PROBLEM TO BE SOLVED: To provide a foldable storage type stage that is enabled to satisfactorily perform deformation operation of a stage even more by controlling a compression spring.SOLUTION: A foldable storage type stage is characterized by: externally fitting a compression spring 17 of an unloaded state while folding stage boards 4, 5 at a lower part from a base end pivot of the stage boards 4, 5 in short pillars 2, 3; also, swingably pivoting a base end of a spring support rod 19 with a spring holder 18 for stopping and supporting one end of the compression spring 17 provided at the base end side in the elevation direction of the stage boards 4, 5; fixing a spring presser 20 coming into abutment with the other end of the compression spring 17 of the unloaded state and loosely fitting a tip side of the spring support rod 19 in the proper position of the stage boards 4, 5; installing an automatic or hand-operated feed screw mechanism part 26 to one stage board 5; providing a moving body 35 capable of reciprocating in the longitudinal direction of the stage board 5 by the rotation of a feed screw rod 33 in the feed screw mechanism part 26; and pivoting and coupling a link 39 undulating according to the movement of the moving body 35 between the moving body 35 and the proper position of the short pillar 3 pivoting the stage board 5.SELECTED DRAWING: Figure 1
【課題】圧縮コイルバネを制御することにより、より一層舞台の変形操作を良好に行える様にした折り立て収納式舞台を提供する。【解決手段】束柱２、３において舞台板４、５の基端枢軸より下方には、舞台板４、５の折り立て状態で無負荷状態の圧縮コイルバネ17を外嵌すると共に、該圧縮コイルバネ17の一端を当止め支持するバネ受け18を基端側に設けたバネ支持杆19の基端を舞台板４、５の俯仰方向に揺動自在に枢着し、無負荷状態の前記圧縮コイルバネ17の他端に当接してバネ支持杆19の先端側を遊嵌するバネ押え20を舞台板４、５の適所に固定し、一方の該舞台板５には、自動又は手動操作される送りねじ機構部26を設置し、該送りねじ機構部26には、送りねじ棒33の回転により舞台板５の前後方向に往復可能な移動体35を設け、該移動体35と舞台板５を枢着した束柱３の適所との間に移動体35の移動に応じて起伏するリンク39を枢着連結する。【選択図】図１
