Abstract
Description
La présente invention est relative à un dispositif permettant de mettre un bateau à l'eau ou de l'en sortir. The present invention relates to a device for putting a boat in or out of the water.
Deux procédés sont actuellement employés pour effectuer ces manoeuvres. Two methods are currently used to perform these maneuvers.
Le premier consiste à utiliser une rampe pénétrant dans l'eau sur laquelle on déplace un chariot portant le bateau, ledit chariot, qui constitue la remorque du bateau,étant généralement freiné par le véhicule tracteur lors de la descente. The first consists in using a ramp entering the water on which a carriage carrying the boat is moved, said carriage, which constitutes the trailer of the boat, being generally braked by the towing vehicle during the descent.
L'emploi de ce procédé est donc limité à des bateaux de faible tonnage car si la pente de la rampe est importante, la force du véhicule tracteur est insuffisante pour freiner ou tirer la remorque. La solution consistant à diminuer la pente de la rampe n'est pas avantageuse. En effet, plus la pente est faible, plus la rampe doit être longue. De ce fait, sa réalisation nécessiterait une place trop importante dont on ne peut pas disposer,notamment dans un port de plaisance.The use of this process is therefore limited to small tonnage boats because if the slope of the ramp is significant, the force of the towing vehicle is insufficient to brake or tow the trailer. The solution of reducing the slope of the ramp is not advantageous. The lower the slope, the longer the ramp must be. Therefore, its realization would require too much space which we can not have, especially in a marina.
Le second procédé consiste à utiliser une grue. C'est le procédé le plus employé surtout lorsque le bateau est quillé mais l'implantation d'une grue n'est pas toujours possible ni môme autorisée dans les ports de plaisance en raison de son caractère inesthétique. The second method is to use a crane. It is the most widely used process, especially when the boat is keeled, but the installation of a crane is not always possible or even authorized in marinas because of its unsightly nature.
La présente invention qui remédie à ces inconvénients est remarguable en ce que la mise à l'eau est réalisée par l'entremise d'une plate-forme mobile normalement située au-desSsus de l'eau et susceptible d'ôte abaissée pour immerger la remorque et la coque du bateau. The present invention which overcomes these drawbacks is remarkable in that the launching is carried out by means of a mobile platform normally located above the water and capable of being lowered to immerse the trailer and hull of the boat.
Selon un mode de réalisation, chaque côté de la plate-forme constitue le côté supérieur d'un parallélogramme déformable dont le côté inférieur est situé au fond de l'eau. According to one embodiment, each side of the platform constitutes the upper side of a deformable parallelogram whose lower side is located at the bottom of the water.
L'invention sera mieux comprise par la description qui va suivre faite en se référant aux dessins annexés à titre d'exemple indicatif seulement, sur lesquels:
La figure 1 est une vue schématique en élévation montrant le dispositif de l'invention
La figure 2 est la vue de dessus de la figure 1;
La figure 3 est une vue partielle en perspective montrant un détail de réalisation.The invention will be better understood from the description which follows made with reference to the accompanying drawings by way of indicative example only, in which:
Figure 1 is a schematic elevational view showing the device of the invention
Figure 2 is the top view of Figure 1;
Figure 3 is a partial perspective view showing a detail of embodiment.
En se reportant aux dessins, on voit que le problème à résoudre consiste à mettre à l'eau, à partir d'un quai 1, un bateau B reposant sur sa remorque R usuelle. Referring to the drawings, it can be seen that the problem to be solved consists in launching, from a quay 1, a boat B resting on its usual trailer R.
Selon l'invention, la remorque R est placée manuellement ou à l'aide d'un véhicule tracteur, sur une plateforme 2 formant le prolongement du quai 1 et s'étendant audessus de l'eau. According to the invention, the trailer R is placed manually or by means of a towing vehicle, on a platform 2 forming the extension of the platform 1 and extending above the water.
Des moyens sont prévus sur la plate-forme 1 pour verrouiller la remorque. Un exemple de ces moyens est illustré sur la figure 3 et il se compose essentiellement d'un tendeur 3 articulé par une de ses extrémités sur la plateforme et présentant à l'autre un crochet 4 susceptible de venir en prise avec l'un des longerons L de la remorque R. Means are provided on the platform 1 for locking the trailer. An example of these means is illustrated in FIG. 3 and it essentially consists of a tensioner 3 articulated by one of its ends on the platform and presenting to the other a hook 4 capable of coming into engagement with one of the side members. L of trailer R.
Chaque côté de la plate-forme 2 constitue le côté supérieur d'un parallélogramme déformable dont le côté inférieur est situé au fond de l'eau F. Each side of the platform 2 constitutes the upper side of a deformable parallelogram whose lower side is located at the bottom of the water F.
Selon un mode de réalisation, la plate-forme 2 est reliée au fond F par deux paires 5 et 6 de bras identiques articulés sous elle en 7 par leur extrémité supérieure et en 8, sur des embases 9 en béton placées au fond de l'eau par leur extrémité inférieure. According to one embodiment, the platform 2 is connected to the bottom F by two pairs 5 and 6 of identical arms articulated under it at 7 by their upper end and at 8, on concrete bases 9 placed at the bottom of the water through their lower end.
On comprend qu'après avoir placé la remorque portant le bateau sur la plate-forme, le pivotement des bras 5-6 selon la flèche F1 provoque l'abaissement, parallèlement à elle-même, de la plate-forme et son immersion. Cet abaissement est poursuivi jusqu'au moment où la poussée de l'eau soulève le bateau qui se dégage des berceaux de la remorque et peut alors être manoeuvré et éloigné du dispositif pour permettre la remontée de la plate-forme et le retrait de la remorque. We understand that after placing the trailer carrying the boat on the platform, the pivoting of the arms 5-6 according to arrow F1 causes the lowering, parallel to itself, of the platform and its immersion. This lowering is continued until the push of the water lifts the boat which emerges from the cradles of the trailer and can then be maneuvered and moved away from the device to allow the ascent of the platform and the removal of the trailer .
La manoeuvre de la plate-forme est assurée par des câbles 10 s'enroulant sur des tambours Il dont la rotation est commandée par un dispositif à vis sans fin 12 actionné par un moto-réducteur 13 disposé sur le quai 1. The platform is maneuvered by cables 10 winding on drums II, the rotation of which is controlled by a worm device 12 actuated by a geared motor 13 arranged on the platform 1.
Il faut noter qu'en position haute de la plate-forme les bras 5-6 sont légèrement inclinés à l'opposé du quai 1. It should be noted that in the high position of the platform the arms 5-6 are slightly inclined opposite the platform 1.
De cette façon, le relâchement des câbles 10 détermine le pivotement des bras dans le sens F1, le moto-réducteur freinant alors la descente par l'entremise du dispositif à vis sans fin.In this way, the loosening of the cables 10 determines the pivoting of the arms in the direction F1, the gear motor then braking the descent by means of the worm device.
Naturellement, des moyens sont prévus pour verrouiller la plate-forme en position haute, tels que le crochet 14 de la figure 1 dont le pivotement en vue du déverrouillage peut être commandé manuellement ou non. Naturally, means are provided for locking the platform in the high position, such as the hook 14 of FIG. 1, the pivoting of which for unlocking can be controlled manually or not.
Le dispositif qui vient d'être décrit ci-dessus ne présente aucune superstructure disgracieuse, occupe sur le plan d'eau une surface à peine supérieure à celle d'un bateau et nécessite un minimum de travaux pour son implantation. The device which has just been described above has no unsightly superstructure, occupies an area on the water surface barely greater than that of a boat and requires a minimum of work for its installation.
