[Industrial applications]

 The present invention relates to a push button device in which a character shape or a design is enlarged, and in particular, a letter or a design provided on the push button is enlarged so that the button can be conveniently pushed even after the product is light, thin and short. , It relates to pushbuttons that are designed to be used correctly so that they are not pressed incorrectly.

[0002]

[Prior art]

 With the development of electronic technology, various electric appliances and communication products, such as wireless telephones, computers, stereos, etc., are put on the market one after another. There are some pushbuttons to control the functions of the. For large-volume electronic products one time ago, the push button provided on it can be made slightly larger in order to make it easier to push with a finger, and as shown in FIG. It has a conductive rubber or a convex point at its lower end, and when it is pressed, it is used to send a signal by making contact with the contact on the circuit board by the conductive rubber or the convex point. It However, as electronic technology progresses further, light, thin, short, small, and multi-functionality will be in the design flow, and in order to reduce the volume of electronic products and make it easy to carry, mini-electronic products such as palm-type mobile phones will be used by each manufacturer. We are developing notebook computers.

[Problems to be solved by the device]

 However, when the volume of the product is reduced, the push button provided on it is also reduced, and the push buttons on the board surface are too close together. You may end up pressing the button, or the displayed characters and designs are too small to be easily identified, and you may use the functions incorrectly. The goal of R & D was to get a product.

[0004]

[Means for Solving the Problems]

 Therefore, the main purpose of the present invention is to provide a push button device in which the letter shape and the design are enlarged. It is made of transparent plastic and has an upper surface with an arc and a lower surface with a flat convex lens. There are letters or designs that allow light to pass through on the plane, and the parts that are not letters or designs are shaded so that when viewed from above, the letters or designs are magnified and identified. It becomes easier and can be easily and accurately pressed.

A second object of the present invention is to provide a push button device in which characters and patterns are enlarged, and a flat portion of the push button facing the arc surface is coated with a colored paint and a colored light-transmitting layer. The rubber body uses liquid rubber containing a special vulcanizing agent to push the rubber body so that it has the property of approaching the button, which causes heating and pressing between the plane of the push button and the rubber body. When done, they are combined together.

【Example】

 As shown in FIG. 1, the push-button device provided by the present invention for expanding the shape and design is mainly used for the numeric keypad of electronic products whose volume is reduced, and even if the arrangement of push buttons is clogged by it. Button pressing is convenient. The structural composition of the present invention includes a push button 1 and a rubber main body 2. The push button 1 is attached to the upper end of the rubber main body 2, and another conductive rubber is attached to the lower end of the rubber main body. Alternatively, the convex point 20 is provided. When the push button is pressed, the conductive rubber or the contact between the convex point 20 and the contact point of the electric circuit board is conductive. The push button 1 is made of a transparent plastic polycarbonate as a convex lens having an arc surface 10 on the upper surface and a flat surface 11 on the lower surface. As shown in FIGS. 3 and 5, light-shielding processing is performed on a portion without a character or a pattern, and when the push button 1 is viewed from above, the character or the pattern is enlarged and it is convenient to press the button. (As shown in FIG. 2).

Further, an outer convex edge 13 is provided around the plane of the push button 1, and an inner convex edge 31 is provided at the peripheral edge of the hole to which the push button 1 is attached. When it is attached to the hole of the shell 3, it can prevent light from leaking from the side of the push button 1 and prevent it from being dug out. In addition, the arc surface 10 formed on the upper surface provides a good touch feeling, and the user can operate it accurately, and it is a practical and pleasant one as a whole, thus increasing the added value. You can

The writing process of the character 12 or the pattern on the plane 11 of the push button 1 is as shown in the figure, and the plane 11 is coated with a light-shielding paint so as to shield the light (different colors are used). It may be applied to a different push button), and with laser engraving technology, remove the required light-shielding paint on the letter 12 or the design so that light does not pass through the letter or the design, or the light is blocked. When applying the color paint, empty the letters or patterns, and then apply a coloring and translucent paint layer on the light-shielding paint layer (different colors may be applied to different push buttons). As a result, when the push button 1 is viewed from the upper side, the character 12 or the pattern on the plane 11 thereof is enlarged and becomes apparent, which makes the push of the button convenient.

Further, in the conventional push button device, a plastic push button and an elastic rubber are combined or attached, but since the properties of the plastic and the rubber are different (the plastic for the process used in general push buttons is melted). The melting temperature is about 120 ° C, and the melting temperature of rubber is about 170-180 ° C). If they are to be bonded and fixed, an adhesive (eg, instant adhesive, bond) is applied between them. Had to be glued together. However, if it is used for a certain period of time, the adhesive will deteriorate and become less sticky, causing the push button to fall off. Therefore, in the method of combining the push button 1 and the rubber main body 2 of the present invention, the melting temperature of the rubber main body 2 is 110 to 120 according to the formulation prepared by adding the vulcanizing agent to the liquid rubber and improving the mixing. It is lowered to a temperature of ℃, and in combination with the characteristics of paint and pigment (pigment) applied to the flat surface 12 of the push button 1, the flat surface 12 of the push button 1 is brought close to the property of the rubber main body 2, As a result, the flat surface 12 of the push button 1 can be bonded onto the rubber main body 2 during manufacture, and can be tightly joined by further heating and pressing, which is an effect that does not fall off permanently in normal use. To be
