DETAILED DESCRIPTION
The disclosure, including the drawings is illustrated by way of example and not by limitation. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.
Referring to FIGS. 1 to 4, an exemplary embodiment of a keyboard 100 includes a keyboard main body 200 and a supporting apparatus 300. The keyboard main body 200 is substantially rectangular. An extending portion 210 is extended from a lower portion of a first sidewall of the keyboard main body 200. Two elongated through holes 220 are defined in the extending portion 210. Two adjusting pins 230 are set on a bottom 250 of the keyboard main body 200, adjacent to a second sidewall of the keyboard main body 200 opposite to the first sidewall, to raise a side of the keyboard main body 200 opposite to the extending portion 210.
A plurality of square first keys is set on a top 240 of the keyboard main body 200 and arranged in a four by five (4×5) matrix. The first row first key is labeled “Caps Lock”. The first row second key is labeled “Q”, “T”, “Esc”, “F7”, “&”, and “7”. The first row third key is labeled “W”, “Y”, “↑”, “F8”, “*”, and “8”. The first row fourth key is labeled “E”, “U”, “PgUp”, “F9”, “(”, and “9”. The first row fifth key is labeled “R”, “I”, “Prtsc”, “Tab”, “Srl”, and “Pause”. The second row first key is labeled “Lower”. The second row second key is labeled “A”, “G”, “←”, “F4”, “$”, and “4”. The second row third key is labeled “S”, “H”, “?”, “F5”, “%”, and “5”. The second row fourth key is labeled “D”, “J”, “→”, “F6”, “^”, and “6”. The second row fifth key is labeled “F”, “K”, “””, “—”, “'”, and “-”. The third row and first column first key is labeled “Upper”. The third row second key is labeled “Z”, “B”, “:”, “F1”, “!”, and “1”. Third row third key is labeled “X”, “N”, “↓”, “F2”, “@”, and “2”. The third row fourth key is labeled “C”, “M”, “PgDn”, “F3”, “#”, and “3”. The third row fifth key is labeled “V”, “L”, “|”, “=”, “\”, and “+”. The fourth row first key is labeled “Backspace”. The fourth row second key is labeled “Ctrl”, “{”, “Ins”, “F10”, “)”, and “0”. The fourth row third key is labeled “Alt”, “}”, “/”, “F11”, “[”, and “]”. The fourth row fourth key is labeled “Win”, “ ̃”, “.”, “F12”, “Del”, and “{grave over ( )}”. The fourth row fifth key is labeled “O”, “P”, “<”, “>”, “,”, and “;”.
Three long second keys are arranged in a line on the keyboard main body 200, between the first keys and the extending portion 210, which are labeled “Space”, “Shift”, and “Enter”, respectively. Arrangement of the first and second keys of the keyboard main body 200 can be changed according to need. In one embodiment, the keys labeled “Caps Lock”, “Shift”, “Upper”, and “Lower” can be made of lighting material. The symbols of each first key of the second to fifth columns of the first to the fourth rows of the keyboard main body 200 are located on a top left corner, a top right corner, a left middle location, a right middle location, a lower left corner, and a lower right corner of each key.
In one embodiment, each key is labeled with six characters or icons each of which are pre-associated with an input and can be selectively input by pressing different key combinations. For example, an upper case located on a top left corner of a corresponding key can be input by pressing the “Caps Lock” key+the key. A lower case corresponding to an upper case of a top left corner of a corresponding key can be input by pressing the key. A upper case located on a top right corner of a corresponding key can be input by pressing the “Caps Lock” key+the “Shift” key+the key. A lower case corresponding to a upper case of a top right corner of a corresponding key can be input by pressing the “Shift” key+the key. A symbol located on a lower left corner of a corresponding key can be input by pressing the “Lower” key+the key. A symbol located on a lower right corner of a corresponding key can be input by pressing the “Lower” key+the “Shift” key+the key. A symbol located on a left middle location of a corresponding key can be input by pressing the “Upper” key+the key. A symbol located on a right middle location of a corresponding key can be input by pressing the “Upper” key+the “Shift” key+the key.
The following depicts how the letters and the symbols of the second key of the first row are input. The letter “Q” is located on a top left corner, the letter “T” is located on a top right corner, the symbol “Esc” is located on a left middle location, the symbol “F7” is located on a right middle location, the symbol “&” is located on a lower left corner, the symbol “7” is located on a lower right corner. The letter “Q” can be input by pressing the “Caps Lock” key+the second key of the first row, the letter “T” can be input by pressing the “Caps Lock” key+the “Shift” key+the second key of the first row, the letter “q” can be input only by pressing the second key of the first row, the letter “t” can be input by pressing the “Shift” key+the second key of the first row, the instruction of the symbol “Esc” can be executed by pressing the “Upper” key+the second key of the first row, the instruction of the symbol “F7” can be executed by pressing the “Upper” key+the “Shift” key+the second key of the first row, the symbol “&” can be input by pressing the “Lower” key+the second key of the first row, the number “7” can be input by pressing the “Lower” key+the “Shift” key+the second key of the first row. Input ways of letters and symbols of the other keys are same as input ways of the letters and symbols of the second key of the first row.
The supporting apparatus 300 is substantially rectangular. An extending portion 320 is extended from an upper portion of a sidewall of the supporting apparatus 300. Two elongated through holes 330 are defined in the extending portion 320, corresponding to the through holes 220 of the extending portion 210 of the keyboard main body 200. A supporting device 38 protrudes up from a top 310 of the supporting apparatus 300, opposite to the extending portion 320, to support a wrist of a keyboard user. A rectangular opening 36 is defined in the supporting apparatus 300, between the through holes 330 and the supporting device 38, for carrying the keyboard 100 conveniently. In one embodiment, the supporting device 38 is made of soft latex, and the shape of the supporting device 38 can be designed according to need.
In assembly, the extending portion 210 of the keyboard main body 200 is placed under the extending portion 320 of the supporting apparatus 300. The through holes 330 of the extending portion 320 align with the corresponding through holes 220 of the extending portion 210. Two screws 400 pass the through holes 330 and 220 respectively, and then are engaged in two screw caps 500, to connect the keyboard main body 200 to the supporting apparatus 300. A distance between the supporting apparatus 300 and the keyboard main body 200 can be adjusted by adjusting location of the screws 400 in the through holes 330 and 220 according to sizes of hands of different keyboard users.
The keyboard 100 reduces the number of the keys by rearrangement keys on the keyboard main body 200, thereby the keyboard 100 can be operated by a single hand. The supporting apparatus 300 can reduce wrist fatigue of the keyboard user, and a distance between the supporting device 38 and the keyboard main body 200 can be adjusted by adjusting location of the screws 400 in the through holes 330 and 220 according to sizes of hands of different keyboard users.
It is to be understood, however, that even though numerous characteristics and advantages of the present disclosure have been set forth in the foregoing description, together with details of the structure and function of the disclosure, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
