Description

[Detailed description of the invention] [Summary] A rotary table for a display device, which includes a mounting plate member having an engagement protrusion inside a ring-shaped protrusion on the lower surface, and the protrusion fitted into the upper surface. The rotation angle of the display device can be adjusted by providing a base plate member having a concave portion with a diameter of about 100 mm and a plurality of mounting holes through which stop members can be detachably attached at a plurality of predetermined angular positions inside the concave portion with respect to the front direction. It can be used by setting within the desired angle.

[Industrial application field]

The present invention relates to a rotary table for a cathode ray tube (hereinafter referred to as CRT) display device, and particularly to a rotary table whose rotation angle can be set to a predetermined angle or less.

[Conventional technology]

In recent years, CRT display devices have been widely used as accessory devices for computer terminals and word processors. In particular, its use is expanding with the advancement of office automation, and it is also used for transactional dialogue between customers and clerks at financial institutions' consultation corners.

As shown in FIG. 4, the display device 1 is usually installed on a table, and the rotating table 2 on which the display device 1 is mounted is composed of a rotating mounting plate 3a and a base plate 4a. circular convex part 3
0a is rotatably fitted into the circular recess 40a of the base plate 4a. Further, a mounting section 20 is provided on the upper surface of the mounting rotary plate 3a, and the display device 1 is mounted thereon.

Therefore, by pushing the display device 1 mounted on the rotary table 2 in either the left or right direction of rotation,
The mounting rotary plate 3a rotates on the base plate portion 4a, and the orientation of the screen can be changed to any angle.

The orientation of the screen can be freely changed depending on the purpose of use, that is, there are those that can be rotated 180 degrees or more left and right, and there are those that can be rotated up to a specific angle, for example, only 45 degrees left and right.

[Problem that the invention attempts to solve]

According to the above conventional methods, some can be rotated left and right by more than 180 degrees, while others can only be rotated up to a specific angle. This is convenient when you need to view the screen in the opposite direction, but when you do not need to show the screen in the opposite direction and would rather limit the rotation angle, or due to the layout of the device, you may want to avoid damaging other items when changing the angle. If there is a possibility that
This cannot meet the demand for rotation within a predetermined angle, such as when it is desired to prevent damage to the device cable due to repeated movement.

In the case of , it may be possible to meet the request of , but since the rotation is set to a specific angle, the angle cannot be changed further depending on the purpose of use.

Therefore, there is a problem in that when a desired rotation angle is required, it must be specially manufactured.

Therefore, a mechanism is desired that allows selection of the rotation angle according to the purpose of use.

[Means for solving problems]

FIG. 1 is a diagram showing the principle of the present invention. In the figure, 3 is a mounting plate member in which an engagement protrusion 31 is provided inside a ring-shaped protrusion 30 formed on the lower surface, and 4 is a mounting plate member that has a protrusion 30 and an engagement protrusion on the upper surface at all rotational positions. 31 is fitted into the recess 40, and is located inside the outer periphery of the recess 40 at a plurality of predetermined angles with respect to the center line in the front direction from the center and at positions whose distances from the center correspond to the engagement protrusions 31. This is a base plate member provided with a plurality of mounting holes 41 in which the stop member 5 is detachably mounted.

Therefore, at least one stop member 5 is attached to the attachment hole 41 at a predetermined angle position, the engagement protrusion 31 is positioned on the front center line side of the stop member 5, and the protrusion 30 is fitted into the recess 40. It is configured as follows.

[Function] At least one stop member 5 is attached to the attachment hole 41 at a desired angular position of the base plate member 4, and the recess 4
0 to the convex portion 30 and engagement protrusion 31 of the mounting plate member 3
When the mounting plate member 3 is rotated in either the left or right direction, the engagement protrusion 31 moves along the inside of the outer periphery of the recess 40, engages with the stop member 5, and is no longer rotated. is prevented.

Therefore, by changing the stop member 5 to a different position in the mounting hole 41, the rotation angle can be freely changed depending on the purpose of use, and the rotation angle can be increased or limited.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 2 and 3. The same reference numerals indicate the same objects throughout the figures.

As shown in FIGS. 2a and 3, the rotating table 2a
is composed of a mounting rotary plate 3b and a base plate 4b.

As shown in FIG. 2b, the mounting rotary plate 3b has a ring-shaped protrusion 30a formed on its lower surface, and an engagement protrusion 31a provided inside the ring-shaped protrusion 30a. The mounting rotary plate 3b, the convex portion 30a, and the engaging protrusion 31a are the first
The mounting plate member 3, the protrusion 30, and the engagement protrusion 3 shown in the figure
1 respectively.

As shown in FIG. 2c, the base plate 4b has a circular recess 40a formed on its upper surface, passing through the center of the recess 40a, and forming the recess at a predetermined angle from the front surface with respect to the longitudinal center line of the base plate 4b. Attachment holes 41a to 41g are provided inside 40a. The base plate 4b, the recess 40a, and the attachment holes 41a to 41g correspond to the base plate member 4, the recess 40, and the attachment hole 41 in FIG. 1, respectively.

As shown in FIGS. 2a and 2d, stop pins 5a and 5b are detachably attached to any of the attachment holes 41a to 41g (attachment holes 41b and 41f in the figure) at desired angular positions. The mounting angular positions of the stop pins 5a and 5b are precision positions that regulate the rotation angle of the screen of the display device. The stop pins 5a and 5b are the stop member 5 of FIG.
It corresponds to

The engagement protrusion 31 engages the protrusion 30a of the mounting rotary plate 3b.
Recessed part 40a of base plate 4b so that a is located in front
The insertion part 32, which is rotatably fitted into the rotary mounting plate 3b and has a slit around the center of the mounting rotary plate 3b to provide elasticity, is inserted into the center hole 42 of the base plate 4b, and the claw at the lower end of the insertion part 32 is inserted into the center hole 42 of the base plate 4b. 33 is assembled by engaging with the lower end of the center hole 42.

With such a configuration, the mounting hole 41
Since the stop pins 5a and 5b are attached to the stop pins 5a and 5b, when the screen of the display device 1 is rotated to the left or right, the mounting rotary plate 3b rotates and the engagement protrusion 31a is attached to the stop pins 5a and 5b.
It can be rotated until it engages, and cannot be rotated beyond that point.

Here, only the stop pin 5a is attached to the mounting hole 41b.
When attached to the screen, it can be rotated approximately 180 degrees from side to side, making it possible to freely change the direction of the screen without limiting the angle.

In addition, the stop pins 5a and 5b are attached to the mounting holes 41.
When attached to the screen 41g, the screen can only be rotated to the left and right within a narrow range of angles, making it possible to further limit the rotation angle of the screen.

In this way, the rotation angle can be changed by changing the mounting position of the stop pins 5a and 5b, so it is possible to limit the screen rotation to within a predetermined angle depending on the purpose of use, and create a rotating table for a specific angle. It is economical as there is no need to do so.

[Effect of idea]

As explained above, according to the present invention, rotation can be easily limited to within a desired rotation angle.

This is extremely economical compared to manufacturing a rotary table with a specific rotation angle.

There is an effect.
