three dimensional model of molecular structure and device for assembly and disassembly of the model

摘要

The three-dimensional model has plastics modules (1), each representing an atom of the molecular structure. These are connected by assembly parts (2) introduced into housings in each module. The housing shape matches that of the assembly parts, which are basically cylindrical. - The surface of both are corrugated (3,6,4,7), with alternate matching ridges and hollows. The ridges (3) and hollows (4) are made so that their axes are parallel to that of the assembly part. The entry zone (5) of each housing is conical and the model has pivoted hand grips for easy handling.(1/3)
