Die Erfindung geht aus von einer Klemmsperre bei Teleskoprohrverbindungen, insbesondere für ausziehbare Stativbeine, für Photo- und Kinostative oder auch für Projektionstische, unter Verwendung einer Klemmhülse, die zwischen den Teleskoprohren drehbar und durch Formschluß über Nocken an einem der beiden Teleskoprohre an diesem Teleskoprohr in Längsrichtung lagegesichert angeordnet ist, wobei durch Verdrehung der Teleskoprohre gegeneinander eine Sperrung erreicht wird.The invention is based on a clamping lock in telescopic pipe connections, in particular for Extendable tripod legs, for photo and cinema tripods or also for projection tables, using a clamping sleeve, which can be rotated between the telescopic tubes and is attached by means of a form fit via cams one of the two telescopic tubes is arranged in a secured position on this telescopic tube in the longitudinal direction, locking is achieved by rotating the telescopic tubes against each other.
Die bei der Erfindung demgegenüber noch zu lösende Aufgabe besteht darin, Klemmsperren der genannten Art insoweit zu verbessern, daß nicht nur eine kraftschlüssige Klemmverbindung zwischen den zu verbindenden Teilen erreicht ist, sondern auch eine formschlüssige und damit eine bessere und wirksamere und von Reibungsverhältnissen unabhängige Verbindung ermöglicht ist.In contrast, the problem to be solved in the case of the invention is to provide the clamping locks to improve mentioned type so far that not only a non-positive clamping connection between the parts to be connected is achieved, but also a form-fitting and thus a better and more effective and friction-independent connection is enabled.
Zur Lösung dieser Aufgabe ist bei der Erfindung vorgesehen, daß die Lagesicherung der Klemmhülse in Längsrichtung dadurch erreicht ist, daß an einem Ende der Klemmhülse in Umfangsrichtung mehrere tangential nach außen verlaufende, federnde Zungen aus der Klemmhülsenwand ausgeschnitten vorgesehen sind und die Ausschnitte, die breiter sind als die Zungen, in die in Umfangsrichtung der Wand an dem Ende des anderen Teleskoprohres vorgesehenen Nocken eingreifen und daß außerdem zwischen der Klemmhülse und dem anderen Teleskoprohr in der Auszugsstellung ein Formschluß dadurch erreichbar ist, daß am anderen Ende der Klemmhülse Aussparungen vorgesehen sind, in die entsprechend geformte Ausbuchtungen in der Wand des anderen Teleskoprohres formschlüssig eingreifen, wobei außerdem zwischen dem einen Teleskoprohr und der Klemmhülse ein Kraftschluß dadurch erreichbar ist, daß die Zungen mit den mit in Drehrichtung zunehmender Stärke ausgebildeten Nocken in Klemmwirkung bringbar sind, wobei das andere Teleskoprohr am Ende konisch geformt ist.To solve this problem, the invention provides that the position of the clamping sleeve is secured is achieved in the longitudinal direction that at one end of the clamping sleeve in the circumferential direction several resilient tongues extending tangentially outward are provided cut out of the clamping sleeve wall are and the cutouts, which are wider than the tongues, in the circumferential direction of the wall engage the end of the other telescopic tube provided cam and that also between the Clamping sleeve and the other telescopic tube in the extended position a form fit can be achieved is that at the other end of the clamping sleeve recesses are provided in the correspondingly shaped Bulges in the wall of the other telescopic tube engage positively, with In addition, a frictional connection can be achieved between the one telescopic tube and the clamping sleeve, that the tongues with the cams formed with increasing strength in the direction of rotation have a clamping effect can be brought, the other telescopic tube is conically shaped at the end.
Bei dieser Aufgabenlösung sind folgende an sich bekannten Gestaltungsmerkmale benutzt:The following design features, known per se, are used to solve this problem:
Es ist bei einer Klemmvorrichtung für Teleskoprohre bekanntgeworden, ein klemmhülsenartiges Teil so auszubilden, daß Klemmteile an zwei verschiedenen Stellen in Längsrichtung der Rohre eine Klemmwirkung ermöglichen.It has become known in a clamping device for telescopic tubes, a clamping sleeve-like part to train that clamping parts at two different points in the longitudinal direction of the tubes Enable clamping effect.

Schnittflächen der geteilten Hülse dadurch zu ermöglichen, daß diese schrägen Schnittflächen aneinander gleiten, damit den Auöendurchmesser der Hülsenwand vergrößern, so daß sie an der Innenwand des Außenrohres klemmend anliegt.To enable cut surfaces of the split sleeve that these inclined cut surfaces against each other slide so that the outer diameter of the sleeve wall increases so that it is against the inner wall of the outer tube is jammed.
Es ist bei einer Rohrverbindung bekanntgeworden, zwei miteinander zu verbindende Teile mit sägczahnartigen Zungen ineinandergreifen zu lassen.It has become known in a pipe connection to have two parts to be connected with one another with sawtooth-like To let tongues interlock.
Durch die Erfindung wird auf einfache Weise erreicht, daß nicht nur eine kraftschlüssige Verbindung zwischen den zu verbindenden Teilen entsteht, sondern auch eine formschlüssige und dabei eine bessere und wirksamere und von den Reibungsverhältnissen unabhängige Verbindung ermöglicht ist. Hierbei ergeben auch die ausgeprägten Klemmstellen an den Enden der Klemmhülse eine Verklemmung auf einer größeren Länge und somit werden Wackelerscheinungen mit Sicherheit ausgeschlossen. Dies wird bei der Erfindung durch die besondere Ausgestaltungsart der Klemmhülsenenden und die am einen Teleskoprohr vorgesehenen Nocken, die mit entsprechenden Zungen an der Klemmhülse zusammenwirken, und den Formschluß durch entsprechende Ausbildungen am anderen Ende der Klemmhülse, die mit Ausbuchtungen der Wand des anderen Teleskoprohres zusammenwirken, erreicht. Bei der Klemmsicherung wird zunächst der Formschluß zwischen den Ausbuchtungen in der Wand des einen Teleskoprohres und den Aussparungen in der Klemmhülse in der Ausgangsstellung dadurch erreicht, daß durch kurzes Ineinanderstoßen die entsprechenden Teile ineinandergreifen, wonach durch Verdrehen der Formschluß zwischen den Nocken und den Zungen ermöglicht wird.The invention achieves in a simple manner that not only a non-positive connection between the parts to be connected, but also a form-fitting and better one and a more effective connection that is independent of the friction conditions is enabled. Here the pronounced clamping points at the ends of the clamping sleeve also result in jamming a greater length and thus wobbling phenomena are definitely excluded. this is in the invention by the special design of the clamping sleeve ends and the on a telescopic tube provided cams which interact with corresponding tongues on the clamping sleeve, and the form fit through corresponding formations at the other end of the clamping sleeve, which with bulges in the wall of the other telescopic tube cooperate achieved. In the case of clamping, the form fit is the first step between the bulges in the wall of a telescopic tube and the recesses in the clamping sleeve in the starting position is achieved by briefly pushing the corresponding Parts interlock, after which the positive locking between the cams by twisting and the tongues is made possible.
