Description

[Detailed Description of the Invention] (a) Technical Field of the Invention The present invention relates to a display device, and in particular, to an angle adjustment device that allows the display unit to be oriented at any angle depending on the posture of the operator and the position facing the device. Regarding structure.

(b) Prior art and problems Conventionally, display devices such as display devices usually
The CRT is housed in a cabinet resembling a rectangular parallelepiped,
It has rubber feet etc. on its underside and is used by installing it on the floor or on a table, but since the display screen is fixed to the front of the cabinet, conventionally the display screen can be moved by changing the attitude of the device. Various devices have been proposed for obtaining a convenient screen position according to the physique and preference of the operator.

For example, one of them is shown in FIG. A spherical part 2 is attached to the lower part of the display part 11, and a guide boss 9 projects from the lower part. A rotary cylinder 3 with a concave spherical surface is provided so that the display part 1 rotates in the vertical direction of the arrow by frictional contact with the spherical part 2, and a guide hole 4 is provided in the rotary cylinder 3 to regulate the rotation angle in the vertical direction. has been established. In order to prevent the display section 1 from moving, there are a stopper 5 and a screw 6 as an adjustment mechanism for making frictional contact with the spherical section 2. Also, display section 1
In order to horizontally rotate, the rotary cylinder 3 is engaged with the stand 7, and there is an elastic stopper 8 for fixing the movement at that time.

In order to obtain an arbitrary screen position angle by horizontally rotating the display unit or rotating it upwardly or downwardly, the above-mentioned complicated structure is required and there is a problem in that it requires a large cost.

(c) Purpose of the invention The purpose of the invention is to provide a display section with a simple structure.
The purpose is to have a structure that allows the angle to be varied and to obtain the required performance at a low cost.

(d) Structure of the invention And this purpose is to provide a convex spherical surface 11 having an elongated hole 12 in the front and back direction provided at the bottom of the display section 10,
a support portion 13 having a concave surface that engages with the convex spherical surface 11;
An angle adjustment structure for a display device comprising a support post 15 provided at the center of the concave surface and having an angle 14 that engages with the oblong hole 12 and supports the display section 10, the support post 15 having a lower portion front and back. A boss 16 that engages with the oval hole is provided, and the width a of the boss 16 restricts the angle at which the display unit 10 is rotated from side to side, and furthermore, the width b between the upper surface of the boss 16 and the lower surface of the angle is regulated.
is larger than the thickness of the convex spherical surface 11 at the bottom of the display section, lift and rotate the display section 10 until it hits the lower corner of the angle, align the direction of the angle 14 with the oval hole 12, and then remove the display section 10. This problem is solved by the angle adjustment structure of the display device of the present invention, which further includes a hollow structure for passing the wiring through the support.

(e) Example of implementation of the idea The present invention will be explained in detail below with reference to the drawings.

FIG. 2 is a diagram showing one embodiment of the angle adjustment structure for a display device according to the present invention, in which A is a plan view, B is a front view, and C is a side view.

In the figure, the display section 10 has a convex spherical surface 11 centered at the center of gravity G on the bottom, and an oblong hole 12 that is long in the front-rear direction is provided at the center of the convex spherical surface.

The support part 13 has a concave upper surface and a spherical surface 11 on the bottom surface of the display part.
At the center of the support section 13, there is a support 15 having an angle 14 at the top to prevent the display 10 from falling. It is a clearance fit with the circular hole 12.

The vertical adjustment of the angle of the display section 10 is made possible by using the support 15 as a guide and by aligning it with the oblong hole 12, and by rotating it around the support at an arbitrary position.
It is also possible to adjust the display unit 10 by rotating it left and right. Since the bottom surface of the display section 10 is an oblong hole that prevents horizontal vibration, the display section 10 remains horizontal no matter what angle it is set to and will not tilt left or right.

A boss 16 is provided at the front and rear of the lower part of the column 15, as shown in FIG. 3A, to prevent the column from being rotated beyond a set swing angle (the angle at which it is rotated from side to side). Incidentally, by changing the width a of the boss 16, the setting of the swing angle can be changed. Also, due to the angle 14 on the top of the support column 15, the display part 1 may be damaged due to vibration etc.
0 will not come off the support part 13 and fall.

The distance b between the top surface of the boss 16 and the bottom surface of the angle 14 is made larger than the thickness of the spherical surface 1 on the bottom surface of the display section.
When it is necessary to remove the display part 10 from the support part 13, lift the display part 10 until it touches the lower corner of the angle 14 and rotate it 90 degrees to remove the ellipse of the spherical surface 11 on the bottom of the display part as shown in FIG. Since the directions of the hole 12 and the angle 14 match, the display section 10 can be easily removed without the use of tools. Conventionally, in the case of the type shown in FIG. 1, it was necessary to remove the elastic stopper 8 or remove a screw or the like.

In addition, since the center of the spherical surface 11 at the bottom of the display unit coincides with the center of gravity G of the display unit 10, the display unit 10 will not receive any rotational moment unless human action is applied. 10 remains fixed.

In addition, the pillar 15 has a hollow 17 in the center,
It becomes possible to pass the electrical wiring of the display section 10 through the hollow interior, preventing the external wiring from sagging and maintaining the aesthetic appearance. Furthermore, damage to the wiring due to vertical and horizontal rotation of the display unit 10 can be prevented.

As described above, the present invention has the convex spherical surface 11 at the bottom of the display section.
A simple configuration of the concave support part 13 that supports this is sufficient, instead of the complicated configuration of the convex spherical surface 2 at the bottom of the display, the rotary cylinder 3, and the stand 7 as in the conventional case, and the spherical surface 11 at the bottom of the display. Since the display unit 10 is formed so that its center coincides with the center of gravity G of the display unit 10, the display unit 10 is kept in a fixed state. ) becomes unnecessary.

(f) Effects of the invention As explained in detail above, the angle adjustment structure of the display device of the invention has a simple structure that allows the angle of the display section to be varied, and it is possible to obtain the required performance at a low cost. The effect it can have is great.
