Referring to Figure 5 attached to the operation process according to an embodiment of the present invention configured as described above are as follows.

5 is a flowchart illustrating an operation control process of a weight training exercise apparatus according to the first embodiment of the present invention.

As shown in FIG. 5, first, the movement range and the movement speed of the load are set in advance through the display / operation means 600 before the start of the exercise (Step 100). Here, the movement speed of the load means the movement speed of the piston 310. For example, as shown in FIG. 6, when the 'OUT' switch 610 is adjusted, the steel wire 120 is pulled toward the exerciser. In the central direction of movement) is to set the opening size of the resistance adjustment hole 360 in the hydraulic control valve 340 of the cylinder 300, the 'IN' switch 620 is adjusted to the steel wire 120 into the exercise equipment The driving speed of the hydraulic pump 500 is set in the pulling operation (eccentric motion direction).

In addition, the movement range of the load means the movement range of the piston 310, when the 'OUT' button 630 is pressed, the hydraulic pressure control valve 340 is fully opened by opening the resistance adjustment hole 360 to the outermost The exercise handle 700 can be pulled to a desired position, and after the movement of the exercise handle 700, pressing the 'OUT' button 630 again is set to the lowered position. After pressing the 'IN' button 640 the hydraulic control valve 340 to block the resistance adjustment hole 360, the hydraulic pump 500 starts to drive and slowly pull the steel wire 120, When the position is reached, pressing the 'IN' button 640 again sets the rising position.

After the setting is completed, when the exerciser presses the start button 650 and then pulls the exercise handle 700, the position detecting sensor 400 detects this, and thus the motion control means (not shown) moves in the direction of movement. (Step 110, Step 120, Step 130). That is, according to the scale change of the positioner 320 detected by the position detecting sensor 400, the motion control means determines whether it is an oriented or eccentric movement direction.

Thereafter, the driving of the hydraulic pump 500 is controlled on / off according to the movement direction detected in the steps (Step 120 and Step 130) (Step 140 and Step 150).

That is, when the determined movement direction is the central movement direction, as shown in FIGS. 7 and 8, the driving of the hydraulic pump 500 is turned off, and when the detected movement direction is the eccentric movement direction, the hydraulic pump. Drive 500.

At this time, the motion control means flows flowing into the cylinder 300 from the storage tank 200 through the first flow path 210 by controlling the hydraulic control valve 340 when the hydraulic pump 500 is driven off. The resistance adjusting hole 360 is opened to maintain the moving range and the movement speed of the piston 310 in which the amount of the liquid is set (Step 140), through which the force of the exerciser pulls more than the hydraulic pressure inside the cylinder 310. As soon as the piston 310 increases, the piston 310 rises in the center direction so that the athlete moves at the maximum strength from the start of the exercise.

If the hydraulic pump 500 is driven on, the amount of fluid flowing into the storage tank 200 from the inside of the cylinder 300 through the first flow path 210 is controlled by controlling the hydraulic control valve 340. Closing the resistance adjusting hole 360 to maintain the set movement range and the movement speed of the piston 310 and at the same time by the force of the flow liquid introduced by the hydraulic pump 500 through the second flow path 220 ( 310 is lowered (Step 150). As a result, the exerciser is opposed to the drag force, thereby improving the exercise effect.

In addition, the display unit 660 of the display / manipulating means 600 displays the value detected by the hydraulic sensor 330 in the cylinder 300 at each position detected by the position sensor 400 while the exerciser is exercising. The pressure is displayed in graphs and numbers in real time.

Subsequently, when the exerciser repeatedly maintains the movement in the center and eccentric motion directions and presses the end button 670, the hydraulic control valve 340 blocks the resistance adjustment hole 360, and the hydraulic pump 500 Drive and slowly pull the steel wire 120 to position the movement knob 700 in the top position and stops (Step 160, Step 170).

In the present invention, as shown in Figs. 9 and 10 in order to enlarge the variable width of the movement range of the movement handle 700, that is, the movement range of the piston 310 a predetermined distance and step inside the case 100 And a plurality of second steel wire pulleys 810a to 810d connected to each other through steel wires 121 mounted on an outer circumferential surface of the plurality of second steel wire pulleys 810a to 810d.
