  • Patent number: 6474024
    Abstract: The seating section of a seating system is variable in slope between high riser and low riser positions forward ends of the pivotable treads forming a deck surface overlap confronting ends of adjacent treads, and lever arms maintain the treads substantially level irrespective of inclination of the underlying support beams. The arms are pivotable between angular and upright positions and extend between each of the treads and the beams. The forward ends of the treads are supported on support plates mounted on the support beams in a low riser height position of the seating section, and the lever arms support the forward ends of the treads on the support plates in a high riser position of the seating section.

  • Patent number: 6003270
    Abstract: A seating system having a plurality of seating sections in which the slope of the understructure thereof can be varied, the treads of the seating sections being pivotable to permit the riser height to vary so as to enable a single seating system to provide varying slopes and sight lines depending on the stadium/arena configuration. The treads are pivotable between low riser and high riser positions by the provision of lever arms movable between angular and upright positions and extending between the treads and the beams for supporting the treads in the high riser position on the upper surface of understructure beams. In the low riser position ends of the treads opposite their pivotal ends are supported on an adjacent tread.

  • Patent number: 5660000
    Abstract: A movable two-fold seating assembly includes an upright support structure, a forward seating section pivoted to the support structure, and a rearward seating section pivoted to the structure. Forward and rearward frame structures are pivoted to the free ends of the seating sections for supporting the same on the ground. The frame structures are folded to underlie their respective seating sections, and the seating sections are folded about opposing sides of the upright support structure. The entire seating assembly is transportable in the folded condition by lowering ground engaging wheels to the ground from a base structure of the upright support, and lifting the forward end of the assembly as by a forklift.

  • Patent number: 5379556
    Abstract: A folding grandstand comprising a supporting frame of forward intermediate and rearward sections hinged together at adjacent ends, vertical support assemblies hinged to the respective sections for supporting the sections on a ground tracks and permitting the grandstand sections to be folded into a collapsed position. The support assemblies comprise continuous trusses permitting the use of fewer pickup points when folding the grandstand along the tracks.
