Abstract
The utility model belongs to a peripheral device for computers, which is an improved computer keyboard. According to the arrangement of keys, a main body of the keyboard is split into a left section and a right section which are arranged in an inverted V shape. Both of the two sections can be arranged in a symmetrical arc shape or a symmetrical parallelogram shape, and the arrangement mode accords with the inverted-V-shaped natural mode that the hands are placed in front of the body. An inner side edge of the keyboard is also provided with a raised arc-shaped hand supporting board. When the keyboard is used, wrists of an operator are naturally and comfortably placed, so that the fatigue is lessened and the utility model is favorable for increase of operation speed.
Description
The utility model belongs to computer peripheral, is a kind of improved computor-keyboard.
At present, control and input keyboard that computer is used are shaped as rectangle, and its main part button (being letter key, symbolic key, numerical key etc.) is neat square formation formula and arranges, and as shown in Figure 1, the button in the frame of broken lines is a main part.When people's two hands were placed on before the body naturally, two forearms comprised that wrist becomes Eight characters shape, and when two hands are operated on above-mentioned computor-keyboard, make wrist reverse certain angle, even wrist is in a kind of factitious state, thereby make wrist feel uncomfortable, and fatiguability.In addition, toward have a down dip, during operation, can only lift, more increase the sense of discomfort of hand from outside to inside by wrist for the key position of above-mentioned keyboard.These factors also will influence the raising of operating speed.
The purpose of this utility model is to design a kind of key arrangement and the consistent computor-keyboard of two hands state of nature before body, so that reduce the sense of discomfort and the sense of fatigue of operator's wrist, improves operating speed.
The computor-keyboard of the utility model design is connected to form through circuit by plate, button, and the quantity of its button, function and common keyboard are consistent, and it comprises function key, numerical key, letter key, operating key etc.Wherein, the main part button on the keyboard is divided into left part and right part, and becomes splayed to arrange, as shown in Figures 2 and 3.This arrangement mode of button and the two hands state of nature basically identical before body.Operator's wrist posture when operation is natural, comfortable, can alleviate the degree of fatigue of wrist, improves operating speed.
The computor-keyboard of the utility model design, two parts that its main part button splayed is arranged can be the arc shootings of symmetry, as shown in Figure 2, also can be that the parallelogram of symmetry is arranged, as shown in Figure 3.The arrangement of these two kinds of forms is comparatively attractive in appearance, also is suitable for the operation of pointing comparatively naturally.
In addition, the keyboard of the utility model design, its inboard (near a side of the person) edge designs has the hand-rest plate of arc protuberance.When operation, wrist can be put on hand-rest plate naturally, makes the operation of light finger loose ground, thereby can lessen fatigue degree to greatest extent, helps long-time operation, helps improving operating speed.
Fig. 1 is existing computor-keyboard structural drawing.
Fig. 2 divides the camber symmetry computor-keyboard structural drawing that splayed is arranged for the main part button.
Fig. 3 is divided into the computor-keyboard structural drawing that parallelogram symmetry splayed is arranged for the main part button.
Fig. 4 is the keyboard transverse sectional view.
Wherein 1 is plate, and 2 is button, and 3 are arc protuberance hand-rest plate.
Claims (3)
