This application is a broadening reissue application of U.S. application Ser. No. 15/788,839, issued as U.S. Pat. No. 10,115,538 B2 on Oct. 30, 2018, which is incorporated by reference into the present application.
The present invention relates to light-pervious bicolor key cap, especially to a light-pervious bicolor key cap having a cap cover with a material filling protrusion at a lateral side and a convex piece at an inner side, and a letter or a punctuation in a continuous status is formed on the cap cover.
Quite a few of tools or means for inputting data are provided in the prior art, and there is no doubt that a keyboard, for example used in a computer, is mostly adopted, thus the keyboard is a must have equipment among the hardware for assembling a computer, the reason is that consumers have already gotten used to the conventional typing operation.
The key switches in a keyboard can be categorized into a mechanical type and a membrane type; for satisfying the trend of being lighter, thinner, shorter and smaller, the membrane type and an electric-conductive rubber are mostly adopted for gradually replacing the mechanical type. The principle of the membrane type is that: a material filing protrusion formed in the electric-conductive rubber is pressed for being in contact with a connecting joint formed on a printed membrane circuit disposed below for achieving an objective of inputting a command.
Referring to
Accordingly, a novel light-pervious bicolor key cap for overcoming the above-mentioned disadvantages shall be provided.
One primary objective of the present invention is to provide a light-pervious bicolor key cap, which includes a key frame having a first color and formed with a plurality of thin ribs , and the front ends of the plural thin ribs are formed with at least one letter or one punctuation in a continuous status, a plastic having a second color is provided through being filled from a filling hole at a lateral side of a second mold, so that the letter or the punctuation can be formed on a surface of a cap cover having the second color.
Another objective of the present invention is to provide a light-pervious bicolor key cap, wherein a letter or a punctuation is not formed with any notch, thereby allowing the letter or the punctuation to be provided with a better appearance when the light is permeating through.
For achieving said objectives, the present invention provides a light-pervious bicolor key cap, which includes: a key frame, having a first color and formed with a plurality of thin ribs, wherein front ends of the plural thin ribs are formed with at least one letter or one punctuation, and the letter or the punctuation is formed in a continuous status without any notch; and a cap cover, having a second color, wherein the letter or the punctuation is formed on a surface of the cap cover so as to form a bicolor key cap, an outer side of the cap cover is formed with a material filling protrusion allowing a plastic having the second color to be filled in, and an inner surface of the cap cover is formed with at least one convex piece located below the letter or the punctuation, and the plastic having the second color is allowed to pass two sides defined at the bottom end of the convex piece having the first color for enabling the convex piece having the second color to be formed, and the convex piece having the second color is not fixedly combined with the key frame in a fused or molten fashion; so that through removing the convex piece having the second color, the letter or the punctuation of the cap cover is prevented from being formed with any notch and capable of allowing the light to fully permeate.
For fully disclosing the structure, the characteristic and the objective of the present invention, one preferred embodiment with reference to figures is provided hereinafter for detailed illustration.
Referring from
As shown in figures, according to one preferred embodiment of the present invention, the light-pervious bicolor key cap includes a key frame 10, a cap cover 20 and a cap column 30.
The key frame 10 is provided with a first color and formed with a plurality of thin ribs 11, and the front ends of the plural thin ribs 11 are formed with at least one letter or one punctuation 12, and the letter or the punctuation 12 is formed in a continuous status without any notch. Wherein, the first color is a light-pervious color for example but not limited to red, pink, green or blue, the amount of the plural thin ribs 11 is for example but not limited to three, and the letter or the punctuation 12 is in the continuous status, so that the letter or the punctuation 12 can be prevented from being formed with any notch or opening after being molded with an injecting means.
The cap cover 20 is provided with a second color, the letter or the punctuation 12 is formed on a surface of the cap cover 20, thereby forming a bicolor key cap. Wherein, the second color is for example but not limited to black or white, and an outer surface of the cap cover 20 is formed with a material filing protrusion 21 for allowing a plastic having the second color to be filled, and an inner surface of the cap cover 20 is formed with at least one convex piece 22 located below the letter or the punctuation 12, the plastic having the second color is allowed to pass two sides defined at the bottom end of the convex piece 22 for enabling the convex piece 22 having the second color to be formed, and the convex piece 22 having the second color is not fixedly combined with the key frame 10 in a fused or molten fashion; if the convex piece 22 is not removed, a light source would be blocked by the convex piece 22 and at least one notch could be formed on the letter or the punctuation 12. As such, through removing the convex piece 22 having the second color, the letter or the punctuation 12 of the cap cover 20 is prevented from being formed with any notch and capable of allowing the light to fully permeate.
