Description

[Detailed description of the invention] The present invention relates to an operating member having an operating button made of a resin molded product at the free end of a band-shaped metal lever (flat bar), and particularly relates to an engagement structure between the flat bar and the operating button. This is a new design.

For example, tape recorders and various electronic devices are equipped with this type of operating member, and there are various means for attaching the operating button to the flat bar.

However, the common problems with the conventional methods are that there are some difficulties in the workability of attaching the operation button, and that it takes time to remove it from the flat bar when replacing the operation button.

The main purpose of the present invention is to improve the problems of the conventional operating member, such as tilting.

The present invention will be described below with reference to the drawings. FIG. 1 is an exploded perspective view showing one embodiment thereof.

In the figure, 1 is a band-shaped metal lever or flat bar, 2
This shows an operation button made of a molded synthetic resin material having a certain degree of elasticity, and as shown in the figure, it has a cubic outline, for example, and its front side is hollowed out and has a rectangular edge 3. A horizontal insertion groove 4 is formed in the center of this front surface for inserting the right free end of the flat bar 1.

In other words, the upper and lower parts of this insertion groove 4 are formed into ribs 5 and 6 of a predetermined thickness that reach the inner end of the hollowed out part (see Fig. 2), and the tongue piece 8 having, for example, a square hole 7 is formed from the upper rib 5. It is formed to protrude forward.

On the other hand, at the central position near the free end of the flat bar 1, hooked protrusions 9 are formed by pressing into a series of gently curved surfaces on the free end side, and are protruded to the left on the upper surface, and between the protruding end and the opposite side. The relief hole 10 is punched out and has a width dimension of .

The relationship between the width W and thickness t of the flat bar 1 near the free end and the width W' and interval t' of the insertion groove 4 is W≧W, t≧t'. It will be done.

With the above settings, if the free end of the flat bar 1 is inserted into the insertion groove 4 of the operating button 2 (light press fit), the tongue piece 8 of the operating button will follow the surface of the protrusion 9 at the two points in Figure 2. It is bent as shown by the chain line 7', and the square hole 7 of the tongue piece 8 finally engages with the protrusion 9, and the tip of the protrusion 9 prevents the operation button 2 from being removed.

That is, the flat parr 1 and the operation button 2 are in a completely engaged state, and the engagement operation can be performed only by pressing both relative to each other.

In addition, the above-mentioned escape hole 10 in this example is intended to be used when removing the operation button 2, and as shown in FIG. If a rod 11 as shown by the two-dot chain line is inserted into the relief hole 10 from below 1 and the tongue piece 8 is bent upward, it can be easily disengaged from the protrusion 9. 2
can be extracted relatively easily from flat par 1.

Thus, the advantages of the operating member of the present invention are already obvious, and together with the simple construction, its practical benefits are significant.

[Brief explanation of drawings]

FIG. 1 is an exploded perspective view showing an example of the operating member according to the present invention, and FIG. 2 is a longitudinal cross-sectional view showing its engaged state. In the figure, 1 is a flat par, 2 is an operation button, 4 is an insertion groove, and 7
8 is a square hole, 8 is a tongue piece, 9 is a protrusion, and 10 is a hole.

Claims (1)

[Scope of utility model registration request] In an operating member having an operating button made of a resin molded product at the free end of a band-shaped metal lever, the operating button is formed with an insertion groove that matches the shape of the free end of the lever, and the longitudinal side of the insertion groove is A tongue piece having a retaining hole is provided in a protruding manner, and on the other hand, the lever has a cut-and-raised part formed by press working, etc., and an escape hole that passes through the lever with a predetermined width on the free end side of the cut-and-raised part. Insert the free end of the lever into the insertion groove of the operation button, bend the tongue along the raised part, and insert the raised part into the engagement hole. The operating member is configured to engage the lever and the operating button with the free end of the tongue facing the escape hole.
