Claims (1)

[Scope of utility model registration request] One horizontal stage is formed by two dividing tables, and a connecting leg part that bendably supports one end of both dividing tables is arranged directly under the separation strip where the dividing tables touch each other. By raising the connecting legs from the floor, both split tables can be folded into two, with a plurality of fixed legs at the rear lower part of one split stand and a plurality of movable legs at the front lower part of the other split stand. Both are provided at intervals in a direction parallel to the above-mentioned separation strip, and wheels are provided at the lower ends of each of the movable legs so that they continue to roll in contact with the floor surface even when the two divided tables are tilted when folded. One end of the wire is fixed to the upper part of the movable leg, and the other end of the wire is passed through the lower drive wheel of the connecting leg to a winch device disposed at the upper part of the fixed leg so that it can be wound and unwound. In the folding stage set up, a stage bag wall is fixedly erected at the rear position of the folding stage, and one horizontal stage is formed at the front position of the folding stage using one surface increasing table. In this way, the surface area increasing stage, which has wheeled movable legs provided at intervals just below the periphery of the surface increasing stage, is movably connected as an integral part by means of a connecting rod, thereby increasing the total surface area of the stage when in use. At the same time, the front position of the fixed leg part starts moving the surface increasing stage in the forward direction after the backward movement, and this movement start operation automatically moves the folding stage in the bifold state forward. A folding type surface increasing stage characterized in that a stage surface increasing auxiliary force means is installed to extend the stage.
