The object of the present invention relates to the field of devices for handling and moving a cargo comprising at least one heavy and / or bulky object.
L’objet de la présente invention porte plus particulièrement sur une remorque destinée à la manutention et au déplacement d’une cargaison en zone carrossable et/ou en zone non carrossable. The object of the present invention relates more particularly to a trailer intended for handling and moving cargo in a drivable area and / or in a non-drivable area.
La présente invention trouvera de nombreuses applications avantageuses dans différents domaines dont notamment la manutention et le déplacement à terre d’un engin nautique tel que par exemple une embarcation légère, la présente invention étant particulièrement adaptée aux opérations de mise à l’eau et de remontée d’une telle embarcation légère.

Art antérieur Prior art
L’accès au rivage pour arriver sur la zone d’embarcation peut être difficile et nécessite parfois de traverser une zone non carrossable telle que par exemple une zone marécageuse, sableuse ou une prairie. Ceci peut également être le cas lorsque la zone d’embarcation nécessite de traverser une plage de sable, par exemple à marée basse, ou une zone de sol meuble, souvent inaccessible avec une remorque classique. Access to the shore to get to the boat area can be difficult and sometimes requires crossing a non-drivable area such as for example a swampy, sandy area or a meadow. This can also be the case when the boat area requires crossing a sandy beach, for example at low tide, or an area of loose soil, often inaccessible with a conventional trailer.
On connaît dans le domaine des remorques pour embarcation légère le document FR3029147A1. La remorque proposée dans ce document est adaptée pour le déplacement sur terre et la mise à l'eau d'une telle embarcation légère. Document FR3029147A1 is known in the field of light craft trailers. The trailer proposed in this document is suitable for moving on land and launching such a light boat.
Il est prévu dans ce document une remorque présentant un train roulant porteur motorisé qui est configuré pour supporter la coque de l’embarcation et qui comporte un moteur électrique étanche, en particulier un groupe motoréducteur, permettant la motorisation de deux ensembles de roues, chaque ensemble de roues comportant au moins deux roues de nature différente adaptée chacune pour un type de sol en particulier. There is provided in this document a trailer having a powered undercarriage which is configured to support the hull of the boat and which comprises a sealed electric motor, in particular a geared motor unit, allowing the motorization of two sets of wheels, each set wheels comprising at least two wheels of different types, each adapted for a particular type of soil.
Dans ce document, on prévoit un système de roues débrayables de manière à pouvoir s’adapter à l’environnement. In this document, a system of disengageable wheels is provided so as to be able to adapt to the environment.
L’opérateur peut alors commander la remorque pour les opérations de mise à l’eau et de remontée de l’embarcation par l’intermédiaire d’un boîtier de commande situé à l’avant de la remorque au niveau du timon. The operator can then control the trailer for launching and raising the boat through a control box located at the front of the trailer at the drawbar.
Une telle remorque est appréciée des utilisateurs. Such a trailer is popular with users.
Celle-ci permet notamment à l’utilisateur d’amener son embarcation dans une zone d’embarcation lorsque cette dite zone est séparée de la route (zone carrossable) par une zone non carrossable. This allows the user in particular to bring his boat into a boat area when this said area is separated from the road (drivable area) by a non-drivable area.
Le Demandeur soumet néanmoins que la remorque telle que proposée dans le document FR3029147A1 n’est pas pleinement adaptée pour la mise à l’eau, pour l’immersion prolongée ni pour les situations d’enlisement. The Applicant nevertheless submits that the trailer as proposed in document FR3029147A1 is not fully suitable for launching, for prolonged immersion or for sinking situations.
Le Demandeur soulève en outre que la remorque telle que proposée dans le document FR3029147A1, ne permet pas de d’être tractée dans des conditions normales de circulation, notamment sur autoroute (limitation à 30km/h). The Applicant further points out that the trailer as proposed in document FR3029147A1 does not allow it to be towed under normal traffic conditions, in particular on the motorway (limitation to 30 km / h).
Le Demandeur soulève également que la remorque telle que proposée dans le document FR3029147A1 ne prévoit pas la mise en œuvre de solution pour assurer l’étanchéité des roues afin de protéger le système de freinage de la corrosion. The Applicant also points out that the trailer as proposed in document FR3029147A1 does not provide for the implementation of a solution to ensure the sealing of the wheels in order to protect the braking system from corrosion.
Le Demandeur soulève en outre que la remorque telle que proposée dans le document FR3029147A1 ne prévoit pas la mise en œuvre d’une solution pour assurer la sécurité de l’embarcation contre les vols, notamment en cas de stationnement prolongé. The Applicant further points out that the trailer as proposed in document FR3029147A1 does not provide for the implementation of a solution to ensure the safety of the boat against theft, in particular in the event of prolonged parking.
On connaît également dans l’art antérieur d’autres solutions telles que par exemple celles proposées dans les documents EP1561637A1, EP2402210A2, US6079729 A ou encore le document GB2419853A. Other solutions are also known in the prior art, such as, for example, those proposed in documents EP1561637A1, EP2402210A2, US6079729 A or even document GB2419853A.
Le demandeur soumet que les solutions proposées dans ces documents et destinées à la mise à l’eau d’embarcation sont intéressantes, mais qu’aucune d’entre elles ne permet un déplacement du véhicule sur la route. Il s’agit d’engins à part entière qui sont spécialement dédiés à la mise à l’eau. The applicant submits that the solutions proposed in these documents and intended for the launching of a boat are interesting, but that none of them allows a displacement of the vehicle on the road. These are full-fledged gear that are specially dedicated to launching.
On connaît enfin le document US2007272452A1. Finally, the document US2007272452A1 is known.
Dans ce document, il s’agit d’une remorque hybride comprenant un système de chenilles motorisées monté sur des vérins et dont le réglage en hauteur permet de traverser certaines zones non carrossables. En revanche, le système de chenilles est positionné en portion centrale du châssis au niveau des roues, ce qui nécessite une surélévation du châssis pour mettre en contact les chenilles avec le sol et neutraliser les roues. Cette conception n’apporte pas de réponse satisfaisante concernant le franchissement d’un obstacle sans un risque de basculement brutal de la charge. In this document, it is about a hybrid trailer comprising a motorized track system mounted on jacks and whose height adjustment makes it possible to cross certain non-drivable areas. On the other hand, the track system is positioned in the central portion of the frame at the level of the wheels, which requires an elevation of the frame to bring the tracks into contact with the ground and neutralize the wheels. This design does not provide a satisfactory answer concerning the crossing of an obstacle without a risk of sudden tipping of the load.
Le Demandeur observe de plus qu’il n’est nulle part fait mention dans ce document de la problématique de protection des organes de freinage, ou encore la problématique du vol de remorque. The Applicant further observes that there is no mention anywhere in this document of the problem of protecting the braking members, or even the problem of trailer theft.
Ainsi, les techniques divulguées dans les différents documents de l’art antérieur permettent soit de faciliter la mise à l’eau soit de traverser des zones non-carrossables. Thus, the techniques disclosed in the various documents of the prior art make it possible either to facilitate entry into the water or to cross non-drivable areas.
Le Demandeur cherche ici à améliorer les différentes solutions techniques proposées jusqu’à présent dans les documents mentionnés ci-dessus. The Applicant here seeks to improve the various technical solutions proposed so far in the documents mentioned above.
Le problème général auquel prétend répondre la présente invention est donc celui de favoriser le déplacement d’au moins un objet lourd et/ou encombrant tel que par exemple une embarcation légère en zone carrossable et/ou en zone non carrossable. The general problem to which the present invention claims to respond is therefore that of promoting the movement of at least one heavy and / or bulky object such as for example a light craft in a drivable area and / or in a non-drivable area.
L’un des problèmes techniques résolus dans le cadre de la présente invention sera également de favoriser les opérations de mise à l’eau et de remontée d’une embarcation légère. One of the technical problems solved in the context of the present invention will also be to promote the launching and lifting operations of a light craft.
Le Demandeur cherche en outre à concevoir une remorque hybride motorisée qui est conçue pour être mise à l’eau en limitant les risques de corrosion, notamment au niveau du système de freinage. The Applicant further seeks to design a motorized hybrid trailer which is designed to be launched while limiting the risks of corrosion, in particular in the braking system.
Le Demandeur prétend qu’à ce jour aucune des solutions de l’art antérieur ne permet de répondre de façon satisfaisante à ces différents problèmes. The Applicant claims that to date none of the solutions of the prior art have made it possible to respond satisfactorily to these various problems.
Objet et résumé de la présente invention Object and summary of the present invention
Un des objectifs de la présente invention vise donc à améliorer la situation décrite ci-dessus en proposant la conception d’une remorque qui répond au moins partiellement aux différents problèmes ci-dessus. One of the objectives of the present invention is therefore to improve the situation described above by proposing the design of a trailer which at least partially responds to the various problems above.
La présente invention vise plus particulièrement à remédier à au moins un des différents problèmes techniques mentionnés ci-dessus en proposant selon un premier aspect une remorque hybride pour un déplacement d’une cargaison en zone carrossable et/ou en zone non carrossable. The present invention aims more particularly to remedy at least one of the various technical problems mentioned above by proposing according to a first aspect a trailer. hybrid for moving cargo in a drivable area and / or in a non-drivable area.
Avantageusement, la remorque selon la présente invention comprend une structure porteuse servant de châssis. Advantageously, the trailer according to the present invention comprises a supporting structure serving as a frame.
On comprendra ici qu’une telle structure est configurée pour supporter ladite cargaison. It will be understood here that such a structure is configured to support said cargo.
Dans une application avantageuse de la présente invention dans laquelle ladite cargaison est une embarcation, on comprendra que la structure porteuse est configurée pour supporter et recevoir au moins une portion de la coque de l’embarcation. In an advantageous application of the present invention in which said cargo is a boat, it will be understood that the supporting structure is configured to support and receive at least a portion of the hull of the boat.
Dans ce cas, on peut prévoir par exemple que la structure porteuse comporte des moyens pour recevoir, tenir et/ou stabiliser la coque tels que par exemple des sangles, des rouleaux, des patins, un support en V, à angle d'ouverture réglable ou autres. In this case, provision can be made, for example, for the supporting structure to include means for receiving, holding and / or stabilizing the shell, such as for example straps, rollers, pads, a V-shaped support, with an adjustable opening angle. or others.
Avantageusement, sont montés sur ladite structure porteuse un essieu arrière (par exemple, deux demi-essieux) comprenant au moins une paire de roues arrière escamotable, et un système de chenilles motorisées rétractable disposé à l’arrière du châssis. Advantageously, are mounted on said supporting structure a rear axle (for example, two half-axles) comprising at least one pair of retractable rear wheels, and a retractable motorized track system arranged at the rear of the chassis.
Avantageusement, la remorque selon la présente invention comporte en outre des moyens de commande qui sont configurés pour commander l’essieu arrière et le système de chenilles de manière à autoriser le passage d’une première configuration, dite de route, vers une deuxième configuration, dite autonome, ou inversement. Advantageously, the trailer according to the present invention further comprises control means which are configured to control the rear axle and the crawler system so as to allow the passage from a first configuration, called road, to a second configuration, called autonomous, or vice versa.
Selon la présente invention, les moyens de commande permettent de placer la remorque dans une configuration de route dans laquelle les roues arrière sont en contact avec le sol et le système de chenilles est rétracté pour un déplacement de ladite remorque en zone carrossable par un véhicule tracteur. According to the present invention, the control means make it possible to place the trailer in a road configuration in which the rear wheels are in contact with the ground and the track system is retracted for a movement of said trailer in a drivable zone by a towing vehicle. .
Selon la présente invention, les moyens de commande permettent de placer la remorque dans une configuration autonome dans laquelle le système de chenilles est en contact avec le sol et les roues arrière sont escamotées pour un déplacement autonome en zone non carrossable par le système de chenilles. According to the present invention, the control means make it possible to place the trailer in an autonomous configuration in which the track system is in contact with the ground and the rear wheels are retracted for autonomous movement in a zone which cannot be driven by the track system.
Grâce à cette combinaison de moyens techniques, caractéristique de la présente invention, et notamment grâce à la conception de cette remorque hybride comprenant des roues arrière escamotables et un système de chenilles rétractable, l’utilisateur d’une telle remorque peut déplacer sa cargaison et notamment son embarcation dans une zone carrossable en activant les roues arrière en configuration de route pour tracter via l’attelage ladite remorque grâce à un véhicule tracteur, et ensuite, en configuration autonome, commander le déplacement de la remorque dans une zone non carrossable en activant le système de chenilles motorisé. Thanks to this combination of technical means, characteristic of the present invention, and in particular thanks to the design of this hybrid trailer comprising retractable rear wheels and a retractable track system, the user of such a trailer can move his cargo and in particular his boat in a drivable area by activating the rear wheels in road configuration to tow said trailer via the coupling using a towing vehicle, and then, in autonomous configuration, control the movement of the trailer in a non-drivable area by activating the motorized track system.
Un seul engin est donc ici nécessaire. Le Demandeur observe que, dans le document US2007272452A1, les roues ne sont pas escamotables, ce qui nécessite d’avoir un système de chenilles dont l’actionnement nécessite une élévation importante du châssis pour les déplacements en zone non carrossable. Une telle conception rend peu stable la remorque dans ce genre de situation. Only one machine is therefore necessary here. The Applicant observes that, in document US2007272452A1, the wheels are not retractable, which necessitates having a track system, the actuation of which requires a significant elevation of the chassis for movements in a non-drivable zone. Such a design makes the trailer unstable in this type of situation.
Selon différents modes de réalisation pouvant être combinées les unes aux autres la remorque selon l'invention présente également diverses caractéristiques complémentaires. According to different embodiments which can be combined with one another, the trailer according to the invention also has various complementary characteristics.
Dans un mode de réalisation particulier de la présente invention, un essieu avant est monté sur la structure porteuse, un tel essieu avant comprenant au moins une paire de roues avant rétractables. In a particular embodiment of the present invention, a front axle is mounted on the supporting structure, such a front axle comprising at least one pair of retractable front wheels.
Dans ce mode, on prévoit de préférence que les moyens de commande sont configurés pour commander l’essieu avant de manière à ce que les roues avant sont en contact avec le sol en configuration de route et en configuration autonome. In this mode, provision is preferably made for the control means to be configured to control the front axle so that the front wheels are in contact with the ground in road configuration and in autonomous configuration.
De préférence, les roues avant sont directionnelles. Preferably, the front wheels are directional.
Dans un mode de réalisation avantageux de la présente invention, on prévoit que les moyens de commande sont configurés pour positionner ladite remorque dans une configuration de stationnement dans laquelle les roues avant et le système de chenilles sont rétractés et les roues arrière sont escamotées de manière à ce que ladite structure porteuse est en contact direct avec le sol pour empêcher le déplacement de ladite remorque. In an advantageous embodiment of the present invention, provision is made for the control means to be configured to position said trailer in a parking configuration in which the front wheels and the track system are retracted and the rear wheels are retracted so as to that said supporting structure is in direct contact with the ground to prevent the movement of said trailer.
Une telle configuration permet de limiter de façon significative les vols de cargaison et notamment les vols d’embarcation, de telles embarcations pouvant rester habituellement plusieurs mois en stationnement sur la remorque, notamment l’hiver. Une telle configuration de stationnement limite par ailleurs l’usure des pneumatiques des roues et des essieux. Such a configuration makes it possible to significantly limit the theft of cargo and in particular the theft of boat, such boats being able to remain usually several months parked on the trailer, in particular in winter. Such a parking configuration also limits the wear of the tires of the wheels and axles.
Avantageusement, l’essieu avant et le système de chenilles sont chacun montés sur ladite structure porteuse par l’intermédiaire respectivement d’un premier et d’un deuxième bras articulés structurellement indépendants et actionnables par lesdits moyens de commande. Avantageusement, les premier et deuxième bras articulés comportent chacun deux bielles en parallèle montées à pivotement entre la structure porteuse et respectivement l’essieu avant et le système de chenilles, chacune desdites deux bielles étant actionnables respectivement par un premier et un deuxième systèmes de vérins. Advantageously, the front axle and the track system are each mounted on said supporting structure by means of a first and a second articulated arm, structurally independent and actuable by said control means, respectively. Advantageously, the first and second articulated arms each comprise two connecting rods in parallel mounted to pivot between the supporting structure and respectively the front axle and the track system, each of said two connecting rods being actuatable respectively by a first and a second cylinder systems.
On comprend ici qu’une telle configuration de bras articulés avec deux bielles montés, parallèles entre elles, à pivotement entre la structure et respectivement l’essieu avant et le système de chenilles permet de former pour chaque bras un parallélogramme déformable sous l’action des vérins. It is understood here that such a configuration of articulated arms with two connecting rods mounted, parallel to each other, to pivot between the structure and respectively the front axle and the track system makes it possible to form for each arm a deformable parallelogram under the action of jacks.
De préférence, les premier et deuxième systèmes de vérins sont hydrauliques. De préférence, les moyens de commande sont configurés pour actionner les premier et deuxième systèmes de vérins de manière à permettre, en configuration autonome, un réglage en hauteur et/ou réglage de rinclinaison de ladite structure porteuse vers l’avant ou rarrière. La possibilité de régler la hauteur et/ou rinclinaison de la structure porteuse permet d’améliorer les opérations de mise à l’eau et de remontée par exemple. Preferably, the first and second cylinder systems are hydraulic. Preferably, the control means are configured to actuate the first and second systems of jacks so as to allow, in autonomous configuration, a height adjustment and / or adjustment of the inclination of said carrying structure towards the front or towards the rear. The possibility of adjusting the height and / or inclination of the supporting structure makes it possible to improve the launching and lifting operations, for example.
Dans un mode de réalisation avantageux de la présente invention, on prévoit que chacune des roues arrière intègre un système de freinage, un caisson étanche étant mis en œuvre lors de l’escamotage desdites roues arrière pour protéger le système de freinage. In an advantageous embodiment of the present invention, provision is made for each of the rear wheels to incorporate a braking system, a sealed box being implemented when said rear wheels are retracted to protect the braking system.
Dans ce mode, on prévoit préférentiellement que le système de freinage de chaque roue arrière est positionné à l’intérieur d’une coupole formant une cloche et logée dans le volume défini par la jante de ladite roue arrière. In this mode, provision is preferably made for the braking system of each rear wheel to be positioned inside a dome forming a bell and housed in the volume defined by the rim of said rear wheel.
Avantageusement, le caisson étanche est mis en œuvre pour chaque roue arrière par un ensemble formé par un joint gonflable et un flasque porte joint formant une coupelle. Advantageously, the sealed box is implemented for each rear wheel by an assembly formed by an inflatable seal and a seal holder flange forming a cup.
Préférentiellement, le flasque porte joint couvre la portion supérieure de la coupole de manière à laisser en configuration de route un espace périphérique entre le bord périphérique interne de la coupole et le flasque. Un tel espace est nécessaire pour permettre à la roue de tourner librement. Preferably, the seal carrying flange covers the upper portion of the dome so as to leave, in the road configuration, a peripheral space between the internal peripheral edge of the dome and the flange. Such a space is necessary to allow the wheel to turn freely.
Avantageusement, le joint gonflable est logé le long d’une gorge périphérique s’étendant sur le bord périphérique externe du flasque porte joint, ladite gorge étant en regard du bord périphérique interne de ladite coupole. Advantageously, the inflatable seal is housed along a peripheral groove extending over the outer peripheral edge of the seal carrier flange, said groove facing the inner peripheral edge of said dome.
Avantageusement, les moyens de commande sont configurés pour, lors du passage de la configuration de route à la configuration autonome, actionner le joint gonflable de manière à ce que ledit joint se gonfle pour s’expanser jusqu’à venir en contact avec le bord périphérique interne de ladite coupole afin d’obstruer l’espace périphérique entre le bord périphérique interne de ladite coupole et le flasque pour fermer hermétiquement le volume, défini par ladite coupole et ledit flasque, logeant le système de freinage. Advantageously, the control means are configured to, during the passage from the road configuration to the autonomous configuration, actuate the inflatable seal so that said seal inflates to expand until it comes into contact with the peripheral edge. internal of said cupola in order to obstruct the peripheral space between the internal peripheral edge of said cupola and the flange to hermetically close the volume, defined by said cupola and said flange, housing the braking system.
Corrélativement, l’objet de la présente invention concerne selon un deuxième aspect une utilisation d’une remorque telle que celle décrite ci-dessus dans laquelle la cargaison comprend un engin nautique de type embarcation légère, ladite remorque assurant un déplacement de l’engin sur terre et sa mise à l’eau. Alternativement, l’objet de la présente invention concerne selon un troisième aspect une utilisation d’une remorque telle que celle décrite ci-dessus dans laquelle ladite cargaison comprend une pluralité de rondins de bois. Correspondingly, the object of the present invention relates according to a second aspect to a use of a trailer such as that described above in which the cargo comprises a nautical vehicle of the light craft type, said trailer ensuring movement of the vehicle over land and its launch. Alternatively, the object of the present invention relates according to a third aspect to a use of a trailer such as that described above in which said cargo comprises a plurality of wooden logs.
Ainsi, par ses différentes caractéristiques techniques fonctionnelles et structurelles décrites ci- dessus, la présente invention permet la conception d’une remorque hybride permettant notamment le déplacement d’une cargaison dans plusieurs situations en zone carrossable et/ou non carrossable. Thus, by virtue of its various technical, functional and structural characteristics described above, the present invention allows the design of a hybrid trailer allowing in particular the movement of cargo in several situations in drivable and / or non-drivable areas.

Detailed description according to an advantageous embodiment
Une remorque selon un exemple de réalisation de la présente invention va maintenant être décrite dans ce qui va suivre en référence conjointement aux figures 1 à 7A-7B. A trailer according to an exemplary embodiment of the present invention will now be described in what follows with reference in conjunction to Figures 1 to 7A-7B.
On comprendra ici que la présente description qui va suivre porte principalement sur une utilisation de la remorque pour les engins nautiques tels que par exemple les embarcations légères. It will be understood here that the present description which follows relates mainly to a use of the trailer for nautical vehicles such as for example light boats.
Une telle remorque est en effet particulièrement adaptée pour la manutention sur terre et la mise à l’eau d’une embarcation légère. Such a trailer is in fact particularly suitable for handling on land and launching a light craft.
Bien évidemment, on comprendra que d’autres exemples d’applications avantageuses pourront être envisagés dans le cadre de la présente invention. Obviously, it will be understood that other examples of advantageous applications could be envisaged within the framework of the present invention.
Dans le domaine de la navigation de plaisance ou plus généralement dans le domaine de la navigation sur des embarcations légères, il peut s’avérer utile pour le navigateur de pouvoir amener lui-même son embarcation jusqu’au plan d’eau. In the field of pleasure boating or more generally in the field of navigation on light craft, it may prove useful for the navigator to be able to bring his craft himself to the body of water.
Dans certaines situations, celui-ci n’a pas nécessairement recours aux installations que l’on retrouve classiquement dans les ports ou les embarcadères (rampe de mise à l'eau, moyens de levage, etc.). In certain situations, it does not necessarily use the facilities that are conventionally found in ports or piers (launching ramp, lifting equipment, etc.).
Dans ce genre de situations, on connaît l’utilisation de véhicules spécialement dédiées pour l’accès au plan d'eau. In this type of situation, we know the use of specially dedicated vehicles for access to the water.
Ces véhicules sont par exemple ceux décrits dans les documents mentionnés dans le préambule de la description tels que par exemple les documents EP1561637A1, EP2402210A2 et GB2419853A. Ces véhicules sont capables de circuler avec leur cargaison dans des zones non carrossables. These vehicles are for example those described in the documents mentioned in the preamble of the description such as for example the documents EP1561637A1, EP2402210A2 and GB2419853A. These vehicles are able to circulate with their cargo in non-drivable areas.
En revanche, il est nécessaire de charger l’embarcation de la remorque vers ce type de véhicule pour pouvoir franchir la zone non carrossable, ce qui nécessite des manipulations longues et complexes. On the other hand, it is necessary to load the boat from the trailer to this type of vehicle in order to be able to cross the non-drivable area, which requires long and complex operations.
Un des objectifs de la présente invention consiste donc à proposer la conception d’une remorque hybride 100 comprenant des moyens cinématiques lui permettant de présenter plusieurs types de configuration dont : One of the objectives of the present invention therefore consists in proposing the design of a hybrid trailer 100 comprising kinematic means allowing it to have several types of configuration including:
- une configuration de route, notée ici C 1 , - a road configuration, noted here C 1,
une configuration autonome, notée ici C2, et an autonomous configuration, noted here C2, and
une configuration de stationnement, notée ici C3. a parking configuration, denoted here C3.
La configuration de route Cl, illustrée par exemple en figure 3, correspond à une configuration de remorque classique qui permet à ladite remorque 100 d’être tirée par un véhicule tracteur (non représenté ici) via un système d’attelage fixé à l’avant du timon de la remorque 100. La configuration de route Cl permet donc au véhicule tracteur de déplacer la remorque 100 en zone carrossable. The road configuration C1, illustrated for example in FIG. 3, corresponds to a conventional trailer configuration which allows said trailer 100 to be pulled by a towing vehicle (not shown here) via a coupling system attached to the front. drawbar of the trailer 100. The Cl road configuration therefore allows the tractor vehicle to move the trailer 100 in a drivable area.
La configuration autonome C2, illustrée par exemple en figure 4, correspond à une configuration de remorque mettant en œuvre des moyens de motorisation embarqués dans la remorque 100 ; ici par exemple un système de chenilles 30, pour permettre un déplacement autonome de la remorque 100 dans une zone non carrossable. Une telle configuration C2 autonome facilite la traversée d’une zone non carrossable telle que par exemple une zone telle qu’une prairie séparant la route du rivage, une plage de sable (notamment à marée basse) ou encore une zone présentant un sol meuble qui, par nature, est difficile d’accès à un véhicule ou à une remorque. The autonomous configuration C2, illustrated for example in FIG. 4, corresponds to a trailer configuration implementing motorization means on board the trailer 100; here, for example, a track system 30, to allow autonomous movement of the trailer 100 in a non-drivable zone. Such an autonomous C2 configuration makes it easier to cross a non-drivable area such as for example an area such as a meadow separating the road from the shore, a sandy beach (especially at low tide) or even an area with loose soil which , by nature, is difficult to access a vehicle or trailer.
La configuration de stationnement C3, illustrée par exemple en figures 2 et 5, correspond quant à elle à une configuration de remorque 100 dont la structure porteuse 10 servant de châssis est à même le sol de sorte à ce qu’il devient très difficile, voire même impossible, pour une personne malintentionnée d’atteler la remorque à son véhicule pour voler la cargaison qu’elle contient. Ce type de vol est très fréquent dans les zones de stationnement où sont stockées les embarcations, notamment en période hivernale. The parking configuration C3, illustrated for example in Figures 2 and 5, for its part corresponds to a trailer configuration 100 whose supporting structure 10 serving as a chassis is on the ground so that it becomes very difficult, or even even impossible, for a malicious person to hitch the trailer to his vehicle to steal the cargo it contains. This type of theft is very common in parking areas where boats are stored, especially during the winter.
Dans l’exemple décrit ici et illustré dans les différentes figures, la remorque 100 selon la présente invention comporte une structure porteuse 10 qui sert de châssis. In the example described here and illustrated in the various figures, the trailer 100 according to the present invention comprises a supporting structure 10 which serves as a frame.
Une telle structure 10 est de préférence réalisée dans des matériaux résistants tels que des matériaux métalliques ayant reçu en outre une traitement anticorrosion ou des matériaux composites. Such a structure 10 is preferably made of resistant materials such as metallic materials having additionally received an anti-corrosion treatment or composite materials.
Une telle structure porteuse 10 comprend des moyens configurés pour supporter et assurer le maintien en position de la cargaison et plus particulièrement ici de l’embarcation. Such a supporting structure 10 comprises means configured to support and ensure the maintenance in position of the cargo and more particularly here of the boat.
Dans les figures illustrées ici, de tels moyens ne sont pas représentés. Il peut s’agir de tout type de moyens conçus pour recevoir une portion de la coque de l’embarcation et maintenir en position celle-ci sur ladite structure porteuse. In the figures illustrated here, such means are not shown. This can be any type of means designed to receive a portion of the hull of the boat and hold it in position on said supporting structure.
Ces moyens ne font pas l’objet de l’invention et ne seront pas décrits ni illustrés davantage. These means are not the subject of the invention and will not be further described or illustrated.
La structure porteuse 10 selon la présente invention comprend des moyens de déplacement. Dans l’exemple décrit ici, un essieu arrière 20 comprenant deux demi-essieux, un essieu avant 40 et un système de chenilles 30 motorisés sont montés sur ladite structure porteuse 10. The supporting structure 10 according to the present invention comprises displacement means. In the example described here, a rear axle 20 comprising two half-axles, a front axle 40 and a motorized track system 30 are mounted on said supporting structure 10.
Ces moyens de déplacement sont caractéristiques de la présente invention en ce qu’ils sont montés mobiles sur la structure porteuse 10 de manière à être rendus actifs ou inactifs en fonction de la configuration de remorque souhaitée. Dans cet exemple, les deux demi-essieux arrière 20 comprennent chacun une paire de roues arrière 21 escamotables. On comprend ici que, lors de l’escamotage des roues arrière 21, celles- ci viennent se loger à l’horizontal sous la structure porteuse 10, comme illustré en figure 4. L’escamotage des roues arrière 21 est possible par la mise en œuvre de vérins (non représentés ici) dont l’actionnement assure un pivotement de chacune des roues par rapport à la structure porteuse 10 de manière à ce que celles-ci passent d’une position dans laquelle l’axe de la roue est parallèle au sol pour permettre le roulement des roues sur le sol à une position dans laquelle l’axe de la roue est perpendiculaire au sol afin que la partie active des pneumatiques ne soit plus en contact avec le sol. These displacement means are characteristic of the present invention in that they are movably mounted on the supporting structure 10 so as to be made active or inactive depending on the desired trailer configuration. In this example, the two rear half-axles 20 each comprise a pair of retractable rear wheels 21. It is understood here that, when the rear wheels 21 are retracted, they are housed horizontally under the supporting structure 10, as illustrated in FIG. 4. The retraction of the rear wheels 21 is possible by the setting in work of jacks (not shown here) whose actuation ensures a pivoting of each of the wheels relative to the supporting structure 10 so that they pass from a position in which the axis of the wheel is parallel to the ground to allow the wheels to run on the ground at a position in which the axis of the wheel is perpendicular to the ground so that the active part of the tires is no longer in contact with the ground.
L’homme du métier comprendra ici qu’il pourra envisager tous les moyens d’escamotage possibles dans le cadre de la présente invention pour escamoter les roues arrière 21 sous la structure porteuse 10. Those skilled in the art will understand here that they can consider all possible retraction means within the framework of the present invention to retract the rear wheels 21 under the supporting structure 10.
Dans cet exemple, l’essieu avant 40 comprend une paire de roue avant directionnelles 41 qui sont rétractables. In this example, the front axle 40 includes a pair of directional front wheels 41 which are retractable.
Dans cet exemple, l’essieu avant 40 et le système de chenilles 30 sont tous les deux montés sur la structure porteuse 10 par l’intermédiaire respectivement d’un premier 42 et d’un deuxième 31 bras articulés. In this example, the front axle 40 and the track system 30 are both mounted on the supporting structure 10 via a first 42 and a second 31 articulated arms respectively.
Dans cet exemple, et comme illustré en notamment en figure 4, les premier 42 et deuxième 31 bras articulés comportent chacun deux bielles respectivement 42a et 31a montées en parallèle. Ce système de bielles est monté à pivotement entre la structure porteuse 10 et respectivement l’essieu avant 40 et le système de chenilles 30 pour former un parallélogramme déformable. In this example, and as illustrated in particular in FIG. 4, the first 42 and second 31 articulated arms each comprise two connecting rods 42a and 31a respectively mounted in parallel. This connecting rod system is pivotally mounted between the supporting structure 10 and respectively the front axle 40 and the track system 30 to form a deformable parallelogram.
La déformation de ce parallélogramme est réalisée par l’actionnement d’un premier 43 et d’un deuxième 32 systèmes de vérins hydrauliques respectivement pour le premier 42 et le deuxième 31 bras articulés. The deformation of this parallelogram is achieved by actuating a first 43 and a second 32 hydraulic cylinder systems respectively for the first 42 and the second 31 articulated arms.
L’actionnement des vérins hydrauliques permet alors le réglage en hauteur et/ou en inclinaison de la structure porteuse 10 dans la mesure où les bras articulés sont bien structurellement indépendants les uns des autres. The actuation of the hydraulic cylinders then allows the height and / or inclination of the supporting structure 10 to be adjusted as long as the articulated arms are structurally independent from each other.
Il est ainsi possible de faire varier l’inclinaison du châssis (le tangage) soit vers l’avant, soit vers l’arrière ; ceci permet d’améliorer de façon significative le franchissement d’obstacle ou la mise à l’eau ou encore de compenser la pente d’inclinaison lors de la récupération de l’embarcation. Il sera également possible de gérer le roulis du fait de l’indépendance des bras du système de chenille et de la torsion de l’essieu avant. It is thus possible to vary the inclination of the chassis (the pitch) either forwards or backwards; this significantly improves obstacle clearance or launching or compensates for the inclination slope when recovering the boat. It will also be possible to manage the roll due to the independence of the arms of the track system and the torsion of the front axle.
Dans le cadre de la présente invention, on dispose de moyens de commande 50. Il peut s’agir par exemple d’un boîtier électronique disposé sur la partie avant du timon, un tel boîtier pouvant comprendre une carte électronique programmée comprenant des instructions pour commander l’actionnement des moyens d’escamotage et des bras articulés afin de placer la remorque 100 dans une configuration ou dans une autre en fonction de la situation et de l’usage souhaité.In the context of the present invention, control means 50 are available. This may for example be an electronic box arranged on the front part of the drawbar, such a box being able to comprise a programmed electronic card comprising instructions for controlling the actuation of the retraction means and of the articulated arms in order to place the trailer 100 in one configuration or in another depending on the situation and the desired use.
Les moyens de commande 50 peuvent donc être électriquement reliés aux organes de déplacement susmentionnés, à savoir notamment les moyens d’escamotage et les bras articulés. Alternativement, on pourra prévoir une commande par des moyens sans fil. The control means 50 can therefore be electrically connected to the aforementioned displacement members, namely in particular the retraction means and the articulated arms. Alternatively, it is possible to provide a command by wireless means.
Les moyens de commande 50 pourront comprendre des manettes et/ou des boutons poussoirs configurés pour permettre l’actionnement de la remorque 100 dans une configuration ou dans l’autre ainsi que le guidage de la remorque 100 dans ses déplacements (guidage des roues directionnelles avant par exemple et/ou guidage du système de chenilles et de la motorisation par exemple). The control means 50 may comprise levers and / or push buttons configured to allow the actuation of the trailer 100 in one configuration or the other as well as the guidance of the trailer 100 in its movements (guiding the front directional wheels for example and / or guiding the track system and the motorization for example).
Dans l’exemple décrit ici et illustré en figure 3, la remorque 100 est dans sa configuration de route Cl . On se place ici dans une situation classique dans laquelle l’utilisateur de la remorque 100 a transporté son embarcation sur la route jusqu’à un parking (zone carrossable) à proximité d’une zone d’embarcation pour la mise à l’eau. In the example described here and illustrated in Figure 3, the trailer 100 is in its C1 road configuration. Here we are in a conventional situation in which the user of the trailer 100 has transported his boat on the road to a parking lot (drivable area) near a boat area for launching.
Dans cette configuration, les roues arrière 21 sont en contact avec le sol, ce qui a permis le déplacement de l’embarcation jusqu’à cette zone en attelant la remorque à un véhicule tracteur via un système d’attelage. In this configuration, the rear wheels 21 are in contact with the ground, which made it possible to move the craft to this area by coupling the trailer to a towing vehicle via a hitch system.
Ici, on comprend que cette zone de parking est cependant séparée de la zone d’embarcation par une zone non carrossable (une prairie ou une plage de sable à marée basse), une telle situation étant classique. Here, we understand that this parking area is however separated from the boat area by a non-drivable area (a meadow or a sandy beach at low tide), such a situation being classic.
La remorque selon la présente invention est configurée pour surmonter un tel obstacle, ce qui n’est pas possible avec les solutions actuelles de l’état de la technique. The trailer according to the present invention is configured to overcome such an obstacle, which is not possible with the current solutions of the state of the art.
L’utilisateur par l’intermédiaire des moyens de commande 50 peut en effet actionner le premier système de vérins hydrauliques 43 pour rehausser la partie avant de la structure porteuse 10 ainsi que le deuxième système de vérins hydraulique 32 pour rehausser la partie arrière de la structure porteuse 10 de sorte à ce que les roues avant 41 et le système de chenilles 30 soient en contact avec le sol. The user via the control means 50 can in fact actuate the first system of hydraulic cylinders 43 to raise the front part of the supporting structure 10 as well as the second system of hydraulic cylinders 32 to raise the rear part of the structure. carrier 10 so that the front wheels 41 and the track system 30 are in contact with the ground.
Les moyens de commande 50 sont configurés pour actionner dans le même temps les moyens d’escamotage de manière à ce que les roues arrière 21 soient escamotées sous la structure porteuse 10 et ne soient plus en contact avec le sol. The control means 50 are configured to simultaneously actuate the retraction means so that the rear wheels 21 are retracted under the supporting structure 10 and are no longer in contact with the ground.
La remorque 100 se positionne alors dans sa configuration autonome C2 et peut se déplacer de façon autonome dans la zone non carrossable via le système de chenilles 30 motorisés et l’essieu avant 40. On comprend ici que le système de chenilles 30 intègre des moyens de motorisation (hydrauliques, électriques ou autres) permettant l’actionnement des chenilles pour les déplacements dans les zones non carrossables. The trailer 100 is then positioned in its autonomous configuration C2 and can move independently in the non-drivable zone via the motorized track system 30 and the front axle 40. It is understood here that the track system 30 incorporates means of motorization (hydraulic, electric or other) allowing the actuation of the tracks for movement in areas not suitable for vehicles.
Alternativement, on peut également considérer que 1 'utilisateur souhaite stationner de façon prolongée son embarcation 100 sur cette zone de parking. Alternatively, it can also be considered that the user wishes to park his boat 100 for a prolonged period in this parking area.
La présente invention prévoit dans ce cas la possibilité de positionner la remorque dans une configuration de stationnement C3 (illustré en figure 5) qui limite de façon significative les risques de vol. The present invention in this case provides for the possibility of positioning the trailer in a C3 parking configuration (illustrated in FIG. 5) which significantly limits the risks of theft.
Dans cette situation, l’utilisateur peut en effet via les moyens de commande positionner la remorque 100 en configuration de stationnement C3 de manière à rétracter les roues avant 41 et le système de chenilles 30 tout en escamotant les roues arrière 21. In this situation, the user can in fact via the control means position the trailer 100 in the parking configuration C3 so as to retract the front wheels 41 and the track system 30 while retracting the rear wheels 21.
La structure porteuse 10 de la remorque est directement en appui sur le sol dans cette configuration C3, ce qui empêche un voleur d’atteler la remorque à son véhicule et de l’emporter frauduleusement. The supporting structure 10 of the trailer rests directly on the ground in this C3 configuration, which prevents a thief from hitching up the trailer to his vehicle and carrying it away fraudulently.
Une telle configuration est particulièrement appréciée dans ce type d’application ; les coûts d’une embarcation sont en effet très élevés et il est facile jusqu’à présent pour les voleurs d’atteler la remorque sur laquelle repose l’embarcation en mode parking prolongé lors d’une période d’inactivité (période hivernale par exemple). Such a configuration is particularly appreciated in this type of application; the costs of a boat are indeed very high and it is easy until now for thieves to hitch the trailer on which the boat rests in extended parking mode during a period of inactivity (winter period for example ).
La présente invention a également pour objet de protéger le système de freinage (ici exemple de tambour) des roues arrière lorsque celles-ci sont escamotées et que la remorque 100 est susceptible, en configuration autonome C2, de rouler dans l’eau. Another object of the present invention is to protect the braking system (here example of a drum) of the rear wheels when they are retracted and when the trailer 100 is capable, in autonomous configuration C2, of rolling in water.
En effet, le système de freinage intégré dans les roues arrière 21 comprend des pièces mécaniques (tambour de frein, disque de frein, etc.) qui sont susceptibles de se détériorer au contact de l’eau et notamment de l’eau de mer. Indeed, the braking system integrated in the rear wheels 21 includes mechanical parts (brake drum, brake disc, etc.) which are liable to deteriorate on contact with water and in particular sea water.
Ceci n’est pas souhaitable pour des raisons évidentes de sécurité puisque cela mettrait en danger l’utilisateur de la remorque dont le freinage serait dégradé. This is undesirable for obvious safety reasons since it would endanger the user of the trailer whose braking would be degraded.
Pour remédier à cette problématique, la présente invention prévoit la mise en œuvre d’un caisson étanche 60 lors de l’escamotage des roues arrière 21. To remedy this problem, the present invention provides for the implementation of a sealed box 60 when the rear wheels 21 are retracted.
Dans l’exemple décrit ici et illustré en figures 6A-6B et 7A-7B, le système de freinage de chaque roue arrière 21 est positionné à l’intérieur d’une coupole 61 qui forme une cloche de protection ; cette cloche est logée dans le volume défini par la jante 21a de la roue arrière 21. Dans cet exemple, la mise en œuvre du caisson étanche 60 est rendue possible par un ensemble formé par un joint gonflable 62, un flasque porte joint 63 et la coupole 61. Dans l’exemple décrit ici, le joint gonflable 62 est logé le long d’une gorge périphérique 63b s’étendant sur le bord périphérique externe 63a dudit flasque porte joint 63, ladite gorge 63b étant en regard du bord périphérique interne 61a de ladite coupole 61. In the example described here and illustrated in FIGS. 6A-6B and 7A-7B, the braking system of each rear wheel 21 is positioned inside a dome 61 which forms a protective bell; this bell is housed in the volume defined by the rim 21a of the rear wheel 21. In this example, the implementation of the sealed box 60 is made possible by an assembly formed by an inflatable seal 62, a seal holder flange 63 and the cupola 61. In the example described here, the inflatable seal 62 is housed along a peripheral groove 63b extending over the outer peripheral edge 63a of said seal carrier flange 63, said groove 63b being opposite the inner peripheral edge 61a of said cupola. 61.
On dispose, en configuration de route Cl, d’un espace périphérique EP entre le bord périphérique interne 61a de la coupole 61 et le bord périphérique externe 63a dudit flasque 63 (voir figure 6B). Un tel espace EP permet la mise en rotation de la roue sur elle-même selon l’axe de la fusée de roue. In the road configuration C1, there is a peripheral space EP between the internal peripheral edge 61a of the dome 61 and the external peripheral edge 63a of said flange 63 (see FIG. 6B). Such an EP space allows the wheel to rotate on itself along the axis of the wheel spindle.
En obstruant cet espace EP, le volume défini par la coupole 61 et le flasque 63 qui loge le système de freinage devient étanche. By obstructing this space EP, the volume defined by the dome 61 and the flange 63 which houses the braking system becomes sealed.
Les moyens de commande 50 sont donc configurés pour, lors du passage de la configuration de route Cl à la configuration autonome C2, actionner le joint gonflable 62 de manière à ce que ledit joint 62 se gonfle pour s’expanser jusqu’à venir en contact avec le bord périphérique interne 61a de la coupole 61 afin d’obstruer ledit espace périphérique EP (voir figure 7B) et ainsi fermer hermétiquement le volume, défini par la coupole 61 et le flasque 63. The control means 50 are therefore configured to, during the passage from the road configuration C1 to the autonomous configuration C2, actuate the inflatable seal 62 so that said seal 62 inflates to expand until it comes into contact. with the internal peripheral edge 61a of the dome 61 in order to obstruct said peripheral space EP (see FIG. 7B) and thus hermetically close the volume, defined by the dome 61 and the flange 63.
On pourra également prévoir un capteur logé par exemple au niveau de la roue 21 (par exemple la jante 21a) et qui est capable de détecter que la remorque 100 pénètre dans l’eau. A sensor could also be provided, for example housed at the level of the wheel 21 (for example the rim 21a) and which is capable of detecting that the trailer 100 is entering the water.
Un tel capteur peut alors générer un signal d’avertissement à destination des moyens de commande 50 de manière à ce que ceux-ci déclenchent l’actionnement du joint gonflable 62 de chacune des roues uniquement en cas d’immersion. Such a sensor can then generate a warning signal intended for the control means 50 so that the latter trigger the actuation of the inflatable seal 62 of each of the wheels only in the event of immersion.
La présente invention prévoit donc la mise en œuvre d’un caisson étanche 60 visant spécifiquement à protéger le système de freinage des roues en cas d’immersion. The present invention therefore provides for the implementation of a sealed box 60 aimed specifically at protecting the braking system of the wheels in the event of immersion.
La remorque 100 développée dans le cadre de la présente invention permet à la fois le transport d’une embarcation par la route de manière traditionnelle (configuration de route Cl illustrée en figure 3), la transformation de celle-ci en un engin autonome, tout-terrain et amphibie (configuration autonome C2 illustrée en figure 4) et enfin le stationnement à plat sur le châssis (configuration de stationnement C3 illustrée en figure 5) sans qu’aucun des organes de roulage ne touche le sol ce qui permet non seulement d’éviter le vol mais préserve également ces organes de toute usure prématurée lors d’un stationnement prolongé ; de plus, dans cette configuration C3, l’escamotage du train routier à l’horizontal permet de conserver l’espace de chargement au plus près des roues et maintenir ainsi le centre de gravité de la charge le plus bas possible, contrairement à un escamotage vertical. The trailer 100 developed within the framework of the present invention allows both the transport of a boat by road in a traditional manner (road configuration C1 illustrated in FIG. 3), the transformation of the latter into an autonomous vehicle, while -terrain and amphibious (autonomous configuration C2 illustrated in figure 4) and finally the parking flat on the chassis (parking configuration C3 illustrated in figure 5) without any of the rolling members touching the ground which not only allows 'avoid theft but also protects these components from any premature wear during prolonged parking; moreover, in this C3 configuration, retracting the road train horizontally makes it possible to keep the load space as close as possible to the wheels and thus keep the center of gravity of the load as low as possible, unlike retraction vertical.
La remorque 100 développée dans le cadre de la présente invention permet également lorsqu’elle est en configuration autonome C2 de faire varier la hauteur de roulage et donc de modifier la garde au sol, d’incliner le châssis vers l’avant ou vers l’arrière, de franchir des obstacles sans que le l’ensemble roulant ne bascule d’un seul coup lorsque le centre de gravité de l’ensemble franchit la zone de sustentation. The trailer 100 developed within the framework of the present invention also makes it possible, when it is in autonomous configuration C2, to vary the rolling height and therefore to modify the ground clearance, to tilt the chassis forwards or forwards. rear, to cross obstacles without the rolling assembly tipping all at once when the center of gravity of the assembly crosses the lift zone.
La présente invention propose donc une conception innovante de remorque 100 qui offre de nombreux avantages tels que notamment : The present invention therefore proposes an innovative design of trailer 100 which offers numerous advantages such as in particular:
l’immersion partielle ou totale de la remorque dans l’eau ; partial or total immersion of the trailer in water;
la protection des freins dans un caisson étanche évitant la corrosion prématurée des pièces mécaniques des freins (tambour, disque, etc.) ; protection of the brakes in a sealed box preventing the premature corrosion of mechanical parts of the brakes (drum, disc, etc.);
la rétraction du train routier à l’horizontale pour conserver l’intégrité totale de l’espace de chargement sans devoir relever le centre de gravité de la charge et donc assurer une tenue de route optimum, retraction of the road train horizontally to maintain the total integrity of the load space without having to raise the load's center of gravity and therefore ensure optimum road holding,
G inclinaison du châssis vers l’avant ou vers l’arrière ; G tilting the chassis forward or backward;
le franchissement des obstacles en douceur sans basculer la remorque lorsque par exemple le centre de gravité de l’ensemble dépasse la surface de sustentation ; the smooth crossing of obstacles without tipping the trailer when, for example, the center of gravity of the assembly exceeds the support surface;
le déplacement de la remorque en positionnant le châssis de manière à ce que celui-ci soit très près du sol pour réduire la hauteur par exemple lorsqu’il faut rentrer dans un garage ; moving the trailer by positioning the frame so that it is very close to the ground to reduce the height, for example when entering a garage;
une protection anti-vol en configuration stationnement ; anti-theft protection in parking configuration;
la réduction des risques d’enlisement en assurant les déplacements par le système de chenilles motorisé en configuration autonome reducing the risk of getting bogged down by ensuring movement by the motorized track system in autonomous configuration
la possibilité de remplacer une roue crevée sans cric. the possibility of replacing a punctured wheel without a jack.
Ainsi, le Demandeur considère que la présente invention grâce à cette conception de remorque innovante permet de combiner l’ensemble des fonctionnalités de l’art antérieur en y ajoutant des fonctionnalités nouvelles. Thus, the Applicant considers that the present invention, thanks to this innovative trailer design, makes it possible to combine all the functionalities of the prior art by adding new functionalities thereto.
