Abstract

The utility model relates to a single-hand operated keyboard, belonging to the keyboard technical field, which comprises a single-hand input area where a plurality of keycaps are distributed in multilayer structure; wherein, the keycaps in each layer are arranged into oblique lines or curved lines which are different in shapes to conform with different user habits and hand shapes; thanks to limited hand movement distance under single hand operation, the keycaps are made into small size to reduce keyboard area.

Description

Single-hand operated keyboard

Technical field:

The utility model relates to keyboard technique field, particularly single-hand operated keyboard.

Background technology:

The arrangement of the literal of electronic digital products such as now all desk-top computers and notebook computer, learning machine, palm PC, smart mobile phone and numeral input or other feature operation keycap nearly all is that orthogonal straight lines is arranged, and is with the hands to import or a finger input.Along with the microminiaturization of computing machine, particularly notebook computer, little during to ten inches and following size, with the hands come operation keyboard just not have enough spaces.Even want to do the small screen, because of as all kinds of reasons such as keyboard arrangement are unreasonable, notebook can't be accomplished desirable miniature dimensions.The little keycap by the orthogonal straight lines arrangement mode of small-sized digital product such as learning machine is actually with forefinger operation literal and numeral input, and input speed is slow, with the same all efficient not high enough problem of 9 key thumbs input of mobile phone.Keyboard is as the indispensable parts of computing machine and notebook computer and other digital products, when other accessories can develop into enough little the time, the arrangement mode that keyboard changes keycap with regard to needs and adjusts keycap realizes that function and input efficiency do not subtract and area is littler, well select is that both hands input and a finger input are become singlehanded input, to adapt to the demand of market and development in science and technology, so people wish to have a kind of keyboard that can be applicable to one-handed performance.

The utility model content:

The purpose of this utility model is the single-hand operated keyboard that provides a kind of suitable one-handed performance at the deficiencies in the prior art, can reduce keyboard area.

For achieving the above object, the utility model adopts following technical scheme:

Single-hand operated keyboard includes singlehanded input field, and singlehanded input field is provided with a plurality of keycaps that distribute by sandwich construction, and the keycap of each layer is according to angled straight lines or curved arrangement.

Described angled straight lines and X-axis form included angle A, and the value of included angle A is greater than 0 ° and less than 90 °, or greater than 90 ° and less than 180 °.

Described curve is a circular arc line, and the center of circle of each layer circular arc line is on same straight line, and the arc radius ecto-entad successively successively decreases.

Described circular arc line forms included angle B in the tangent line and the Y-axis of midpoint, and the value of included angle B is 0 ° to 180 °.

Spacing between the adjacent keycap is not more than 6mm.

The keycap of adjacent two layers aligns mutually and arranges or the dislocation arrangement.

Described singlehanded input field also is provided with the thumb input field that is suitable for the thumb input, and the thumb input field includes thumb district keycap.

The utility model beneficial effect is: the utility model includes singlehanded input field, singlehanded input field is provided with a plurality of keycaps that distribute by sandwich construction, the keycap of each layer is according to angled straight lines or curved arrangement, this angled straight lines or curve are according to the shape of operator's custom and hand and different, be applicable to one-handed performance, the displacement of finger tip between keycap is little during one-handed performance, and keycap can be done lessly, reduces keyboard area.

Description of drawings:

Accompanying drawing 1 is a structural representation of the present utility model

Accompanying drawing 2 is structural representations of the utility model embodiment 2

Accompanying drawing 3 is structural representations of the utility model embodiment 3

Embodiment:

Below in conjunction with accompanying drawing the utility model is further described, see accompanying drawing 1, single-hand operated keyboard, include singlehanded input field, singlehanded input field is provided with a plurality of keycaps 1 that distribute by sandwich construction, the keycap 1 of each layer is arranged according to angled straight lines, and the keycap 1 of singlehanded input field includes at least one half letter key, also can increase numerical key and function key.Spacing between the adjacent keycap 1 is not more than 6mm, and keycap 1 mutual dislocation of adjacent two layers is arranged.

Angled straight lines and X-axis form included angle A, X-axis at single-hand operated keyboard in a lateral direction, the value of included angle A is greater than 0 ° and less than 90 °, or greater than 90 ° and less than 180 °, A is fit to right-hand operated during less than 90 °, A is fit to left-handed operation during greater than 90 °.Keyboard forms the room in the inboard by angled straight lines, provides the space for touch pad is set.

Embodiment 2, see accompanying drawing 2, present embodiment as different from Example 1 the keycap 1 of each layer according to curved arrangement, curve is a circular arc line, the center of circle of each layer circular arc line is on same straight line, and the arc radius ecto-entad successively successively decreases the keycap 1 alignment arrangement mutually of adjacent two layers.Circular arc line forms included angle B in the tangent line and the Y-axis of midpoint, Y-axis is on the longitudinal direction of single-hand operated keyboard, and the value of included angle B is 0 ° to 180 °, and B is fit to right-hand operated during less than 90 °, B is fit to left-handed operation during greater than 90 °, both has been fit to left-handed operation when B equals 90 ° and also has been fit to right-hand operated.Other structure is identical with embodiment 1 with principle, no longer repeats here.

Embodiment 3, see accompanying drawing 3, the singlehanded as different from Example 1 input field of present embodiment also is provided with the thumb input field that is suitable for the thumb input, the thumb input field includes thumb district keycap 2, thumb district keycap 2 can be by straight line or curved arrangement, and in the present embodiment, keycap 1 some by line spread, another part is by curved arrangement.Other structure is identical with embodiment 1 with principle, no longer repeats here.

Angled straight lines or curve are applicable to one-handed performance according to the shape of operator's custom and hand and different.When people are using keyboard particularly miniature keyboard are carrying out one-handed performance, at health behind keyboard, hand just is difficult to directly be placed on keyboard to be operated, and can become certain angle of inclination to place, operate and have some setbacks, and keycap 1 of the present utility model is according to angled straight lines with angle of inclination or curved arrangement, makes that go smoothly can normal running under situation about not straightening.Finger tip is little in the displacement of 1 of keycap during one-handed performance, and keycap 1 can be done lessly, and keyboard size is also just smaller, has effectively utilized the space.Keycap quantity, each key function and application software are consistent with common keyboard, are used easily.The utility model can be used as the input block of computer, also can be used as the literal input block of other digital equipment.
