Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a television receiver that is resistant to drops and vibrations and shocks, and to which electrical components can be attached from the outside.

Traditionally, productivity has been improved by reducing labor and increasing production speed through mechanization. It would be possible to assemble machines using the same structure as current TV receivers, but it would be more like a robot that could perform the same human hands and movements.
It has the disadvantage of being a very expensive investment.

A conventional example will be specifically explained.

As shown in Fig. 1 and Fig. 2, the conventional examples are shown in Figs. The structure is such that a CRT chassis, etc.) is inserted and attached to an escutcheon or cabinet. For this reason, work to install parts, process lead wires, and adjust circuits must be done inside the box-shaped cabinet, which is very inefficient. Furthermore, in the case of compact products with low inches, it is difficult for human hands to reach them, which greatly reduces work efficiency.

The present invention eliminates the drawbacks of the prior art, and has a framework that can hold heavy electrical components and withstand drops, shocks, and vibrations even when no escutcheon or cabinet is attached, and allows electrical components to be attached from the outside. To provide a television receiver in which a rear top plate and side plates can be fitted to an escutcheon and a back plate.

FIG. 3 shows a partially exploded perspective view of the television receiver of the present invention.

In the figure, 1 is a CRT, 2 is a main chassis, 4 is a framed frame, 5 is a bottom plate of the set, and 6-α is a top plate 6-α which is an extruded cabinet.
β, 6-δ are left and right side plates, 7 is an escutcheon, 7-1 is an upper horizontal upper engagement rail,
7-2 is a vertical right engagement rail on the right side; 7-3 is a vertical left engagement rail on the left side (not shown); 1
0 indicates the back plate.

In the frame 4 of the present invention, two vertical angles 4-1, 4-2, 4-3 are made up of horizontal groove-shaped beams and diagonal supports 4-4, 4-5. The frame 4 is fixed to the bottom plate 5 with screws. Beam section 4-3
and angles 4-1 and 4-2 with screws. A frame body X is composed of a frame 4 and a bottom plate 5. A forehead-shaped frame X is shown in FIG. 4A, and a frame Y having a box-shaped frame is shown in FIG. 4B. In order to create a structure that can withstand drops and vibration shocks, it is important to select the structure of the frame body by inch as shown in FIG. 4A or B.

Since all electrical performance parts can be installed in the state shown in Figure A or Figure B, human hands and machines can work freely from the top, left, right, and rear of the set. This significantly improves line processing, adjustment work, and installation workability. In addition, the present structure makes it possible to carry out mechanical work, which was conventionally not possible due to screwing in a space narrower than the rear of the set.

The mounting structure of the exterior parts of the present invention will be explained.

FIG. 5 shows a sectional view of a structure in which the top plate, side plate, bottom plate, escutcheon, and back plate of the present invention are fitted together. The lower part of one end of the bottom plate 5 is removed to form a protrusion 5-1.
Configure. A groove-shaped locking tool 5-2 that opens upward is fixed to the other end with a screw 5b. The escutcheon 7 is provided with a protruding piece 7-5 at the lower part thereof, slightly above the lower protruding part 7-4 and parallel to the protruding part 7-4.
A C-shaped fitting part 6-1 that opens outward is provided at the lower end of the top plate 6-α, and a groove with a width that allows the groove-shaped beam part 4-3 to fit together with one side of the fitting part 6-1. 6-2
A fitting groove 6-3 having a width into which the back plate 10 is inserted is formed on the lower surface of the rear end. side plate 6-β,
Similar to the top plate 6-α, 6-δ has a fitting part 6-1, a fitting groove 6-3, fitting parts 6-1β, 6-1δ, and a fitting groove 6 having the same structure at the left and right ends of the inside. -3β,6-3
Angle 4-1, 4-
Fit 2. Grooves 6-2β and 6-2δ are provided.

Figure 6 shows a perspective view just before completion. FIG. 7 shows a rear view of the television receiver of the present invention before inserting the decorative beam into the corner and fixing the corner reinforcing metal fittings with screws. Although not shown in FIG. 3, stepped portions P ₁ and P ₂ are provided on both edges of the upper surface of the top plate 6-α, and stepped portions Q and R are provided on the outside of the upper portions of the side plates 6-β and 6-δ, respectively. Furthermore, protrusions T are provided on both sides of the corners of the upper back surface of the escutcheon 7.

On the other hand, a square cylindrical decorative arm K is provided, a pair of right-angled sides are extended, and projecting edges 8-1, 8-1 are provided.

Next, the procedure for attaching the exterior parts of the television receiver of the present invention will be explained.

1 Projection part 7-4 of escutcheon 7 and projection piece 7
-5, the protruding portion 5-1 of the bottom plate 5 is inserted between the bottom plate 5, the lower part of the back plate 10 is inserted into the locking tool 5-2 fixed to the bottom plate 5, and the back plate 10 is made to stand upright at a certain position using a jig.

2. Insert the side plates 6-β and 6-δ from above. The side plates 6-β have fitting portions 6-β on the left engagement rail 7-3 of the escutcheon 7, the angle 4-2, and the side of the back plate 10. , groove 6-2β and fitting groove 6
-3β is fitted. The side plate 6-δ also fits in the same way as the side plate 6-β.

3 From the side of the top plate 6-α, insert the fitting part 6 of the top plate 6-α
-1, the groove part 6-2 and the fitting groove part 6-3 are connected to the upper engagement rail 7-1, the beam part 4-3 and the back plate 10.
Attach it by fitting it onto the upper edge of the holder as shown in Figure 5.

4 As shown in FIGS. 5 and 6, the protruding edges 8-1, 8- of the decorative ledge 8 are attached to the corners formed by the edges of the top plate 6-α and the side plates 6-β, or the side plates 6-δ. 1
The steps P ₁ , P ₂ of the top plate 6-α and the side plates 6-β, 6-
Slide it along the stepped portions Q and R of δ and insert it from the rear surface, and fit the decorative lug K into the protrusion T.

5. Fix the corner reinforcing metal fittings 9 with screws as shown in Fig. 6 to prevent the decorative trusses K from coming off.

The structure shown in FIG. 5 when the cabinet is made of wood is basically the same in terms of the fitting structure and can be expanded.

Since the present invention has the above configuration, it produces the following effects.

(1) Cabinets can be manufactured in-house.

(2) Machine introduction is easy and leads to labor savings.

(3) Improving factory assembly operations.

(4) Compact products become possible.
