Abstract

The utility model discloses a pedal key for a computer, which can raise input efficiency in a computer input aspect. The pedal key for a computer solves the problem of the complicated process operation of the mutual switches of Chinese characters-ASCII character and ASCII character-Chinese characters in the process of Chinese characters input. The utility model mainly comprises two parts of a circular order switch and a pedal box. The utility model, which has the advantages of realization of fast switch function by the action of feet, time saving, high efficiency, simple operation and convenient operation, is accorded with human body engineering principle.

Description

Pedal key for computer

The utility model belongs to computer entry device, especially a kind of foot-operated key of being made up of circular order switch and foot-operated box of computing machine.

At present the time to computer input of Chinese characters, particularly when the input scientific and technical literature, Chinese character and ascii character are used alternatingly, (being called for short the Chinese-A switches so Chinese character-ascii character switches, as follows) and ascii character-Chinese character switches (be called for short the A-Chinese and switch, be as follows), and relatively frequently, every switching once all will just can be finished by keystroke by four times, both pinned " Alt " key earlier and hit once " F6 " key again, and then unclamp " Alt " key and finish the Chinese-A switching.Still pin " Alt " key again during the switchback Chinese character earlier, (present embodiment is " F4 " key to hit once " F4 " key again, difference according to input coding for Chinese character, also can be other function keys), and then unclamp " Alt " key and finish the switching of the A-Chinese, above operating process is more loaded down with trivial details, needs the good fit of both hands and eye, switch speed is slow, causes that easily operating personnel slip up and fatigue.

The utility model can provide a kind of computing machine to ride key, and it can finish above-mentioned loaded down with trivial details handoff procedure easily by the mode of foot-propelled.

To achieve these goals, the solution that the utility model adopts is: every docking point of " Alt " key, " F6 " key and " F4 " key on the computer keyboard is drawn with lead respectively, be attempted by on the foot-operated corresponding every docking point of key circular order switch.According to the transfer sequence principle of manual keyboard, form the circular order switch with the slide block, slide, fork, balance staff, escapement and the sequence contacts that have the circulation back stop slot etc., constitute the foot-operated key of computing machine together with foot-operated box again.Under foot-operated, can realize that the Chinese-A switches, switch when pin lifts and can realize the A-Chinese.Thereby substituted manually loaded down with trivial details action, realized the purpose of quick input rapidly easily by keystroke four times.

The foot-operated key of computing machine of the present utility model has novel, simple in structure, makes, installs easily, and is easy to operate, more meets the ergonomics principle, operating personnel's indefatigability, advantage such as increase work efficiency.Its birth will be subjected to numerous computer operators' welcome.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is one-piece construction figure of the present utility model.

Fig. 2 is the left view of Fig. 1 circular order switch.

Fig. 3 is that partial view is looked on the left side of slide block among Fig. 1 (7).

Fig. 4 is Fig. 3 back stop slot ab curve stretch-out view that circulates.

Fig. 5 is a circular order make and break contact wiring diagram.

Calculating under-chassis in Fig. 1, Fig. 2 steps on key and mainly is made up of circular order switch and foot-operated box two parts.The circular order switch is made up of button (6), slide block (7), back-moving spring (8), slide (9), bearing pin (5), fork (4), balance staff (3), escapement (2), insulating barrier (12), sequence contacts (13), insulating mat (15) and insulation screw (14).Foot-operated box is made up of box body (10), base (11) and screw (1).The circular order switch is fixed together slide (9) and base (11) by screw (1) (among the figure 2).Box body (10) is fitted together by the convex-concave step on the seam with base (11).Sequence contacts (13) (being 8 flat spring sheets among the figure), insulating barrier (12) (among the figure 2), insulating mat (15) (among the figure 4) are separately fixed at the step both sides of slide (9) by insulation screw (14) (among the figure 4).Bearing pin (5) is fitted together with fork (4) riveting, is contained on the slide (9).Balance staff (3) is fitted together, is contained in by slide (9) in the circulation back stop slot of slide block (7) with fork (4) and escapement (2) (insulation wheel) riveting.Fig. 5 is a circular order make and break contact wiring diagram, and " Alt ", " F6 ", " F4 " are in parallel with the contact of the same name on the computer keyboard respectively.Fig. 3, Fig. 4 are the partial view and the ab curve stretch-out views of slide block (7) circulation back stop slot.Slide block (7) is when moving up and down, because (it is enclosed within the upper end of fork (4) at back-moving spring (8), play location and suppressing action) and fork (4) (it is manufactured by flexure strip, work to press down balance staff (3), the lower end that makes balance staff (3) contacts with circulation back stop slot bottom all the time) effect under, balance staff (3) is driven by the circulation back stop slot and makes clockwise cycle rotation by designing requirement, realizes swinging.

In Fig. 1, Fig. 2, Fig. 3, Fig. 5, (because the effect of back-moving spring (8) when riding button (6), the initial position of escapement (2) is a mid point in b point groove) slide block (7) moves down, the circulation back stop slot drives balance staff (3) left side pendulum, escapement (2) compressing " Alt " reed, connect " Alt " key earlier, connecting " F6 " key again by insulating barrier (12) promotion " F6 " reed, along with the following of pin stepped on, it is mid point that escapement (2) right side is put in a point groove, realize that the Chinese-A switches, this moment is foot-operated lives that button is motionless can import ascii character.When pin lifts, because the effect of back-moving spring (8), slide block moves on (7), and the right pendulum compressing of escapement (2) " Alt " reed is connected " Alt " key earlier, promoting " F4 " reed by insulating barrier (12), connect " F4 " key again, along with lifting finishing of foot-propelled work, it is mid point that escapement (2) is put back in b point groove, realize that the A-Chinese switches, can import Chinese character this moment again.Having stepped on of above pin once can realize the Chinese-A-Chinese handoff procedure, finishes on the manual keyboard four times by the keystroke process, thereby realized improving the purpose of input speed.

Transfer sequence principle according to computer keyboard, as with " Alt " contact reconfiguration " Control " contact on keyboard among Fig. 5, with after " F6 ", the parallel connection of " F4 " contact, reconfiguration " F9 " contact on keyboard can realize that again full-shape-half-angle-full-shape switches again.According to user's different needs, the different contacts on the reconfiguration keyboard just can be realized different functions.So the foot-operated key of this computing machine can be realized the function that a key is used more or multikey is used more.

Certainly, realizing that above-mentioned functions is not limited to a kind of form, can also be other form.
