Claim 6

A ground tent which comprises: a pair of collapsible subframes effective in open position to define a framework capable of supporting a wall covering when stood upon a lower edge, each of said subframes including three or more hollow rigid strut sections and a centrally-located hub-forming connector, said strut sections each being pivotally connected at one end to said connectors for hinged movement from a folded position lying alongside one another on the same side of said connectors into an unfolded position radiating from the latter in angularly-spaced relation; fastener means hingedly connecting said subframes together at points remote from said lower edges; foldable means connecting said lower edges of the subframes together so as to limit the maximum separation therebetween when unfolded; foldable sheet means covering both subframes cooperating therewith to define a wall; rings on the ends of each strut remote from said one end thereof; straps on the foldable sheet means positioned to tie onto the rings on the strut section ends forming a releasable connection therebetween; and, fastener means connecting said connector to the portion of said sheet means covering same, said fastener means, connector and sheet means cooperating to draw said sheet means into a nest defined by the strut sections when the subframe is folded inwardly.

Claim 7

A ground tent which comprises: a pair of collapsible subframes effective in open position to define a framework capable of supporting a wall covering when stood upon a lower edge, each of said subframes including three or more hollow rigid strut sections and a centrally-located hub-forming connector, said strut sections each being pivotally connected at one end to said connectors for hinged movement from a folded position lying alongside one another on the same side of said connectors into an unfolded position radiating from the latter in angularly-spaced relation; fastener means hingedly connecting said subframes together at points remote from said lower edges; foldable means connecting said lower edges of the subframes together so as to limit the maximum separation therebetween when unfolded; foldable sheet means covering both subframes cooperating therewith to define a wall; rings on the ends of each strut remote from said one end thereof; straps on the foldable sheet means positioned to tie onto the rings on the strut section ends forming a releasable connection therebetween; and, fastener means connecting said connector to the portion of said sheet means covering same, said fastener means, connector and sheet means cooperating to draw said sheet means into a nest defined by the strut sections when the subframe is folded inwardly.

Claim 8

The ground tent as set forth in claim 3 in which: the slots include a wide section sized to pass the enlargements on the ends of the cord and a relatively narrower section sized to pass said cord while blocking the passage of said enlargement.

Claim 9

The ground tent as set forth in claim 3 in which: rings are provided in the slotted ends of the strut sections positioned to block the removal of the cord ends therefrom; and, in which a pin is detachably fastened to said slotted strut end in position to provent removal of said ring from the slots.

Claim 10

A tent frame comprising in combination: a pair of collapsible subframes effective in open position to define a framework capable of supporting a wall covering when stood upon a lower edge, each of said subframes including three or more rigid strut sections and a centrally-located hub-forming connector, said strut sections each being pivotally connected at one end to said connector for hinged movement from a folded position lying alongside one another on the same side of said connector into an unfolded position radiating from the latter in angularly-spaced relation; fastener means hingedly connecting said subframes together at points remote from said lower edges; and, sheet fabric means connecting said lower edges of the subframes together so as to limit the maximum separation therebetween when unfolded, said sheet means also cooperating with the fastener means and with said subframes in open position to define a free-standing structure, and said sheet means further cooperating with said subframes in collapsed condition to envelop same and form a protective covering therefor.
