摘要： In accordance with the present disclosure, a portable riser unit for supporting persons or objects above the ground, a floor, a stage or the like is provided. The riser broadly comprises a base, generally rectangular step members, and hinge joints for pivotally, hingedly connecting the step members to the base. The base has an integrally formed, convoluted internal or interior support and baffle wall structure and may be filled with an appropriate low density, high volume material. Each step member also may be of this construction; however, the step members may or may not have an internal support wall. The step members are operably coupled to the base by double axis hinges including hinge blocks received in complementary hinge wells in the base and step members. The hinges are self-leveling to present a substantially smooth, level riser support surface in every possible configuration. The riser may be molded of a plastic material and includes integral hand grips to facilitate moving step members or the entire riser. By manipulating the step members, the riser may be re-shaped into a variety of operable configurations. The invention also encompasses connector keys for connecting two or more risers into a riser assembly.
摘要翻译： 根据本公开，提供了一种用于支撑地面上的人或物体的便携式立管单元，地板，台架等。 提升器广泛地包括基部，大体上矩形的台阶部件和用于将台阶部件枢转地铰接地连接到基部的铰链接头。 基座具有整体形成的，卷曲的内部或内部支撑和挡板结构，并且可以填充适当的低密度大体积材料。 每一步成员也可以是这样的结构; 然而，台阶构件可以具有或不具有内部支撑壁。 台阶构件通过双轴铰链可操作地联接到基座，包括接收在底座和台阶构件中的互补铰链井中的铰链块。 铰链是自流平的，以在每个可能的构造中呈现基本平滑的液位立管支撑表面。 提升管可以由塑料材料模制，并且包括一体的手柄，以便于移动步骤构件或整个提升管。 通过操纵台阶构件，提升管可以被重新形成各种可操作的构造。 本发明还包括用于将两个或多个立管连接到立管组件中的连接器键。

摘要： A music library system that is adapted for the storage of sheet music, is designed for semi-permanent installation in a room having adjoining walls and a floor and includes a frame that is fixedly, removably coupled to the floor and to at least one wall of the room. The frame defines a plurality of drawer openings. A plurality of drawers are movably supported on the floor. Each of the plurality of drawers is disposed in a retracted disposition in close proximity to at least one other drawer in a corresponding drawer opening. The drawers are extendable from the frame outwardly from the wall to an extended disposition wherein a drawer side opening is exposed. The drawer side opening provides access to the stored sheet music.

摘要： An elevated floor has two separate types of floor panels arranged in alternating order on adjustable support legs. Base floor panels and access floor panels are formed from squares of low density oriented strand material having extruded metal cladding strips along the peripheral edges of the squares. The base floor panels include edge cladding strips having a support flange extending outwardly from the base panel peripheral edge. The access panels include a different type of cladding strip designed to seat on the support flange of the base panel cladding strip. Detachable riser beams are provided for assembly of multilevel stepped raised floors.
