Description

[Detailed description of the invention] "Field of industrial application" This invention is a light emitting body formed in a plate shape such as a liquid crystal or electroluminescent device used as a display of electronic equipment such as a personal computer or a word processor. When used as an indicator,
The elevation angle of the display can be adjusted freely and smoothly with a single touch.
The present invention relates to an undulation adjustment device for a planar display that can be changed silently.

``Conventional technology'' For example, a liquid crystal display may be fully visible, or may be too bright to be seen, depending on the ambient illuminance in the office where the OA equipment is installed, the angle of incidence of extraneous light on the display, and the angle at which it is viewed. It is known to do. Therefore, proposals have been made to change both the display surface and the display device using driving means so that the elevation angle of such a planar light-emitting display can be changed freely (for example, Japanese Utility Model Application Publication No. 112284/1984). More specifically, a technique is known (Japanese Utility Model Publication No. 59-128684) in which a concave-convex arc-shaped slider is provided on the back surface of a display body to make the display surface variable in the vertical direction.

However, when the above-mentioned planar display body is folded in prone contact with the top surface of the main body case of an electronic device, or when it is used as a lid body, the above-mentioned prior art becomes three-dimensionally bulky, which is extremely inconvenient. be.

``Problems to be solved by the invention'' Therefore, in order to fully demonstrate the display function, the invention makes it possible to smoothly vary the elevation angle of the planar display body at any viewing angle and steplessly. The object of this invention is to provide a means for changing the angle of the display surface that is not bulky and can be installed in a manner that is not visible from the outside.

``Means for Solving the Problems'' Therefore, the present invention includes a pair of brackets that connect the support pair on which the planar display is mounted and the main case in which the planar display is installed, and It is constructed by a fastener that tightens the angles arranged opposite to each other in series.

``Example'' An example of the present invention will be explained in detail with reference to the drawings below. Figure 1 is a perspective view of the main part of the undulation adjustment device of the present invention, and Figure 2 is a view of the support mounting surface of the planar display. A top view, FIG. 3 is a back view of the case top plate of the main body of the electronic device, and FIG. 4 is an exploded view of the fastener.

First, in Fig. 1, reference numeral 1 denotes the top plate of the main body case of an electronic device, and is intended to vary the angle α formed with the back surface of a support 20 for attaching a surface display such as an LCD. When lying down, it comes into contact with the above-mentioned top plate. Reference numeral 31 denotes a base bracket 41 fixed at its base via a boss 10 on the back surface of the top plate, as shown in FIG.
The planar display mounting surface 21 of the support body is protruded through the respective holes. The guide grooves are provided parallel to each other so that the support and the top plate of the case are maintained in corresponding positions with each other, and the upright portions of the base bracket are maintained in a state in which they pass through the respective guide grooves in parallel. On the other hand, on the surface of the support body on which the planar display is mounted, angles 51 are fixed along the opposing parallel guide grooves via bosses 9, as shown in FIG. In order to form a fulcrum of the body, the pair of base brackets and the pair of angles are passed through and tightened in series, as shown in FIG. 3 and is fastened with a nut 7. Here, the tightening bolt is tapered and stepped in the axial direction, is inserted into the cylinder together with the collar, and is tightly fastened, and is properly tightened without loosening even when it is raised and lowered as a surface display. So it can maintain a long service life.

Although FIG. 1 shows only one undulation adjustment section of the present invention, one set is provided at the fulcrum for undulation or opening/closing, that is, in the direction of the support axis.

``Effect of the invention'' Thus, according to the invention, gears or the like are not used as a means for holding the planar display at a desired angle.
It can be made to rise and fall completely continuously, smoothly and quietly,
Moreover, the desired angle can be maintained without generating noise.

The support pair with the planar display attached here is opened and closed at a speed of 8 times per minute, with a pause of 1 minute every 20 times.
As a result of measurement using a tension gauge under the condition of stopping for 15 minutes every 500 times, the operating force in the standing direction and prone direction is expressed in kg, and the initial
1.95Kg becomes 1.45Kg at 6×10 ^3rd time, and in the prone direction, 1.35Kg at the beginning becomes 0.90Kg at 6×10 ^3rd time, and it was demonstrated that the surface display body can still be held at any angle. Of course, no adjustments were made to the fasteners during this testing period.

Therefore, there is the practical benefit of being able to adjust the elevation of the planar display without occupying extra space.
