Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a push button device used in intercoms, telephones, home security, etc.

BACKGROUND TECHNOLOGY In general, a push button device used for home security etc. has a push button 2 integrally formed in a case 1 as shown in FIGS. 4 and 5, and when the push button 2 is pressed, The device is configured to press a switch 4 mounted on a printed circuit board 3 or the like. Further, on the surface of the case 1, a transparent or translucent sheet 6 having a through hole 5 for exposing the push button 2 and display characters to display the function of the push button 2 inserted into the through hole 5 is attached. Furthermore, a lamp 7 is attached to the printed circuit board 3 to indicate the operation of the push button 2, and the blinking of the lamp 7 is visible through the sheet 6.

Problems to be Solved by the Invention However, with this type of device, if you want to change the function display of each push button 2, it is necessary to replace the entire sheet 6, and even if you want to make some push buttons 2 inoperable, it is necessary to replace the entire sheet 6. It is necessary to replace the sheet 6 with a different sheet 6 from which the through holes 5 at the positions corresponding to the push buttons 2 have been removed, and especially for home security systems where there are several push buttons 2 and some of them are made inoperable or operable. This was not very desirable as a push button device such as Ulytee.

The present invention eliminates the above-mentioned drawbacks of the conventional technology, and aims to provide an excellent push button device that has a simple configuration and can easily display and switch between operable and inoperable states. .

Means for Solving the Problems In order to achieve the above object, the present invention attaches a transparent or semi-transparent cover to each push button in a removable manner, and a function display sheet placed on the surface of each push button is passed through the cover to the outside. The push button is configured to be more transparent, and a separate cover with a stopper different from the cover is prepared, and by attaching the cover to the push button, the push button becomes inoperable.

Therefore, according to the present invention, if you want to make some push buttons inoperable, you can simply fit a cover with a stopper to the push buttons, and there is no need to convert a large sheet separately. This has the advantage that the display can also be easily changed.

Embodiment FIGS. 1 to 3 show the configuration of an embodiment of the push button device of the present invention. 1 to 3, 11 is a case configuring a telephone, home security, or other equipment, 12 is a recess formed in the case 11 for a push button device, and 13 is a through hole 12 on the side of the recess 12. A bearing recess 14 for a push button pivot is formed integrally with the push button, and a push button 14 has a shaft 15 formed at one end inserted into the bearing recess 13 so as to be rotatable about the shaft 15. , 16
Reference numeral 17 indicates a projection for attaching a cover integrally formed on the side surface of the push button 14, 17 indicates a rib for preventing slipping off, integrally formed on the other end of the push button 14, and 18 indicates an operation display formed on the upper surface of the push button 14. through hole, 19 is push button 14
A function display sheet placed on the top surface of the sheet and having a through hole 27 in a position opposite to the through hole 18;
0 is a cover that is removably fitted and fixed to the push button 14; 21 is formed on the inner surface of the cover;
An engagement recess 22 that engages with a cover attachment protrusion 16 formed on the side surface of the case 1 is a screw 2 inside the case 1.
Printed circuit board fixed by 3 etc., 24
A switch 26 is attached to the printed circuit board 22 and is pressed by a pressing portion 25 integrally formed on the lower surface of the push button 14 when the push button 14 is pressed.
28 is a diamond cut portion formed on the inner surface of the cover 20 facing the through hole 27, and 29 is a through hole 30 in the center. The cover 20 is a panel mounted on the upper surface of the case 11 so that the cover 20 protrudes from the through hole 30.

In the embodiment described above, the push button 14 has a shaft portion 15 formed at one end thereof inserted into a bearing recess 3 formed in the case 11, and is mounted rotatably around the shaft portion 15. Therefore, by pressing the cover 20 and rotating the push button 15, the pressing portion 25 presses the switch 24, and the switch 24 can be operated. A rib 17 is integrally formed on the other end of the push button 14, and is inserted into a through hole formed in the side surface of the push button mounting recess 12, so that the push button 14 will not come out upward due to vibration or the like. .

On the other hand, since the cover 20 is made of a transparent or translucent synthetic resin material and is attached to the push button 14 via the function display sheet 19, the function of the push button 14 can be displayed on the function display sheet 19. You can see through it easily. The function display sheet 19 has a through hole 1 formed in the push button 14.
Since the through holes 27 are formed opposite to the through holes 18 and 8, the blinking of the lamp 26 can be easily confirmed through these through holes 18 and 27. Also, cover 20
is removably attached to the push button 14 by engagement between the attachment protrusion 16 and the engagement recess 21. Therefore, the function display sheet 19 or the cover 20 itself cannot be replaced. It is also extremely easy to make the push button 14 inoperable.

That is, if you want to make the push button 14 inoperable and remove the display of the push button 14, first, as shown on the right side of FIG. A sheet 19' without holes 27 is used. In this state, in place of the normal cover 20, a cover 20' having a stopper 30 below the side plate is detachably attached to the push button 14 in the same manner as the normal cover 20. In this way, the stopper 30 comes into contact with the bottom surface of the push button mounting recess 12 in a normal state, and even if the cover 20' is pressed, the push button 14 will not rotate downward, and the switch 24 will naturally not be activated.
Therefore, this makes it possible to make the push button 14 completely inoperable and also to have no display thereof.

In this way, according to the above embodiment, the display sheet 19' having no function display or through holes 27,
A cover 2 having a stopper 30 that comes into contact with the bottom surface of the push button mounting recess 12 when normally mounted on the side plate.
Prepare 0' and press button 1 as needed.
4, the push button 14 can be easily made inoperable and without display, and there is no need to replace various large sheets separately provided as in the past, and any push button can be easily made inoperable. It has the advantage of being able to

In the embodiment, the covers 20 and 20' are both transparent or semi-transparent, but the cover 20' can also be made opaque. In this case, function display sheet 1 with no separate display
There is no need to prepare 9'.

Effects of the Invention As is clear from the above embodiment, the present invention provides a removable transparent or translucent cover attached to the push button via a function display sheet, and by pressing the cover, the push button can be pressed. In addition to using a cover that can no longer be pressed even in a normal attached state, this cover is configured to be removably attached to the push button in place of the cover. According to the present invention, there is an advantage that by replacing each of the covers, the push button to which the cover is attached can be easily switched from being inoperable to being operable.
