It is fixed at b. Note that the regulating member can be attached to two locations, and in this case, the aperture angle can be set to β, and when it is attached only to one location, the aperture angle can be set to α. Furthermore, it goes without saying that if regulating members with different lengths are prepared, these opening angles can be further set in various ways.

The operation of the rotary table device of this embodiment configured as described above will be described below.

First, the pedestal 1 is placed stably in contact with the floor surface,
A rotating table 4 is mounted on the top thereof and rotates in the horizontal direction using the center of the pedestal 1 as a fulcrum. At this time, the monitor stand 8 rotates in the horizontal direction at the same time as the rotating stand 4. The display monitor can therefore be rotated freely in the horizontal direction.

Next, the monitor stand 8 moves in a curved line along the curved surfaces of the sliding surfaces 9a and 9b provided on the left and right sides of the lower surface in the direction of arrow A, that is, in the front and back direction when viewed from the screen of the display monitor, and moves in a curved line along the chain double-dashed line in FIG. Although the monitor stands 8F, 8B can be moved to the maximum position shown by , the aperture angle can be set to an angle β smaller than the maximum aperture angle by the regulating members 19a, 19b. Note that the display monitor can also be rotated in the vertical direction in accordance with this aperture angle β. Furthermore, since the sliding pieces 5a to 5d of the sliding table 5 are made of ultra-high molecular weight polyethylene, the sliding surface 9
a, 9b are sliding pieces 5a, 5b and sliding pieces 5c, 5
d can be slid closely and smoothly on the surface.

The post 14 is located in the center of the rotary table device, and the screw 15 is used to connect the rotary table 4 and the monitor table 8 using the upper sliding surface 10 and a washer 17 attached via a compression coil spring 16. It is tightened with. Therefore, the sliding surfaces 9a, 9 of the monitor stand 8
b, the upper surface of the sliding pieces 5a to 5d, the lower sliding surface 14a of the post 14, and the upper sliding surface 20 of the monitor stand 8.
and are sliding while being in pressure contact with each other. Also,
The left and right sides of the tip of the post 14 and the regulating walls 10a, 1
0b regulates the moving direction of the monitor stand 8.
Additionally, the movement direction of the monitor stand 8 is temporarily restricted by the side ends of the sliding surfaces 9a, 9b and the restriction walls 5e, 5f.

As described above, according to this embodiment, the monitor stand 8
It has a rotating stand that is slidably held so that it can be rotated at a predetermined angle (preferably large in advance) in the vertical direction, and regulations that arbitrarily set the range in which the monitor stand 8 can be rotated. Part 19
a, 19b are attached to the mounting bosses 18a, 18b via screws 20a, 20b near the front and rear ends of the elongated hole 11, so that the protrusion 6 at the center of the rotary table 4 penetrates the elongated hole 11, and the elongated When moving the hole 11 in the longitudinal direction, the range of movement becomes narrow as it comes into contact with the regulating members 19a and 19b. Therefore,
The monitor stand 8 has a long hole 11 and regulating members 19a, 19.
Since it rotates according to the aperture angle determined by b, by selecting the length of this regulating member itself and the mounting location, the range of rotation of the monitor stand 8 in the front and rear direction can be adjusted arbitrarily. can be adjusted.

In addition, in this embodiment, sliding plates 5a to 5d made of ultra-high molecular weight polyethylene are fixed to the four corners of the front, rear, left, and right of the sliding table 5 of the rotating table 4, and the sliding plates 5a to 5d are mounted on a monitor stand. Since it slides on the sliding surfaces 9a and 9b provided at the left and right ends of the monitor stand 8, the monitor stand 8 can be moved vertically smoothly with a very simple configuration.
Moreover, the rotary motion can be performed stably.
Furthermore, by using this sliding plate, the impact resistance is extremely high, and it also has a noise-muffling effect, and this property does not deteriorate even at low temperatures. Also,
These sliding plates 5a to 5d have particularly excellent wear resistance and are highly self-lubricating, so there is no need to perform any maintenance work to maintain performance, and the reliability of the equipment can be increased. .

Effects of the Invention As described above, according to the present invention, there is provided a rotating stand which is slidably held so as to be able to vertically rotate a monitor stand by a predetermined angle, and the monitor stand is attached to the monitor stand. By providing a restriction member that arbitrarily sets the range of rotational movement, it is possible to easily change the rotation angle by preparing multiple types of restriction members with different lengths, instead of using a rotation table with multiple rotation angles. A variety of different turntable devices can be provided.

In addition, a sliding table having a rectangular planar shape is provided on the top surface of the rotating table, and the four corners of the sliding table are made of ultra-high molecular weight polyethylene, and the sliding surfaces provided at the left and right ends of the bottom surface of the monitor table and sliding surfaces are provided at the four corners of the sliding table. To provide a rotary table device that allows a monitor stand to slide smoothly and stably in the vertical direction with a very simple configuration by fixing a sliding plate for holding the monitor stand, and has an appropriate angle holding force when stationary. be able to.
