In the example shown in FIG. 4, the sliding surface S of the sliding course C is composed of a snow surface. In other words, the skiing course C is a snow course.

The start area RG1 is an area where the user starts the skiing course C. In the start region RG1, the user grasps the exercise assist device 4.

In the example shown in FIG. 4, the start region RG1 is a flat surface (in other words, a substantially horizontal surface). When the start area RG1 is a flat surface, a user who is performing preparatory work in the start area RG1 is prevented from unintentionally starting to ski.

The upstream part of the course CA is arranged between the start area RG1 and the jumping hill J. The upstream portion of the course CA has a first slope 11 (more specifically, a first slope snow surface 11a) whose height decreases toward the jumping hill J. The first inclined surface 11 constitutes an approach portion AP toward the jumping hill J.

The jumping hill J includes a transition portion J1 and a lip portion J2. The transition portion J1 is a portion between the approach portion AP and the lip portion J2. The transition portion J1 has an arcuate surface (for example, an arcuate snow surface) when viewed from the side. A part of the transition portion J1 may be a flat surface when viewed from the side. The lip portion J2 is a portion where the user jumps into the air from the jumping platform J. In the example shown in FIG. 4, the lip portion J2 is located at the tip of the transition portion J1.

The downstream part CB of the course is arranged downstream of the jumping hill J in the skiing direction. The downstream portion of the course CB may include a second slope 14 (more specifically, a second slope snow surface 14a) whose height decreases as it moves away from the jumping hill J. Further, the angle of inclination of the second inclined surface 14 may be the same as the angle of inclination of the first inclined surface 11, or may be smaller than the angle of inclination of the first inclined surface 11.

The downstream part CB of the course includes a landing area RG3. In this specification, "landing area RG3" means an area where the user who has jumped from the jumping hill J performs a landing motion. When a user who jumps from a jumping hill J lands on a ski course C, the landing area RG3 means an area where the user actually lands on the ski course C. On the other hand, when the user jumping from the jumping hill J is maintained in a floating state by the exercise assist device 4 without landing on the sliding course C, the landing area RG3 is the area where the user virtually performs the landing motion. means.

The departure region RG5 is arranged downstream in the sliding direction from the downstream course portion CB. The withdrawal region RG5 is a region from which the user withdraws from the exercise assist device 4. In other words, the user leaves the exercise assist device 4 in the withdrawal area RG5. In the example shown in FIG. 4, the departure area RG5 constitutes the end area of the skiing course C.

More specifically, the drive device 30 decelerates the moving body 24 that supports the exercise assist device 4 so that the exercise assist device 4 is decelerated relative to the sliding course C in the deceleration region RG4.

By decelerating the exercise assist device 4 in the deceleration region RG4, the user can safely leave the exercise assist device 4 in the withdrawal region RG5 downstream from the deceleration region RG4. For example, by decelerating the exercise assist device 4, the user can safely stop in the withdrawal area RG5, and then the user can safely leave the exercise assist device 4.

The moving body 24 may be decelerated by decelerating the endless member 21 of the conveyor 2. In this case, the conveyor 2 includes a control device 28 (see FIG. 1 if necessary) that controls the acceleration of the endless member 21, and the drive device 30 operates the endless member 21 based on a control command from the control device 28. The member 21 may be decelerated. Alternatively, as the deceleration mechanism for the moving body 24, a mechanism similar to the mechanism in which a lift system at a ski resort decelerates a seat when a user gets on and off may be adopted.

(Height adjustment of rotation auxiliary member 40)
In the example shown in FIG. 12, the height of the rotation assisting member 40 (for example, the rotation assisting bar 41) in the start region RG1 of the sliding course C can be adjusted according to the user's height. More specifically, in the example shown in FIG. 12, in the start region RG1 of the ski course C, the rotation assisting member 40 (for example, rotation The height of the auxiliary bar 41) can be adjusted.

If the height of the rotation auxiliary member 40 is adjustable in the start area RG1 of the skiing course C, the height of the rotation auxiliary member 40 with respect to the start skiing surface S1 can be changed in accordance with the user's height, etc. . Therefore, the somersault motion assist system 1A can suitably assist a somersault motion of a user of any height.

In the example shown in FIG. 12, the exercise assist device 4 (more specifically, the support member 50) includes a height adjustment member 91 for changing the height of the rotation assist bar 41. Alternatively, the moving member 20 (more specifically, the moving body 24) of the conveyor 2 may include a height adjusting member 91 for changing the height of the rotation assisting bar 41.

The height adjustment member 91 may include a first member 92a and a second member 92b whose position can be changed in the vertical direction with respect to the first member 92a. In the example shown in FIG. 12, the first member 92a is connected to the base portion 59 of the support member 50, and the second member 92b is connected to the rotation assisting member 40 (for example, the rotation assisting bar 41).

The height adjusting member 91 for changing the height of the rotation auxiliary member 40 may include an actuator (hereinafter referred to as "first actuator 92") for changing the height of the rotation auxiliary member 40. good. In the example shown in FIG. 12, the first member 92a of the first actuator 92 is a cylinder, and the second member 92b of the first actuator 92 is a rod. Alternatively, the first member 92a of the first actuator 92 may be a threaded rod, and the second member 92b of the first actuator 92 may be a nut member that is threaded onto the threaded rod.

The height of the rotation auxiliary member 40 (more specifically, the rotation auxiliary bar 41) in the start region RG1 can be adjusted by operating the first operation section 93 disposed at or near the start region RG1. It may also be done. In other words, even if the somersault movement assist system 1A includes the first operating section 93 and the first actuator 92 that adjusts the height of the rotation assisting member 40 by operating the first operating section 93. good.

In the example shown in FIG. 12(a), when the first operation section 93 is operated in the first operation MR1, the first actuator 92 moves to the height of the rotation assisting member 40 (more specifically, the rotation assisting bar 41). make it higher. On the other hand, in the example shown in FIG. 12(b), when the first operation part 93 is operated in the second operation MR2, the first actuator 92 moves the rotation assisting member 40 (more specifically, the rotation assisting bar 41). Reduce height.

The first operation unit 93 and the first actuator 92 may be configured to be able to communicate wirelessly. Further, the somersault motion assist system 1A may include a first battery 94 that supplies power to the first actuator 92.

(assist rate)
In this specification, the ratio of the force with which the exercise assist device 4 supports the user to the entire gravitational force acting on the user is defined as the assist ratio. In other words, the "assist rate" means the ratio of the supporting force acting on the user from the exercise assist device 4 to the supporting force acting on the user from both the sliding surface S and the exercise assist device 4.

In the example shown in FIG. 13, the assist rate in the landing area RG3 is higher than the assist rate in the upstream part of the course CA. In other words, the height H1 of the rotation assisting member 40 (more specifically, the rotation assisting bar 41) from the running surface S in the landing area RG3 is greater than the height H1 of the rotation assisting member 40 (more specifically, the rotation assisting bar 41) from the running surface S in the upstream part of the course CA. More specifically, it is higher than the height H2 of the rotation assisting bar 41). Note that, as illustrated in FIG. 13, each of "height H1" and "height H2" is a vertical line passing through the lower end of the rotation assisting member 40 (more specifically, the rotation assisting bar 41) and sliding. It means the distance between the intersection with the surface S and the lower end of the rotation assisting member 40 (more specifically, the rotation assisting bar 41).

Since the assist rate in the upstream part of the course CA is relatively low, the user can apply his or her weight to the sliding surface S, and can experience a more natural approach motion to the jumping hill J. Further, since the assist rate in the landing region RG3 is relatively high, even if the landing operation is inappropriate, the impact received by the user from the sliding surface S can be reduced.

In the example shown in FIG. 14, the assist rate in the departure area RG5 is lower than the assist rate in the landing area RG3. In other words, the height H3 of the rotation assisting member 40 (more specifically, the rotation assisting bar 41) from the running surface S in the departure area RG5 is greater than the height H3 of the rotation assisting member 40 (more specifically, the rotation assisting bar 41) from the running surface S in the landing area RG3. Specifically, it is lower than the height H1 of the rotation assisting bar 41). Note that, as illustrated in FIG. 14, each of "height H1" and "height H3" is a vertical line passing through the lower end of the rotation assisting member 40 (more specifically, the rotation assisting bar 41) and sliding. It means the distance between the intersection with the surface S and the lower end of the rotation assisting member 40 (more specifically, the rotation assisting bar 41).

Since the assist rate in the withdrawal area RG5 is relatively low, the user can apply his/her own weight to the ground or snow surface in the withdrawal area RG5, and the user can receive the assistance from the exercise assist device 4 in the withdrawal area RG5. You can easily leave.

(Assist rate adjustment mechanism M)
In the example shown in FIG. 15, the somersault movement assist system 1A has an assist rate adjustment mechanism M. More specifically, the somersault motion assist system 1A changes the height H4 of the rotation assisting member 40 from the running surface S at a position facing the start region RG1 (more specifically, the start running surface S1). Instead, it has an assist rate adjustment mechanism M that adjusts the height H1 of the rotation assisting member 40 from the sliding surface S in the landing area RG3. Note that, as illustrated in FIG. 15, each of "height H1" and "height H4" is a vertical line passing through the lower end of the rotation assisting member 40 (more specifically, the rotation assisting bar 41) and sliding. It means the distance between the intersection with the surface S and the lower end of the rotation assisting member 40 (more specifically, the rotation assisting bar 41).

The assist rate adjustment mechanism M may be able to adjust the assist rate in the landing region RG3 between 0% and 100%. When the assist rate is "0%", when the user jumps from the jumping hill J and lands on the landing area RG3, the rotation assisting member 40 does not substantially support the user's weight. On the other hand, when the assist rate is "100%", the rotation assisting member 40 supports the entire weight of the user. In other words, when the assist rate is "100%", the user who jumps from the jumping hill J does not land on the sliding course C in the landing area RG3, and the user is maintained in a floating state by the exercise assist device 4.

When the somersault motion assist system 1A includes the assist rate adjustment mechanism M, the assist rate can be adjusted according to the user's skill. For example, if the user's skill is relatively high, the assist rate may be set low, and if the user's skill is relatively low, the assist rate may be set high.

In the example shown in FIG. 15, the assist rate adjustment mechanism M includes an actuator (hereinafter referred to as a "second actuator") that moves the movement trajectory OB'' of the moving member 20 in the vertical direction at a position facing the landing area RG3 in a side view. 96''). In the example shown in FIG. 15, the conveyor 2 includes an auxiliary guide body 38 that guides the movement of the moving member 20 (more specifically, the endless member 21) at a position facing the landing area RG3 in a side view. have

In the example shown in FIG. 15, the second actuator 96 moves the movement trajectory OB'' of the moving member 20 (more specifically, the endless member 21) in the vertical direction by moving the auxiliary guide body 38 in the vertical direction. move it to

The assist rate may be adjusted by operating the second operating section 97 arranged in or near the start region RG1. In other words, the somersault motion assist system 1A may include the second operating section 97 and the second actuator 96 that adjusts the assist rate by operating the second operating section 97.

In the example shown in FIG. 15(a), when the second operation section 97 performs the third operation MR3, the second actuator 96 increases the assist rate in the landing region RG3. For example, when the second operation part 97 is operated in the third operation MR3, the second actuator 96 increases the height of the rotation assisting member 40 (more specifically, the rotation assisting bar 41) from the sliding surface S in the landing area RG3. is increased from the first height H1' (see FIG. 15(b)) to the second height H1 (see FIG. 15(a)).

On the other hand, in the example shown in FIG. 15(b), when the second operation section 97 is operated in the fourth operation MR4, the second actuator 96 reduces the assist rate in the landing region RG3. For example, when the second operation part 97 is operated in the fourth operation MR4, the second actuator 96 increases the height of the rotation assisting member 40 (more specifically, the rotation assisting bar 41) from the sliding surface S in the landing area RG3. is decreased from the second height H1 (see FIG. 15(a)) to the first height H1' (see FIG. 15(b)).

The second operation section 97 may include an assist rate input section for inputting an assist rate. In this case, the second actuator 96 automatically adjusts the assist rate in the landing area RG3 so that the assist rate in the landing area RG3 becomes the assist rate input to the assist rate input section.

In the example shown in FIG. 15, the assist rate adjustment mechanism M is a mechanism that adjusts the assist rate by moving the movement trajectory OB'' of the moving member 20 in the vertical direction. Alternatively, the assist rate adjustment mechanism M may be a mechanism that adjusts the assist rate by expanding and contracting the support member 50.

(Second exercise assist device 4-2)
In the example shown in FIG. 1, the somersault motion assist system 1A includes a second motion assist device 4-2. In other words, the somersault motion assist system 1A includes a second motion assist device 4-2 in addition to the above-described motion assist device 4. The second exercise assist device 4-2 has a similar structure to the exercise assist device 4. It is preferable that the second exercise assist device 4-2 is disposed at a position shifted by a half orbit from the exercise assist device 4 in the orbit OB of the endless member 21.

When the somersault motion assist system 1A has two motion assist devices (4, 4-2), when one motion assist device reaches the departure region RG5, the other motion assist device moves near the start region RG1. reach Therefore, after a user leaves one exercise assist device, the next user can immediately use the other exercise assist device.

In the example shown in FIG. 1, in addition to the first moving body 24a, a third moving body 24c is attached to the first endless member 21a. In the example shown in FIG. 1, a fourth moving body 24d is attached to the second endless member 21b in addition to the second moving body 24b. In the example shown in FIG. 1, the second exercise assist device 4-2 is attached to the first endless member 21a via the third moving body 24c, and is attached to the second endless member 21b via the fourth moving body 24d. attached.

The rotation assisting member 40 assists the user's rotation. In the example shown in FIG. 18, the rotation assisting member 40 is wearable by the user. In this case, the rotation assisting member 40 rotates together with the user, thereby assisting the user's rotation.

Support member 50 is connected to moving member 20. Therefore, when the movable member 20 moves, the support member 50 moves together with the movable member 20. The support member 50 supports the rotation assisting member 40.

In the example shown in FIG. 18 , the support member 50 includes a flexible linear member 53 . In other words, the rotation assisting member 40 is supported by the moving member 20 via the flexible linear member 53.

In the second embodiment, when a user jumps from a jumping platform J, a portion of the force transmitted from the jumping platform J to the user is converted into a force that rotates the rotation assisting member 40 and the user. In this way, the somersault motion assist system 1B according to the second embodiment can assist the somersault motion of the user.

(optional additional configuration)

The distance L1 between the first conveyor 2a and the second conveyor 2b is, for example, 2 m or more, 2.5 m or more, or 3 m or more.

In the second embodiment, as the conveyor 2, the conveyor 2 explained in the first embodiment can be used as is. Therefore, in the second embodiment, repeated description of the conveyor 2 will be omitted.

(Rotation auxiliary member 40)
In the example shown in FIG. 20, the rotation assisting member 40 has a mounting tool 43 that is worn by the user.

It may have a two-wire body 531b (for example, a second rubber tube). In other words, the rotation assisting member 40 (more specifically, the mounting tool 43) may be supported by the moving body 24 of the conveyor 2 via the stretchable linear body 531.

When the rotation auxiliary member 40 is supported via the stretchable linear body 531, the rotation auxiliary member 40 moves up and down following the user's up and down movement when the user slides on the upstream course CA. . Therefore, the degree of freedom of the user's posture when skiing on the upstream part of the course CA is ensured.

As illustrated in FIG. 23(a), the first linear member 53a may include a non-stretchable third linear member 533a that prevents excessive stretching of the first linear member 531a. . In the example shown in FIG. 23(a), the non-stretchable third linear body 533a is arranged in parallel to the stretchable first linear body 531a. Note that in this specification, "parallel" also includes "concentric". As illustrated in FIG. 23(b), the state in which the third linear body 533a is tensed defines the limit of elongation of the first linear body 531a. As illustrated in FIGS. 23(a) and 23(b), the third linear body 533a may be arranged inside the tubular first linear body 531a. The third linear body 533a is, for example, a non-stretchable wire.

In the example shown in FIG. 23, a stretchable linear body 531 and a non-stretchable linear body 533 are arranged in parallel. Further, the rotation assisting member 40 is supported by the movable body 24 of the conveyor 2 via both a stretchable linear body 531 and a non-stretchable linear body 533. In this case, the degree of freedom of the user's posture when skiing on the upstream part of the course CA is ensured. In addition, since excessive stretching of the stretchable linear body 531 is prevented, a significant assist rate is achieved when the user performs a landing motion in the landing region RG3.

(Acceleration region RG2)
In the example shown in FIG. 24, the skiing course C has an acceleration region RG2 arranged between the start region RG1 and the jumping hill J. The acceleration region RG2 constitutes a part of the upstream course CA or the entire upstream course CA.

The deceleration region RG4 constitutes a part of the downstream portion CB of the course, and is arranged downstream of the landing region RG3 in the skiing direction.

In the second embodiment, the deceleration region RG4 explained in the first embodiment can be directly adopted as the deceleration region RG4. Therefore, in the second embodiment, a repetitive description of the deceleration region RG4 will be omitted.

(Height adjustment of rotation auxiliary member 40)
In the example shown in FIG. 25, the height of the rotation assisting member 40 (for example, the mounting tool 43) can be adjusted in the start region RG1 of the sliding course C according to the user's height. More specifically, in the example shown in FIG. 25, in the start region RG1 of the skiing course C, the height of the rotation auxiliary member 40 (for example, the mounting tool 43) with respect to the start skiing surface S1 can be adjusted.

In the example shown in FIG. 25, the exercise assist device 4 (more specifically, the support member 50) includes a flexible linear member 53 and a height adjustment member for changing the height of the mounting tool 43. 91. Alternatively, the moving member 20 (more specifically, the moving body 24) of the conveyor 2 may include a height adjusting member 91 for changing the height of the mounting tool 43.

In the example shown in FIG. 25, the height adjustment member 91 includes a first member 92a and a second member 92b whose position can be changed in the vertical direction with respect to the first member 92a. Further, the first member 92a is connected to the base portion 59 of the support member 50, and the second member 92b is connected to the linear member 53 that supports the mounting tool 43. In this case, the height adjustment member 91 can adjust the position of the entire linear member 53 in the vertical direction.

A height adjustment member 91 for changing the height of the rotation auxiliary member 40 (more specifically, the mounting tool 43) has a first actuator 92 for changing the height of the rotation auxiliary member 40. You can. In the example shown in FIG. 25, the first member 92a of the first actuator 92 is a cylinder, and the second member 92b of the first actuator 92 is a rod. Alternatively, the first member 92a of the first actuator 92 may be a threaded rod, and the second member 92b of the first actuator 92 may be a nut member that is threaded onto the threaded rod.

Adjustment of the height of the rotation auxiliary member 40 (more specifically, the mounting tool 43) in the start region RG1 is performed by operating the first operation section 93 disposed in or near the start region RG1. It may be possible to do so. In other words, even if the somersault movement assist system 1B includes the first operating section 93 and the first actuator 92 that adjusts the height of the rotation assisting member 40 by operating the first operating section 93, good.

In the example shown in FIG. 25, when the first operation part 93 is operated MR1, the first actuator 92 increases the height of the rotation assisting member 40 (more specifically, the mounting tool 43). On the other hand, when the first operation portion 93 is operated in the second operation MR2, the first actuator 92 lowers the height of the rotation assisting member 40 (more specifically, the mounting tool 43).

The first operation unit 93 and the first actuator 92 may be configured to be able to communicate wirelessly. Further, the somersault motion assist system 1B may include a first battery 94 that supplies power to the first actuator 92.

The height adjusting member 91 adjusts the height of the rotation assisting member 40 (more specifically, the mounting tool 43) by adjusting the amount of pulling of the linear member 53 in the direction toward the moving body 24 of the conveyor 2. It may be a member to be changed. In the example shown in FIG. 26(a), when the first operation part 93 is operated in the first operation MR1, the amount of traction of the linear member 53 in the direction toward the moving body 24 of the conveyor 2 increases (see arrow E1). reference.). As a result, the height of the rotation assisting member 40 (more specifically, the mounting tool 43) increases. On the other hand, in the example shown in FIG. 26(b), when the first operation part 93 is operated in the second operation MR2, the amount of traction of the linear member 53 in the direction toward the moving body 24 of the conveyor 2 decreases (as indicated by the arrow (See E2). As a result, the height of the rotation assisting member 40 (more specifically, the mounting tool 43) becomes lower.

In the example shown in FIG. 26, the first actuator 92 is employed as a mechanism for increasing (or decreasing) the amount of traction of the linear member 53, and the first member 92a of the first actuator 92 is attached to the base of the support member 50. The second member 92b of the first actuator 92 is connected to the linear member 53. Alternatively, a mechanism for winding up the linear member 53 may be employed as a mechanism for increasing (or decreasing) the amount of traction of the linear member 53. Further alternatively, a cam mechanism may be employed as a mechanism for increasing (or decreasing) the amount of traction of the linear member 53.

(assist rate)
In the example shown in FIG. 27, the assist rate in the landing region RG3 is higher than the assist rate in the upstream part of the course CA. In other words, the height H1 of the rotation assisting member 40 (more specifically, the mounting tool 43) from the running surface S in the landing area RG3 is higher than the height H1 of the rotation assisting member 40 (more specifically, the mounting tool 43) from the running surface S in the upstream part of the course CA. Specifically, it is higher than the height H2 of the mounting tool 43).

Furthermore, in the example shown in FIG. 27, the assist rate in the departure area RG5 is lower than the assist rate in the landing area RG3. In other words, the height H3 of the rotation assisting member 40 (more specifically, the mounting tool 43) from the running surface S in the departure area RG5 is the height H3 of the rotation assisting member 40 (more specifically, the mounting tool 43) from the running surface S in the landing area RG3. Specifically, it is lower than the height H1 of the mounting tool 43).

Note that, as illustrated in FIG. 27, each of "height H1," "height H2," and "height H3" refers to the lower end of the rotation auxiliary member 40 (more specifically, the mounting tool 43). It means the distance between the intersection of the vertical line and the sliding surface S and the lower end of the rotation assisting member 40 (more specifically, the mounting tool 43).

(Assist rate adjustment mechanism M)
In the example shown in FIG. 28, the somersault movement assist system 1B has an assist rate adjustment mechanism M. More specifically, the somersault movement assist system 1B includes rotation assisting member 40 (more specifically, mounting An assist rate adjustment mechanism M is provided that adjusts the height H1 of the rotation assisting member 40 (more specifically, the mounting tool 43) from the sliding surface S in the landing area RG3 without changing the height H4 of the tool 43). have

The assist rate adjustment mechanism M may be able to adjust the assist rate in the landing region RG3 between 0% and 100%.

In the example shown in FIG. 28, the assist rate adjustment mechanism M includes a second actuator 96 that moves the movement trajectory OB'' of the moving member 20 in the vertical direction at a position facing the landing area RG3 in a side view. In the example shown in FIG. 28, the conveyor 2 includes an auxiliary guide body 38 that guides the movement of the moving member 20 (more specifically, the endless member 21) at a position facing the landing area RG3 in a side view. have

In the example shown in FIG. 28, the second actuator 96 moves the movement trajectory OB'' of the moving member 20 (more specifically, the endless member 21) in the vertical direction by moving the auxiliary guide body 38 in the vertical direction. move it to

The assist rate may be adjusted by operating the second operating section 97 arranged in or near the start region RG1. In other words, the somersault motion assist system 1B may include the second operating section 97 and the second actuator 96 that adjusts the assist rate by operating the second operating section 97.

In the example shown in FIG. 28(a), when the second operation section 97 is operated in the third operation MR3, the second actuator 96 increases the assist rate in the landing region RG3. For example, when the second operation part 97 is operated in the third operation MR3, the second actuator 96 adjusts the height of the rotation assisting member 40 (more specifically, the mounting tool 43) from the sliding surface S in the landing area RG3. , from the first height H1' (see FIG. 28(b)) to the second height H1 (see FIG. 28(a)).

On the other hand, in the example shown in FIG. 28(b), when the second operation unit 97 is operated in the fourth operation MR4, the second actuator 96 reduces the assist rate in the landing region RG3. For example, when the second operation part 97 is operated in the fourth operation MR4, the second actuator 96 adjusts the height of the rotation assisting member 40 (more specifically, the mounting tool 43) from the sliding surface S in the landing area RG3. , from the second height H1 (see FIG. 28(a)) to the first height H1' (see FIG. 28(b)).

Note that, as illustrated in FIG. 28, each of "height H1," "height H1'," and "height H4" refers to the lower end of the rotation auxiliary member 40 (more specifically, the mounting tool 43). It means the distance between the intersection of the vertical line passing through and the sliding surface S and the lower end of the rotation assisting member 40 (more specifically, the mounting tool 43).

The second operation section 97 may include an assist rate input section for inputting an assist rate. In this case, the second actuator 96 automatically adjusts the assist rate in the landing area RG3 so that the assist rate in the landing area RG3 becomes the assist rate input to the assist rate input section.

In the example shown in FIG. 28, the assist rate adjustment mechanism M is a mechanism that adjusts the assist rate by moving the movement trajectory OB'' of the moving member 20 in the vertical direction. Alternatively, the assist rate adjustment mechanism M may be a mechanism that adjusts the assist rate by changing the amount of traction of the linear member 53 in the direction toward the moving body 24 of the conveyor 2 in the landing region RG3. good.

(Second exercise assist device 4-2)
In the example shown in FIG. 16, the somersault motion assist system 1B includes a second motion assist device 4-2. In other words, the somersault motion assist system 1B includes a second motion assist device 4-2 in addition to the above-described motion assist device 4. The second exercise assist device 4-2 has a similar structure to the exercise assist device 4. It is preferable that the second exercise assist device 4-2 is disposed at a position shifted by a half orbit from the exercise assist device 4 in the orbit OB of the endless member 21.

(Somersault movement assist method)
A somersault motion assisting method in the embodiment will be described with reference to FIGS. 1 to 31. FIG. 29 is a schematic side view schematically showing how the somersault movement assisting method according to the embodiment is executed. FIG. 30 is a schematic side view schematically showing how a somersault motion assisting method in a modified example of the embodiment is executed. FIG. 31 is a flowchart illustrating an example of a somersault movement assisting method in the embodiment.

The somersault motion assist method in the embodiment is executed using the somersault motion assist system 1. The somersault motion assist system 1 may be the somersault motion assist system 1A in the first embodiment, the somersault motion assist system 1B in the second embodiment, or any other somersault motion assist system. It may be.

The somersault motion assist system 1 includes (1) a conveyor 2 that moves a moving member 20 along a sliding course C with a jumping platform J on which a user wearing a sliding device D slides, and (2) a user who jumps from the jumping platform J. a motion assist device 4 that assists the somersault motion of the vehicle. (3) The exercise assist device 4 includes a rotation assisting member 40 that assists the user's rotation, and a support member 50 that is connected to the moving member 20 and supports the rotation assisting member 40.

The "conveyor 2," "exercise assist device 4," "rotation assisting member 40," and "support member 50" have already been explained in the first embodiment or the second embodiment, so the structure of these components will be explained below. Repetitive explanations will be omitted.

In the first step ST1, in the start region RG1 of the skiing course C, the height of the rotation assisting member 40 (for example, the rotation assisting bar 41 or the mounting tool 43) with respect to the start running surface S1 is adjusted. The first step ST1 is a height adjustment step. As illustrated in FIGS. 12 and 25, the height adjustment step may be performed by operating the first operating section 93 disposed at or near the start region RG1. In the example shown in FIGS. 12 and 25, when the first operation section 93 is operated in the first operation MR1, the first actuator 92 moves the rotation assisting member 40 (for example, the rotation assisting bar 41 or the mounting tool 43). Increase the height. On the other hand, when the first operation section 93 is operated in the second operation MR2, the first actuator 92 lowers the height of the rotation assisting member 40 (for example, the rotation assisting bar 41 or the mounting tool 43).

Note that if the somersault motion assist system 1 does not have a mechanism for adjusting the height of the rotation auxiliary member 40, or for the user who will next ski the sliding course C, it is necessary to change the height of the rotation auxiliary member 40. If there is no one, the first step ST1 is omitted.

In the second step ST2, the assist rate is adjusted. The second step ST2 is an assist rate adjustment step. As illustrated in FIGS. 15 and 28, the assist rate adjustment step includes height H4 of the rotation assisting member 40 (for example, the rotation assisting bar 41 or the mounting tool 43) at a position facing the start sliding surface S1. This is a step of adjusting the height H1 of the rotation assisting member 40 (for example, the rotation assisting bar 41 or the mounting tool 43) in the landing area RG3 without changing the height H1.

As illustrated in FIGS. 15 and 28, the height adjustment step may be performed by operating the start region RG1 or the second operating section 97 disposed near the start region RG1. In the example shown in FIGS. 15 and 28, when the second operation section 97 performs the third operation MR3, the second actuator 96 increases the assist rate in the landing region RG3. On the other hand, when the second operation section 97 is operated in the fourth operation MR4, the second actuator 96 reduces the assist rate in the landing region RG3.

Note that if the somersault motion assist system 1 does not include the assist rate adjustment mechanism M that adjusts the assist rate in the landing area RG3, or if the user skis the next sliding course C, there is no need to change the assist rate. In this case, the second step ST2 is omitted.

The second step ST2 may be executed before executing the first step ST1, or may be executed after executing the first step ST1.

In the third step ST3, the user is connected to the rotation assisting member 40 (for example, the rotation assisting bar 41 or the mounting tool 43). The third step ST3 is a connection process.

In the example shown in FIG. 12, the connecting step includes the rotation assisting bar 41 being held by the user. Additionally, the connecting step may include attaching a user-worn safety device 70 to the rotation assist bar 41 (see FIG. 7). The safety device 70 is attached to the rotation assisting bar 41, for example, by a staff member.

On the other hand, in the example shown in FIG. 25, the connecting step includes attaching the fitting 43 to the user.

The third step ST3 may be executed before executing the first step ST1, or may be executed after executing the first step ST1. Further, the third step ST3 may be executed before executing the second step ST2, or may be executed after executing the second step ST2.

In the fourth step ST4, the moving member 20 of the conveyor 2 is moved along the sliding course C with the sliding device D in contact with the sliding surface S of the upstream course CA of the sliding course C. The fourth step ST4 is a first moving step.

In the first movement step, the user is connected to the rotation assisting member 40 (for example, the rotation assisting bar 41 is grasped by the user, or the mounting tool 43 is attached to the user), and the sliding device The moving member 20 of the conveyor 2 is moved along the sliding course C with D in contact with the sliding surface S of the sliding course C.

By executing the first movement step, the user slides on the upstream course CA of the sliding course C, and the rotation auxiliary member 40 moves along the upstream course CA with the user (arrow AR1 in FIGS. 29 and 30). ).

As illustrated in FIGS. 29 and 30, in the first movement step, the exercise assist device 4 is moved in the acceleration region RG2 of the upstream course CA (for example, the region facing the first slope 11 of the sliding course C). , may include an acceleration step of accelerating the skiing course C. The acceleration step is performed, for example, by the drive device 30 accelerating the moving member 20. As the moving member 20 is accelerated, the exercise assist device 4 connected to the moving member 20 is accelerated toward the jumping hill J.

By executing the acceleration step, the user is accelerated along the first inclined surface 11, and the exercise assist device 4 is accelerated toward the jumping hill J together with the user.

In the fifth step ST5, the moving member 20 of the conveyor 2 is moved along the sliding course C with the sliding device D in contact with the jumping platform J of the sliding course C. The fifth step ST5 is a second moving process.

In the second movement step, the user is connected to the rotation assisting member 40 (for example, the rotation assisting bar 41 is grasped by the user, or the mounting tool 43 is attached to the user), and the sliding device The moving member 20 of the conveyor 2 is moved along the sliding course C with D in contact with the jumping hill J of the sliding course C.

By executing the second movement step, the user slides on the jumping hill J of the sliding course C, and the rotation auxiliary member 40 moves along the jumping hill J together with the user (see arrow AR2 in FIGS. 29 and 30). ).

In the example shown in FIGS. 29 and 30, the second movement step includes a step of moving the exercise assist device 4 at a constant speed with respect to the slide course C in an area facing the jump hill J of the slide course C. or may include a step of decelerating the exercise assist device 4 with respect to the sliding course C. When the exercise assist device 4 is changed from an acceleration state to a constant velocity movement state (or a deceleration state), there is a discrepancy between the movement of the user, which is decelerated on the jump hill J, and the movement of the exercise assist device 4. The occurrence of this is suppressed. Note that the speed adjustment of the exercise assist device 4 is executed, for example, by the drive device 30 adjusting the moving speed of the moving member 20 based on a control command from the control device 28.

In the sixth step ST6, the moving member 20 of the conveyor 2 is moved along the sliding course C while the user has jumped from the jumping platform J of the sliding course C. The sixth step ST6 is a third moving process.

In the third movement step, the user who is jumping from the jumping hill J is connected to the rotation assisting member 40 (for example, the rotation assisting bar 41 is grasped by the user, or the mounting tool 43 is attached to the user). state), the moving member 20 of the conveyor 2 is moved along the sliding course C.

By executing the third movement step, the user jumps from the jumping platform J on the sliding course C, and the rotation assisting member 40 assists the somersault movement of the user while moving along the sliding course C (FIGS. 29 and 30). (see arrow AR3).

In the example shown in FIG. 29, during execution of the third movement step, the user rotates around the rotation assist bar 41 using the rotation assist bar 41 as the rotation axis.

On the other hand, in the example shown in FIG. 30, during execution of the third movement step, the user rotates together with the mounting tool 43 using the end of the support member 50 (for example, the flexible linear member 53) as a fulcrum. Due to this rotation, the linear member 53 may be twisted. Alternatively, when the linear member 53 and the mounting tool 43 are connected via a rotatable joint, the linear member 53 does not need to be twisted by the rotation. Additionally, during execution of the third movement step, the amount of traction of the linear member 53 in the direction toward the moving body 24 of the conveyor 2 may be increased.

In the example shown in FIGS. 29 and 30, the third movement step may include a step of moving the exercise assist device 4 at a constant speed with respect to the sliding course C. By moving the exercise assist device 4 at a constant speed, discrepancies between the movement of the user jumping from the jumping hill J and the movement of the exercise assist device 4 are suppressed.

In the seventh step ST7, the moving member 20 of the conveyor 2 is moved along the sliding course C with the sliding device D facing the landing area RG3 of the sliding course C. The seventh step ST7 is a fourth movement step.

In the fourth movement step, the user is connected to the rotation assisting member 40 (for example, the rotation assisting bar 41 is grasped by the user, or the mounting tool 43 is attached to the user), and the sliding device The moving member 20 of the conveyor 2 is moved along the sliding course C with D facing the landing area RG3 of the sliding course C (see arrow AR4 in FIGS. 29 and 30).

The fourth movement step may include the user actually landing on the landing area RG3. For example, if the above-mentioned assist rate is less than 100%, it is assumed that the user actually lands in the landing area RG3. Alternatively, the fourth movement step may include the user not landing in the landing area RG3, and the floating state of the user being maintained by the moving member 20 and the exercise assist device 4. For example, if the above-mentioned assist rate is 100%, it is assumed that the user does not actually land in the landing area, but that landing is simulated.

By executing the fourth movement step, the user performs a landing motion (including a simulated motion) in the landing region RG3. Further, when the above-mentioned assist rate is higher than 0%, the exercise assist device 4 assists the user's landing motion (including a simulated motion) while moving along the sliding course C. As the user's landing motion is assisted by the exercise assist device 4, the impact that the user receives from the sliding surface in the landing area RG3 becomes zero or is alleviated.

In the eighth step ST8, the moving member 20 of the conveyor 2 is moved along the sliding course C with the sliding device D facing the downstream part CB of the sliding course C. The eighth step ST8 is a fifth moving step.

In the fifth movement step, the user is connected to the rotation assisting member 40 (for example, the rotation assisting bar 41 is grasped by the user, or the mounting tool 43 is attached to the user), and the sliding device The moving member 20 of the conveyor 2 is moved along the sliding course C with D facing the course downstream part CB of the sliding course C (see arrow AR5 in FIGS. 29 and 30).

The fifth movement step may include the user sliding on the downstream course portion CB of the sliding course C. In other words, the fifth movement step may be performed while the sliding device D worn by the user is in contact with the sliding surface of the downstream portion CB of the course. Alternatively, in the fifth movement step, the user does not slide on the downstream part CB of the course and the floating state of the user is maintained by the moving member 20 and the exercise assist device 4, and the user moves toward the downstream part CB of the course. This may include moving.

As illustrated in FIGS. 29 and 30, in the fifth movement step, the exercise assist device 4 is moved in the deceleration region RG4 of the downstream part CB of the course (for example, the region facing the second slope 14 of the sliding course C). , may include a deceleration step of decelerating the skiing course C. The deceleration process is performed, for example, by the drive device 30 decelerating the moving member 20.

By executing the deceleration process, the user and the exercise assist device 4 are decelerated as they move toward the withdrawal region RG5. In this case, the user can safely leave the exercise assist device 4 in the withdrawal area RG5 downstream of the deceleration area RG4.

In the ninth step ST9, the connection between the user and the rotation assisting member 40 (for example, the rotation assisting bar 41 or the mounting tool 43) is released. The ninth step ST9 is a disconnection step.

In the example shown in FIG. 29, the disconnection step includes releasing the rotation assisting bar 41 from the user's grip. Additionally, the disconnection step may include removing the user-worn safety device 70 from the rotation assist bar 41. The safety device 70 is removed from the rotation assisting bar 41, for example, by a staff member.

On the other hand, in the example depicted in FIG. 30, the disconnection step includes the attachment 43 being removed from the user.

Furthermore, in the above-described embodiment, an example has been described in which the upstream portion of the course CA is a downwardly sloping surface whose height decreases as it approaches the jumping hill J. However, in the embodiment, the upstream course portion CA (or the downstream course portion CB) is not limited to a downward slope.
