Claims (6)

1. Gefederter Fahrradrahmen, insbesondere für City- und Trekkingfahrräder, gekennzeichnet dadurch, dass er von einem im wesentlichen aus Steuer-, Ober-, Unter- und Sitzrohr bestehenden Hauptrahmen (1) und einem Hinterbau gebildet wird. Der Hinterbau besteht aus einem Paar Kettenstreben (2) und einem Paar Sitzstreben (4), die in der Nähe der Hinterradaufnahme (6) gelenkig miteinander verbunden sind. Die Kettenstreben sind durch ein in der nähe des am Hauptrahmen angebrachten Innenlagergehäuses befindliches Gelenk (3) mit dem Hauptrahmen (1) verbunden. Dieser Drehpunkt (3) liegt, von der dem Kettenblatt zugewandten Seite gesehen, in einem Bereich (A), der begrenzt wird durch ein gedachtes, um 17° gegen den Uhrzeigersinn aus der Horizontalen gedrehtes Rechteck von 120 mm Breite und 100 mm Höhe, dessen untere Seite mit dem Mittelpunkt im Zentrum des Innenlagergehäuses liegt.
Die Sitzstreben (4) sind über das mittlere Gelenk (10) eines als Wippe ausgeführten Hebels (8) am Sitzrohr (15) des Hauptrahmens (1) angebracht. In der Nähe dieses Gelenkpunktes (10) ist das Oberrohr (9) mit dem Sitzrohr (15) verbunden. Das andere Ende der Wippe (8) stellt eine Gelenkverbindung (11) zu einem Federbein (13) her, das mit seinem anderen Ende über und vor dem Tretlager am Hauptrahmen abgestützt ist. Das Gelenk (10) der Wippe am Hauptrahmen befindet sich, von der dem Kettenblatt zugewandten Seite gesehen, in einem Bereich (B), der umgrenzt wird von einem gedachten, um 17° gegen den Uhrzeigersinn aus der Horizontalen gedrehten Quadrat von 100 mm Kantenlänge, dessen linke untere Ecke sich 155 mm über und 70 mm hinter dem Tretlagerzentrum befindet.
1. Suspension bicycle frame, in particular for city and trekking bicycles, characterized in that it is formed by a main frame ( 1 ) consisting essentially of a steering, upper, lower and seat tube and a rear triangle. The rear triangle consists of a pair of chain stays ( 2 ) and a pair of seat stays ( 4 ), which are hinged together near the rear wheel holder ( 6 ). The chainstays are connected to the main frame ( 1 ) by a joint ( 3 ) located near the inner bearing housing attached to the main frame. This fulcrum ( 3 ), seen from the side facing the chainring, lies in an area (A) which is delimited by an imaginary rectangle of 120 mm wide and 100 mm high, rotated 17 ° counterclockwise from the horizontal lower side with the center in the center of the bottom bracket shell.
The seat stays ( 4 ) are attached to the seat tube ( 15 ) of the main frame ( 1 ) via the central joint ( 10 ) of a lever ( 8 ) designed as a rocker. In the vicinity of this hinge point ( 10 ), the top tube ( 9 ) is connected to the seat tube ( 15 ). The other end of the rocker ( 8 ) creates an articulated connection ( 11 ) to a spring strut ( 13 ), which is supported with its other end above and in front of the bottom bracket on the main frame. The joint ( 10 ) of the rocker on the main frame is, seen from the side facing the chainring, in an area (B) which is delimited by an imaginary square of 100 mm edge length turned by 17 ° counterclockwise from the horizontal, whose lower left corner is 155 mm above and 70 mm behind the bottom bracket center.
2. Gefederter Fahrradrahmen nach Anspruch 1, gekennzeichnet dadurch, dass der Abstand zwischen den Lagermittelpunkten der Gelenke (7) und (10) ein bis dreimal so groß ist wie der Abstand zwischen den Zentren der Lagerungen (10) und (11), und dass der Winkel zwischen den gedachten Verbindungslinien zwischen der Wippenlagerpunkten zwischen 100° und 180° liegt.2. Suspension bicycle frame according to claim 1, characterized in that the distance between the bearing centers of the joints ( 7 ) and ( 10 ) is one to three times as large as the distance between the centers of the bearings ( 10 ) and ( 11 ), and that the angle between the imaginary connecting lines between the rocker bearing points is between 100 ° and 180 °. 3. Gefederter Fahrradrahmen nach einem der vorhergehenden Ansprüche, gekennzeichnet dadurch, dass das Sitzrohr (15) des Hauptrahmens ohne Unterbrechung im wesentlichen bis zum Tretlager verläuft.3. Suspension bicycle frame according to one of the preceding claims, characterized in that the seat tube ( 15 ) of the main frame extends without interruption substantially to the bottom bracket. 4. Gefederter Fahrradrahmen nach einem der vorhergehenden Ansprüche, gekennzeichnet dadurch, dass mindestens ein weiteres Rohr (14) im Hauptrahmen vom oberen Ende des Sitzrohrs (15) zum Oberrohr (9) verläuft.4. Suspension bicycle frame according to one of the preceding claims, characterized in that at least one further tube ( 14 ) in the main frame extends from the upper end of the seat tube ( 15 ) to the top tube ( 9 ). 5. Gefederter Fahrradrahmen nach einem der vorhergehenden Ansprüche, gekennzeichnet dadurch, dass von oben gesehen die Mitte des Abstandes zwischen den Lagern der Lagerstelle (3) der Kettenstreben am Hauptrahmen nicht auf der Mittellinie des Rahmens liegt.5. Suspension bicycle frame according to one of the preceding claims, characterized in that seen from above, the center of the distance between the bearings of the bearing ( 3 ) of the chain stays on the main frame is not on the center line of the frame. 6. Gefederter Fahrradrahmen nach einem der vorhergehenden Ansprüche, gekennzeichnet dadurch, dass oberhalb der Sitzstreben am Sitzrohr (15) Ösen (16) zur Befestigung eines Gepäckträgers angebracht sind.6. Suspension bicycle frame according to one of the preceding claims, characterized in that above the seat stays on the seat tube ( 15 ) eyelets ( 16 ) are attached for fastening a luggage rack.
