Abstract
Abstract This invention relates to a collapsible tent structure in which both sidewalls, the rear wall and top are supported by nearly identical subframe assemblies, each of which has a length of stretchable cord fastening the ends of its jointed diagonally extending struts together. The struts of each subframe assembly are pivotally attached at their adjacent ends to a stop-forming connector at the intersection of the diagonals for foldable movement in one direction into side-by-side relation with one another while such connector limits their unfolded position to one in which they bear an angular relation of over 180* and less than approximately 220* to one another which position is maintained by the tension in the stretchable cord interconnecting the remote ends thereof. The cord preferably is reeved through marginal hems bordering the frame-supported walls thus defining a unitary foldable tent assembly. The frame itself comprises the four more or less identically constructed subframe assemblies pivotally interconnected to one another at their common corners together with the connectors for accomplishing the latter.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
212 words
The tent which comprises: at least four collapsible subframe assemblies pivotally interconnected at their common corners to define a roof frame bounded on at least three sides by upstanding wall frames, each of said subframes including a pair of diagonally extending inwardly folding jointed struts arranged in crossed relation, stop forming connector means located at the intersection of each strut pair hingedly interconnecting the jointed sections thereof together for limited relative pivotal movement between an inwardly folded one and a fully unfolded position wherein the sections of each strut bear an angular relationship to one another that exceeds 180* and is less than approximately 220*, and means comprising a stretchable cord tensioned between the remote ends of adjacent strut sections in the same subframe, said cord defining a continuous generally rectangular loop therearound adapted to cooperate with the stop forming connector at the intersection thereof to releasably maintain same in fully unfolded position; and, a foldable fabric defining a covering for at least one of the subframes, said covering having the marginal areas thEreof provided with loopforming elements positioned and adapted to receive and retain the lengths of tensioned cord extending between the ends of the subframe strut sections thus producing a unitary assembly with the collapsible frame defined by the subframes.
Claim 2
Dependent Claim
212 words
The tent which comprises: at least four collapsible subframe assemblies pivotally interconnected at their common corners to define a roof frame bounded on at least three sides by upstanding wall frames, each of said subframes including a pair of diagonally extending inwardly folding jointed struts arranged in crossed relation, stop forming connector means located at the intersection of each strut pair hingedly interconnecting the jointed sections thereof together for limited relative pivotal movement between an inwardly folded one and a fully unfolded position wherein the sections of each strut bear an angular relationship to one another that exceeds 180* and is less than approximately 220*, and means comprising a stretchable cord tensioned between the remote ends of adjacent strut sections in the same subframe, said cord defining a continuous generally rectangular loop therearound adapted to cooperate with the stop forming connector at the intersection thereof to releasably maintain same in fully unfolded position; and, a foldable fabric defining a covering for at least one of the subframes, said covering having the marginal areas thEreof provided with loopforming elements positioned and adapted to receive and retain the lengths of tensioned cord extending between the ends of the subframe strut sections thus producing a unitary assembly with the collapsible frame defined by the subframes.
Claim 3
Dependent Claim
92 words
The tent as set forth in claim 1 in which: the stop forming connector means comprises a plate with intersecting channels formed in one face thereof, each such channel having a transversely extending pin in the mouth thereof adjacent the intersection adapted to pivotally mount the inner end of a strut section and an upstanding stop spaced radially outward from said pin, said stop and pin cooperating with one another and the like elements in the channel aligned therewith to maintain the sections of the strut fastened therein in fully extended position.
Claim 4
Dependent Claim
48 words
The tent as set forth in claim 1 in which: the front of the tent is left without a subframe; and, in which the covering extends over the top and down all four sides, that portion of the covering on the front being slit to define an entryway.
Claim 5
Dependent Claim
28 words
The tent as set forth in claim 1 in which: the stop forming connector means holds the strut sections at an angle of approximately 200* when fully extended.
Claim 6
Dependent Claim
38 words
The tent as set forth in claim 1 in which: the loop forming elements in the marginal areas of the covering comprise a double thickness of fabric stitched to define a tunnel-like passage sized to receive the cord.
Claim 7
Dependent Claim
47 words
The tent as set forth in claim 1 in which: the remote ends of adjacent strut sections in the roof frame are spaced apart the same distance as the corresponding remote strut section ends of the wall frames with which they pivotally connect at the common corners.
Claim 8
Dependent Claim
36 words
The tent as set forth in claim 1 in which: the covering includes skirt forming flaps along the bottom edge thereof adapted to lay out upon the ground and provide means for anchoring the tent down.
