Multidirectional linking system for use in constructions

Claim 1

A connector for interconnecting a plurality of rods into a spatial structure wherein each of said rods comprises a longitudinal axis, and wherein said connector comprises: a first central body member having a first longitudinal axis; a plurality of first lug members projecting radially outwardly from and spaced around said first central body member, each of said first lug members having a central axis directed transverse to and intersecting said longitudinal axis of said first central body member at a predetermined common point; a second central body member having a second longitudinal axis coaxial with said longitudinal axis of said first central body member and secured to said first central body member; a plurality of second lug members projecting radially outwardly from and spaced around said second central body portion, each of said second lug members having a central axis directed transverse to and intersecting said second longitudinal axis at said common point; keying means for detachably connecting and for angularly positioning said first central body member with said second central body member; and marking means indicating a plurality of alignment marks corresponding to a plurality of different points of attachment of said rods with said connector provided on each of said first and second lug members for substantially aligning said longitudinal axes of said rods with said central axes of said first and second lug members within predetermined marked limits, each one of said plurality of alignment marks defining a predetermined angular position formed between said longitudinal axis of each one of said rods and said central axes of said first and second lug members such that interconnection of said rods with said connector via said first and second lug members at any said predetermined angular position transmits and converges forces from said rods to said connector at said common point.
