Teaching system for modelling mechanisms has interchangeable modules with connectors for modelling different static and kinematic inter-relations

摘要

The system consists of a series of plastic modules (1a, 1b, 1c, 1i) with hollow axles (2a) and connecting members (4) for supporting the modules in relative spatial positions. The modules can have guide straight or spiral guide surfaces that interact with projecting stops (3) on their tubular bodies or axles, and coupling rods (5a) that can join modules together or to supporting bases (15), with both stops and connecting rods being detachable.
