摘要： A miniature roll-up halfpipe for use with fingerboards or miniature skateboards includes a pair of sideframes configurable in either a collapsed compact configuration or an extended open configuration. A pair of platforms join the end portions of the sideframes to form a generally rectangular structure having a pair of upwardly open curved edges. A flexible resilient sheet is received upon the supporting frame to form a curved surface of the type frequently used by skateboarder's or the like. In the closed configuration, the flexible sheet is rolled into a cylindrical shape and encloses the collapsed siderails and platform elements. A pair of generally cylindrical endcaps are received upon the opposed ends of the rolled sheet to provide closure and secure attachment thereof.
