Abstract
The problem of providing a greater tolerance in the hole diameters of toy blocks held together by frictionally fitting resiliently deformable connector elements is resolved by connector structural features. Thus, the connector element has a hollow cylindrical body of resiliently deformable plastic with separate slots extending axially along the cylindrical circumferential walls on diametrically opposite sides of the cylindrical body and at opposite ends. This provides independent conformation to mating block holes for each end so that entry of one end into a smaller hole will not deform the connector to decrease friction at the opposite end, and thus a tight fit will result in a larger hole.
