Description

TECHNICAL FIELD The present invention relates to a push button device used in an in-vehicle radio, an in-vehicle disc reproducing device, an in-vehicle magnetic recording / reproducing device, and the like.

2. Description of the Related Art FIGS. 8 to 10 show a seesaw switch of a conventional vehicle audio device. This seesaw switch is used, for example, as a switch for increasing or decreasing the tuning frequency of a radio. In FIGS. 8-10, 14 is a front panel of the vehicle audio device,
The front panel 14 has a hole 15 into which a push button is inserted. Reference numeral 16 denotes a push button, and projecting pieces 17 for driving the switch are integrally formed on the left and right rear surfaces of the push button 16. Reference numeral 18 denotes a shaft integrally formed at the center of the rear surface of the push button 16. Reference numeral 19 denotes a groove-shaped bearing portion formed at the hole edge portion of the hole 15 of the front panel 14, and the shaft 1 of the push button 16 described above.
8 is inserted in the bearing portion 19. Reference numeral 20 denotes a light guide plate screwed to the rear surface of the front panel 14, which guides light from a light source (not shown) to the back surface of the push button 16 and illuminates the push button 16 from the back surface. The shaft 18 of the push button 16 is pressed from the rear by the light guide plate 20, and the shaft 18 is fixed to the front panel 1.
It is prevented from coming off from the bearing portion 19 of No. 4. Reference numeral 21 denotes a substrate arranged after the light guide plate 20.
The switch 22 is fixed to. The protrusion 17 of the push button 16 penetrates the hole of the light guide plate 20 and is in contact with the operation portion of the switch 22.

In the above-mentioned conventional example, when the right side or the left side of the front surface of the push button 16 is pressed, the push button 16 rotates about the shaft 18 as a fulcrum, and the push button 1
The projecting piece 17 provided integrally with 6 pushes the operating portion of the switch 22 to perform switching.

SUMMARY OF THE INVENTION However, the above-mentioned conventional push button device has a problem that the push button 1
6 must be inserted from the rear side of the front panel 14, and the light guide plate 20 must be screwed,
The assembly work was complicated.

The present invention is to solve the above-mentioned conventional problems, and the push button can be incorporated from the front side of the front panel.
A push button device that can be easily assembled is provided with a simple structure.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention forms a protrusion and a hook in a concave portion of a panel, and a small groove that engages with the protrusion and an arc-shaped edge portion around the small groove. A hole having a hole is provided in the push button, the arc-shaped edge of the hole of the push button is engaged with the hook to prevent the push button from being pulled out, and the push button is rotatably supported with the projection as a fulcrum. It is a thing.

The present invention has the above-described structure, and the push button is inserted into the concave portion of the panel, the small groove of the push button is engaged with the protrusion in the concave portion, and the arc-shaped edge of the hole formed in the push button and the concave portion of the hole are formed. By engaging with the hook, the push button can be easily attached from the front side of the panel with one touch. Also, when the right or left side of the push button is pressed, the push button can drive the rotary switch with the protrusion as a fulcrum.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. 1 to 7, 1 is a front panel of an in-vehicle audio device, 2 is a recess into which a push button is inserted, and a hole 3 is formed in the bottom surface of this recess 2. 4 is a recess 2
Is a push button support plate formed in parallel to the center of the upper and lower surfaces of the inside, and a projection 5 having an arcuate tip is formed at the center of the front edge of the push button support plate 4, and the push button support plate 4 is opposed to each other. A triangular hook 6 is integrally formed on the surface. As shown in FIG. 3, the height of the hook 6 increases from the front side toward the rear side. Reference numeral 7 denotes a push button formed of a translucent material such as polycarbonate or acrylic resin or a non-translucent material, and a support piece 8 extending rearward is formed in parallel on the back surface of the push button 7. Reference numeral 9 denotes a hole formed in the support piece 8, a small groove 10 is formed at the front edge of the hole 9, and a circle centered on the small groove 10 is formed at the rear edge of the hole 9. An arcuate edge is formed. A switch driving piece 11 extends rearward from the rear end of the push button 7, and the switch driving pieces 11 are formed on the left and right sides of the push button 7, respectively. Reference numeral 12 denotes a substrate arranged on the rear portion of the front panel 1, and a switch 13 is fixed to the substrate 12. As shown in FIG. 7, when the push button 7 is inserted into the recess 2 of the front panel 1 from the front side, the support piece 8 of the push button 7 is inserted while contacting the push button support plate 4. When the push button 7 is further inserted, the rear end of the support piece 8 rides over the triangular hook 6, the hook 6 is engaged with the arcuate edge of the hole 9 of the support piece 8, and the small groove 10 of the push button 7 is inserted. On the projection 5 of the push button support plate 4
Engage. In this way, when the push button 7 is moved backward,
It is blocked by the projection 5, and the forward movement of the push button 7 is blocked by the triangular hook 6, and the push button 7 is rotatably supported by the push button support plate 4 with the projection 5 as a fulcrum.

When the right or left side of the front surface of the push button 7 is pressed, the push button 7 rotates about the protrusion 5 as a fulcrum, and the tip of the switch driving piece 11 drives the switch 13. Since the rear edge of the hole 9 of the support piece 8 is formed in an arc shape centered on the protrusion 5, the push button 7
When is rotated, the triangular hook 6 moves along the arcuate hole edge. Although the light guide plate is not shown in FIGS. 1 to 7, the light guide is arranged so as not to prevent the rotational movement of the push button 7 and the push button 7 is illuminated from the rear side as in the conventional example. You may do it.

As described above, the present embodiment can be mounted by inserting the push button 7 from the front side of the front panel 1 without using screws or the like, and has an advantage that the number of assembling steps is small.

Effect of the Invention The present invention has the above-described configuration, and can be easily attached by pushing the push button from the front side of the panel.
