Said descender consists of two friction surfaces (18) and (19), and two (or more) friction points (5, 6) and (7, 8) arranged on both sides of an axis (16) for a rope (17) to pass through. Said friction surfaces and points are stretched over openable flanges (1) and (2) which enable the positioning of the tensioned rope, and which have an attachment point (9, 10, 14) as well as an extensible operating handle (11).

Description

Descendeur auto-bloquant sur filin tendu à points de friction variables.  Self-locking descender on tensioned rope with variable friction points.
Description  Description
La présente invention concerne un outil descendeur-bloqueur à levier sur cordes ou drisses en tension avec variabilité du dosage de la fonction descendeur.  The present invention relates to a descending-and-blocking tool lever on ropes or halyards in tension with variability of the dosage of the descending function.
II comprend :  It comprises:
Une joue fixe et une joue mobile articulée qui permettent une position dite ouverte pour passer le filin dans l'outil. '  A fixed cheek and an articulated movable cheek that allow a so-called open position to pass the rope in the tool. '
Deux réas fixés sur la joue fixe de manière à offrir un intervalle pour passer le filin entre les deux.  Two sheaves fixed on the fixed cheek so as to offer an interval to pass the rope between the two.
Deux percements en regard sur chaque joue et de part et d'autre de chaque réa et du passage du filin.  Two holes facing each cheek and on each side of each sheave and the passage of the rope.
Un moyen d'attache de l'opérateur proche du passage du filin et un levier extensible à l'opposé du moyen d'attache pour libérer de manière contrôlée le blocage et offrir une descente progressive  An attachment means of the operator close to the passage of the rope and an extensible lever opposite the attachment means to release in a controlled manner the locking and offer a progressive descent
Etat de la technique State of the art
De nombreux outils existent en descendeurs bloqueurs mais ils ne fonctionnent pas sur des filins tendus. Ils nécessitent en effet du mou pour passer le filin dans les systèmes et encore du mou pour contrôler le freinage en descente.  Many tools exist in descender blockers but they do not work on tensioned ropes. They require slack to pass the rope in the systems and slack to control braking downhill.
De nombreux outils bloqueurs sur corde tendue existent mais ils n'offrent la possibilité ni de freiner une descente ni de passer de la position blocage à la position descente instantanément sous tension.  Many tools on rope tensioners exist but they do not offer the possibility of braking a descent or to move from the blocking position to the down position instantly energized.
L'outil existant EP 1 329 242 Al offre ces possibilités mais sans dosage suivant le type et la texture de filin utilisé.  The existing tool EP 1 329 242 A1 offers these possibilities but without dosage depending on the type and the rope texture used.
Objet de l'invention Object of the invention
L'invention a pour but de remédier aux trois problématiques suivantes :  The invention aims to remedy the following three problems:
- offrir la fonction descendeur sur filins tendus  - offer the descender function on tensioned ropes
- offrir la fonction bloqueur sur filins tendus.  - offer the blocking function on tensioned ropes.
- offrir un dosage précis pour la fonction descendeur selon les diamètres et les textures de filins  - offer precise dosing for the descending function according to the diameters and textures of the ropes
L'outil répond à ces problématiques par la mise en coincement du filin tendu entre les deux surfaces planes et regardantes des réas. Le point d'attache de l'utilisateur est quasiment dans l'axe de passage du filin tendu ainsi défini. Le décoincement progressif sans à-coup pour passer de la fonction bloqueur à la fonction descendeur grâce à la poignée extensible à l'opposé symétrique du point d'attache, se fait en fonction des diamètres et de la rugosité des filins par le positionnement de mousquetons ou d'axes mobiles dans les percements placés en bordure des réas et du passage du filin. Il en résulte quatre configurations possibles de freinage qu'il faudra déterminer par essai à chaque filin. Dessins The tool responds to these problems by the wedging of the rope stretched between the two flat and looking surfaces of the sheaves. The point of attachment of the user is almost in the axis of passage of the stretched rope thus defined. Progressive smooth release from the blocking function to the descending function thanks to the extendable handle, which is symmetrical on the opposite side of the attachment point, depends on the diameters and the roughness of the ropes by the positioning of carabiners. or moving axes in the holes placed at the edge of the sheaves and the passage of the rope. This results in four possible braking configurations that must be determined by testing each rope. drawings
Par convention et par respect du sens d'installation sur le filin on appellera haut le côté du point d'attache et bas le côté poignée extensible (cf dessins). By convention and respecting the direction of installation on the rope, the side of the point of attachment will be called high and the extendable handle side (see drawings).
La figure 1 représente une vue de gauche en position ouvert montrant la mise en place du filin dans l'outil.  Figure 1 shows a left view in the open position showing the establishment of the rope in the tool.
La figure 2 représente une vue de l'arrière de l'outil .  Figure 2 shows a view of the back of the tool.
La figure 3 représente quatre coupes de profil en position fermée et en tension avec les quatre positions de freinage possibles.  Figure 3 shows four profile sections in the closed position and in tension with the four possible braking positions.
Description de l'invention Description of the invention
Sur ces figures, le descendeur bloqueur sur filin tendu se compose d'une première joue dite fixe 1 agrandie par une poignée de manœuvre extensible 1 1 , et d'une deuxième joue mobile 2 en miroir en position fermée de la joue 1 (sans la poignée). Elles sont percées en 9 et 10 en haut à l'opposé de la poignée 1 1 pour constituer le point d'attache de l'opérateur. Une entretoise tubulaire 14 permet le maintien des joues à la traction, sans contrainte de torsion. In these figures, the choke descender on tensioned rope consists of a first so-called fixed cheek 1 enlarged by an extensible maneuvering handle 1 1, and a second mobile cheek 2 mirrored in the closed position of the cheek 1 (without the handle). They are drilled at 9 and 10 at the top opposite the handle 1 1 to form the point of attachment of the operator. A tubular spacer 14 keeps the cheeks to traction, without torsion stress.
L'axe longitudinal 16 de l'outil se situe approximativement au milieu de l'outil et place les trous de fixation 9 et 10 et la poignée 1 1 de part et d'autre de cet axe.  The longitudinal axis 16 of the tool is approximately in the middle of the tool and places the fixing holes 9 and 10 and the handle 1 1 on either side of this axis.
La joue dite fixe 1 présente de part et d'autre de l'axe 16 et sensiblement à égale distance de la poignée de manœuvre 1 1 et des percements 9 et 10, deux surfaces de friction 1 8 et 19 « taillées » dans des réas 3 et 4. Ces réas 3 et 4 sont fixés sur cette joue 1 par un boulon borgne 12 pour la 4 et par un boulon 1 3 avec écrou à épaulement pour la 3 qui sert aussi de point de fixation et d'axe de rotation de la joue mobile 2.  The so-called fixed cheek 1 has on either side of the axis 16 and substantially equidistant from the operating handle 1 1 and the perforations 9 and 10, two friction surfaces 1 8 and 19 "cut" in sheaves 3 and 4. These sheaves 3 and 4 are fixed on this cheek 1 by a blind bolt 12 for the 4 and a bolt 1 3 with shoulder nut for the 3 which also serves as a fixing point and axis of rotation of the mobile cheek 2.
L'épaisseur des réas 3 et 4 (dessin 2) offre un passage sensiblement plus large que le filin 1 7 entre les joues 1 et 2.  The thickness of the sheaves 3 and 4 (drawing 2) provides a substantially wider passage than the line 1 7 between the cheeks 1 and 2.
Le filin 1 7 passe en ligne droite de haut en bas selon l 'axe 1 6 en effleurant les surfaces de friction 1 8 et 19, et les percements 9 et 10 et le tube 14, et la poignée 1 1 .  The line 1 7 passes in a straight line from top to bottom along the axis 1 6 by touching the friction surfaces 1 8 and 19, and the holes 9 and 10 and the tube 14, and the handle 1 1.
Enfin et ce qui constitue l'invention : Finally and what constitutes the invention:
deux percements 5 et 6 en miroir sur les joues et jouxtant le réa 3 en haut et de l 'autre côté de l'axe 16 par rapport au point d'attache (9, 10, 14), offrent un point de friction supplémentaire (axe mobile ou mousqueton 22).  two mirrored holes 5 and 6 on the cheeks and adjoining the sheave 3 at the top and on the other side of the axis 16 with respect to the point of attachment (9, 10, 14), offer an additional point of friction ( movable axis or carabiner 22).
deux percements 7 et 8 en miroir sur les joues et jouxtant le réa 4 en bas et de l'autre côté de l'axe 16 par rapport à la poignée 1 1 , offrent un deuxième point de friction supplémentaire (axe mobile ou mousqueton 21 ).  two holes 7 and 8 mirrored on the cheeks and adjacent the sheave 4 at the bottom and the other side of the axis 16 relative to the handle January 1, offer a second additional friction point (movable axis or carabiner 21) .
La poignée de manœuvre est extensible.  The handle is extensible.
Le dispositif selon l 'invention est résumé par une action de levier variable entre les surfaces et points de frictions, et le filin, ainsi que par le dosage possible grâce à la poignée extensible. L'opérateur présente l'outil ouvert (dessin 1 ) de manière à pouvoir placer le filin 17 selon l'axe 16 entre les surfaces et points de friction. Il peut alors refermer l'outil sur le filin en faisant pivoter la joue 2 jusqu'à la position miroir et en frappant un mousqueton 20 dans les percements 9 et 10. The device according to the invention is summarized by a variable lever action between the surfaces and points of friction, and the rope, as well as by the possible dosage thanks to the expandable handle. The operator presents the open tool (drawing 1) so as to place the rope 17 along the axis 16 between the surfaces and friction points. He can then close the tool on the rope by rotating the cheek 2 to the mirror position and striking a carabiner 20 in the holes 9 and 10.
L'usage habituel de l'outil serait qu'en pesant dans le mousqueton 20, l'on contraigne le filin jusqu'au blocage de l'outil, qu'on débloquerait par traction sur la poignée à l'opposé. Trois solutions supplémentaires à choisir s'offrent à l'opérateur en présentant au filin des points de friction différents par mise en place d'axes mobiles ou de mousquetons dans les percements 7-8 et/ou 5-6 : The usual use of the tool is that by weighing in the carabiner 20, it forces the rope until the locking of the tool, which would unlock by pulling on the handle opposite. Three additional solutions to choose from are available to the operator by presenting the different friction points by setting up moving axes or carabiners in the 7-8 and / or 5-6 holes:
Position 2 : un point de friction décalé en bas en 7-8. Position 2: a point of friction shifted down to 7-8.
Position 3 : deux points de friction décalés en haut 5-6 et en bas 7-8.  Position 3: two friction points offset at the top 5-6 and at the bottom 7-8.
Position 4 : un point décalé en haut 5-6. Position 4: a staggered point at the top 5-6.
Un dosage encore plus fin est permis par une poignée de manœuvre extensible. Variantes :  An even finer dosage is allowed by an expandable handle. Variations:
On peut envisager d'autres percements sur les joues pour d'autres points de friction. We can consider other holes on the cheeks for other points of friction.
Le même outil peut être développé « en double » à savoir que la joue fixe servirait de miroir pour offrir une deuxième paire de réas et une deuxième joue mobile, de manière à pouvoir utiliser l'outil sur deux filins. The same tool can be developed "in duplicate" namely that the fixed cheek would serve as a mirror to provide a second pair of sheaves and a second mobile cheek, so as to use the tool on two lines.
On peut aussi envisager le passage de deux filins plus fins dans l'outil simple. We can also consider the passage of two finer threads in the simple tool.
On peut envisager l'outil sans poignée de descente pour une fonction bloqueur seulement. One can consider the tool without handle of descent for a blocking function only.
Toutes les cotes doivent être en proportion des diamètres des filins. All dimensions must be in proportion to the diameters of the ropes.
L'outil fonctionne comme frein descendeur si la tension du filin est relâchée. The tool functions as a down-braking device if the rope tension is released.
