other end of the rod 59 and the link 54.

  Now, when the eccentric shaft 58 is rotated by the motor 55 via the worm 56 and the worm wheel 57, the connecting rod 59 constituting the crank mechanism together with the eccentric shaft 58 is centered on the link 54 with the universal joint 60 on the base plate 50 side. Oscillating motion. Among the swinging motions, the slide blocks 52 and 52 and step 6 perform a reciprocating sliding motion in the direction along the guide rail 51 due to the movement of the component that coincides with the longitudinal direction of the guide rail 51.

  Further, due to the swinging movement of the link 54, the connecting portion between the link 54 and the step 6 also moves in the vertical direction, and accordingly, the step 6 also rotates around the rotation shaft 53. Step 6 becomes horizontal in the middle of the stroke of the slide operation, and the rear end side of Step 6 to which the link 54 is connected is lifted at one end of the stroke, and the rear end side of Step 6 is pulled down at the other end of the stroke. The eccentric shaft 58 and the link 54 are connected to each other by a connecting rod 59.

  For this purpose, the step 6 performs a sliding operation along the guide rail 2 and also performs a rotating operation in which the toe side is lowered when moving to the front side and the heel side is lowered when moving to the rear side.

  In the illustrated example, the left and right guide rails 51, 51 have an opening angle α so that when the slide block 52 and the step 6 move forward, they move so as to spread sideways. As is clear from FIG. 3, the rotation shaft 53 serving as the rotation center of step 6 is provided in a direction perpendicular to the longitudinal direction of step 6 and closer to the rear end than the longitudinal center of step 6. In addition, the axial direction of the rotary shaft 53 is not perpendicular to the longitudinal direction of the guide rail 51, and the front end side (toe side) of the step 6 is positioned in the direction swung inward from the guide rail 51. , 6 is wider in the front end side than in the rear end side, but the opening angle β is set in the range of 10 to 30 °.

  Note that the guide rails 51 and 51 may be arranged in parallel so that the steps 6 and 6 slide only in the front-rear direction and rotate only in the front-rear direction.

  Further, the left and right steps 6 and 6 are driven by the step drive means 5 when the position of the eccentric shaft 58 provided on the pair of worm wheels 57 and 57 meshing with the worm 56 is shifted and the step 6 on the right foot side advances. When the step 6 on the left foot side moves backward and the step 6 on the left foot side moves forward, the step 6 on the right foot side moves backward, that is, it operates so as to operate in opposite phases.

  The sheet module SM is composed of a cylindrical main body 11 that is long in the vertical direction, a sheet 2 disposed at the upper end of the main body 11, a drive unit 3 built in the upper part of the main body 11, and a flange 7. The drive unit 3 drives the seat 2 to swing back and forth and right and left.

  As shown in FIGS. 6 and 7, the drive unit 3 attached to the support frame 13 that moves up and down by the electric actuator 14 disposed in the main body unit 11 includes a motor in a box-shaped movable frame 30. 31 and a gear group 34 for transmitting the rotation of the motor 31 to the two output shafts 32 and 33, and the movable plate 8 disposed above the movable frame 30 is connected to the movable frame 30 by two types of links 41 and 42. The link 42 arranged at the front part of the movable frame 30 is connected at the lower end to the movable frame 30 by the shaft 421 and at the upper end to the movable plate 8 by the shaft 422, and is arranged at the rear part of the movable frame 30. The lower end of the link 41 is connected to the movable frame 30 by a shaft 411 and the upper end is connected to the movable plate 8 by a shaft 412.

  Further, the movable frame 30 is configured such that the bearing portions 300, 300 on the front and rear end faces thereof are connected to the top plate 131 provided at the upper end of the support frame 13 so as to be rotatable around the axis A shown in the drawing. Yes.

  The output shaft 32 of the two output shafts 32 and 33 that are rotationally driven includes an eccentric portion 320 positioned on the outer surface side of the movable frame 30, and the eccentric portion 320 is connected to the support frame by a link 35. 13 top plates 131.

  The other output shaft 33 also has an eccentric portion 330 positioned on the outer surface side of the movable frame 30, and this eccentric portion 330 is connected to the link 42 by a connecting link 36.

  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 reciprocate around the axis of the axis A.

  Further, the eccentric rotation of the eccentric portion 330 of the other output shaft 33 swings the movable plate 8 to the front end via the connecting link 36 and the link 42.

  Here, the seat 2 is fixed on the movable plate 8 which is driven to swing back and forth and right and left as the output shafts 32 and 33 rotate. 2 also swings back and forth and left and right, but 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. Further, when the drive unit 3 tilts to the left and right, the phase of the left-right swing and the front-back swing is set so that the movable plate 8 and the seat 2 swing forward.

  Here, the heel 7 disposed on the main body 11 is a bar-shaped member, and a right foot and a left foot can be placed on the left and right ends thereof. However, the heel 7 shown in FIG. 1 is in a state in which a user sitting on the seat 2 has retreated to a position that does not interfere with placing the foot on the step 6, and when the heel 7 is used, the heel 7 Is moved upward and set to the use position.

  The leg module LM and the seat module SM cannot be operated independently, and perform their functions when connected to the operation module CM. That is, the leg module LM is detachably attached to the upper surface of the front portion of the base plate 10 of the operation module CM, and the leg module LM is connected to the power supply unit and the control circuit C disposed in the operation module CM by being attached to the base plate 10. The motor 55 is connected. In addition, when the leg module LM is attached, the detection switch S1 disposed on the base plate 10 notifies the control circuit C that the leg module LM is attached.

  The seat module CM is detachably attached to the upper surface of the rear part of the base plate 10, and the motor 31 and the electric actuator 14 in the seat module CM are connected to the power supply unit and the control circuit C of the operation module CM by being attached to the base plate 10. Further, the fact that the seat module SM is attached by the detection switch S2 arranged on the base plate 10 is transmitted to the control circuit C.

  Here, in this exercise device, in the state where only the leg module LM is attached to the operation module CM, the state where only the seat module CM is attached, and the state where both the leg module LM and the seat module SM are attached, Different operation control is performed on the module LM and the sheet module LM.

  In a state where both the leg module LM and the seat module SM are attached to the operation module CM, the control circuit C turns off the motor 55 of the leg module LM and performs only the swing operation of the seat 2 of the seat module SM. Do.

  In this case, if the user sits on the seat 2 and puts the left and right feet in step 6 and turns on the start switch arranged on the operation panel 9, the control circuit C operates the drive unit 3 to operate the seat 2 Is swung back and forth and left and right. As described above, this swinging causes the seat 2 to tilt forward while the seat 2 tilts left and right. At this time, the user moves the legs by stepping on the plate 66 on the step 6 on the side where the seat 2 is inclined against the spring 67.

  On the other hand, when only the seat module SM is attached to the operation module CM, the user sits on the seat 2 and puts his / her foot on the heel 7 set at the use position, and operates the driving unit 3 in this state to remove the seat 2. Rock. It is possible to perform an exercise simulating horse riding. At this time, the user performs a movement that keeps a balance against shaking of the body from front to back and from side to side.

  Since the preferred swing speed of the seat 2 is different between the exercise performed with the foot placed on the step 6 and the exercise simulating riding, the control circuit C determines the rotational speed of the motor 31 of the seat module SM. Switching is performed according to the on / off states of S1 and S2. When performing any of the movements, the handle 40 provided on the support 4 may be grasped. Even users with poor balance function can use it with peace of mind.

  Next, when only the leg module LM is mounted on the operation module CM, the user stands with the left and right feet on the left and right steps 6 and 6 while holding the handle 40 and is placed on the operation panel 9. If the operation switch is turned on, the step driving means 5 gives the left and right steps 6 and 6 movements in the opposite phases to the left and right steps 6 and 6, and each step 6 is rotated so that the front end side is lowered during forward movement and the backward side is lowered during backward movement. Perform the action.

  For this reason, the user who puts his / her foot on Steps 6 and 6 moves his / her foot back and forth and right and left in accordance with the movement of Step 6, and also the plantar flexion and dorsiflexion of the ankle joint by the rotation of Step 6. Will be added. At this time, the plate 66 on the step 6 is integrated with the step 6 because the load due to the weight of the user standing on the step 6 is larger than the spring force of the spring 67 that biases the plate 66.

  By the way, as described above, the seat 2 is swung back and forth during one cycle of left and right swing, and when the drive unit 3 tilts left and right, the seat 2 moves forward. The phase of the left-right swing and the front-back swing is set so as to swing, but in setting the phase in this way, as shown in FIG. 12 (a), the movement of the seat 2 is viewed in plan view. In order to draw a figure 8, and to draw a substantially V shape as shown in FIG. 12 (b), the phase of back-and-forth swinging is shifted by 90 °. can do. In FIG. 12, the lower side is the front side as viewed from the user sitting on the seat 2.

  When only the seat module SM is mounted and exercise is performed with the foot placed on the heel 7, it is preferable that the seat 2 draws the trajectory shown in FIG. 12 (a). In addition to the seat module SM, the leg module LM also has the operation module CM. It is preferable that the seat 2 draws the trajectory shown in FIG. 12B when the user puts the foot on the step 6 and performs a stepping motion in accordance with the movement of the seat 2. Therefore, it is desirable that the swing locus of the seat 2 can be changed depending on which movement is performed.

  10 and 11 show an example in the case of corresponding to the change of the swing trajectory. An arc groove 335 is provided on the output shaft 33 in the drive unit 3 and screw holes 336 and 336 are formed at both ends of the arc groove 335. FIG. The eccentric shaft 330 is constituted by a screw 331 with a knob having a screw portion 332 at the tip thereof that is provided and inserted through the connecting link 36 and can be selectively screwed into the two screw holes 336 and 336. .

  Depending on which screw hole 336 is used to attach the output shaft 33 to the output shaft 33, the front-rear rocking phase can be changed by 90 ° with respect to the left-right rocking. It is possible to select which of the V-shaped trajectory and the V-shaped trajectory is performed on the sheet 2.

  In the above example, the swing trajectory is changed mechanically because the left / right swing and the front / rear swing operation are obtained from the rotation of the single motor 35. When the movement of the movement is performed by a separate motor, the above-described phase adjustment can be performed electrically, and a change in the movement locus can be easily handled. The swing locus can be changed by the output of the control circuit C according to the mounting state of the module LM.

  By the way, the mechanical structure for mounting the seat module SM and the leg module LM to the operation module CM may be any, for example, the base plate 10 of the operation module CM is shown in FIG. The left and right slide rails 100 and 100 are provided, and the leg module LM and the seat module SM are provided with a slide portion 101 that is slidably engaged with the slide rail 100, as shown in FIG. Further, instead of the slide portion 101, a rolling disc 102 whose outer periphery engages with the left and right slide rails 100, 100 is provided, or, as shown in FIG. 13 (c), rolling rolling on the slide rail 100. A wheel 103 may be provided. In these slide-type attachments, as shown in FIG. 13 (d), if the pinion 105 that meshes with the rack 104 provided along the slide rail 100 is provided in the leg module LM and the seat module SM, Position adjustment becomes easy. Reference numeral 106 in FIG. 13A denotes an end cap that closes the end opening of the slide rail 100, and is removed when the leg module LM and the seat module SM are attached or detached. In the case where either one of the leg module LM and the seat module SM is not attached, a gap is eliminated by mounting a dummy module (not shown) between the slide rails 100.

  In addition, as shown in FIG. 14, a protrusion 108 that fits into the recess 107 provided on the upper surface of the base plate 10 is provided on the lower surface of the leg module LM and the seat module SM, and a positioning hole provided on the inner wall of the recess 107. A spring-biased ball 110 that fits in 109 is disposed on the outer peripheral surface of the convex portion 108, and a pin 112 that protrudes from a lower surface of the leg module LM and the seat module SM in a hole 111 provided in the base plate 10. A drop-in type mounting structure such as a fitting or a protrusion 114 that fits in a groove 113 formed on the upper surface of the base plate 10 is provided on the lower surface of the leg module LM and the seat module SM can also be suitably used.

  Of course, the leg module LM and the seat module SM may be separately fixed to the operation module CM using bolts, or may be fixed magnetically using a magnet. In the drop-in type mounting structure, it is also preferable to use a separate fixing using a fixing member such as a bolt or a magnet.
