Description

[Detailed Description of the Invention] This invention relates to a mounting structure for a dial cover that is attached to a radio receiver such as a car radio.

As a conventional dial cover mounting structure, there is one shown in FIG. 1, for example.

In the figure, reference numeral 1 denotes an equipment casing of a radio receiver, and a front panel 1a of this equipment casing 1 is provided with a window hole 1b for arranging a dial. The window hole 1b is the running area of the dial pointer 2,
A dial plate 3 is arranged facing this window hole 1b. 4a and 4b are operation axes for tuning operation, volume adjustment, etc., respectively.

A dial cover 5 is attached to the window hole 1b. The dial cover 5 is manufactured by punching or cutting, and a transparent part 5a is provided at the center by fitting or the like, and mounting holes 6, 6 are bored at both sides. Then, screws 7, 7 are inserted through these mounting holes 6, 6.
It is attached and fixed to the front panel 1a by a stopper as described above.

However, in this conventional dial cover mounting structure, since it was attached to the front panel 1a by screws 7, 7, the installation work was relatively troublesome, and the number of man-hours required for tightening the screws 7, 7 was relatively high. is applied, and the dial cover 5
Since two separate screws are required, parts management is troublesome and costs are high.

This idea was created by focusing on these conventional problems, and has hook pieces and inverted U-shaped hooks on both sides of the back side of the dial cover, and on the other hand, on the front panel side. A cutout portion is provided on both inner edges of the dial arrangement window hole, and the hooking piece is inserted into and guided to be hooked to the back surface of the front panel, and the hooking portion is hooked to the hooking portion. It is an object of the present invention to solve the above-mentioned problems by providing a plate-like protruding piece.

This idea will be explained below based on the drawings.

In each of the figures following FIG. 2, the same or equivalent members or parts as shown in FIG.

FIGS. 2 to 10 are diagrams showing an embodiment of this invention.

First, to explain the configuration, in this idea,
The dial cover 15 is made of a plastic molded product, and has a transparent part 1 as shown in FIGS.
5a, and a frame portion 15b colored black as an example.
are formed by two-color molding. A hook-shaped hook piece is provided on one side of the back side of the dial cover 15 manufactured in this way, and is bent slightly backward, and the other side is provided with a hook-shaped hook piece that protrudes toward the rear and is viewed from the front. A clamping part 12 is provided which has an inverted U-shape and has a retaining part 12a that prevents it from falling off in the forward direction. As will be described later, the retaining portion 12a is engaged with the back side of the front panel 1a to have a retaining function.

On the other hand, as shown in FIGS. 5 and 6, the above-mentioned latching pieces 11 are inserted and guided into both inner edges of the dial installation window hole 1b drilled in the front panel 1a, and the latching pieces 11 are inserted and guided. A first notch 1c for hooking the piece 11 to the back surface of the front panel 1a, and a plate-like protrusion 1d serving as a clamped part to be clamped to the clamping part 12 are provided. The plate-like protruding piece 1d is bent to the back surface side in a cut-and-raised shape. Also, this plate-shaped protrusion 1
A second notch 1e into which the clamping portion 12 is inserted and guided is bored in the upper part of d in FIG. 13 is a stopper.

Next, the front panel 1a of the dial cover 15
The installation and operation will be explained below.

First, when installing, as shown in FIGS. 7 and 8, the hooking piece 11 is inserted into the first notch 1c while tilting in the front-rear direction with respect to the device housing 1, and
Next, while tilting the dial cover 15 in the front-back direction, this time tilt it in the vertical direction, that is, lift the left side in FIG.
2 is positioned in the second notch 1e that guides the insertion, and then the first notch 1c side is the center of rotation, and the left side in FIG. It should be horizontal to the front and back direction. Through this series of operations, the plate-like protrusion 1d is pushed into the inverted U-shaped clamping portion 12 and clamped.

By such an attachment operation, the dial cover 15 is attached to the front part of the dial installation window hole 1b, as shown in FIGS. 9 and 10.

In this attached state, the dial cover 15 has the hooking piece 11 at the notch 1c on the side of the hooking piece 11.
The locking piece 11 is locked against the rear surface of the front panel 1a to prevent movement in the right direction and the vertical direction in FIG.

On the other hand, on the clamping part 12 side, the clamping part 12
The plate-shaped protrusion 1d is fitted and locked inside, as shown in Fig. 10, left.
Movement to the right and downwards is restricted. Further, as described above, the retaining portion 12a is attached to the front panel 1.
It abuts and locks on the back surface of a to prevent it from coming off.

Thus, the dial cover 15 is fixed to the dial mounting window hole 1b.

Next, FIGS. 11 and 12 show another embodiment of this invention.

In this other embodiment, a stopper 14 for preventing the dial cover 15 from sliding upward is provided on the back surface of the dial cover 15 at an upper portion on the side where the hooking portion 12 is disposed. This stopper 14
is fixed to the edge of the window hole 1b.

By providing this stopper 14, the dial cover 15 is more firmly attached and fixed to the front panel 1a. 16 is a recess provided in the front panel 1a, and by providing this recess 16,
When removing the dial cover 15, insert a screwdriver etc. into the recessed part 16 and remove the stopper 1.
4. Release the locked state.

Note that in the above embodiment, the dial cover 15
Although the central portion of the transparent portion 15a is assumed to be a transparent portion 15a, a dial scale may also be attached to this transparent portion 15a.

As detailed above, according to this invention, a hook piece and an inverted U-shaped hook are provided on both sides of the back side of the dial cover, and on the other hand, both sides of the window hole for dial placement are provided on the front panel side. Since the inner edge is provided with a notch portion into which the locking piece is inserted and guided so that the locking piece is hooked on the back surface portion of the front panel, and a plate-shaped protrusion piece that is clamped in the clamping portion, There is no need for any separate mounting parts such as screws as in the past, which not only reduces the number of parts but also eliminates the number of man-hours required to manage them, resulting in cost reduction.

Furthermore, with the above configuration, when installing,
Not only can it be attached to the front panel with a single touch without the use of tools, but it can also be fixed securely by restricting movement in the vertical and horizontal directions after installation, making it extremely suitable for industrial use. This is a new idea.
