Hereinafter, a use example of the raising and lowering device of the display device according to an embodiment of the present invention will be described with reference to the accompanying drawings.

As shown in FIGS. 8 to 10, the body 52 having the display device 55 such as an LCD monitor fixed to the fixing plate 56 of the above-mentioned lifting plate 57 is fixed inside the table. Thereafter, the display device 55 may be lifted with respect to the top plate due to the operation of the switch 61, or the display device 55 may be lowered to be accommodated in the table.

A) The process of lifting the display apparatus to the upper surface of the table in order to use the display apparatus will be described with reference to the accompanying drawings.

3, 4 (b), 5 (b), 6, 7 (a), 8 and 10, the display device 55 connected to the computer 80 (PC) In this case, the display device 55 can be lifted and placed on the upper surface of the table through the opening 75 formed in the upper plate such as a table.

When the first button 61a of the switch 61 is operated by the user, the first drive motor 53 is driven in the forward direction by the control signal output from the control means 62. The drive belt 54 mounted to the driven pulley 77 fixed to the first drive motor 53 and the driven pulley 78 fixed to the body 52 is in orbital motion.

Therefore, the lifting and lowering plate 57 fixed integrally to the driving belt 54 is supported by the left and right guides 76 and moved to the upper position. At this time, the door 51 mounted to the opening 50 is opened by the door opening and closing means interlocked with the rising and lowering plate 57.

That is, as the pressing member 67 of the raising and lowering plate 57 is separated from the latching jaw 70 of the lever 71 due to the rising and lowering of the lowering plate 57, the elastic force of the elastic member 74 ( By pulling force), the lever 71 fixed to the side plate 60 inside the body 52 is pulled up toward the door 51. At this time, since the latching jaw 70 of the lever 71 is moved to the upper end of the slot 72 of the bracket 73 fixed to the side plate 60, the lever 71 is no longer raised.

Therefore, when the lever 71 is moved toward the door 51, the pivot plate 69, which is rotatably fixed to the upper end of the lever 71, is rotated counterclockwise around its fixing pin. As a result, the pressing force of the rotating plate 69 for pressing the door 51 is released, so that the door 51 is rotated counterclockwise around the hinge portion and opened from the opening 50.

In this case, the door 51 may be opened from the opening 50 by its own weight when the pressing force of the pivot plate 69 is released by the lever 71 as the door 51 is formed as an eccentric body.

On the other hand, when the lifting and lowering plate 57 is moved to the upper position due to the operation of the first button (61a) (that means, the lifting and lowering plate 57 is moved to the position to close the opening 50), the body (52) Due to the mutual contact between the first sensing terminal 63 formed in the upper side of the inside and the contact member 64 fixed to the lifting and lowering plate 57 is moved to the set upper position of the lifting and lowering plate 57 To detect that.

Accordingly, the driving of the first driving motor 53 is stopped by inputting the detection signal from the first sensing terminal 63 into the control means 62 (PCB). In other words, the lifting and lowering plate 57 is moved to a set upper position (that is, the position where the rising and lowering plate 57 rises to close the opening 50) and stops. At this time, the fixing plate 56 is maintained in the vertical direction with respect to the rising and lowering plate 57.

As described above, when the lifting and lowering plate 57 is moved to the upper position set along the driving belt 54, as shown in FIGS. 6 and 7 (a and b), the lifting and lowering plate 57 Tilt the fixed plate 56 to which the display device 55 is fixed by the second driving means mounted to the user by an angle set toward the user (that the user can tilt the display device 55 by an angle that can be easily monitored). telling).

2) If the display device is not used, the process of lowering the display device and storing it inside the table will be described with reference to the accompanying drawings.

2, 4 (a), 5 (a), 7 (a) and 9, the second drive motor 58 by the control signal output from the control means 62 described above. To return the fixed plate 56 to its initial position. That is, the fixed plate 56 maintains a right angle with respect to the rising and lowering plate 57.

When the user operates the second button 61b of the switch 61, the first drive motor 53 is driven in the reverse direction by the control signal output from the control means 62. As a result, the driving belt 54 mounted on the driving pulley 77 and the driven pulley 78 is in orbital motion.

Therefore, the lifting and lowering plate 57 fixed integrally to the driving belt 54 is supported by the left and right guides 76 and moved to the lower position. At this time, the door 51 is rotated by the door opening and closing means interlocked with the lowering of the up and down plate 57 to close the opening 50.

That is, when the lifting and lowering plate 57 is lowered, the locking jaw 70 of the lever 71 is urged downward in the drawing by the extension piece 79 which is integrally formed on the lifting and lowering plate 57. (The tensile force of the elastic member 74 is increased). At this time, the locking jaw 70 is moved to the lower end of the slot 72 formed in the bracket (73).

In this way, as the lever 71 is pulled downward, the pivot plate 69 connected to the upper end of the lever 71 is rotated clockwise with its fixing pin as the central axis. Therefore, since the bottom surface of the door 51 is pressed by the pivoting plate 69, the door 51 is rotated about its hinge pin as a center axis and moved to the position which closes the opening part 50. As shown in FIG.

Therefore, the display device 55 fixed to the fixing plate 56 is accommodated in the body 52 due to the lowering of the raising and lowering plate 57. At this time, the door 51 is rotated by the opening / closing means of the door 51 interlocked with the lowering of the up and down plate 57 to close the opening 50 formed in the upper portion of the body 52.

At this time, the opening 75 formed in the upper plate of the table is closed by the door 81 (which can be automatically opened or closed by an elastic force not shown, or manually opened or closed by the user).

As described above, the lifting and lowering device of the display apparatus according to the embodiment of the present invention drives the first driving motor 53 due to the operation of the switch 61 to move up and down to which the display apparatus 55 is mounted. As the display device 55 is easily tilted as the steel plate 57 is raised and lowered and the second and second driving motors 58 are moved to move to the upper position where the rising and lowering plate 57 is set, the display device 55 is tilted. Can be monitored.

As the door 51 is rotated by the door opening / closing means interlocked with the above-mentioned lifting / lowering plate 57, the opening 50 is formed on the upper portion of the body 52. In the case of using the door 51, the door 51 is opened to raise the display device 55 onto the table top, and when the display device 55 is not used, the display device 55 is stored inside the table and the door 51 You can close the table to make good use of the space on the table.
