Abstract
To assure that each spectator sitting on his seat enjoys a performance in a theater or the like at his desired height, a floor height adjusting mechanism is mounted on each of a plurality of movable platforms constituting a variable floor height telescopic multi-staged spectator seating system. Usually, the floor height adjusting mechanism is constructed in the form of a threaded shaft driving unit which is composed of a motor, a threaded shaft adapted to be rotationally driven by the motor, and a support column fixedly secured to each movable platform. The lowermost end of the support column is operatively connected to the lowermost end of the threaded shaft for rotatably holding the threaded shaft. Otherwise, the floor height adjusting mechanism is constructed in the form of a combination of a threaded shaft driving unit with a moving pulley unit, and this type of floor height adjusting mechanism is preferably employable for a lowermost movable platform which requires that an adjustable height can be increased.
