Description

CHARIOT REPLIABLE POUR LE TRANSPORT D'OBJETS DIVERS.FOLDABLE TROLLEY FOR THE TRANSPORT OF VARIOUS OBJECTS.
La présente invention concerne un chariot ou une remorque repliable utilisable pour le transport d'objets divers.The present invention relates to a folding cart or trailer usable for transporting various objects.
Elle s'applique notamment mais non exclusivement au transport d'objets allongés tels que des embarcations.It applies in particular but not exclusively to the transport of elongated objects such as boats.
D'une manière générale, on sait que les chariots de transport et/ou de manutention d'embarcations sont habituellement constitués par un châssis porteur sur lequel est fixé au moins un train de roues. L'avant du châssis est équipé d'un dispositif d'attelage permettant le remorquage par un véhicule tracteur.In general, it is known that the transport and / or handling carts for boats are usually constituted by a carrying frame on which is fixed at least one set of wheels. The front of the chassis is equipped with a coupling device allowing towing by a towing vehicle.
L'inconvénient de ces chariots résulte de leur longueur (plusieurs mètres) qui dépasse fréquemment celle d'une voiture de tourisme, de sorte que des problèmes de stationnement se posent aussi bien lorsque le chariot n'est pas utilisé que lorsqu'il est attaché à un véhicule de traction.The disadvantage of these trolleys results from their length (several meters) which frequently exceeds that of a passenger car, so that parking problems arise both when the trolley is not used and when it is attached to a traction vehicle.
Pour résoudre ce problème, le Demandeur a déjà proposé un chariot du type susdit présentant une longueur et un encombrement considérablement réduits lorsque le chariot n'est pas en cours d'utilisation et qui est au moins aussi robuste et facile d'utilisation que les chariots de transport connus dans l'état actuel de la technique. A cet effet, le châssis de ce chariot comporte une partie principale pourvue de roues et au moins une partie escamotable mobile par rapport à la partie principale entre une position escamotée et une position déployée. Plus précisément, sur les bordures antérieures et postérieures de l'élément principal du châssis (ici la partie centrale) viennent respectivement s'articuler une partie avant et une partie arrière, ces deux parties pouvant prendre une position déployée dans laquelle elles s'étendent dans le prolongement de l'élément principal du châssis, selon l'axe longitudinal de celui-ci et une position escamotée dans laquelle elles sont rabattues l'une sur l'autre, sur l'élément principal.To solve this problem, the Applicant has already proposed a trolley of the above type having a considerably reduced length and size when the trolley is not in use and which is at least as robust and easy to use as the trolleys transport known in the current state of the art. To this end, the chassis of this carriage comprises a main part provided with wheels and at least one retractable part movable relative to the main part between a retracted position and a deployed position. More specifically, on the front and rear edges of the main element of the chassis (here the central part) are articulated respectively a front part and a rear part, these two parts being able to assume a deployed position in which they extend in the extension of the main element of the chassis, along the longitudinal axis of the latter and a retracted position in which they are folded over one another, on the main element.
L'invention a plus particulièrement pour but d'améliorer ce type de chariot de manière à pouvoir réduire davantage sa longueur à l'état replié, sans pour autant avoir à réduire sa longueur à l'état déployé.The invention more particularly aims to improve this type of carriage so as to be able to further reduce its length in the folded state, without having to reduce its length in the deployed state.
Elle s'applique tout particulièrement dans le cas d'un chariot comprenant un élément central de faible longueur, un élément arrière articulé sur la partie centrale et un élément avant incorporant un timon et présentant une longueur importante terminée par des moyens d'accrochage à un véhicule (par exemple une "tête de lapin à rotule"), cet élément avant pouvant présenter, au voisinage de son extrémité, un élément d'appui (barre d'étrave) du bateau monté sur une potence fixée sur la partie supérieure du timon et une roue escamotable montée sur un bras.It is particularly applicable in the case of a carriage comprising a central element of short length, a rear element articulated on the central part and a front element incorporating a drawbar and having a significant length terminated by means of attachment to a vehicle (for example a "ball head"), this front element possibly having, near its end, a support element (bow bar) of the boat mounted on a bracket fixed on the upper part of the drawbar and a retractable wheel mounted on an arm.
Conformément à l'invention, l'élément avant comprend deux tronçons articulés l'un à l'autre, à savoir : un premier tronçon articulé à l'élément central de manière à basculer vers le haut (sens anti-horaire) et un deuxième tronçon portant les moyens d'accrochage et l'élément d'appui, ce deuxième tronçon étant articulé au premier tronçon par des moyens d'articulation permettant au deuxième tronçon de basculer vers le bas (sens horaire). Grâce à cette disposition, pour passer à l'état rétracté, on replie tout d'abord l'élément arrière partiellement sur l'élément principal puis on bascule le premier tronçon jusqu'à ce qu'il vienne en appui sur l'extrémité de l'élément arrière, en position repliée, le second tronçon étant rabattu sur le premier tronçon au cours de ce basculement.According to the invention, the front element comprises two sections articulated to each other, namely: a first section articulated to the central element so as to tilt upwards (counterclockwise) and a second section carrying the attachment means and the support element, this second section being articulated to the first section by articulation means allowing the second section to tilt down (clockwise). Thanks to this arrangement, to pass into the retracted state, first of all the rear element is partially folded over the main element and then the first section is tilted until it comes to bear on the end of the rear element, in the folded position, the second section being folded over the first section during this tilting.
Grâce à ces dispositions, la longueur du chariot en position repliée sera inférieure au tiers de sa longueur en position déployée et ce, avec un excellent centrage du centre de gravité de l'ensemble du chariot sur l'axe des roues.Thanks to these provisions, the length of the carriage in the folded position will be less than a third of its length in the deployed position, with excellent centering of the center of gravity of the entire carriage on the axis of the wheels.
De ce fait, le chariot, à l'état replié, peut donc être facilement déplacé à la main (ou par tout autre moyen) grâce à une barre de manutention ou de manipulation déployable, par exemple montée coulissante sur l'élément central du chariot.Therefore, the trolley, in the folded state, can therefore be easily moved by hand (or by any other means) thanks to a deployable handling or manipulation bar, for example sliding mounted on the central element of the trolley .
Un mode d'exécution de l'invention sera décrit ci-après, à titre d'exemple non limitatif, avec référence aux dessins annexés dans lesquels :An embodiment of the invention will be described below, by way of nonlimiting example, with reference to the appended drawings in which:
La figure 1 est une vue de côté d'un chariot à l'état déployé ;Figure 1 is a side view of a carriage in the deployed state;
Les figures 2 à 5 sont des vues de côté illustrant le principe du repliement du chariot pour passer à l'état replié : la première partie du timon étant inclinée à 30° vers le bas (figure 2), à 60° (figure 3), à 80° (figure 4) et à 120° (figure 5) ;Figures 2 to 5 are side views illustrating the principle of folding the carriage to pass in the folded state: the first part of the drawbar being inclined 30 ° downward (Figure 2), 60 ° (Figure 3) , at 80 ° (Figure 4) and 120 ° (Figure 5);
La figure 6 est une vue de côté du chariot à l'état replié.Figure 6 is a side view of the carriage in the folded state.
Tel que représenté sur ces dessins, le chariot de transport pour embarcations selon l'invention comporte un châssis comprenant un élément principal 1 de faible longueur (par exemple de l'ordre de 1 m), un élément arrière 2 de longueur inférieure à la longueur de l'élément principal 1, par exemple de l'ordre de 0,4 m et un élément avant 3 comprenant un timon, cet élément avant étant relativement long, par exemple de l'ordre de 1 ,6 m.As shown in these drawings, the boat transport trolley according to the invention comprises a chassis comprising a main element 1 of short length (for example of the order of 1 m), a rear element 2 of length less than the length of main element 1, for example of on the order of 0.4 m and a front element 3 comprising a drawbar, this front element being relatively long, for example of the order of 1.6 m.
Cet élément principal est porté, de façon classique, par au moins un train de roues coaxiales R occupant une position centrale.This main element is carried, conventionally, by at least one set of coaxial wheels R occupying a central position.
Les éléments de châssis principal 1 et arrière 2 présentent chacun une forme sensiblement rectangulaire et comprennent deux longerons latéraux entretoisés par des traverses dont au moins une à l'avant et une à l'arrière.The main chassis elements 1 and rear 2 each have a substantially rectangular shape and include two lateral beams braced by crosspieces, at least one at the front and one at the rear.
La traverse arrière 4 de l'élément arrière 2 porte un élément transversal 5 en saillie des deux côtés qui supporte, dans sa partie inférieure, la plaque d'immatriculation et les feux arrière réglementaires. La traverse avant 6 de cet élément arrière 2 est articulée à la traverse arrière 8 de l'élément principal par l'intermédiaire d'une articulation ne permettant un basculement de l'élément arrière que vers le haut dans le sens horaire. A cet effet, au niveau de cette articulation, les parties en regard des longerons des deux éléments présentent chacune une forme en T, l'articulation étant située au niveau de l'extrémité supérieure de la barre transversale du T, l'extrémité inférieure de cette barre étant utilisée pour assurer le verrouillage des deux éléments de châssis en position déployée. Grâce à cette disposition, on obtient une grande rigidité du châssis en position déployée.The rear crossmember 4 of the rear element 2 carries a transverse element 5 projecting from both sides which supports, in its lower part, the registration plate and the regulatory rear lights. The front crossmember 6 of this rear element 2 is articulated to the rear crossmember 8 of the main element by means of an articulation allowing tilting of the rear element only upwards in a clockwise direction. To this end, at this articulation, the opposite parts of the longitudinal members of the two elements each have a T-shape, the articulation being located at the upper end of the crossbar of the T, the lower end of this bar being used to lock the two chassis elements in the deployed position. Thanks to this arrangement, a high rigidity of the chassis is obtained in the deployed position.
Conformément à l'invention, l'élément avant 3 est constitué de deux tronçons successifs 9, 10. Le tronçon arrière 9 présente une structure analogue à l'élément arrière 2 mais dans laquelle les longerons sont incurvés l'un vers l'autre en direction de l'avant du chariot. Ce tronçon arrière 9 vient s'articuler sur la traverse avant 11 de l'élément de châssis principal 1. D'une façon analogue à la précédente, au niveau de cette articulation, les extrémités de chacun des longerons de l'élément central et du tronçon arrière présentent une forme en T, l'articulation s'effectuant au niveau de l'extrémité supérieure de la barre transversale du T, tandis que le verrouillage en position déployée s'effectue au niveau de l'extrémité inférieure de cette barre transversale : Grâce à cette disposition, le tronçon arrière 9 peut basculer en sens anti-horaire selon un angle d'environ 150° pour venir en butée au niveau de l'extrémité arrière de l'élément de châssis arrière 2, en position rabattue.According to the invention, the front element 3 consists of two successive sections 9, 10. The rear section 9 has a structure similar to the rear element 2 but in which the side members are curved towards one another in direction of the front of the carriage. This rear section 9 is articulated on the front cross member 11 of the main chassis element 1. In a similar manner to the previous one, at this articulation, the ends of each of the longitudinal members of the central element and of the rear section have a T-shape, the articulation being carried out at the upper end of the crossbar of the T, while the locking in the deployed position takes place at the lower end of this crossbar: Thanks to this arrangement, the rear section 9 can tilt counterclockwise at an angle of about 150 ° to come into abutment at the rear end of the rear chassis element 2, in the folded position.
Le tronçon avant 10 de l'élément avant 3 est articulé par son extrémité arrière à l'extrémité antérieure du tronçon arrière 9 au moyen d'une articulation 12 permettant d'effectuer un repliement vers le bas en sens horaire de l'élément 10 vers le tronçon 9 à partir de la position déployée de ces deux tronçons 9, 10. Pour permettre d'assurer un blocage des tronçons 9, 10 en position déployée, le tronçon de châssis 9 est muni d'une pièce d'appui 13 qui s'étend au-delà de l'articulation 12 et sur laquelle le tronçon avant 10 vient en butée en position déployée. Le verrouillage des deux tronçons 9, 10 en position déployée s'effectue entre cette pièce d'appui 13 et le tronçon 10.The front section 10 of the front element 3 is articulated by its rear end to the front end of the rear section 9 by means of a hinge 12 making it possible to fold down the element 10 towards the clockwise direction. the section 9 from the deployed position of these two sections 9, 10. To allow blocking of the sections 9, 10 in the deployed position, the chassis section 9 is provided with a support piece 13 which s 'extends beyond the joint 12 and on which the front section 10 abuts in the deployed position. The two sections 9, 10 are locked in the deployed position between this support piece 13 and the section 10.
Comme précédemment mentionné, la partie antérieure du tronçon 10 comprend à son extrémité une tête de lapin à rotule 14 destinée à venir s'accrocher sur la rotule d'un attelage à rotule d'un véhicule. Sur cette partie antérieure 10 est montée une potence 15 sur laquelle est montée une barre d'étrave 16 et, éventuellement, un treuil. Avantageusement, ce montage pourra être rotatif de manière à pouvoir effectuer le pliage de la barre d'étrave 16 et du treuil.As previously mentioned, the front part of the section 10 comprises at its end a ball-head rabbit head 14 intended to be hooked on the ball-joint of a ball-joint coupling of a vehicle. On this front part 10 is mounted a bracket 15 on which is mounted a bow bar 16 and, optionally, a winch. Advantageously, this assembly can be rotatable so as to be able to fold the bow bar 16 and the winch.
Cette partie antérieure 10 est munie d'un piètement 17 réglable en hauteur terminé par une petite roue 18.This front part 10 is provided with a height-adjustable base 17 terminated by a small wheel 18.
A partir de la position déployée illustrée sur la figure 1 , le passage en position rétractée s'effectue comme suit : Dans un premier temps, après avoir déverrouillée l'articulation, on rabat l'élément arrière 2, en sens horaire, pour l'amener au-dessus de l'élément principal 1 en le faisant basculer d'un angle d'environ 120°.From the deployed position illustrated in FIG. 1, the transition to the retracted position is carried out as follows: Firstly, after unlocking the joint, the rear element 2 is folded clockwise to bring it above the main element 1 by tilting it at an angle of approximately 120 ° .
Parallèlement, l'articulation 12 est déverrouillée, de sorte que l'élément principal 1 bascule légèrement sous le poids de l'élément avant 3 qui se trouve supporté par le piètement 17 et la roue 18.At the same time, the articulation 12 is unlocked, so that the main element 1 rocks slightly under the weight of the front element 3 which is supported by the base 17 and the wheel 18.
Le basculement de l'élément principal 1 est alors limité grâce à la présence de barres anti-cycliste 19 qui prolonge longitudinalement l'élément principal 1 vers l'arrière : L'extrémité de ces barres 19 vient en appui sur le sol en stoppant ainsi le basculement de l'élément principal 1. L'extrémité antérieure de l'élément 3 est supportée par le piètement 17 (figure 2).The tilting of the main element 1 is then limited thanks to the presence of anti-cyclist bars 19 which extend the main element 1 rearward longitudinally: The end of these bars 19 comes to bear on the ground, thus stopping the tilting of the main element 1. The front end of the element 3 is supported by the base 17 (Figure 2).
On procède alors au déverrouillage de l'articulation 12 et l'on fait basculer le tronçon 10 vers le bas (sens horaire) en vue de le rabattre contre le tronçon 9, lequel bascule vers le haut (sens anti-horaire) par rapport à l'élément principal 1. Ce double basculement se trouve facilité du fait que pendant une grande partie de la course, l'extrémité du tronçon 10 roule sur le sol grâce à la petite roue 18 (figures 3 et 4).The articulation 12 is then unlocked and the section 10 is tilted downwards (clockwise) in order to fold it against the section 9, which switches upwards (anti-clockwise) relative to the main element 1. This double tilting is facilitated by the fact that during a large part of the stroke, the end of the section 10 rolls on the ground thanks to the small wheel 18 (FIGS. 3 and 4).
Ce basculement est poursuivi jusqu'à ce que le tronçon 10 soit rabattu contre le tronçon 9, en position verticale (figure 5), puis que l'ensemble des deux tronçons 9, 10 vienne prendre appui sur la bordure postérieure de l'élément arrière 2 (figure 6). Le chariot se trouve alors en position repliée. Le maintien dans cette position est alors assuré par des moyens de verrouillage non représentés. Un bras anti-basculant 20 pourra être prévu pour maintenir le chariot dans une position angulaire voisine de celle utilisée pour le roulement du chariot. La verticale passant par le centre de gravité de cette structure passe au voisinage de l'axe de rotation des roues, côté timon, de sorte que le chariot peut être aisément manipulé à l'état replié. A cet effet, le chariot peut comprendre un bras de manipulation 21 monté dans l'élément principal 1 et s'étendant vers l'arrière.This tilting is continued until the section 10 is folded against the section 9, in the vertical position (FIG. 5), then the assembly of the two sections 9, 10 comes to bear on the rear edge of the rear element. 2 (Figure 6). The carriage is then in the folded position. Maintaining in this position is then ensured by locking means not shown. An anti-tilting arm 20 may be provided to hold the carriage in an angular position close to that used for rolling the carriage. The vertical passing through the center of gravity of this structure passes in the vicinity of the axis of rotation of the wheels, drawbar side, so that the carriage can be easily handled in the folded state. To this end, the carriage may include a handling arm 21 mounted in the main element 1 and extending rearward.
Ce bras 21 pourra être télescopique, amovible, ou fixe. A l'état déployé, il dépassera une longueur de 20 cm, par exemple 1 m, de manière à pouvoir disposer d'un bras de levier important et à réduire ainsi les efforts nécessaires pour faire basculer le chariot.This arm 21 may be telescopic, removable, or fixed. In the deployed state, it will exceed a length of 20 cm, for example 1 m, so as to be able to have a large lever arm and thus reduce the forces necessary to tilt the carriage.
Avantageusement, un système de rinçage du chariot et/ou du bateau pourra être intégré au chariot. Ce système pourra par exemple comprendre un tuyau éventuellement souple et muni d'un ou de plusieurs embouts d'adaptation, de type raccord rapide, de manière à permettre à l'utilisateur de se connecter à un réseau d'eau sans difficulté.Advantageously, a system for rinsing the cart and / or the boat can be integrated into the cart. This system could for example include a possibly flexible hose and provided with one or more adapters, of the quick coupling type, so as to allow the user to connect to a water network without difficulty.
Sur le tuyau est disposée une pluralité d'embouts d'arrosage servant à émettre chacun un jet d'eau selon une orientation prédéterminée, par exemple en direction de la coque de l'embarcation ou même d'une partie du chariot : de préférence, une partie sensible telle que des rotules, les essieux ou les tambours des roues.On the pipe is arranged a plurality of sprinkler nozzles each serving to emit a jet of water in a predetermined orientation, for example in the direction of the hull of the boat or even of a part of the carriage: preferably, a sensitive part such as ball joints, axles or wheel drums.
L'ensemble barre d'étrave/treuil pourra être amovible, la barre d'étrave étant reliée à la potence par l'intermédiaire d'une articulation (charnière ou rotule) de manière à pouvoir s'incliner d'au moins 30° par rapport à son axe en position de chargement, pour pouvoir être rabattue vers l'ensemble du chariot et gagner un peu plus de place par rapport à l'encombrement général du chariot. En position d'utilisation, la partie étrave/treuil est bloquée droite dans l'axe du chariot et est verrouillée à l'aide d'un axe ou vis traversant la partie support et la partie escamotable. Cet axe pourra être lui-même verrouillé au moyen d'un écrou ou d'une goupille. The stem / winch assembly may be removable, the stem bar being connected to the stem via a joint (hinge or ball joint) so as to be able to tilt at least 30 ° by relative to its axis in the loading position, to be able to be folded down towards the whole of the trolley and to gain a little more space compared to the general dimensions of the trolley. In the position of use, the bow / winch part is locked straight in the axis of the carriage and is locked using a pin or screw passing through the support part and the retractable part. This axis can itself be locked by means of a nut or a pin.
