Description

DISPOSITIF D'ENROULEMENT D'UN LIEN SOUPLE  DEVICE FOR WINDING A FLEXIBLE LINK
Domaine technique Technical area
La présente invention concerne un dispositif d'enroulement d'un lien souple, notamment d'un câble, d'une corde, d'un câble de treuil, d'une corde de rappel ou similaire, ce dispositif comportant une embase portant une poulie rotative montée sur ladite embase, cette poulie comportant au moins une gorge dans laquelle est disposé un segment dudit lien souple. Technique antérieure  The present invention relates to a device for winding a flexible link, in particular a cable, a rope, a winch cable, a return rope or the like, this device comprising a base carrying a pulley rotary mounted on said base, this pulley having at least one groove in which is disposed a segment of said flexible link. Prior art
Les treuils sont habituellement constitués d'une poulie sur laquelle est enroulée une longueur déterminée de câble ou de corde ou de ruban, cette poulie étant associée à un moyen d'entraînement qui peut être manuel ou motorisé. Les treuils couramment utilisés dans le domaine du nautisme, sur les véhicules tout-terrain, sur les tracteurs agricoles ou forestiers, dans le domaine du sauvetage, de l'alpinisme ou dans d'autres domaines professionnels ou sportifs sont tous basés sur une même conception selon laquelle le câble est enroulé sur une poulie qui porte un ensemble d'enroulements juxtaposés et superposés. Notamment sur de petits treuils qui ne sont pas équipés de moyens de trancanage permettant d'ajuster les spires parallèles entre elles de façon juxtaposée et ordonnée, les enroulements se chevauchent souvent de façon désordonnée. On sait que cette superposition génère une usure par friction aboutissant à terme à la rupture de brins métalliques et à la rupture du câble. En outre, la capacité du treuil est définie par la longueur du lien souple enroulé sur la poulie, ce qui la limite obligatoirement.  The winches usually consist of a pulley on which is wound a given length of cable or rope or ribbon, this pulley being associated with a drive means which can be manual or motorized. Winches commonly used in the field of boating, on all-terrain vehicles, on agricultural or forestry tractors, in the field of rescue, mountaineering or in other professional or sports fields are all based on the same design wherein the cable is wound on a pulley which carries a set of windings juxtaposed and superimposed. In particular on small winches which are not equipped with slicing means for adjusting the parallel turns together in a juxtaposed and orderly manner, the windings often overlap in a disordered manner. It is known that this superposition generates a frictional wear leading eventually to the breaking of metal strands and breaking of the cable. In addition, the capacity of the winch is defined by the length of the flexible link wound on the pulley, which necessarily limits it.

Meilleures manières de réaliser l'invention Best ways to achieve the invention
En référence aux figures 1A et 1B, le dispositif d'enroulement 10 d'un lien souple, tel que représenté, comporte une embase 11 qui porte une poulie rotative 12, par exemple montée sur un axe central 13. Dans cette variante de réalisation, la poulie est entraînée par un moteur 14 qui est couplé à une boîte de réduction 15 dont la sortie est en prise avec l'axe central 13. Le moteur 14 et la boîte de réduction 15 sont montés sous l'embase 1 qui sert de platine de support à l'ensemble des composants du dispositif 10. La poulie 12 comporte une gorge 16 du type auto-serrante ou autobloquante ayant un profil en forme de V ou de V tronqué, et deux flancs latéraux pourvus de cannelures 17 et dont l'écartement se réduit progressivement en fonction de la profondeur de la gorge pour enserrer un lien souple du type cordage ou similaire et empêcher son glissement longitudinal. La gorge en forme de V a l'avantage de pouvoir recevoir plusieurs types de cordes ou câbles de sections différentes qui, selon leur diamètre, peuvent s'engager plus ou moins profondément dans la gorge 16 de la poulie 12.  With reference to FIGS. 1A and 1B, the winding device 10 of a flexible link, as represented, comprises a base 11 which carries a rotary pulley 12, for example mounted on a central axis 13. In this variant embodiment, the pulley is driven by a motor 14 which is coupled to a reduction gearbox 15 whose output is engaged with the central axis 13. The motor 14 and the reduction gearbox 15 are mounted under the base 1 which serves as platinum The pulley 12 comprises a groove 16 of the self-locking or self-locking type having a V-shaped or V-truncated profile, and two lateral flanks provided with grooves 17 and of which spacing is gradually reduced depending on the depth of the groove to enclose a flexible link type rope or the like and prevent longitudinal slippage. The V-shaped groove has the advantage of being able to receive several types of ropes or cables of different sections which, depending on their diameter, may engage more or less deeply in the groove 16 of the pulley 12.
La figure 1A montre en particulier la construction de la poulie rotative 12 qui a une forme de cloche fixée par une goupille 22 à l'axe 13 et montée par l'intermédiaire d'un roulement 23 à billes ou à rouleaux ou similaire sur une pièce tubulaire 24 solidaire de l'embase 11. Un roulement à billes 25 maintient la poulie rotative 12 à distance de l'embase 11. FIG. 1A shows in particular the construction of the rotary pulley 12 which has a bell shape fixed by a pin 22 to the pin 13 and mounted by means of a ball bearing 23 or roller bearings or the like on a piece tubular 24 integral with the base 11. A ball bearing 25 keeps the rotary pulley 12 away from the base 11.
L'ensemble est complété par au moins un organe de renvoi 19 du lien souple qui est fixe par rapport à la poulie 12. Dans cette forme de réalisation cet organe de renvoi 19 est constitué de trois plots 20a, 20b et 21. Les deux plots 20a et 20b sont appelés plots latéraux et le plot 21 est appelé plot central. Comme représenté par la figure 3A, Les deux plots latéraux 20a et 20b sont respectivement disposés dans le prolongement de deux rayons du cercle représentant la poulie 12 et symétriquement par rapport au prolongement du rayon passant par le plot central 21. Ils sont en outre disposés de préférence à proximité de la périphérie de la poulie 12 et peuvent être pratiquement tangents à cette périphérie. Cette forme de réalisation est la plus complète et permet d'élargir le champ des utilisations du dispositif d'enroulement de l'invention. The assembly is completed by at least one deflection member 19 of the flexible link which is fixed relative to the pulley 12. In this embodiment this return member 19 consists of three studs 20a, 20b and 21. The two studs 20a and 20b are called lateral pads and the stud 21 is called central stud. As represented by FIG. 3A, the two lateral pads 20a and 20b are respectively arranged in the extension of two radii of the circle representing the pulley 12 and symmetrically with respect to the extension of the radius passing through the central stud 21. They are furthermore preferably arranged close to the periphery of the pulley 12 and may be practically tangent at this periphery. This embodiment is the most complete and allows to expand the scope of uses of the winding device of the invention.
Le dispositif d'enroulement 10 d'un lien souple de la figure 2 se distingue de celui des figures 1A et 1B en ce que la poulie rotative 12 est entraînée manuellement par une manivelle 30 qui est rendue solidaire de la poulie par une goupille 22 ou similaire. Dans cette réalisation il n'y a ni moteur d'entraînement ni boîte de réduction, les autres composants étant sensiblement similaires à ceux décrits précédemment. Les figures 3B et 3C illustrent en vue de dessus simplifiée deux autres formes de réalisation de l'organe de renvoi 19 pouvant équiper le dispositif d'enroulement 10 d'un lien souple selon l'invention. The winding device 10 of a flexible link of FIG. 2 differs from that of FIGS. 1A and 1B in that the rotary pulley 12 is driven manually by a crank 30 which is secured to the pulley by a pin 22 or similar. In this embodiment there is neither drive motor nor reduction box, the other components being substantially similar to those described above. FIGS. 3B and 3C illustrate, in simplified top view, two other embodiments of the deflection member 19 that can equip the winding device 10 with a flexible link according to the invention.
Dans la réalisation selon la figure 3B l'organe de renvoi 19 n'est constituée que du plot central 21 disposé dans le prolongement d'un rayon du cercle représentant la poulie 12. Dans la réalisation selon la figure 3C, cet organe de renvoi 19 n'est constitué que des deux plots latéraux 20a et 20b, respectivement disposés dans le prolongement de deux rayons du cercle représentant la poulie 12 et de préférence à proximité de la périphérie de cette poulie 12. In the embodiment according to FIG. 3B the deflection member 19 consists only of the central stud 21 arranged in the extension of a radius of the circle representing the pulley 12. In the embodiment according to FIG. 3C, this return member 19 consists only of two lateral studs 20a and 20b, respectively arranged in the extension of two radii of the circle representing the pulley 12 and preferably close to the periphery of this pulley 12.
La figure 4A montre l'utilisation du dispositif d'enroulement tel que représenté par la figure 3B. Le lien souple, en l'occurrence un câble ou une corde 40, est enroulé sur la poulie 12. Une seule boucle de ce lien souple est prise dans la gorge de la poulie dont le profil est conçu pour assurer son auto-serrage ou un son auto- blocage. L'une des extrémités 41 du lien souple est tendue et sert à tirer ou à retenir un objet (non représenté). L'autre extrémité 42 est libre. On notera que les deux extrémités 41 et 42 du lien souple 40, séparées par le plot central 21 de l'organe de renvoi 19, forment un angle approximativement égal à 360°. Figure 4A shows the use of the winding device as shown in Figure 3B. The flexible link, in this case a cable or rope 40, is wound on the pulley 12. A single loop of this flexible link is taken in the throat of the pulley whose profile is designed to ensure its self-tightening or a his self-blocking. One end 41 of the flexible link is stretched and serves to pull or hold an object (not shown). The other end 42 is free. It should be noted that two ends 41 and 42 of the flexible link 40, separated by the central stud 21 of the return member 19, form an angle approximately equal to 360 °.
La figure 4B montre une l'utilisation du dispositif d'enroulement tel que représenté 5 par la figure 3C. Le lien souple, en l'occurrence un câble ou une corde 50, est enroulé sur la poulie 12. Une seule boucle de ce lien souple est prise dans la gorge de la poulie dont le profil est conçu pour assurer un auto-serrage ou un auto-blocage de ce lien souple. L'une des extrémités 51 du lien souple est tendue et sert à tirer ou à retenir un objet (non représenté). L'autre extrémité 52 est libre, î o Les deux extrémités sont séparées par les deux plots latéraux 20a et 20b de l'organe de renvoi 19 et forment un angle qui est, dans ce cas, légèrement supérieur à 180°. L'ouverture angulaire dépend de la position des deux plots latéraux 20a et 20b et peut varier entre 180° et 360°. Figure 4B shows a use of the winding device as shown in Figure 3C. The flexible link, in this case a cable or a rope 50, is wound on the pulley 12. A single loop of this flexible link is taken in the throat of the pulley whose profile is designed to ensure a self-tightening or a self-locking this flexible link. One of the ends 51 of the flexible link is stretched and used to pull or hold an object (not shown). The other end 52 is free, the two ends are separated by the two lateral pads 20a and 20b of the deflection member 19 and form an angle which is, in this case, slightly greater than 180 °. The angular aperture depends on the position of the two lateral pads 20a and 20b and can vary between 180 ° and 360 °.
15 II est bien entendu que la poulie peut être associée à tout mécanisme ou dispositif de freinage, de limitation du couple, d'embrayage, d'entraînement ou de blocage. Ce mécanisme ou dispositif n'est pas représenté sur les figures parce qu'il est connu en soi. Les utilisations sont diverses, par exemple une utilisation comme treuil fixe ou comme treuil mobile. Le treuil fixe est utilisé pour tracter un objet, parIt is understood that the pulley can be associated with any mechanism or device for braking, torque limitation, clutch, driving or blocking. This mechanism or device is not shown in the figures because it is known per se. The uses are diverse, for example use as a fixed winch or as a mobile winch. The fixed winch is used to tow an object, by
20 exemple lorsqu'il est destiné à une utilisation agricole ou forestière. Le treuil mobile fonctionne avec un câble fixe tendu et la poulie se déplace le long de ce câble en transportant par exemple une charge ou une nacelle ou similaire. Les réalisations spécifiques ne sont pas représentées et ne font pas partie de l'objet de la présente invention. For example when it is intended for agricultural or forestry use. The movable winch operates with a fixed wire tensioned and the pulley moves along this cable carrying for example a load or a nacelle or the like.
