Abstract

The grip has a vertical channel (9) through which the support cable passes slidably along a vertical axis (YY'). A cam (10) formed by a ramp surface of a pivotable lever (16) selectively engages the cable as it passes through the channel, moving between open and closed positions in response to manual actuation of the lever. The free end of the lever includes a hole (23) through which a carabineer or other clip may be passed and secured. When located in the hole, the projecting ends of the clip engage stop surfaces (20a,b) on the casing of the grip, preventing pivoting movement of the lever from a closed position of the cam to its open position.

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 device of the individual pivoting lever against falls in height. It relates to a mobile fall arrester for belay support more particularly adapted to vertical belay supports, especially flexible, 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 are called upon to intervene on installations at height and which must for this purpose climb or descend along pylons or poles must be insured so as not to accidentally fall. It is, for example, the case of installers or repairers installations such as, for example, cable cars or chairlifts. It is therefore necessary to insure them so they can go up or down in full freedom, 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 On connait aussi un dispositif antichute commercialisé sous la marque CABLOC AC 350, selon le préambule de la revendication 1, qui comprend un dispositif de commande de type parallélogramme déformable auquel est fixé un mousqueton. 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 constituted by a rope or belay cable arranged vertically, also called "lifeline", to which the user connects so that it can move up or down. To this end, it is equipped with individual protection linking it to the "lifeline" and including a harness attached to a mobile fall arrester. We know by document FR A 2 144 623 a fall arrester having a retaining groove in which slides a cable, which can be locked with an integral cam a pivoting lever between an open position and closing. Furthermore, document FR-A. 2,668,937 discloses a fall arrest device with a mechanism making accidental cable release impossible We also know a fall arrest device marketed under the CABLOC brand AC 350, according to the preamble of claim 1, which includes a control device deformable parallelogram type to which a carabiner is attached. However, the known devices are not entirely satisfactory in terms of their convenience 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 particularly safe, reliable and convenient to put on in action.

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 belay support such as a cable or rope, is type comprising an axle retaining groove, in which the said belay support is retained thanks to a cam, integral with a pivoting lever between a position opening that allows the passage of the belay support in the throat and a closed position, 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 that a stop system for the carabiner limits the pivoting of the lever in an intermediate position when moving from the closing position to the position opening 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 made by the wall of a main flange, while that the fall arrester includes a secondary flange consisting of 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, a longitudinal and parallel passage is provided at the axis of the groove, said passage being limited laterally on the one hand, the first border of the flange main and, secondly, the first border of the second flange.

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 lever to move with its carabiner and delimiting the stops defining the position intermediate 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 supérieurau 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 as example, the second side border of each flanges includes a succession of two ramps, a lower ramp set back from a upper ramp to form the clearance. The ramp lower is circular with radius centered on the axis, while that the upper ramp is circular with a centered radius on the axis, knowing that the radius of said upper ramp is greater than the radius of said lower ramp, the clearance formed by the lower recessed ramp, is limited upwards by the stops arranged radially and substantially in the horizontal plane passing by 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 complementary characteristics of the invention, the lever cam is constituted by a locking ramp extended by an unlocking ramp, while the width of the lever is such that it does protrudes beyond the upper ramps when the lever is in the extreme open position.

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 will emerge from the description which follows in look at the attached drawings which are only given title of nonlimiting examples

La figure 13 représente comment est utilisé l'antichute selon l'invention.Figure 13 shows how is used the fall arrester according to the invention.

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 representing a variant with a cut partial along the pivot axis of the 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 a variant of execution, FIGS. 15 and 16 being similar views in 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 an equipment personal protection against falls from a height bearing the general reference (2) and comprising in plus said fall arrester (1) a harness (3) carrying at least a mooring loop (4) with a snap hook (5), said fall arrester (2) being intended to be connected removably on a belay support (6) vertical fixed, for example, on an intervention pylon (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, i.e. connected with the harness (3), the mobile fall arrester (1) can be at will moved up (HA) or down (BA) by sliding normal (i.e. ascent rate or user descent) along the vertical cable (6) constituting the belay support which can, by elsewhere, be constituted by a rope. In the event of a fall, which corresponds to an accelerated descent speed, the mobile fall arrester hangs on the cable. We will understand that the user (8) can then climb or descend along the pylon (7) while sliding the fall arrester up (HA) or down (BA) along the cable safety (6), if necessary, while it will be insured not to drop down by blocking its fall arrester (1) on said cable (6) constituting the support belay.

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 (11 a) 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 straight hollow profile (9) intended to receive the cable belay (6) retained there after engagement, thanks to a pivotally movable cam (10). So the profile hollow (9) is constituted by the wall (11 a) of a flange main (12a) of which the first lateral border (13a) is folded parallel to said wall, so as to form a semicircular gutter or groove (9), while that the second side border (14a) is in the wall plane and is curved to understand its part lower clearance (15a). Note that the throat has a semicircular profile with a vertical axis (YY ') and has substantially the dimension of the cable intended to be housed there. Furthermore, the locking cam (10) is integral an operating and latching lever (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 ramp lower (17a) set back from 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 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 release (15a) whose function will be explained later in the description, formed by the lower recessed ramp, is limited upwards 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) pourformer 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 plus the main flange (12a) described above and forming the groove (9), a secondary flange (12b). This the latter is integral with the main flange to be parallel thereto and spaced by a distance (d) to constitute, on the one hand, a space (e) between the two flanges intended movement of the lever (16) and, on the other hand, a longitudinal passage (40) for cable engagement (40). The secondary flange has an identical configuration to the wall (11a) of the main flange (12a). So, he consists of a wall (11b) and comprises a first lateral border (13b) straight, while the second side border (14b) is in the plane of the wall and is curved to understand at its bottom a clearance (15b). So the second border lateral (14b) comprises a succession of two ramps, a lower ramp (17b) set back relative to an upper ramp (18b) to form the clearance (15b). 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. Through elsewhere, the clearance (15b) whose function will be explained further in the description, formed by the ramp lower recessed, is limited upward by a stop (20b) arranged radially and substantially in the horizontal plane (H) passing through the pivot axis (XX ') lever (16). Add that the passage (40) is limited laterally by the first edge (13a) of the flange main (12a) and the first border (13b) of the flange secondary (12b). Of course, the width of the passage is greater than the diameter of the cable (6) intended to be there engaged, 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 pivoting 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). So he went up rotating around an axis (21) extending between the two flanges so that its hooking end (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 includes a hooking hole (23) intended to receive the hooking carabiner (5) which can be engaged thanks to the clearance (15a, 15b) provided on the edges of the flanges (12a, 12b). The hole attachment (23) is cylindrical and its axis (QQ ') is at a distance (L1) from the axis (XX ') between the value 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 hanging hole (23) a cam (10) formed by a locking ramp (25) to ensure the fall arrester lock (1) on the extended belay cable by a ramp for unlocking (26) the fall arrester allowing the sliding of said fall arrester on said cable belay (6). The lever (16) being able to take rotation around the axis (XX ') two extreme positions, an open position as illustrated in FIGS. 6 and 8, and a closed position as shown in the 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 used towards its closed position by a torsion spring (27). The latter is useful, on the one hand, for maintaining in place fall arrester (1) on the belay cable (6) when the installation and removal of the carabiner (5) and, on the other hand, to ensure a blockage of the fall arrester in the event of a fall, even before 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 displacement of the lever down by a lower stop (28) and towards the top by an upper stop (29). The lower stop (28) is produced by a small transverse wall (30) extending between the two flanges (12a, 12b) in the lower ramps area (17a, 17b), while the upper stop (29) is produced by a 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 steps of setting up the fall arrest device of the invention. The user by fitting the first flange (12a) of the fall arrester (1) in the palm of the right hand rotate with its thumb the lever (16) upwards along R1 to release the passage (40) for the cable. He brings the fall arrester (1) on the cable (6) to pass said cable (6) to the passage (40), as illustrated in FIG. 8. Then it engages the cable (6) in the groove (9) and releases the lever (16), as illustrated in figure 9. The lever (16) biased by the spring (27) pivots downward along (R2) until the locking ramp (25) pinches the cable thus retaining it in the groove (9), as this is 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 figure 11. Then, he fixes his harness (3) to the carabiner, for example, through the buckles 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 down (BA) preventing the user from falling but can be moved up (HA) by rotation towards the top along (R1) of the lever (16), as illustrated in figure 13. When climbing, the user turns the lever (16) upwards (HA) according to (R2) until the carabiner is in abutment on the stops (20a) and (20b) flasks. In this intermediate position, the lever prohibits any possibility of the cable leaving the groove (9) and as soon as the lever is released, it pivots again down according to (R1), which causes blocking on the fall arrest cable. Downhill, the weight of the fall arrester (1) and the spring allow the lever (16) to remain in abutment on the stops (20a) and (20b) of the flanges (12a) and (12b). Thus, the user can descend without intervening on the fall arrester (1). In the event of a fall or descent brutal, the lever (16) pivots downwards (BA) according to (R1), while 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 description above, we see that the fall arrester includes a system of stops (20a, 20b) for the carabiner, stop system which limits pivoting of the lever in an intermediate position when the user passes this lever from the closed position towards the open position. It is then impossible the user to exceed this intermediate position, and it is then impossible for the cable to leave the groove retaining, the cam (10) still being engaged in the cable retention area, as shown in the figure 13. Note also that the clearance (1 Sa, 15b) allows the carabiner (5) to move and therefore the lever (16) from the closed position to the position intermediary according to which the carabiner is in support on the two stops (20a, 20b). In the middle position in Figure 13, we see that there is a clearance (j) between the cable and the cam (10), which allows a free sliding both up (HA) and down (BA). However, as soon as there is a fall, the fall arrester (1) returns immediately 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 protection is advantageously metallic like, for example, stainless steel. Add, as it appears more particularly 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 ramps higher (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.Figure 14 shows an alternative embodiment that the lever (16) does not rub against the wall (11a) of the first flange (12a). To this end, provision is made a washer (210) disposed around the axis (21) between said lever (16) and the wall (11a), as it appears on 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 according to which the blocking ramp (25) comprises two locking projections, namely, an upper projection (250) and a lower projection (251). Furthermore, according to this variant, the lower ramp (17a, 17b) extends over a greater length than before to extend beyond and above from the horizontal plane (H). Note also that it is planned a complementary security organ constituted by a pivoting pawl (40) urged to close by a spring. Said pawl (50) being intended to condemn the release untimely belay support (6) by 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 it is planned complementary locking means (51, 52, 53) for the lever (16) so that in position totally inverted of the device as illustrated in figure 17 there is locking of said lever (16) in its position of extreme opening. A rod is provided for this purpose. sliding (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 embodiments described and represented as examples, but it also includes all equivalents techniques and their combinations.
