Abstract
Abstract Three-dimensional collapsible structure having the form of a system of bars articulated to one another, which comprises a twodimensional lattice made of parallelograms of hinged bars, acting as a first carrier element, a second carrier element which has preferably the same construction as the first one and a number of pivoting rods connecting together some of the joints of the two carrier elements, said rods being inclined with respect to the planes of the carrier elements when the structure is deployed.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
190 words
A three-dimensional collapsible structure comprising in combination at least one pair of spaced apart generally parallel two-dimensional lattice assemblies each comprised of straight bars arranged in X-shaped pairs articulated together at their intersections, each X-Shaped pair of bars in each such lattice, exclusive of those on the periphery of the structure, having each of the four ends thereof pivotally connected to the end of at least one adjacent X-shaped pair of bars, all such articulations and pivotal connections of each assembly being fitted on axes perpendicular to the general plane of that assembly, the assemblies of each adjacent pair of such assemblies being displaced laterallY relative to one another so that a straight line passing through any axis of articulation of said bar pairs in such assemblies extends at an oblique angle to the general planes of said assemblies, and connecting rods between such assemblies, each rod having its respective ends pivotally connected on axes inclined with respect to the general plane of the corresponding assembly to the pivotally connected ends of two adjacent bar pairs in the same assembly and extending obliquely to the general planes of the assemblies.
Claim 2
Dependent Claim
190 words
A three-dimensional collapsible structure comprising in combination at least one pair of spaced apart generally parallel two-dimensional lattice assemblies each comprised of straight bars arranged in X-shaped pairs articulated together at their intersections, each X-Shaped pair of bars in each such lattice, exclusive of those on the periphery of the structure, having each of the four ends thereof pivotally connected to the end of at least one adjacent X-shaped pair of bars, all such articulations and pivotal connections of each assembly being fitted on axes perpendicular to the general plane of that assembly, the assemblies of each adjacent pair of such assemblies being displaced laterallY relative to one another so that a straight line passing through any axis of articulation of said bar pairs in such assemblies extends at an oblique angle to the general planes of said assemblies, and connecting rods between such assemblies, each rod having its respective ends pivotally connected on axes inclined with respect to the general plane of the corresponding assembly to the pivotally connected ends of two adjacent bar pairs in the same assembly and extending obliquely to the general planes of the assemblies.
Claim 3
Dependent Claim
55 words
The structure of claim 1 wherein the assemblies of each adjacent pair of assemblies are displaced laterally so that a perpendicular line drawn through each such articulation or pivotal connection in one assembly passes through a point approximately equidistant from two adjacent articulations or pivotal connections in the other assembly of such pair of assemblies.
Claim 4
Dependent Claim
31 words
The structure of claim 1 wherein each of the pivotally connected two ends of two adjacent bar pairs are connected on said inclined axes to two generally oppositely extending connecting rods.
Claim 5
Dependent Claim
19 words
The structure of claim 1 wherein said connecting rods extend obliquely between said lattice assemblies in generally zig-zag fashion.
Claim 6
Dependent Claim
29 words
The structure of claim 1 wherein pairs of said connecting rods are articulated together intermediate their ends to form X-Shaped pairs of such rods intervening between said lattice assemblies.
Claim 7
Dependent Claim
51 words
The structure of claim 1 wherein the X-shaped pairs of connecting rods corresponding to one row of said X-shaped bar pairs in said assemblies are inclined in one oblique direction while the rod pairs corresponding to the next adjacent row of bar pairs are inclined in a generally opposite oblique direction.
Claim 8
Dependent Claim
22 words
The structure of claim 1 wherein the X-shaped rod pairs are inclined in alternating directions in each row of said bar pairs.
Claim 9
Dependent Claim
31 words
The structure of claim 1 wherein each of the pivotally connected two ends of two adjacent bar pairs are connected on said inclined axes to four generally oppositely extending connecting rods.
Claim 10
Dependent Claim
29 words
The structure of claim 1 wherein the ends of said bar pairs and said connecting rods are connected by rings which provide both said perpendicular and said inclined axes.
Claim 11
Dependent Claim
24 words
The structure of claim 1 further comprising rigid multi-legged joint elements to constitute the intersection between said inclined and perpendicular axes of pivotal connection.
