S P E C I F I C A T I O N TITLE: TOY CONSTRUCTION SYSTEM HAVING REUSABLE STRUCTURAL FASTENERS AND INSERTION TOOL THEREFOR INVENTOR: ROBERT L. BRASS ABSTRACT OF THE DISCLOSURE A child's toy construction system, similar in purpose and use to "Erector" sets, is provided having reusable structural fasteners, instead of nuts and bolts. It has a fastener insertion and removal tool which holds and controls the fasten- ers and provides a realistic tool-like feeling. The system includes planar plates and bars to be joined. together to create different structures. They are joined by use of structural fasteners which are inserted through aligned holes in the plates and bars. The fasteners are formed of molded plastic units generally cylindrical in form, having a head at one end (to be grasped and held by the insertion and removal tool) and two elastic, inwardly-distendable prongs or tines at the opposite end. The outer surface of the tines has gripping "steps" positioned and dimensioned so as to enable the fastener to receive and hold either two or three plates. The outer diameter of the fasteners along the prong portion (not including the steps) is approximately equal to the size of the holes in the plates and bars being joined. Accordingly, the fasteners may be inserted into and removed from the holes by pressure which flexes the prongs inwardly so that the prongs and their steps may be extended into or removed from the holes. An insertion tool is provided having means to grip the fastener head and conformingly hold the fastener by means of jaws so that the fastener may be inserted and removed from the holes. -2-
