Description

Domaine technique de l'inventionTechnical field of the invention

L'invention concerne un bloqueur de longe à corps mobile en rotation, et en particulier un bloqueur de longe destinée à attacher un élément à un point d'accrochage fixe.The invention relates to a lanyard locker with a body movable in rotation, and in particular a lanyard blocker for attaching an element to a fixed attachment point.

L'invention concerne notamment un bloqueur de longe destinée à assurer un utilisateur à une paroi fixe dans le domaine de l'alpinisme, l'escalade, la spéléologie, ou les travaux en hauteur.The invention particularly relates to a lanyard blocker for providing a user with a fixed wall in the field of mountaineering, climbing, caving, or work at height.

État de la techniqueState of the art

Actuellement, on peut utiliser une longe pour s'assurer à une paroi fixe. Une telle longe est constituée d'une corde pourvue généralement, à au moins une extrémité, d'un anneau d'accrochage, par exemple un mousqueton, pour s'assurer à un anneau fixé à la paroi, l'autre extrémité étant reliée au grimpeur. On peut en outre utiliser ces longes pour attacher tout type d'équipement. Mais la longueur de ces longes n'est pas réglable.Currently, a lanyard can be used to ensure a fixed wall. Such a lanyard consists of a rope generally provided, at at least one end, with a hooking ring, for example a carabiner, to ensure a ring fixed to the wall, the other end being connected to the climber. These lanyards can also be used to attach any type of equipment. But the length of these lanyards is not adjustable.

Il existe des bloqueurs de corde, tels des assureurs commercialisés par la société CAMP, utilisés pour assurer la progression ascensionnelle d'un grimpeur par une autre personne qui est au sol. Un tel bloqueur comprend un trou traversant pour le passage d'un mousqueton et une gorge débouchant dans le premier trou pour un passage de la corde dans le trou et à travers le mousqueton. Le mousqueton est par ailleurs attaché au baudrier de la personne au sol qui assure le grimpeur. La corde peut être bloquée en la coinçant entre le mousqueton et le bloqueur. Pour déloquer la corde, l'assureur approche les deux brins de la corde, l'un vers l'autre, et fait pivoter le bloqueur pour libérer le mousqueton et ainsi débloquer la corde. Mais lorsqu'on fait coulisser la corde pour donner du mou au grimpeur, la corde frotte contre le mousqueton, et entraîne une usure de celle-ci.There are rope blockers, such as insurers marketed by the company CAMP, used to ensure the ascension of a climber by another person who is on the ground. Such a blocker comprises a through hole for the passage of a carabiner and a groove opening into the first hole for a passage of the rope through the hole and through the carabiner. The carabiner is also attached to the harness of the person on the ground who assures the climber. The rope can be locked by wedging it between the carabiner and the blocker. To dislodge the rope, the insurer approaches the two strands of the rope, one towards the other, and rotates the blocker to release the carabiner and thus unlock the rope. But when the rope is slid to give slack to the climber, the rope rubs against the carabiner, and causes wear of it.

Objet de l'inventionObject of the invention

L'objet de l'invention consiste à remédier à ces inconvénients, et plus particulièrement à réaliser un bloqueur de longe simple et léger.The object of the invention is to overcome these disadvantages, and more particularly to achieve a simple and lightweight lanyard blocker.

Il est donc proposé un bloqueur de longe ayant un corps muni d'un trou traversant pour le passage d'un anneau d'accrochage et d'une gorge incurvée débouchant dans le trou traversant pour le passage de la longe à travers l'anneau, le corps étant mobile en rotation entre une position de blocage dans laquelle la longe est bloquée par l'anneau contre le corps et une position de déblocage dans laquelle la longe coulisse dans la gorge.It is therefore proposed a lanyard blocker having a body provided with a through hole for the passage of a hooking ring and a curved groove opening into the through hole for the passage of the lanyard through the ring, the body being movable in rotation between a locking position in which the lanyard is locked by the ring against the body and an unlocking position in which the lanyard slides in the groove.

La gorge comporte un élément de déviation pour permettre, en position de déblocage, un coulissement de la longe dans la gorge et à l'extérieur du trou traversant.The groove comprises a deflection element to allow, in unlocking position, a sliding of the lanyard in the groove and outside the through hole.

L'élément de déviation est une paroi séparant l'intérieur du trou traversant et l'intérieur de la gorge pour permettre, en position de déblocage, à l'anneau d'accrochage d'être en appui contre l'élément de déviation de façon que la longe coulisse sans frotter contre l'anneau d'accrochage.The deflection element is a wall separating the interior of the through-hole and the interior of the groove to allow, in the unlocking position, the fastening ring to bear against the deflection element so as to that the long slide without rubbing against the snap ring.

Un tel bloqueur permet un blocage de la longe efficace, tout en permettant de régler la longueur de la longe sous charge. En particulier, un tel bloqueur permet de faire coulisser la longe de façon qu'elle ne puisse pas frotter contre l'anneau d'accrochage, afin d'éviter une usure intempestive de la longe. Un tel bloqueur est particulièrement adapté pour s'assurer à un point fixe.Such a blocker allows a locking of the effective lanyard, while allowing to adjust the length of the lanyard under load. In particular, such a blocker makes it possible to slide the lanyard so that it can not rub against the snap ring, in order to avoid untimely wear of the lanyard. lanyard. Such a blocker is particularly suitable for making sure at a fixed point.

La gorge peut être configurée pour exercer des frottements sur la longe de façon à permettre un basculement du corps d'une position à l'autre.The groove can be configured to exert friction on the lanyard so as to allow the body to tilt from one position to the other.

La gorge peut comporter un premier orifice pour un passage de la longe à l'intérieur du corps, un deuxième orifice débouchant dans le trou traversant et un troisième orifice pour un passage de la longe à l'extérieur du corps, les premier et troisième orifices étant séparés par un élément de séparation du corps, l'élément de séparation permettant par effet de levier le passage du corps en position de déblocage lorsque la longe est en appui contre l'élément de séparation.The groove may comprise a first orifice for passage of the lanyard inside the body, a second orifice opening into the through hole and a third orifice for a passage of the lanyard outside the body, the first and third openings. being separated by a separating member of the body, the separating member allowing by leverage the passage of the body in the unlocking position when the lanyard bears against the separating element.

La gorge peut comporter en outre une ouverture orientée vers l'extérieur du corps et située entre les premier et deuxième orifices de la gorge.The groove may further comprise an opening facing outwardly of the body and located between the first and second orifices of the groove.

Une telle ouverture permet d'accéder à la portion de la longe qui passe dans la gorge afin, notamment, de faciliter le coulissement de la longe dans le corps du bloqueur.Such an opening allows access to the portion of the lanyard that passes into the groove, in particular to facilitate the sliding of the lanyard in the body of the blocker.

Le corps peut être muni d'une poulie située entre les premier et deuxième orifices de la gorge.The body may be provided with a pulley located between the first and second ports of the groove.

Le corps peut également comporter une poignée pour faciliter la rotation du corps.The body may also include a handle to facilitate rotation of the body.

La poignée peut comprendre au moins une portion recouvrant en partie le trou traversant de manière à être en appui contre l'anneau d'accrochage afin de diminuer l'effort dans la poignée grâce à un effet de démultiplication.The handle may comprise at least a portion partially covering the through hole so as to bear against the attachment ring to reduce the effort in the handle through a reduction effect.

Les deux brins de la longe peuvent être attachés à un même élément.The two strands of the lanyard can be attached to the same element.

Le corps peut être réalisé à partir d'une seule pièce, de préférence en métal, et par exemple en aluminium.The body can be made from a single piece, preferably metal, and for example aluminum.

Le corps peut également être réalisé à partir de deux tôles maintenues ensemble par des rivets.The body can also be made from two sheets held together by rivets.

Sur les figures 2 et 3, on a représenté schématiquement une vue antérieure du bloqueur 1 de longe 2 en position de déblocage. En particulier, la figure 3 est une vue en coupe selon l'axe A-A de la figure 1. On a également reporté sur les figures certaines références des éléments précédemment décrits à la figure 1. Le corps 3 du bloqueur 1 comporte en outre une gorge 9 pour guider la longe à l'intérieur du corps 3, de sorte que la longe 2 passe dans le trou traversant 4 et à travers le mousqueton 5. En particulier, la gorge 9 permet un coulissement de la longe 2 à l'extérieur du trou traversant 4, en d'autres termes autour du trou traversant 4. La gorge 9 comporte un premier orifice 11 pour un passage de la longe à l'intérieur du corps 3, un deuxième orifice 10 débouchant dans le trou traversant 4 et un troisième orifice 8 débouchant vers l'extérieur du corps 3. En outre, la gorge 9 comporte une portion 18 située entre les premier et deuxième orifices 11, 10 de la gorge 9. La portion 18 est incurvée en direction du trou traversant 4. De préférence, la gorge 9 a une forme globale en U. Le trou traversant 4 et les orifice 11, 10, 8 de la gorge 9 ont une forme globalement cylindrique. Le trou traversant 4 peut avoir une forme ovoïde. Le trou traversant 4 comporte un axe principal orienté sensiblement perpendiculairement au plan longitudinal du corps 3 (c'est-à-dire au plan de coupe selon l'axe A-A). Les premier, deuxième et troisième orifices 11, 10, 8 sont orientés, quant à eux, sensiblement perpendiculairement au trou traversant 4. Ainsi, la longe 2 entre dans le corps 3 en traversant le premier orifice 11, passe dans la portion incurvée 18 de la gorge 9, traverse le deuxième orifice 10, et passe à l'intérieur du trou traversant 4 selon une direction perpendiculaire à l'axe principal du trou traversant 4. Puis la longe 2 traverse le troisième orifice 8 de la gorge 9 pour sortir du corps 3 du bloqueur 1. La gorge 9 est orientée de manière que la longe 2 passe autour du trou traversant 4. En particulier, la portion incurvée 18 de la gorge 9 comporte un élément de déviation 12. De préférence, l'élément de déviation 12 peut être une paroi séparant l'intérieur du trou traversant 4 et l'intérieur de la portion incurvée 18 de la gorge 9. La paroi forme une surface d'appui 12 située entre la longe 2 et le mousqueton 5. En particulier, la surface d'appui 12 est située en regard de l'intérieur du trou traversant 4. Selon un mode de réalisation, la portion incurvée 18 peut être entièrement fermée au sein du corps 3 sur sa longueur et ouverte uniquement au niveau des premier et deuxième orifices 11, 10. Selon un autre mode de réalisation, la portion incurvée 18 de la gorge 9 peut comporter une ouverture 13 orientée vers l'extérieur du corps 3 pour accéder à longe 2, afin notamment de faciliter le coulissement de la longe 2 dans la gorge 9.On the Figures 2 and 3 , schematically shows an anterior view of the blocker 1 of lanyard 2 in the unlocking position. In particular, figure 3 is a sectional view along the axis AA of the figure 1 . Some references to the elements previously described in FIG. figure 1 . The body 3 of the blocker 1 further comprises a groove 9 to guide the lanyard inside the body 3, so that the lanyard 2 passes through the through hole 4 and through the carabiner 5. In particular, the groove 9 allows a sliding of the lanyard 2 outside the through hole 4, in other words around the through hole 4. The groove 9 has a first hole 11 for a passage of the lanyard inside the body 3, a second orifice 10 opening into the through hole 4 and a third orifice 8 opening towards the outside of the body 3. In addition, the groove 9 has a portion 18 located between the first and second orifices 11, 10 of the groove 9. The portion 18 is curved towards the through hole 4. Preferably, the groove 9 has a global shape in U. The through hole 4 and the openings 11, 10, 8 of the groove 9 have a generally cylindrical shape. The through hole 4 may have an ovoid shape. The through hole 4 comprises a main axis oriented substantially perpendicular to the longitudinal plane of the body 3 (that is to say, the cutting plane along the axis AA). The first, second and third ports 11, 10, 8 are oriented, in turn, substantially perpendicular to the through hole 4. Thus, the lanyard 2 enters the body 3 through the first orifice 11, passes into the curved portion 18 of the groove 9, passes through the second orifice 10, and passes inside the through hole 4 in a direction perpendicular to the main axis of the through hole 4. Then the lanyard 2 passes through the third orifice 8 of the groove 9 to exit the body 3 of the blocker 1. The groove 9 is oriented so that the lanyard 2 passes around the through hole 4. In particular, the curved portion 18 of the groove 9 comprises a deflection element 12. Preferably, the deflection element 12 may be a wall separating the interior of the through hole 4 and the inside of the curved portion 18 of the groove 9. The wall forms a bearing surface 12 located between the lanyard 2 and the carabiner 5. In particular, the support surface 12 is located opposite the interior of the through hole 4. According to one embodiment, the curved portion 18 can be fully closed within the body 3 along its length and open only at the first and second orifices 11, 10. Another embodiment, the curved portion 18 of the groove 9 may include an opening 13 facing outwardly of the body 3 to access to 2, in particular to facilitate the sliding of the lanyard 2 in the groove 9.

De manière générale, on peut noter que le troisième orifice 8 et le premier orifice 11 de la gorge 9 sont situés sur une même face du corps 3, et de part et d'autre du trou traversant 4. En outre, le corps 3 peut comprendre un élément de séparation 14 situé entre le troisième orifice 8 et le premier orifice 11 de la gorge 9. En variante, le corps 3 peut comprendre un orifice unique formant à la fois les premier et troisième orifices 11, 8 de la gorge 9. Dans cette variante, le corps 3 ne comprend pas un tel élément de séparation 14.In general, it may be noted that the third orifice 8 and the first orifice 11 of the groove 9 are situated on one and the same face of the body 3, and on either side of the through-hole 4. In addition, the body 3 can comprise a separation element 14 located between the third orifice 8 and the first orifice 11 of the groove 9. In a variant, the body 3 may comprise a single orifice forming both the first and third orifices 11, 8 of the groove 9. In this variant, the body 3 does not include such a separating element 14.

Le corps 3 du bloqueur 1 est mobile en rotation autour de l'axe principal du trou traversant 4, c'est-à-dire en rotation autour d'un axe de rotation sensiblement perpendiculaire au trou traversant 4. De manière générale, le corps 3 est mobile en rotation entre une position de blocage dans laquelle la longe 2 est bloquée par le mousqueton 5 contre le corps 3 et une position de déblocage dans laquelle la longe 2 coulisse dans la gorge 9.The body 3 of the blocker 1 is rotatable about the main axis of the through hole 4, that is to say in rotation about an axis of rotation substantially perpendicular to the through hole 4. In general, the body 3 is movable in rotation between a locking position in which the lanyard 2 is locked by the carabiner 5 against the body 3 and an unlocking position in which the lanyard 2 slides in the groove 9.

Dans la position de déblocage, la longe 2 coulisse dans la gorge 9 du corps 3 du bloqueur 1, en particulier dans la portion incurvée 18 de la gorge 9 et à travers le troisième orifice 8. Dans cette position, l'utilisateur peut faire coulisser la longe 2 en tirant sur l'un des brins 6, 7 de celle-ci. Le coulissement peut en outre être facilité par l'élément de déviation 12. En effet, lorsque le mousqueton 5 est en appui contre l'élément de déviation 12, l'utilisateur peut facilement faire coulisser la longe 2 en tirant uniquement sur le brin référencé 7, noté également brin mou. L'élément de déviation 12 permet, notamment, de faire coulisser la longe 2 lorsqu'un poids est fixé à l'extrémité de l'autre brin référencé 6, noté également brin de sécurité. En tirant sur le brin mou 7 on raccourci la longueur du brin de sécurité 6 entre le poids et le mousqueton 5. On peut également allonger la longueur du brin de sécurité 6, en relâchant la tension sur le brin mou 7, en maintenant le corps 3 dans la position de déblocage, et en tirant sur le brin de sécurité 6. On peut donc ainsi régler la longueur de la longe 2. En d'autres termes, on peut raccourcir la longueur du brin de sécurité 6 lorsqu'il est en tension, c'est-à-dire en charge, en tirant sur le brin mou 7. On peut allonger la longueur du brin de sécurité 6 lorsqu'il n'est plus en tension. On peut aussi régler les longueurs des deux brins 6, 7 de la longe 2, en enlevant le poids à chaque extrémité des brins 6, 7 de façon que chaque brin 6, 7 ne soit plus sous tension. En particulier, l'élément de déviation 12 permet le coulissement de la longe 2 tout en empêchant celle-ci de frotter contre le mousqueton 5.In the unblocking position, the lanyard 2 slides in the groove 9 of the body 3 of the blocker 1, in particular in the curved portion 18 of the groove 9 and through the third orifice 8. In this position, the user can slide the loin 2 pulling on one of the strands 6, 7 thereof. The sliding can also be facilitated by the deflection element 12. Indeed, when the carabiner 5 bears against the deflection element 12, the user can easily slide the lanyard 2 by pulling only on the referenced strand 7, also noted soft strand. The deflection element 12 allows, in particular, to slide the lanyard 2 when a weight is attached to the end of the other strand referenced 6, also noted safety strand. By pulling on the soft strand 7 the length of the safety strand 6 between the weight and the carabiner 5 is shortened. It is also possible to lengthen the length of the safety strand 6, releasing the tension on the soft strand 7, while maintaining the body 3 in the unlocking position, and by pulling the safety strand 6. It is thus possible to adjust the length of the lanyard 2. In other words, it can shorten the length of the safety strand 6 when it is in tension , that is to say in load, by pulling on the soft strand 7. The length of the safety strand 6 can be lengthened when it is no longer in tension. The lengths of the two strands 6, 7 of the loin 2 can also be adjusted by removing the weight at each end of the strands 6, 7 so that each strand 6, 7 is no longer under tension. In particular, the deflection element 12 makes it possible to slide the lanyard 2 while preventing it from rubbing against the carabiner 5.

Sur les figures 4 et 5, on a représenté schématiquement une vue antérieure du bloqueur 1 de longe 2 en position de blocage. En particulier, la figure 5 est une vue en coupe selon l'axe A-A de la figure 1. On a également reporté sur les figures certaines références des éléments décrits aux figures précédentes. Dans la position de blocage, le mousqueton 5 coince la longe 2 contre le corps 3 du bloqueur 1, en particulier contre un bord du trou traversant 4 qui est situé entre le troisième orifice 8 et le deuxième orifice 10 de la gorge 9. Par ailleurs, le mousqueton 5 est situé en regard de l'élément de déviation 12 et n'est pas en appui contre celui-ci. Dans la position de blocage, la longe 2 ne coulisse pas, et le brin de sécurité 6 est en tension et assure un accrochage d'un objet à l'anneau d'ancrage en toute sécurité. En outre, le brin mou 7 peut être fixé ou non à l'objet, car ce dernier n'est pas mis en tension.On the Figures 4 and 5 , schematically shows an anterior view of the blocker 1 of lanyard 2 in the locking position. In particular, figure 5 is a sectional view along the axis AA of the figure 1 . Some references to the elements described in the preceding figures have also been shown in the figures. In the locking position, the carabiner 5 wedges the lanyard 2 against the body 3 of the blocker 1, in particular against an edge of the through hole 4 which is situated between the third orifice 8 and the second orifice 10 of the groove 9. Moreover, the carabiner 5 is located facing the deflection element 12 and does not bear against it. In the locking position, the lanyard 2 does not slide, and the safety strand 6 is in tension and ensures an attachment of an object to the anchor ring safely. In addition, the soft strand 7 may or may not be attached to the object because the latter is not put in tension.

La rotation du corps 3 du bloqueur 1 permet le passage entre la position de blocage et la position de déblocage et inversement. Pour passer de la position de blocage à la position de déblocage, l'utilisateur tire sur le brin mou 7 de la longe 2, et le corps 3 bascule en prenant appui contre le mousqueton 5 au niveau de l'élément de déviation 12. Le corps 3 tourne autour de son axe de rotation jusqu'à la position de déblocage dans laquelle le mousqueton 5 est en appui contre l'élément de déviation 12 et ne coince plus la longe 2 contre le corps 3. La rotation du corps 3 libère le mousqueton 5 qui n'est plus en contact avec la longe 2. Ainsi, en position de déblocage, la longe 2 coulisse sans frotter contre le mousqueton 5, ce qui limite l'usure de la longe 2. La rotation du corps 3 pour passer en position de déblocage peut être réalisée en pleine charge, c'est-à-dire avec le brin de sécurité 6 en tension. En outre, la gorge 9 crée une chicane pour la longe 2, et génère des frottements sur la longe 2 afin de faciliter la rotation du corps 3 d'une position à l'autre. En particulier, l'élément de déviation 12 permet un premier effet de levier qui coopère avec la friction générée par la gorge 9 sur la longe 2, afin de faciliter le basculement du corps 3 en position de blocage. Par ailleurs, l'élément de séparation 14 favorise le passage en position de déblocage en permettant un appui du brin mou 7 sur l'élément de séparation 14 pour créer un deuxième effet de levier inverse au premier.The rotation of the body 3 of the blocker 1 allows the passage between the locking position and the unlocking position and vice versa. To pass from the blocking position to the unlocking position, the user pulls on the soft strand 7 of the lanyard 2, and the body 3 tilts while bearing against the carabiner 5 at the deflection element 12. 3 rotates about its axis of rotation to the unlocking position in which the carabiner 5 is in abutment against the deflection element 12 and does not wedge the longer the lanyard 2 against the body 3. The rotation of the body 3 releases the carabiner 5 which is no longer in contact with the lanyard 2. Thus, in the release position, the lanyard 2 slides without rubbing against the carabiner 5, which limit the wear of the lanyard 2. The rotation of the body 3 to move to the unlocking position can be performed under full load, that is to say with the safety strand 6 in tension. In addition, the groove 9 creates a baffle for the lanyard 2, and generates friction on the lanyard 2 to facilitate the rotation of the body 3 from one position to another. In particular, the deflection element 12 allows a first lever effect which cooperates with the friction generated by the groove 9 on the lanyard 2, to facilitate the tilting of the body 3 in the locking position. Furthermore, the separating element 14 facilitates the passage into the unlocking position by allowing the soft strand 7 to be supported on the separating element 14 to create a second inverse lever effect to the first.

Pour passer de la position de déblocage à la position de blocage, l'utilisateur relâche le brin mou 7 de la longe 2, et tire sur le brin de sécurité 6. Ainsi, le corps 3 bascule automatiquement en prenant appui contre le mousqueton 5, au niveau de l'élément de déviation 12 de la gorge 9, par l'effet du poids qui maintient en tension le brin de sécurité 6. Le corps 3 tourne autour de son axe de rotation jusqu'à la position de blocage dans laquelle le mousqueton 5 est en appui contre la longe 2 et coince celle-ci contre le corps 3.To pass from the unlocking position to the locking position, the user releases the soft strand 7 of the lanyard 2, and pulls on the safety strand 6. Thus, the body 3 automatically topples while bearing against the carabiner 5, at the deflection element 12 of the groove 9, by the effect of the weight which keeps the safety strand 6 in tension. The body 3 rotates about its axis of rotation to the locking position in which the carabiner 5 is in support against the loin 2 and wedges it against the body 3.

Sur la figure 6, on a représenté schématiquement une vue postérieure d'un bloqueur 1 de longe selon un autre mode de réalisation. Dans cet autre mode de réalisation, le corps 3 comporte une poulie 15 située dans la gorge 9, en particulier dans la portion incurvée 18, afin de faciliter le coulissement de la longe 2.On the figure 6 schematically a posterior view of a lanyard blocker 1 according to another embodiment. In this other embodiment, the body 3 comprises a pulley 15 located in the groove 9, in particular in the curved portion 18, in order to facilitate the sliding of the lanyard 2.

Les figures 7 et 8 illustrent de façon schématique des vues antérieures d'autres modes de réalisation d'un bloqueur 1 de longe 2. Selon un mode de réalisation illustré à la figure 8, le bloqueur 1 comporte une poignée 16 en saillie du corps 3 afin de faciliter sa rotation. Préférentiellement, la poignée 16 est située du côté du troisième orifice 8, c'est-à-dire du côté du brin mou 7. Selon un autre mode de réalisation, illustré à la figure 7, la poignée 16 comporte une portion 17 qui recouvre en partie le trou traversant 4 de manière à être en appui contre le mousqueton 5 pour démultiplier les efforts appliqués sur le mousqueton 5 par le corps 3 lors de la rotation de ce dernier.The Figures 7 and 8 schematically illustrate earlier views of other embodiments of a lanyard blocker 1. According to an embodiment illustrated in FIG. figure 8 , the blocker 1 has a handle 16 in protruding body 3 to facilitate its rotation. Preferably, the handle 16 is located on the side of the third orifice 8, that is to say on the side of the soft strand 7. According to another embodiment, illustrated in FIG. figure 7 , the handle 16 comprises a portion 17 which partially covers the through hole 4 so as to bear against the carabiner 5 to increase the forces applied to the carabiner 5 by the body 3 during the rotation of the latter.

On a également illustré aux figures 9 et 10 un autre mode de réalisation d'un bloqueur 1 de longe selon l'invention. Dans cet autre mode de réalisation, le corps 3 du bloqueur est réalisé à partir de deux tôles 3a, 3b maintenues ensemble par des rivets 12, 14, 20 à 23. Par exemple, le corps 3 peut comprendre deux rivets 20, 21 situés respectivement aux extrémités du corps 3. En particulier le rivet référencé 12 forme l'élément de déviation. Dans ce cas l'élément de déviation 12 peut être une tige globalement cylindrique. Par exemple le corps 3 peut comprendre un rivet référencé 14 formant l'élément de séparation. En outre, la gorge 9 peut comprendre une ouverture supplémentaire 24 pour une communication entre l'intérieur du trou traversant 4 et l'intérieur de la gorge 9. L'ouverture supplémentaire 24 est située entre l'élément de déviation 12 et l'élément de séparation 14.We also illustrated Figures 9 and 10 another embodiment of a lanyard blocker 1 according to the invention. In this other embodiment, the body 3 of the blocker is made from two sheets 3a, 3b held together by rivets 12, 14, 20 to 23. For example, the body 3 may comprise two rivets 20, 21 respectively at the ends of the body 3. In particular the rivet referenced 12 forms the deflection element. In this case the deflection element 12 may be a generally cylindrical rod. For example the body 3 may comprise a rivet referenced 14 forming the separating element. In addition, the groove 9 may comprise an additional opening 24 for communication between the interior of the through hole 4 and the inside of the groove 9. The additional opening 24 is located between the deflection element 12 and the element separation 14.

Ainsi, on fournit un bloqueur de longe réglable configuré pour accrocher tout type d'objet à un point fixe tout en permettant de régler la longueur de la longe. Un tel bloqueur est simple à utiliser et est particulièrement compact.Thus, there is provided an adjustable tether locker configured to hook any type of object to a fixed point while allowing the length of the lanyard to be adjusted. Such a blocker is simple to use and is particularly compact.
