Description

La présente invention concerne une porte de manutention à rideau relevable étanche. Ces portes, utilisées dans les locaux industriels ou commerciaux, usines, entrepôts, garages, magasins, etc., comportent un rideau mobile pouvant être relevé ou abaissé pour dégager ou obturer une baie dans un mur. Une telle porte comporte un cadre constitué de deux montants latéraux, formant ou comportant chacun une glissière pour le bord du rideau, et le plus souvent une traverse horizontale supérieure joignant les parties supérieures des montants.The present invention relates to a watertight lifting curtain handling door. These doors, used in industrial or commercial premises, factories, warehouses, garages, shops, etc., have a movable curtain that can be raised or lowered to free or close a bay in a wall. Such 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.

La présente invention concerne plus particulièrement un dispositif assurant l'étanchéité entre le bord du rideau et la glissière correspondante, permettant un mouvement silencieux, favorisant le glissement et fournissant une bonne tenue au vent. Le rideau peut être constitué par une bâche souple, en tissu ou en matière plastique, renforcée ou non par des barres d'armature, le rideau pouvant être plié ou enroulé à la partie supérieure de la porte. Le rideau peut aussi être constitué de panneaux rigides articulés les uns aux autres. On comprendra que dans ce dernier cas, le dispositif de l'invention pourrait être appliqué au cas où le déplacement des panneaux ne serait pas vertical.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.

Un but de l'invention est d'obtenir une bonne étanchéité de la porte en position de fermeture. Un autre but de l'invention est d'obtenir un fonctionnement silencieux et un bon glissement des bords du rideau dans les glissières.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.

Dans ce but, l'invention a pour objet une porte de manutention à rideau relevable, comportant deux montants latéraux rigides disposés des deux côtés de l'ouverture d'une baie, formant ou comportant chacun une glissière, et un rideau disposé entre les montants, les bords verticaux du rideau coulissant chacun dans une glissière, caractérisée en ce que chaque glissière comporte une fente verticale formée dans la paroi rigide du montant disposée vers le centre du rideau, délimitée par deux bords, et une bâche d'étanchéité souple joignant sur essentiellement toute la hauteur de la fente les deux bords, de façon à délimiter une poche verticale du côté opposé au centre du rideau prévue pour recevoir un bord du rideau, ce bord étant en appui souple contre le fond de la poche, lequel fond dispose d'un jeu suffisant pour absorber les mouvements et déformations du bord du rideau.To this end, the subject of the invention is a handling door with a lifting curtain, 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 movements and deformations of the edge of the curtain.

On connaît déjà par le brevet US 4.649.981 un rideau isolant dont les bords coulissent dans des glissières latérales, chaque glissière étant formée par une poche longitudinale souple disposée dans un montant rigide, les bords de la poche étant fixés aux bords d'une fente longitudinale destinée à recevoir le bord du rideau. Dans cette proposition, le fond de la poche est fixé à la paroi rigide du montant. Le dispositif décrit a pour objet de retenir les bords du rideau dans les glissières quand le rideau est exposé au vent ou à une autre force exercée dans une direction perpendiculaire au plan du rideau. L'étanchéité peut être obtenue par le glissement du bord du rideau entre deux parois souples appliquées sur les deux faces du rideau. Le dispositif décrit est fragile, et ne peut être appliqué à des portes de manutention. Le fonctionnement est incertain, car le rideau qui s'enroule au-dessus de la porte sort nécessairement des glissières, et il n'est pas évident qu'il puisse se réinsérer correctement lors de la descente. De toutes façons, le problème technique n'est pas le même.Is already known from US Pat. No. 4,649,981 an insulating curtain, the edges of which slide in lateral slides, each slide being formed by a flexible longitudinal pocket arranged in a rigid upright, the edges of the pocket being fixed to the edges of a slot longitudinal intended to receive the edge of the curtain. In this proposal, the bottom of the pocket is fixed to the rigid wall of the upright. The The object of the device described is to retain the edges of the curtain in the guides when the curtain is exposed to wind or another force exerted in a direction perpendicular to the plane of the curtain. Sealing can be obtained by sliding the edge of the curtain between two flexible walls applied to both sides of the curtain. The device described is fragile, and cannot be applied to handling doors. Operation is uncertain, because the curtain that winds above the door necessarily comes out of the rails, and it is not obvious that it can be reinserted correctly during the descent. In any case, the technical problem is not the same.

Dans une forme de réalisation avantageuse, la bâche d'étanchéité souple est munie sur ses deux bords de joncs rectilignes, et les joncs sont fixés aux bords de la glissière. En particulier, la bâche peut être un tube applati, et les joncs sont passés à l'intérieur.In an advantageous embodiment, the flexible sealing sheet is provided on its two edges with straight rods, and the rods are fixed to the edges of the slide. In particular, the cover may be a flattened tube, and the rods are passed inside.

Selon l'invention, on peut prévoir que les bords de la glissière soient garnis d'un profilé en plastique favorisant le glissement du bord du rideau. Avantageusement, le profilé est fixé par encliquetage élastique sur le bord de la glissière. De préférence, le profilé comporte un logement longitudinal pour recevoir ledit jonc.According to the invention, provision can be made for the edges of the slide to be lined with a plastic profile favoring the sliding of the edge of the curtain. Advantageously, the profile is fixed by elastic snap-fastening on the edge of the slide. Preferably, the profile comprises a longitudinal housing for receiving said rod.

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

La figure 1 représente un exemple de porte de manutention à rideau relevable à laquelle peut s'appliquer l'invention (non visible sur ce dessin). Cette porte est constituée de deux montants latéraux 1, 2 réunis à leurs parties supérieures par une traverse 3. Un rideau souple 4 peut obturer ou dégager une baie 5 formée dans un mur 6, par descente ou relevage. Les bords 4a du rideau 4 coulissent dans des glissières 7 formées dans les montants latéraux. Le rideau peut être renforcé par des barres d'armature 8, et dans ce cas, les extrémités des barres peuvent se prolonger à l'intérieur des glissières. L'invention s'applique également au cas où il n'y a pas de barre, ou encore au cas où les extrémités des barres ne pénètrent pas dans les glissières. Le rideau souple 4 peut s'enrouler autour d'un arbre situé par exemple dans la traverse 3, ou peut se replier en accordéon à la partie supérieure de la porte. L'invention s'applique également aux portes comportant un rideau constitué de panneaux rigides juxtaposés ou articulés les uns aux autres, et dont les bords latéraux coulissent dans les glissières.FIG. 1 represents an example of a handling door with a lifting curtain 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 accordion to the upper part of the door. The invention also applies to doors comprising a curtain made up of rigid panels juxtaposed or articulated to one another, and the lateral edges of which slide in the slides.

Sur la coupe de la figure 2, on a représenté le montant rigide 2, qui peut être en métal ou en autre matière, bois ou plastique. Il comporte une ouverture 7 faisant partie de la glissière, formée dans la paroi 9 du montant 2, qui regarde le centre de la porte et séparant cette paroi en deux parties 9a, 9b. Les bords de la paroi 9 peuvent être repliés pour former les bords 7a, 7b de la glissière, comme représenté. Le montant peut être en une seule pièce, mais il est souvent avantageux qu'un côté 2a soit démontable pour faciliter la fabrication et la maintenance. Sur les bords 7a et 7b de la glissière sont fixés les bords 11b et 11c d'une bâche en forme d'une bande 11 d'un tissu plastifié résistant pour former une poche verticale 12. Le bord 4a du rideau 4 est engagé dans cette poche, de façon à être, lorsque la porte est en position de fermeture, en appui élastique contre le fond 11a de la poche. On réalise ainsi l'étanchéité du bord du rideau quand la porte est fermée, et un fonctionnement souple et silencieux en mouvement. La bâche assure aussi un isolement thermique et limite les effets du givre.In the section of Figure 2, there is shown the rigid upright 2, which can be metal or another 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 one 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 tarpaulin 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.

Il est essentiel que le fond 11a de la poche puisse débattre librement en direction opposée de l'ouverture 7 de la glissière, et soit donc à une distance suffisante de la paroi opposée 2b du montant 2 (ou encore qu'il n'y ait pas de paroi du montant dans cette direction).It is essential that 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 wall of the upright in this direction).

Les bords de la bâche souple 11 peuvent être fixés aux bords 7a, 7b de la fente 7 par tous moyens convenables. Un exemple pratique avantageux va être décrit maintenant en regard de la figure 3.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.

La coupe de la figure 3 a été faite au niveau d'une barre d'armature du rideau, dans le cas où celui-ci en comporte. On a représenté seulement sur la figure les bords repliés 7a, 7b, de part et d'autre de la fente 7, des bords 9a, 9b de la paroi 9 du montant 2.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.

Afin de favoriser le glissement, des profilés de glissement 26 en matière plastique sont engagés par déformation et bloqués sur les bords 7a, 7b de la glissière. Ces profilés présentent dans la fente de la glissière une face arrondie 26a très favorable au glissement et supprimant les risques d'accrochage. En outre, ces profilés servent à fixer de façon simple la bâche d'étanchéité. Pour cela, le profilé comporte un logement (longitudinal) 28 avec un passage d'accès 29 étranglé, tandis que les bords de la bâche sont munis d'un jonc rectiligne 25 (bois ou plastique) d'un diamètre supérieur à la largeur du passage étranglé, mais permettant cependant de l'introduire dans le logement 28 par déformation élastique d'au moins une paroi dudit profilé.In order to promote sliding, sliding profiles 26 of plastic material 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. In addition, these profiles are used to simply fix the waterproof cover. For this, 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.

La coupe de la figure 3 montre une façon simple de fixer les joncs 25 à la bâche. Cette dernière est tout simplement constituée d'un tube mis à plat, et les 2 joncs sont simplement engagés dedans.The section of Figure 3 shows a simple way to attach the rods 25 to the tarpaulin. The latter is simply made of a flat tube, and the 2 rods are simply engaged in it.

Sur cette figure, la coupe a été faite par un plan horizontal passant par l'axe d'une barre de renforcement. Dans cet exemple de réalisation, la barre comporte un tube souple 21, par exemple en métal ou en plastique renforcé, d'une longueur peu inférieure à l'écart entre les glissières. Un embout 22 (voir figure 4) est engagé dans le tube souple pour prolonger celui-ci par une partie amincie 22, s'étendant dans un plan vertical. Cette partie amincie 22a est prévue pour se déplacer dans la glissière, et a une épaisseur réduite, assez comparable à celle du rideau. A titre d'exemple, le tube peut avoir un diamètre de 3cm, et la partie amincie 1/2cm. L'embout peut présenter à l'autre extrémité 22b une partie de section réduite avec un épaulement 22c pour obtenir une liaison définie et précise. La liaison peut être obtenue par emmanchement à force, par collage, etc.. L'embout peut être en matière plastique assez rigide pour maintenir le rideau en position dans les glissières sous l'effet du vent, mais cependant assez souple pour se plier et se dégager de la glissière, sous l'effet d'une force anormale, par exemple la percussion d'un véhicule dans le rideau.In this figure, the cut was made by a horizontal plane passing through the axis of a reinforcing bar. In this exemplary embodiment, 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. For example, the tube can have a diameter of 3cm, and the thinned part 1 / 2cm. The end piece may have at the other end 22b a part of reduced section with a shoulder 22c to obtain a defined and precise connection. The 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 rails under the effect of the wind, but nevertheless flexible enough to bend and disengage from the slide, under the effect of an abnormal force, for example the percussion of a vehicle in the curtain.

Comme il est bien connu dans la technique, le rideau peut être garni sur les deux faces, au niveau de la barre de renforcement, par des bandes de tissu plastique ou plastifié 23a, 23b (voir aussi figure 5) qui sont prolongées jusqu'à l'extrémité de l'embout, de façon à l'envelopper complètement par rabattement l'une sur l'autre en 23c. Ces bandes sont soudées l'une à l'autre au-dessus et au-dessous de la barre, formant ainsi un fourreau.As is well known in the art, the curtain can be trimmed on both sides, at the level of the reinforcement 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.

Enfin, comme il est connu dans la technique (voir brevet FR 91-02712), la partie de l'embout située dans la gorge de la glissière, entre les faces arrondies 26a, peut être garnie sur les deux faces, donc en regard des deux faces arrondies 26a, par des patins de glissement 24, avantageusement munis de nervures 24a disposées verticalement. Ces patins réduisent l'usure, facilitent le glissement et s'opposent au mouvement axial de la barre.Finally, as is known in the art (see patent FR 91-02712), 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.
