Description

La présente invention se rapporte à un dispositif de verrouillage d'un couvercle sur une cuve de conteneur, notamment un bac roulant, et à un conteneur comportant au moins un tel dispositif et utilisable notamment dans la collecte mécanisée de déchets, notamment de déchets ménagers.The present invention relates to a device for locking a cover on a container tank, in particular a rolling bin, and to a container comprising at least one such device and usable in particular in the mechanized collection of waste, in particular household waste.

Pour de tels conteneurs destinés à séjourner plus ou moins longtemps sur la voie publique tant à l'état vide qu'à l'état rempli, il est souhaitable de maintenir le couvercle fermé et verrouillé sur la cuve pour empêcher que des personnes non autorisées n'accèdent à l'intérieur de la cuve, et ce, afin de leur interdire d'extraire des matières contenues dans le bac, par malveillance ou en vue de leur récupération, ou pour y déposer d'autres déchets que ceux autorisés, notamment dans le cadre d'une collecte sélective.For such containers intended to stay more or less long on the public road both in the empty state and in the filled state, it is desirable to keep the lid closed and locked on the tank to prevent unauthorized persons from n '' access the inside of the tank, in order to prevent them from extracting materials contained in the tank, maliciously or with a view to their recovery, or to deposit there other waste than that authorized, in particular in as part of a selective collection.

Il a déjà été proposé de munir de tels conteneurs d'un dispositif de verrouillage de couvercle manoeuvrable à l'aide d'une clef, notamment une clef personnalisée.It has already been proposed to provide such containers with a device for locking the lid that can be operated using a key, in particular a personalized key.

Cette solution n'est pas totalement satisfaisante car, en vue de la collecte, le préposé à celle-ci doit pouvoir provoquer l'ouverture du couvercle sans disposer de la clef correspondante.This solution is not entirely satisfactory because, for collection, the attendant must be able to cause the opening of the cover without having the corresponding key.

On connait par ailleurs par US-A-4155584 un dispositif de verrouillage d'un couvercle sur une cuve de conteneur, notamment un bac roulant, correspondent au préambule de la revendication 1 et comportant une pièce de blocage montée pivotante entre une position assurant le verrouillage du couvercle en position fermée sur la cuve et une position de déverrouillage libérant le couvercle, et un organe de manoeuvre coopérant avec ladite pièce de blocage pour amener la pièce de blocage en position de déverrouillage pour une position inclinée prédéterminée du conteneur.We also know from US-A-4155584 a device for locking a cover on a container tank, in particular a rolling container, correspond to the preamble of claim 1 and comprising a blocking piece pivotally mounted between a position ensuring the locking of the cover in the closed position on the tank and an unlocking position releasing the cover, and an operating member cooperating with said blocking piece to bring the blocking piece in the unlocking position for a predetermined inclined position of the container.

Dans ce document, cependant, l'organe de manoeuvre est constitué d'une masse mobile en rotation selon un trajet courbe guidé et est relié par une tringlerie ou par l'intermédiaire d'une seconde masse mobile en translation guidée à la pièce de blocage pivotante.In this document, however, the operating member consists of a mass that can move in rotation along a guided curved path and is connected by a linkage or by means of a second mass that can move in guided translation to the blocking part. swivel.

La présente invention se propose de réaliser un dispositif de verrouillage présentant une structure moins encombrante, une cinématique moins complexe et donc moins fragile et plus fiable que le dispositif antérieur.The present invention proposes to produce a locking device having a less bulky structure, a less complex kinematics and therefore less fragile and more reliable than the previous device.

Cet objectif est affeint grâce au dispositif défini par la revendication 1.This objective is achieved thanks to the device defined by claim 1.

On comprend que, selon l'invention, l'organe de manoeuvre est en prise directe avec la pièce de blocage, et peut être actionné d'une part à l'aide d'un moyen d'actionnement traditionnel tel qu'une clef appropriée, en particulier une clef personnalisée, et d'autre part lors de la modification de l'orientation du conteneur, comme cela est le cas notamment lors de la phase de soulèvement et de pivotement du conteneur en vue de son vidage dans un camion de collecte.It is understood that, according to the invention, the operating member is in direct engagement with the blocking part, and can be actuated on the one hand using a traditional actuation means such as an appropriate key , in particular a personalized key, and secondly when changing the orientation of the container, as is the case in particular during the lifting and pivoting phase of the container for emptying into a collection truck .

La pièce de blocage se trouve alors déplacée dans sa position de déverrouillage libérant le couvercle qui s'ouvre, entraîné par son propre poids et par le poids des déchets le cas échéant présents dans la cuve.The blocking part is then moved to its unlocking position releasing the opening lid, driven by its own weight and by the weight of the waste, if any, present in the tank.

Sur les figures on a utilisé les mêmes références pour désigner les mêmes éléments.In the figures, the same references have been used to designate the same elements.

Sur la figure 1a on peut voir, de côté, un exemple de bac roulant 1 selon la présente invention. Le même bac est représenté en vue frontale sur la figure 1b. Le bac 1 comporte une cuve 2 et un couvercle 3. Dans l'exemple non limitatif illustré le bac 1 comporte une paire de roues 4 disposée à sa base. Il est bien entendu que d'autres types de bacs roulants, notamment des bacs de grande capacité comportant par exemple quatre roues disposées à leurs bases, ne sortent pas du cadre de la présente invention.In Figure 1a we can see, from the side, an example of rolling bin 1 according to the present invention. The same container is shown in front view in FIG. 1b. The tank 1 comprises a tank 2 and a cover 3. In the nonlimiting example illustrated, the tank 1 comprises a pair of wheels 4 arranged at its base. It is understood that other types of wheeled bins, in particular large capacity bins comprising for example four wheels disposed at their bases, do not depart from the scope of the present invention.

Le bac 1 selon la présente invention comporte un dispositif de verrouillage 5 du couvercle 3 sur la cuve 2.The tank 1 according to the present invention comprises a device 5 for locking the cover 3 on the tank 2.

Sur la figure 2, on peut voir un exemple de réalisation du dispositif de verrouillage 5 selon la présente invention. Le dispositif 5 comporte une gâche 6 solidarisée avec le couvercle 3. Dans l'exemple illustré, la gâche 6 est boulonnée sur le couvercle 3. La gâche 6 pénètre à l'intérieur d'un verrou 7 monté sur la cuve.In FIG. 2, an exemplary embodiment of the locking device 5 according to the present invention can be seen. The device 5 comprises a keeper 6 secured to the cover 3. In the example illustrated, the keeper 6 is bolted to the cover 3. The keeper 6 penetrates inside a latch 7 mounted on the tank.

Sur la figure 3, on peut voir la gâche 6 pénétrant par une ouverture 8 à l'intérieur du verrou 7. La gâche 6 comporte à son extrémité un évidement 9 dans lequel pénètre un moyen de verrouillage, par exemple une saillie 10 d'un organe de manoeuvre tel qu'un loquet 11 tournant autour d'un axe 12. Le verrou 7 comporte une masse mobile ou battant 13 équipé de moyens de guidage coulissant en translation. Dans l'exemple illustré, le battant 13 comporte une rainure centrale 14 dans laquelle pénètrent deux pions 15 assurant son guidage en translation. La rainure centrale 14 est sensiblement verticale lorsque le bac roulant est dans sa position de repos (Fig. 3). Le battant 13 comporte à sa partie supérieure une- saillie 16 qui, dans cette position de repos, empêche la rotation du loquet 11, et par suite la libération de la gâche 6.In FIG. 3, one can see the keeper 6 penetrating through an opening 8 inside the lock 7. The keeper 6 has at its end a recess 9 into which penetrates a locking means, for example a projection 10 of a operating member such as a latch 11 rotating about an axis 12. The lock 7 comprises a movable or beating mass 13 fitted with guide means sliding in translation. In the example illustrated, the leaf 13 has a central groove 14 into which two pins penetrate 15 ensuring its guiding in translation. The central groove 14 is substantially vertical when the rolling container is in its rest position (Fig. 3). The wing 13 has at its upper part a projection 16 which, in this rest position, prevents rotation of the latch 11, and consequently the release of the keeper 6.

Le verrou 7 comporte une came 17 dont la rotation engendre la translation du battant 13, sensiblement verticalement dans la position de repos du bac roulant, de la position de la figure 3 à celle de la figure 4. Cette rotation est par exemple obtenue par la rotation d'une clef introduite par l'utilisateur du bac 1 dans une serrure 18.The latch 7 comprises a cam 17 whose rotation generates translation of the leaf 13, substantially vertically in the rest position of the wheeled bin, from the position of FIG. 3 to that of FIG. 4. This rotation is for example obtained by the rotation of a key inserted by the user of tray 1 in a lock 18.

L'ouverture du verrou 7 est illustrée sur la figure 4. Sous l'action de la clef (non représentée sur la figure) la came 17 tourne dans le sens de la flèche 19 et provoque la translation du battant 13 vers le haut dans le sens de la flèche 20. Dans cette position, la saillie 16 du battant 13 n'empêche plus la rotation du loquet 11 qui peut tourner autour de l'axe 12 dans le sens de la flèche 21. La saillie 10 du loquet 11 n'étant plus engagée dans l'évidement 9 de la gâche 6, celle-ci est libre de sortir du verrou 7 dans le sens de la flèche 22, et par suite, il est possible de soulever le couvercle.The opening of the latch 7 is illustrated in Figure 4. Under the action of the key (not shown in the figure) the cam 17 rotates in the direction of the arrow 19 and causes the leaf 13 to translate upward in the direction of arrow 20. In this position, the projection 16 of the leaf 13 no longer prevents the rotation of the latch 11 which can rotate around the axis 12 in the direction of the arrow 21. The projection 10 of the latch 11 does not being more engaged in the recess 9 of the keeper 6, the latter is free to come out of the latch 7 in the direction of the arrow 22, and as a result, it is possible to lift the cover.

Il est particulièrement avantageux que la rotation du loquet 11 soit provoquée automatiquement sous l'action de la clef faisant tourner la came 17. Dans l'exemple illustré, le battant 13 comporte une saillie inférieure 23, alors que le loquet 11 comporte une saillie inférieure 24. Lors de la translation du battant 13 provoquée par la rotation de la came 17, la saillie 23 vient en contact de la saillie 24. La surface de contact est par exemple sensiblement plane et orientée avec un angle α par rapport à l'horizontale, la pente allant de l'axe du battant vers le bord. En continuant sa translation, le battant 13 provoque la rotation du loquet 11 autour de l'axe 12 et ainsi une libération automatique de la gâche 6.It is particularly advantageous for the latch 11 to be automatically rotated under the action of the key turning the cam 17. In the example illustrated, the leaf 13 has a lower projection 23, while the latch 11 has a lower projection 24. During the translation of the leaf 13 caused by the rotation of the cam 17, the projection 23 comes into contact with the projection 24. The contact surface is for example substantially planar and oriented with an angle α relative to the horizontal. , the slope going from the axis of the leaf to the edge. By continuing its translation, the leaf 13 causes the latch 11 to rotate about the axis 12 and thus an automatic release of the keeper 6.

De plus, dans l'exemple illustré, la surface de contact entre l'évidement 9 de la gâche 6 et la saillie 10 du loquet 11, prend une forme sensiblement plane et une inclinaison ϑ par rapport à l'horizontale, la pente allant de l'axe de la gâche vers le bord. Ainsi, lorsque la saillie 16 du battant 13 n'empêche pas la rotation du loquet 11, une traction selon la flèche 22 sur la gâche 6, par l'intermédiaire du couvercle 3, provoque la rotation du loquet 11 autour de l'axe 12.In addition, in the example illustrated, the contact surface between the recess 9 of the keeper 6 and the projection 10 of the latch 11, takes a substantially planar shape and an inclination ϑ relative to the horizontal, the slope going from the striker axis towards the edge. Thus, when the projection 16 of the leaf 13 does not prevent the rotation of the latch 11, a pull along the arrow 22 on the keeper 6, through the cover 3, causes the rotation of the latch 11 about the axis 12 .

Dans l'exemple de réalisation représenté, le loquet 11 comporte une saillie inférieure 25 sensiblement symétrique à la saillie 24 par rapport à un plan vertical. La saillie 25 assure l'équilibre du loquet 11 et la saillie 10 du loquet 11 a tendance à se placer dans l'évidement 9 de la gâche 6.In the embodiment shown, the latch 11 has a lower projection 25 substantially symmetrical to the projection 24 relative to a vertical plane. The projection 25 ensures the balance of the latch 11 and the projection 10 of the latch 11 tends to be placed in the recess 9 of the keeper 6.

On se réfère maintenant aux figures 5, 6a et 6b.We now refer to Figures 5, 6a and 6b.

Pour passer dans la position inclinée de vidage illustrée à la figure 5, le bac roulant 1 est renversé. Cette opération est réalisée typiquement par un mécanisme de préhension et de basculement sur un camion de collecte mécanisée non représenté. Dès que l'axe vertical du bac roulant 1 a subi une rotation supérieure à 90°, et comme représenté sur la figure 6a, le battant 13, sous l'action de la pesanteur se déplace dans le sens de la flèche 26, provoquant la rotation du loquet 11 dans le sens de la flèche 27. La gâche 6 est libérée et se déplace dans le sens de la flèche 28 simultanément avec l'ouverture du couvercle 3 dans le sens de la flèche 29 (Figure 5).To pass into the inclined emptying position illustrated in FIG. 5, the rolling container 1 is overturned. This operation is typically carried out by a gripping and tilting mechanism on a mechanized collection truck not shown. As soon as the vertical axis of the wheeled bin 1 has undergone a rotation greater than 90 °, and as shown in FIG. 6a, the leaf 13, under the action of gravity, moves in the direction of arrow 26, causing the rotation of the latch 11 in the direction of the arrow 27. The keeper 6 is released and moves in the direction of the arrow 28 simultaneously with the opening of the cover 3 in the direction of the arrow 29 (Figure 5).

Comme on peut le voir sur la figure 6b, le battant 13 poursuit sa course dans le sens de la flèche 26 jusqu'à arriver en butée sur les pions 15 et/ou sur le boîtier du verrou 7. Lorsque la saillie 23 du battant 13 a dépassé la saillie 24 du loquet 11, celui-ci effectue une rotation dans le sens de la flèche 30, en sens inverse de celui permettant la libération de la gâche 6. Le loquet 11 retient par sa saillie 24 le battant 13 dans la position d'extrémité atteinte par ce dernier lors de son déplacement précédent dans le sens de la flèche 26.As can be seen in FIG. 6b, the leaf 13 continues its race in the direction of the arrow 26 until it comes into abutment on the pins 15 and / or on the lock housing 7. When the projection 23 of the leaf 13 has exceeded the projection 24 of the latch 11, the latter performs a rotation in the direction of the arrow 30, in the opposite direction to that allowing the release of the keeper 6. The latch 11 retains by its projection 24 the leaf 13 in the position end reached by the latter during its previous movement in the direction of arrow 26.

La figure 7 correspond à une position du bac roulant 1 lors de son mouvement de retour après vidage, le couvercle ouvert. Le battant 13 se trouve dans la position haute et sa saillie 23 repose sur la saillie 24 du loquet 11. Lorsque, lors de la fermeture du couvercle, la gâche 6 pénètre par l'ouverture 8 dans le sens de la flèche 31, un profil 32 de l'extrémité de la gâche 6 repousse le loquet 11 au niveau de la saillie supérieure 10. Le loquet 11 tourne autour de l'axe 12 dans le sens de la flèche 33. La saillie 24 du loquet 11 s'efface et permet la retombée du battant 13 dans le sens de la flèche 34 ainsi que la pénétration de la saillie 10 du loquet 11 dans l'évidement 9 de la gâche 6. Le dispositif retrouve sa position de départ de la figure 3 dans laquelle la saillie supérieure 16 du battant 13 empêche la rotation du loquet 11 verrouillant la gâche 6.Figure 7 corresponds to a position of the rolling bin 1 during its return movement after emptying, the cover open. The leaf 13 is in the high position and its projection 23 rests on the projection 24 of the latch 11. When, when the cover is closed, the keeper 6 enters through the opening 8 in the direction of the arrow 31, a profile 32 of the end of the strike 6 pushes the latch 11 at the upper projection 10. The latch 11 rotates around axis 12 in the direction of arrow 33. The projection 24 of latch 11 disappears and allows the leaf 13 to fall in the direction of arrow 34 as well as the penetration of projection 10 of latch 11 in the recess 9 of the keeper 6. The device returns to its starting position in FIG. 3 in which the upper projection 16 of the leaf 13 prevents rotation of the latch 11 locking the keeper 6.

L'invention s'applique principalement aux bacs roulants assurant la collecte des déchets industriels et/ou ménagers et notamment aux bacs roulants comportant une cuve, cloisonnée ou non, et un ou plusieurs couvercles permettant notamment la collecte sélective, le ou chaque couvercle pouvant être muni d'un dispositif de verrouillage tel que décrit ci-dessus.The invention applies mainly to wheeled bins ensuring the collection of industrial and / or household waste and in particular to wheeled bins comprising a tank, partitioned or not, and one or more lids allowing in particular the selective collection, the or each cover being able to be fitted with a locking device as described above.
