Abstract
Abstract A latticework is formed from a plurality of cell-forming elements connected by bolts to anchors. Each element has at least two connection portions each formed with at least one lateral face abuttable with a similar face of another like element. The anchor is formed with a threaded hole having a counterbore into which a tooth or tab formed on each of a pair of connection portions engage when a bolt is screwed into the hole and its head bears against the respective connection portions. Tiles which may carry a schematic drawing of the circuitry they cover or which may carry circuit elements are fitted over each cell of the lattice.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
130 words
A lattice assembly comprising: a plurality of generally planar rigid cell-forming lattice elements each having a connection portion formed with at least one arc-segmental tab projecting laterally from the plane of the respective element, said connection portions meeting at corners of the cells; a plurality of anchors at said corners and each formed with a threaded hole having a counterbore, said tabs at each corner being engaged in the respective counterbore; and a plurality of fastener bolts each having a threaded shank received in said hole and a head engaging and overlying the respective connection portions of the elements having tabs in the respective counterbore to clamp said respective connection portions against said anchor, said tabs lying between a surface of said shank and a wall of the respective counterbore.
Claim 2
Dependent Claim
130 words
A lattice assembly comprising: a plurality of generally planar rigid cell-forming lattice elements each having a connection portion formed with at least one arc-segmental tab projecting laterally from the plane of the respective element, said connection portions meeting at corners of the cells; a plurality of anchors at said corners and each formed with a threaded hole having a counterbore, said tabs at each corner being engaged in the respective counterbore; and a plurality of fastener bolts each having a threaded shank received in said hole and a head engaging and overlying the respective connection portions of the elements having tabs in the respective counterbore to clamp said respective connection portions against said anchor, said tabs lying between a surface of said shank and a wall of the respective counterbore.
Claim 3
Dependent Claim
26 words
The assembly defined in claim 1, further comprising a plurality of mosaic titles of polygonal outline each having corners releasably engaging the heads of respective bolts.
Claim 4
Dependent Claim
38 words
The assembly defined in claim 2 wherein said bolts have a shank formed adjacent the bolt head with an unthreaded region, said connection portions each being formed with a curved edge snugly engageable against a respective unthreaded region.
Claim 5
Dependent Claim
44 words
The assembly defined in claim 3 wherein each of said connection portions is formed to each side of said curved edge with a lateral face adapted to abut a similar face of a similar portion of another such element, said edge being circularly arcuate.
Claim 6
Dependent Claim
28 words
The assembly defined in claim 4 wherein said hole and said counterbore are cylindrical and coaxial, said tab having the shape of a segment of a cylindrical annulus.
Claim 7
Dependent Claim
32 words
The assembly defined in claim 5 wherein said elements are formed with a plurality of arms extending from a common center and each having at its free end one such connection portion.
Claim 8
Dependent Claim
19 words
The assembly defined in claim 5 wherein said elements are annular and have corners formed with said connection portions.
