Description

Le domaine de l'invention est celui du levage d'objets qui demandent un soin particulier pour ne pas en abîmer la surface.The field of the invention is that of lifting objects that require special care not to damage the surface.

La présente invention concerne un dispositif permettant la protection de la surface d'un objet contre les effets des sangles au cours des manoeuvres de levage, particulièrement la protection des peintures de coques de bateaux. La présente invention concerne aussi un procédé de réalisation du dispositif concerné.The present invention relates to a device for protecting the surface of an object against the effects of straps during lifting maneuvers, particularly the protection of boat hull paints. The present invention also relates to a method of producing the device concerned.

Lorsque les bateaux viennent d'être repeints, lors de la mise à l'eau, les peintures sont souvent rayées par les sangles de l'engin de levage. On observe des altérations de l'ordre de 80%. Certains protègent la coque en introduisant des morceaux de carton, de moquette ou des sacs en plastique entre la surface à protéger et la ou les sangles de levage mais ces accessoires de fortune sont très difficiles à maintenir en place lorsque les sangles de l'engin sont prêtes pour le levage.When the boats have just been repainted, when they are launched, the paint is often scratched by the straps of the hoist. There are alterations of the order of 80%. Some protect the hull by introducing pieces of cardboard, carpet or plastic bags between the surface to be protected and the lifting strap or straps but these makeshift accessories are very difficult to hold in place when the straps of the machine are ready for lifting.

Le document FR2452459 divulgue une gaine pour élingue de levage de charge qui se présente sous forme de sangle plate. Les câbles de l'élingue étant à demeure dans la gaine de protection, un problème se pose sur la connaissance de leur état car toute rupture résultant d'une détérioration de l'élingue serait préjudiciable au levage de la charge. La configuration proposée nécessite des fenêtres de visibilité. Les coûts engendrés par la complexité de réalisation, ne facilitent pas une large diffusion de ce type de gaine sur tout lieu de levage, par exemple dans des régions moins favorisées. D'autre part, les câbles y sont bien de préférence logés avec jeu dans les ouvertures de sorte que la gaine entière peut se déplacer dans certaines limites le long de l'élingue. Ceci ne suffit pas nécessairement à garantir une absence totale de frottement sur la l'objet levé par la gaine lors de la mise en tension des câbles. De tels frottements peuvent être préjudiciables à la peinture des coques de bateaux.The document FR2452459 discloses a load lifting sling sheath which is in the form of a flat strap. The cables of the sling being permanently in the protective sheath, a problem arises on the knowledge of their state because any break resulting from a deterioration of the sling would be detrimental to the lifting of the load. The proposed configuration requires visibility windows. The costs generated by the complexity of implementation, do not facilitate wide distribution of this type of sheath on any place of lifting, for example in less favored regions. On the other hand, the cables are preferably accommodated with clearance in the openings so that the entire sheath can move within certain limits along the sling. This is not necessarily sufficient to guarantee a total absence of friction on the object lifted by the sheath when tensioning the cables. Such friction can be detrimental to the painting of boat hulls.

Le document FR2891524 décrit un fourreau dans lequel peuvent glisser les sangles de levage de façon à ne pas endommager la peinture. Il est possible de contrôler si besoin l'état des sangles en les retirant du fourreau ou avant de les y introduire. Dans un port ne disposant que d'élingues non équipées pour assurer une bonne protection de la peinture de la coque des bateaux, on peut alors envisager de faire passer l'élingue dans le fourreau mais ceci nécessite un minimum de manipulations.The document FR2891524 describes a sleeve in which the lifting straps can slide so as not to damage the paint. It is possible to control if necessary the condition of the straps by removing them from the sheath or before introducing them. In a port having only slings not equipped to ensure good protection of the painting of the hull of boats, it is then possible to consider passing the sling in the sheath but this requires a minimum of manipulation.

Pour remédier aux inconvénients de l'état connu de la technique, un objet de l'invention est un dispositif pour soulever un objet en en protégeant la surface. Le dispositif est remarquable en ce qu'il comprend une première bande prévue pour être en contact avec la surface de l'objet, une deuxième bande prévue pour être en contact avec des sangles de levage et une couche de matériau lubrifiant disposée entre la première et la deuxième bande reliées entre elles à chacune de leurs extrémités.To overcome the disadvantages of the state of the art, an object of the invention is a device for lifting an object by protecting the surface. The device is notable in that it comprises a first band intended to be in contact with the surface of the object, a second band intended to be in contact with lifting straps and a layer of lubricant material placed between the first and the the second band connected together at each of their ends.

On peut utiliser un matériau lubrifiant liquide. Toutefois particulièrement à l'égard de la peinture fraîche sur la coque des bateaux, il est nécessaire de prendre garde aux salissures que pourraient provoquer par exemple des fuites de liquide. On connaît aussi des matériaux lubrifiants solides tels que le polytétrafluoréthylène ou le graphite en couches minces superposées qui présentent l'avantage de ne pas fuir. Ces matériaux présentent cependant certains inconvénients en termes de coût, voire de fragilité.A liquid lubricating material can be used. However particularly with regard to the fresh paint on the hull of the boats, it is necessary to take care of the stains which could cause for example leaks of liquid. Solid lubricant materials such as polytetrafluoroethylene or graphite in superimposed thin layers are also known which have the advantage of not escaping. These materials, however, have certain disadvantages in terms of cost, or even fragility.

De préférence, le matériau lubrifiant de la couche est de la paraffine qui apporte les avantages d'un lubrifiant solide avec un bon rapport qualité coût.Preferably, the lubricating material of the diaper is paraffin which provides the benefits of a solid lubricant with good cost-effectiveness.

Des moyens d'attache fixés aux extrémités des deux bandes reliées entre elles, tels que par exemple des anneaux, permettent d'utiliser le dispositif comme une sangle à accrocher au palan d'une grue. Ceci peut nécessiter des manipulations supplémentaires que le grutier n'est pas nécessairement préparé à faire.Fastening means attached to the ends of the two interconnected strips, such as, for example, rings, allow to use the device as a strap to hang on a hoist crane. This may require additional manipulations that the crane operator is not necessarily prepared to do.

Avantageusement, des moyens d'attache fixés aux extrémités des deux bandes reliées entre elles, tels que par exemple des rubans sur l'une et des oeillets sur l'autre, permettent après avoir fait passer les bandes sou l'objet de les attacher entre elles au dessus de façon à le protéger à la manière d'une enveloppe sur laquelle il suffit de mettre en contact la sangle de levage proprement dite de la grue. On indique que le terme sangle de levage est ici à prendre dans son acception la plus large, à savoir tant une sangle plate à proprement parler qu'une élingue, un ou plusieurs câbles.Advantageously, fastening means attached to the ends of the two interconnected strips, such as for example ribbons on one and eyelets on the other, allow after passing the strips p object to attach them between they above so as to protect it in the manner of an envelope on which it is sufficient to bring into contact the lifting strap itself of the crane. It is indicated that the term lifting strap is here to be taken in its broadest sense, namely both a flat strap strictly speaking a sling, one or more cables.

Plus particulièrement, un ensemble d'un ou plusieurs rubans à chacune des extrémités permet d'attacher les bandes sur une partie supérieure de l'objet sans avoir à en faire un tour complet, ce qui est appréciable pour un objet volumineux tel qu'un bateau où il suffit alors de faire passer les bandes sous la coque et d'attacher les extrémités au bastingage. On indique ici encore que le terme ruban est à prendre dans son acception la plus large, à savoir tant des rubans plats au sens propre de nature bien entendu suffisamment résistante que des cordelettes en nylon ou autres cordages de marines. Un effet proche peut être obtenu en disposant des oeillets aux deux extrémités et en y faisant passer des lacets accrochés par ailleurs au bastingage.More particularly, a set of one or more ribbons at each end makes it possible to attach the strips to an upper part of the object without having to make a complete turn, which is appreciable for a bulky object such as a boat where it is sufficient to pass the strips under the hull and attach the ends to the rail. It is again indicated here that the term ribbon is to be taken in its broadest sense, namely flat ribbons in the proper sense of nature of course sufficiently resistant as nylon cords or other marine ropes. A close effect can be obtained by arranging eyelets at both ends and by passing laces hung elsewhere on the rail.

Un autre objet de l'invention est un procédé de fabrication d'un dispositif pour soulever un objet en en protégeant la surface. Dans ce procédé, une première bande prévue pour être en contact avec la surface de l'objet est superposée sur une deuxième bande prévue pour contribuer aux fonctions de levage, la première et la deuxième bande sont reliées entre elles à chacune de leurs extrémités et une couche de matériau lubrifiant est injectée entre les deux bandes.Another object of the invention is a method of manufacturing a device for lifting an object by protecting the surface. In this method, a first band intended to be in contact with the surface of the object is superimposed on a second band designed to contribute to the lifting functions, the first and the second band are interconnected with each other. their ends and a layer of lubricant material is injected between the two strips.

Préférentiellement, le matériau lubrifiant de la couche intermédiaire est de la paraffine.Preferably, the lubricating material of the intermediate layer is paraffin.

Avantageusement, on soude sur les bords de leurs longueurs les deux bandes entres elles qui comprennent chacune un film plastique, ou on utilise un tube de film plastic extrudé qui est ensuite aplati afin d'avoir deux épaisseurs de film l'une sur l'autre. Ceci est particulièrement utile au propriétaire d'un bateau qui peut emmener alors le dispositif avec lui de façon à pouvoir l'utiliser en tout lieu où il déciderait de faire repeindre son bateau sans avoir à craindre que le matériau lubrifiant ne s'échappe du dispositif. Il est aisé de plier ou mieux encore d'enrouler des bandes sous forme de film et une constitution en matière plastique permet un soudage propre et souple.Advantageously, are welded on the edges of their lengths the two strips between them which each comprise a plastic film, or using an extruded plastic film tube which is then flattened to have two film thicknesses one on the other . This is particularly useful for the owner of a boat who can then take the device with him so that he can use it wherever he decides to repaint his boat without having to fear that the lubricant material escapes from the device. . It is easy to fold or even better to wrap strips in the form of film and a plastic constitution allows a clean and flexible welding.

Un autre objet encore de l'invention est un procédé de levage d'un objet en en protégeant la surface. Préalablement au levage de l'objet, on met une première bande en contact avec la surface de l'objet, on superpose une deuxième bande sur la première bande pour contribuer aux fonctions de levage et on dispose une couche de matériau lubrifiant entre la première et la deuxième bande que l'on relie entre elles à chacune de leurs extrémités.Still another object of the invention is a method of lifting an object by protecting the surface thereof. Prior to lifting the object, a first strip is placed in contact with the surface of the object, a second strip is superimposed on the first strip to contribute to the lifting functions and a layer of lubricant material is placed between the first and the second strip. the second band that is connected together at each of their ends.

L'invention sera mieux comprise, et d'autres buts, caractéristiques, détails et avantages de celle-ci apparaîtront plus clairement dans la description explicative qui va suivre faite en référence aux dessins schématiques annexés donnés uniquement à titre d'exemple, illustrant un mode préféré de réalisation de l'invention et dans lesquels :

  • la figure 1 montre un objet muni du dispositif selon l'invention ;
  • la figure 2 est une vue de dessus du dispositif selon l'invention ; et
  • la figure 3 est une vue en coupe transversale du dispositif selon l'invention.
The invention will be better understood, and other objects, features, details and advantages thereof will appear more clearly in the explanatory description which will follow made with reference to the accompanying schematic drawings given solely by way of example, illustrating a mode preferred embodiment of the invention and in which:
  • the figure 1 shows an object provided with the device according to the invention;
  • the figure 2 is a top view of the device according to the invention; and
  • the figure 3 is a cross-sectional view of the device according to the invention.

En référence à la figure 1, on explique un procédé de levage dans lequel on a fait passer des bandes 1, 2 sous une coque 6 de bateau 10 qui constitue un objet que l'on souhaite soulever. On a attaché chacune des extrémités 3 au bastingage 7 du bateau 10 qui constitue une partie supérieure de l'objet à soulever.With reference to the figure 1 a lifting method is explained in which strips 1, 2 have been passed under a boat hull 6 which constitutes an object which it is desired to lift. Each of the ends 3 has been attached to the rail 7 of the boat 10 which constitutes an upper part of the object to be lifted.

On a obtenu la configuration présentée après avoir mis une première bande 1 en contact avec la surface de l'objet, avoir superposé une deuxième bande 2 sur la première bande pour contribuer à des fonctions de levage, avoir disposé une couche 5 de paraffine qui constitue un matériau lubrifiant solide entre la première et la deuxième bande et avoir relié entre elles les bandes 1 et 2 à chacune de leurs extrémités 3.The configuration presented was obtained after putting a first strip 1 in contact with the surface of the object, superimposing a second strip 2 on the first strip to contribute to lifting functions, having a paraffin layer 5 which constitutes a solid lubricant material between the first and second strips and interconnecting the strips 1 and 2 at each of their ends 3.

La couche 5 n'est pas visible sur la figure 1 car elle est masquée par la bande 2.Layer 5 is not visible on the figure 1 because it is hidden by the band 2.

L'ordre des actions énumérées ci-dessus peut varier au gré de celui qui met en oeuvre le procédé. On conçoit bien que l'ordre dans lequel les actions sont énumérées n'est pas forcément le plus pratique mais il est possible avec la variante d'avoir disposé la couche de paraffine entre les bandes 1 et 2 avant ou après les avoir reliées entre elles. Elle peuvent aussi se résumées aux actions simplifiées de faire passer sous la coque du bateau un dispositif complet tel qu'expliqué ci-après en référence aux figures 2 et 3 puis d'en attacher les extrémités au bastingage du bateau.The order of the actions listed above may vary according to whoever implements the process. Although the order in which the actions are enumerated is not necessarily the most practical, it is possible with the variant to have the paraffin layer disposed between the bands 1 and 2 before or after connecting them together. . It can also be summed up in simplified actions to pass under the hull of the boat a complete device as explained below with reference to Figures 2 and 3 then attach the ends to the rail of the boat.

Les moyens d'attache au bastingage ici représenté sont constitués par trois rubans 4 d'un mètre environ chacun.The attachment means to the rail here shown are constituted by three ribbons 4 of about one meter each.

Les étapes précédemment décrites permettent dans une étape suivante, de mettre une sangle de levage en contact avec la deuxième bande de façon à soulever le bateau sans causer de dommage à sa surface comme expliqué à présent.The steps previously described allow in a next step, to put a lifting strap in contact with the second band so as to lift the boat without causing damage to its surface as explained now.

Dans le cas illustré par la figure 1, la bande 1 est par exemple un premier film plastique et la bande 2 est par exemple un deuxième film plastique.In the case illustrated by the figure 1 , the strip 1 is for example a first plastic film and the strip 2 is for example a second plastic film.

Le premier film en contact directe avec la coque du bateau, préserve la peinture sur la surface de la coque. Grâce à la présence de paraffine injectée entre les deux films, le second film glisse sur le premier lors de la tension de la sangle de levage de sorte que le film en contact de la coque ne bouge pas et par conséquent ne provoque pas de frottement sur la peinture.The first film in direct contact with the hull of the boat, preserves the paint on the surface of the hull. Thanks to the presence of paraffin injected between the two films, the second film slides on the first during the tension of the lifting strap so that the film in contact with the shell does not move and therefore does not cause friction on the painting.

En référence à la figure 2, le dispositif mentionné ci-dessus comprend une première bande 1 prévue pour être en contact avec la surface de l'objet, par exemple la coque de bateau représentée en figure 1. La bande 1 comprend un film plastique d'épaisseur adaptée à la taille et à l'état de surface de l'objet à soulever. A titre illustratif, on peut citer deux modèles, l'un en film de 30 microns d'épaisseur pour les bateaux n'ayant pas de partie saillante, l'autre en film de 60 microns d'épaisseur pour les bateaux plus lourds et ayant des parties saillantes.With reference to the figure 2 , the device mentioned above comprises a first band 1 intended to be in contact with the surface of the object, for example the boat hull represented in figure 1 . The strip 1 comprises a plastic film of thickness adapted to the size and the surface condition of the object to be lifted. By way of illustration, two models can be mentioned, one in 30 micron thick film for boats with no protruding part, the other in 60 micron thick film for heavier boats and having protruding parts.

Aux extrémités 3 de la bande 1, on observe des bretelles d'attache telles que trois rubans 4 d'un mètre environ, agencés pour permettre la fixation de la bande sur le bastingage du bateau. La bande 1 est enduite sur la face opposée à celle prévue pour être en contact avec la surface à protéger, d'un matériau lubrifiant de préférence solide et non salissant tel que de la paraffine.At the ends 3 of the band 1, there are attachment straps such as three ribbons 4 of about one meter, arranged to allow the attachment of the band on the rail of the boat. The strip 1 is coated on the face opposite to that intended to be in contact with the surface to be protected, a lubricating material preferably solid and non-messy such as paraffin.

La figure 3 est une vue en coupe selon la ligne a-a de la figure 2. Une deuxième bande 2 est prévue pour contribuer aux fonctions de levage, par exemple pour être soumise au contact d'une sangle ou autre élingue extérieure.The figure 3 is a sectional view along the line aa of the figure 2 . A second band 2 is provided to contribute to the lifting functions, for example to be subjected to contact with a strap or other external sling.

La deuxième bande 2 glisse sur la première bande 1 grâce à une couche 5 de paraffine injectée entre les deux bandes. La paraffine constitue le matériau lubrifiant disposé sur la bande 1, mentionné ci-dessus. La bande 2 est reliée à la bande 1 à chaque extrémité 3 vue sur la figure 1 et/ou sur les bords de leur longueur par soudure comme représenté sur la figure 3.The second band 2 slides on the first band 1 thanks to a layer 5 of paraffin injected between the two bands. Paraffin is the lubricating material arranged on the strip 1, mentioned above. The band 2 is connected to the band 1 at each end 3 seen on the figure 1 and / or at the edges of their length by welding as shown on the figure 3 .

Le dispositif qui vient d'être décrit est fabriqué par un procédé dans lequel :

  • une première bande 1 prévue pour être en contact avec la surface de l'objet est superposée sur une deuxième bande 2 prévue pour contribuer aux fonctions de levage ;
  • la première et la deuxième bande sont reliées entre elles à chacune de leurs extrémités ;
  • une couche 5 de matériau lubrifiant, de préférence de la paraffine, est injectée entre les deux bandes ;
  • on soude sur les bords de leurs longueurs les deux bandes entres elles qui comprennent chacune un film plastique ;
  • on fixe à une extrémité qui relient la première et la deuxième bande entre elles, des moyens d'attache à un élément extérieur à ladite extrémité.
The device which has just been described is manufactured by a method in which:
  • a first strip 1 intended to be in contact with the surface of the object is superimposed on a second strip 2 provided to contribute to the lifting functions;
  • the first and second strips are interconnected at each of their ends;
  • a layer 5 of lubricating material, preferably paraffin, is injected between the two strips;
  • the two strips are welded on the edges of their lengths, each of which comprises a plastic film;
  • at one end, which connect the first and the second strip between them, fastening means to an element external to said end.

Selon une variante particulièrement avantageuse, le procédé de fabrication est simplifié en ce qu'il met en oeuvre des étapes dans lesquelles :

  • un tube de polyéthylène extrudé est aplati de façon à obtenir deux épaisseurs superposées dont l'une constitue une première bande 1 prévue pour être en contact avec la surface de l'objet et dont l'autre constitue une deuxième bande 2 prévue pour suivre un dispositif de levage ;
  • une couche 5 de matériau lubrifiant, de préférence de la paraffine, est injectée entre les deux bandes ;
  • la première et la deuxième bande sont reliées entre elles à chacune de leurs extrémités ;
  • on fixe à une extrémité qui relient la première et la deuxième bande entre elles, des moyens d'attache à un élément extérieur à ladite extrémité.
According to a particularly advantageous variant, the manufacturing process is simplified in that it implements steps in which:
  • an extruded polyethylene tube is flattened so as to obtain two superimposed thicknesses, one of which constitutes a first strip 1 intended to be in contact with the surface of the object and the other of which constitutes a second strip 2 intended to follow a device lifting;
  • a layer 5 of lubricating material, preferably paraffin, is injected between the two strips;
  • the first and second strips are interconnected at each of their ends;
  • at one end, which connect the first and the second strip between them, fastening means to an element external to said end.
