Definitions
- the present invention relates to a device for protecting a boat hull against shocks, comprising an inflatable para-threshing element, as well as the method of installing this protective device on a boat and a boat equipped with this device.
- a first known type of protection device comprises a fender element in the form of a semi-rigid vertical tube, held suspended by a rope secured, for example to the rail.
- These tubes initially stored in the boat, must be put in place manually when docking and then stored when moving at sea or in the river. This manipulation is tedious and dangerous, and these socks are also very bulky when not in use.
- a second type of protective device is known, which makes it possible to overcome these drawbacks, and which is described for example in French patent application FR 2 916 733.
- This device comprises a fender element, which is connected to a means of inflation/deflation and which in the deflated state is housed in a box fixed to the deck of the boat.
- This device comprises a means for maneuvering in translation adapted to move the inflatable fender element, in the deflated state, between an internal position inside the box and an external position outside the box.
- This fender element is inflated once it has been positioned outside the box, and this fender element is deflated before being put back in place inside the box. Once inflated, the fender element forms a vertical sausage.
- This second known type of protection device has several drawbacks.
- the means for maneuvering in translation complicates the realization of this device and can be detrimentally subject to mechanical failures.
- to protect the hull of a boat against shocks it is in practice necessary to use a sufficient number of protective devices, by distributing them along the hull, with spacings between fender elements. which in practice are important. In practice, when they are too large, these spacings between fender elements reduce the effectiveness of the protection of the hull against impacts. It is possible to limit this disadvantage by increasing the number of fender elements, so as to reduce the spaces between fender elements, but this detrimentally increases the cost of implementing the protection.
- a third type of protection device is known, which is described for example in European patent application EP 0 987 176 and which consists in fitting, in the wall of the hull of the boat, a housing in which a protective element can be housed. -inflatable threshing.
- Each inflatable fender element is connected to a pneumatic circuit, which on the one hand allows the fender element to be inflated, in the form of a sphere, by blowing air directly inside the fender element and so as to deploy the fender element outside its housing, and which on the other hand allows deflation of the fender element allowing the fender element to be fully retracted into its housing .
- This third type of protection device advantageously makes it possible to simplify the operations of setting up and storing the fender element by avoiding tedious manipulations and can be managed remotely, but nevertheless has the same disadvantage than the second type of protection device with regard to the spacing between the fender elements.
- a fourth type of device for protecting a boat hull is known, which is described for example in German patent application DE 195 48 836 A1 and which comprises a box comprising an oblong opening and a fender element.
- This fender element comprises an envelope which is inflatable in the form of an “accordion” cushion. In the deflated state, this envelope is housed inside the box. This envelope is inflated to form an “accordion” cushion by blowing air directly inside the envelope.
- This solution can advantageously be implemented regardless of the orientation of the oblong opening, and in particular with oblong openings which can be oriented horizontally or vertically.
- the oblong opening must be wide enough to allow the inflatable tube to pass when it is inflated and to allow the accordion-shaped tube to retract inside the box when it is deflated.
- the width of this opening must necessarily be large, which leads to the mechanical weakening of the hull of the boat and harms the aesthetics of the boat. .
- the present invention generally aims to provide a new technical solution for protecting the hull of a boat against shocks, by means of an inflatable fender element.
- the invention aims to propose a new device for protecting the hull of a boat against shocks, which comprises an inflatable fender element, which makes it possible to simplify the operations for fitting and removing the fender element and to avoid tedious manipulations.
- the invention proposes a new device for protecting the hull of a boat against shocks, which comprises an inflatable fender element, which can be adapted to any type of boat.
- the invention proposes a new device for protecting the hull of a boat against shocks which, in a manner comparable to the solution of the German patent application DE 195 48 836 A1, can be implemented regardless of the orientation, in particular vertical or horizontal, of the opening of the box, but which, unlike the solution of German patent application DE 195 48 836 A1, weakens the hull of the boat less and can advantageously be implemented with an opening in the form of a narrow slot and is robust.
- the first object of the invention is thus a device for protecting a boat hull which has the following technical characteristics.
- This device for protecting a boat hull comprises a casing which comprises an opening in the form of a slot, and a fender element which is inflatable and fixed to the casing; the fender element comprises an envelope, flexible and impermeable, forming in the deflated state a pocket which is housed inside the box, the outer face of which delimits, with the box, a chamber which is connected or is adapted to be connected to inflation/deflation means; said bag in the deflated state is adapted on the one hand to be deployed outside the box by passing through the opening in the form of a slit and turning over, under the action of air blown under pressure into said chamber and to be inflated outside the box in the form of an elongated tube which extends in length parallel to the longitudinal axis of the opening in slot-shaped, so that after deployment and inflation of said envelope outside the box, said outer face of the deflated pocket forms
- the elongated bead which extends in length opposite the slot-shaped opening advantageously has a diameter greater than the width of the slot-shaped opening of the casing, and more particularly a diameter which may be much greater than the width of the slot-shaped opening of the casing. It is thus possible to implement an opening in the form of a slit, which can advantageously be very narrow, while allowing the implementation of an elongated tube which has, in the inflated state, a sufficiently large diameter to provide effective and robust protection against shocks.
- protection devices of the invention can advantageously be implemented on a boat, being distributed over the length of the boat with a small, or even non-existent, spacing between the elongated tubes.
- the protection device of the invention may also include the following optional technical characteristics, taken in isolation or in combination:
- the inflated tube forms a straight cylinder
- the length (L 2 ) of said bead in the inflated state is greater than the length (L 1 ) of the slot-shaped opening; preferably, when the envelope returns to the deflated state inside the box, passing through the slot-shaped opening, its two ends fold up; conversely, during the inflation of the casing of the fender element, when the casing leaves the box, it preferably unfolds at its ends under the effect of the air pressure and we obtain thus advantageously an inflated tube whose length is greater than the length of the slot-shaped opening.
- the interior volume of the box housing the fender element in the deflated state extends in length, in the direction parallel to the longitudinal axis of the slot-shaped opening, over a length (L ) less than the length (L 2 ) of said bead.
- the inner volume of the box housing the fender element in the deflated state has a height (H), which is measured parallel to this plane (P) of the slot-shaped opening and in the perpendicular direction to the longitudinal axis of the slit-shaped opening and a width (d), which is measured perpendicular to this plane (P) of the slit-shaped opening; said box height is greater than the diameter of said inflated tube and said box width is less than the diameter of said inflated tube.
- the fender element in the deflated state occupies almost the entire interior volume of the box.
- the part of the casing, which is opposite the slit-shaped opening, has a concave curved internal face inside the casing.
- the tube in the inflated state hides the through opening in the form of a slit over the entire length of said through opening.
- the flexible and impermeable casing of the fender element is fixed to the box around the periphery of the slot-shaped opening, preferably with sealing around the entire periphery of the slit-shaped opening.
- the closure means comprise a sliding door.
- Another object of the invention is a method for installing on a boat at least one protection device referred to above, during which a through opening, in the form of a slot, is made in a wall of the hull of the boat, and the casing of the protective device is fixed inside the hull, so as to position the slot-shaped opening of said casing opposite said through opening in the wall of the hull and to allow the deployment of the envelope of the fender element of the protection device, through the hull wall and outside the hull.
- the through opening in the form of a slit can be horizontal.
- the protective device of the invention can advantageously be installed on a boat, so that its elongated flange is oriented horizontally, which makes it possible to increase horizontally the extent of the zone of the hull which is protected against shocks, and consequently advantageously makes it possible to reduce the number of devices.
- the through opening in the form of a slit may not be horizontal, and may for example be vertical.
- the casing of a protective device is fixed inside the hull, so as to position the slot-shaped opening of the casing of the protective device opposite said corresponding through opening in the wall of the hull and to allow the deployment of the casing of each fender element through the wall of the hull and outside shell.
- the spacing between two through openings in the wall of the hull is provided so that the envelopes of the fender elements are able to be inflated outside the hull, being aligned end to end. tip, with no space between the envelopes of the fender elements.
- Another object of the invention is also a boat comprising a hull wall in which is made at least one through opening in the form of a slot.
- the boat is equipped with at least one of the aforementioned protective devices.
- the casing of the device is fixed inside the hull, so as to position the slot-shaped opening of the casing of the protection device opposite said through opening in the wall of the hull and to allow the deployment of the casing of the fender element of the protection device through the hull wall and outside the hull.
- the boat may also include the following optional technical characteristics, taken individually or in combination:
- the wall of the hull comprises at least at least two through openings in the form of slots, preferably in the form of horizontal slots, which are aligned and spaced from each other, said boat being equipped, for each through opening, a protection device referred to above; the casing of each protection device is fixed inside the shell, so as to position the slot-shaped opening of the casing of the protection device opposite said corresponding through opening in the wall of the shell and to allow the deployment of each fender element, through the hull wall and outside the hull.
- the spacing between two through openings in the hull wall is provided so that the fender elements are able to be inflated outside the hull, being aligned end to end, with no space between the elements fenders.

- a protection device 1 comprises a box 10, which has an opening 101 in the form of a rectilinear slot, of length L 1 , and of width d 1 , and an inflatable fender element 11 .
- This slit-shaped opening 101 defines an opening plane P ( Figure 3).
- the protective device 1 When the protective device 1 is mounted on the wall of the hull of a boat, its casing 10 is preferably oriented such that the longitudinal axis of the slot-shaped opening 101 is oriented horizontally, the plane P of the opening 101 in the form of a slit which can be vertical or slightly inclined with respect to the vertical. More particularly, in the particular example illustrated, the box 10 is of substantially parallelepiped shape and delimits an interior volume which serves as a housing for the fender element 11 in the deflated state. This interior volume has a length L (FIG. 1) measured in the direction parallel to the longitudinal axis of the slot-shaped opening, a height H (FIG.
- this box 10 comprises a front wall 100a, a rear wall 100c, a bottom wall 100b, an upper wall 100d and two side walls 100e. These walls delimit an internal volume in which the fender element 11 can be housed when it is deflated (FIG. 3).
- the slot-shaped opening 101 is provided on the front face of the box 10, preferably in the upper part of this box 10a More particularly, in the embodiment of FIG. 3, this slot-shaped opening 101 extends in width (di) between the upper wall 100d and the upper edge of the front wall 100a and in length (L 1 ) between the two side walls 100e.
- the inflatable fender element 11 comprises a flexible and impermeable casing 110, of small thickness, which is fixed to the box 10 on the periphery of the opening 10 by any suitable fixing means.
- This envelope 110 is for example made from a coated fabric, having for example a thickness of the order of a millimeter.
- the fixing of the casing 110 on the periphery of the opening 101 is carried out with a seal between the box 10 and the casing 110 over the entire circumference of the opening 101 in the form of a slit, in order to prevent air leaks into the chamber 12 during the inflation/deflation of the fender element 11 .
- the upper edge of the front wall 100a of the casing 10 and the front edge of the upper wall 100d are folded outwards, so as to form two projections 102 on the front face of the casing 10, for fixing the casing 110 of the fender element 11 .
- the casing 110 of the inflatable fender element 11 is fixed on its two front projections 102, by any appropriate fixing means.
- This fixing of the casing 110 can for example be carried out by means of a fixing frame (not shown in the figures), which is fixed on the two projections 102, by screws, bolts or rivets, and which clamps an edge folded 110a of the casing 110 against the front projections 102 and the front edges of the two side walls 100e, in a sealed manner over the entire circumference of the opening 101 of the box 10.
- a fixing frame (not shown in the figures), which is fixed on the two projections 102, by screws, bolts or rivets, and which clamps an edge folded 110a of the casing 110 against the front projections 102 and the front edges of the two side walls 100e, in a sealed manner over the entire circumference of the opening 101 of the box 10.
- the inflation/deflation chamber 12 (FIG. 3) is intended to be placed under overpressure or under depression, in order respectively to allow the deployment and inflation of the fender element 11 outside the box 10, in the form of a 'a protective bead 11', of elongated shape, and preferably cylindrical (configuration of Figures 4 and 5) or the deflation and retraction of the fender element 11 into the box 10 (configuration of Figures 1 to 3) .
- the fender element 11 is entirely housed inside the box 10 (with the exception, only in the particular example illustrated, of its folded edge 110a for its attachment to the box ).
- the casing 110 of the fender element 11 forms, in the deflated state, a deflated pocket 11′′, which is housed inside the box 10, the face of which 110a delimits, with the internal face of the walls 100a, 100b, 100c, 100d, 100e of the box 10, said inflation/deflation chamber 12, and which is adapted to be deployed outside the box by turning over and passing through the slot-shaped opening 101 ( Figure 3 ⁇ Figure 5), when the chamber 12 is pressurized.
- said external face 110a of pocket 11' thus forms the internal face of said bead 11'.
- the box 10 has two tubular connectors 103, which communicate with said internal chamber 12, through the bottom wall 100b of the box.
- the number of tubular connectors 103 and their position on the box 10 does not limit the invention. In another variant, it is possible to provide a single tubular connector, for example centered on this bottom wall 100b. In another variant, it is possible to provide more than two tubular connectors 103, and/or one or more tubular connectors 103 can be positioned at the level of the rear wall 100c of the box 10 and/or of one or the other of its side walls 100d.
- tubular connectors 103 are used to connect the inflation/deflation chamber 12 to inflation/deflation means 14, by means of flexible pipes 13.
- the inflation/deflation means 14 comprise, for example, an air compressor 140, with an additional supply of compressed air, associated with a vacuum pump 141, as well as a distributor making it possible to connect the protection device 1, either to the compressor for inflating the fender element 11 , or on the vacuum pump for deflating the fender element 11 .
- These inflation/deflation means 14 will advantageously be housed in another box fixed to the deck of the boat. These inflation/deflation means 14 can be connected to several other protection devices 1, so that they can also be used for the simultaneous or sequential inflation of all the fender elements 11 of these protection devices or the simultaneous deflation or sequentially of all the fender elements 11 of these protection devices 1 .
- the compressor 140 is connected to the inflation / deflation chamber 12, and the compressor 140 is started so as to blow air A under pressure in the chamber 12, which makes it possible to place the chamber 12 under overpressure.
- This overpressure causes the deployment of the casing 110 of the fender element 11 outside the box, causing it to pass through the opening 101 in the form of a slit, then the inflation of the casing 110 of the fender element 11 so as to form, outside the box 100, the cylindrical flange 11' (FIG. 5).
- This bead 11 extends in length parallel to the longitudinal axis of the opening 101 in the form of a slit (FIG. 4) and has in the inflated state a length l_2 and a diameter d 2 which is greater than the width of the slot-shaped opening 101 of the box 10.
- the air pressure implemented in the chamber 12 during inflation must of course be sufficient to cause the fender element 11 to come out by passing it through the narrow opening 101, in the form of a slit, and to inflate said fender element 11 outside the box 10 and form said flange 11'.
- the compressor 140 When the tube 11' is inflated, the compressor 140 is stopped and the supply circuit of the chamber 12 is sealed off, for example by means of a solenoid valve, so as to maintain the pressure in the chamber 12, this which makes it possible to maintain the tube 11' in the inflated state.
- the envelope 110 of the fender element 11 may not be elastically deformable, so that the inflation of the fender element 11 leads to an increase in volume of this fender element 11, without elastic deformation of the envelope.
- the envelope 110 of the fender element 11 may also have a certain elasticity, so that the inflation of the fender element threshing 11 can in this case result in an increase in volume of this fender element 11 with a more or less significant elastic deformation of the envelope 110.
- the vacuum pump 141 is connected to the inflation/deflation chamber 12, and the vacuum pump 141 is switched on so as to create a vacuum.
- the internal inflation/deflation chamber 12 which makes it possible to extract by suction and in a forced manner the air contained in this chamber 12, and automatically causes the deflation and the suction of the fender element 11. That -it deforms and automatically enters the interior of the box 10, passing through the opening 101 in the form of a slit, until the final configuration of Figure 3, in which the fender element 11 is completely deflated.
- the envelope 110 of the fender element 11 has a length greater than the length of the opening 101 in the form of a slot in the box.
- this envelope 110 returns in the deflated state inside the box 10, passing through the opening 101 in the form of a slit, its two ends fold up.
- the fender element 11 is inflated, when the casing 110 is taken out of the box, it unfolds at its ends under the effect of the air pressure. A bead 11' is thus advantageously obtained, the length L 2 of which (FIG. 2) is greater than the length L 1 of the opening 101.
- All these inflation or deflation operations can preferably be controlled automatically by means of an electronic control circuit, implemented for example by means of a programmable logic controller or equivalent.
- the depression implemented in the internal chamber 12 is preferably sufficient on its own to deflate and bring the fender element 11 inside the box 10.
- These elastic return means comprise for example one or more elastic tensioners which are positioned in the box 10 and connect the fender element 11 to the box 10.
- the box 10 When the protection device 1 is fixed to a wall of the hull of a boat, it is preferable for the box 10 to take up as little space as possible, at least in the horizontal and transverse direction to this wall. For this reason, in the preferred embodiment of the appended figures, the width d of the box 10 is advantageously less than the height H of the box 10.
- the width d of the box 10 is less than the diameter d 2 of the flange 11' and the height H of the box 10 is greater than the diameter d 2 of the flange 11'.
- the fender element 11, once deflated and retracted into the box 10 forms a narrow pocket 11” (FIG. 3) of width less than the diameter d 2 of the flange 11′ and of height greater than the diameter d 2 of the 11' sausage.
- the length L of the box 10 is less than the length L 2 of the said bead 11' in the inflated state (FIG. 4).
- this 11” pocket occupies almost the entire interior volume of the box 10.
- the part 10Of of the casing 10 which is located vis-à-vis the opening 101 in the form of a slit, has, inside the casing 10, an internal face 100g concave curve, especially with an arc profile.
- This curved and concave internal face 100g allows better guidance of the fender element 11 and thus facilitates the exit of the fender element 11 outside the box 10 and the introduction of the fender element 11 into box 10.
- the protection device 1 comprises a hatch 15, which is movable between a closed position (FIGS.
- This hatch 15 is preferably a sliding hatch.
- the box 10 in order to guide the sliding door 15 in translation, can for example be equipped with two guide rails 16a, 16b spaced vertically, and comprising a rectilinear front portion, which extends on the front face of box 10, a rectilinear rear part which extends from the rear face of box 10, and at least one curved connecting portion, in the shape of an arc of a circle, which connects the rectilinear front and rear portions, so to form a U-shaped guide path.
- the sliding door 15 is in this case for example a flexible strip positioned and guided in translation in the guide rails 16a and 16b.
- the device 1 comprises for example (FIG. 3) a rotary drive roller 17, which is actuated by an electric motor (not shown) and which allows the door 15 to be driven in translation in one direction or the other.
- the longitudinal axis of this through opening 21 is oriented horizontally and for example parallel to the front/rear longitudinal axis of the hull of the boat.
- the casing 10 of the protection device 1 is fixed inside of the hull 2, so as (FIG. 7) to position the opening 101 in the form of a slit of the said box 10 opposite the said through opening 21 in the wall 20 of the hull 2 and to allow the deployment of the element fender 11 of the protection device, through the wall of the hull 2 and outside the hull 2 (FIGS. 8 and 9).
- the plane P of the opening 101 can be more or less vertical.
- the front wall 100a of the casing 10 is positioned close to the internal face 20a of the wall 20 of the shell 2, so that the two openings 101 and 21 in the form of a slot are sufficiently close one from the other.
- the width d 3 of the opening 21 in the wall 20 of the shell 2 can advantageously be less than or equal to the width di of the opening 101 of the box 1.
- the length L 3 of this opening 21 in the wall 20 of the shell 2 is slightly greater than or equal to the length L 1 of the opening 101 of the box 1.
- the opening 21 of the hull 2 is also closed by this hatch 15 and only the hatch is visible from the outside of the hull 2, which in particular confers a overall aesthetic appearance.
- the tube 11' in the inflated state advantageously makes it possible, thanks to its elongated shape and its horizontal orientation, to protect the hull 2 of the boat against shocks over a significant horizontal length and corresponding to the aforementioned length L 3 of the tube 11' .
- the opening 21 in the form of a slit in the wall 20 of the hull 2 can advantageously be very narrow (width d 3 low), which makes it discreet and in particular makes it possible not to damage the aesthetics of the boat, while by allowing the implementation of a bead 11 'which has in the inflated state a diameter (d 2 ) greater than the width d 3 of the opening 21 in the form of a slot, and in particular a diameter (d 2 ) sufficiently important to provide effective impact protection.
- an opening 21 of width d 3 which can be between 30mm and 50mm and a bead 11' which, in the inflated state, has a diameter (d 2 ) greater than 150mm, and for example of the order of 200mm.
- the length L 3 of the through opening 21 in the wall 20 of the shell 2 is less than the length L 2 of the bead 11 ', so that the two ends 21a of the through opening 21 are set back relative to the two end faces 11a of the tube 11' in the inflated state.
- this advantageously allows the bead 11' to hide the through opening 21 in the wall 20 of the hull 2 over its entire length.
- the invention is not limited to the implementation of an opening 21 in the form of a slit which is horizontal and of a protective bead 11 or 11' which, once inflated, is horizontal, but can also be placed implemented, as illustrated in the variant of Figures 12 to 15 or in the variant of Figure 16, with an opening 21 in the form of a slot which is not horizontal, and is for example vertical and with a protective bead 11, which once inflated, is not horizontal and is for example vertical.
- the orientation of the slit-shaped opening 21 and of the inflated tube 11 can be arbitrary and is not necessarily horizontal or vertical, and can for example, and non-limiting manner, be 45° from the vertical in the plane of Figure 12 or 14.
