Description

Exzenterklemmvorrichtung für ineinander verschiebbare Rohre.Eccentric clamping device for pipes that can be slid inside one another.

Gegenstand der Neuerung ist eine Exzenterklemmvorxichtung für ineinander verschiebbare Rohre, insbesondere an Stativen für photografische Zwecke, unter Verwendung einer Drehbaren Klomhülse, deren Verdrehungswinkel durch einen Anschlag begrenzt ist.The object of the innovation is an eccentric clamping device for one another Slidable tubes, in particular on tripods for photographic purposes, using a rotatable Klomhülse whose angle of rotation is limited by a stop is.

Klemmvorrichtungen dieser Art, wobei die Klemmung durch Verdrehen einer Klemmhülse eingeleitet wird, sind bereits in verschiedenen Ausführungsformen bekannt, die aber alle den Nachteil einer aufwendigen und damit teueren Konstruktion, bestehend aus einer Vielzahl einzelner Dreh--und Frästeile aufweisen.Clamping devices of this type, the clamping by rotation a clamping sleeve is introduced, are already in different embodiments known, but all of them have the disadvantage of a complex and therefore expensive construction, consisting of a large number of individual turned and milled parts.

Zur Vermeidung dieses Nachteiles schlägt die Neuerung vor dass die exzentrische Führung für das verschiebbare Inenrohr durch die Bohrung im Bund der Klemmhülse und durch das nach innen umgebördelte obere Ende des Aussenrohres gebildet wird ; der Verdrehungswinkel für die auf dem Aussenrohr konzentrisch gelagerte Klemmhülse ist dabei durch eine Aussparung am oberen Ende des Aussenrohres begrenzt, in die eine an der Innenseite der Klemmhülse angeordnete Nase ragt. I Mit dem Neuerungsvorschlag wird auf einfache Weise mit gering- stem Aufwand an Konstruktionsteilen und damit auch mit gerin- gen Kosten eine sicher funktionierende Exzenterklemmvorrichtung geschaffen ; bei einer Fertigung der Klemmhülse als Formteil aus Kunststoff kann dabei noch eine zusätzliche Vereinfachung,.. und Verbilligung erzielt werden.To avoid this disadvantage, the innovation suggests that the eccentric guide for the displaceable inner tube is formed by the bore in the collar of the clamping sleeve and by the inwardly flanged upper end of the outer tube; the angle of rotation for the clamping sleeve, which is mounted concentrically on the outer tube, is limited by a recess at the upper end of the outer tube, into the one on the inside the clamping sleeve arranged nose protrudes. I. With the proposed innovation, it is easy to with the greatest expenditure of construction parts and thus with little A securely functioning eccentric clamping device created at a cost; If the clamping sleeve is manufactured as a molded part made of plastic, an additional simplification, .. and cheaper can be achieved.

In der Zeichnung wird der Neuerungsvorschlag anhand eines Ausführungsbeispieles in seinen weiteren Einzelheiten näher beschrieben.In the drawing, the proposed innovation is based on an exemplary embodiment described in more detail in its further details.

Fig. l zeigt einen Längsschnitt durch die Klemmvorrichtung, Fig. 2 zeigt einen Querschnitt nach der Linie I-I durch Fig. i. Fig. 1 shows a longitudinal section through the clamping device, Fig. Fig. 2 shows a cross section along the line I-I through Fig. I.

Die Exzenterklemmvorrichtung besteht aus einer konzentrisch auf dem Aussenrohr 1 gelagerten Klemmhülse 2, wobei die exzentrische Bohrung 3 in dem Bund der Klemmhülse 2 und das nach innen umgebördelte obere Ende 4 des Aussenrohres 1 eine exzentrische Führung für das verschiebbar im Aussenrohr angeordnete Innenrohr 5 bilden. Zur Festlegung eines vorbestimmen Verdrehungswinkels der Klemmhülse 2 ist auf deren Innenseite eine Nase 6 vorgesehen, die in eine Aussparung 7 am oberen Ende des Aussenrohres 1 ragt ; die Aussparung 7 erstreckt sich z. B. über den Winkel A.The eccentric clamping device consists of a concentric on the Outer tube 1 mounted clamping sleeve 2, the eccentric bore 3 in the collar the clamping sleeve 2 and the inwardly flanged upper end 4 of the outer tube 1 an eccentric guide for the inner tube, which is slidably arranged in the outer tube 5 form. To define a predetermined angle of rotation of the clamping sleeve 2 a nose 6 is provided on the inside thereof, which is in a recess 7 at the top The end of the outer tube 1 protrudes; the recess 7 extends z. B. over the angle A.

In Losstellung des Innenrohres 5 decken sich die beiden exzentrischen Führungen der Klemmhülse 2 und der Einbördelung 4 im Aussenrohr 1, wobei die Nase 6 am Rand 8 der Aussparung 7 anliegt ; in dieser Stellung kann das Innenrohr 5 beliebig verschoben werden. Durch drehen der Elemmhülse 2 im Uhrzeigersinn, wobei sich die Nase 6 in der Aussparung 7 bewegt, werden die beiden exzentrischen Führungen zueinander verdreht {f und dadurch wird das Innenrohr 5 in seiner jeweiligen Aus- zustellungfestgeklemmt. In the loose position of the inner tube 5, the two eccentric guides of the clamping sleeve 2 and the crimping 4 in the outer tube 1 coincide, the nose 6 resting against the edge 8 of the recess 7; in this position the inner tube 5 can be moved as desired. By turning the Elemmhülse 2 clockwise, wherein the nose 6 moves in the recess 7, the two eccentric guides are rotated with respect to each other {f and as a result, the inner tube 5 is in its respective form infeed clamped.

Zur Sicherung der Klemmhülse 2 in axialer Richtung ist z.B. in einer Sicke 9 am Aussenrohr 1 ein Sprengring 10 angeordnet auf dem die Klemmhülse 2 mit einer Nut 11 einrastet.To secure the clamping sleeve 2 in the axial direction, e.g. Bead 9 on the outer tube 1, a snap ring 10 is arranged on which the clamping sleeve 2 with a groove 11 engages.

Die Sicke 9 dient gleichzeitig als Begrenzungsanschlag für einen Bund 12 am unteren Ende des Innenrohres 5. Die Klemmhülse 2 wird in vorteilhafter Weise als Formteil aus Kunststoff hergestellt.The bead 9 also serves as a limit stop for a federal government 12 at the lower end of the inner tube 5. The clamping sleeve 2 is advantageously made as a molded part made of plastic.
