The drive motor 13 is provided on the left side in the housing 5 so as to face vertically. Rotation drive shafts (first rotation drive shaft and second rotation drive shaft) protrude upward and downward from the upper end side and the lower end side of the drive motor 13 which is a biaxial motor, respectively. A first rotation drive shaft facing upward is connected to the first gear box 14.

A worm gear is attached to the tip of the first rotation drive shaft, and the worm gear meshes with a worm wheel 16 provided in the first gear box 14. A first rotating shaft 30 is inserted through the worm wheel 16 so as to face in the left-right direction. The first rotating shaft 30 is arranged so as to face in the left-right direction. As shown in FIG. 6, the first rotating shaft 30 is arranged on the right side of the housing 18 and the bearing 18 arranged in the first gear box 14 (the left bearing 18). The right bearing 18 is rotatably supported. The right bearing 18 is attached to an upper portion of a support body 28 (right support body 28) provided so as to project upward from a plate-like base body 27 disposed on the support leg 4. ing.

A conversion unit 15 that converts the rotational driving force into reciprocating oscillation and transmits it to the seat portion 3 is attached to a substantially central portion in the axial direction of the first rotation shaft 30.
As shown in FIGS. 2 and 6, the conversion unit 15 is attached to the first rotation shaft 30, and the first rotation boss portion 17 that rotates with the rotation of the first rotation shaft 30, and the first rotation boss portion. 17 includes a bearing 18 that fits on the outside of the bearing 17 and a first annular fitting portion 19 that fits on the outside of the bearing 18.

The first rotating boss portion 17 is disposed so as to rotate integrally with the substantially central portion in the axial direction of the first rotating shaft 30, and is a substantially circular and endless track inclined with respect to the first rotating shaft 30. (Cam surface). In addition, as shown in FIGS. 4 and 5, the first rotating boss portion 17 is provided so as to be eccentric with respect to the first rotating shaft 30, and deviates from the center of the first rotating boss portion 17. The first rotating shaft 30 passes through the position.

A bearing 18 (an inner race of the bearing 18) is fitted on the cam surface of the first rotating boss portion 17 so as to externally fit the cam surface.
On the other hand, the first annular fitting portion 19 is fitted on the outer periphery of the outer race of the bearing 18 so as to be fitted. The first annular fitting portion 19 is a through-hole penetrating in the left-right direction provided on the proximal end side of the seat connecting portion 20. In addition, the seat part connection part 20 is a member facing the up-down direction which connects the conversion part 15 and the seat part 3.

As shown in FIG. 6 and the like, the seat connecting portion 20 is a solid member having a T-shaped cross section, and the seat 3 is attached to the upper end of the seat connecting portion 20. The above-described first annular fitting portion 19 is formed at the lower end portion of the seat portion connecting portion 20 and is fitted into the first rotating boss portion 17 via the bearing 18. The first annular fitting portion 19 is an opening formed in a substantially annular shape in a side view at the lower end of the seat connecting portion 20. This opening is externally fitted to the outer peripheral surface (outer race outer peripheral surface) of the bearing 18 fitted into the cam surface. Therefore, the first rotating boss portion 17 and the first annular fitting portion 19 are rotatable relative to each other via the bearing 18.

The first annular fitting portion 19 converts the rotation of the first rotating boss portion 17 into a reciprocating swinging motion mainly in the left-right direction.
On the other hand, as shown in FIGS. 2, 5, 6, and the like, the front portion at the lower end of the seat connecting portion 20 is restricted from rotating together with the rotation of the first rotation shaft 30. The regulation part 21 for doing is arranged. The restricting portion 21 includes a hemispherical concave portion formed on the lower surface of the front portion of the seat connecting portion 20 and a ball body 22 that is slidably fitted into the concave portion. The ball body 22 is formed at an upper end portion of a crank body 23 described later.

Thus, since it is connected by the first joint portion (a hemispherical concave portion and the ball body 22 fitted therein) that can pivot, the movement of the vertical swing generated by the crank body 23 is as follows. The swinging motion generated by the conversion unit 15 is not hindered, and both swinging motions work in cooperation with each other, and the seat portion 3 is mixed with swinging up and down, left and right, and back and forth. Reciprocating motion will be developed.

Next, details of the second drive mechanism 12 that reciprocates the seat portion 3 mainly in the front-rear direction and the up-down direction will be described.
As shown in FIGS. 2, 3, 7, etc., the second drive mechanism 12 includes a drive motor 13 that outputs a rotational drive force, a second rotary drive shaft that projects downward from the lower end of the drive motor 13, A second gear box 25 that decelerates the rotational driving force transmitted by the second rotational driving shaft to a predetermined speed; and the reduced rotational driving force is converted into a reciprocating motion in the vertical direction; And a crank body 23 that transmits to the seat 3 connected thereto.

The second rotary drive shaft protruding downward from the lower end of the drive motor 13 has a worm gear attached to the tip, and the tip is inserted into a second gear box 25 arranged below the drive motor 13. A worm wheel 26 is disposed in the second gear box 25, and a second rotating shaft 31 facing in the left-right direction is provided on the worm wheel 26 so as to be integrally rotatable. The second rotating shaft 31 is rotatably supported via a bearing 18 provided in the second gear box 25.

As shown in FIG. 7, the right end portion of the second rotating shaft 31 protrudes rightward from the second gear box 25, and the right end thereof is attached to the support 28 via the bearing 18. . The rotational driving force of the second rotating shaft 31 is transmitted to the seat connecting part 20 by a crank body 23 described later, and the seat connecting part 20, that is, the front end of the seat 3 is swung in the vertical direction ( Crank mechanism).

The crank body 23 constituting the crank mechanism is composed of a long plate piece facing in the up-down direction.
Specifically, the second rotating shaft 31 is disposed so as to pass through the longitudinal base end portion (vertical lower end portion) of the crank body 23. A ball body 22 is attached to the upper end of the crank body 23 in the longitudinal direction (upper end in the vertical direction) so as to project upward.

As shown in FIG. 7, a second rotating boss portion 32 is disposed at a substantially central portion of the second rotating shaft 31 so as to rotate integrally with the second rotating shaft 31. The second rotating boss portion 32 is not inclined with respect to the second rotating shaft 31 and is provided so as to be eccentric with respect to the second rotating shaft 31, and deviates from the center of the second rotating boss portion 32. The second rotary shaft 31 penetrates through this position.
The second rotating boss portion 32 has a cam surface formed on the outer peripheral surface, and a bearing 18 (an inner race of the bearing 18) is fitted so as to externally fit the cam surface.

On the other hand, a ring-shaped second annular fitting portion 33 is fitted on the outer periphery of the outer race of the bearing 18. The second annular fitting portion 33 is fitted in a through-hole 34 penetrating in the left-right direction provided on the base end side of the crank body 23 in a loosely fitted state.
That is, the second annular fitting portion 33 is formed in a substantially annular shape in a side view at the lower end of the crank body 23, and a ring-shaped opening that is slightly larger than the size of the second rotating boss portion 32 is provided in the substantially central portion. It has been. This opening externally fits the outer peripheral surface (outer race outer peripheral surface) of the bearing 18 fitted in the cam surface of the second rotating boss portion 32. Therefore, the second rotating boss part 32 and the second annular fitting part 33 are rotatable relative to each other via the bearing 18. The second annular fitting portion 33 is connected to the base end side of the crank body 23 while being loosely fitted in the through hole 34 by the shaft body 35 (the shaft body 35 facing in the front-rear direction) on the lower side thereof. (Second joint portion, details will be described later).

On the other hand, a shaft body 36 facing upward is provided in a projecting manner at the upper end of the crank body 23, and the ball body 22 is attached to the tip (upper end) of the shaft body 36. . The ball body 22 is slidably fitted into a hemispherical concave portion formed at the front end of the lower end of the seat connecting portion 20.
Due to such a configuration, when the second rotating shaft 31 rotates, the second rotating boss portion 32 attached eccentrically rotates, and the crank body 23 reciprocates in the vertical direction and the front-rear direction. This vertical motion is transmitted to the seat connecting portion 20 via the ball body 22, and the rotation of the rotating boss portion that rotates together with the second rotation shaft 31 is converted into the vertical reciprocating swing motion of the front end of the seat portion 3. Will come to be.

When the crank body 23 reciprocally swings up and down, the lower end of the crank body 23 is moved in the left-right direction with respect to the second annular fitting portion 33 in order to make this swinging motion smooth. It is designed to swing. That is, the second annular fitting portion 33 is fitted in a loosely fitted state in a through hole 34 provided on the proximal end side of the crank body 23. In addition, the lower end portion of the crank body 23 and the second annular fitting portion 33 are connected by a shaft body 35 facing in the front-rear direction (second joint portion). Since the second joint portion is provided, the lower end portion of the crank body 23 is swingable in the left-right direction around the shaft body 35 facing in the front-rear direction, and the crank body 23 is connected to the second body via the shaft body 35. It can swing right and left with respect to the annular fitting portion 33.

Therefore, the rotation of the second rotating boss portion 32 that rotates together with the second rotating shaft 31 is smoothly converted into the reciprocating swinging motion of the front end of the seat portion 3 up and down and the swinging motion of the seat portion 3 in the left-right direction. There is no hindrance.
In other words, the crank body 23 can be said to be a connecting member that smoothly connects the first drive mechanism 10 and the second drive mechanism 12. The crank body 23 is connected to the first drive mechanism 10 and the second drive by a ball joint mechanism (first joint portion) arranged at the upper end and a swing mechanism (second joint portion) around the shaft body 35 at the lower end. When the mechanism 12 is interlocked, there is a function of smoothly connecting the swinging motion expressed by both the

mechanisms

10 and 12.

The operation mode of the riding exercise machine 1 having the above-described configuration is as follows.
The user M first sits in such a posture as to straddle the seat portion 3, and turns on the start switch using the operation panel portion 8.
Then, the drive motor 13 which is a biaxial motor provided in the swinging device 6 rotates and rotationally drives the first rotation drive shaft and the second rotation drive shaft. The rotational driving force transmitted to the first rotational driving force is transmitted to the first driving mechanism 10, and the seat portion 3 is mainly moved in the left-right direction by the action of the first rotating boss portion 17 and the first annular fitting portion 19. To reciprocating rocking motion.

That is, the rotational driving force transmitted from the drive motor 13 is transmitted to the first rotating shaft 30 via the first gear box 14, and the first rotating shaft 30 rotates the first rotating boss portion 17. This rotational driving force is transmitted to the first annular fitting portion 19, and coupled with the function of the restricting portion 21, mainly the movement in the left-right direction is taken out, and the seat connecting portion 20, that is, the seat portion 3 is swung back and forth mainly left and right. Let

Similarly, the rotational driving force transmitted to the second rotational driving force is transmitted to the second driving mechanism 12, and the second rotational boss portion 32, the second annular fitting portion 33, and the crank body 23 connected thereto are connected. By the action, the seat portion 3 is converted into a reciprocating swinging motion mainly in the vertical direction and the front-rear direction.
That is, the rotational driving force transmitted from the drive motor 13 is transmitted to the second rotating shaft 31 via the second gear box 25, and the second rotating shaft 31 rotates the second rotating boss portion 32. This rotational driving force is taken out as an eccentric motion in the front-rear direction and the vertical direction by the second annular fitting portion 33, and the crank body 23 reciprocates mainly in the vertical direction. Thereby, the front end of the seat part 3 becomes front rising or front falling.

For example, FIG. 4 shows a state in which the crank body 23 is pushed upward and the front end of the seat portion 3 is lifted forward. FIG. 5 shows a state in which the second rotating boss has rotated approximately half from this state. FIG. 5 shows a state where the crank body 23 is pushed downward and the front end of the seat portion 3 is lowered forward.
As described above, the seat portion 3 performs a motion combining the swing motion generated by the first drive mechanism 10 and the second drive mechanism 12. In the case of the present embodiment, the rotation speed of the first rotation shaft 30 and the rotation speed of the second rotation shaft 31 differ by a non-integer ratio (the number of gears of the worm wheel 16 of the first rotation shaft 30 (the number of gears = 40)). Since the number of gears of the worm wheel 26 of the second rotating shaft 31 (the number of gears = 58) is a non-integer ratio), the movement of the seat portion 3 in the left-right direction and the movement in the front-rear direction and the up-down direction are simple integer multiples. In other words, the seat portion 3 takes a very complicated movement (the movement trajectory becomes complicated). Therefore, it is possible to give the user a complicated balance exercise (exercise that gives a feeling of riding a horse).

Here, the non-integer ratio means that the ratio of the rotation speed of the first rotation shaft 30 to the rotation speed of the second rotation shaft 31 is an integer ratio such as “1: 8” or “2: 3”. Instead, the ratio includes decimal numbers such as “1: 9.23” and “2: 3.15”.
Such back-and-forth swinging and left-and-right swaying swing (pseudo-riding exercise) positively disrupts the balance of the user seated on the seat 3 and thereby the muscles of each part of the user's body. And the sense of balance can be strengthened, and as a result, health promotion such as dieting can be achieved.
[Second Embodiment]
Next, the riding exercise machine 1 according to the second embodiment will be described with reference to FIGS. 8 and 9.

As shown in FIG.8 and FIG.9, the boarding type exercise machine 1 of 2nd Embodiment is a seating type (chair type) used in the state which the user sat down.
Specifically, the seat portion 3 provided in the riding exercise machine 1 of the first embodiment is a horseshoe shape imitating the back of a horse (the center in the left-right direction is raised upward and the center in the front-rear direction is The seat portion 3 provided in the boarding exercise machine 1 of the second embodiment is lower in the center so that the user can sit down while sitting down. The chair is recessed toward the top.

That is, in the center of the seat portion 3 of the second embodiment, the seat portion 37 is provided so that the user who sits down can sit down. The seat portion 37 is a portion that has a saddle shape (a square shape with rounded corners) when viewed from above, and is formed of a seat having a cushioning property that can protect the flange portion.
An upper portion of the seat portion is provided with an enclosure portion 38 that surrounds the seat portion 37 and protrudes upward. The enclosure 38 is a backrest formed so that the protruding height increases upward from the front side toward the rear side, and the rear side on which the user leans compared to the front side through which the user passes when seated. It is high. By adopting such a configuration, the user's buttocks are prevented from falling from the seating portion, and the buttocks can easily enter the seating portion 37.

Further, a footrest portion 39 on which a user's foot is placed is formed on the lower front side of the seat portion. The footrest portion 39 is a curved rod-like member that is bridged so as to connect two points between the left front side and the right front side surface of the container 5, and the user's feet are placed on the upper side. It can be supported. If the enclosure part 38 and the footrest part 39 as described above are provided, the seat part 3 can be fastened with the knee as in the first embodiment, and the posture cannot be maintained (the boarding cannot be performed straddling). Even if it is a type exercise machine 1, since a buttocks can be fixed by the enclosure part 38 or a leg | foot movement can stop a leg | foot movement, it becomes easy to hold | maintain the posture during exercise | movement and exercise | moves in a safe environment. It becomes possible.

As shown in FIG. 9, the swinging device mounted on the riding exercise machine 1 of the second embodiment has a configuration substantially similar to that of the swinging device 1 of the first embodiment, and therefore will be described in detail. Is omitted (in FIG. 9, the same members as those in the first embodiment are given the same numbers as those in the first embodiment). The boarding exercise machine 1 of the second embodiment also includes a first drive mechanism 10 that reciprocally swings the seat portion 3 in at least the left-right direction, and a second drive that reciprocally swings the seat portion 3 in at least the vertical direction or the front-rear direction. And a mechanism 12.

In addition, it should be thought that embodiment disclosed this time is an illustration and restrictive at no points. In particular, in the embodiment disclosed this time, matters that are not explicitly disclosed, such as operating conditions and operating procedures, various parameters, dimensions, weights, volumes, and the like of a component deviate from a range that is normally performed by those skilled in the art. Instead, values that can be easily assumed by those skilled in the art are employed.

For example, the following configuration can be considered as a further modification of the riding exercise machine 1 according to the present embodiment.
Referring to FIG. 8 and the like, in the seat portion 3 of the second embodiment, the upper surface of the seat portion 37 is slightly lowered forward. This inclination makes it possible for the user to perform a more effective balance exercise (loading exercise on the body) because the user puts force on the abdominal muscles in order to avoid sliding down.

However, some users may feel anxious about the forward inclination of the seating portion 37 or actually slide down to the front side. On the other hand, other users may want to increase the forward inclination of the seating portion 37 to further increase the load on the body.
In response to such a requirement, it is preferable that the riding exercise machine 1 according to the present embodiment is provided with an inclination adjusting means for adjusting the front inclination of the upper surface of the seating portion 37.

As the inclination adjusting means, various forms are conceivable. As an example, a backrest cushion (cushion member) is conceivable.
As described above, from the left and right lateral sides to the rear side of the seating portion 37, the surrounding portion 38 that surrounds the seating portion 37 and protrudes upward is provided along the edge of the seating portion 37. The surrounding portion 38 is formed in such a manner that the upward projecting height increases from the front side toward the rear side (that is, an upward convex arc shape). A cushion member that is separate from the surrounding portion 38 is provided along the surrounding portion 38.

The cushion member has a shape along the enclosure portion 38 (particularly, the enclosure portion 38 corresponding to the user's back), the lower end is substantially horizontal, and the upper end is an arc “the moon of the first chord when the moon comes out”. It has a shape. Normally, the cushion member is leaned against an enclosure portion 38 corresponding to the rear portion of the seating portion 37, and the user can lean against the enclosure portion 38 with a soft feeling.
By pulling the lower end of the cushion member to the front side and tilting it so as to be stacked on the rear surface side of the upper surface of the seating portion 37, the upper surface rear side of the seating portion 37 is raised by the thickness of the cushion member 37. The front slope is larger.

In this state, the lower end of the cushion member is further pulled out to the front side, and the cushion member is stacked on the upper front side of the seating portion 37. Then, the front side of the seating portion 37 (corresponding to the lower part of the user's thigh seated) is raised by the thickness of the cushion member, and the front inclination of the seating portion 37 is relaxed, It is possible to prevent the user from sliding down to the front side.
