Abstract

The anti-theft device comprises essentially a movable vertical plate extending through an opening formed in the rain-strap overlying the doors of the container; this plate is adapted to drop by gravity to a position in which it is located behind lug extensions of the upper ends of the lock rods associated with each door panel to prevent the opening movement of the rods as long as the movable plate is not raised to a position overlying the lugs, this movable plate being rigid with a horizontal cover plate disposed on top of the container and prevented from being raised to a height sufficient for releasing the rods by another stacked container.

Description

On utilise, notamment pour les transports de marchandises par mer, des conteneurs normalisés dont les portes pivotantes sont maintenues en position de fermeture étanche par des crémones constituées par des tiges verticales tournantes qui sont portées par les vantaux de portes dans des paliers solidaires de ces vantaux et qui sont munies à leurs extrémités de verrous dits »cames« qui coopèrent, par rotation des crémones, avec des butées fixes des bâtis de portes de façon à retenir les portes fermées pour . une position angulaire des crémones en libérant ces portes pour une autre position angulaire, pratiquement à 90° de la précédente. Chaque crémone est actionnée par le pivotement horizontal d'un bras de commande appliqué contre la face externe de la porte en position de fermeture.Standard containers are used, in particular for the transport of goods by sea, the pivoting doors of which are held in the sealed closing position by cremones constituted by vertical revolving rods which are carried by the door leaves in bearings integral with these leaves. and which are provided at their ends with locks called "cams" which cooperate, by rotation of the cremone bolts, with fixed stops of the door frames so as to retain the doors closed for. an angular position of the cremones by releasing these doors for another angular position, practically 90 ° from the previous one. Each cremone bolt is actuated by the horizontal pivoting of a control arm applied against the external face of the door in the closed position.

Ces conteneurs se trouvent exposés au vol, soit à bord des navires transporteurs, soit en cours de stationnement dans un parc, par exemple à l'extrémité d'une ligne de transport.These containers are exposed to theft, either on board transport ships, or during parking in a park, for example at the end of a transport line.

L'invention a pour but de s'opposer à l'ouverture des portes de conteneurs, particulièrement quand ces conteneurs sont gerbés les uns sur les autres, en proposant un dispositif associé aux portes de conteneurs pour s'opposer aux manoeuvres des crémones et constitué de façon à ne pas modifier les normes de structure des conteneurs en service, à ne pas altérer l'étanchéité des conteneurs et aussi à faire partie intégrante des conteneurs sans pièce amovible risquant d'être perdue.The object of the invention is to oppose the opening of container doors, particularly when these containers are stacked on top of each other, by proposing a device associated with container doors to oppose the operation of the bolts and consisting so as not to modify the standards of structure of the containers in service, not to alter the tightness of the containers and also to form an integral part of the containers without removable part risking being lost.

Le principe de l'invention consiste à constituer le dispositif de verrouillage anti-vol essentiellement par un élément mobile éclipsable disposé dans un plan vertical, coopérant avec un système de guidage et s'engageant sous l'action de son poids entre au-moins un organe solidaire d'une crémone de vantail de porte en position de fermeture et un élément fixe par rapport au mouvement de rotation de la crémone, de façon à ne permettre la rotation de la crémone pour sa libération et l'ouverture des portes du conteneur que lors d'un soulèvement notable de l'élément mobile éclipsable rendu impossible pour tout conteneur sur lequel est empilé un autre conteneur.The principle of the invention consists in constituting the anti-theft locking device essentially by an eclipsable movable element arranged in a vertical plane, cooperating with a guidance system and engaging under the action of its weight between at least one member secured to a door leaf cremone bolt in the closed position and a fixed element relative to the rotational movement of the cremone bolt, so as to allow rotation of the cremone bolt for its release and the opening of the container doors only during a significant lifting of the movable eclipsing element made impossible for any container on which is stacked another container.

L'élément mobile éclipsable peut être une plaque coulissant dans un guide disposé au-dessus des crémones de porte.The movable eclipsing element can be a plate sliding in a guide arranged above the door bolts.

L'élément mobile éclipsable, en position de verrouillage, peut s'engager entre l'organe solidaire de la crémone et la partie supérieure du bâti de porte.The movable eclipsable element, in the locked position, can engage between the member secured to the lever and the upper part of the door frame.

L'élément mobile éclipsable peut être solidaire d'un chapeau horizontal disposé au-dessus du toit du conteneur, qui limite la descente de cet élément et, lors d'un soulèvement de l'élément mobile, vient s'appuyer sur un élément de la face inférieure du conteneur gerbé juste au-dessus.The movable movable element can be secured to a horizontal cap placed above the roof of the container, which limits the descent of this element and, when the mobile element is raised, comes to rest on an element of the underside of the stacked container just above.

L'ouverture de gouttière à travers laquelle coulisse la plaque verticale de verrouillage peut être établie dans une pièce fixe soudée sur le longeron supérieur du conteneur et sur le toit et cette pièce fixe peut être solidaire de guides fixes disposés au-dessous de l'ouverture de gouttière pour servir de glissières aux bords latéraux de la plaque verticale de verrouillage. La plaque mobile peut porter, au-dessous de l'ouverture de gouttière, une ou plusieurs saillies de retenue rendant la plaque inséparable du conteneur.The gutter opening through which the vertical locking plate slides can be established in a fixed part welded to the upper side member of the container and to the roof, and this fixed part can be fixed to fixed guides arranged below the opening. gutter to serve as slides at the side edges of the vertical locking plate. The movable plate can carry, below the gutter opening, one or more retaining projections making the plate inseparable from the container.

Pour bien faire comprendre l'invention, on en décrira ci-après un exemple d'exécution en référence au dessin annexé dans lequel:

  • la figure 1 est une vue montrant les extrémités supérieures de deux crémones voisines en position de fermeture apparatenant aux deux vantaux de la porte d'un conteneur équipé selon la présente invention;
  • la figure 2 est une vue en perspective du dispositif selon l'invention;
  • les figures 3, 4 et 5 sont des vues respectivement en élévation, en plan et en coupe selon la ligne V-V de la figure 3, montrant la pièce fixe principale du dispositif; et
  • les figures 6, 7 et 8 sont des vues respectivement en élévation, en coupe horizontale VII-VII de la figure 6 et en vue de profil de la pièce mobile.
To clearly understand the invention, an example of execution will be described below with reference to the appended drawing in which:
  • Figure 1 is a view showing the upper ends of two neighboring cremone bolts in the closed position appearing at the two leaves of the door of a container equipped according to the present invention;
  • Figure 2 is a perspective view of the device according to the invention;
  • Figures 3, 4 and 5 are views respectively in elevation, in plan and in section along the line VV of Figure 3, showing the main fixed part of the device; and
  • Figures 6, 7 and 8 are views respectively in elevation, in horizontal section VII-VII of Figure 6 and in profile view of the movable part.

Sur la figure 1, on a indiqué en 1 et 2 les deux vantaux de la porte d'un conteneur qui sont destinés à se fermer de façon étanche l'un contre l'autre et au-dessous d'un bâti fixe 3. Selon la disposition habituelle, le vantail de droite porte des pièces qui, en position de fermeture, recouvrent le vantail de gauche. Chacun des vantaux 1-2 porte des paliers verticaux 4 dans lesquels peuvent pivoter des crémones verticales 5 terminées à leurs extrémités par un verrou 6 coopérant avec des butées 7 portées par le bâti fixe 3. Selon la disposition classique des conteneurs en service, chaque vantail dont l'axe de pivotement est voisin d'un côté de la façade du conteneur, porte extérieurement deux crémones verticales actionnées chacune par un bras manoeuvré dans un plan horizontal et se rabattant contre la face externe du vantail en position de fermeture. Quand un vantail est en position de fermeture et que ses crémones ont été amenées en position angulaire de verrouillage, leurs verrous 6 se trouvent derrière un chrochet des butées fixes 7 tandis que la rotation des crémones et de leurs verrous 6 jusqu'à leur position d'ouverture permet à ces verrous d'échapper aux butées 7.In Figure 1, there are indicated in 1 and 2 the two leaves of the door of a container which are intended to close tightly against one another and below a fixed frame 3. According to in the usual arrangement, the right leaf carries parts which, in the closed position, cover the left leaf. Each of the leaves 1-2 carries vertical bearings 4 in which vertical cremones 5 can pivot, terminated at their ends by a lock 6 cooperating with stops 7 carried by the fixed frame 3. According to the conventional arrangement of the containers in service, each leaf whose pivot axis is close to one side of the front of the container, externally carries two vertical cremone bolts each actuated by an arm maneuvered in a horizontal plane and folding against the external face of the leaf in the closed position. When a leaf is in the closed position and its cremones have been brought into the angular locking position, their latches 6 are behind a hook of fixed stops 7 while the rotation of the cremones and their latches 6 to their position d opening allows these locks to escape the stops 7.

. L'invention s'applique avantageusement aux extrémités supérieures des deux crémones voisines appartenant aux deux vantaux de la porte à protéger contre une ouverture frauduleuse mais on pourrait, sans s'écarter du cadre de l'invention, limiter son application à la crémone voisine du bord ouvrant du vantail de droite puisque celui-ci recouvre en position de fermeture le vantail de gauche qui ne peut donc s'ouvrir que si le vantail de droite est ouvert.. The invention advantageously applies to the upper ends of the two neighboring cremone bolts belonging to the two leaves of the door to be protected against fraudulent opening, but one could, without departing from the scope of the invention, limit its application to the cremone bolt close to the opening edge of the right leaf since it covers the left leaf in the closed position which can therefore only be opened if the right leaf is open.

Dans l'exemple d'exécution représenté au dessin chacune des deux crémones voisines ci-dessus est prolongée vers le haut sur une hauteur suffisante par un appendice 8 en forme de palette qui, en position de fermeture, se trouve parallèle à la paroi de façade du conteneur en étant légèrement écartée du bâti de porte permettre l'interposition, entre ce bâti 3 et les appendices 8, d'une plaque mobile 9 qui devra être soulevée au-dessus des appendices 8 pour permettre la manoeuvre d'ouverture des crémones 5.In the embodiment shown in the drawing, each of the two neighboring cremone bolts above is extended upwards over a sufficient height by an appendage 8 in the form of a pallet which, in the closed position, is parallel to the front wall of the container being slightly spaced from the door frame allowing the interposition, between this frame 3 and the appendages 8, of a movable plate 9 which will have to be lifted above the appendages 8 to allow the opening operation of the cremones 5 .

Comme on l'a déjà indiqué, la plaque mobile 9 est engagée dans une ouverture de gouttière 10 ménagée parallèlement à la façade de conteneur dans une plaque 11 fixée par soudure sur le longeron supérieur du conteneur et sur le toit, au-dessus des deux crémones 5. Cette plaque peut être solidaire de deux goussets latéraux 12.As already indicated, the movable plate 9 is engaged in a gutter opening 10 formed parallel to the container front in a plate 11 fixed by welding on the upper side member of the container and on the roof, above the two cremone bolts 5. This plate can be secured to two lateral gussets 12.

Les parties fixes peuvent comprendre encore deux glissières latérales 13 destinées à recevoir les bords latéraux de la plaque mobile 9.The fixed parts may also comprise two lateral slides 13 intended to receive the lateral edges of the movable plate 9.

La plaque mobile 9 est solidaire d'un chapeau constitué par une plaque soudée 14 se plaçant au-dessus de la plaque fixe 11. La face avant de la plaque mobile porte, dans l'exemple d'exécution représenté, une nervure horizontale 15 en saillie s'opposant à la séparation de la plaque 9 et permettant en outre de soulever la plaque mobile 9 pour libérer les crémones. Cependant, ce soulèvement doit élever la plaque mobile 9 au-dessus des appendices 8 et, conformément à l'invention, ceux-ci sont prolongés suffisamment vers le haut pour interdire le soulèvement de la plaque 9 quand le conteneur correspondant reçoit un conteneur superposé en position de gerbage, quelle que soit l'épaisseur des semelles des éléments de gerbage interposés entre deux conteneurs superposés aux angles des empilages.The movable plate 9 is integral with a cap consisting of a welded plate 14 which is placed above the fixed plate 11. The front face of the movable plate carries, in the embodiment shown, a horizontal rib 15 in projection opposing the separation of the plate 9 and also allowing to lift the movable plate 9 to release the cremones. However, this lifting must raise the movable plate 9 above the appendages 8 and, in accordance with the invention, these are extended sufficiently upward to prohibit the lifting of the plate 9 when the corresponding container receives a stacked container in stacking position, whatever the thickness of the soles of the stacking elements interposed between two containers superimposed on the corners of the stacks.

On comprendra que l'exemple d'exécution décrit ci-dessus et représenté au dessin annexé n'a aucun caractère limitatif et qu'on pourrait envisager diverses modifications ou adjonctions sans s'écarter du cadre de l'invention définie par les revendications annexées.It will be understood that the embodiment described above and shown in the appended drawing has no limiting character and that various modifications or additions could be envisaged without departing from the scope of the invention defined by the appended claims.
