Abstract

Die Erfindung betrifft eine Knickkurbel (1) mit einem Mittelstück (2) und zwei schaftförmigen Endteilen (3,4), von denen ein Endteil (3) zum manuellen Kurbeln versehen und das andere Endteil (4) mit einer zu drehenden Stange verbindbar ist, wobei das Mittelstück (2) über je ein Knickgelenk (13,16) mit den beiden Endteilen (3,4) verbunden ist. Damit die Knickkurbel (1) aus möglichst wenigen, verschiedenen Einzelteilen besteht, die möglichst spanlos gefertigt und in einfacher Montage zusammengebaut werden kann, sieht die Erfindung vor, dass die Knickgelenke (13,16) als Scharniergelenke mit mehreren, formschlüssig ineinander greifenden Flachstücken (21) ausgebildet sind, dass das eine Gelenkendstück (13) aus mindestens drei beabstandeten Flachstücken (21) und das andere Gelenkendstück (16) aus mindestens zwei Flachstücken (18) besteht, dass das mittlere Flachstück (21) des Gelenkendstücks (13) an den Abstand der beiden Flachstücke (18) des Gelenkendstücks (16) angepasst ist, dass die Abstände der äußeren Flachstücke (21) von dem mittleren Flachstück des Gelenkendstücks an die Dicke der Flachstücke (18) des Gelenkendstücks (16) angepasst sind, dass zumindest die Flachstücke (18) des Gelenkendstücks (16) zumindest auf den Außenseiten mit abstehenden Rastzapfen (17) versehen sind, dass die äußeren Flachstücke (21) des Gelenkendstücks (13) mit Rastaufnahmen (14) für die Rastzapfen (17) des Gelenkendstücks (16) versehen sind, dass die äußeren Flachstücke (21) des Gelenkendstücks (13) mit zu den Rastaufnahmen (14) führenden Einführungsnuten (15) versehen sind, dass die Flächen zwischen den Flachstücken (21) der beiden Gelenkendstücke (13) als Anschlagflächen (19,24) zur Begrenzung der beidseitigen Knickbewegung dienen und dass die beiden Gelenkendteile (16) des Kurbelstücks (3), sowie das Gelenkendteil (13) des Mittelstücks (2) rastend miteinander verbindbar sind.

The invention relates to a folding crank (1) having a center piece (2) and two shaft-shaped end parts (3,4), one end part (3) of which is provided for manual cranking and the other end part (4) is connectable to a rod to be turned, wherein the center piece (2) via a respective articulated joint (13,16) is connected to the two end portions (3,4). In order for the articulated crank (1) to consist of as few, different individual parts as possible, which can be manufactured as non-cutting as possible and assembled in a simple assembly, the invention provides that the articulated joints (13, 16) can be used as hinged joints with a plurality of flatly interlocking flat pieces (21 ) are formed, that the one hinge end piece (13) of at least three spaced flat pieces (21) and the other hinge end piece (16) consists of at least two flat pieces (18), that the middle flat piece (21) of the joint end piece (13) at the distance adapted to the two flat pieces (18) of the joint end piece (16) that the distances of the outer flat pieces (21) from the middle sheet of the joint end piece to the thickness of the flat pieces (18) of the joint end piece (16) are adapted, that at least the flat pieces ( 18) of the joint end piece (16) are provided at least on the outer sides with protruding latching pin (17) that the outer flax (21) of the hinge end piece (13) are provided with latching receptacles (14) for the latching pins (17) of the hinge end piece (16) such that the outer flat pieces (21) of the hinge end piece (13) have insertion grooves leading to the latching receivers (14) ( 15) are provided, that the surfaces between the flat pieces (21) of the two Gelenkendstücke (13) serve as abutment surfaces (19,24) for limiting the two-sided buckling movement and that the two Gelenkendteile (16) of the crank piece (3), and the Gelenkendteil (13) of the center piece (2) can be connected to one another in a latching manner.
