Description

La présente invention est relative aux dispositifs de verrouillage des portes arrière de camions-bennes bascu­lantes, ou autres véhicules analogues, adaptés pour déverser leur chargement par l'arrière et comportant, dans ce but, une porte arrière à deux battants s'ouvrant vers l'extérieur afin de dégager entièrement le passage du chargement.The present invention relates to locking devices for the rear doors of dump trucks, or other similar vehicles, adapted for dumping their cargo from the rear and comprising, for this purpose, a rear door with two leaves opening towards the outside to fully clear the passage of the load.

Les véhicules de ce type sont largement utilisés dans tous les travaux de construction, de terrassement ou analogues dans lesquels divers matériaux doivent être trans­portés et déversés en un lieu quelconque, sur le chantier ou, au contraire, en un point éloigné de ce dernier.Vehicles of this type are widely used in all construction, earthmoving or the like in which various materials are to be transported and dumped at any location, on the site or, on the contrary, at a point distant therefrom.

On connait différents systèmes de fermeture arrière pour les véhicules de ce type. L'un de ces systèmes comporte un panneau d'une seule pièce, articulé par son bord supérieur sur un axe horizontal et verrouillé par son bord inférieur sur la caisse du véhicule.We know different rear locking systems for vehicles of this type. One of these systems comprises a single-piece panel, articulated by its upper edge on a horizontal axis and locked by its lower edge on the vehicle body.

Dans un autre système, la porte arrière est à deux battants montés pivotants sur des axes verticaux, sur les deux parois latérales du véhicule.In another system, the rear door is with two leaves pivotally mounted on vertical axes, on the two side walls of the vehicle.

Dans ce dernier type de système, auquel l'invention est particulièrement relative, les deux battants sont ver­rouillés à leur jonction, au milieu de la largeur de la caisse du véhicule.In the latter type of system, to which the invention is particularly relative, the two leaves are locked at their junction, in the middle of the width of the vehicle body.

Avec l'un ou l'autre de ces systèmes, et plus par­ticulièrement avec le second, la commande du déverrouillage de la porte doit être telle que l'opérateur ne se trouve pas dans la trajectoire de sortie des matériaux, qui peuvent commencer à s'écouler par gravité, même si le déverrouillage est effectué alors que la benne n'est pas encore basculée, afin d'éviter tout accident.With one or the other of these systems, and more particularly with the second, the control of the unlocking of the door must be such that the operator is not in the exit path of the materials, which can begin to s '' run by gravity, even if the unlocking is carried out while the bucket is not yet tilted, in order to avoid any accident.

L'invention a en conséquence pour but de fournir un dispositif de verrouillage d'un système de porte arrière à deux battants pour camion-benne ou autre véhicule, incli­nable, dont la commande soit assurée depuis l'un des côtés du véhicule afin que l'opérateur puisse l'actionner en toute sécurité en se trouvant hors de la trajectoire de sortie du matériau à décharger, c'est-à-dire depuis un point situé sur le côté du véhicule.The object of the invention is therefore to provide a device for locking a tilting rear door system for a dump truck or other vehicle, which can be controlled from one of the sides of the vehicle so that the operator can operate it safely while out of the path of exit of the material to be discharged, that is to say from a point located on the side of the vehicle.

L'invention a pour objet à cet effet un dispositif de verrouillage d'un crochet monté pivotant sur le bord libre d'une porte et coopérant avec des moyens de retenue solidaire de la partie dormante, caractérisé en ce qu'il comprend sur ladite partie dormante un pène coulissant adapté pour coopérer avec une gâche formée sur le crochet, et sollicité élastiquement en position de verrouillage, ce pène ayant un prolongement rigide entourant au moins partiel­lement le crochet dans sa position d'accrochage, et une butée de retenue dudit prolongement en position rétractée, effaçable élastiquement.The subject of the invention is to this end a device for locking a hook pivotally mounted on the free edge of a door and cooperating with retaining means integral with the dormant part, characterized in that it comprises on said part a sliding bolt adapted to cooperate with a keeper formed on the hook, and resiliently biased in the locking position, this bolt having a rigid extension at least partially surrounding the hook in its hooking position, and a stop for retaining said extension in retracted position, elastically erasable.

Suivant une autre caractéristique de l'invention le pène est monté coulissant dans un organe de guidage fixé sur la partie dormante, dans lequel il est sollicité par un ressort, et est relié à un organe de commende à distance.According to another characteristic of the invention, the bolt is slidably mounted in a guide member fixed to the dormant part, in which it is biased by a spring, and is connected to a remote control member.

Suivant une autre caractéristique, ledit prolonge­ment rigide est un cadre rectangulaire délimitant une ouver­ture allongée apte à recevoir la tête du crochet, ce cadre étant fixé sur le pène par l'un de ses petits côtés.According to another characteristic, said rigid extension is a rectangular frame delimiting an elongated opening capable of receiving the head of the hook, this frame being fixed on the bolt by one of its short sides.

D'une façon avantageuse, l'extrémité du pène fait saillie dans ladite ouverture, la distance entre cette extrémité du pène et le côté opposé dudit cadre étant au moins égale à la largeur de la tête du crochet.Advantageously, the end of the bolt projects into said opening, the distance between this end of the bolt and the opposite side of said frame being at least equal to the width of the head of the hook.

Suivant un mode de réalisation, ladite butée effa­çable élastiquement comprend une lame élastique fixée par une extrémité sur l'organe de guidage du pène et s'étendant parallèlement à celui-ci, sur le côté dudit cadre opposé au crochet, et une saillie dirigée vers le cadre fixée sur son extrémité opposée, l'agencement étant tel qu'à l'état non contraint de la lame, ladite saillie se trouve en face dudit cadre.According to one embodiment, said elastically erasable stop comprises an elastic blade fixed by one end to the guide member of the bolt and extending parallel to the latter, on the side of said frame opposite the hook, and a projection directed towards the frame fixed on its opposite end, the arrangement being such that in the unstressed state of the blade, said projection is located opposite said frame.

De préférence, il est prévu des moyens solidaires du crochet, pour entraîner celui-ci angulairement et manuel­lement de sa position d'ouverture dans sa position d'accro­chage.Preferably, means are provided integral with the hook, to drive the latter angularly and manually from its open position to its hooking position.

D'une façon commode lesdits moyens de commande à distance du pène sont constitués par un levier articulé sur un côté de la partie dormante.Conveniently, said remote control means of the bolt are constituted by a lever articulated on one side of the sleeping part.

Dans ce dispositif, la gâche est constituée par une encoche ménagée dans la partie arrière de la tête du crochet, opposée à sa partie coopérant avec les moyens de retenue, en regard du pène lorsque ledit crochet se trouve dans sa position d'accrochage.In this device, the keeper is constituted by a notch formed in the rear part of the hook head, opposite its part cooperating with the retaining means, facing the bolt when said hook is in its hooking position.

Le dispositif suivant l'invention est également utilisable sur des portes à deux battants et trouve une ap­plication particulièrement avantageuse dans le verrouillage des portes de bennes basculantes et il sera décrit ci-après à titre d'exemple non limitatif dans une telle application.The device according to the invention can also be used on doors with two leaves and finds a particularly advantageous application in the locking of doors of tipping bodies and it will be described below by way of nonlimiting example in such an application.

La description qui va suivre en regard du dessin annexé à titre d'exemple non limitatif permettra de bien cmprendre comment l'invention peut être mise en pratique.

  • La figure 1 est une vue en plan de dessous de l'ex­trémité arrière d'une benne basculante fermée par une porte à deux battants maintenus fermés au moyen d'un dispositif de verrouillage suivant l'invention, représenté en position verrouillée.
  • La figure 2 est une vue analogue à celle de la figure 1, mais montrant le dispositif en position d'ouver­ture.
  • La figure 3 est une vue en bout, d'arrière, de la benne, la porte étant fermée.
  • La figure 4 est une vue partielle avec arrachement, prise dans le sens de la flèche A à la figure 3.
The description which follows with reference to the attached drawing by way of nonlimiting example will make it possible to understand how the invention can be put into practice.
  • Figure 1 is a bottom plan view of the rear end of a tipper closed by a door with two leaves kept closed by means of a locking device according to the invention, shown in the locked position.
  • Figure 2 is a view similar to that of Figure 1, but showing the device in the open position.
  • Figure 3 is an end view, rear, of the bucket, the door being closed.
  • FIG. 4 is a partial view with cutaway, taken in the direction of the arrow A in FIG. 3.

En se référant au dessin, la référence 1 désigne la surface inférieure du fond d'une benne basculante auto­mobile, fermée par une porte à deux battants A et B arti­culés sur les côtés de la benne afin de pivoter autour d'axes verticaux latéraux 2 montés sur les ridelles; le fond 1 constitue la partie dormante de la porte A B.Referring to the drawing, the reference 1 designates the bottom surface of the bottom of an automobile dump body, closed by a door with two leaves A and B hinged on the sides of the body in order to pivot around lateral vertical axes 2 mounted on the drop sides; the bottom 1 constitutes the dormant part of the door A B.

Sur son bord vertical opposé à son axe 2, le bat­tant B comporte un autre axe vertical 3, monté rotatif et portant un crochet fixé à chacune de ses extrémités de façon à tourner solidairement, ces deux crochets 4, 5 s'étendant parallèlement dans le même sens par rapport à l'axe 3.On its vertical edge opposite its axis 2, the leaf B has another vertical axis 3, mounted to rotate and carrying a hook fixed at each of its ends so as to rotate integrally, these two hooks 4, 5 extending parallel in the same direction with respect to axis 3.

En se référant à la figure 3, qui montre la benne basculante vue d'arrière en bout, le crochet 4 est fixé à l'extrémité inférieure de l'axe 3 et le crochet 5 est fixé sur son extrémité supérieure.Referring to FIG. 3, which shows the tipper body viewed from rear to end, the hook 4 is fixed to the lower end of the axis 3 and the hook 5 is fixed on its upper end.

Le crochet inférieur 4 comporte une tête convexe 6 ayant un bec avant 7 adapté pour coopérer avec un organe de retenue constitué par un téton 8 en saillie sur la partie dormante 1 et, dans sa partie arrière, un redan 9 formant une gâche pouvant recevoir un pène, comme on le décrira dans la suite.The lower hook 4 comprises a convex head 6 having a front spout 7 adapted to cooperate with a retaining member constituted by a stud 8 projecting from the dormant part 1 and, in its rear part, a step 9 forming a keeper capable of receiving a bolt, as will be described below.

Le crochet supérieur 5 coopère avec un téton 8ʹ en saillie sur le battant A (figure 3) et ce dernier présente une feuillure 10 apte à recevoir le bord libre du battant B, comme connu en soi.The upper hook 5 cooperates with a stud 8ʹ projecting from the wing A (FIG. 3) and the latter has a rebate 10 capable of receiving the free edge of the wing B, as known per se.

Le dispositif de verrouillage compend un pène 11 monté coulissant dans un organe de guidage qui, selon l'exemple représnté, est un cylindre 12 monté sur la sur­face inférieure 1 de la benne (dormant de la porte).The locking device comprises a bolt 11 slidably mounted in a guide member which, according to the example shown, is a cylinder 12 mounted on the lower surface 1 of the bucket (door frame).

Un ressort hélicoïdal 13 sollicite le pène 11 vers l'extérieur du cylindre 12, en direction du téton 8 et du crochet 4.A helical spring 13 biases the bolt 11 towards the outside of the cylinder 12, in the direction of the stud 8 and the hook 4.

En outre, le pène 11 est relié par une tringle 14 s'étendant à travers le ressort 13, à un organe de commande à distance qui, suivant l'exemple représenté, est constitué par un levier 15 articulé sur la partie dormante 1.In addition, the bolt 11 is connected by a rod 14 extending through the spring 13, to a remote control member which, according to the example shown, consists of a lever 15 articulated on the dormant part 1.

Un organe rigide 16 constitué suivant l'exemple représenté par un cadre rectangulaire est fixé par l'un de ses petits côtés sur le pène 11.A rigid member 16 formed according to the example represented by a rectangular frame is fixed by one of its short sides to the bolt 11.

Le cadre 16 délimite une ouverture allongée 17 et est fixé sur le pène de telle sorte que l'extrémité de celui-ci fait saillie dans ladite ouverture (figure 4).The frame 16 delimits an elongated opening 17 and is fixed to the bolt so that the end of the latter projects into said opening (FIG. 4).

La largeur de l'ouverture 17 est un peu supérieure à l'épaisseur de la tête 6 du crochet 4, et sa longueur, entre l'extrémité du pène et celle du cadre 16 est au moins égale à la largeur de la tête 6 du crochet, du bec 7 au redan 9.The width of the opening 17 is slightly greater than the thickness of the head 6 of the hook 4, and its length, between the end of the bolt and that of the frame 16 is at least equal to the width of the head 6 of the hook, from beak 7 to step 9.

L'agencement est tel que l'organe 16 de prolonge­ment du pène est en contact avec le téton 8 sur lequel il peut glisser lorsque le pène 11 coulisse dans le cylindre 12 de guidage, le téton 8 comportant à cet effet un méplat (visible à la figure 2).The arrangement is such that the member 16 for extending the bolt is in contact with the stud 8 on which it can slide when the bolt 11 slides in the guide cylinder 12, the stud 8 having for this purpose a flat (visible at Figure 2).

Une lame flexible 18 en acier est fixée par une extrémité sur le cylindre 12 de façon à s'étendre le long du pène et de son prolongement 16, sur le côté de celui-ci qui est opposé au téton 8, fermant ainsi l'ouverture 17, lorsque la lame 18 est à l'état non contraint.A flexible steel blade 18 is fixed by one end to the cylinder 12 so as to extend along the bolt and its extension 16, on the side of the latter which is opposite to the stud 8, thus closing the opening 17, when the blade 18 is in the unstressed state.

En outre la lame 18 comporte à son extrémité oppo­sée au cylindre 12 une butée 19 faisant saillie vers le cadre 16, la distance entre la butée 19 et l'extrémité du cylindre 12 étant inférieure à la longueur totale du pène 11 et de son prolongement 16 lorsque le pène est entièrement sorti du cylindre.In addition, the blade 18 has at its end opposite the cylinder 12 a stop 19 projecting towards the frame 16, the distance between the stop 19 and the end of the cylinder 12 being less than the total length of the bolt 11 and its extension 16 when the bolt is fully extended from the cylinder.

Il et enfin prévu au voisinage du crochet 4 une douille 20 solidaire de l'axe 3 dans un but qui apparaitra dans la suite.It and finally provided in the vicinity of the hook 4 a socket 20 secured to the axis 3 for a purpose which will appear later.

Le fonctionnement du dispositif est le suivant.The operation of the device is as follows.

En position de fermeture des portes et de verrouil­lage du crochet 4 sur le téton 8 et du crochet 5 sur le téton 8ʹ, la tête 6 du crochet 4 est engagée dans l'ouver­ture 17 du cadre 16 qui l'entoure, et le pène 11 est engagé sous le redan 9.In the closed position of the doors and the locking of the hook 4 on the stud 8 and of the hook 5 on the stud 8ʹ, the head 6 of the hook 4 is engaged in the opening 17 of the frame 16 which surrounds it, and the bolt 11 is engaged under step 9.

Le cylindre 12 étant fixé sur la partie dormante et le cadre 16 étant en appui sur le téton 8, le crochet 4 est verrouillé positivement et ne peut se dégager du téton 8.The cylinder 12 being fixed on the dormant part and the frame 16 being in abutment on the stud 8, the hook 4 is locked positively and cannot be released from the stud 8.

Dans cette position, la tête convexe 6 du crochet fait saillie à travers l'ouverture 17 et maintient ainsi la lame 18 espacée du cadre 16.In this position, the convex head 6 of the hook projects through the opening 17 and thus keeps the blade 18 spaced from the frame 16.

Pour déverrouiller le dispositif, il sufit de ré­tracter le pène en actionnant le levier 15, à l'encontre de l'action du ressort 13.To unlock the device, it suffices to retract the bolt by actuating the lever 15, against the action of the spring 13.

Dans ce mouvement de retrait, la tête du crochet, entourée par le cadre 16, est entraînée en arrière et se dégage du téton 8 en même temps que le pène 11 se dégage du redan 9.In this withdrawal movement, the hook head, surrounded by the frame 16, is driven back and is released from the stud 8 at the same time as the bolt 11 is released from the step 9.

Les crochets 4 et 5 tournent solidairement en libé­rant les portes. Simultanément la tête 6 du crochet 4 se dégage du cadre 16 et la lame flexible 18 reprend élasti­quement sa position le long du cadre 16, avec sa butée 19 venant se placer devant l'extrémité de celui-ci, en maintenant ainsi le pène en position rétractée, à l'encon­tre de l'action du ressort 13 (figure 2).The hooks 4 and 5 rotate integrally, freeing the doors. Simultaneously the head 6 of the hook 4 emerges from the frame 16 and the flexible blade 18 resumes its position elastically along the frame 16, with its stop 19 coming to be placed in front of the end of the latter, in thus maintaining the bolt in the retracted position, against the action of the spring 13 (Figure 2).

Dans cette position le dispositif est prêt à ver­rouiller automatiquement les portes. Lorsque celles-ci sont refermées, la tête du crochet 4 s'engage de nouveau dans l'ouverture 17 du cadre 16 en repoussant la lame 18, ce qui libère l'ensemble cadre/pène.In this position the device is ready to automatically lock the doors. When these are closed, the hook head 4 engages again in the opening 17 of the frame 16 by pushing the blade 18, which releases the frame / bolt assembly.

Il suffit alors à l'opérateur de faire tourner l'axe 3, par exemple au moyen d'un levier (non représenté) engagé dans la douille 20 pour ramener les crochets 4, 5 en position d'accrochage, le pène 11 revenant s'engager en prise avec le redan 9 sous l'action du ressort 13.It then suffices for the operator to rotate the axis 3, for example by means of a lever (not shown) engaged in the socket 20 to bring the hooks 4, 5 back into the hooking position, the bolt 11 returning s engage with the step 9 under the action of the spring 13.

On remarquera que le levier 15 peut être remplacé par un dispositif d'actionnement quelconque connu, élec­trique, hydraulique, pneumatique ou autre, à commande à distance qui permet à l'opérateur, comme le levier 15, de déverrouiller la porte sans se trouver devant elle, comme cela est nécessaire dans le cas des bennes basculantes.Note that the lever 15 can be replaced by any known actuation device, electric, hydraulic, pneumatic or other, remote control which allows the operator, like the lever 15, to unlock the door without being in front it, as is necessary in the case of tipping bodies.
