Description

[Detailed Description of the Invention] The present invention relates to a push button device that can be suitably applied to push button switches of various electric or electronic devices.

By the way, in this type of conventional device, as shown in FIG. 1, a button body 2 having a long press pin 3 protruding from the back surface for pressing the switch means S is attached to the back surface of a panel 1 of the device. While the button body 2 is slidably fitted into the holder 4, the button body 2 is always held in the non-operating position direction (arrow A) by a spring 5 wound around a press pin 3.
direction), and the stopper 6 prevents the holder 4 from escaping from the holder 4 due to this auxiliary force.

Therefore, this conventional device has the drawbacks of an extremely large number of parts, resulting in high costs and a large number of assembly steps.

The present invention was devised in view of the shortcomings of the conventional device, and by integrating a spring effect part that biases the button body toward the non-operating position and a pressing part etc. in the holder itself, parts can be reduced as much as possible. While the push button device has a small number of points, the push button device is intended to be able to control two non-operable members, namely, switch means.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 is a side sectional view of the push button device according to the present invention;
As is clear from this figure, the device can be roughly divided into two members: a button body 11 and a holder 12.

As is clear from FIGS. 3 and 4, one button body 11 is made of a rectangular parallelepiped made of metal or synthetic resin with an opening on the back surface to make it hollow, and the left and right edges of both ends of this back surface are Two engaging pieces 13
It is constructed by providing a pivot projection 14 on the mid-abdominal part, and furthermore, the back surfaces 15a and 15b of the upper and lower edges of the above-mentioned both ends are used as pressing surfaces, and the above-mentioned engaging pieces 13 are respectively provided on the outer surface side. engaging claw 13a
has been established.

The holder 12 is made of a synthetic resin molded product, and has a rectangular shape with a mounting rib 16' for mounting on the periphery of the mounting hole P1 of the support panel P, as is clear from FIGS. 5 and 6. A holder main body part 16 consisting of a frame body, and this holder main body part 16
A support bar 17 is provided across the left and right edges of the central portion on the back side of the holder, a fulcrum part 18 is formed by protruding the support bar 17 on the front side, and a support bar 18 extends from the upper and lower edges of the support bar 17. and an operating protrusion 2 on the back side of each end.
1 and 22, respectively.

Note that the support beams 17 of the elastic support portions 19 and 20
The root portions 19', 20' of the elastic support part 1 are thinned, and the elastic support part 1 is supported by the root portions 19', 20'
9 and 20 can be easily bent. Of course, it is not necessary to make only the root portion thin, and the entire elastic support portion may be made thin.

The button body 11 and the holder 12 are each configured as described above, and the button body 11 configured in this way is prevented from falling off by engaging the engaging claw 13a with the edge of the back surface of the holder body portion 16. By being slidably fitted into the holder main body part 16, it becomes integral with the holder 12, and in this state, the elastic support parts 19, 20 are pressed at both ends via the pressing surfaces 15a, 15b. By being pushed in the direction of detachment from the holder body 16, all the engaging claws 13a are held in the non-operating position where they are engaged with the edge of the back surface of the holder body 16, and the pivot projection 14 is brought into contact with the fulcrum 18. I'm letting you do it.

Since the present invention is constructed as described above, when the upper or lower end of the button body 11 is pressed, the button body 11 uses the pivot 18 as a fulcrum and follows the direction in which it is pressed. Rotate.

For example, if the upper end of the button body 11 in the non-operating position is pressed, the pressing force will be
As a result, the button body 11 overcomes the elasticity of the elastic support part 19 and rotates clockwise in the figure about the pivot part 18 as a fulcrum, and the elastic support part 19 is rotated clockwise in the figure. The base portion 19' is rotated in the same direction as a fulcrum, and the operating protrusion 21 is used to turn on or off a switch means (not shown).

Next, when the pressing force is released, the button body 11 is rotated counterclockwise by the restoring force of the elastic support portion 19 and returns to its original non-operating position.

Since the present invention is constructed as described above, the push button device can be constructed simply from two parts, the button body and the holder, which reduces the cost and facilitates assembly.

Moreover, in the present invention, the button body can be rotated within the holder using the midsection as a fulcrum, so it is an excellent invention that allows one push button device to control two operated members.
