Description

La présente invention concerne les portes de manutention, pour usines, entrepots, hangars, magasins, etc., du type comprenant généralement un portique rigide comportant deux montants latéraux vericaux disposés des deux côtés de la porte, formant ou contenant des glissières, et réunis à leurs parties supérieures par une traverse horizontale, et un rideau pouvant descendre ou monter entre les montants pour être ramassé à la partie supérieure, le rideau étant renforcé par des barres d'armature horizontales équidistantes, les bords du rideau et les extrémités des barres d'armature coulissant dans les glissières, les barres étant disposées dans des fourreaux formés par des doubles épaisseurs localisées du rideau.The present invention relates to handling doors, for factories, warehouses, hangars, stores, etc., of the type generally comprising a rigid gantry comprising two vertical lateral uprights disposed on both sides of the door, forming or containing slides, and joined to their upper parts by a horizontal cross member, and a curtain which can descend or rise between the uprights to be picked up at the upper part, the curtain being reinforced by equidistant horizontal reinforcing bars, the edges of the curtain and the ends of the bars frame sliding in the slides, the bars being arranged in sheaths formed by localized double thicknesses of the curtain.

Afin de faciliter le glissement des extrémités des barres dans les glissières, de réduire le bruit et l'usure, on a déjà proposé de garnir les extrémités des barres de renforcement de galets de roulement ou de patins de glissement.In order to facilitate the sliding of the ends of the bars in the slides, to reduce noise and wear, it has already been proposed to garnish the ends of the reinforcing bars with rollers or sliding shoes.

La présente invention a pour objet un patin de glissement perfectionné, pour extrémité de barre de renforcement d'un tel rideau caractérisé en ce que ledit patin a une forme générale d'un demi cylindre, avec des moyens de fixation au rideau, et porte à une de ses extrémités un doigt radial destiné à être engagé vers l'intérieur du fourreau du rideau, pour limiter le déplacement d'une barre d'armature, dont l'extrémité peut venir en butée sur ledit doigt.The present invention relates to an improved sliding pad for the end of the reinforcing bar of such a curtain, characterized in that said pad has the general shape of a half cylinder, with means for fixing to the curtain, and carries one of its ends a radial finger intended to be engaged towards the inside of the sheath of the curtain, in order to limit the displacement of a rebar, the end of which can abut on said finger.

L'invention a également pour objet une porte de manutention comportant au moins un tel patin. Cette disposition permet un bon glissement du bord du rideau dans la glissière, en évitant une déchirure du rideau, et évite que la barre vienne buter et frotter contre le fond de la glissière.The invention also relates to a handling door comprising at least one such pad. This arrangement allows a good sliding of the edge of the curtain in the slide, avoiding a tearing of the curtain, and prevents the bar from abutting and rubbing against the bottom of the slide.

Avantageusement, la surface extérieure de la partie semi cylindrique est munie de nervures orientées perpendiculaires à l'axe du cylindre.Advantageously, the outer surface of the semi-cylindrical part is provided with ribs oriented perpendicular to the axis of the cylinder.

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 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 which follows, given by way of nonlimiting example, with reference to the attached drawings, and which will make it clear how the invention can be implemented.

L'invention s'applique à toutes sortes de portes de manutention comportant un rideau renforcé par des barres d'armature horizontales, les bords du rideau et les extrémités des barres étant guidées dans des glissières latérales verticales. Un exemple d'une telle porte est représenté sur la figure 1.The invention applies to all kinds of handling doors comprising a curtain reinforced by horizontal reinforcing bars, the edges of the curtain and the ends of the bars being guided in vertical lateral slides. An example of such a door is shown in Figure 1.

Elle comprend un portique formé par deux montants latéraux 1, 2 réunis à leur partie supérieure par une traverse 3 formée par une poutre à section en U renversé. Cette traverse abrite un arbre d'enroulement, et un moteur électrique pour l'actionner, avec les accessoires habituels tels que fin de course, contacts, etc. Des exemples d'organes d'actionnement et accessoires divers de la porte sont décrits en détail dans les brevets EP-0 254 639 et US-4 828 003. Un rideau 4 est accroché par son bord supérieur au fond de la traverse 3. Le rideau est renforcé par des barres d'armature 5 logées dans des fourreaux 6 constitués chacun par une double épaisseur locale du rideau. Pour relever le rideau, des sangles 7 sont fixées à la barre inférieure 5A, et passent dans des boucles 8 fixées aux autres barres. Les sangles sont fixées à l'arbre. Quand celui-ci est mis en rotation, les sangles s'enroulent et relèvent le rideau qui se plie en accordéon. En sens inverse, le rideau descend. Un exemple d'un tel rideau repliable en accordéon est divulgué dans la demande de brevet EP-0 412 857 et dans le brevet US-5 072 767.It comprises a gantry formed by two lateral uprights 1, 2 joined at their upper part by a cross member 3 formed by a beam with inverted U-section. This cross-member houses a winding shaft, and an electric motor to activate it, with the usual accessories such as limit switches, contacts, etc. Examples of various actuators and accessories for the door are described in detail in patents EP-0 254 639 and US-4 828 003. A curtain 4 is hooked by its upper edge to the bottom of the cross-member 3. The curtain is reinforced by reinforcing bars 5 housed in sheaths 6 each consisting of a double local thickness of the curtain. To raise the curtain, straps 7 are fixed to the lower bar 5A, and pass through loops 8 fixed to the other bars. The straps are attached to the tree. When it is rotated, the straps are rolled up and raise the curtain which folds into an accordion. In the opposite direction, the curtain goes down. An example of such a folding accordion curtain is disclosed in patent application EP-0 412 857 and in patent US-5,072,767.

Les deux bords du rideau, avce les extrémités correspondantes des barres de renforcement sont guidés dans des glissières formées ici par les montants latéraux verticaux 1 et 2. Chaque montant comporte un fond 10 et deux ailes 11, 12. Les bords des ailes peuvent être repliés, avec un pli 13, 14, comme représenté, ou comporter d'autres pliages, pour raidir la glissière, et/ou réduire l'usure du rideau contre les bords des glissières. Chaque pli 13, 14 peut former une plaque sensiblement perpendiculairement au rideau, ou plus généralement non perpendiculaire au rideau.The two edges of the curtain, with the corresponding ends of the reinforcing bars are guided in slides formed here by the vertical lateral uprights 1 and 2. Each upright has a bottom 10 and two wings 11, 12. The edges of the wings can be folded , with a fold 13, 14, as shown, or include other folds, to stiffen the slide, and / or reduce the wear of the curtain against the edges of the slides. Each fold 13, 14 can form a plate substantially perpendicular to the curtain, or more generally not perpendicular to the curtain.

Selon une disposition avantageuse de la présente invention, la longueur des barres est inférieure à la largeur du rideau, tout en étant supérieure à l'écart entre les glissières, pour assurer le guidage.According to an advantageous arrangement of the present invention, the length of the bars is less than the width of the curtain, while being greater than the distance between the slides, to provide guidance.

Afin de protéger les bords du rideau, au droit des fourreaux 6, et afin de maintenir les barres à la bonne position, pour éviter que les extrémités n'aillent frotter contre le fond des glissières, il est prévu, conformément à la présente invention, de placer contre chaque fourreau, en regard de l'extrémité de la barre, quand elle est centrée à la bonne position, un patin 15 ayant avantageusement une forme hémicylindrique, fixé au rideau, par exemple par des rivets placés dans des trous 16 prévus dans le patin, au-dessus et au-dessous du fourreau. Le patin 15 comporte un doigt radial 17 dirigé vers l'intérieur du fourreau, soit en passant par une échancrure 18 formée dans la paroi du fourreau, soit au-delà du bord du rideau si celui-ci ne s'étend pas au-delà de l'extrémité de la barre. Ce patin est placé du côté du rideau qui est généralement sollicité contre un même bord de la glissière, sous l'effet du vent, ou d'un différentiel de pression. Il peut être en matière plastique, caoutchouc, bois, etc, de préférence pas métallique puisqu'il frotte contre le métal, afin d'éviter usure, rayures et bruit. Il est d'ailleurs possible de placer un patin de chaque côté si c'est nécessaire. On formera une échancrure de chaque côté. Les doigts 17, selon la forme se placeront l'un à côté de l'autre, ou se superposeront, ou on en supprimera un. Le patin maintient aussi la barre en position pour qu'elle n'aille pas frotter le fond de la glissière. L'effort correspondant est très limité, puisque la barre en principe ne reçoit aucune sollicitation longitudinale.In order to protect the edges of the curtain, in line with the sleeves 6, and in order to maintain the bars in the correct position, to prevent the ends from rubbing against the bottom of the slides, provision is made, in accordance with the present invention, placing against each sheath, facing the end of the bar, when it is centered in the correct position, a shoe 15 advantageously having a semi-cylindrical shape, fixed to the curtain, for example by rivets placed in holes 16 provided in the skate, above and below the scabbard. The shoe 15 has a radial finger 17 directed towards the inside of the sheath, either by passing through a notch 18 formed in the wall of the sheath, or beyond the edge of the curtain if the latter does not extend beyond from the end of the bar. This pad is placed on the side of the curtain which is generally pressed against the same edge of the slide, under the effect of the wind, or a pressure differential. It can be made of plastic, rubber, wood, etc., preferably not metallic since it rubs against the metal, in order to avoid wear, scratches and noise. It is also possible to place a skate on each side if necessary. We will form a notch on each side. The fingers 17, depending on the shape, will be placed one next to the other, or will be superimposed, or one will be deleted. The shoe also keeps the bar in position so that it does not rub against the bottom of the slide. The corresponding effort is very limited, since the bar in principle receives no longitudinal stress.

Dans une forme de réalisation avantageuse de l'invention, la face extérieure du patin est munie de nervures 19 ou autres reliefs analogues perpendiculaires à l'axe de la barre, c'est-à-dire, des nervures verticales, dans le sens du bords des glissières. Ces nervures coopèrent avec les bords 13, 14 des glissières, pendant les mouvements de montée et de descente du rideau, pour s'opposer à un éventuel déport du rideau, sous l'effet par exemple d'un vent oblique, d'une bourrasque tourbillonnaire, etc. D'une manière générale, selon une caractéristique avantageuse de l'invention, le bord 13 de la glissière sur lequel vient glisser et s'appuyer le patin est muni d'un retour favorisant le mouvement dans le sens vertical et le rendant difficile dans le sens horizontal.In an advantageous embodiment of the invention, the outer face of the shoe is provided with ribs 19 or other similar reliefs perpendicular to the axis of the bar, that is to say, vertical ribs, in the direction of edges of slides. These ribs cooperate with the edges 13, 14 of the slides, during the movements of raising and lowering of the curtain, in order to oppose a possible offset of the curtain, under the effect for example of an oblique wind, of a gust. vortex, etc. In general, according to an advantageous characteristic of the invention, the edge 13 of the slide on which the shoe slides and rests is provided with a return promoting movement in the vertical direction and making it difficult in the horizontal direction.

L'invention s'applique évidemment à d'autres portes à rideau, telles que les portes à enroulement. Dans ces portes, c'est le rideau lui-même qui s'enroule sur un arbre.The invention obviously applies to other curtain doors, such as roll-up doors. In these doors, the curtain itself is rolled up on a tree.

Dans une forme de réalisation avantageuse de la porte selon l'invention, le bord du rideau, qui est souple, se prolonge au-delà de l'extrémité de la barre et peut donc venir en frottement sans inconvénient, contre le fond de la glissière et assurer l'étanchéité entre les deux côtés de la porte.In an advantageous embodiment of the door according to the invention, the edge of the curtain, which is flexible, extends beyond the end of the bar and can therefore come into friction without disadvantage, against the bottom of the slide and seal between the two sides of the door.
