Pivot structure and pivot joint for construction toy assemblies

Abstract

A pivot structure comprises a one-piece plastic support including a parallelepiped rectangular body having a sidewall and a pivot bracket projecting from this sidewall. It comprises also a one-piece plastic bar section which includes a base plate, a columnar connector having an essentially constant cross-section and projecting from one face of the base plate; an L-shaped connector with a first leg upstanding at one end from one edge of the base plate, spacedly of the columnar connector, and a second leg projecting outwardly from the other end of the first leg, away from the columnar connector. The support section and the bar section are interconnected by a pivot arrangement on both the bracket of the support section and on the free end of the second leg of the L-shaped connector to allow for relative pivotal movement of the support section and bar section about an axis which is parallel to the sidewall of the support section. The pivot arrangement can be operatively connected to toy assembly block including a hollow plastic body having an endwall, a top wall and a hollow connector plug on the top wall and opening into the hollow body. This is achieved by having the pivot arrangement properly dimensioned so that the columnar connector project from the base plate and fits snugly into the hollow connector plug of the toy assembly block.
