Abstract
Abstract Apparatus for use both as a platform for drum-set performances and as a carrier for such a set. The apparatus consists of a rectangular bottom section with two or more side members hinged thereto for raising to a vertical position or lowering to a horizontal position. Castors are attached to at least two of such side members so that when they are raised, the castors extend downward from the bottom section, and when lowered, the castors are retracted above the bottom section. With the side members raised, the drum-set can be placed upon the bottom section, and the entire unit rolled, or carried by provided handles. With the side members lowered, the drum-set can be placed upon the bottom section and side members, and the apparatus used as a performance platform.
