Abstract
A construction set is made up of a plurality of detachably chainable links capable of being pivotally attached to one another to form stable geometric structures. Detents are provided at a plurality of pivot positions so as to preferentially hold the engaged links in stable and precise positions relative one to another.

A modular building piece adapted to releasably attach to another in a pivoting relationship, the piece comprising:
- two resilient spaced elements in parallel opposition at a first end providing a cavity therebetween, the cavity facing away from the piece along a centerline between the ends of the piece;
- a projection at the other end aligned along the centerline adapted to seat in the cavity of another piece;
- dimples and bumps defining a first axis at the first end and a second axis at the second end, the dimples adapted to pivotally and releasably engage bumps of the other piece about one of the axes, the bumps adapted to pivotally engage the dimples of the other piece about the other axis, and detent means for releasably fixing the piece in a selected one of a plurality of angular positions about one of the axes relative to an attached piece.
A construction set comprising two links pivotally connectable in end to end relation, a first link comprising first pivot means at one end thereof defining a first axis and another first pivot means at the other end thereof defining a second axis;
- a second link comprising second pivot means at one end thereof defining a third axis and another second pivot means at the other end thereof defining a fourth axis;
- both of the first pivot means of the first link adapted to pivotally and releasably engage either of the second pivot means of the second link such that the axis defined by the engaged first pivot means is coincident with the axis defined by the engaged second pivot means;
- bias means for biasing the engaged first pivot means of the first link and the engaged second pivot means of the second link into a stable pivoting engagement;
- the first and second links further comprising detent means for releasably fixing the angular orientation of the first link relative to the second link about the coincident axes in one of a plurality of predetermined angular orientations.
Two modular building pieces adapted to releasably attach one to another in a pivoting relationship, the first piece comprising two spaced elements at two opposing ends thereof providing a cavity therebetween;
- the second piece comprising a projection at two ends thereof adapted to seat in a cavity of the first piece;
- dimples on one piece and bumps on the other piece defining a first axis at one end of the first piece and a second axis at one end of the second piece, the dimples on the one piece adapted to pivotally and releasably engage the bumps of the other piece when the first axis is conicident with the second axis, the two pieces further comprising means for releasably fixing the first piece in a selected one of a plurality of angular positions about the coincident axes relative to the second piece.
