Abstract

L'invention concerne le levage de charges ou l'arrimage d'objets. C'est un accessoire permettant de relier temporairement deux extrémités de sangle, ou une extrémité de sangle à un autre dispositif, conçu de telle façon qu'aucune partie de cet accessoire ne déborde des faces externes utiles des sangles qu'il relie et qu'ainsi il ne risque pas de détériorer les objets manutentionnés ainsi que ceux d'une manière plus générale avec lesquels les sangles pourraient entrer en contact. L'invention est consitutée d'une pièce ayant la forme générale d'un "U" aux branches très allongées (1) recevant les extrémités de sangles en forme de boucles et d'un système manoeuvrable aisément à main nue, s'adaptant aux extrémités des branches, destiné à éviter le dégagement des extrémités de sangles, l'écartement des branches sous charges, et doté d'un dispositif de sécurité (2) évitant le dégagement de ce système des branches du "U". L'invention s'applique au levage et à l'arrimage d'objets fragiles, par exemple, à la manutention à terre des bateaux de plaisance.The invention relates to lifting loads or securing objects. It is an accessory making it possible to temporarily connect two ends of the strap, or one end of the strap to another device, designed in such a way that no part of this accessory projects beyond the useful external faces of the straps that it connects and that thus there is no risk of damaging the objects handled as well as those more generally with which the straps could come into contact. The invention consists of a part having the general shape of a "U" with very elongated branches (1) receiving the ends of straps in the form of loops and of an easily maneuverable system with bare hands, adapting to ends of the branches, intended to avoid the release of the ends of the straps, the separation of the branches under load, and provided with a safety device (2) preventing the release of this system from the branches of the "U". The invention applies to the lifting and stowage of fragile objects, for example, the handling on land of pleasure boats.

Description

" Epingle de jonction extra-plate pour sangles." "Extra-flat connecting pin for straps."
La présente invention concerne les accessoires de sangles d'arrimage et plus particulièrement de levage destinés à établir une jonction temporaire entre deux extrémités en forme de boucle, d'une ou de deux sangles, éventuellement une extrémité en forme de boucle d'une sangle avec un autre dispositif de forme adaptée.The present invention relates to accessories for lashing straps and more particularly lifting straps intended to establish a temporary junction between two loop-shaped ends, of one or two straps, possibly a loop-shaped end of a strap with another device of suitable shape.
De tels accessoires de jonction peuvent être utilisés pour relier entre elles des sangles trop courtes pour l'usage recherché, ou pour joindre entre elles un ensemble de sangles volontairement fraction¬ né pour des commodités d'utilisation. Ils doivent être aisément mani- pulables.à main nue.Such junction accessories can be used to connect together straps that are too short for the intended use, or to join together a set of straps that are deliberately fraction¬ born for convenience of use. They must be easy to handle.
Ces accessoires de jonction supportent intégralement la tension à laquelle sont soumises les sangles qu'ils relient. Ce sont donc des dispositifs très sollicités, surtout lorsqu'ils sont utilisés pour lever de lourdes charges. C'est là que réside la difficulté de leur réalisation.These joining accessories fully support the tension to which the straps they connect are subjected. They are therefore very stressed devices, especially when they are used to lift heavy loads. Therein lies the difficulty of their realization.
Les accessoires de jonction existant à l'heure actuelle ont, du fait, des contraintes qu'ils subissent, des formes et dimensions telles qu'ils débordent des faces externes utiles des sangles qu'ils relient, ce qui est mis en évidence sur la planche I figure A. On connaît déjà des moyens de joindre des sangles entre elles, ou des sangles avec d'autres dispositifs, par leurs extrémités formant boucle.The junction accessories existing at present have, due to the constraints that they undergo, shapes and dimensions such that they extend beyond the useful external faces of the straps that they connect, which is highlighted on the plate I figure A. We already know means of joining straps together, or straps with other devices, by their ends forming a loop.
Une solution consiste à passer dans chaque boucle une tige filetée à chaque extrémité et de chaque côté des sangles, un flasque percé de deux trous permettant le passage des extrémités des tiges puis de visser des écrous à ces extrémités (Ce montage rappelle celui des chaînes de bicyclettes).One solution consists in passing in each loop a threaded rod at each end and on each side of the straps, a flange pierced with two holes allowing the passage of the ends of the rods then to screw nuts at these ends (This assembly recalls that of the chains of bicycles).
Une solution voisine est partiellement décrite dans le docu¬ ment " US-A- 3583.751 (ERVING F. WHITE)", les tiges filetées étant alors remplacées par des boulons.A similar solution is partially described in the document "US-A- 3583.751 (ERVING F. WHITE)", the threaded rods then being replaced by bolts.
Une autre solution connue, consiste à enfiler les boucles des sangles sur un cavalier fileté à chaque extrémité, puis un flasque percé de deux trous, et visser deux écrous sur chaque extrémité.Another known solution consists in threading the buckles of the straps on a threaded jumper at each end, then a flange pierced with two holes, and screwing two nuts on each end.
Une solution voisine de celle-ci, consiste en un cavalier muni de deux trous alignés dans le même axe, par lesquels on enfile un boulon fermant l'ensemble tel que décrit dans le document " DE-B-1204.375 (AERO- QUIP A.G.) ".A similar solution to this consists of a jumper provided with two holes aligned in the same axis, through which a bolt closing the assembly is threaded as described in the document "DE-B-1204.375 (AERO-QUIP AG) ".
Ces montages sont pejt.commodes, long à réaliser, et nécessitent des outils_;de serrage, sans compter les risques que présente un montage encombrant.These assemblies are pejt.commodes, long to realize, and require tools_; tightening, not to mention the risks that a bulky assembly presents.
Les sangles et accessoires de jonction sont souvent utilisés pour arrimer ou lever des objets fragiles. Si la jonction se situe à l'endroit d'une portée des sangles contre l'objet, il n'est pas possible d'utiliser les accessoires de jonction déjà décrits sans risquer une dé¬ térioration de l'objet pendant la manutention ou le transport. Il est alors nécessaire de prévoir une protection supplémentaire ou d'autres moyens de manutention.Straps and junction accessories are often used to secure or lift fragile objects. If the junction is located at a point where the straps reach against the object, it is not possible to use the junction accessories already described without risking deterioration of the object during handling or transport. It is then necessary to provide additional protection or other means of handling.
O\ÎPI Si de tels accessoires sont utilisés pour l'arrimage d'objets à stocker, l'épaisseur des accessoires entraîne un volume perdu non né¬ gligeable et le risque de détérioration s'étend aux objets mitoyens à celui qui est arrimé.O \ ÎPI If such accessories are used for securing objects to be stored, the thickness of the accessories results in a non-negligible lost volume and the risk of deterioration extends to objects adjoining the one which is stowed.
On connaît déjà des solutions permettant de pallier à ces in¬ convénients. Elles sont décrites dans les documents " FR-A-703.875 (CAHEN & Fils) " et "GB-A-903.044 (C. BLANKENHORN)".Solutions are already known which make it possible to overcome these disadvantages. They are described in the documents "FR-A-703.875 (CAHEN & Fils)" and "GB-A-903.044 (C. BLANKENHORN)".
Il s'agit d'une pièce de jonction présentant deux tiges sur lesquelles sont enfilées les boucles des sangles, munie d'un système pivotant sur l'une des tiges et se rabattant sur l'autre, de manière à empêcher le dégagement des sangles et à excercer une résistance à l'é- cartement des tiges lorsque les sangles sont sous tension. Le maintien de la pièce pivotante en position fermée, est assuré par la flexibilité des tiges qui agissent comme des ressorts et excercent une pression sur la pièce pivotante, cette pression empêchant la pièce pivotante de se dé¬ gager et de s'ouvrir inopinément.It is a junction piece presenting two rods on which the buckles of the straps are threaded, provided with a system pivoting on one of the rods and folding back on the other, so as to prevent the release of the straps and to exert resistance to the spacing of the rods when the straps are under tension. Maintaining the pivoting part in the closed position is provided by the flexibility of the rods which act as springs and exert pressure on the pivoting part, this pressure preventing the pivoting part from disengaging and unexpectedly opening.
Un tel dispositif est utilisable avec des sangles de petites dimensions, lanières, ceintures à usage vestimentaire, domestique ou de bureau où les efforts auxquels il est soumis, sont .très faibles. Mais il présente deux inconvénients majeurs, qui ne permettraient pas son utilisation avec des sangles de levage ou d'arrimage qui sont soumises à des efforts très importants (Force de rupture allant de 2O0O DaN à 60.000 DaN environ, suivant les modèles).Such a device can be used with small straps, straps, belts for clothing, household or office use where the forces to which it is subjected are very low. But it has two major drawbacks, which would not allow its use with lifting or lashing straps which are subjected to very large forces (breaking force ranging from 2O0O DaN to 60,000 DaN approximately, depending on the model).
D'une part, en utilisation manuelle, pour supporter les efforts cités, les dimensions des tiges les rendraient parfaitement rigides et ne permettraient pas de profiter de leur élasticité pour assurer le serrage de la pièce pivotante en position fermée. Il est alors nécessaire d'avoir recours à un système de verrouillage supplémentaire.On the one hand, in manual use, to withstand the forces mentioned, the dimensions of the rods would make them perfectly rigid and would not allow them to take advantage of their elasticity to ensure the tightening of the pivoting part in the closed position. It is then necessary to use an additional locking system.
D'autre part, le principe de ce dispositif nécessite un axe de rotation de la pièce pivotante, sur l'une des tiges. Cet axe supporte l'effort d'écartement des tiges soumises à la tension des sangles.On the other hand, the principle of this device requires an axis of rotation of the pivoting part, on one of the rods. This axis supports the spacing force of the rods subjected to the tension of the straps.
OMPI Il doit donc être fortement di ensionné. En plus, cet axe traverse deux pièces : la tige et la pièce pivotante. Les trous ainsi pratiqués, re- 105 présentent un affaiblissement important des deux pièces citées. Pour avoir une résistance suffisante, ces pièces devraient être surdimen- sionnées à cet endroit. Pour obtenir une résistance équivalente, il faudrait doubler les dimensions de ces pièces.WIPO It must therefore be strongly dimensioned. In addition, this axis crosses two parts: the rod and the pivoting part. The holes thus made, represented by 1 0 5, show a significant weakening of the two cited parts. To have sufficient strength, these parts should be oversized in this location. To obtain equivalent resistance, it would be necessary to double the dimensions of these parts.
HO Ce dispositif, muni d'un axe, de par les dimensions de ses pièces constitutives, ne pourrait être utilisé pour la jonction de san¬ gles de levage et d'arrimage car il présente le même inconvénient d'en¬ combrement, donc du risque de détérioration que les Solutions précé¬ demment citées.HO This device, provided with an axis, by the dimensions of its constituent parts, could not be used for the junction of lifting and securing straps because it has the same drawback of space, therefore risk of deterioration than the previously mentioned Solutions.

La présente invention a pour but de remédier à ces inconvé¬ nients. Elle vise à supprimer les risques de détérioration d'objets manu¬ tentionnés par des sangles reliées par un accessoire de jonction, ainsi que des objets susceptibles d'entrer en contact avec cet accessoire, etThe object of the present invention is to remedy these drawbacks. It aims to eliminate the risks of deterioration of objects manu¬ tended by straps connected by a junction accessory, as well as objects likely to come into contact with this accessory, and

L'invention concerne donc un accessoire de jonction de sangle 125 de levage ou d'arrimage du type rappelé ci-dessus, comprenant une pièce en " U " dont chacune des branches est destinée à être engagée dans une boucle d'extrémité des sangles et un dispositif évitant l'écartement des branches sous tension et le dégagement inopiné des sangles, caractérisé en ce que le dit dispositif est constitué d'un manchon de faible épais- 130 seur faisant le tour complet des dites branches et glissant librement sur celles-ci jusqu'à complet dégagement des dites branches, sans axe de rotation avec l'une des dites branches, et muni d'un dispositif sup¬ plémentaire de verrouillage sur les dites branches, assurant la sécurité de l'assemblage. Ce dispositif de jonction de sangles ou "Epingle de 135 jonction extra-plate pour sangles", est extra-plat, formé de deux par¬ ties aisément démontables et n'ayant aucune saillie par rapport aux faces utiles des sangles à relier.The invention therefore relates to an accessory for joining the strap 125 for lifting or securing of the type mentioned above, comprising a U-shaped part, each of the branches of which is intended to be engaged in an end loop of the straps and a device avoiding the separation of the branches under tension and the unexpected release of the straps, characterized in that the said device consists of a thin sleeve 130 making the complete turn of the said branches and sliding freely on them until complete release of said branches, without axis of rotation with one of said branches, and provided with an additional locking device on said branches, ensuring the safety of the assembly. This strap joining device or "135 pin extra-flat joining for straps" is extra-flat, formed of two easily removable parts and having no projection relative to the useful faces of the straps to be connected.
O PI Il est représenté planche II et comprend :O PI It is represented plate II and includes:
140 D'une part, un corps ayant la forme générale d'un " U " dont les deux branches sont très allongées, rapprochées et parallèles. Chaque extrémité libre de ces branches est enfilée dans une boucle d'extrémité de sangle. La longueur des branches est supérieure à la largeur des san¬ gles, si bien que les boucles de sangles étant en place, les extrémités140 On the one hand, a body having the general shape of a "U" whose two branches are very elongated, close together and parallel. Each free end of these branches is threaded through a strap end loop. The length of the branches is greater than the width of the straps, so that the strap loops are in place, the ends

Les extrémités des branches sont telles qu'elles s'adaptent à la deuxiè¬ me partie de l'épingle.145 of the branches of the pin body are again visible and free. The ends of the branches are such that they adapt to the second part of the pin.
Cette deuxième partie de l'épingle est un dispositif de maintien 150 et de verrouillage du corps. Son rôle est d'éviter d'une part que les sangles ne se dégagent accidentellement de l'épingle au cours de la ma¬ nutention, d'autre part, que le corps ne se déforme par écartement des branches sous l'effet de la tension des sangles, afin d'assurer une ma¬ nipulation manuelle aisée. 155This second part of the pin is a device 150 for holding and locking the body. Its role is to prevent on the one hand that the straps do not accidentally disengage from the pin during the handling, on the other hand, that the body is not deformed by separation of the branches under the effect of the tension of the straps, in order to ensure easy manual manipulation. 155
Le dispositif selon l'invention est de, pré érence un manchon faisant le tour complet des branches de l'épingle. Mais ce manchon peut avoir la forme très aplatie d'une clavette à deux têtes qui est engagée dans une fente axiale ménagée dans chacune des extrémités libres des 160 branches du corps en " U ", chaque tête épousant la surface extérieure de l'extrémité des branches.The device according to the invention is , pre erence a sleeve making the complete turn of the branches of the pin.

Le manchon peut-être engagé ou dégagé librement sur les deux têtes des branches et comporte des moyens pour le bloquer sur celles-ci. 165The sleeve can be freely engaged or released on the two heads of the branches and includes means for locking it thereon. 165
On peut prévoir un taraudage sur les faces internes, en vis-à- vis, des extrémités des branches, le manchon portant une vis axiale tour- . na t folle sur celui-ci et filetée aux mêmes dimensions que le taraudage . de manière que l'ensemble soit solidarisé par vissage» 170It is possible to provide a tapping on the internal faces, facing each other, of the ends of the branches, the sleeve carrying an axial screw. na mad on it and threaded to the same dimensions as the thread. so that the whole is secured by screwing ”170
On peut aussi munir les extrémités libres de chaque branche d'encoches, le manchon portant deux leviers pivotant sur un axe solidaire du manchon, munis chacun d'un épaulement engageant ou non les encoches des branches. 175 On voit donc clairement que l'invention garantit contre tout décrochage involontaire des sangles et que les manipulations sont tou¬ jours réalisables sans précautions spéciales.It is also possible to provide the free ends of each branch with notches, the sleeve carrying two levers pivoting on an axis integral with the sleeve, each provided with a shoulder engaging or not engaging the notches of the branches. 175 It is therefore clearly seen that the invention guarantees against any involuntary release of the straps and that the manipulations are always possible without special precautions.

Sous l'effet du ressort les épaulements des leviers restent bloqués dans les encoches des branches et empêchent le manchon de se dégager du corps205 levers hitherto separated under the effect of the spring retract in front of the branches and their shoulders are housed in two notches mena¬ gées at the end of the branches by resuming their initial spacing. Under the effect of the spring the shoulders of the levers remain blocked in the notches of the branches and prevent the sleeve from coming off the body
210 de l'épingle.210 of the pin.
OMPI Pour ouvrir l'épingle, il est nécessaire de rapprocher les deux leviers à la main entre le pouce et l'index en sOpposant à l'effet du ressort. Les leviers en se rapprochant dégagent leurs épaulements des encoches pratiquées dans les branches. Il suffit ensuite de glisser 215 le manchon le long des branches pour le dégager entièrement du corps de l'épingle.WIPO To open the pin, it is necessary to bring the two levers together by hand between the thumb and the index finger, opposing the effect of the spring. The levers in approach release their shoulders from the notches in the branches. Then simply slide the sleeve 215 along the branches to release it entirely from the body of the pin.
Ilème exemple Î II ne diffère du précédent que par son dispo¬ sitif de verrouillage solidaire du manchon (1) et constitué par une vis 220 (7) tournant folle dans l'axe de celui-ci et retenu par une bague (8) logée dans une gorge pratiquée dans la vis. La tête de manoeuvre de la vis se trouve à l'extérieur du manchon, la partie filetée à l'intérieur.Ileme example Î II differs from the previous one only by its locking device secured to the sleeve (1) and constituted by a screw 220 (7) turning madly in the axis of the latter and retained by a ring (8) housed in a groove in the screw. The screw operating head is located outside the sleeve, the threaded part inside.
Lors de la mise en place du manchon la partie filetée de la vis 225 se présente entre les deux extrémités des branches de l'épingle, lesquel¬ les sont taraudées sur leurs faces internes opposées (F.3, F. ). La rota¬ tion manuelle de la vis par rapport au manchon entraîne l'engagement de celle-ci entre les branches de l'épingle et le glissement du manchon sur ses branches. En fin de course, la tête de la vis vient serrer le cou- 230 vercle soudé sur le manchon et assure le blocage de l'ensemble.When the sleeve is put in place, the threaded part of the screw 225 is between the two ends of the branches of the pin, which are tapped on their opposite internal faces (F.3, F.). The manual rota¬ tion of the screw relative to the sleeve causes the engagement of the latter between the branches of the pin and the sliding of the sleeve on its branches. At the end of the stroke, the head of the screw tightens the cover 230 welded to the sleeve and secures the assembly.
Pour ouvrir l'épingle on réalise l'opération inverse, le dévis¬ sage de la vis dégage le manchon des branches de l'épingle.In order to open the pin, the reverse operation is carried out, the removal of the screw releases the sleeve from the branches of the pin.
235 Ce dispositif de verrouillage ne peut, bien sûr, être utilisé que lorsque la largeur du passage des sangles entre les extrémités des branches est inférieure à la largeur interne du manchon, donc pour des épingles conçues pour des sangles de faible épaisseur.235 This locking device can, of course, only be used when the width of the passage of the straps between the ends of the branches is less than the internal width of the sleeve, therefore for pins designed for thin straps.
240 Illème exemple : Planche III, figure C et C , représentant une épingle qui diffère des précédentes par l'ensemble de son dispositif de maintien et de verrouillage.240 Illème example: Plate III, figure C and C, representing a pin which differs from the previous ones by the whole of its holding and locking device.
Celui-ci est constitué d'un manchon dans lequel les parois la- 245 térales auraient été rapprochées pour ne constituer qu'une seule et même âme centrale, les parties extrêmes du manchon formant deux têtes, le man¬ chon prend ainsi la forme particulière d'une clavette à deux têtes (9). Les extrémités des branches du corps (1) de l'épingle présen¬ tent alors deux fentes (une sur chaque branche), dans le prolongement 250 l'une de l'autre, dont la largeur correspond à l'épaisseur de l'âme de la clavette, laquelle glisse dans les deux fentes, lors de l'assemblage, les têtes de la clavette se trouvant de part et d'autre à l'extérieur des branches du corps de l'épingle.This consists of a sleeve in which the side walls 245 have been brought together to form a single central core, the end portions of the sleeve forming two heads, the sleeve thus takes the particular form a key with two heads (9). The ends of the branches of the body (1) of the pin then present two slots (one on each branch), in the extension 250 of one another, the width of which corresponds to the thickness of the core of the key, which slides in the two slots, during assembly, the heads of the key being on either side outside the branches of the body of the pin.
255 Les sous-faces (F. ) des têtes de la clavette épousent les faces externes (F.l.) des extrémités des branches, et sous charge, trans¬ mettent l'effort d'ecartement des branches aux têtes et donc à l'âme de la clavette qui assure la cohésion de l'ensemble.255 The sub-faces (F.) of the heads of the key follow the external faces (Fl) of the ends of the branches, and under load, put the effort of spreading the branches to the heads and therefore to the core of the key which ensures the cohesion of the whole.
260 Le dispositif de verrouillage est constitué d'une vis (lO) d'un diamètre plus fort que la largeur de la fente des branches.260 The locking device consists of a screw (10) with a diameter larger than the width of the branch slot.
Après la mise en place de la clavette au fond des fentes des branches, ce système est vissé entre les faces des fentes présentant à 265 ;cet endroit un évidement taraudé (F.Il) s'adaptant à la forme filetéeAfter the installation of the key at the bottom of the slots of the branches, this system is screwed between the faces of the slots having at 265; this place a threaded recess (F.Il) adapting to the threaded shape
(F.IO) de la vis. En place, ce système fait obstacle au dégagement de la clavette des branches de l'épingle.(F.IO) of the screw. In place, this system obstructs the release of the key from the branches of the pin.
Ce dispositif peut-être utilisé lorsque l'écartement des branches 270 est important, en cas-de jonction de sangles de forte épaisseur, ne per¬ mettant plus d'assurer un verrouillage satisfaisant avec le dispositif à leviers articulés.This device can be used when the spacing of the branches 270 is large, in case of joining of thick straps, no longer making it possible to ensure satisfactory locking with the device with articulated levers.
On voit que dans tous les cas, l'invention permet sous un 275 volume minimal ne dépassant pas les faces utiles des sangles, une mani¬ pulation simple et sure des charges à déplacer.It can be seen that in all cases, the invention allows, under a minimum volume of 275 not exceeding the useful faces of the straps, simple and safe handling of the loads to be moved.
L'invention est applicable dans tous les doma nes d'utilisation des sangles de levage et d'arrimage et plus particulièrement dans le cas 280 de levage ou d'arrimage d'objets fragiles risquant une détérioration avec un accessoire de type connu. L'intérêt est d'autant plus grand si les sangles sont volontairement fractionnées pour des commodités d'utilisation.The invention is applicable in all areas of use of lifting and securing straps and more particularly in the case of lifting or securing fragile objects risking deterioration with an accessory of known type. The interest is all the greater if the straps are voluntarily split for convenience of use.
O PI C'est le cas pour le levage et la manutention des bateaux (de plaisance notamment) à terre. 285O PI This is the case for the lifting and handling of boats (especially pleasure boats) on land. 285
Les systèmes connus comprennent deux sangles formant un berceau sous la coque du bateau à déplacer, et dont les extrémités sont reliées à un crochet de grue, ou un portique, donc à une hauteur plus élevée que la coque elle-même. 290Known systems include two straps forming a cradle under the hull of the boat to be moved, and the ends of which are connected to a crane hook, or a gantry, therefore at a higher height than the hull itself. 290
La mise en place des sangles sous la coque nécessite la dépose d'une extrémité des sangles, leur passage sous la coque puis leur repose sur le crochet soit une opération longue et acrobatique.The establishment of the straps under the hull requires the removal of one end of the straps, their passage under the hull and then rests on the hook is a long and acrobatic operation.
295 L'invention permet d'utiliser des sangles en deux parties re¬ liées à une extrémité au crochet de levage et qui ne seront pas déposées lors de la manoeuvre. Les autres extrémités pendent de part et d'autre de la coque. Il reste à relier ces extrémités avec l'épingle extra-plate qui, lors du levage est séparée de la coque par l'.épaisseur de la sangle295 The invention allows the use of two-part straps re¬ linked at one end to the lifting hook and which will not be removed during the maneuver. The other ends hang on either side of the hull. It remains to connect these ends with the extra-flat pin which, during lifting is separated from the hull by the thickness of the strap.
300 et ne risque donc pas de détériorer la coque du bateau. Le démontage est aussi, aisé en reprenant l'opération inverse ; la personne assurant la manoeuvre opérant toujours au sol et sans lever les bras. 300 and therefore does not risk damaging the hull of the boat. Disassembly is also easy by taking the reverse operation; the person carrying out the maneuver still operating on the ground and without lifting his arms.
