Abstract: An improved roller device includes a plurality of segments, wherein the plurality of segments is configured to form a tubular shape. In addition each of the plurality of segments are coupled to neighboring segments of the plurality of segments and each of the plurality of segments include a first edge and a second edge, wherein the first edge is opposite the second edge. Each segment includes a plurality of protrusions on each respective edge for interfacing with a respective complementary edge with complementary protrusions of a neighboring segment. The roller device also includes a coupling mechanism for coupling the first edge of a segment to a second edge of a first neighboring segment and coupling the second edge of the segment to a first edge of a second neighboring segment, wherein the coupling mechanism allows the plurality of segments to convert from a first position to a second position.

Abstract: A playground system has an enclosure that defines a play area and an entry point. A transfer system couples with the entry point of the enclosure. A modular playground is positioned within the enclosure to exclude the playground system from compliance with accessibility standards. The modular playground has a plurality of base members arranged within the enclosure, a play unit positioned on each base member, and an securement member engaged with the base member, the play unit, and the enclosure for securement in a customized arrangement.
