Abstract

PROBLEM TO BE SOLVED: To reduce installation space for a thin display. SOLUTION: The upper end parts of a pair of rod members 21a and 21b are coupled turnably with a mounting base 15 where a display body is placed, and the lower end parts are provided on a base 13 slidably in the right-left direction to constitute a 1st elevating mechanism 21. A 2nd elevating mechanism in the upside down structure of the 1st elevating mechanism 21 is provided between the base 13 and mounting base 15 behind the 1st elevating mechanism 21 in parallel. When the display body is lifted by hands together with the mounting base t 15, the lower end parts of the rod members 21a and 21b move to the center to increase the height of the 1st elevating mechanism 21. A rod member restricting means 23 which uses wires 25 and 27 restricts the movement of the lower end parts of the rod members 21a and 21b. Consequently, the display body can be held at a desired height. The installation space is reduced as compared with a system which supports the display body on the backside or both the right and left sides of the display body.

When the display device main body 14 is lifted by hand, the lower end portions of both rod-like members 21a and 21b slide inward, respectively, to allow the mounting table 15 to rise. At this time, the wires 25 and 27 are prevented from sagging due to the elastic rewinding force in the direction b due to a torsion spring or the like built in the pulleys 26 and 28. Further, since the movement of the wires 25 and 27 in the extending direction of the arrow a in FIG. 4 is stopped by the stopper 29, the weight of the display device main body 14 is supported by the wires 25 and 27, and the display device main body 14 is moved to a desired height position. Can be stopped. Operating state B in FIG.
((C)) is a state in which the display device main body 14 is further raised, and finally, as shown in FIGS. 5 (a) and (d), the lower end portions of both rod-shaped members 21a and 21b coincide or substantially coincide with each other. You can move to where you want.

In the above elevating operation, since the display device main body 14 is supported by the front and rear first and second elevating mechanisms 21 and 22, the display device main body 14 is stably supported. The first lifting mechanism 21 and the second lifting mechanism 22
At the highest position, each is individually triangular and has a mode such as point support, but since the first lifting mechanism 21 and the second lifting mechanism 22 are upside down, the display device main body 14 as a whole is Can be stably supported.
Since the elevating mechanism 11 is within the range of the base 13 or the mounting table 15, the elevating mechanism 11 does not increase the installation space. Therefore, unlike the conventional stand type or the double-sided support type, there is no problem that a large installation space is required on the rear side and the left and right side surfaces, and the thin display device 12 can be saved in space. Further, since one end of a pair of bar-shaped members arranged so as to be able to intersect is rotatably connected and only the other end is slidably provided, for example, unlike a case where a mere pantograph mechanism is employed, the lifting and lowering is performed. While the width of the mechanism 11 is kept small, a sufficient amount of rise can be secured.
