Description

La présente invention concerne une structure pliante, utilisable comme passerelle et/ou échelle, et destinée plus particulièrement à une application nautique.The present invention relates to a folding structure, usable as a gangway and / or ladder, and intended more particularly for a nautical application.

Comme on le sait, des passerelles pliantes sont déjà connues et sont aptes à relier une embarcation à un point d'accostage pour permettre à l'utilisateur de descendre à terre ou de monter à bord.As is known, folding gangways are already known and are capable of connecting a boat to a docking point to allow the user to go ashore or to board.

I1 existe également des échelles pliantes entablées à proximité du bord du pont et suspendues à un palonnier qui en permet l'abaissement dans l'eau ou le levage dans le cas de non-utilisation. There are also folding ladders set up near the edge of the bridge and suspended from a lifting beam which allows it to be lowered into the water or lifted when not in use.

Les passerelles et échelles ci-dessus présentent toutefois des inconvénients importants, surtout de longueur, même en position repliée. En outre, les opérations de repliement se sont révélées trop laborieuses.The above gangways and ladders, however, have significant drawbacks, especially in length, even in the folded position. In addition, the folding operations proved to be too laborious.

L'objet technique de la présente invention est de proposer une structure pliante permettant d'obvier aux inconvénients ci-dessus mentionnés.The technical object of the present invention is to provide a folding structure allowing to overcome the drawbacks mentioned above.

A cet effet, la structure pliante, utilisable comme passerelle et/ou échelle en particulier dans le domaine nautique et comportant au moins deux tronçons reliés entre eux par des articulations, est remarquable, selon l'invention, en ce que lesdites articulations comprennent des éléments à plaque qui relient, de façon articulée, les extrémites contiguës desdits tronçons du côté de repliement de ceux-ci, et un levier entablé dans l'une desdites extrémités, du côté opposé à celui de repliement, ledit levier ayant un premier bras pourvu de moyens aptes à s'accrocher avec l'autre extrémité, et un second bras d'actionnement, lesdits élé- ments à plaque et ledit premier bras étant tels que, en position d'accrochage, lesdits tronçons sont bloqués en position d'alignement.To this end, the folding structure, usable as a gangway and / or ladder, in particular in the nautical field and comprising at least two sections linked together by articulations, is remarkable, according to the invention, in that said articulations comprise elements with plate which articulate, in an articulated manner, the contiguous extremities of said sections on the folding side thereof, and a lever set in one of said ends, on the side opposite that of folding, said lever having a first arm provided with means capable of hooking with the other end, and a second actuating arm, said plate elements and said first arm being such that, in the hooking position, said sections are locked in alignment position.

Avantageusement, lesdits moyens d'engagement sont constitués par un axe solidaire dudit premier bras, parallèlement à l'axe d'articulation dudit levier, et apte à engager une encoche dudit tronçon opposé à celui d'articulation du levier.Advantageously, said engagement means are constituted by an axis integral with said first arm, parallel to the axis of articulation of said lever, and capable of engaging a notch of said section opposite to that of articulation of the lever.

D'autres avantages et particularités de la présente invention apparaîtront ci-dessous en regard des figures du dessin annexé. Sur ces figures, des références identiques désignent des éléments semblables.Other advantages and features of the present invention will appear below with reference to the figures of the appended drawing. In these figures, identical references designate similar elements.

La figure 1 montre une vue en perspective d'une structure en position étendue, faisant fonction de passerelle et d'échelle.Figure 1 shows a perspective view of a structure in the extended position, acting as a gangway and ladder.

La figure 2 montre la structure de la figure 1 en position repliée.Figure 2 shows the structure of Figure 1 in the folded position.

Les figures 3, 4 et 5 montrent trois positions successives des moyens d'accrochage.Figures 3, 4 and 5 show three successive positions of the attachment means.

La figure 6 montre une articulation à une échelle agrandie.Figure 6 shows an articulation on an enlarged scale.

Comme le montrent ces figures, la structure est indiquée dans son ensemble par la référence numérique 1, et elle constitue une passerelle utilisable également comme échelle, par exemple pour descendre dans l'eau et sortir de l'eau.As these figures show, the structure is indicated as a whole by the reference numeral 1, and it constitutes a walkway which can also be used as a ladder, for example to descend into the water and to leave the water.

Une telle passerelle est composée de trois tronçons 2, 3 et 4, de longueur identique et articulés entre eux afin de pouvoir se replier en zigzag, avec les tronçons 2 et 4 agencés respectivement de part et d'autre du tronçon 3 intermédiaire. Such a gangway is made up of three sections 2, 3 and 4, of identical length and hinged together so as to be able to fold in a zigzag, with the sections 2 and 4 arranged respectively on either side of the intermediate section 3.

Chaque tronçon est composé de deux poutres ou montants 5, 6 parallèles, reliés entre eux par des traverses 7.Each section is composed of two parallel beams or uprights 5, 6, interconnected by crosspieces 7.

Chaque traverse comprend une partie 8 coplanaire au bord supérieur des montants et une partie 9 inclinée par rapport à la partie 8 et s'étendant entre les montants. Les extrémités opposées des parties 8 et 9 sont fixées, au moyen de vis 10, à des pattes Il agencées en saillie par rapport aux faces internes des montants.Each cross member comprises a part 8 coplanar with the upper edge of the uprights and a part 9 inclined with respect to the part 8 and extending between the uprights. The opposite ends of parts 8 and 9 are fixed, by means of screws 10, to lugs II arranged projecting relative to the internal faces of the uprights.

A l'extrémité du tronçon 2, opposée à celle articulée au tronçon 3, est assemblée, au moyen de broches 12, une plate-forme triangulaire 13 au sommet de laquelle est prévue une queue cylindrique 14 apte à s'engager, de façon articulée, dans un logement d'une embarcation, à proximité du bord du pont.At the end of the section 2, opposite that articulated to the section 3, is assembled, by means of pins 12, a triangular platform 13 at the top of which is provided a cylindrical tail 14 capable of engaging, in an articulated manner , in a boat accommodation, near the edge of the deck.

A l'autre extrémité du tronçon 4, sont supportés par l'intermédiaire d'une tige 15, deux galets rotatifs 16 qui font saillie, de façon périphérique, par dessous les montants.At the other end of the section 4, are supported by means of a rod 15, two rotary rollers 16 which project, peripherally, from below the uprights.

Quand la passerelle 1 est en position de liaison entre l'embarcation et le point d'accostage, les galets 16 s'appliquent sur le sol et les parties 8 des traverses 7 font office de marches pour les utilisateurs. Réciproquement, quand la passerelle est utilisée comme échelle, et prend alors une configuration oblique, les parties 9 des traverses sont utilisées comme marches, alors que les parties 8 constituent des nervures de rigidification inférieures.When the bridge 1 is in the position of connection between the boat and the docking point, the rollers 16 are applied to the ground and the parts 8 of the crosspieces 7 act as steps for the users. Conversely, when the gangway is used as a ladder, and then takes an oblique configuration, the parts 9 of the crosspieces are used as steps, while the parts 8 constitute lower stiffening ribs.

Conformément à l'invention, les articulations permettent aux tronçons de prendre une configuration alignée ou repliée.According to the invention, the joints allow the sections to take an aligned or folded configuration.

Dans la suite de la description, on se référera à l'un des quatre points d'articulation existant entre les tronçons 2, 3 et 4, lesdits points d'articulation étant identiques entre eux. In the following description, reference will be made to one of the four points of articulation existing between the sections 2, 3 and 4, said points of articulation being identical to each other.

Sur les figures 3 et 6, on remarque les montants 6 des deux tronçons 3 et 4 aux extrémités desquels sont associés deux embouts ou têtes 17, 18, chacun pourvu de deux fentes 19, 20 et 21, 22 coplanaires entre elles.In Figures 3 and 6, there are the amounts 6 of the two sections 3 and 4 at the ends of which are associated two tips or heads 17, 18, each provided with two slots 19, 20 and 21, 22 coplanar therebetween.

Dans les fentes 20, 21 est articulée, par l'intermédiaire de tourillons 23, 24 ou analogues, un élément en forme de plaque 25 qui maintient relié, de façon articulée, les tronçons. Dans la tête 18 est reçu, par l'intermédiaire d'un axe 26, un levier comprenant un premier bras 27 sous forme de plaque oscillante dans la fente 22, et un second bras 28, externe à la tête 18 et relié à un levier analogue (disposé de façon symétrique sur l'autre côté de la passerelle, à l'intérieur des montants 5) par une barre 29. La plaque 27 est pourvue d'un axe 30 faisant saillie par rapport aux deux faces de la plaque, et susceptible de s'engager dans une encoche 31 qui coupe la fente 19. L'encoche 31 s'étend suivant un arc de cercle dont le rayon est égal à la distance entre les axes 26 et 30.In the slots 20, 21 is articulated, by means of pins 23, 24 or the like, a plate-shaped element 25 which keeps the sections connected, in an articulated manner. In the head 18 is received, via a pin 26, a lever comprising a first arm 27 in the form of an oscillating plate in the slot 22, and a second arm 28, external to the head 18 and connected to a lever similar (arranged symmetrically on the other side of the gangway, inside the uprights 5) by a bar 29. The plate 27 is provided with a pin 30 projecting relative to the two faces of the plate, and capable of engaging in a notch 31 which cuts the slot 19. The notch 31 extends in an arc of a circle whose radius is equal to the distance between the axes 26 and 30.

Quand la passerelle est en position opérationnelle alignée, par effet d'un ressort de traction 32 interposé entre le second bras 28 du levier et la patte 11, l'axe 30 se trouve engagé dans l'encoche 31 de façon que les tronçons, en coopération avec les plaques 25, soient bloqués linéairement, avec les têtes 17, 18 en vis-à-vis l'une de l'autre (figure 3). On remarque que, sur la passerelle illustrée sur la figure 1, les plaques 25 qui unissent les tronçons 3, 4 sont soumises à la traction aussi bien que les bras 27 qui relient les tronçons 2 et 3.When the bridge is in the aligned operational position, by the effect of a tension spring 32 interposed between the second arm 28 of the lever and the lug 11, the axis 30 is engaged in the notch 31 so that the sections, in cooperation with the plates 25, are blocked linearly, with the heads 17, 18 facing each other (Figure 3). It is noted that, on the gangway illustrated in FIG. 1, the plates 25 which unite the sections 3, 4 are subjected to traction as well as the arms 27 which connect the sections 2 and 3.

Pour mettre la passerelle en position repliée, on actionne la barre 29 qui, agissant sur les bras 28 du levier, provoque le pivotement des bras 27 et, ensuite, le désengagement des axes 30 des encoches 31 (figures 4 et 5). To put the gangway in the folded position, the bar 29 is actuated which, acting on the arms 28 of the lever, causes the arms 27 to pivot and then disengage the axes 30 from the notches 31 (FIGS. 4 and 5).

On comprend donc que l'invention décrite atteint parfaitement les buts recherchés.It is therefore understood that the invention described perfectly achieves the desired goals.

En particulier, les articulations entre les tronçons permettent une réduction considérable des dimensions longitudinales et, donc, un arrimage plus facile de la passerelle dans le coqueron d'une embarcation ou bien le repliement de ladite passerelle contre le balcon arrière auquel elle est fixée.In particular, the articulations between the sections allow a considerable reduction of the longitudinal dimensions and, therefore, an easier securing of the gangway in the locker of a boat or else the folding of said gangway against the rear balcony to which it is fixed.

Dans la pratique, la réalisation de l'invention est susceptible de nombreuses modifications et variantes. Par exemple, à la tige 15 peut être accrochée, de façon articulée, une échelle auxiliaire 33 qui permet une descente perpendiculaire dans l'eau, indépendamment de l'inclinaison de la passerelle. En outre, aux montants 5, 6 du tronçon 2 peuvent être fixés des appuis réglables qui, s'appliquant sur le tableau de l'embarcation, empêchent les montants de glisser sur lui, en l'endommageant. In practice, the implementation of the invention is susceptible of numerous modifications and variants. For example, to the rod 15 can be hung, in an articulated manner, an auxiliary ladder 33 which allows a perpendicular descent into the water, regardless of the inclination of the bridge. In addition, to the uprights 5, 6 of the section 2 can be fixed adjustable supports which, being applied to the table of the boat, prevent the uprights from sliding on it, damaging it.
