Gear-change device for a multi-ratio gear-change hub for bicycles or the like

摘要

The invention relates to a gear-change device for a multi- ratio gear- change in bicycles or the like. A gear-change lever of the gear-change device is mounted pivotably on a basis part of the gear- change device and is formed in its middle part as winding body for a gear- change draw cable. The middle part of the gear-change lever is provided with detents with which a ratchet pawl is associated which in turn is pivotably mounted to the basic part of the gear-change device. The ratchet pawl is subject to the return force of the stressed gear-change draw cable and may be provided with its own spring element which is effective in the outward pivoting. The gear-change device comprises only very few parts and can be produced at favorable price with no restriction of functional efficiency.
