Abstract
La présente invention a pour objet d'assurer automatiquement la sécurité du grimpeur sans l'assistance d'un second de cordée et sans intervention du grimpeur lui-même. La présente invention permet simultanément un glissement limité de la corde tout en la bloquant automatiquement sans intervention du grimpeur ou d'un tiers. Par un soulagement de la tension de la corde post-chute, elle retrouve sa mobilité pour reprendre l'escalade ou continuer la descente. Ce freinage dynamique protège le grimpeur et les points d'ancrage dans la paroi à escalader. Ce système d'assurage n'encombre pas le grimpeur puisqu'il reste accroché au pied de la voie à escalader.The present invention aims to automatically ensure the safety of the climber without the assistance of a second roped and without intervention of the climber himself. The present invention simultaneously allows a limited slip of the rope while blocking automatically without intervention of the climber or a third party. By relieving the tension of the post-fall rope, she finds her mobility to resume climbing or continue the descent. This dynamic braking protects the climber and the anchor points in the wall to be climbed. This belay system does not clutter the climber since it remains attached to the foot of the path to climb.
Description
Description Présentation de l'invention La présente invention a pour objet d'assurer automatiquement la sécurité du grimpeur sans l'assistance d'un second de cordée et sans intervention du grimpeur lui-même. Il existe de nombreux systèmes d'assurage classés en deux catégories : les systèmes autobloquants qui bloquent automatiquement la chute, les systèmes freins qui provoquent un freinage par action volontaire du second de cordée. Ces deux catégories ont les inconvénients de nécessiter la présence d'un assureur et un choc important sur le grimpeur et sur les points d'assurance. Ou un freinage insuffisant, donc dangereux pour, le grimpeur et un risque de brûlure des mains de l'assureur. La présente invention permet simultanément un glissement limité de la corde tout en la bloquant automatiquement sans intervention du grimpeur ou d'un tiers. Par un 20 soulagement de la tension de la corde post-chute, elle retrouve sa mobilité pour reprendre l'escalade ou continuer la descente. Ce freinage dynamique protège le grimpeur et les points d'ancrage dans la paroi à escalader. Ce système d'assurage n'encombre pas le grimpeur puisqu'il reste accroché au pied de la voie à escalader. 25 La maquette prototype est en AU4G et comporte une chambre conique dans laquelle peut coulisser un frein en silicone de même conicité perforé pour laisser passer la corde et comportant une échancrure permettant le resserrement de ce frein autour de cette corde au moment de la chute, par entraînement dynamique. Le glissement 30 de ce frein peut être amélioré par un adhésif sur sa surface en contact avec le corps du système. Un ressort à boudins permet le retour au coulissement de la corde pour repartir. La chambre du ressort doit être calibrée car trop courte, elle empêchera le frein de fonctionner et trop longue, elle empêchera le ressort de jouer son rôle de débloquer la corde. Tous les systèmes de glissement avec resserrement, quels que soient leurs formes sont couverts par le présent brevet. Pour ne pas le fatiguer, le ressort devra être du double de la longueur de la course maxi du frein dans son logement. Et sa raideur sera évaluée approximativement par la droite obtenue par la course du frein en fonction de la force nécessaire à son retour initial.Description The present invention aims to automatically ensure the safety of the climber without the assistance of a second roped and without intervention of the climber himself. There are many belay systems classified in two categories: self-locking systems that automatically block the fall, braking systems that cause braking by voluntary action of the second roped. These two categories have the disadvantages of requiring the presence of an insurer and a significant impact on the climber and the insurance points. Or insufficient braking, so dangerous for the climber and a risk of burning the hands of the insurer. The present invention simultaneously allows a limited slip of the rope while blocking automatically without intervention of the climber or a third party. By relieving the tension of the post-fall rope, she finds her mobility to resume climbing or continue the descent. This dynamic braking protects the climber and the anchor points in the wall to be climbed. This belay system does not clutter the climber since it remains attached to the foot of the path to climb. The prototype model is made of AU4G and comprises a conical chamber in which a silicone brake of the same perforated conicity can be slid to allow the rope to pass and comprising a notch allowing the tightening of this brake around this rope at the moment of the fall, by dynamic training. The sliding of this brake can be improved by an adhesive on its surface in contact with the body of the system. A coil spring allows the sliding back of the rope to start again. The spring chamber must be calibrated because too short, it will prevent the brake from working and too long, it will prevent the spring from playing its role of unlocking the rope. All slip systems with tightening, whatever their shape, are covered by this patent. To avoid fatigue, the spring should be twice the length of the maximum stroke of the brake in its housing. And its stiffness will be evaluated approximately by the line obtained by the stroke of the brake according to the force necessary for its initial return.
La variabilité de la course du frein est tributaire de la masse du corps en chute. Pour calibrer la chambre du ressort, mieux vaut la prévoir un peu longue et y installer des rondelles de compensation, d'épaisseur variable, de 2/10ème, 1 mm et 2 mm. Complétée éventuellement par des rondelles-ressorts qui donneront un élan initial pour débloquer la corde. La maquette, enregistrée sur clé USB, a donné d'excellents résultats répétitifs sans défaut de freinage durant une quinzaine de chutes. Après quoi, par prudence, il serait nécessaire de changer le frein, quoique encore utilisable. Ce frein ne devrait coûter que quelques euros alors que la corde, à plus d'une cinquantaine d'euros, aura été changée une à plusieurs fois entre-temps. Avant de fixer l'instrument au pied de la voie, s'assurer par une traction brutale et relâchement, du bon fonctionnement du système.The variability of the brake stroke is dependent on the mass of the falling body. To calibrate the spring chamber, it is better to provide it a little long and install compensation washers, of variable thickness, 2 / 10th, 1 mm and 2 mm. Possibly supplemented by spring washers that will give an initial boost to unlock the rope. The model, recorded on a USB key, gave excellent results repetitive without braking fault during a fortnight of falls. After which, as a precaution, it would be necessary to change the brake, although still usable. This brake should cost only a few euros while the rope, more than fifty euros, has been changed one to several times in the meantime. Before attaching the instrument to the foot of the track, make sure that the system is working properly by means of a sudden pull and release.
Un système expérimental est en cours de réalisation et pourra être utilisé avec chutes de 80 kg et plus.An experimental system is in progress and can be used with falls of 80 kg and more.
