Abstract

The utility model relates to a body study keyboard which comprises a base and a plurality of multiple-row press keys. The multiple-row press keys are provided on the base in a circular-arc. Circle centers corresponding to circular-arc press key columns are in one line. The position where circle centers locate is at the far away side of the users. When using the keyboard of the utility model, the left-right-bending of wrist and shank is within the range of 5 degrees to make the users feel comfortable and unease to lead the users to form the sensation of fatigable.

Description

Ergonomic keyboard

Technical field

The utility model is relevant for a kind of ergonomic keyboard, particularly relates to a kind of button and is disposed at the ergonomic keyboard of base with the adjacent column of circular arc, and the center of circle of these each adjacent key row is arranged on the same straight line.

Background technology

Existing desktop ergonomic keyboard, for the comfortableness of the person's of being used long period of operation can painstakingly be divided into button about two districts, disclosed for the 253rd, No. 740 as the Taiwan patent.Because keyboard main body structure, have to strengthen the volume of whole keyboard, thereby commercially available ergonomic keyboard takies desk-top space very much at present, with regard to modern's living space, the keyboard that volume is little is comparatively suitable beyond doubt, and modern's contact computation machine is chronic, has not only had ergonomic designs, volume but also little keyboard if can have one, will be a big Gospel to the user.

According to medical report research, the keyboard Designing of the most comfortable should be considered following points:

A. the pressure of shoulder burden heal better little, so the placement location of keyboard should be the height that can allow user's both arms easily place, according to the suggestion that measurement against human body is learned, user's the upper arm and the angle of forearm should be controlled at 75～135 spend between.

B. the bending angle about user's wrist shin (wrist) should be in the scope of 5 degree; And tortuous up and down angle should be in the scope of 10 degree.

According to the keyboard of ergonomic designs, still be found in United States Patent (USP) the 5th, 360, a kind of keyboard of No. 280 towards user's bending, be divided into the left side, curved portions and right side, the tangent line of this curved portions and horizontal angle theta are 35 degree shown in Figure 1 as this case, this makes when using keyboard, the wrist shin must be bent to about 17 degree angles, increases user's fatigue easily, and the button of curved portions amplifies in addition, the stroke that knocks of the left and right sides is strengthened, increase user's inconvenience.

The utility model content

The purpose of this utility model is to provide a kind of ergonomic keyboard, and it designs at above-mentioned b point, and when using keyboard of the present utility model, user's wrist shin bends right and left can be within the scope of 5 degree.

The purpose of this utility model is achieved in that promptly provides a kind of ergonomic keyboard, comprising: a base; And multiple press keys, being circular arc row and putting on this base, the center of circle of each row button is arranged on the straight line.

Wherein, the center of circle of this multiple press keys is positioned at the place ahead of this keyboard, and promptly the key columns of this circular arc is given prominence to towards the user.

Description of drawings

Fig. 1 is the synoptic diagram of each key columns configuration of major key panel of the utility model ergonomic keyboard;

Fig. 2 is the enlarged drawing of each key columns configuration of major key panel of the utility model ergonomic keyboard.

Embodiment

Fig. 1 is the major key panel of the ergonomic keyboard of embodiment of the present utility model, and key arrangement of the present utility model is according to the QWERTY keyboard arrangement mode of Qwerty.According to ISO 9241 the keyboard row from top to bottom are called row0, row1, row2, home row, row4 and row5 in regular turn, therefore in Fig. 1, this each keyboard is listed as and is denoted as R0, R1, R2, R3, R4 and R5 in regular turn respectively corresponding to ISO 9241 and launches to be arranged on the base 1, wherein, R0 is the standard feature key row of this keyboard.The center of circle of this each key columns is respectively O, and O1, O2, O3, O4 and O5 are arranged on the straight line A, and the intersection point of A and this each key columns is respectively S0, S1, S2, S3, S4 and S5.

The distance of O and S0 is the radius r 0 of R0 arch section, and the distance of O1 and S1 is the radius r 1 of R1 arch section, and the rest may be inferred, O2 and S2's is the radius of R2 apart from r2, O3 and S3's is the radius of R3 apart from r3, and O4 and S4's is the radius of R4 apart from r4, and O5 and S5's is the radius of R5 apart from r5.Wherein, r0=r1=r2=r3=r4=r5, promptly the arc radius of each key columns equates.

In addition, this each center of circle can equidistantly be arranged on the straight line A, and promptly this each key columns is with the circular arc translation of radius together and form.

Fig. 2 is the enlarged drawing in the ergonomic keyboard major key panel of embodiment of the present utility model.

Ergonomic keyboard of the present utility model comprises a base 1 and multiple press keys R0 to R5, is circular arc row and puts on this base 1, and the center of circle O to O5 of each row button is arranged on the straight line A.This each key columns R0 to R5 is outstanding towards the user.So, with design of the present utility model, when using this keyboard, user's wrist shin bending can not surpass 5 degree, reaches and avoids the user to produce tired effect.

Claims
