Abstract:
The present invention provides a bicycle comprising wheels and a frame supported on the wheels. The frame includes a seatstay assembly defining a seatstay axis and including a spring assembly having a spring member (e.g., a leaf spring) at an angle of at least 5 degrees relative to the seatstay axis. The spring member has a width that is at least 4 times larger than its thickness. The present invention also provides a bicycle comprising a frame that includes a seat tube and a seatstay assembly defining a seatstay axis. The seatstay assembly includes a spring member offset from the seatstay axis and non-parallel to the seatstsay axis. In one embodiment, the seatstay assembly further includes a seatstay tube, and the spring member includes a rear portion secured to the seastay tube. The spring member can also include a front portion secured to a seat tube of the bicycle frame.
Abstract:
L'invention propose un système de suspension d'un guidon (22) de vélo, du type dans lequel le système est monté sur un ensemble (18) de direction du vélo qui est monté pivotant par rapport à un cadre (12) du vélo par l'intermédiaire d'une structure d'articulation (20), du type dans lequel le système comporte au moins deux bras (48, 50) qui s'étendent depuis l'ensemble de direction (18) et qui sont superposés dans la direction de l'axe (Al) de pivotement de l'ensemble de direction (18), et du type dans lequel les deux extrémités libres des bras sont liées l'une à l'autre par une pièce de liaison (52), caractérisé en ce que les bras superposés (48, 50) sont disposés de part et d'autre de la structure d'articulation (20) le long de l'axe (A1) de pivotement.

Die Erfindung betrifft einen Fahrradrahmen mit einem Grundrahmen und weningstens einer an diesem Grundrahmen angeordneten Einrichtung (14, 60), die als Strebenkonstrucktion gestaltet ist und einen Aufnahmebereich zur Aufnahme eines Rades aufweist, eine Fahrradgabel, sowie ein Verfahren zur Herstellung eines Fahrradrahmens.
Abstract:
This invention relates to a vehicle suspension system where two or more flexible members (3401a, 3402a) are arranged in a non- planar way with a distance there between. These flexible members (3401a, 3402a) are being rigidly mounted between a frame structure (109) of a vehicle and a wheel structure (111) of the vehicle and the arrangement of the flexible members (3401a, 3402a) is so as to provide guided suspension and being resistive against forces other than those in the intended direction of the suspension movement.
Abstract:
A bicycle seat support that resiliently supports a bicycle seat. The support comprises an upper engagement member adapted to support a bicycle seat, a lower engagement member adapted to engage a bicycle frame, and a compliant support assembly coupling the upper engagement member to the lower engagement member. The compliant support assembly includes a first and second cantilevered springs defining a gap, and a resilient member (e.g., an elastomer) positioned in the gap. The bicycle seat support can include an elbow joint coupling the lower engagement member to the compliant support assembly. Preferably, the elbow joint comprises an upper portion that sandwiches the first and second cantilevered springs, and a lower portion positioned in a recess in the lower engagement member. The lower engagement member can also include a resilient bump stop adapted to limit downward movement of the upper engagement portion.
