A driving means 50 is installed in the vertical guide bar 40, and a lift table 41 is lifted and lowered by the rotational force of the drive means 50, and the first support means 100 is installed on the lift table 41. do.

For example, as shown in FIG. 4, the first support means 100 includes a first fixed rail 110, a first bearing 120, and a second movable rail 130.

More specifically, as shown in FIG. 1D, the fixing pedestal 10 is vertically integrally installed with the first fixing rail 110, and a fixing groove 111 is formed at an upper portion thereof.

As shown in FIG. 2, the driving means 50 includes a stationary motor 51 and a second gear 53 which is engaged with the first gear 52 formed on the motor shaft and vertically lifted. As shown in FIG. 3, a first pulley 54 installed at a motor shaft, a second pulley 55 corresponding to the first pulley 54 and installed at one end of the vertical guide bar 40, and It consists of a belt 56 is installed to be linked to the first and second pulleys 54, 55.

As shown in FIG. 2, a first bearing 120 is installed inside the first fixing rail 110 to smoothly vertically lift the first moving rail 130.

At this time, the automatic stretching means 140 is installed to restrict the vertical movement of the first moving rail 130 from the first fixed rail 110, the automatic stretching means 140 is shown in FIG. As shown in FIG. 1 or FIG. 4, a switch unit 141, a power supply unit 143 for supplying power to the control unit 142 by the operation of the switch 141, and from the power supply unit 141. The driving motor 144 is supplied with power, and the coil spring plate 145 for elevating the movable rail 130 from the fixed rail 110 by the operation of the drive motor 144.

On the other hand, the drive motor 144 is a forward and reverse motor that is in reverse rotation.

One end of the leaf spring 145 is fixed to one end of the moving rail 130.

As shown in FIG. 1D or FIG. 4, the second supporting means 200 includes a second fixing rail 210 which is rotated by using the pivot shaft P as a supporting point at one end of the first fixing rail 110. The second movable rail 230 is smoothly lifted horizontally by the sliding operation of the second bearing 220 installed inside the second fixing rail 210 and the monitor 10 is rotatably installed at one end thereof. In addition, the second fixing rail 210 is configured to include an elastic piece 240 for restricting the advance or retreat horizontally.

Rotating support 300 is one end is rotatably installed on the second fixed rail 210, the rotating shaft (P1) and the other end is fixed to the fixing groove 111 formed in the first fixed rail 110, the second fixed rail ( It is formed to support the 210 and the monitor 20.

The folding means 400 is configured to push out the pivot support 300 from the fixing groove 111 of the first fixing rail 110. The folding means 400 will be described in more detail, the release piece 410 rotatably supported on one side of the first moving rail 130 and the push button 420 integrally installed at one end of the understanding piece 410. ), A flow preventing part 430 for preventing the flow when the rotation support 300 is folded in the upper portion, one end is installed on the second fixing rail 210 and the other end is installed on the rotation support 300, the elastic force It is composed of an elastic member 440 to be folded.

Therefore, when the user operates the switch 141, the monitor elevating device 1 configured as described above drives the driving means 50 to elevate the monitor 20 structure installed on the platform as shown in FIG. 1B.

Next, as described above, when the raised monitor 20 is flipped in the direction of arrow a of FIG. 1D, the pivoting support 300 repels the elastic force of the elastic member 440 on the second fixing rail 210, or FIG. As shown in FIG. 1D, the monitor 20 is fixed by being fixed to the fixing groove 111 of the first fixing rail 110.

When the user "on" the switch 141 to fit the body in the above state, the control unit 142 supplied with power from the power supply unit 143 receives the "on" signal to the drive motor 144 in the forward direction When driving to, the plate spring 145 installed on one side of the drive motor 144 is released while the second moving rail 130 is raised in the direction of the arrow "b" of FIG.

As described above, when the first moving rail 130 is adjusted to fit the body and the monitor 20 is pulled in the direction of arrow c of FIG. 1d to adjust the distance to the user's eyes, the second moving rail 230 is moved.
