Description

[Detailed description of the invention] This invention is a device that attaches a rotating lever connected to a knob that rotates with several moderations, like a band selector or function selector used in audio equipment, to a structure such as a chassis. Regarding.

A conventional device is shown in FIGS. 1 and 2. In the figures, a lever 1 is attached to a structure 4, and a lever presser 2 with an elastic claw 7 is placed on top of the lever 1, and the elastic claw 7 is attached to the structure 4. It was inserted into hole 9 and fixed with screw 3.

This prevents the lever 1 from coming off.

Although this method is labor-intensive, it requires a large number of parts to be installed, resulting in high costs and a large number of man-hours.

The object of the present invention is to provide a lever mounting device with a simple structure that reduces cost and man-hours.

In the present invention, the lever is provided with an elastic pawl and a moderation part, and an arc-shaped guide with a large hole in a part and a moderation body facing the above-mentioned moderation part are provided in the horizontal body corresponding to the claw, and the lever is Attachment to the structure is done by inserting an elastic claw into the large hole. At this time, the lever is placed in an intermediate position without moderation, and the elastic claw does not come off in the normal guide position to prevent the lever from coming off. It is something.

The present invention will be explained in detail below with reference to embodiments shown in FIGS. 3 to 7.

As shown in FIG. 3, the lever 1 is provided with a pair of elastic pawls 8 and a plurality of recesses 6 for generating moderation, and protrusions 10 are provided on both sides of the recess 6.

Note that 1a is a rotating shaft.

On the other hand, the structure 4 has a convex portion 1 for moderation generation, as shown in FIG.
1 and a shaft portion 4a into which the shaft 1a is fitted.
An arc-shaped guide hole 9 having a large hole 9a in a part is provided.

The guide hole 9 has a large hole 9a in which the elastic claw 8 is inserted, and the width thereof is larger than the width a of the claw 8.

The width C of the other guide holes 9 is set smaller than the width a of the claw 8.

A sectional view of the lever 1 shown in FIG. 5 attached to the structure 4 is shown.

As shown in FIG. 6, when attaching the lever 1 to the structure 4, align the elastic claw 8 with the large hole 9a of the guide hole 9,
At this time, the convex portion 10 of the lever 1 is attached while bending the elastic piece 5 from the broken line to the solid line.

As shown in FIG. 7, when the lever 1 is in the moderation position, the convex part 11 of the elastic piece 5 matches the concave part 6 of the lever 1,
The elastic pawl 8 is located at a width C of the guide hole 9, and prevents the lever 1 from coming off from the structure 4.

Although the lever 1 is rotatable, the concave portion 6 and the convex portion 11 of the elastic piece 5 are always in the same position (moderation position) to prevent the lever from coming off.

The structure according to the present invention eliminates the need for the lever holder of the prior art and also eliminates the need for screws.

As described above, the present invention exhibits remarkable effects in terms of cost reduction and reduction in installation man-hours.
