Abstract
Description
L'invention concerne un appareil de sécurité sur corde, comportant :
- un premier flasque et un deuxième flasque mobile, délimitant un espace transversal dans lequel est agencé un galet monté sur un premier axe solidaire du premier flasque,
- et des moyens d'articulation du deuxième flasque comprenant un deuxième axe autorisant un mouvement de pivotement entre une position fermée emprisonnant la corde dans l'espace transversal, et une position ouverte pour la mise en place de la corde sur le galet.
- a first flange and a second movable flange, delimiting a transverse space in which is arranged a roller mounted on a first integral axis of the first flange,
- and articulation means of the second flange comprising a second axis allowing a pivoting movement between a closed position trapping the rope in the transverse space, and an open position for the establishment of the rope on the roller.
Une poulie bloqueur PRO TRAXION commercialisée par la demanderesse, sert en escalade ou les travaux en hauteur pour le hissage d'une charge lourde. Elle comporte une poulie montée à rotation libre sur un premier axe d'un flasque fixe, et un flasque mobile articulé autour d'un deuxième axe tubulaire décalé du premier axe. Un mousqueton d'amarrage traverse en position fermée le deuxième axe creux, et un orifice aligné du premier flasque. Le deuxième flasque est ainsi ouvrable sans se déconnecter de l'amarrage. On peut ainsi installer la corde une fois la poulie amarrée. Un téton ou cliquet de blocage est apte à verrouiller le deuxième flasque en position fermée, mais rien n'empêche de déverrouiller le téton et d'ouvrir le deuxième flasque lorsque la poulie est sous charge.A PRO TRAXION blocking pulley marketed by the plaintiff, serves climbing or work at height for hoisting a heavy load. It comprises a pulley mounted for free rotation on a first axis of a fixed flange, and a movable flange hinged about a second tubular axis offset from the first axis. A mooring carabiner crosses in the closed position the second hollow shaft, and an aligned orifice of the first flange. The second flange is thus openable without disconnecting from the mooring. It is thus possible to install the rope once the pulley moored. A pin or locking pawl is able to lock the second flange in the closed position, but nothing prevents Unlock the pin and open the second flange when the pulley is under load.

L'objet de l'invention consiste à réaliser un appareil de sécurité sur corde, ayant un flasque ouvrable dont on veut sécuriser l'ouverture accidentelle sous charge.The object of the invention is to provide a rope safety device having a working flange which is to ensure accidental opening under load.
L'appareil anti-chute selon l'invention est caractérisé en ce que :
- le premier flasque présente du jeu par positionnement du deuxième axe dans un orifice du premier flasque, le diamètre extérieur du deuxième axe étant inférieur à celui de l'orifice pour définir ledit jeu,
- d'une encoche de retenue coopérant avec le premier axe pour le verrouillage de l'appareil dans la position fermée lorsque le galet est sous charge,
- et d'un verrou actionné par un organe de commande pour assurer son déblocage en autorisant l'ouverture du deuxième flasque lorsque l'appareil n'est plus sous charge.
- the first flange has play by positioning the second axis in an orifice of the first flange, the outer diameter of the second axis being less than that of the orifice to define said clearance,
- a retaining notch cooperating with the first axis for locking the apparatus in the closed position when the roller is under load,
- and a lock actuated by a control member to ensure its release by allowing the opening of the second flange when the device is no longer under load.
Tout actionnement involontaire de l'organe de commande du verrou rend impossible l'ouverture du deuxième flasque, lequel reste verrouillé en position fermée lorsque l'appareil est sous charge.Unintentional actuation of the lock control member makes it impossible to open the second flange, which remains locked in the closed position when the device is under load.
Selon un mode de réalisation préférentiel, l'encoche de retenue est en forme de crochet dans lequel s'engage l'extrémité du premier axe suite au déplacement du deuxième flasque vers la position fermée. Une rampe est agencée à l'entrée de l'encoche pour provoquer avec le verrou un double verrouillage du deuxième flasque en position fermée, et dans l'état de charge sur le galet.According to a preferred embodiment, the retaining notch is hook-shaped in which the end of the first axis engages following the displacement of the second flange towards the closed position. A ramp is arranged at the entrance of the notch to cause with the lock a double locking of the second flange in the closed position, and in the state of load on the roller.
Lorsque l'appareil n'est pas sous charge, le deuxième flasque mobile peut être déverrouillé en faisant pivoter l'organe de commande dans le sens de déverrouillage du verrou. Le déplacement du deuxième flasque dans le sens d'ouverture provoque en début de course, une réaction de la rampe sur le premier axe, entraînant un léger mouvement de translation du premier flasque vers le haut jusqu'au rattrapage du jeu. L'encoche est alors libérée et échappe au premier axe en permettant l'ouverture totale du deuxième flasque.When the device is not under load, the second mobile flange can be unlocked by rotating the control member in the unlocking direction of the lock. The displacement of the second flange in the opening direction causes at the beginning of the stroke, a reaction of the ramp on the first axis, resulting in a slight translational movement of the first flange upwards until catching the game. The notch is then released and escapes the first axis by allowing the total opening of the second flange.
Le galet peut être fixe, ou monté à rotation libre sur le premier axe. Le galet peut aussi être constitué en roue libre à rotation unidirectionnelle et à blocage dans le sens inverse.The roller can be fixed, or mounted to free rotation on the first axis. The roller may also be constituted by unidirectionally rotating free wheel and blocking in the opposite direction.
L'invention s'applique à tout type d'appareils de sécurité sur corde et à flasque ouvrable devant être verrouillé sous charge, notamment un descendeur, une poulie avec ou sans bloqueur intégré.The invention applies to any type of safety devices on rope and openable flange to be locked under load, including a descender, a pulley with or without built-in blocker.

En référence aux figures, un appareil de sécurité sur corde, désigné par le repère général 10, comporte un premier flasque 11, et un deuxième flasque 12 mobile destiné à occuper une position fermée et une position ouverte. Le premier flasque 11 est semi-fixe, et est doté d'un premier axe 13 sur lequel est monté un galet 14 muni d'une gorge 15 annulaire pour le guidage de la corde C. Le galet 14 est monté à rotation libre sur le premier axe 13 avec interposition d'un coussinet 16 autolubrifiant ou d'un roulement à billes, l'ensemble constituant une poulie ouvrable. La charge s'applique sur le galet 14 par l'intermédiaire de la corde C lorsque le deuxième flasque 12 est en position fermée.Referring to the figures, a rope safety device, designated by the
Le galet 14 peut aussi être fixe ou être constitué par une roue libre à rotation unidirectionnelle et à blocage dans le sens inverse. L'invention s'applique à tout type d'appareils de sécurité sur corde et à flasque ouvrable, notamment un descendeur, une poulie, etc...The
A la partie supérieure du deuxième flasque 12 mobile est fixé un deuxième axe 17, lequel est creux pour le passage d'un mousqueton M d'attache destiné à être accroché à un amarrage. Le deuxième axe 17 creux est logé avec un jeu J dans un orifice 18 du premier flasque 11, et peut pivoter lors de l'entraînement du deuxième flasque 12 vers la position ouverte. Le diamètre du deuxième axe 17 creux est inférieur à celui de l'orifice 18 pour définir ledit jeu J en translation du premier flasque 11 dans le sens de la hauteur. L'écartement transversal entre les deux flasques 11, 12 correspondant sensiblement à la longueur du deuxième axe 17. La présence du jeu J rend le premier flasque 11 semi-fixe.At the upper part of the second
Selon une variante, le deuxième axe 17 peut être plein.According to one variant, the
La face interne du deuxième flasque 12 mobile est munie d'une encoche 19 de retenue en forme de crochet, dans laquelle peut s'engager l'extrémité du premier axe 13 lorsque le deuxième flasque 12 se déplace vers la position fermée. Cette encoche 19 est pourvue d'une rampe 20 provoquant le verrouillage dans la position fermée lorsque le galet 14 ou poulie est sous charge. Un verrou 21 pivotant sur un axe 22 est sollicité par un ressort de rappel (non représenté) vers une position de blocage pour verrouiller positivement le deuxième flasque 12 dans la position fermée.The inner face of the second
La face avant du deuxième flasque 12 est équipée d'un organe de commande 23 accouplé au verrou 21 pour assurer son déblocage permettant l'ouverture du deuxième flasque 12 pivotant lorsque l'appareil n'est plus sous charge.The front face of the
Chaque flasque 11, 12 comporte un trou 24, 25 dans la partie inférieure, lesdits trous étant alignés dans la position fermée et autorisant l'accrochage d'un mousqueton additionnel pour cadenasser l'appareil dans la position fermée.Each
Le fonctionnement de l'appareil de sécurité 10 à poulie ouvrable selon l'invention est le suivant :
