Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
242 words
A collapsible module comprising an upper and lower member provided in an opposite relationship to each other, each of said members comprising an equilateral polygon base plate or frame, a plurality of side frames or plates, of the same number as the number of sides of said polygon hingedly connected at their proximal end to said base plate or frame, the distal end of said side frames being hingedly connected to the distal end of the side frames or plates of the other member, wherein the sides of said side frames taper inwardly from said base plate or frame to give a trapezoidal configuration to each of said side frame or plates, the center of the hinge of the proximal side coinciding with the center of the hinge at the distal side of the same side plate or frame and the center of the proximal side of a side plate of one member coinciding with the center of the proximal side of the side plate of the other member to which it is hinged, such that in an erect position the side plates of each member are disposed inwardly to the vertical axis of said module and the two sides of one side plate of any one member is in side contact with the adjoining side plates of the same member, and such that in the collapsed position said side plates or frames lie outwardly of their respective base plate or frame.
Claim 2
Dependent Claim
242 words
A collapsible module comprising an upper and lower member provided in an opposite relationship to each other, each of said members comprising an equilateral polygon base plate or frame, a plurality of side frames or plates, of the same number as the number of sides of said polygon hingedly connected at their proximal end to said base plate or frame, the distal end of said side frames being hingedly connected to the distal end of the side frames or plates of the other member, wherein the sides of said side frames taper inwardly from said base plate or frame to give a trapezoidal configuration to each of said side frame or plates, the center of the hinge of the proximal side coinciding with the center of the hinge at the distal side of the same side plate or frame and the center of the proximal side of a side plate of one member coinciding with the center of the proximal side of the side plate of the other member to which it is hinged, such that in an erect position the side plates of each member are disposed inwardly to the vertical axis of said module and the two sides of one side plate of any one member is in side contact with the adjoining side plates of the same member, and such that in the collapsed position said side plates or frames lie outwardly of their respective base plate or frame.
Claim 3
Dependent Claim
57 words
A collapsible module as claimed in claim 1 wherein and when the module is in an erect position, the centers of the proximal and distal sides of any two side plates hinged to each other lies along the same vertical plane, but wherein the centers of the proximal sides and distal sides lie along different vertical lines.
Claim 4
Dependent Claim
49 words
A collapsible module as claimed in claim 1 wherein the line passing through the center of the proximal and distal sides of each side plate of each member coincides with the center of the base plate or frame of that member, when the module is in a collapsed position.
Claim 5
Dependent Claim
37 words
A collapsible column comprising a plurality of said collapsible modules of claim 1 wherein the base plate or frame of one of said collapsible module coincides with the base plate or frame of the adjacent collapsible module.
Claim 6
Dependent Claim
31 words
A collapsible column as claimed in claim 4 wherein the base frame of the upper member of one module forms the base frame of the lower member of the adjacent module.
Claim 7
Dependent Claim
181 words
A collapsible module comprising an upper and lower member provided in an opposite relationship to each other, each of said members comprising a base plate or frame, a plurality of side frames or plates hingedly connected at their proximal end to said base plate or frame, the distal end of said side frames or plates of the lower member being hingedly connected to the distal end of the side frames or plates of the upper member, wherein the sides of said side frames or plates taper inwardly from said base plate or frame and wherein the two sides of one side plate or frame of any one member is in complete or partial side contact with the adjoining side plates or frames of the same member, when the module is in an erect position, and further such that in said erect and locked position the side plates or frames of each member are disposed inwardly to the vertical axis of said module and in the collapsed position the side plates or frames lie outwardly of their respective base plate or frame.
Claim 8
Dependent Claim
181 words
A collapsible module comprising an upper and lower member provided in an opposite relationship to each other, each of said members comprising a base plate or frame, a plurality of side frames or plates hingedly connected at their proximal end to said base plate or frame, the distal end of said side frames or plates of the lower member being hingedly connected to the distal end of the side frames or plates of the upper member, wherein the sides of said side frames or plates taper inwardly from said base plate or frame and wherein the two sides of one side plate or frame of any one member is in complete or partial side contact with the adjoining side plates or frames of the same member, when the module is in an erect position, and further such that in said erect and locked position the side plates or frames of each member are disposed inwardly to the vertical axis of said module and in the collapsed position the side plates or frames lie outwardly of their respective base plate or frame.
Claim 9
Dependent Claim
36 words
A collapsible module as claimed in claim 6 wherein the center of the hinge at the proximal end coincides with the center of the hinge at the distal end of the same side plate or frame.
Claim 10
Dependent Claim
49 words
A collapsible module as claimed in claim 7 wherein the line passing through the center of the proximal and distal ends of each side plate of each member coincides with the center of the base plate or frame of that member, when the module is in a collapsed position.
Claim 11
Dependent Claim
31 words
A collapsible column as claimed in claim 8 wherein the base frame of the upper member of one module forms the base frame of the lower member of the adjacent module.
Claim 12
Dependent Claim
51 words
A collapsible module as claimed in claim 6 wherein the center of the proximal end of a side plate or frame of one member coincides with the center of the proximal end of the side plate or frame of the other member to which it is hinged to constitute a module.
Claim 13
Dependent Claim
57 words
A collapsible module as claimed in claim 6 wherein and when the module is in an erect position, the centers of the proximal and distal end of any two side plates hinged to each other lies along the same vertical plane, but wherein the centers of the proximal end and distal end lie along different vertical lines.
Claim 14
Dependent Claim
205 words
A collapsible frame comprising a plurality of collapsible modules and wherein adjacent modules are hingedly connected to each other, each of said collapsible modules comprising a lower member and an upper member being provided in an opposite relationship to each other, each of said members comprising a base plate or frame, a plurality of side frames or plates hingedly connected at their proximal end to said base plate or frame, the distal end of said side frames or plates of the lower member being hingedly connected to the distal end of the side frames or plates of the upper member, wherein the sides of said side frames or plates taper inwardly from said base plate or frame and wherein the two sides of one side plate or frame of any one member is in complete or partial side contact with the adjoining side plates or frames of the same member, when the module is in an erect position, and further such that in said erect and locked position the side plates or frames, or each member are disposed inwardly to the vertical axis of said module and in the collapsed position the side plates or frames lie outwardly of their respective base plate or frame.
