ABSTRACT:
A portable bleacher including a mobile frame supporting a pair of hinged elongated stringer members, each stringer member carrying a plurality of seats. When the stringer members are pivotally swung to their operative position in which the stringer members are aligned and declining transversely of the mobile frame, the seats are also spaced along the stringer members in a declining attitude. When the stringer members are swung to their inoperative positions, the hinged joint between the stringer members is elevated so that the stringer members have an inverted V-shaped configuration supported on the mobile frame and contained between the side edges of the frame for over-the-road movement. The bleacher may also be provided with extensible and collapsible side rails which move with the stringer members.
