Patent Document 1 describes a handle that can be moved by the operation of an exerciser, a motion conversion mechanism that mutually converts the movement and rotational motion of the handle, and a motor in which the rotation axis rotates in conjunction with the movement of the handle by the motion conversion mechanism. Disclosed is a training machine control method including a control unit for controlling the torque of a motor, which sets a target value that changes depending on the acceleration, position, or time of the handle and changes the load of the handle. ..

In Patent Document 2, the user uses the exercise equipment based on the force given by the user to the exercise equipment in a series of exercises (exercise characteristics) and information such as the user's age and gender (attribute information). A method of controlling a training machine that can determine the load when exercising is disclosed.

According to the training machine of Patent Document 1, since the load can be applied by the motor, no weight is required and the training machine can be made compact. In addition, by controlling the motor, it is possible to give the user the same load as a device using weights, and it is also possible to change the load given to the user depending on the position of the handle on which the load is applied and the training time. It is said that. However, it has not been clarified how to control the specific load that can effectively improve the muscle strength of the user.

Patent Document 2 discloses a control method for determining a load based on a user's motion characteristics and attribute information, but there is a problem that it takes time and effort to input attribute information.

Therefore, in view of the above-mentioned problems, an object of the present invention is to provide a control method of a training machine that is easy to operate and can effectively improve the muscle strength of the user.

The present invention relates to a reciprocating means capable of linear or pivotal reciprocating movement, a load acquiring means for acquiring a load value given to the reciprocating means, and a load applying means for applying a load to the reciprocating means. It is a control method of a training machine equipped with
The load acquisition means acquires the load given to the fixed reciprocating means as a reference load in the forward direction.
The load applying means reciprocates a load equal to or less than the reference load as a forward load facing the reciprocating means in the forward direction when a load in the forward direction is applied to the reciprocating means. Applying the reciprocating means to the means, and then or before the reciprocating means, reciprocating the reciprocating means while applying a load larger than the reference load to the reciprocating means as a reciprocating load in the reciprocating direction of the reciprocating means. The above-mentioned problem was solved by the characteristic training machine control method.

According to the present invention, the load given to the fixed reciprocating means is acquired as a reference load in the forward direction, and the forward load facing the forward direction of the reciprocating means and the reciprocating of the reciprocating means Since the reaction load for the direction is determined, the load for training can be easily determined. In addition, since the load applying means reciprocates the reciprocating means while giving a reciprocating load in the reciprocating direction of the reciprocating means with a load larger than the reference load, when the user contracts the muscle of the target part or Since a relatively large load can be applied when stretching, the muscle strength of the user can be effectively improved.

Further, if a position sensor for detecting the base end and the end of the range in which the reciprocating means is moved is further provided, and the load applying means is controlled so as not to move the reciprocating means out of the range from the base end and the end. , The safety of the user can be ensured.

Further, each time the reciprocating means reciprocates, the forward load and the reciprocating load according to the position of the reciprocating means are set to be lower than the forward load and the reciprocating load at the time of the previous reciprocating movement. , The muscle strength of the user can be improved more effectively.

In addition, the forward load is gradually increased and then lowered as the reciprocating means moves in the forward direction, and the return load is gradually increased and then lowered as the reciprocating means moves in the reverse direction. With this configuration, the muscle strength of the user can be improved even more effectively.

The flowchart which shows the process in the control method of the training machine of one Embodiment of this invention. The figure which showed an example of the relationship of the reference load, the forward load, and the recovery load in the control method of FIG.

Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 and 2. However, the present invention is not limited to this embodiment.

The control method of the training machine of the present invention includes existing training machines equipped with reciprocating means capable of linear or pivotal reciprocating motion, such as chest press, leg press, shoulder press, triceps press, and hip addition. , Hip Abduction, Peck Fly, Rear Deltoid, Lateral Raise, Lat Pulldown, Seated Row, Arm Curl, Assist Chin Up, Leg Extension, Leg Curl, Line Greg Curl, Glute, Back Extension, Abdominal, Toso Rotation, It can be applied to car fleece and the like. In these training machines, the reciprocating means is a handle or handle that can be grasped by hand, a bar-shaped one that can hang shoulders, arms, or legs, or a plate-shaped one that can be pushed by a foot or the like. ..

In order to apply the present invention, it is necessary to acquire the value of the load given by the user and adjust the load given to the user. Therefore, in the training machine, the load is given to the reciprocating means. It is necessary to have a load acquisition means for acquiring the value of the load and a load applying means for applying a load to the reciprocating means. Specifically, a load is applied to the reciprocating means through a wire or a belt by a motor or a cylinder (including pneumatic and hydraulic pressure) or a combination of these and a brake mechanism, and a load is applied to the motor or the cylinder through the reciprocating means by a sensor. It is necessary to have a configuration to acquire the applied load.

Further, it is preferable that the training machine further includes a position sensor that detects the base end and the end of the range in which the reciprocating means is moved. The position sensor may be a known one such as a mechanical switch or an optical sensor. Since a training machine having the above configuration is already known, detailed description thereof will be omitted.

FIG. 1 is a flowchart showing a process in a control method of a training machine according to an embodiment of the present invention. When the user starts using the training machine, the reciprocating range determination process S10 is executed. In the reciprocating range determination process S10, the base end and the end of the range in which the reciprocating means is moved by the user are detected by the position sensor. At this time, it is preferable that no load is applied to the reciprocating means.

The base end and the end where the reciprocating means is moved can be detected when the reciprocating means is moved once, but the maximum value of the base end or the end when the reciprocating means is moved a plurality of times. , Minimum value, or average value. If the reciprocating means is controlled so as not to move out of the range from the base end or the end of the reciprocating means acquired in this way, the user can use the reciprocating means without the need for an assistant of the user to perform the training. Safety can be ensured. In the case of a training machine not provided with a position sensor, the reciprocating range determination process S10 is omitted.

When the reciprocating range determination process S10 is completed, the reference load determination process S12 is executed. In the reference load determination process S12, the load given to the fixed reciprocating means is acquired as the reference load in the forward movement direction. The acquired reference load value may be stored in a primary storage means such as a flash memory or a storage means such as a hard disk.

In the reference load determination process S12, the load given to the reciprocating means may be a load in the linear motion of the reciprocating means or a load in one direction or the other direction in which the reciprocating means is pivoted. For example, in the case of a chest press, the user may push the reciprocating means (a direction away from his / her chest) or pull the reciprocating means (a direction closer to his / her chest). Regardless of the load in either one direction or the other direction, this load is acquired as a reference load in the forward direction. The reference load is preferably the user's maximum voluntary contraction. In this case, in the training machine to which the control method of the present invention is applied, the muscle strength of the user can be trained most effectively.

After the reference load is acquired by the reference load determination process S12, the forward load application process S14 is executed. The forward load applying process S14 is preferably started from a state in which the reciprocating means is at the base end or the end end. In the forward load applying process S14, the load applied means sets a load equal to or less than the reference load as a forward load facing the forward load of the reciprocating means when a load in the forward direction is applied to the reciprocating means. It is given to the reciprocating means.

The reciprocating load applying process S16 is executed from a predetermined position, a terminal position, or a base end position of the reciprocating means. In the reciprocating load applying process S16, the reciprocating means is reciprocated while applying a load larger than the reference load to the reciprocating means as a reciprocating load in the reciprocating direction of the reciprocating means. In this way, the reciprocating means reactivates while a load larger than the reference load is applied, so the user can efficiently contract the eccentric contraction of the muscle to be trained by exerting force against this. It can be realized well. According to the present invention, since a load is applied to both the forward and backward directions of the reciprocating means, strength training can be performed even in a weightless space.

Here, the speed at which the reciprocating means is restored may be adjusted in consideration of the safety of the user. In the first round trip of the reciprocating means, the reciprocating load applying process S16 is usually executed after the outgoing load applying process S14, but the reciprocating load applying process S16 may be executed first. good.

As described above, according to the control method of the training machine of the present invention, the load given to the fixed reciprocating means is acquired as the reference load in the reciprocating direction, and the load is opposed to the reciprocating means in the forward direction. Since it is possible to determine the forward load to be performed and the recovery load in the recovery direction of the reciprocating means, the operation of determining the load for training is simple.

In the forward load applying process S14 and the reciprocating load applying process S16, the value of the load applied to the reciprocating means may be constant, but the value of the load is changed according to the position of the reciprocating means. May be good. Therefore, with reference to FIG. 2, an example of the load applied to the reciprocating means by the forward load applying process S14 and the reciprocating load applying process S16 will be specifically described below.

Further, each time the reciprocating means reciprocates, the forward load and the reciprocating load according to the position of the reciprocating means are set to be lower than the forward load and the reciprocating load at the time of the previous reciprocating movement. Is good. According to this configuration, the user can easily reciprocate a plurality of sets of the reciprocating means, so that the muscle strength of the user can be further effectively improved.

In FIG. 2, the horizontal axis p is the position of the reciprocating means, and for convenience, the base end of the reciprocating means is represented as 0 and the end is represented as 1. The vertical axis KL is a load value, the unit is kilogram-force (kgf), and the reference load acquired by the reference load determination process S12 is represented as Fmax. Fmax * 2 is a line showing a value twice that of Fmax. In the following description, the value of Fmax is not the value of the actual load, but Fmax = 1 for convenience. As described above, the reference load is preferably the maximum voluntary contraction of the user, but this may be adjusted depending on the physical condition of the user and the like.

In the control method shown in FIG. 2, in the forward load applying process S14, the forward load FS is gradually increased and then decreased as the reciprocating means moves in the forward direction. Specifically, when the position of the reciprocating means is 0 ≦ p <0.26, the forward load FS increases according to the function of KL = 1.89p + 0.27. Next, when the position of the reciprocating means is 0.26 ≦ p <0.71, the forward load FS increases according to the function of KL = 0.53p + 0.62, and the position of the reciprocating means is 0.71. When ≦ p <1.0, the forward load FS decreases according to the function of KL = −1.04p + 1.74. When the value of the position p of the reciprocating means is 0.71, the value of the forward load FS is equal to Kmax.

Further, in the reciprocating load applying process S16, the reciprocating load SS is gradually increased and then decreased as the reciprocating means moves in the reciprocating direction. Specifically, when the reciprocating means is 0 ≦ p <0.71, the reciprocating load SS increases according to the function of KL = 0.05p + 1.49. Then, when the reciprocating means is 0.71 ≦ p ≦ 1.0, the reciprocating load SS is reduced according to the function of KL = −1.06p + 2.28.

As described above, the load applied to the reciprocating means in the forward load applying process S14 and the reciprocating load applying process S16 may be changed by gradually increasing the load and then decreasing the load as the reciprocating means moves. With this configuration, the muscle strength of the user can be improved even more effectively. The forward load applying process S14 and the reciprocating load applying process S16 may have different load curves from the base end to the end of the reciprocating means, and the curve can be determined by the control method of the training machine of the present invention. It can be modified by the built-in training machine, i.e., to effectively train the muscles being trained.

According to the present invention described above, it is possible to provide a control method of a training machine that is easy to operate and can effectively improve the muscle strength of the user.
