Description

La présente invention a pour objet un rideau souple pour porte dite porte "accordéon".The present invention relates to a flexible curtain for a door known as an "accordion" door.

De telles portes sont largement utilisées aussi bien par les particuliers que dans les usines, ateliers, magasins ... Elles se distinguent par un rideau susceptible d'être relevé en se repliant en accordéon.Such doors are widely used both by individuals and in factories, workshops, stores ... They are distinguished by a curtain that can be raised by folding in accordion.

Un tel rideau est essentiellement constitué d'un tablier A en un matériau souple coopérant avec des éléments raidisseurs transversaux B notamment tubulaires fixés au tablier A à intervalles réguliers. Le rideau A est le plus souvent constitué d'une toile en fibre polyester enduite de PVC du type bâche de camion.Such a curtain essentially consists of an apron A of a flexible material cooperating with transverse stiffening elements B, in particular tubular, fixed to the apron A at regular intervals. The curtain A is most often made of a polyester fiber canvas coated with PVC of the truck tarpaulin type.

Le tablier A est mobile en translation verticale selon la double flèche I dans un bâti fixé à la porte non représentée qui est schématiquement constitué par deux montants verticaux C et une poutre horizontale D à section en forme de U.The deck A is movable in vertical translation according to the double arrow I in a frame fixed to the door not shown which is schematically constituted by two vertical uprights C and a horizontal beam D with U-shaped section.

Des sangles E parallèles entre elles, du type sangles de ceinture de sécurité de véhicules automobiles cheminent sur l'une des faces du rideau A, sont fixées à la partie inférieure F de celui-ci, notamment à l'élément raidisseur inférieur B′, et sont susceptibles de s'enrouler autour d'un arbre horizontal rotatif G monté à la partie supérieure de la porte, dans la poutre D de façon à permettre de relever le rideau en le repliant en accordéon. L'arbre rotatif G peut être commandé manuellement, ou à l'aide d'un moteur non représenté.Straps E parallel to each other, of the type for seat belts of motor vehicles run on one of the faces of the curtain A, are fixed to the lower part F thereof, in particular to the lower stiffening element B ′, and are capable of being wound around a rotary horizontal shaft G mounted at the upper part of the door, in the beam D so as to allow the curtain to be raised by folding it in accordion. The rotary shaft G can be controlled manually, or using a motor not shown.

Des éléments de guidage et de maintien J des sangles E sont fixés de préférence à intervalles réguliers sur l'une des faces du rideau et constituent des "passe-sangles" susceptibles de permettre le mouvement susmentionné du rideau.Guiding and holding elements J of the straps E are preferably fixed at regular intervals on one of the faces of the curtain and constitute "strap-throughs" capable of allowing the abovementioned movement of the curtain.

Les rideaux susmentionnés peuvent être dotés de zones transparentes en PVC formant des hublots.The aforementioned curtains may have transparent PVC areas forming portholes.

Malgré leurs avantages, de tels rideaux ne sont pas sans présenter de nombreux inconvénients liés avant tout au mode de mise en place et de maintien des éléments raidisseurs.Despite their advantages, such curtains are not without presenting numerous drawbacks linked above all to the method of positioning and maintaining the stiffening elements.

Pour réaliser cette opération, on utilise classiquement deux procédés :To carry out this operation, two methods are conventionally used:

Le premier de ces procédés consiste à rapporter par soudure des bandes de toile K sur la surface du tablier A de façon à former des fourreaux susceptibles de recevoir les éléments raidisseurs B.The first of these methods consists in bringing strips of fabric K onto the surface of the deck A by welding so as to form sheaths capable of receiving the stiffening elements B.

Le second procédé consiste à fabriquer le tablier A à partir de lés individuels A′ soudés entre eux à leurs extrémités selon deux lignes parallèles L de façon à définir également des fourreaux susceptibles de recevoir les éléments raidisseurs B.The second method consists in manufacturing the apron A from individual strips A ′ welded together at their ends along two parallel lines L so as to also define sleeves capable of receiving the stiffening elements B.

Dans les deux cas, les éléments raidisseurs B, après avoir été glissés dans les fourreaux, doivent être maintenus transversalement, soit par un boulonnage traversant le tablier et les éléments raidisseurs, soit, dans le cas où les éléments raidisseurs sont tubulaires, par des bouchons de gros diamètre mis en place à l'extrémité de ces éléments.In both cases, the stiffening elements B, after having been slid into the sleeves, must be held transversely, either by bolting through the deck and the stiffening elements, or, in the case where the stiffening elements are tubular, by plugs wholesale diameter set up at the end of these elements.

La confection de tels rideaux de l'art antérieur est particulièrement longue et incommode, donc coûteuse, étant donné qu'elle nécessite des tables de grande surface et oblige à mettre en oeuvre des opérations de manutention importantes : de plus, la soudure des lés intermédiaires oblige à faire appel à des soudeuses du type "col de cygne" engendrant là encore des difficultés importantes.The manufacture of such curtains of the prior art is particularly long and inconvenient, therefore costly, since it requires large tables and requires the implementation of large handling operations: moreover, the welding of the intermediate strips requires the use of "swan neck" type welders again causing significant difficulties.

En outre, il arrive relativement fréquemment que le tablier soit percé ou déchiré par usure ou accident, notamment dans les zones formant hublots qui sont plus vulnérables ; des opérations de réparation sont alors nécessaires : celles-ci sont particulièrement coûteuses et incommodes étant donné que, hormis pour de petits trous ou accrocs, seule une soudure par haute fréquence (soudure à coeur des PVC) donne satisfaction dans le temps. Ceci implique donc un démontage complet du rideau et un retour en atelier de confectionnement.In addition, it happens relatively frequently that the apron is punctured or torn by wear or accident, especially in the areas forming windows which are more vulnerable; repair operations are then necessary: these are particularly costly and inconvenient since, apart from small holes or snags, only high frequency welding (welding at the heart of PVC) gives satisfaction over time. This therefore implies a complete dismantling of the curtain and a return to the garment workshop.

La présente invention a pour objet de remédier à cet inconvénient en proposant un rideau souple du type susmentionné, destiné à des portes dites portes "accordéon" susceptibles d'être fabriquées rapidement et facilement, en n'utilisant qu'une main-d'oeuvre minimale, et d'être réparées, sans entraîner des frais trop importants.The object of the present invention is to remedy this drawback by proposing a flexible curtain of the aforementioned type, intended for doors known as "accordion" doors capable of being manufactured quickly and easily, using only one workforce. minimal, and to be repaired, without incurring excessive costs.

Conformément à l'invention, ce rideau est caractérisé en ce que le tablier est constitué par l'assemblage de lés montés amovibles et munis à leurs extrémités de renflements transversaux coopérant avec des rainures formant glissières prévues à cet effet dans des profilés rigides constituant les éléments raidisseurs.According to the invention, this curtain is characterized in that the apron is constituted by the assembly of removable mounted strips and provided at their ends with transverse bulges cooperating with grooves forming slides provided for this purpose in rigid profiles constituting the elements stiffeners.

Il est clair que la fabrication et l'assemblage de tels rideaux est particulièrement aisé ; leur démontage peut également être effectué très rapidement, même par un personnel non spécialisé, compte tenu du caractère amovible des lés et il est possible soit d'effectuer sur place les réparations nécessaires, soit si nécessaire de remplacer un ou plusieurs lés lorsqu'ils s'avèrent trop détériorés.It is clear that the manufacturing and the assembly of such curtains is particularly easy; they can also be dismantled very quickly, even by non-specialized personnel, taking into account the removable nature of the strips and it is possible either to carry out the necessary repairs on the spot, or if necessary to replace one or more strips when they are prove to be too deteriorated.

Selon une autre caractéristique de l'invention, les profilés raidisseurs sont constitués par des éléments de section essentiellement circulaire ou ovale munie sur leur périphérie de rainures de montage longitudinales diamétralement opposées destinées à coopérer avec les renflements de lés contigus.According to another characteristic of the invention, the stiffening profiles are constituted by elements of essentially circular or oval section provided on their periphery with diametrically opposite longitudinal mounting grooves intended to cooperate with the bulges of contiguous strips.

Compte tenu du fait que de tels rideaux sont fréquemment destinés à être exposés à des vents ou des pressions importantes, il est essentiel de pouvoir orienter les profilés raidisseurs suivant l'axe offrant le plus d'inertie à la flexion ; à cet effet, les profilés raidisseurs ont de préférence une section ovale sur le plus petit diamètre de laquelle sont opposées les deux rainures de montage.Given the fact that such curtains are frequently intended to be exposed to strong winds or pressures, it is essential to be able to orient the stiffening sections along the axis offering the most inertia to bending; for this purpose, the stiffening profiles preferably have an oval section on the smallest diameter from which the two mounting grooves are opposite.

Selon une autre caractéristique l'invention, les renflements transversaux des lés sont constitués par les extrémités de ces derniers, respectivement rabattues autour d'un jonc de retenue longitudinal et maintenues dans cette position, notamment par soudage.According to another characteristic of the invention, the transverse bulges of the strips are formed by the ends of the latter, respectively folded down around a longitudinal retaining rod and held in this position, in particular by welding.

Il est clair que la confection de tels lés peut être particulièrement rapide et peu onéreuse ; en outre il est possible de confectionner le rideau à partir de lés de grandes longueurs.It is clear that the preparation of such strips can be particularly rapid and inexpensive; in addition it is possible to make the curtain from strips of great lengths.

Selon une autre caractéristique de l'invention, les profilés raidisseurs sont munis sur leur périphérie d'une rainure de positionnement essentiellement similaire aux rainures de montage entre lesquelles elle est située, parallèlement à celles-ci, et destinée à coopérer avec des éléments de guidage et de maintien des sangles.According to another characteristic of the invention, the stiffening profiles are provided on their periphery with a positioning groove essentially similar to the mounting grooves between which it is located, parallel to these, and intended to cooperate with elements for guiding and holding the straps.

Ces éléments de guidage et de maintien des sangles peuvent être constitués par des pattes en forme de U définissant des passe-sangles dont les extrémités sont munies de bourrelets susceptibles de coopérer avec les rainures de positionnement.These elements for guiding and holding the straps can be constituted by U-shaped lugs defining strap passes, the ends of which are provided with beads capable of cooperating with the positioning grooves.

De telles pattes peuvent être très simplement enfilées dans les rainures de positionnement des éléments raidisseurs puis amenées par glissement dans la position souhaitée avant d'introduire les sangles.Such tabs can be very simply threaded into the positioning grooves of the stiffening elements and then brought by sliding into the desired position before introducing the straps.

L'invention n'est pas limitée à de tels éléments en forme de U et il est également possible pour augmenter l'inertie de choisir des éléments de guidage et de maintien constitués par un profilé longitudinal susceptible d'être glissé et maintenu dans les rainures de positionnement et comportant des fentes permettant le passage de la sangle.The invention is not limited to such U-shaped elements and it is also possible to increase the inertia to choose guiding and holding elements constituted by a longitudinal profile capable of being slid and held in the grooves positioning and having slots allowing the passage of the strap.

Bien entendu, le rideau conforme à l'invention peut comporter des lés au moins partiellement transparents, formant hublots, de manière à définir les zones de visibilité, constituées notamment en PVC transparent.Of course, the curtain according to the invention may include at least partially transparent strips, forming portholes, so as to define the visibility zones, made in particular of transparent PVC.
