  • Patent number: 10682538
    Abstract: The roping harness comprises: a belt provided with a first strap and with at least first and second comfort parts arranged between the first strap and the user, a pair of thigh straps, a connecting element connected to the pair of thigh straps, a first adjustment device configured to adjust the length of the first strap and to define the circumference of the belt. The first comfort pad and second comfort pad are fitted movable in translation with respect to one another. The first comfort pad is fitted movable in translation with respect to the first strap along the first strap. The belt comprises at least a first blocking stop configured to prevent movement of the first comfort pad with respect to the second comfort pad beyond a threshold value, the first adjustment device forming a second blocking stop of the first comfort pad.

  • 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.

  • Patent number: 8402616
    Abstract: A carabiner equipped with a swivelling gate formed by a rigid metal wire of smaller diameter than that of the body. The wire is provided with a protuberance at one of the ends to form a male latching element and an articulation loop at the opposite end for passage of the swivel-pin. A flexible return device for returning the gate to the closed position comprises a compression spring operating in conjunction with an intermediate transfer stirrup inside a housing of the body.

  • Patent number: 8387283
    Abstract: An ice crampon including a metal armature, the metal armature being composed of a horizontal support plate, at least one front spike in the form of a blade, and an adjustment device for adjusting the length of said front spike between a withdrawn position and an advanced position. In the intermediate part, each front spike comprises two circular apertures for passage of a fixing screw in both the withdrawn and advanced positions, and in the rear part comprises a sliding link operating in conjunction with a positioning cross-member securely attached to the armature when adjustment is performed. The sliding travel corresponds to the longitudinal distance between the two apertures, and the positioning cross-member is notched over its whole width with a succession of rectangular notches and indentations further enabling transverse positioning of the front spike.
