Abstract
Description
La présente invention a trait à un nouveau profilé d'armature métallique qui est disposée à l'intérieur des fourreaux horizontaux du tablier souple d'une porte de manutention. The present invention relates to a new metal reinforcing profile which is arranged inside the horizontal sleeves of the flexible deck of a handling door.
On connaît des portes de manutention comprenant un tablier souple enroulable autour d'un arbre horizontal qui est entraîné en rotation par l'intermédiaire d'un moto-réducteur. Handling doors are known comprising a flexible apron which can be wound around a horizontal shaft which is rotated by means of a gear motor.
Le tablier souple comporte une série de fourreaux horizontaux dans lesquels sont introduits des tubes à section circulaire. Les tubes dépassent de chaque côté du tablier souple pour que leurs extrémités libres coopèrent avec des glissières prévues à l'intérieur des montants verticaux de manière à guider le tablier souple lors de ses déplacements. The flexible apron comprises a series of horizontal sleeves into which tubes of circular section are introduced. The tubes protrude on each side of the flexible apron so that their free ends cooperate with slides provided inside the vertical uprights so as to guide the flexible apron during its movements.
Lors de l'enroulement du tablier souple autour de L'arbre horizontal, on remarque que le volume du tablier enroulé augmente considérablement du fait de l'empilement des tubes cylindriques les uns sur les autres. En outre, Les tubes à section circulaire se heurtent lors de l'enroulement du tablier souple autour de l'arbre horizontal, augmentant le bruit de fonctionnement de la porte de manutention. When winding the flexible apron around the horizontal shaft, it is noted that the volume of the wound apron increases considerably due to the stacking of the cylindrical tubes on top of each other. In addition, the circular section tubes collide when the flexible apron is wound around the horizontal shaft, increasing the operating noise of the handling door.
C'est à ces inconvénients qu'entend particulièrement remédier La présente invention. It is to these drawbacks that the present invention particularly intends to remedy.
L'armature métallique suivant la présente invention présente un profil extérieur en forme de huit. Le profil extérieur de l'armature métallique est obtenu à partir de l'écrasement d'un tube cylindrique à section circulaire au moyen d'un dispositif de pression. The metal frame according to the present invention has an eight-shaped outer profile. The external profile of the metal frame is obtained from the crushing of a cylindrical tube with circular section by means of a pressure device.
L'armature en forme de huit peut être réalisée en acier ou en aluminium en matière plastique et plus particulièrement en polyester armé. The eight-shaped frame can be made of steel or of plastic aluminum and more particularly of reinforced polyester.
Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer
Fig. 1 est une vue en perspective partielle illustrant une porte de manutention comprenant les armatures suivant la présente invention.The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is capable of providing.
Fig. 1 is a partial perspective view illustrating a handling door comprising the frames according to the present invention.
Fig. 2 et 3 sont des vues schématiques montrant l'obtention de l'armature en forme de huit à partir de l'écrasement d'un tube métallique. Fig. 2 and 3 are schematic views showing the obtaining of the eight-shaped reinforcement from the crushing of a metal tube.
Fig. 4 est une coupe représentant un tube à l'intérieur d'un fourreau horizontal appartenant à une porte de manutention de L'art antérieur. Fig. 4 is a section showing a tube inside a horizontal sleeve belonging to a handling door of the prior art.
Fig. 5 est une vue semblable à celle de fig. 4, mais illustrant l'armature suivant la présente invention à l'intérieur d'un fourreau horizontal. Fig. 5 is a view similar to that of FIG. 4, but illustrating the frame according to the present invention inside a horizontal sheath.
On a représenté en fig. 1 une porte de manutention 1 comportant un tablier souple 2 enroulable autour d'un arbre horizontal 3 qui est entrainé en rotation par l'intermédiaire d'un moto-réducteur 3a. There is shown in fig. 1 a handling door 1 comprising a flexible apron 2 which can be wound around a horizontal shaft 3 which is rotated by means of a geared motor 3a.
La porte 1 est constituée de montants latéraux la disposés de part et d'autre du tablier souple 2. The door 1 is made up of lateral uprights 1a arranged on either side of the flexible apron 2.
Chaque montant la comprend une glissière lb dans laquelle coulis- sent les extrémités libres des armatures 2a et la barre de seuil 2b de la porte de manutention 1. Each upright la comprises a slide 1b in which the free ends of the frames 2a and the threshold bar 2b of the handling door 1 slide.
Chaque armature 2a est introduite à l'intérieur d'un fourreau horizontal 2c prévu dans le tablier souple 2. Each frame 2a is introduced inside a horizontal sheath 2c provided in the flexible deck 2.
Les fourreaux 2c sont prévus parallèles les uns aux autres et comportent chacun des ouvertures non référencées pour la mise en place des armatures 2a et de la barre de seuil 2b. The sleeves 2c are provided parallel to each other and each have openings not referenced for the installation of the frames 2a and the threshold bar 2b.
Chaque extrémité des armatures 2a comporte un talon 2g souple et élastique qui permet d'une part le coulissement desdites armatures à
L'intérieur des glissières lb et d'autre part le dégondage des armatures indépendamment les unes des autres lors d'un choc latéral sur le tablier souple 2 de la porte de manutention 1.Each end of the frames 2a has a flexible and elastic heel 2g which allows on the one hand the sliding of said frames to
The interior of the rails 1b and on the other hand the unfolding of the reinforcements independently of one another during a lateral impact on the flexible deck 2 of the handling door 1.
En fig. 2 et 3, on a représenté un dispositif de pression 4 permettant d'obtenir le profil particulier de chaque armature 2a. En effet, les armatures 2a sont obtenues à partir d'un tube métallique 2'a qui est écrasé par l'intermédiaire de galets opposés 4a et 4b. Le tube 2'a présente un profil cylindrique à section ciculaire qui est écrasé sur toute sa longueur par les galets 4a, 4b de forme complémentaire pour obtenir une armature 2a dont le contour extérieur est sensiblement en forme de huit (fig. 3). On constate, après écrasement, que des rainures opposées longitudinales 2e et 2f séparent L'armature 2a en deux espaces distincts 29 et 2t de volumes identiques.Les rainures opposées 2e et 2f sont conformées d'une part au milieu de l'armature 2a et d'autre part pour être en contact l'une contre l'autre afin que les espaces 29 et 2h ne puissent communiquer. De plus, l'armature 2a présente un profil totalement symétrique par rapport à ses axes principaux. In fig. 2 and 3, there is shown a pressure device 4 making it possible to obtain the particular profile of each frame 2a. Indeed, the frames 2a are obtained from a metal tube 2'a which is crushed by means of opposite rollers 4a and 4b. The tube 2'a has a cylindrical profile with a cicular section which is crushed over its entire length by the rollers 4a, 4b of complementary shape to obtain a frame 2a whose outer contour is substantially in the shape of an eight (fig. 3). It can be seen, after crushing, that opposite longitudinal grooves 2e and 2f separate the frame 2a into two distinct spaces 29 and 2t of identical volumes. The opposite grooves 2e and 2f are shaped on the one hand in the middle of the frame 2a and on the other hand to be in contact with each other so that spaces 29 and 2h cannot communicate. In addition, the frame 2a has a completely symmetrical profile with respect to its main axes.
On note que le profil en forme de huit de l'armature 2a permet à cette dernière de réduire considérablement son encombrement à l'inte- rieur du fourreau 2c du tablier souple 2 par rappport à un tube cylindrique 5 à section circulaire couramment utilisé dans l'art antérieur (fig. 4 et 5). La faible épaisseur des armatures 2a permet, lors de l'enroulement du tablier souple 2 autour de l'arbre horizontal 3, de réduire l'épaisseur d'encombrement lorsque la porte de manutention 1 est ouverte. It is noted that the eight-shaped profile of the frame 2a allows the latter to considerably reduce its size inside the sheath 2c of the flexible deck 2 by comparison with a cylindrical tube 5 with circular section commonly used in l prior art (figs. 4 and 5). The small thickness of the frames 2a allows, when winding the flexible deck 2 around the horizontal shaft 3, to reduce the overall thickness when the handling door 1 is open.
On remarque également que le profil en forme de huit de chaque armature 2a intervient sur la diminution de la sonorité lors du fonctionnement de la porte de manutention 1. It is also noted that the eight-shaped profile of each frame 2a acts on the reduction of the sound during the operation of the handling door 1.
Il est évident que le profil de l'armature 2a peut être asymétrique sans pour cela changer le but de l'invention. It is obvious that the profile of the frame 2a can be asymmetrical without changing the object of the invention.
En effet, les rainures 2e et 2 peuvent être décalées latéralement par rapport au milieu de l'armature 2a pour obtenir deux espaces distincts de volumes différents. Indeed, the grooves 2e and 2 can be offset laterally relative to the middle of the frame 2a to obtain two separate spaces of different volumes.
L'armature 2a peut être réalisée en matière plastique et plus particulièrement en polyester armé. On note que les rainures 2e et 2f peuvent être écartées l'une de L'autre afin que les espaces 29 et 2h puissent communiquer, sans changer la forme extérieure de l'armature 2a. The frame 2a can be made of plastic and more particularly of reinforced polyester. It is noted that the grooves 2e and 2f can be separated from one another so that the spaces 29 and 2h can communicate, without changing the external shape of the frame 2a.
L'armature 2a peut présenter un profil intérieur identique à celui extérieur. The frame 2a may have an interior profile identical to that of the exterior.
il doit d'ailleurs être entendu que la description qui précède n'a été donnée qu'à titre d'exemple et qu'elle ne limite nullement le domaine de L'invention dont on ne sortirait pas en remplaçant les détails d'exécution décrits par tous autres équivalents. it should moreover be understood that the above description has been given only by way of example and that it in no way limits the field of the invention from which one would not depart by replacing the execution details described by all other equivalents.
