KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die nachstehend beschriebene und durch beiliegende Zeichnung erläuterte Erfindung besteht in der Herstellung von Fahrradgestellen aus Hölzern, welche an dem einen Ende oder an beiden gespalten, durch weitere Verarbeitung in die nöthige Form gebracht und unter einander passend verbunden sind.The invention described below and illustrated by the accompanying drawings exists in the manufacture of bicycle racks made of wood, which at one end or split at both, brought into the necessary shape by further processing, and under each other are properly connected.

Die Fig. ia zeigt das rohe Holzstück h, welches an dem einen Ende aufgespalten ist. Werden zwei derartige Stücke auf den bekannten Wegen wie die Theile α und b (Fig. 1) geformt, vorn durch das Zwischenstück d und an den Gabelenden durch die Stahlwinkel c und C1 verbunden, so entsteht ein Holzrahmen adb C1 c, welcher sehr stabil ist und an welchem eine gegenseitige Verschiebung der Gabelarme nicht möglich ist, weil diese sich in dem vollen Holze von α und b vereinigen.Fig. Ia shows the raw piece of wood h, which is split open at one end. If two such pieces are formed in the known ways like parts α and b (Fig. 1), connected at the front by the intermediate piece d and at the fork ends by the steel angles c and C 1 , a wooden frame adb C 1 c is created, which is very is stable and on which a mutual displacement of the fork arms is not possible because they unite in the full wood of α and b .

An diesem Rahmen wird vorn der Kugelkopf e befestigt. Die Sattelstütze s kann entweder unmittelbar im Zwischenklötzchen U1 liegen oder in einer Strebe f verstellbar befestigt werden, deren Enden oben und unten mit den Stücken α und b bezw. deren Klötzchen U1 und b1 passend verbunden sind. Da das Holz b nach Bedürfnifs breit gemacht werden kann, so läfst sich das Tretkurbellager in vorzüglicher Weise am Holze b anbringen und damit der Fehler, den die Stahlrohrgestelle mit ihrer unverhältnifsmäfsig schmalen Lagerbefestigung haben, beseitigen. Das Damenfabrradgestell Fig. 2 zeigt die Verbindung eines Holzes a, welches an beiden Enden gespalten und dann geformt ist, mit einem nur an einem Ende gespaltenen Stück b, das im Arme dx des Kugelkopfes e befestigt ist.. Hinten sind die Gabelenden beider Hölzer α und b wieder durch die Winkel c und C1 und vorn bei a2 durch Schraube und dergl. verbunden, während eine im Arme d des Kugelkopfes befindliche Strebe durch die Gabel von α und b geht und mit beiden befestigt ist. Die Sitzstütze s befindet sich im nicht gespaltenen Theile des Bügels a. The ball head e is attached to this frame at the front. The seat post s can either lie directly in the intermediate block U 1 or be fastened adjustable in a strut f , the ends of which above and below with the pieces α and b respectively. whose blocks U 1 and b 1 are connected appropriately. Since the wood b can be made wide as required, the pedal crank bearing can be attached to the wood b in an excellent manner, thus eliminating the defect that the tubular steel frames have with their disproportionately narrow bearing mounts. The Damenfabrradgestell Fig. 2 shows the connection of a wood a, which is split at both ends and then shaped, with a piece b split only at one end, which is attached in the arms d x of the ball head e .. At the rear are the fork ends of both woods α and b again through the angles c and C 1 and at the front at a 2 by screw and the like. Connected, while a strut located in the arm d of the ball head goes through the fork of α and b and is attached to both. The seat support s is in the non-split part of the bracket a.

Zu bemerken ist noch, dafs die Strebe f im Gestell Fig. 1 auch fortfallen kann.It should also be noted that the strut f in the frame of FIG. 1 can also be omitted.
