Definitions
- Shutter-type roll-up device for concealing an opening comprising watertight means
- the present invention relates to the field of building, public or private, particular, community or industrial, and relates more particularly to the field of closing, occultation and especially securing vis-à-vis the flooding of doors, windows or bays of a residential building such as private or collective housing, or of an industrial building such as a business, factory, garage/parking lot or warehouse.
- the first function is of course to close the opening, in particular to prevent anyone from entering the building (residential or industrial/commercial premises) and/or to place a room (bedroom for example) in the dark or in the dark .
- Another known function is to provide thermal and/or sound insulation to the building.
- the present invention aims to remedy these drawbacks with a totally innovative approach.

- FIGS 1 to 62 show different modes of design and operation of a roll-up device 1 of the roller shutter or sectional door type.
- This roller shutter 1 is intended to be installed in any type of industrial building (warehouse, factory, etc.), commercial (shop, restaurant, offices, etc.), private (housing, garage, etc.), collective (building of , cinema, shopping center, etc.) or public (administration, school, etc.), in order to close / protect an opening 2 made in a wall 3, such as a wall erected on the ground 4, equipped or not a window, a bay (fixed or sliding), a door, a French window or any other equivalent equipment.
- the opening 2 provided in the wall 3 and where the roller shutter 1 is installed will define a substantially vertical general blocking plane P.
- the roll-up device 1 of the present invention is designed in such a way, in particular but not only, to protect the interior of buildings from floods, storms and of certain break-ins.
- the roll-up concealment device 1 typically comprises a closing apron 10 comprising a series of hollow-core transverse slats 11 which are hinged longitudinally together thanks to the cooperation of their profiles. respective, and a rigid outer frame 20. These slats 11 are hinged together at their respective upper and lower 11a longitudinal edges 11b, and they extend transversely in the frame 20, which is firmly fixed in the opening 2 formed in the wall 4.
- the shutter apron 10 comprises specific upper 12 and lower 13 slats respectively, between which are articulated a multitude of intermediate slats 11, preferably alternately identical according to their parity (even/odd).
- the shutter apron 10 also has a front face lOf facing the outside of the wall 4 and a back face lOd facing the inside of the building.
- the frame 20 typically comprises meanwhile:
- a lower chute 23 also with a "U" profile with a bottom wall 23b preferably resting on the ground 4 and two wings parallel to each other, namely a front wall 23f and a back wall 23d, according to the outside/inside direction implantation of the device 1 in the building to be protected.
- Second of all the side guides 22 must be waterproof. It is therefore preferable to embed them in the wall 3, by fixing them for example using a thermosetting type resin. It is also advisable to embed the lower chute 23 on the ground 4 to retain the bending of the shutter apron 10.
- the first condition for guaranteeing sealing is therefore the stiffness of the sealing apron 10. Indeed, under the pressure of the water (arrows F), this sealing apron 10 will deform. More precisely, the lowest slats 11 (those subjected directly to the pressure of the water but also a few slats above the water level) will hollow out in a more or less rounded manner in the center to form a curved belly both vertical and transverse/horizontal, the slats subjected to the greatest frontal stress (water pressure) digging furthest towards the interior of the building. If the apron deforms too much, the slats 11 risk moving apart, or even coming out of the side guides 22 and the device 1 is ineffective or even destroyed.
- the choice of material constituting the hollow slats 11, 12 and 13 was therefore made of aluminium, to have a good price/stiffness/strength ratio and for the ease of extrusion of the profiles to be manufactured.
- the slats 11, 12 and 13 must be able to pivot relative to each other to guarantee good flexibility and therefore easy winding around the motor shaft 30. All the subtlety lies in the profile of the grip between the slats 11 at the level of the upper longitudinal edge IIa of a slat 11 considered and the lower edge 11b of an upper slat.
- curved profiles in the form of hooks of known type are provided to vertically link the slats to each other while allowing their longitudinal pivoting (substantially horizontally therefore) as explained above so that they are positioned correctly in the side slides 22 .
- the primary idea is first of all to position the slats 11 in an “accordion” fashion when the shutter 10 is closed, by a support angle system.
- This support, or seat is made naturally by the angle existing between each slat and makes it possible to guarantee the different types of sealing which will be described later.
- the slats 11 of the shutter apron 10 are provided to slide freely vertically from top to bottom and vice versa between the side walls 22f and 22d and the bottom wall 22a of the side slides 22, which therefore act as a kind of rails guidance.
- the section of the "U" of the side slides 22, that is to say the distance D between the front 22f and back 22d walls, is greater than the thickness E of the slats 11.
- the shutter apron 10 can take three main positions, namely a first inactive raised position ( Figure 2) in which the slats 11 are rolled up on each other around the motor axis 30 (connected to a drive device not shown), a second active lowered position (FIG. 3) in which said slats 11 are unrolled and constitute the closure apron 10 of said opening 2, which already provides a first watertightness (or other) thanks in particular to the interslat sealing means which will be described later, and a third position of reinforced sealing (FIG.
- a force F for example the pressure exerted by a height/column of water during a flood, the force of the wind during a (violent) storm or the weight of an individual who wishes to force the shutter apron 10 (byexample shoulder, kick or battering ram).
- the slats 11 are arranged vertically "in accordion” in the lateral slides 22 and form between them a frontal angle a between two consecutive slats respectively "pair and “odd” (or vice versa) and a dorsal angle 3 between two consecutive “odd” and “even” slats, these two angles being different from 180°.
- angles a and 3 are opposite (one is positive and the other is negative) and possibly identical in absolute value so that the shutter apron 10 forms a regular "accordion" with alternating inclination slats 11 (one inclined in one direction, one in the other, and so on, according to their parity).
- the angles a and 3 are for example comprised, in absolute value, between around 90° and 179°, preferably between around 125° and 175°, and advantageously between 150 and 170°.
- the slats 11 take, as indicated above, a third position lowered protection and sealing to the fluid when the closure apron 10 is subjected to a frontal force F as described above.
- this position two consecutive slats 11 form between them an angle a or 3 which will approach 180° (the slats pivot between them) in absolute value, or even equal to 180°, so that the shutter apron 10 is almost flat and arranged in the general shutter plane P.
- This concept of flat shutter apron which is a fiction, will be explained below. What must be remembered is that in the third position certain slats will pivot between them two by two and alternately in one direction and in the other over a certain height corresponding overall to the height of the water exerting its frontal thrust on the shutter apron 10.
- the angles a and 3 can thus for example pass respectively from +150° and -150° to +180° and -180 ° “plane” apron, or even slightly beyond, for example +190° and -190°.
- the thrust of the water will deform the sealing apron 10 to give it the shape of a "belly" hollowed out towards the inside of the building. It is therefore not really flat but the slats 11 which will pivot will almost be so if one places oneself at the level of the wings 22.
- the closure apron 10 is provided with a first longitudinal means 40 of interslat passive sealing supporting a low pressure used in particular when the frontal pressure F exerted on the slats 11 is low or even almost zero.
- the first longitudinal passive low-pressure sealing means 40 comprises, on the lower longitudinal edge 11b of a first slat 11 considered, a prominent transverse rib 41 and, on an upper longitudinal edge 11a of a slat 11 lower than said first slat 11 in question, a transverse groove 42 enclosing a first flexible transverse joint 43.
- These elements 41 to 43 are placed closer to the front surface 10f of the closure apron 10 than to its back surface 10b.
- the prominent transverse rib 41 compresses the first flexible transverse joint more and more strongly. 43 in its groove 42 as said slats 11 pivot in order to make the device 1 fluid tight by forming a low pressure seal.
- the closure apron 10 is provided with a second longitudinal means 50 of interslat passive sealing supporting a high pressure used in particular when the frontal pressure F exerted on the slats 11 is important, even very important (flooding at high height of the water level, strong storm, pressure of an individual using his force or using a ram).
- the second longitudinal passive high-pressure sealing means 50 comprises, on a dorsal face lld of the front part lOf of a first slat 11 considered of the closure apron 10, a transverse housing 51 receiving a second flexible transverse joint 52 cooperating with a front face 53f of a hinge hook 53 of a slat 11 lower than said first slat 11 considered. These elements are also placed closer to the front surface 10f of the closure apron 10 than to its back surface 10d.
- the first longitudinal passive low-pressure sealing means 40 comprises, on the upper longitudinal edge IIa of a first slat 11 considered, a prominent transverse rib 44 and, on a lower longitudinal edge 11b of a slat 11 higher than said first slat in question, a transverse groove 45 containing a first flexible transverse joint 43.
- These elements 41 to 43 are placed closer to the front surface lOf of the closing apron 10 than to its dorsal surface 10b.
- the prominent rib 44 compresses the first flexible joint 43 more and more strongly in its groove 45 as said slats 11 pivot in order to render the device 1 fluid-tight by forming a low-pressure seal. Note that all the first transverse seals arranged between two consecutive slats will not necessarily be crushed progressively as the slats pass from the second position to the third lowered sealing position.
- the second longitudinal passive high pressure sealing means 50 comprises, on a front face 53f of the hinge hook 53 of a first slat 11 considered, a transverse housing 55 containing a second flexible transverse joint 52 cooperating with the dorsal face lld of the front part lOf of a second slat 11 lower than the first slat 11 considered. These elements are placed closer to the front surface lOf of the shutter apron 10 than to its back surface 10b.
- first flexible transverse seal 43 and the second flexible transverse seal 52 are made of silicone (of the staminalene type) or of EPDM, of preferably fire resistant, and both come in the form of a band with a polygonal, circular or preferably oval section.
- the joints may also be hollow to reduce the weight of the deck and improve their crushing and therefore the high and low pressure seals.
- the device 1 comprises, at the level of the lower slat 13, a third longitudinal means 60 of low pressure passive lower sealing and a mobile cowling 70.
- this third longitudinal means 60 of low pressure passive lower sealing comprises a third flexible transverse seal 62, for example made of silicone of the staminalene type for its resistance to cycled mechanical loads and to temperature, housed in a transverse groove 63 of the lower longitudinal edge 13b of the lower end slat 13.
- a third flexible transverse seal 62 for example made of silicone of the staminalene type for its resistance to cycled mechanical loads and to temperature, housed in a transverse groove 63 of the lower longitudinal edge 13b of the lower end slat 13.
- the movable dust cover 70 serves for its part to prevent the intrusion of foreign bodies inside the lower chute 23 when the flap 1 is raised, to more easily guide the lower slat 13 in its housing and to prevent the unhooking of the lower slat 13 (untimely raising of the deck) in the event of rising water.
- This cowling 70 comprises an upper closing cover 71 articulated on an upper wall 23a of the lower chute 23, a leaf spring 72 bearing on the one hand against a lower groove 73 of the upper closing cover 71 and on the other hand inside the lower chute 23, for example at the junction angle of its dorsal 23d and bottom 23b walls, a hook 75 provided on the front face lOf of the lower slat 23, and a hook internal 76 secured to the front wall 23f of the lower chute 23.
- the third flexible transverse seal 62 bears against the closure cap 71 to provide passive low-pressure sealing.
- a force F is applied to the front face lOf of the shutter apron 10
- the slats 11 pivot longitudinally relative to each other along their respective upper and lower edges 11b, which causes the movement of the slat lower 13 towards the lower chute 23.
- This movement is accompanied by a vertical downward thrust of the lower slat 13 on the closing cap 71 via the third flexible transverse seal 62, which has the effect of pivoting said cover 71 against the elastic return force of leaf spring 72, as shown in Figure 9.
- the third transverse flexible joint 62 presses against the bottom wall 23b of the lower chute 23, thereby creating a fluid seal (FIG. 9).
- the third flexible transverse seal 62 is housed in a transverse groove 63 formed directly in the bottom wall 23b of the lower chute 23 in the form of a protuberance.
- This flexible transverse seal 62 protrudes upwards from the groove 63 so that, in the third lowered sealing position of the closure apron 10, said third transverse seal 62 is compressed between the lower longitudinal edge 13b of the lower slat 13 and said bottom wall 23b of lower chute 23 in order to seal device 1 from said fluid.
- Figure 12 illustrates a variant embodiment in which the hook 75 of the lower slat 13 is discontinuous, that is to say made up of a multitude of small independent hooks 75 and spaced longitudinally from each other. It may be interesting, in this configuration a priori lightened in weight, to reinforce the hooks 75 close to the center of the closing apron 10 because it is at this place that the frontal pressure force F risks being the highest on the shutter apron
- the elasticity of the leaf spring 72 makes it possible, once the hook 75 of the lower slat 13 is disengaged from the hook 76 of the lower chute 23, to raise said lower slat 23 and pivot the closing cap 71 in the direction reverses so as to return the mobile cowling 70 to its position for closing the lower chute 23 (FIG. 8).
- the device 1 is also provided with a fifth lateral sealing means 90 housed in each of the two lateral slides 22.
- This fifth lateral sealing means 90 mainly makes it possible to prevent water from infiltrating on either side of the sealing apron 10, and therefore into the protected building, in a zone which is particularly sensitive in terms of tightness.
- the system used for this purpose was designed on the one hand to ensure this seal in the event of low water pressure, but also in the event of high to very high water pressure (several tens of centimeters of water, or even more of one meter of water, pressing on the front face lOf of the shutter apron 10), in a simple, preferably automated way and without the supply of any additional energy source so that it can operate independently outside the presence of building occupants.
- the proposed solution also makes it possible to incidentally avoid lateral air infiltration in the event of strong gusts of wind.
- the fifth lateral sealing means 90 comprises a plug seal 91 in injected silicone provided with protrusions 91e which are inserted into the housings binds the two lateral ends 11c of each of the slats 11. These joints 91 made of injected silicone are fitted during the installation of the device 1 and remain integral with the slats 11 (for example by gluing, fitting, or other sealed mechanical connection).
- each plug seal 91 is also adapted to the particular rounded shapes of the curved parts of the respective upper and lower 11a edges 11b of said slats 11 in order to improve the seal over the entire height of the slat 11 considered. .
- the fifth lateral sealing means 90 also comprises a vertical joint 92 in the shape of a "U" (when viewed from above), for example made of injected silicone, against which a “floating” vertical plating rule 93, typically made of aluminium, can bear.
- the U-shaped vertical joint 92 and the rule vertical plating 93 are laterally movable in horizontal translation inside the side slides 22 from a few millimeters to a few centimeters so as to be able to approach the lateral ends 11c of the slats 11 (to create the lateral sealing) or on the contrary away from it.
- the vertical joint 92 in the shape of a "U” and the vertical plating rule 93 can be pressed together against the stopper joint 91 and against the front 22f and back 22d walls of each slide 22 using a member pressing 100, many design variants of which will be explained below and which do not require electricity (for almost all of the embodiments).
- the pressing member 100 of the fifth lateral sealing means 90 comprises a lateral activation rule 101 which can slide vertically in the space between the lateral ends 11c of the slats 11 and the bottom wall 22a of the lateral slides 22.
- the lateral activation rule 101 typically extends substantially over all or part of the height of the device 1, preferably at least two-thirds or even three-quarters of the height of the shutter apron 10 starting from the floor car this is the most flood prone area, and has a series of spaced windows 102 aligned vertically.
- This lateral activation ruler 101 is movable only vertically from top to bottom and from bottom to top to cause the horizontal linear displacement in the direction of the plug seal 91 of the assembly consisting of the vertical plating ruler 93 and the vertical seal in the form of of "U" 92. For this purpose, as illustrated in FIGS.
- the pressing member 100 comprises a pivoting bistable lever 103 provided with two arms 104 and 105 interconnected at the level of a horizontal axis of articulation 106 extending globally between the vertical wings 22f and 22d of each lateral slide 22.
- Each window 102 of a lateral activation rule 101 corresponds to a bistable lever 103 of this type, each lever 103 thus being placed substantially opposite an end 11c d a slat 11 considered / a plug seal 91.
- Each arm 104 of a lever 103 also carries a pressure shoe 107 (which can simply be constituted by the end of the arm 104) located opposite the vertical tack rule 93, also opposite a lateral end 11c d a slat 11/a plug seal 91.
- each lower arm 105 of a lever 103 is connected at its free end 105a to a tension spring 108 which allows bistable operation of the pressing member 100, said spring being moreover attached to a fixed upper pin 108a to put it in tension.
- the downward vertical linear displacement of the two lateral activation rules 101 causes the simultaneous pivoting of all the bistable levers 103, which come to press together on each of the two vertical rules of plating 93 located on either side of the slats 11 inside the side guides 22, then causing the compression of the side seals 92 in the shape of a "U” against the plug seals 91 of all the slats 11 and against the front walls 22f and dorsal 22d of each side slide 22.
- a watertight seal can already be produced if the side seal 92 bears against only one of the front 22f or dorsal 22d walls of each side slide 22 (preferably the front wall 22f because it is from this area that the water arrives).
- Tension spring 108 makes it possible, once a tipping point has been reached (FIG. 29) of the bistable system, to maintain sufficient pressure force so that vertical U-shaped seal 92 permanently compresses plug seal 91 and rests on the front 22f and back 22d walls of each side slide 22 in order to maintain lateral sealing in the event of a storm or an unexpected rise in water against the shutter apron 10.
- each lateral activation rule 101 is raised vertically, causing the bistable levers 103 to pivot in the opposite direction of rotation until reaching the reverse tipping point around the pivot axis 106 where the tension spring 108 pulls on the lower arm 105 of the bistable lever 103 to separate the pressure shoe 107 from the vertical plating ruler 93 (return to Figures 18 and 20 ).
- the U-shaped vertical seal 92 then ceases to be compressed by the vertical plating rule 93 against the stopper seal 91 of each slat 11 (return to Figure 17) and the front 22f and back 22d walls of each slide lateral 22.
- the vertical translation movement of the lateral activation rule 101 is controlled by a cable 110 connected directly to the winding shaft 30 of the shutter apron 10, as shown in Figures 20 to 29.
- the cable 110 is connected to a tension roller 111 and carries a pin 112 (or ballast) crimped on said cable close to said roller 111.
- An articulated lever 103a for example in the form of a finger with two branches , is connected on the one hand in an opening 103b of the upper end of the lateral activation rule 101 and on the other hand to a fixed pivot 106a around which it can turn thanks to said pin 112.
- the cable 110 drives the pin 112 downwards according to the direction arrow shown, which pin 112 then drives the lever 103a to pivot on its axis 106a to cause the side activation ruler 101 to descend vertically little by little, as illustrated by FIG. that the vertical seal 92 in the form of a "U” gradually approaches the stopper seal 91 in order to create the desired lateral sealing.
- the cable 110 continues to rotate in the same direction, as illustrated by FIGS. 24 then 25, so that the pin 112 passes the lever 103a (FIG. 24) then passes under the latter (FIG. 25).
- the return spring 108 produces the force necessary to permanently press the pressure shoe 107 against the vertical pressing rule 93, which then maintains the compression of the vertical joint 92 in the shape of a "U” against the plug joint 91 and against the front 22f and back 22d walls of each side slide 22.
- the lateral sealing of the closure apron 10 is therefore ensured and maintained.
- figures 26 to 29 illustrate the rotation in the opposite direction of the cable 110 and the raising of the pin 112 associated with this movement.
- the pin 112 then comes into contact with the underside of the rectilinear lever 103a (figure 26), raises said lever 103a to make it pivot in the opposite direction around the axis 106a (figures 26 then 27) so as to cause the side rule to slide activation 101 upwards, which has the effect of raising the arm 105 of the bistable lever 103 up to the tipping point and then beyond, this in order to separate the pressure pad 107 from the vertical plating rule 93 using the return spring 108.
- the vertical U-shaped seal 92 is then moved away from the plug seal 91 and the lateral seal ceases to act.
- the cable 110 continues to turn in order to place the activation rule 101 in the highest position (figures 28 then 29).
- FIGs 30 to 32 illustrate a lock 80 which makes it possible to block the shutter apron 10 in the low position directly using the activation rule 101.
- this lock 80 comprises a main body 81 mounted in rotation around 'a fixed axis 82 and provided with two parallel fingers 83 and 84 able to come into engagement with a transverse latch 85 linked to the activation rule 101.
- FIGS 33 and 34 illustrate an alternative solution with cables for vertically moving the lateral activation rule 101.
- a second independent motorization 35 is provided in the upper compartment 21.
- This second motorization 35 comprises a stepper motor 36 and a cable 110' mounted on upper 111a and lower 111b tension rollers and provided with a connection 36 to the upper roller 111b and a connection 37 to the lateral activation rule 101.
- the stepper motor 35 therefore rotates the upper roller 111b which thus drives the cable 110', which in turn causes the vertical displacement of the lateral activation rule 101 between the retracted position of the vertical tackle rule 93 and the advanced position of the latter p allowing the "U" shaped side seal 92 to be compressed against the plug seal 91.
- Counter rotation of the stepping motor 35 causes the "U" shaped side seal 92 to recoil from the plug seal 91.
- FIG 35 very schematically illustrates a solution in which the pressing member 100 is constituted by a series of lateral cams 131 vertically superimposed in the side slides 22 on either side of the slats 11.
- These cams 131 are integral with a common vertical shaft 132 pivoting in one direction or the other (or only in one direction depending on the configuration) so to act on the vertical plating ruler 93 to move the vertical seal 92 in the form of a "U" closer to or further from the stopper seal 91 in order to ensure or not ensure the lateral sealing of the device.
- means are provided to maintain the cams 131 in each of the positions, for example preloaded springs.
- Figures 36 and 37 show a solution in which the pressing member 100 comprises a series of pairs of compression springs 141 and 142 superimposed vertically in the side slides 22 on either side of the slats 11. These springs 141 and 142 are in a position of unstable equilibrium (a slight movement makes them pass from one state to another).
- An upper spring 141 is for example integral with a first fixed point 143 and a transversely mobile point 144, while a lower spring 142 is integral with a second fixed point 143 and said mobile point 144.
- FIGs 38 and 39 very schematically illustrate a solution in which the pressing member 100 consists of a series of double pantographs 151 and 152 superimposed vertically in the lateral slides 22 on either side of the slats 11.
- the pantographs 151 are connected to a fixed point of rotation 153 and to a pivot 155 movable vertically/transversely which is connected to the lateral activation rule 101, while the pantographs 152 are connected to the same pivot 155 movable vertically/transversely using of the lateral activation ruler and to a bearing pad axis 154 which is movable transversely.
- the vertical movement from bottom to top of the activation rule 101 causes the pivoting and extension of the pantographs 151 and 152 which push on the vertical plating rule 93 so that the vertical joint 92 in the form of a "U” comes compress the plug seal 91 and rest against the front walls 22f and dorsal 22d of each side slide 22 in order to ensure lateral sealing (FIG. 39).
- a reverse movement of the activation rule 101 upwards allows the springs 151 and 152 to return to their original position (figure 37) and therefore to separate the vertical joint 92 in the shape of a "U” from the plug joint 91
- means are provided to maintain the double pantographs 151 and 152 in each of the forward/backward positions.
- FIGs 40 and 41 very schematically illustrate a solution in which the pressing member 100 consists of a series of simple pantographs 161 with deformable parallelograms superimposed in the lateral slides 22 on either side of the slats 11 and used to moving the vertical U-shaped seal 92 away from or closer to the plug seal 91 using a method similar to those described above (alternating passage from one position to another to create/remove the lateral seal).
- the pantographs 161 are connected to a vertically movable pivot 165 which is linked to the lateral activation rule 101, and to a transversely movable axis 154.
- the upward vertical movement of the activation rule 101 causes the pivoting and extension of the pantographs 161 which push on the vertical plating rule 93 so that the vertical U-shaped joint 92 compresses the plug seal 91 and bear against the front 22f and back 22d walls of each side slide 22 in order to ensure lateral sealing (FIG. 41).
- a reverse movement of the activation rule 101 upwards allows the pantographs 161 to return to their original position (FIG. 40) and therefore to separate the vertical joint 92 in the form of a "U" from the plug joint 91.
- means are provided to hold the pantographs 161 in each of the forward/backward positions.
- FIG. 42 very schematically illustrates a solution in which the pressing member 100 consists of an expansive joint 171 by reversible expansion (change of volume) disposed between the front 22f, back 22d and bottom 22a walls of each side slide 22, on either side of the slats 11, and used to move the vertical U-shaped joint 92 away from or closer to the joint cap 91 according to a method similar to those described above (alternating passage from one position to another to create/remove the lateral seal).
- These expansion seals 171 can be chemical, pneumatic, or hydraulic expansion.
- FIG. 43 very schematically illustrates a solution in which the pressing member 100 consists of a bistable electromagnet 181 preferably disposed at the very top of the device 1, in the upper box 21, and which acts directly on the vertical linear displacement from top to bottom and from bottom to top of the lateral activation rule 101.
- the bistable characteristic of the electromagnet thus makes it possible to activate and return the pressing device with the same electromagnet, the only constraint being to have a sufficiently large thrust and return force to activate/recall all of the superimposed pressure systems, while having a limited footprint to be able to be installed.
- Figures 44 and 45 very schematically illustrate a solution in which the pressing member 100 consists of a double-stranded vertical ribbon 191 which extends along each lateral slideway 22 and which has first long transverse strands 192 connected each at the end of the long arm 104 of a bistable lever 103 and second short transverse strands 193 each connected to the end 105a of the short arm 105 of the same bistable lever 103.
- Tension springs 108 such as those already described previously allow the bistable function of the levers 103.
- the ribbon 191 is for example made up of a flat braid from which the long 192 and short 193 strands locally depart.
- Figures 46 and 47 show a variant of Figures 44 and 45 in which the ribbon 191 has only the long strand 192 connected to the arm 104 of each bistable lever 103.
- the tension spring 108 is under tension in the position vertical tackle ruler 93 and the tape 191 also moved back, so that the transition to the advanced position of the vertical tackle ruler 93 is effected by releasing said tape 191 which allows the lever 103 to pivot around the axis 106 and the approximation of the vertical seal 92 in the shape of a "U" of the plug seal 91 ( Figure 47).
- Means for keeping the ribbon 191 taut and for releasing it are of course provided but are not described.
- FIGs 48 and 49 illustrate an improvement of the invention in which each of the slats 11 is provided, near its two lateral ends 11c, with vertical grooves/grooves 19 cooperating with a rib/slide 24 (front and/or back) provided vertically along the two lateral slides 22 on the front wall 22f so as to guide the up and down movement of the shutter apron 10.
- This in particular allows the slats 11 not to move transversely, which could significantly reduce the sealing of the shutter apron 10.
- the vertical grooves 19 are arranged alternately close to the upper or lower longitudinal edge 11b of each slat 11, and they only extend over a portion of the height of each blade 11 due to the front curvature of the latter.
- FIGS. 50 and 51 show improvements to device 1 in which sixth lateral low-pressure sealing means IlOf and/or HOd consist, for example, of frontal vertical seals 200f and/or dorsal 200d in strips, are carried by the front walls 22f and / or back 22d of the side slides 22 and bear, in use, against the front face lOf and / or back lOd of the shutter apron 10.
- sixth lateral low-pressure sealing means IlOf and/or HOd consist, for example, of frontal vertical seals 200f and/or dorsal 200d in strips, are carried by the front walls 22f and / or back 22d of the side slides 22 and bear, in use, against the front face lOf and / or back lOd of the shutter apron 10.
- Figures 52 to 57 illustrate different embodiments of the fifth lateral sealing means 90.
- the fifth lateral sealing means 90 comprises two longitudinal sections 190 arranged respectively inside the two lateral slideways 22 (that is to say one section 190 per lateral slideway 22) and extending vertically on either side of the ends of the slats 11.
- Each longitudinal section 190 has a substantially crescent shape and is hinged around a pivot formed by a rigid rib 122 of the corresponding lateral slide 22.
- a first free end 190a of the longitudinal section 190 comprises a hollow housing 191' receiving a first lateral seal 195 (for example a hollow tubular elastomer seal) while the opposite end 190b of the said longitudinal section 190, arranged on the other side of the pivot 122, has the overall shape of a hook 194.
- the fifth lateral sealing means 90 also comprises a second lateral sealing seal 196 (for example also a hollow tubular elastomer seal) held in position in a hollow housing 126 of the slide 22 having substantially the same shape as said second seal. 196 in its unconstrained state.
- a second lateral sealing seal 196 for example also a hollow tubular elastomer seal
- Each longitudinal section 190 can rotate, around a virtual vertical axis located at the level of its contact with the pivot 122, between a first inactive position (FIG. 52) in which the first lateral seal 195 does not exert any pressure on the plug seal 91 of the slats 11 and at least one second active position in which said first lateral seal 195 exerts a first pressure on said plug seal 91 and the second lateral seal 196 exerts a first pressure against the housing hollow 126 of the lateral slide 22 as the pressure F is exerted on the front face lOf of the closure apron 10, in the lowered position of the latter, this in order to make the device 1 laterally sealed to said fluid when water tries to infiltrate on either side of the shutter apron 10 (remember that the interslat sealing is already set).
- each longitudinal profile 190 around the pivot 122 is caused by the displacement (recoil) according to the arrow D (FIG. 52) of certain slats 11 of the sealing apron 10 from the outside of the building 1 towards the interior of the latter thanks to an activation means 290 described in more detail later in relation to FIGS. 62.
- the slats 11 concerned by the fifth lateral sealing means 90 will be those located, once the shutter apron 10 has been completely lowered, for example less than approximately 1 m 20 from the ground , that is to say between approximately 12 and 24 slats depending on their average height.
- FIG. 53 illustrates a so-called “low” sealing position in which the slat considered 11 is moved back along the arrow D to cause the longitudinal profile 190 to pivot so that its first end 190a compresses the first lateral seal 195 against the plug seal 91 of the slats 11 and that the rear of the hook 194 of the second end 190b of the longitudinal section 190 compresses the second lateral seal 196 against the hollow housing 126 of the lateral slide 22.
- FIG. 54 shows a fifth lateral sealing means 90 in which the longitudinal profile 190 has a slightly different crescent shape which modifies the distribution of the compression forces of the lateral seals 195 and 196, of course retaining the same principle of pivoting rocker.
- FIG. 55 shows a fifth lateral sealing means 90 in which the second free end 190b of the longitudinal section 190 is provided with a hollow housing 197 to receive the second lateral sealing gasket 196 replacing the hollow housing 126 of the lateral slide 22, which then becomes a flat abutment surface 127 against which said second lateral seal 196 is crushed.
- Figure 56 shows a fifth lateral sealing means 90 in which the longitudinal section 190 is provided with an intermediate dorsal rib 198 located just before the pivot 122 of the lateral slide 22. This dorsal rib and located opposite the second seal of lateral seal 196 and compresses it little by little, from the second position of the longitudinal section 190, against an internal front wall 128 of the lateral slide 22 acting as a stop.
- Figure 57 shows a fifth lateral sealing means 90 in which the shape of the first free end 191 of the longitudinal profile 190 is modified to form a kind of spoon having a rounded zone 191” which comes to press directly on the plug seal 91, without the presence of the first lateral seal 195.
- Figures 58 and 59 show a system 200 for activating the translation movement (arrow D in figure 52) of the lower slats 11 and rotation (arrow R in figure 52) of the longitudinal sections 190.
- this activation system comprises two lower ramps 201 positioned against or inside each side slide 22, each ramp having an inclined plane 203 oriented upwards from the inside outwards (NB: of the building) .
- NB inside outwards
- this recoil movement of the slat causes the support of the inclined plane 292 of the groove 291 on the rounded end of the hook 194, which pivots (arrow R in Figure 52) causing the rotation of the entire profile longitudinal 190 and the crushing of the two side seals 195 and 196 respectively against the plug seal 91 and the slide 22 (recessed area 126, flat surface 127 or abutment 128).
- the activation system 200 also comprises a set of moving parts comprising an upper roller 210, preferably covered with a flexible sleeve 211 (elastomer), linked to one end of a slat 11 considered and adapted to take support on a lateral distribution plate 212, itself placed on a vertically movable longitudinal bar 214 which rests on a lower curved lateral plating plate 216.
- a set of moving parts comprising an upper roller 210, preferably covered with a flexible sleeve 211 (elastomer), linked to one end of a slat 11 considered and adapted to take support on a lateral distribution plate 212, itself placed on a vertically movable longitudinal bar 214 which rests on a lower curved lateral plating plate 216.
- the more the shutter apron 10 descends the more the lower slat 13 recedes thanks to the ramps 201, which causes the passage from the first position to the second position of the longitudinal sections 190. Furthermore, the more the shutter apron 10 descends, the more the rollers 210 press on the vertical bar so as to cause the side profiles to pivot and maintain them in their low then high pressure sealing position as the water rises against the front face lOf of the shutter apron 10 .
- each longitudinal profile 190 it is also possible to position a compression member (spring type) on each longitudinal profile 190 in its initial vertical position, for example fixed between the upper support roller 210 and the upper end of the profile.
- a compression member spring type
- the fifth lateral sealing means 90 preferably comprises an automatic water rise detection sensor so as to be able to automatically trigger (without action by an individual) the activation of the pressing member so as to create the lateral seal.
- a humidity sensor of known type can be used. This sensor can also be used upstream to actuate for the rotation of the shutter so that it descends completely, then its locking in the lower chute.
- An anemometer can also be used for the same function of automatic activation of the shutter in the event of a storm.
- this anti-flooding device is destined to be activated without constraints and this for any absence of person in the protected premises. It is not a priori necessary to have an external electrical source to protect the building at the time of flooding: all the seals are mechanically passive (no mandatory dependence on sensors).
- the layout necessary to implement the device is light, and can be done on new construction as in renovation. It requires grooves of a few centimeters in section in the floor and in the side walls, to insert the side guides and the lower chute.
- this device has a subtle balance between a significant stiffness, which allows it to resist the thrust of the water over a significant height (1.5m water height for a 1.8m wide opening for example, which was totally inconceivable to obtain with the solutions of the Prior Art), a dissociation of the slats allowing flexibility of these and unhindered winding, and double sealing, low pressure for small water heights, and high pressure, called passive, which increases when the height of water, and therefore the frontal pressure exerted on the sealing apron, increases.
- the inter-slat waterproofing is placed in the slats, and therefore does not present any mechanical weakness.
- the apron must be very rigid to withstand water, and very flexible to be able to roll up.
- a seal must have flexible parts, which conform to each other, in contradiction with the need for stiffness of the deck.
- the shape of the joints, the profiles of the slats, the number of springs or even levers can vary according to the needs, the geography of installation of the device and the risks incurred (areas more or less liable to flooding, subject to storms and / or intrusion), the dimensions of the opening (height and width) and therefore those of the shutter apron 10.
- a flexible cord can optionally be inserted at the rear of the lower slat 13, which comes crashing against the rear of the lower gutter when the water rises, improving the high pressure seal.
- the pressure shoe 107 can be mounted on a ball joint to best conform to the shape (and any deformations) of the vertical plating rule 93.
- a system of lateral wedges sliding vertically in the wings 22 can be used to move the vertical tackle rule 93.
- the pressing system could be actuated occasionally, and not each time the shutter is lowered, either by a command that the user voluntarily activates (for example, another position in the shutter closing command: open, partially closed , fully closed but without waterproof mode, fully closed with waterproof mode), or by a command triggered when the water level rises.
- This passive triggering of the actuation could be of several types, either using a float-type sensor connected to an electric actuator (the float, driven by the rising water, would trigger the locking command, or using a conduction sensor connected to an electric actuator (the presence of water would close and no longer open an electric circuit, thus allowing actuation of the locking control).
- the device is suitable for sectional garage or warehouse doors, which therefore often have large widths (2 to 5 m for example) and much higher slats (10-50 cm).
- the device can also be sized to withstand extremely high gusts of wind exceeding 200 km/h and/or water heights exceeding 1m50 to 1m80. For this, it will be necessary in particular to adapt the size of the joints and the slats.
