Description

La présente invention concerne un système de déploiement et de dépose, à partir d'un véhicule tel qu'un engin blindé du génie, d'une travure de franchissement d'un obstacle formé par exemple par une brèche pouvant éventuellement être située dans une zone contaminée NBC (Nucléaire Bactériologique Chimique).The present invention relates to a system for deploying and removing, from a vehicle such as an armored engineering vehicle, a span for crossing an obstacle formed for example by a breach which may possibly be located in an area contaminated NBC (Chemical Bacteriological Nuclear).

On connaît des systèmes de déploiement de telles travures verticalement pivotantes et comprenant au moins deux éléments principaux successifs, un élément extrême interne et un élément extrême externe rabattable vers le bas contre l'élément extrême interne le long de celui-ci et monté articulé l'un par rapport à l'autre vers leurs extrémités adjacentes par un axe d'articulation sensiblement perpendiculaire à l'axe longitudinal de la travure qui est fixée en au moins un point de l'un des deux éléments extrêmes interne et externe à au moins un câble de manoeuvre s'enroulant par exemple sur au moins un treuil placé sur le véhicule (voir, par exemple, US-A 2 556 175 "SOLDAT UND TECHNIK", vol. 17, no. 7, 1974, pages 360-372).Deployment systems are known for such vertically pivoting spans and comprising at least two successive main elements, an internal extreme element and an external extreme element which can be folded down against the internal extreme element along the latter and hinged mounted. one relative to the other towards their adjacent ends by an articulation axis substantially perpendicular to the longitudinal axis of the span which is fixed at at least one point of one of the two internal and external extreme elements to at least one control cable winding, for example, on at least one winch placed on the vehicle (see, for example, US-A 2,556,175 "SOLDIER UND TECHNIK", vol. 17, no. 7, 1974, pages 360-372) .

Cependant, ces systèmes connus comprennent au moins un moyen de commande constitué par exemple par un vérin pour assurer la rotation de l'élément extrême externe par rapport à l'élément extrême interne autour de l'axe d'articulation. De tels moyens de commande ont pour inconvénient d'alourdir la travure et surtout de consommer beaucoup d'énergie additionnelle.However, these known systems comprise at least one control means constituted for example by a jack for ensuring the rotation of the outer extreme element relative to the inner extreme element around the axis of articulation. Such control means have the disadvantage of weighing down the span and above all consuming a lot of additional energy.

La présente invention a pour but d'éliminer les inconvénients ci-dessus des systèmes connus en proposant un système de déploiement et de dépose d'une travure ne nécessitant aucun moyen de commande ni de source d'énergie additionnels.The object of the present invention is to eliminate the above drawbacks of known systems by proposing a system for deploying and depositing a span requiring no additional control means or energy source.

Pour cela, le système de déploiement et de dépose selon l'invention est caractérisé en ce qu'à une position de transport de la travure sur le véhicule, l'élément extrême externe est supporté et maintenu de façon pivotante à son extrémité libre par un dispositif de support mobile du véhicule occupant une position relevée tandis que l'élément interne repose le long de l'élément extrême externe ; en ce que la travure est relevable par enroulement du câble de manoeuvre sur le treuil en une position où l'élément extrême interne est supporté de façon pivotante à son extrémité libre par le dispositif de support avec libération concomitante de l'extrémité libre de l'élément extrême externe du dispositif de support ; en ce que le dispositif de support est ensuite abaissé vers une position d'appui sur le sol pour provoquer un écartement de l'élément extrême externe de l'élément extrême interne et permettre ainsi le déploiement de la travure ; et en ce que le câble de manoeuvre est déroulé du treuil pour abaisser et déposer la travure au-dessus de la brèche.For this, the deployment and removal system according to the invention is characterized in that in a position for transporting the span on the vehicle, the external extreme element is supported and pivotally held at its free end by a mobile support device for the vehicle occupying a raised position while the internal element rests along the external extreme element; in that the span is liftable by winding the operating cable on the winch in a position where the inner end element is pivotally supported at its free end by the support device with concomitant release from the free end of the external end element of the support device; in that the support device is then lowered to a support position on the ground to cause a separation of the outer extreme element from the inner extreme element and thus allow the deployment of the span; and in that the operating cable is unwound from the winch to lower and deposit the span above the breach.

Selon une caractéristique de l'invention, l'extrémité libre de l'élément extrême interne est libérée du dispositif de support par recul du véhicule par rapport à la travure.According to a characteristic of the invention, the free end of the internal end element is released from the support device by the vehicle moving back relative to the span.

Selon une autre caractéristique de l'invention, le dispositif de support comprend au moins un organe de verrouillage de l'extrémité libre de l'élément extrême externe audit dispositif et déverrouillé lorsque l'extrémité libre de l'élément extrême interne vient en appui sur le dispositif de support à la position relevée de la travure.According to another characteristic of the invention, the support device comprises at least one member for locking the free end of the end element external to said device and unlocked when the free end of the internal end element bears on the support device in the raised position of the span.

Selon toujours une autre caractéristique de l'invention, l'organe de verrouillage comprend une partie formant crochet de retenue au dispositif de support d'un axe de l'extrémité libre de l'élément extrême externe, disposé transversalement à l'axe longitudinal de la travure, et pouvant pivoter par rapport au dispositif de support dans la direction de déverrouillage à l'encontre de la force de rappel d'un organe élastique tel qu'un ressort de traction et, solidaire de la partie formant crochet, une partie formant bras de pivotement de la partie formant crochet actionné par un axe de l'extrémité libre de l'élément extrême interne disposé transversalement à l'axe longitudinal de la travure à la position relevée de la travure.Still according to another characteristic of the invention, the locking member comprises a part forming a hook retaining to the device for supporting an axis of the free end of the external extreme element, arranged transversely to the longitudinal axis of the span, and being able to pivot relative to the support device in the unlocking direction against the return force of an elastic member such as a tension spring and, integral with the hook part, a part forming pivot arm of the hook part actuated by an axis of the free end of the internal end element disposed transversely to the longitudinal axis of the span in the raised position of the span.

Selon encore une autre caractéristique de l'invention, le dispositif de support comprend de plus au moins deux plaques parallèles perpendiculaires au sol solidaires d'un élément de support du dispositif et une pièce d'appui des axes d'extrémité respectifs des deux éléments extrêmes interne et externe, montée pivotante entre les deux plaques et pouvant coopérer alternativement avec deux butées solidaires des plaques limitant le débattement pivotant de la pièce d'appui à deux positions angulaires extrêmes, l'une d'appui de l'axe d'extrémité de l'élément extrême externe à la position de transport de la travure et de l'axe d'extrémité de l'élément extrême interne aux positions relevée et de déploiement de la travure, et l'autre de dégagement de l'axe d'extrémité de l'élément extrême interne lors du recul du véhicule.According to yet another characteristic of the invention, the support device further comprises at least two parallel plates perpendicular to the ground secured to a support element of the device and a support piece of the respective end axes of the two extreme elements internal and external, pivotally mounted between the two plates and able to cooperate alternately with two stops integral with the plates limiting the pivoting movement of the support piece at two extreme angular positions, one supporting the end axis of the extreme external element in the position for transporting the span and the end axis of the internal extreme element in the raised and deploying positions of the span, and the other for releasing the end axis of the internal extreme element when the vehicle is reversing.

Selon encore une autre caractéristique de l'invention, la pièce d'appui comprend deux évidements à fond arrondi d'appui respectivement des deux axes d'extrémité des éléments extrêmes interne et externe et la partie formant crochet de l'organe de verrouillage coopère avec l'évidement d'appui de l'axe d'extrémité de l'élément extrême externe et un bord avant de chacune des plaques parallèles pour verrouiller ledit axe à la position de transport de la travure.According to yet another characteristic of the invention, the support piece comprises two recesses with rounded support bottom respectively of the two end axes of the inner and outer end elements and the hook part of the locking member cooperates with the bearing recess of the end axis of the external end element and a front edge of each of the parallel plates to lock said axis in the position of transport of the span.

Selon toujours une autre caractéristique de l'invention, l'organe de verrouillage, réalisé en une seule pièce avec le bras de pivotement opposé à la partie formant crochet, est monté pivotant dans la pièce d'appui, lequel bras de pivotement fait saillie dans l'évidement d'appui de l'axe d'extrémité de l'élément extrême interne à la position de transport de la travure.Still according to another characteristic of the invention, the locking member, produced in one piece with the pivot arm opposite the hook portion, is pivotally mounted in the support piece, which pivot arm projects in the support recess of the end axis of the internal end element in the position for transporting the span.

En se reportant aux figures 1 A à 1 H, la référence 1 désigne un véhicule notamment un engin blindé du génie comprenant un dispositif de support 2 d'une travure 3 fixée en au moins un point 4 à au moins un câble de manoeuvre 5 s'enroulant par exemple sur au moins un treuil (non représenté) placé sur le véhicule 1. Le câble de manoeuvre 5 est relié au treuil en passant par un palonnier à poulies 6 monté articulé à un bras 7 du véhicule 1, lequel bras est maintenu sur le véhicule par un haubanage 8.Referring to FIGS. 1 A to 1 H, the reference 1 designates a vehicle in particular an armored engineering vehicle comprising a support device 2 of a span 3 fixed at at least one point 4 to at least one operating cable 5 s 'winding for example on at least one winch (not shown) placed on the vehicle 1. The operating cable 5 is connected to the winch via a pulley spreader 6 mounted articulated to an arm 7 of the vehicle 1, which arm is held on the vehicle by a guy line 8.

Le dispositif de support 2 comprend un élément de support proprement dit 2a constitué dans le cas présent par une partie formant lame creuse analogue à celle d'un bouteur. Le dispositif de support 2 est monté mobile par rapport au véhicule 1 entre une position relevée représentée en pointillé en figure 4 et une position abaissée sur le sol. Pour cela, un bras principal 1 a est monté pivotant à l'une de ses extrémités sur le véhicule 1 et est solidaire à son autre extrémité de la partie inférieure du dispositif de support 2. Le bras principal 1a est solidaire d'un bras de renvoi 1b, dont l'extrémité libre est relié à l'extrémité libre d'une tige d'un organe de commande constitué par exemple par un vérin hydraulique 1 placé sur le véhicule. Un bras de renforcement 1 d est disposé entre la partie médiane du bras principal 1a et la partie supérieure du dispositif de support 2. Un tel mécanisme de relevage et d'abaissement d'une lame étant déjà connu en soi, il n'a pas à être décrit plus en détail.The support device 2 comprises a support element proper 2a constituted in the present case by a part forming a hollow blade similar to that of a bulldozer. The support device 2 is mounted movable relative to the vehicle 1 between a raised position shown in dotted lines in FIG. 4 and a lowered position on the ground. For this, a main arm 1a is pivotally mounted at one of its ends on the vehicle 1 and is secured at its other end to the lower part of the support device 2. The main arm 1a is secured to a reference 1b, the free end of which is connected to the free end of a rod of a control member constituted for example by a hydraulic cylinder 1 placed on the vehicle. A reinforcing arm 1 d is disposed between the middle part of the main arm 1a and the upper part of the support device 2. Since such a mechanism for raising and lowering a blade is already known per se, it does not have to be described in more detail.

La travure 3 comprend au moins deux éléments principaux successifs un élément extrême interne 3a et un élément extrême externe 3b, montés articulés l'un par rapport à l'autre vers leurs extrémités adjacentes par un axe d'articulation 3c sensiblement perpendiculaire à l'axe longitudinal X-X' de la travure (voir figure 8).The span 3 comprises at least two successive main elements, an internal extreme element 3a and an external extreme element 3b, mounted articulated with respect to each other towards their adjacent ends by an articulation axis 3c substantially perpendicular to the axis. longitudinal XX 'of the span (see figure 8).

Le principe de fonctionnement du système de l'invention va être décrit en référence aux figures 1 A à 1H.The operating principle of the system of the invention will be described with reference to Figures 1 A to 1H.

Le câble de manoeuvre 5, rattaché dans le cas présent à l'élément extrême externe 3b de la travure 3 en cheminant sur cet élément comme il sera décrit plus en détail ultérieurement et sur les poulies du palonnier 6 fixées sur le bras 7 du véhicule 1, maintient la travure 3 sur le dispositif de support 2 en configuration de transport de la travure représentée en figure 1A. A cette position de transport de la travure, l'élément extrême externe 3b est supporté et maintenu de façon pivotante à son extrémité libre par le dispositif de support 2 occupant la position relevée tandis que l'élément extrême interne 3a repose sur l'élément extrême externe 3b le long de celui-ci par l'intermédiaire d'un dispositif formant tampon représenté schématiquement par la référence 3d et solidaire par exemple de l'élément 3b. Il est à noter que l'extrémité libre de l'élément 3a à la position de transport est totalement libérée, c'est-à-dire que cet élément n'est pas du tout en appui sur le dispositif de support 2. De plus, un organe de verrouillage, qui sera décrit plus en détail ultérieurement , monté sur le dispositif de support 2, maintient l'extrémité libre de l'élément 3b au dispositif de support 2. La travure 3 est ainsi transportée par le véhicule 1 qui se positionne sur l'aire de lancement retenue représentée dans le cas présent par une brèche B.The operating cable 5, attached in the present case to the outer extreme element 3b of the span 3 by traveling on this element as will be described in more detail later and on the pulleys of the spreader 6 fixed on the arm 7 of the vehicle 1 , maintains the span 3 on the support device 2 in the transport configuration of the span shown in FIG. 1A. In this position for transporting the span, the external extreme element 3b is supported and pivotally held at its free end by the support device 2 occupying the raised position while the internal extreme element 3a rests on the extreme element external 3b along the latter via a buffer device represented schematically by the reference 3d and secured for example to the element 3b. It should be noted that the free end of the element 3a in the transport position is completely released, that is to say that this element is not at all supported on the support device 2. In addition , a locking member, which will be described in more detail later, mounted on the support device 2, maintains the free end of the element 3b to the support device 2. The span 3 is thus transported by the vehicle 1 which is positions on the selected launching area represented in this case by a breach B.

Une fois le véhicule positionné, la travure 3 est relevée par enroulement du câble de manoeuvre 5 sur le treuil du véhicule jusqu'à la position représentée en figure 1 B, proche de la position verticale, et à laquelle l'élément extrême interne 3a est supporté de façon pivotante à son extrémité libre par le dispositif de support 2 avec libération concomitante de l'extrémité libre de l'élément extrême externe 3b du dispositif de support. A la position relevée de la figure 1 B, le dispositif de support 2 occupe toujours la position relevée de la figure 1A. On comprend que le relevage de la travure permet de passer d'un portage de l'élément extrême externe 3b à l'élément extrême interne 3a, le changement de point d'appui de la travure sur le support 2 permettant de libérer la partie inférieure de l'élément extrême externe 3b en actionnant l'organe de verrouillage de l'extrémité libre de cet élément comme il sera décrit ultérieurement. A la position relevée de la figure 1 B, le centre de gravité de la travure est pratiquement centré à l'extrémité d'appui de l'élément extrême interne sur le dispositif de sorte que l'élément extrême externe est rabattu contre l'élément extrême interne.Once the vehicle is positioned, the span 3 is raised by winding the operating cable 5 on the winch of the vehicle to the position shown in FIG. 1B, close to the vertical position, and at which the internal end element 3a is pivotally supported at its free end by the support device 2 with concomitant release of the free end of the external end element 3b of the support device. In the raised position of FIG. 1B, the support device 2 always occupies the raised position of FIG. 1A. It is understood that the lifting of the span makes it possible to pass from a portage of the external extreme element 3b to the internal extreme element 3a, the change of fulcrum of the span on the support 2 making it possible to release the lower part of the external end element 3b by actuating the locking member of the free end of this element as will be described later. In the raised position of FIG. 1B, the center of gravity of the span is practically centered at the bearing end of the internal extreme element on the device so that the external extreme element is folded against the element extreme internal.

Le dispositif de support 2 est ensuite abaissé comme indiqué par la flèche A de façon à abaisser le point d'appui de l'élément extrême interne 3a sur le dispositif 2 et écarter l'élément extrême externe 3b de l'élément extrême interne 3a et permettre ainsi le déploiement de la travure comme représenté en figure 1 E. Durant l'abaissement du dispositif de support 2, le câble de manoeuvre 5 chemine sur un prolongement latéral 3b1 de l'élément 3b de sorte que celui-ci fasse office de bras de levier autour de l'axe d'articulation 3c pour faciliter l'écartement de l'élément extrême externe 3b de l'élément extrême interne 3a. Il est à noter que de la position relevée de la travure représentée en figure 1 B à la position déployée de celle-ci représentée en figure 1 E, la longueur de câble de manoeuvre 5 reste constante de sorte que seul l'abaissement du dispositif de support 2, compte tenu du cheminement du câble sur le prolongement 3b1 et de son point d'attache 4, assure le déploiement de la travure 3.The support device 2 is then lowered as indicated by the arrow A so as to lower the fulcrum of the internal end element 3a on the device 2 and move the external end element 3b away from the internal end element 3a and allow the deployment of the span as shown in Figure 1 E. During the lowering of the support device 2, the operating cable 5 runs on a lateral extension 3b1 of the element 3b so that it acts as an arm lever around the hinge axis 3c to facilitate the spacing of the outer end member 3b from the inner end member 3a. It should be noted that from the raised position of the span shown in FIG. 1 B to the extended position of the latter shown in FIG. 1 E, the length of the operating cable 5 remains constant so that only the lowering of the device sup port 2, taking into account the cable routing on the extension 3b1 and its attachment point 4, ensures the deployment of the span 3.

A partir de la position de déploiement de la travure représentée en figure 1 E et à laquelle le dispositif de support 2 repose sur le sol, le câble de manoeuvre 5 est déroulé du treuil pour abaisser et déposer la travure 3 au-dessus de la brèche B comme représenté en figure 1 F.From the position of deployment of the span shown in FIG. 1 E and at which the support device 2 rests on the ground, the operating cable 5 is unwound from the winch to lower and deposit the span 3 above the breach B as shown in Figure 1 F.

Une fois la travure déposée au-dessus de la brèche, le câble de manoeuvre 5 est déroulé davantage du treuil pour lui donner du mou et le libérer automatiquement de son point d'attache à l'élément extrême externe 3b à la manière qui sera décrite ultérieurement (voir figure 1 G).Once the span deposited above the breach, the operating cable 5 is unwound further from the winch to give it slack and automatically release it from its point of attachment to the external extreme element 3b in the manner which will be described later (see Figure 1 G).

Le véhicule 1 est ensuite déplacé en reculant par rapport à la travure 3 comme indiqué par la flèche R en figure 1 H pour libérer l'extrémité de l'élément extrême interne 3a de la travure du dispositif 2 et dégager le câble de manoeuvre 5 de celle-ci.The vehicle 1 is then moved backward with respect to the span 3 as indicated by the arrow R in FIG. 1H to release the end of the internal extreme element 3a from the span of the device 2 and release the operating cable 5 from this one.

Après utilisation de la travure, la travure est repliée comme suit.After using the span, the span is folded as follows.

Le véhicule 1 se rapproche de la travure avec le dispositif de support 2 en position abaissée de manière que celle-ci soulève l'extrémité de l'élément extrême interne 3a et la positionne à son point d'appui sur le dispositif 2. Le câble de manoeuvre 5 est ensuite fixé à un point d'ancrage ou d'attache de l'élément extrême interne 3a situé à proximité de son extrémité opposée à son point d'appui sur le dispositif 2. Le câble 5 est alors enroulé sur le treuil de manière à soulever la travure vers la position approximativement verticale représentée en figure 1 B. Durant cette phase de relevage de la travure, l'élément extrême externe 3b se rabat vers et contre l'élément extrême interne le long de celui-ci et le dispositif de support 2 passe de la position abaissée à la position relevée. A la position relevée de la figure 1 B, le centre de gravité de la travure est centré pratiquement a l'extrémité d'appui de l'élément extrême interne sur le dispositif 2 de sorte que l'élément extrême externe 3b se trouve bien rabattu contre l'élément extrême interne. Le câble de manoeuvre 5 est ensuite déroulé du treuil pour amener la travure à une position angulaire correspondant à celle représentée en figure 1A (par exemple d'environ 30° par rapport au sol). Bien entendu, à cette position, l'élément extrême externe 3b est verrouillé et maintenu sur le dispositif de support 2 et l'autre élément 3a repose sur l'élément 3b. Une remorque (non représentée) est ensuite rapprochée de la travure dans son axe longitudinal. Le câble de manoeuvre 5 est de nouveau déroulé pour amener l'extrémité de la travure opposée à son extrémité en appui sur le dispositif 2 sur la remorque suivant une configuration telle que le point d'appui de l'élément extrême interne sur le dispositif 2 soit à une hauteur quelle que peu supérieure à celle de l'extrémité opposée de la travure. Le dispositif de support 2 est ensuite abaissé de manière à poser complètement la travure sur la remorque et l'organe de déverrouillage est actionné manuellement pour libérer l'extrémité libre de l'élément extrême interne 3b du dispositif 2.The vehicle 1 approaches the span with the support device 2 in the lowered position so that it raises the end of the internal extreme element 3a and positions it at its point of support on the device 2. The cable 5 is then fixed to an anchor or attachment point of the internal end element 3a located near its end opposite to its point of support on the device 2. The cable 5 is then wound on the winch so as to raise the span towards the approximately vertical position shown in FIG. 1 B. During this phase of raising the span, the outer extreme element 3b folds down towards and against the inner extreme element along the latter and the support device 2 goes from the lowered position to the raised position. In the raised position of FIG. 1B, the center of gravity of the span is practically centered at the bearing end of the internal extreme element on the device 2 so that the external extreme element 3b is well folded down against the inner extreme element. The operating cable 5 is then unwound from the winch to bring the span to an angular position corresponding to that shown in FIG. 1A (for example around 30 ° relative to the ground). Of course, in this position, the external end element 3b is locked and held on the support device 2 and the other element 3a rests on the element 3b. A trailer (not shown) is then brought closer to the span in its longitudinal axis. The operating cable 5 is again unwound to bring the end of the span opposite its end in abutment on the device 2 on the trailer in a configuration such as the fulcrum of the internal end element on the device 2 either at a height somewhat higher than that of the opposite end of the span. The support device 2 is then lowered so as to place the span completely on the trailer and the unlocking member is actuated manually to release the free end of the internal end element 3b of the device 2.

La reprise de la travure de la remorque sur le dispositif de support 2 est accomplie en approchant la remorque du dispositif de manière que l'extrémité libre de l'élément extrême externe 3b soit amenée en regard de l'organe de verrouillage du dispositif et verrouillée manuellement dans celui-ci. Le câble de manoeuvre 5 enroulé partiellement sur le prolongement 3b1 est fixé au point de fixation 4 est ensuite enroulé sur le treuil de manière à soulever la travure autour de son point d'articulation sur le dispositif 2 et l'amener à la position de transport représentée en figure 1A. La travure se trouve alors prête pour un nouveau processus de déploiement sur une autre brèche.The recovery of the span of the trailer on the support device 2 is accomplished by approaching the trailer of the device so that the free end of the external end element 3b is brought opposite the locking member of the device and locked manually in this one. The operating cable 5 partially wound on the extension 3b1 is fixed to the fixing point 4 is then wound on the winch so as to lift the span around its point of articulation on the device 2 and bring it to the transport position shown in Figure 1A. The span is then ready for a new deployment process on another breach.

En se reportant aux figures 2, 3 et 8 il va être décrit en détail la structure et le fonctionnement du point de fixation de l'extrémité du câble 5 à l'élément extrême externe 3b permettant un décrochage automatique du câble à la position déployée de la travure. Le point de fixation 4 est constitué d'une plaque de support 4a d'une pièce formant crochet 4b et pouvant coopérer alternativement avec deux butées 9 et 10 solidaires du prolongement 3b1 de l'élément extrême externe pour limiter le débattement pivotant de la plaque 4a autour d'un axe 4a1 solidaire du prolongement 3b1 à deux positions angulaires extrêmes respectivement d'accrochage du câble de manoeuvre 5 comme représenté en figure 2 et de décrochage du câble comme représenté en figure 3. Un organe élastique de rappel tel que par exemple un ressort de traction 11 est relié à l'une de ses extrémités à la plaque de support 4a et à son autre extrémité au prolongement 3b1. Ce ressort tend à ramener la plaque de support 4a contre la butée 10. La pièce à crochet 4b est montée pivotante autour d'un axe 4b1 solidaire de la plaque de support 4a et comporte une patte 4b2 faisant saillie à laquelle est reliée l'extrémité d'un organe de rappel élastique 12 constitué également par exemple par un ressort, dont l'autre extrémité est reliée au point commun de fixation de l'extrémité du ressort 11 sur la plaque 4a. Le ressort 12 tend à rappeler la pièce à crochet 4b dans le sens des aiguilles d'une montre par rapport à la plaque 4a. Le prolongement formant bras latéral de levier 3b1 de l'élément extrême externe 3b est solidaire latéralement de celui-ci, au voisinage de son axe d'articulation avec l'élément 3a comme cela est clairement représenté en figure 8, et s'étend sensiblement parallèlement à l'axe longitudinal de l'élément 3b au-delà de l'axe 3c. L'ensemble constitué par la plaque de support 4a et la pièce formant crochet 4b est logé dans le bras 3b1 au voisinage de l'extrémité de l'élément extrême externe 3b proche de l'axe 3c. Le bras 3b1 comporte à son extrémité libre, de forme arrondie, un chemin de guidage du câble de manoeuvre 5. Ce dernier est relié au crochet de la pièce 4b par l'intermédiaire d'une chape 13.Referring to Figures 2, 3 and 8 there will be described in detail the structure and operation of the point of attachment of the end of the cable 5 to the outer end member 3b allowing automatic release of the cable in the deployed position of the span. The fixing point 4 consists of a support plate 4a of a piece forming a hook 4b and which can cooperate alternately with two stops 9 and 10 integral with the extension 3b1 of the external end element to limit the pivoting movement of the plate 4a around an axis 4a1 integral with the extension 3b1 at two extreme angular positions respectively for hooking the operating cable 5 as shown in FIG. 2 and for unhooking the cable as shown in FIG. 3. An elastic return member such as for example a tension spring 11 is connected at one of its ends to the support plate 4a and at its other end to the extension 3b1. This spring tends to bring the support plate 4a against the stop 10. The hook piece 4b is pivotally mounted about an axis 4b1 secured to the support plate 4a and has a tab 4b2 projecting to which the end is connected an elastic return member 12 also constituted for example by a spring, the other end of which is connected to the common point of attachment of the end of the spring 11 on the plate 4a. The spring 12 tends to return the hook piece 4b clockwise relative to the plate 4a. The extension forming the lateral lever arm 3b1 of the external extreme element 3b is laterally integral with the latter, in the vicinity of its axis of articulation with the element 3a as is clearly shown in FIG. 8, and extends substantially parallel to the longitudinal axis of the element 3b beyond the axis 3c. The assembly constituted by the support plate 4a and the hook-forming part 4b is housed in the arm 3b1 in the vicinity of the end of the external extreme element 3b close to the axis 3c. The arm 3b1 has at its free end, of rounded shape, a guide path for the operating cable 5. The latter is connected to the hook of the part 4b by means of a yoke 13.

L'élément extrême interne 3a comprend également, solidaire latéralement de celui-ci, et au voisinage de l'axe 3c,un prolongement formant bras latéral de levier 3a1 identique au bras 3b1 et lequel prolongement 3a1 comporte un point de fixation 4 d'une structure et d'un fonctionnement identiques au point de fixation 4 décrit en figure 2. Le bras 3a1 s'étend sensiblement parallèlement à l'axe longitudinal dudit élément au-delà de l'axe 3c.The internal end element 3a also comprises, laterally integral with the latter, and in the vicinity of the axis 3c, an extension forming a lateral lever arm 3a1 identical to the arm 3b1 and which extension 3a1 comprises a fixing point 4 of a structure and operation identical to the attachment point 4 described in Figure 2. The arm 3a1 extends substantially parallel to the longitudinal axis of said element beyond the axis 3c.

A la position de transport de la travure représentée en figure 2, le câble 5 chemine sur le pourtour extrême du bras 3b1 et exerce une traction sur la pièce à crochet 4b par l'intermédiaire de la chape 13. La pièce à crochet 4b, contre l'action de rappel du ressort 12, vient en appui contre une partie correspondante de la plaque de support 4a, laquelle est en appui forcé contre la butée 9 à l'encontre de l'action de rappel du ressort 11. La position du point de fixation 4 par rapport au prolongement 3b1 représentée en figure 2 est maintenue durant les phases de relevage et de déploiement de la travure. Lorsque la travure est posée sur la brèche B comme représenté en figure 1G, le treuil est actionné de manière à donner du mou au câble 5. Dans cette condition, comme représenté en figure 3, le ressort 11 rappelle la plaque de support 4a contre la butée 10 et le ressort 12 rappelle la pièce à crochet 4b dans le sens des aiguilles d'une montre par rapport à la plaque 4a vers une position où la chape 13 du câble 5 se dégage par gravité du crochet de la pièce 4b. Le débattement pivotant de la pièce 4b par rapport à la plaque 4a est limité par un pied 4b3 venant en appui sur une partie correspondante de la plaque 4a.In the position for transporting the span shown in FIG. 2, the cable 5 runs over the extreme periphery of the arm 3b1 and exerts traction on the hook piece 4b by means of the yoke 13. The hook piece 4b, against the return action of the spring 12 comes to bear against a corresponding part of the support plate 4a, which is in forced support against the stop 9 against the return action of the spring 11. The position of the point fixing 4 relative to the extension 3b1 shown in Figure 2 is maintained during the lifting and deployment phases of the span. When the span is placed on the breach B as shown in FIG. 1G, the winch is actuated so as to give slack to the cable 5. In this condition, as shown in FIG. 3, the spring 11 recalls the support plate 4a against the stop 10 and spring 12 recalls the hook piece 4b clockwise relative to the plate 4a to a position where the yoke 13 of the cable 5 is released by gravity from the hook of the piece 4b. The pivoting movement of the part 4b relative to the plate 4a is limited by a foot 4b3 coming to bear on a corresponding part of the plate 4a.

La figure 8 représente de plus un dispositif amortisseur 14 constitué par exemple par un vérin monté suivant l'axe X-X' et dont le corps 14a est solidaire de l'élément extrême externe 3b et la tige 14b, passant au-dessus de l'axe 3c, est solidaire à son extrémité libre de l'élément extrême interne 3a. Le dispositif amortisseur 14 a pour effet de temporiser l'effet d'accélération du mouvement d'ouverture de la travure 3 créée avant le déploiement complet de la travure.FIG. 8 also represents a damping device 14 constituted for example by a jack mounted along the axis XX 'and the body 14a of which is integral with the external end element 3b and the rod 14b, passing above the axis 3c, is integral at its free end with the internal end element 3a. The damping device 14 has the effect of delaying the effect of acceleration of the opening movement of the span 3 created before the complete deployment of the span.

Le dispositif de support 2 va être maintenant décrit en détail en référence aux figures 5-7 et 9.The support device 2 will now be described in detail with reference to FIGS. 5-7 and 9.

Ce dispositif comprend au moins deux plaques parallèles 2b, solidaires de la lame 2a et situées respectivement dans un plan transversal à la lame 2a et donc perpendiculaire au sol. Chaque plaque 2b a une partie de forme arquée conjuguée à la partie creuse de la lame 2a pour venir en appui sur celle-ci et comporte à son extrémité supérieure une partie recourbée 2b1 enserrant la partie supérieure de la lame 2a. Un organe de fixation, tel que par exemple une vis symbolisée par un trait mixte, peut être prévu à la partie supérieure de la lame 2a pour parfaire la fixation de la plaque 2b à la lame 2a. Les plaques 2b comprennent de plus respectivement deux bords avant 2b2 reliés au niveau de la partie inférieure des plaques à une partie formant nez 2b3 pour former un chemin de guidage pour l'extrémité de l'élément extrême interne 3b de la travure comme il sera expliqué plus loin.This device comprises at least two parallel plates 2b, integral with the blade 2a and situated respectively in a plane transverse to the blade 2a and therefore perpendicular to the ground. Each plate 2b has an arcuate part conjugated to the hollow part of the blade 2a to come to bear on the latter and comprises at its upper end a curved part 2b1 enclosing the upper part of the blade 2a. A fixing member, such as for example a screw symbolized by a dashed line, can be provided at the upper part of the blade 2a to perfect the fixing of the plate 2b to the blade 2a. The plates 2b further comprise respectively two front edges 2b2 connected at the level of the lower part of the plates to a part forming a nose 2b3 to form a guide path for the end of the internal end element 3b of the span as will be explained further.

Le dispositif de support 2 comprend de plus une pièce d'appui 2c des extrémités respectives des éléments extrêmes 3a et 3b, montée pivotante entre les deux plaques 2b autour d'un axe 2c1 disposé transversalement entre les deux plaques 2b et pouvant coopérer alternativement avec deux butées 15 et 16 solidaires des plaques limitant le débattement pivotant de la pièce d'appui à deux positions angulaires extrêmes, l'une d'appui de l'extrémité de l'élément extrême externe 3b à la position de transport de la travure représentée en I sur la figure 5 et de l'extrémité de l'élément extrême interne 3a aux positions relevée (représentée en Il sur la figure 5) et de déploiement de la travure, et l'autre de dégagement de l'extrémité de l'élément extrême interne 3a lors du recul du véhicule 1 comme représenté en figure 7.The support device 2 further comprises a support piece 2c of the respective ends of the end elements 3a and 3b, pivotally mounted between the two plates 2b around an axis 2c1 disposed transversely between the two plates 2b and able to cooperate alternately with two abutments 15 and 16 integral with the plates limiting the pivoting travel of the support piece to two extreme angular positions, one supporting the end of the external extreme element 3b in the position for transporting the span shown in I in FIG. 5 and of the end of the internal extreme element 3a in the raised positions (shown in II in FIG. 5) and of deployment of the span, and the other of release of the end of the element internal end 3a when the vehicle 1 recedes as shown in FIG. 7.

La pièce d'appui 2c comprend deux évidements 2c2 et 2c3 à fond arrondi d'appui respectivement de deux axes 3a2 et 3b2 d'extrémité respectifs des éléments extrêmes interne et externe 3a et 3b. Les axes 3a2 et 3b2 sont disposés transversalement à l'axe longitudinal de la travure respectivement aux extrémités de l'élément extrême interne et de l'élément extrême externe. La pièce d'appui 2c comprend de plus deux axes 2c4 et 2c5 faisant saillie transversalement de part et d'autre de la pièce d'appui et à l'extrémité respective de chacun desquels est fixée l'extrémité d'un ressort de traction 17 maintenant la pièce d'appui 2c à l'une ou l'autre de ses positions angulaires extrêmes. Comme mieux représenté en figure 9, les axes 2c4 et 2c5 traversent chacun un trou oblong en forme de haricot 2b4 réalisé au travers de chacune des plaques 2b. Lors du débattement de la pièce d'appui 2c aux deux positions angulaires extrêmes susmentionnées, les axes 2c4 et 2c5 se déplacent dans leur trou oblong correspondant.The support piece 2c comprises two recesses 2c2 and 2c3 with rounded support bases respectively of two axes 3a2 and 3b2 of respective ends of the inner and outer end elements 3a and 3b. The axes 3a2 and 3b2 are arranged transversely to the longitudinal axis of the span respectively at the ends of the internal extreme element and the external extreme element. The support piece 2c further comprises two axes 2c4 and 2c5 projecting transversely on either side of the support piece and at the respective end of each of which is fixed the end of a tension spring 17 maintaining the support piece 2c at one or the other of its extreme angular positions. As best represented in FIG. 9, the axes 2c4 and 2c5 each pass through an oblong bean-shaped hole 2b4 produced through each of the plates 2b. During the movement of the support piece 2c at the two extreme angular positions mentioned above, the axes 2c4 and 2c5 move in their corresponding oblong hole.

Le dispositif de support 2 comprend également un organe de verrouillage 2d de l'axe d'extrémité de l'élément extrême externe 3b audit dispositif et monté pivotant à l'intérieur de la pièce d'appui 2 autour d'un axe 2d1 monté transversalement dans la pièce d'appui 2c. L'organe de verrouillage 2d, réalisé en une seule pièce, comprend une partie formant crochet de retenue 2d2 de l'axe 3b2 à la position de transport de la travure ainsi qu'à la position de celle-ci sur la remorque schématisée en III sur la figure 5 et faisant saillie à ces positions de l'évidement 2c3 pour maintenir l'axe 3b2 dans un espace de retenue défini par en partie l'évidement 2c3 et les bords avant de*laques 2b. L'organe de verrouillage 2d comprendre plus une partie formant bras de pivotement 2d3 de la partie formant crochet, opposée à cette dernière et faisant saillie de l'évidement 2c2 de la pièce d'appui 2c à la position de transport de la travure. Un organe élastique, tel que par exemple un ressort de traction 18, relié à ses extrémités libres respectivement à un point de fixation solidaire de l'organe de verrouillage et à un axe de fixation 2c6 solidaire de la pièce d'appui 2c, rappelle l'organe de verrouillage 2d dans sa direction de verrouillage.The support device 2 also comprises a locking member 2d of the end axis of the external end element 3b to said device and mounted to pivot inside the support piece 2 around an axis 2d1 mounted transversely in the support piece 2c. The locking member 2d, produced in one piece, comprises a part forming a retaining hook 2d2 of the axis 3b2 in the position for transporting the span as well as in the position of the latter on the trailer shown diagrammatically in III in FIG. 5 and projecting at these positions from the recess 2c3 to maintain the axis 3b2 in a retaining space defined by part of the recess 2c3 and the front edges of * lacquers 2b. The locking member 2d further comprises a part forming a pivot arm 2d3 of the hook-forming part, opposite the latter and projecting from the recess 2c2 of the support piece 2c in the position for transporting the span. An elastic member, such as for example a tension spring 18, connected at its free ends respectively to a fixing point secured to the locking member and to a fixing pin 2c6 secured to the support piece 2c, recalls the 2d locking member in its locking direction.

De préférence, deux paires de plaques parallèles 2b comprenant chacune l'ensemble pièce d'appui 2c-organe de verrouillage 2d sont montées sur la lame 2a symétriquement à l'axe longitudinal du véhicule 1 qui coïncide avec l'axe X-X' de la travure montée sur le véhicule.Preferably, two pairs of parallel plates 2b each comprising the support piece 2c-locking member 2d assembly are mounted on the blade 2a symmetrically to the longitudinal axis of the vehicle 1 which coincides with the axis XX 'of the span mounted on the vehicle.

Le fonctionnement du dispositif de support 2, qui découle déjà en partie des explications qui précèdent, va être maintenant décrit plus en détail ci-dessous.The operation of the support device 2, which already follows in part from the foregoing explanations, will now be described in more detail below.

Lorsque le dispositif de support 2 se trouve à la position relevée de transport de la travure, l'axe 3b2 d'extrémité de l'élément 3b est maintenu sur et au dispositif 2 par la partie formant crochet 2d2 de l'organe de verrouillage 2d. Lors du relevage de la travure vers la position approximativement verticale, l'axe d'extrémité 3a2 de l'élément 3a en contactant le bras 2d3 fait pivoter la partie formant crochet dans le sens de déverrouillage représenté en pointillé en figure 5, libérant ainsi l'axe d'extrémité 3a2 de l'élément 3b. Bien entendu, l'axe d'extrémité 3d2 de l'élément 3a est en appui dans l'évidement 2c2 de la pièce d'appui 2c pour assurer le pivotement de la travure lors du déploiement. La figure 6 représente la partie extrême de l'élément interne 2a en appui par son axe d'extrémité 3a2 dans l'évidement 2c2 lorsque la travure est déployée et déposée comme représenté en figure 1 G. A partir de cette position, le véhicule 1 est reculé dans le sens de la flèche R comme indiqué en figure 7 de manière à déplacer le dispositif de support 2 dans le même sens et amener l'extrémité de l'élément interne 3a à se déplacer par gravité d'abord le long d'une branche 2c7 de la pièce 2c définie entre les deux évidements 2c2 et 2c3 pour déclencher le pivotement de la pièce 2c contre la butée 16. Ensuite, les bords 2b2 des plaques 2b et le nez 2b3 forment le chemin de guidage de l'axe d'extrémité 3a2 de l'élément 3a dans la direction descendante comme indiqué par les flèches D de manière à déposer l'extrémité de l'élément 3a et donc la travure sur l'aire de lancement. Après utilisation de la travure, la reprise de l'élément 3a s'effectue en avançant la partie formant nez des plaques 2b vers l'axe d'extrémité 3a2 pour le reprendre sur le nez et les bords 2b2 formant chemin de guidage et l'amener dans son évidement d'appui 2c2 comme indiqué par les flèches A en figure 7. Avant de se loger dans l'évidement 2c2, l'axe d'extrémité 3a2 exerce une action de pivotement sur la pièce d'appui 2c vers la position extrême angulaire définie par la butée 15. Le dispositif se retrouve alors à la position représentée en figure 6. La travure est ensuite relevée comme déjà décrit précédemment pour être ensuite posée sur la remorque. Le déverrouillage de l'axe d'extrémité 3b2 de l'élément 3b avant pose complète de la travure sur la remorque est assuré en exerçant manuellement une pression sur le bras de pivotement 2d3 de la partie formant crochet 2d2.When the support device 2 is in the raised position for transporting the span, the end axis 3b2 of the element 3b is held on and to the device 2 by the hook part 2d2 of the locking member 2d. When raising the span to the approximately vertical position, the end axis 3a2 of the element 3a by contacting the arm 2d3 rotates the hook part in the unlocking direction shown in dotted lines in FIG. 5, thus releasing the end axis 3a2 of element 3b. Of course, the end axis 3d2 of the element 3a is supported in the recess 2c2 of the support piece 2c to ensure the pivoting of the span during deployment. FIG. 6 represents the extreme part of the internal element 2a supported by its end axis 3a2 in the recess 2c2 when the span is deployed and deposited as shown in FIG. 1 G. From this position, the vehicle 1 is moved back in the direction of arrow R as indicated in FIG. 7 so as to move the support device 2 in the same direction and cause the end of the internal element 3a to move by gravity first along a branch 2c7 of the part 2c defined between the two recesses 2c2 and 2c3 to trigger the pivoting of the part 2c against the stop 16. Next, the edges 2b2 of the plates 2b and the nose 2b3 form the guide path of the axis d 'end 3a2 of the element 3a in the downward direction as indicated by the arrows D so as to deposit the end of the element 3a and therefore the span on the launching area. After using the span, the recovery of the element 3a is carried out by advancing the nose portion of the plates 2b towards the end axis 3a2 to resume it on the nose and the edges 2b2 forming the guide path and the bring into its support recess 2c2 as indicated by the arrows A in FIG. 7. Before being housed in the recess 2c2, the end axis 3a2 exerts a pivoting action on the support piece 2c towards the position extreme angular defined by the stop 15. The device is then found in the position shown in Figure 6. The span is then raised as already described above to then be placed on the trailer. The unlocking of the end axis 3b2 of the element 3b before complete installation of the span on the trailer is ensured by manually exerting pressure on the pivot arm 2d3 of the hook part 2d2.

Bien entendu, au lieu de reprendre et relever la travure lorsque le véhicule 1 se trouve à la position indiquée en figure 1 H, il est également possible de reprendre celle-ci lorsque le véhicule se trouve de l'autre côté de la brèche, l'élément extrême externe devenant alors l'élément extrême interne tandis que l'élément extrême interne devient l'élément extrême externe. De plus, le déploiement de la travure peut s'opérer à partir du véhicule 1 situé à l'opposé de la brèche B où se trouve le véhicule comme représenté en figure 1A. Dans ce cas, c'est l'ensemble formant crochet 4 dans le bras 3a1 qui remplira la fonction accomplie par l'ensemble formant crochet 4 du bras 3b1 Il est par ailleurs à noter que le point de fixation permettant d'arrimer le câble de manoeuvre 5 pour relever la travure peut être l'ensemble formant crochet 4 de l'élément extrême interne.Of course, instead of resuming and raising the span when the vehicle 1 is in the position indicated in FIG. 1H, it is also possible to resume it when the vehicle is on the other side of the breach, l the external extreme element then becoming the internal extreme element while the internal extreme element becomes the external extreme element. In addition, the deployment of the span can take place from the vehicle 1 located opposite the breach B where the vehicle is located as shown in Figure 1A. In this case, it is the hook assembly 4 in the arm 3a1 which will fulfill the function accomplished by the hook assembly 4 of the arm 3b1 It should also be noted that the fixing point allowing the cable to be secured maneuver 5 to raise the span may be the hook assembly 4 of the internal end element.

Par ailleurs, le mécanisme représenté en figure 4 a été donné à titre d'exemple, étant bien entendu que d'autre mécanismes assurant des fonctions identiques au mécanisme décrit peuvent être utilisés. Enfin, si la présente invention a été décrite en référence à un engin blindé du génie, elle s'applique néanmoins également à d'autres engins possédant les mêmes fonctions.Furthermore, the mechanism shown in FIG. 4 has been given by way of example, it being understood that other mechanisms ensuring functions identical to the described mechanism can be used. Finally, if the present invention has been described with reference to an armored engineering vehicle, it nevertheless also applies to other vehicles having the same functions.
