  • Publication number: 20250121253
    Abstract: A camming clamping device includes a head, a cam and a spring biasing the cam to an extended position. A textile wire element connects the cam to a trigger fitted movable between first and second positions. The cam defines a first hole and a second hole. The textile wire element passes through the first hole and second hole to introduce friction between the textile wire element and the cam. A terminal portion of the textile wire element passes through a third hole connecting the sides of the cam and/or is wedged in a groove arranged in one of the sides. The terminal portion of the textile wire element is arranged posteriorly to the second hole in a longitudinal direction of the textile wire element away from the trigger.

  • Publication number: 20240207685
    Abstract: A camming clamping device comprises a head provided with an anchor point. A cam is installed rotatable around at least one shaft between a retracted position and an extended position. A spring is functionally coupled to the cam to bias the at least one cam to the extended position. An annular end is mechanically coupled to the head. A wire element connects the head and the annular end. The wire element is in the form of a ring. The ring is folded into a U-shape with two legs joined by a central portion. The two legs are fixed to the anchor point. Four strands of the wire element connect the head and the annular end. An actuating system has a trigger installed slidingly and configured to selectively engage the retracted position.

  • Publication number: 20240207684
    Abstract: A camming clamping device comprising: a head sub-assembly including a head provided with a cam and a rod sub-assembly having a rod and at least one wire element. The wire element passes through the rod. The rod delineates a through hole designed to receive a connector. The wire element delineates the through hole. The wire element defines at least one loop that is attached to head to constitute a mechanical continuity between the head and the attachment point. The at least one loop is passed through by a tube. The tube and the at least one loop are passed through by an anchorage fixed to the head to constitute the mechanical continuity between the head and the attachment point.

  • Publication number: 20240207683
    Abstract: A camming clamping device comprises a head with a cam installed swivelling around a pivot shaft between retracted and extended positions. An annular end is mechanically coupled to the head. A rod of variable length connects the head with an annular end designed to receive a carabiner. A wire element made from textile material passes through the rod to connect the head and the annular end. A trigger is installed slidingly to selectively engage the retracted position of the cam. An adjustment device of the length of the rod defines at least a distance between the head and the annular end that is greater than a threshold distance to stretch the wire element and compress the rod in the first direction.

  • Publication number: 20240151260
    Abstract: A carabiner comprises a body and a gate fixed to the body to be movable between closed and open positions. A catch is fixed to the body and installed movable between a blocking position and a release position of the gate in the closed position. A first spring is connected to the gate and to the catch. The first spring biases the gate to the closed position and biases the catch to the blocking position. In the closed position, the first spring is curved with a first mean radius of curvature. In the open position, the first spring is curved with a second mean radius of curvature that is larger than the first radius of curvature.

  • Patent number: 11849833
    Abstract: A gear sling device comprises a body in the form of a hook with an opening and a gate fixed to the body. The gate is fitted movable with respect to the body between a first position closing the opening and a second position leaving the opening open. The body and gate define a ring. A loop is designed to fix the body to a belt of a harness or to a strap. The loop is partly bounded by the body. The gear sling device comprises a wire-like element fitted sliding inside a through hole passing through the body. The wire-like element extends from the through hole to a pressing area where a first end of the wire-like element pulls on the body. A clamp is configured to block the wire-like element and to define the size of the loop.

  • Patent number: 9533192
    Abstract: Ascender for ascending on a rope, comprising a U-shaped clamp equipped with two lateral wings delineating an internal space for passage of the rope, and with an arresting surface with spikes against which the rope is blocked in case of a fall. The two wings are provided with two openings arranged facing one another and each having an edge in the form of an inclined ramp performing guiding of a karabiner passing through the two openings. The clamp comprises a mobile control part biased by a spring to an active actuation position of the karabiner along the ramp for the rope to come into contact against the arresting surface with spikes, so as to obtain a first ready-to-block state when ascending on the rope, and a second blocking state of the clamp on the rope in the event of a fall.
