FR2826929A1 - Protective housing for marine outboard motor has rigid casing with seals to prevent ingress of water and discharge pumps to vent water - Google Patents

Abstract

The protective housing for a marine outboard motor or motor propeller shaft has a rigid casing (1) for enclosing the motor below the hull or water line on bases (8,9). The casing has gaskets (6,7) to seal the housing and prevent the ingress of water. Water is discharged by pumps to keep the normally immersed part of the motor (3) dry.

Description

<Desc / Clms Page number 1>

The present invention relates to a protective base adaptable to any type of motor boat (s) whose supports, allow the installation flat, of a locking device of a rigid or flexible box or bars of joints. More particularly, the device creates a sealed structure around the motor bases or the lines of shafts when these are trapped inside the protective base (box).

ce volume soit souple ou rigide Une fois l'eau vidée, il est possible, dans le cas d'un caisson rigide de rincer les embases du moteur ainsi que le circuit de refroidissement, à l'eau douce, en remplissant à nouveau le caisson et en faisant tourner le moteur au ralenti, au point neutre. The engine bases, the propeller (s), the rows of shafts being trapped, one or more pumps drain the water from the volume integrating them; that

this volume is flexible or rigid Once the water has been emptied, it is possible, in the case of a rigid box, to rinse the engine bases and the cooling circuit, with fresh water, by filling the box again and by idling the engine at neutral.

 The dirt removed, diluted in the moving water, volume, one or more internal or external pumps evacuate the liquid leaving the bases, the propellers, the cooling circuit, the hinges etc in excellent state of cleanliness.

 Traditionally it is customary in the marine world to take a boat out of the water to clean the hull, the engine bases and repaint with anti-fouling paint the elements which are continuously submerged.

 There are manipulated or automatic processes which, using pressurized jets, make it possible to clean the submerged parts of boats.

Aucun procède connu a ce jour ne permet i isolation totale de la seule partie des embases de moteur immergées à partir d'un dispositif à pression
Le document US-A-3. 685.477 (Wood) propose un appareil de protection de la carène d'un bateau dans sa totalité et ne peut se comparer au présent dispositif déposé. There is a process according to which a total structure of the boat hull can be isolated thanks to the installation of a rigid box married to a tarp going up on the freeboards.

No process known to date allows total isolation of the only part of the motor bases immersed from a pressure device.
Document US-A-3. 685.477 (Wood) offers a device for protecting the hull of a boat as a whole and cannot be compared to the present device.

 Document FR-A-2.536. 363 (Magmer) relates to a process for protecting the hull of a boat during wintering and cannot be compared to the present device removed.

The same applies to the device deposited in document EP-A-0. 360.436 (Morisson) which also describes another hull protection process
Document US-A-5. 152.242 (Bradley) has for its object an enclosure for protecting a hull for a boat afloat and stationary in a quantity of water included in the enclosure which cannot be compared to the present device deposited.

Document FR-A-490 182 (Drosso) also speaks of protecting a total hull from a tarpaulin which is unrolled
The document FR-A-485 241 (ACMCHA) comes closest to the invention, however the use of straw by air or water pressure makes it different.

possible avec l'invention Le document US92/06201 (Eichert) isole la carène en totalité et n'a rien à voir avec l'invention
Les documents FR-94 12697 et FR95/01363 (Penalba) se rapprochent de l'invention mais se trouvent être simplifiés et dépassés par la technique présentement déposée suite aux recherches effectuées in-situ, en effet s'il apparaissait évident de décrire des boudins étanches pour isoler le caisson de la coque, aucune technique précise ne permettait cependant de concrétiser cette étanchéité. Nous verrons qu'avec le savoir faire, il est apparu que la coque devait recevoir un ou plusieurs éléments mécaniques fixes pour assurer l'étanchéité tant

désirée, d'où la présente invention. Hormis cette dernière référence, l'ensemble de ces documents propose une enveloppe souple qui circonscrit un espace d'eau où le bateau vient prendre place. GB-A-128 358 (DE Meuter) isolates the hull but cannot be compared to the invention
Document FR-A-463 148 (Jameson) isolates this hull without comparison

possible with the invention Document US92 / 06201 (Eichert) isolates the entire hull and has nothing to do with the invention
The documents FR-94 12697 and FR95 / 01363 (Penalba) come close to the invention but are found to be simplified and exceeded by the technique presently filed following research carried out in situ, indeed if it appeared obvious to describe tubes waterproof to isolate the box from the hull, no precise technique made it possible to achieve this tightness. We will see that with the know-how, it appeared that the hull had to receive one or more fixed mechanical elements to ensure the tightness as

desired, hence the present invention. Apart from this last reference, all of these documents propose a flexible envelope which circumscribes a water space where the boat comes to take place.

pour efficace qu'il soit, ventes nombreuses, ne permet pas l'étanchéité de la seule protection des embases moteurs à partir d'un seul caisson, sans bâche.. Le problème de l'étanchéité s'étant toujours posé ; la présente invention par son dispositif vient mettre un terme à ce manque de service. The object of these inventions is always to reduce the dirtying effects of maritime or river waters, either by adding treatment substances or by complete partitioning of these trapped waters. However, these techniques do not allow part of the hull or submerged mechanical elements to be exposed to the air, in order to maintain or repair them, without the boat having left the surrounding sea waters, only the latest Penalba patent. above allows this possibility but the device

efficient as it is, numerous sales, does not allow the sealing of the only protection of the motor bases from a single box, without tarpaulin. The problem of sealing having always arisen; the present invention by its device puts an end to this lack of service.

 To this end, said invention relates to a basic device for protecting engine bases onboard or outboard, from the attack of the waters surrounding the boat.

 The boat being afloat, stationary or at anchor, the device is integrated in a flexible or rigid volume intended to trap the engine bases located and fixed on the transom of the boat.

<Desc / Clms Page number 3>

 The technical problem which arose for a watertight insulation of the boxes is that a part of these boxes, permanently submerged the foreseeable infiltration of water slowed down any idea of dryness of the bases. This is the reason why a patent provides for the 'total isolation of the boat from a box to which a tarpaulin was stuck, without the tarp this could not be done (Pénalba above).

The solution had to be simple to be effective and inexpensive.

adaptée, avec des pattes larges vient se visser, se boulonner ou se couler dans de la résine pour constituer une base solide d'impact sous pression ; Des ergots de guidage et de fixation traversant ou non ledit tableau font corps avec la carène, sur le coté extérieur du tableau arrière, l'armature du caisson portant le joint vient s'appliquer après manipulation contre ce tableau. Dés lors, en rabattant les boucles de fermetures, leviers, sur les ergots de la carène, la pression du joint étanchéifie le caisson que l'on peut vider de son eau. On the transom of the boat, inside the boat, a shaped plate

adapted, with wide legs is screwed, bolted or run in resin to form a solid base of impact under pressure; Guide and fixing lugs, whether crossing said panel or not, form one body with the hull, on the outside of the rear panel, the frame of the box carrying the seal is applied after manipulation against this panel. Therefore, by folding the closure loops, levers, on the pins of the hull, the pressure of the seal seals the box that can be emptied of its water.

The edge of the box which integrates the sealing device ends with a seal which is applied on a perimeter defined on the transom around the bases.

 This armored joint engages on a submerged lug fixed on the boat, under the base, at an angle and / or horizontally.

 The whole box switches from bottom to top or from the side thanks to manipulation, straightening up, helped by a guide or small telescopic arms which can be placed on the transom of the boat or on a part of the engine. There, the joint of the box touches the transom and joins one or more other hooks with loops fixed on the emerged part of the array, above the base. The loop (s) is / are folded (s) against the wall of the table or the box, depending on the embodiment, by means of a movable lever; The seal can now seal.

 On the upper part of the box which can be without cover, a device allows the emptying of salt or dirty water, then the filling with clean water to allow the cleaning of the mechanical parts. This water is then evacuated and the engine alone finds itself dry for wintering, month, week, night.

 According to a first embodiment, the box (es) can be rigid with integrated emptying and filling systems.

According to a second embodiment, the boxes can be flexible with a ballast (socks).

 According to a third embodiment, the box (es) can be carrier (s) or guide (s) of a fixed or mobile seat allowing small repairs to be made to the rear of the engine.

 According to a fourth embodiment, one of the internal panels can have an additional sealing plate which can close according to a

 second safety, the engine passage hole on the transom, if the engine is removed for repair while the boat remains afloat.

il n'est pas obligatoire que la chaussette soit termee sur la partie supeneure, un capot peut être envisagé ou même tout simplement un taud ou une bâche à clipser. Whatever the embodiment, the box or the sock (s) are connected by ends to the rings of the berth or to the daughter chains or to the boat by means of fasteners.

it is not compulsory that the sock is finished on the upper part, a hood can be envisaged or even quite simply a awning or a tarpaulin to be clipped.

 The interior of the rigid box is reinforced if necessary, by stiffeners.

 On the outside of the rigid box there can be a hanging system allowing the addition of another box intended to accommodate a mechanic so that the latter can work afloat, engine dry.

 Similarly there can be a hanging system to attach or join two boxes together supposed to dry two engines of the same boat.

Afin d'éliminer toute pression excessive sur le tableau arrière, il peut y avoir des bras de stabilisation, en immersion, venant se glisser à partir du caisson, sous la coque. Inside the box, sock, there may be diluents of periodic maintenance products

In order to eliminate any excessive pressure on the transom, there may be stabilization arms, immersed, sliding from the box, under the hull.

De même si un mécano prévoit la mise en place d'une platine de caisson, a A. s A r

a not, 11 peur passer un ooucim goniiaoie sous la coque arrière au bateau, gonfler ce boudin pour faire sortir en totalité l'embase du moteur immergé, faire les adaptations mécaniques souhaitées (mise en place des ergots, charnières etc) étanchéifier le tout et dégonfler le boudin dés lors que le caisson peut être reçu. Le caisson semi-rigide peut se transformer en barrette semi-rigide, barrette sur laquelle vient se fixer de façon étanche, une bâche. Cette barrette se fixe alors sur la carène grâce à des platines appliquées à partir des arbres d'hélices sous forme de tiges ou de crochets coulés dans la coque par le constructeur. Un plongeur passe les barrettes dans ces platines ou ergots et rabat des petits leviers intégrés aux barrettes. Ces barrettes se plaquent contre la coque à la façon de barrettes de seuils vissées sur le bas de portes d'appartements pour éviter les courants d'air ; II n'y a plus qu'à vider l'eau prisonnière de la bâche. Ladite bâche se plaque sous la pression externe de l'eau de mer environnante, le vide étant créé. To fill the box (sock) the simple fact of unbuckling the lugs is enough to cancel the waterproofing and the box sinks. There may be if the need arises a drain valve.

Similarly, if a mechanic plans to install a box plate, a A. s A r

The semi-rigid box can be transformed into a semi-rigid bar, a bar on which a waterproof cover is fixed. This bar is then fixed on the hull thanks to plates applied from propeller shafts in the form of rods or hooks poured into the hull by the builder. A diver passes the bars through these plates or lugs and flaps small levers integrated into the bars. These bars are pressed against the hull like threshold bars screwed on the bottom of apartment doors to avoid drafts; It only remains to empty the water trapped in the tarpaulin. Said cover is pressed under the external pressure of the surrounding sea water, the vacuum being created.

The propeller shafts and all submerged elements are found dry. This

 device can also be applied to isolate the submerged hulls, in their entirety.

 The attached drawings are given as indicative and non-limiting examples. They represent different preferred embodiments according to the invention. They will allow the invention to be easily understood.
