Description
Ausziehbarer Stativfuß Es ist bereits, insbesondere an Holzstativen, Klinkengesperre vorgeschlagen, bei denen eine Sperrklinke des einen Auszugsteils gegenüber von Rasten des anderen Auszugsteils drehbar gelagert ist. Bei diesen bekannten Klinkengesperren steht die Klinke unter Wirkung einer Feder und hat einen nach außen ragenden Griffknopf, so daß diese Einrichtung einerseits nicht das Eindringen von Staub verhindert und andererseits nur dann verwendbar ist, wenn nur ein Auszugsteil mit solchem Klinkengesperre versehen ist.Extendable tripod base It is already, especially on wooden tripods, Ratchet mechanism proposed in which a pawl of one pull-out part is rotatably mounted opposite the catches of the other pull-out part. With these well-known Ratchet locking is the pawl under the action of a spring and has one to the outside protruding handle knob, so that this device on the one hand does not prevent the penetration of Prevents dust and, on the other hand, can only be used if only one pull-out part is provided with such a ratchet lock.
Andererseits ist für ein mehrteiliges Auszugsrohr bereits eine im Rohrinnern angebrachte, in Löchern eingreifende Sperrvorrichtung vorgeschlagen. Hier sind die Sperrglieder Bogenstücke, die durch Gegenstoßen eines von unaen eingeführten Körpers aus den die Rast bildenden Löchern zu entfernen sind. Diese Einrichtung ist etwas verwickelt.On the other hand, there is already an im for a multi-part extension tube Proposed locking device mounted inside the tube, engaging in holes. Here the locking members are arched pieces that are introduced by pushing against one of the others Body are to be removed from the holes forming the detent. This facility is something involved.
Die Erfindung bezweckt, ein ' Klinkengesperre für Ausziehrohre von Stativen zu schaffen, das unter Vermeidung von Federn und Handauslösung möglichst gegen Verschmutzung geschützt, einfach im Aufbau und leicht zu handhaben ist. Dies wird gemäß der Erfindung dadurch erreicht, daß in dem erweiterten Kopf des jeweiligen Innenrohres ein eine frei bewegliche Klinke tragender Querstift angebracht und gegenüber der Klinke ein Schlitz vorgesehen ist, durch die die Klinke in die im Außenrohr angebrachten Rasten fallen kann. Diese Rasten bestehen z. B. in treppenartigen Absätzen des Außenrohres oder in Löchern eines Einlagestreifens.The aim of the invention is to provide a 'ratchet lock for pull-out tubes To create tripods, avoiding springs and manual release as much as possible protected against contamination, simple in construction and easy to handle. this is achieved according to the invention in that in the enlarged head of the respective Inner tube a freely movable pawl carrying cross pin attached and opposite the pawl a slot is provided through which the pawl into the in the outer tube attached catches can fall. These notches exist z. B. in stair-like paragraphs of the outer tube or in holes of an insert strip.
Die Zeichnung zeigt den Gegenstand der Erfindung an Ausführungsbeispielen, und zwar: Abb. i ein erstes Ausführungsbeispiel in einem senkrechten Längsschnitt, Abb. a einen um 9o° zu Abb. i gedrehten Längsschnitt, Abb. 3 die Klinke, Abb. q. den verstärkten Kopfteil des Innenrohres mit Schlitz und Klinke, Abb. 5 drei Ausziehrohre an einem Stativkopf unter Sichtbarmachung der in Sperrstellung befindlichen Klinken, Abb.6 einen Stativteil mit Sichtbarmachung einer gelösten Klinke, Abb. 7 ein zweites Ausführungsbeispiel im Längsschnitt, Abb. 8 den gelochten Einlegestreifen, Abb. 9 einen Querschnitt zu Abb. 7 in Höhe der Klinke und Abb. io eine dritte Ausführungsart mit gebogener Klinke.The drawing shows the subject matter of the invention in exemplary embodiments, namely: Fig. i a first embodiment in a vertical longitudinal section, Fig. A shows a longitudinal section rotated by 90 ° to Fig. I, Fig. 3 the latch, Fig. Q. the reinforced head part of the inner tube with slot and latch, Fig. 5 three extension tubes on a tripod head making the latches in the locked position visible, Fig. 6 shows a tripod part with a released pawl being made visible, Fig. 7 a second Embodiment in longitudinal section, Fig. 8 the perforated insert strips, Fig. 9 shows a cross-section to FIG. 7 at the level of the pawl and FIG. 10 shows a third embodiment with curved handle.
Beim ersten Ausführungsbeispiel (Abb. i bis 6) ist das Außenrohr a innen mit schrägen, stufenartigen Rasten d versehen. Der Kopf des Innenrohres b ist erweitert und mit einernAusschnitt (Abb. q.) versehen, durch den die in diesem Kopf an einem Querstift e gelagerte Klinke hindurchtreten kann. Stellt man das Stativ auf (Abb.5), so fällt die Klinke c durch ihr Eigengewicht in die ihr benachbarte Rast d. Für das Zusammenlegen führt man den betreffenden Stativfuß in die aus Abb. 6 ersichtliche Lage, so daß die Klinke c selbsttätig aus den Rasten d herausfällt.In the first embodiment (Fig. I to 6) the outer tube is a provided with inclined, step-like notches d on the inside. The head of the inner tube b is expanded and provided with a cutout (Fig. q.) through which the in this Head on a cross pin e mounted latch can pass. If you put the tripod on (Fig.5), the pawl c falls due to its own weight into the neighboring one Rest d. To fold the stand, guide it into the position shown in Fig. 6 visible position, so that the pawl c automatically falls out of the notches d.
Vom ersten Ausführungsbeispiel unterscheidet sich das Ausführungsbeispiel der Abb.7 bis 9 dadurch, daß die Rasten als Löcher f auf einem an der Innenwand des Außenrohrs befestigten Einlagestreifen ausgebildet sind.The embodiment differs from the first embodiment the Fig.7 to 9 in that the notches as holes f on one on the inner wall of the outer tube attached insert strips are formed.
Bei dem Ausführungsbeispiel der Abb. io ist die Sperrklinke im Winkel gebogen, um ein besseres Ein- und Ausklinken zu erreichen. Die Löcher h befinden sich in der Wand des Außenrohrs.In the embodiment of Fig. Io the pawl is at an angle curved to achieve better engagement and disengagement. The holes h are located in the wall of the outer tube.
