Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a push button structure of an electronic device such as a video tape recorder (VTR).

[0002]

2. Description of the Related Art A conventional push button structure will be described with reference to FIG. In the figure, a button 1 is connected to a mounting base 3 via two hinge ribs 2 and 2 and is integrally formed. Reference numeral 3a is a through hole for attachment. Reference numeral 1'denotes another push button connected to the mounting base 3 via the hinge rib 2 '.

Compared with the miniaturization of the set body, the size of the push button tends to be large in order to improve the operability. Therefore, the space between the push button 1 and the mounting base 3 is designed to be as narrow as possible, and the length of the hinge rib 2 is designed to be short.

[0004]

When the push button 1 described above is pressed, the feeling of operation varies depending on the position where the button is pressed, and particularly when the part near the hinge rib 2 is pressed, the feeling of operation becomes heavy. . Further, as shown in FIG. 4 (b), if the end portion of the button 1 is forcibly pushed, the hinge rib portion 2a on the opposite side is twisted.

[0005]

In view of the above, in the present invention, a plurality of buttons formed in a frame and a base having a pedestal facing the adjacent boundary of the plurality of buttons are used as a two-point structure, and the plurality of buttons are provided. The button has a multiple push button structure that is connected to the frame body through a hairpin curved hinge rib. Further, the hinge ribs are provided at both ends of the long diameter portion of each button. Furthermore, when the button is pressed, the elastic piece that comes into contact with the button is integrally formed with the base.

[0006]

With the above-described structure, no matter what part of the large push button is pressed, especially when pressing the end part, the feeling during operation is averaged and no discomfort is felt.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A specific embodiment of the present invention will be described below with reference to the drawings. 1 is an exploded perspective view of the appearance, FIG. 2 is a sectional view, and FIG. 3 is a perspective view of the appearance showing a push button operation state. In the figure, push buttons 4, 5 and 6 are attached via a pair of hinge ribs 7, 7, 8, 8, 9, 9 respectively to a frame 10 for mounting.
, And is integrally molded with synthetic resin to form a multiple push button body 11. Through holes 10 for attachment to the frame body 10
a, 10a, ... Are provided. Reference numeral 12 is a base integrally formed with an inverted Y-shaped pedestal 13 and elastic pieces 14, 14 ... In the base 12, through holes 12a, 12a, 12a and through holes 12b, 12b for mounting are provided. ing. The switch pressing piece 4 of the push buttons 4, 5, 6 is provided in the through hole 12a.
a, 5a, 6a are inserted. The front panel 15 includes a push button fitting hole 15a and mounting bosses 16, 16
... is formed.

As shown in FIG. 2, the through holes 10 of the multiple push button body 11 are formed in the bosses 16, 16 ... of the front panel 15.
a and 10a ... and through holes 12b, 12b ...
Are opposed to each other. In this state, the pedestal 13 of the base 12
Are arranged so as to oppose the adjacent boundary portions A, B, C (see FIG. 1) of the buttons 4, 5, 6 with a gap of the push button stroke g. Further, the elastic pieces 14, 14 ... Of the base 12 are
It abuts and faces the bottom surface of the skirt 6b of the button 6.

The present invention is characterized by the shape of a pair of hinge ribs 7, 8, 9 which connect the buttons 4, 5, 6 to the frame body 10. The hinge ribs 7, 8 are, as shown, the buttons 4, 5, 5.
It is formed symmetrically from both ends of the major diameter portion along the outer circumferences of the buttons 4 and 5 via the hairpin curved rib portions 7a and 8a, respectively. This is because the hinge ribs 7 and 8 are formed as long as possible to disperse the strain at the time of pressing.

Now, when the portion of the button 4 near the base of the hinge rib 7 is pushed, the hairpin curved portions 7a, 7a extend and the button 4 performs substantially parallel movement (see FIG. 3).
The feeling of operation is good. Also, the adjacent border A of the button 4
Alternatively, when the portion B is pushed, the hinge ribs 7, 7 are not twisted.

On the other hand, when the buttons 6 of different sizes are arranged side by side, if the hinge ribs of the same shape are used, the operation feeling of the large button 6 may be lighter. In such a case, elastic pieces 14, 14 ... For elastically holding the skirt portion 6b are brought into contact with the large button 6 to align the pressing operation feeling with the other small buttons 4, 4. You can In that case, a pair of hinge ribs 9 and 9 is formed from a portion of the elastic pieces 14 and 14 which contacts the middle, and hairpin curves 9a and 9a are provided like the other buttons 4 and 5.

[0012]

As described above, in the button structure of the present invention, even if the distance between the button portion and the frame portion is narrowed, the hinge rib is formed in a hairpin curve shape so that substantially the same operation can be performed regardless of where the button is pressed. You can feel it. Further, in the case of another continuous button body having a different size, by making the large elastic button contact the auxiliary elastic piece with respect to the large button, it is possible to make the feel of each button substantially uniform.
