Among these, there is also an exercise device that allows simultaneous stepping exercise and waist twisting exercise (see, for example, Patent Document 1). The exercise device that allows the user to perform the stepping exercise and the waist twisting exercise at the same time uses the force of the stepping exercise, and the user reciprocates the pair of right and left footboards that the user rides in the left and right directions, thereby allowing the user to Twist exercise.

Patent Document 1: Japanese Utility Model Registration No. 3060544

It is pointed out that the exercise device used for the above-mentioned step exercise and the exercise device used for the waist twisting exercise are excessively large in exercise amount for the elderly and the woman for the purpose of dieting.

Therefore, it is conceivable that such an exercise device is provided with an electric motor, and the electric motor compensates for the angular force of stepping on the footboard to suppress the movement of the user. With an exercise device equipped with an electric motor, the user can exercise effectively by simply raising and lowering the foot naturally. In addition, since the burden on the user is small, it can be used continuously every day. For this reason, it becomes excellent compared with the exercise device of a manpower type.

However, in the exercise device described in Patent Literature 1, the left and right footboards have a structure of a cantilever support beam provided with a rocking support point portion on the front part side, and in this part not only the user's weight but also the answer during the foot motion. Input is supposed to work. For this reason, in the case where the exercise device is simply intended to be powered (driven by an electric motor), the electric motor driving the swing support point requires large driving torque and power, resulting in an increase in the size and cost of the exercise device itself. Done.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and in the state where the user's stepping force is supplemented with an electric motor, an exercise device that allows the user to simultaneously perform the step-in motion and the back-twist motion, does not cause the device to be enlarged and costly. It is aimed to provide without.

In order to achieve the above object, the present invention has taken the following means.

That is, the exercise apparatus according to the present invention has the left and right footboards disposed adjacent to each other and the swing support shafts provided on the front side of the left and right footboards so that the shaft center is in the left and right direction. A swinging mechanism for swinging up and down, a swinging mechanism for reciprocating the left and right footboards in a left and right direction with the pivot support shaft provided so that the shaft center faces the vertical direction, and the swinging mechanism and the swinging mechanism at the same time It has an electric motor to drive.

Thus, by setting the electric motor in the exercise device, the user who uses the exercise device can perform the step-in motion and the back-twist exercise simultaneously with the assistance of the electric motor, thereby enabling effective exercise. In addition, since the burden on the user is smaller than that of the manpower type exercise device, the advantage that it can be used continuously every day is obtained.

The swing mechanism has a mounting base plate and a movable base plate arranged parallel to the mounting base plate and movable around the pivot support shaft vertically provided on the mounting base plate. The right and left footboards, rocking mechanisms and electric motors may be provided.

The swinging mechanism includes a long hole formed in the rear and lower surfaces of the left and right footboards in the front-rear direction, an up-and-down driving shaft in which the shaft center is in the left-right direction, and fitted into the long hole, and the shaft center is in the left-right direction, and It is preferable to set it as the structure which has the rotation drive shaft with which the up-and-down drive shaft is attached in the eccentric state.

By doing in this way, the left and right footboards can be made into the both end part support structure by the above-mentioned rocking support shaft and an up-and-down drive shaft, and the structure can be strengthened. Further, the structure around the swing support shaft can be made simple.

Moreover, it is preferable that the said oscillation support shaft is provided in the cross shape with respect to the said rotation support shaft, and is able to pivot about the rotation support shaft in cooperation with the rotation of the movable base board to the left-right direction.

The swinging mechanism may be provided on the lower surface of the left and right footboards and may have a structure having an elastic member for pressing the footboard upwards.

By this elastic member, the footboard is always subjected to an upward pressing force, so that the user can change from the state of stepping on the footboard with a smaller force to the raised state. In addition, the burden on the electric motor is also reduced, so that a small electric motor can be adopted.

It is preferable to set it as the structure in which a single electric motor is arrange | positioned between the said left and right footboards, and a rotation drive shaft protrudes toward both left and right sides of the said single electric motor.

In addition, the swing mechanism may have a guide mechanism provided between the mounting base plate and the movable base plate to keep the gap between both base plates constant.

As a result, the swinging operation of the movable base plate becomes stable.

Moreover, the said turning mechanism has the power conversion mechanism which takes out the turning swing of a left-right direction from the up-and-down swinging of the stepping board | plate generated by the said swinging mechanism, and the said power conversion mechanism is between the left and right footboards and a mounting base board. It is good to set it as the structure installed in each.

Further, the power conversion mechanism is provided on an inclined cam disposed on an installation base plate and along an imaginary arc centered on a pivot support shaft, and on a lower surface of a left and right footboard, respectively, a sliding movement of sliding on an inclined surface of the inclined cam.

In addition, it is preferable that the inclined cam is formed with an inclined surface whose height increases as it is spaced apart from the pivot support shaft.

In this case, when either of the left and right footboards are moved to the low position, the footboard facing the low position turns toward the outside of the left and right swings. Therefore, the user riding on the footboard can move the weight stably without difficulty according to the natural sense.

In addition, the movable base plate has a pair of left and right cutouts cut at both ends thereof toward the center side of the movable base plate, and at the time of turning left of the movable base plate, the left answer is in the left cutout. It is very preferable that the inclination cam provided below the standing board is positioned, and the inclination cam provided below the right footboard is located in the right cutout at the time of right turn of the movable base plate.

By doing in this way, a movable base board can reliably turn to the installation base board to the left-right direction.

Moreover, what is necessary is just to set it as the structure which the rail member is provided in the lower surface of the said step board, and the rail member is provided with the long hole which faces the front-back direction.

Further, preferably, the left and right footboards are provided with a gripping rod that faces upward and is capable of being gripped by the user, and the gripping bar may be configured to swing back and forth in conjunction with the vertical swing of the footboard.

It is very preferable that the pivot support shaft of the swing mechanism is disposed so as to be positioned just below the user who rides in the posture on the left and right footboards.

In this way, the user who rides on the left and right footboards, for example, is given a turning around the spinal column of the body. Therefore, the user who is subjected to the swinging operation is in a situation where the user is urged to perform a stable waist twisting operation without causing the center of gravity movement that causes the spinal column to move horizontally. Therefore, there is an advantage that the exercise can be continued comfortably without breaking the posture (balance).

Moreover, the pivot support shaft of the said turning mechanism is arrange | positioned between the left and right footboards, and is located in the position corresponding to the substantially center of the front-back direction of the said footboard, or the pivot support shaft of the said swing mechanism is with respect to the installation base board. What is necessary is just to be arrange | positioned in the position corresponding to the substantially center of a front-back direction, and to the substantially center of a left-right direction.

The right cutout 20R is formed in a size and concave shape that can avoid contact with the power conversion mechanism 23R on the right side when the movable base plate 16 turns to the right side.

The swinging mechanism 10 is a rocking support shaft 27 which separately supports the left and right footboards 2L and 2R on their swing support points side, and on the up and down swinging sides in the left and right footboards 2L and 2R. A vertical drive shaft 28 circumferentially moving in the vertical plane with the shaft center in a left-right direction, and a rotation drive shaft 29 positioned at a locus center of circular movement of the vertical drive shaft 28 to rotate the vertical drive shaft 28 in a circle. Have

The swing support shaft 27 is disposed on the front side side on the movable base plate 16. As for the up-and-down drive shaft 28 and the rotation drive shaft 29, the swing support shaft 27 is arrange | positioned at the rear part side. The swing support shaft 27 is provided in a state shared by the left and right footboards 2L and 2R. On the other hand, the up-down drive shaft 28 and the rotation drive shaft 29 are provided in each depression board | plate 2L and 2R.

The swing support shaft 27 is supported at both ends between the brackets 32 provided on the outer side in the width direction of the left and right footboards 2L and 2R, respectively, and is temporarily supported at a predetermined height. The shaft cap 17 penetrates between an intermediate portion of the swing support shaft 27, that is, the left footboard 2L and the right footboard 2R. For this reason, when the part which penetrates the axial cap 17 is planarly viewed, the swing support shaft 27 and the pivot support shaft 15 of the swing mechanism 10 will have the arrangement which crossed.

Moreover, the cylindrical columnar passage part 33 is being fixed to the left and right footboards 2L and 2R on each lower surface. The pivot support shaft 27 penetrates through each of the shaft passage portions 33 in a rotatable state.

The rotary drive shaft 29 provided in the left footboard 2L is fitted with the middle footboard 2L coaxially arranged with each other in a state in which the left footboard 2L is fitted in the center and separated to face from both left and right sides thereof. It has an outer shaft 29b. The intermediate shaft 29a protrudes downward from the deceleration part 35 provided between the left and right depression boards 2L and 2R toward the lower side of the depression board 2L on the left side. The outer shaft 29b protrudes from the outer rotor 37 rotatably installed by the rotor bracket 36 from the outside beyond the left depression plate 2L toward the bottom of the left depression plate 2L.

The reduction unit 35 is fixed on the movable base plate 16 via the motor stand 40. The electric motor 12 mentioned above is connected to this deceleration part 35. The deceleration part 35 decelerates the drive rotation �� which is provided from the electric motor 12, and takes out the rotation as the rotation of the intermediate shaft 29a of the rotary drive shaft 29. The inner rotor 41 is provided in this intermediate shaft 29a in such a manner that they can rotate integrally with each other.

In addition, the outer rotor 37 is a disk body, is fitted into the circular recess formed concave in the rotor bracket 36 without any rattle and is rotatably held. The outer shaft 29b is provided so that the center of this outer rotor 37 and the center in the circular recess in the rotor bracket 36 may penetrate. The outer shaft 29b is rotatable relative to either or both of the outer rotor 37 or the rotor bracket 36.

The upper and lower drive shafts 28 provided on the left footboard 2L are sandwiched between the outer rotor 37 and the inner rotor 41. The up-and-down drive shaft 28 is connected to the outer rotor 37 and the inner rotor 41 at positions eccentrically facing each other from their center of rotation and by the same distance. That is, the rotation drive shaft 29 and the vertical drive shaft 28 are parallel to each other.

Therefore, by rotating the inner rotor 41 by the reduction unit 35 by the drive of the electric motor 12, the vertical drive shaft 28 moves as if drawing a circular orbit around the rotation drive shaft 29. Thereby, the outer rotor 37 follows the rotation.

The rail member 43 is provided in the lower surface of the depression board 2L, and the up-and-down drive shaft 28 penetrates the inside of the elongate hole 44 which penetrated left and right by this rail member 43. As shown in FIG. This long hole 44 is formed long in the front-back direction. Thereby, only the component which the up-and-down drive shaft 28 oscillates up and down among the movement traces when the up-and-down drive shaft 28 moves circumferentially can be taken out.

Moreover, the cam follower 45 is provided in the up-and-down drive shaft 28 in the state which passes the inside of the elongate hole 46 of the rail member 43 in the state which an axis movement is impossible. Thereby, the up-and-down drive shaft 28 is made to move smoothly and smoothly in the long hole 44. As shown in FIG.

The rotation drive shaft 29 and the up-and-down drive shaft 28 provided corresponding to the right footboard 2R are substantially the same as those provided corresponding to the left footboard 2L. Therefore, detailed description thereof is omitted here.

However, the vertical drive shaft 28 provided corresponding to the left footboard 2L and the vertical drive shaft 28 provided corresponding to the right footboard 2R are shifted by 180 ° from each other. Given.

Moreover, the elastic member (spring body) 48 which generate | occur | produces the pressing force to the upper side on the lower surface of each left and right recessed board 2L, 2R on the lower side of these recessed boards 2L, 2R is pressed. Is installed. Therefore, the driving force of the reverse orientation at the time of switching to the ascending state from stepping on each of the left and right footboards 2L and 2R is easily obtained.

As shown in Figs. 2 to 4, the power conversion mechanisms 23L and 23R serving as main elements of the swing mechanism 11 are inclined cams 50 provided on the mounting base plate 14 and left and right. It has the sliding member 51 provided separately in the depression board 2L, 2R.

The inclined cam 50 is arrange | positioned along the virtual circular arc (refer the code | symbol P in FIG. 8) on the plane drawn centering around the turning support shaft 15. As shown in FIG. The inclined surface formed on the upper surface of the inclined cam 50 is aligned along the virtual arc P, and the height increases as it approaches the center position (center in the left and right directions) of the mounting base plate 14.

The left side sliding member 51 is arrange | positioned at the front-end | tip of the stay (connected bar) 53 provided in the vertically descending shape from the left footboard 2L, and slides on the inclined surface of the left inclined cam 50. It is movable. Similarly, the sliding member 51 on the right side is provided downward by the stay 53 connected in a vertically descending shape from the right footboard 2R, and slides on the inclined surface of the right inclined cam 50. It is possible. Each of these sliding members 51 has a structure in which wheels, rollers, balls, and the like are held in a rolling motion.

In the left and right power conversion mechanisms 23L and 23R, the inclination of the inclined cam 50 and the inclination (inclined angle) of the inclined surface, the inclination of the stay 53 and the length in the vertical direction are determined by the following relationship. have.

That is, in 23 L of power conversion mechanisms on the left side, when 2 L of stepping boards rise by the swinging mechanism 10, the sliding member 51 will raise to the high position in the inclined cam 50, and will also answer. As the standing plate 2L is lowered by the swinging mechanism 10, the sliding member 51 is a positional relationship that operates to slide to the low position in the inclined cam 50. As shown in FIG. During this time, the sliding member 51 is always kept in contact with the inclined cam 50.

Similarly, in 23 R of power conversion mechanisms on the right side, when 2 R of the step plates rise by the swinging mechanism 10, the sliding member 51 will raise to the high position in the inclined cam 50, and also the answer As the standing plate 2R descends by the swinging mechanism 10, it is a positional relationship which operates so that the sliding member 51 may slide to the low position in the inclined cam 50. As shown in FIG. During this time, the sliding member 51 is always kept in contact with the inclined cam 50.

When the sliding member 51 slides the inclined surface of the inclined cam 50 from the high position to the low position, the reaction force pushed forward against the inclined cam 50 acts on the sliding member 51. This reaction force is transmitted to the movable base plate 16 through the left and right footboards 2L and 2R and the swinging mechanism 10. As a result, the movable base plate 16 is provided with a turning force in the left and right direction around the pivot support shaft 15.

The up-and-down swinging of the left and right footboards 2L and 2R by the swinging mechanism 10 alternates left and right since the vertical drive shaft 28 of each footboard 2L and 2R has a 180 ° phase difference. That is, in the turning mechanism 11, when the sliding member 51 rises to the high position of the inclined cam 50 in the left power conversion mechanism 23L, the sliding member 11 in the right power conversion mechanism 23R. 51 slides to the low position of the inclined cam 50. On the contrary, when the sliding member 51 rises to the high position of the inclined cam 50 in the right power conversion mechanism 23R, the sliding member 51 is inclined cam (in the left power conversion mechanism 23L). And slide to a lower position of 50).

As a result, as shown in Figs. 9 and 10, when the right footboard 2R is lowered (indicated by D in the figure), the movable base plate 16 turns to the right, and simultaneously with the left side The stepboard 2L is raised (indicated by U in the figure). On the contrary, when the left footboard 2L descends (D in the drawing), the movable base plate 16 turns left, and at the same time, the right footboard 2R rises (U in the drawing) ( Operation in the direction of the arrow Y shown in FIG. 1). By repeating this, the up-and-down fluctuations of the left and right rotations of the depression boards 2L and 2R and the reciprocating turning in the left-right direction of the movable base board 16 can be continued.

In this way, the swinging mechanism 10 and the swinging mechanism 11 are closely related to each other.

As is apparent from the above description, the exercise device 1 according to the present invention includes an electric motor 12, and the swing mechanism 10 is left and right recessed plates 2L, by the drive of the electric motor 12. 2R) is made to swing up and down alternately. Moreover, the swing mechanism 11 rotates the movable base plate 16 left and right by receiving the up-and-down swing of these left and right depression boards 2L and 2R.

Therefore, the user who rides on the left and right footboards 2L and 2R in the exercise device 1 has a depression motion (movement in the direction of the arrow X shown in Fig. 1) which causes the left and right feet to swing up and down, It is possible to simultaneously perform a waist twisting movement (movement in the direction of the arrow Y shown in Fig. 1) which alternately turns the waist from side to side. From this, the user can perform an exercise which is beneficial to the body, for example, aerobic exercise.

This coincides with the front, rear, left, and right directions based on the orientation of the user as shown in FIG.

The difference between the exercise device 1 of the second embodiment and the first embodiment lies in the swinging mechanism 10 and the swinging mechanism 11. The other configuration is about the same.

That is, the swing mechanism 11 includes a mounting base plate (fixed base plate) 14 mounted on the floor, and a pivot support shaft 15 provided with the shaft center on the mounting base plate 14 in the vertical direction. 15 and 18) and a movable base plate 16 provided so as to be able to pivot in the left and right direction about the pivot support shaft 15. As shown in FIG.

The pivot support shaft 15 is arrange | positioned in the position which becomes the position just below that with respect to the user who rides in a posture on the left and right footboards 2L and 2R. In addition, in 2nd Embodiment, the installation base board 14 was made into the circular plate, and the movable base board 16 was shown to make the long side side into the rectangular board which turned to the left-right direction in the range which fits on the installation base board 14. As shown in FIG. Doing.

The pivot support shaft 15 is disposed at its central portion with respect to the mounting base plate 14, and also at the position where the plate-shaped movable base plate 16 is approximately the center in the front-back direction and the center in the left-right direction. It is arrange | positioned (refer FIG. 15).

In addition, as shown in FIG. 18, the bearing 60 which externally fits in the state which can rotate the pivot support shaft 15 in the substantially center part of the installation base board 14 is provided. The pivot support shaft 15 is provided in the substantially center of the movable base board 16 in the state which protrudes downward. The pivot support shaft 15 is fitted into the bearing 60 from above. Therefore, the movable base plate 16 can be turned around the pivot support shaft 15.

Left and right footboards 2L and 2R, the swing mechanism 10 and the electric motor 12 are provided on the movable base plate 16. As a result, the movable base plate 16 is pivoted around the pivot support shaft 15, so that the left and right footboards 2L and 2R are held together in a state in which they are adjacent to each other. Turn from above.

Side wall bodies 61L and 61R are provided in the left and right side sides of the movable base plate 16. As shown in Fig. 13, wheels, rollers, balls, and the like are provided in the lower vicinity of the left side of the left side wall body 61L and the lower vicinity of the right side of the right side wall body 61R. The guide mechanism 18 held so that cloud movement is possible on 14 is provided.

Therefore, when the movable base plate 16 starts to incline about the pivot support shaft 15, the guide mechanism 18 which becomes the lower side of the inclination directly contacts the mounting base plate 14, Alternatively, the contact state is maintained from the beginning so that the movable base plate 16 does not tilt more than that. By such a guide mechanism 18, the movable base plate 16 is made to pivot stably from side to side in the state which maintained the space | interval of the up-down direction with the installation base board 14 substantially constant.

As shown in Figs. 13 to 17, the left power conversion mechanism 23L is provided between the right side of the left footboard 2L and the mounting base plate 14 on the rear side thereof, and the right side of the right footboard 2L. The power conversion mechanism 23R on the right side is provided between the left side portion of the depression board 2R and the mounting base plate 14 on the rear side thereof. These left and right power conversion mechanisms 23L and 23R are swing mechanisms 11 for extracting left and right swinging swing components from an operating component that swings the left and right footboards 2L and 2R up and down in the swinging mechanism 10. ) Is the main component of

Moreover, as the turning mechanism 11, it is enough only to provide at least one among the left and right power conversion mechanisms 23L and 23R. However, it is appropriate to have a configuration having both of the left and right power conversion mechanisms 23L and 23R in order to obtain smooth operation, robustness with little trouble, and the like. The details of these power conversion mechanisms 23L and 23R will be described later.

As shown in Fig. 16, the swing mechanism 10 includes a swing support shaft 27 for separately supporting the left and right footboards 2L and 2R at their swing support points, respectively, and each footboard 2L and 2R. A guide rail 65 mounted on the upper and lower swing sides (opposite to the swing support shaft 27) and facing forward and rearward, a slider 66 slidably coupled to the guide rail 65; Crank wheel 67 rotatably held by the slider 66 with the shaft center in the left and right directions, and a rotation input shaft 68 (rotation) provided with the shaft center in the eccentric position of the crank wheel 67 in the left and right directions (rotation). Drive shaft).

The swing support shaft 27 is disposed on the front side side on the movable base plate 16. The swing support shaft 27 supporting the left stepped plate 2L is the left side wall body 61L and the left side bearing on the movable base plate 16 on the right side of the left stepped plate 2L. It spans between 70 L of sieves. The left footboard 2L is swinging support shaft 27 by passing through the shaft support bracket 71 provided in the lower projecting shape on the left footboard 2L with respect to the intermediate part of this swing support shaft 27. It is kept in a state capable of swinging up and down as a circumference.

Similarly, the swing support shaft 27 that supports the right footboard 2R is a right side provided on the movable base plate 16 on the left side of the right side wall body 61R and the right footboard 2R. It spans between 70R of bearing bodies. By passing the shaft support bracket 71 provided in the lower projecting shape on the right footboard 2R with respect to the intermediate part of this swing support shaft 27, the right footboard 2R is the swing support shaft 27 It is kept in a state capable of swinging up and down as a circumference.

The guide rail 65 is a rail member 73 which is installed in parallel with each of the lower surfaces of the left and right footboards 2L and 2R, and faces the front and rear directions, and both ends of the rail member 73. It has a rail bracket 74 formed in an inverted c shape so that it can hold | maintain, and is fixed to the lower surface of each step board 2L, 2R through the back part of this rail bracket 74. As shown in FIG.

The slider 66 is a rail insertion passage 75 fitted in a skewer shape by the rail member 73 of the guide rail 65 and a circular ring-shaped wheel provided on the lower side of the rail insertion passage 75. It has a holder 76. With respect to the wheel holder 76, the crank wheel 67 formed in a disk shape can be rotated as it is in the axial direction in the lateral direction, and is maintained in a state not deviating in the lateral direction.

One end of the rotation input shaft 68 is rotatably held by a bearing portion 77 (see Fig. 13) provided on the left and right side wall bodies 61L and 61R. Similarly, the other end of the rotation input shaft 68 is connected with respect to the deceleration part 35 between left and right footboards 2L and 2R. This deceleration part 35 is fixed on the movable base plate 16 via the motor stand 40. The electric motor 12 mentioned above is connected to this deceleration part 35. When drive rotation is given from this electric motor 12, the deceleration part 35 decelerates the said rotation, and it transmits to the rotation input shaft 68 of both left and right, and rotates the said rotation input shaft 68. FIG.

The rotation input shaft 68 is provided in a state penetrating to the left and right sides at an eccentric position (a position shifted in the radial direction from the center of the disc shape) with respect to the crank wheel 67 and does not rotate relative to the crank wheel 67. It is fixed in the state (the state which rotates all). That is, when the rotation input shaft 68 is rotated, the crank wheel 67 is eccentrically rotated about the rotation input shaft 68.

At this time, the slider 66 eccentrically rotates around the rotation input shaft 68 together with the crank wheel 67. Here, since the rail insertion passage 75 of the slider 66 is inserted through the rail member 73, the relative slip between the circumference of the inner circumferential surface of the wheel holder 76 and the outer circumferential surface of the crank wheel 67 is reduced. Occurs. Thereby, the slider 66 is made to maintain the posture that the wheel holder 76 becomes lower from the rail insertion passage part 75 above.

As apparent from these, when the crank wheel 67 is eccentrically rotated through the reduction unit 35 and the rotation input shaft 68 by the drive of the electric motor 12, as shown in Figs. 19A to 19C, By the moving component of the front-back direction contained in this eccentric rotation, the slider 66 causes the rail insertion passage 75 to move along the rail member 73 of the guide rail 65. At the same time, the slider 66 causes the drive of the up and down oscillation with respect to the left and right footboards 2L and 2R by the up and down movement components included in the eccentric rotation of the crank wheel 67. In this way, the left and right footboards 2L and 2R swing up and down.

In the left and right footboards 2L and 2R, the eccentricity of the crank wheel 67 is in a positional relationship where phase shift occurs at 180 degrees (see Fig. 14). As a result, when the left footboard 2L descends, the right footboard 2R rises, and when the right footboard 2R descends, the left footboard 2L alternates up and down alternately. This is done.

In addition, as for the combination of the guide rail 65, the slider 66, and the crank wheel 67, two sets are provided in parallel with the left footboard 2L for the reason of the compactness and reinforcement of each member, and also the right side It is supposed that two sets will be added to 2R of step boards.

As shown in FIG. 14, FIG. 15, and FIG. 17, in the above-mentioned turning mechanism 11, 23 L of power conversion mechanisms on the left side are compared with the rocking support shaft 27 with respect to 2 L of left footboards. It has the connecting rod 82 on the left side in a rear position. The connecting rod 82 on the left side connects one end to the first universal joint 80 and the other end to the second universal joint 81 on the mounting base plate 14.

The 1st universal joint 80 which forms the connection part of the left depression board 2L and the left connection rod 82L is formed by the ball joint, for example. The first universal joint 80 has a spherical surface formed on the coupler component 83 provided in the state protruding to the right side with respect to the shaft support bracket 71 provided in the lower projecting shape on the left footboard 2L. The ball | bowl sheet and the ball part provided in the connection rod 82L are provided, and the fitting state by these spherical surface joining is formed.

Moreover, the ball joint can also be employ | adopted for the 2nd universal joint 81 which forms the connection part of the connection rod 82L of the left side, and the installation base board 14. FIG. The second universal joint 81 is formed on a spherical sheet formed in the hinge table 86 held in a state capable of swinging up and down with respect to the support base 85 provided on the mounting base plate 14, and the connecting rod 82L. The formed ball part is provided and the fitting state by these spherical surface joining is formed. That is, two spherical sheets are formed on both left and right sides of one hinge stand 86.

The same applies to the power conversion mechanism 23R on the right side, and the first universal joint 80 that forms the connecting portion between the right footboard 2R and the right connecting rod 82R is, for example, a ball joint. The spherical sheet formed in the coupler component 83 provided in the state which protruded to the left side, and the connection rod 82R with respect to the said axial support bracket 71 provided in the downwardly protruding shape on 2 R of right side boards. The ball part is provided and the fitting state by these spherical surface joining is formed.

Moreover, the ball joint can also be employ | adopted for the 2nd universal joint 81 which forms the connection part of the connection rod 82R of the right side, and the installation base board 14. FIG. The second universal joint 81 is provided with a spherical sheet formed on the hinge stand 86 held in a state capable of swinging up and down with respect to the support base 85 provided on the mounting base plate 14, and the connecting rod 82R. The formed ball part is provided and the fitting state by these spherical surface joining is formed. That is, two spherical sheets are formed on both left and right sides of one hinge stand 86.

The connecting rod 82L on the left side and the connecting rod 82R on the right side have a material and strength that do not stretch or bend deformation with an external force that is loaded when the left and right footboards 2L and 2R swing up and down. It is supposed to be. Accordingly, the distance generated between the first universal joint 80 and the second universal joint 81 as the left and right footboards 2L and 2R swing up and down with the swing support shaft 27 as a support point. The expansion and contraction change of the connecting rod 82L on the left side and the connecting rod 82R on the right side as it is, pushes and pulls the first universal joint 80 side (that is, the left and right footboards 2L and 2R) and the second. It is transmitted to the universal joint 81 side (namely, the installation base plate 14).

That is, for example, the vertical distance between the first universal joint 80 and the second universal joint 81 when the right footboard 2R is in an elevated state as shown in Fig. 21A is set to L, As shown in Fig. 21B, it is assumed that the stepboard 2R is lowered to a substantially horizontal state. The mutual distance at that time is shortened to L-α, as shown in Fig. 20B, and therefore, the connection rod 82R (length constant) on the right side is caused by the distance change α accompanying the falling of the depression 2R. The pushing force acts on the footboard 2R to move in the right direction. Further, the movable base plate 16 is pivoted right around the pivot support shaft 15.

As is apparent from Fig. 15, the connecting rod 82R on the right side is in a direction toward the outside inclined to the right in a plan view. For this reason, the pushing force does not act to move 2 R of the step boards to the right direction, and to push to the left direction.

Further, as shown in Fig. 21C, it is assumed that the E. plate 2R is lowered downward. The mutual distance at that time is shortened to L-β (β> α), and thus, a further pushing force acts on the connecting rod 82R on the right side due to the distance change β accompanying the lowering of the depression 2R. , The depression plate 2R moves in the right direction, and the movable base plate 16 pivots further right around the pivot support shaft 15.

On the contrary, as shown in Fig. 21C → Fig. 21B → Fig. 21A, when the right footboard 2R rises, the vertical distance between the first universal joint 80 and the second universal joint 81 is (L-β). ) → (L-α) → it becomes longer. For this reason, the pulling force resulting from this distance change acts, and the depression board 2R moves to the reverse direction, and the movable base board 16 turns left around the pivot support shaft 15. As shown in FIG. As such a pushing force and a pulling force act alternately, the movable base board 16 turns around the turning support shaft 15.

Similarly with respect to the left footboard 2L, the connecting rod 82L on the left has a constant length and is in a direction inclined to the left and directed outward when viewed in a plan view. For this reason, the pushing force resulting from the lowering of the left depression board 2L does not act to move the depression board 2L in the left direction and to push in the right direction.

As described above, in the left and right footboards 2L and 2R, the eccentricity of the crank wheel 67 is in a positional relationship where phase shift occurs at 180 degrees. As a result, when the left side board 2L descends, the right side board 2R rises, and when the right side board 2R descends, the left side board 2L alternates up and down. Is done. As a result, when the left footboard 2L descends and the pushing force acts on the connection rod 82L on the left side, the right footboard 2R rises and the pulling force acts on the connection rod 82R on the right side. do. On the contrary, when the right footboard 2R is lowered and the pushing force acts on the right connecting rod 82R, the left footboard 2L is raised and the pulling force acts on the left connecting rod 82L. .

Thus, when the left footboard 2L falls (DW in FIG. 20C), the movable base board 16 turns to the right, and at the same time, the right footboard 2R rises (in FIG. 20C). UP). When the right footboard 2R is lowered (indicated by DW in Fig. 20A), the movable base plate 16 turns left, and at the same time, the left footboard 2L is raised (UP in Fig. 20A). It is represented by). By repeating this, the left and right rotations of the left and right shifts with the pivot support shaft 27 of the footboards 2L and 2R as the support point and the left and right rotation pivoting around the pivot support shaft 15 of the movable base plate 16 are supported. You can continue to swing. In this way, the swinging mechanism 10 and the swinging mechanism 11 are closely related to each other.

Further, the base end of the non-elastic rope or the gripping rod made of metal or plastic may be inserted into the rope mount 93 described above so that the user can hold the upper end of the non-elastic rope or the gripping rod. good.

In the case where the gripping bar is adopted, the length of the gripping bar is about 1 m to 1.5 m, so that the user who has burned the upper end of the gripping bar on the footholds 2L and 2R can easily grasp it. It is preferable that the inclination angle of the gripping bar is an angle at which the gripping bar becomes substantially vertical when the footholds 2L and 2R are located at the lowermost side. For example, it is assumed that about 10 ° is tilted forward with respect to the upper surface of the footboard.

If such a gripping rod is provided, the user standing on the stepping plates 2L and 2R can simultaneously perform the stepping movement and the waist twisting movement under the assistance of the electric motor while holding the upper end of the gripping rod and in a stable state. . This allows the user to continue exercising without getting tired.
