Description
Die Erfindung betrifft einen Auszug für Metallrohrenstative.The invention relates to an extension for metal tube stands.
Im Gegensatz zu bekannten Konstruktionen mit gleichfalls zylindrisch dicht auf-S einander lagernden Rohren, bei denen Federnasenanzahl des Innenrohres und Lochanzahl des Überrohres gleich sind, so daß jede Federnase beim Ausziehen der Rohre in ihr bestimmtes Loch einzuschnappen hat, _ umIn contrast to known constructions with likewise cylindrical close to -S tubes lying on top of each other, with the number of spring noses of the inner tube and the number of holes of the cover tube are the same, so that each spring nose when pulling out the tubes in her has to snap into a certain hole _ to
ίο den Auszug zu begrenzen und die Rohre festzustellen, besteht die Neuheit der Erfindung darin, daß die Lochanzahl und Lochgröße des Überrohres ungleich zur Federnasenanzahl des Innenrohres ist.ίο limit the extension and determine the pipes, The novelty of the invention is that the number and size of holes in the cover tube is not equal to the number of spring lugs of the inner tube is.
Ist nun bei der bekannten Konstruktion ein Rohr im anderen auch nur gering verdreht worden, so gleiten beim Ausziehen die Federnasen neben den Überrohrlöchern vorbei, und beide Rohre teilten sich in einzelne.With the known construction, one pipe is twisted only slightly in the other the spring lugs slide past the cover tube holes when pulling out, and both tubes split into individual ones.
ao Diesen Nachteil umgeht nun der Gegenstand der Erfindung in folgender Weise:The subject of the invention now circumvents this disadvantage in the following way:
Das Innenrohr 2 (Abb. i) birgt vier Federn 3a bis 3d, welche im Winkel von 90 ° mit ihren Nasen in vier Löchern des InnenrohresThe inner tube 2 (Fig. I) contains four springs 3 a to 3 d , which at an angle of 90 ° with their lugs in four holes of the inner tube
«5 lagern, währenddem das Überrohr 1 nur drei Löcher ia bis ic hat, welche bedeutend breiter und im I2o°-Winkel verteilt sind. Vergleicht man Abb. 1 und 2, A und B, so zeigt Abb. i, daß die Federn 36 in i6 und 30 in i° eingeschnappt sind, währenddem bei Abb. 2 infolge der veränderten Überrohrstellung die Feder 3d in ic sich einlegte.«5 store, while the outer tube 1 has only three holes i a to i c , which are significantly wider and distributed at an I2o ° angle. Comparing Figs. 1 and 2, A and B, as shown in Fig. I, that the springs are snapped 3 6 i 6 and 3 0 i °, whereas in Fig. 2 as a result of the altered overtube position, the spring 3 d in i c pleaded.
Es legt sich also, gleichviel bei welcher Rohrverdrehung mindestens eine Feder im Uberrohrloch ein, so daß ein sich teilen der Rohre vereitelt wird, denn das Größen-, Winkel- und Anzahlverhältnis der Innenrohrfedern ist ungleich zu dem der Überrohrlöcher. Regardless of the rotation of the pipe, at least one spring settles in the Over tube hole, so that a dividing of the tubes is prevented, because the size, The angle and number ratio of the inner tube springs is not the same as that of the outer tube holes.
Abb. 3 veranschaulicht diesen Auszug für Metallröhren stative.Fig. 3 illustrates this extract for metal tube tripods.
