CN2722322Y - Right tilted keyboard of left-hand operating key - Google Patents

Abstract

The utility model relates to a right tilted keyboard with a left-hand operating key. The arrangement of the left-hand operating keys is changed to tilt right, but the angle is the same as the of the traditional keyboard, and the right-hand operating keys don't change. The utility model solves the problem that the operation is inaccurate, and the left wrist joint is fatigable after abduction when the left hand operates the keyboard. In order to adapt to the new keyboard layout, the clear area formed at the center is reset, and at the same time the original ' key moves to the right side of the 'Tab' key, '/'key moves to the right side of the 'CapsLock' key, the '\' key moves to the top end of the trigonal area at the center and the constantly used '<-Backspace key moves to the lower part of the trigonal area. The '-' key and the '='key of the number key move right horizontally at two key mappings, and the '[' key and the ']' key move to the left end of the digital keyboard. If adopting the parallelogram key, the appearance surface is visual and the operation is more accurate.

Description

Left-handed operation key Right deviation formula keyboard

Technical field the utility model relates to a kind of peripherals of computing machine, is specifically related to a kind of improvement of computer keyboard symbol layout.

The computer keyboard standard character keypad right-hand man that background technology is traditional operates strong vergence direction unanimity of arranging, and is to be tilted to the left.The right hand and wrist joint are unfolded naturally during operation, and right arm is to-and-fro movement.And left hand and wrist joint are the abduction state, and left arm is swing.So just cause left wrist joint fatiguability, pin down tendon, hinder blood circulation, hinder nerve tract, problem such as left-handed operation is inaccurate.In order to address the above problem, make keyboard in use meet ergonomics, people have invented division formula keyboard, as the natural keyboard of Microsoft release.This keyboard makes the division of right-hand man's operating key, and each line unit all is " V " font to be arranged, and the finger itself that it has ignored the people is in design just shortened naturally by middle sensing little finger, and both hands are made the button shape and are placed on naturally on the desktop, and itself is arranged in a linear finger tip.And division formula keyboard left-handed operation key has strengthened the swing of outer commentaries on classics of left wrist and left forearm still for being tilted to the left, so do not address the above problem.And this keyboard and conventional keyboard difference are bigger." A " font keyboard of releasing in 2003 is as the KBS-6 keyboard of round trip flight swallow.Adopted flat shape quadrilateral keycap, the angle of inclination of flat shape quadrilateral keycap is consistent with every row key symbol angle of inclination, and right-hand operated key keycap is tilted to the left, and left-handed operation key keycap is tilted to the right.But the physical location of key symbol does not change, and does not address the above problem at all yet.

The summary of the invention the purpose of this utility model will solve left finesse joint abduction, left little arm swing, problems such as the fatigue that causes, discomfort exactly.

The purpose of this utility model is achieved in that conventional keyboard standard character keypad right-hand operated part constant, the vergence direction of every row key of left-hand part is changed into be tilted to the right, and the angle of inclination is identical with former angle.Right-hand man's operating key is arranged as symmetry status like this.In order to adapt to keyboard layout, the triangle stepped appearance blank to the center occurs adds key and is replenished, and the name of key symbol has been called corresponding variation.The shared total area of standard character keypad is not changed.

The utility model makes the left finesse joint obtain nature to unfold like this, during use about palm, arm all keep straight line, thereby can not produce the sense of aching.The palm moving direction is identical with the arm moving direction, and button is accurate.And similar to the conventional keyboard fingering, adapt to easily.As adopt the parallelogram keycap, and appearance is directly perceived, and it is more accurate to operate.

Specific embodiments key symbol position is finished after the adjustment as shown in Figure 1, and standard character keypad right-hand operated district has lacked five keys, and the left-handed operation district is many four keys middlely a triangle stepped appearance blank occurs.With the original right-hand operated of standard character keypad district " ' " key moves to " Tab " key right side; "/" key is moved to " CapsLock " key right side; Will " " key moves to top, central cam clear area, and the " ← Backspace " key that often uses is moved to descending same position.With the numerical key of standard character keypad and "-" key "=" key to two key positions of right translation; " [" key, "] " key is moved to the left end of numerical key, and the operation fingering of letter key and numerical key does not change like this, and just a few symbols key changes.Make this keyboard adapt to use easily.

Triangle key that stepped blank top the adds conduct that the center occurs " " key, the below adds any key as shown in Figure 2 by User Defined, also can make cursor movement key as shown in Figure 1.So not only convenient the use, and the right side cursor movement key can be cancelled.With former cursor movement key position be made as handwriting pad or as shown in Figure 4 with editing area key by three row and be two row, reduce keyboard length.Can also be as shown in Figure 3 change the angle of inclination of every row key symbol into 26.57 degree by traditional angle of inclination, the central space place can add six standard keys like this, can also can be by User Defined for cursor movement key; The space bar left side is 4 standard keys, and a key that has more than conventional keyboard can be 3 keys as conventional keyboard also by User Defined.

Right-hand man's operating key is made the parallelogram keycap as shown in Figure 5, and the angle of inclination of keycap, direction are identical with arrangement angle, the direction of every row key symbol." 5 " key, " 6 " key, " ← Backspace " key, "=" key, " Enter " key, " Shift " key, " Ctrl " key, " ` " key, " Tab " key, " Caps Lock " key change right-angled trapezium into, " " key and cursor movement key district change isosceles trapezoid into.Do arc groove on each keycap, its vergence direction and key symbol vergence direction one to.Like this, the finger button is accurate when touch system, can facilitate good fingering custom.Also can be as shown in Figure 6 with " ← Backspace " key, "=" key key symbol name swap, "=" key becomes the flat shape quadrilateral of standard keycap, saves the space and merges with " ← Backspace " key; " Shift " key becomes the flat shape quadrilateral of standard keycap, saves the space and merges with " Enter " key, so that " ← Backspace " key and " Enter " key area increase, are convenient to operation.

As long as key symbol title is identical, the signal that sends during button is just identical with conventional keyboard for the utility model, and the driver that the utility model need not be new can exchange with conventional keyboard like this, and more convenient user uses.
