The lifting unit 130 includes a lifting rail 132 inserted into the guide 116, a lifting shaft 138 for transferring the lifting rail 132 up and down, and a lifting motor 144 for rotating the feeding shaft 138. do.

The lifting rail 132 is formed to be transported up and down along the guide 116. A vertical long groove 134 (see FIG. 3) is formed on one side of the elevating rail 132 so that the contacts of the elevating control sensor 118a and the descending control sensor 118b protruding toward the guide 116 are fitted. The female screw hole 136 is formed on the lower surface. On the other hand, the feed shaft 138 is provided with a first pulley (140a) at the bottom and vertically extends upwardly to penetrate the female screw hole 136 and extends to the inside of the lifting rail (132). On the outer circumferential surface of the feed shaft 138, a male screw 142 corresponding to the female screw hole 136 is formed. On the other hand, the lifting motor 144 is disposed on the upper surface of the resttable 120. The elevating rotation shaft 146 of the elevating motor 144 extends through the upper surface of the arbor 120 and a second pulley 140b is formed at the end thereof. At this time, the rotation belt 148 connecting the first pulley 140a and the second pulley 140b is disposed on the first pulley 140a and the second pulley 140b. The rotating unit 150 is disposed above the lifting rails 132 of the lifting unit 130 formed as described above.

The rotating unit 150 includes a first bracket 152, a second bracket 154, an angle conversion gear 158, and a rotation motor 168. First, the first bracket 152 has a rectangular box shape of the top and bottom open and one side is coupled to the upper side adjacent to one side of the lifting rail 132 by the fastening bolt (V1). The second bracket 154 has a shape in which one side is open to accommodate a portion of the other side and both sides of the first bracket 152. The second bracket 154 and the first bracket 152 is coupled by the hinge 156. In this way, the angle conversion gear 158 and the rotation motor 166 are disposed on the second bracket 154 coupled to the first bracket 152.

The angle conversion gear 158 is rotatably disposed on the other side of the second bracket 154. A locking projection 160 is formed on the circumferential surface of the angle conversion gear 158, and one side of the angle conversion gear 158 rotates together with the angle conversion gear 158 while the rear fastening bolt V2 of the monitor M is rotated. Coupling plate 162 is disposed to be coupled by. On the other hand, the horizontal control sensor 164a and the vertical control sensor 164b are fixedly disposed on the second bracket 154 on both sides of the angle conversion gear 158. The horizontal control sensor 164a and the vertical control sensor 164b interfere with the locking projection 160 that rotates together with the angle conversion gear 158 to allow the angle change gear 158 to rotate only 90 ° C. On the other hand, the rotary motor 166 is disposed horizontally below the second bracket (154). The rotating shaft 168 of the rotating motor 166 disposed in this way extends to the other side of the second bracket 154 and has a driving gear that engages with the angle conversion gear 158 at the end to rotate the angle conversion gear 158. 170 is formed.

The following briefly describes the operating state of the stand apparatus 100 of the monitor configured as described above.

4a and 4b is a view showing a state in which the monitor mounted on the stand apparatus according to the present invention is raised and lowered. Referring to FIG. 4A, the user first rotates the lifting motor 144 by operating a predetermined controller (not shown) in order to transport the monitor M to an optimal height. When the lifting motor 144 rotates forward, the lifting shaft 146, the second pulley 140b, and the first pulley 140a and the feed shaft 138 connected by the rotation belt 148 rotate, and as a result, The lifting rails 132 are transferred upward. When the lifting rail 132 is raised in this way, the rotating unit 150 and the monitor M which are fastened to the lifting rail 132 are raised along the lifting rail 132.

At this time, when the lifting rail 132 is transported to the maximum height, the lower end of the long groove 134 is in close contact with the contact of the lifting control sensor 118a. When the lift control sensor 118a operates as described above, the lift control sensor 118a sends a signal to the controller, and the controller stops the rotation of the lift motor 144. When the rotation of the lifting motor 144 is stopped by the lifting control sensor 118a as described above, the control unit operates the rotating unit 150.

5a and 5b is a view showing a state in which the monitor mounted to the stand device according to the present invention is rotated. Referring to the operating state of the rotating unit 150, the control unit rotates the rotating motor 166 of the rotating unit 150 at the same time the lifting motor 144 is stopped. When the rotation motor 166 is rotated forward, the driving motor 170 connected to the rotation motor 166 rotates, and the angle conversion gear 158 and the monitor M coupled with the driving motor 170 are coupled to each other. The plate 162 is rotated to one side. At this time, as the angle conversion gear 158 rotates, the locking projection 160 formed on the angle conversion gear 158 rotates together, and the locking projection 160 is in close contact with the horizontal control sensor 164a. The locking protrusion 160 is in close contact with the horizontal control sensor 164a, and the control unit stops the rotation of the rotating motor 166. As a result, the monitor M is arranged horizontally.

On the other hand, in order to arrange the monitor M again vertically (see FIG. 4B), the user operates the control unit to reversely rotate the rotating motor 166 of the rotating unit 150. When the rotation motor 166 is reversely rotated as described above, the drive gear 170 rotates the angle conversion gear 158 to the other side. When the angle conversion gear 158 rotates as described above, the locking protrusion 160 that is in close contact with the horizontal control sensor 164a also rotates to be in close contact with the vertical control sensor 164b. As a result, the monitor M is again placed vertically.

In addition, in order to lower the monitor M to a certain height, the control unit operates the lifting motor 144 to reverse rotation. When the lifting motor 144 reversely rotates, the lifting shaft 146, the second pulley 140b, and the first pulley 140a and the feeding shaft 138 connected by the rotating belt 148 rotate, and as a result, The lifting rails 132 are transported downward.

At this time, when the lifting rail 132 is transported to a maximum low, the upper end of the long groove 134 is in close contact with the contact of the lowering control sensor 118a. As such, the control unit stops the rotation of the lifting motor 144 to operate the lowering control sensor 118a.

In the above description, only the lifting unit 130 is transported to the maximum height, but the user can arbitrarily adjust the appropriate height.

As described above, the stand 100 of the monitor to enable automatic lifting and rotating according to the present invention is the upper side and by the rotation of the feed shaft 138 and the feed shaft 138 connected to the lifting motor 144 The monitor M is provided by an elevating rail 132 that is transported downward and an angle conversion gear 158 that vertically or horizontally arranges the monitor M mounted by the rotary motor 166. It can automatically adjust to the desired height and has the advantage of selectively rotating the monitor (M) vertically and horizontally.

Although described above with reference to a preferred embodiment of the present invention, those skilled in the art will be able to variously modify and change the present invention without departing from the spirit and scope of the present invention described in the utility model registration claims. It will be appreciated.
