Description

[Detailed description of the invention] [Industrial application field] The invention can be attached to various display devices.
The present invention relates to a CRT mounting device, and more particularly to a mounting device that has sufficient strength and has a simple structure by mounting the CRT on a flange provided on a cabinet.

[Conventional technology]

Conventionally, CRTs (cathode ray tubes) have been widely used in television receivers and various display devices, and are usually housed in a cabinet. By the way, recent cabinets are often made of plastic, etc. by molding, and in the past, they were made using the following mounting device.
A CRT is installed in the cabinet.

First, FIGS. 1 to 3 show an example of a conventional mounting device.

In this example, the CRT 1 is provided with four mounting pieces 3 for attaching and fixing to the cabinet 2, and these mounting pieces 3 have bolts passing through them for fixing to the cabinet 2, which will be described later. A hole 4 is provided for positioning the CRT 1. On the other hand, the cabinet 2 is formed into a substantially box shape by molding plastic.
An opening 5 is provided through which the screen of the CRT 1 faces the outside. A boss 7 is formed on the inner side of a wall surface 6 located around the opening 5 at a position opposite to the piece 3 provided on the CRT 1. The CRT 1 and the cabinet 2 are arranged by aligning the mounting piece 3 formed in this way with the boss 7, and the bolt 8 is inserted into the boss 7 through the hole 4 provided in the mounting piece 3. is fixed with screws.

As described above, the mounting device for fixing the CRT 1 may not be able to securely hold the CRT 1 as the CRT 1 increases in size.
In other words, the weight of the above CRT1 is equal to the weight of the cabinet 2.
There is a risk that the four bosses 7, which are provided in the center, will be concentrated and damaged. For this reason, it is necessary to make the boss 7 large, but from the viewpoint of molding the cabinet 2, especially if the boss 7 is made large,
A sink mark occurs on the back surface 9 side of the wall surface on which the boss 7 is provided, resulting in a very unsightly appearance. Therefore, the boss 7 cannot be increased in size without limit, and it becomes impossible to hold the CRT 1 due to its strength.

Therefore, in order to solve the above-mentioned problems, a mounting device for holding a relatively heavy CRT via a mounting tool has been proposed.

This mounting device fixes the CRT mounting piece and the cabinet boss via a fixture made of metal, plastic, or the like. And C.R.T.
The mounting pieces are respectively fixed to the above-mentioned fittings with bolts and nuts, and the fittings are respectively fixed to a plurality of bosses provided on the cabinet with bolts. Therefore, for example 1
Each mounting piece can be supported by three to four bosses, making it possible to sufficiently hold a large CRT.

[Problem that the invention attempts to solve]

However, in the above-mentioned mounting device, there are many places where screws are fastened, making the assembly work extremely complicated. In addition, to the cabinet
In order to avoid the concentrated load of the CRT's weight, the positions of the bosses must also be distributed. Therefore, the size of the above-mentioned fixture becomes large, and the number of bosses and bolts also increases, resulting in a significant increase in cost.

Furthermore, in cases where the cabinet is integrally molded as a box body, as in the conventional example mentioned above,
It is necessary to install the CRT only from the rear of the cabinet, resulting in extremely poor work efficiency. Furthermore, as the size of the CRT increases, the size of the cabinet also increases, making it technically difficult to integrally mold the cabinet. In addition, when the cabinet is integrally molded in this way, it is difficult to vary the design, for example, in color, material, surface finish, etc.

For this reason, it is known that the cabinet is divided into a front cabinet and a rear cabinet, and the CRT is first attached to the front cabinet, and then the rear cabinet is attached. By using a cabinet divided into two parts in this way, it is possible to solve problems in assembly work efficiency, manufacturing the cabinet, and design.

However, in the case of using a cabinet divided into two, it is necessary to fix the divided front cabinet and rear cabinet.
Therefore, the assembly work becomes complicated and the cost becomes large. Furthermore, in the above conventional example, regarding the CRT mounting device,
There was no way to overcome these shortcomings.

Therefore, the present invention aims to solve the problems of the conventional devices as described above, and to provide a CRT mounting device that has sufficient strength so that it can sufficiently hold a large CRT. It was proposed for this purpose.

Furthermore, the present invention has been proposed with the aim of providing a CRT mounting device that can improve the workability of CRT mounting work and significantly improve the efficiency of assembly work.

Furthermore, the present invention was proposed for the purpose of providing a CRT mounting device that can simplify the assembly work by reducing the number of screw fixing points, and can significantly reduce costs. .

Furthermore, the present invention has been proposed for the purpose of providing a CRT mounting device that can be easily manufactured by molding.
