KEYBOARD - KNAPPSAT

The invention relates to a keypad for controlling, for example, a mobile phone, a telephone, a calculator, a radio, a tape recorder, a player or another device which requires the control of numeric buttons 1,2, 3, 4, 5, 6, 7, 8, 9, 0 and some additional buttons.

Commonly used keyboards have three buttons in four overlapping rows, and have the numbers 1,2, 3, 4, 5, 6, 7, 8, 9, 0 and two additional function buttons. The buttons are arranged in three numeric buttons 10 side by side, starting from one top or bottom left and continuing in numerical order. Zero is placed in the same row as the additional function buttons. Outside this grouping, various additional function buttons are usually placed according to the needs of the device. In practice, using existing keyboards requires shifting your gaze to the keyboard to find the right first-15 button, as well as generally moving your finger from one number to another, thus binding the visual sense, for example, when driving a car.

It is an object of the invention to provide a keypad that the user does not need to look at, but is operable mainly on the basis of tactile sensation and generally known form. The features of the keyboard according to the invention are detailed in the appended claims.

The advantages of the invention over commonly used keypad models are: * 25 The process of figuring out numbers clockwise is learned at an early stage and is thus a familiar order for users. The radial ridges on the buttons act as guides through which the finger can be moved through the center of the keyboard or directly to the next button via the tactile sense. The double crest of the numbers 3, 6 and 9, as well as the different tactile surface of the function keys, and the deeper or higher positioning of all 30 facilitate the initial positioning of the finger on the keypad, visualization of the dial face, and finger positioning. It is an object of the invention to provide a keypad which can be operated mainly by means of tactile sensing and clock face rendering and can thus be placed in positions which are not viewable during keying, e.g.

In the following, the invention will be described in more detail by way of example with reference to the accompanying drawing, in which Figure 1 shows a keyboard according to the invention, Figure 2 shows a keyboard in section 9-3 and Figure 3 in section 3-9.

In the invention, the buttons are arranged in a circle on a clock face. The number one is at the same position as the number one on the watch face, and the zero is at the position where the number on the watch face is ten. Eleven and twelve digits on the dial face 10 additional function buttons placed in the center of the circle. The buttons on the keyboard have an elongated shape: sectors and extend radially from the center of the circle to the periphery of the circle.

The keypad can also be configured to improve fingerprinting by having buttons 1, 2, 4, 5, 7, 8, 0 shaped longitudinally (radially -155a) in a tactile, oblique V (b) cross section and buttons 3, 6, 9 in the shape of the inverted W (a). The auxiliary function buttons at the dial 11 and 12 are in the shape of an inverted W or a truncated V (c). The center auxiliary button is circular (d) and has a tactile surface.

Buttons 1, 2, 4, 5, 7, 8, 0 are slightly higher or lower than the other buttons. The buttons are pressed along the entire length or, alternatively, at the outer peripheral end.

'25 Of course, one of ordinary skill in the art will appreciate that the design of the tactile surfaces of the buttons may also be other than those set forth above, and if necessary, additional additional function buttons may be located outside the keyboard. The keyboard can also be shaped as a mirror image for use inside out.

Claims (5)

1. Keypad for controlling eg. a mobile phone, a telephone, a calculator, a radio, a tape recorder, an instrument or other apparatus, for controlling which number press buttons 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 and several additional push buttons (a, b, c), characterized in that the push buttons (a, b, c) have been placed in a circle according to the bell model so that the push button one is in the same place as the number one in the bell board and noli is in one place , which has the number ten in the bell board, and that in places of the bell number eleven and twelve and in the middle of the circle, pushbuttons have been placed for additional functions (c, d), or that the keypad has been placed as a mirror image of the bell board for use. 2. Keypad according to claim 1, characterized in that the push buttons (abc) in the keypad are in the form of longitudinal sectors and continue generally from the center of the circle to the circle of the circle, and that the push buttons press for their entire length or alternatively at the end. of external circuits. 3. Keypad according to claim 1, characterized in that in order to improve the fingertip feel in the keypad, the buttons 1, 2, 4, 5, 7, 8, 0 (b) | have been formed longitudinally (in radial direction) by their sensing surface so that they are shaped, to the shape in cross-section as a wavy V (b) and the pushbuttons 3, 6, 9 (a) to the shape in cross-section as a wavy W , that the pushbuttons for auxiliary functions at the locations 11 and 12 of the clock board are in cross-section have a shape of a wavy W or cut V, and that the pushbutton for auxiliary functions in the middle (d) is round and sensitive to its sensing surface. 4. Keypad according to claim 1 or 3, characterized in that; the pushbuttons 1, 2, 4, 5, 7, 8, 0 are a little compared to the level of other pushbuttons. . 30 higher or lower. in 5.
