International ClassA63H 033/10AbstractRedundant joints for a wide variety of redundant-joint structures have three-way plumbing elbows (1, 5, 6) with coupling sleeves (2) into which two-way plumbing elbows (9, 13, 14) are inserted and rotated to form an infinite variety of angles of joining edges or sides of structural assemblies bordered by cylindrical beams (15) inserted into sleeves (12) in the two-way elbows. The three-way elbows can have different angles for particular structures than employed for conventional plumbing uses. For other structures, the three-way elbows have the same or similar angles as those employed for conventional plumbing. Two-way elbows with a coupling sleeve at one end and a pipe-sized opposite extension employed for particular forms also can have different or the same angles as employed for conventional plumbing.Field of SearchPolyhedralPolyhedral Three-dimensional space-defining Geometry, trigonometry, or physical mathematic model structure Molecular model or display having discrete element representing atom or radical Block or like manually manipulatable object having indicia or picture on face thereof, or three-dimensional form for demonstrating shape Serially connected, adjustable | |
