Abstract: In one example, a structure includes a flexible plastic body having a first end and a second end, as well as a first side and a second side disposed opposite each other. The first side includes a first group of segments, and the second side includes a second group of segments. The structure also includes a group of living hinges integral with the body, and one of the living hinges is positioned between segments, and the living hinges enable the flexible plastic body to alternatively assume a flat state, or another state in which the body is not flat.

Abstract: One example of a flexible structure includes an elongate body having a first end and a second end, and the first end is configured to be releasably connected to the second end. As well, one or more living hinges are positioned in the elongate body between the first end and the second end, and the one or more living hinges are configured and arranged to enable the first end and second end to be moved toward each other. Finally, the flexible structure is configured to alternatively assume at least a flat state and an assembled state, and in the assembled state, the first end of the elongate body is connected to the second end of the elongate body.

Abstract: A foot assembly includes a block retainer and a non-skid block. The block retainer is configured to be positioned at least proximate to an edge between a bottom surface and a side surface of a structure. The block retainer includes a planar portion, an angled portion, and a front surface. The planar portion has an interior surface configured to contact the bottom surface. The angled portion is diposed at an angle from the planar portion and includes an interior surface configured to contact an angled contact surface of the structure. The front surface includes a first dynamic coefficient of friction (DCOF). The non-skid block is connected to the planar portion and includes an exterior portion extending from the front surface away from the structure and includes a second DCOF greater than the first DCOF.
