Abstract

The invention concerns a fall-prevention device with automatic return (1) comprising: - a casing (2) having a front face (20) and a rear face (21) separated by the thickness (E) of said casing (2), - a drum (3) mounted in rotation about an axis of rotation (Χ-Χ'), said drum (3) being designed to receive a tether (5) intended to be wound around said drum (3), said device (1) being characterised in that it comprises an opening (13) that is provided through at least one of said front (20) and rear (21) faces, so as to be accessible from the outside of said casing (2), and that extends longitudinally coaxial to said axis of rotation (Χ-Χ') through at least a fraction of the thickness (E) of said casing (2). - Personal fall protection equipment.

Abstract

The invention concerns a fall-prevention device with automatic return (1) comprising: - a winder around which a tether (2) is intended to be wound, said winder being capable of being actuated in rotation - a means for automatically blocking the rotation of the winder in the unwinding direction in case of a fall, comprising: o an obstacle relative to which the winder can move in rotation, o a ratchet rigidly connected to the winder and designed to shift between a first position in which the ratchet does not interfere with said obstacle, such that said winder rotates freely, and a second position in which the ratchet can interfere with said obstacle to prevent the winder from rotating in the unwinding direction, characterised in that it comprises an automatic return means intended to return said ratchet alternately into one or the other of said first and second positions. Fall-prevention devices with automatic return.

Abstract

The invention concerns a fall-prevention device (1) with automatic return, comprising: - a casing (2), - a drum winder mounted rotating relative to said casing (2), - a tether (3) intended to be wound around said drum and comprising a free portion (32) that extends out of said casing (2), - an automatic return means that exerts a return force tending to rotate the winder in a winding direction (E), - an automatic blocking means designed to block the winder in case of a fall, said device (1) comprising a retaining means designed to automatically inhibit or limit the operation of said automatic return means such that, when said pulling force stops, the length of said free portion (32) is kept substantially close to, or identical to, said desired length. Fall-prevention devices with automatic return.

Abstract

This fall-prevention device comprises a body on which, mounted so as to rotate about a shaft, there is a wheel designed to press and roll on a belay support, and means for locking the body of the fall-prevention device on the belay support, the wheel comprising at least one centrifugal engagement device that can be moved between a disengaged position and an engaged position. The locking means comprise at least one locking member mounted so as to rotate on the body about the rotation shaft of the wheel, the locking member comprising a chock arranged to be inserted between the belay support and the wheel when the engagement device is in its engaged position, so as to immobilize the fall-prevention device on the belay support.
