Description
Schutzstreifenbefestigung für Karteikarten, bei der die Karten mit Längsrillen versehen sind, die mit entsprechenden Längsrillen des Schutzstreifens zusammen arbeiten Die Erfindung bezieht sich auf eine Schutzstreifenbefestigung für Karteikarten, bei der die Karten mit Längsrillen versehen sind, die mit entsprechenden Längsrillen des Schutzstreifens zusammen arbeiten, Bei den bekannten Einrichtungen sind beide Schenkel des Falzes wie auch die Karte mit einer durchlaufenden Längsrille versehen. Diese Anordnung bedeutet eine geschwächte Stellung am Rande der Karte, die leicht zum Umknicken des Randes führt. Zugleich ist so das Einführen der Karte in den Schutzfalz erschwert, weil die Karte entweder an dem Rande Widerstand findet oder den Schutzfalz spreizt, so daß er seinen Halt verliert. Dieser Nachteil wird der 1-Erfindung gemäß dadurch vermieden, daß der Falz nur auf einer Seite Rillen aufweist, so daß in den Falz auf der anderen Seite Karten eingesteckt werden können.Protective strip fastening for index cards, in which the cards with Longitudinal grooves are provided with corresponding longitudinal grooves of the protective strip Working Together The invention relates to a protective tab attachment for index cards in which the cards are provided with longitudinal grooves with corresponding Longitudinal grooves of the protective strip work together in the known devices Both legs of the fold as well as the card are with a continuous longitudinal groove Mistake. This arrangement means a weakened position on the edge of the map, which easily leads to the edge buckling. At the same time, this is how the card is inserted in the protective fold, because the card either finds resistance at the edge or spreads the protective fold so that it loses its hold. This disadvantage will the 1-invention according to avoided in that the fold only on one side grooves so that cards can be inserted into the fold on the other side.
Ein Ausführungsbeispiel der Anordnung gemäß der Erfindung ist in der Zeichnung veranschaulicht.An embodiment of the arrangement according to the invention is shown in FIG Drawing illustrates.
Die harte ist mit ii, der als Falte ausgebildete Schutzstreifen mit ia bezeichnet, der eine Schenkel der Falte des Randstreifens mit 13, der zweite mit 14. Die Längsrillen der Karte sind mit 2o, 2r bezeichnet. Sie greifen in entsprechende Längsrillen 22, 23 des Schutzstreifens. Auf diese Weise ist es möglich, in den Falz der anderen Seite Karten einzustecken. Durch die Befestigungsanordnung gemäß der Erfindung wird mit einfachen Mitteln ein sicherer Sitz des Randstreifens auf der Karte gewährleistet. Im besonderen ist diese Befestigungsanordnung wertvoll für Randstreifen, die aus festem, zähem, vorzugsweise nur in der Wärme plastisch werdendem Material, wie z. B. Zellhorn, gebildet sind, bei denen auch die Schenkel des Randstreifens sich federnd, indem sie mit Vorspannung ausgeführt werden, an die Kartenflächen anlegen können.The hard one is marked with ii, the protective strip designed as a fold with ia denotes one leg of the fold of the edge strip with 13, the second with 14. The longitudinal grooves of the card are denoted by 2o, 2r. They intervene in the appropriate Longitudinal grooves 22, 23 of the protective strip. In this way it is possible in the fold to insert cards on the other side. By the fastening arrangement according to Invention is a secure fit of the edge strip on the simple means Card guaranteed. In particular, this mounting arrangement is valuable for Edge strips made of firm, tough, preferably only plasticized in the heat Material such as B. cell horn, are formed, in which the legs of the edge strip resiliently, in that they are carried out with pre-tension, on the card surfaces can create.
