BELAY DESCENDER DEVICE ON A ROPE WITH GEARING-DOWN AND ANTI-PANIC BLOCKING

摘要

A belay descender device for a rope comprising a earn mounted rotating on a fixed flange to perform locking of the rope when said rope is under tension, and a lever articulated on the cam to perform progressive unlocking of the rope with a geared-down effect at the beginning of unlocking travel of the lever. The operating lever comprises transmission means collaborating with a guide ramp of the flange to interrupt the mechanical link with the cam after an intermediate position of the lever has been passed resulting in freeing from said ramp outside the gearing-down area. The end of the guide ramp of the flange corresponds to the anti-panic position of the transmission means, enabling automatic locking of the canvas soon as the gearing-down area has been passed.

1. A belay descender device for a rope comprising:
a cam mounted rotating on a fixed flange to perform locking of the rope when said rope is under tension, an operating lever or handle articulated on the cam to cause progressive unlocking of the rope with a geared-down effect at the beginning of the unlocking travel of the lever,wherein the operating lever comprises transmission means collaborating with a guide ramp of the fixed flange to interrupt the mechanical link with the cam after an intermediate position of the lever has been passed, resulting in freeing from said ramp outside the gearing-down area, and the end of the guide ramp of the flange corresponds to the anti-panic position of the transmission means enabling automatic locking of the cam as soon as the gearing-down area has been passed.
