Active steering system for child's pram and push chair

摘要

The system consists of a fixed guide plate (1) with a moveable slide (2). Two traction rollers (7) engage into apertures (13) in the guide plate, which permit displacement of the rollers in two directions. The rollers also engage into apertures (14) in the slide. When a force acts on one of the rollers, it moves in the guide plate apertures to displace the slide in a direction at right angles to its apertures. The slide has two bars (9), and with displacement of the slide a bar acts on steering levers (8) for the wheels.
