Definitions

  • the invention relates to a water barrier, in particular to a water barrier which can be transferred from an inoperative position into a water-retaining condition and vice versa.
  • Water barriers comprising a watertight cloth are known, such as from DE 35 27 100, and from DE 20 56 356. From these documents water barriers are known wherein a cable is provided in a seam of the cloth, which cable, at intermediate distances, is attached to pole structures.
  • the frame has two posts and a sill extending therebetween.
  • the sill can be a bottom sill or a top sill.
  • the storage space can be situated in the sill. Alternatively the storage space can be situated in a post of the frame.
  • the transfer means comprise a drive mechanism, which comprises a driven element that drivingly 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.
  • a drive mechanism which comprises a driven element that drivingly 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.
  • the driving element may extend over at least substantially the entire passage, parallel to the direction of movement of the cloth.
  • 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.
  • the cloth can be entirely flat, which is advantageous for storage, particularly on a roll. Both longitudinal edges can be designed in that way.
  • the cloth may in essence have the appearance of a film for a projector or camera.
  • the driven element engages onto a lower longitudinal edge of the cloth.
  • the cloth is directly or indirectly guided in a (stationary) guide/in guides.
  • Said guide may have an access for the cloth, which access is situated aligned with the main plane of the cloth.

They may be deformable themselves, in order to then start clamping the cloth. In that case use can be made of wedging action as well. It is also possible to make use of clamping blocks that are shape-retaining and will provide the clamping force through wedging action with the guide.
  • the projections can be rotatably attached to the driven element, particularly be rolling freely over the wedge, particularly rotatable about centre lines that are transverse to the cloth.
  • a driven element in the form of a toothed cable.
  • Such an embodiment may be advantageous because as a result of its cross-section it can more easily be fittingly and slidably accommodated in a guide. In turn this is advantageous in preventing dirt from penetrating, particularly undesirable when the guide is situated in a bottom sill.
  • the teeth can then extend sidewards, so that the cable can be upwardly shielded.
  • the stiffening is guided with a lower end in a bottom sill, particularly a rail.
  • the guiding of the stiffening in the bottom sill can then be designed for keeping the stiffening upright during its movement.
  • At least two adjacently positioned water barriers have one common post.
  • Said common post may be provided with a storage space for the cloth of the one water barrier and with means for holding the leading edge of the cloth of the other adjacent water barrier.
  • the common post may be provided with a storage space for the cloth of the one water barrier and with a storage space for the cloth of the other adjacent water barrier.
  • the frame comprises a post or sill provided with an accommodation space for the leading edge with stiffening in the water-retaining condition.
  • the accommodation space can be provided with operable locking means for locking the stiffening in the accommodation space.
  • the post or sill in question can be provided with a water seal cooperating with the cloth.
  • the stiffening may be part of means for guiding the edge or edges transverse to the leading edge and along one or more sills, or one or more posts, respectively.
  • Creases in the cloth can be further counteracted when means are provided that press against the roller and that stretch the cloth in sideward direction in order to prevent creases during rolling up.
  • the storage space preferably is provided with a water-sealing cooperating with the cloth.
  • the cloth which is watertight, preferably is manufactured of ultra high-strength fibres, particularly of PE, which cloth is flexible, can be rolled up and shows little stretch.
  • An example is Dyneema (registered trademark).
  • the invention furthermore, according to a further aspect, provides a cloth for a water barrier, wherein the cloth can be rolled up and at one or both longitudinal edges is provided with a series of holes for cooperation with projections of a drive for the cloth.
  • the posts and/or sill with storage space can be permanent.
  • the invention provides a continuous assembly of several water barriers according to the invention.

  • the release of cloth 10 can among others be achieved by means of an electromagnetic unlocking 19 which on (remote) signal releases the roller 15 .
  • the roller 15 is rotatable to a limited degree around the inner bush 13 in order to compensate for a difference in diameter occurring between the rolled up cloth and rolling in the draw wire 6 b .
  • the winding bush 12 may be provided with an internal roller motor or tube motor that ensures rolling up or rolling down in an electrically driven manner.

  • the seam 10 a is shown in the operational position. In FIG. 4 the seam can also be seen as 10 a + 6 a . This specific condition is the solution for the storage of the volume of the seam with the draw wire in there.
  • the shape of the seam 10 a is able to adapt to different functions.
  • condition 10 a + 6 a can be achieved by rolling the seam 10 a along a roller 13 a wherein the seam 10 a with the loose wires 6 a in there, acquire a flattened condition (one-dimensionally grouped arrangement) so that more windings can be accommodated in space 16 .
  • FIG. 5 shows a number of loose stretching wires 6 a in cross-section that are bundled together in the seam 10 a by a pull in the transverse direction in order to form a body in that way that presses against the wedges 30 .
  • said wedges 30 will want to move in transverse direction within the profile 3 of the guide, and thus will perform a clamping function on the seam 10 a in the area of 30 b as a result of which the transverse forces that the cloth 10 may exert, are utilised to prevent shifting of the seam.
  • the clamping cooperation between cloth 10 , wedges 30 and guide profile 3 is such that it also results in watertightness.
  • the wedges 30 can be of relatively hard material and the profile 3 of the guide of relatively softer material, in order to thus achieve an improved watertightness.
  • This softer, resilient material also enables to achieve a damping action for cases/moments at which heavy forces are exerted on the water-retaining cloth due to heavy wave action or as a result of impacts due to collisions. High peak tensions are thus counteracted, as the tensions are better distributed over the cloth, as a result of which the loadability of the structure increases.
  • the said resilience also allows for tension of the cloth with the shortest distance to the guide with seam at the level of an impact being dispersed to a certain degree and the chance of the clamping of the seam being sufficient being increased.
  • FIG. 6 shows a cloth 10 according to the invention that can be clamped with wedges 30 .
  • Said clamping can be necessary when using a more rigid, sheet-shaped material, that cannot be folded flat but can indeed be slightly bent around and then being unable to follow the deformation like in FIG. 4 / 5 , other than being rolled up.
  • a relief either in or on the coating on the side edges of sheet 10
  • grip can be exerted on the sheet 10 by means of a counter relief 30 a at the inside of the wedges 30 as a result of which forces that are oriented transverse can be taken.
  • the cloth 10 is furthermore provided with a series of holes 110 at the longitudinal edge(s).
  • said series of holes 110 is intended for engagement by projections on a drive.
  • the drive in this case runs parallel to the longitudinal edge, and therefore engages the longitudinal edge over a considerable length.
  • the drive is in this case a toothed belt 16 , which is provided with teeth 16 a , 16 b on both sides.
  • the teeth 16 a fittingly mesh with the holes 110 .
  • the teeth 16 b serve as engagement means for the actual drive, a wheel 13 driven by motor 40 and rotatable on foot 14 in the bottom sill 20 and provided with holes for fitting, driving accommodation of the teeth 16 b .
  • the cloth itself can be rolled up on roller 12 rotatable about axis 12 a.
  • the cloth 10 extends between wedge blocks 30 a,b that are placed in a section 3 accommodating wedge blocks 30 a,b , as a result of which a guide for the cloth 10 is formed near the cloth edge.
  • the section 3 is relatively shape-retaining or rigid, also see the horizontal cross-section of FIG. 8A .
  • the wedge blocks 30 a,b for instance of vulcanised TP, are provided with vertical, parting slits 31 , that have a straight portion 31 a and a round end portion 31 b .

  • a force F see FIG. 8B will be exerted on the cloth, as a result of which the longitudinal edge on the drawing will tend to the right.
  • the belt 16 with side 16 c then also starts to press against plane 30 d of wedge block 30 b and starts movement/deformation (I) of wedge block 30 b .
  • Both blocks 30 a,b are subjected to counterforce from guide 3 , indicated by small force arrows. Due to the slits 31 the wedge blocks 30 a,b are able to deform, see arrows M 1 and M 2 , as a result of which their surfaces facing the cloth 10 are clamped against the cloth, resulting in the cloth being stopped from further movement out of the passage 3 a .
  • the cloth 10 is thus secured to said edge.
  • the same structure can be present in case of posts. The clamping cooperation between cloth, wedge blocks and profile enhances the watertightness along the cloth edge.
  • the clamping force needs to be very high, use can be made of the presence of the slits 31 , by placing a steel clamping strip 3 therein, which has a thickened origin 32 b fitting in the round portion 31 b and a strip member 32 a . Due to the deformation of the wedge blocks 41 a,b the clamping strips 32 rotate along, directions N 1 and N 2 wherein their acute edges 32 c facing each other forcefully engage in the cloth, co-operatively. Due to the inclined position of the strips 32 a kind of locking against movement to the right of the cloth 10 is achieved.
