Abstract

The technical result of the utility model is to increase the ergonomics of the operation of the keyboard due to the ability to move the user's fingers more vertically, as a more natural physiological trajectory of the fingers is achieved by the fact that in a well-known keyboard containing a housing, an input-output connector, a field of letters with letters, numbers, control commands, downstream printed circuit boards and an isolating dielectric, the field of keys with letters is made split, so that the upper and lower rows of keys with b ukvami are placed on movable plates, the upper one with the possibility of shifting by 1/3 of the width of the key to the right, and the lower one with the possibility of shifting by 2/3 of the width of the key to the left, forming, with alphabetic keys of the middle row, columns vertically located on the keyboard plane perpendicular to the horizontal rows of keys, while the contact areas below the printed circuit boards and the through holes of the intermediate dielectric complementary to these areas are horizontally oblong, with a length equal to the shear value of the plates.

Description

This utility model relates to the field of computer technology, and, in particular, can be used in the design of computer keyboards.

Currently, the well-known computer keyboard contains a housing, an input-output connector, keys with letters, numbers and control commands set similarly to their location on a typewriter

A computer keyboard is known, comprising a controller, a data processing device and keys, in the keyboard heads of which a mini-display is placed, the screen of which faces the front surface of the keyboard head, see patent No. 2214619, “Keyboard, key, method for outputting and changing characters on keyboard keys electronic device "G 06 F 3/00, 2001.07.20.

The closest in technical essence to the claimed device is 101 - an IBM PC keyboard containing an alphanumeric part, function keys and a numeric keypad, see K. Akhmetov, Course of a Young Fighter ", M. 1996, p. 379.

Here, the keyboard lettering is arranged in three rows. To create and transmit information signals in a computer, two folded electrical circuits on printed circuit boards are used, separated by a thin dielectric with through holes located under the centers of the keys.

However, the known keyboard has a significant functional drawback.

For historical reasons of a technical nature, the letter keys of the three rows are not exactly under each other, but form short, inclined three-key links.

This arrangement of letter keys was created during the creation of the first mechanical typewriters.

By virtue of the only mechanical means of transmitting motion that were available at that time, each key had to be connected by a mechanical chain of levers, rods, and hinges to the corresponding letter head. A large number of levers, which should be placed in a limited space, forced the keyboard creators to place the letter keys not in the form of an orthogonal symmetric scheme of horizontal rows and

short three-element columns perpendicular to them, and in the form of three-element links, inclined with respect to horizontal rows.

Thus, the keys of the upper row were not exactly above the corresponding keys of the middle row, but were forced to shift one third (1/3) of the width of the key to the left, while the keys of the lower row were shifted by two thirds (2/3) of the width of the key to the right with respect to the middle row keys.

Due to such forced irrational arrangement of the keys, the operator’s fingers, which are in a ready state above the middle row keys, cannot reach the upper and lower row keys by simple orthogonal movements. To reach any key of the upper or lower row, lateral, less natural and more complex finger movements are required.

Although the delay with each hit is hundredths of a second, the data input speed is generally reduced, which objectively reduces the overall efficiency of using the well-known keyboard.

The purpose of the claimed utility model is to provide a technical result to increase the ergonomics of the operation of the keyboard by providing the ability to move the user's fingers along a more natural physiological path of the fingers.

The specified technical result is ensured by the fact that in the well-known keyboard comprising a housing, an input / output connector, a key field with letters, numbers, control commands, downstream printed circuit boards and a dielectric, it is proposed that the key field with letters be split so that the upper and lower rows of keys with letters were placed on the movable plates, the top with the ability to shift 1/3 of the width of the key to the right, and the bottom with the ability to shift 2/3 of the width of the key to the left, forming, with alphabetic keys, the middle row vertically located on the keyboard plane, columns perpendicular to the horizontal rows of keys, while the contact zones of the upper and lower alphabetic rows below the printed circuit boards and the through holes of the intermediate dielectric complementary to these zones are horizontally oblong, with a length equal to the plate shift values.

The claimed utility model is illustrated by graphic materials.

Figure 1 shows the design of a traditional keyboard (with lettering), Figure 2 - design of the proposed keyboard (with lettering), Figure 3 - a fragment of one of the printed circuit boards for the proposed keyboard design, Figure 4 - a fragment of the design intermediate dielectric.

The design of the keyboard consists of a housing 1, on the outer surface of which are buttons 2 keys with letters, numbers and control commands. The buttons of the keyboard letter field are located on the movable, upper 3 and lower 4 plates.

Under the keys are the upper 5 and lower 6 printed circuit boards with contact zones 7 and an intermediate dielectric 8 with through holes 9 between the latter. In this case, the contact zones 7 of the printed circuit boards 5, 6 and through holes 9 of the dielectric 8, located under the upper and lower rows of buttons, are horizontally oblong.

With the proposed keyboard work as follows.

Working with a keyboard with a traditional arrangement of letters, see Figure 1 is carried out in the usual way.

When switching to a keyboard with letters arranged vertically, one above the other, the keyboard is rebuilt. To do this, the top 5 plate with letters is shifted 1/3 of the width of the key to the right, and the bottom 6 is shifted by 2/3 of the width of the key to the left.

After that, the letters are arranged in vertically arranged columns, see Figure 2.

The operator places his fingers traditionally above the middle row of the letter field of the keyboard.

When entering information into a computer using the proposed keyboard, the operator’s fingers are much more likely to make natural movements up and down and much more inclined movements. Thus, the movements on the proposed keyboard are more comfortable than when working with a traditional keyboard.

This design contributes to its easy memorization and faster work. The letters E, H, I and T are also easily accessible due to the higher mobility of the index fingers.

In general, the movements of the operator’s fingers on the new keyboard become more rational, economical along the trajectory, i.e. ergonomic, objectively saving thousandths or even hundredths of a second at each press.

Given that most people are accustomed to working with a traditional keyboard, then retraining to a new register will occur gradually.

For those who do not want to work with the new keyboard, the upper and lower rulers remain in the same places.

The claimed solution can be implemented at any mid-level instrument-making or radio engineering enterprise, which indicates the compliance of the claimed utility model with the patentability criterion of industrial applicability.
