Description

La présente invention a pour objet une porte de manutention constituée de panneaux qui peuvent se replier, s'enrouler, s'empiler, se juxtaposer, pour laisser passer des véhicules, ou autres engins, pour des usines, des hangars, et autres bâtiments industriels, ou encore des fermetures de garages ou des rideaux protecteurs de magasins ou similaires. L'invention a plus particulièrement pour objet une structure de panneau permettant de réaliser rapidement et simplement des panneaux de toutes dimensions à partir de quelques éléments standards simples.The subject of the present invention is a handling door made up of panels which can be folded up, rolled up, stacked, juxtaposed, to allow vehicles, or other machines to pass, for factories, hangars, and other industrial buildings. , or garage closures or store curtains or the like. The invention more particularly relates to a panel structure making it possible to quickly and simply produce panels of any size from a few simple standard elements.

Les figures 1 et 2 des dessins ci-joints représentent un exemple d'une porte de manutention à laquelle peut s'apliquer l'invention. Cette porte comprend deux montants latéraux verticaux 1, 2 réunis à leurs extrémités supérieures par une traverse horizontale 3. Les montants ont en section une forme générale de U et comportent chacun une glissière verticale 4. Les montants et la traverse sont destinés à être placés autour d'une baie de façon que la porte permette de commander l'ouverture ou la fermeture de la baie. Avantageusement, la surface laissée libre entre les montants et sous la traverse correspond à l'ouverture de la baie, et les montants et la traverse sont placés contre le mur autour de la baie.Figures 1 and 2 of the accompanying drawings show an example of a handling door to which the invention can be applied. This door comprises two vertical lateral uprights 1, 2 joined at their upper ends by a horizontal cross-member 3. The uprights have a general U-shaped cross-section and each comprise a vertical slide 4. The uprights and the cross-member are intended to be placed around a bay so that the door allows the opening or closing of the bay to be controlled. Advantageously, the surface left free between the uprights and under the crosspiece corresponds to the opening of the opening, and the uprights and the crosspiece are placed against the wall around the opening.

La surface d'obturation de la porte est formée par des panneaux 5 articulés entre eux deux à deux par des charnières horizontales, traversées par des axes. Les axes sont des barres de renforcement 6, 7, dont une sur deux est prolongée à l'intérieur de la glissière, à commencer par celle du bas 7A. La longueur des panneaux est sensiblement égale, ou légèrement inférieure, à la largeur de la porte, c'est-à-dire à l'écart disponible entre les montants 1, 2 de façon à ce que les panneaux puissent être repliés entre les montants. L'ouverture de la porte est obtenue en remontant la barre inférieure 7A, dont les extrémités sont prolongées dans les glissières, pour assurer le guidage. La barre inférieure peut être remontée par des sangles, fixées à la barre inférieure, et venant s'enrouler sur un arbre d'enroulement logé de préférence dans la traverse supérieure.The shutter surface of the door is formed by panels 5 hinged together in pairs by horizontal hinges, crossed by axes. The axes are reinforcing bars 6, 7, one in two of which is extended inside the slide, starting with that of the bottom 7A. The length of the panels is substantially equal to, or slightly less than, the width of the door, i.e. the gap available between the uprights 1, 2 so that the panels can be folded between the uprights . The opening of the door is obtained by raising the lower bar 7A, the ends of which are extended in the slides, to provide guidance. The lower bar can be reassembled by straps, fixed to the lower bar, and coming to be wound on a winding shaft preferably housed in the upper crosspiece.

En enroulant les sangles, la barre 7A remonte, ce qui fait plier l'un contre l'autre les deux panneaux inférieurs 5A, 5B, cependant que la barre de charnière 6A qui les réunit et dont la longueur est telle que ses extrémités n'entrent pas dans les glissières 4 des montants, se déporte à l'écart du plan de la porte. Ensuite, la barre inférieure 7A des montants vient en butée contre la barre supérieure 7B dont les extrémités sont engagées dans les glissières et commence à la soulever, et ainsi de suite, jusqu'à ce que les panneaux soient repliés les uns contre les autres, à la partie supérieure de la porte, comme représenté sur la figure 2.By winding the straps, the bar 7A rises, which folds the two lower panels 5A, 5B against each other, while the hinge bar 6A which joins them together and whose length is such that its ends do not not enter the rails 4 of the uprights, offset away from the plane of the door. Then, the lower bar 7A of the uprights abuts against the upper bar 7B whose ends are engaged in the slides and begins to lift it, and so on, until the panels are folded against each other, at the top of the door, as shown in Figure 2.

L'invention s'applique généralement à d'autres types de portes de manutention formées de panneaux articulés entre eux ou non, telles que par exemple celles représentées sur les figures 3 et 4 des dessins.The invention generally applies to other types of handling doors formed by panels hinged together or not, such as for example those shown in Figures 3 and 4 of the drawings.

Sur la figure 3, la porte est dotée de montants latéraux verticaux 1 et 2 comportant chacun une glissière, et les glissières desdits montants 1 et 2 se prolongent vers le haut par des glissières horizontales ou obliques, respectivement 8 et 9. La porte est en outre dotée de panneaux 5 articulés entre eux deux à deux autour de barres de renforcement 7 qui se prolongent jusque dans les glissières. Pour ouvrir la porte, il suffit de tirer vers le haut le panneau supérieur 5C qui entraîne les autres vers les glissières 8 et 9.In FIG. 3, the door is provided with vertical lateral uprights 1 and 2 each comprising a slide, and the slides of said uprights 1 and 2 are extended upwards by horizontal or oblique slides, respectively 8 and 9. The door is additionally provided with panels 5 hinged together in pairs around reinforcing bars 7 which extend into the slides. To open the door, simply pull up the upper panel 5C which drives the others towards the rails 8 and 9.

Sur la figure 4, la porte est dotée de deux montants latéraux verticaux 1 et 2 comportant chacun une glissière 4 dans laquelle coulissent des panneaux 5 non articulés entre eux. Lors de l'ouverture de la porte, les panneaux 5 sont empilés au-dessus de la porte.In FIG. 4, the door is provided with two vertical lateral uprights 1 and 2 each comprising a slide 4 in which panels 5 which are not articulated between them slide. When the door is opened, the panels 5 are stacked above the door.

Par ailleurs, l'application de l'invention n'est pas limitée aux portes à relevage vertical : les panneaux peuvent glisser horizontalement vers les côtés.Furthermore, the application of the invention is not limited to doors with vertical lift: the panels can slide horizontally to the sides.

L'invention a pour objet une porte de manutention constituée de panneaux rigides connectés à des barres de renforcement dont au moins certaines se prolongent jusque dans des glissières, caractérisée en ce que chaque panneau est constitué de deux longerons parallèles disposés au voisinage de ses côtés longitudinaux, chaque longeron comporte sur deux bords longitudinaux opposés des moyens de fixation permettant de fixer sur un bord des moyens de connexion à une barre de renforcement, et sur l'autre bord au moins deux entretoises pour connecter entre eux les deux longerons du panneau, et la surface entre les longerons est garnie de plaques rigides de remplissage. Lesdits moyens de connexion à une barre de renforcement peuvent être des moyens d'articulation.The subject of the invention is a handling door made up of rigid panels connected to reinforcement bars, at least some of which extend into slides, characterized in that each panel consists of two parallel beams arranged in the vicinity of its longitudinal sides , each spar comprises on two opposite longitudinal edges fixing means making it possible to fix on one edge means of connection to a reinforcing bar, and on the other edge at least two spacers for connecting the two spars of the panel to one another, and the surface between the side members is lined with rigid filling plates. Said means of connection to a reinforcing bar can be articulation means.

Les longerons peuvent être en métal, par exemple l'aluminium, en bois ou en matière plastique ou en tout autre matériau. Ils sont disponibles en grande longueur, de sorte que par découpe, on peut constituer très rapidement des panneaux de toutes longueurs. Ainsi, le fabricant d'une porte selon l'invention peut limiter son stock à un nombre restreint d'éléments différents, à savoir : un seul type de longeron, un seul type d'entretoise (si tous les panneaux ont même largeur, ce qui est généralement le cas), un ou plusieurs types de plaques de remplissage (par exemple des plaques transparentes et des plaques opaques), et des moyens d'articulation à fixer aux longerons. Par conséquent, la gestion de ce stock est très simple, et le stock peut plus facilement être minimisé. De plus, la simplicité du montage initial des panneaux, avantageuse en elle-même, a aussi pour effet de réduite la durée et le coût du montage initial.The side members may be made of metal, for example aluminum, of wood or of plastic or any other material. They are available in great lengths, so that by cutting, panels of all lengths can be made very quickly. Thus, the manufacturer of a door according to the invention can limit his stock to a limited number of different elements, namely: a single type of spar, a single type of spacer (if all the panels have the same width, this which is generally the case), one or more types of filling plates (for example transparent plates and opaque plates), and articulation means to be fixed to the side members. Therefore, the management of this stock is very simple, and the stock can more easily be understated. In addition, the simplicity of the initial assembly of the panels, advantageous in itself, also has the effect of reducing the duration and the cost of the initial assembly.

Enfin, cette structure présente aussi un grand intérêt quant à la maintenance des panneaux. En effet, l'utilisateur de la porte peut lui-aussi se constituer un stock de pièces de rechange comprenant les quelques éléments constitutifs des panneaux de façon à réparer rapidement et facilement les panneaux endommagés, par exemple lors de chocs avec des engins de manutention.Finally, this structure is also of great interest for the maintenance of the panels. In fact, the user of the door can also build up a stock of spare parts comprising the few constituent elements of the panels so as to quickly and easily repair damaged panels, for example during impacts with handling equipment.

Avantageusement, les moyens de fixation des longerons sont des moyens d'emboîtement et les extrémités des entretoises ainsi que les moyens de connection aux barres de renforcement présentent des moyens d'emboîtement complémentaires permettant leur assemblage sur les longerons. Dans une forme particulière de l'invention, lesdits moyens d'emboîtement des longerons sont des reliefs en queue d'aronde et lesdits moyens d'emboîtement complémentaires des entretoises et des moyens de connexion aux barres de renforcement sont des saignées en queue d'aronde.Advantageously, the means for fixing the side members are means for interlocking and the ends of the spacers as well as the means for connection to the reinforcement bars have complementary interlocking means allowing their assembly on the side members. In a particular form of the invention, said means for fitting the side members are dovetail reliefs and said means for complementary fitting of the spacers and means for connection to the reinforcement bars are dovetail grooves .

L'invention a aussi pour objet une telle porte, caractérisée en outre en ce que les longerons, entretoises et moyens de connexion aux barres de renforcement présentent une rigidité suffisante pour résister aux effractions et au vent, et une souplesse suffisante pour qu'en cas de choc violent d'un engin de manutention sur un panneau, ledit panneau se disloque par déboîtement des moyens d'emboîtement. En outre, l'invention a pour objet une telle porte, caractérisée en ce que les moyens de fixation entre les longerons et les entretoises d'une part, ainsi que les moyens de fixation entre les longerons et les moyens de connexion aux barres de renforcement d'autre part, ont une résistance suffisante pour résister au vent et aux effractions, mais assez faible pour permettre la dislocation d'un panneau par cassure d'au moins une partie desdits moyens de fixation en cas de choc violent d'un engin de manutention sur ledit panneau.Another subject of the invention is such a door, further characterized in that the longitudinal members, spacers and means for connection to the reinforcement bars have sufficient rigidity to resist break-ins and wind, and sufficient flexibility so that in the event of violent impact of a handling device on a panel, said panel is dislocated by disengagement of the interlocking means. In addition, the invention relates to such a door, characterized in that the fixing means between the side members and the spacers on the one hand, as well as the fixing means between the side members and the connection means to the reinforcing bars. on the other hand, have sufficient strength to withstand wind and break-ins, but weak enough to allow the dislocation of a panel by breakage of at least part of said fixing means in the event of a violent impact from a handling on said panel.

Ainsi, en cas de choc violent d'un engin de manutention sur un panneau, les dégâts sont limités à ce panneau, et éventuellement aux bords adjacents des panneaux voisins. De ce fait, les dégâts sont plus facilement et plus rapidement réparables.Thus, in the event of a violent impact from a handling device on a panel, the damage is limited to this panel, and possibly to the adjacent edges of the neighboring panels. As a result, damage is easier and faster to repair.

Dans une forme particulière de réalisation de l'invention, chaque longeron comporte, sur au moins un de ses deux bords longitudinaux qui sont dotés de moyens de fixation au moins une rainure longitudinale permettant de recevoir une plaque de remplissage. Par ailleurs, chaque entretoise peut comporter au moins une rainure longitudinale disposée dans le plan du panneau, permettant de recevoir une plaque de remplissage dudit panneau. Ainsi, on peut assembler simplement les plaques de remplissage en les glissant dans les rainures en regard des longerons et/ou des entretoises.In a particular embodiment of the invention, each spar comprises, on at least one of its two longitudinal edges which are provided with fixing means at least one longitudinal groove for receiving a filling plate. Furthermore, each spacer may include at least one groove longitudinal disposed in the plane of the panel, for receiving a filling plate of said panel. Thus, one can simply assemble the filler plates by sliding them in the grooves opposite the side members and / or spacers.

D'autres caractéristiques et avantages de l'invention apparaîtront au cours de la description détaillée suivante, donnée à titre d'exemple non limitatif, en regard des dessins joints.Other characteristics and advantages of the invention will appear during the following detailed description, given by way of nonlimiting example, with reference to the accompanying drawings.

La figure 5 représente des panneaux 5 plus particulièrement destinés à être utilisés dans une porte de manutention telle que celle des figures 1 et 2 ou celle de la figure 3.FIG. 5 represents panels 5 more particularly intended for use in a handling door such as that of FIGS. 1 and 2 or that of FIG. 3.

les panneaux 5 comportent chacun deux longerons parallèles 10 représentés avec plus de détails sur la figure 6. Chaque longeron 10 comporte sur deux bords longitudinaux opposés des moyens de fixation, qui sont ici des reliefs en queue d'aronde 11. Dans l'exemple particulier de la figure 6, les longerons 10 comportent en outre sur leurs bords longitudinaux en queue d'aronde une ou plusieurs rainures 12 longitudinales, dont l'utilité sera vue plus loin.the panels 5 each comprise two parallel beams 10 shown in greater detail in FIG. 6. Each beam 10 comprises on two opposite longitudinal edges fastening means, which are here dovetail reliefs 11. In the particular example of Figure 6, the side members 10 further comprise on their longitudinal edges in dovetail one or more longitudinal grooves 12, the usefulness of which will be seen later.

Les deux longerons 10 de chaque panneau 5 sont reliés entre eux par au moins deux entretoises 13, telles que celle qui est représentée sur la figure 7. Chaque entretoise 13 s'étend entre deux extrémités dotées chacune d'une saignée 14 en queue d'aronde, qui reçoit un relief 11 en queue d'aronde d'un longeron 10. En outre, dans l'exemple particulier représenté sur la figure 7, l'entretoise 13 comporte une ou plusieurs rainures longitudinales 15 sur deux côtés opposés, en correspondance avec les rainures longitudinales 12 des longerons 10.The two longitudinal members 10 of each panel 5 are interconnected by at least two spacers 13, such as that which is shown in FIG. 7. Each spacer 13 extends between two ends each provided with a groove 14 at the tail dovetail, which receives a relief 11 at the dovetail of a spar 10. In addition, in the particular example shown in FIG. 7, the spacer 13 comprises one or more longitudinal grooves 15 on two opposite sides, in correspondence with the longitudinal grooves 12 of the side members 10.

Les longerons 10 et les entretoises 13 forment un cadre dont les ouvertures peuvent être garnies de plaques planes rigides de remplissage 16, qui peuvent être en matière plastique, en bois, par exemple en contreplaqué, en verre, en métal, etc. Les plaques de remplissage 16 peuvent être glissées dans les rainures 12 et 15 des longerons et des entretoises. En variante, la plaque de remplissage 16 peut être fixée à l'aide d'un bourrelet périphérique 17 souple ayant un profil sensiblement en forme de H comme représenté sur la figure 10. Le bourrelet 17 est emboîté d'une part sur le côté des longerons 10 et des entretoises 13, puis reçoit la plaque de remplissage 16, d'une façon bien connue.The longitudinal members 10 and the spacers 13 form a frame, the openings of which can be lined with rigid flat filling plates 16, which may be made of plastic, wood, for example plywood, glass, metal, etc. The filling plates 16 can be slid into the grooves 12 and 15 of the side members and spacers. Alternatively, the filling plate 16 can be fixed using a flexible peripheral bead 17 having a substantially H-shaped profile as shown in FIG. 10. The bead 17 is fitted on the one hand on the side of the side members 10 and spacers 13, then receives the filler plate 16, in a well known manner.

Par ailleurs, le côté du longeron 10 opposé aux entretoises 13 reçoit des éléments de charnière 18 et 19 représentés en coupe en détail sur la figures 8 et 9. Chaque élément 18 et 19 comporte une saignée 20 en queue d'aronde, qui permet sa fixation sur les reliefs 11 en queue d'aronde des longerons 10, du côté desdits longerons dirigé vers l'extérieur du panneau 5. Comme représenté sur la figure 5, les éléments 18 et 19 de charnière sont disposés en alternance sur chaque longeron 10, et chaque élément 18 d'un panneau 5 est en regard d'un élément 19 d'un panneau adjacent. Dans l'exemple particulier de la figure 5, les panneaux 5 sont articulés deux à deux sur des barres de renforcement 21, dont au moins certaines coulissent dans des glisssières latérales fixes, comme expliqué ci-dessus en regard des figures 1 à 3. Les éléments19 sont traversés par les barres 21, tandis que les éléments 18 remplissent l'espace entre le panneau 5 où ils sont fixés, et l'élément 19 en regard.Furthermore, the side of the spar 10 opposite the spacers 13 receives hinge elements 18 and 19 shown in section in detail in Figures 8 and 9. Each element 18 and 19 has a groove 20 in dovetail, which allows its attachment to the reliefs 11 at the dovetail of the side members 10, on the side of said side members directed towards the outside of the panel 5. As shown in FIG. 5, the hinge elements 18 and 19 are arranged alternately on each side member 10, and each element 18 of a panel 5 is opposite an element 19 of an adjacent panel. In the particular example of FIG. 5, the panels 5 are articulated two by two on reinforcement bars 21, at least some of which slide in fixed lateral slides, as explained above with reference to FIGS. 1 to 3. The elements 19 are crossed by the bars 21, while the elements 18 fill the space between the panel 5 where they are fixed, and the element 19 opposite.

Dans le cas où les panneaux 5 ne sont pas articulés deux à deux, comme représenté dans l'exemple de la figure 4, chaque panneau 5 peut être fixé à deux barres de renforcement 21 à l'aide des seuls éléments de charnière 19 traversés par les barres, ou par tout autre moyen de fixation.In the case where the panels 5 are not articulated in pairs, as shown in the example of FIG. 4, each panel 5 can be fixed to two reinforcing bars 21 using only the hinge elements 19 traversed by bars, or by any other means of attachment.

Dans tous les cas, il est avantgeux que les extrémités des barres de renforcement 21 qui coulissent dans les glissières fixes de la porte, puissent être rompues avant que d'autres pièces soient brisées ou déformées de façon permanente, en cas de choc d'un engin, de manutention sur un panneau. Ainsi, ledit panneau peut se dégager sans grand dommage. Par exemple les barres de renforcement 21 peuvent présenter une section de moindre résistance entre le bord du panneau et la glissière. En variante, les barres peuvent être suffisamment souples pour être dégagées hors des glissières sous l'effet d'une poussée anormale, sans subir de déformation permanente.In all cases, it is advantageous that the ends of the reinforcement bars 21 which slide in the fixed slides of the door, can be broken before other parts are broken or deformed permanently, in the event of a machine impact, handling on a panel. Thus, said panel can be released without great damage. For example, the reinforcement bars 21 may have a section of least resistance between the edge of the panel and the slide. Alternatively, the bars can be flexible enough to be released from the slides under the effect of an abnormal push, without undergoing permanent deformation.

Les longerons 10, entretoises 13 et éléments de charnière 18 et 19 peuvent être réalisés en matière plastique, par exemple par extrusion ou par moulage. Ils peuvent aussi être réalisés en bois, en métal, par exemple l'aluminium, etc. Ils sont assemblés à frottement, et ils peuvent éventuellement être en outre collés ou soudés ensemble.The longitudinal members 10, spacers 13 and hinge elements 18 and 19 can be made of plastic, for example by extrusion or by molding. They can also be made of wood, metal, for example aluminum, etc. They are assembled by friction, and they can optionally be additionally glued or welded together.

Dans une forme de réalisation avantageuse de l'invention, les reliefs en queue d'aronde 11 des longerons 10 ont une section suffisamment faible pour se rompre lors d'un choc violent, par exemple lorsqu'un engin de manutention accroche un panneau 5. Ainsi, ledit panneau se disloque, et les autres panneaux ne subissent pas d'effort qui risque de les endommager. Eventuellement, seuls les bords adjacents des panneaux voisins risquent d'être endommagés. Il va de soi que la section des reliefs en queues d'aronde 11 doit tout de même être suffisante pour que la panneau 5 résiste aux intempéries (vent) et aux tentatives d'effraction.In an advantageous embodiment of the invention, the dovetail reliefs 11 of the side members 10 have a section that is small enough to break during a violent impact, for example when a handling machine catches a panel 5. Thus, said panel is dislocated, and the other panels do not undergo any effort which risks damaging them. Possibly, only the adjacent edges of the neighboring panels may be damaged. It goes without saying that the section of the dovetail reliefs 11 must still be sufficient for the panel 5 to withstand bad weather (wind) and attempted break-ins.

Dans une autre forme de réalisation avantageuse de l'invention, les longerons 10, entretoises 13 et éléments de charnière 18 et 19 sont assemblés uniquement à frottement, sans collage ni soudure, et ont une souplesse suffisante pour que les reliefs en queue d'aronde 11 se déboîtent des saignées en queue d'aronde 14 et 20 lors d'un choc violent sur un panneau 5, par exemple du fait d'un engin de manutention. Ainsi, ledit panneau se disloque, ce qui limite les dommages à ce panneau, et éventuelllement aux bords adjacents des panneaux voisins. Comme précédemment, il va de soi que le déboîtement ne doit pas être trop facile, de façon que les panneaux résistent aux intempéries (vent) et aux tentatives d'effraction.In another advantageous embodiment of the invention, the side members 10, spacers 13 and hinge elements 18 and 19 are assembled only by friction, without gluing or welding, and have sufficient flexibility so that the dovetail reliefs 11 disengage from the dovetail grooves 14 and 20 during a violent impact on a panel 5, for example due to a handling machine. Thus, said panel is dislocated, which limits damage to this panel, and possibly to the adjacent edges of the neighboring panels. As before, it goes without saying that the dislocation must not be too easy, so that the panels resist weathering (wind) and attempted break-ins.
