Connecting assembly for geodesic dome framework construction

Abstract

A connecting assembly consisting of a hub and a plurality of U shaped connecting members for joining the framework of geodesic domes is provided. The hub is formed from a hollow member containing a plurality of radial grooves designed to accept the rectangular end of framing members. The rectangular ends are secured in the grooves by the U shaped connecting members that wrap around the bottom of the grooves of the internal side of the hub and thereafter lie adjacent to the flat end of the framing members. Further, nails, screws or bolts can be used to secure the U shape connecting members to the rectangular ends of the framing members. The frame members extend radially from the center of the hub and are so arranged that the angle between the adjacent framing members is at least 40.degree.. The grooves are so designed that the attached framing members form an angle from 1.degree. to 14.degree. with a plane perpendicular to the central axis of the hub.
