ABSTRACT:
Two different types of electrically-operated folding stage systems, namely a high-type system and a low-type system are provided. Each type of system includes a pair of opposed stage components. The high-type system may include an additional pair or pairs of stage components. The opposed stage components are pivotally connected together. Each stage component includes a platform. In the high-type system, a plurality of rows of brackets are fixed to the bottom of the platform. A downwardly-extending upright leg is pivotally connected to the lower end of each bracket to support the entire system on a support such as a floor. Casters may be connected to the lower ends of at least the foremost and rearmost legs of each row to enable the entire system to be moved in a desired horizontal direction on the floor. A pair of opposed geared motors are mounted on the bottom of the platform of at least one of the opposed stage components. A pair of opposed link mechanisms are connected to the motors, respectively. When the motors are rotated in one direction, the link mechanisms make articulating movements from substantially horizontal positions to substantially vertical opposed positions, thereby folding the entire opposed stage components. When the motors are rotated in the opposed direction, the link mechanisms make articulating movements from the vertical positions to the horizontal positions, thereby unfolding the stage components.
