Description

L'invention est relative à une poulie à bloqueur déverrouillable, comprenant un galet monté à rotation sur un premier flasque pour le guidage de la corde, une gâchette pivotante entre une position inactive et une position active, respectivement pour débloquer et bloquer la corde contre le galet, et des moyens de commande pour maintenir la gâchette dans la position inactive inhibant l'action du bloqueur.The invention relates to an unlockable locking pulley, comprising a roller rotatably mounted on a first flange for guiding the rope, a pivoting trigger between an inactive position and an active position, respectively to unlock and lock the rope against the rope. roller, and control means for holding the trigger in the inactive position inhibiting the action of the blocker.

État de la techniqueState of the art

Le document EP 803268 de la demanderesse décrit une poulie à bloqueur intégré du genre mentionné. Dans la position inactive, l'usage de l'appareil est réduit à une poulie classique sans bloqueur, étant donné que la gâchette est verrouillée en étant maintenue écartée du galet rotatif. Dans la position active, la gâchette est libre et est susceptible de bloquer la corde. Les moyens de commande pour le maintien de la poulie dans la position inactive, font partie de la gâchette par suite de l'introduction d'un mousqueton additionnel dans une lumière de cadenassage prévue dans la gâchette lorsque cette dernière est en position écartée. La surface de freinage et de coincement de la gâchette reste alors écartée du galet. La présence de ce mousqueton additionnel en plus du mousqueton d'attache complique néanmoins les opérations de manoeuvre de la poulie.The document EP 803268 of the Applicant describes an integrated blocking pulley of the kind mentioned. In the inactive position, the use of the apparatus is reduced to a conventional block without blocker, since the trigger is locked while being kept away from the rotating roller. In the active position, the trigger is free and is likely to block the rope. The control means for maintaining the pulley in the inactive position, are part of the trigger as a result of the introduction of an additional karabiner in a lockout lock provided in the trigger when the latter is in the remote position. The braking and jamming surface of the trigger is then separated from the roller. The presence of this additional carabiner in addition to the carabiner attachment nevertheless complicates the maneuvering operations of the pulley.

Objet de l'inventionObject of the invention

L'objet de l'invention consiste à réaliser une poulie à bloqueur intégré ayant un encombrement réduit, et pouvant facilement être manipulée.The object of the invention is to provide an integrated blocking pulley having a small footprint, and can easily be manipulated.

La poulie à bloqueur selon l'invention est caractérisée en ce que les moyens de commande comportent un verrou fixé sur le premier flasque, et apte à être actionné d'une position verrouillée vers une position déverrouillée pour permettre le déplacement de la gâchette vers la position inactive.The blocking pulley according to the invention is characterized in that the control means comprise a lock fixed on the first flange, and able to be actuated from a locked position to an unlocked position to allow the trigger to be moved to the position inactive.

Toute tentative de déplacement forcé de la gâchette dans le sens du déblocage est stoppée dans une position intermédiaire, laquelle est instable aussi longtemps que le verrou demeure dans la position verrouillée. Le déplacement poursuivi de la gâchette vers la position inactive stable est donc interdit. Le passage vers cette position inactive redevient possible dès que l'on appui sur le verrou.Any attempt to forcibly move the trigger in the unlocking direction is stopped in an intermediate position, which is unstable as long as the latch remains in the locked position. Continued movement of the trigger to the stable inactive position is therefore prohibited. The transition to this inactive position becomes possible once the lock is pressed.

Selon un mode de réalisation préférentiel, le verrou est pivotant autour d'un axe, et est sollicité vers la position verrouillée par un ressort de rappel. Le verrou comporte une encoche dans laquelle s'engage un téton de la gâchette pour autoriser le passage vers la position inactive.According to a preferred embodiment, the latch is pivotable about an axis, and is biased towards the locked position by a return spring. The lock has a notch in which engages a pin of the trigger to allow passage to the inactive position.

Selon une caractéristique de l'invention, le verrou est logé dans un plot fixé sur un premier flasque, lequel sert également de support au premier axe du galet et au deuxième axe de la gâchette.According to a feature of the invention, the latch is housed in a stud fixed on a first flange, which also serves as a support for the first axis of the roller and the second axis of the trigger.

Un deuxième flasque mobile est avantageusement monté à basculement sur l'extrémité du premier axe entre une position fermée et une position ouverte. Le premier flasque comporte un premier orifice circulaire situé près du deuxième axe de la gâchette et au-dessus du galet rotatif. Le deuxième flasque est pourvu d'un deuxième orifice circulaire venant en alignement en position fermée avec le premier orifice du premier flasque, en autorisant le passage d'un mousqueton d'attache.A second mobile flange is advantageously mounted to tilt over the end of the first axis between a closed position and an open position. The first flange has a first circular orifice located near the second axis of the trigger and above the rotary roller. The second flange is provided with a second circular orifice coming into alignment in closed position with the first port of the first flange, allowing the passage of a carabiner attachment.

Description détaillée de l'inventionDetailed description of the invention

Sur les figures, une poulie 10 comporte un premier flasque 11 fixe servant de support à un premier axe 12 d'un galet 13 rotatif, et un deuxième axe 14 de pivotement d'une gâchette 15 de blocage.In the figures, a pulley 10 comprises a first fixed flange 11 serving to support a first axis 12 of a rotary roller 13, and a second pivot axis 14 of a locking trigger 15.

Les deux axes 12, 14 sont fixes, et s'étendent parallèlement l'un à l'autre selon une direction perpendiculaire au premier flasque 11. Le galet 13 cylindrique est monté à rotation libre autour du premier axe 12, et est muni à sa périphérie d'une gorge 16 annulaire pour le guidage de la corde.The two axes 12, 14 are fixed, and extend parallel to each other in a direction perpendicular to the first flange 11. The cylindrical roller 13 is mounted to rotate freely about the first axis 12, and is provided with its periphery of an annular groove 16 for guiding the rope.

La gâchette 15 pivotante est pourvue d'une surface de freinage 17 destinée à presser la corde contre le galet 13 pour constituer un bloqueur intégré dans l'espace 18 entre les deux axes 12, 14. La surface de freinage 17 comporte une pluralité de picots inclinés destinés à renforcer l'effet de blocage de la corde lorsque le bloqueur est actif. Un ressort (non représenté) sollicite la gâchette 15 vers le galet 13.The pivoting trigger 15 is provided with a braking surface 17 for pressing the rope against the roller 13 to constitute a blocker integrated in the space 18 between the two shafts 12, 14. The braking surface 17 comprises a plurality of pins slanted to enhance the locking effect of the rope when the blocker is active. A spring (not shown) urges the trigger 15 towards the roller 13.

Un deuxième flasque 19 mobile est monté à basculement sur l'extrémité du premier axe 12 entre une position fermée et une position ouverte. La position ouverte du deuxième flasque 19 permet la mise en place de la corde, après avoir déplacé la gâchette 15 vers la position inactive, l'écartant du galet 13. Dans la position fermée du deuxième flasque 19, la corde est enroulée en boucle sur le galet 13, et est emprisonnée dans l'intervalle transversal ménagé entre les flasques 11, 19 parallèles.A second mobile flange 19 is tiltably mounted on the end of the first axis 12 between a closed position and an open position. The open position of the second flange 19 allows the establishment of the rope, after moving the trigger 15 to the inactive position, moving it away from the roller 13. In the closed position of the second flange 19, the rope is wound in a loop on the roller 13, and is trapped in the transverse gap formed between the flanges 11, 19 parallel.

Le premier flasque 11 comporte un premier orifice 20 circulaire situé près du deuxième axe 14, et au-dessus du galet 13 rotatif. Le deuxième flasque 19 est doté d'un deuxième orifice 21 circulaire, lequel vient en alignement avec le premier orifice 20 lorsque les deux flasques 11, 19 sont positionnés en position fermée. Il est alors possible d'y introduire un mousqueton d'attache pour maintenir les flasques 11, 19 dans cette position en empêchant tout basculement intempestif.The first flange 11 has a first circular orifice 20 located near the second axis 14, and above the rotating roller 13. The second flange 19 is provided with a second circular orifice 21, which comes into alignment with the first orifice 20 when the two flanges 11, 19 are positioned in the closed position. It is then possible to introduce a carabiner attachment to maintain the flanges 11, 19 in this position by preventing inadvertent tilting.

Au-dessus du premier orifice 20, se trouve un plot 22 fixé au premier flasque 11, en occupant l'intervalle transversal entre les flasques 11, 19. Le plot 22 est équipé d'un verrou 23 susceptible de pivoter autour d'un axe 24 entre une position verrouillée (figures 2, 4 et 5), et une position déverrouillée (figure 3). L'axe 24 de pivotement du verrou 23 est parallèle au deuxième axe 14 de la gâchette 15.Above the first orifice 20, is a stud 22 fixed to the first flange 11, occupying the transverse gap between the flanges 11, 19. The stud 22 is equipped with a latch 23 pivotable about an axis 24 between a locked position ( figures 2 , 4 and 5 ), and an unlocked position ( figure 3 ). The pivot axis 24 of the latch 23 is parallel to the second axis 14 of the trigger 15.

Le verrou 23 comprend une encoche 25 dans laquelle peut s'engager un téton 26 de la gâchette 15 pour assurer son blocage dans la position inactive de la figure 2. Un ressort 27 sollicite le verrou 23 vers la position relevée verrouillée. Dans cette position, le verrou 23 ne fait pas saillie du plot 22.The latch 23 comprises a notch 25 in which can engage a pin 26 of the trigger 15 to ensure its locking in the inactive position of the figure 2 . A spring 27 biases the latch 23 to the locked up position. In this position, the latch 23 does not project from the stud 22.

Le fonctionnement de la poulie 10 selon l'invention est le suivant :The operation of the pulley 10 according to the invention is as follows:

En référence aux figures 1 et 8, on fait basculer le deuxième flasque 19 vers la position ouverte pour la mise en place de la corde dans la gorge 16 à la partie supérieure du galet 13 rotatif. La gâchette 15 est maintenue en position inactive, c'est à dire écartée du galet 13, à l'encontre de la force antagoniste de son ressort de rappel.With reference to figures 1 and 8 the second flange 19 is tilted towards the open position for the positioning of the rope in the groove 16 at the upper part of the rotary roller 13. The trigger 15 is kept in the inactive position, that is to say spaced from the roller 13, against the counteracting force of its return spring.

La figure 2 montre la poulie 10 avec la gâchette 15 se trouvant dans la position inactive verrouillée. Le bloqueur n'est pas opérationnel, et le galet 13 est libre de tourner autour du premier axe 12. Le téton 26 est logé dans l'encoche 25 du verrou 23, lequel occupe la position verrouillée. Cette position de la gâchette 15 est stable.The figure 2 shows the pulley 10 with the trigger 15 in the locked inactive position. The blocker is not operational, and the roller 13 is free to rotate about the first axis 12. The stud 26 is housed in the notch 25 of the latch 23, which occupies the locked position. This position of the trigger 15 is stable.

La figure 3 représente la libération de la gâchette 15 après avoir appuyé sur le verrou 23 qui se déplace dans le plot 22 vers la position déverrouillée. Le pivotement du verrou 23 dans le sens inverse des aiguilles d'une montre, provoque le recul de l'encoche 25 et l'échappement du téton 26. La gâchette 15 se trouve dans la position inactive déverrouillée, laquelle est instable.The figure 3 represents the release of the trigger 15 after pressing the latch 23 which moves in the stud 22 to the unlocked position. The pivoting of the latch 23 in the counterclockwise direction causes the notch 25 to recoil and the pin 26 to escape. The trigger 15 is in the unlocked inactive position, which is unstable.

Sur la figure 4, le verrou 23 retourne vers la position verrouillée, après que le ressort de rappel a entrainé la gâchette 15 en direction du galet 13. La gâchette 15 se trouve dans la position active qui est stable. Le bloqueur peut ainsi bloquer la corde en cas de tension apparaissant sur le brin de gauche.On the figure 4 , the latch 23 returns to the locked position, after the return spring has pulled the trigger 15 towards the roller 13. The trigger 15 is in the active position which is stable. The blocker can thus lock the rope in case of tension appearing on the left strand.

Sur la figure 5, le verrou 23 est toujours en position verrouillée, et tout déplacement forcé de la gâchette 15 dans le sens du déblocage (flèche F) est stoppé dans une position intermédiaire lorsque le téton 26 vient en engagement contre une butée du verrou 23. Cette position est instable, et le maintien du verrou 23 dans la position verrouillée, interdit tout déplacement poursuivi de la gâchette 15 vers la position stable de la figure 2. Le passage vers cette position redevient possible dès que l'on appui sur le verrou 23.On the figure 5 , the latch 23 is always in the locked position, and any forced displacement of the trigger 15 in the unlocking direction (arrow F) is stopped in an intermediate position when the stud 26 comes into engagement with a stop of the latch 23. This position is unstable, and maintaining the latch 23 in the locked position, prohibits any continued movement of the trigger 15 to the stable position of the figure 2 . The passage to this position becomes possible once the latch 23 is pressed.
