  • the front end portion of the flap is gradually pressed and rises, as shown in FIG. 70(B) , and when the canvases are finally wound and stored, the front end portion stands, as shown in FIG. 70(C) , so as to push up the bottom hem 2 of the wound canvas and support it in a tense state.
  • the projected corner canvases G 1 and G 2 can be prevented from becoming loose when the canvas is wound and stored, and thus, the force for tensing the canvas can be maintained so as to provide a good appearance.
  • the upper portion side is the projected corner canvases G 1 and G 2 and the lower portion side is the rectangular canvases P 1 and P 2 (recessed corner canvases P 3 and P 4 are also possible) in the combination, in the case of the complex devices SQII 5 • 6 • 8 , where the above described canvases are upside-down, in terms of the layout, the bottom hem 6 of the rectangular canvases P 1 and P 2 on the upper portion side is pressed and pushed up by the fluctuation flap 62 , which is attached to the rear upper end portion of the front bar R 3 on the outer side.
  • the canvases G 1 , G 2 , P 1 and P 2 on the upper portion side and on the lower portion side are wound in sync so that the bottom hem 2 and 6 of the upper portion side canvas are pressed and pushed up by the fluctuation flap 62 , and thus, the upper portion side canvas can be wound and stored in such a state as to have appropriate tenseness.
  • 631 is an expandable net made of rubber for supporting the projected corner canvases G 1 and G 2 in a tense state, and provided on the rear surface of the projected corner canvases G 1 and G 2 close to the bottom hem 2 .
  • the elastic force resulting from the expandable net 631 is effectively applied when the projected corner canvas G 1 or G 2 in the complex devices SQII 1 to 4 and SQII 7 is spread to the front to the maximum, and thus, the projected corner canvas G 1 or G 2 is kept in a tense state.
  • an expandable net 631 which is the same as in the above is spanned on the rear surface of the rectangular canvas P 1 or P 2 on the upper portion side close to the bottom hem 6 , and thus, the canvas on the upper portion side is tensed when the canvas is spread, and in addition, the portion of the canvas on the upper portion side which becomes loose is absorbed so as to provide a good appearance when the canvas is wound and stored in the case of the complex devices SQII 5 • 6 • 8 , where the canvases G 1 , G 2 , P 1 and P 2 on the upper portion side and the lower portion side are combined upside-down, in the same manner as in the case of the embodiment using the above described fluctuation flap 62 .
  • the projected corner canvas G 1 or G 2 is wound from beneath and the rectangular canvas P 1 or P 2 is wound from above (recessed corner canvas P 3 or P 4 is also possible) or, in contrast, the rectangular canvas P 2 is wound from beneath and the projected corner canvas G 1 or G 2 is rolled from above, and thus, it is taken into consideration that the gap between the top portions 1 of the canvases after being spread and the step in the vicinity of the border between the projected corner canvas G 1 or G 2 and the rectangular canvas P 1 or P 2 becomes inconspicuous.
  • the distance between the axes of the winding roller J 1 to J 7 for the projected corner canvas G 1 or G 2 and the winding roller 30 or 30 a for the rectangular canvas P 1 or P 2 is constant, however, and it is difficult to prevent the gap between the top portions 1 of the canvases after being unwound and spread from becoming great as a result, in comparison with when the respective canvases G 1 , G 2 , P 1 and P 2 are wound and stored.
  • FIGS. 72(A) to 72(E) disclose a process through which the gap between the top portions 1 of the canvases after the two canvases G 1 and P 1 are spread is narrowed.
  • 97 is a fluctuation flap for the projected corner canvas G 1 and the rectangular canvas P 1 which are respectively incorporated in the casings K 1 and K 2 , and the axial portion 971 , which are formed in the base portions, are supportedly inserted into the bearing portion 136 formed in a portion on the inner wall directly above the opening through which the canvas is drawn out 131 in the upper portion side casing K 1 , and in addition, into the bearing portion 136 formed on the inner wall directly beneath the opening through which the canvas is drawn out 132 of the casing K 2 on the lower portion side.
  • 98 is a plate spring in a reverse V shape for respectively pressing and supporting the fluctuation flap 97 which is sandwiched between the rear surface of the front plate of the casings K 1 and K 2 and the fluctuation flap 97 .
  • a spring is provided so that the fluctuation flap 961 is pressed against the front surface of the canvas that has been wound around the winding roller J 1 to J 7 , and in addition, in the case of the fluctuation flap 97 for the rectangular canvas P 1 , a spring is provided so that the fluctuation flap 97 is pressed against the surface of the canvas that has been wound around the winding roller 30 or 30 a.
  • the fluctuation flap 97 is pressed down against the pressing force of the plate spring 98 , as shown in FIG. 72(D) , so that the height of the gap ⁇ shown in FIG. 72(E) is narrowed in the vicinity of the opening for pulling out the canvas 131 on the upper portion side and in the vicinity of the opening for pulling out the canvas 132 on the lower portion side when the canvas is finally pulled out and spread, and the fluctuation flap functions to create an appropriate tenseness on the two spread canvases G 1 and P 1 .
  • the fluctuation flap 97 is engaged with the protrusion 99
  • the front end portion of the fluctuation flap 97 can be formed in undulated form or uneven form, or protrusions can be formed so as to engage with engaging holes (not shown) created at a distance from each other in locations close to the top portions of the two canvases G 1 and P 1 .
  • the fluctuation flap 97 is pressed and supported in top-down symmetry in portions on the inner wall above and beneath the opening through which the canvas is drawn out 133 , and thus, the gap between the canvases is further narrowed.
  • the outer rollers 12 and 12 a are formed so as to be guided and freely slidable along the inner rollers 11 and 11 a , the two can have such a structure as to move relative to each other by means of bearings, and thus, the resistance against sliding when the outer rollers 12 and 12 a move forward and backward can be greatly reduced.
