Description

La présente invention concerne les portes dites de manutention à rideau relevable ou effaçable latéralement. Ce sont les portes disposées dans les usines, entrepôts, magasins, garages, etc. qui servent à isoler du bruit ou du froid, de l'extérieur ou entre locaux adjacents. Ces portes comportent généralement un cadre, constitué dans les portes relevables de deux montants latéraux, réunis à leurs parties supérieures par une traverse horizontale et un rideau généralement en matière plastique, qui peut être relevé rapidement pour laisser le passage et qui est amassé en haut de la porte, au-dessus du passage dégagé, par pliage en accordéon ou par enroulement. L'invention concerne particulièrement les portes au moins en partie transparente. En effet, le passage d'un véhicule, camion, chariot de manutention, etc., doit se faire rapidement. Le rideau se dégage latéralement ou se relève verticalement automatiquement à l'approche du véhicule qui ralentit à peine, et il est important que le conducteur du véhicule puisse voir si l'espace est dégagé de l'autre côté de la porte ou si un autre véhicule arrive en sens inverse.The present invention relates to so-called handling doors with a lifting or laterally erasable curtain. These are the doors arranged in factories, warehouses, stores, garages, etc. used to isolate noise or cold, from the outside or between adjacent rooms. These doors generally comprise a frame, constituted in the liftable doors of two lateral uprights, joined to their upper parts by a horizontal crosspiece and a curtain generally made of plastic, which can be raised quickly to leave the passage and which is gathered at the top of the door, above the clear passage, by folding in accordion or by winding. The invention particularly relates to doors at least partially transparent. Indeed, the passage of a vehicle, truck, handling cart, etc., must be done quickly. The curtain clears sideways or flips up vertically automatically when approaching the vehicle which is barely slowing down, and it is important that the driver of the vehicle can see if the space is cleared on the other side of the door or if another vehicle arrives in reverse.

Lorsque le rideau en partie transparente est amassé à la partie supérieure ou sur le côté de la porte, les différentes parties du rideau peuvent frotter les unes contre les autres : la surface du rideau, généralement en plastique devient rapidement dépolie et la visibililité en est d'autant réduite.When the partially transparent curtain is collected at the top or on the side of the door, the different parts of the curtain can rub against each other: the surface of the curtain, usually made of plastic, quickly becomes frosted and visibility is d 'reduced as much.

Souvent les rideaux sont armaturés par des barres horizontales de raidissement, assurant le guidage du rideau dans des glissières latérales. Lors de l'enroulement du rideau, ces barres viennent frotter contre les parties transparentes du rideau, ce qui accentue l'effet de dépolissage. En outre, lors de l'enroulement et du déroulement du rideau, ces barres, en arrivant sur le paquet de rideau en cours d'enroulement, ou en le quittant provoque un bruit important qui gêne l'environnement.Often the curtains are reinforced by horizontal stiffening bars, ensuring the guiding of the curtain in side rails. When the curtain is rolled up, these bars rub against the transparent parts of the curtain, which accentuates the frosting effect. In addition, during the winding and unwinding of the curtain, these bars, arriving on the curtain package during winding, or leaving it causes a significant noise which disturbs the environment.

Conformément à la présente invention, une porte de manutention à rideau effaçable notamment relevable, comportant un rideau souple enroulable ou repliable au moyen d'au moins un arbre rotatif d'enroulement, est caractérisée en ce que ledit rideau est garni, au moins sur une face, d'au moins une bande souple disposée perpendiculairement à l'arbre et formant une surépaisseur, ou bande d'écartement, de façon que lors de l'enroulement ou du pliage du rideau, cette bande s'enroule ou se plie sur elle-même, de façon à maintenir les plis ou les tours du rideau écartés les uns des autres dans la position dégagée ou relevée.According to the present invention, a handling door with an erasable curtain, in particular a lifting curtain, comprising a flexible curtain that can be rolled up or folded by means of at least one rotating winding shaft, is characterized in that said curtain is fitted, at least on one face, of at least one flexible strip arranged perpendicular to the shaft and forming an additional thickness, or spacer strip, so that when the curtain is rolled up or folded, this strip is rolled up or folded over it -same, so as to keep the folds or the turns of the curtain separated from each other in the released or raised position.

Pour la clarté de l'exposition, on a choisi un mode de réalisation de l'invention dans lequel le rideau est relevable ce qui est un cas fréquent jusqu'à aujourd'hui. Il est évident que l'invention couvre le cas où le rideau se dégage suivant une autre direction que la verticale, l'important étant que la bande d'écartement soit orientée dans la direction du dégagement, de façon à s'enrouler ou se replier sur elle-même pour écarter les plis du rideau les unes des autres et ainsi réduire les frottements et le bruit entre les plis.For the clarity of the exhibition, an embodiment of the invention has been chosen in which the curtain is liftable, which is a frequent case until today. It is obvious that the invention covers the case where the curtain emerges in a direction other than the vertical, the important thing being that the spacer strip is oriented in the direction of the release, so as to roll up or fold back on itself to separate the folds of the curtain from each other and thus reduce friction and noise between the folds.

Selon une autre caractéristique de l'invention, il est prévu également des bandes d'écartement dans au moins une autre direction, notamment perpendiculairement à la première, c'est-à-dire parallèle à l'axe d'enroulement.According to another characteristic of the invention, spacers are also provided in at least one other direction, in particular perpendicular to the first, that is to say parallel to the winding axis.

Avantageusement, une bande d'écartement parallèle à l'axe d'enroulement contient ou forme un élément de rigidification du rideau, notamment une barre d'armature.Advantageously, a spacer strip parallel to the winding axis contains or forms a stiffening element of the curtain, in particular a reinforcing bar.

Selon une caractéristique avantageuse de l'invention, des bandes d'écartement peuvent être placées sur les bords du rideau. Dans une forme de réalisation de l'invention, de telles bandes d'écartement placées sur les bords du rideau peuvent servir de bourrelets de guidage des bords du rideau dans des glissières appropriées.According to an advantageous characteristic of the invention, spacer strips can be placed on the edges of the curtain. In one embodiment of the invention, such spacing strips placed on the edges of the curtain can serve as guide beads for the edges of the curtain in suitable slides.

D'autres caractéristiques et avantages de l'invention apparaîtront au cours de la description ci-après, donnée à titre d'exemple non limitatif, en regard des dessins ci-joints, et qui fera bien comprendre comment l'invention peut être réalisée.Other characteristics and advantages of the invention will appear during the description below, given by way of nonlimiting example, with reference to the attached drawings, and which will make it clear how the invention can be implemented.

Sur les dessins,

  • la figure 1 est une vue de face d'un exemple schématique de rideau selon l'invention, partiellement enroulé,
  • la figure 2 est une vue en coupe de la partie enroulée du rideau, par un plan passant par l'axe d'enroulement,
  • la figure 3 est une vue de face d'une porte de manutention selon l'invention, équipée d'un rideau selon une autre forme de réalisation, et
  • les figures 4, 5, 6 et 7 sont des vues en coupe du rideau de la figure 3 respectivement par les plans IV-IV, V-V, VI-VI et VII-VII.
In the drawings,
  • FIG. 1 is a front view of a schematic example of a curtain according to the invention, partially wound,
  • FIG. 2 is a sectional view of the rolled-up part of the curtain, through a plane passing through the winding axis,
  • FIG. 3 is a front view of a handling door according to the invention, equipped with a curtain according to another embodiment, and
  • Figures 4, 5, 6 and 7 are sectional views of the curtain of Figure 3 respectively by the plans IV-IV, VV, VI-VI and VII-VII.

Un exemple de porte à laquelle peut s'appliquer l'invention est représenté sur la figure 3. Cette porte comporte deux montants latéraux 1, 2 formant glissières pour les bords du rideau, et une traverse supérieure 3 joignant les extrémités supérieures des montants. Ces montants et la traverse sont placés autour d'une baie qui peut être obturée ou dégagée au moyen d'un rideau 4, qui peut s'enrouler sur un arbre d'enroulement logé dans la traverse. (L'arbre est schématisé par l'axe 5 sur les figures 1 et 2. ) Au lieu de s'enrouler, le rideau pourrait se replier en accordéon. Dans ce cas, il est remonté par des sangles qui sont accrochées au bas du rideau et s'enroulement sur l'arbre d'enroulement. On verra que l'invention s'y applique de la même façon avec le même résultat.An example of a door to which the invention can be applied is shown in FIG. 3. This door has two lateral uprights 1, 2 forming slides for the edges of the curtain, and an upper cross member 3 joining the upper ends of the uprights. These uprights and the crosspiece are placed around a bay which can be closed or released by means of a curtain 4, which can be wound on a winding shaft housed in the crosspiece. (The tree is shown schematically by the axis 5 in Figures 1 and 2.) Instead of being rolled up, the curtain could be folded down in accordion. In this case, it is reassembled by straps which are hung at the bottom of the curtain and wind on the winding shaft. It will be seen that the invention applies to it in the same way with the same result.

Deux exemples de rideaux sont représentés sur les figures 1 et 3.Two examples of curtains are shown in Figures 1 and 3.

Le rideau de la figure 1 est constitué d'une nappe transparente 6 qui peut s'enrouler autour d'un arbre 5 pour dégager la baie, ou se dérouler pour l'obturer. Selon l'invention, deux bandes 7, 8 présentant une certaine épaisseur (voir figure 2) sont formées sur le rideau, de façon à s'enrouler sur elles-mêmes lors du relèvement du rideau. La surépaisseur peut être formée d'un seul côté, ou des deux, comme représenté sur la figure 2. Dans ces conditions, quand le rideau est enroulé, les faces du rideau ne sont pas en contact recto contre verso, on n'y sont que ponctuellement et sans pression en tous cas au voisinage des bandes. Il en résulte que les surfaces ne sont pas dégradées et que la nappe du rideau garde une bonne transparence dans le temps.The curtain of Figure 1 consists of a transparent sheet 6 which can be wound around a tree 5 to clear the bay, or unwind to close it. According to the invention, two strips 7, 8 having a certain thickness (see FIG. 2) are formed on the curtain, so as to roll up on themselves when the curtain is raised. The extra thickness can be formed on one side, or both, as shown in FIG. 2. Under these conditions, when the curtain is rolled up, the curtain faces are not in front-to-back contact, we are not there only punctually and without pressure in any case in the vicinity of the strips. The result is that the surfaces are not degraded and that the curtain ply retains good transparency over time.

La surépaisseur doit être notable. Par exemple pour un rideau d'une épaisseur de quelques millimètres (2 à 5), la surépaisseur pourra être de un à trois centimètres. La surépaisseur dépend aussi du nombre des bandes. On comprend que s'il y en a davantage, la surépaisseur pourra être moindre.The extra thickness must be significant. For example, for a curtain a few millimeters thick (2 to 5), the additional thickness may be one to three centimeters. The extra thickness also depends on the number of bands. We understand that if there are more, the extra thickness may be less.

On obtient aussi une amélioration en plaçant des bandes d'écartement horizontales. On pourra aussi constituer des bandes d'écartement horizontales par des éléments de raidissement du rideau.An improvement is also obtained by placing horizontal spacing strips. It is also possible to form horizontal spacing strips by stiffening elements of the curtain.

Sur la figure 3, le rideau est renforcé, et guidé, par des barres d'armature 9 dont les extrémités sont engagées dans des glissières formées dans les montants 1 et 2. Le rideau est constitué par des lés 11, 12 (figure 5) qui se chevauchent en formant un fourreau entourant la barre 9. Ces lés 11, 12 sont transparents. Dans un but d'esthétique et de renforcement, des bandes opaques 13, 14 sont appliquées des deux côtés du fourreau.In FIG. 3, the curtain is reinforced and guided by rebar 9, the ends of which are engaged in slides formed in the uprights 1 and 2. The curtain is formed by strips 11, 12 (FIG. 5) which overlap by forming a sheath surrounding the bar 9. These strips 11, 12 are transparent. For aesthetic and strengthening purposes, opaque strips 13, 14 are applied on both sides of the sheath.

Des éléments de bande d'écartement (de surépaisseur) sont disposés verticalement (perpendiculairement à l'axe d'enroulement). Dans l'exemple représenté, la surépaisseur est formée par une bande 15 en mousse synthétique, recouverte et maintenue en position par une feuille plastique souple 16 de protection soudée (ou collée, ou rivée, etc.) le long du pourtour de la bande en mousse.Spacer tape elements (extra thickness) are arranged vertically (perpendicular to the winding axis). In the example shown, the additional thickness is formed by a strip 15 of synthetic foam, covered and held in position by a flexible plastic sheet 16 of protection welded (or glued, or riveted, etc.) along the periphery of the strip in foam.

Du fait de la présence des fourreaux des barres de renforcement, les bandes d'écartement sont formées par des segments s'étendant d'une barre à l'autre (voir figure 6). La feuille plastique de protection est soudée aux extrémités, dans cet exemple, sur les bandes opaques 13, 14 qui garnissent les fourreaux des barres de renforcement.Due to the presence of the sheaths of the reinforcing bars, the spacer strips are formed by segments extending from one bar to the other (see FIG. 6). The protective plastic sheet is welded at the ends, in this example, to the opaque strips 13, 14 which line the sleeves of the reinforcing bars.

Dans la réalisation de la figure 3, les bandes d'écartement protègent la surface du rideau, et uniformisent le diamètre d'enroulement, ce qui réduit les irrégularités dues à la présence des barres, dans les cas où elles sont présentes. On réduit ainsi les bruits d'enroulement et de déroulement du rideau. On obtient une port dont la transparence est persistante, et dont le fonctionnement est particulièrement peu bruyant. Dans ce but, on comprendra que l'invention peut aussi s'appliquer à des portes non transparentes.In the embodiment of FIG. 3, the spacer strips protect the surface of the curtain, and standardize the winding diameter, which reduces the irregularities due to the presence of the bars, in the cases where they are present. This reduces the winding and unwinding noise of the curtain. We obtain a port whose transparency is persistent, and whose operation is particularly quiet. For this purpose, it will be understood that the invention can also be applied to non-transparent doors.

Sur la figure 6, on a représenté en coupe les montants 1 et 2, qui forment des glissières pour les bords du rideau. Dans ce but, les montants présentent sur leurs faces placées vers le centre de la baie, des fentes 21, 22 dont les bords sont repliés vers l'intérieur du montant pour former des glissières évasées vers l'intérieur.In Figure 6, there is shown in section the uprights 1 and 2, which form slides for the edges of the curtain. For this purpose, the uprights present on their faces placed towards the center of the opening, slots 21, 22 the edges of which are folded inwards towards the inside of the upright to form flared inwards slides.

Le rideau comporte quatre bandes d'écartement dont deux sont disposées sur les bords du rideau et les autres réparties sur la largeur du rideau. Les bandes d'écartement 23, 24 placées sur les bords peuvent aussi former de cette façon des bourrelets servant à maintenir les bords du rideau dans les glissières. Le nombre des bandes dépend de la largeur du rideau, et des sollicitations pour lesquelles il est prévu. Les bandes sont de préférence réparties uniformément sur la largeur du rideau, tant pour l'efficacité que pour l'esthétique.The curtain has four spacer strips, two of which are arranged on the edges of the curtain and the others distributed over the width of the curtain. The spacer strips 23, 24 placed on the edges can also in this way form beads serving to hold the edges of the curtain in the rails. The number of bands depends on the width of the curtain, and the stresses for which it is intended. The strips are preferably distributed uniformly over the width of the curtain, both for efficiency and for aesthetics.
