Description

PORT INSTALLATION FOR THE PARKING OF SHIPS IN THE HARBOR. Technical area

The present invention is in the field of port equipment used for the parking of pleasure craft at the port and relates to a port facility capable of increasing the capacity of a marina.

State of the prior art.

The port infrastructure dedicated to the yardage of ships at the port typically includes a dock or pontoon, from which parallel catways radiate defining parking spaces for pleasure craft. These catways are fixed or floating secondary pontoons developing transversely to the main dock or pontoon.

They are usually equipped with means of mooring the boat, such as rings and others.

We know that many marinas have reached saturation and the only possibility they have to increase their capacity is to increase their influence on the maritime domain. However, this solution, onerous in itself, can only be adopted if the regulations in force allow it.

Presentation of the invention. The present invention relates to a port facility to increase the capacity of home without increasing the influence on the maritime domain.

For this purpose the port facility according to the invention, aimed at increasing the capacity of a marina, provided to be secured to a dock or pontoon 1 of the port, is essentially characterized in that it comprises an elevating structure delimiting a first parking space afloat for a first vessel and a nacelle carried by this lifting structure, designed to receive a second vessel to be parked, at least said nacelle being movable between an immersed extreme low position according to which it is located adjacent to the first parking location and an extreme high position emerged, the movement of the nacelle from one to the other position being a translational movement.

This provision is conducive to doubling the parking capacity of a port without increasing the influence on the maritime domain.

The translational movement communicated to the nacelle eliminates any risk of pivoting the latter forward or backward so that the vessel in this nacelle occupies a stable position. According to an additional feature, the nacelle in the low submerged position is located adjacent to the location dedicated to the first vessel and in the high position, above this location.

Because of this arrangement, it maximizes the parking capacity without hindering navigation in the port. According to another characteristic of the invention, the lifting structure comprises a securing means at the dock or pontoon delimiting the location dedicated to the parking of the first ship, two deformable parallelogram parallel, parallel, spaced from each other and developing each in a lateral vertical plane at the dedicated location, each deformable parallelogram comprising a front upright, a rear upright both hinged by means of attachment and an upper beam, horizontal, hingedly supported by the two uprights, the nacelle being fixed the two longitudinal members, the two deformable parallelograms being moved synchronously between the two extreme positions of the nacelle by a motor means. According to another characteristic of the invention, the securing means comprises two parallel, horizontally spaced, parallel horizontal pontoons, intended to be secured to the dock or pontoon and delimiting the space dedicated to the first ship, the two deformable parallelograms of the lifting structure being secured to one of one of the secondary pontoons and the other of the other secondary pontoon.

According to another characteristic of the invention, the drive means comprises two driving half-shafts coupled to the same drive member fixed to the dock or pontoon, and two transmissions multiplying rotational movement ensuring for one the transmission of the movement of rotation between one of the half drive shafts and the rear post of one of the deformable parallelograms 35 and for the other the movement transmission between the other driving half-shaft 50 and the rear post of the other deformable parallelogram. According to another characteristic of the invention, the driving means comprises a drive shaft coupled to the same drive member fixed to the dock or pontoon, the driving member is constituted by a hydraulic jack hinged by its body to a fixed integral fitting of the dock or pontoon and its rod, always articulated to a clevis carried by a transmission lever radially fixed to the transmission shaft and the drive shaft is coupled to two transmissions multiplying rotational movement ensuring the transmission of the rotational movement between this drive shaft and the rear post of each deformable parallelogram. According to another characteristic of the invention, each transmission of movement consists of a toothed pinion fixed in rotation and translation on the shaft or the corresponding half-shaft, of a toothed wheel of larger diameter than that of the pinion, fixed in translation and rotation on the corresponding rear upright, said wheel being centered on the pivot axis of the rear upright and an articulated link chain, meshing with the pinion and the wheel.

According to another characteristic of the invention, the lifting structure is provided with at least one float.

According to another characteristic of the invention, the float is arranged in ballast and forms the driving means for actuating the lifting structure between its two extreme low and high positions. Brief description of figures and drawings.

Best ways to achieve the invention As shown in the attached figures, the port facility aims to increase the capacity of a marina and is intended to be secured to a dock or pontoon 1 of the port.

This installation comprises a lifting structure 3 secured to the dock or pontoon 1 delimiting a first dedicated location 2 for the afloat of a first vessel, this location facing the dock or pontoon 1 and extending perpendicular or parallel and more generally adjoining the latter.

The installation further comprises a nacelle 4 carried by the lifting structure 3 and provided to receive a second vessel to be parked, at least said nacelle 4 being movable between an immersed extreme low position in which it is located adjacent to the location dedicated in this case back, and an extreme high position emerged, the movement of the nacelle 4 from one to the other position being a translational movement, preferably a translational movement circular. In the extreme low position, the nacelle 4 can receive a ship, its depth of immersion being greater than the draft of this ship. In the extreme high position, the nacelle 4 is arranged at a height such that the first ship can leave or reach the dedicated location 2 without the risk of colliding. According to the preferred embodiment, the lifting structure 3 is deformable and the nacelle in the extreme upper position is located above the slot 2.

This lifting structure 3 comprises a securing means at the dock or pontoon 1 delimiting the location 2 dedicated to the parking of the first ship, two parallel deformable parallelograms 35, supported by the securing means 30, these two deformable parallelograms being moved between the two positions extremes of the nacelle 4 by the same motor means 5.

As can be seen, these deformable parallelograms 35 are parallel, spaced from each other and each develop in a lateral vertical plane at the parking location 2 of the first ship.

According to the preferred embodiment, the securing means 30 comprises two parallel or fixed horizontal parallel or secondary catways, fixed or floating, secured to the dock or to the main pontoon 1 spaced apart from each other, and delimiting the location 2 the two deformable parallelograms 35 of the lifting structure 3 being integral with one of the catways and the other with the other catway.

Each catway 30 may be fixedly installed on vertical piles 11 anchored to the ground or may be slidably mounted on these piles to follow the movement of waves and tide. These catways will be equipped with mooring means for ships such as rings and others and ad hoc floats.

The two catways or secondary pontoons 30 are joined rigidly to one another by U-shaped bows 31. This arrangement is intended to prevent any relative movement of the two catways relative to each other and has the effect of effect of forming a solid and indeformable base on which support the two parallelograms of the deformable structure.

Each deformable parallelogram 35 comprises a front upright 351, a rear upright 352 both articulated to the attachment means 30 namely the corresponding catway and an upper spar 353, preferably horizontal, hingedly supported by the two uprights 351, 352. At both 353 members of the deformable structure is fixed to the nacelle 4. Note in the accompanying figures that the front post 351 is bent at the upper end to form, in the extreme position of the nacelle, a cantilever above the dock or main pontoon 1 In this position, apart from its upper end, the upright 351 develops substantially vertically and bears against the main dock or pontoon 1.

Preferably, the nacelle 4 forms a cradle housing constituting the second vessel, this cradle being formed by two U-shaped arches spaced apart from each other and rigidly fixed each by their lateral branches to the two longitudinal members 353 of the deformable structure. These two U-shaped arches each extend in a vertical plane and downwards with respect to the spars 353. may be braced in any known manner. These two arches 40 can support a protective cover 41 (Fig.5), forming a sealed bottom adapted to retain particular flows of water and other from the second vessel. Thus in the extreme high position, the first ship will be protected from these flows. Advantageously, this protective cover 41 may be provided with a vertical front flank, two vertical lateral flanks and a downwardly inclined rear flank forming a flow spout. Due to this arrangement, these possible flows may be rejected behind the location 2. The nacelle is provided with a front stop 42 in the form of horizontal bent arm, rigidly attached to the two longitudinal members 353 of the deformable structure 3. This provision in particular for the purpose of avoiding that the second ship does not hit the first during the maneuver installation on the platform. The arches 40 and the front stop 42 form a rigid structure which binds in the upper part, the two parallelograms to each other and opposes the kinking of the elevating structure 3.

According to a preferred embodiment, the drive means 5 comprises two driving half-shafts 50 coupled to the same drive member 51 intended to be fixed to the dock or to the pontoon 1, and two transmissions multiplying rotational movement ensuring for the a transmission of the rotational movement between one of the half-shafts of wheels 50 and the rear post of one of the deformable parallelograms and for the other, the transmission of movement between the other half-wheel shaft and the rear pillar of the other deformable parallelogram. The motor member 51 may be arranged in a waterproof box adapted to be fixed in any known manner to the dock or the pontoon 1. This motor unit will incorporate a gear motor of the irreversible type.

Each drive half-shaft 50 remote from the drive member 51 can be engaged in a sliding bearing that can be formed in the corresponding catway 30 or in a bearing body intended to be fixed to the dock or pontoon 1. In In the first case, the front post of the corresponding parallelogram 351 may be articulated to this drive half-shaft 50. Each transmission of multiplier movement may be consisting of a toothed pinion 52 fixed in rotation and translation on the corresponding half-shaft 50, of a toothed wheel 53 of larger diameter than that of the pinion 52, fixed in translation and rotation on the corresponding rear post 352, said wheel 53 being centered on the pivot axis of the rear pillar, and a chain 54 with articulated links, meshing with the pinion 52 and the wheel 53. As known to this transmission will be associated with at least one chain tensioner not shown.

It should be noted that the reasons for the two transmissions of movement of the lifting structure 3 will be identical and that the drive half-shafts 50 of the motor means 5 will rotate at the same angular velocity. Due to these arrangements, the two deformable parallelograms 35 will be driven by the motor means 5 in a perfectly synchronous manner, which eliminates the risk of parasitic mechanical stresses in the elements making up the nacelle. According to another embodiment, as represented in FIG. 4, the motor means 5, in place of the two drive half-shafts, comprises only one drive shaft 50 coupled to the two pinions 52 and motor member 51 is constituted by a hydraulic or pneumatic cylinder hinged by its body to a fixed fitting of the dock or pontoon 1 By its rod, this jack is hingedly attached to a clevis carried by a transmission lever 55 fixed radially to the drive shaft 50. Deployment and retraction of the cylinder rod, relative to the cylinder body, cause the rotation of the drive shaft 50 in one direction or the other. According to another embodiment, the driving means 5 is constituted by two hydraulic or pneumatic cylinders 56 (FIG. 5) connected to a common hydraulic or pneumatic circuit, one of the jacks being articulated to one of the catways 30 and rear upright 352 and the other cylinder 56 being hinged to the other catway 30 and the other rear upright 352. It goes without saying that the hydraulic or pneumatic circuit will be provided with means known per se capable of ensuring synchronous operation two cylinders.

Advantageously, the hydraulic fluid used will be water or air. In this way, a leak in the hydraulic circuit will not cause any pollution. Note in the accompanying figures that each deformable parallelogram 35, and more precisely the corresponding quadrilateral whose four vertices correspond to the joints of the two uprights 351 and 352 to the catway 30 and the spar 353 is, in the extreme high position of the nacelle, deformed towards forward. In this position, the front post of each parallelogram comes to bear against a stop 10 which may be constituted by the platform 1 itself or by a specific abutment means intended to be fixed to the dock or pontoon. From the foregoing, it follows that the lifting structure 3, in the extreme high position of the nacelle 4, under the effect of its own weight, that of the nacelle and the vessel possibly carried by the latter, comes from itself. even in abutment against the abutment 10 mentioned above.

Although the extreme high position is a stable equilibrium position, it is advantageous to enhance security, to add to the lifting structure a locking means, not shown, prohibiting when active maneuver thereof. By way of example, this locking means may be constituted by an articulated arm having a hook shape adapted, by pivoting the arm, to engage around the front post 351 or in a hook shape that may present. latest.

To this locking means may be added an electrical contactor prohibiting the power supply of the motor as long as the locking means is active.

Advantageously, to reinforce the stability of the structure in extreme high position, the spar 353 of each deformable parallelogram carries a vertical strut supported by its lower end on the corresponding secondary pontoon, in the extreme high position of the nacelle. This leg will be equipped with a ladder so that the user can access the second ship.

According to another embodiment of the invention, the lifting structure 3 is provided with at least one float 354, so as to follow the movement of the waves and the tide. Preferably, the lifting structure will be provided with two floats carried respectively by the two longitudinal members 353 and occupying a fixed position relative to the latter. These two floats 354 are also intended to facilitate the lifting maneuver of the nacelle. Each float 354 is arranged in watertight case, of parallelepipedal shape having a longitudinal axis extending vertically. In the upper part, each watertight box has rigid attachment means to the corresponding spar.

The lifting structure 3 may be provided with floats 354 and strut, but preferably, the two floats will constitute the legs of force mentioned above.

Figures 6 to 8 show another embodiment of the invention in the various stages of elevation of the lifting structure 3. To this lifting structure are always associated two lateral floats 355. Each of these floats 355 has an arm 356 , extending forwards, by which it is articulated to the corresponding catway 30. Furthermore, the float 355 receives in articulation a link 357 articulated to the corresponding amount 352. Finally, each deformable parallelogram 35 may be associated with a gas spring 358, mechanically interposed between one of the uprights 351, 352 and the adjacent secondary pontoon 30. Such gas springs 358 are visible in Figures 7 and 8. It can be seen that each of these is articulated on the one hand to the amount 352 and the other side pontoon 30 adjacent. These gas springs are in complete compression in the extreme high position of the lifting structure 3 and relaxing are intended to facilitate the beginning of the movement of this lifting structure 3 from the high position to the low position. Each float 355 will have a stepped shape for access to the second vessel in the upper position of the nacelle.

Preferably, the floats 355 are arranged in ballast and each have an air inlet coupled to a source of compressed air via a pipe comprising a control valve, and secondly a water inlet associated with a pipe and to a second control valve. Each float 355 will further comprise, in the upper part, an air outlet and in the lower part a water outlet each associated with a control valve.

This ballast arrangement has the advantage of constituting a variant of the motor means 5 for actuating the lifting structure 3 between the two extreme positions.

For the actuation of the elevating structure 3 from the submerged position to its high position, compressed air will be introduced into each float and under the effect of the air pressure, the water contained in the latter will be expelled by passage through the dedicated evacuation. The lifting structure 3 can then reach its extreme high position. It should be noted that in this position, each float is partially submerged. To move the elevating structure 3 from its upper position to its lower position, water will be introduced into the floats in order to weigh down the latter. The air contained in these will be hunted by passage through the dedicated evacuation.

Such a ballast arrangement to be adopted for the floats 354. In this case, these floats and ballast arrangements will constitute the driving means 5.

Alternatively, the installation may be provided with first motor means 5 comprising chain and pinion transmissions and / or cylinders and second motor means constituted by floats arranged in ballast. At each secondary pontoon 30 may be added at least one ballast 36 with neutral buoyancy constituted, for example, by a watertight box filled in part by a heavy weight. This ballast will be fixed to the secondary pontoon in its front part (part near the dock) and will have the effect of constituting a counterweight capable of opposing the depression of the rear part of the catway 30 in particular during the movement of the lifting structure 3 and the ship she is carrying.

Advantageously, the heavy mass will consist of a suitable quantity of water. Such ballast 36 is shown in FIG.

Additionally, the ballast 36 may be movably mounted along the catway 30 which receives it. It goes without saying that the present invention is not limited to the embodiments described above but on the contrary it encompasses the embodiments.
