Description

A running machine that uses weight and power as a power source {A RUNNING MACHINE USING WEIGHT TREADING FORCE AS A POWER SOURCE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manual treadmill that drives a running belt by using a power (stepping force) of a stepping step due to the weight of a person using no electricity.

In more detail, the running unit for walking using the running belt is separated into left and right independent running units driven separately by the left and right feet, and the left side or the front side is inclined upwardly by the left or right hydraulic cylinder. The foot of the right independent running part is rotated downward by the weight of the left or right foot to position the front side horizontally and at the same time increasing the rotational angular velocity to convert the running belt into the backward moving power source, so that the walking of the left or right foot is provided. The hydraulic pressure pressurized by the weight of the foot on the left or right side of the independent running unit operates the right or left hydraulic cylinder of the right or left side of the independent running unit to rotate the front side of the foot up inclined upward and downwards to the weight of the right or left foot. Rotate to position horizontally and at the same time It is economical and walking movement by using the left and right foot power as the power source without power consumption by providing the continuous walking movement of the person by the repetition of providing the walking of the right or left foot by increasing the speed to the backward movement power source of the running belt. The present invention relates to a treadmill that is powered by a weight effort that can maximize and provide effective exercise.

In general, the walking exercise effect improves breathing rate, increases oxygen intake, increases blood circulation, increases cardiac output, decreases heart rate, increases high-density lipid protein (HDL: good cholesterol), relieves obesity and improves hyperlipidemia. It is known as a representative aerobic exercise to maintain high blood pressure and diabetes, prevent aging and maintain bone density.

Therefore, a treadmill that can exercise walking indoors has been disclosed with various technologies.

These treadmills can be used as a typical indoor exercise equipment in a narrow space because the walking effect of running on the plain or walking in a narrow space can be achieved by walking on a running belt of a caterpillar wheel driven by an electric motor. It is widely used in general households.

Looking at the general structure of such a treadmill with reference to Figure 1,

It is installed between the running part 10 which forms a space where a person can walk and run, and the two vertical frames 21 which are erected with a predetermined slope in front of the running part to drive the running part 10. It is comprised by the control part 20 to control.

The running part 10 is assembled with the front and rear belt rollers 12 and 13 so as to be rotatable at intervals before and after the side frame 11 of both sides, and the rear of the front roller roller 12 The running belt 14 is wound around the belt roller 13 in the form of an endless track, and the belt pulley 18 is assembled to the front belt roller 12 so that the front belt roller 12 The power is transmitted from the motor pulley 19 of the motor 16 to the belt 15 to rotate to move the running belt 14 backward, and both sides of the side frame 11 are supported between the two side frames 11. In this state, the footrest 17 is assembled to provide deflection and cushioning of the running belt 14.

However, such a conventional electric treadmill has the following disadvantages.

First, there is a disadvantage in that the running cost of the running belt 14 is driven by the electric motor 16, the operation cost according to the electricity consumption.

Second, when the electric motor 16 is broken according to the use, there is a disadvantage in that the manufacturing cost is high as well as the replacement cost.

Third, the load of the electric motor is increased by walking a person carrying weight on the running belt 14 which is rotated and rotated by the electric motor 16. Since the electric consumption of the motor 16 is increased, there is an uneconomical disadvantage.

That is, the electric motor 16 receives a load by weighting the running belt 14 in which the weight of the person moves backwards in a vertical direction while the human feet alternately step on the running belt 14 moving backward by the electric force. The stress on the running belt 14, which is a vertical load due to the human weight, is forced to move at a moment. As the usage period becomes longer, tension adjustment by the deformation of the running belt 14 is required, and the life is shortened. It is pointed out as a factor.

Fourth, by repeating the process of opening the running belt 14 backward moving by the electric motor 16 backwards to move the distance between the feet to a certain distance can only provide a simple walking motion effect within a predetermined time Does not provide effective aerobic exercise.

Accordingly, in the present invention, the left or right independent running unit, which is inclined upwardly by the left or right hydraulic cylinder among the left and right independent running units that are independently driven, is rotated downward by the weight of the left or right foot, so that the front side is rotated. At the same time, the rotational angular velocity is increased and converted to the backward movement power source of the running belt to provide walking of the left or right foot, and the hydraulic pressure pressurized by the weight step force applied to the footrest of the left or right independent running part is right. Alternatively, by operating the right or left hydraulic cylinder of the left independent running part, the front side of the footrest is rotated upwardly and rotated downward by the weight of the right or left foot, and the horizontal position is increased while the rotational angular velocity is increased to move backward of the running belt. To the power source and to the right or left foot By repeating that line to provide provide a continuous pedestrian movement of people and aims to provide a walking exercise without electricity consumption.

In addition, an object of the present invention is to ensure the economical efficiency without the need for electricity consumption, and to minimize the deformation of the running belt even in long-term use to ensure a long life.

In addition, an object of the present invention is to provide an effective walking exercise is provided by driving the running belt with the weight of a person's weight, to provide the maximum amount of exercise even in a short time.

That is, the present invention provides an effective aerobic exercise by converting the weight of the person's weight into a power source of the running belt and generating the power generated by the power of the person by repeated walking.

The treadmill according to the present invention as a power source has the following effects.

First, there is an advantage that the cost of operation is low because no electricity consumption.

Second, there is an advantage that the manufacturing cost is low because no electric motor is required.

Third, there is an advantage that the deformation of the running belt is minimized even in long-term use to provide life extension.

Fourth, there is an advantage of maximizing the amount of exercise of walking exercise using the power of the running belt as a power source of power, and provides an effective aerobic exercise within a predetermined time.

The key feature of the present invention is to convert the power applied by the user's weight without the consumption of electricity to the power source of the backward movement of the running belt.
