DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a training apparatus, and more particularly to a training apparatus suitable for health management, athletes, and the like.

[0002]

BACKGROUND OF THE INVENTION Originally, the purpose of training is to increase the physical flexibility, balance and speed of the trainer. In this training, it is said that it is only necessary to move the body to overcome some load, thereby strengthening the muscles, joints, etc. Conventionally, rubber tube machines, spring elastic machines, hydraulic machines, etc. have been used for this training. It is commonly used.

When these machines are used, for example, a body in a bent state is subjected to elasticity such as rubber or a spring, or hydraulic pressure as a load, and is extended against the load. In this case, the load at the time of starting the extension operation from the bending state of the body (initial state) is called an initial load,
When the load at the time of reaching the final extension state (final state) is referred to as a final load, the initial load is small in the machine described above, and the load increases as the operation proceeds,
The final load is at its maximum. Hereinafter, the training machine having the maximum final load in the final state of the operation as described above is referred to as a final load training machine.

[0004] However, in such an endurance load training machine, the stiffening of the joint may be promoted, and the stretching function of the muscle may be lost, thereby narrowing the movable range of the joint. In other words, in the movement of the body, the force is transmitted from the central part to the terminal part, and in the end state of the body, the distal part does not continue to apply force, but the loss of power is the strength of the original physical function. That's it. Furthermore, in order to generate powerful energy in each joint, it is necessary to give flexibility and smoothness to the movement of the trunk (center part) of the body, which results in speed and balance.

[0005] However, according to the training using the final load training machine, the muscle group at the terminal end is more loaded than the muscle group at the root, and as the training is repeated, the hardening and hypertrophy of this part is caused. As a result, the range of motion of the joint is limited and the movement becomes dull. In addition, fatigue and accidents may be caused.

[0006] With respect to such final load training, initial load training has recently attracted attention. This refers to training in which the initial load in the initial state is large, the load decreases as the operation proceeds, and the final load is minimized. Hereinafter, a training machine in which the initial load in the initial state of the operation is maximum and the final load in the final state is minimum is referred to as an initial load training machine.

[0007] According to the initial motion load training, the root generates force and speed in the initial motion, and the force is smoothly transmitted to the distal end, so that the performance of the body is improved. In addition, since the speed of the initial operation is given by overcoming the load of the initial operation, the flexibility and elasticity in the movable range of the central part of the body can be increased. The above explanation is based on "New Training Revolution" (author Hiroshi Koyama) published by Kodansha Co., Ltd. on September 12, 1994.

SUMMARY OF THE INVENTION An object of the present invention is to provide a training machine (training device) suitable for initial load training. Another object of the present invention is to provide a training machine in which the initial load can be easily adjusted.

[0009]

According to the present invention, a weight is hung on the other end of an arm which is rotatably mounted with its end as a fulcrum. It is configured to be rotated so as to be raised by a trainer through the intermediary.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a base, to which a pair of upright bars 2 standing almost in the middle thereof is fixed, and a pulley 4 is rotatably mounted on a shaft 3 extending over the tips of both upright bars 2. An arm 5 has a base end 6 near the center of the base 1 and is rotatably supported between the upright bars 2. Therefore, the arm 5 is rotatable about the base end 6.

A weight receiver 7 is fixed to the distal end side of the arm 5, and the weight receiver 7 is inserted from the distal end of the arm 5 and receives the suspended weight 8. 9
Is a receiving frame for receiving the arm 5 so that the arm 5 does not approach a horizontal state beyond a predetermined angle. A pulley 10 is rotatably mounted on the arm 5 by a frame 11 at an arbitrary position between a base end 6 and a weight receiver 7.

12 is a rope (for example, a wire rope)
One end is located at a position slightly below the pulley 4 and is fixed to a frame (not shown) that straddles both upright bars 2, and the other end surrounds the pulley 10 and changes direction. The pulley 4 is pulled out to the rear side of the base 1 after being put together.

[0013] Between the tip of the upright bar 2 and the tip of the base 1,
A pair of arc-shaped rails 13 is provided. The weight receiver 7 straddles both rails 13, and legs 14 provided on the lower surface of the weight receiver 7 engage with side surfaces of the rails 13 facing each other. As a result, when the arm 5 rotates as described later, the lateral swing of the arm 5 is prevented.

Behind the base 1, an inclined seat 15 is integrally attached to the base 1. 16 is a stool 1
Legs 17 for maintaining the tilted state of the train 4 are footrests 17 for receiving the tips of the feet of the trainer 18 sitting on the stool 14 with the feet extended, and are fixed to the base 1 in an upright state. A grip bar 19 is attached to the tip of the rope 12 pulled out to the rear side of the base 1.

Next, a method of using the present apparatus will be described. As shown in the figure, the trainer 18 sits on the stool 15, extends his / her legs sufficiently, and places the tip of the trainer 18 on the footrest 17. In addition, the upper body is bent and the hand is sufficiently extended, and the grip bar 19 is gripped in this state. At this time, the arm 5 is received by the receiving frame 9 and is in a substantially horizontal state. At this time, it is assumed that the rope 12 is in a state without bending.

In this state, when the trainer 18 pulls the rope 12 by raising its upper body and extending it upward, or simultaneously or independently bending the elbow, the arm 5 Rotates about its base end 6 so as to rise from a horizontal state.

At the initial stage of the rotation of the arm 5, the gravity of the weight 8 acts in a substantially vertical direction.
In order to start the rotation of the rope, the rope 12 must be pulled strongly. That is, the initial load for training by rope pulling is sufficiently large.

As the rotation of the arm 5 continues and gradually approaches the standing state, the pulling force of the rope 12 required for the rotation of the arm 5 gradually decreases, and the arm 5 is almost standing in the final state. Then, the pulling force of the rope 12 is hardly necessary for the rotation of the arm 5. That is, there is almost no final load. As described above, the initial load in the initial state is large, the load is reduced as the operation proceeds, and training in which the final load is minimized can be executed.

Here, to adjust the initial load, the arm 5
What is necessary is just to increase or decrease the weight of the weight 8 to be hung on the tip of. Alternatively, the attachment position of the pulley 10 may be freely changed along the longitudinal direction of the arm 5. In any case, since the rotational moment of the arm 5 with respect to the base end 6 is changed, the initial load can be adjusted.

As shown in FIG.
If the pulley 10 is turned over, the displacement length of the pulley 10 with respect to the pulling length of the rope 12 and thus the arm 5
Can be reduced, so that the pulling length of the rope 12 can be lengthened even in the same rotation range of the arm 5.

In the configuration shown in the figure, the substantially vertical state of the arm 5 is set as the final position. However, the arm 5 may be moved so that the weight 8 can move horizontally further from this position. Good. For this purpose, a long hole may be provided at the base end 6 of the arm 5, and the arm 5 may be rotatably supported on the base 1 by an axis passing through the long hole.

[0022]

As described above, according to the present invention, a training apparatus suitable for initial load training can be easily configured, and the initial load can be easily adjusted.
