Abstract

Le descendeur-assureur autobloquant (1) selon l'invention comprend :
- un premier flasque latéral de guidage de corde (6), comportant un nez de freinage (4e),
- un second flasque latéral de guidage de corde (7), séparé du premier flasque (6) par un intervalle transversal de passage de corde (8), et déplaçable entre une position écartée pour la mise en place et l'enlèvement d'une corde et une position fermée dans laquelle la corde est emprisonnée dans l'intervalle transversal de passage de corde (8),
- une came (4d), engagée entre les premier et second flasques (6, 7), mobile vers et à l'écart du nez de freinage (4e), et sollicitée vers le nez de freinage (4e) par un ressort de rappel de came,
- l'intervalle transversal de passage de corde (8) se développant entre une entrée de corde au voisinage du nez de freinage (4e) et une sortie de corde opposée,
- la sortie de corde étant à grande ouverture de façon à autoriser une libre orientation du brin de sortie de corde entre une orientation de blocage où la corde entoure la came (4d) et une orientation de libération où la corde parcourt l'intervalle transversal de passage de corde (8) en direct et sans solliciter la came (4d) vers le nez de freinage (4e).

The self-locking chute-insurer (1) according to the invention comprises:
a first lateral guiding flange (6), comprising a braking nose (4th),
a second lateral chord-guiding flange (7), separated from the first flange (6) by a transverse rope-passing gap (8), and movable between a spaced-apart position for the insertion and removal of a chord (7); rope and a closed position in which the rope is trapped in the transverse rope passing interval (8),
- a cam (4d), engaged between the first and second flanges (6, 7), movable towards and away from the braking nose (4e), and biased towards the braking nose (4e) by a return spring cam,
the transverse rope passing interval (8) developing between a rope entrance in the vicinity of the braking nose (4e) and an opposite rope exit,
the rope exit being at a large aperture so as to allow a free orientation of the rope exit strand between a locking orientation where the rope surrounds the cam (4d) and a release orientation where the rope traverses the transverse interval of rope passage (8) directly and without biasing the cam (4d) towards the braking nose (4th).
