Description
Le secteur technique de la présente invention est celui des dispositifs deThe technical sector of the present invention is that of
blocage en position d'un ouvrant de véhicule. locking in position of a vehicle opening.
De nombreux navires, véhicules militaires ou de chantier comportent des trous d'homme dont l'ouvrant (ou la porte) s'ouvre verticalement. Ces ouvrants ont généralement une masse inférieure à 60 kg et on connaît déjà de nombreux mécanismes assurant le blocage et le maintien en position pour de tels ouvrants. Cependant, pour des ouvrants de plus grande dimension, dont la masse excède parfois les 120 kg, il existe peu de dispositifs de blocage de l'ouvrant et ces dispositifs sont de grande dimension et nécessitent l'intervention d'un servant. Many ships, military vehicles or construction sites have manholes whose opening (or door) opens vertically. These doors generally have a mass of less than 60 kg and there are already numerous mechanisms for locking and holding in position for such doors. However, for larger openings, whose weight sometimes exceeds 120 kg, there are few sash locking devices and these devices are large and require the intervention of a servant.
Le but de la présente invention est de fournir un dispositif pouvant équiper tout type d'ouvrant d'un véhicule tel un navire, un véhicule blindé ou encore un engin de chantier, et réalisant le blocage en position de l'ouvrant sans intervention spécifique d'un servant. Ce dispositif étant de dimension et de masse réduites. The object of the present invention is to provide a device that can equip any type of opening of a vehicle such as a ship, an armored vehicle or a construction machine, and realizing the blocking position of the leaf without specific intervention d a servant. This device being of reduced size and mass.
L'invention a donc pour objet un dispositif de blocage par rapport à son support d'un ouvrant de véhicule pivotant autour d'un axe, caractérisé en ce qu'il comporte un moyen de blocage sensiblement disposé le long de l'axe de rotation de l'ouvrant, ou dans son prolongement, et permettant de solidariser l'ouvrant et son support. The invention therefore relates to a locking device relative to its support of a vehicle opening pivoting about an axis, characterized in that it comprises a locking means substantially disposed along the axis of rotation opening, or in its extension, and to secure the opening and its support.
Selon une autre caractéristique de l'invention, le moyen de blocage est constitué par un crabot apte à être entraîné en translation par une bague pivotante. According to another characteristic of the invention, the locking means is constituted by a clutch capable of being driven in translation by a pivoting ring.
Selon encore une autre caractéristique de l'invention, le 30 crabot est porté par l'axe de rotation de l'ouvrant et se déplace sur cet axe de rotation. According to yet another characteristic of the invention, the clutch is carried by the axis of rotation of the opening and moves on this axis of rotation.
Selon une autre caractéristique de l'invention, le dispositif de blocage comporte une tringle faisant pivoter la bague agissant sur le crabot afin de verrouiller ou de déverrouiller la rotation de l'ouvrant. According to another characteristic of the invention, the locking device comprises a rod pivoting the ring acting on the clutch to lock or unlock the rotation of the opening.
Selon une autre caractéristique de l'invention, la tringle coulisse dans l'ouvrant et est actionnée par un moyen d'entraînement tel un levier. According to another characteristic of the invention, the rod slides in the opening and is actuated by a drive means such as a lever.
Selon une autre caractéristique de l'invention, la tringle entraîne en rotation une bague qui porte au moins une rainure hélicoïdale coopérant avec au moins un pion solidaire du crabot, ce qui assure le déplacement en translation du crabot selon une direction sensiblement orthogonale au déplacement de la tringle. According to another characteristic of the invention, the bead wire rotates a ring which carries at least one helical groove cooperating with at least one pin integral with the dog, which ensures the translational movement of the dog in a direction substantially orthogonal to the movement of the dog. the rod.
Selon une autre caractéristique de l'invention, le dispositif de blocage comporte un élément élastique comprimé entre le crabot et la bague afin d'exercer sur le crabot un effort visant à le rapprocher de sa partie complémentaire et à solidariser les parties mâle et femelle du crabot lorsqu'elles sont en vis-à-vis. According to another characteristic of the invention, the locking device comprises a resilient element compressed between the clutch and the ring in order to exert on the clutch a effort to bring it closer to its complementary part and to secure the male and female parts of the clutch. dog when they are facing each other.
Un tout premier avantage du dispositif selon l'invention réside dans sa compacité et dans sa disposition au niveau de l'axe de rotation de l'ouvrant. A first advantage of the device according to the invention lies in its compactness and in its arrangement at the axis of rotation of the opening.
Un autre avantage réside dans sa possibilité d'adaptation et de montage sur un quelconque type d'ouvrant pivotant autour d'un axe. Another advantage lies in its ability to adapt and mount on any type of opening pivoting about an axis.
Un autre avantage réside dans sa capacité à supporter des ouvrants de masse importante. Another advantage lies in its ability to withstand large mass openings.
D'autres caractéristiques, détails et avantages de l'invention ressortiront plus clairement de la description donnée ci-après à titre indicatif en relation avec des dessins dans lesquels: - les figure la à le sont des représentations cinématiques de l'invention dans différentes positions, - la figure 2 est une vue en coupe d'un dispositif selon l'invention, et - la figure 3 est une vue de dessus d'un dispositif selon l'invention, sans le crabot mâle. Other features, details and advantages of the invention will emerge more clearly from the description given below as an indication in relation to drawings in which: - Figures la are kinematic representations of the invention in different positions - Figure 2 is a sectional view of a device according to the invention, and - Figure 3 is a top view of a device according to the invention without the male clutch.
Les figures la à ic sont des représentations cinématiques illustrant le principe de l'invention. Le dispositif 1 de blocage selon l'invention comprend un crabot femelle 5 solidaire du support de l'ouvrant, support lui-même solidaire du véhicule, un crabot mâle 4, un élément élastique 9, une bague 12 comportant au moins une rainure hélicoïdale 19, une tringle 6 et un levier de manoeuvre 13. Le crabot mâle 4 comporte des dents 14 destinées à coopérer avec des empreintes 15 de profil complémentaire porté par le crabot femelle 5. Le levier 13 est relié à l'ouvrant (non représenté sur ces figures) par une liaison rotule 16 et coopère avec la tringle 6 afin de déplacer cette dernière en translation dans une glissière 17 solidaire de l'ouvrant. La tringle 6 est reliée à la bague 12 par l'intermédiaire d'un doigt 10 afin de transformer le mouvement de translation de la tringle en une rotation de cette bague 12. La bague 12 comporte une ou plusieurs rainures hélicoïdales 19 dans lesquelles se déplacent des pions 18 solidaires du crabot mâle 4. L'élément élastique 9 est comprimé entre la bague 12 et le crabot mâle 4. Une telle disposition permet avantageusement de déplacer en translation le crabot 4 selon une direction sensiblement orthogonale au déplacement de la tringle 6. Figures la to ic are kinematic representations illustrating the principle of the invention. The blocking device 1 according to the invention comprises a female clutch 5 secured to the support of the opening, support itself secured to the vehicle, a male clutch 4, an elastic member 9, a ring 12 having at least one helical groove 19 , a rod 6 and an operating lever 13. The male dog 4 comprises teeth 14 intended to cooperate with fingerprints 15 complementary profile carried by the female dog 5. The lever 13 is connected to the opening (not shown on these Figures) by a ball joint 16 and cooperates with the rod 6 to move the latter in translation in a slide 17 secured to the opening. The rod 6 is connected to the ring 12 via a finger 10 in order to transform the translation movement of the rod into a rotation of this ring 12. The ring 12 has one or more helical grooves 19 in which move pins 18 integral with the male clutch 4. The elastic element 9 is compressed between the ring 12 and the dog clutch 4. Such an arrangement advantageously allows to move in translation the dog clutch 4 in a direction substantially orthogonal to the movement of the rod 6.
Le fonctionnement du dispositif est le suivant: La figure la représente le dispositif de blocage en position intermédiaire: le dispositif a été déverrouillé et l'ouvrant est ouvert dans une position intermédiaire entre deux positions de blocage. Pour cela, la tringle 6 a été déplacée selon la direction dl, la bague 12 a donc réalisé une rotation ayant déplacé le pion 18. En conséquence, la bague 12 a écarté par translation le crabot mâle 4 du crabot femelle 5 et comprimé l'élément élastique 9. Les dents 14 du crabot mâle 4 ne se trouvent face à aucun profil complémentaire et glissent sur la surface plane du crabot femelle 5. En pivotant autour de son axe, l'ouvrant entraîne en rotation la bague 12, ainsi que le crabot male 4. La rotation du crabot mâle 4 permet aux dents 14 de se trouver face au profil complémentaire 15 du crabot femelle 5 (figure lb). Sous l'action de l'élément élastique 9, les dents 14 pénètrent dans le profil complémentaire 15 du crabot femelle 5. Le déplacement du crabot mâle 4 entraîne, par l'intermédiaire des pions 18 se déplaçant dans les rainures hélicoïdales 19, la rotation de la bague 12. La tringle 6, entraînée par la rotation de la bague 12, subit une translation selon la direction d2, ce qui modifie également la position du levier 13. L'ouvrant est ainsi verrouillé en position. Tant que les deux parties du crabot sont solidaires, tout déplacement de l'ouvrant sera impossible. Le déverrouillage de l'ouvrant s'effectue par l'intermédiaire du levier 13. En actionnant le levier 13, le servant déplace la tringle 6 selon la direction dl (figure lc) et sépare les profils complémentaires 14 et 15 des deux parties du crabot. L'ouvrant peut de nouveau être déplacé en rotation. Si le levier est relâché sans que l'ouvrant n'ait été déplacé, les deux profils du crabot se re- solidarisent et l'ouvrant est verrouillé. Il faut donc réaliser un déplacement suffisant en rotation de l'ouvrant avant de relâcher le levier 13 afin de dégager les deux parties 3 et 4 du crabot. The operation of the device is as follows: FIG. 1a shows the locking device in the intermediate position: the device has been unlocked and the opening is open in an intermediate position between two locking positions. For this, the rod 6 has been moved in the direction dl, the ring 12 has thus made a rotation having moved the pin 18. As a result, the ring 12 spaced by translation the male clutch 4 of the female clutch 5 and compressed the elastic element 9. The teeth 14 of the male dog 4 are not faced with any complementary profile and slide on the flat surface of the female dog 5. By pivoting about its axis, the opening rotates the ring 12, as well as the 4. The rotation of the male clutch 4 allows the teeth 14 to face the complementary profile 15 of the female clutch 5 (Figure lb). Under the action of the elastic element 9, the teeth 14 penetrate the complementary profile 15 of the female dog 5. The displacement of the male dog 4 causes, through the pins 18 moving in the helical grooves 19, the rotation of the ring 12. The rod 6, driven by the rotation of the ring 12, is translated in the direction d2, which also changes the position of the lever 13. The door is thus locked in position. As long as the two parts of the clutch are integral, any displacement of the opening will be impossible. The release of the opening is effected by means of the lever 13. By actuating the lever 13, the serving moves the rod 6 in the direction dl (Figure lc) and separates the complementary profiles 14 and 15 of the two parts of the clutch . The opening can be moved again in rotation. If the lever is released without the sash being moved, the two dog clutch profiles are fixed and the sash is locked. It is therefore necessary to make sufficient movement in rotation of the opening before releasing the lever 13 to clear the two parts 3 and 4 of the dog.
La figure 2 est une vue en coupe d'un exemple de réalisation de l'invention. Dans cet exemple de réalisation, un ouvrant 2 est relié à son support 3 au moyen d'un bras 20 solidaire de l'ouvrant 2 et pivotant autour d'un axe de rotation 11. Le bras 20 comporte un alésage 17 dans lequel peut glisser la tringle 6 afin de réaliser la glissière 17. Figure 2 is a sectional view of an exemplary embodiment of the invention. In this embodiment, an opening 2 is connected to its support 3 by means of an arm 20 integral with the opening 2 and pivoting about an axis of rotation 11. The arm 20 has a bore 17 in which can slide the rod 6 to achieve the slide 17.
Le levier 13 est relié à la tringle 6 au moyen d'un téton 19 dont l'extrémité 22 de forme sphérique coopère avec une ouverture cylindrique de la tringle 6 afin de réaliser une liaison du type linéaire annulaire. The lever 13 is connected to the rod 6 by means of a stud 19 whose end 22 of spherical shape cooperates with a cylindrical opening of the rod 6 in order to make a connection of the annular linear type.
Dans cet exemple de réalisation, l'élément élastique 9 est un ressort hélicoïdal (on pourrait remplacer ce ressort par un autre élément élastique, par exemple un empilement de rondelles Belleville). Le crabot femelle 5 est solidarisé au support 3 de l'ouvrant au moyen d'une plaque 21 de fixation et comporte deux paires de rainures 15a, 15b, correspondant à deux positions de blocage de l'ouvrant. In this exemplary embodiment, the elastic element 9 is a helical spring (this spring could be replaced by another elastic element, for example a stack of Belleville washers). The female clutch 5 is secured to the support 3 of the opening by means of a plate 21 for fixing and has two pairs of grooves 15a, 15b, corresponding to two locking positions of the opening.
La figure 3 est une vue de dessus du même dispositif que celui illustré par la figure 2 mais représenté sans le crabot mâle 4, pour une meilleure compréhension de la disposition des éléments. Cette figure permet d'observer la disposition des pions 18 dans les rainures hélicoïdales 19 de la bague 12. Dans ce mode préféré de réalisation, l'axe de rotation 11 du crabot mâle 4 et de la bague 12 est également l'axe de rotation de l'ouvrant et le bras 20 remplit le rôle de l'une des charnières de l'ouvrant. On pourra également réaliser l'invention avec un axe de rotation du dispositif de blocage indépendant de l'axe de rotation des charnières de l'ouvrant (notamment dans le cas de l'adaptation du dispositif à un ouvrant déjà monté sur un véhicule) mais cet axe devra impérativement être disposé au niveau de l'axe de rotation de l'ouvrant. Figure 3 is a top view of the same device as that shown in Figure 2 but shown without the male clutch 4, for a better understanding of the arrangement of the elements. This figure makes it possible to observe the arrangement of the pins 18 in the helical grooves 19 of the ring 12. In this preferred embodiment, the axis of rotation 11 of the male clutch 4 and the ring 12 is also the axis of rotation. of the opening and the arm 20 fulfills the role of one of the hinges of the opening. It will also be possible to realize the invention with an axis of rotation of the locking device independent of the axis of rotation of the hinges of the opening (particularly in the case of adapting the device to an opening already mounted on a vehicle) but this axis must imperatively be arranged at the axis of rotation of the opening.
Dans ces exemples de réalisation, on a représenté un crabot mâle 4 mobile et un crabot femelle 5 solidaire du support 3. On pourra évidemment réaliser l'invention en intervertissant le crabot mâle et le crabot femelle sans que le résultat n'en soit modifié. In these exemplary embodiments, there is shown a movable male dog 4 and a female clutch 5 secured to the support 3. It will obviously be possible to achieve the invention by reversing the male clutch and the female claw without the result being modified.
On pourra également réaliser l'invention avec un crabot femelle comportant un autre nombre de rainures. Un nombre plus important de rainures permettra de verrouiller l'ouvrant selon plusieurs positions différentes. It will also be possible to realize the invention with a female clutch comprising another number of grooves. A larger number of grooves will lock the opening in several different positions.
Un capotage de protection (non représenté) sera disposé autour de la charnière et notamment des crabots afin d'empêcher l'encrassement de ces derniers et empêcher également le coincement des doigts d'un opérateur. A protective cover (not shown) will be arranged around the hinge and in particular jaw claws to prevent clogging of the latter and also prevent the jamming of the fingers of an operator.
Pour réduire l'encrassement des crabots, on pourra aussi donner aux extrémités des dents ainsi qu'aux fonds des rainures des crabots un profil en biseau. Une telle disposition permettra lors de chaque verrouillage des crabots de nettoyer le fond des rainures. To reduce the fouling of the claws, we can also give the ends of the teeth and the bottoms of the dog teeth a profile bevel. Such an arrangement will allow each locking jaw claws to clean the bottom of the grooves.
