En référence aux figures 1 à 3, un bloqueur de pied, désigné par le repère général 10, comporte un élément bloqueur 12 associé à une paire de sangles 14, 16 pour la fixation à une chaussure. L'élément bloqueur 12 est doté d'un corps 18 métallique replié en forme de C, à l'intérieur duquel est articulée une gâchette 20 pivotante permettant la remontée le long d'une corde 11. La gâchette 20 comprend une surface de coincement 22 à picots, destinée à presser la corde contre une goulotte 24 lorsque le corps 18 de l'élément bloqueur 12 est sollicité vers le bas par le poids de l'utilisateur. Lors de la remontée le long de la corde, la gâchette 20 pivote autour de l'axe 26 dans le sens des aiguilles d'une montre vers une position d'ouverture pour libérer la corde. Une boucle de serrage 28 est associée à la première sangle horizontale 14 pour la fixation de l'ensemble au pied de l'utilisateur.With reference to Figures 1 to 3 , a foot blocker, designated by the general reference 10, comprises a blocking element 12 associated with a pair of straps 14, 16 for attachment to a shoe. The blocking element 12 is provided with a C-shaped folded metal body 18, inside which is articulated a pivoting trigger 20 allowing upward movement along a rope 11. The trigger 20 comprises a jamming surface 22 pinned, for pressing the rope against a chute 24 when the body 18 of the blocking element 12 is biased down by the weight of the user. During the ascent along the rope, the trigger 20 pivots about the axis 26 in a clockwise direction to an open position to release the rope. A clamping loop 28 is associated with the first horizontal strap 14 for fixing the assembly to the foot of the user.

Le corps 18 de l'élément bloqueur 12 est réalisé en tôle découpée, emboutie et pliée, et comporte deux dispositifs d'attache 30, 32 agencés dans la partie plane pour autoriser le passage et le réglage des sangles 14, 16. Le premier dispositif d'attache 30 supérieur est pourvu de quatre fentes 34 verticales sensiblement parallèles et alignés horizontalement en définissant deux passants 36, 38 pour le passage de la sangle 14. Le deuxième dispositif d'attache 32 inférieur comporte deux fentes 40 horizontales et parallèles formant un passant 42 pour le passage de la deuxième sangle verticale 16. Un trou 44 est ménagé dans le corps 18 pour permettre l'accrochage d'un mousqueton. Un ressort de rappel 46 est monté sur l'axe 26 pour solliciter la gâchette 20 vers la position de fermeture.The body 18 of the blocking element 12 is made of sheet metal cut, stamped and folded, and comprises two fastening devices 30, 32 arranged in the flat part to allow the passage and adjustment of the straps 14, 16.
