Description

The present utility model relates to a keyboard, in particular to a keyboard with an ergonomic design with rational use of space.

BACKGROUND OF THE INVENTION

In modern society, computers are widely used to process data or other tasks, such as processing spreadsheets. Therefore, to facilitate this work, data entry devices into the computer are important. For example, a mandatory device for entering data into a computer is a keyboard. In figures 1-3 presents a regular keyboard 10A. As shown in these figures, the keyboard 10a comprises a plurality of keys, and a cap of keys is located on each key. The key caps are staggered, and each one has a rectangular shape. However, the user's hands are naturally set under oblique directions with respect to the vertical center line of the keyboard 10a. The user often has to turn his hands inward to press keys located close to the vertical center line of the keyboard 10a, as shown in FIG. 3. Therefore, the user often has pain after prolonged printing.

SE3269 KEYBOARD

the keyboard 20a generally has a main print area 21a, and the keycaps 211a of the keys in the main print area 21a are also rectangular. In addition, the main printing area 21a is divided into the left section 22a and the right section 23a so that the user can more ergonomically place their hands on the keyboard. However, this inevitably creates unused space in the central part of the ergonomic keyboard 20a. The area occupied by the ergonomic keyboard 20a increases so that the ergonomic keyboard 20a is not suitable for laptop computers.

Brief Description of the Invention

The real utility model is aimed at a keyboard with an ergonomic design that allows rational use of space. Such a keyboard is suitable for a desktop computer, laptop computer, and cash registers.

To achieve this, a true utility model is aimed at the keyboard. The keyboard contains the main print area, which houses a lot of keyboard caps. Keycaps are divided into many rows by many horizontal lines. Keycaps are divided into the left section and the right section with the center line of the keyboard separating them. Each cap in the left section has a quadrangular shape with the upper side offset to the right and the lower side offset to the left; each cap in the right section has a quadrangular shape with the upper side offset to the left and the lower side offset to the right.

DETAILED DESCRIPTION OF THE INVENTION

As shown in FIG. 5, the real utility model is aimed at a keyboard with an ergonomic design that does not take up much space. The keyboard 1 in accordance with a preferred embodiment of the present utility model also comprises a main printing area 11, in which a plurality of character keys, a plurality of alphabet keys, a plurality of auxiliary function keys, and a space bar are arranged. The main printing area 11 is divided into a plurality of rows by a plurality of horizontal lines. In this preferred embodiment of the present utility model, the main printing area 11 is divided into five rows by four horizontal lines L1, L2, L3 and L4. The keys in the main printing area 11 are arranged similarly to a conventional keyboard and are divided into two sections, that is, into the left section 12 and the right section 13. The keys 121 of the keys in the left section 12 are in the form of a parallelogram with the upper part, shifted to the right, and the lower part, shifted to the left; while the upper part and the lower part of the key cap 121 are parallel to the horizontal lines L1, L2, L3 and L4. In addition, each cap 131 in the right section 13 is in the form of a parallelogram with the upper part shifted to the left and the lower part shifted to the right; while the upper part and the lower part of the key caps 131 are parallel to the horizontal lines L1, L2, L3 and L4. In addition, the main printing area 11 includes the leftmost key cap 122 located on its left side and the right-most key cap 132 located on its right side. Most

area that facilitates printing. Therefore, the user is prevented from pain during prolonged printing. In addition, as shown in FIG. 8 and 9, each cap 121 of the function keys in the left section 12 and each cap 131 of the function keys in the right section 13 are made in the form of a parallelogram with an ergonomic tilt direction. The section between two adjacent keys can be reduced to reduce the distance of hand movement. Therefore, the user is prevented from feeling pain during prolonged printing.

In FIG. 10 shows yet another preferred embodiment of the present utility model. The keyboard in accordance with this utility model is the keyboard 21 of a computer type 2 laptop. Similarly, the keyboard 21 of a laptop computer 2 of a laptop type is divided into a left section 211 and a right section 212. Each keycap in the left section 211 is in the form of a parallelogram with the upper part shifted to the right and the lower part shifted to the left; each key cap in the right section 212 is in the form of a parallelogram with the upper part shifted to the left and the lower part shifted to the right. The keyboard 21 of a type 2 laptop computer has ergonomic properties without increasing the space occupied by the keycaps.

In general, the keyboard, in accordance with this utility model, has a modified shape to provide ergonomic properties without increasing the space occupied by the keycaps. The keyboard, in accordance with this utility model, is not bulky and can

used in desktop computers, laptop computers and cash registers.

Although the present utility model has been described with reference to its preferred embodiments, it should be understood that the present utility model is not limited to their details. In the foregoing, various replacements and modifications are possible that will be apparent to those skilled in the art. Therefore, it is assumed that all such replacements and modifications will be covered by the scope of the present utility model, which is defined in the attached utility model formula.
