Description

LupeMagnifying glass

Die Erfindung betrifft eine Lupe.The invention relates to a magnifying glass.

Fehlsichtige können sich bei Nichtverfugbarkeit ihrer Brille häufig durch Verwendung einer Lupe helfen. Derartige Lupen sind in vielfältiger Ausgestaltung bekannt, häufig sind jedoch auch diese im Ernstfall nicht auffindbar. If glasses are not available, people with poor eyesight can often help themselves by using a magnifying glass. Magnifying glasses of this kind are available in many different designs, but they are often impossible to find in an emergency.

Der Erfindung liegt die Aufgabe zugrunde, eine Lupe zu schaffen, die dem Verwender in solchen Fällen zuverlässig zur Verfügung steht.The invention is based on the object of creating a magnifying glass that is reliably available to the user in such cases.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die Lupe durch einen Teilbereich einer Karte, insbesondere Wertkarte (Scheckkarte, Kreditkarte, TelefonkarteAccording to the invention, this object is achieved in that the magnifying glass is guided through a portion of a card, in particular a prepaid card (cheque card, credit card, telephone card

oder dgl. aus Kunststoff) gebildet wird. Dabei ist die Lupe vorzugsweise als Fresnel-Linse ausgebildet.or similar made of plastic). The magnifying glass is preferably designed as a Fresnel lens.

Die Erfindung wird im folgenden anhand einer Zeichnung erläutert, deren einzige Figur eine mit einer Fresnel-Linse versehene Wertkarte zeigt.The invention is explained below with reference to a drawing, the only figure of which shows a value card equipped with a Fresnel lens.

Die Wertkarte 12 weist - in üblicher Weise - einen Magnetstreifen 14 auf. Ein Teil des weder von dem Magnetstreifen noch von der Unterschriftszone belegten Bereichs ist transparent ausgebildet und als Fresnel-Linse ausgebildet: Dieser Teilbereich 10 der Wertkarte 12 ist also in Ringzonen gleicher maximaler Dicke unterteilt, so daß ein stufenartiger Aufbau entsteht. Die Krümmungsradien der verschiedenen Ringzonen sind so gebildet, daß die Brennpunkte aller Zonen zusammenfallen, so daß ein optische Linse gebildet wird.The value card 12 has - in the usual way - a magnetic strip 14. A part of the area not occupied by the magnetic strip nor by the signature zone is transparent and designed as a Fresnel lens: This partial area 10 of the value card 12 is therefore divided into ring zones of the same maximum thickness, so that a step-like structure is created. The radii of curvature of the various ring zones are formed in such a way that the focal points of all zones coincide, so that an optical lens is formed.

Die Ausbildung der Lupe in einen Teilbereich einer Wertkarte hat den Vorteil, daß bei Verfügbarkeit dieser Wertkarte - auf deren Mitnahme der Verwender ja regelmäßig achtet - auch die Lupe zur Verfügung steht. Wer beispielsweise im Notfall in einem Telefonbuch eine Nummer sucht, hat bei Verfügbarkeit der Telefonkarte bei erfindungsgemäßer Ausbildung auch immer eine Lupe bei sich, die das Nachschlagen einer Telefonnummer ermöglicht.The design of the magnifying glass in a part of a prepaid card has the advantage that if this prepaid card is available - which the user regularly takes with him - the magnifying glass is also available. For example, if someone is looking for a number in a telephone book in an emergency, if the telephone card is available, they always have a magnifying glass with them, which enables them to look up a telephone number, if they are designed according to the invention.
