Definitions

  • the present invention relates to a watertight lifting curtain handling door.
  • These doors used in industrial or commercial premises, factories, warehouses, garages, stores, etc., have a movable curtain that can be raised or lowered to free or close a bay in a wall.
  • a door comprises a frame consisting of two lateral uprights, each forming or comprising a slide for the edge of the curtain, and most often an upper horizontal crosspiece joining the upper parts of the uprights.
  • the present invention relates more particularly to a device ensuring the seal between the edge of the curtain and the corresponding slide, allowing a silent movement, promoting sliding and providing good wind resistance.
  • the curtain can be constituted by a flexible tarpaulin, made of fabric or plastic, reinforced or not by reinforcing bars, the curtain being able to be folded or rolled up at the upper part of the door.
  • the curtain can also consist of rigid panels hinged to each other. It will be understood that in the latter case, the device of the invention could be applied to the case where the displacement of the panels is not vertical.
  • An object of the invention is to obtain a good seal of the door in the closed position. Another object of the invention is to obtain silent operation and good sliding of the edges of the curtain in the slides.
  • the invention relates to a lifting curtain door, comprising two rigid lateral uprights disposed on both sides of the opening of a bay, each forming or comprising a slide, and a curtain disposed between the uprights , the vertical edges of the curtain each sliding in a slide, characterized in that each slide has a vertical slot formed in the rigid wall of the upright disposed towards the center of the curtain, delimited by two edges, and a flexible sealing sheet joining on essentially the entire height of the slot, the two edges, so as to delimit a vertical pocket on the side opposite to the center of the curtain intended to receive an edge of the curtain, this edge being in flexible abutment against the bottom of the pocket, which bottom has '' sufficient play to absorb movement and deformation of the edge of the curtain.
  • the flexible sealing sheet is provided on its two edges with straight rods, and the rods are fixed to the edges of the slide.
  • the tarpaulin can be a flattened tube, and the rods are passed inside.
  • the edges of the slide can be lined with a plastic profile favoring the sliding of the edge of the curtain.
  • the profile is fixed by elastic snap-fastening on the edge of the slide.
  • the profile comprises a longitudinal housing for receiving said rod.
  • FIG. 1 shows an example of a lifting curtain door to which the invention can be applied (not visible in this drawing).
  • This door consists of two lateral uprights 1, 2 joined at their upper parts by a cross member 3.
  • a flexible curtain 4 can close or release a bay 5 formed in a wall 6, by lowering or lifting.
  • the edges 4a of the curtain 4 slide in slides 7 formed in the lateral uprights.
  • the curtain can be reinforced by reinforcing bars 8, and in this case, the ends of the bars can extend to the inside of the slides.
  • the invention also applies to the case where there is no bar, or even to the case where the ends of the bars do not penetrate the slides.
  • the flexible curtain 4 can be wrapped around a tree located for example in the cross member 3, or can fold in an accordion at the top of the door.
  • the invention also applies to doors comprising a curtain made up of rigid panels juxtaposed or articulated to each other, and the lateral edges of which slide in the slides.
  • the rigid upright 2 which can be of metal or other material, wood or plastic. It has an opening 7 forming part of the slide, formed in the wall 9 of the upright 2, which looks at the center of the door and separating this wall into two parts 9a, 9b.
  • the edges of the wall 9 can be folded back to form the edges 7a, 7b of the slide, as shown.
  • the upright can be in one piece, but it is often advantageous that a side 2a can be dismantled to facilitate manufacture and maintenance.
  • On the edges 7a and 7b of the slide are fixed the edges 11b and 11c of a tarp in the form of a strip 11 of a resistant plasticized fabric to form a vertical pocket 12.
  • the edge 4a of the curtain 4 is engaged in this pocket, so as to be, when the door is in the closed position, in elastic abutment against the bottom 11a of the pocket. This produces sealing of the edge of the curtain when the door is closed, and a flexible and silent operation in motion.
  • the tarp also provides thermal insulation and limits the effects of frost.
  • the bottom 11a of the pocket can freely debate in the opposite direction of the opening 7 of the slide, and is therefore at a sufficient distance from the opposite wall 2b of the upright 2 (or that there is no stud wall in this direction).
  • the edges of the flexible sheet 11 can be fixed to the edges 7a, 7b of the slot 7 by any suitable means. An advantageous practical example will now be described with reference to FIG. 3.
  • FIG. 3 The section of FIG. 3 was made at the level of a reinforcing bar of the curtain, in the case where the latter has it. Only the folded edges 7a, 7b are shown on the figure on either side of the slot 7, the edges 9a, 9b of the wall 9 of the upright 2.
  • sliding profiles 26 of plastic are engaged by deformation and locked on the edges 7a, 7b of the slide.
  • These profiles have a rounded face 26a in the slot of the slide. very favorable to sliding and eliminating the risk of snagging.
  • these profiles are used to simply fix the waterproof cover.
  • the profile has a (longitudinal) housing 28 with an access passage 29 throttled, while the edges of the sheet are provided with a straight rod 25 (wood or plastic) with a diameter greater than the width of the passage throttled, but allowing however to introduce it into the housing 28 by elastic deformation of at least one wall of said profile.
  • the section of Figure 3 shows a simple way to attach the rods 25 to the tarpaulin.
  • the latter simply consists of a flat tube, and the 2 rods are simply engaged in it.
  • the cut was made by a horizontal plane passing through the axis of a reinforcing bar.
  • the bar comprises a flexible tube 21, for example made of metal or reinforced plastic, of a length little less than the distance between the slides.
  • a nozzle 22 (see Figure 4) is engaged in the flexible tube to extend the latter by a thinned portion 22, extending in a vertical plane.
  • This thinned part 22a is intended to move in the slide, and has a reduced thickness, fairly comparable to that of the curtain.
  • the tube can have a diameter of 3cm, and the thinned part 1 / 2cm.
  • the tip may have at the other end 22b a portion of reduced section with a shoulder 22c to obtain a defined and precise connection.
  • connection can be obtained by force fitting, by gluing, etc.
  • the end piece can be made of plastic rigid enough to hold the curtain in position in the slides under the effect of the wind, but nevertheless flexible enough to fold and disengage from the slide, under the effect of an abnormal force, for example the percussion of a vehicle in the curtain.
  • the curtain can be trimmed on both sides, at the level of the reinforcing bar, by strips of plastic or plasticized fabric 23a, 23b (see also Figure 5) which are extended up to the end of the end piece, so as to completely wrap it by folding it over one another at 23c. These strips are welded together above and below the bar, thus forming a sheath.
  • the part of the end piece located in the groove of the slide, between the rounded faces 26a can be fitted on both sides, therefore facing the two rounded faces 26a, by sliding shoes 24, advantageously provided with ribs 24a arranged vertically. These pads reduce wear, facilitate sliding and oppose the axial movement of the bar.
