Description

Keyboard for touch screen {Key board for touch screen}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a keyboard for a touch screen, and more particularly, to a touch screen keyboard that is attached to an opposite position of a keyboard image displayed on a touch screen of a tablet computer or the like, so that input is convenient and easy.

In general, unlike a personal computer or a notebook computer having a separate keyboard as an input device, a tablet computer inputs by touching a keyboard image appearing on a touch screen without a separate keyboard.

The keyboard image on the touch screen of the tablet computer uses a pressure-sensitive or capacitive technology. In particular, the capacitive touch panel is applied to a small tablet computer or a mobile phone due to its high recognition rate and multi-touch. .

In the keyboard image on the touch screen, an input key button is formed as an image on the touch screen. When the image is touched, a number or a letter corresponding to the key button is input.

However, the biggest drawback of the keyboard image on the touch screen is that the border of the keyboard is not known in the keyboard image, so it is very difficult to input by touching without looking at the keyboard.

In order to solve this problem, an attachable keyboard for a touch screen of a tablet computer has been proposed in Patent No. 10-1128104. However, the screen is attached to a bottom surface of a bottom pad attached to a virtual keyboard displayed on a touch screen of a tablet computer. Problems such as stickiness due to the adhesive layer on the screen after use and deterioration of the adhesive strength after long time use were formed by forming an adhesive layer coated with an adhesive so as to be detachable.

The present invention has been invented to solve the problems of the prior art as described above, the object of the present invention is attached to the screen when in use is convenient to use and there is no stickiness due to adhesives, etc. after use, even after long use It is to provide a keyboard for a touch screen that does not degrade.

In the keyboard for a touch screen according to the present invention, a keyboard having a plurality of pressing portions formed in a base portion so as to be attached to correspond to a keyboard image formed on a touch screen of a tablet computer, the air passage so that air is discharged between the base portions of the pressing portions. Is formed, the upper side of the base portion is characterized in that the adsorption portion is provided so as to be fixed to the touch screen surface.

The present invention is very convenient to use because the adsorption portion for fixing to the touch screen is formed on the upper side of the keyboard and does not move when in use, the air passage is formed in each pressing portion is excellent in the touch feeling by the smooth operation of pressing. , The transparent portion is formed in the pressing portion and the printed strip is formed to have an effect of improving visibility.

1 is an exploded perspective view showing a keyboard for a touch screen according to the present invention;
2 is a plan view of a keyboard for a touch screen according to the present invention;
3 is a bottom perspective view of a keyboard for a touch screen according to the present invention;
4 is a cross-sectional view taken along the line II in FIG.
5 is a cross-sectional view taken along the line II-II in FIG.
FIG. 6 is a cross-sectional view taken along the line III-III of FIG. 2.

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

1 is an exploded perspective view illustrating a keyboard for a touch screen according to the present invention, and FIG. 2 is a plan view of the keyboard for a touch screen according to the present invention, and the keyboard image 12 displayed on the touch screen 11 of the tablet computer 10 is shown. The keyboard 20 is attached to the upper side of the).

The keyboard 20 is formed of a silicon material, and the pressing portion 22 protrudes upward from the base portion 21 positioned on the surface of the touch screen 11 to correspond to the keyboard image 12.

And each press part 22 is formed with an air passage 23 so as to discharge the air as shown in FIG.

The air passage 23 is formed between the pressing portions 22 as well as on both edges of the pressing portions 22 and the base portion 21 of both edges so that the air therein is discharged when the pressing portion 22 is operated. By doing so, you can get a better touch.

In addition, the printing strip 24 is formed on the side surface of each pressing portion 22 so that the visibility is good, it is most preferable that the printing strip 24 is formed in blue or green.

The printing strip 24 may be printed on not only the side surface of each pressing portion 22 but also the upper surface, that is, the edge of the transparent portion 22a.

The upper portion of each pressing portion 22 is formed as a transparent portion 22a so that the letters of the keyboard of the keyboard image 12 appearing on the touch screen 11 can be easily recognized.

On the other hand, the adsorption part 25 which is adsorbed by the touch screen 11 is formed on both upper sides of the base portion 21.

The adsorption part 25 is formed in a dome shape and the internal air is discharged as the upper part is pressed, and the negative pressure acts on the surface of the touch screen 11 so as to be fixed.

The thickness of the transparent part 22a of the pressing part 22 is formed to be thinner than the thickness of the base part 21, and is preferably about 1/2 to 1/3 of the base part 21.

In addition, the thickness of the adsorption part 25 is formed to be smaller than the thickness of the base part 21. Preferably, the adsorption part 25 is formed of 1/5 to 1/10 of the base part 21 so as to have an elastic force and return to its original state. Most preferred.

In one embodiment of the present invention, the material of the keyboard 20 is formed of silicon, more preferably by adding 0.1 to 1% by weight of platinum to 100% by weight of silicon to improve the transparency.

In another embodiment of the present invention, when 0.1-1% by weight of silver nanomaterial and 0.1-1% by weight of fragrance are added to 100% by weight of silicone of the keyboard, the fragrance is discharged from the product together with the antibacterial effect.

The raw materials blended as described above are molded in a mold of 160 to 170 ° C., and after removing foreign substances adhering to the outside, they are heated at 120 ° C. in a dryer for 2 hours or 2 in boiling water to remove the smell of silicon. It is completed by immersing for more than hours.

The touch screen keyboard according to the present invention configured as described above allows the keyboard image 12 to appear on the touch screen 11 when an input operation is performed on the tablet computer 10, and then the keyboard ( 20) will be attached.

That is, by placing the keyboard 20 on the upper side of the keyboard image 12 to match the keyboard 22 of the keyboard image 12 with the pressing part 22 of the keyboard 20, the suction part 25 formed on the upper side is illustrated in FIG. 5. As shown in FIG. 3, when the finger is pressed, air is discharged from the inside and negative pressure acts on the inside of the suction unit 25 to be fixed to the surface of the touch screen 11 at the edge of the suction unit 25.

At this time, when the user presses the pressing part 22, the air is discharged to the air passage 23 formed in the base part 21, so that the pressing part 22 is pressed to a predetermined height to make an input.

In addition, the upper surface of the pressing portion 22 is formed of a transparent portion 22a and a printing strip 24 is formed at the edge thereof, so that the visibility is improved, thereby making input work easier and more convenient.

In addition, since the keyboard 20 is located in the touch screen 11, not only the appearance is neat but also the fixed state is maintained by the adsorption unit 25, thereby reducing the occurrence of a typo due to flow or the like during the input operation.
