Description

Dispositif de guidage et de blocage d'un cordage utilisable notamment à bord d'un voilier Device for guiding and locking a rope which can be used in particular on board a sailboat
La présente invention se rapporte à un dispositif de guidage et de blocage d'un cordage utilisable notamment à bord d'un voilier. II arrive fréquemment, pour la manœuvre d'un voilier, qu'un cordage soit réorienté à l'aide d'une poulie avant d'être saisi, soit manuellement, soit par l'intermédiaire d'un treuil. Une fois le réglage du cordage effectué, il est alors nécessaire de l'immobiliser dans cette position. Pour cela, il est classiquement utilisé un taquet d'amarrage en aval de la poulie ou du treuil éventuel. Cette solution est simple et fiable, mais présente l'inconvénient majeur, notamment dans le cas d'un cordage demandant des réglages peu fréquents, de rendre le taquet et surtout le treuil indisponibles pour d'autres manœuvres.The present invention relates to a device for guiding and blocking a rope which can be used in particular on board a sailboat. It frequently happens, for the operation of a sailboat, that a rope is redirected using a pulley before being gripped, either manually or by means of a winch. Once the rope has been adjusted, it is then necessary to immobilize it in this position. For this, it is conventionally used a mooring cleat downstream of the pulley or the possible winch. This solution is simple and reliable, but has the major drawback, in particular in the case of a rope requiring infrequent adjustments, to make the cleat and especially the winch unavailable for other maneuvers.
Pour pallier cela, il a été proposé des dispositifs de guidage et de blocage permettant de bloquer le cordage au niveau de la poulie. Un tel dispositif comprend généralement une poulie présentant une gorge circulaire recevant le cordage. Cette polie coopère avec une came pouvant passer d'une position de repli, dans laquelle la poulie est libre en rotation, à une position d'engagement dans laquelle la poulie est bloquée en rotation. En fonctionnement, une traction sur le cordage entraîne la came qui vient comprimer le cordage dans la gorge de la poulie. Néanmoins, cette came exerçant des contraintes sur une surface convexe et fuyante de la poulie, il en découle que le blocage en rotation de la poulie n'est qu'imparfaitement réalisé. Ces dispositifs sont ainsi limités à des utilisations de courte durée.To overcome this, guidance and blocking devices have been proposed making it possible to block the rope at the level of the pulley. Such a device generally comprises a pulley having a circular groove receiving the rope. This polished cooperates with a cam which can pass from a folding position, in which the pulley is free to rotate, to an engagement position in which the pulley is locked in rotation. In operation, a pull on the rope drives the cam which compresses the rope in the groove of the pulley. However, this cam exerting stresses on a convex and leaking surface of the pulley, it follows that the blocking in rotation of the pulley is only imperfectly achieved. These devices are thus limited to short-term uses.
La présente invention a pour but de résoudre les inconvénients évoqués précédemment, et concerne à cet effet un dispositif de guidage et de blocage d'un cordage utilisable notamment à bord d'un voilier, ce dispositif comprenant, d'une part, une poulie pourvue d'au moins une gorge pouvant recevoir un cordage relié aux voiles, et d'autre part, un élément de serrage apte à passer d'une position de repli, dans laquelle la poulie est libre en rotation, à une position d'engagement, dans laquelle la poulie est immobilisée, caractérisé en ce que la gorge de la poulie comprend un fond présentant un contour polygonal.The present invention aims to solve the drawbacks mentioned above, and for this purpose relates to a device for guiding and blocking a rope usable in particular on board a sailboat, this device comprising, on the one hand, a pulley provided at least one groove capable of receiving a rope connected to the sails, and on the other hand, a clamping element capable of passing from a folded-back position, in which the pulley is free to rotate, to an engagement position, in which the pulley is immobilized, characterized in that the groove of the pulley comprises a bottom having a polygonal contour.
Dans la présente demande, ce contour polygonal doit être compris comme étant un contour constitué par une suite ordonnée de segments dont chacun a une extrémité commune (ou sommet) avec le segment précédent et le segment suivant. La liaison entre deux sommets adjacents peut alors être réalisée par une facette plane ou par une surface bosselée par exemple. Ainsi, la surface de la gorge contre laquelle l'élément de serrage comprime le cordage étant plus importante que celle offerte dans un dispositif classique, il en découle, d'une part, que les contraintes exercées par l'élément de serrage sur le cordage sont considérablement plus élevées, et d'autre part, que la poulie est véritablement immobilisée en rotation.In the present application, this polygonal contour must be understood as being a contour constituted by an ordered series of segments each of which has a common end (or vertex) with the preceding segment and the following segment. The connection between two adjacent vertices can then be achieved by a planar facet or by a bumpy surface for example. Thus, the surface of the groove against which the tightening element compresses the cordage being larger than that offered in a conventional device, it follows, on the one hand, that the stresses exerted by the tightening element on the cordage are considerably higher, and on the other hand, that the pulley is truly immobilized in rotation.
Le fond de la gorge peut comprendre un nombre variable de facettes planes, et, en fonction du cordage associé à la poulie, il s'agit de trouver un compromis entre l'efficacité du blocage et la facilité d'utilisation de la poulie lorsque l'élément de serrage est en position de repli. En effet, les facettes sont d'autant plus longues et offrent une surface de serrage d'autant plus importante que leur nombre est réduit. En revanche, dans ce cas, la mise en rotation de la poulie est plus délicate à réaliser et les arêtes joignant les facettes, bien qu'étant arrondies, peuvent provoquer une usure prématurée du cordage au fil du temps. Il a été constaté que les meilleurs résultats sont obtenus à l'aide d'un fond présentant un contour hexagonal doté de facettes planes.The back of the groove may include a variable number of planar facets, and, depending on the rope associated with the pulley, it is a question of finding a compromise between the effectiveness of the blocking and the ease of use of the pulley when the the clamping element is in the folded position. Indeed, the facets are all the longer and offer a clamping surface that is larger the smaller their number. However, in this case, the rotation of the pulley is more difficult to achieve and the edges joining the facets, although being rounded, can cause premature wear of the rope over time. It has been found that the best results are obtained using a background having a hexagonal contour provided with planar facets.
Avantageusement, un dispositif selon l'invention comprend des moyens élastiques aptes à exercer des contraintes sur l'élément de serrage de façon à la faire passer dans la position d'engagement. Avantageusement encore, un dispositif selon l'invention comprend un dispositif de retrait permettant de placer l'élément de serrage en position de repli. Ce dernier peut alors être maintenu en position de repli à l'aide d'un mécanisme de verrouillage.Advantageously, a device according to the invention comprises elastic means capable of exerting stresses on the clamping element so as to cause it to pass into the engagement position. Advantageously also, a device according to the invention comprises a withdrawal device making it possible to place the clamping element in the folded position. The latter can then be kept in the folded-back position using a locking mechanism.
Selon un premier mode de réalisation préféré de l'invention, l'élément de serrage est constitué par une came pivotante. Dans ce cas, une première variante de réalisation du dispositif de retrait peut consister en un levier articulé autour de l'axe de la poulie et apte à coopérer avec un téton présenté par la came. Une deuxième variante de réalisation peut consister en un levier articulé autour de l'axe de la came et apte à coopérer avec un téton présenté par la came. Enfin, le dispositif de retrait peut également être réalisé à l'aide d'une tirette fixée de façon rigide dans la came.According to a first preferred embodiment of the invention, the clamping element is constituted by a pivoting cam. In this case, a first alternative embodiment of the withdrawal device may consist of a lever articulated around the axis of the pulley and able to cooperate with a stud presented by the cam. A second alternative embodiment may consist of a lever articulated around the axis of the cam and able to cooperate with a stud presented by the cam. Finally, the withdrawal device can also be produced using a pull rod rigidly fixed in the cam.
Selon un deuxième mode de réalisation préféré de l'invention, l'élément de serrage est constitué par un coin pouvant coulisser dans une glissière. Le dispositif de retrait associé peut alors être réalisé à l'aide d'un levier articulé autour de l'axe de la poulie et apte à coopérer avec une butée présentée par le coin, ou encore à l'aide d'une tirette fixée rigidement dans le coin par exemple.According to a second preferred embodiment of the invention, the clamping element is constituted by a corner which can slide in a slide. The associated withdrawal device can then be produced using a lever articulated around the axis of the pulley and able to cooperate with a stop. presented by the corner, or even using a zipper rigidly fixed in the corner for example.
L'invention sera mieux comprise à l'aide de la description détaillée qui est exposée ci-après en regard du dessin annexé dans lequel : La figure 1 est une vue en perspective d'un dispositif de guidage et de blocage selon le premier mode de réalisation préféré de l'invention, avec omission du cordage et du dispositif de retrait.The invention will be better understood using the detailed description which is set out below with reference to the appended drawing in which: FIG. 1 is a perspective view of a guiding and locking device according to the first mode of preferred embodiment of the invention, with omission of the rope and the removal device.
La figure 2 est une vue en coupe selon la ligne ll-ll du dispositif représenté à la figure 1 , lorsque l'élément de serrage est en position d'engagement.Figure 2 is a sectional view along line II-II of the device shown in Figure 1, when the clamping member is in the engagement position.
La figure 3 est une vue en coupe selon la ligne ll-ll du dispositif représenté à la figure 1 , lorsque l'élément de serrage est en position de repli.Figure 3 is a sectional view along line II-II of the device shown in Figure 1, when the clamping member is in the folded position.
Les figures 4 à 6 sont des vues en perspective du dispositif représenté à la figure 1 sur lequel est rapporté un dispositif de retrait. La figure 7 est une vue de dessus en coupe transversale d'un dispositif de guidage et de blocage selon le deuxième mode de réalisation préféré de l'invention.Figures 4 to 6 are perspective views of the device shown in Figure 1 on which is attached a removal device. Figure 7 is a top view in cross section of a guide and locking device according to the second preferred embodiment of the invention.
La figure 8 est une vue de dessus en coupe transversale d'une poulie comportant un fond présentant un contour polygonal réalisé à partir de surfaces bosselées.Figure 8 is a top view in cross section of a pulley having a bottom having a polygonal contour made from bumpy surfaces.
Un dispositif 1 de guidage et de blocage selon le premier mode de réalisation préféré de l'invention est représenté aux figures 1 à 3. Ce dispositif 1 comporte un socle 2 dans lequel sont intégrées une poulie 3 et une came 4. Plus précisément, la poulie 3 est mobile en rotation autour d'un axe 5 et comprend une gorge 6 dotée d'un fond hexagonal présentant six facettes 7 planes identiques. La came 4 est montée pivotante autour d'un axe 8 et possède des bossages 9 dans une zone destinée à venir au contact d'un cordage 10. La came 4 est positionnée dans le socle 2 de manière à ce que la distance mesurée entre l'axe 8 de la came 4 et le bossage 9 le plus éloigné dudit axe 8 soit supérieure à la plus petite distance mesurée entre ledit axe 8 et la facette 7 de la gorge 6 située en regard.A device 1 for guiding and locking according to the first preferred embodiment of the invention is shown in Figures 1 to 3. This device 1 comprises a base 2 in which are integrated a pulley 3 and a cam 4. More precisely, the pulley 3 is movable in rotation about an axis 5 and includes a groove 6 provided with a hexagonal bottom having six identical planar facets 7. The cam 4 is pivotally mounted about an axis 8 and has bosses 9 in an area intended to come into contact with a rope 10. The cam 4 is positioned in the base 2 so that the distance measured between l axis 8 of cam 4 and the boss 9 furthest from said axis 8 is greater than the smallest distance measured between said axis 8 and the facet 7 of the groove 6 located opposite.
Par ailleurs, un téton 11 est fixée dans la came 4, et cette dernière présente, du côté opposé à la poulie 3, un épaulement interne 12 dans lequel peut être inséré un cran 13 d'un dispositif de verrouillage 14 logé dans le socle 2. Comme représenté à la figure 2, lorsque le cran 13 du dispositif de verrouillage 14 est extrait de l'épaulement interne 12, des moyens élastiques (non représentés), comme par exemple un ressort spiral, forcent la came 4 à venir au contact du cordage 10 logé dans la gorge 6 de la poulie 3. Ainsi que le montrent la flèche, lorsqu'une traction est exercée sur le cordage 10, la poulie 3 ainsi que la came 4 sont tout d'abord entraînées en rotation dans des sens contraires. Certains bossages 9 de la came 4 sont alors amenés à comprimer le cordage 10 de plus en plus fortement contre la facette 7 située en regard. Il en découle finalement que la poulie 3 et que le cordage 10 se retrouvent immobilisés.Furthermore, a stud 11 is fixed in the cam 4, and the latter has, on the side opposite to the pulley 3, an internal shoulder 12 into which can be inserted a notch 13 of a locking device 14 housed in the base 2 . As shown in FIG. 2, when the notch 13 of the locking device 14 is extracted from the internal shoulder 12, elastic means (not shown), such as for example a spiral spring, force the cam 4 to come into contact with the rope 10 housed in the groove 6 of the pulley 3. As shown by the arrow, when traction is exerted on the rope 10, the pulley 3 as well as the cam 4 are first of all rotated in opposite directions. Certain bosses 9 of the cam 4 are then brought to compress the cord 10 more and more strongly against the facet 7 situated opposite. It finally follows that the pulley 3 and the rope 10 are immobilized.
Comme représenté à la figure 3, lorsque la came 4 est maintenue en position de repli grâce au dispositif de verrouillage 14 dont le cran 13 est inséré dans l'épaulement interne 12 de la came 4, le cordage 10 est plaqué contre les facettes 7 planes de la poulie 3, et cette dernière peut librement tourner autour de son axe 5 lorsqu'une traction est exercée sur la cordage 10.As shown in FIG. 3, when the cam 4 is kept in the folded-in position thanks to the locking device 14, the notch 13 of which is inserted in the internal shoulder 12 of the cam 4, the cord 10 is pressed against the planar facets 7 of the pulley 3, and the latter can freely rotate around its axis 5 when traction is exerted on the rope 10.
En se référant à la figure 4, on constate que la came 4 peut être emmenée en position de repli grâce à un dispositif de retrait réalisé à l'aide d'un levier 15 monté rotatif autour de l'axe 5 de la poulie 3. Plus précisément, un utilisateur peut se saisir du levier 15 et le forcer à pivoter dans le sens trigonometrique autour de l'axe 5. Ce faisant, ce levier 15 vient au contact du téton 11 , et provoque le pivotement de la came 4 autour de son axe 8 dans le sens des aiguilles d'une montre, et donc en direction du dispositif de verrouillage 14.Referring to FIG. 4, it can be seen that the cam 4 can be brought into the folded position thanks to a withdrawal device produced using a lever 15 mounted to rotate around the axis 5 of the pulley 3. More specifically, a user can take hold of the lever 15 and force it to pivot in the counterclockwise direction around the axis 5. In doing so, this lever 15 comes into contact with the stud 11, and causes the cam 4 to pivot around its axis 8 clockwise, and therefore towards the locking device 14.
En se référant à la figure 5, on observe que la came 4 peut être emmenée en position de repli grâce à un dispositif de retrait réalisé à l'aide d'un levier 16 monté rotatif autour de l'axe 8 de la came 4. Plus précisément, ce levier 16 présente une fente 17 incurvée dans laquelle est engagé le téton 11 de la came 4. Cette fente 17 incurvée correspond à un arc de cercle dont le centre est constitué par l'axe 8 de la came 4. Ainsi, un utilisateur peut se saisir du levier 16 et le forcer à pivoter autour de l'axe 5 dans le sens des aiguilles d'une montre. Ce faisant, ce levier 16 provoque le pivotement de la came 4 autour de son axe 8 dans le sens des aiguilles d'une montre et donc en direction de dispositif de verrouillage 14.Referring to FIG. 5, it can be seen that the cam 4 can be brought into the folded position thanks to a withdrawal device produced by means of a lever 16 rotatably mounted around the axis 8 of the cam 4. More precisely, this lever 16 has a curved slot 17 in which the stud 11 of the cam 4 is engaged. This curved slot 17 corresponds to an arc of circle whose center is formed by the axis 8 of the cam 4. Thus, a user can take hold of the lever 16 and force it to pivot around the axis 5 clockwise. In doing so, this lever 16 causes the cam 4 to pivot about its axis 8 clockwise and therefore in the direction of the locking device 14.
Enfin, comme représenté à la figure 6, un dispositif de retrait peut être réalisé à l'aide d'une tirette 18 qui est fixée de façon rigide dans le téton 11 de la came 4. Par conséquent, un utilisateur se saisissant de la tirette 18 peut très facilement faire pivoter la came 4 en direction du dispositif de verrouillage 14.Finally, as shown in FIG. 6, a removal device can be produced using a pull tab 18 which is rigidly fixed in the stud 11 of the cam 4. Consequently, a user grabbing the pull tab 18 may very easily rotate the cam 4 in the direction of the locking device 14.
Un dispositif 101 de guidage et de blocage selon le deuxième mode de réalisation préféré de l'invention est représenté à la figure 7. Ce dispositif 101 diffère uniquement de celui décrit précédemment par le fait qu'un coin 104 se substitue à la came 4 pivotante. Plus précisément, ce coin 104 présente deux tétons 111 qui sont insérés dans une glissière 108. Ainsi, lorsqu'un utilisateur fait coulisser le coin 104 dans la glissière 108 de façon à l'éloigner de la poulie 3, cette dernière est libre en rotation. En revanche, lorsque le mécanisme de verrouillage 14 n'est pas enclenché et que les moyens élastiques ont emmené le coin 104 au contact du cordage 10, une traction sur ce dernier provoque, d'une part, la mise en rotation de la poulie 3 dans le sens des aiguilles d'une montre, et d'autre part, le coulissement du coin 104 dans la glissière 108 en direction de la facette 7 de la gorge 6 située en regard. Le coin 104 comporte une face 109 qui est de ce fait amenée à comprimer le cordage 10 de plus en plus fortement contre ladite facette 7. Il en résulte finalement que la poulie 3 et que le cordage 10 se retrouvent immobilisés.A device 101 for guiding and blocking according to the second preferred embodiment of the invention is shown in FIG. 7. This device 101 differs only from that described above in that a wedge 104 replaces the pivoting cam 4 . More specifically, this corner 104 has two pins 111 which are inserted in a slide 108. Thus, when a user slides the corner 104 in the slide 108 so as to move it away from the pulley 3, the latter is free to rotate . On the other hand, when the locking mechanism 14 is not engaged and the elastic means have brought the wedge 104 into contact with the rope 10, traction on the latter causes, on the one hand, the pulley 3 to rotate. clockwise, and on the other hand, the sliding of the corner 104 in the slide 108 in the direction of the facet 7 of the groove 6 located opposite. The corner 104 has a face 109 which is therefore caused to compress the cord 10 more and more strongly against said facet 7. It ultimately results in the pulley 3 and the cord 10 being immobilized.
La figure 8 représente une poulie 203 pouvant se substituer à la poulie 3 dans les dispositifs 1 , 101 de guidage et de blocage. Cette poulie 203 comprend une gorge 206 comportant un fond présentant un contour hexagonal, chacune des facettes 7 planes ayant été remplacée par une surface bosselée 207 permettant de relier deux sommets 230 adjacents orientés vers l'extérieur. L'immobilisation de la poulie 203 et du cordage 10 peut être alors obtenue de manière tout à fait satisfaisante par coopération des surfaces bosselées 207 avec les bossages 9 de la came 4.FIG. 8 shows a pulley 203 which can replace the pulley 3 in the guiding and locking devices 1, 101. This pulley 203 comprises a groove 206 comprising a bottom having a hexagonal contour, each of the planar facets 7 having been replaced by a bumpy surface 207 making it possible to connect two adjacent vertices 230 oriented towards the outside. The immobilization of the pulley 203 and the rope 10 can then be obtained in a completely satisfactory manner by cooperation of the embossed surfaces 207 with the bosses 9 of the cam 4.
