In this case, a separate rope member 186 connected to the vertical sliding member 184 also rotates together with the vertical sliding member 184 to support the vertical sliding member 184.

As such, the upper and lower sliding members 184 move upwards, and approach the plurality of first and second limit switches 173 and 174 formed on the upper support 112 to move the switch within a predetermined distance so that the switch is no longer operated. It will not rise.

On the other hand, if you want to descend is different from the above-mentioned ascending operation, if descending, as mentioned above, the method used in the conventional method of first ascending and then descending, and second, immediately descending There are ways to hold down the down operation switch, but this method has an uncomfortable problem, respectively, as described above, the present invention is to be able to immediately descend if you press the operation switch once in one-touch method.

Referring to the operation of the control means 130 shown in FIG. 6 in detail, when the user presses the rising switch (1391), which is the up button after turning on the power (not shown), the magnetic relay 1310 Next, the magnetic relay contact point 1312, which is an A contact point of the magnetic relay 1310, is driven, and then the motor 150 is operated. Thus, the motor 150 is operated so that the lower support is performed. The member 120 is raised.

On the other hand, if the user wants to descend after a certain height ascending, the first relay 1320, which is an auxiliary relay, is activated when the rising and lowering switch (1392) is pressed, and then a contact point a of the first relay 1320 is used. The first relay contact point 1322 is connected at the same time, the magnetic relay 1310 is operated to operate the motor 150, and at the same time the first relay contact point (1323) is connected to the other a contact point The first timer 1370 operates to maintain the lower support member 120 for a predetermined time, for example, typically within 2 to 6 seconds.

After a predetermined time (about 2 seconds to 6 seconds) has elapsed as described above, the first timer non-contact 1374, which is a non-contact point connected to the lift switch 1391, is blocked, and eventually the rise is performed. The switch 1391 is cut off to stop the ascending operation. Then, as the first timer 1370 operates, the solenoid 1137, which is an A contact of the first timer 1370, is turned on. The valve 1350 and the unlocking solenoid 260 operate to perform the lowering operation.

That is, after a predetermined time elapses after the first relay contact point 1323 is connected and the first timer 1370 operates, the first timer non-contact point 1374 that is in the upward motion is blocked and the first timer is closed. The A contact 1372 is operated to perform the lowering operation.

When the lower switch 1394, which is another button, is pressed, the solenoid valve 1350 and the unlocking solenoid 260 are operated to descend, but in this case, the lower switch 1394 is continuously pressed. There is a disadvantage that the lowering is made only when pressed.

On the other hand, when the user presses the one-touch lowering switch 1393, which is another button to descend, the second relay 1330 and the second timer 1340 are operated to be connected, and then the contact point of the second relay 1330 Since the second relay contact point 1332 is operated, the connection operation is continuously performed even if the user does not press the one-touch lowering switch 1393 any more.

In addition, since the second relay contact point 1333 is connected to drive the solenoid valve 1350 and the unlocking solenoid 260, a lowering operation of lowering the lower support member 120 is performed.

On the other hand, as the second timer 1340 operates, the second timer non-contact point 1342, which is a non-contact point of the second timer 1340, passes after a predetermined time, and preferably adjusts to about 30 seconds to 1 minute. The operation of the one-touch lowering switch 1393 by being turned off (OFF) is that the lower support member 120 is completely lowered to the floor and blocked after a while.

The lift device operated in the one-touch method of the present invention configured as described above can be easily lowered while the user presses the switch in one touch only once if one wants to lower the vehicle guided to the vehicle lift. Therefore, to provide a one-touch lift device that can bring convenience and efficiency of work.
