  The present invention has been made to solve the above-mentioned problems, and its purpose is to be able to exert a movement effect on both the gluteal muscles and the adductor muscle group. An object of the present invention is to provide an exercise device that does not require laborious work to switch between exercises of muscle groups.

  As a result of intensive studies in order to solve the above-mentioned problems, the present inventors have arrived at each aspect of the present invention as follows.

<First aspect>
The first aspect is
A right foot footrest on which the user's right foot can be placed;
A left foot footrest on which the user's left foot is placed;
A right foot slide rail portion in which a foot stand for a right foot is slidably mounted along a rail track; and
A left foot slide rail portion in which a foot stand for the left foot is slidably mounted along the rail track, and
Load means is applied to each footrest in the direction of extension of the rail track, and load means for reversing the load force application direction from the middle of the rail track on which each footrest slides each slide rail portion. It is an exercise device for performing a sliding leg movement.

In the first aspect, 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.

The exercise apparatus 10 that does not require such work can be provided.

By the way, in Japanese Patent Laid-Open No. 7-275418, in a training apparatus for simulating an exercise process of a skier during Wedeln, the front ends of two parallel beams can swing in parallel with each other. The treads of the left and right feet of the user are formed at the rear end of each beam, and the rear end of each beam is supported by a curved support piece so that it can slide or roll. Is disclosed.
In the technique disclosed in Japanese Patent Laid-Open No. 7-275418, when the moving direction of the tread surface is switched from the left and right end portions of the support piece toward the opposite end portion, the application direction of the load force applied to the tread surface is reversed.
However, Japanese Patent Application Laid-Open No. 7-275418 does not disclose any information about reversing the direction in which the load force applied to the tread is applied during the movement of the tread and the leg opening movement. Not even done.
For this reason, it is difficult for even a person skilled in the art to conceive the first aspect based on Japanese Patent Laid-Open No. 7-275418, and the action and effect of the first aspect cannot be predicted. Absent.

<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 portion 21 to cause the slide rail portions 13 and 14 to be deployed horizontally.

Then, when the user opens and closes both feet placed on the footrests 11 and 12 with both hands placed on the handrest 22b of the handle portion 22, the footrests 11 and 12 are respectively connected to the slide rails. Since the parts 13 and 14 are slid, a sliding leg opening motion can be performed.
At this time, if the user grips the hand placement part 22b strongly, the force exerted on both hands is less likely to be applied to the gluteal muscle group, and the exercise effect is hindered, so both hands are lightly attached to the hand placement part 22b. It is necessary to put it to the extent.

As shown in FIG. 5, the user opens both feet, and the footrests 11 and 12 are separated from each other, and the slide rail portions 13 and 14 are moved from the intermediate position 40a of the rail track 40 toward the distal end portions 13c and 14c. When the footrests 11 and 12 move, the rubber cord 57 is pulled and stretched, and the tensile elastic force (retraction force) of the rubber cord 57 is transmitted to each footrest 11 and 12 via the nylon cord 58.
Then, the load force 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 shown by the arrow α in FIG. 12 is applied in the direction opposite to the separation direction (proximity 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 direction in which the load force due to the tensile elastic force of the rubber cord 57 is changed by 180 °, FIG. In the direction indicated by arrow α.

  As shown in FIG. 6, when the user appropriately opens both feet and each footrest 11, 12 moves to the intermediate position 40 a of the rail track 40 of each slide rail portion 13, 14, the rubber string 57 is contracted steady. Since the tension elastic force of the rubber cord 57 becomes zero, the load force 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 are closer to the base end portions 13 a and 14 a than the intermediate position 40 a of the rail track 40 of the slide rail portions 13 and 14. 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 through the nylon cord 58.
Then, the load force 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 the arrow β in FIG. 12 is applied in a direction opposite to the proximity direction (separation direction).
Here, since the pulleys 53 and 54 are arranged in the direction of applying the load force indicated by the arrow β in FIG. 7, the nylon string 58 passed between the pulleys 53 and 54 receives force from the pulleys 53 and 54. Is not applied, and the load force applied to the footrests 11 and 12 is not affected by the pulleys 53 and 54 at all.

  Incidentally, as shown in FIGS. 6 and 7, the fourth pulley 54 is provided between the base end portions 13 a and 14 a of the slide rail portions 13 and 14 and the intermediate position 40 a of the rail track 40. Is provided to hold the nylon string 58 between the pulleys 53 and 54 in order to prevent the nylon string 58 from unnecessarily swinging when the is moved.

<Storage method of exercise equipment 10>
The user lifts the tip portions of the respective housing portions 32 and 33 upward to bring the first hinge portion 21 into a closed state, and folds and integrates the respective housing portions 32 and 33 so as to be closed.
Subsequently, the user closed the second hinge portion 31 by lifting the rear side of the integrated housing portions 32 and 33 upward and pulling the housing portions 32 and 33 down to the handle portion 22 side. The housings 32 and 33 are folded and integrated so as to be combined with the handle 22 side.

In this way, in a state in which the hinge portions 21 and 31 are both closed, the housing portions 32 and 33 and the handle portion 22 are folded and integrated, and the housing portions 32 and 33 and the handle portion 22 are entirely upright. It becomes a substantially fan-shaped flat plate shape.
Therefore, the exercise device 10 can be folded compactly during storage, so that the floor occupation area can be reduced and the storage space can be reduced.

The second end portion 58 a of the nylon string 58 is attached to and fixed to the footrests 11 and 12 through the pulleys 53 and 54 after being hooked on the pulleys 51 and 52.

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 positioned 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 force applied to each footrest 11 and 12 is due to the tensile elastic force of the rubber cord 57, a plurality of types of rubber cords 57 having different tensile elastic forces are prepared, If it exchanges, according to the exercise | movement effect which a user requests | requires, the load force applied to each footrest base 11 and 12 can be changed.

When attaching or detaching the rubber cord 57, as shown in FIG. 3, the lid portions 34 and 35 are removed from the housing portions 32 and 33, and the latch member 55 and the cords 57 and 58 are exposed. Good.
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 the pulleys 51 to 54, and the rubber cord 57 is easily painful. 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 the pain of the rubber string 57 due to rubbing against each of the pulleys 51 to 54, and to reduce the labor for replacing the rubber string 57.

[4] In the exercise apparatus 10, each slide rail portion 13, 14 includes a first load portion that applies a load in a direction opposite to the separation direction when the respective footrests 11, 12 are separated from each other, and each footrest 11 , 12 are provided with a second load section that applies a load in a direction opposite to the approaching direction when approaching 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 force is applied to the footrests 11 and 12 from the middle of the rail track 40, unlike the load 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 portion applies a load in a direction opposite to the separation direction when the footrests 11 and 12 are separated from the neutral position.
When the footrests 11 and 12 are close to each other from the neutral position, the second load unit applies a load in a direction opposite to the proximity direction.

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 operations and effects as the above [1] and [2] can be obtained.
The neutral positions of the footrests 11 and 12 are not limited to the intermediate position 40a of the rail track 40, and may be set to appropriate positions on the rail track 40.

[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 in the slide rail portions 13 and 14.
The first load portion 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 separated 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 FIG. 1 to FIG. 4, in a state where the first hinge portion 21 is opened, the slide rail portions 13 and 14 are deployed symmetrically with respect to the first hinge portion 21, and the exercise device 10 Is curved toward the rear side (back side of the user), and has a substantially arc shape as a whole.
For this reason, in the exercise device 10, since the footrests 11 and 12 slide on the slide rail portions 13 and 14 having a substantially arc shape, the trajectory of both feet when performing the leg-opening exercise is also an arc shape, and a wide range of gluteal muscles. Can exert exercise effects on groups.

[8] Each slide rail portion 13, 14 includes two rails 15, 16 arranged in parallel.
Therefore, compared with the case where each slide rail part 13 and 14 is comprised only with one rail, in the exercise device 10, it slides each slide rail part 13 and 14 in the state where each footrest base 11 and 12 was stabilized. Therefore, the exercise effect can be enhanced.

  [9] Incidentally, when the rails 15 and 16 are arranged horizontally in a straight line when viewed from the front, the distance between the end portions 13c and 14c of the slide rail portions 13 and 14 and the intermediate position 40a of the rail track 40 is shown. When the footrests 11 and 12 are moved, the center of gravity of the user moves downward as the user opens both feet, and conversely, the center of gravity of the user moves upward as the user closes both feet. In addition, since the center of gravity of the user moves up and down greatly, the exercise effect is hindered.

Therefore, in the exercise apparatus 10, in the rails 15 and 16, the distance from the tip portions 13c and 14c of the slide rail portions 13 and 14 to the intermediate position 40a of the rail track 40 is raised toward the tip portions 13c and 14c. It is curved.
As a result, when the footrests 11 and 12 move between the tip end portions 13c and 14c of the slide rail portions 13 and 14 and the intermediate position 40a of the rail track 40, even if the user opens and closes both feet, it is used. Since the center of gravity of the person hardly moves up and down, the exercise effect can be enhanced.

[10] Incidentally, when the pin member 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 housing parts 32 and 33 that accommodate the strings 57 and 58 become large. .
Therefore, by providing the pin material 56 for hanging the rubber string 57, the entire length of the latching member 55 can be reduced, and the strings 57, 58 can be stretched close to the rail 15, so that the latching member 55 And since each frame part 32 and 33 which accommodates each string 57 and 58 becomes small, the exercise device 10 can be reduced in size.
In addition, the arrangement | positioning location of the pin material 56 should just find an optimal location experimentally so that each frame part 32 and 33 may become small, without each string 57 and 58 preventing the movement of each footrest base 11 and 12. FIG. .

  [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.
