Abstract: A construction kit such as for the depiction of atoms and their electron arrangements in elements and compounds. This kit comprises a plurality of ring components each having plural connection points for connection to other ring components. The connection points typically comprise male connectors or female connectors with each ring component including one or more male connectors, one or more female connectors, or both male and female connectors, so that multiple ring components can be connected in different configurations to form three-dimensional objects in the form of hemispheres or spheres.

Abstract: The invention relates to a toy construction kit comprising a plurality of elongated rod members of different lengths; and a plurality of joining members. Each joining member is configured and dimensioned to be capable of connecting at least three rod members together around a common vertex point in a weave pattern such that the rods do not pass through the vertex point but are oriented about it in a clockwise or counter-clockwise arrangement. At least some and preferably all rod members are formed with a zig-zag configuration to avoid bending the rod members at vertex points. After making a structure by weaving the rod members and temporarily or permanently connecting them with the joining members, unique and original space frames are obtained. These objects form another embodiment of the invention.
