Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a mask mounting device for a television receiver, in which a plurality of hooks are formed on a mask, and the hooks are held between a holding frame and a cathode ray tube.

Conventionally, the mask of a television receiver has been attached to a holding frame of a cathode ray tube using screws or the like.

Incidentally, the number of countries to which television receivers are exported has recently increased, and the shape of the mask differs depending on the destination country.

Therefore, when mounting the mask using screws as described above, it is necessary to change the shape of the holding frame depending on the shape of the mask, which has many disadvantages such as decreased productivity and increased costs due to increased mold costs. .

Taking these problems into consideration, this invention was designed to allow masks of different shapes to be attached to the holding frame with a simple configuration. This will be explained in detail with reference to the drawings.

First, in FIGS. 1 to 4 showing one embodiment,
1 is a mask of a television receiver formed into a frame shape from resin or the like; 2 is a mask 1 in a direction perpendicular to the surface of the mask 1;
3 is a protrusion provided at the tip of the outer surface of each hook 2, and 4 is a protrusion extending from the tip of each hook 2 toward the inner surface of the hook 2. 5 is a cathode ray tube; 6 is a claw portion having elasticity formed by bending;
are mounting pieces formed at the four corners of the cathode ray tube 5 and have a screw hole in the center, 7 is a holding frame for the cathode ray tube 5, and 8 is a holding frame 7.
The internal frame 9 is a support against which the mounting piece 6 comes into contact when it is mounted on the holding frame 7 of the cathode ray tube 5. Next, the order in which the mask of the above embodiment is mounted will be explained.

First, as shown in FIG. 3a, the mask 1 is inserted into the holding frame 7 from the front, and the protrusions 3 of each of the seven hooks 2 and the frame-shaped portion of each mask 1 are inserted into the internal frame 8 of the holding frame 7. Attach the mask 1 to the holding frame 7 in a sandwiching manner.

Next, as shown in FIG. 3, the cathode ray tube 5 is placed on the holding frame 7 from behind, and the screws 10 are screwed into the screw holes of each mounting piece 6 of the cathode ray tube 5 and each screw receiver 9 of the holding frame 7. Then, the cathode ray tube 5 is fixed to the holding frame 7.

At this time, as shown in FIGS. 2 and 3, each hook 2 is held between the cathode ray tube 5 and the holding frame I, the mask 1 is fixed, and the protrusion 3 of each hook 2 Since it is locked to the internal frame 8 of 7, the mask 1 will not come off.

In other words, the mask 1 can be held in the holding frame 7 without using screws or the like.
Can be easily and completely installed.

Further, the dimensional error in the gap between the holding frame 7 and the cathode ray tube 5 is absorbed by the elastic force of the claw portion 3 of each hook 2.

Therefore, when attaching masks 1 of different shapes to the holding frame 7, the masks 1 can be attached to the same holding frame 7 by forming the hooks 2 at appropriate positions on the mask 1 without changing the shape of the holding frame 7.

That is, the holding frame 7 can be shared.

For example, when attaching American type and domestic type masks 1', 1'' having shapes as shown in FIGS. 5 and 6, if hooks 2 are formed at appropriate positions on each mask 1', 1'', They can be attached to the same holding frame I.

As described above, according to the mask mounting device for a television receiver of this invention, a plurality of hooks having protrusions are formed on the mask of the television receiver, and the protrusions of each hook are attached to the holding frame of the cathode ray tube. By attaching the mask and fixing the cathode ray tube to the holding frame, and by sandwiching each hook between the cathode ray tube and the holding frame, the mask can be easily and completely attached to the holding frame without using screws or the like. can reduce assembly man-hours.

Also, when attaching masks with different shapes,
By forming hooks at appropriate positions on the mask, the holding frame can be shared, the mold cost is reduced, and it is economical and productivity is improved.
