Fig. 3 zeigt eine schematische, perspektivische Darstellung des zweiten Klemmelements der Buchklemmvorrichtung. Das zweite Klemmelement 12 (Fig. 1) umfasst das Anpresselement 16 mit einer flexiblen Federplatte 18, die einen im wesentlichen konkaven, an den Kanten 28, 30 jedoch konvex gebogenen Querschnitt aufweist. Durch diese leicht konvex gebogenen Kanten werden Druckstellen oder sonstige Beschädigungen des Buchs 20 während des Klemmvorgangs vermieden. Die Federplatte 18 kann mittels Befestigungsmitteln 32, z. B. Nieten oder Schrauben, vorzugsweise versenkten oder eingelassenen Schrauben, am Anpresselement 16 befestigt sein.Fig. 3 shows a schematic, perspective view of the second clamping element of the Book clamp. The second clamping element 12 (FIG. 1) comprises the pressing element 16 with a flexible spring plate 18, which is a substantially concave, on the edges 28, 30, however, has a convexly curved cross section. Through this slightly convex bent edges become pressure marks or other damage to the book 20 avoided during the clamping process. The spring plate 18 can by means Fasteners 32, e.g. B. rivets or screws, preferably countersunk or recessed screws, attached to the pressure element 16.

Gemäß einer in Fig. 4 gezeigten weiteren Ausführungsform der Erfindung kann die flexible Federplatte 18 auch einen anderen, beispielsweise vieleckigen, Querschnitt aufweisen. Wie in Fig. 4 gezeigt ist, umfasst die Federplatte 18 mit vieleckigem Querschnitt eine Vielzahl von geraden Abschnitten, die als Abschnitte C, D, E, F und G dargestellt sind. Dabei ist jedoch wichtig, dass die verschiedenen Abschnitte des Vielecks so miteinander verbunden sind, dass sie eine flexible Federplatte 18 bilden, die konkav am Anpresselement 16 befestigt werden kann.According to a further embodiment of the invention shown in FIG. 4, the flexible Spring plate 18 also have a different, for example polygonal, cross section. How 4, the spring plate 18 having a polygonal cross section comprises a plurality of straight sections shown as sections C, D, E, F and G. It is however, it is important that the different sections of the polygon are so interconnected are that they form a flexible spring plate 18 which is concavely attached to the pressing element 16 can be.

In Fig. 5 ist eine weitere Ausführungsform der vorliegenden Erfindung gezeigt. Die in den bisher beschriebenen Ausführungsformen vorgesehenen Federplatten sind im allgemeinen mittels vorzugsweise in der Mitte der Federplatte angeordneten Befestigungsmitteln 32, beispielsweise Nieten oder Schrauben, am Anpresselement 16 befestigt. Unter bestimmten, ungünstigen Bedingungen besteht jedoch weiterhin die Möglichkeit, dass diese Befestigungsmittel das Buch kontaktieren und unerwünschte Druckstellen auf dem Papier bilden. Es ist daher vorteilhaft, die Federplatte an der Kante des Anpresselements zu befestigen, damit die Befestigungsmittel 32 das Papier nicht kontaktieren. Da jedoch auch eine ausreichende Klemmkraft erzeugt werden muss, ist es vorteilhaft, wenn die Klemmplatte während des Anpressvorgangs das Buch in zwei Linien kontaktiert. Dazu sind, wie in Fig. 5 gezeigt ist, an einer Kante 42 des Anpresselements 16 eine erste und eine zweite Federplatte 34, 36 befestigt. Beide Federplatten sind mittels einer Vielzahl von Befestigungsmitteln 32, z. B. Nieten oder eingelassenen Schrauben, am Anpresselement 16 befestigt.

The in the The previously described embodiments of the spring plates are generally by means of fastening means 32 preferably arranged in the middle of the spring plate, for example rivets or screws, attached to the pressing element 16. Under certain unfavorable conditions, however, there is still the possibility that this Fasteners contact the book and unwanted pressure marks on the paper form. It is therefore advantageous to close the spring plate on the edge of the pressing element secure so that the fasteners 32 do not contact the paper. But there too a sufficient clamping force must be generated, it is advantageous if the Clamping plate contacted the book in two lines during the pressing process. To do this, As shown in FIG. 5, a first and a one on an edge 42 of the pressing element 16 second spring plate 34, 36 attached. Both spring plates are made using a variety of Fasteners 32, e.g. B. rivets or recessed screws on the pressure element 16 attached. Both spring plates 34, 36 are closed along the straight line from edge point 38 Edge point 40 bent.

Wie in Fig. 6 gezeigt ist, ist die erste Federplatte 34 derart am Anpresselement 16 befestigt, dass zwischen der Oberfläche 13 des Anpresselements 16 und der ersten Federplatte 34 ein Winkel α gebildet ist. Die zweite Federplatte 36 ist am Anpresselement 16 derart befestigt, dass die Oberfläche 13 des Anpresselements 16 und die Federplatte 36 einen Winkel β bilden, der größer ist als der Winkel α. Der Winkel α ist kleiner als 45°, vorzugsweise kleiner als 30°, und liegt insbesondere zwischen 1° und 10°. Der Winkel β ist kleiner als 60°, vorzugsweise kleiner als 40° und liegt insbesondere zwischen 2° und 15°.As shown in FIG. 6, the first spring plate 34 is fastened to the pressing element 16 in such a way that that between the surface 13 of the pressing element 16 and the first spring plate 34 Angle α is formed. The second spring plate 36 is fastened to the pressing element 16 in such a way that that the surface 13 of the pressing element 16 and the spring plate 36 form an angle β form, which is greater than the angle α. The angle α is less than 45 °, preferably less than 30 °, and is in particular between 1 ° and 10 °. The angle β is less than 60 °, preferably less than 40 ° and is in particular between 2 ° and 15 °.

Wenn ein Buch 20 gegen das die beiden Federplatten 34 und 36 umfassende Anpresselement 16 gedrückt wird, kontaktiert es die beiden Federplatten 34, 36 in den Berührpunkten H, I, wie in der Querschnittsansicht in Fig. 6 gezeigt ist. Mit dieser Ausführungsform der Erfindung ist es möglich, einen Kontaktieren der zu klemmenden Bücher durch die Klemmelemente 10, 12 entlang zweier Linien zu erzielen und damit die erforderliche Anpresskraft zu erreichen.If a book 20 against the two spring plates 34 and 36 comprising Pressing element 16 is pressed, it contacts the two spring plates 34, 36 in the Touch points H, I as shown in the cross-sectional view in FIG. 6. With this Embodiment of the invention, it is possible to contact the to be clamped To achieve books by the clamping elements 10, 12 along two lines and thus the to achieve the required contact pressure.
