Description
- Mechanism for positioning a movable part relative to a support, between a deployed position where the movable part is at a distance from the support and a retracted configuration where the movable part is located flush with the support, and seafaring vehicle including such a mechanism
- The invention relates to the adjustment in position, along several directions, of a movable part with respect to a support.
- In particular, the invention relates to a mechanism for positioning a movable part relative to a support, between a deployed position where the movable part is at a distance from the support and a retracted configuration where the movable part is located flush with the support.
- The invention also relates to a seafaring vehicle, such as a vessel, including such a positioning mechanism
- It may consist for example of a bulwark that is movable with respect to a hull of the seafaring vehicle.
- Seafaring vehicle is understood here to mean a boat or a vessel which allows the maritime transport of materials and/or people. It may consist of any type of boat, particularly a pleasure, fishing, commercial boat, etc., whether it is a motor and/or sail boat.
- In the maritime field, some vessels include a hull and a bulwark which can be movable relative to the hull, between a deployed configuration wherein the bulwark is at a distance from the hull and a retracted configuration wherein the bulwark is flush with the hull.
- For example, the
European patent EP 3 290 326 B1 discloses a movable bulwark coupled by a mechanical hinge system to the hull of a boat. - Such a mechanical hinge system can take on play in use, especially given that a bulwark is a relatively heavy part. This mechanical hinge system, which requires an adjustment at the assembly thereof, must generally be disassembled then replaced or re-adjusted by a maintenance operation.
- The invention relates to a mechanism for positioning a movable part relative to a support, which is particularly reliable and convenient to use.
- The invention thus relates, in a first aspect, to a mechanism for positioning a movable part relative to a support, between a deployed position where the movable part is at a distance from the support and a retracted configuration where the movable part is located flush with the support, including:
-
- a base mechanically attached in a fixed manner to the support and having a central hole;
- a first positioning device provided with a first body mounted in the central hole of the base and having a first off-centered hole relative to the central hole, and with a first notched wheel mechanically attached to the first body and configured to rotate the first body relative to the base when the first notched wheel is actuated;
- a second positioning device provided with a second body mounted in the first off-centered hole of the first positioning device and having a second off-centered hole relative to the central hole and non-concentric with the first off-centered hole, and with a second notched wheel mechanically attached to the second body and configured to rotate the second body when the second notched wheel is actuated;
- with the first positioning device and the second positioning device which are mounted fixed in translation relative to the base and which are configured to position, along a first direction and along a second direction different from the first direction, an interface member of the movable part which is mounted in the second off-centered hole of the second body of the second positioning device and which is mechanically attached to the positioning mechanism.
- In the mechanism according to the invention, the first positioning device and the second positioning device are each of the so-called eccentric type.
- The mechanism according to the invention thus offers the option of adjusting along two separate directions the movable part in position relative to the support, so as to make it possible, in the retracted configuration, to place the movable part flush with the support and, in the deployed configuration, to place the movable part at a distance from the support.
- The mechanism according to the invention has the advantage of enabling an easier adjustment by merely actuating the first notched wheel and/or the second notched wheel, so as to position the first positioning device and along the second direction via the second positioning device.
- Preferred, simple, convenient and economical features of the bearing according to the invention are described hereinafter.
- The first positioning device is provided with recesses arranged in the first body and with clamping jaws movably mounted in the recesses.
- The clamping jaws are configured to lock the second body of the second positioning device in position.
- The first positioning device is provided with a clamping collar mounted around the jaws and the first body and configured to hold the jaws in the respective recesses.
- The mechanism includes a cover which has a central orifice and which is mechanically attached to the base, with the central orifice which is located facing the central hole of the base, the first body of the first positioning device is rotatably mounted between the cover and the first body whereas the cover is at least partially sandwiched between the first notched wheel and the first body.
- The second body of the second positioning device passes through the central orifice of the cover and the first notched wheel of the first positioning device is located between the cover and the second notched wheel of the second positioning device.
- The base includes a main body which is provided with a curved elastic member arranged in the central hole, a radially through orifice of the main body, and a locking member at least partially inserted into the through orifice and configured to stress the curved elastic member.
- The curved elastic member is configured to lock the first body of the first positioning device in position.
- The curved elastic member is formed by a lug integral with the main body.
- The base includes a sole plate mechanically attached to the support and the main body is mechanically attached to the sole plate.
- The base is formed from one piece.
- The mechanism includes a first operating key configured to allow the rotation of the first notched wheel of the first positioning device and a second operating key configured to allow the rotation of the second notched wheel of the second positioning device.
- The invention also relates, in a second aspect, to a seafaring vehicle, including a positioning mechanism as described above and which is configured to adjust a movable part of the seafaring vehicle in position relative to a support of the seafaring vehicle, between a deployed position where the movable part is at a distance from the support and a retracted configuration where the movable part is located flush with the support.
- Seafaring vehicle is understood here to mean a boat or a vessel which allows the maritime transport of materials and/or people. It may consist of any type of boat, particularly a pleasure, fishing, commercial boat, etc., whether it is a motor or sail boat.
- In particular, the movable part can be a movable bulwark of the seafaring vehicle and the support can be a hull of the seafaring vehicle.
- Such an application makes it possible to create, in an open position of the bulwark, an additional surface for a user of the seafaring vehicle, while in a closed position of the bulwark, the latter is stored flush with the hull.
- The mechanism according to the invention makes it possible to position the bulwark perfectly flush with the hull in the closed position thereof, and adjustment is easier.
- Between the retracted position and the deployed position, or respectively the open position and the closed position of the bulwark, the latter is coupled around an interface member of the bulwark mounted in the second off-centered hole of the second body of the second positioning device.
- The mechanism is mechanically attached by the base to the hull of the boat and the bulwark is provided with a hinge axis about which it pivots, said hinge axis being inserted into the interface member.
- The interface member includes a support flange mounted on the mechanism and a ball joint attached to the support flange and which receives the hinge axis.
- The disclosure of the invention will now continue with the description of an exemplary embodiment, given hereinafter as an illustration and that is not limiting, with reference to the appended drawings.

third shoulder 62 of thesecond body 51 faces the second notchedwheel 65 and the fourthlateral wall 59 passes through the second off-centeredorifice 66. - The second notched
wheel 65 is therefore located overall facing the first notchedwheel 40, which are readily accessible. - The
mechanism 5 includes asecond operating key 69 equipped with a grippingportion 70 and anactuation portion 71 which is here curved and which is configured to allow the rotation of the second notchedwheel 65 of thesecond positioning device 50, thanks for example to aspigot 72 at the end of theactuation portion 71 which engages between two teeth of the second notchedwheel 65. - In the
mechanism 5 thus assembled, thefirst positioning device 20 and thesecond positioning device 50 are mounted fixed in translation relative to thebase 6 and are configured to position, along the first direction and the second direction (see hereinafter), thebulwark 3 in a particularly fine manner. - It will be noted that the clamping
jaws 28 are configured to lock thesecond body 51 of thesecond positioning device 50 in position. - With reference to
FIG. 21 , thehinge system 4 of thebulwark 3 is provided with aninterface member 80 which is configured to be mounted in the second off-centeredhole 52 of thesecond body 51 of thesecond positioning device 50 and is mechanically attached to thepositioning mechanism 5. - In particular, the

fastening member 83 is inserted on the side of thebase 6 of the mechanism whereas thesupport flange 81 projects at least partially from the side of the second notchedwheel 65. - The
interface member 80 furthermore includes a ball joint 84 engaged in thesupport flange 81 and which receives ahinge axis 85 of thebulwark 3 around which the latter can pivot. - In other words, the
first positioning device 20 and thesecond positioning device 50 are configured to position thesupport flange 81 and hence thehinge axis 85 of thebulwark 3. -
FIGS. 22 to 24 show an example of adjustment of thishinge axis 85 via themechanism 5 and along the first and second adjustment directions. - The adjustment is performed preferably in the closed position of the
bulwark 3, to place it perfectly flush with thehull 2. -
FIG. 22 shows themechanism 5 in a so-called “neutral dead center” position, where the first adjustment direction D1 and the second adjustment direction D2, an adjustment zone which corresponds here to the area of the second off-centeredorifice 66 of the second notchedwheel 65 of thesecond positioning device 50, and also adjustment marks R1, R2 and R3 respectively formed on thebase 6, thefirst positioning device 20 and thesecond positioning device 50, with these marks R1-R3 which are aligned, are represented. The point P1 represents the nominal position of the second off-centeredhole 52 of thesecond positioning device 50. - Relative to a desired position of the
hinge axis 85 of thebulwark 3, in accordance with a predetermined scale, the first notchedwheel 40 and/or the second notchedwheel 65 must be rotated relative to the so-called “neutral dead center” position, using thefirst operating key 46 and/or thesecond operating key 69, respectively. - The rotation of the first notched
wheel 40 and/or the second notchedwheel 65 may have to be performed in the clockwise or anticlockwise direction. - In
FIG. 23 , the first notchedwheel 40 and the second notchedwheel 65 are rotated in the anticlockwise direction along a first determined angle α1. The marks R2 and R3 are moved whereas the mark R1 does not move. - In
FIG. 24 , only the second notchedwheel 65 is rotated in the anticlockwise direction along a second determined angle α2. Only the mark R3 is therefore moved. - The rotation of the first notched
wheel 40 and the second notchedwheel 65 along the first determined angle α1 in the anticlockwise direction, followed by the rotation of only the second notchedwheel 65 along the second determined angle α2 in the clockwise direction, makes it possible to offset the second off-centeredhole 52 of thesecond positioning device 50 from the nominal position thereof to the desired position P2 of the hinge axis of the bulwark. - Obviously, according to the desired position P2, the values of the angles of rotation and/or the direction of rotation and/or the notched wheel to be rotated can change.

mechanism 5 is in the desired position P2, themechanism 5 is locked in position first by clamping the clampingcollar 29 around the clampingjaws 28 to lock thesecond body 52 of thesecond positioning device 50 in position, then the lockingmember 15 is actuated against the curvedelastic member 13 of themain body 8 of thebase 6, which is deformed and which locks thefirst body 21 of thefirst positioning device 20 in position. - In the
mechanism 5 described, thefirst positioning device 20 and thesecond positioning device 50 are each of the so-called eccentric type. - The
mechanism 5 thus offers the option of adjusting along two separate directions thebulwark 3 in position relative to thehull 2 and more generally a movable part relative to a support, so as to make it possible, in the retracted configuration, to place the movable part flush with the support and, in the deployed configuration, to place the movable part at a distance from the support. - The
mechanism 5 has the advantage of enabling an easier adjustment by merely actuating the first notchedwheel 40 and/or the second notchedwheel 65, so as to position thefirst positioning device 20 and along the second direction via thesecond positioning device 50. - Alternatives that are not illustrated are described hereinafter.
- The thicknesses of the main body and the sole plate are identical or conversely the sole plate is thicker.
- The base is formed from one piece rather than with a separate sole plate and main body.
- The main body has an annular shape.
- The first positioning device can include more or less recesses in the first body thereof and associated jaws.
- The different elements of the mechanism include more or less assembly, centering and/or fastening orifices.
- The different elements of the mechanism can be made of metal or plastic or of composite material.
- More generally, the invention is not limited to the examples described and shown.
