<How to use the exercise apparatus 10>
As shown in FIGS. 1 and 2, the user of the exercise device 10 opens the first hinge 21 to bring the slide rails 13 and 14 into a state of being horizontally deployed.

When the user opens and closes both feet placed on the footrests 11 and 12 with both hands placed on the grip 22b of the handle 22, the footrests 11 and 12 are respectively moved to the slide rails 13 and 14, respectively. Because the slide is slidable, a slide-type open leg movement can be performed.
At this time, if the user grips the grip 22b strongly, it is difficult to apply the force to the gluteal muscles as much as the force is applied to both hands, and the exercise effect is hindered. Is preferred.

As shown in FIG. 5, the user opens both feet, and the footrests 11 and 12 are separated from each other, and each foot is placed on the side of the distal end portion 13c and 14c from the intermediate position 40a of the rail track 40 of each slide rail 13 and 14. When the pedestals 11 and 12 move, the rubber string 57 is pulled and stretched, and the tensile elastic force (degenerative force) of the rubber string 57 is transmitted to each footrest 11 and 12 via the nylon string 58.
Then, as indicated by an arrow α in FIG. 5, a load due to the tensile elastic force of the rubber cord 57 is applied to the footrests 11 and 12 in the extending direction of the rail track 40, and each footrest 11 and 12. It is given in the opposite direction (proximity direction) to the separation direction.
Here, since the rubber cord 57 is wound around the third pulley 53, the third pulley 53 functions as a fixed pulley, and the load due to the tensile elastic force of the rubber cord 57 is changed by 180 °. The direction is indicated by the arrow α.

As shown in FIG. 6, when the user opens both feet moderately and each footrest 11, 12 moves to an intermediate position 40 a of the rail track 40 of each slide rail 13, 14, the rubber string 57 is in a contracted steady state. Therefore, the tensile elastic force of the rubber cord 57 becomes zero, so that the load applied to the footrests 11 and 12 becomes zero.

As shown in FIG. 7, the user closes both feet and the footrests 11 and 12 are close to each other, and each of the slide rails 13 and 14 is closer to the base end portions 13 a and 14 a than the intermediate position 40 a of the rail track 40. When the footrests 11 and 12 move, the rubber cord 57 is pulled and stretched, and the tensile elastic force of the rubber cord 57 is transmitted to the footrests 11 and 12 via the nylon cord 58.
Then, a load due to the tensile elastic force of the rubber cord 57 is applied to the footrests 11 and 12 in the extending direction of the rail track 40 as indicated by an arrow β in FIG. Is applied in a direction opposite to the proximity direction (separation direction).
Here, since the pulleys 53 and 54 are arranged in the load application direction indicated by the arrow β in FIG. 7, the nylon string 58 passed between the pulleys 53 and 54 receives a force from the pulleys 53 and 54. The load applied to the footrests 11 and 12 is not affected by the pulleys 53 and 54 at all.

By the way, as shown in FIGS. 6 and 7, the fourth pulley 54 has each footrest 11, 12 between the base end portions 13 a, 14 a of the slide rails 13, 14 and the intermediate position 40 a of the rail track 40. In order to prevent the nylon string 58 from unnecessarily swinging when moving, the nylon string 58 is provided between the pulleys 53 and 54.

<Storage method of exercise equipment 10>
The user lifts the tips of the housings 32 and 33 upward to bring the first hinge 21 into a closed state, and folds and integrates the housings 32 and 33 so as to be closed.
Subsequently, the user lifts the rear side of each of the integrated housings 32 and 33 upward and pulls down the housings 32 and 33 toward the handle 22 so that the second hinge 31 is closed. The housings 32 and 33 are folded and integrated so as to be combined with the handle 22 side.

Thus, in the state which closed each hinge 21,31, each housing | casing 32,33 and the handle | steering-wheel 22 are folded and integrated, and the substantially fan-shaped plate which each housing | casing 32,33 and the handle | steering-wheel 22 stood upright as a whole. It becomes a shape.

Since the applied load is in the direction indicated by arrow α, it is possible to exert an exercise effect on the gluteal muscle group.
Further, as shown in FIG. 7, when the footrests 11, 12 move from the intermediate position 40 a of the rail track 40 of the slide rails 13, 14 toward the base end portions 13 a, 14 a, Since the applied load is in the direction indicated by the arrow β, an exercise effect can be exerted on the adductor muscle group.
The arrows α and β indicate opposite directions.

In the exercise device 10, in order to switch between the exercise of the gluteal muscle group and the exercise of the adductor muscle group, the user may simply perform an open leg exercise that opens and closes both feet.
Therefore, according to the present embodiment, it is possible to exert an exercise effect on both the gluteal muscle group and the adductor muscle group, and it takes time to switch between the gluteal muscle group movement and the adductor muscle group movement. The exercise apparatus 10 that does not require work can be provided.

[2] As shown in FIGS. 1 to 4, the slide rails 13 and 14 have base end portions 13a and 14a and tip end portions 13c and 14c, respectively, and the base end portions 13a and 14a of the slide rails 13 and 14 are provided. Are arranged in close proximity via a first hinge 21.
As shown in FIGS. 5 and 7, the load applying unit 60 includes a first urging unit 61 that urges the footrests 11 and 12 toward the base end portions 13 a and 14 a, and each footrest 11, Since the second urging means 62 that urges 12 toward the distal end portions 13c and 14c is provided, the operation and effect of [1] can be obtained with certainty.

[3] As shown in FIGS. 5 to 7, the load applying means 60 includes a first elastic rubber member 57 (a tensile elastic member) having first to fourth pulleys 51 to 54, a first end portion 57a, and a second end portion 57b. ) And a nylon string 58 (non-elastic string material) having a first end 58a and a second end 58b.
The pulleys 51 and 52 are attached to the front end portions 13c and 14c of the slide rails 13 and 14, respectively.
The pulleys 53 and 54 are arranged in the load application direction and attached to an intermediate position 40 a of the rail track 40 of the slide rails 13 and 14.
The first end portion 57 a of the rubber cord 57 is detachably attached and fixed to the base end portions 13 a and 14 a of the slide rails 13 and 14, and the second end portion 57 b of the rubber cord 57 is the first end of the nylon cord 58. It is detachably attached and fixed to the portion 58a.
The second end 58 a of the nylon string 58 is hung on the pulleys 51 and 52, and then attached and fixed to the footrests 11 and 12 through the pulleys 53 and 54.

The first urging means 61 includes a nylon string 58 wound around the third pulley 53 and a rubber string 57.
The second urging means 62 includes a nylon string 58 passed between the third pulley 53 and the fourth pulley 54, and a rubber string 57.
Therefore, the urging means 61 and 62 can be embodied with a simple configuration at low cost, and the operation and effect of [2] can be easily obtained.

Here, since both end portions 57a and 57b of the rubber cord 57 are formed in an annular shape, the first end portion 57a of the rubber cord 57 can be easily attached to and detached from the hooking member 55. The two end portions 57b can be easily attached to and detached from the hook material of the first end portion 58a of the nylon string 58.
Further, as shown in FIG. 6, in the steady state of the rubber cord 57, the lengths of the cords 57 and 58 are set so that the first end portion 58a of the nylon cord 58 is located in the vicinity of the pin material 56. Therefore, the rubber cord 57 can be easily attached and detached.

By the way, since the load applied to the footrests 11 and 12 depends on the tensile elastic force of the rubber cord 57, there is an effect that the load gradually increases as the footrests 11 and 12 move away from the intermediate position 40a. Further, if a plurality of types of rubber cords 57 having different tensile elastic forces are prepared and replaced with rubber cords 57 having different tensile elastic forces, each of the footrests 11 and 12 is provided according to the exercise effect required by the user. Can be changed load.

In addition, when attaching and detaching the rubber cord 57, as shown in FIG. 3, the lids 34 and 35 may be removed from the housings 32 and 33, and the hooking member 55 and the cords 57 and 58 may be exposed.
Incidentally, when the nylon cord 58 is omitted and the second end portion 57b of the rubber cord 57 is attached and fixed to the footrests 11 and 12, the rubber cord 57 is rubbed against each of the pulleys 51 to 54, and the rubber cord 57 is easily hurt. It takes a great deal of time to replace the string 57.
That is, in the exercise device 10, by providing the nylon string 58, it is possible to avoid pain of the rubber string 57 due to rubbing against each of the pulleys 51 to 54, and to reduce time and effort for replacing the rubber string 57.

[4] In the exercise apparatus 10, each slide rail 13, 14 includes a first load portion that applies a load in a direction opposite to the separation direction when the foot placement tables 11, 12 are separated from each other, And a second load section that applies a load in a direction opposite to the approaching direction when the 12 approach each other.
Here, since the first load portion functions in the same manner as the first urging means 61 and the second load portion functions in the same manner as the second urging means 62, the same operation and effect as the above [1] are obtained. be able to.

The first load section and the second load section do not reverse the direction in which the load is applied to the footrests 11 and 12 from the middle of the rail track 40 as in the load applying means 60, but the entire rail track 40. A load may be applied to each of the footrests 11 and 12 in the region.

[5] In the above [4], the first load section applies a load in a direction opposite to the separation direction when the footrests 11 and 12 are separated from the neutral position.
The second load unit applies a load in a direction opposite to the approaching direction when the footrests 11 and 12 are close to each other from the neutral position.

Here, if the neutral position of each of the footrests 11 and 12 is set to the intermediate position 40a of the rail track 40, the same operation and effect as the above [1] and [2] can be obtained.
The neutral position of each footrest 11 and 12 is not limited to the intermediate position 40a of the rail track 40, and may be set to an appropriate position of the rail track 40. Thereby, you may make it produce a difference in the load by the case where the footrests 11 and 12 are separated, and the case where it approaches.

[6] The pulleys 53 and 54 are arranged in the load application direction and attached to the neutral positions of the footrests 11 and 12 on the slide rails 13 and 14.
The first load unit includes a nylon string 58 wound around the third pulley 53 and a rubber string 57, and applies a load by urging the footrests 11 and 12 in the approaching direction.
The second load portion includes a nylon string 58 passed between the third pulley 53 and the fourth pulley 54, and a rubber string 57, and is loaded by energizing the footrests 11 and 12 in a separating direction. give.
Therefore, the first load unit and the second load unit can be realized with a simple configuration at low cost, and the same operation and effect as the above [3] can be obtained.

[7] As shown in FIGS. 1 to 4, in a state where the first hinge 21 is opened, the slide rails 13 and 14 are deployed in line symmetry with respect to the first hinge 21, and the rear side of the exercise device 10. It curves toward (the back side of the user) and has a generally arcuate shape as a whole.
For this reason, in the exercise apparatus 10, since the footrests 11 and 12 slide on the substantially arc-shaped slide rails 13 and 14, the trajectory of both legs when performing the leg-opening motion is also arc-shaped, and a wide range of gluteal muscle groups Can exert an exercise effect.

[8] Each slide rail 13, 14 includes two rails 15, 16 arranged in parallel.
Therefore, compared to the case where each slide rail 13, 14 is configured with only one rail, the exercise device 10 slides each slide rail 13, 14 in a state where each footrest 11, 12 is stable, The exercise effect can be enhanced.

[9] Incidentally, when the rails 15 and 16 are horizontally arranged in a straight line when viewed from the front, the distance between the tip portions 13c and 14c of the slide rails 13 and 14 and the intermediate position 40a of the rail track 40 is provided. As each footrest 11, 12 moves, the user's center of gravity moves downward as the user opens both feet, and conversely, as the user closes both feet, the user's center of gravity moves upward. Since the user's center of gravity moves up and down greatly, the exercise effect is hindered.

Therefore, in the exercise apparatus 10, the rails 15 and 16 are curved so as to rise from the tip portions 13c and 14c of the slide rails 13 and 14 to the intermediate position 40a of the rail track 40 toward the tip portions 13c and 14c. Is formed.
Thereby, even when the user opens and closes both feet when the footrests 11 and 12 move between the end portions 13c and 14c of the slide rails 13 and 14 and the intermediate position 40a of the rail track 40, the user The center of gravity hardly moves up and down, so the exercise effect can be enhanced.

[10] Incidentally, in the case where the pin material 56 is not provided, the length of the retaining member 55 is increased so that the strings 57 and 58 do not hinder the movement of the footrests 11 and 12. The strings 57 and 58 need to be stretched away from the rail 15, and the hook members 55 and the housings 32 and 33 that accommodate the strings 57 and 58 become large, so that the exercise apparatus 10 is enlarged.
Therefore, by providing the pin material 56 for hanging the rubber string 57, it is possible to reduce the overall length of the latching member 55 and to stretch the strings 57, 58 to a position close to the rail 15, and the latching member 55. And since each housing 32 and 33 which accommodates each string 57 and 58 becomes small, the exercise device 10 can be reduced in size.
It should be noted that the pin material 56 may be placed in an experimental position so that the cords 57 and 58 do not hinder the movement of the footrests 11 and 12 and the housings 32 and 33 become smaller.

[11] Since the pulleys 51 and 52 are respectively attached to the front ends of the rails 15 and 16, the strings 57 and 58 can be stretched around the rails 15 and 16.

[A] In the above [2] and [3], the second urging means 62 is omitted, and inclined portions formed on the slide rails 13 and 14 are provided so as to rise toward the base end portions 13a and 14a. In this case, the inclined portion functions in the same manner as the second urging means 62.
Further, in [6], the pulleys 53 and 54 and the strings 57 and 58 are omitted from the second load portion, and formed on the slide rails 13 and 14 so as to rise toward the base end portions 13a and 14a. You may make it a 2nd load part provide an inclination part.
The inclined portions of the slide rails 13 and 14 provided so as to rise toward the base end portions 13a and 14a and the distal end portions 13c and 14c can be adjusted by appropriately adjusting the inclination of each of the footrests 11 and 12. Regardless of the separation distance from the neutral position, it can function as a device that applies a constant load.
