Definitions

  • the present invention relates to a liftable curtain door with improved lateral tightness, intended to reduce the passage of air through the door, to limit heat exchange and / or the entry of dust or microorganisms into a room.
  • Such doors generally comprise two lateral uprights provided with slides in which the lateral parts of the curtain slide.
  • European patent n ° 0 194 194 describes a technical solution making it possible to avoid the passage of air between the slides and the lateral parts of the curtain.
  • the side uprights are U-section profiles which have a bottom wall substantially perpendicular to the curtain, and two side walls which extend from the bottom wall towards the curtain, parallel to the curtain.
  • the side edges of the curtain are extended by a strip of flexible material which rubs against the bottom of the U-shaped profile.
  • the document EP 0 033 199 describes a liftable curtain door having a flexible rubber curtain provided with thick side edges which slide in slides.
  • the slides have a constriction arranged between the thick edge of the curtain and the opening to be closed.
  • This type of door is particularly intended to produce a substantially sealed closure between sections of a mine which are maintained at a determined pressure.
  • the thick edges of the curtain are deformable so as to pass through the throttle of the slide during a violent impact on the curtain. But in such a case, the thick edge of the curtain may get stuck in the throttle of the slide, which subsequently prevents the curtain from being raised and blocks the door in the closed position.
  • the object of the present invention is to remedy this drawback.
  • the subject of the present invention is a flexible curtain door which can be raised to close a bay, comprising two lateral uprights each having a slide forming a constriction, the curtain forming substantially a plane and comprising lateral edges which slide in said constriction and which are provided with reliefs protruding out of the plane of the curtain, said reliefs being arranged in a substantially continuous manner along the lateral edges of the curtain and being adapted to be applied in a manner substantially tight against the throttling of the slides at least when the curtain undergoes a tensile force directed towards the interior of the opening, said reliefs having sufficient flexibility to pass through said constriction when said tensile force exceeds a determined value, characterized in that that said reliefs are constituted by a flexible elastic sheet material secured to the lateral edges of the curtain, and said sheet material extends diverging from each lateral edge of the curtain, on each side of the plane of the curtain.
  • the side edges of the curtain can be deformed to have a very small thickness so that they are not likely
  • the sheet material may comprise two lateral sheets each integral with said lateral edge of the curtain, and each extending from one side of the plane of the curtain diverging from the lateral edge of the curtain, or it may comprise a single sheet formed in loop, which constitutes a hollow bead secured to the side edge of the curtain.
  • said sheet material can extend continuously along each lateral edge of the curtain.
  • said sheet material may include horizontal cutouts to facilitate the deformation of the curtain out of its plane, for example during winding on an axis during the raising of the curtain.
  • said constriction of the slide of each upright comprises ribs directed towards said sheet material, which extend continuously parallel to the lateral edge of the curtain, and which are adapted to be applied in substantially sealed contact against said sheet material, at least when the curtain undergoes a tensile force directed towards the interior of the opening.
  • said sheet material has ribs directed towards the constriction of the post slide, which extend substantially continuously parallel to the lateral edge of the curtain. and which are adapted to be applied in sealed contact against said constriction, at least when the curtain undergoes a tensile force directed towards the interior of the opening.
  • said sheet material has reliefs facing the throttle of the upright slide, and said throttle comprises reliefs against which said reliefs of sheet material abut when the curtain undergoes a pulling force directed towards the interior of the bay.
  • said constriction of the slide of each upright comprises sliding pads or rolling means arranged at a certain distance on each side of the plane of the curtain, facing the sheet material.
  • said sheet material comprises sliding pads or rolling means arranged at a certain distance on each side of the plane of the curtain, opposite the throttle of the slide of each lateral upright.
  • the door according to the invention has two lateral uprights 1, 2, which generally frame an opening 5 open in a wall 9 of a building.
  • the lateral uprights 1, 2 each comprise a slide forming a constriction 7 in the vicinity of the opening 5, the constriction 7 delimiting a vertical slot 8.
  • the vertical lateral uprights are profiles, for example metallic, having a U-shaped section.
  • the throttle of the slide consists of a front wall 7 from which extend two walls 10, towards the outside of the opening 5, but the uprights 1, 2 could have any other shape without departing from the scope of the present invention, provided that they have a throttle 7.
  • the door of FIG. 1 also has a lifting curtain 4, which has lateral edges 4a sliding in the slot 8 of each lateral upright.
  • the curtain 4 is flexible, so that, when a force is applied to it perpendicular to its plane, this force results in a traction on the lateral edges 4a of said curtain, which tends to cause said lateral edges 4a to come out of the slots 8
  • the curtain 4 also includes reinforcing bars 6 horizontal. It is essential that these bars have sufficient flexibility to allow the edges 4a to come out of their slot 8 when a sufficient force is applied to the curtain 4 perpendicular to its plane, for example during an impact of a handling vehicle against the curtain 4.
  • the door further comprises a cross member 3 which connects the lateral uprights 1, 2 at their upper ends.
  • a cross 3 could possibly be omitted without departing from the scope of the present invention.
  • the door curtain according to the present invention can be raised in various ways.
  • the curtain 4 can be raised by winding around a horizontal axis 11 located in the upper part of the door.
  • the lateral uprights 1, 2 of the door can be extended in the upper part by slides 15, 16 in which the lateral edges 4a of the curtain 4 can slide. In the latter case, the curtain 4 is raised without winding, by simple sliding in the slides 15 and 16.
  • the curtain 4 can be actuated by mechanical or electromechanical means which are well known in the state of the art.
  • each lateral edge 4a of the curtain 4 of the door may comprise two sheets of elastic flexible material 20, 21 which extend continuously over the entire height of the lateral edge 4a, each of 'one side of the curtain plane.
  • Each of the sheets 20, 21 is integral with the lateral edge 4a of the curtain, and extends from said edge 4a in a direction not parallel to the plane of the curtain 4.
  • the lateral edge 4a of the curtain thus has a Y-shaped section or from T.
  • the flexible sheets 20, 21 may each comprise a part parallel to the plane of the curtain, respectively 20a, 21a, and a bent part, respectively 20b, 21b, not parallel to the plane of the curtain.
  • this angle can be different from 90 °, provided that it is not equal to 180 °.
  • Each part parallel to the plane of the curtain 20a, 21a is fixed to the curtain by any known means, for example by sewing, welding, gluing, hot pressing, etc.
  • the sheets 20, 21 can be fixed to one another in the vicinity of the junction 22 between their parts parallel to the curtain and their bent parts.
  • the sheets 20, 21 can thus be formed in one piece.
  • the bent portions 20b, 21b of each flexible sheet 20, 21, may include horizontal slots 23, distributed over the height of the side edge 4a of the curtain. This facilitates the deformation of the curtain 4 out of its plane, for example when the curtain 4 must be rolled up when it is raised.
  • the curtain 4 is then wound on a roller 24 rotatable about an axis 11. It may be advantageous that the width of the roller 24 is equal to or slightly less than the width of the curtain 4 itself , so that the bent parts 20b, 21b of the flexible sheets 20, 21 wind up outside the axial ends 25 of said roller 24. This prevents said bent parts 20b, 21b from creating local excess thicknesses in the winding of the curtain.
  • FIG. 9 represents the arrangement of the lateral edge 4a of FIG. 7 when it is inserted into a slide formed by a constriction 7 of a lateral upright 1.
  • the edge lateral 4a does not undergo any pulling force towards the interior of the opening 5.
  • the bent parts 20b, 21b of the flexible sheets 20, 21 are slightly deformed towards the outside of the opening 5 , so that their respective free end 20c, 21c is in elastic contact against the throttle 7 of the upright.
  • said sheets 20, 21 make a sealed contact between the curtain 4 and the lateral uprights 1, 2, without the friction between said sheets 20, 21 and the constriction 7 being significant.
  • said sheets 20, 21 rub against the constriction 7 only by their free ends 20c, 21c, so that the friction surface is limited.
  • the door according to the invention ensures that there is substantially no significant passage of air through the opening 5 when the curtain 4 is lowered.
  • the bent parts 20b, 21b of the flexible sheets 20, 21 may include ribs 27 parallel to the lateral edge 4a of the curtain. These ribs 27 are directed towards the constriction 7 of the lateral upright and are adapted to apply elastically in a sealed manner against said constriction 7.
  • the ribs 27 limit the contact surface between the flexible sheets 20, 21 and the constriction 7, and therefore also limit the friction between said flexible sheets 20, 21 and the constriction 7 when the curtain 4 slides.
  • the constriction 7 of each upright 1, 2 may optionally include ribs 28 parallel to the lateral edge 4a of said curtain and directed towards the sheets 20, 21 of said lateral edge 4a, on each side of the plane of the curtain 4.
  • These ribs 28 also have the effect of limiting the friction between the constriction 7 and said sheets 20, 21 during the sliding of the curtain 4.
  • the ribs 28 of the throttle 7 may be formed in one piece with said constriction 7, as shown in FIG. 17, or else, as shown in FIG. 18, the ribs 28 may be seals made of rubber or of another flexible material, attached to the throttling 7.
  • the bent parts 20b, 21b may be advantageous for the bent parts 20b, 21b, to have in the vicinity of their respective free ends 20c, 21c rollers adapted to roll vertically against the throttle 7, while maintaining a spacing between said bent parts 20b, 21b and the constriction 7, when no tensile force is applied to the curtain 4.
  • this configuration there is no sealed contact between the flexible sheets 20, 21 and the constriction 7 of each side door jamb. Thanks to the rollers 29, any friction between the flexible sheets 20, 21 and the constriction 7 of each lateral upright of the curtain is substantially eliminated, which results in an appreciable gain in energy.
  • rollers 29 could be arranged on the constriction 7 instead of being disposed on the bent parts 20b, 21b of said flexible sheets 20, 21.
  • the rollers 29 could be replaced by sliding shoes 30, which can be arranged on the bent parts 20b, 21b of the flexible sheets 20, 21, in the vicinity of their respective free ends 20c , 21c.
  • the sliding pads 30 can be arranged on the constriction 7, like the rollers of FIG. 21.
  • the lateral edge 4a of the curtain can be fixed to a single elastic flexible sheet 26 formed in a loop and s' extending longitudinally along the lateral edge 4a of the curtain.
  • the flexible sheet 26 has two ends 26a and 26b which are fixed to the lateral edge 4a of the curtain, by any known means.
  • the flexible sheet 26 departs from the plane of the curtain 4, on each side of said plane of the curtain 4, so that the lateral edge 4a of the curtain locally has a Y-shaped section, as it was previously seen.
  • the curtain 4 shown in Figure 12 therefore behaves in exactly the same way as the curtain described above, and it is capable of the same variants.
  • the curtain 4 has horizontal reinforcing bars 6 which slide in the lateral uprights 1, 2, these bars are generally threaded in sheaths formed in the curtain 4.
  • this fixing is done for example by sewing or by hot pressing, it risks locally obstructing the sleeves intended to receive the bars 6.
  • the solution shown in FIG. 13 can be used.
  • the lateral edge 4a of the curtain comprises a single flexible sheet 26 formed in a loop and fixed by its two ends 26a at the edges of the curtain 4.
  • the sheet 26 extends along the side edge 4a of the curtain, but it is interrupted at each horizontal bar 6.
  • seals 31 one of which is shown in FIG. 14.
  • Each seal 31 has a front part 32 adapted to fit onto the end 6a of the bar 6, and a rear part 33 which may comprise two elastic flexible sheets 34, 35 extending from the front part 32 towards the outside of the curtain 4, diverging on each side of the plane of the curtain 4.
  • the rear part 33 is adapted to be applied in a sealed manner against the constriction 7 of the slide in which the lateral edge 4a of the curtain slides.
  • the rear part 33 could comprise a single flexible sheet formed in a loop and fixed at its two ends to the front part 32.
  • the front part 32 of the seal 31 comprises two elastic sheets 35, 36 joined at a rear end 37, and which are adapted to be fitted onto the side bars 6 and the curtain 4 from the side edge 4a of the curtain, by elastically tightening said bars 6 and said curtain 4.
