Description

[Detailed Description of the Invention] The present invention relates to a mounting device for a cathode ray tube in a television receiver, etc., and uses a cylindrical mounting device that can accommodate the funnel surface of the cathode ray tube to connect the cathode ray tube to the cabinet. When the cathode ray tube is clamped and fixed to the tube, variations in dimensions of the cathode ray tube can be easily absorbed and mounted.

The conventional mounting device of this type is as shown in Fig. 1 a, l).
A substantially cylindrical fixture 2 having a shape that matches the funnel surface of the cathode ray tube 1 and capable of housing this funnel surface.
Using this, place this fixture 2 over the cathode ray tube 1 located on the cabinet 3 from the rear, and then attach it to the boss 4 of the cabinet 3.
By fixing with screws 5, the cathode ray tube 1 was sandwiched and fixed between the fixture 2 and the cabinet 3.

However, in this case, due to dimensional variations in the cathode ray tube 1, the shape of the fixture 2, especially the shape of the contact surface, becomes extremely complicated, and a gap inevitably occurs between the fixture 2 and the cathode ray tube 1, causing the cathode ray tube 1 to wobble even after installation. There were drawbacks such as the difficulty of relaxing and inserting the cathode ray tube into the fixture.

The present invention eliminates the above-mentioned conventional drawbacks.

An example of this will be described below with reference to FIGS. 2 and 3.

Fig. 2 a, l) shows that the mount 10 is attached to a cathode ray tube (
The funnel surface (not shown) is formed into a substantially cylindrical shape that can accommodate the funnel surface, and a hole 11 is formed in the bottom surface through which the neck portion of the cathode ray tube is inserted. A pair of recesses 12 are formed to face each other, and a reinforcing rib 13 in the form of a narrow strip is integrally installed between opposing edges of the recess 12.

The reinforcing ribs 13 here are formed in a straight line.

Therefore, if the fixture 10 is formed to be relatively small in consideration of the dimensional variations of the cathode ray tube, when the cathode ray tube is housed in the fixture 10, the fixture 10 will be bent by the recess 12, and the shape of the cathode ray tube will be Despite the large
Furthermore, even if the shape of the fixture 10 does not exactly match the shape of the cathode ray tube, it can be accommodated.

At this time, the reinforcing rib 13 stretches for a moment due to its material and returns to its original state again.
Even though it is formed, the strength of the fixture 10 can be maintained at the same level as that of the conventional product.

FIGS. 3a and 3l) show another embodiment of the present invention, and the difference from FIG. 2 is that the reinforcing ribs 13', 13''
．． 12", reinforcing ribs 13', 13
” is made to stretch due to its shape.

Of course, the reinforcing ribs 13, 13'' are provided within the recess.

Although a pair of recesses 12 are provided in each of the above embodiments, it is sufficient to provide at least one recess 12, and the position of the recess 12 is also determined since the contact surface of the fixture 10 with the cathode ray tube is the funnel surface. Although it is formed at the rear end of the fixture 10 so as to be continuous with the hole 11, it may be provided at the front opening side.

Further, various shapes of the reinforcing ribs other than those in the embodiments can be considered.

In FIG. 2, 14.14 is a pair of mounting pieces, each having a hole 15.15 through which a screw (not shown) is inserted.
0 is fixed to a cabinet (not shown) using the mounting pieces 14, 14 and screws as in the case of FIG. 1, and the cathode ray tube is held between the cabinet and the cabinet.

As explained above, according to the present invention, a notch recess is provided in a part of the fixture to give the fixture flexibility, and opposing edges are joined by sandwiching the notch recess within the notch recess. By providing reinforcing ribs in the form of narrow strips, the shape of the fixture can be manufactured with less precision than before, and the cathode ray tube can be stored and held without wobbling regardless of the size variation of the tube. This has the advantage that the strength of the fixture itself does not deteriorate despite the provision of the notch recess.
