The invention relates to an articulation for bicycles. A bicycle is equipped with various different bearings and articulations. The majority of these articulations are not rotative, but are configured unnecessarily in prior art as articulations capable of rotation, using anti-friction or sliding bearings. The requirements for articulations in bicycles which are partly contradictory are as follows: high degree of rigidity with the lowest possible weight, absence of play, low bearing friction for optimal responsiveness, no maintenance and no wear. In prior art the solutions have always led to compromises which entail corresponding disadvantages. The novel articulation aims to replace conventional bearings (in the case of the non-rotative bearings on a bicycle), in order to eliminate the aforementioned disadvantages. The articulation (3) thus consists of several flexible, elastic articulation blades (2) which join together the two components (1, 1'). Each end of the respective articulation blade (2) is connected in a rigid manner to one of the two components (1). The articulation blades (2) are arranged in such a way that only a rotational displacement about a rotational axis is permitted and any translatory motion or rotational displacement in another direction is prevented. The articulation (3) can be used for all types of non-rotative bearings on a bicycle, for example, for all bearings in sprung rear structures on a bicycle. |
