The present invention is in the field of launching devices for maritime boats, and relates in particular to the launching of pleasure boats and sport sailing. More particularly, the invention relates to the launching of light nautical boats such as dinghies or small catamarans.

For the launching and transporting of watercraft such as dinghies, it is generally resorted to the use of trolleys which are used for transport on the road and / or launching on a beach or hold grounding. This type of device is heavy and bulky, and requires having to store the equipment on the ground during a trip on the water.

For the transport and launching of inflatable boats, supports comprising a tubular axis mounted on a wheel are known, such as for example the system described in application FR 2 543 102. Such a system is complicated to mount on the hull of the boat and requires fixing elements there by drilling which remain in place during navigation, thus disturbing both the aerodynamic and hydrodynamic properties, and requiring irreversible modification of the ship.

Application FR 2 740 101 describes a device for launching small boats integrating fasteners and points of support on the beam, and external and internal parts of the hull. Such a device is complex due to its morphology, it requires attachment points (hooks, ...) and the presence of tensioners is required to connect each side of the hull of the boat. This device is also complex due to its operation, a guide fork is necessary for ground maneuvers.

The present invention aims to solve the problems of the prior art and for this purpose relates to a launching device for a watercraft, intended to be fixed to the hull of such a watercraft and comprising a tubular body which extends between a first end and a second end, at least one running gear connected on the first end of the tubular body, a support bar which extends laterally on the second end of the tubular body and an adhesion fixing means removable.

The term "removable" means that the device can be mounted and dismounted on the shell without damaging, altering or modifying the surface on which adhesion occurs. For metal shells, it can be used using at least one fixing magnet.

Such a device is particularly advantageous because the practitioner is not required to abandon the equipment during navigation, the device being able to be easily embarked on the nautical boat: which also makes it possible to take the boat out of the outside the launching area. Such a device is particularly light and compact, and it avoids unwanted impacts on the hull.

The running gear comprises at least one wheel and a wheel axle on which the wheel is fixed. The wheel axle is fixedly mounted directly or indirectly on the first end of the tubular body. Advantageously, the wheel axle is not fixed in a non-removable manner (for example by welding) on the tubular body, but it comprises a key designed to hold it in place. Being able to fix the wheel axle by keying makes it possible to position the wheel on either side of the tubular body for a better distribution of forces.

Preferably, the running gear comprises a single wheel and its wheel axle mounted directly on the first end of the tubular body. Such a device with a single wheel is compact, that is to say it is compact and light, which is particularly suitable for the intended use. Alternatively, the running gear can comprise at least two wheels advantageously disposed on each side of the tubular body to compensate for irregularities in the ground, in particular when the device is used on soft ground, as is most often the case with beaches. that line the coast.

The removable adhesion fixing means advantageously comprises at least one suction cup capable of being fixed to a side of the hull of a nautical craft. The suction cups used are preferably lever suction cups, such suction cups are used in the field of bodywork and are described in application FR 2 758 786. Such lever suction cups are easy to position, to actuate, and are compatible with immersion in water. In addition, the inventors have found better adhesion during immersion in the aquatic environment. Such a device is particularly suitable for hulls with long chines, that is to say hulls with sharp angles and flat parts. In contrast to shaped hulls which have a curved shape, keel chines hulls, which were widely used from the nineteen hundred and fifty years for dinghies notably in plywood and / or sheet metal, are now very popular for many shipbuildings in composite materials. However, the present invention is also suitable for shaped hulls with suction cups configured accordingly, for example with a curved shape.

Advantageously, the removable adhesion fixing means comprises two suction cups positioned substantially on either side of the tubular body. This positioning allows the user to easily place the suction cups and provide a secure support surface to avoid inadvertent movements during movement of the boat before or after launching.

Advantageously, said one or more suction cups are pivotally mounted on the tubular body. In this context, according to one embodiment, the suction cups are mounted on an axis of rotation integral with the tubular body of the device. According to a preferred embodiment, the suction cups can pivot 180 ° on their axis, which makes it possible to adapt the device to all the inclinations of the boat hulls.

The support bar advantageously has a circular section. Such a configuration of the support bar facilitates the abutment against the edge of a hull, and in particular against the strake for watercraft equipped with such a strake, as is the case for certain small dinghies.

The support bar advantageously consists of a tube made of stainless steel and / or galvanized, and preferably of anodized aluminum, covered at least in part, with a protective foam. Such a tube resists the mechanical stresses applied during the transport of a boat, and resists physical and chemical attack caused by the marine environment. The protective foam prevents damage to the shell during transport and provides a non-slip function. Advantageously, all of the elements of the chassis of the device according to the invention, such as the tubular body, and the elements for holding the suction cups and the wheels, are made of anodized aluminum and / or include anodized aluminum.

The device advantageously comprises a T-shaped tubular extension, qualified and T-shaped, composed of a main rod and two arms which stretch laterally to form the branches of the T, the main rod is inserted into the tubular body, and each branch of the T extends in the direction of the above suction cups. The position of the main rod is advantageously adjustable in the tubular body, the main rod advantageously comprises for this purpose a set of holes which pass right through it and which are provided for positioning a pin which also passes through the tubular body at the level of the junction between said main rod and said tubular body. It then becomes possible to adjust the distance of the suction cups from the tubular body. The tubular body advantageously comprises a set of orifices which pass right through it, and which are provided at regular intervals, in order to be able to adjust the height of the fastening means by adhesion in the configuration of use.

The two arms of the T advantageously form a gutter, such a gutter is suitable for encapsulating the handles of bodywork suction cups by blocking the sliding of the handle in the T. Each suction cup is held on a plate, and the ends of the gutter come in abutment on these plates for a firm hold of the suction cup system integrated in the device. The main advantage of this type of configuration is that the untimely movements of the suction cups relative to the rest of the device according to the invention are prevented for better stability during transport and launching.

The device advantageously comprises a wedging means adapted to be positioned in abutment under the hull of a ship.

The present invention also relates to an assembly comprising at least two launching devices according to the invention as presented previously intended to be positioned on either side on the sides of the hull of a watercraft.
