Are placed on a pair of left and right pedals and alternately pushed left and right (for example, Japanese Patent Publication No. Sho 62-11872).

[0003]

Generally, it is desired that a training machine not only be a whole-body exercise that consumes a large amount of energy but also work directly on a part to be tightened to train muscles of the part. However, the conventional training machine merely repeats bending and stretching exercises by alternately pushing and operating both legs, and mainly focuses on slimming due to energy consumption. Therefore, it is unsuitable for training a person who trains for slimming or the like, in which he or she wants to tighten the muscles of the buttocks and abdomen.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a training machine capable of training the gluteal and abdominal muscles to be tightened while performing a whole-body exercise that consumes a large amount of energy. It is.

In order to achieve the above object, a training machine according to the first aspect of the present invention comprises a seat on which an object to be trained is seated, a pair of left and right pedals on which a foot is mounted, and a pedal mounted on each pedal. A training machine comprising: an engaging portion that engages with the instep of the foot; and a load portion that applies a load when the pedal rotates, wherein the pair of left and right pedals can rotate simultaneously in the same phase with each other. The trajectory of the first stroke moving from the first rotation position to the second rotation position is set to have a vertically elongated substantially semicircular or substantially semielliptical arc, and the pedal is moved from the second rotation position. The trajectory of the second stroke moving to the first rotation position is set to have a substantially semicircular arc. The training machine according to the second aspect of the present invention includes a seat portion on which an object to be trained is seated, a pair of left and right pedals on which a foot is mounted, an engaging portion attached to each pedal and engaging with the instep, In the training machine comprising a load portion that applies a load during rotation, the pair of left and right pedals can be simultaneously rotated in the same phase with each other, and the trajectory of the depression stroke in which the pedal descends from the upper rotation position to the lower rotation position is
It is characterized in that it is set to have a vertically long semi-circular or semi-elliptical arc.

According to the present invention, the pushing motion and the pulling motion are alternately performed by placing the feet of both legs and pedaling the pair of left and right pedals simultaneously in the same phase. By setting the trajectory of the downward stroke in the simultaneous pedaling stroke to a vertically long semi-circular or semi-elliptical arc, instead of the exercise of stretching the knee with the thigh muscle, the leg in the buttocks muscle is directed to the ground direction In the downward stroke, a load is mainly applied to the buttocks muscles, and the buttocks muscles are trained. In addition, during the lifting process, a load is applied to the abdominal muscle, and the abdominal muscle is strengthened.

In the present invention, of the simultaneous pedaling strokes, the trajectory of the depression stroke has a substantially semicircular arc or a substantially elliptical arc, and the radius of curvature is set to a larger value than the trajectory of the lifting stroke. It should just be done. In particular, by setting the trajectory of the lifting stroke to have a substantially semicircular arc, the force required for the lifting operation can be reduced. Therefore, the load on the abdominal muscles is relatively small, and the buttocks and the abdominal muscles can be trained with good balance.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 5 show a first embodiment. In FIG. 1, a training machine A has grounding legs 2 and 2 fixed to both ends of a frame 1 in a longitudinal direction.
It is configured as a stationary type. A seat (seat portion) 4 with a backrest 4a on which the trainee sits is fixedly supported via a vertical support member 3 at a position near one of the grounding legs 2 of the frame 1. On both sides of this seat 4,
The gripping rods 5, 5 which the trainee grasps with hands are provided.

As shown in FIG. 2, a pair of left and right pedals 6 and 6 on which the feet of both legs are placed, and a cumulative rotation are provided at a position near the other grounding leg 2 of the frame 1, that is, in front of the seat 4. A setting display 7 having a display window 7a for displaying the number, rotation speed or various set values is provided. As shown in FIGS. 2 and 3, the pair of left and right pedals 6, 6 are provided with band-shaped engaging portions 8, 8 for engaging with the insteps of the feet placed on the pedals 6 to prevent the feet from separating. Installed. Also, the cranks 6b, 6 of the pair of left and right pedals 6, 6
b is configured to be stretchable.

The crank 6 of the pair of left and right pedals 6, 6
The b and 6b are connected to each other via a shaft 10, so that a pair of left and right pedals 6 and 6 can be simultaneously rotated in the same phase. A load device (load section) 9 for applying a load when the pair of left and right pedals 6, 6 is simultaneously rotated is provided above the portion of the frame 1 between the pair of left and right pedals 6, 6. As the load device 9, for example, a shaft 10 directly connecting a pair of left and right cranks 6b, 6b and a flywheel 11 rotatably supported at a position distant therefrom are magnetically braked by pulleys (not shown) or the like. To apply a rotational load. The load can be changed by operating the setting display 7.

Flat cam plates 12, 12 are fixed to the frame 1 inside the pair of left and right pedals 6, 6, respectively. As shown in FIG. 3, the cam plates 12, 12 have cam grooves 13, 13 for guiding the rotational movement of the pedals 6, 6. The pin-shaped projections 14, 14 of FIG. 2 protruding from the pedals 6, 6 are engaged in the cam grooves 13, 13.
The orbit for the rotational motion of is determined.

As shown in FIG. 4, the orbit for the rotational movement of the pedals 6, 6 is a trajectory Gd of a depression stroke in which the pedal 6 descends from the upper rotational position P1 to the lower rotational position P2.
The pedal 6 is set to have a semi-elliptical arc.
Is set so that the orbit Gu of the lifting stroke from the lower rotation position to the upper rotation position has a semicircular arc. The semi-elliptical trajectory Gd of the downward stroke and the semi-circular trajectory Gu of the upward stroke generally have a larger radius of curvature in the semi-elliptical trajectory Gd of the downward stroke than the semi-circular trajectory Gu of the upward stroke (crank). 6b is shortened).

The training machine A having the above configuration
Is used as shown in FIG. That is, the trainee M places the feet F of the legs L thrown forward in the sitting posture on the seat 4 on the pair of left and right pedals 6 and engages the band-shaped engaging portions 8 with the insteps of the feet F. .

In this state, the trainee M pedals the pair of left and right pedals 6 having the same phase at the same time, so that the whole body exercises by alternately pressing down and lifting up. Here, when pushing down the pedal 6 from the upper rotational position P1 to the lower rotational position P2 along the semi-elliptical orbit Gd, a force to lower the foot downward is required as shown by an arrow f1 in FIG. Since the force f1 is applied as a load to the muscles of the buttocks Mh of the trainee M in the sitting posture, the muscles of the buttocks Mh are trained.

When the pedal 6 is lifted from the lower rotational position P2 to the upper rotational position P1 along the semicircular track Gu, the knee can be rotated so as to bend and pull back. As shown in the figure, since the length of the crank 6b of the pedal 6 becomes long, a small force is required, but the force f2 is applied as a load to the muscle of the abdomen Mb of the trainee M in the sitting posture, and the muscle of the abdomen Mb is strengthened. Can be

As described above, in the training machine A according to the first embodiment, the push-down and pull-up exercises are continuously performed while the local exercises for directly applying a load to the muscles of the buttocks Mh and the abdomen Mb to be tightened most are mainly performed. By doing so, it is possible to realize a whole body exercise that consumes a large amount of energy.

In the first embodiment, the orbit Gu of the lifting stroke is set to have a semicircular arc. However, as shown in FIG. 6, the orbit Gu is set to have a semielliptical arc. Is also good. That is, the track itself may be elliptical. In this case, the length of the crank 6b is shortened during the lifting process, and a considerably large load is applied to the muscle of the abdomen Mb. However, when it is desired to strongly train the muscle of the abdomen Mb, this can be suitably adopted.

In the first embodiment, the trajectory Gd of the depression stroke is set to have a semi-elliptical arc. However, as shown in FIG. 7, a vertically long trajectory obtained by combining an arc R and a straight line L1 is used. It may be set so as to have a substantially semi-oval trajectory.

In the present invention, a pair of left and right pedals 6 are provided in phase with each other and rotate simultaneously, and a pair of left and right pedals 6 are provided with a phase difference of 180 ° and rotate left and right alternately. It may be configured to be switchable between. Further, the present invention uses the trajectory of the pedal as a main part of the present invention, and does not limit the mechanical structure of the training machine.

The upper rotational position P1 and the lower rotational position P2 may be set to the positions shown in FIGS. 4 and 5, or may be set to the positions shown in FIG. Further, in the present invention, the upper rotational position P1 shown in FIG. 8A may be within a range of α = 45 ° from directly above the rotational center O of the pedal 6. On the other hand, the lower rotation position P2 may be in a range of β = 45 ° from immediately below the rotation center O of the pedal 6. A vertically elongated semi-circular or semi-elliptical arc portion Rx is shown in FIG.
As shown in (b), it is sufficient that the rotation angle is θ = 90 ° or more, and generally, θ = 120 ° or more. Further, since the appropriate position of the arc portion Rx changes depending on the posture of the person performing the training, the trajectory may be rotated around the point O, and may be set, for example, directly below.

[0021]

As described above, according to the present invention,
Since the trajectory of the push-down stroke is set to have a vertically elongated semi-circular or semi-elliptical arc, when the pair of left and right pedals are simultaneously pushed down from the upper rotational position to the lower rotational position in the same phase, Because it is necessary to exercise not to extend the knee but to swing the leg down toward the ground,
Load is applied to the buttocks. On the other hand, the force of simultaneous lifting in the same phase is applied to the abdomen as a load. Therefore, it is possible to realize a whole-body exercise that consumes a large amount of energy by the continuous operation of pushing and pulling the pedal while mainly performing the exercise for sufficiently training the buttocks and abdominal muscles.

In particular, if the trajectory of the pedal during the lifting process is set to have a substantially semicircular arc, the force of the lifting operation can be reduced, so that the load on the abdominal muscles is reduced and the load on the buttocks is reduced. Good balance with load, suitable for making a smart and beautiful body.
