Water guideway for unpowered floating toys, for use in gardens

摘要

The guideways are intended to allow unpowered toys to be propelled around a course, or for driving playthings such as paddle wheels. A fluid flow similar to that on a river bed is produced in mainly half-shell channels, which are accessible from above. The channels can be assembled to form varied shapes from handy, straight, bent, or branched channel modules, and which have releasable connections. The flow enters the channels obliquely from below, or from the side, producing a mainly circulating velocity component in the guideway. The so-called "drive"-channels have motor-driven fans (16.2) in parallel channels under the main channel and are aligned with the guideway tubing in order to produce the desired direction of circulation.
