Abstract

PURPOSE:To facilitate the exchange of buttons and prevent the buttons from abnormal external forces and intrusion of dust by forming integrally a plurality of buttons of silicon system rubber to be held and sandwiched between a base bed and a panel. CONSTITUTION:A plurality of buttons 11 formed of silicon system rubber on a button plate 10 held and sandwiched between a base bed 1 and a panel 13 are located and attached to annular projections 7 on an operating surface 2 and an operating shaft 11c of the button 11 is guide inserted into a guide hole 8. Also an annular upright wall 12 of button plate 10 is inserted in an annular groove 13A provided in the same position of a panel 13. When the button 11 is depressed, the operating shaft 11c transformed and compressed in the thin wall portion 11A descends to depress a switch 4. When the button 11 is further depressed, the thick wall portion 11B is pressed against the annular projection 7 to prevent the operating shaft 11c from abnormal descent and the switch 4 and controlling parts 3 from breakage and damage. Also, since the annular upright wall 12 is inserted in the annular groove 13A of the panel 13, dust does not intrude into the interior through a through hole 14 in the panel 13 from the button 11 portion to provide secure fixed attachment of the button to the button plate.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a button mounting structure for a push button portion having a relatively large button with good operability and a beautiful appearance.

[Conventional technology]

In conventional button operations, the buttons are attached almost integrally with the operation control body, as shown in Japanese Utility Model Publication No. 57-58398, or the buttons are installed separately on the operation body, so it is not easy to replace the buttons. It was there.

In addition, switches placed in relatively low places, such as those on electric fans, are often pressed with feet or are difficult to handle, and the operating force is greater than expected. It is essential.

[Problem that the invention seeks to solve]

In the above-described conventional method, operation buttons are individually installed, and the buttons are also relatively small and made of a hard material, and are not very good in terms of installation time, operability, and feel. In addition, dust easily entered through the narrow opening, and there was a high risk of poor contact.

The purpose of the present invention is to increase the size of the button by using an elastic material to obtain a soft-touch action with good operability, and to make it easy to assemble or replace as desired. Fixed support using the inch method. In addition, the shape is such that it is difficult for dust to enter, the button plate is prevented from being pulled out, and the configuration is suitable for the actual use so that no more than necessary operating force is applied to the control section.

[Means for solving problems]

The above purpose is to facilitate the replacement of the buttons by integrally forming the buttons using an elastic material, especially silicone rubber, and supporting them between the base and the panel, and to prevent abnormal external forces in this state. Can prevent dust from entering.

[Effect]

The button has a thick wall that is positioned and supported by the panel.

The thin wall part forms the operating shaft, and the connection with the base prevents damage due to abnormal pushing force when changing the switch of control parts6.
Naturally, the buttons can be easily replaced, and a button structure with good operability and good appearance can be obtained.

〔Example〕

An embodiment of the present invention will be described below based on the drawings.

Reference numeral 1 denotes a base made of synthetic resin, and has an operation surface 2 on its upper surface. Reference numeral 3 denotes a control component equipped with a plurality of switches 4, light emitting diodes 5, etc., and is fastened into the base 1 with a plurality of screws 6.

Reference numeral 7 denotes a plurality of annular protrusions installed in the operation surface 2 of the base 1 at positions equivalent to the arrangement of the switches 4 of the control component 3, and a guide hole 8 having an annular wall is provided in the center.

9 is a through hole for the light emitting diode 5 of the control component 3. ]
0 is a button plate having a plurality of buttons 11 arranged in the same manner as described above, and is integrally made of an elastic body made of silicone rubber. The button 11 is approximately bowl-shaped and has a thin wall portion 11.
A, the thick wall portion 11B and the operating shaft 11C are erected from the thick wall portion. Reference numeral 12 denotes an annular vertical wall provided around the entire outer circumference of the button plate 10. 13 is a panel located on the operation surface of the base 1. 1
4 is a through hole for the button 11, and 15 is a display hole for a light emitting diode. A plurality of screws 16 fasten the panel 13 to the operation surface 2. Numeral 17 is a bottom opening that covers the lower opening of the base 1, and is fastened to the base 1 with screws 19 via a plurality of supports 18.

In the above configuration, after fastening the control component 4 to the base 1 with the screws 6, the button plate 10 is positioned on the operation surface 2, and the panel 1
3 is fastened to the base 1 via the button plate 10 with screws 16. The assembled state of the button 11 will be explained with reference to FIG. Button 11
is mounted with the annular protrusion 7 as its approximate position, and the button 11
The second operating shaft 11G is guided and inserted through the guide hole 8. Further, the annular standing wall 12 of the button plate 10 is inserted into an annular groove 13A provided at the same position in the panel 13. At this time, when the button 11 is pressed, the thin wall portion 11A is deformed and compressed, and the operating shaft 11G is lowered to press the switch 4. When pressed further, the thick portion 11B comes into pressure contact with the annular protrusion 7 to prevent the operating shaft 11C from descending abnormally, and the switch 4. This is to prevent breakage and damage to the control parts 3. Also, since the annular standing wall 12 is inserted into the annular groove 13A of the panel 13, the through hole 1 of the panel 13 is inserted from the button 11 part.
This prevents dust from entering the inside through the button plate 4, and prevents the button plate 11 from being pulled out by force, thereby ensuring a securely fixed state.

〔Effect of the invention〕

According to the present invention, it is possible to obtain a button that is easy to assemble, has good operability, and has a high sensitivity, and also provides a reliable button structure that is beautiful in appearance.
