    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： A portable stepped riser unit for supporting persons or items above a floor, a stage or the like is provided. The riser unit is foldable for transport and storage. It includes a generally tubular support frame, a plurality of platforms for forming the steps removably mounted on the support frame, and a lockable telescoping brace assembly associated with the support frame. The brace assembly includes a foot operated lock, whereby a single operator may fold, move and erect the riser unit.

    摘要： A portable podium and performance platform system includes one or more platform sections that may be assembled together to provide one or more relatively small elevated surfaces having a horizontal orientation on which an individual or small group of individuals may stand or be seated so as to enhance communication and visibility. At least one of the platform sections includes an integral transport assembly for transporting the platform sections in a vertical orientation. The transport assembly comprises two or more wheels which are mounted on an axis of rotation that is transverse to the platform surface and positioned to allow at least an arcuate section of the wheels to extend beyond a peripheral edge of the platform surface. The podium and performance platform system may be transported to a desired location by tipping the platform sections into the vertical orientation and up onto the arcuate section of the wheels of the transport assembly, rolling the platform sections to the desired location, and then tipping the platform sections back down into the horizontal orientation.
