Description

[Detailed description of the invention] The present invention relates to a button switch mechanism, in particular a seesaw system that uses the elastic force of the front panel made of synthetic resin etc. to automatically return to its original position after a pressing operation. Regarding the button switch mechanism.

In general, a seesaw type button switch mechanism is normally used, as shown in FIGS. 1 and 2. As shown, it is cut out symmetrically into a U-shape, thereby first forming a rotating part 1 and hinge parts 2 and 3 as a switch pressing part. When the rotating part 1 is pressed in the direction A or B in FIG. 2, the elastic force of the rotating part 1 and the hinge parts 2 and 3 facilitates automatic return of the rotating part 1 to its original position. The structure is as follows. Here, reference numeral 4 indicates a decorative button, and 4A and 4B indicate protrusions for locking the decorative button 4 to the rotating portion 1. Further, a press switch (not shown) is disposed on the back surface of the rotating end of the rotating portion 1 (positions C and D in the figure).

However, in the above-mentioned conventional example, when the operator presses the approximate center of the decorative button 4, the entire hinge portions 2 and 3 are pressed in a concave shape, which causes a twisting effect other than the normal operation. The hinge parts 2 and 3 are subjected to bending and stretching, and as a result, fatigue progresses rapidly.
The drawback was poor durability.

An object of the present invention is to improve the disadvantages of the prior art and to provide a button stitching mechanism that is simple in structure and has excellent durability.

Therefore, the present invention has a substrate that supports the rotation operation section through the hinge section, the substrate, the hinge section, and the rotation operation section are integrally molded from a resin material, and the outer surface of the rotation operation section is In a seesaw-type button switch mechanism equipped with a decorative board, the outer periphery of the decorative board extends toward the board, and there is an overall uniform gap between the extended part of the decorative board and the board. A configuration is adopted in which a space is provided and a rotating fulcrum part for the decorative board is provided in a portion of the extended part of the decorative board located outside the hinge part that protrudes toward the board and comes into contact with the board. The aim is to achieve the above-mentioned objectives by:

The first embodiment of the present invention will be described below in Figures 3 to 4.
This will be explained based on the diagram.

In these figures, numeral 10 indicates a substrate;
Reference numeral 11 indicates a rotation operation portion formed in a rectangular shape. The rotation operation portion 11 is surrounded by a cutout portion formed by a combination of two U-shaped notches 12 and 13, similar to the conventional example described above. The rotation operation section 11 further has hinge sections 14 and 15 formed at the center on both sides thereof, and is supported by the base plate 10 via the hinge sections 14 and 15. In addition, the rotation operation section 11
is integrally formed of the same material with the substrate 10 as a resin escutcheon and the hinge portions 14 and 15 integrated therein, and furthermore, its thickness slightly protrudes upward from the thickness of the substrate 10. It has a thickness of

A decorative plate 20 is attached to the outer surface of the rotation operation section 11. This decorative board 20
In this embodiment, the periphery of the aforementioned rectangular rotation operation portion 11 is extended toward the outer periphery as a whole, and the portion of this extended outer periphery 20A is 14 and 15 of the hinge part mentioned above
Half-column-shaped protrusions 21 and 22 having a function as a rotation fulcrum for the decorative board are provided on the outside of the part facing the decorative board. The decorative board 20 also includes spacer legs 20B for mounting on the back side thereof.
20C is formed, and this spacer leg 20
The decorative plate 20 and the rotating operation section 11 are integrated with each other via B and 20C. Also,
This rotation operation part 11 has through holes 1 for spacer legs 20B and 20C for attaching the decorative board 20.
1A and 11B are formed.

Furthermore, press switches S ₁ and S ₂ which are turned on and off by the rotation operation of the rotation operation section 11 are respectively arranged on the rotation direction side of the rotation operation section 11 as shown in FIG.

In the first embodiment configured in this way, when the extending portion 20A of the decorative board 20 is pressed in the direction of arrow P (or Q) in FIG.
, the protrusions 21 and 22 are connected to the support part 1 on the substrate.
It is supported by 0A and 10B and rotates as a whole in the direction of arrow A (or B), thereby pressing switch S ₁ (or S ₂ ). In this case, the hinge portion 14,
Reference numeral 15 only receives a slight twisting action within the elastic limit from the rotating operation part 11, and other external forces (for example, pressing force) are received by the substrate 10 via the support parts 10A and 10B.

Therefore, since the hinge parts 14 and 15 can easily return to their original positions, the durability of the hinge parts 14 and 15, that is, the durability of the button switch mechanism as a whole, is significantly improved. Since the structure allows the size of the decorative board 20 to be formed relatively large, the decorative board 2
0 can cover the entire U-shaped notches 12 and 13 of the substrate 10, and therefore has the advantage that it can function satisfactorily as a pure decorative board.

Next, a second embodiment will be explained based on FIGS. 5 and 6.

In this embodiment, the rotation operation part 11 in the first embodiment described above is made to have the same thickness as the substrate 10, and the center part of the lower surface side of the decorative board 20 in the same figure is arranged to face the rotation operation part 11. The decorative plate 20 and the rotating operation part 1 are formed somewhat thickly as shown in FIG.
1 can be rotated sufficiently in the direction of arrow A (or B). The other configurations are the same as those of the first embodiment described above.

Even in this case, in addition to having the same advantages as the first embodiment described above, there is an advantage that the formation of the substrate 10 and the rotation operation part 11 is facilitated, and the mold for molding can be simplified overall. .

In addition, in each of the above embodiments, the decorative board 20,
Although a rectangular shape is used as 29, the present invention is not necessarily limited to this, and may be circular or other polygonal shapes, for example.

As described above, the present invention has a substrate that supports the rotation operation section via the hinge section, and the substrate, the hinge section, and the rotation operation section are integrally molded from a resin material, and the rotation operation section is In a seesaw type button switch mechanism in which a decorative board is attached to the outer surface of the part, the outer periphery of the decorative board is extended toward the board, and the entire part is placed between the extended part of the decorative board and the board. A uniform gap is provided, and a rotating fulcrum part for the decorative board is provided in the extended part of the decorative board located outside the hinge part, and projects toward the board and comes into contact with the board. Therefore, due to the effect of the decorative laminate and the rotation fulcrum for the decorative laminate, external forces such as bending are hardly applied to the hinge portion that supports the rotation operation portion, and this reduces the durability of the hinge portion, i.e. It has become possible to significantly increase the durability of the entire switch mechanism, and this can be done simply by changing the decorative plate.Therefore, the purpose can be achieved at a relatively low cost without reducing productivity, which is an unprecedented practical application. A see-saw button switch mechanism can be provided.
