ABSTRACT:
A construction toy system comprises a variety of molded plastic connector elements, arranged to be joined with rod-like struts, to form complex structural units. In the most basic form, the connector elements of the invention have one or more angularly related strut-receiving recesses, each arranged for lateral snap-in reception of a flanged strut. When a strut is snapped in place, it is held firmly against lateral and axial movement. A plurality of single socket connector elements can be connected with a succession of crosswise oriented strut elements to form an articulated structure, either endless or finite in length. Connector elements also may be joined to form connector assemblies with provision for mounting struts in several planar directions, to form a right angle corner structure, for example, or a Tee-shaped structure. To advantage, the construction toy set includes strut elements in graduated sizes according to a predetermined length progression, such that one standard size can serve as the hypotenuse of a right isosceles triangle formed with struts of a smaller size. This enables complex structures to be assembled using right triangular subunits. The struts may be assembled into and/or removed from structures of a substantially rigid character, because of the ability to effect lateral snap-in insertion of the struts. Also disclosed is a simple Device for joining a strut and a connecting element for rotation in unison.
