Description

The This invention relates to convertible computers, the "convertibles", which can switch between the notebook and tablet PC modes

externally The convertible looks like an ordinary notebook. In the basic block of the notebook are a keyboard and a touchpad built-in. But he differs from the notebook in that The notebook's screen is characterized by a special hinge that It connects to the base block, 180 ° around the horizontal Axis and 180 ° can rotate around the vertical axis, but so that the display completely closes the keyboard.

So can the convertible in the mode of the tablet PC convert, and data entry can be with a Digiteiser or with the on-screen keyboard. An example of such devices is the Fujitsu Siemens Computers Lifebook P1510 or the ASUS Eee PC T101H.

The low speed of data entry is a significant shortcoming of the tablet PC because the user has no way Use the keyboard and touchpad as they pass through the display are covered. Besides, the user can only input with one hand, because he is with the other hand holding the computer.

There are models of tablet PC, where you can disconnect the keyboard from the basic block. Such tablet pc is in DE 103 14 555 A1 2004.10.14 described by the inventor Swiss, Joachim, Munich, DE. The tablet PC according to the invention has a removable keyboard. This achieves the function of a full-fledged desktop PC. But this loses all the benefits of the tablet PC.

• – Bei der Transformation der Vorrichtung aus dem Notebook in den Tablett-PC schließt das Display nicht die Tastatur des Convertable und bleibt zugänglich für die Hände des Benutzers;
• – Die Tastatur mit auf ihr gelegenem Touchpad ist die abgesonderte Konstruktion, die sich im Modus des Notebooks bezüglich des Basisblocks frei bewegen kann. Im Tablett-PC-Modus ist diese Tastatur mit dem Basisblock fest verbunden und gewährleistet dem Benutzer die Möglichkeit mit zwei Händen mit der Tastatur und Touchpad zu arbeiten, und währendessen die Vorrichtung festzuhalten;
• – Die Datenübertragung von der Tastatur und des Touchpads zum Computer wird bei allen Transformationen nicht unterbrochen.

In the invented device, none of the above disadvantages are present. In Tablet PC mode, the user can insert the data into the computer using the Convertible's own keyboard and touchpad. For this purpose of the invention it is provided that:

• - In the transformation of the device from the notebook into the tablet PC, the display does not close the keyboard of the convertible and remains accessible to the user's hands;
• - The keyboard with a touchpad located on it is a separate construction which can freely move in the mode of the notebook concerning the basic block. In tablet PC mode, this keyboard is fixed to the base block and allows the user to work with two hands on the keyboard and touchpad, while holding the device in place;
• - The data transfer from the keyboard and the touchpad to the computer is not interrupted in all transformations.

For become the full understanding of the invented device the following drawings and footnotes are used. The footnotes, numbered from the identical numbers on all drawings are related to one and the same drawings.

1 The type of device on average.

2 Represents an isometric view of the device with open display

3 Device in notebook mode.

4 Two-axle pendulum hinge on average

5 Device in tablet PC mode.

6 The type of caption on the keys of both parts of the keyboard.

On 1 the side view of the invented device is shown schematically. On 1.1 the device is in the transport state. the display 1 , which is also the lid for the computer, and the base block 2 , along with the keyboard attached to it 3 , are mutually biaxial pendulum hinges 4 connected to the display 1 Allow yourself to 360 ° around the base block 2 until the display is at the bottom of the base block 1.2 ,

On 2 In an isometric view, the open display device is shown ready for conversion from the transport state to the notebook mode or tablet PC mode. As in 2 is shown in the keyboard that uses the QWERTY keyboard layout divided into two parts, one left 3.1 and a right part 3.2 , A similar construction of the split keyboard is in the patent US D585,063 p Jan. 20, 2009 and produced under the trademark Freestyle Solo ^TM Applications by the American company Kinesis Corporation.

The left part 3.1 and the right part of the keyboard 3.2 can in notebook mode relative to the basic block 2 move freely.

In Tablet PC mode, these parts of the keyboard are on the front of the basic block 2 is assigns. They will be attached to it with the help of pins with latches 5 and 6 and the castle 7 fixed so that the rows of keys parallel to the sides of the base block 2 are located.

• – Links vom Bildschirm – die Halbe Space-Taste – Alt – Win Key – Ctrl (Strg).
• – Rechts vom Bildschirm – die Halbe Space-Taste – Alt Gr – Win Key – Menu – Ctrl (Strg).

On the left part of the keyboard 3.1 There is a TouchPad besides the keys 8th with two buttons and with the scroll wheel. To the right and to the left of the screen are two groups of buttons 9 arranged, just such keys have the same function as the keys of the sixth row of keys of the standard keyboard and space key. They are in the following order above - down:

• - Left of the screen - the Half Space key - Alt - Win Key - Ctrl (Ctrl).
• - Right of the screen - the Half Space key - Alt Gr - Win Key - Menu - Ctrl (Ctrl).

Both Halves of the space key work absolutely the same, too if only one Space key is pressed. Furthermore All keys are identical to those of a normal keyboard.

On each of the pages of the basic block 2 there is a noose 10 , These slings can be Removable shoulder straps such as a camera, or individually adjustable hand straps 11 Attach.

From the open state in which the device is located, see 2 , it can be converted in the two modes. To convert to notebook mode you have to lock 7 open and the left part of the keyboard 3.1 90 ° counterclockwise around the pin 5 and the right part of the keyboard 3.2 90 ° clockwise around the pin 6 rotate. As a result, both parts of the keyboard form into a standard keyboard and the computer can look like a regular notebook, as shown in FIG 3 be used. In this location, the pawls can 5 and 6 to release the keyboard from the pins and move it freely from the base block, for example, allowing to set the optimal distance between the user's eyes and the screen.

For the conversion of the device in the tablet PC mode remain both parts of the keyboard 3.1 and 3.2 in their transport position, where they are at the base block 2 are attached. the display 1 turns with the help of the pendulum hinge 4 with respect to the basic block 2 360 ° until the end of the possible rotation.

The construction of the pendulum hinge will be in 4 shown on which the cross-section of the hinge is presented. On the drawing is visible that the hinge is a central band 12 represents the general detail of both lateral joints 13 and 14 with the axes 15 and 16 is appropriate. Similar constructions of the pendulum hinge can be found in doors in public spaces (for example, railroad stations and subway stations), ie everywhere where large streams of people use the door, which opens up to 180 ° in each direction. In the offered device, the display is fixed by a pendulum hinge with the base block.

In the tablet PC mode can to the slings 10 individual hand straps 11 be attached. The user turns Tablet PC screen to himself and pushes his hands through the loops 11 by. The user includes the tablet PC with the palms on the sides so that there are two thumbs at the top of the display and eight remaining fingers at the bottom of the keyboard. The thumbs of the user work with the half space key and the keys 9 , which are attached to the left and right of the screen, and the remaining fingers of both hands work with the keys that are on both parts of the keyboard 3.1 and 3.2 and the TouchPad 8th are located. The straps and the individually adjustable hand straps 11 only fulfill a backup function that prevents the tray PC from falling to earth. Thus, the device allows the user to hold the tablet PC in two hands and at the same time by all the fingers of both hands, to insert into it the data from its own keyboard and to control the cursor by means of the TouchPad. With such an arrangement of the palms and fingers of the user and the keyboard is very ergonomic because the user does not bend his hands. It also contributes to the prophylaxis of the occupational disease of programmers and operators, the Carpal Tunnel Syndrome (CTS), due to the lengthy and inconvenient work with the keyboard. The user works in this mode on the keyboard like a musician who plays on an accordion.

The keyboard caption is mirrored. In the left part of the keyboard Fig. 3.1 the symbols on the keys are turned 90 ° clockwise and on the keys of the right part of the keyboard Fig 3.2 the symbols are rotated 90 ° counterclockwise as it is on 5 is visible. It is meant for an inexperienced user to quickly learn to work blindly on such a keyboard. To do this, the user should take the tablet PC, and stand in front of a mirror and, working in the mirror, learn to work on the keyboard. In Notebook mode, the keyboard caption is mirrored and rotated 90 degrees, but this is not a big deal.
