ABSTRACT:
A kit for assembling a geodesic structure is disclosed as including a plurality of polygonal panels (12) preferably of triangular shapes so as to be assembled to define a sphere (10). Each panel is of a unitary construction molded from plastic and includes a first set of male lugs (20) and a second set of female lugs (22) projecting from its sides (14). The female lugs (22) are arranged in pairs and spaced along the length of the associated panel side so as to receive a male lug (20) on one side of another panel in order to provide a connection (16) therebetween. Outer ends on both the male and female lugs include connection surfaces (24, 26) that snap into engagement with each other as the male lug (20) of each connection (16) is inserted between the associated female lugs (22) in order to secure the panel sides (14) and thereby prevent relative movement between the panels lengthwise and transversely with respect to the length of each side. The preferred construction of each triangular panel includes elongated side members (18) that define a central opening of the panel and the sides thereof with the connection lugs (20, 22) projecting outwardly therefrom in the plane of the panel . A unitary injection molding (28) of plastic incorporates six triangular panels of constructions that allow the assembly of a geodesic sphere from thirty such moldings. A die (40) for injection molding the panels includes insert balls (46) for providing depressed connection surfaces on the lugs. Resilient mounts (48) for the balls permit movement thereof on a section of the die such that a molded panel can be easily removed.
