Abstract

The snap hook, esp for a person working at heights above 3m with a harness and safety line, consists of a stainless steel body with pivoted catches (2) on its two tips. Each catch is able to pivot sideways, is equipped with a piston and is spring-loaded, so that it returns to its original position once released. The snap hook is suitable for use with a 12 mm dia cable, and allows any intermediate anchoring elements on the cable to pass through the hook without having to open it.

Description

MOUSQUETON DE SECURITE SPECIAL POUR LIGNES DE VIE
La présente invention concerne un mousqueton spécial pour lignes de vie assurant la sécurité d'une personne travaillant prés d'un vide d'une hauteur minimun de 3 métres.SPECIAL SAFETY SNAP HOOK FOR LIFE LINES
The present invention relates to a special carabiner for lifelines ensuring the safety of a person working near a vacuum with a minimum height of 3 meters.

Le dispositif selon l'invention peut être appliqué dans tous les cas, où pour des raisons d'intervention quelconques un ouvrier auraît à se déplacer en hauteur. The device according to the invention can be applied in all cases, where for reasons of any intervention a worker would have to move in height.

L'équipement complet est donc pourvu : D'un cable de diamètre 12 rmn fixé à une hauteur moyenne accéssible par l'utilisateur, au moyen de pattes scellées à chaque bout, et de pattes intermediaires distantes l'une de l'autre de 5 métres. The complete equipment is therefore provided with: A cable with a diameter of 12 nm fixed at an average height accessible by the user, by means of lugs sealed at each end, and intermediate lugs distant from each other by 5 meters.

L'équipement individuel de sécurité de l'utilisateur, sera composé du mousqueton , d'une longe réglable et d'un harnais. The user's personal safety equipment will consist of the carabiner, an adjustable lanyard and a harness.

D'une manière générale on sait qu'un mousqueton classique peut être utilisé sur une ligne de vie de faible longueur, mais ne pourra en aucun cas être placé sur celle-ci si elle possède des points intermédiaires de fixation. In general, we know that a classic carabiner can be used on a short lifeline, but can in no case be placed on it if it has intermediate fixing points.

L'invention à donc plus particulièrement pour but de pouvoir supprimer cet inconvenient. Elle propose donc un mousqueton susceptible de pouvoir passer : points d'ancrage, virages, descentes et montées, sur des lignes de vie de longueur indifférente tout en garantissant la sécurité individuelle de la personne. The invention therefore more particularly aims to be able to eliminate this drawback. It therefore offers a carabiner likely to be able to pass: anchor points, turns, descents and climbs, on lifelines of any length while guaranteeing the individual safety of the person.

D'une façon plus précise, ce mousqueton comprend, un corps d'une forme similaire aux mousquetons ordinaires tout en étant plus résistant selon les normes en vigueur, mais en offrant la particularité de s'ouvrir dans les deux sens perpendiculaires à la vue face ou figure n0 1 ; au moyen de deux linguets (2) pourvu chacun d'un axe (5) assurant le pivotement, d'un ressort de rappel (3) et d'un guide (4) permettant le retour des linguets dans leur position initiale. More precisely, this carabiner includes a body of a shape similar to ordinary carabiners while being more resistant according to the standards in force, but offering the particularity of opening in both directions perpendicular to the front view. or Figure 1; by means of two latches (2) each provided with an axis (5) ensuring the pivoting, a return spring (3) and a guide (4) allowing the latches to return to their initial position.

Un mode de réalisation de l'invention sera décrit ci-après à titre d'exemple non limitatif, avec références aux dessins annexés
- La figure 1 ou vue de face.An embodiment of the invention will be described below by way of non-limiting example, with reference to the accompanying drawings
- Figure 1 or front view.

- La figure 2 ou coupe AA située dans l'axe du mécanisme illustrant sa composition. - Figure 2 or section AA located in the axis of the mechanism illustrating its composition.

- La figure 3 ou vue de gauche, illustrant le principe et les possibilités de manoeuvre des linguets. - Figure 3 or left view, illustrating the principle and the possibilities of operation of the latches.

Tel que représenté sur la figure 1, ce mousqueton est réalisé entiérement en acier inoxydable. As shown in Figure 1, this carabiner is made entirely of stainless steel.

De deux linguets (2) dans lesquels sont insérés les pièces (3) et (4) permettant leur retour en position initiale ; pivotant autour d'un axe (5).  Two latches (2) into which are inserted the parts (3) and (4) allowing their return to the initial position; pivoting about an axis (5).

Claims (3)

REVENDICATIONS 1) Mousqueton de sécurité pour lignes de vie caractérisé en ce qu'il comprend deux linguets équipés chacun d'un piston et d'un ressort provoquant le retour en position de départ de celui-ci. 1) Safety carabiner for lifelines characterized in that it comprises two catches each equipped with a piston and a spring causing the latter to return to the starting position. 2) Mousqueton de sécurité selon la revendication 1 Caractérisé par le fait que l'ouverture se fait non parallèlement au plan du mousqueton , mais perpendiculairement à celui-ci ; de façon à laisser le passage à une patte intermédiaire adaptée au profil de la pièce,servant à fixer le cable contre un support. 2) safety carabiner according to claim 1 characterized in that the opening is not parallel to the plane of the carabiner, but perpendicular thereto; so as to allow passage to an intermediate tab adapted to the profile of the part, serving to fix the cable against a support. 3) Mousqueton selon l 'une des revendications precédentes caractérisé par le fait qu'il ne pourra être employé qu'avec un cable de diamètre 12 =, g ainsi que des pattes intermédaires spécialement adaptées à ce mousqueton.  3) Carabiner according to one of the preceding claims, characterized in that it can only be used with a cable with a diameter of 12 =, g as well as intermediate legs specially adapted for this carabiner.
