Definitions

  • the invention relates to film doors.
  • any film that unwound from a winding roll in the unwound state closes an opening, regardless of whether the unwinding direction is vertical or horizontal, whether the unwound film is vertical, oblique or horizontal and thus whether an opening locked in a building or on a mobile object.
  • the door In the case of film doors, the door consists of a winding roll, usually transversely above the door opening, as well as a film that can be wound thereon so that when the film is unwound from the winding roll, the door film, which is usually guided in lateral, vertical guides, closes the door opening.
  • the lateral edges In order to achieve the required lateral tightness, the lateral edges must be guided in lateral guides.
  • the door foil for opening and closing is vertically moved in the door opening, and therefore, the opening and closing direction of the door foil is identical to the vertical direction.
  • the opening and closing direction of the goal foil is equated with the vertical direction, without limiting the invention thereto.
  • edge thickening two flat, parallel to the main plane of the door surface extending outer surfaces having sufficient width when winding the Torfolie this edge thickening can easily be wrapped several times over each other, like the Torfolie itself, without the risk, as in a narrow, thickened piping that this is irregularly deposited in the axial direction next to each other and thereby leads to drapery or even jamming of the Torfolie on the winding roll, which can very easily lead to jamming in the vertical guides especially at later closing of the door.
  • a width of the edge thickening in the transverse direction of 2, 3 or even 5 cm makes sense, it has been found that a thickness of the edge thickening of at least 2, better 3 or 4 mm is necessary, so that in the transverse direction of the Torfolie facing shoulder surface of this edge thickening , which in particular is a flat shoulder surface, is sufficiently wide for good guidance and support.
  • the edge thickening is realized as an edge strip which is welded, glued or latched onto the edge of the film and which extends in the closing direction and consists of individual thickening plates.
  • the thickness of the Torfolfolie should have the thickness of the edge thickening a multiple, at least five times, better seven times the thickness of the Torfolie.
  • edge thickening is not to be performed by means of rollers but by sliding guides on the edges, should be used as a material for the edge thickening, at least on the outer surfaces, a low-friction material such as Teflon.
  • the preparation of the edge thickening or its outer layer of low elastic, in particular rigid plates z. B. offer Teflon, which are then applied to each other in the closing direction with or without clearance on the Torfolie and adapted to the diameter of the winding roll in the closing direction only have such a length that then still a trouble winding on the winding roll is possible.
  • the individual thickening plates of the edge thickening which adjoin one another in the closing direction, can either line up as closely as possible, in particular without gap, or deliberately at a distance to allow this distance for other purposes, such as the engagement of a pinion.
  • FIG. 1a shows the basic situation of a Folientores 1 in the front view in the closed state:
  • the lowered goal foil 2 is located in front of the door opening 3 to be closed and is fastened with its upper edge to a winding roll 4 arranged horizontally transversely at the upper end of the door opening 3.
  • the winding roller 4 is driven in rotation by a drive motor 7 in the winding, whereby the Torfolie 2 is wound on the winding roller 4 and the door opening 3 releases.
  • the lateral edges 2a, b of the goal foil 2 are each guided in vertical guides 6a, b, and the lower edge 2c of the goal foil 2 is frequently weighted in order to be unwound the Torfolie 2 at the beginning to have a sufficient draw weight down, for example, by a sewn into the lower edge 2c bag 13, in which a heavy bulk material 14, such as sand, is located.
  • FIGS. 1b and 2 show in an enlarged view the guidance of a lateral edge 2b in the guide 6b, as in practice, however, at both edges 2a, b is present.
  • an edge thickening 5 applied, in the form of thickening plates 15a, b, which are arranged in the closing direction 10 behind each other on at least one, preferably on both sides of the Torfolie 2.
  • the thickening plates 15a, b are formed in the transverse direction 50 of the gate longer than in the closing direction 10, wherein they have at the outer edge of the Torfolie 2 with these ends and on their the middle 30 facing the end face a shoulder surface 5a, which for supporting on the lateral guides 6a, b serve.
  • the extension in the transverse direction 50 serves, above all, to be able to connect these thickening plates 15a, b firmly and permanently to the goal foil 2.
  • a positive mechanical connection is preferred here, as in the FIGS. 4 shown:
  • the thickening plates 15a In their course direction, ie in the transverse direction 50, the thickening plates 15a have one or preferably a plurality of latching pins 22, which consist of a longitudinal direction slotted socket and have a thickened free end. Further, in the thickening plate 15a detent holes 24 are formed as through holes, which are suitable for receiving locking pin 22 of a directed against it thickening plate 15b and accordingly have an undercut for the positive recording of its end-side thickening.
  • the thickening plates 15a, b otherwise the same size in terms of their dimensions. Between two mutually latched to one another thickening plates 15a, b is inserted before the nesting of the edge 2a or 2b of a Torfolie 2, which is perforated for this purpose at the positions of the locking pin 22 so that they pushed through the Torfolie into the other thickening in it can be.
  • the thickening plates are dimensioned and arranged in such a way that, depending on the diameter of the winding roll 4, they do not hinder the winding up of the goal foil 2 on the winding roll 4:
  • the thickening plates 15a, b are formed substantially preferably rigid, so that when winding on the winding roll 4 to adapt to the circumference of this winding roll 4 only the Torfolie 2 is bent in its edge region 2a, b, but not the thickening plates attached thereto 15a, b ,
  • the thickening plates 15a on the one side and 15b on the other side which must always be arranged at least when nesting in the same longitudinal positions, a distance, inter alia, of the thickness of the thickening plates and of the diameter of the winding roll 4th depends.
  • the thickening plates 15a, b have on their longitudinal side lying on the goal foil 2 a bevelled edge in their course direction, as in FIG Fig. 3c shown in the left half of the picture, so that their contact surface applied to the Torfolie 2 is narrower than its opposite outer surface.
  • the thickening plates 15a, b can be arranged even without spacing in the closing direction 10, then they will preferably have a chamfer on the outside along their edges running in the direction of the thickening plates, as in FIG Fig. 3c , right side shown.
  • This bevel preferably proceeds as far as the contact surface, ie the underside, of the thickening plates relative to the door foil 2, so that the thickening plates 15a, b then have a trapezoidal cross section and their contact surface is wider than their outer side.
  • Fig. 2 shows in a sectional view how the Torfolie 2 is guided with its edge region and the thickening plates 15a, b mounted thereon in a guide profile 37, which serves as a vertical guide 6a or 6b:
  • the guide profile 37 is designed in principle C-shaped, however, in the course of its free-ending legs, a first constriction 35, from which extends to the closed end, a cavity 34, and a second constriction 36, through the free ends of this C -Profiles is formed so that between the first constriction 35 and the second constriction 36 in turn a cavity 31 in the guide profile 37 is present.
  • the Torfolie 2 which ends with its lateral edge in the first cavity 34, extends through the gate center 30th
  • the second constriction 36 is additionally reduced by an applied on both sides of the Torfolie 2 in this area gap seal 28 which is formed on a sealing profile 29 which is pushed in the closing direction 10 of the Torfolie form-fitting manner on the correspondingly shaped free ends of the freely extending legs of the guide profile 37 can be or otherwise attached to it.
  • the legs of the guide profile 37 continue to have seen in cross-section closed cavities, which serve to further stabilize the guide profile and its attachment to the film door 1 surrounding building.
  • the edge region 2 a or 2 b of the door foil 2, on which the thickening plates 15 a, b are applied, is located in the first cavity of the guide profile 37, which has an oval or lens-shaped cross section.
  • the thickening plates 15a, b lie with their shoulder surfaces 5a, b on an opposing guide surface 37a of the guide profile 37 and slide along it during opening and closing of the film gate 1.
  • the guide profile 37 which is usually made of metal, for example aluminum, and is an extruded profile, arranged a lubricious coating of plastic, here in the form of a Gleitprofiles 38, which covers both the guide surface 37 a, the thickening plates 15 a, b facing as well as the actual constriction 35 in the transverse direction 50 of the gate.
  • the thickening plates 15a, b are preferably not with their remaining circumference at the peripheral walls of the cavity 34, since with sufficient contact pressure of the shoulder surfaces 5a to the guide surfaces 37a and the edge region 2b is held on the main plane 40 of the door.
  • Guide surfaces 37a, b may be arranged on the guide profile 37, which lie on the parallel to the main plane 40 of the door outer surfaces 5b of the thickening plates 15a, b and slide and then preferably also from a lubricious coating, possibly in turn a sliding profile, covered.
  • each one of the guide plates 15'b may be formed shorter in its direction than the opposite thickening plate 15'a.
  • both thickening plates 15'a, b terminate in alignment with one another with the laterally outer end of the goal foil 2.
  • one of the previously described detent holes 24 is formed in the projection of the longer thickening plate 15'a. It is inserted from the opposite side of the Torfolie 2 forth instead of a conventional locking pin 22, a guide roller 26 which is rotatably mounted in a locking pin 22 as a foot.
  • the guide roller 26 has a diameter 27 which is dimensioned relative to the detent hole 24 so as to project slightly beyond the end of the opposed longer thickening plate 15'a and in operation according to FIG Fig. 2 on the guide surface 37a of the guide profile 37 rests. Notwithstanding the solution according to Fig. 4d for example, the shorter thickening plate 15'b can also extend below the guide roller 26 and have a through-hole for it, which can reduce the sliding friction of the roller 26 on its rear side.
  • the diameter 27 should not be greater than the width of the thickening plates 15'a, 15'b and - if these are used in alternation with no rollers 26, normal thickening plates 15a, b, not greater than the width thereof.
  • the thickening plates 15a, b are arranged in the closing direction 10, preferably over the entire length of the goal foil 2, and / or the guide profiles 37 are arranged along the entire height of the door opening 3, preferably on both sides as lateral vertical guides 6a, b.
  • the guide profile 37 is attached to the surrounding building, so the door opening 3, usually by screwing.
  • edge thickening 5 so the thickening plates 15a, b, applied detachably on an edge strip 16 of the goal foil 2 and this by means of Velcro 42 at the rest of the goal foil.
  • an additional drive may be provided in addition to or instead of the drive of the winding roller 4 in the closing direction 10, such as based on the Figures 5 and 6 shown.
  • FIG. 5 shows a solution in which the lower end, so the lower edge 2c of the Torfolie 2, is pulled down during closing by at least from the lower edge 2c - preferably near the outer edges 2a, b - a drawstring 8 as a tension element on the Torfol 2 is attached, which - as in FIG. 5b and 5c represented - over lower pulleys 23a, b deflected at the lower end of the door opening upwards and wound there.
  • the drawstring 8 can optionally be done directly on the winding shaft 4, for example on a relative to the winding circumference for the Torfolie 2 changed diameter 4 ', or on a separate winding roll 4', as in Fig. 5c shown.
  • winding roll 4 ' is also driven for the tension element, z. B. from the winding roll 4 or the drive from, at different diameters compensation either by a correspondingly elastic tension band 8 or by a freewheel z. B. can be achieved in the winding roll 4.
  • a pull rope is used as a tension element and used as a winding roller 4 ', a tapered winding roll on the conical surface a single spiral groove 39 is incorporated for receiving the traction cable, the diameter thus increases in the axial direction.
  • the free end of the traction cable is attached to the end of the spiral groove with the largest diameter and the cone angle and thus the diameter increase of the spiral groove 39 is dimensioned so that it corresponds to the change in diameter of the film roll on the winding roll 4.
  • the spiral groove 39 is so deeply incorporated into the conical surface of the conical winding roll 4 ', that a jump over the pull rope from one track to the next of the spiral groove 39 is not possible.
  • FIG. 5c also shows sewn into the Torfolie 2, transversely extending pockets 13 into which can be filled for weighting at the lower edge of bulk material 14 or for stabilization against wind pressure stabilization tubes 22 can be used.
  • FIG. 6 shows a solution in which the Torfolie 2 in the central region, ie in particular on the gate center 30, by an additional central guide 6 'is stabilized.
  • the vertical central guide 6 ' is not a vertically fixed guide, since it must release the door opening 3 in the open state.
  • this is an at least about a central hinge upwards, in the horizontal, collapsible linkage, which is movable by a drive motor 7 'in the closed position of the door, and in which at least the lowest point with the lower edge 2c remains firmly connected , while over the rest of the height, the vertical guide 6a ', 6b' is only closed by the vertical guide 6 'has reached its vertically unfolded end position.
  • This chain 48 one of which is present close to each edge 2a, b and in particular close to each vertical guide 6a, b, is provided with one end, e.g. B. attached to the upper end of the guide profile 37 of the vertical guide 6a, b, placed around the outside of the roll of Torfolie 2 and hangs with its free end, which is weighted by the weight 16, next to the guide profile 37 down.
  • the chain 48 is located on the outer peripheral surface of the coil, so the Torfolie 48 on.
  • FIG. 7b shows the state with fully closed gate and unwound goal foil 2.
