Abstract: A railing system for a telescopic seating arrangement, such as bleacher systems and platform seating systems. The railing system includes discrete lightweight and readily stowable uprights, each having a single closed-loop upper section. Brackets carried by the nose of decks receive a plate affixed to the lower end of each upright. The brackets which support the uprights have a low profile so that the seating system is readily useable if the uprights are not installed. The lightweight and easily stowed uprights of this railing system eliminate the factors which lead to use of a seating system without handrails.

Abstract: A guard rail scaffold assembly comprises a plurality of assembly members carrying horizontally extending guard rails. Each assembly member comprises an elongated base member attachable by a releasable connector to a fastener pad fastened to an above-ground structure surface. The connector allows pivoting movement of the base member for adjustment of the base member to be parallel to the surface. The base member also carries surface engaging members on opposite sides of the connector which engage the structure surface to maintain the base member parallel to the structure surface. A first post member extends from the base member and, when the scaffold is mounted on the guarded surface, this constitutes a guard rail support member or has a guard rail support member mounted thereon. When the scaffold is mounted on a wall surface a second post member is releasibly mounted on the first post member and receives the guard rail support member instead of the first post member.

Abstract: This invention relates to apparatus used in supporting safety rails and discloses a system in which a safety rail post support and security device is used in pairs or greater multiples to hold pieces of a safety rail at the edge of an elevated surface and is speedily attached to or detached from the three commonly found roof edge structures, that is, roofs that are flat right up to the edge, roofs that have a very low ledge or flashing around the perimeter, and roofs that have a parapet along the edge. Previous systems rely on cantilever weights positioned well in from the edge of the roof, interfering with the work to be done there. The post support and security device has a junction piece comprising four intersecting extruded stabilizer bars perpendicular to each other in one plane and a fifth bar protruding from that plane at ninety degrees. An upright post fits into one of the bars after the junction piece is bolted to a roof or to a wall abutting the edge of a roof, or is clamped to a parapet.
