  • Connector for interconnecting frame members of a space frame assembly
    Patent number: 11884329
    Abstract: A connector for connecting a frame member to one or more other frame members of a space frame assembly is disclosed. The connector includes a body defining a surface and a projection extending outwardly from the surface along a main axis to define an axial end surface away from the surface. The axial end surface defines a curvature having continuity across an expanse of the axial end surface to facilitate formation of a full penetration weld joint between an end of the frame member and the axial end surface upon a contact of the end of the frame member with the axial end surface.
