Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
193 words
A unitary space frame suitable for forming in a simple two peice mold having a direction of mold opening travel, said frame comprising a plurality of cells, each cell comprising: an upper and a lower grid composed of grid members, said upper grid being offset from said lower grid in plan, said plan being defined by a lateral and longitudinal direction; a plurality of first connecting members, each inter-connecting a grid member in said upper grid and a grid member in said lower grid that are angularly askew, said first connecting members being oriented parallel to the direction of mold opening travel; a pair of side "Z" shaped member means interconnecting said upper grid to said lower grid to resist shear movement of said upper and lower grids in the longitudinal direction; and a center diagonal "V" shaped member means connecting said upper grid and said lower grid to resist shear movement in the lateral direction, the surfaces of said pair of side "Z" shaped member means and said "V" shaped member means being entirely exposed along the direction of mold opening travel for molding through either said upper or said lower grid.
Claim 2
Dependent Claim
193 words
A unitary space frame suitable for forming in a simple two peice mold having a direction of mold opening travel, said frame comprising a plurality of cells, each cell comprising: an upper and a lower grid composed of grid members, said upper grid being offset from said lower grid in plan, said plan being defined by a lateral and longitudinal direction; a plurality of first connecting members, each inter-connecting a grid member in said upper grid and a grid member in said lower grid that are angularly askew, said first connecting members being oriented parallel to the direction of mold opening travel; a pair of side "Z" shaped member means interconnecting said upper grid to said lower grid to resist shear movement of said upper and lower grids in the longitudinal direction; and a center diagonal "V" shaped member means connecting said upper grid and said lower grid to resist shear movement in the lateral direction, the surfaces of said pair of side "Z" shaped member means and said "V" shaped member means being entirely exposed along the direction of mold opening travel for molding through either said upper or said lower grid.
Claim 3
Dependent Claim
