Abstract

PURPOSE:To realize a compact escutcheon and to improve the workability, by unifying the hook part of an fitting to each corner of the escutcheon and holding an end of the fitting to a holding part as well as hooking a fixing band to the other end of the fitting. CONSTITUTION:First a front panel 19 is set into an escutcheon 11. Then four fitting 15 are put into the escutcheon 11 with a holding piece 15a set first and set at each corner part of the escutcheon 11. Then a CRT12 is loaded to the escutcheon 11, and a wire band 16 is hooked to hooking piece 15b at the other end of the fitting 15 respectively. The both ends of the band 16 are tied together with a bolt and nut to further tighten the band 16. Thus the CRT12 and the panel 19 are fixed to the escutcheon 11. In such way, a projection 14 is unified to each corner part of the escutcheon 11. Furthermore it is enough just to hold an end of the fitting 15 to the projection 14. This can realize a compact size of the escutcheon 11 and at the same time improve the workability.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cathode ray tube mounting device, and an object of the present invention is to make a casing for fixing a cathode ray tube more compact and to improve mounting workability.

Current wide-inch cathode ray tubes are panned cathode ray tubes, and the cathode ray tube itself has mounting tabs at its four corners, which limits the ability to design a compact set. Therefore, the mounting ears are provided separately.1. There is a method of fixing a cathode ray tube using a wire band. Figure 1 shows a conventional example of this. Bosses 2' are integrally installed at the four corners of an escutcheon 1 made of a resin molded product (only one location is shown in the figure). While fixing one end of the mounting bracket 3, which will become the ear piece, to the boss 2 with the screw 4, hook and turn the other end 5 of the mounting bracket 3, and tighten both ends with bolts and nuts (not shown) e.
The cathode ray tube 6 was fixed to the escutcheon 1 by using and tightening the connector. Here, 7 is a front plate made of a transparent body.
Since the escutcheon is integrally provided, there is a limit to compactness, and since the installation is done using screws 4, the workability is also poor.The present invention eliminates the above-mentioned conventional drawbacks, and the escutcheon A locking part that can lock one end of the mounting bracket is integrally provided on a part of the side wall of each of the four corners, and while one end of the mounting bracket is locked to this locking part, a wire is attached to the other end of the mounting bracket. The cathode ray tube is fixed by hooking a fixed band on it.

An embodiment of the bower will be described below with reference to FIGS. 2 and 3.

In the figure, reference numeral 11 denotes an escutcheon made of a resin molded product, which has an opening 1 on the front facing the image projection surface of the cathode ray tube 120.
There are 3. Reference numeral 14 denotes a protrusion that is integrally provided on the side wall of each corner of the escutcheon 11, and the surface on which one end of the mounting bracket 15 is engaged is such that the angle between it and the main body of the escutcheon 11 is a right angle or an acute angle. Processed.

The mounting fitting 16 has one end of a rectangular sheet metal bent at a right angle or an acute angle to form a locking piece 15a, and the other end bent into a substantially U-shape to form a wire band locking piece 16b. 16 is a wire band, 17 is a bolt, 18
is the number five. L-shaped joints bent at right angles are fixed to both ends of the wire band 16, respectively, and holes are provided in these joints for the bolts 17 to pass through. The wire band 16 is tightened using a matching nut 18. Further, 19 is a front plate that protects the image projection surface of the cathode ray tube 12.

Next, the assembly will be explained. First, the front plate 19 is placed inside the escutcheon 11.

Next, the four mounting brackets are placed in the escutcheon 11 with the locking pieces 15a at the top, and placed at a portion of each corner of the escutcheon 11. The mounting bracket 16 is flexible, and in this state, it is not bent but is straight and is placed against the side wall of a part of the corner of the escutcheon 11, so that it can be used to attach the cathode ray tube 12 to the escutcheon 11 later. If it becomes a hindrance, try to avoid it. After installing the cathode ray tube 12, each mounting bracket 1
5, connect the wire band 16 and the hook to the hook 16b at the other end of the 5, connect both ends using the bolt 17 and nut 18, and further tighten to attach the cathode ray tube 12 and front plate 19 to the escutcheon 11. Fix it. At this time, the mounting bracket 16 is bent along the seven-channel surface of the cathode ray tube 12 and is brought into close contact with the funnel surface. In this way, according to the present configuration, a protrusion 1 is provided at each corner of the escutcheon 11.
4 is integrally provided, and it is only necessary to lock one end of the mounting bracket 16 to this protrusion 14, the escutcheon 11 can be made more compact compared to the conventional screw fastening method using a boss, and it also requires less work. It is also something that can be improved. As mentioned above, it is preferable that the surface of the protrusion 14 on which one end of the mounting bracket 16 locks is at an acute angle, and that the bending angle of the locking piece 15a at one end of the mounting bracket 16 is also an acute angle.

As explained above, according to the present invention, mounting bracket locking portions are provided at all four corners of the escutcheon, and one end of the mounting bracket is locked to this locking portion, while a fixing band is attached to the other end. The escutcheon is connected to both ends of the fixing pan by turning it, and the cathode tube is tightened to the escutcheon by further tightening.The escutcheon only needs to have a locking part at a part of the corner, so the escutcheon, and even the set. can be made compact, and since it is only necessary to lock one end of the mounting bracket to the locking part, work efficiency is improved. In addition, by providing a part of the corner integrally with the main part, external forces can be applied most easily and the part of the corner can be reinforced, which has an extremely large practical effect.
