ABSTRACT:
A construction element, which may be used in constructing flexible universal joints for a variety of geometrical structures such as assembly toys and in combination with rods to particularly construct a cube-octahedron throwing toy, is disclosed wherein the element comprises a section of elastic tubing having diametrically opposed cutouts at its center to form a transverse opening adapted to receive a similar piece of tubing or other member. By inserting one of such elements through the cutouts in another of the elements until the cutouts register, they may be compressively held together and form a universally flexible, self-centering, cruciform joint which can be connected to four rod-like members and used in combination with like elements and members in assembling various polyhedral structures such as the preferred embodiment of a manipulatable throwing toy. By virtue of their elasticity, more than two tube elements can be connected together into a single multielement joint or one or more can be connected to an alternate unitized cruciform joint embodiment.
