Abstract

The invention relates to a device intended for manually lifting a mooring line which allows the user to rest between each pull on the mooring. It consists of a U-shaped support clevis 1 intended to be fixed to the deck of the boat, a compound chain wheel 2 is held on the clevis 1 by a pin 6. A ratchet 3 is fixed onto the clevis 1 by means of a pin 4. This ratchet prevents the chain wheel 2 from rotating in the boat mooring direction and thus blocks the mooring, which allows the user to rest without the part of the mooring which has just been raised on board returning to the water.

Description

La présente-invention concerne un dispositif mécanique conçu pour aider au levage manuel d'un mouillage sur un bateau de faible tonnage. The present invention relates to a mechanical device designed to assist in the manual lifting of an anchorage on a small tonnage boat.

Le levage manuel d'un mouillage (ensemble comprenant généralement du cordage suivi d'une longueur de chaîne au bot de laquelle est fixée une ancre ou un grappin) sur un petit bateau, se fait traditionnellement à la force des bras, par l'intermédiaire d'une poulie d'étrave libre sur son axe qui renvoie le mouillage dans l'axe de tire de l'utilisateur qui doit produire un effort constant jusqu ta ce que le mouillage soit totalement remonté à bord. The manual lifting of an anchorage (an assembly generally comprising rope followed by a length of chain to the bot to which an anchor or grapple is attached) on a small boat, is traditionally done by force of arms, via of a free bow pulley on its axis which returns the anchor in the axis of pull of the user who must produce a constant effort until the anchor is completely brought back on board.

Le dispositif, selon l'invention, permet de remédier à cet inconvénient. I1 comporte, en effet, une poulie mixte permettant de recevoir une chaîne, (barbotin) ou un cordage
(poulie crantée). Cette poulie mixte, peut tourner librement dans le sens mouillage bateau, mais est retenue par un cliquet dans l'autre sens. Le cliquet s'opposant au poids du mouillage, celui-ci se coince dans la gorge crantée s'il s'agit de cordage, ou dans la partie barbotin, s'il s'agit de chaîne, ce qui permet à l'utilisateur de se reposer entre chaque traction.
The device according to the invention overcomes this drawback. I1 comprises, in fact, a mixed pulley allowing to receive a chain, (gypsy) or a rope
(toothed pulley). This mixed pulley can rotate freely in the boat mooring direction, but is retained by a ratchet in the other direction. The pawl opposing the weight of the mooring, it gets stuck in the notched groove if it is rope, or in the gypsy part, if it is chain, which allows the user to rest between each pull.

La figure I représente de face, le dispositif selon l'invention
La figure 2 représente en coupe le dispositif selon l'invention
Le dispositif représenté su-r les figures I et 2, comporte un barbotin mixte (2) dont les formes permettent de recevoir une chaîne et dont le fond comporte une gorge en V crantée (7) permettant de recevoir et de maintenir des cordages de diamètres différents. Sur l'une des faces extérieures, sont disposées des dents de loup (8) en nombre égal aux encoches (12) placées de telle façon, que le cliquet (3) bloque le barbotin (2) dans une position permettant de retenir la chaîne quand on cesse la traction, sans que celle-ci ne saute. La chaîne n'étant retenue que par un maillon, il faut que celui-ci soit-orienté dans le sens de la traction de l'utilisateur.
Figure I shows from the front, the device according to the invention
Figure 2 shows in section the device according to the invention
The device shown in FIGS. I and 2 comprises a mixed gypsy (2) the shapes of which make it possible to receive a chain and the bottom of which comprises a notched V-groove (7) making it possible to receive and hold ropes of diameters different. On one of the outer faces, wolf teeth (8) are arranged in a number equal to the notches (12) placed in such a way that the pawl (3) blocks the gypsy (2) in a position allowing the chain to be retained when you stop pulling, without it jumping. The chain being retained only by a link, it must be oriented in the direction of traction of the user.

Le barbotin (2) est maintenu par un axe (6) dans une chappe-support (I) en U destinée à être fixée sur le pont du bateau par 11 intermédiaire de trous (9) de faço à ce que la channe puisse monter verticalement jusqu'au barbotin (2), sans obstacle pouvant géner la manoeuvre. Le cliquet (3) est articulé sur un axe (4) de façon à pouvoir être rabattu vers l'avant afin de libérer le barbotin (2) lors du filage du mouillage ; une butée (5) retient le cliquet (3) pour le maintenir à portée de main. Il a une forme allongée (10), permettant sa préhension sans risquer de se prendre la main entre le mouillage et le barbotin (2). Cette forme sert aussi de contre-poids pour faciliter l'engrènement de la dent (II) du cliquet (3) dans celle du barbotin. The gypsy (2) is held by a pin (6) in a support-chappe (I) in U intended to be fixed on the deck of the boat by 11 through holes (9) so that the chain can go up vertically up to the gypsy (2), without obstacle which could hinder the maneuver. The pawl (3) is articulated on an axis (4) so that it can be folded forward to release the gypsy (2) when spinning the anchor; a stop (5) retains the pawl (3) to keep it close at hand. It has an elongated shape (10), allowing it to be grasped without risking taking your hand between the anchorage and the gypsy (2). This shape also serves as a counterweight to facilitate the engagement of the tooth (II) of the pawl (3) in that of the gypsy.

La figure 3 représente, de profil, un barbotin (2) sur lequel les dents de loup (8), sont remplacées par des encoches (13), taillées sur la circonférence de l'une de ses faces,
La figure 4 représente en perspective, une dispositif selon l'invention (A) installé à la place de l'un ou l'autre des réas (15), d'un davier à basculeur (14), monté sur une pièce d'étrave (16).
FIG. 3 represents, in profile, a sprocket (2) on which the wolf teeth (8) are replaced by notches (13), cut on the circumference of one of its faces,
Figure 4 shows in perspective, a device according to the invention (A) installed in place of one or the other of the sheaves (15), of a tilting forceps (14), mounted on a piece of bow (16).

La figure 5 représente, en perspective, un dispositif selon l'invention (A) placé à l'envers sur le pont, et en arrière de l'étrave de façon à ce que le mouillage passe par un davier classique (19) puis sous le dispositif (A). La traction sur le mouillage s'effectuant verticalement. FIG. 5 represents, in perspective, a device according to the invention (A) placed upside down on the deck, and behind the bow so that the wetting passes through a conventional davit (19) then under the device (A). The traction on the mooring takes place vertically.

Ce montage est à utiliser sur les bateaux dont les formes d'avant ne permettent pas le montage de la présente invention sur l'étrave même du bateau.This mounting is to be used on boats whose forward shapes do not allow the mounting of the present invention on the bow of the boat.

La figure 6 représente, en perspective, un dispositif selon l'invention (A), adapté à une pièce d'étrave (16) quelconque. Plusieurs dispositifs peuvent être montés cote à cote sur une chappe-support multiple ou une pièce d'étrave multiple. Le dispositif est fabrioué en matériaux inoxydables.  FIG. 6 represents, in perspective, a device according to the invention (A), adapted to any bow piece (16). Several devices can be mounted side by side on a multiple support chappe or a multiple bow piece. The device is made of stainless materials.
