Abstract
Spann- und Befestigungsvorrichtung, bestehend aus einer U-förmigen Klammer, in deren einem freien Schenkel ein Gewindeloch befindlich ist, in das eine Schraube eingeschraubt ist, die an dem zwischen den Schenkeln der U-förmigen Klammer liegenden Ende eine an dem zu spannenden Gegenstand anzulegende Scheibe angeordnet ist und die mit Mitteln zu ihrem Drehen versehen ist, dadurch gekennzeichnet, daß die Schraube eine Schloßschraube ist, deren zwischen den Schenkeln liegender Kopf die an dem zu spannenden Gegenstand anliegende Scheibe zum Spannen des zu spannenden Gegenstandes bildet.Clamping and fastening device, consisting of a U-shaped bracket, in one of the free legs of which there is a threaded hole into which a screw is screwed which, at the end between the legs of the U-shaped bracket, is to be applied to the object to be clamped Disc is arranged and which is provided with means for rotating it, characterized in that the screw is a lock screw whose head lying between the legs forms the disc resting against the object to be clamped for clamping the object to be clamped.
Description
Die Erfindung betrifft eine Spann- und Befestigungsvorrichtung, bestehend aus einer U-förmigen Klammer, in deren einem freien Schenkel ein Gewindeloch befindlich ist, in das eine Schraube eingeschraubt ist, die an dem zwischen den Schenkeln der U-förmigen Klammer liegenden Ende eine an dem zu spannenden Gegenstand anzulegende Scheibe angeordnet ist und die mit Mitteln zu ihrem Drehen versehen ist.The invention relates to a tensioning and fastening device, consisting of a U-shaped bracket, in which a free leg is a threaded hole befindlich, in which a screw is screwed, which at the lying between the legs of the U-shaped clip end to the is arranged to exciting object to be applied disc and which is provided with means for their rotation.
Solche Vorrichtungen sind jedem Handwerker und auch jedem Bastler bekannt. Bei den bekannten Vorrichtungen ist am einen, dem zwischen den Schenkeln liegenden Teil der Schraube, ein primitives Drehgelenk angeordnet, das der Scheibe erlaubt, ohne an der Drehung der Schraube teilzunehmen, drehfest an dem zu spannenden Gegenstand anzuliegen. Diese Konstruktion mit dem Drehgelenk verteuert die Herstellung. Am anderen, außerhalb der Schenkel liegenden Ende der Schraube, befindet sich ein Handgriff für die Drehung der Schraube. Dessen Anordnung wird oft als störend empfunden, auch sie verteuert die Herstellung dieser an sich primitiven, aber trotzdem sehr nützlichen Vorrichtung.Such devices are known to every craftsman and every hobbyist. In the known devices, on the one, the lying between the legs of the screw part, a primitive pivot arranged, which allows the disc, without participating in the rotation of the screw, rotatably abut the object to be clamped. This construction with the swivel makes the production more expensive. At the other, outside of the leg lying end of the screw, there is a handle for the rotation of the screw. Its arrangement is often perceived as disturbing, it too expensive the production of this in itself primitive, but still very useful device.
Die Erfindung vermeidet die aufgezeigten Nachteile und schafft eine äusserst einfach herstellbare und keineswegs geringer nützliche Spann- und Befestigungsvorrichtung.The invention avoids the disadvantages and provides a very easy to produce and by no means less useful clamping and fastening device.
Die Erfindung besteht darin, daß die Schraube dieser Spann- und Befestigungsvorrichtung eine in Massenproduktion hergestellte und daher äußerst billige Schloßschraube ist, deren zwischen den Schenkeln der U-förmigen Klammer liegender Kopf die an dem zu spannenden Gegenstand anliegende Scheibe zum Spannen des zu spannenden Gegenstandes bildet.The invention is that the screw of this clamping and fastening device is a mass-produced and therefore extremely cheap lock screw whose lying between the legs of the U-shaped bracket head forms the voltage applied to the object to be clamped disc for clamping the object to be clamped ,
Dadurch wird die Herstellung der Spann- und Befestigungsvorrichtung äußerst billig, es ist nur die Klammer aus einem Stück Flacheisen zu biegen und mit einem Gewindeloch zu versehen und dann die Schlosschraube aus der Massenproduktion in das Gewindeloch einzuschrauben. Die Nachteile des Drehgelenkes und seiner Montage auf der einen Seite der Schraube sowie der Fertigung und Montage des Handgriffes am anderen Ende der im Gewindeloch montierten Schraube sind entfallen.This makes the production of the clamping and fastening device extremely cheap, it is only the clip of a piece of flat iron to bend and provided with a threaded hole and then screw the Schlosschraube from mass production in the threaded hole. The disadvantages of the rotary joint and its mounting on one side of the screw and the manufacture and assembly of the handle at the other end of the screw mounted in the threaded hole are eliminated.
Um die Schraube drehen zu können, ist bei den in der Massenproduktion hergestellten Schloßschrauben unter dem Kopf der Schraube eine Angriffsfläche für ein Drehwerkzeug, einen Schraubenschlüssel, angeordnet.In order to rotate the screw, an attack surface for a turning tool, a wrench is arranged in the screws produced in mass production under the head of the screw.
Bei der erfindungsgemäßen Art einer Spann- und Befestigungsvorrichtung hat der Kopf der Schraube zweckmäßigerweise einen kreisförmigen Umfang und/oder ist Teil einer Kugelkalotte, so daß ein Drehgelenk enfallen kann.In the inventive type of clamping and fastening device of the head of the screw has expediently a circular circumference and / or is part of a spherical cap, so that a hinge can be omitted.
Bei dieser Spann- und Befestigungsvorrichtung ist zweckmäßigerweise die Länge des Schraubenschaftes so bemessen, daß der Schraubenschaft nicht oder nur geringfügig über die Außenfläche des ihn aufnehmenden Schenkels hinaussteht, was man durch einfaches Absägen oder Abflexen des aus der Vorrichtung herausstehenden Schraubenteiles erreichen kann.In this tensioning and fastening device, the length of the screw shank is expediently dimensioned such that the screw shank does not protrude slightly beyond the outer surface of the leg receiving it, which can be achieved by simply sawing off or flexing the screw part protruding from the device.
Anhand der anliegenden Zeichnung ist die Erfindung näher erläutert:Reference to the accompanying drawings, the invention is explained in more detail:
