Description

[Detailed Description of the Invention] The present invention relates to a device for fixing a decorative frame to a panel surface of a box or the like of various electronic devices.

When attaching a decorative frame to the panel surface of the front opening of a box that houses various electronic devices (for example, the outer box of a television receiver), conventionally a decorative frame that matches the edge of the panel surface provided at the opening has been used. Measures are taken such as providing a groove in the decorative frame and fitting it together, or attaching a screw seat to the inside of the panel surface by spot welding or the like and fixing the decorative frame with screws.

However, with such means, there are defects such as wobbling in the attached decorative frame and gaps between the decorative frame and the panel surface of the box body, so it is not possible to securely fix the frame. Therefore, it was not desirable in terms of practical use or appearance.

Therefore, the present invention aims to improve the above-mentioned defects by providing a projecting edge on the back side of the decorative frame so as to form a stepped part of an appropriate height, and attaching a screw seat to the projecting edge with a set screw, and attaching the screw seat to the outer circumference of the screw seat. By fixing the decorative frame to the panel surface by sandwiching the edges of the panel surface with the stepped portion and the above-mentioned stepped portion, the decorative frame can be securely and closely fixed to the panel surface, and the appearance of the fixed state is also excellent. The purpose of this invention is to obtain a fixing device for a decorative frame.

Next, an embodiment of the present invention will be described with reference to the drawings. On the back surface of the decorative frame 1, a protrusion 3 is provided in an appropriate manner so as to form a stepped portion 2 of an appropriate height. A through hole 4 is bored in the hole.

Then, a set screw 5 is fitted into the through hole 4, and a screw seat 6 of an appropriate shape is screwed onto the set screw 5.

As shown in this embodiment, the screw seat 6 has an appropriate shape such as a square, rectangle, or oval. An appropriate gap is provided between the narrow portion W1 and the stepped portion 2 so that the edge 9 of the panel surface 8 of the box body 7 can be fitted therein.

The mounting position and number of screw seats are determined as appropriate depending on the size of the decorative frame, etc.

Next, as shown in FIGS. 1, 2, and 3, when the cathode ray tube 10 is mounted on the panel surface 8 of the opening of the box 7 housing the cathode ray tube 10, as in a television receiver, CRT display device, etc. As an example, box 7th panel surface 8
The decorative frame 1 configured as described above is applied to the box body 7 and the projecting edge 3 is
At the same time, the edge 9 of the panel surface 8 is fitted between the stepped portion 2 of the decorative frame 1 and the screw seat 6.

Next, when the set screw 5 screwed into the screw seat 6 is rotated and tightened, the screw seat 6 rotates accordingly (Fig. 4).
, the wide part W2 of the outer periphery hits the edge 9, and the edge 9 is pressed against the step 2 of the decorative frame 1, and when the screw 5 is further tightened, the edge 9 contacts the screw seat 6 and the step. The decorative frame 1 is clamped by the portions 2 and cannot be removed, and the decorative frame 1 is fixed to the panel surface 8.

Note that 1 and 1 in the drawings represent a chassis.

According to the present invention having the above structure and function, the edge of the panel surface is sandwiched between the stepped portion provided on the back side of the decorative frame and the screw seat attached to the protrusion, and the decorative frame is fixed to the panel surface. Because of this, the decorative frame and the panel surface are in close contact with each other and can be securely fixed, and the appearance is also excellent.

In addition, the structure is relatively simple and the set screws are easy to tighten, so compared to conventional means of attaching screw seats by spot welding, etc., assembly work does not require skill. It is possible to obtain effects such as reducing the number of assembly steps.
