Claim:
A foldable cot comprising: a foldable frame having a folded position and an unfolded position; and a flexible sheet having a generally rectangular shape, said flexible sheet having peripheral portions secured to said foldable frame; said foldable frame comprising: a first longitudinal bar and a second longitudinal bar hingedly connected with each other via a first middle hinge connector; a third longitudinal bar and a fourth longitudinal bar hingedly connected with each other via a second middle hinge connector; a middle support structure mounted to said first and second middle hinge connectors; a first leg pivotably attached to said first longitudinal bar; a second leg pivotably attached to said second longitudinal bar; a third leg pivotably attached to said third longitudinal bar; and a fourth leg pivotably attached to said fourth longitudinal bar wherein said middle support structure comprises a first crossbar and a second crossbar together forming a general X-shape when said foldable frame is in said unfolded position, and wherein an upper end of said first and second crossbars are pivotably connected to said first and second middle hinge connectors, respectively; wherein said middle support structure further comprises a first vertical pole and a second vertical pole each having a top end attached to said first and second middle hinge connectors, respectively, and wherein a lower end of said first and second crossbars are pivotably connected to a bottom end of said first and second vertical poles, respectively; wherein said first and second vertical poles are extendible between a retracted position and an extended position, wherein said first and second vertical poles are in said retracted position when said foldable frame is in said unfolded position, and wherein said first and second vertical poles are in said extended position when said foldable frame is in said folded position; wherein said first, second, third, and fourth legs are pivotably connected to said first, second, third, and fourth longitudinal bars, respectively, via leg hinge brackets such that said leg hinge brackets allow said legs to pivot between a folded position and an unfolded position, said unfolded position and folded position defining therebetween an angle substantially larger than 90° but substantially less than 180°; and wherein said first, second, third, and fourth legs are pivotable relative to their respective longitudinal bars independently of one another.
