Abstract

The friend (automatic wedge) wedges into rock fissure by means of the spring 3 which, acting on the eccentric 1, presses the latter against the rock. A traction on the support arm 4 is sufficient to make it wedge firmly, protecting the climber in the event of a fall. In order to withdraw the friend (automatic wedge) it is sufficient to pull on the return arm 2, which decreases the width of the friend (wedge) and thus allows its recovery.

Description

COINCEUR AUTOMATIQUE
L'invention concerne les instruments du type coinceur automatique, dont le but est de coincer dans une fissure rocheuse afin de protéger un
Rrimpeur en cas de chute.AUTOMATIC COINCE
The invention relates to instruments of the automatic jammer type, the purpose of which is to wedge in a rocky crack in order to protect a
Climper in the event of a fall.

Il est composé de deux parties
1) un coinceur "excentrique" de forme particulière,
2) une tige support permettant un encrage.It is made up of two parts
1) an "eccentric" jammer of a particular shape,
2) a support rod allowing inking.

Les deux parties étant reliées par un axe décentre sur 1'ltexcen- trique", et un ressort permettant le rappel de celui-ci. The two parts being connected by an axis off-center on the "eccentric", and a spring allowing the return thereof.

Différentes tailles sont prévues puisque son rapport mini-maxi est de 1,4 (al-a2-a3).  Different sizes are planned since its minimum-maximum ratio is 1.4 (al-a2-a3).

REVENDICATIONS la présente invention concerne l'instrument du type coinceur automatique (B). the present invention relates to the automatic jammer type instrument (B). Son but est de se coincer automatiquement dans une fissure rocheuse, meme a bords parallèles. ceci de façon a constituer un encrage solide pendant l'escalade. Its purpose is to automatically get stuck in a rocky crack, even with parallel edges. this so as to constitute a solid inking during the climbing. Les dispositifs communs de ce genre sont, soit plus complexes et encombrants, soit d'un usage moins sur. Common devices of this kind are either more complex and bulky, or less safe to use. Le coinceur, selon l'invention, est facile a poser et à déposer dans les fissures à bords parallèles ou dans les trous rocheux. The jammer according to the invention is easy to install and to deposit in cracks with parallel edges or in rocky holes. Il est composé de deux pièces principales ("l'excentrique" (1) et le support (4)), relies par un axe décentré sur "ltexcentrique" (6). It is composed of two main parts ("the eccentric" (1) and the support (4)), connected by an off-center axis on "ltexcentric" (6). Le ressort permet a l'excentrique de toujours être dans sa largeur la plus grande pour faire pression sur le rocher, par écartement. The spring allows the eccentric to always be in its greatest width to put pressure on the rock, by spacing. Le bras de rappel (2) (relié à "l'excentrique" par l'intermédiaire de la corde à piano (7)) permet la pose et la dépose du coinceur par simple pression, ce qui diminue la largeur de l'excentrique (a3). The return arm (2) (connected to the "eccentric" via the piano wire (7)) allows the installation and removal of the jammer by simple pressure, which reduces the width of the eccentric ( a3). Ceci grâce à la forme très particulière de "l'excentrique", forme à largeur progressive, et dentéepour un meilleur accrochage sur les grattons du rocher.  This thanks to the very particular shape of the "eccentric", shape with progressive width, and toothed for a better attachment on the rock scrapers.
