Definitions

  • the present invention relates to lifting curtain lifting doors, of the type comprising a rigid frame formed by two vertical lateral uprights, joined to their upper parts by a cross member.
  • This type of door is intended to be placed around a bay formed in a wall, to open or close said bay.
  • the closure is achieved by a curtain, which can descend between the uprights or be raised to be picked up at the top under the cross member, or in it, or on one side thereof.
  • the curtain can be formed from a flexible sheet, or from rigid panels hinged to each other, the curtain being reinforced by horizontal bars, which if necessary can be used as hinges, and whose ends slide to be guided, in runners formed by, or arranged in, the uprights.
  • the cross member When raising the curtain, it can be rolled up in the crossmember, or fold back in accordion under the crossmember, or be offset laterally between guide rails.
  • the cross member generally has a U-shaped section open at the bottom.
  • the mechanical members for actuating and controlling the operation of the door are placed in the crossmember, for example, a curtain winding shaft or lifting straps, an electric motor, a limit switch, etc. Examples of such actuators are described in patents EP-0 254 639 and US-4 828 003.
  • the object of the invention is to provide a removable sealing device for a lifting door with a lifting curtain allowing, in all conditions, easy access to the door mechanics while ensuring the sealing of the fixed part of the door in all conditions. , especially when the door is closed.
  • the subject of the invention is a sealing device for a lifting door with a lifting curtain, comprising a rigid frame formed by two vertical lateral uprights joined at their upper parts by a cross-member with a U-section open downwards, having a core and two wings which extend downwards to a lower edge and sheltering mechanical operating elements of the curtain, and a curtain which can be lowered or raised between the uprights, said curtain comprising an upper part, characterized in that the part top of the curtain is located at a certain distance below the bottom of the cross, below the mechanical members if necessary below the cross, and a cover having two parallel longitudinal edges, an upper edge and a lower edge, is hung by its upper edge on the lower edge of a wing of the cross member, and is kept in an orientation such that its lower edge is placed against the upper part of the curtain, so as to ensure a continuous closure between the cross member and the curtain.
  • the upper part of the curtain is stationary, and said upper part is fixed to a bar extending between the uprights, at a distance from the bottom of the crosspiece making it possible to place the mechanical actuating members of the curtain between this bar and the bottom of the cross member, and the lower edge of the cover is applied against the fixed upper part of the curtain.
  • the fixing bar can in this case be fitted with damping elements.
  • the upper part of the curtain is movable, the curtain scrolls at the upper part of the door, in a substantially stationary position, this position is placed below the mechanical actuating members of the curtain, and the edge lower cover is maintained near this substantially stationary position.
  • the lower edge of the cover can in this case be fitted with rollers or rollers mounted to rotate.
  • At least one wing of the crosspiece has an edge folded back 180 °, and the upper edge of the cover is also folded back 180 °, and the two edges are engaged one in the other, so that the lower edge of the cross member wing supports the hood.
  • a seal can be interposed between the fold of the cross member wing and the fold of the upper edge of the hood.
  • the lower edge of the hood may be provided with a seal, such as a rubber bead, a row of bristles or the like.
  • the lower edge can also be provided with damping elements.
  • the door comprises a rigid frame formed by two vertical lateral uprights 1, 2 joined at their upper parts by a cross member 3, in the form of an inverted U-beam, comprising a bottom 4 (or core) and two wings 5, 6 of which only one is visible in FIG. 1.
  • a curtain 7 is suspended by its upper edge from a bar 8 disposed below the cross-member 3.
  • the curtain 7 is of the folding type accordion to the upper part of the door. To do this, it is made of a flexible sheet material, reinforced by equidistant horizontal bars 9, the ends of which are guided in rails formed by, or formed in, the uprights 1 and 2.
  • the curtain can be raised by lifting straps 10, the lower ends of which are fixed to the lower bar, and which pass through loops fixed on at least some of the bars.
  • An example of such a curtain is disclosed in patent application EP-0 412 857 and US Pat. No. 5,072,767.
  • the straps can be wound on a winding shaft 11 placed in the cross-member. This can house other mechanical components such as a motor 12, a transmission block 13, a limit switch, electrical devices, etc. These elements can also be placed partially or completely in the uprights 1 and 2. Examples of such actuating members are described in patents EP-0 254 639 and US-4 828 003.
  • a cover 15 is placed between the lower edge 5A of the wing 5 of the cross member and the attachment line 8A of the curtain on the bar 8.
  • the upper edge 15A of the cover has a double folding 180 ° (twice 90 °) and the lower edge 5A of the wing 5 is folded likewise. (additional folding can be provided for aesthetic reasons).
  • a seal 16 can be placed between two folds, one of the cross member, the other of the cover, ensuring sealing and eliminating vibrations and noise.
  • the cover is suitably held at its ends, either on the bar 8, or on the uprights 1 and 2.
  • the lower edge 15B of the cover can be fitted with an appropriate seal to seal with the curtain while letting the straps.
  • the first is not technical, it is aesthetics. The mechanics are hidden, and the door has a cleaner appearance.
  • the cover can receive inscriptions: brands, conditions of use, etc.
  • the cover also serves as protection against falling objects. It is recalled that such doors can operate between 500 and 1000 times a day, sometimes more. Shocks and vibrations can cause ruptures, straps, their attachment, the winding shaft, etc. The fall of these parts is dangerous, and the cover protects precisely on the side where it is most important , because it is on this side that the staff can have the most to park near the door.
  • top rail is formed with folds on both sides, a cover can be placed on one side or the other, which allows the door to be turned over, or placed on the other side of the wall without turning it over , for example to take into account different local wind conditions or air pressures.
  • damping elements 17 to receive in particular the shock from the upper bar, under the edge of the cover which thus serves as a support for this damping element, or under the bar 8 for hanging the curtain.
  • the upper cross member 3 is identical to that of FIGS. 1 and 2, with a bottom, or core 4, and two wings 5, 6.
  • the cover 15 is mounted in the same way.
  • the curtain 20 reinforced by reinforcing bars 21 is picked up at the upper part by winding around a shaft 23.
  • the cover provides an aesthetic function, a sealing function, and a function of protection against falling objects, it allows easy access to the mechanics by removal, and allows the door to overturn. With this kind of curtain, the damping effect is not sought.
  • the lower edge of the cover makes it possible to pass the curtain to a stationary position, in correspondence with guide rails.
  • the lower edge of the cover 15 can be provided with rollers or rollers 22 suitably distributed.
  • the curtain can roll up the other way. The important thing is that it hangs vertically to the right of the bead from the lower edge of the cover, once it has come down to the rest position. One day is not bothersome, when the curtain is not lowered.
  • Figures 4 and 5 are similar views for a sectional door, with the curtain partially raised in Figure 4, and completely lowered in Figure 5.
  • the upper cross member 3 of the door is applied against a wall 30 above a bay 31.
  • slides 32 On the two sides are arranged slides 32 whose part corresponding to the bay is vertical, while above the slide is curved so as to return the curtain outside the plan of the bay.
  • the curtain 33 consists here of three panels 33A, 33B and 33C hinged to each other and on bars 34A-D whose ends slide in the slides 32. In the lowered position, the curtain closes the opening, the panels are all in the same plane ( Figure 5).
  • the cover 35 in this example has a slightly different shape. It is provided on its lower side with a sealing bead 36. As can be seen in FIG.
  • the sealing is achieved when a reinforcement and guide bar passes straight of the bead, while there is a day when it is the middle region of a panel which is at the level of the bead. But this is only a transient state, and this while the door is at least partially open.
  • the curtain is waterproof.
  • the cover plays its sealing and protective role. The removal of the cover allows access to the interior of the cross member, from the face of the door opposite the inclined extensions of the slides.
  • the curtain does not pass through a stationary horizontal line, but almost stationary to determine, the seal in any case in the closed position.
  • the present invention is also applicable to doors having a curtain with lateral displacement.
