20110073417 | SELF-ARRESTING ROPE BELAY DEVICE - The invention relates to a self-arresting rope belay device comprising a cam arranged to clamp the rope when the rope is under tension, and a lever arranged to act on the cam to progressively release the rope by manual action on the lever. The lever acts on the cam respectively with a geared-down effect in an initial part of its release travel, and with a direct effect in a final part of its travel. This results in the relative movement of the cam with respect to the lever being smaller in the initial part of the travel than in the final part, which enables accurate adjustment of the braking effort and of the running speed of the rope in the initial part of travel of the lever. | 03-31-2011 |

20120012800 | PULLEY WITH UNLOCKABLE CLAMP - A pulley with an unlockable clamp, comprising a rotary roller, a pivoting trigger designed to release and clamp the rope against the roller, and control means to keep the trigger in the inactive position disabling action of the clamp, | 01-19-2012 |
20130313047 | SAFETY ROPE BLOCKER HAVING A ROTATABLE BODY - A safety rope blocker having a body provided with a through hole for the passage of an anchoring ring and a curved groove opening into the through hole for the passage of the safety rope through the anchoring ring, the body being able to rotate between a blocking position in which the safety rope is blocked by the anchoring ring against the body and a releasing position in which the safety rope slide in the curved groove, the groove includes a deviation element to allow, in the releasing position, the safety rope to slide in the curved groove and outside the through hole. | 11-28-2013 |
20140196985 | FALL ARREST SAFETY APPARATUS ON A ROPE WITH CLAMPING FUNCTION - A fall arrest safety apparatus on a rope comprising a rotary roller mounted on a pivoting arm with speed detection, and a control selector of a ratchet. The latter is able to occupy a released inactive position enabling the roller to rotate in both directions of rotation in a first fall arrest operating mode, and an active position with unidirectional blocking of the roller in rotation with respect to the arm in the descending direction corresponding to a second operating mode of the apparatus as a simple ascender. | 07-17-2014 |
