Definitions

  • the present invention relates to a handling door for the passage of vehicles and machines comprising a flexible curtain resistant to the wind and having its opposite edges held in guides or slides.
  • the opening can be carried out by vertical lifting, either by winding around a tree, or by folding in accordion.
  • Second opening can be done by horizontal translation of the curtain consisting of one or two parts.
  • these types include a flexible curtain and one (possibly in the case of a horizontally translatable door) or two vertical or horizontal slides (depending on the type of opening).
  • the flexible curtain comprises one or more reinforcing bars intended to stiffen the curtain.
  • these bars or at least some of them, penetrate the slides in order to prevent the curtain from coming out of its plane when it is subjected to a thrust.
  • a vehicle accidentally hits the curtain. This can tear the curtain, or distort one or more bars which must then be replaced. There can ensue immobilization of the door.
  • the present invention more particularly relates to a door comprising a flexible curtain, in particular but not exclusively of large dimensions, the edges of which are guided in slides, the door being designed to withstand high pressures due to high winds, without get out of its slides, but having security in the event of a punctual impact against the door, for example the impact of a vehicle, to avoid tearing the door or deformation of the slides.
  • US Patent 2,839,135 discloses a roll-up door, consisting of rigid slats hinged to each other. At least some of the slats have at their ends a carriage which slides in slides without being able to leave it. This door is intended to withstand high winds. If the door receives a punctual shock, for example the shock of a truck, the slat which receives the shock will be bent or torn, or will deform the slide. In all cases, a repair is necessary, with a permanent immobilization of the door.
  • a punctual shock for example the shock of a truck
  • the present invention relates to a handling door with quick opening and closing for the passage of vehicles, comprising a flexible curtain, rollable or foldable, the edges of the curtain being each guided in a slide, and being retained there by retaining carriages guided by rails housed in the slides, without the carriages being able to leave said rails, the curtain comprising means for distributing the stresses constituted by at least one transverse resistance element, extending horizontally from one edge to the other, between two carriages, at least one of the two carriages being connected to the transverse resistance element by an articulation, characterized in that the articulation axis is a shearable dowel adapted to be break before the curtain is damaged by a determined force on the curtain.
  • the distribution means can be elements of transverse resistance constituted by stiffening bars of the curtain, retaining carriages being fixed at the two ends of at least certain bars, the bars being able to be connected to one another by flexible straps advantageously attached to the curtain.
  • the distribution means can also be constituted by flexible straps, fixed to the curtain transversely, retaining carriages being fixed at the two ends of at least certain straps.
  • the distribution means can also be constituted by flexible straps fixed to the curtain along its edges, the retaining carriages being fixed at intervals along such straps.
  • German patent DE-40 07 280 discloses a roll-up door in which the load bar is extended at its ends by sliding parts which penetrate into side rails.
  • the sliding parts are connected to the load bar by means of brittle parts adapted to break in the event of an impact against the load bar.
  • the brittle part For fixing the sliding part, on the load bar, the brittle part is extended by a connecting element which is bolted to the load bar.
  • a connecting element which is bolted to the load bar.
  • a pin as a connecting element has the advantage that its mechanical resistance can be determined with precision. As a result, the pins could be machined such that they resist strong winds and break under the effect of a punctual push of a certain force. In addition, it is possible to change the pin without using any specific tool. In addition to a gain in reliability is added a gain in downtime of the door.
  • EP-A-0 405 093 also describes a roll-up door with a load bar extended at its ends by sliding parts which penetrate into lateral slides. These sliding parts are connected to the load bar by separable links held by a pin. As in DE-40 07 280, the load bar does not support any longitudinal traction and the curtain itself is not protected.
  • the curtain rails prevent wind from entering directly through the guided sides of the door; moreover, it would be easy to adapt a sealing element on the slides on at least one side of the curtain, making it possible to effectively cut the wind.
  • these slides would constitute the uprights of the structure supporting the cross member in which the winding or folding mechanism is mounted.
  • FIGS. 1 and 2 relate to a handling door with a flexible curtain with vertical lifting, but the present invention is just as easily adaptable to a handling door which can be translated horizontally. This embodiment cannot therefore be limiting.
  • a flexible curtain lifting door with vertical lift has two vertical lateral uprights forming slides on which is generally mounted a crosspiece forming a lintel.
  • FIGS. 1 and 2 one of the two uprights of a door with vertical lift is shown which serves as a guide rail 1 for the flexible curtain stiffened by reinforcing bars 2 housed in the curtain 101 and whose ends penetrate into said slide 1.
  • This last slide 1 is constituted by a vertical U-shaped profile having two returns having the function of stiffening the structure of the upright.
  • the returns 1a also U-shaped, have two facing walls 11 which favor the guiding of the end of the rebar 2 in the slide 1.
  • a reinforcing plate 3 is welded, riveted or screwed in order to guarantee a solid base for a retaining rail 4 on which strong forces are exerted. tensions.
  • the retaining rail 4 is constituted by two symmetrical sections with respect to the cutting line II (see FIG. 1), and mounted on the reinforcement plate 3 so that it is easily removable for accessing the interior for example by means of screws and nuts 4b.
  • Said retaining rail 4 forming a slide has a longitudinal slot and two front walls 4a of each side of the slot on which rolls a carriage 5 provided with two rollers 5a mounted on an axis 5b.
  • the retaining rail 4 has two returns 41 facing each other and located on either side of the longitudinal slot. These returns 41 have the function of limiting the freedom of movement of the carriage 5 inside the retaining rail 4, but also of stiffening the structure of the retaining rail 4.
  • Element 7a of articulation 7 has a Y-shaped section along the line in section II in which the element 7b of the articulation 7 is inserted.
  • the two elements 7a, 7b have coaxial or aligned bores in which is inserted a pin 71 constituting the axis of the articulation 7.
  • the pin 71 is adapted to break when a predetermined force is applied to the reinforcing bar 32 perpendicular to the curtain so that said reinforcing bar 2 is detached from its carriage 5.
  • the pin 71 is machined so as to withstand strong winds because the force is distributed over the entire curtain and so as to break under the effect of a punctual push of a certain force which is only exerted on a single bar or at most two.
  • the pin 71 is provided with a pin 71a in order to avoid any accidental withdrawal of the pin 71.
  • the advantage of a removable brittle pin as a connecting element is on two levels. First, it is easier to determine the breaking point (i.e. the mechanical strength). Secondly, the replacement of the pin does not require the intervention of a specialized technician, therefore the downtime of the door is reduced.
  • the rebar 2 is of hollow construction and has sufficient overall flexibility to allow it to exit from at least one slide 1 under the effect of a collision in the flexible curtain.
  • Said reinforcing bar 2 is here a tube and receives at each of its ends a rod 8 secured to the element 7a of the articulation 7.
  • Figure 1 is shown in section an example of a device for adjusting the sinking of the rod 8 inside the bar, that is to say a means for adjusting the length of the bar and adjusting its tension. in the presence of wind.
  • the rod 8 is provided at its free end, opposite the articulation 7, with a head 8a of larger diameter, thus having a shoulder 8b by which this head can be retained.
  • a sleeve 9 is housed in the end of the bar 2, and can be held there by pins 9a indicated diagrammatically.
  • the diameter of the head 8a is provided to slide freely inside the sleeve 9.
  • the interior surface of the sleeve 9 is threaded and a sleeve 10, externally threaded can be screwed into the sleeve.
  • the internal diameter of the sleeve 10 allows the rod 8 to be freely received, but not the head 8a, the step 8b of which is applied against the end edge of the sleeve.
  • a lock nut 10a makes it possible to block the bushing in the chosen position, that is to say allows the distance between the end of the bar 2 and the axis of the articulation 7 to be chosen.
  • FIG. 3 Another embodiment of the invention is shown in Figures 3 and 4 relating to a rolling curtain.
  • the flexible curtain 101 is provided at different heights, to ensure transverse resistance between the sides, with a polyester strap 102.
  • This strap is placed inside a sheath made up of two plastic sheets 103a, 103b a little more as wide as the strap and welded at their edges, the assembly being welded or glued to the flexible curtain 101.
  • a metallic connecting piece is constituted in this example by two blades or rigid plates 104a, 104b, for example made of steel, arranged on both sides of the strap and tightened against the latter by screws and nuts 105a, 105b.
  • the blades are cut with an opening 106 provided for the passage of the axis 107 of the rollers 108.
  • Another example of slide 109 is shown in section in FIG. 3.
  • the arrangement which has just been described makes it possible to regularly wind the curtain which is thus completely flexible, and the steel blades can be placed on the edge of the winding shaft of the curtain, and ensure, during the unwinding, the correct placement of the rollers in the slides.
  • the gaps between the different straps distributed over the height of the curtain may not be equal, if necessary, to prevent the rollers from overlapping, hampering the winding.
  • the force exerted by the wind on the curtain is taken up over the entire width by the straps 102, and is thus transmitted to the slides by the rollers.
  • interpose safety means between the retaining rollers and the stress distribution means to separate the rollers from said distribution means, in the event of excessive or abnormal force, for example concentrated on a single strap, for example by the impact of a vehicle.
  • these means can be achieved by the use of screws which can be sheared at a certain shearing force, for example made of plastic, for the clamping screws 105 which hold the steel blades 104 together. This means is simple and in the event of a breakage, the screws can be replaced immediately without the intervention of any specialist.
