the at least one of the plurality of hinges comprises: a first pin provided between the edge of the first panel of the first row of panels and the edge of the first panel of the second row of panels; a first strip that connects from the first pin to the first panel of the first row of panels; a second strip that connects from the first pin to the first panel of the second row of panels. ### Claim 10 (depends on 1) The collapsible structure of claim 1, wherein: the at least one of the plurality of hinges comprises: a first plate, wherein the first plate is connected to the first panel of the first row of panels; a second plate, wherein the second plate is connected to the first panel of the second row of panels; a first arm coupled between the first plate and the second plate so as to turn the first plate; a second arm coupled between the first plate and the second plate so as to turn the second plate; wherein the first arm and the second arm are configured so that the first plate and the second plate face one another in a folded position and are on substantially a same plane in an unfolded position. ### Claim 11 (depends on 1) The collapsible structure of claim 1, wherein: the at least one of the plurality of hinges comprises: a first plate, wherein the first plate is connected to the first panel of the first row of panels; a second plate, wherein the second plate is connected to the first panel of the second row of panels; a first arm coupled between the first plate and the second plate so as to turn the first plate between a folded position and an unfolded position, the first arm defining a first length wherein the first arm is bent so that the first length extends further in a first direction when the first plate is in the unfolded position than when the first plate is in the folded position. ### Claim 12 (depends on 1) The collapsible structure of claim 1, wherein the collapsible structure may be transitioned from the collapsed state to the erected state while the plurality of panels remain connected by the plurality of hinges. ### Claim 13 (depends on 1) The collapsible structure of claim 1, wherein the collapsible structure may be transitioned from the erected state to the collapsed state while the plurality of panels remain connected by the plurality of hinges. ### Claim 14 (depends on 1) The collapsible structure of claim 1, wherein dimensions of the first panel of the second row of panels mirror dimensions of the first panel of the first row of panels. ### Claim 15 (depends on 1) The collapsible structure of claim 1, wherein in the collapsed state, the first panel of the first row of panels and first panel of the second row of panels are positioned on outermost sides of first stack. ### Claim 16 A collapsible structure, comprising: a plurality of hinges; a plurality of panels that are swingably connected by the plurality of hinges, wherein the plurality of panels are arranged so as to collapse the plurality of panels into at least one stack in a collapsed state and so as to form a shelter in the erected state; wherein each panel of the plurality of panels defines a pair of connection edges such that the pair of connection edges are non-parallel, and wherein the plurality of panels form layers of the at least one stack, wherein the layers alternate between a layer comprising a panel of a first row of panels and a layer comprising a panel of a second row of panels; and wherein the at least one of the plurality of hinges directly connects a first panel of the first row of panels to a first panel of the second row of panels, wherein in the erected state, the at least one of the plurality of hinges is configured to position a first connection edge of the first panel of the first row of panels colinearly with a first connection edge of the first panel of the second row of panels, and wherein in the collapsed position, the first connection edge of the first panel of the first row of panels is spaced apart from the first connection edge of the first panel of the second row of panels. ### Claim 17 A collapsible structure, comprising: a plurality of hinges;
