The present invention relates to a fitness bicycle using a hydraulic system, and more particularly to a fitness bicycle using a hydraulic system to increase the exercise effect that can be obtained by using a general bicycle more significantly.

In general, bicycles are mainly used as a means of transportation, but as the interest in health increases, more and more people use bicycles to promote their health.

However, because there are no bicycle paths to enjoy riding, it is very dangerous to ride a bicycle in a city with a lot of traffic.

Therefore, a lot of indoor bicycles have been devised and used to accommodate bicycle riding indoors.

However, when riding a bicycle outdoors, they do not feel bored because they drive while looking at the surrounding natural scenery, but conventional indoor bicycles have a very simple operating state, that is, they have a proper load in a fixed state. Since the exercise only pedaling, you feel tired of the exercise immediately, there was a problem that the exercise effect falls.

、 The present invention is a fitness bicycle using a hydraulic system for solving the problems of the conventional indoor bicycle as described above by using the hydraulic system to enable the exercise bike to move up and down during the bike riding exercise In the case of the rising and falling, the similar effect of running uphill and downhill on the actual outdoor road is the same, so that the exercise is not boring, the exercise duration is increased by increasing the exercise time, and the hydraulic pressure can be adjusted. Therefore, the internal pressure of the hydraulic system is an exercise load of the rotational movement of the lung moon, and the purpose is to provide a fitness bicycle using a hydraulic system that can be adjusted to the pressure suitable for each physical fitness to ride a bicycle.

(Not explanation code)

24, a supplementary oil container for replenishing oil lost in the cylinder rod; (6) a corrugated rubber tube made of corrugated layer; (10) a cover.

An embodiment of the present invention will be described in detail with reference to the accompanying drawings.

In the hydraulic system, when the motor rotates the pedal 46 with a constant rotational force, the pump 40 delivers oil as the rotation shaft 41 of the pump 40 rotates.

Some of the discharged oil is produced by opening the circulation opening and closing valve 23 slightly open (just before full lock) when the exercise bicycle is manufactured. Returning to 21), the rest of the fitness bicycle 1 starts to rise by the inflow of the upper cylinder chamber 8 through the on-off valve 19.

At this time, the rising speed is different if the amount of oil inlet in the upper cylinder chamber is changed according to the opening and closing control of the opening and closing valve 19.

Therefore, the ascending speed of the bicycle is determined by the opening and closing operation of the on-off valve 19.

As described above, the discharged oil is completed by the inflow of the upper cylinder chamber 8, and the oil can no longer go to the upper cylinder chamber 8, so that pressure in the pipe between the upper cylinder chamber 8 and the discharge pipe is increased. Will rise.

The pressure is the rotational pressure of the pump 40, and the load is applied to the bevel gears 43 and 43 'and the drive shaft 44 so that the internal pressure of the hydraulic pressure becomes the kinetic load of the pedal 46.

remind. The adjustment of the internal pressure causes the internal pressure of the delivery pipe 20.20 'to be discharged to the inlet pipe 21.21' through the circulation pipe 22 by adjusting the circulation opening / closing valve 23.

In other words, it goes back to a circular loop.

Thus, the internal pressure of the delivery pipe 20.20 'is adjusted.

That is, by adjusting the circulation opening and closing valve 23 to adjust the amount of oil to be discharged from the delivery pipe (20.20 ').

Therefore, if the exerciser adjusts the pressure corresponding to their physical fitness by the circulation opening and closing valve 23, the value becomes the exercise load.

Opening and closing control method of the circulation opening and closing valve 23 is as follows.

The circulation opening and closing lever 17 is in a state of being caught in the lower end hole of the opening and closing lever into which the other end screw rod 29 of the cable 16 connected to the circulation opening and closing lever 17 is in tension under the coil spring 18. By adjusting the opening and closing regulator 30, the circulation opening and closing valve 23 is adjusted to adjust the amount of oil circulated.

In other words. When the circulation opening and closing valve is adjusted to the open state by using the open / close controller 30, the internal pressure becomes the exercise load of the pedal as the pressure inside the cylinder chamber and the delivery pipe 20.20 'drops.

Therefore, it is possible to set the exercise load by operating the opening and closing controller 30, and when you want to descend the fitness bicycle elevated by the above-mentioned pedal rotation of the exerciser, the hydraulic pressure is not generated when the pedal 46 stops rotating, Due to the pressure of the weight of the exercise bike, the oil in the upper cylinder chamber (8) is lowered while moving to the lower cylinder (7) through the delivery pipe (20) and the circulation pipe (22).

However, if you want to descend during the movement of the operation of the open and close lever 27 configured in the handle 26, the open and close valve 27 and the circulation opening and closing lever 17 is connected to each other to the cable open and close the valve Thus, the oil discharged from the pump 40 moves to the circulation pipe 22 without any resistance, returns to the inlet pipe 21, and the inside of the discharge pipe 20.20 'becomes pressureless.

In addition, the pressure of the delivery pipe 20.20 'is an exercise load.

At this time, you feel the phenomenon of running downhill.

It is determined by the operation of the opening / closing lever using the thumb while the above-described descending movement is in progress.

In addition, when releasing the force applied to the open / close lever 27 by the thumb, the circulation opening / closing lever 17 under tension of the coil spring 18 is moved upward by the restoring force of the coil spring. 23 is blocked just before the safety lock.

The oil sent out from the hydraulic pump 40 by the circulation opening and closing valve is again introduced through the opening and closing valve 19 to the upper cylinder chamber 8, the exercise bike 1 is raised.

At this time, you feel the phenomenon of running uphill.

In this way, you can repeat the opening and closing lever repeatedly to descend and climb, so you can feel the effect similar to running the actual uphill downhill outdoors while riding a bicycle, and the exercise duration is not boring, Increases the exercise effect.

In addition, the exercise load by adjusting the exercise load according to their fitness will get a sufficient exercise effect.
