According to the document FR 2 922 200, a fall protection device for climber secured by a rope comprises a frame, a casing pivotally mounted on the frame, a pulley pivotally mounted in the casing with the same axis of pivoting as the casing, the pulley being rotated by the rope and having locking means adapted to block the rotation of the pulley relative to the housing when the speed of rotation of the pulley exceeds a predetermined speed, the housing carrying a movable stop capable, in cooperation with a stop fixed chassis, to ensure a pinch of the rope to llein the movement of the rope.
Un inconvénient des dispositifs de ce type est qu'il est nécessaire de tendre le brin mou de la corde, c'est-à-dire le brin non lié au grimpeur.  A disadvantage of devices of this type is that it is necessary to tension the soft strand of the rope, that is to say the strand not bound to the climber.
En effet, lorsque le brin mou est lâché, le grimpeur n'est plus sécurisé en cas de chute. Indeed, when the soft strand is dropped, the climber is no longer secure in case of a fall.
Un but de l'invention est d'éviter l'inconvénient précité et d'augmenter la sécurité du grimpeur pendant la montée et pendant la descente.  An object of the invention is to avoid the aforementioned drawback and increase the safety of the climber during ascent and during descent.
L'invention a pour objet un dispositif de sécurité, pour grimpeur sécurisé par une corde, comportant un châssis, un boîtier monté pivotant sur le châssis, une poulie montée pivotante dans le boîtier avec même axe de pivotement que le boîtier, la poulie étant entraînée en rotation par la corde et comportant des moyens de verrouillage aptes à bloquer la rotation de la poulie par rapport au boîtier lorsque la vitesse de rotation de la poulie dépasse une vitesse,.. prédéterminée, le boîtier portant une butée mobile susceptible, en coopération avec une butée fixe du châssis, d'assurer un pincement de la corde pour bloquer le mouvement de la corde en cas de chute du grimpeur. Il comporte en outre, une pièce ovoïde montée pivotante sur le châssis autour d'un axe excentré, ladite corde glissant autour de ladite pièce ovoïde en faisant au moins une spire et étant pincée entre ladite pièce ovoïde et une troisième butée pour freiner le mouvement de la corde en cas de chute du grimpeur. The invention relates to a safety device, for climber secured by a rope, comprising a frame, a casing pivotally mounted on the frame, a pulley pivotally mounted in the housing with the same pivot axis as the casing, the pulley being driven in rotation by the rope and comprising locking means adapted to block the rotation of the pulley relative to the housing when the speed of rotation of the pulley exceeds a predetermined speed .., the housing carrying a movable stop capable, in cooperation with a fixed stop of the chassis, to ensure a pinching of the rope to block the movement of the rope in case of fall of the climber. It further comprises an ovoid piece pivotally mounted on the frame about an eccentric axis, said rope sliding around said ovoid piece making it at least one turn and being clamped between said ovoid piece and a third stop to slow the movement of the rope in case of climber's fall.
Avantageusement, ladite pièce ovoïde bascule entre une première position en contact avec une première butée lorsque la corde est remontée par traction sur le brin mou, et une deuxième position en contact avec une deuxième butée en cas de chute du grimpeur. Advantageously, said ovoid piece tilts between a first position in contact with a first stop when the rope is raised by traction on the soft strand, and a second position in contact with a second stop in case of fall of the climber.
De préférence, lesdites première et troisième butées sont fixes. Preferably, said first and third stops are fixed.
Avantageusement, ladite deuxième butée est réglable pour contrôler le pincement plus ou moins fort de la corde entre la pièce ovoïde et la troisième butée. Advantageously, said second stop is adjustable to control the more or less strong nip of the rope between the oval piece and the third stop.
Selon un mode de réalisation de l'invention, ladite deuxième butée a un profil de came, le réglage de la deuxième position de la pièce ovoïde étant assuré par rotation de la deuxième butée. According to one embodiment of the invention, said second stop has a cam profile, the adjustment of the second position of the ovoid piece being ensured by rotation of the second stop.
Selon un mode de réalisation de l'invention, ladite deuxième butée est réglable en position par translation. According to one embodiment of the invention, said second stop is adjustable in position by translation.
Avantageusement, le boîtier présente à sa périphérie des lumières oblongues arquées, coopérant avec des entretoises portées par le châssis, pour assurer le pivotement du boîtier. Advantageously, the housing has at its periphery arcuate oblong slots, cooperating with spacers carried by the frame, to ensure the pivoting of the housing.
L'invention sera mieux comprise, et d'autres buts, détails, caractéristiques et avantages de celle-ci apparaîtront plus clairement au cours de la description qui va suivre d'un mode de réalisation de l'invention donné à titre d'exemple purement illustratif et non limitatif, en référence aux dessins annexés dans lesquels : The invention will be better understood, and other objects, details, features and advantages thereof will appear more clearly in the following description of an embodiment of the invention given by way of example purely illustrative and nonlimiting, with reference to the accompanying drawings in which:
- la figure 1 est une vue schématique simplifiée d'un dispositif de sécurité pour grimpeur sécurisé par une corde, selon un premier mode de réalisation de l'invention, - la figure 2 est une vue analogue à la figure 1 , d'un dispositif de sécurité pour grimpeur sécurisé par une corde, selon un deuxième mode de réalisation de l'invention. FIG. 1 is a simplified schematic view of a safety device for climber secured by a rope, according to a first embodiment of the invention, - Figure 2 is a view similar to Figure 1, a safety device for climber secured by a rope, according to a second embodiment of the invention.
Le dispositif de sécurité représenté à titre d'exemple comprend, dans un premier mode de réalisation (figure 1), un châssis constitué par deux flasques 1 parallèles entre eux, maintenus à distance fixe l'un de l'autre au moyen d' entretoises telles que 2, 3. Entre les deux flasques 1 sont disposés d'une part, un boîtier 4, d'autre part une pièce ovoïde 5.  The exemplary safety device comprises, in a first embodiment (FIG. 1), a frame consisting of two flanges 1 parallel to each other, held at a fixed distance from one another by means of spacers. such as 2, 3. Between the two flanges 1 are arranged on the one hand, a housing 4, on the other hand an ovoid part 5.
Le boîtier 4 est monté pivotant autour d'un axe 6 perpendiculaire aux flasques 1. Sur sa périphérie, le boîtier 4 présente des lumières oblongues arquées 7, dont la courbure est centrée sur l'axe 6: Dans les lumières 7 sont disposées des entretoises 8 de guidage en rotation du boîtier 4.  The housing 4 is pivotally mounted about an axis 6 perpendicular to the flanges 1. On its periphery, the housing 4 has arcuate oblong slots 7, whose curvature is centered on the axis 6: In the slots 7 are arranged spacers 8 for rotating the housing 4.
A l'intérieur du boîtier 4, est disposée une poulie 9, pivotant librement sur l'axe 6. De manière connue en soi, la poulie 9 porte sur l'une de ses faces latérales un ensemble de moyens de verrouillage constitués par deux cliquets 10, 11, montés pivotants autour d'axes 12, 13, respectivement. Les extrémités opposées des deux cliquets 10, 11 sont réunies par des ressorts de rappel 14, 15. Les extrémités actives 16, 17 des cliquets 10, 11 sont destinées à coopérer avec des crans d'accrochage tels que 18 portés par la surface intérieure du boîtier 4. Ainsi, les moyens de verrouillage sont aptes à bloquer la rotation de la poulie 9 par rapport au boîtier 4 lorsque la vitesse de rotation de la poulie dépasse une vitesse prédéterminée.  Inside the casing 4, there is a pulley 9 pivoting freely on the axis 6. In a manner known per se, the pulley 9 carries on one of its lateral faces a set of locking means constituted by two pawls 10, 11, pivotally mounted about axes 12, 13, respectively. The opposite ends of the two pawls 10, 11 are joined by return springs 14, 15. The active ends 16, 17 of the pawls 10, 11 are intended to cooperate with hooking notches such as 18 carried by the inner surface of the ratchet 4. Thus, the locking means are able to block the rotation of the pulley 9 relative to the housing 4 when the speed of rotation of the pulley exceeds a predetermined speed.
Le boîtier 4 porte sur sa surface extérieure une butée mobile 19. Entre la butée mobile 19 et l'un des flasques 1 est fixé un ressort 20 de rappel en position du boîtier. En face de la butée mobile 19, fixée entre les flasques 1, est disposée une butée fixe 21. Une corde 22 passe dans la gorge de la poulie 9, et entre la butée mobile 19 et la butée fixe 21.  The housing 4 carries on its outer surface a movable stop 19. Between the movable stop 19 and one of the flanges 1 is fixed a return spring 20 in position of the housing. Opposite the movable stop 19, fixed between the flanges 1, is disposed a fixed stop 21. A rope 22 passes in the groove of the pulley 9, and between the movable stop 19 and the fixed stop 21.
Entre les deux flasques 1, en dessous du boîtier 4, est disposée la pièce ovoïde 5, qui présente une gorge destinée à recevoir la corde 22. Cette gorge est en hélice car la corde 22 fait au moins une spire complète autour de la pièce ovoïde 5. La pièce ovoïde 5 est montée pivotante autour d'un axe 23 excentré. L'axe 23 est placé en dessous du centre de gravité de la pièce ovoïde 5 qui peut ainsi basculer entre deux positions : une première position en contact avec une première butée 24, et une deuxième position en contact avec une deuxième butée 25. Between the two flanges 1, below the housing 4, is disposed the ovoid part 5, which has a groove for receiving the rope 22. This groove is in propeller because the rope 22 makes at least one complete turn around the ovoid part 5. The ovoid part 5 is pivotally mounted about an eccentric axis 23. The axis 23 is placed below the center of gravity of the ovoid part 5 which can thus switch between two positions: a first position in contact with a first stop 24, and a second position in contact with a second stop 25.
La deuxième butée 25 est réglable en position par translation par rapport à une molette de fixation 30. A cet effet, la butée 25 présente une lumière oblongue 31 qui permet son déplacement. Une troisième butée 27, est montée sur un axe 26 fixé entre les deux flasques 1. La corde 22 est pincée entre la troisième butée 27 et la pièce ovoïde 5. La position de la deuxième butée 25 assure le réglage du pincement de la corde.  The second stop 25 is adjustable in position by translation relative to a fastening wheel 30. For this purpose, the stop 25 has an oblong slot 31 which allows its displacement. A third stop 27 is mounted on an axis 26 fixed between the two flanges 1. The rope 22 is clamped between the third stop 27 and the ovoid piece 5. The position of the second stop 25 ensures the adjustment of the nip of the rope.
La corde 22, qui passe entre la butée fixe 21 et la butée mobile 19, passe ensuite dans la gorge de la poulie 9 dans le sens horaire, puis elle passe dans la gorge de la pièce ovoïde 5, toujours dans le sens horaire, et son extrémité 28 est reliée au grimpeur, c'est-à-dire à la charge éventuelle. L'autre côté de la corde par rapport au dispositif de sécurité, constitue le brin mou 29.  The rope 22, which passes between the fixed stop 21 and the movable stop 19, then passes into the groove of the pulley 9 in the clockwise direction, then it passes into the groove of the ovoid piece 5, always in the clockwise direction, and its end 28 is connected to the climber, that is to say to the possible load. The other side of the rope with respect to the safety device constitutes the soft strand 29.
En fonctionnement normal, lorsque l'on exerce une traction sur la corde 22 du côté du brin mou 29, la pièce ovoïde 5 bascule jusqu'à s'appuyer sur la première butée 24, et la corde peut librement glisser dans la gorge de la pièce ovoïde 5 et entraîner en rotation la poulie 9. Lorsque l'on exerce une traction sur la corde 22 du côté du brin 28, la pièce ovoïde 5 bascule jusqu'à s'appuyer sur la deuxième butée 25, assurant un pincement de la corde 22 entre la pièce ovoïde 5 et la troisième butée 27, ce qui freine la corde 22. Au cours de cette traction sur le brin 28 de la corde 22, la corde 22 entraîne en rotation la poulie 9. Si la traction sur le brin 28 devient forte, par exemple lors d'une chute du grimpeur, alors la poulie 9 est entraînée rapidement en rotation. Au-dessus d'une vitesse prédéterminée, les cliquets 10, 11 qui constituent des moyens de verrouillage de la poulie 9 sur le boîtier 4, s'écartent sous l'effet de la force centrifuge et viennent se bloquer sur les crans 18 de la surface intérieure du boîtier 4. La poulie 9 est alors bloquée dans le boîtier et la traction sur la corde 22 entraîne le boîtier 4 en rotation autour de l'axe 6, en étirant le ressort 20. In normal operation, when one exerts a pull on the rope 22 on the side of the soft strand 29, the ovoid piece 5 tilts until it bears on the first stop 24, and the rope can freely slide in the groove of the ovoid piece 5 and rotate the pulley 9. When one exerts a pull on the rope 22 on the side of the strand 28, the ovoid piece 5 tilts until it bears on the second stop 25, ensuring a pinch of the rope 22 between the ovoid piece 5 and the third stop 27, which brakes the rope 22. During this traction on the strand 28 of the rope 22, the rope 22 rotates the pulley 9. If the traction on the strand 28 becomes strong, for example during a fall of the climber, then the pulley 9 is driven rapidly in rotation. Above a predetermined speed, the pawls 10, 11 which constitute locking means of the pulley 9 on the housing 4, deviate under the effect of the centrifugal force and come to lock on the notches 18 of the inner surface of the 4. The pulley 9 is then locked in the housing and the traction on the rope 22 drives the housing 4 in rotation about the axis 6, by stretching the spring 20.
Au cours de sa rotation, le boîtier 4 est guidé par les lumières oblongues 7 sur les entretoises 8, et la butée mobile 19 se rapproche de la butée fixe 21 en pinçant la corde 22, ce qui a pour effet de bloquer la corde 22 et d'arrêter la chute. During its rotation, the housing 4 is guided by the oblong slots 7 on the spacers 8, and the movable stop 19 approaches the fixed stop 21 by pinching the rope 22, which has the effect of locking the rope 22 and to stop the fall.
Lorsque la chute est arrêtée, après que le grimpeur a repris pied, une légère traction sur le brin mou 29 entraîne la rotation en sens inverse de la poulie 9 et son déblocage par rapport au boîtier 4, le basculement de la pièce ovoïde 5 vers la première butée 24, et la libération de la corde au niveau de la troisième butée 27. De son côté, le ressort 20 ramène le boîtier 4 à sa position initiale et écarte la butée mobile 19 de la butée fixe 21. When the fall is stopped, after the climber has regained foot, a slight traction on the soft strand 29 causes the rotation in the opposite direction of the pulley 9 and its release relative to the housing 4, the tilting of the ovoid piece 5 towards the first stop 24, and the release of the rope at the third stop 27. On its side, the spring 20 returns the housing 4 to its initial position and moves the movable stop 19 of the fixed stop 21.
Dans l'exemple de réalisation de la figure 2, les mêmes références désignant les mêmes éléments, le boîtier 4 est de structure différente. En effet, il est monté pivotant sur l'axe 6. A l'intérieur du boîtier 4, la poulie 9 et les moyens de verrouillage au boîtier sont identiques à ceux décrits en relation avec la figure 1 et le fonctionnement du dispositif de sécurité est le même. In the embodiment of Figure 2, the same references designating the same elements, the housing 4 is of different structure. Indeed, it is pivotally mounted on the axis 6. Inside the housing 4, the pulley 9 and the locking means to the housing are identical to those described in connection with Figure 1 and the operation of the safety device is the same.
La deuxième butée 25 présente avantageusement un profil de came et elle est montée réglable en position angulaire sur un axe 26 fixé entre les deux flasques 1. Sur cet axe 26 est montée une troisième butée 27, par exemple cylindrique, en vue d'assurer un pincement de la corde 22 entre la pièce ovoïde 5 et la troisième butée 27. Ce pincement est réglé par l'intermédiaire du profil de la deuxième butée 25. En effet, la rotation de la deuxième butée 25 autour de l'axe 26 assure le réglage de la deuxième position de la pièce ovoïde 5, notamment par rapport à la troisième butée 27. The second stop 25 advantageously has a cam profile and is mounted adjustable in angular position on an axis 26 fixed between the two flanges 1. On this axis 26 is mounted a third stop 27, for example cylindrical, to ensure a pinching of the rope 22 between the ovoid part 5 and the third abutment 27. This nip is adjusted via the profile of the second abutment 25. In fact, the rotation of the second abutment 25 about the axis 26 ensures the adjusting the second position of the ovoid piece 5, in particular with respect to the third stop 27.
La pièce 5 a été décrite comme ovoïde, mais elle peut être circulaire. Cependant, elle doit être montée pivotante autour d'un axe 23 excentré. Elle présente avantageusement une gorge hélicoïdale dans laquelle peut glisser la corde 22. La gorge de la poulie 9, au contraire, est conçue pour empêcher la corde 22 de glisser, de façon à assurer la sécurité, en cas de chute, par blocage du brin 29 de la corde entre les butées 19 et 21. Exhibit 5 has been described as ovoid, but may be circular. However, it must be pivotally mounted about an eccentric axis 23. It advantageously has a helical groove in which the rope 22 can slide. The groove of the pulley 9, on the contrary, is designed to prevent the rope 22 from sliding, so as to ensure safety, in case of fall, by blocking the strand 29 of the rope between the stops 19 and 21.
