  Fahrradkettensicherung. 



   Die Erfindung betrifft eine Schutzvorrichtung gegen das Herausspringen der Kette von Fahrrädern und besteht darin, dass auf dem Rahmen befestigbare Sicherungsorgane vorgesehen sind, deren jedes aus zwei in ihrer Längsrichtung gegeneinander verstellbaren Schienen besteht, an deren freien Enden in der Querrichtung verstellbare, die Kette umfassende   Winkelstücke   angeordnet sind. 



   In der Zeichnung ist die Erfindung in einer beispielsweisen Ausführungsform veranschaulicht, u. zw. zeigt Fig. 1 das eine Sicherungsorgan, welches auf der unteren wagrechten Rahmenstange bei dem hinteren Kettenrade montiert wird, Fig. 2 das zweite Sieherungsorgan, welches auf derselben Rahmenstange bei dem Antriebskettenrad angebracht wird. und Fig. 3 die Gesamtanordnung in Ansicht. 



     Die beiden Schienen a, b   jedes Sicherungsorgans besitzen Langsehlitze und sind durch zwei Schrauben mit Muttern miteinander verbunden. Das freie Ende jeder Schiene ist rechtwinklig abgebogen und mit einer Gewindebohrung versehen. An den Abbiegungen der Schienen sind die Winkelstücke e, d angeordnet, die kurze Schlitze aufweisen, durch welche die die Winkelstücke mit den Schienen verbindenden Schrauben hindurchgehen. Lockert man diese Schrauben, so können die beiden   Winkelstücke   c, d mittels der Langschlitze verschoben und so der Breite der Kette entsprechend eingestellt werden.

   Den verschiedenen Durchmessern der Kettenräder kann dadurch Rechnung getragen werden, dass die Schienen a, b nach Lockerung der beiden Verbindungsschrauben auseinandergezogen oder zusammengeschoben werden.

 die durch die Langschlitz der Schienen a, b hindurchgehen, am Rahmen befestigt. 



     Die gleiche Kettensieherung kann   in   stärkerer Ausführung auch   bei Motorrädern angewendet werden.

  Bicycle chain safety device.



   The invention relates to a protection device against the chain of bicycles jumping out and consists in that securing members which can be fastened to the frame are provided, each of which consists of two rails that are mutually adjustable in their longitudinal direction and at the free ends of which are adjustable in the transverse direction and that encompass the chain are arranged.



   In the drawing, the invention is illustrated in an exemplary embodiment, u. Between. Fig. 1 shows the one safety element which is mounted on the lower horizontal frame bar at the rear chain wheel, Fig. 2 shows the second safety element which is attached to the same frame bar at the drive chain wheel. and FIG. 3 shows the overall arrangement in view.



     The two rails a, b of each safety device have longitudinal braids and are connected to one another by two screws with nuts. The free end of each rail is bent at right angles and provided with a threaded hole. At the bends in the rails, the angle pieces e, d are arranged, which have short slots through which the screws connecting the angle pieces to the rails pass. If you loosen these screws, the two angle pieces c, d can be moved by means of the long slots and thus adjusted to the width of the chain.

   The different diameters of the chain wheels can be taken into account in that the rails a, b are pulled apart or pushed together after loosening the two connecting screws.

 which go through the slot of the rails a, b, attached to the frame.



     The same chain lock can also be used in a stronger version on motorcycles.
