Driving device for child's tricycle comprises drive shaft with idler wheel having two sets of teeth for coupling to shaft, second set angularly immobilized relative to shaft, control mechanism sliding wheel axially for meshing teeth sets

摘要

The device comprises a drive shaft (2), an idler wheel (3) on the shaft provided with a first set of teeth for its coupling to the drive shaft. A second set of teeth (29) for coupling the wheel to the drive shaft are complementary to the first set and angularly immobilized relative to the drive shaft. A control and holding mechanism (10,11,18,24) slides the wheel axially on the shaft between a first position where the first and second teeth sets mesh with each other and a second position where the two teeth sets are separated from each other. An Independent claim is included for a child's tricycle comprising the driving device.
