Description

Aus Schraube und Mutter bestehende Spannvorrichtung für die Aufreihgurte von Loseblätterbüchern. Die Erfindung betrifft eine iSpannvorrichtung für Loseblätterbücher derjenigen Art, bei der eine Schraube und Mutter für das Zusammenspannen vorgesehen sind. Insbesondere bezieht sich die Erfindung auf solche Loseblätterbücher, bei denen die Schraube in eine Mutter auf einer Querstange eingreift, die an Gurten oder ähnlichen biegsamen Teilen angebracht ist, die zwischen den Deckeln verlaufen und durch die Blätter hindurchtreten. Der Zweck der Erfindung besteht darin; eine verbesserte .Bauart für die Mutter zu schaffen.Tensioning device consisting of screw and nut for the straps of loose leaf books. The invention relates to a clamping device for loose leaf books the kind in which a screw and nut are provided for clamping together are. In particular, the invention relates to such loose leaf books which the screw engages in a nut on a crossbar that is attached to straps or similar flexible parts extending between the lids and step through the leaves. The purpose of the invention is; one improved design for the mother.

Demgemäß besteht das Wesen der Erfindung in der Ausbildung der Mutter aus einem Paar Metallblättern oder -streifen, die mit schrägliegenden Löchern versehen sind, in die das Schraubengewinde eingreifen kann: Auf der Zeichnung ist eine beispielsweise Ausführungsform der Erfindung veranschaulicht, und zwar zeigt: Abb. i eine Seitenansicht, Abb.2 eine Endansicht einer mit Mutter ausgebildeten Querstange, Abb. 3 einen Querschnitt durch die Mutter in vergrößertem Maßstabes Das dargestellte Ausführungsbeispiel zeigt ein Loseblätterbuch, das aus Aufreihgurten, Klemmbacken und Deckeln besteht. Die Gurte a sind hierbei -an einem Ende mit dem einen der Deckel verbunden und mit der Querstange b am anderen Ende. Die Querstange b ist mittels einer Schraube c im anderen Deckel verstellbar befestigt. Die Querstange besteht aus einem Paar Metallblättern, die gegeneinandergelegt sind und zwischen ihren Enden die Gurte festhalten. In der Mitte bildet jeder Teil eine querlaufende Ausbuchtung von halbkreisförmigem Querschnitt, um die Schraube halb zu umfassen, und es befinden sich in jedem Teil eine Anzahl schräg gestellter Löcher d, die sich von einer Seite der Platte zur anderen erstrecken. Wenn die Teile der Querstange zusammengefügt und beispielsweise mittels Nieten e verbunden sind, so. bilden die gefochten Teile der beiden Glieder eine Mutter; durch die hindurch die Schraube geführt werden kann, wobei die Gewindegänge in die Öffnungen d eingreifen.Accordingly, the essence of the invention is the training of the mother from a pair of metal sheets or strips with slanted holes into which the screw thread can engage: on the drawing, for example, is one Embodiment of the invention illustrated, namely shows: Fig. I a side view, Figure 2 is an end view of a crossbar formed with a nut, Figure 3 is a cross-section through the mother on an enlarged scale The illustrated embodiment shows a loose-leaf book consisting of straps, clamping jaws and covers. The straps a are connected at one end to one of the covers and with the crossbar b at the other end. The cross bar b is by means of a screw c adjustable in the other cover. The crossbar consists of a pair of metal sheets, which are placed against each other and hold the straps between their ends. In the In the middle, each part forms a transverse bulge with a semicircular cross-section, to half encompass the screw, and there are a number in each part slanted holes d extending from one side of the plate to the other stretch. When the parts of the crossbar are put together and for example connected by means of rivets e, so. form the fenced parts of the two limbs A mother; through which the screw can be passed, the threads engage in the openings d.

Es versteht sich, daß die Erfindung nicht nur auf das dargestellte Ausführungsbeispiel beschränkt ist, sondern auch für andere Spannvorrichtungen, bei der Schraube und Mutter zusammen wirken, gegebenenfalls mit kleinen baulichen Abänderungen benutzt werden kann.It goes without saying that the invention is not limited to what is shown Embodiment is limited, but also for other clamping devices, when the screw and nut work together, possibly with small structural ones Modifications can be used.
