Propeller for use in toys

摘要

The propeller has a body which is divided into axial halves, and has blades which can be reversed in order to achieve a desired direction of rotation when exposed to a wind. It may have a central disc (6) to accommodate six pins (9), which support the blades. Each blade may also have two surfaces mounted on a perimeter wire (10). The direction of rotation may then be changed by withdrawing and reinserting the ends of each wire. The propeller may also be fitted with solar cells and lamps, and batteries may be mounted in six small tubes inside the body.
