Claims (1)

[Claims for Utility Model Registration] (1) A front stage unit and a rear stage unit each consisting of a dividing table for two units are formed so that they can be folded into two by moving the position between the units on each side, Both of the stage units are connected to each other so that they can be moved by expansion and contraction at both adjacent ends, and both of the stage units are operated by tensioning and loosening the wires to select between segmental expansion and contraction for each unit and continuous expansion and contraction. This is a connected type folding stage that is characterized in that it is performed automatically and automatically. (2) The connecting type folding stage according to claim 1, wherein a folding bracket and a wire push-down leg are provided in the intermediate zone of each stage unit. (3) The apparatus according to claim 1, wherein movable legs are provided at the front and rear ends of the front stage unit and at the front end of the rear stage unit, and the movable legs located at adjacent ends of both are connected by upper and lower connecting plates. Connected type folding stage. (4) The connected type folding stage according to claim 1, wherein a drive source for tensioning and loosening the wire is installed on at least one of the stage units. (5) The connected type folding stage according to claim 1, wherein the heights of both stage units when extended in series are varied so that there is a step on both stage surfaces. (6) Form two sets of both stage units, and
2. A connected type folding stage according to claim 1, wherein both stage units of the set are arranged facing each other with the left and right stage side walls facing each other, and when both stage units are fully extended, they form a series of stage surfaces. (7) The connecting type folding stage according to claim 2, wherein the folding bracket includes an elastic restoring device. (8) The connecting type folding stage according to claim 2, wherein a driving wheel is provided at the lower end of the wire push-down leg. (9) A fixed leg portion is provided at the end of the stage unit adjacent to the stage back wall or the left and right stage side walls, and the fixed leg portion and the adjacent wall surface are connected by a fixing means. Connected type folding stage. (10) The connection according to claim 5, wherein the height of each divided stand of both stage units when extended in a series is individually changed so that there is a step on the entire stage surface with each divided stand as a unit. type of folding stage.
