Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a flexible shutter for closing an opening. More particularly, the present invention relates to a shutter device for closing an opening, comprising: 'at least one slide; a deformable shutter movable across the opening in a direction to cover the opening or Moving in the opposite direction to expose the opening, the shutter package includes at least one side bead slidably mounted in the slide and can be withdrawn therefrom by a defined pulling force, the pulling force Transversely pointing to the slide; and - a member for re-embedding the bead that has been withdrawn from the slide into the slide, the member comprising a guide member positioned to face the slide and drummed It is calculated that when the shutter is moving in the opposite direction as described above, it deflects the edge of the bead that has been extracted from the 6-slide into the slide. [Prior Art] ® Deformable shutters are commonly used to close openings, especially for closing warehouses or industrial halls. Such shutters are typically made of a large flexible tarpaulin whose side edges include bead rims that slide in the slide, which are located on each side of the opening to be closed. The side bead edges of the shutter are telescopic in the slide so that they are detached from the slide if subjected to a tensile force exceeding a defined threshold and directed laterally to the slide. The purpose is to prevent any damage to the shutter in the event of an accidental impact, for example, which may occur when the vehicle accidentally rushes into the shutter 9 141008.doc 201014962 where it is accidentally flushed. Such shutters require that the side bead edges, which may have been accidentally pulled out, be re-inserted into the slides' to restore the use of the shutters. Document ΕΡ Α 0 272 733 describes a type of shutter device of the above type in which a member is provided to automatically re-embed the side bead of the shutter into the slide. The cattle are included in the longitudinal direction of the slide to make a side bead that may have detached from the slide as it rises, returning to the slide as it reaches the hole. Document WO 03/048498 improves the insertion of the article ερ_α 〇 272 733. In the shutter device of the document WO 03/048498, the member which immerses the side bead of the shutter into the slide, in addition to the hole Φ, comprises a guide block located at each side of the shutter and facing one of the openings. The blocks are positioned on each side of the shutter and are separated from each other by a distance between the thickness of the shutter and the thickness of the bead. The blocks are positioned toward the aperture of the slide such that during the upward movement of the shutter, the bead (which has detached from its slide) slides against the guide tabs of the two guiding bead edges, thereby Push it back into the hole in the slide. In this known shutter device, the sliding of the bead of the shutter on the two blocks produces a frictional force acting as a load on the shutter and hindering its upward movement. In the devices of the documents ΕΡ·Α 0 272 733 and w〇 〇3/〇48498, which have just been described, a hole must be made in the slide which is wide enough to allow the bead to re-embed into it. SUMMARY OF THE INVENTION The present invention is directed to an improved shutter device that avoids the lack of friction associated with the shutter against the guide block when it is re-inserted into the slide. 141008.doc • 4 - 201014962 To this end, according to the present invention, the bow member includes at least a pair of rollers that are respectively positioned on each side of the shutter such that when the shutter moves in the opposite direction, the edge is self-sliding The trailing edge of the ball rolls to push it into the slide. Ο In this article, the term “opening” means forming a hole in a wall or a partition of a building, or forming a hole in the ground. The opening may be a vertical opening (eg, a door or window formed by a vertical wall of a building - a vertical opening), a horizontal opening (eg 'passing the ground or passing through to provide a chamber or a cavity entrance) a hole formed by the horizontal roof structure of the building, or alternatively an obliquely directed opening (for example, a hole formed through the inclined roof portion). The invention is particularly suitable for vertical opening D. The shape of the opening is not critical. The upper opening is generally square or rectangular. The size of the opening is also not critical. The invention is particularly applicable to vertical openings that are sized to allow land vehicles (eg, motor vehicles, trucks, semi-trailers or trailers entering a merchandise warehouse, 2 industry workshops or exhibition halls), aircraft (eg, aircraft at ground repair stations) Or river vessels (for example, barges entering the unloading warehouse) pass (this list is not exhaustive and is given by way of example). The invention is also applicable to horizontal openings formed through the ground such openings, for example, defining pools, lakes or sinks for storing and/or processing industrial materials (this list is not exhaustive and is given by way of example ). In the broadest sense, the term "shroud" means a separator that is at least partially flexible or easy to remove. For example, the shutter may comprise a collection of straps hinged 141008.doc 201014962, tarpaulin, gauze or grid (this list is not exhaustive and is given by way of example). It can be completely or partially opaque, transparent or translucent. It may be made of a metal or a (co)polymer obtained by chemical synthesis, such as polyethylene, which may be reinforced with an organic material (e.g., glass fiber). A flexible tarpaulin is preferred. In the device according to the invention, the shutter is designed to cover the opening or expose it arbitrarily in a manner known per se. To this end, the shutter can be made to move across the opening in the opposite direction, i.e., covering the opening in one direction and exposing it in the opposite direction. In the rest of the text, the expression "opposite direction" means that the direction of the shutter β is in the direction in which the shutter gradually exposes the opening. The slide is used to guide the shutter during movement of the shutter in the two opposite directions. The slide can be generally straight and positioned along the opening. The shutter is guided by at least one of its bead edges that are slidably mounted within the slide. The shape of the bead edge is adapted to match the shape of the slide in cross section such that it is retained therein and is slidable therein during movement of the shutter through the opening. Despite this general condition, the shape of the bead is not critical to the definition of the present invention. For example, the bead may have a circular or polygonal cross-section such as a square, rectangle or hexagon. A circular cross section is preferred. The bead can form an integral part of the shutter. As an alternative, it can be attached to one of the edges of the shutter and secured thereto by any suitable means, such as by bonding, welding or beveling. The bead may be continuous or toothed and extend over the entire length of the side edges of the panel. As an alternative, the shutter may comprise a spacing along the side edge of the shutter 141008.doc 201014962. In the rest of the text and unless otherwise stated, the term "bead edge" will be indiscriminately represented. A continuous or toothed side bead edge or a few bead edges on one side. (d) The track generally has a cross-section that matches the cross-section of the bead and is pierced through a longitudinal slit through which the shutter can pass. It may be made of any material suitable for its technical function, such as earth metal or made of a (co)polymer obtained by chemical synthesis, for example made of high density polyethylene 'possibly with organic materials (eg glass fibers) Enhanced.

In the case of a slanted opening, the slide is generally inclined. In the case of a vertical opening, the slide can be vertical or horizontal depending on the selected direction in which the shutter moves. The slide is vertical when the shutter is moved vertically to open or close the opening π. The slide is horizontal when the shutter is moved horizontally to open or close the opening. The position of the side bead on the hood is determined by the position at which the side bead cooperates to guide the slide of the visor. The bead and the slide are designed and formed in such a manner as to allow the bead to be pulled out of the chute when it is laterally pulled (within a reference value) through a plane that is directed toward the shroud and opposite the chute. . In the definition of the invention, the expression "plane of the shutter" is intended to mean an imaginary geometric plane defined by the shutter when it covers the opening. 141008.doc 201014962 Pulling the bead from its chute under the force described above must occur without damaging the visor, bead or slide. The profile and size of the slide and bead and its ability to withstand deformation must therefore be tailored so that the pulling force required to pull the bead out of the chute is less than an easy to tear mask or damage to the chute or bead Threshold value. However, the pulling force must be substantial enough to prevent the bead from accidentally coming out of the slide during normal operation of the shutter. Additional information on shutters, slides and bead edges is available in the literature ΕΡ Α 272 272 733 and WO 03/048498 (both under the name Dynaco Internati〇nal). The shutter device according to the invention is also provided with a member which is designed such that when the bead has been pulled out of its slide, in the direction in which the shutter is exposing the opening (defined above as "opposite direction") While moving, the beads are automatically reintroduced into them. According to the invention, the member comprises at least one pair of rollers respectively positioned on each side of the shutter such that when the shutter is moved in the opposite direction (in the direction of the exposed opening), the roller edges are The trailing edge of the slide is rolled and pushed into the slide. In the shutter device according to the present invention, the position of the roller toward the slide is very important. It must be chosen such that when the shutter is moved in the opposite direction, the rollers rotate on the bead (which has been pulled out of the chute) and force it through the longitudinal slit in the chute to enter the slip Road. In order to enhance this action of the roller, it is proposed in an advantageous embodiment of the invention to have the surface of the roller with rib edges. It gives the roller a better edge to grab #力. In the device according to the invention, the spacing between the two rollers must be greater than the thickness of the shutter (so that it does not interfere with its movement through the opening) and less than the thickness of the bead (to force its 141008.doc 201014962 on it) ). A considerable spacing is normally left between the roller and the slide. Ideally, this spacing needs to be small enough that the tension applied by the roller to the bead is sufficient to reinsert the latter into the slide. However, it is necessary to avoid having too small a spacing, for which the rollers, beads and slides should be subjected to excessive mechanical forces. Therefore, the optimum spacing must be determined by those skilled in the art to suit each particular environment. According to a particular embodiment of the shutter assembly of the present invention, the spacing between the rollers is adjustable. This embodiment is suitable for use with a mask having different thicknesses. In another particular embodiment of the invention, a bore is formed in the slide that faces the roller. In this embodiment of the invention, the purpose of the aperture is to reduce the force applied to the bead when the bead is reinserted into the slide. In this embodiment of the invention, the roller is partially engageable in the aperture of the slide to continue rolling along the bead, even when the bead is normally in the proper position within its slide. However, for the above reasons, it is preferred to maintain a substantial spacing between the roller and the bead. In the shutter device according to the invention, the roller can have any shape that is compatible with its technical function. In the shutter device according to the present invention, the rollers are positioned relative to each other with respect to the plane in the shutter (the plane in the shutter is defined above). Preferably, the rollers are symmetrically positioned within the shutter. The female side 0 is mounted on the shutter in accordance with the present invention, and the rollers include axes of rotation that are positioned relative to one another relative to the mid-plane of the shutter. In the preferred embodiment of the present invention, the fixed rotational axis of the roller is symmetrical. 141008.doc 201014962 is located on each side of the plane in the plane. In this embodiment of the invention, the two axes of rotation of the two rollers are preferably located substantially in the same geometric plane, and the plane is preferably substantially perpendicular to the plane of the shutter. In another preferred embodiment of the invention, the two rollers converge toward the slide. With all other factors remaining the same, the optimal convergence angle of the two rollers is compromised, seeking to obtain the maximum force applied by the roller to force e to be pulled. The towel has a compromise between seeking to achieve the minimum wear of the roller, the bead and the slide. Therefore, the optimum convergence angle must be determined by the skilled person according to the environment for each specific situation. The roller is favorably female. Mounted to rotate on a ball bearing or other similar rolling contact bearing. In the shutter device according to the invention, the roller must be mechanically strong enough to withstand the mechanical forces applied to it by the shutter. Despite this condition For the purposes of the present invention, the size of the roller and the material from which it is made are not critical. For example, the roller may be made of a metal (such as steel) or a (co)polymer obtained by chemical synthesis (eg, polyester, Polyamide or elastomer.) In a particular embodiment of the invention, the 'slide is provided with a reinforcing member in its region adjacent the roller. In this embodiment of the invention, adjacent The area of the roller is typically located in a region very close to the roller, and the movement in the opposite direction of the shutter relative to the shutter is downstream of the roller. Advantageously, the reinforcing member can include the slide in one of the jaws. The crucible section may be made of a metal such as steel or by (co)polymerization of high mechanical strength 141008.doc 201014962, such as, for example, polyamine. In an advantageous alternative form of one of the embodiments just described The roller is fixed to a frame containing the u-shaped section. This alternative form of the invention allows the roller to move freely along the slide. It also makes it easier to change the roller, for example if the roller becomes worn or damaged. To this end, in this alternative form of the invention, it is advantageous to secure the frame and the slide to a fixed support, such as along the opening and cemented to a suitable structure (eg, a stone structure) Metal frame in the interior. In a particular embodiment of this alternative form of the invention, the frame comprises an axial passage and a U-shaped cross section formed by the axial passage At least a portion. In this embodiment of the invention, the frame is advantageously obtained by molding. In the device according to the invention, the shutter may comprise a single slide and cooperate with the slide to guide the One of the shutters has a single bead.

The re-embedded element according to the invention can be easily assembled to the j-shielding device according to the invention. It can be farmed to the existing shutter that is included in the guide slide sliding U-bead. When the re-embedded component according to the present invention is mounted on an existing shutter, the frame of the re-embedded component is directed in such a manner as to be positioned downstream of the above-mentioned channel in the opposite direction to the above definition. The invention has many applications, in particular for closing large vertical openings for hangars or warehouses for importing 141008.doc •12· 201014962, or for covering water filled tanks (eg industrial water treatment tanks or tanks)' Or alternatively it can be used to cover horizontal openings that provide access to silos or other spaces where goods or industrial products are stored. [Embodiment] 圊 1 to 3 show a vertical opening 1 of a vertical partition wall 2 penetrating a building such as an industrial or commercial warehouse. The size of the opening 允许 allows a truck (not shown) to pass. The partition wall 2 is equipped with a shutter device according to the present invention. The shutter package includes a shutter 3 formed of a flexible tarpaulin, for example made of fiberglass reinforced polyethylene. The shutter 3 is fixed at its upper portion to the horizontal cylinder 4 above the opening i. The barrel 4 is coupled to the motor 5, and actuation of the motor causes the shutter to be lowered in March to cover the opening 1 and close the building, or to be raised to expose the opening 1 and allow a truck to pass. A pair of vertical slides 7 and 8 are respectively disposed along the vertical edges of the opening 1. The slides 7, 8 are fixed to a metal frame 9, which is fixed in the ground 6 by cement. The slides 7, 8 are used to guide the shutter during the ascending and descending movements. The hinge 3 is provided with two side beads 10 and 11 which are in the slides 7 and 8. . In Fig. 4, the bead edges 1 and 11 have a circular outline and have a thickness greater than the thickness of the shutter 3. The slides 7 and 8 are formed by a cross-section of a circular cross-section that extends from the two flanges 12 and 13 and defines a vertical longitudinal slit 16 between the flanges. The width of the slit 16 is approximately somewhere between the thickness of the flexible tarpaulin of the shutter 3 and the thickness of the bead rim & U. Therefore, when the shutter 3 is lowered or raised, the bead edge is cut and the crucible slides in the slides 7 and 8. Each of the slides 7 and 8 is disposed within the frame 14, which will be explained later. 141008.doc 13 201014962 The slides 7 and 8, in particular the flanges 12 and 13 thereof, are designed such that once the tensile forces X and Y (Fig. 4) are applied to the bead in the plane of the shutter and laterally directed to this At the time of the slide, the beads 10 and 11 can be detached from the slide via the slit 16. For example, this may occur when the shutter is lowered or not fully raised and the vehicle entering or leaving the warehouse is violently struck. It is advantageous to have the tensile forces X, γ required to pull the beads 10, 11 out of their respective slides 7 and 8 as large as possible to prevent the beads 10 and 11 from leaving them arbitrarily when the shutter 3 is operated. Slides 7 and 8. However, this pulling force still needs to be lower than a critical value to prevent the tarpaulin of the shutter 3 from being torn. Figure 5 shows that the bead 10 of the shutter 3 has been pulled out of its slide 7. For example, the slides 7 and 8 are made of high density polyethylene. The shutter device shown in the figures is equipped with an element according to the invention for re-embedding the bead 1 (or bead 11) after it has been pulled out of the slide 7 (or 8). The device, which is more clearly depicted in Figures 6 to 10, comprises a frame 14, which is fixed to the frame 9 above the slide (Fig. i & 3). The frame 14 is penetrated by a constant axial passage 15, the u-shaped profile of which allows the slides 7, 8 to be placed therein. The frame 14 is advantageously molded from a body of high strength plastic such as polyamide. In Figures 6 to 10, the slide 7 is disposed in the passage 15 of the frame 14. The frame 14 has a function of improving the rigidity of the slide 7 provided therein. To this end, the frame 14 has two longitudinal flanges 21' supported on the flanges 12 and 13 of the slide 7, respectively. When the bead is reinserted into the slide in a manner to be explained later, the frame 14 and its flange 21 must be sufficiently rigid to prevent any deformation of the slide 7 within the frame 14. 141008.doc •14· 201014962 A sufficient space is required between the two flanges 21 to allow the shutter 3 to pass. The frame 14 is provided at its lower portion with a pair of rollers 17, which are mounted on a ball bearing shaft 18 which is disposed on the fixed shaft 19. The axes 19 are oriented such that the two rollers 17 are symmetrically located on each side of the axial plane of the runner 7: very close to the slot 16 of the runner 7. Further, the roller 17 is positioned near the lower end of the frame 14. Therefore, the frame is located downstream of the roller 17 with respect to the direction in which the shutter 3 is lifted. ^

The two rollers 17 face the slit 16 of the slide 7 and converge toward the slit 16. The spacing between the two rollers is selected to maintain a sufficient distance A between each roller 17 and the shutter 3 without hindering the normal operation of the shutter, while at the same time preventing the bead 10 of the shutter from being on the roller 17. Sliding over. In addition, the roller 17 is positioned in such a manner that a relatively large spacing B between the roller & the bead 10 is maintained as the bead 1G slides within its slide 7 in a normal manner. The figure shows an advantageous embodiment of the invention wherein the roller has ribs on its periphery. When the bead is reinserted into its slide in a manner explained later, the rib 22 of the roller 17 enhances the grip of the roller against the bead. The re-embedding mode of operation in accordance with the present invention will now be explained with particular reference to 14. In Fig. 11, it can be seen that the bead edge 1 of the shutter 3 is sprinkled in a normal manner. Therefore, when the bead edge is subjected to the upward or downward movement in the direction of the arrow Ζ·Ζ•, the bead 1G normally slides in its slide 7 to guide the shutter. H1008.doc •15- 201014962 A hole 23 has been cut in the slide 7 facing the roller 17. This hole 23 has been cut out in the flanges 12 and 13 of the slide 7. Figure 12 shows a substantial spacing B between the roller 17 and the bead 1〇. Therefore, when the shutter 3 is normally operated, the bead is not loaded by the roller 17. In Figures 13 and 14, the bead edge 1 of the shutter has been pulled out of its slide 7. By subjecting the shutter to an upward movement in the direction of the arrow Z, the bead 1 被 is pulled upwards in the direction of the arrow z and travels past the roller 17, by which the roller is pushed in the direction of the arrow c The edge 1 进入 enters the slide 7 through the hole 23» Figure 14 shows the force applied by the roller 17 to the bead 1 图 Figure 15 shows the bead 27 of the visor 3, which is on each side of the plane in the visor 3 Has a toothed shape. Advantageously, the toothed bead 27 is provided with a continuous shoulder 28 which provides a continuous contact bearing area for the roller 17. To make the figure clearer, the slide 7 is not shown. In Fig. 16, it can be seen that the re-embedded component according to the invention is incorporated into a shutter device. The shutter device comprises on each side a deflection pulley 24 which allows one of the directions in which the shutter 3 changes direction, such as The deflection pulley 24 is mounted for rotation and fixation, for example, by a shaft (not shown). Where appropriate, the deflection pulley 24 can drive the shutter 3°. The re-insertion element has a curved portion with a guide roller 25. The guide roller is intended to keep the toothed bead 27 in line with the return pulley 24 and Keep it in the channel 15 or slide 7, regardless of the direction of the slide. In describing the drawings, it has been assumed that the opening 1 is vertical and the shutter is suspended from a barrel 4 disposed above the opening. In this embodiment, the shutter is moved upward to expose the opening. 141008.doc 201014962 However, the invention is also applicable to the case where the cartridge 4 is located at the bottom of the opening 1. In this modified embodiment of the invention, for example, the cartridge can be housed in a channel below the ground plane. In this embodiment, the shutter is moved downward to expose the opening and move upward to cover the opening. In another modified embodiment of the invention, the runner 7 is horizontal and positioned along the upper horizontal edge of the opening 1 and the runner 8 is disposed along the horizontal edge of the lower opening. In this embodiment of the invention, the beads 10 and 11 of the shutter 3 are horizontal and the barrel 4 is vertical and disposed along one of the vertical edges of the opening 1.
