On a montré en figures 2a et 2b, les lames 9, 10 du dispositif de guidage 8, prévues sur le montant 2, qui sont réalisées dans un profil en forme de L ou de U, comportant des caractéristiques élastiques suffisantes pour pouvoir se courber ou se déformer lorsqu'un effort extérieur est appliqué, soit sur le rideau souple 5, soit sur ledit dispositif de guidage 8.FIGS. 2a and 2b show the blades 9, 10 of the guide device 8, provided on the upright 2, which are produced in an L-shaped or U-shaped profile, having sufficient elastic characteristics to be able to bend or deform when an external force is applied, either on the flexible curtain 5 or on said guide device 8.
Chaque lame 9, 10 présente une première paroi verticale 12 qui est reliée à une seconde paroi verticale 13, par un voile 14 disposé dans un plan sensiblement perpendiculaire aux dites parois.Each blade 9, 10 has a first vertical wall 12 which is connected to a second vertical wall 13, by a web 14 arranged in a plane substantially perpendicular to said walls.
La paroi verticale 12 de chaque lame 9, 10 peut être, mais de manière non obligatoire, disposée dans un plan perpendiculaire au voile 14 et à la face d'appui 19 du montant vertical 2 de la porte 1.The vertical wall 12 of each blade 9, 10 can be, but not necessarily, arranged in a plane perpendicular to the web 14 and to the bearing face 19 of the vertical upright 2 of the door 1.
En variante la paroi verticale 12 de chaque lame 9, 10 peut présenter un profil courbe ou incliné par rapport au voile 14 et à la face d'appui 19 du montant vertical 2.As a variant, the vertical wall 12 of each blade 9, 10 may have a curved or inclined profile relative to the web 14 and to the bearing face 19 of the vertical upright 2.
La paroi verticale 12 de chaque lame 9, 10 à profil courbe ou incliné, est dirigée en direction de la paroi verticale 13 pour définir avec la paroi 12 de l'autre lame une glissière 11 à profil évasé sur toute sa hauteur.The vertical wall 12 of each blade 9, 10 with a curved or inclined profile, is directed in the direction of the vertical wall 13 to define with the wall 12 of the other blade a slide 11 with a flared profile over its entire height.
Ainsi, la paroi verticale 12 de chaque lame 9, 10 est préalablement courbée ou inclinée lors de sa fabrication dans une direction qui est identique à celle de sa déformation éventuelle lorsqu'un effort extérieur est appliqué, soit sur le rideau souple 5, soit sur le dispositif de guidage 8.Thus, the vertical wall 12 of each blade 9, 10 is previously curved or inclined during its manufacture in a direction which is identical to that of its possible deformation when an external force is applied, either on the flexible curtain 5, or on the guide device 8.
La paroi 13 est disposée dans un plan vertical et perpendiculaire à celui contenant la face d'appui 19 du montant vertical 2 de la porte 1.The wall 13 is arranged in a vertical plane and perpendicular to that containing the bearing face 19 of the vertical upright 2 of the door 1.
Les lames 9 et 10 présentent à l'extérieur du profilé, et sur toute la hauteur des parois 12 et 13, des lèvres 20 et 21 disposées au niveau de la jonction entre lesdites parois et le voile 14.The blades 9 and 10 have on the outside of the profile, and over the entire height of the walls 12 and 13, lips 20 and 21 arranged at the junction between said walls and the web 14.
Les lèvres 21 et 21 assurent une étanchéité aux poussières entre les lames 9, 10 et la face d'appui 19 du montant 2 de la porte 1. Les lèvres 20 et 21 peuvent être rapportées sur le profil des lames 9, 10 par co-extrusion dans une matière plastique différente de celle desdites lames qui est plus souple et qui assure une meilleure étanchéité entre lesdites lames et la face d'appui 19 du montant 2.The lips 21 and 21 provide a dustproof seal between the blades 9, 10 and the bearing face 19 of the upright 2 of the door 1. The lips 20 and 21 can be attached to the profile of the blades 9, 10 by co- extrusion in a plastic material different from that of said blades which is more flexible and which ensures a better seal between said blades and the bearing face 19 of the upright 2.
Les lames 9 et 10 sont retenues sur le montant 2 de manière que chaque paroi verticale 12 soit placée l'une en face de l'autre pour constituer la glissière de guidage 11 , tandis que chaque voile 14 vient contre la face d'appui 19 dudit montant.The blades 9 and 10 are retained on the upright 2 so that each vertical wall 12 is placed one opposite the other to constitute the guide slide 11, while each sail 14 comes against the bearing face 19 said amount.
On note que la paroi 12 de chaque lame 9, 10 présente par rapport au voile 14 une largeur plus grande que celle de la paroi verticale 13, permettant un meilleur guidage du rideau souple 5 et des traverses 7 lors des déplacements.Note that the wall 12 of each blade 9, 10 has a greater width than the wall 14 than that of the vertical wall 13, allowing better guidance of the flexible curtain 5 and crosspieces 7 during movement.
Chaque lame 9 et 10 est retenue dans sa partie supérieure sur le montant 2 par un axe de fixation 15 qui est constitué par un boulon 16 traversant le voile 14 et la face d'appui dudit montant, et un écrou 17 coopérant avec la partie filetée du boulon.Each blade 9 and 10 is retained in its upper part on the upright 2 by a fixing pin 15 which is constituted by a bolt 16 passing through the web 14 and the bearing face of said upright, and a nut 17 cooperating with the threaded part of the bolt.
A l'opposé de l'axe 15, les parties inférieures des lames 9 et 10 sont maintenues éloignées l'une de l'autre par l'intermédiaire d'un autre axe de fixation 18 identique à celui 15, et solidaires du montant 2.Opposite the axis 15, the lower parts of the blades 9 and 10 are kept distant from one another by means of another fixing axis 18 identical to that 15, and integral with the upright 2 .
On note que le nombre d'axes de fixation des lames 9 et 10 contre le montant 2 peut varier en fonction de la hauteur desdites lames et de la rigidité de la liaison à obtenir.It is noted that the number of axes of attachment of the blades 9 and 10 against the upright 2 can vary depending on the height of said blades and the rigidity of the connection to be obtained.
En figure 3 on a montré la partie supérieure des lames 9, 10, solidaire du montant vertical 2, dont chaque paroi 12 présente un prolongement 22 qui est incliné par rapport à ladite paroi en direction de l'extérieur de chaque lame.In Figure 3 there is shown the upper part of the blades 9, 10, integral with the vertical upright 2, each wall 12 has an extension 22 which is inclined relative to said wall towards the outside of each blade.
Le prolongement 22 est obtenu lors de la fabrication de chaque lame 9, 10 de manière que la glissière de guidage 11 présente, lors de la fixation desdites lames l'une en face de l'autre sur le montant 2 dans sa partie supérieure, un profil évasé en portion de cône. Ainsi, chaque prolongement 22 est incliné en direction de l'extérieur de chaque lame 9, 10 par rapport à la paroi 12 correspondante, pour facilité la réintroduction du rideau souple 5 après dégondage à l'intérieur de la glissière de guidage 11.The extension 22 is obtained during the manufacture of each blade 9, 10 so that the guide slide 11 has, during the fixing of said blades one opposite the other on the upright 2 in its upper part, a flared profile in cone portion. Thus, each extension 22 is inclined in the direction of the exterior of each blade 9, 10 relative to the corresponding wall 12, to facilitate the reintroduction of the flexible curtain 5 after unfolding inside the guide rail 11.
Chaque prolongement 22 présente une certaine souplesse élastique pour pouvoir se débattre latéralement par rapport à la paroi 12 et au montant 2, pour permettre l'introduction du rideau souple 5 de l'extérieur vers l'intérieur de la glissière 11.Each extension 22 has a certain elastic flexibility in order to be able to struggle laterally with respect to the wall 12 and to the upright 2, to allow the introduction of the flexible curtain 5 from the outside towards the inside of the slide 11.
On note que plus la longueur du prolongement 22 est grande, c'est à dire que plus le prolongement 22 s'étend au-dessus de la paroi 12, plus sa souplesse est accrue et facilitera la réintroduction des traverses horizontales de raidissement 7 et du rideau souple 5 à l'intérieur de la glissière de guidage 11.Note that the greater the length of the extension 22, that is to say that the more the extension 22 extends above the wall 12, the more its flexibility is increased and will facilitate the reintroduction of the horizontal stiffening crosspieces 7 and of the flexible curtain 5 inside the guide rail 11.
Les prolongements 22 de chaque paroi 12 sont situés au-dessus du dernier axe de fixation supérieur 15, permettant la retenue de chaque lame 9, 10 contre la face d'appui 19 du montant 2 de la porte 1.The extensions 22 of each wall 12 are located above the last upper fixing axis 15, allowing the retention of each blade 9, 10 against the bearing face 19 of the upright 2 of the door 1.
On remarque que le voile 14 présente un pan incliné 23 dont la partie la plus haute se trouve au niveau de la ligne de raccordement entre le prolongement 22 et la paroi 12.It is noted that the web 14 has an inclined face 23, the highest part of which is at the level of the connection line between the extension 22 and the wall 12.
Ainsi, la hauteur de la paroi 13, se raccordant au niveau de la partie la plus basse du pan incliné 23 du voile 14, est inférieure à celle de la paroi 12 facilitant l'arrivée des éléments de guidage du rideau souple 5 contre le prolongement 22, lorsque ses derniers se trouvent à l'extérieur de la glissière 11.Thus, the height of the wall 13, connecting at the lowest part of the inclined face 23 of the web 14, is less than that of the wall 12 facilitating the arrival of the guide elements of the flexible curtain 5 against the extension 22, when its last ones are outside the slide 11.
De plus, le pan incliné 23 évite de déchirer et de détériorer les éléments de guidage du rideau souple 5 lors de sa réintroduction dans la glissière de guidage 11.In addition, the inclined face 23 avoids tearing and damaging the guide elements of the flexible curtain 5 when it is reintroduced into the guide slide 11.
En figure 4 on a représenté, par exemple, la déformation élastique de la paroi verticale 12 par rapport au voile 14 solidaire du montant 2 de la lame 9 lorsqu'un effort extérieur de pression est appliqué sur le rideau souple 5.FIG. 4 shows, for example, the elastic deformation of the vertical wall 12 relative to the web 14 secured to the upright 2 of the blade 9 when an external pressure force is applied to the flexible curtain 5.
On note que seule la paroi verticale 12 droite, courbée ou inclinée par rapport au voile 14 et sur toute la hauteur de la lame 9, subit une déformation élastique qui est dirigée suivant une direction semblable à celle de l'effort extérieur de pression.It is noted that only the straight vertical wall 12, curved or inclined relative to the web 14 and over the entire height of the blade 9, undergoes an elastic deformation which is directed in a direction similar to that of the external pressure force.
La déformation élastique de la paroi 12 droite, courbée ou inclinée par rapport au voile 14 est généralement dirigée en direction de l'extérieur de la glissière 11 pour permettre le dégondage des traverses horizontales de raidissement 7 et du rideau souple 5.The elastic deformation of the straight wall 12, curved or inclined relative to the web 14 is generally directed in the direction of the exterior of the slide 11 to allow the horizontal stiffening cross-members 7 and the flexible curtain 5 to unfasten.
Lorsque la paroi 12 présente un profil courbe ou incliné par rapport au voile 14, la déformation élastique est dirigée dans le prolongement du profil courbe ou incliné, afin de facilité l'expulsion des traverses horizontales de raidissement 7 et du rideau souple 5 de la glissière 11. On constate que la matière utilisée pour chaque lame 9 et 10 permet à la paroi 12 de subir une déformation élastique sous la pression d'un effort extérieur et de revenir dans sa position d'origine sans détérioration.When the wall 12 has a curved or inclined profile relative to the web 14, the elastic deformation is directed in the extension of the curved or inclined profile, in order to facilitate the expulsion of the horizontal stiffening crosspieces 7 and of the flexible curtain 5 of the slide 11. It is found that the material used for each blade 9 and 10 allows the wall 12 to undergo elastic deformation under the pressure of an external force and to return to its original position without deterioration.
En effet, la déformation élastique des lames 9 et 10 lors, par exemple, d'un blocage du rideau souple 5, ou d'un choc latéral, permet le dégondage des traverses horizontales de raidissement 7 sans risque de détérioration de ces dernières et desdites lames.Indeed, the elastic deformation of the blades 9 and 10 during, for example, a blockage of the flexible curtain 5, or a side impact, allows the unfolding of the horizontal stiffening crosspieces 7 without risk of deterioration of the latter and of said blades.
Dans tous les cas, la paroi 12 de chaque lame 9, 10 doit être capable de se déformer et d'atteindre une flèche de valeur déterminée sans subir de déformation plastique. On comprend aisément que la valeur de la flèche est donnée en fonction des caractéristiques mécaniques de la matière et du profil de la lame 9, 10.In all cases, the wall 12 of each blade 9, 10 must be able to deform and reach an arrow of determined value without undergoing plastic deformation. It is easy to understand that the value of the deflection is given as a function of the mechanical characteristics of the material and of the profile of the blade 9, 10.
On remarque également que la matière utilisée pour les lames 9 et 10 empêche la formation et l'adhérence de glace lorsque les portes de manutention sont employées pour isoler des pièces dont les températures internes sont différentes.It is also noted that the material used for the blades 9 and 10 prevents the formation and adhesion of ice when the handling doors are used to isolate parts whose internal temperatures are different.
Par exemple, le matériau utilisé pour la fabrication des lames 9 et 10 appartient à la famille des polyéthylènes.For example, the material used for the manufacture of blades 9 and 10 belongs to the family of polyethylenes.
On constate que la distance entre les lames 9 et 10 disposées l'une en face de l'autre sur chaque montant 2, 3 peut varier pour présenter une glissière de guidage 11 plus ou moins large.It is noted that the distance between the blades 9 and 10 arranged one opposite the other on each upright 2, 3 can vary to present a more or less wide guide slide 11.
On note que lorsque que la distance entre les lames 9 et 10 est grande le dégondage des traverses horizontales de raidissement 7 et du rideau souple 5 de la glissière 11 lors d'un effort extérieur est aisé.It will be noted that when the distance between the blades 9 and 10 is large, the unhinging of the horizontal stiffening crosspieces 7 and of the flexible curtain 5 of the slide 11 during an external force is easy.
A contrario, plus la glissière 11 présente une petite distance entre ses lames 9 et 10, plus l'expulsion des traverses horizontales de raidissement 7 et du rideau souple 5 sera difficile lors d'un effort extérieur.Conversely, the more the slide 11 has a small distance between its blades 9 and 10, the more the expulsion of the horizontal stiffening crosspieces 7 and the flexible curtain 5 will be difficult during an external force.
II doit d'ailleurs être entendu que la description qui précède n'a été donnée qu'à titre d'exemple et quelle ne limite nullement le domaine de l'invention dont on ne sortirait pas en remplaçant les détails d'exécution décrits par tout autre équivalent. It should moreover be understood that the foregoing description has been given only by way of example and which in no way limits the field of the invention from which one would not depart by replacing the execution details described by any other equivalent.
