Spatial Truss

Abstract

A truss includes a first cap, a second cap, a core member, at least two struts, and a fastening member securing the struts to the core member between the first cap and the second cap. The struts are rotatably attached to the core member between the first cap and the second cap of an angle between 15° and 180°.

1 . A truss, comprising:
 a first cap;   a second cap;   a core member;   at least two struts; and   a fastening member securing said struts to said core member between said first cap and said second cap,   wherein said struts are rotatably attached to said core member between said first cap and said second cap of an angle between 15° and 180°.   
   
   
       2 . The truss of  claim 1 , wherein said struts independently comprise a tilt angle of between −30° and 30°. 
   
   
       3 . The truss of  claim 2 , further comprising a clearance angle for tilting said struts, wherein said clearance angle is greater than or equal to said tilt angle. 
   
   
       4 . The truss of  claim 2 , further comprising a dish member span angle, wherein said span angle is greater than or equal to two times of said tilt angle. 
   
   
       5 . The truss of  claim 1 , wherein said struts independently comprise a strut diameter. 
   
   
       6 . The trust of  claim 5 , further comprising a clearance for said struts, wherein said clearance is greater than or equal to half of said strut diameter. 
   
   
       7 . The truss of  claim 1 , wherein said struts comprise a dish member at one end. 
   
   
       8 . The truss of  claim 7 , wherein said dish member comprises a full dish member. 
   
   
       9 . The truss of  claim 7 , wherein said dish member comprises a partial dish member. 
   
   
       10 . The truss of  claim 7 , wherein said dish member is positioned in a cavity between said core member and said first or second cap. 
   
   
       11 . The truss of  claim 1 , wherein said struts comprise a body member and a head member removably attached to said head member, and wherein the head member is rotatably attached to said core member. 
   
   
       12 . The truss of  claim 11 , wherein said struts comprise a dish member at one end. 
   
   
       13 . The truss of  claim 11 , wherein said head member comprises a mating interface configured to fasten said body member to said head member. 
   
   
       14 . The truss of  claim 11 , wherein said head member comprises a rectangular, a conical, or a cylindrical shape. 
   
   
       15 . The truss of  claim 11 , wherein said head member and said body member independently comprise polymer, metal, or wood materials. 
   
   
       16 . The truss of  claim 15 , wherein said head member and said body member independently comprise a polymer material selected from the group consisting of acrylonitrile butadiene styrene (ABS), polypropylene (PP), and combinations thereof. 
   
   
       17 . The truss of  claim 15 , wherein said head member and said body member independently comprise a metal material selected from the group consisting of aluminum, steel, brass, and combinations thereof. 
   
   
       18 . The truss of  claim 1 , wherein said fastening member comprises a bolt or a hex socket screw. 
   
   
       19 . A truss system, comprising:
 a first strut rotatably attached to a first connector joint and a second connector joint;   a second strut rotatably attached to said first connector joint and a third connector joint;   wherein said first and second struts are rotatably attached to said first connector joint between an angle of 15° and 180°.   
   
   
       20 . A method of making a truss, comprising.
 positioning a core member between a first cap and a second cap;   positioning at least two struts on said core member at the desired locations;   fastening said struts to said core member between said first and second caps using a fastening member,   wherein said struts are rotatably attached to said core member between said first cap and said second cap between an angle of 15° and 180°, and comprise a tilt angle from −30° to +30°.
