Abstract
Description
La présente invention a pour objet un dispositif de protection pour les parties immergées des systèmes de propulsion de bateaux. The present invention relates to a protection device for the submerged parts of boat propulsion systems.
Il est destiné à éviter la détérioration, en particulier par les coquillages, des hélices et des parties mécaniques immergées des navires équipés de moteurs hors-bord ou de moteur internes à propulseurs articulés de type"Z-DRIVE", et à l'arrt, surtout en mer, pour une période prolongée. It is intended to prevent deterioration, in particular by seashells, propellers and submerged mechanical parts of ships fitted with outboard engines or internal engines with articulated propellers of the "Z-DRIVE" type, and when stopped, especially at sea, for an extended period.
De nombreux bateaux sont immobilisés à flot durant de longues périodes lorsqu'ils ne sont pas utilisés. Many boats are tied up afloat for long periods of time when not in use.
Lorsque ces bateaux comportent des moteurs hors-bord ou des système"Z-DRIVE", il est possible, en particulier pour les hors-bord, de relever les parties immergées des systèmes de propulsion, ce qui permet à l'air salin de pénétrer dans les cylindres par la tubulure d'échappement, ce qui risque d'entraîner des dégradations des mécanismes internes. When these boats have outboard motors or "Z-DRIVE" systems, it is possible, in particular for outboards, to raise the submerged parts of the propulsion systems, which allows salty air to penetrate into the cylinders through the exhaust manifold, which may cause damage to the internal mechanisms.
C'est la raison pour laquelle, en cas d'immobilisation prolongée du navire à flot, la plupart des utilisateurs laissent les hélices en position immergées, ce qui a pour effet que certains coquillages s'accrochent sur les parties métalliques et sur le soufflet des systèmes"Z-DRIVE", en créant une croûte qu'il faut arracher avant de remettre le bateau en service, au prix d'un travail considérable de nettoyage. This is why, in the event of prolonged immobilization of the ship afloat, most users leave the propellers in the submerged position, which has the effect that certain shells catch on the metal parts and on the bellows of the "Z-DRIVE" systems, creating a crust that must be torn off before putting the boat back into service, at the cost of considerable cleaning work.
En outre ces dépôts provoquent des dégâts sur les parties externes pouvant nécessiter parfois le remplacement de certainespièces. In addition, these deposits cause damage to the external parts which may sometimes require the replacement of certain parts.
Le dispositif selon la présente invention a pour objectif de remédier à cet état de choses. Il permet en effet, pour un coût extrmement raisonnable, de protéger les parties immergées contre les dépôts d'impuretés ou l'accrochage des coquillages, et mme de maintenir ces parties au sec tout en laissant le système de propulsion immergé. The device according to the present invention aims to remedy this state of affairs. It makes it possible, for an extremely reasonable cost, to protect the submerged parts against deposits of impurities or the attachment of shells, and even to keep these parts dry while leaving the propulsion system submerged.
Il est constitué d'une enveloppe étanche en forme de sac s'enfilant sur les parties mécaniques immergées d'un propulseur articulé de type"Z-DRIVE"ou d'un moteur hors-bord de manière à les isoler du milieu aquatique, cette enveloppe comportant un bord d'ouverture permettant de la fixer de façon étanche sur une partie du propulseur située au-dessus du niveau de l'eau, ainsi qu'un goulot pouvant tre fermé par un bouchon et destiné à permettre l'aspiration de l'eau qu'elle contient ou de verser dans cette eau un produit de désinfection. It consists of a waterproof envelope in the form of a bag threading over the submerged mechanical parts of an articulated propeller of the "Z-DRIVE" type or of an outboard motor so as to isolate them from the aquatic environment, this envelope having an opening edge allowing it to be fixed in a sealed manner on a part of the propellant situated above the water level, as well as a neck which can be closed by a plug and intended to allow the suction of the water in it or pour a disinfectant into it.
Sur les dessins annexés, donnés à titre d'exemples non limitatifs de formes de réalisation de l'objet de l'invention :
la figure 1 représente une enveloppe de protection en coupe verticale,
la figure 2 est un agrandissement du détail D de la figure 1
les figures 3 et 4 montrent, vue de côté en élévation, la partie externe d'un propulseur de type"Z
DRIVE"respectivement nue et recouverte d'une enveloppe de protection
et les figures 5 et 6 représente dans les mmes conditions un moteur hors-bord.In the appended drawings, given by way of nonlimiting examples of embodiments of the subject of the invention:
FIG. 1 represents a protective envelope in vertical section,
Figure 2 is an enlargement of detail D of Figure 1
Figures 3 and 4 show, in side view in elevation, the external part of a "Z type propellant
DRIVE "respectively naked and covered with a protective envelope
and FIGS. 5 and 6 show, under the same conditions, an outboard motor.
Le dispositif, figures 1 à 6, est constitué d'une enveloppe 1 étanche ouverte en haut et déterminée pour contenir les parties immergées du moteur hors-bord 2 ou de la partie externe du système"Z-DRIVE"3. The device, FIGS. 1 to 6, consists of a sealed envelope 1 open at the top and determined to contain the submerged parts of the outboard motor 2 or of the external part of the "Z-DRIVE" system 3.
Cette enveloppe, réalisée en toile plastifiée, ou en film synthétique souple suffisamment résistant, a la forme générale d'un sac dont le bord libre de l'ouverture comporte un bourrelet 4 pouvant tre serré de manière étanche sur une partie du propulseur 2,3 située au-dessus du niveau de l'eau, afin de maintenir la protection en place durant le temps nécessaire. This envelope, made of plasticized canvas, or of flexible synthetic film which is sufficiently resistant, has the general shape of a bag, the free edge of the opening of which comprises a bead 4 which can be tightly tightened on a part of the propellant 2,3. located above the water level, to keep the protection in place for the necessary time.
Ce bourrelet pourra avantageusement tre constitué d'un fourreau 5 circulaire exécuté dans le matériau de l'enveloppe 1 et contenant un anneau élastique 6 ou une corde dont les deux extrémités sortent du fourreau pour pouvoir tre nouées. This bead can advantageously be made up of a circular sheath 5 executed in the material of the casing 1 and containing an elastic ring 6 or a cord the two ends of which come out of the sheath in order to be able to be knotted.
Dans le cas du propulseur de type"Z-DRIVE"3, l'enveloppe 1 est dessinée pour que le bourrelet 4 soit derrière le rebord de la platine 7 de fixation du"Z
DRIVE"3 au bateau 8, de manière à protéger le soufflet 9 recouvrant l'articulation du système.In the case of the "Z-DRIVE" type propellant 3, the casing 1 is designed so that the bead 4 is behind the edge of the plate 7 for fixing the "Z
DRIVE "3 to the boat 8, so as to protect the bellows 9 covering the articulation of the system.
Un goulot 10 communicant de façon étanche avec l'intérieur de l'enveloppe 1 sera avantageusement prévu en partie haute de la protection, près du bourrelet 4 de façon à se trouver hors d'eau. Ce goulot, éventuellement pourvu d'un bouchon 11, est destiné à permettre d'introduire un tube pour vider 1'enveloppe une fois en place, en aspirant l'eau qu'elle contient, ou pour verser dans celle-ci un produit désinfectant tel que l'eau de javel. A neck 10 communicating in leaktight manner with the interior of the envelope 1 will advantageously be provided in the upper part of the protection, near the bead 4 so as to be out of water. This neck, possibly provided with a plug 11, is intended to allow the introduction of a tube for emptying the envelope once in place, by sucking up the water which it contains, or for pouring into it a disinfectant product. such as bleach.
Le dispositif pourra tre pourvu d'un tube d'aspiration 12 intégré se terminant à l'extérieur par un raccord 13 permettant de brancher un dispositif de pompage. The device could be provided with an integrated suction tube 12 terminating on the outside by a connector 13 making it possible to connect a pumping device.
Le positionnement des divers éléments constitutifs donne à l'objet de l'invention un maximum d'effets utiles qui n'avaient pas été, à ce jour, obtenus par des dispositifs similaires. The positioning of the various constituent elements gives the object of the invention a maximum of useful effects which had not, to date, been obtained by similar devices.
