Abstract
Abstract A three dimensional inner shear form is stamped or formed from any desired material and consists of a plurality of three sided half cubes interconnected together by the bases thereof. The apices of the half cubes are flattened and may be apertured for weight purposes. Inner or outer skins may be adhesively secured across the flattened apices to form a panel structure having considerable strength and which can be planar or can be formed into spherical, circular or warped forms. Adjacent sections of the shear form can be joined by elongated connectors which are secured along mating edges of sections, the connection being formed by an elongated strip of shear form which fits over the angles and planes of the adjacent edges of the adjacent sections.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
48 words
A SHEAR FORM STRUCTURE COMPRISING A THREE DIMENSIONAL CORE FROMED FROM A PLURALITY OF HOLLOW, THREE-SIDED, HALF CUBES INTERCONNECTED TOGETHER ALONG BASE EDGES THEREOF, WITH ALTERNATIVE APICES BEING PERPENDICULAR TO AND ON OPPOSITE SIDES OF THE CENTRAL PLANE OF SAID STRUCTURE, SAID APICES BEING FLATTENED TO FORM FRUSTUMS.
Claim 2
Dependent Claim
48 words
A SHEAR FORM STRUCTURE COMPRISING A THREE DIMENSIONAL CORE FROMED FROM A PLURALITY OF HOLLOW, THREE-SIDED, HALF CUBES INTERCONNECTED TOGETHER ALONG BASE EDGES THEREOF, WITH ALTERNATIVE APICES BEING PERPENDICULAR TO AND ON OPPOSITE SIDES OF THE CENTRAL PLANE OF SAID STRUCTURE, SAID APICES BEING FLATTENED TO FORM FRUSTUMS.
Claim 3
Dependent Claim
40 words
THE STRUCTURE ACCORDING TO CLAIM 1 WHICH INCLIDES AT LEAST ONE PLANAR SKIN SECURED ACROSS SAID APICES TO ENCLOSE AT LEAST ONE SIDE OF SAID CORE THEREBY DEFINING A POLURALITY OF DIAGONALLY EXTENDING CHANNELS BETWEEN SAID SKIN AND SAID CORE.
Claim 4
Dependent Claim
61 words
THE STRUCTURE ACCORDING TO CLAIM 1 WHICH INCLUDES A CONNECTOR STRIP FOR SECURING ADJACENT SECTION OF CORE TOGETHER SAID CONNECTOR STRIP HAVING A DIMENSIONAL CONFIGURATION THE SAME AS THE CONFIGURATION OF THE ADJACENT EDGES OF THE SECTION OF CORE BEING JOINED WHEREBY SAID STRIP NESTS UPON AND ENGAGES SAID ADJACENT EDGES, AND MEANS TO SECURE SAID STRIP TO SAID ADJACENT EDGES.
Claim 5
Dependent Claim
61 words
The structure according to claim 2 which includes a connector strip for securing adjacent sections of core together, said connector strip having a dimensional configuration the same as the configuration of the adjacent edges of the section of core being joined whereby said strip nests upon and engages said adjacent edges, and means to secure said strip to said adjacent edges.
Claim 6
Dependent Claim
63 words
The structure according to claim 3 in which said connector strip comprises a plurality of plates having a configuration similar to the configuration of one of the sides of said half cubes, and reverse angulated gusset portions connecting said plates together, said gusset portions having a configuration similar to the configuration of the adjacent sides of the adjacent half cubes being connected together.
Claim 7
Dependent Claim
80 words
The structure according to claim 4 in which said connector strip comprises a plurality of plates having a configuration similar to the configuration of one of the sides of said half cubes, and reverse angulated gusset portions connecting said plates together, said gusset portions having a configuration similar to the configuration of the adjacent sides of the adjacent half cubes being connected together, said plates being hexagonal when viewed in elevation to conform to the truncated configuration of said sides.
Claim 8
Dependent Claim
66 words
The structure according to claim 3 in which said connector comprises a plurality of plates situated in zig zag relationship one with the other, and an angulated gusset plate connecting said first plates together, said first plates engaging the adjacent sides of said sections lying in alternate planes, said gusset plate engaging alternate sides of the adjacent sections lying at an angle to the adjacent sides.
Claim 9
Dependent Claim
67 words
