Description
Stativ. Es sind bereits Stative bekannt, deren massive Kopfplatte mit seitlichen Einschnitten versehen ist, in denen die Stativbeine nach oben und unten geschwenkt werden können.Tripod. There are already tripods known whose massive head plate is provided with side incisions, in which the tripod legs up and can be swiveled down.
Bei diesen Stativen -ist neben de Einschnitt für die Gelenkführung ein zweiter parallel geführter Einschnitt angebracht, um in der massiven, starren Kopfplatte einen federnden Steg zu bilden, der die Möglichkeit gibt, das Stativbeinende 'in der Gelenkführung schließend anschrauben zu können.With these tripods there is next to the incision for the joint guide a second parallel incision attached to the massive, rigid Head plate to form a resilient web, which gives the possibility of the tripod leg end '' to be able to screw on in the joint guide.
Die Erfindung bezweckt, diese Doppelschätze zu vermeiden und doch eine einwandfreie Gelenkführung zu erhalten.The invention aims to avoid these double treasures and yet to get a perfect joint guidance.
Dies wird gemäß der Erfindung dadurch erreicht, daß die zum Einführen der einzelnen Schraube dienende Bohrung bis zu dem das Stativbeinende aufnehmenden Einschnitt in gleichbleibendem Querschnitt durchgeführt und daß als Gegenlager für die Schraube eine mittels Feder und Nut geführte Buchse in die Bohrung eingewitzt ist.This is achieved according to the invention in that the for insertion the individual screw serving hole up to the receiving end of the tripod leg Incision carried out in a constant cross-section and that as a counter bearing for the screw carved a bushing guided by a tongue and groove into the bore is.
Die Zeichnung zeigt ein Ausführungsbeispiel des Erfindungsgegenstandes, und zwar Abb. i eine teilweise geschnittene Draufsicht und Abb. a eine Seitenansicht des Stativkopfes. In der Stativkopfplatte i sind, wie insbesondere aus Abb. i ersichtlich ist, drei radiale Schlitze z vorgesehen, die zur Aufnahme der oben abgeflachten, Enden 3 der Stativbeine ¢ dienen. Die Befestigung der Stativbeine erfolgt in bekannter Weise durch Schrauben 5, die gleichzeitig als Drehzapfen dienen. Erfindungsgemäß liegt nun um den Schaft der Schrauben 5 herum je ein Führungsring 6, der mit einer Längsrippe 7 versehen ist. Letztere arbeitet mit einer in der Bohrung 9 zur Aufnahme der Schraube 5 vorgesehenen Längsnut 8 zusammen. An Stelle der Rippe 7 kann die Hülse 6 außen auch eine Längsnut aufweisen. 'Dann ist in der Bohrung 9 eine entsprechende Rippe anzubringen. Die Platte i ist mit einem Gewindebo1zen versehesi, der in bekannter Weise zwei verschiedene Gewinde r o und i i an gegenüberliegenden Flächen der Platte i trägt, so *daß Vorrichtungen mit verschiedenen Aufschraubgewiciden auf das Stativ aufgeschraubt werden können. Die Platte i kann dreieckig: oder jede andere gewünschte Gestalt. haben.The drawing shows an embodiment of the subject matter of the invention, namely Fig. i is a partially sectioned plan view and Fig. a is a side view of the tripod head. In the tripod head plate i, as can be seen in particular from Fig is, three radial slots z are provided to accommodate the flattened top, Ends 3 of the tripod legs ¢ are used. The tripod legs are attached in a known manner Way by screws 5, which also serve as pivot pins. According to the invention is now around the shaft of the screws 5 around each a guide ring 6, which with a Longitudinal rib 7 is provided. The latter works with one in the bore 9 for recording the screw 5 provided longitudinal groove 8 together. Instead of the rib 7, the Sleeve 6 also have a longitudinal groove on the outside. 'Then there is a corresponding one in the bore 9 To attach rib. The plate i is provided with a threaded bolt, which is known in Way two different threads r o and i i on opposite surfaces of the plate i carries so * that devices with different screw-on weights on the tripod can be screwed on. The plate i can be triangular: or any other desired Shape. to have.
Zum Anbringen der Stativbeine 4 an der Platte i setzt man zunächst den Führungsring 6 in die Bohrung c9 ein, steckt dann die Schraube 5 durch den abgeflachten Teil 3 des Beines 4. hindurch und schraubt sie in das Gewinde der Platte ein. Die so befestigte Schraube 5 erhält durch den Ring 6 eine gute Führung und wird gleichzeitig durch diesen Ring gegen unbeabsichtigtes Lösen gesichert.To attach the tripod legs 4 to the plate i, one sets first insert the guide ring 6 into the bore c9, then insert the screw 5 through the flattened one Part 3 of the leg 4. through it and screw it into the thread of the plate. the screw 5 fastened in this way receives good guidance through the ring 6 and is at the same time secured against unintentional loosening by this ring.
