Description
Vorrichtung zum gegenseitigen Festklemmen von ineinanderschiebbaren Rohren, insbesondere der Stockrohrteile von Gartenschirmen od. dgl. Die Erfindung geht aus von einer Vorrichtung zum gegenseitigen Festklemmen von ineinanderschiebbaren Rohren, insbesondere der Stockrohrteile von Gartenschirmen od. dgl., bestehend aus einem am äußeren Rohr drehbar gelagerten Exzenterhebel, der durch Einwirken auf das Innenrohr den für das Festklemmen erforderlichen Reibungsschluß erzeugt.Device for the mutual clamping of telescoping Pipes, in particular the stick pipe parts of garden umbrellas or the like. The invention is based on a device for mutual clamping of telescoping Pipes, in particular the stick pipe parts of garden umbrellas or the like, consisting of an eccentric lever rotatably mounted on the outer tube, which by acting on the inner tube generates the frictional engagement required for clamping.
Es ist fernerhin eine Vorrichtung zum gegenseiti-,gen Festklemmen von ineinanderschiebbaren Rohren, insbesondere der Stockrohrteile von Gartenschirmen od. dgl. bekanntgeworden, bei der zwischen einem die Verklemmung erzeugenden Exzenterhebel und dem Innenrohr ein elastisches Zwischenglied aus elastischem Stoff, z. B. Gummi, vorgesehen ist.It is also a device for mutual clamping of telescopic tubes, especially the stick tube parts of garden umbrellas Od. Like. Become known in which between an eccentric lever generating the jamming and the inner tube an elastic intermediate member made of elastic material, e.g. B. rubber, is provided.
Ferner ist eine Klemmverbindung für die lösbare Befestigung zweier ineinandergesteckter Körper unter Verwendung eines exzentrisch gelagerten Spannhebels bekanntgeworden, wobei eine die Verklem7 mung erzeugende Anpreßrolle mit einer der Krümmung der Außenfläche des zu verklenimenden Rohres entsprechend kombinierten Hohlkehle ausgestattet ist.Furthermore, there is a clamp connection for the detachable fastening of two nested body using an eccentrically mounted clamping lever become known, with a pressure roller generating the Verklem7 regulation with one of the Combined curvature of the outer surface of the tube to be cycled accordingly Is equipped with a fillet.
Die Aufgabe der Erfindung besteht demgegenüber darin, Vorrichtungen der im ersten Absatz dieser Beschreibung genannten Art insoweit zu verbessern, daß mit einfachen Mitteln eine federnde und doch feste Verklemmung, auch mit der Möglichkeit des Ausgleiches der Fertigungstoleranzen der an der Verklemmung teilnehmenden Teile, erreicht ist.In contrast, the object of the invention is to provide devices of the type mentioned in the first paragraph of this description to the extent that with simple means a resilient yet firm jamming, also with the possibility the compensation of the manufacturing tolerances of the parts participating in the jamming, is reached.
Bei einer ersten Aufgabenlösung ist bei der Erfindung vorgesehen, daß der Exzenterhebel im Bereich seines eigentlichen Klemmteiles mit mindestens einer Durchbrechung versehen ist.In a first solution to the problem, the invention provides that the eccentric lever in the area of its actual clamping part with at least is provided with an opening.
Bei einer zweiten Aufgabenlösung sind bei der Erfindung die größtenteils an sich bekannten Gestaltungsmerkmale vorgesehen, die darin bestehen, daß der aus elastischem Kunststoff bestehende Klemm- hebel an seiner Klenimkante mit einer der Krümmung der Rohraußenfläche entsprechenden Hohlkehle ausgestaltet ist.In a second solution to the problem, the invention provides for the most part known design features, which consist in the fact that the clamping lever made of elastic plastic is designed at its clamping edge with a groove corresponding to the curvature of the pipe outer surface.
Als für die Aufgabenlösungen vorteilhafte und förderliche Weiterbildungen sind weitere Gestaltungsmerkmale den am Schluß der Beschreibung angeführten Unteransprüchen 3 bis 6 zu entnehmen.Further design features can be found in subclaims 3 to 6 cited at the end of the description as further developments that are advantageous and conducive to solving the problem.
Durch die Erfindung wird so erreicht, daß mit einfachen Mitteln eine federnde und doch feste Verklemmung auch zum Ausgleich der Fertigungstoleranzen der an der Verklemmung teilnehmenden Teile ermöglicht ist. Bei der ersten Aufgabenlösung ist dadurch, daß Durchbrechungen vorgesehen sind, eine federnde Anklemmung und doch feste Verklemmung erreicht. Die Federung ergibt auch einen entspreehe . nden Toleranzausgleich. Bei der zweiten Aufgabenlösung ergibt das Zusammenwirken des elastischen Materials mit der Formgestaltung der Klemmkante die federnde und doch feste Verklemmung, wobei ebenfalls der Toleranzausgleich erreicht ist. Wenn bei dieser Ausführung noch die Gestaltungsmerkmale des Anspruches 2 hinzukommen, wird die Wirkung noch verstärkt.What is achieved by the invention is that a resilient yet firm clamping is made possible by simple means, also to compensate for the manufacturing tolerances of the parts participating in the clamping. In the first solution, the fact that openings are provided, a resilient clamping and yet firm clamping is achieved. The suspension also gives a corresponding . nd the tolerance compensation. In the case of the second solution to the problem, the interaction of the elastic material with the shape of the clamping edge results in the resilient yet firm clamping, with the tolerance compensation also being achieved. If the design features of claim 2 are added to this embodiment, the effect is further enhanced.
Die Erfindung wird an Hand mehrerer Ausführungsbeispiele in der Zeichnung näher erläutert. Hierbei zeigt F i g. 1 einen Schnitt durch die Verbindung eines der Ausführungsbeispiele, F i g. 2 einen Klemmhebel einer zweiten Ausführungsforin, F i g. 3 einen Klemmhebel einer dritten Ausführungsform und F i g. 4 einen Querschnitt durch eine weitere Ausführungsforin.The invention is explained in more detail on the basis of several exemplary embodiments in the drawing. Here, FIG. 1 shows a section through the connection of one of the exemplary embodiments, FIG. 2 a clamping lever of a second embodiment, FIG . 3 shows a clamping lever of a third embodiment and FIG . 4 shows a cross section through a further embodiment.
In der Zeichnung ist die Vorrichtung zum gegenseitigen Festklemmen von ineinanderschiebbaren Rohren 1, 2, insbesondere der Stockrohrteile von Gartenschirmen od. dgl., zu erkennen. Die Vorrichtung besteht aus einem am äußeren Rohr 1 drehbar gelagerten Exzenterhebel 3, der durch Einwirken auf das Innenrohr 2 den für das Festklemmen erforderlichen Reibungsschluß erzeugt.In the drawing, the device for the mutual clamping of tubes 1, 2 that can be pushed into one another, in particular the stick tube parts of garden umbrellas or the like, can be seen. The device consists of an eccentric lever 3 which is rotatably mounted on the outer tube 1 and which, by acting on the inner tube 2, generates the frictional engagement required for clamping.
Der Exzenterhebel 3 kann im Bereich seines eigentlichen Klemmteils 4 mit mindestens einer Durchbrechung 5, 6, 7 versehen sein. Der aus elastischem Kunststoff bestehende Exzenterhebel 9 kann an seiner Klemmkante 8 mit einer der Krümmung der Außenrohrfläche entsprechenden Hohlkehle 10 ausgestattet sein.The eccentric lever 3 can be provided with at least one opening 5, 6, 7 in the area of its actual clamping part 4. The eccentric lever 9 , which is made of elastic plastic, can be equipped on its clamping edge 8 with a groove 10 corresponding to the curvature of the outer tube surface.
Die Durchbrechung 5 kann eine schlitzartige, geschlossene Durchbrechung sein, die im wesentlichen parallel zur wirksamen Klemmkante verlaufend vorgesehen ist. Die Durchbrechung 6 -kann eine im wesentlichen parallel zur wirksamen Klemmkante verlaufende, schlitzartige, einseitig offene Durchbrechung sein.The opening 5 can be a slot-like, closed opening which is provided to run essentially parallel to the effective clamping edge. The opening 6 can be a slot-like opening which is open on one side and which runs essentially parallel to the effective clamping edge.
Die Durchbrechungen können mehrere nebeneinander angeordnete Bohrungen sein.The openings can have several holes arranged next to one another be.
Die Durchbrechung 7 kann derart gestaltet sein, daß der mit zwischen dem Schlitz und der wirksamen Randkante 11 verbleibende Stegteil 12 nach Art eines Trägers Bleicher Festigkeit in seinem Mittelteil etwas verbreitert ist.The opening 7 can be designed in such a way that the web part 12 remaining between the slot and the effective marginal edge 11 is somewhat widened in its central part in the manner of a carrier of bleaching strength.
