Abstract

Device for guiding the sheet and providing automatic pulling on capstans. The invention relates to a device making it possible to prevent overlapping of the sheet on the dolly of capstans, to pull and eject the outlet length and to block from a distance. It consists of a cylindroconical dolly 1 which is flared out towards the bottom, surrounded by a fixed helical guide 2 the last turn of which supports a compensated presser 5 having at its upper part a groove 6 pressing the sheet 3 under the head of the dolly 8 which is coated by an adherent material 7. A spring 10 and a remote control 11 make it possible to manoeuvre the presser in rotation in order to block as required. A sheet ejector 9 directs the outlet length. The device according to the invention is particularly intended for capstans for sailing boats.

Description

La présente invention concerne un dispositif permettant d'améliorer le fonctionnement des winchs cabestans par un guidage de l'écoute, un tirage autonome et une éjection dirigée du brin de sortie. The present invention relates to a device making it possible to improve the operation of the capstan winches by guiding the sheet, an autonomous draw and a directed ejection of the output strand.

t'enroulement de l1écoute sur les winchs cabestans est traditionnellement éffectué en spires jointives sur le corps de la poupée, puis elle passe autour d'un renvoi fixe avant de s'engager entre les joues d' une poulie a flasques crantées faisant office de taquet coinceur. the winding of the sheet on the capstan winches is traditionally carried out in contiguous turns on the body of the doll, then it passes around a fixed return before engaging between the cheeks of a pulley with notched flanges acting as a cleat jammer.

Ce dispositif demande, de la part de l'utilisateur, une grande attention lors, des manoeuvres pour ne pas mettre l > écoute en état de chevauchement, d'autre part il est nécéssaire pour choquer, même très peu, de la dégager completement du taquet coinceur tournant. This device requires, on the part of the user, great attention during maneuvers so as not to put the listening in an overlapping state, on the other hand it is necessary to shock, even very little, to release it completely from the rotating cleat.

Le dispositif selon l'invention, permet de remédier ces inconvénients, il comporte en effet une poupée cylindro-cônique évasée vers le bas, elle est entourée par un guide hélicoidal fixe dont la dernière spire supporte un presseur compensé présentant a sa partie supérieure une gorge glissante appliquant l'écoute sous la tête de la poupée. Le presseur est muni d'un ressort l'obligeant par rotation sur le guide a venir appliquer l'écoute contre le dessous de la tête de la poupée,il comporte également un éjecteur qui écarte celle-ci du dispositif et sert en même temps de levier de manoeuvre. The device according to the invention overcomes these drawbacks, it indeed comprises a cylindrical-conical headstock flared downwards, it is surrounded by a fixed helical guide whose last turn supports a compensated presser having at its upper part a groove slippery applying the sheet under the head of the doll. The presser is provided with a spring forcing it by rotation on the guide to apply the sheet against the underside of the head of the headstock, it also includes an ejector which separates it from the device and serves at the same time to operating lever.

La figure I represente en élévation, le dispositif selon l'invention. Figure I shows in elevation, the device according to the invention.

La figure 2 représente, en coupe, le détail du coincement de 1' écoute entre le presseur compensé et le dessous de la tête de la poupée. FIG. 2 represents, in section, the detail of the jamming of the sheet between the compensated presser and the underside of the head of the headstock.

La figure 3 montre, en perspective, le presseur compensé seul. Figure 3 shows, in perspective, the compensated presser alone.

Le dispositif représenté sur la figure I comporte une poupée cylindro-cônique (1) évasée vers le bas, dont la génératrice, selon l'axe vertical, offre une courbe sensiblement voisine de celle dite chaînette, permettant a l'écoute serrée autour par la force de traction de monter d'elle-même par glissement axial jusqu'en haut de la poupée. The device shown in FIG. 1 comprises a cylindrical-conical headstock (1) flared downwards, the generator of which, along the vertical axis, offers a curve substantially close to that known as the chain, allowing listening to be tightened around by the tensile force to go up by axial sliding to the top of the headstock.

Elle est entourée par un guide hélicoïdal (2) fixe, solidaire du pont, disposant d'un pas à gauche Si elle tourne dans le sens horaire ou à droite dans un sens inverse. La dernière spire du guide (2) supporte un presseur compensé (5) engagé par vissage et présentant h sa partie supérieure, dans un plan perpendiculaire à l'axe de l'ensemble, une gorge circulaire (6) de guidage et de pression, glissante ou roulante, appliquant l'écoute dans l'angle, revêtu d'un matérian ad hèrent (7) formé par le haut de la partie cylindrique de la poupée et l'epaulement de la tête (8). Le presseur compense est muni d'un ressort (10) ayant tendance à le faire tourner dans le sens dévissant
Pour réduire le jeu entre lui-même et le dessous de la tête de la poupée jusqu'au coincement de l'écoute pour son entraînement. Un éjecteur d' écoute (9) situé au bout de la gorge du presseur compensé (5) écarte celle-ci du dispositif et sert er. eme temps de levier de manoeuvre.It is surrounded by a fixed helical guide (2), integral with the bridge, having a step to the left If it turns clockwise or to the right in an opposite direction. The last turn of the guide (2) supports a compensated presser (5) engaged by screwing and having at its upper part, in a plane perpendicular to the axis of the assembly, a circular groove (6) for guiding and pressure, sliding or rolling, applying the sheet in the corner, coated with an adherent material (7) formed by the top of the cylindrical part of the headstock and the shoulder of the head (8). The compensating presser is provided with a spring (10) which tends to rotate it in the unscrewing direction
To reduce the play between itself and the underside of the head of the doll until the sheet jamming for its training. A sheet ejector (9) located at the end of the throat of the compensated presser (5) moves it away from the device and serves. same operating lever time.

Une commande à distance (il) pas à l'intérieur du guide (2) pour choquer à la demande. A remote control (it) not inside the guide (2) to shock on demand.

Le dispositif selon l'invention, est particulièrement destiné aux winchs cabestans pour bateaux à voiles. The device according to the invention is particularly intended for capstan winches for sailing boats.

Claims

1) Device for guiding listening, ensuring autonomous drawing, ejection of the output strand and making it possible to shock from a distance on the capstan winches, characterized in that it comprises a cylindrical tapered headstock flared downwards (1) surrounded by a fixed helical guide (2) supporting a compensated presser (5) applying the sheet (3) under the head of the headstock (8) coated with an adherent material (7).
