DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that the present invention may be easily implemented by those skilled in the art. In addition, in describing this invention, the same code | symbol is attached | subjected and the repeated description is abbreviate | omitted.

A treadmill equipped with an electromagnet according to the present invention will be described with reference to FIG. 1 or 2 or 3 or 4.

It is preferable that the sole of the athlete's shoe is a shoe sole made of iron pads in which iron powder is mixed with rubber or synthetic resin. Hereafter, it is called magnetic shoes.

1 is a configuration diagram of a chamber system having an electromagnet scaffold running machine according to the present invention;

As such, the chamber system attaches the electromagnet 41 under the tread 20 of the treadmill 9 and places the treadmill 9 into the spatially blocked chamber 100.

The chamber 100 and the treadmill 9 are easily attached by attaching wheels to the bottom.

The bottom of the magnetic shoe 60 is a magnetic material 70 when the rubber and magnetic powder or rubber and iron powder is mixed and then cured with an adhesive.

The rectangular slit is formed in the scaffold 20 to create a magnetic circuit passage for generating a magnetic force in which the electromagnet 41 and the magnetic shoes interact with each other, and this is called an air gap. On the footrest 20, the belt 10 which can adjust a running speed is rotating.

The magnetic material 70 of the magnetic shoe 60 and the electromagnet 41 beneath it generate magnetic forces that pull each other through the air gap 11, and the magnetic force is the core 40 according to the direction of the current flowing through the coil 50. The N or S pole is generated on the upper part of. The field in which the magnetic force is formed is called the magnetic field.

When the electromagnet of the footrest 20 becomes the N pole or the S pole, the magnetic shoes 60 are attracted.

Here, the control circuit 101 for adjusting the amount of current in the coil 50 of the electromagnet 41 is incorporated in the monitor 80 displaying the state of movement.

The current direction of the electromagnet controls the inversion circuit 180 to be a suction force acting in the direction of always pulling the shoe.

Here, the inversion control of the electromagnet is to reduce the suction force or facilitate the removal of the magnetized foreign substance due to the magnetization of the magnetic shoe by the electromagnet.

Then, the belt 10 is made of a material that does not interfere with the passage of the magnetic force line, so as not to weaken the interaction force. When the athlete is running, the magnetic shoe 60 acting on the footrest comes down with respect to the footrest 20 and goes up by adding force to overcome gravity.

Therefore, the electromagnet and the magnetic shoe when the shoe 60 is raised is a force that pulls each other to the load on the ankle of the athlete. That is, there is an advantage that the ankle exercise is not performed in the conventional treadmill.

 The chamber 100 with the nitrogen generator 90 is briefly described in the known art.

The composition ratio of air is approximately 20% oxygen and 80% nitrogen. When the amount of nitrogen in the air is increased, the amount of oxygen decreases. On the contrary, when the amount of nitrogen is reduced, the nitrogen generator 90 uses the effect of increasing the amount of oxygen.

 The chamber 100 has a completely enclosed space, the running machine 9 is stored inside the chamber 100 and the chamber 100 has a sliding door for containment. The chamber 100 includes a nitrogen generator 90 therein, and can control the supply of concentrated nitrogen by the nitrogen generator according to the momentum.

And the pressure regulator 91 was provided. Pressure regulating device Also briefly described in the known art, the pressure regulating device is composed of an air compressor (Compressor) for compressing air, a regulator (regulator) for adjusting the air pressure, a supply pipe for supplying air and the like.

The air pressure inside the chamber 100 may be adjusted to a low pressure or a high pressure by the pressure regulating device. In the present invention, when the pressure is adjusted to a low pressure, the exerciser may have the same conditions as the air pressure conditions in the high mountain region. The pressure of air decreases as it rises above the ground.

Therefore, the chamber shown in FIG. 1 implements a low pressure hypoxic chamber that simulates the same conditions as a running athlete wearing a sand bag on the ankle and running in a high mountain region with low air pressure and low oxygen.

2 is a plan view of the treadmill according to the present invention, in which the scaffold 20 has a rectangular slot.

The air gap 11 which cuts into the shape and which the upper and lower flows through is made, the magnetic force line passes, and the belt 10 rotates on the air gap 11.

Figure 3 illustrates the mounting structure of the electromagnet attached to the footrest of the treadmill according to the present invention

As a drawing for clarity, the structure of the electromagnet attached to the footrest 20 of the treadmill 9 is a side view of the mounting structure of the coil 50 that transmits current on the core 40, which is a material through which magnetic force passes. And wind in the horizontal axis direction. When current flows through the coil, the core becomes a magnet only for the duration of the current. That is, it becomes a magnet only when current flows. For convenience of description, the core 40 on which the coil 50 is wound is called an electromagnet 41.

The support 30 is used to fix the electromagnet 41 under the footrest 20. The support 30 is made of an insulating material that does not interfere with the flow of magnetic field lines. One side of the support 30 is fixed to the scaffold 20, and the other side is fixed to the electromagnet 41 so that the center line of the air gap 11 and the center line of the electromagnet 40 coincide with each other, and the air gap 11 as much as possible. Do not reduce the strength of the magnetic force close to.

On the footrest 20, the belt 10 for running rotates.

The difference signal is input to the error amplifier 150.

The input signal is amplified by the error amplifier 150 and then output to be input to the PWM pulse width modulator 160.

The output signal of the pulse width modulator is input to the driving stage 170 to turn on and off the transistor of the driving stage 170 to flow a current through the coil 50 to form an electromagnet. Changing the current direction of the drive stage 170 by using the signal of the forward and backward control circuit 180 is briefly described in the known art. The signal of 0 or 1 by the switch 2 (SW2) is the forward and backward control circuit 180. One of the two outputs is determined, and one output turns on either one of the two transistors of the drive stage. The two transistors of the driving stage 180 have a push-pull structure, when one is turned on, the other is turned off to change the direction of the current.

That is, if the current direction of the coil 50 is to be changed, when the forward reverse switch is turned on, a signal is generated from the forward reverse control circuit 180 to turn the transistor of the driving stage 180 on and off to change the current direction of the coil 50. Change.

When the voltage of the command command unit 120 is increased, the current flowing in the coil 50 increases in proportion to the voltage of the command command unit 120, thereby increasing the strength of the magnetic force. The intensity of the electromagnet may be controlled by the user using the program 110 switch or the variable volume 120 in the monitor 80.
