Abstract: A control system guides and supports the deployment of a folded, collapsed bleacher system. The control system includes a hydraulic device implemented as a piston-cylinder combination anchored at one end to the trailer frame carrying the stowed bleacher and anchored at another end to an undercarriage support member of the bleacher. The movement of the piston exerts a tandem pivoting action on the front and rear bleacher sections, which deploys and opens the bleacher system to a level, seating-ready configuration. A weight detection module senses the approach of a free-fall condition of the bleacher system during deployment and increases the applied resistance of the piston-cylinder combination, controlling the rate of descent of the bleacher system to avoid free-fall.

Abstract: A telescopic seating system generally includes an innermost lower riser assembly and successive outer elevated riser assemblies. Each elevated riser assembly includes a dual deck surface and a telescopic leg assembly. Each elevated riser assembly supports a toothed belt drive system which provides the interface between each adjacent elevated riser assembly and the motive force to extend and retract the riser system. In operation, electric motors of the toothed belt drive system on each elevated riser assembly are driven by a controller to extend and retract the telescopic seating system between a fully extended position, a half-deployed position and a storage position. The half-deployed position utilizes the dual deck surface to provide half the seating capacity of each riser at twice the rise between each seating row to thereby accommodate particular venues.
