Flexible Tastatur mit modularem ^Flexible keyboard with modular ^

Datenverarbeitungsgeräte. . :. ■.Data processing equipment. . :. ■.

Für die Dateneingabe an Datenverarbeitungsgeräten wird im allgemeinen eine Tastatur verwendet, die hinsichtlich der Tastenfqrm und -anordnung einer Schreibmaschine'ntastatur vergleichbar ist. ■Diese ist gekennzeichnet durch Einzeltästen, die einen ■ ■■ For data entry on data processing devices, a keyboard is generally used which is comparable to a typewriter keyboard in terms of key shape and arrangement. ■This is characterized by individual keys which have a ■ ■■

Bekannt sind ebenfalls Tastaturen, die eine geschlossene Oberfläche aufweisen und ohne-Einzeltasten arbeiten, sogenannte Folientastaturen (z.B. GM 7434187). Sämtliche &eacgr; Tastaturen besitzen jedoch ein festes Gehäuse oder zumindest eine starre Bodenplatte.Keyboards that have a closed surface and work without individual keys are also known, so-called membrane keyboards (e.g. GM 7434187). However, all &eacgr; keyboards have a solid housing or at least a rigid base plate.

Gebrauchsmusteranmeldung "Flexible FdWntastaWfmtfmodulerem·Aufbau".' *..'26.10.1993Utility model application "Flexible FdWntastaWfmtfmodulerem·Aufbau".' *..'26.10.1993

Diese herkömmlichen Tastaturen bieten die folgenden Nachteile:These conventional keyboards have the following disadvantages:

a. Beim Transport, insbesondere bei der Anwendung tragbarer Kleincomputer (Notebooks), nimmt die Tastatur im Verhältnis zu den übrigen Funktionseinheiten des Rechners sehr viel Platz in Anspruch und sind relativ schwer.a. When transporting, especially when using small portable computers (notebooks), the keyboard takes up a lot of space in relation to the other functional units of the computer and is relatively heavy.

b. Die Tastatur ist in sich starr und somit unhandlich beim Transportieren, Verschieben und beim Verstauen.b. The keyboard is rigid and therefore difficult to transport, move or store.

c. Bei Folientastaturen wird die Kontaktsicherheit meistens durch über dem Kontakt domartig ausgeformte Designfolientasten gewährleistet. Diese bieten dem Fingerdruck meist erheblichen Widerstand und verhindern so eine angenehme und schnelle Bedienung der Tastatur.c. In membrane keyboards, contact reliability is usually ensured by dome-shaped design membrane keys above the contact. These usually offer considerable resistance to finger pressure and thus prevent the keyboard from being operated comfortably and quickly.

d. Die Höhe der Tastatur ist ergonomisch ungünstig für die Handhaltung, wenn keine Auflageflächen für die Handballen geschaffen werden.d. The height of the keyboard is ergonomically unfavourable for the hand position if no support surfaces are created for the palms of the hands.

e. Die Tastatur behindert durch ihre Bauhöhe am Arbeitsplatz die Arbeit mit anderen Arbeitsmitteln.e. The keyboard’s height at the workstation hinders working with other work equipment.

f. Sie sind gegen unbeabsichtigte Tastenauslösung, die bei manchen Anwenderprogrammen unkontrollierbare Folgen bis hin zum Datenverlust haben kann, nicht geschützt.f. They are not protected against unintentional key activation, which in some application programs can have uncontrollable consequences, including data loss.

g. Bei transportablen Tastaturen für Notebook-Computer wird oft aus Gründen der Platzersparnis ein gegenüber der DIN 2137 verändertes Layout mit wesentlich geringeren Tastenabständen und kleineren Tasten verwendet. Der Bedienungskomfort leidet hierbei besonders stark.g. For portable keyboards for notebook computers, a layout that is different from DIN 2137 with significantly smaller key spacing and smaller keys is often used to save space. This has a particularly negative impact on ease of use.

h. Die Tastatur ist unter wirtschaftlichen Gesichtspunkten nur begrenzt designfähig, da die Oberseite im Normalfall aus ca. 100 einzelnen Tasten besteht und diese nur unter großem Aufwand in ein einheitliches Design einbezogen werden können.h. From an economic point of view, the keyboard can only be designed to a limited extent, since the top normally consists of around 100 individual keys and these can only be incorporated into a uniform design with great effort.

Das Gebrauchsmuster beschreibt eine Tastatur, die extrem flach aufgebaut und im Gebrauchszustand flexibel ist. Die Tastatur vereint eine gegenüber herkömmlichen Tastaturen verbesserte Mobilität durch geringes Gewicht und Biegsamkeit mit der Möglichkeit, trotzdem eine vollständige Tastatur mit gängigem Layout und normalen DIN-Norm-Tastenabständen verwenden zu können.The utility model describes a keyboard that is extremely flat and flexible when in use. The keyboard combines improved mobility compared to conventional keyboards through low weight and flexibility with the possibility of still being able to use a full keyboard with a common layout and normal DIN standard key spacing.

Der flache Aufbau ermöglicht das Verbleiben der Tastatur auf dem Schreibtisch, auch wenn im Bereich der Tastatur andere Arbeiten ausgeführt werden sollen. Um dabei die versehentliche Auslösung von Tasten zu verhindern, kann die Tastatur über eine spezielle Tastenkombination abgeschaltet werden.The flat design allows the keyboard to remain on the desk, even if other work is to be carried out in the keyboard area. To prevent keys from being accidentally pressed, the keyboard can be switched off using a special key combination.

Die Tastatur ist modular aufgebaut (Abb. 2). Die eigentliche Tastatur kann mit Hilfe der festen Randteile (Abb. 1 und 2, Nr. 1), die entsprechend ausgeformt sind, formschlüssig auf verschiedenen Sockeln befestigt werden. Es sind mindestens zwei verschiedene Sockel als Zubehör vorgesehen.The keyboard has a modular design (Fig. 2). The actual keyboard can be attached to various bases using the fixed edge parts (Fig. 1 and 2, No. 1), which are shaped accordingly. At least two different bases are provided as accessories.

Der eine besteht aus einer einfachen, ebenen und dünnen aber dabei starren Platte, die als Unterlage im Falle unebener Arbeitsflächen mobil eingesetzt werden kann (Abb. 2, Nr. 5). Der zweite ist ein größerer, fester Sockel, in den die Tastatur zusammen mit der zuvor beschriebenen Platte eingelegt wird. Dieser zweite Sockel ist für den stationären Einsatz auf einem Schreibtisch vorgesehen (Abb. 2, Nr. 6).One consists of a simple, flat and thin but rigid plate that can be used as a mobile base in the case of uneven work surfaces (Fig. 2, No. 5). The second is a larger, fixed base into which the keyboard is placed together with the plate described above. This second base is intended for stationary use on a desk (Fig. 2, No. 6).

Die elektronische Controller-Einheit (Abb. 2., Nr. 3) mit dem Leitungsanschluß (Abb. 2, Nr. 8) ist als flache Funktionseinheit an der Seite der Tastatur innerhalb des Randteils (Abb. 1 und 2, Nr. 1) angebracht.The electronic controller unit (Fig. 2, No. 3) with the cable connection (Fig. 2, No. 8) is mounted as a flat functional unit on the side of the keyboard within the edge part (Fig. 1 and 2, No. 1).

Die Tastatur kann aufgrund ihres geringen Gewichtes, ihrer Flexibilität und ihrer geringen Bauhöhe sehr platzsparend und einfach transportiert werden.Due to its low weight, flexibility and low height, the keyboard can be transported very easily and takes up very little space.

Zum Transport läßt sich die Tastatur durch einen leicht lösbaren Steckkontakt an einer Seite der Tastatur von der Leitung zum Datenverarbeitungsgerät trennen (Abb. 1 und 2, Nr. 8).For transport, the keyboard can be separated from the cable to the data processing device by an easily removable plug contact on one side of the keyboard (Fig. 1 and 2, No. 8).

Ein Teil der Tastaturoberfläche kann aufgrund seiner glatten Oberflächenbeschaffenheit auch als Mauspad zur Bedienung des Computers mit Hife einer Maus verwendet werden (Abb. 2, Nr 2).Due to its smooth surface, part of the keyboard surface can also be used as a mouse pad for operating the computer with the help of a mouse (Fig. 2, No. 2).

Die extrem flache Bauweise ermöglicht ohne zusätzlichen konstruktiven Aufwand eine ergonomisch günstige Handhaltung bei der Bedienung, da die Handflächen locker vor der Tastatur aufgelegt werden können. Die Hände müssen nicht angehoben werden, um die Tasten zu erreichen.The extremely flat design enables an ergonomically favorable hand position when operating the device without any additional design effort, as the palms of the hands can be placed loosely in front of the keyboard. The hands do not have to be raised to reach the keys.

Zwischen der oberen Tastenfolie und dem Kontaktfoliensystem ist eine Pufferfolie (Abb. 1, Nr. 3) angeordnet, die den Fingerdruck, der auf die Tastenfolie ausgeübt wird, auf das Kontaktfoliensystem überträgt. Der für die Auslösung der Tasten erforderliche Fingerdruck ist dadurch gering und es wird eine kontaktsichere, schnelle, leise und angenehme Bedienung der Tastatur ermöglicht.A buffer foil (Fig. 1, No. 3) is arranged between the upper key foil and the contact foil system, which transfers the finger pressure exerted on the key foil to the contact foil system. The finger pressure required to activate the keys is therefore low and enables contact-safe, fast, quiet and comfortable operation of the keyboard.

Die Oberfläche der Tastatur und die übrigen Module können gestalterisch auf die Bedürfnisse des Anwenders abgestimmt werden.The surface of the keyboard and the other modules can be designed to suit the needs of the user.
