The connection/s is/are to be embodied in an articulated manner, and the joint/s is/are to be configured so as to allow the rotational/swiveling movement/s to be performed about more than one axis, whereby the screens of the additional screen/s can be pivoted at different angles compared to the axis of the first screen, also onto the screen plane opposite the first screen and at different positioning angles.

Description

Mobiler Computer mit zwei oder mehr Bildschirmen.Mobile computer with two or more screens.
Die vorliegende Erfindung beschreibt eine Vorrichtung, die die Präsentation von digitalem Bildmaterial erleichtert. An einem mobilen Computer werden mehrere Bildschirme so befestigt, dass die Bildschirme aus verschiedenen Richtungen einsehbar sind, aber fest mit dem Gerät verbunden ist und über dessen Energiequelle versorgt werden können.The present invention describes a device that facilitates the presentation of digital imagery. On a mobile computer, multiple screens are mounted so that the screens can be viewed from different directions, but are firmly connected to the device and can be powered by its power source.
Die vorliegende Erfindung betrifft eine Vorrichtung in der mehrere Flachbildschirme fest aber beweglich an einem mobilen Computer montiert sind.The present invention relates to a device in which a plurality of flat screens are fixedly but movably mounted on a mobile computer.
In der heutigen Zeit werden zunehmend computergestützte Bildwiedergabesysteme zur Präsentation und Beratung, insbesondere im Außendienst, verwendet. Hierzu werden tragbare Computer verwendet. Diese weisen jedoch nur einen fest montierten Flachbildschirm auf.Today, computer-assisted image display systems are increasingly being used for presentation and consultation, in particular in the field. For this purpose, portable computers are used. However, these only have a permanently mounted flat screen.
Ein Flachbildschirm alleine erschwert die Präsentation, insbesondere für mehr als einen Zuschauer, da sich die Personen um den zumeist kleinen Bildschirm herum gruppieren müssen, wenn sie auf einem Bildschirm die Präsentation verfolgen müssen. Zusätzlich - -A flat screen alone complicates the presentation, especially for more than one spectator, as people have to group around the mostly small screen when they need to follow the presentation on a screen. additionally - -
ist es nicht möglich den Zuschauem eine begrenzte Anzahl von Daten (im Vergleich zur Ansicht des Präsentierenden) zur Ansicht zu zeigen.it is not possible to show viewers a limited amount of data (compared to the presenter's view).
Dieses Problem kann zur Zeit nur durch die Mitführung eines weiteren Bildschirms gelöst oder eines Projektions gerätes gelöst werden, welche dann für die Präsentation genutzt werden können und das Bild für die Zuseherschaft präsentiert . Hierdurch muss der Präsentierende jedoch ein weiteres Gerät mit sich fuhren. Zusätzlich bedürfen die meisten gängigen Flachbildschirme einer eigenen Energiezufuhr. Des Weiteren ist ein gewisses technisches Verständnis für den Aufbau and Betrieb notwendig.This problem can currently be solved only by the entrainment of another screen or a projection device to be solved, which can then be used for the presentation and presents the image for the public. However, the presenter has to carry another device with him. In addition, most commonly used flat screens require their own power supply. Furthermore, a certain technical understanding of the structure and operation is necessary.
Es ist daher die Aufgabe der vorliegenden Erfindung, eine Vorrichtung zu schaffen, die den gleichzeitigen Betrieb mehrere Flachbildschirme an einem tragbaren Computer ermöglicht, wobei alle Bildschirme fest, aber beweglich mit dem tragbaren Computer verbunden sind und über eine gemeinsame Energiequelle mit Energie versorgt werden. Die Bildschirme werden so angebracht, dass Personen die nicht nebeneinander sitzen, gleichzeitig die Bildwiedergabe auf einem der beiden Flachbildschirme beobachten können.It is therefore the object of the present invention to provide a device which allows the simultaneous operation of multiple flat screens on a portable computer, all screens being fixed but movably connected to the portable computer and powered by a common power source. The screens are positioned so that people who are not sitting side by side can simultaneously watch the image on one of the two flat screens.
Moderne Grafikkarten ermöglichen grundsätzlich den Anschluss von zwei oder mehr Monitoren. Diese zusätzlichen Anschlüsse können bei der vorliegenden Erfindung genutzt werden, um die zusätzlichen Monitore mit Bilddaten zu versorgen. Die Versorgung mit Energie kann über den in den mobilen Computereingebauten Akkumulator erfolgen.Modern graphics cards basically allow the connection of two or more monitors. These additional ports can be used in the present invention to provide the additional monitors with image data. The supply of energy can be done via the accumulator installed in the mobile computer.
Die Anordnung der Bildschirme soll auch ermöglichen, dass beide Bildschirme durch den Nutzer an der Tastatur gleichzeitig betrachtet und genutzt werden können. Hierzu soll die Verbindung der Bildschirme möglichst flexibel in ihren Bewegungsrichtungen sein.The arrangement of the screens should also allow both screens to be simultaneously viewed and used by the user on the keyboard. For this purpose, the connection of the screens should be as flexible as possible in their directions of movement.
Die Verbindung der Bildschirme soll ermöglichen, die zusätzlichen Bildschirme so einzuschwenken das sie mit der Sichtfläche auf der Rückseite des ersten Bildschirmes eingerastet werden kann. Dies ermöglicht einen optimalen Schutz der Bildschirme. Die genannte Verbindung kann an jeder der drei Seiten des ersten Bildschirmes erfolgen, an der dieser nicht an dem sonstigen Computergehäuse verbunden ist.The connection of the screens should enable the additional screens to be swiveled in so that they can be snapped into the visible area on the back of the first screen. This allows optimal protection of the screens. Said connection can be made on each of the three sides of the first screen, where it is not connected to the other computer housing.
Ein Beispiel ist in den Figuren 1 bis 4 gezeigt.. Die Verbindung der Bildschirm erfolgt seitlich.An example is shown in Figures 1 to 4. The connection of the screen is made laterally.
Die jeweilige Verbindung der Bildschirme ist ein Gelenk/Scharnier, welches dreidimensionale Bewegungen erlaubt. Dies ermöglicht das Schwenken des zweiten Bildschirmes sowohl in die vom Nutzer des Computers ab als auch zugewandte Seite. The respective connection of the screens is a joint / hinge, which allows three-dimensional movements. This allows the second screen to be swiveled both into and out of the user's side of the computer.
