  • Publication number: 20240093737
    Abstract: A clamping device includes a roller rotating around an axis. A member is fixed to the roller. The member is designed to contact a clamp. The member is mounted movable with respect to the axis to contact the clamp or not. Rotation of the roller generates a centrifugal force designed to move the member towards the clamp. When the speed of rotation of the roller reaches a threshold value, the member contacts the clamp to block the roller. The roller is provided with a stop mounted fixedly to the roller and has a fourth contact area. In the second member position, a third contact area of the member is pressing on the fourth contact area. The third contact area is arranged opposite the second contact area.

  • Publication number: 20240093736
    Abstract: A detection device comprises a roller rotating around an axis. A member is fixed to the roller. The member is designed to come into contact with a clamp. The member is mounted movable with respect to the axis to come into contact the clamp or not. Rotation of the roller generates a centrifugal force designed to move the member towards the clamp. When the speed of rotation of the roller reaches a threshold value, the member come into contact with the clamp to block the roller. The member has a flyweight and a ratchet separated by a plane perpendicular to the first axis of rotation of the roller. The plane is offset with respect to the contact surface between the member and the clamp. The flyweight is located farther from the axis than the contact area with the clamp in a radial direction.

  • Patent number: 10716960
    Abstract: 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, 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 cam as soon as the gearing-down area has been passed.

  • Patent number: 10487867
    Abstract: The carabiner comprises: a body defining an insertion slot of a rope extended by a securing area of the rope, a first clamp fitted movable between a standby position of the rope in the insertion slot and an obstruction position when the rope is in the securing area, the obstruction position being configured to prevent insertion of another rope in the securing area, a second clamp configured to allow movement of the rope from the insertion slot to the securing area and to prevent movement of the rope from the securing area to the insertion slot.

  • Patent number: 9498660
    Abstract: A fall arrest safety apparatus on a rope includes 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 clamp.

  • Patent number: 9227092
    Abstract: 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.

  • Patent number: 9192792
    Abstract: A fall arrest safety apparatus with blocking on a rope, comprising: a rigid body provided with a trunking for housing the rope, a securing system designed to swivel between a closed position to collaborate with the rope by blocking the latter at the bottom of the trunking in case of a fall, and an open position releasing access to the trunking for fitting or removal of the rope, and a control device to move said securing system from the closed position to the open position, and vice-versa, wherein the control device comprises a pair of gripping cleats able to be actuated simultaneously to stabilize and lock the securing system in the open position, the two gripping cleats being arranged side by side on a transverse pivot-pin integral to the pivoting securing system.

  • Patent number: 8584814
    Abstract: 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.
