Definitions
- the present invention relates to a protective device adaptable to any type of boat hulls, when these boats are afloat, whether at post or at anchor.
- the device creates a sealed structure around the entire hull of a ship, the sea water trapped between this structure and said hull being able to be expelled to the sea water of the port by emptying means.
- filling means allowing fresh water to be brought into the space between structure and hull, in order to rinse and clean the hull of the boat of the remaining salt or various stains.
- Document US-R-3,685,477 proposes a device for protecting the hull of a boat from marine soiling, when the boat is afloat in sea water.
- This device has a metal frame having a rear door.
- the frame is covered by an envelope made of a flexible and waterproof sheet which defines a space which envelops the boat.
- a rot-proof chemical is added to the space to prevent marine soiling on the boat's hull.
- the door and its means of attachment to the envelope are lowered to allow entry or exit of the boat in order to be protected.
- the flexible envelope is attached to the frame by unique means allowing movement of the sheet without the use of special tools, adhesives or mechanical fasteners.
- the document FR- ⁇ -2.536.363 relates to a process for protecting the hull of a boat against deposits due to the presence of animal or vegetable marine substances, during wintering, in which the hull is surrounded up to '' above the waterline using a waterproof and opaque cover stowed to the deck of the boat. The sea water located between the cover and the hull is then discharged and a pocket of fresh water is injected between the cover and the hull. The latter being protected from light and the marine environment, no unwanted deposit settles on it and the Jateau retains its speed qualities.
- Document EP-R-0.360.436 describes a method of protecting a boat hull which includes the development of a protective envelope around the hull and the treatment of trapped water to inhibit the action of organisms sailors.
- the envelope can be retracted to a space-saving position in which it occupies little space and where it is exposed at least to sea currents.
- the retraction and deployment are carried out by folding a frame or a support on which the envelope is mounted, and / or of the envelope itself.
- the trapped water is checked by a probe and the amount of treatment agent to neutralize marine life is determined. This precise quantity is added to the trapped water, and consequently the latter is made neutral with respect to the hull and it is likewise harmless for the environment when it is released during the shrinking of the envelope.
- document US-R-5,152,242 relates to an enclosure for protecting a hull for a boat afloat and stationary in a quantity of water included in the enclosure.
- a floating envelope constitutes a first partition having a shape which approximates the perimeter of the hull of the boat at the surface of the water. This envelope forms a continuous free space where the boat is placed.

- the present invention relates to a protection device
- the present invention relates to a protection device 1 intended to cover the entire hull 6 of a boat 3 and almost all of the hull 2 of this boat 3.
- This protection is essentially carried out to combat dirt from maritime waters 4 which constitute the surrounding environment of said boat 3.
- This protection device 1 is essentially constituted, as can be seen in FIG. 2, by a box 10 and an envelope of protection 5.
- This embodiment with variants is shown in all of Figures 1 to 9 attached.
- the protective envelope can circumscribe a larger volume and also include the box.
- the box will therefore be movable relative to the envelope, which is not the case in the figures.
- This embodiment, not shown allows for example, by emptying and successive repositioning of the box, to treat the entire hull of a boat.
- the embodiment of the protective device 1 consists of a box 10 which is secured to the protective casing 5 by means of attachment, not referenced, belonging to the public domain.
- the box has a particular shape which makes it possible to isolate, as can be seen in FIGS. 3 and 4, submerged mechanical elements 12 such as a motor, a rudder or the like.
- the box 10 Since these elements 12 are quite bulky, the box 10 has a free space 11 serving as an inspection well so that an authorized person can work on said elements 12. To achieve this result, it is necessary to set up, as seen in Figure 3, the protection device 1.
- the envelope 5 is present at the lateral levels of the boat 3 as well as at the level of its bow, while the box 10 is present at the stern of said boat 3.
- These means 9 are essentially constituted by a pump associated with a discharge element such as a pipe allowing the supply or the discharge of the water located in this space.
- the free space 11 will therefore allow a person to work on the mechanical elements 12 which are normally submerged while being dry while the boat 3 is afloat.
- the protective envelope 5 may include a structure in wavy relief 20, as shown in FIG. 6, which creates spaces that cannot be compressed by maritime waters 4 when the circumscribed waters have been evacuated.
- the protective envelope 5 is associated with a pipe 16 allowing the supply of fresh water coming from a tap 32, located on the quay, this fresh water being intended to replace maritime waters which were trapped, between the hull 6, on the one hand, and the casing 5 and the box 10 on the other hand, this for the purpose of complete rinsing, so that the elimination of salt water and soiling due to maritime waters 4 is as complete as possible.
- the fresh water passing through the pipe 16 can be projected into the space to be rinsed by means of projection means 17 constituted by holes 17.
- the protection device 1 When the protection device 1 is not used, that is to say say that the boat does not require protection or is in service, it 1 may be, as shown in Figure 5, sunk at the bottom of port 14, the device 1 remains in position at the bottom of said port 14, due to the presence of the handling means 7 which secure the device 1 on the one hand to a mooring ring 29, located on the quay, and on the other hand to a mooring 15, located at the bottom of the port 14, by the 'intermediary of a daughter chain 13, itself associated with a buoy 28 or a pendulum connected to the mother chain.
- the protection device 1 when the protection device 1 is put in place on the boat 3, as is the case in FIG. 3, the protective envelope 5 is held in position against the hull 2 of the boat 3 by by means of fixing means 8.
- These means 8 are constituted by tensioners, ropes, etc. or any means in the public domain.
- the casing 5 is ballasted by means of a mass located longitudinally and going from the bow to the stern under the boat 3. Nevertheless and all simply, the weight of the protective device 1 exerts a traction opposite to the mooring 15 or the force exerted by the pendulum.
- the upper part of the casing 5 has flexible slats *
- the box 30 is of modular construction. It has a number of elements.
- cowling 31 which can receive the emptying and filling means 9 as well as lower support arms 24 which can include protective elements 27 intended to follow the shape of the shell 2.
- lateral support arms 23, which constitute lateral stiffeners, intended to stiffen the attachment points of the casing 5 with respect to the entire width of the stern of said boat 3.
- these arms are replaced by lateral support wings 21 and lower support wings 22, these can also receive protective elements.
- These protective elements 27 are for example made of foam block of a density adapted to the pressures undergone. They can be made of neoprene blocks which are adapted to the supports according to the shape of the submerged shells 2 and are fixed on the wings 21 and / or 22.
- the box 10 or 30 includes a floor 25 or 26 which serves as a work plan for the person who will come to work in the free space 11 emptied of maritime waters 4.
- FIG. 9 finally, an embodiment with two free spaces is presented.
- This embodiment is particularly suitable for boats with two inboard engines.
- the box can be constituted by a frame covered by a flexible and reinforced canvas.
- the box can be detached from the protective envelope, if it is equipped on its edges, constituting its immersed periphery, with a flange ensuring a total seal.
- the protective envelope can connect several boxes.
- the lateral support elements 21 and 23, placed on the side 12 of the hulls 2, and the lower support elements 22 and 24, placed under said hulls 2, boxes 10 and 30 constitute locking arms in position of said boxes 10 and 30 relative to the hulls 2 of boats 3.
- the arms side 21 and 23 have a substantially vertical position, while the lower arms 22 and 24 have a substantially horizontal position, so that the concavity created between the arms 21 and 23, on the one hand, and 22 and 24, on the other part, facilitates the fixing of the boxes 10 and 30 on the shells 2.
- each box 10 or 30 which cooperates directly with a shell 2 can be equipped with a sealed flange which allows, once pressed against the shell 2 and that the box 10 or 30 is emptied, to create a free and dry space against said hull 2.
- the boat 3 is a sailboat, comprising a keel
- an opening is made in the protective envelope at the level from the keel.
- a second protective envelope not shown in the figures, has the shape of a sock which can contain said keel.
- the two envelopes are connected together, at the opening of the first envelope, by any means of fixing the public domain, for example a keel frame.
- a suction tube connected to the pump, allows the evacuation of the water present between the keel and the sock-shaped envelope.
- the two envelopes could constitute only one single envelope whose concave shape would be adapted to the convex shape of the hull of the sailboat.
