Abstract
Abstract A lattice grid assembly comprising a plurality of spaced, parallel, longitudinal rods secured to lateral clamping bars. The bars have pockets formed by resilient gripping members adapted to engage bosses on the sides of the rods when they are inserted into the pockets. Pairs of adjacent gripping members are urged against the rods by a screw tightened wedge interposed between each pair.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
75 words
A lattice grid assembly, comprising: a. a plurality of longitudinal rods each having bosses thereon, b. a plurality of lateral clamping bars extending transversely across the rods for holding them in a spaced relationship to thereby form a grid pattern, each clamping bar including a plurality of elastically deformable gripping members adapted to engage the bosses on the rods, and c. a plurality of tensioned wedge members for urging the gripping members against the rods.
Claim 2
Dependent Claim
75 words
A lattice grid assembly, comprising: a. a plurality of longitudinal rods each having bosses thereon, b. a plurality of lateral clamping bars extending transversely across the rods for holding them in a spaced relationship to thereby form a grid pattern, each clamping bar including a plurality of elastically deformable gripping members adapted to engage the bosses on the rods, and c. a plurality of tensioned wedge members for urging the gripping members against the rods.
Claim 3
Dependent Claim
27 words
A lattice grid assembly as claimed in claim 1, wherein the gripping members are arranged in pairs and a single wedge member is interposed between each pair.
Claim 4
Dependent Claim
51 words
A lattice grid assembly as claimed in claim 2 wherein each clamping bar has a plurality of channel recesses and a pair of gripping members are positioned in each recess to thereby form two pockets between the gripping members and the side walls of the recess for receiving the longitudinal rods.
Claim 5
Dependent Claim
85 words
A lattice grid assembly as claimed in claim 3 wherein each gripping member has a slanted face for engagement by a wedge member, a nose projection on the same side as the slanted face and a shoulder on the opposite side for retainingly engaging the boss oN a longitudinal rod, and each wedge member has lateral projections for catching under the slanted faces of the gripping members during an intermediate assembly stage and enlarged end pieces for resting against the nose projections during said stage.
Claim 6
Dependent Claim
43 words
A lattice grid assembly as claimed in claim 2, further comprising a cross bar on which at least one of the clamping bars is mounted by bolt means secured to the wedge members and extending through the clamping bar and the cross bar.
Claim 7
Dependent Claim
19 words
A lattice grid assembly as claimed in claim 5 further comprising means for securing two clamping bars together end-to-end.
