The internal profile 7 e comprises above and below the central groove 7 f and over the entire length of each half-shell 7 b , 7 c flat and parallel faces 7g.

La rainure centrale 7f de chaque demi coque 7b, 7c comporte un fond 7h disposé dans un plan vertical et parallèle à celui contenant les faces 7g bordant ladite rainure.The central groove 7f of each half shell 7b , 7c has a bottom 7h disposed in a vertical plane and parallel to that containing the faces 7g bordering said groove.

Le fond 7h de la rainure centrale 7f coopère sur toute sa longueur avec une bande adhésive 7i ou analogue permettant la fixation et la retenue de chaque demi coque 7b, 7c autour du profil tubulaire 7a.The bottom 7 h of the central groove 7 f cooperates along its length with an adhesive tape 7 i or the like for fixing and retaining each half shell 7 b , 7 c around the tubular profile 7 a .

La rainure centrale 7f de chaque demi coque 7b, 7c présente des dimensions internes qui sont complémentaires à celles externes du profil tubulaire 7a. Ainsi, la hauteur h de la rainure centrale 7f est légèrement supérieure à celle du coté 7j du profil tubulaire 7a, tandis que la profondeur p de la rainure centrale 7f est égale à la moitié de celle du coté 7k, disposé perpendiculairement au coté 7j, du profil tubulaire 7a.The central groove 7 f of each half shell 7 b, 7 c has internal dimensions that are complementary to those of the external tubular profile 7 has. Thus, the height h of the central groove 7 f is slightly greater than that of the next 7 days of the tubular profile 7a, while the depth p of the center groove 7 f is equal to half that of the side 7k disposed perpendicular to the side 7 j of the tubular profile 7 a .

Les premières et secondes demi coques 7b, 7c sont agencées autour du profil tubulaire 7a de manière que chaque coté 7j dudit profil tubulaire vient coopérer avec la bande adhésive 7i ou analogue prévue contre le fond 7h des rainures 7f.The first and second half-shells 7 b, 7 c are arranged around the tubular profile 7 is such that each side 7 j of said tubular profile cooperates with the tape 7 i or the like provided against the bottom 7 h of the grooves 7f.

Cet agencement permet l'assemblage des demi coques 7b, 7c sur et autour du profil tubulaire 7a afin de l'envelopper totalement sur toute sa longueur. Ainsi, le tambour modulaire 7 présente un profil externe cylindrique qui provient de l'association des profils externes 7d de chacune des demi coques 7b, 7c de sorte que ledit profil externe cylindrique puisse se déformer élastiquement sous une pression extérieure.This arrangement allows the assembly of the half shells 7 b, 7 c and around the tubular profile 7 has to wrap completely throughout its length. Thus, the modular drum 7 has a cylindrical outer profile which comes from the combination of the external profiles 7 d of each of the half-shells 7b , 7c so that said cylindrical outer profile can deform elastically under external pressure.

On a représenté en figures 4 et 5 le tambour modulaire 7 dont le profil tubulaire 7a est entièrement enveloppé par les premières et secondes demi coques 7b, 7c.We have shown in Figures 4 and 5 the modular drum 7, the tubular profile 7 has is fully enveloped by the first and second half-shells 7 b, 7 c.

On note que la coque 7m et par exemple l'une au moins des demi coques 7b, 7c comporte sur son profil externe 7d, en portion de cylindre, des moyens de fixation 20 qui permettent la mise en place et la retenue du tablier ou rideau souple 6, lorsque le porte de manutention 1 est, par exemple, à enroulement.Note that the shell 7 m and for example at least one of the half shells 7 b, 7 c has on its outer edge 7 d, cylinder portion, fixing means 20 which allow the introduction and retention of the flexible curtain or curtain 6, when the handling door 1 is, for example, winding.

Les moyens de fixation 20 sont disposés sur toute la longueur du tambour modulaire 7 et parallèlement à l'axe horizontal de ce dernier.The fixing means 20 are arranged along the entire length of the modular drum 7 and parallel to the horizontal axis of the latter.

Les moyens de fixation 20 peuvent être constitués par une bande 21 suffisamment large de type VELCRO assurant du fait de ses caractéristiques un accrochage et un décrochage du tablier ou rideau souple 6 sans détérioration du profil externe 7d de la coque 7m ou de la demi coque 7b, 7c correspondante.The fastening means 20 may be constituted by a sufficiently wide 21 band VELCRO type providing because of its characteristics hooking and unhooking of the flexible curtain or apron 6 without damaging the outer edge 7 of the hull 7 m or half shell 7b , 7c corresponding.

On a illustré en figures 6 à 8 une première variante du tambour modulaire 7 et plus particulièrement de la coque à profil cylindrique 7m enveloppant le profil tubulaire 7a.We have illustrated in Figures 6 to 8 a first variant of the modular drum 7 and more particularly of the cylindrical shell 7 m enveloping the tubular profile 7 a .

La coque 7m est réalisée en une seule partie souple et comporte en son milieu sur toute sa longueur un profil interne 7e aménagé suivant un alésage 7p dont le profil est complémentaire à celui externe du profil tubulaire 7a formant l'âme du tambour d'entraînement modulaire 7.The shell 7 m is made of a single flexible part and comprises in its middle along its entire length an internal profile 7 e arranged in a bore 7 p whose profile is complementary to that external of the tubular profile 7 has forming the core of the drum modular drive 7.

L'alésage 7p est prévu pour coopérer avec le profil tubulaire 7a afin que ce dernier soit totalement enveloppé par la coque 7m pour présenter un profil externe cylindrique et déformable élastiquement lors d'une pression extérieure.The bore 7 p is provided to cooperate with the tubular profile 7 is so that it is fully enveloped by the shell 7 m to present a cylindrical and elastically deformable outer profile at an external pressure.

On a représenté en figures 9 et 10 une seconde variante du tambour modulaire 7 et plus particulièrement de la coque à profil cylindrique 7m enveloppant le profil tubulaire 7a.We have shown in Figures 9 and 10 a second variant of the modular drum 7 and more particularly of the shell with a cylindrical profile 7 m enveloping the tubular profile 7 a .

La coque 7m est réalisée en une seule partie souple et comporte, en son milieu sur toute sa longueur, un alésage 7p de profil complémentaire à celui externe du profil tubulaire 7a formant l'âme du tambour modulaire 7.The hull 7 m is made of a single flexible portion and has, in its middle along its length, a profile complementary to 7 p bore than the outside of the tubular profile 7 has forming the core of the modular drum 7.

La coque 7m comporte sur toute sa longueur et à partir de son profil externe cylindrique une fente 7q débouchant à l'intérieur du profil interne 7e aménagé suivant un alésage 7p recevant le profil tubulaire 7a.The shell 7 m comprises along its entire length and from its cylindrical outer profile a slot 7 q opening inside the internal profile 7 e arranged in a bore 7 p receiving the tubular profile 7 a .

La fente 7q permet de réaliser un accès en écartant les deux bords de cette dernière pour permettre l'introduction du profil tubulaire 7a à l'intérieur de l'alésage 7p.The slot 7 q allows access by removing the two edges of the latter to allow the introduction of the tubular profile 7 has inside the bore 7 p .

La fente 7q est ensuite fermée sur toute la longueur de la coque 7m par l'intermédiaire par exemple d'une bande adhésive ou analogue.The slot 7 q is then closed over the entire length of the shell 7 m through for example an adhesive tape or the like.

On note que le tambour d'entraînement modulaire 7 suivant la présente invention est léger et facilement ajustable à la longueur souhaitée en fonction des caractéristiques de la porte de manutention 1.Note that the modular drive drum 7 according to the present invention is lightweight and easily adjustable to the desired length depending on the characteristics of the handling door 1.

On constate que le tambour d'entraînement modulaire 7 suivant la présente invention permet un enroulement et un déroulement silencieux du tablier ou rideau souple 6 ou des sangles de traction 8 du fait de la déformation élastique de la coque 7m lors d'une pression extérieure. Cette déformation élastique de la coque 7m permet d'absorber les chocs et la résonance des traverses horizontales 10, 13 du tablier ou rideau souple 6.It is found that the modular drive drum 7 according to the present invention allows a winding and a silent running of the flexible curtain or curtain 6 or traction straps 8 due to the elastic deformation of the shell 7 m during an external pressure . This elastic deformation of the shell 7 m makes it possible to absorb the shocks and the resonance of the horizontal crosspieces 10, 13 of the flexible curtain or curtain 6.

La coque 7m peut être réalisée dans divers matériaux élastiques hydrophobes comme par exemple en mousse alvéolaire ou réticulée. La coque 7m peut être également réalisée dans un matériau élastique comme par exemple du polyéthylène extrudé.The shell 7 m can be made in various hydrophobic elastic materials such as cellular foam or reticulated. The shell 7 m can also be made of an elastic material such as extruded polyethylene.

On remarque le tambour d'entraînement modulaire 7 suivant la présente invention ne comporte pas de liaison définitive comme par soudure, par vis, par clavetage, reliant le profil tubulaire 7a aux arbres 18, 19 et empêchant toute modification de ce dernier en fonction des caractéristiques de la porte de manutention 1.Note the modular drive drum 7 according to the present invention does not comprise a final connection as by welding, with screws, by keying, connecting the tubular profile 7 has the shafts 18, 19 and preventing any modification of the latter based on characteristics of the handling door 1.

On note que la coque 7m peut être facilement démontable du profil tubulaire 7a permettant par exemple son changement si une usure venait à se produire sans être obligé de démonter intégralement le tambour d'entraînement modulaire 7.7 m can be easily removable from the tubular profile is noted that the shell 7 has for example its change if wear were to occur without having to completely disassemble the modular driving drum 7.

Egalement, la coque 7m peut être changée afin d'augmenter ou de réduire son diamètre externe cylindrique pour que ce dernier soit parfaitement adapté aux conditions de fonctionnement de la porte de manutention 1 si les caractéristiques de cette dernière venaient à être modifiées.Also, the shell 7 m can be changed to increase or reduce its cylindrical outer diameter so that the latter is perfectly adapted to the operating conditions of the handling door 1 if the characteristics of the latter had to be modified.

On note que la structure du tambour d'entraînement modulaire 7 permet de garantir un diamètre externe cylindrique semblable à ceux couramment utilisé du fait de la section et des dimensions du profil tubulaire 7a formant l'âme et permettant de fixer une coque 7m d'épaisseur suffisante pour obtenir le diamètre définitif du tambour.It is noted that the modular structure of the driving drum 7 ensures a cylindrical outer diameter similar to those commonly used because of the section and the dimensions of the tubular profile 7 has forming the core and for securing a shell 7m of sufficient thickness to obtain the final diameter of the drum.

On constate que la structure du tambour d'entraînement modulaire 7 permet de réduire le poids dudit tambour du fait de la section et des dimensions du profil tubulaire 7a formant l'âme et donc de prévoir un moteur d'entraînement de puissance plus faible permettant d'engendrer des économies d'énergie.It is noted that the modular structure of the driving drum 7 to reduce the weight of said drum due to the section and the dimensions of the tubular profile 7 has forming the core and therefore to provide a smaller power drive motor for to generate energy savings.

Il doit d'ailleurs être entendu que la description qui précède n'a été donnée qu'a 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 must also be understood that the foregoing description has been given by way of example only and that it in no way limits the scope of the invention which could not be overcome by replacing the execution details described. by all other equivalents.
