Description

[Detailed description of the invention] This invention relates to a device for mounting chassis services and metal fittings to cabinets used to improve serviceability in electronic equipment such as television receivers. This allows the chassis service fittings themselves to be used for fixing without using them.

When servicing a television receiver, the chassis is removed from its fixed position and held at the open end of the cabinet 1 as shown in FIG. can be easily installed and removed.

FIG. 2 shows a conventional example of the mounting means.

In FIG. 2, a chassis service fitting 3 that forms a gap with the surface of the cabinet 1 is fixed to the cabinet 1 with a plurality of screws 4, while a protruding piece 5 is provided on the chassis 2 itself, and the protruding piece 5 is By fitting it into the gap between the cabinet 1 and the chassis service fitting 3, the chassis 2
was held in a removable manner.

However, in this case, as shown in FIG. 3, multiple screws 4 are required to attach the chassis service fitting 3.
This has the disadvantage that the number of parts increases and the number of man-hours increases.

The present invention has been devised in view of the above points, and is characterized in that the chassis service fitting itself is used for fixing.

One embodiment will be described below with reference to FIGS. 4 to 7.

In this embodiment, first, a chassis service fitting 10 is constructed as shown in FIG.

This chassis service fitting 10 includes an engagement piece 13 that passes through a rectangular hole 12 provided in the cabinet 11 and engages with the back surface of the cabinet 11, as shown in FIG. A pair of leg pieces 15, 15 are provided at the end opposite to the end where the raising piece 14 and the engaging piece 13 are provided, and the side edges of each leg piece 15, 15 are processed into a sawtooth shape. are doing.

6 and 7 are diagrams for explaining the installation operation. First, as shown in FIG. 6, insert the retaining piece 13 into the rectangular hole 12, and in this state, attach the leg pieces 15, 15. Rectangular hole 1 at the end
Push it inside 2.

As a result, as shown in FIG.
The serrations 16.16 cut into the side walls of the rectangular hole 12.

As a result, the chassis service fitting 10 is connected to the cabinet 1.
No more than 1 will fall off.

At this time, a gap is created between the cut and raised piece 14 and the surface of the cabinet 11, and a part of the chassis (not shown) is inserted into this gap to hold the chassis.

As described above, according to the present invention, by fixing the chassis service fitting to the cabinet using the fitting itself, the number of parts is reduced, and the number of assembly steps can be reduced, thereby improving work efficiency.
