Water barrier

Abstract

Water barrier including a frame having tow posts and at least one sill extending therebetween, which posts and sill bound a passage that can be closed off against water, further including a flexible water-retaining cloth, a storage space for the cloth and a transfer element for transferring the cloth from a storage condition accommodated in the storage space, wherein the passage is open, to a water-retaining condition, wherein the passage is at least partially closed off by the cloth.

         75 . Water barrier comprising a frame bounding a passage that can be closed off against water, further comprising a flexible water-retaining cloth, a storage space for the cloth and transfer means for transferring the cloth from a storage condition accommodated in the storage space, wherein the passage is open, to a water-retaining condition, wherein the passage is at least partially closed off by the cloth. 
     
     
         76 . Water barrier according to  claim 75 , wherein the frame has two posts and a sill extending therebetween. 
     
     
         77 . Water barrier according to  claim 76 , wherein the frame comprises a bottom sill and/or top sill. 
     
     
         78 . Water barrier according to  claim 75 , comprising means for rolling up the cloth or folding it together in the storage space. 
     
     
         79 . Water barrier according to  claim 75 , wherein the storage space is situated in the sill. 
     
     
         80 . Water barrier according to  claim 75 , wherein the storage space is situated in a post of the frame. 
     
     
         81 . Water barrier according to  claim 75 , wherein the transfer means comprise a drive mechanism, which comprises a driven element that engages onto a longitudinal edge of the cloth, which longitudinal edge extends in direction of movement of the cloth between the storage condition and the water-retaining condition edge of the cloth. 
     
     
         82 . Water barrier according to  claim 81 , wherein the driven element is endless and circulating and at evenly distributed locations drivingly engages onto the longitudinal edge of the cloth. 
     
     
         83 . Water barrier according to  claim 82 , wherein the driving element extends over at least substantially the entire passage, parallel to the direction of movement of the cloth. 
     
     
         84 . Water barrier according to  claim 82 , wherein the driven element only engages onto the part of the cloth that is discharged from the storage space. 
     
     
         85 . Water barrier according to  claim 81 , wherein the cloth is provided with a series of holes in the longitudinal edge and the driven element is provided with projections for driving engagement in the holes. 
     
     
         86 . Water barrier according to  claims 81 , wherein the storage space is situated in a post of the frame and wherein the driven element engages onto a lower longitudinal edge of the cloth. 
     
     
         87 . Water barrier according to  claim 81 , wherein the storage space is situated in the sill and wherein the driven element engages onto a vertical longitudinal edge of the cloth. 
     
     
         88 . Water barrier according to  claim 87 , wherein a driven element engages onto each vertical longitudinal edge of the cloth. 
     
     
         89 . Water barrier according to  claim 75 , wherein the cloth is provided with a thickening at at least two edges that are situated opposite each other. 
     
     
         90 . Water barrier according to  claim 89 , wherein the thickening is at least also formed by cloth edge material folded back onto itself, which preferably is attached onto itself. 
     
     
         91 . Water barrier according to  claim 89 , wherein the thickening is deformable in transverse direction. 
     
     
         92 . Water barrier according to  claim 89 , wherein in a post or sill the frame is provided with a guide for the thickening. 
     
     
         93 . Water barrier according to  claim 82 , wherein the thickening in the water-retaining condition of the cloth engages onto the guide in a watertight manner. 
     
     
         94 . Water barrier according to  claim 89 , wherein the thickening comprises a flexible cord, preferably accommodated in the cloth edge material, optionally over a limited portion of the edge in question, wherein the flexible cord preferably is formed by a group of parallel elements, such as threads, which in a direction transverse thereto can be moved with respect to each other for assuming different shapes, particularly between a two-dimensionally grouped arrangement, such as in an ellipse or circle, and a one-dimensionally grouped arrangement, such as a linear arrangement of a series of adjacently situated elements.
