发明名称 Telescopic risers
摘要 A telescopic multi-tier riser assembly formed from a plurality of telescopic multi-tier riser modules positioned in side-by-side relationship. Each said riser module is of a telescopic multi-tier construction and includes top and bottom platforms and at least one intermediate platform. The platforms are telescopically movable relative to one another between an open position wherein the individual platforms project forwardly in a step-like manner and a closed position wherein the platforms are vertically supported one above the other. The platforms each have a side-to-side width which is substantially less than its front-to-back length, which width comfortably accommodates only a single chair on the respective platform. A modesty panel assembly is preferably hingedly supported on each platform adjacent the forward edge thereof and swingably movable relative to the respective platform between an upright use position and a horizontal storage position wherein the modesty panel assembly is supported on the upper surface of the respective platform.
