Abstract

Abstract Framework for a portable shelter comprising pivotally struts being movable between an expanded condition and a collapsed condition. In the expanded condition the framework comprises a network of three dimensional modules. Some of the modules form an upper portion of the frame work and some of them form a plurality of strings of modules extending from the upper portion downwardly. Each module defines a separate arch portion.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 151 words
A framework for a portable shelter, said framework com­prising a plurality of pivotally interconnected elongate struts capable of relative movement between an expanded condition defining a network of modules forming a three dimensional framework and a collapsed condition defining bundled struts, each module being of three dimensional form when the framework is expanded and each module including opposite ends each formed by a pair of crossed, pivotally connected struts and opposite sides each formed by a pair of crossed, pivotally connected struts, and hub means pivotally joining adjacent ends of said pairs of struts, characterized in that when the framework is expanded, some of said modules form an upper portion of the framework and some of said modules form a plurality of strings of modules extending downwardly from the upper portion of the framework, each string of modules defining a separate arch portion for supporting the upper portion in elevated position.
Claim 2
Dependent Claim 151 words
A framework for a portable shelter, said framework com­prising a plurality of pivotally interconnected elongate struts capable of relative movement between an expanded condition defining a network of modules forming a three dimensional framework and a collapsed condition defining bundled struts, each module being of three dimensional form when the framework is expanded and each module including opposite ends each formed by a pair of crossed, pivotally connected struts and opposite sides each formed by a pair of crossed, pivotally connected struts, and hub means pivotally joining adjacent ends of said pairs of struts, characterized in that when the framework is expanded, some of said modules form an upper portion of the framework and some of said modules form a plurality of strings of modules extending downwardly from the upper portion of the framework, each string of modules defining a separate arch portion for supporting the upper portion in elevated position.
Claim 3
Dependent Claim 29 words
A framework as defined in claim 1 wherein the upper portion is square or rectangular and adjacent arch portions define separa­tions therebetween at the corners of the upper portion.
Claim 4
Dependent Claim 131 words
A framework for a portable shelter as defined in claims 1 or 2 wherein modules of a first set of said modules are bounded by opposite sides and opposite ends in which the crossed, pivoted pairs of struts defining such sides and ends are symmetrically crossed and pivoted and modules of a second set of said modules are bounded by opposite sides and opposite ends in which the opposite sides of the modules of said second set are defined by pairs of struts which are asymmetrically crossed and pivoted and in which the opposite ends of the modules of said second set are defined by pairs of struts which are symmetrically crossed and pivoted, each arch portion being formed of a mixture of modules of said first and second sets there­of.
Claim 5
Dependent Claim 21 words
A framework for a portable shelter as defined in claims 1-3 wherein all of said struts are of the same length.
Claim 6
Dependent Claim 26 words
A framework for a portable shelter as defined in claims 1-4 wherein said upper portion is provided on all sides with at least one arch portion.
Claim 7
Dependent Claim 20 words
In a collapsible/expandable framework as defined in claims 1-5 including flexible material joined to said framework in covering relation thereto.
Claim 8
Dependent Claim 42 words
In a collapsible/expandable framework as defined in claims 1-6 wherein certain of said modules when expanded present inner and outer faces which are square and other of said modules when expanded present inner and outer faces which are of different rectangular areas.
Claim 9
Dependent Claim 64 words
In a collapsible/expandable framework as defined in claims 1-7 wherein at least one of said arch portions is defined by a first sequence of said modules arching downwardly from said upper portion adjacent a corner thereof and a second sequence of said modules joined along a vertically extending edge of said first sequence of modules in alignment with a corner of said top region.
Claim 10
Dependent Claim 48 words
In a collapsible/expandable framework as defined in claims 1-8 wherein another of said arch portions is defined by a third sequence of said modules arching downwardly from said top region adjacent said corner thereof, and means separably joining said third sequence to said further sequence in side-by-side relation.
Claim 11
Dependent Claim 51 words
In a collapsible/expandable framework as defined in claims 1-9 wherein at least one arch portion is located in bridging rela­tion to one corner of the upper portion to define a triangular module at such corner, and including means for separably joining an apex of said triangular module to an adjacent module.
