Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
158 words
A cabling system for reinforcement of an inflatable building structure comprising a latticework of crisscrossed cables arranged to extend over the entire building with substantially all of the cables which meet a lower peripheral edge of the structure being arranged diagonally at a uniform angle of substantially less than ninety degrees to that edge and with substantially all of said cables which meet a lower peripheral edge being paired with and meeting an opposite diagonally extending cable at said peripheral edge, the members of each of said pairs of diagonally opposite extending cables being formed from one continuous cable extending down on one diagonal to the edge and turning back up on the other diagonal, anchoring means to hold said continuous cable at the turn between diagonals, said anchoring means comprising a sheave arranged to permit an adjustment in length between the associated diagonal cables wherein one diagonal cable becomes longer and the other diagonal cable becomes shorter.
Claim 2
Dependent Claim
158 words
A cabling system for reinforcement of an inflatable building structure comprising a latticework of crisscrossed cables arranged to extend over the entire building with substantially all of the cables which meet a lower peripheral edge of the structure being arranged diagonally at a uniform angle of substantially less than ninety degrees to that edge and with substantially all of said cables which meet a lower peripheral edge being paired with and meeting an opposite diagonally extending cable at said peripheral edge, the members of each of said pairs of diagonally opposite extending cables being formed from one continuous cable extending down on one diagonal to the edge and turning back up on the other diagonal, anchoring means to hold said continuous cable at the turn between diagonals, said anchoring means comprising a sheave arranged to permit an adjustment in length between the associated diagonal cables wherein one diagonal cable becomes longer and the other diagonal cable becomes shorter.
Claim 3
Dependent Claim
15 words
A system as claimed in claim 1 wherein said anchoring means sheave is freely rotatable.
Claim 4
Dependent Claim
44 words
A system as claimed in claim 2 wherein said rotatable sheave is positioned and arranged to rotate upon an axis substantially perpendicular to a plane defined by the latticework of cables in the vicinity of the sheave when the inflatable building structure is inflated.
Claim 5
Dependent Claim
30 words
A system as claimed in claim 1, or claim 2, or claim 3, wherein said uniform angle of substantially less than ninety degrees is in the neighborhood of sixty degrees.
Claim 6
Dependent Claim
28 words
A system as claimed in claim 1 wherein the minimum diameter of said sheave is in the neighborhood of at least nine times the diameter of the cable.
Claim 7
Dependent Claim
66 words
A system as claimed in claim 3 wherein said anchoring means further comprises a support bracket for said sheave consisting of an L-section channel arranged to be anchored to a base structure for the inflatable building with said sheave being attached to an upstanding leg of said L-channel and with the other side of said L-channel being arranged to be attached to the building base structure.
Claim 8
Dependent Claim
144 words
A system as claimed in claim 6 wherein said sheave is mounted by means of an axle upon the side of the upstanding leg of said L-section support bracket at which the base leg of said support bracket is attached, and wherein there is provided a locking plate mounted upon said sheave axle at the outside of said sheave and having a slotted center opening to permit the raising and lowering of said locking plate to permit the insertion of the cable onto the sheave when the locking plate is raised and to lock the cable upon the sheave when the locking plate is lowered, the locking plate being arranged to be lowered into near proximity to said base leg of said sheave bracket, said sheave axle comprising a threaded bold fastener which is operable to tighten said locking plate in the locked position.
Claim 9
Dependent Claim
34 words
A system as claimed in claim 1 wherein said latticework of crisscrossed cables is constructed in sections with substantially all cable ends terminating at cable connector clamps at the adjoining edges of adjacent sections.
Claim 10
Dependent Claim
36 words
A system as claimed in claim 8 wherein the cable lattice sections for covering the ends of the inflatable building structure are formed with cables which are not parallel with the cables in the other sections.
Claim 11
Dependent Claim
25 words
A system as claimed in claim 1 or in claim 2 or in claim 3 wherein all intersecting cables are secured together at all intersections.
