Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a CRT display device supported by a chilled stand.

[Problems that conventional technology and ideas try to solve]

FIG. 4 shows a conventional CRT display device, in which a chilled stand 2 is mounted on a stand 1 so that its angle can be adjusted freely, and a bezel 3 that forms the front frame of the device is mounted on the chilled stand 2. A CRT display tube 4 is attached to the back side of the device, and the CRT display tube 4 is covered with a box-shaped back cover 5. In addition, 6 in the figure is a mounting plate (PC
board). Further, a flat flange plate 7 is provided on the top surface of the chill table 2, and the bezel 3 is attached to the front part of the flange plate 7, and the back cover 5 is attached to the rear part of the flange plate 7.
They are each fixed with screws 8.

Further, FIG. 5 shows another conventional device. This has been improved to reduce the height of the bezel 3, and a flange plate 9 with a bent front part is attached to the top surface of the chilled table 2, and the bottom plate of the back cover 5 is tilted forward.

These conventional devices had the following problems.

In order to stably attach the bezel 3 and back cover 5 to the chilled stand 2, a wide flange plate 7 or 9 is provided.
Requires.

When performing maintenance/inspection of the CRT display tube 4 and other housed parts, if the back cover 5 is removed from the flange plate 8, the center of gravity will move forward and the stand 1 will fall forward. 4 and various electrical parts must be removed from the chiller stand 2. However, since the CRT display tube 4 is heavy, it is difficult to remove it.

Therefore, the purpose of the present invention is to eliminate the need for a wide flange plate like the conventional device shown in FIGS.
Another object of the present invention is to provide a CRT display device in which the back cover can be removed from the chiller stand without overturning the stand, and maintenance and inspection of the CRT display tube and other housing parts can be easily performed by simply removing the back cover from the chiller stand.

[Means for solving problems]

In this invention, a bezel that forms a frame is attached to the front of the device on a chilled stand that is attached to the stand so that the angle can be adjusted freely, and a bezel that forms a frame is attached to the back side of the bezel.
Install the CRT display tube and various electrical parts to operate this tube, and
In a CRT display device in which a CRT display tube and various electrical components are covered with a box-shaped back cover, a connecting mechanism is provided on the back side of the bezel to connect the bezel and the chill stand to form an integrated structure, and the back cover An opening for insertion of the coupling mechanism is provided in the bottom plate part, so that the back cover can be attached to and removed from the integral structure of the bezel and the chiller base, and the edge of the opening is joined to the edge of the chiller base. It is characterized by the following.

[Effect]

When performing maintenance or inspection of the CRT display tube or other housed parts, simply remove the back cover from the chiller base. In this case, since the bezel is connected to the chill stand by a connecting mechanism and is an integral structure, there is no risk of the stand tipping forward.

〔Example〕

An embodiment of the present invention will be shown below.

Fig. 1 shows an exploded view of a CRT display, in which reference numeral 11 is a stand, 12 is a chill stand that can be mounted on the stand so that the angle can be adjusted freely, and 13 is a stand.
14 is a CRT display tube attached to the back side of the bezel 13, and 15 is a box-shaped back cover that covers the CRT display tube 14. Also accommodated within the back cover 15 is a mounting plate (PC board) 16 on which various electrical components for operating the CRT display tube 14 are mounted.

At each of the four corners of the bezel 13 and the back cover 12, screw mounting bosses 17 and 18 are provided that abut each other as shown in FIG. Insert the screws and attach both mounting bosses 17, 1.
8 are screwed together. Furthermore, the bezel 13 is also provided with a tube attachment boss 19, to which the front edge of the CRT display tube 14 is screwed.

Further, as shown in FIG. 1, a horizontally long slit 20 is provided at the lower front of the bezel 13, and a sliding volume 21 is inserted into this slit 20. Note that 22 in the figure is a volume knob.

In the figure, reference numeral 23 denotes a connecting metal fitting that constitutes the connecting mechanism. This metal fitting 23 includes the bezel 13 and the chilled stand 12.
The bezel 13 and the chilled stand 12 are screwed to bosses 24 and 25 provided respectively, thereby forming an integral structure. Furthermore, a pair of left and right rail-shaped fittings 26 are screwed to the connecting fittings 23,
Both rail-shaped fittings 26 fit and hold both edges of the mounting plate 16.

An insertion recess 28 that opens toward the rear is formed on the lower surface of the bezel 13, and the front end edge of a flange plate 29 provided on the upper surface of the chilled base 12 is fitted into this recess 28 from the rear. .

The lower surface of the chilled table 12 has a convex curved surface, and the upper surface of the stand 11 that supports the chilled table 12 has a concave curved surface. As shown in FIG. 1, a pair of left and right elongated holes 30 are provided in the concave curved surface.
It is held by a screw 31 screwed into the chill stand 12 through it, so that the angle of the chill stand 12 with respect to the stand 11 can be freely adjusted.

The bottom plate 32 of the back cover 15 is provided with an opening 33 that opens toward the front, allowing the back cover 15 to be attached to and removed from the integral structure of the bezel 13 and the back cover 15. Further, a fitting recess 34 is formed at the rear end edge of the opening 33, and when the back cover 15 is attached to the integral structure of the bezel 13 and the back cover 15, the edge of the opening 33 and the flange plate 19 are connected to each other. The fitting recess 34 is adapted to fit with the rear end edge of the flange plate 29 on the top surface of the chilled stand 12.

In the above configuration, when performing maintenance and inspection of the CRT display tube 14 and other housed parts, remove the screws fixing the bezel 13 and the back cover 15 at the four corners, and pull the back cover 15 backwards. Bezel 13 and chilled stand 12
The back cover 15 can be removed from the integrated structure. At this time, bezel 13 and chilled stand 1
2 remains connected with the connecting fitting 23, and the center of gravity position hardly moves, so
There is no risk that the stand 11 will fall forward. Therefore, just by removing the back cover 15, the CRT
The display tube 14 and other housed parts can be maintained and inspected, and assembly after maintenance and inspection can be easily carried out by simply attaching the back cover 15 to the integral structure.

[Effect of idea]

As described in detail above, the present invention is to attach a bezel that forms the front frame of the device to a chiller base that is attached to a stand so that its angle can be adjusted freely, and to operate a CRT display tube and this tube on the back side of this bezel. The CRT display tube and various electrical parts were covered with a box-shaped back cover.
In the CRT display device, a connecting mechanism is provided on the back side of the bezel to connect the bezel and the chiller base to form an integral structure, and an opening for inserting the connecting mechanism is provided in the bottom plate of the back cover. Since the back cover is detachable from the integrated structure of the CRT display tube and the chiller base, and the edge of the opening is joined to the edge of the chiller base, the CRT display tube and other housing parts can be When performing maintenance or inspection, simply remove the back cover from the chiller base. In this case, since the bezel is connected to the chill stand by a connecting mechanism and is an integral structure, there is no risk of the stand tipping forward. Therefore, according to the present invention, there is no need for a wide flange plate like the conventional device shown in FIGS. 4 and 5, and only the back cover can be removed from the chilled stand without overturning the stand. Maintenance and inspection of the display tube and other related parts can be easily performed by simply removing the back cover.
