DE102008022906A1 - Foldable flat screen for e.g. presenting content of school book to child, has operating elements selecting and changing text and/or image information, which is produced in upright format, in arrangement, shape, color and sequence - Google Patents

Abstract

The screen (A) has a control electronics, an accumulator, a battery or power supply, where an identical flat screen (B) is attached to a long side of the screen (A) by a hinge device (5). The screen (B) with an active screen surface lies on a screen surface of the screen (A) with or without safety distance in a closed position. One or both screens produce text and/or image information in upright format in an open position. Operating elements (6, 7) select and change the information in arrangement, shape, color and sequence.

Description

It a proposal is made, such as the weight load by Books in the schoolbag, the office bag and other containers can be reduced.

Children, the z. For example, to attend high school, you have to be with about 10 ... 15 kg of book weight tormenting the daily burden your satchel, since regularly the Timetable for about 4-6 Hours of presence from almost all textbooks forces. This is especially for girl In the first years of school an imposition that leads easily to postural defects, such as Orthopedists assure.

The product idea described below provides a remedy. A flat screen - foldable in the middle like a book - with memory sticks presents every content of a book, brings the weight of z. For example, 6 textbooks down to just 1 kg - not to mention the volume saved, which shrinks from 6 books to about 1 book. ( 1 )

The Product idea is not to be confused and compare with so-called. e-books that require laptops or notebooks or desktops to visualize them if you can not do a presentation with a cell phone, ipod or similar devices prefers.

The foldable screen is deliberately designed like a book (2 pages side by side in portrait format) so that the book relationship is highlighted and in the folded state, the risk of breakage is excluded. He can be laid down and also put up. Not only textbooks, but also textbooks, the simultaneous display of 2 pages is often required if z. B. one page is a construction or an image representation and the other side is an explanation. This meets z. For example, too, when patent literature must be judged. ( 2 )

On Traveling with long flight or train times, it is more convenient a screen book to scroll as a few kilograms of business To carry around original correspondence.

If an exciting novel should also be read in bed, does not bother a laptop still the reading lamp, as well as the brightness of the folding screen can be adjusted.

Also Scores for Orchestra can instead of transport-consuming Papers over Foldable screens presented become.

All Generally, the effort is for Packaging, transport, storage of text and image by means of storage Significantly lower, if transported in just one "book" any amount of content can be.

Furthermore brings the described "version of books "a distinct Reduction of consumption of natural resources.

You are always independent of notebook, laptop, desktop computer or internet. ( 3 )

Not last can Equipment manufacturers and providers expect a program extension.

There self-sufficient small screens for the playback of digital photos currently already inexpensive can be expected that is also the cost side do not bother becomes. The development of flexible screens will also be positively affect.

The Production of textbook and textbook content in memory sticks might both in terms of cost and flexibility to have a positive effect.

The power supply of the read screen by means of supporting solar foils ( 1 2 ) also contributes to the contemporary use of modern information technology.

A Reducing the weight and volume of children and adults, the flexibility the application and the use of solar energy are sufficient motivations for positive Future prospects.

The foldable flat screens can made in different sizes the focus should be at sizes of about DIN A4 to about DINA 5 lie.

The equipment is also variable, like 4 . 5 u. 6 demonstrate.

drawings

1 , shows by way of example a version of the article according to the invention in which a screen A ( 1 ) and a screen B ( 2 ) via hinges ( 5 ) are pivotally attached to each other. Necessary electrical connections between A and B are made via rotary contacts ( 5a ) performed.

The frames ( 3 ) ( 4 ) leave room for controls ( 6 ) ( 7 ) and memory sticks ( 7a ). At ( 8th ) is a touchscreen part of the screen indicated at ( 9 ) Keys are provided for operation.

A solar foil ( 13 ) is via contact hinge ( 14 ) involved in the energy supply. With a mounting bracket ( 16 ) can read the screen be brought position.

2 , It makes clear how little volume is taken from the screen, considering that memory modules can easily store a lot of information without increasing the weight and volume of the screen. The outer sides can be covered with solar foils ( 15 ) be equipped.

3 , shows a half-opened screen. ( 10 ) ( 11 ) ( 12 )

4 , illustrates how a back piece ( 19 ) - similar to a spine - all necessary electronic components ( 22 ) ( 23 ) for the operation and control of the screen. The two screens ( 17 ) ( 18 ) are hinges ( 20 ) ( 21 ) connected to the back part.

5 , So the two screens ( 24 ) do not fold apart during transport, they are z. B. via a zipper ( 25 ) ( 26 ) coupled together. This can also be done by means of magnet, push button or latch. Hinge rail ( 32 ).

6 , shows one way the flat screen ( 27 ) ( 28 ) vertically and simultaneously over the base ( 29 ) with support ( 30 ) as well as the functional elements ( 31 ) to cause the charging of the batteries as an energy source and the transfer of information content to the memory sticks.
