Patent ID: 8296999

Claim:
A bleacher system, comprising: a support structure mounted on wheels; an upper tier and a second tier mounted on the support structure, with the upper tier being connected to the second tier by a pin connection defining a pivot point, and each tier including multiple girders at spaced intervals that are operably connected to the support structure, each girder supporting a plurality of seat supports and a plurality of foot board supports, with seat planks then secured to the seat supports and foot planks secured to the foot board supports in each tier; and at least one actuator operably connected to and extending between the support structure and the second tier, with the extension of the rod of the actuator causing the second tier to pivot about a pivot point relative to the support structure in a first direction, while causing the upper tier to pivot about a pivot point relative to the second tier in an opposite direction, such that the upper tier and the second tier move away from one another during the transition from a transport position into a deployed position; wherein, in the transport position, each girder of each tier is in an upright orientation relative to the support structure.
