KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die Erfindung betrifft eine Fahrradsatteltragfeder, welche am Bolzen der Sattelklemme in einer Kröpfung befestigt ist. Das Wesen der Erfindung besteht darin, daß diese Kröpfung so tief ausgebildet ist, daß der Schwerpunkt des ganzen Federsystems unterhalb des Aufhängepunktes zu liegen kommt, und daß erforderlichenfalls eine Festklemmvorrichtung der Feder gegen die FahrradrThe invention relates to a bicycle saddle suspension spring which is attached to the bolt of the saddle clamp is attached in a crank. The essence of the invention is that this Crank is so deep that the focus of the whole spring system is below of the suspension point comes to rest, and that if necessary a clamping device the spring against the Fahrradr

Fig. ι der beiliegenden Zeichnung zeigt die Seitenansicht, Fig. 2 die Oberansicht, Fig. 3 die Vorderansicht der Fahrradsattelfeder. Fig. Ι the accompanying drawing shows the side view, Fig. 2 the top view, 3 shows the front view of the bicycle saddle spring.

Die Tragfeder ist sowohl in ihrem hinteren als vorderen Teile schraubenförmig gewunden, Der Sattelsitz ruht nur auf den hinteren Federteilen, deren Enden f (Fig. 2) lang ausgezogen sind, um ein möglichst weiches Federspiel und eine gute Auflagerfläche für den Sattelsitz ρ zu sichern.The suspension spring is helically wound both in its rear and front parts, the saddle seat rests only on the rear spring parts, the ends f (Fig. 2) of which are extended to ensure the softest possible spring play and a good support surface for the saddle seat ρ .

Bei ruhiger Fahrt auf glatter Bahn wird das Gewicht des Fahrers fast ausschließlich durch die hinteren Teile der Federn getragen.When driving smoothly on a smooth track, the weight of the driver becomes almost exclusively carried by the rear of the feathers.

Erst bei unebener Bahn oder bei plötzlich auftretenden Stößen neigt sich der Sitz mehr nach vorn und belastet auch die vorderen Federenden ν (Fig. 1). Hiernach wirken die hinteren Federteile als eigentliche Tragfedern, die vorderen Teile dagegen in der Hauptsache als Hülfstragfedern, wodurch einerseits ein weicher Sitz, andererseits eine Überlastung der hinteren Federteile und deren Bruch verhindert wird. Zur Erzielung einer seitlichen Beweglichkeit des Sattels, entsprechend den Tretbewegungen des Fahrers, stehen die hinteren Federteile wesentlieh weiter voneinander entfernt als die vorderen Federenden.Only when the track is uneven or when sudden impacts occur does the seat tilt more forward and also load the front spring ends ν (Fig. 1). According to this, the rear spring parts act as actual suspension springs, while the front parts mainly act as auxiliary suspension springs, which on the one hand ensures a soft fit and on the other hand prevents overloading of the rear spring parts and prevents them from breaking. To achieve lateral mobility of the saddle, corresponding to the pedaling movements of the driver, the rear spring parts are essentially further apart than the front spring ends.

Um die erforderliche Tieflage des Schwerpunktes für das Federsystem zu schaffen, ist. der zwischen den Windungen gebogene Federteil genügend tief durchgekröpft. Diese Art der Federaufhängung gestattet bei Verwendung von Rundstahl die Festhaltung der Tragfedern zwischen zwei glatten Klemmbacken (Fig. 3); auch kommen die sonst für die Einstellung der Sattelfläche erforderlichen Verzahnungen an der Sattelklemme in Fortfall. Gleichzeitig werden die gefährlichen Bruchmomente am Aufhängungspunkt der Federn vermindert.To create the required lower position of the center of gravity for the spring system, is. the spring part bent between the coils is bent sufficiently deep. This kind The spring suspension allows the suspension springs to be held between two smooth clamping jaws when using round steel (Fig. 3); there are also those otherwise required for adjusting the saddle surface Toothings on the seat clamp no longer available. At the same time, the dangerous Breaking moments at the suspension point of the springs are reduced.
