ABSTRACT:
This invention presents a foldable cot. The foldable cot includes a foldable frame and a flexible sheet having a generally rectangular shape. The peripheral portions of the flexible sheet are secured to the foldable frame. The foldable frame has two-pairs of hingedly connected longitudinal bars, which allows the foldable frame to be folded in a longitudinal direction. A middle support structure is mounted to the hinge connectors. The middle support structure includes a pair of crossbars having a general X-shape. Upper ends of the crossbars are pivotably connected to the hinge connectors. There is provided a pair of vertical poles connecting the upper ends and lower ends of the crossbars, respectively. The vertical poles are extendible between a retracted position and an extended position, which allows the X-shaped crossbars to have a scissors-like motion so that the foldable frame can be folded in a transverse direction.
