A floorboard 3 having a corresponding depth is provided, and a front floorboard 3 is provided with a front floorboard 3a continuous in the same plane as the floorboard 3 at the front end of the floorboard 3 in a state of being horizontally extended with the rear railing 8. It is configured to be able to be housed in the hangar H in a state in which the front haul 7a and the rear haul 8 are bent in two and the front floorboard 3a and the floorboard 3 are folded back up and deformed. The same reference numerals are given to the same or corresponding portions in the drawings, and description thereof will be omitted.

  Further, a floor plate 3 having a depth corresponding to the length thereof is provided on the rear pulling board 8, and the front pulling board 7 is provided on the front end of the floor board 3 in a horizontally extended state from the base end to the rear pulling board 8. A front floor plate 3a having a continuous depth is provided on the same plane as 3.

  The front end of the floor plate 3 serving as the upper end in a state in which the front slab 7 and the rear slab 8 are bent in two at their connecting portions 13 and the floor plate 3 and the front floor plate 3a are folded back and folded back to back. The ceiling height of the hangar H is set corresponding to the above, and the floor plate 3 is positioned on the same vertical plane as the wall surface W at the upper end of the opening H1 of the hangar H to close the opening H1 (Fig. 14).

  The floorboard 3 is set to have a depth larger than that of the front floorboard 3a (hereinafter, also simply referred to as floorboard 3a), but both floorboards 3 and 3a are set to have the same horizontal width (two points are shown in FIG. 12 for convenience of explanation). It is indicated by a chain line.) Between the floor plates 3 and 3a and the front and rear rails 7 and 8, at predetermined intervals in the front-rear direction so as to be orthogonal to the front and rear rails 7 and 8. A plurality of joists 14 and 14a arranged in parallel (in FIG. 2, only a part is shown by a chain double-dashed line for convenience of description, and others are omitted) are fixedly interposed.

  The total length of the joists 14 below the floor plate 3 is set to be the same as the distance between the front bundle columns 4 on the left and right sides, and the total length of the joists 14a below the front floor plate 3a is equal to the distance between the rear bundle columns 5 on the left and right sides. It is set to the same length.

  In the wall storage stage 1 and 1a configured as described above, the front Daihiki 7 and the rear Daihiki 8 are bent in two at the connecting portion 13 thereof and bent as shown in FIGS. When the floor plate 3 is erected on the upper side of the floor plate 2, the roller 23a biased upward by the spring 29 of the roller plunger 23 at the upper end of the floor plate 3 is placed in the recess 35 of the roller receiver 24 provided at the upper edge of the opening H1 of the storage H. Since the roller 23a is locked and constantly presses the concave portion 35 upward by the urging force of the spring 29, the upper end of the floor plate 3 in the upright state is integrally connected to and supported by the wall W in which the hangar H is provided. State is maintained stably.

  Then, the stages 1 and 1a are housed in the hangar H so that the floor plate 3 is located on the same vertical plane as the wall surface W at the upper end of the opening H1 of the hangar H and closes the opening H1.

  In order to transform the stage 1 or 1a stored in the wall into a stage, the curtain plate 2 together with the floor plate 3 is pulled out from the hangar H to the rear of the outside thereof, the drafts 7 and 8 are tilted, and the roller 23a is recessed in the roller receiver 24. Remove from 35.

  The front and rear large pulls 7 and 8 and the spring support rod 17 have the same elevation (swing) direction, but the respective rotation centers are different, and the tip end side of the spring support rod 17 is attached to each of the large pulls 7 and 8. Since it can be advanced and retracted by inserting the fixed spring retainer 18, it follows the elevation of the hauls 7 and 8.

  For this reason, when the upright tugs 7 and 8 shown in FIGS. 7 and 14 are tilted, the penetrating protrusion length of the spring support rod 17 on the tip side with respect to the spring retainer 18 gradually increases, and therefore the spring retainer 18 and the spring retainer 18 Since the space between 16 is narrowed and the floor plates 7 and 8 are in an upright state and in an unloaded state, the compression coil spring 15 having a free height is gradually compressed to apply a load, and the floor plates 3 and 3a together with the large pulls 7 and 8 are provided. The stage is arranged horizontally.

  Also, during the tilting of the large pulls 7 and 8, the same load acts on all of the compression coil springs 15a, 15b and 15c, and when the load is small, the compression coil springs 15a, 15b and 15c have three spring constants. Is small and the ratio of shrinkage is larger than when only one is used, so that the floor plates 3 and 3a can be tilted flexibly together with the large pulls 7 and 8 even if the same load is applied.

  Then, when the gradient of the floor plates 3 and 3a becomes gentle and the load becomes extremely large and the compression coil springs 15a, 15b and 15c do not contract in order from the smallest spring constant, the overall spring constant is the same as the largest spring constant. Becomes larger and the rate of shrinkage becomes smaller.

  In this way, the spring constant can be changed according to the magnitude of the load, and it can be tilted relatively smoothly at the beginning of tilting, and when the gradient approaches horizontal, it gradually resists the biasing force of the compression coil spring 15. Since the floor plates 3 and 3a are rapidly compressed, the swing is gentle without causing a shock to the floor surface f, and the floor plates 3 and 3a can be tilted favorably and safely transformed into the stage. To be

  In the stage 1a, since the roller 23a projects from the front end of the floor plate 3 while the floor plates 3 and 3a are tilted, the roller 23a contacts the rear end of the opposing floor plate 3a. Since the floorboards 3 and 3a move backward and escape, the floorboards 3 and 3a move smoothly and move upright or horizontal without any trouble.

  Further, when the floor plates 3 and 3a in the horizontal state are deformed upright, the compression coil springs 15 in the compressed state are urged in the standing direction of the floor plates 3 and 3a, and the urging force of the compression coil springs 15 raises the heavy floor plates 3 and 3a. The force that tries to lift in the direction is assisted, and the stage can be smoothly deformed upright with a light force.

  At this time, since the compressed compression coil springs 15a, 15b, 15c extend in the reverse order of the above, at the beginning of standing, the floor plate 3, with a large urging force of only the one having the largest spring constant and a small extension, is used. When the inclination of 3a can be assisted and the inclination thereof increases, the compression coil springs 15a, 15b and 15c extend, so that the floor plates 3 and 3a can be made to stand up relatively smoothly, and the roller 23a of the roller plunger 23 is recessed in the roller receiver 24. It rolls while being pressed downward against the biasing force of the spring 29 on the front inclined surface of the roller, and is arranged in the center of the recess 35 of the roller receiver 24.
