In the event of a fall, which corresponds to a descent speed accelerated, the mobile fall arrester hangs on the cable.
- the user (8) can then climb or descend along the pylon (7) by letting the fall arrester slide up (HA) or down (BA) the along the safety cable (6), if necessary, while it will be ensured do not fall down by blocking its fall arrester (1) on said cable (6) constituting the belay support.
- the fall arrester (1) essentially comprises a hollow profile (9) straight intended to receive the belay cable (6) which is retained there after engagement, thanks to a pivotally movable cam (10).
- the profile hollow (9) is constituted by the wall (11a) of a main flange (12a) whose first side border (13a) is folded parallel to said wall, so as to form a gutter or a semi-circular groove (9), while the second lateral border (14a) is in the plane of the wall and is curved to include a clearance at the bottom (15a).
- the groove has a semi-circular profile with a vertical axis (YY ') and has substantially the dimension of the cable intended to be housed there.

Abstract
Description
La présente invention concerne un dispositif de sécurité du levier pivotant individuel contre les chutes en hauteur. Elle est relative à un antichute mobile pour support d'assurage plus particulièrement adapté aux supports d'assurage verticaux, notamment flexibles, tels que des câbles ou cordes.The present invention relates to a safety device for the pivoting lever individual against falls from a height. It relates to a fall arrest system mobile for belay support more particularly adapted to supports vertical belay devices, in particular flexible belay devices, such as cables or ropes.
Le personnel qui est amené à intervenir sur des installations en hauteur et qui doit à cet effet grimper ou descendre le long de pylônes ou de poteaux doit être assuré afin de ne pas chuter intempestivement. C'est, par exemple, le cas des installateurs ou des réparateurs d'installations comme, par exemple, des installations de téléphériques ou télésièges. Il est donc nécessaire de les assurer afin qu'ils puissent monter ou descendre en toute liberté, et ce, sans risque de chuter.The personnel who have to intervene on installations in height and which for this purpose must climb or descend along pylons or posts must be insured so as not to fall unexpectedly. It is, for example, the case of installers or repairers of installations such as, for example, cable car or chairlift installations. he is therefore necessary to insure them so that they can climb or descend freely, without the risk of falling.
On connaít déjà de tels dispositifs constitués par une corde ou un câble d'assurage disposé verticalement, appelé encore "ligne de vie", auquel l'utilisateur se relie de façon à pouvoir se déplacer vers le haut ou vers le bas. A cet effet, il est équipé d'un équipement de protection individuel le reliant à la "ligne de vie" et comprenant un harnais fixé à un antichute mobile. On connait par le document FR A 2 144 623 un antichute présentant une gorge de retenue dans laquelle coulisse un cable, qui peut être verrouillé à l'aide d'une came solidaire d'un levier pivotant entre une position d'ouverture et de fermeture. Par ailleurs, le document FR-A.2.668.937 divulgue un antichute pourvu d'un mécanisme rendant le dégagement accidentel du cable impossible. Toutefois, les dispositifs connus ne sont pas entièrement satisfaisants sur le plan de leur commodité d'utilisation et de leur fiabilité.We already know such devices consisting of a rope or a belay cable arranged vertically, also called "lifeline", to which the user connects so that he can move up or down. For this purpose, it is equipped with protective equipment individual connecting it to the "lifeline" and including a harness attached to a mobile fall arrester. Document FR A 2 144 623 discloses a fall arrester having a retaining groove in which a cable slides, which can be locked using a cam secured to a pivoting lever between an open and closed position. . Furthermore, document FR-A.2.668.937 discloses a fall arrester provided with a mechanism making accidental release of the cable impossible. However, the known devices are not fully satisfactory in terms of their ease of use and their reliability.
La présente invention propose un nouveau dispositif particulièrement sûr, fiable et commode à mettre en oeuvre.The present invention provides a new device particularly safe, reliable and convenient to use.
Ainsi, selon l'invention, l'antichute mobile pour support d'assurage tel qu'un câble ou une corde, est du type comprenant une gorge de retenue d'axe, dans laquelle est retenu ledit support d'assurage grâce à une came, solidaire d'un levier pivotant entre une position d'ouverture qui permet le passage du support d'assurage dans la gorge et une position de fermeture, qui limite le passage du support d'assurage dans la gorge caractérisé en ce que l'extrémité libre du levier pivotant comprend un trou destiné à recevoir un mousqueton, tandis qu'un système de butée pour le mousqueton limite le pivotement du levier dans une position intermédiaire quand on passe de la positon de fermeture vers la position d'ouverture lorsque le mousqueton est engagé dans le trou.Thus, according to the invention, the mobile fall arrester for support belay device such as a cable or rope, is of the type comprising a axis retaining groove, in which said belay support is retained thanks to a cam, integral with a pivoting lever between an open position which allows the passage of the belay support in the groove and a position of closure, which limits the passage of the belay support in the groove, characterized in that the free end of the pivoting lever comprises a hole intended to receive a carabiner, while a stop system for the carabiner limits the pivoting of the lever in an intermediate position when passing from the closed position to the open position when the carabiner is engaged in the hole.
Selon une disposition préférée, la gorge de retenue est réalisée par la paroi d'un flasque principal, tandis que l'antichute comprend un flasque secondaire constitué par une paroi, le levier étant monté pivotant entre les deux flasques.According to a preferred arrangement, the retaining groove is produced through the wall of a main flange, while the fall arrester includes a secondary flange constituted by a wall, the lever being pivotally mounted between the two flanges.
Selon une caractéristique complémentaire de l'invention, il est prévu un passage longitudinal et parallèle à l'axe de la gorge, ledit passage étant limité latéralement par, d'une part, la première bordure du flasque principal et, d'autre part, la première bordure du deuxième flasque.According to an additional characteristic of the invention, it is provided a longitudinal and parallel passage to the axis of the groove, said passage being limited laterally by, on the one hand, the first border of the main flange and, on the other hand, the first border of the second flaccid.
Selon une autre caractéristique complémentaire, les deuxièmes bordures comprennent un dégagement permettant le déplacement du levier avec son mousqueton et délimitant les butées définissant la position intermédiaire du levier.According to another additional characteristic, the second borders include a clearance allowing the movement of the lever with its carabiner and delimiting the stops defining the intermediate position of the lever.
Dans un mode d'exécution préféré, donné à titre d'exemple, la deuxième bordure latérale de chacun des flasques comprend une succession de deux rampes, une rampe inférieure en retrait par rapport à une rampe supérieure pour former le dégagement. La rampe inférieure est circulaire de rayon centré sur l'axe, tandis que la rampe supérieure est circulaire de rayon centré sur l'axe, sachant que le rayon de ladite rampe supérieure est supérieur au rayon de ladite rampe inférieure, le dégagement formé par la rampe inférieure en retrait, est limité vers le haut par les butées disposées radialement et sensiblement dans le plan horizontal passant par l'axe de pivotement du levier.In a preferred embodiment, given by way of example, the second side border of each of the flanges includes a succession of two ramps, a lower ramp set back from an upper ramp to form the clearance. The lower ramp is circular radius centered on the axis, while the upper ramp is circular radius centered on the axis, knowing that the radius of said ramp upper is greater than the radius of said lower ramp, the clearance formed by the lower recessed ramp, is limited towards the high by the stops arranged radially and substantially in the plane horizontal passing through the pivot axis of the lever.
Selon d'autres caractéristiques complémentaires de l'invention, la came du levier est constituée par une rampe de blocage prolongée par une rampe de déblocage, tandis que la largeur du levier est telle qu'il fait saillie au-delà des rampes supérieures quand le levier est en position d'ouverture extrême. According to other additional features of the invention, the lever cam consists of a locking ramp extended by a release ramp, while the width of the lever is such that it does protrudes beyond the upper ramps when the lever is in position of extreme opening.
D'autres caractéristiques et avantages de l'invention se dégageront de la description qui va suivre en regard des dessins annexés qui ne sont donnés qu'à titre d'exemples non limitatifsOther characteristics and advantages of the invention are will emerge from the description which will follow with regard to the appended drawings which are only given as nonlimiting examples

La figure 14 est une vue similaire à la figure 5 représentant une variante d'exécution avec une coupe partielle selon l'axe de pivotement du levier.Figure 14 is a view similar to Figure 5 showing a variant with partial cut along the pivot axis lever.
Les figures 15, 16 et 17 illustrent une variante d'exécution, les figures 15 et 16 étant des vues similaires aux figures 3 et 6.Figures 15, 16 and 17 illustrate an alternative embodiment, the Figures 15 and 16 being views similar to Figures 3 and 6.
L'antichute mobile (1) fait partie d'un équipement de protection individuel contre les chutes en hauteur portant la référence générale (2) et comprenant en plus dudit antichute (1) un harnais (3) portant au moins une boucle d'amarrage (4) avec un mousqueton d'accrochage (5), ledit antichute (2) étant destiné à être connecté de façon amovible sur un support d'assurage (6) vertical fixé, par exemple, sur un pylône d'intervention (7).The mobile fall arrester (1) is part of protective equipment individual against falls from a height with the general reference (2) and comprising in addition to said fall arrester (1) a harness (3) carrying the minus a mooring loop (4) with a snap hook (5), said fall arrester (2) being intended to be removably connected to a vertical belay support (6) fixed, for example, on a pylon intervention (7).
Dans sa position d'utilisation, c'est-à-dire relié au harnais (3), l'antichute mobile (1) peut être à volonté déplacé vers le haut (HA) ou vers le bas (BA) par coulissement normal (c'est-à-dire à la vitesse d'ascension ou de descente de l'utilisateur) le long du câble vertical (6) constituant le support d'assurage qui peut, par ailleurs, être constitué par une corde. En cas de chute, ce qui correspond à une vitesse de descente accélérée, l'antichute mobile se bloque sur le câble. On comprendra que l'utilisateur (8) pourra alors grimper ou descendre le long du pylône (7) en laissant coulisser l'antichute vers le haut (HA) ou vers le bas (BA) le long du câble de sécurité (6), en cas de besoin, tandis qu'il sera assuré de ne pas chuter vers le bas par blocage de son antichute (1) sur ledit câble (6) constituant le support d'assurage.In its position of use, that is to say connected to the harness (3), the mobile fall arrester (1) can be moved upwards (HA) or down (BA) by normal sliding (i.e. at speed user ascending or descending) along the vertical cable (6) constituting the belay support which can, moreover, be constituted by a rope. In the event of a fall, which corresponds to a descent speed accelerated, the mobile fall arrester hangs on the cable. We will understand that the user (8) can then climb or descend along the pylon (7) by letting the fall arrester slide up (HA) or down (BA) the along the safety cable (6), if necessary, while it will be ensured do not fall down by blocking its fall arrester (1) on said cable (6) constituting the belay support.
L'antichute (1) comprend essentiellement un profil en creux (9) rectiligne destiné à recevoir le câble d'assurage (6) qui y est retenu après engagement, grâce à une came (10) mobile en pivotement. Ainsi, le profil en creux (9) est constitué par la paroi (11a) d'un flasque principal (12a) dont la première bordure latérale (13a) est repliée parallèlement à ladite paroi, de façon à former une gouttière ou une gorge semi-circulaire (9), tandis que la deuxième bordure latérale (14a) est dans le plan de la paroi et est courbe pour comprendre à sa partie inférieure un dégagement (15a). Notons que la gorge a un profil semi-circulaire d'axe vertical (YY') et a sensiblement la dimension du câble destiné à venir s'y loger. Par ailleurs, la came de blocage (10) est solidaire d'un levier de manoeuvre et d'accrochage (16) qui est monté mobile en pivotement sur l'antichute autour d'un axe transversal (XX').The fall arrester (1) essentially comprises a hollow profile (9) straight intended to receive the belay cable (6) which is retained there after engagement, thanks to a pivotally movable cam (10). So the profile hollow (9) is constituted by the wall (11a) of a main flange (12a) whose first side border (13a) is folded parallel to said wall, so as to form a gutter or a semi-circular groove (9), while the second lateral border (14a) is in the plane of the wall and is curved to include a clearance at the bottom (15a). Note that the groove has a semi-circular profile with a vertical axis (YY ') and has substantially the dimension of the cable intended to be housed there. Through elsewhere, the locking cam (10) is integral with an operating lever and hook (16) which is pivotally mounted on the fall arrester around a transverse axis (XX ').
Notons que la deuxième bordure latérale (14a) comprend une succession de deux rampes, une rampe inférieure (17a) en retrait par rapport à une rampe supérieure (18a) pour former le dégagement (15a). La rampe inférieure est circulaire de rayon (R1) centré sur l'axe (XX'), tandis que la rampe supérieure est circulaire de rayon (R2) centré sur l'axe (XX') sachant que le rayon (R2) de ladite rampe supérieure est supérieur au rayon (R1) de ladite rampe inférieure. Par ailleurs, le dégagement (15a) dont on expliquera la fonction plus loin dans la description, formé par la rampe inférieure en retrait, est limité vers le haut par une butée (20a) disposée radialement et sensiblement dans le plan horizontal (H) passant par l'axe (XX') de pivotement du levier (16).Note that the second side border (14a) includes a succession of two ramps, a lower ramp (17a) set back by relative to an upper ramp (18a) to form the clearance (15a). The lower ramp is circular with radius (R1) centered on the axis (XX '), while the upper ramp is circular with radius (R2) centered on the axis (XX ') knowing that the radius (R2) of said upper ramp is greater than the radius (R1) of said lower ramp. In addition, the clearance (15a) whose function will be explained later in the description, formed by the lower recessed ramp, is limited to the high by a stop (20a) arranged radially and substantially in the horizontal plane (H) passing through the pivot axis (XX ') of the lever (16).
Le corps de l'antichute mobile comprend, en plus du flasque principal (12a) décrit précédemment et formant la gorge (9), un flasque secondaire (12b). Ce dernier est solidaire du flasque principal pour lui être parallèle et espacé d'une distance (d) pour constituer, d'une part, un espace (e) entre les deux flasques destinés au déplacement du levier (16) et, d'autre part, un passage longitudinal (40) pour l'engagement du câble (40). Le flasque secondaire a une configuration identique à la paroi (11a) du flasque principal (12a). Ainsi, il est constitué par une paroi (11b) et comprend une première bordure latérale (13b) rectiligne, tandis que la deuxième bordure latérale (14b) est dans le plan de la paroi et est courbe pour comprendre à sa partie inférieure un dégagement (15b). Ainsi, la deuxième bordure latérale (14b) comprend une succession de deux rampes, une rampe inférieure (17b) en retrait par rapport à une rampe supérieure (18b) pour former le dégagement (15b). La rampe inférieure est circulaire de rayon (R1) centré sur l'axe (XX'), tandis que la rampe supérieure est circulaire de rayon (R2) centré sur l'axe (XX'), sachant que le rayon (R2) de ladite rampe supérieure est supérieur au rayon (R1) de ladite rampe inférieure. Par ailleurs, le dégagement (15b) dont on expliquera la fonction plus loin dans la description, formé par la rampe inférieure en retrait, est limité vers le haut par une butée (20b) disposée radialement et sensiblement dans le plan horizontal (H) passant par l'axe (XX') de pivotement du levier (16). Ajoutons que le passage (40) est limité latéralement par la première bordure (13a) du flasque principal (12a) et la première bordure (13b) du flasque secondaire (12b). Bien entendu, la largeur du passage est supérieure au diamètre du câble (6) destiné à y être engagé, ledit passage s'étendant parallèlement à l'axe (YY') de la gorge.The body of the mobile fall arrester includes, in addition to the flange main (12a) described above and forming the groove (9), a flange secondary (12b). The latter is integral with the main flange for him be parallel and spaced by a distance (d) to constitute, on the one hand, a space (e) between the two flanges intended for the movement of the lever (16) and, on the other hand, a longitudinal passage (40) for the engagement of the cable (40). The secondary flange has a configuration identical to the wall (11a) of the main flange (12a). Thus, it is constituted by a wall (11b) and comprises a first rectilinear side border (13b), while the second lateral border (14b) is in the plane of the wall and is curved to understand at its lower part a clearance (15b). So the second side border (14b) comprises a succession of two ramps, a lower ramp (17b) set back from a ramp upper (18b) to form the clearance (15b). The lower ramp is circular with radius (R1) centered on the axis (XX '), while the ramp upper is circular with radius (R2) centered on the axis (XX '), knowing that the radius (R2) of said upper ramp is greater than the radius (R1) of said lower ramp. Furthermore, the clearance (15b) which is will explain the function later in the description, formed by the ramp lower set back, is limited upwards by a stop (20b) arranged radially and substantially in the horizontal plane (H) passing through the axis (XX ') pivoting of the lever (16). Add that the passage (40) is laterally limited by the first border (13a) of the main flange (12a) and the first border (13b) of the secondary flange (12b). Well of course, the width of the passage is greater than the diameter of the cable (6) intended to be engaged therein, said passage extending parallel to the axis (YY ') of the throat.
Le levier (16) précédemment évoqué est disposé mobile en pivotement autour de l'axe (XX'). Il est disposé pour se déplacer entre les deux flasques (12a, 12b), dans l'espace (e) formé entre le flasque principal (12a) et le flasque secondaire (12b). Il est ainsi monté en rotation autour d'un axe (21) s'étendant entre les deux flasques pour que son extrémité d'accrochage (22) s'étende au-delà des rampes inférieures (17a, 17b) des deux flasques (12a, 12b), dans la zone créée par les dégagements (15a, 15b). Ladite extrémité libre d'accrochage (22) comprend de plus un trou d'accrochage (23) destiné à recevoir le mousqueton d'accrochage (5) qui peut y être engagé grâce au dégagement (15a, 15b) prévu sur les bordures des flasques (12a, 12b). Le trou d'accrochage (23) est cylindrique et son axe (QQ') est à une distance (L1) de l'axe (XX') comprise entre la valeur du rayon (R1) de la rampe inférieure (17a, 17b) et la valeur du rayon (R2) de la rampe supérieure (18a, 18b). De plus, son diamètre est tel que sa paroi périphérique (24) soit à une distance (L2) de l'axe (XX') supérieur au rayon (R2).The lever (16) previously mentioned is disposed movable in pivot around the axis (XX '). It is arranged to move between the two flanges (12a, 12b), in the space (e) formed between the main flange (12a) and the secondary flange (12b). It is thus rotatably mounted around an axis (21) extending between the two flanges so that its end attachment (22) extends beyond the lower ramps (17a, 17b) of two flanges (12a, 12b), in the area created by the clearances (15a, 15b). Said free hooking end (22) further comprises a hole hook (23) for receiving the snap hook (5) which can be engaged thanks to the clearance (15a, 15b) provided on the edges flanges (12a, 12b). The hanging hole (23) is cylindrical and its axis (QQ ') is at a distance (L1) from the axis (XX') between the value of the radius (R1) of the lower ramp (17a, 17b) and the value of the radius (R2) of the upper ramp (18a, 18b). In addition, its diameter is such that its peripheral wall (24) either at a distance (L2) from the upper axis (XX ') to the radius (R2).
Par ailleurs, le levier (16) comprend du côté opposé au trou d'accrochage (23) une came (10) constituée par une rampe de blocage (25) pour assurer le blocage de l'antichute (1) sur le câble d'assurage prolongé par une rampe de déblocage (26) de l'antichute permettant le coulissement dudit antichute sur ledit câble d'assurage (6). Le levier (16) pouvant prendre par rotation autour de l'axe (XX') deux positions extrêmes, une position d'ouverture tel qu'illustré aux figures 6 et 8, et une position de fermeture tel que représenté aux figures 3, 10, 11 et 12.Furthermore, the lever (16) comprises on the side opposite the hole hooking (23) a cam (10) constituted by a locking ramp (25) to block the fall arrester (1) on the belay cable extended by a ramp for unlocking (26) the fall arrester allowing the sliding of said fall arrester on said belay cable (6). The lever (16) can be rotated around the axis (XX ') two positions extremes, an open position as illustrated in FIGS. 6 and 8, and a closed position as shown in Figures 3, 10, 11 and 12.
Notons que le levier est constamment sollicité vers sa position de fermeture par un ressort de torsion (27). Ce dernier est utile, d'une part, au maintien en place de l'antichute (1) sur le câble d'assurage (6) au moment de la mise en place et du retrait du mousqueton (5) et, d'autre part, pour assurer un blocage de l'antichute en cas de chute, et ce, avant même que le mousqueton (5) n'ait à assurer à lui seul le pivotement du levier vers le bas. Ajoutons que l'antichute comprend deux butées (28, 29) pour limiter le déplacement angulaire du levier vers le bas par une butée inférieure (28) et vers le haut par une butée supérieure (29). La butée inférieure (28) est réalisée par une petite paroi transversale (30) s'étendant entre les deux flasques (12a, 12b) dans la zone des rampes inférieures (17a, 17b), tandis que la butée supérieure (29) est réalisée par une entretoise cylindrique supérieure reliant la position supérieure des deux flasques (12a, 12b). Note that the lever is constantly biased towards its position of closing with a torsion spring (27). The latter is useful, on the one hand, maintaining the fall arrester (1) on the belay cable (6) at moment of fitting and removing the carabiner (5) and, on the other part, to ensure that the fall arrester is locked in the event of a fall, before even that the carabiner (5) does not have to ensure by itself the pivoting of the lever down. Add that the fall arrester has two stops (28, 29) to limit the angular movement of the lever downwards by a stop lower (28) and upwards by an upper stop (29). Stop lower (28) is produced by a small transverse wall (30) extending between the two flanges (12a, 12b) in the area of the ramps lower (17a, 17b), while the upper stop (29) is produced by an upper cylindrical spacer connecting the upper position of the two flanges (12a, 12b).
Les figures 8 à 12 illustrent les différentes étapes de mise en place de l'antichute de l'invention. L'utilisateur en posant le premier flasque (12a) de l'antichute (1) dans la paume de la main droite fait pivoter avec son pouce le levier (16) vers le haut selon R1 pour dégager le passage (40) pour le câble. Il amène l'antichute (1) sur le câble (6) pour faire passer ledit câble (6) pour le passage (40), comme cela est illustré à la figure 8. Puis il engage le câble (6) dans la gorge (9) et libère le levier (16), comme cela est illustré à la figure 9. Le levier (16) sollicité par le ressort (27) pivote vers le bas selon (R2) jusqu'à ce que la rampe de blocage (25) vienne pincer le câble en le retenant ainsi dans la gorge (9), comme cela est représenté à la figure 10.Figures 8 to 12 illustrate the different stages of implementation of the fall arrest device of the invention. The user by putting the first flange (12a) of the fall arrester (1) in the palm of the right hand rotate with his thumb the lever (16) upwards along R1 to clear the passage (40) for the cable. He brings the fall arrester (1) on the cable (6) to make pass said cable (6) for passage (40), as illustrated in the figure 8. Then he engages the cable (6) in the groove (9) and releases the lever (16), as illustrated in FIG. 9. The lever (16) urged by the spring (27) pivots downwards along (R2) until the ramp blocking (25) pinch the cable, thus retaining it in the groove (9), as shown in Figure 10.
L'utilisateur installe alors un mousqueton (5) en l'engageant dans le trou (23) du levier (16), tel qu'illustré à la figure 11. Ensuite, il fixe son harnais (3) au mousqueton, par exemple, par l'intermédiaire des boucles d'amarrage (4), tel que représenté à la figure 12.The user then installs a carabiner (5) by engaging it in the hole (23) of the lever (16), as illustrated in FIG. 11. Then, it fixes its harness (3) to the carabiner, for example, through the loops mooring (4), as shown in Figure 12.
Dans la position illustrée à la figure 12, l'antichute (1) est bloqué contre toute descente intempestive vers le bas (BA) empêchant la chute de l'utilisateur mais pourra être déplacé vers le haut (HA) par rotation vers le haut selon (R1) du levier (16), comme cela est illustré à la figure 13. En montant, l'utilisateur fait pivoter le levier (16) vers le haut (HA) selon (R2) jusqu'à ce que le mousqueton soit en butée sur les butées (20a) et (20b) des flasques. Dans cette position intermédiaire, le levier interdit toute possibilité au câble de quitter la gorge (9) et dès relâchement du levier, celui-ci pivote à nouveau vers le bas selon (R1), ce qui provoque le blocage sur le câble de l'antichute. En descente, le poids de l'antichute (1) et le ressort permettent au levier (16) de rester en butée sur les butées (20a) et (20b) des flasques (12a) et (12b). Ainsi, l'utilisateur peut descendre sans intervenir sur l'antichute (1). En cas de chute ou de descente brutale, le levier (16) pivote vers le bas (BA) selon (R1), tandis que la rampe de blocage (25) vient pincer le câble (6).In the position illustrated in figure 12, the fall arrester (1) is blocked against any untimely descent to the bottom (BA) preventing the fall of the user but can be moved up (HA) by rotation upwards along (R1) of the lever (16), as illustrated in the figure 13. When climbing, the user swivels the lever (16) upwards (HA) according to (R2) until the carabiner abuts on the stops (20a) and (20b) flanges. In this intermediate position, the prohibited lever any possibility for the cable to leave the groove (9) and as soon as the lever, it pivots again according to (R1), which causes the blocking on the fall arrestor cable. Downhill, the weight of the fall arrester (1) and the spring allow the lever (16) to remain in abutment on the abutments (20a) and (20b) flanges (12a) and (12b). So the user can descend without intervening on the fall arrester (1). In the event of a fall or abrupt descent, the lever (16) pivots downwards (BA) according to (R1), while that the locking ramp (25) pinches the cable (6).
D'après la description ci-dessus, on constate que l'antichute comprend un système de butées (20a, 20b) pour le mousqueton, système de butées qui limite le pivotement du levier dans une position intermédiaire quand l'utilisateur passe ce levier de la position de fermeture vers la position d'ouverture. Il est alors impossible à l'utilisateur de dépasser cette position intermédiaire, et il est alors impossible au câble de quitter la gorge de retenue, la came (10) étant encore engagée dans la zone de retenue du câble, comme cela apparaít à la figure 13. On notera aussi que le dégagement (1 Sa, 15b) permet le déplacement du mousqueton (5) et donc du levier (16) de la position de fermeture jusqu'à la position intermédiaire selon laquelle le mousqueton est en appui sur les deux butées (20a, 20b). Dans la position intermédiaire de la figure 13, on constate qu'il y a un jeu (j) entre le câble et la came (10), ce qui permet un libre coulissement à la fois vers le haut (HA) et vers le bas (BA). Toutefois, dès qu'il y a chute, l'antichute (1) revient immédiatement dans sa position de blocage tel qu'illustré à la figure 12.From the above description, we see that the fall arrester includes a system of stops (20a, 20b) for the carabiner, system of stops which limit the pivoting of the lever in a position intermediate when the user passes this lever from the position of closing to the open position. It is then impossible for the user to exceed this intermediate position, and it is then impossible for the cable leaving the retaining groove, the cam (10) still being engaged in the cable retention area, as shown in Figure 13. We also note that the clearance (1 Sa, 15b) allows the displacement of the carabiner (5) and therefore the lever (16) from the closed position to the intermediate position according to which the carabiner rests on the two stops (20a, 20b). In the intermediate position of figure 13, there is a clearance (j) between the cable and the cam (10), which allows free sliding both upwards (HA) and downwards (BA). However, as soon as there is a fall, the fall arrester (1) immediately returns in its locked position as illustrated in figure 12.
Par ailleurs, l'antichute est avantageusement métallique comme, par exemple, en acier inoxydable. Ajoutons, comme cela apparaít plus particulièrement aux figures 6 et 8 illustrant l'antichute dans sa position d'ouverture extrême, que la longueur (L2) du levier est telle que son extrémité (22) fait saillie au-delà des rampes supérieures (18a, 18b).Furthermore, the fall arrester is advantageously metallic such as, for example, stainless steel. Add, as it appears more particularly in Figures 6 and 8 illustrating the fall arrester in its position of extreme opening, that the length (L2) of the lever is such that its end (22) projects beyond the upper ramps (18a, 18b).
La figure 14 représente une variante d'exécution selon laquelle le levier (16) ne frotte pas sur la paroi (11a) du premier flasque (12a). A cet effet, il est prévu une rondelle (210) disposée autour de l'axe (21) entre ledit levier (16) et la paroi (11a), tel que cela apparaít sur le dessin dans la zone en coupe.FIG. 14 represents an alternative embodiment according to which the lever (16) does not rub on the wall (11a) of the first flange (12a). In this Indeed, there is provided a washer (210) disposed around the axis (21) between said lever (16) and the wall (11a), as it appears in the drawing in the sectioned area.
Les figures 15 et 16 sont des vues illustrant une variante d'exécution selon laquelle la rampe de blocage (25) comprend deux saillies de blocage, à savoir, une saillie supérieure (250) et une saillie inférieure (251). Par ailleurs, selon cette variante, la rampe inférieure (17a, 17b) s'étend sur une plus grande longueur que précédemment pour s'étendre au-delà et au-dessus du plan horizontal (H). Notons aussi qu'il est prévu un organe complémentaire de sécurité constitué par un cliquet pivotant (40) sollicité à la fermeture par un ressort. Ledit cliquet (50) étant destiné à condamner le dégagement intempestif du support d'assurage (6) par le passage (40). Figures 15 and 16 are views illustrating a variant embodiment according to which the locking ramp (25) comprises two locking projections, namely, an upper projection (250) and a projection lower (251). Furthermore, according to this variant, the lower ramp (17a, 17b) extends over a greater length than previously for extend beyond and above the horizontal plane (H). Note also that an additional safety device is provided, consisting of a pawl pivoting (40) urged to close by a spring. Said pawl (50) being intended to condemn the untimely release of the support belay (6) through the passage (40).
Notons aussi que dans cette variante il est prévu des moyens de verrouillage complémentaires (51, 52, 53) pour le levier (16) de telle sorte qu'en position totalement inversée du dispositif tel qu'illustré en figure 17 il y ait verrouillage dudit levier (16) dans sa position d'ouverture extrême. A cet effet, il est prévu une pige coulissante (51) destinée à coulisser librement dans un trou (52) réalisé dans le levier, tandis qu'en position de verrouillage, l'extrémité de la pige, par son propre poids, s'engage dans un trou (53) correspondant réalisé dans l'axe (21).Note also that in this variant, means are provided for complementary locks (51, 52, 53) for the lever (16) so that in a completely inverted position of the device as illustrated in FIG. 17 there is locking of said lever (16) in its extreme open position. For this purpose, there is provided a sliding rod (51) intended to slide. freely in a hole (52) made in the lever, while in position locking, the end of the rod, by its own weight, engages in a corresponding hole (53) made in the axis (21).
Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et représentés à titre d'exemples, mais elle comprend aussi tous les équivalents techniques ainsi que leurs combinaisons.Of course, the invention is not limited to the modes of realization described and represented as examples, but it includes also all technical equivalents and their combinations.
