Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a push button mounting device used in electronic equipment such as television receivers.

(b) Prior Art In conventional television receivers, operation buttons such as a channel button and a volume button are usually divided into an up button and a down button, respectively, and are arranged close to each other. That is, a plurality of push buttons are arranged in a plurality of rows.

For example, push buttons arranged in this way are as follows:
As described in Japanese Patent No. 181137, two rows of push buttons (upper and lower rows) are configured so that they can be operated integrally and independently by a connecting portion placed in the middle of the push button groups.

In the conventional example described above, since the distance between the upper and lower rows of push button groups is relatively wide, it is possible to arrange a connecting portion in the middle, but this is not appropriate when the distance is narrow.

(c) Problems that the invention aims to solve This invention was created in view of the above points,
To provide a push button mounting device that can stably mount a plurality of push buttons with good operability even if the distance between the two rows is narrow when a plurality of push buttons are arranged in two rows.

(d) Means for solving the problem The present invention provides a push button which is arranged at the end of a mounting part attached to an operation panel and an elastic arm extending from the mounting part, and has a notch formed in its first surface. the first and second push buttons supported by the second and first surfaces of the push button support parts of the first and second push button bases, respectively; .

(e) Effects In the present invention, the elastic arm portion of the second push button base is located in the notch of the first push button base in a non-contact state by the above-described means.

(f) Embodiment An embodiment in which the present invention is applied to a TV receiver will be described below with reference to the drawings.

Fig. 1 is an exploded perspective view of the device of this embodiment, Fig. 2 is a rear view of the same in the assembled state, and Fig. 3 is A of Fig. 2.
-A' sectional view.

1 is the operation panel of the TV receiver, and this operation panel includes a recess 1a, a pair of slits 1b arranged in the recess and tapered so that the inside becomes wider, and adjacent to the slits. four locking pieces 1c, 1c..., a flat part 1d continuous to the recess, three first bosses 1e, 1e, 1e formed on this flat part and having a first height. , a first screw hole 1f formed in one of the three bosses,
first guide pins 1g, 1g formed on the other two bosses; three second bosses 1h, 1h, 1h having second heights lower than the first boss;
The screw hole 1i is formed in one of the screw holes 1i, and the second guide pins 1j, 1j are formed in the other two.

2, 2 is a push button base, and the push button base is
A mounting base 2a to be attached to the operation panel, a first through hole 2b arranged in this mounting base, two second through holes 2c, 2c arranged on both sides of this first through hole,
Four thin elastic arm portions 2d, 2d extend from the mounting base, and a pair of push button support portions 2e, 2e are arranged to connect the tips of two adjacent elastic arm portions, respectively. , the push-button support portion is composed of through-fitting holes 2f, 2f formed at both ends thereof, and notches 2g, 2g formed adjacent to the through-fitting holes. In this push button base, the elastic arm, the mounting base, and the push button support are flush with each other on the first surface, and the notch is formed on the second surface opposite to the first surface.

3, 3... are push buttons supported by the push button support part 2e, and the fitting through holes 2f, 2f.
A pair of support shafts 3a, 3a that fit into the holder and a projecting piece 3b that can be engaged with the locking piece 1c of the operation panel are integrally molded.

Next, the assembly of the device of this embodiment will be explained.

First, in FIG. 1, the support shafts 3a, 3a, etc. of the push buttons 3, 3 are inserted from the second surface side into the fitting through holes 2f, 2f, ... of the push button base 2, with the first surface facing upward, and fitted. urge At this time, the protrusions 3b, 3 of the push button
b are fitted so that they face upward in FIGS. 2 and 3, respectively. And, the second button based on this push button
The second guide pin 1 of the operation panel is inserted into the through holes 2c, 2c.
The push button base is fixed to the operation panel by inserting the screws 4 through the first through holes 2b and into the second screw holes 1h. This causes the tip of the push button to form the slit 1b.
located within.

Next, the support shafts 3a, 3a, . . . of the push buttons 3, 3 are inserted from the first surface side into the fitting through holes 2f, 2f, . . . of the push button base 2 with the second surface facing upward, and are fitted. At this time, the protruding pieces 3b, 3b of the push button are fitted so as to face downward in FIGS. 2 and 3, respectively. Then, the second through holes 2c, 2 of this push button base
Insert the first guide pins 1g and 1g through the first screw hole 1 through the first through hole 2b and insert the screw 4 into the first screw hole 1 through the first through hole 2b.
Fix by aligning bases at f. As a result, the tip of the push button is positioned within the slit 1b.

In this state, the two push button bases 2, 2 have different installation heights from the operation panel 1 and have a predetermined step difference, but this difference approximately corresponds to the thickness of the push button support part 2e, and The mounting heights of the push buttons 3, 3, . . . supported by the operation panel are the same. Therefore, the amount of protrusion of each push button from the operation panel is constant.

Incidentally, in this state, each push button support section 2e, 2e, . . . and the switch body (not shown) are made to face each other, thereby completing the assembly. When the switch bodies face each other, the push button 3 is biased to the left in FIG. Since the push button 3 is locked to the piece 1c, the push button 3 is restricted to the illustrated position.

In addition, in FIG. 3, the elastic arms 2d, 2d, . . . of the push button base 2 located above are located within the notches 2g, 2g, . Even if you operate
The elastic arm portion and the notch are held in a non-contact manner.

With the above-described configuration, each of the push buttons 3, 3, . . . can be independently pressed by elastic deformation of the elastic arms 2d, 2d, .

In the above-mentioned embodiment, a predetermined step is provided between the first and second bosses 1e and 1h for attaching the attachment part 2a, but by making the attachment part the same shape as the push button support part 2e, 1st boss 1e to 2nd boss 1
It can be formed at the same height as h.

Furthermore, by attaching the pushbutton to the pushbutton support and attaching the attachment to the operation panel using the same method, the attachment of the pushbutton base and the pushbutton support can have a symmetrical structure, making it easier to attach the pushbutton. It can be attached to either the push button support section or the push button support section, improving assembly work efficiency.

(g) Effects of the invention As described above, according to the invention, the push button bases that support the push buttons of each row are arranged so as to overlap in the same direction, so that the installation space can be reduced.

Further, since notches are formed in the push button support portions of one row and the push buttons are held in a non-contact manner with the elastic arm portions of the other row, the operations of the push buttons do not interfere with each other.

Furthermore, since the push button bases in each row have the same shape, the operating feel of each push button is uniform.
