Abstract

A construction toy utilizes a plurality of tubular elements which are connectable to each other or are connectable to one or more hollow members. Each of the tubular elements has a first skirt on one end and a second skirt on its opposite end which are of the same size and are utilized to attach the elements to the hollow members. Further, attaching to one of the skirts on one of the ends is a smaller skirt which allows the smaller skirt to be attached to one of the skirts on a further of the tubular elements so as to connect two tubular elements together. The tubular elements have a plurality of convolutions which allow them to be expanded or contracted so as to lengthen or foreshorten the tubular elements as well as allowing the tubular elements to bend during the construction of structures with the components of the invention.
