Abstract
Abstract A construction set for toys and like objects includes pluralities of different basic components. The basic components are a main strut member, an auxiliary strut member, an articulated strut member, an inline connector member, a panel member, and a wheel member. All components, except the panel member, can form identical connection joints with one another anywhere on multiple sides of the components. The panel member has main and auxiliary projections along opposite edges and protuberances mounted on one side of the panel on the main and auxiliary projections. The wheel member has inner and outer rings mounted to one another for relative rotation. The inner ring of the wheel member can receive one of the main strut members in an interfitted relationship.
