KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Bei Fahrradbremsen mit seitlich auf den Radkranz wirkenden Bremsbacken fehlt es an einer einfachen Einrichtung, die das Festhalten der Bremsbacken in einer beliebigen Stellung gestattet. Die vorliegende Fahrradbremse ermöglicht dies ohne ein besonderes Gesperre und ohne dafs auf den Bremshebel ein fortgesetzter Druck ausgeübt wird, mittels eines Anzugkeilstückes, das zwischen den Enden der oberen Arme der die Bremsbacken tragenden Hebel angeordnet ist und, mittels des Bremshebels höher oder tiefer eingestellt, durch die Hebel und Backen einen schwächeren oder stärkeren Druck auf den Radkranz zu übertragen und die Bremsbacken in jeder Stellung festzuhalten gestattet.In the case of bicycle brakes with brake shoes acting laterally on the wheel rim, it is missing a simple device that holds the brake shoes in any position allowed. The present bicycle brake enables this without a special locking mechanism and without any continued pressure being exerted on the brake lever, by means of a Wedge piece between the ends of the upper arms of the brake shoes supporting Lever is arranged and, by means of the brake lever set higher or lower, by the Lever and jaws transfer a weaker or stronger pressure to the wheel rim and allows the brake shoes to be held in any position. Die Bremse ist auf der Zeichnung an einem Fahrrad angebracht dargestellt, und zwar zeigt Fig. ι eine Seiten- und Fig. 2 eine Vorderansicht, theilweise im Schnitt.The brake is shown on the drawing attached to a bicycle, namely shows FIG. 1 is a side view and FIG. 2 is a front view, partly in section. .An dem Gestell α des Rades sind zwei um Bolzen b c drehbare doppelarmige Hebel d und e angeordnet, die an ihren unteren Enden Bremshaken h und i tragen, welche mit einem weichen Material, wie Leder, Gummi etc., ausgekleidet sind..At the frame α of the wheel, two double-armed levers d and e , rotatable about bolts bc, are arranged, which at their lower ends carry brake hooks h and i , which are lined with a soft material such as leather, rubber, etc. Die oberen Enden der Hebel d e legen sich gegen ein zwischen ihnen befindliches Anzugskeilstück g, das sich durch eine mit dem Bremshebel verbundene Stange/ auf- und abbewegen läfst. Je nach der Stellung des Keilstückes g werden die Hebel d und e oben mehr oder weniger auseinander- oder zusammenbewegt und dadurch deren untere Enden an den Radkranz geprefst bezw. von demselben entfernt. . Das Keilstück ist mit Nuthen versehen, in welche sich die oberen Enden der Hebel d e einlegen, wodurch eine Drehung des Keilstückes verhindert ist.The upper ends of the levers de lie against a tightening wedge g located between them, which can be moved up and down by a rod connected to the brake lever. Depending on the position of the wedge g , the levers d and e are more or less moved apart or together at the top and thus their lower ends are pressed or respectively against the wheel rim. away from the same. . The wedge piece is provided with grooves in which the upper ends of the levers de insert, whereby rotation of the wedge piece is prevented. Auf die Hebel d e können Federn einwirken, welche dieselben bei hochgezogenem Keilstück von dem Radkranz abziehen (punktirte Stellung, Fig. 2), um eine unnöthige Reibung zu verhindern.Springs can act on the levers de , which pull them off the wheel rim when the wedge is raised (dotted position, Fig. 2), in order to prevent unnecessary friction. Die Bolzen b und c werden so angeordnet, dafs das Rad nur seitlich geprefst, aber weder hochgezogen noch zusammengedrückt wird.The bolts b and c are arranged in such a way that the wheel is only pressed laterally, but is neither pulled up nor compressed. Besondere Gesperre, Fallen und Sicherungen kommen bei dieser Einrichtung in Wegfall.Special locks, traps and safeguards are no longer necessary with this facility. Patent-Anspruch:Patent claim: An Fahrradbremsen mit seitlich auf den Radkranz wirkenden Bremsbacken eine Feststellungs-Vorrichtung, dadurch gekennzeichnet, dafs zwischen den Enden der oberen Arme der die Bremsbacken (h i) tragenden Hebel (d e) ein Anzugskeilstück (g) mit passend geneigten Seitenflächen angeordnet ist, das durch eine Stange ff) mittels des Bremshebels höher und tiefer eingestellt werden kann.A locking device on bicycle brakes with brake shoes acting laterally on the wheel rim, characterized in that between the ends of the upper arms of the levers (de) carrying the brake shoes (hi ) a tightening wedge piece (g) with suitably inclined side surfaces is arranged, which is supported by a Rod ff) can be adjusted higher and lower using the brake lever.
