摘要

A support which enables a roller or axle to assume either an operative or a storage position. The operative position allows the roller or axle to be rotated to result in the winding up of a flexible, sheet material attached to the roller. Once the sheet material is wound onto the roller to the extent desired, the roller is physically moved to the storage position. The storage position renders the roller immobile thus securing the sheet material from unwinding.
