Embodiment Construction

[0059] in Figure 1 to 12 In the illustrated embodiment, the self-locking descender-tether device 1 according to the present invention allows the rope 3 to be controlled in the loosening direction shown by the arrow F ( Figure 5 to 7 ) To release. Therefore, the rope 3 includes an input end 3A, an output end 3B, and a middle section 3C passing through the self-locking descender-tether device 1.

[0060] Generally, the self-locking descender-tether device 1 includes a connecting device 4 and a connecting mechanism 5.

[0061] The connecting device 4 is formed to ensure the connection with the rope 3 while controlling the sliding or locking of the rope 3 in the connecting device 4.

[0062] The coupling mechanism 5 is formed to allow the descender-tether device 1 to be selectively coupled to a fixed point or a user's safety belt.

[0063] The connecting device 4 includes a connecting body 4 a having a proximal end 4 b connected to the coupling mechanism 5.

[0064] In addition, the conn...

Abstract

The self-blocking descender-belay device (1) according to the invention comprises: a first lateral guide flange (6) for the rope, comprising a braking nose (4e), a second lateral guide flange (7) for the rope, which is separated from the first flange (6) by a transverse gap (8) for passage of the rope, and can be displaced between a spaced position for putting into place and removal of a rope, and a closed position in which the rope is trapped in the transverse gap (8) for passage of the rope, a cam (4d) which is engaged between the first and second flanges (6, 7) and is mobile towards and away from the braking nose (4e), and is thrust towards the braking nose (4e) by a cam return spring, the transverse gap (8) for passage of the rope extending between a rope input in the vicinity of the braking nose (4e), and a rope output opposite, the rope output having a large opening such as to permit free orientation of the rope output end between a blocking orientation in which the rope surrounds the cam (4d), and a release orientation in which the rope passes through the transverse gap (8) for passage of the rope directly, and without thrusting the cam (4d) towards the braking nose (4e).

Description

Technical field [0001] The present invention relates to a self-locking descender-belay device, which is designed to control the release of the rope, for example, for lowering a person with the rope, or for tying a person on the rope. Background technique [0002] Various structures of descender-tether devices are already known, such as those described in document EP0688581B1. [0003] This known type of descender-tether device includes: [0004] -A first side guide flange for the rope, which includes a braking protrusion, [0005] -A second side guide flange for the rope, which is separated from the first flange by a lateral gap for the passage of the rope, and can be used in the spaced position and the distance for putting the rope in place and removing the rope The rope is constrained to move between the closed positions in the lateral gap used as the rope channel, [0006] -A cam, which is engaged between the first and second flanges and can move towards and away from the braking p...
