Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a push button device used in electrical equipment, etc.

(B) Prior art In general, in devices in which a plurality of push buttons are arranged to protrude in series through an opening provided on one side of the housing, for example, on the front panel, the amount of protrusion of each push button from the front panel varies depending on the parts. In the case of push-button push-buttons, if the hinges come apart due to fatigue, it would be very unsightly, so a method is used in which all the push-buttons are crimped to the front panel side. Conventionally, this method involves crimping individual push buttons with spring coils, but such a method requires as many spring coils as there are push buttons, and requires the same amount of man-hours for assembly. There is also a method of crimping with a spring plate, but this also requires parts, which inevitably increases costs.

(c) Purpose of the invention In view of the above, the present invention proposes a push button device that eliminates the above-mentioned drawbacks.

(d) Embodiment of the invention FIGS. 1 to 4 are diagrams showing an embodiment of the push button device according to the invention.

In Fig. 1, 1 is the first substrate constituting the housing, for example, a front panel made of synthetic resin, 2 is a recess provided in the front panel 1, and 3, 3 are integrally provided in the front panel 1. Elastic operation section, 4 is a second substrate constituting the housing, for example, a decorative plate made of synthetic resin; 5 is an opening provided in the decorative plate 4; 6, 6 are push buttons made of synthetic resin; each push button is connected to the main body; Portion 7 is opening 5 of decorative plate 4
A fixing portion 8 at one end is fixed to a boss 9 on the inner surface 24 of the decorative plate 4 with a screw 10 so as to project outward through the plate. Reference numeral 11 designates a thin hinge portion provided on each push button, and reference numeral 12 represents a locking portion provided at the other end of each push button.
The decorative plate 4 to which the push buttons 6, 6 are fixed is attached to the front panel 1.
It is fixed to the front panel 1 with screws 13, 13 to cover the recess 2. At this time, the elastic operating section 3 disposed inside the decorative plate 4 integrally provided on the front panel 1 presses and biases the locking part 12 of the push button 6 against the inner surface 24 of the decorative plate 4. 14 is a chassis made of synthetic resin, and the front panel 1 is fixed to this chassis 14 with screws (not shown). 15 is a printed circuit board fixed to bosses 16, 16 provided on the chassis 14 with screws 17, 17; 18, 18 are interlocking push switches for switching functions attached to the printed circuit board 15; 22 is an operator for each push switch. By operating the push button, only one of the plurality of push switch operators is locked in the pressed state (ON state).

Although not shown in FIGS. 1 to 4, which push switch is set to the ON state may be displayed using a display means such as a light emitter.

19 is a rotary switch attached to the printed circuit board 15, and 20 is an operating knob of the rotary switch 19.

By the way, if a special printed circuit board is used for mounting the push switch, the push button and the push switch can be brought closer together. Therefore, in this case, it is conceivable to directly operate the push switch using a push button. However, if a dedicated printed circuit board is used to mount the push switch, the number of parts will increase, and workability such as wiring lead wires with other printed circuit boards will become worse. Therefore, it is not preferable to use a dedicated printed circuit board for mounting the push switch.

On the other hand, when a push switch and other parts are mounted on a single printed circuit board, as is clear from FIG. The push button 6 and the push switch 18 become separated. Therefore, press button 6
It is not possible to directly switch the push switch 18, and a means for operating the push switch 18 is required between the push button 6 and the push switch 18.

Therefore, in the present invention, the push button 6 is moved to the inner surface 2 of the decorative plate 4.
The elastic operation section 3 that presses and biases the push switch 18 also serves as an operation means for the push switch 18.

Furthermore, as is clear from FIG. 3, the elastic operating section 3
The height of the vertical part 21 is the height of the rotary volume 19.
etc. determined by the dimensions between the front panel 1 and the printed circuit board 15 in relation to the components mounted on the printed circuit board 15.

In the push button device configured in this way, the push button 6
When not being pressed, the elastic operating section 3 moves t with the hinge section 25 as a fulcrum, as shown in FIG.
It is only flexing. For this reason, an elastic return force acts on the elastic operating portion 3, and this elastic return force urges the locking portion 12 of the push button 6 against the inner surface 24 of the decorative plate 4. Therefore, there is no variation in the protrusion of the plurality of push buttons 6, 6 that protrude in series through the opening 5 of the decorative plate 4.

On the other hand, as shown in FIG. 4, when the push button 6 is pressed against the elastic force of the elastic operation piece 3, the elastic operation section 3 rotates about the hinge section 25, and the elastic operation section 3 switches the push switch 18. operator 22
Press to switch the push switch 18.
After that, when the pressure on the push button 6 is released, the elastic operation section 3 returns to its elastic state, and the engaging section 12 of the push button 6 is pressed against the inner surface 24 of the decorative plate 4 again.

By the way, in the case of a synthetic resin push button equipped with a hinge part, especially if the surface of the push button is plated with metal, if the push button is repeatedly pressed, the hinge part may wear out due to metal fatigue of the plating. This is intense and causes variations in the amount of button presses. Therefore, in the case of this embodiment, even if the hinge part 11 of the push button 6 becomes loose, the elastic operating piece 3 provided on the front panel 1 is used to compensate for this, so that the protrusion of the push button 6 does not vary. I have to.

FIG. 5 is a diagram showing another embodiment of the present invention.
In the push button device shown in FIG. 5, the main body 7' and the locking part 1
One end of a push button 6' having a push button 2' is pivotally connected to a decorative plate 4' by a rotating shaft 23. The other configurations are the same as in FIGS. 1 to 4. Also, in the push button device shown in FIG. 5, the elastic operation section 3 provided on the front panel absorbs the vertical play of the push button 6', thereby preventing variations in the protrusion of the push button 6'.

In both the embodiments shown in FIGS. 1 to 4 and the embodiment shown in FIG. 5, a decorative plate is used, and the push button is made to protrude outward through an opening provided in the decorative plate. The present invention is not limited to this embodiment, and an opening may be provided in the front panel itself without using a decorative plate, and the push button may be made to protrude outward through this opening.

Furthermore, in the embodiments shown in FIGS. 1 to 4 and the embodiment shown in FIG. However, for example, a movable part of a mechanical component disposed on a mechanical board of a tape recorder may be operated by pressing.

Further, in the embodiments shown in FIGS. 1 to 4, an example in which two pushbuttons are arranged in a row is explained, but the present invention is not limited to such embodiments, but can also be applied to devices in which three or more pushbuttons are arranged in a row. Needless to say, it can also be applied to

(E) Example of the invention As described above, according to the invention, there is no need to use special parts to prevent variations in push button protrusion, so parts costs and man-hours can be reduced. I can do it.
