Description

La présente invention concerne un dispositif de sécurité notamment à l'égard des enfants pour bac de collecte de déchets.The present invention relates to a security device especially with regard to children for waste collection bin.

On connaít déjà des dispositifs de verrouillage de bacs pour la collecte de déchets, dans lesquels chaque utilisateur d'un bac dispose d'une clef qui lui permet, par l'intermédiaire d'une serrure, de verrouiller ou de déverrouiller à volonté le couvercle du bac lorsque ce dernier se trouve en position de repos.We already know locking devices of tanks for the waste collection, in which each user of a bin has a key which allows him, by means of a lock, to lock or unlock the lid of the tank as desired when this the latter is in the rest position.

Un tel dispositif se justifie notamment dans le cadre d'une facturation de la collecte des déchets, afin d'empêcher que des tiers n'utilisent des bacs auxquels ils n'auraient pas normalement accès, dans le but de se débarrasser de déchets à bon compte.Such a device is justified in particular in the context of a billing for waste collection, to prevent third parties do not use bins to which they would not normally have access, in the aim to get rid of garbage cheaply.

Dans ce type de dispositif, il suffit de disposer d'une clef pour ouvrir le bac si son couvercle est verrouillé.In this type of device, all you need is a key to open the container if its cover is locked.

Cependant, une fois le couvercle déverrouillé, n'importe quelle personne peut accéder à l'intérieur du bac.However, once the cover is unlocked, any no one can access the interior of the bin.

En particulier, des enfants peuvent être tentés de jouer avec le bac, et ainsi entrer en contact avec certains déchets, ce qui peut s'avérer très dangereux, d'autant plus que les systèmes de collecte sélective, qui se développent de plus en plus, incitent à rassembler dans un même bac des déchets de même nature, et notamment des déchets toxiques.In particular, children may be tempted to play with the bin, and thus come into contact with certain waste, which can be very dangerous, especially since the selective collection systems, which are growing more and more, prompting to gather in the same bin waste of the same kind, and in particular toxic waste.

On connaít, du document US-A-3 718 950 un dispositif de fixation pour lier de façon amovible deux éléments en plaque, par exemple un couvercle en forme de panneau à une cloison d'une boíte à fusibles d'un bus, d'un train ou analogue. Ce dispositif comporte une tige qui traverse les deux éléments enKnown from document US-A-3,718,950 a fixing device to removably link two plate elements, for example a panel-shaped cover to a bulkhead of a fuse box of a bus, train or the like. This device comprises a rod which crosses the two elements in

plaque, un bouton de manoeuvre de la tige et une pièce de retenue constituée par deux lames élastiques qui enserrent l'extrémité de la tige opposée au bouton de manoeuvre.plate, rod operating button and retainer consisting of two elastic blades which grip the end of the rod opposite the operating button.

Cette extrémité de la tige comporte deux paires d'épaulement espacées axialement et décalées angulairement d'un quart de tour.This end of the rod has two pairs of shoulders axially spaced and angularly offset by a quarter turn.

Chacune de ces paires d'épaulement peut servir d'appui aux lames élastiques pour retenir la tige axialement.Each of these pairs of shoulders can be used to support the blades elastic to retain the rod axially.

Lorsque l'on engage axialement l'extrémité de la tige entre les deux lames élastiques, l'une des deux paires d'épaulement se trouve en regard des lames élastiques, ce qui assure l'encliquetage de la tige dans la pièce de retenue.When the end of the rod is axially engaged between the two elastic blades, one of the two pairs of shoulders is in look of the elastic blades, which ensures the locking of the rod in the retainer.

Pour déverrouiller le tige, on le fait pivoter autour de son axe longitudinal en tournant son bouton de manoeuvre de manière à amener ses épaulements au-delà des surfaces d'appui des lames élastiques.To unlock the rod, rotate it around its axis longitudinal by turning its operating button so as to bring its shoulders beyond the bearing surfaces of the elastic blades.

Un ressort provoque alors l'éjection de le tige hors de le pièce de retenue.A spring then causes the rod to be ejected from the workpiece of restraint.

Le présente invention vise à fournir un dispositif de verrouillage du couvercle d'un bac qui permette à un adulte d'ouvrir ou de fermer le bac sans difficulté et qui interdise à un enfant, ou plus généralement à toute personne inapte à exercer une force suffisante, d'ouvrir ce bac.The present invention aims to provide a device for locking the lid of a container that allows an adult to open or close the bin without difficulty and which prohibits a child, or more generally any person unable to exert sufficient force, to open this bin.

La présente invention a pour objet un dispositif de verrouillage d'un bac pour la collecte de déchets, qui est caractérisé par le fait qu'il comporte, montés sur le couvercle du bac, une gâche et son bouton de manoeuvre, le bouton de manoeuvre étant libre de s'écarter de la gâche mais pouvant être maintenu à proximité de celle-ci par application d'une force, et, montée sur la cuve du bac, une pièce de retenue dans laquelle s'engage le gâche en position fermée du couvercle, la gâche étant mobile avec frottements entre une position de verrouillage dans laquelle elle est prisonnière de la pièce de retenue, et une position de déverrouillage dans laquelle elle peut se dégager de ladite pièce de retenue, la gâche et le bouton de manoeuvre comportant chacun des organes d'engrènement en forme de cames qui tendent à s'écarter mutuellement et à se désengrener lorsque le bouton de manoeuvre se déplace alors que la gâche demeure immobile en raison des frottements qui s'opposent à son déplacement.The present invention relates to a locking device a bin for the collection of waste, which is characterized by the fact that it comprises, mounted on the cover of the tank, a keeper and its button operation, the operation button being free to move away from the strike but can be kept close to it by applying a force, and, mounted on the tank of the tank, a retaining part in which engages the keeper in the closed position of the cover, the keeper being movable with friction between a locking position in which it is prisoner of the retainer, and an unlocking position in which it can disengage from said retainer, the keeper and the operating button comprising each of the engagement members in form of cams which tend to spread apart and disengage when the operating button moves while the keeper remains stationary because of the friction which opposes its displacement.

En d'autres termes, selon l'invention, les organes d'engrènement qui se trouvent sur le bouton de manoeuvre d'une part et sur la gâche d'autre part, ne demeurent engrenés que si l'on exerce une force suffisante sur le bouton de manoeuvre pour l'empêcher de s'écarter de la gâche.In other words, according to the invention, the organs which are on the operating button on the one hand and on the keeper, on the other hand, remain engaged only if one exerts sufficient force on the operating button to prevent it from moving away from the keeper.

Dans ce cas seulement, l'actionnement du bouton de manoeuvre entraíne le déplacement de la gâche.In this case only, actuation of the operating button causes the strike to move.

Par conséquent, seules des personnes aptes à exercer une force suffisante sur le bouton de manoeuvre pendant son actionnement peuvent verrouiller ou déverrouiller le couvercle du conteneur.Therefore, only persons capable of applying force sufficient on the operating button during its actuation can lock or unlock the container lid.

En revanche, des personnes inaptes à exercer une telle force sur le bouton de manoeuvre, notamment les enfants, ne peuvent que manoeuvrer le bouton de manoeuvre, sans provoquer le déplacement de la gâche.On the other hand, persons incapable of exerting such force on the operating button, especially children, can only operate the operating button, without causing the movement of the strike.

Dans un mode de réalisation préféré de l'invention, le bouton de manoeuvre et la gâche sont montés pivotants autour d'un même axe, le bouton de manoeuvre pouvant s'écarter axialement de la gâche.In a preferred embodiment of the invention, the button maneuver and the keeper are pivotally mounted about the same axis, the operating button being able to deviate axially from the keeper.

Selon une variante préférée, la gâche comporte un moyen de rappel qui la replace systématiquement en position de verrouillage.According to a preferred variant, the keeper comprises a means of reminder which systematically returns it to the locked position.

Dans le but de mieux faire comprendre l'invention, on va en décrire maintenant un mode de réalisation donné à titre d'exemple non limitatif en référence au dessin annexé dans lequel :

  • la figure 1 est une vue en coupe partielle de la partie supérieure d'un bac pour la collecte de déchets, muni d'un dispositif de sécurité selon l'invention, représenté de façon schématique,
  • la figure 2 représente schématiquement le dispositif de la figure 1 manoeuvré sans application d'aucune force sur le bouton de manoeuvre,
  • la figure 3 est une vue analogue à celle de la figure 2 représentant le dispositif manoeuvré avec application d'une force sur le bouton de manoeuvre,
  • la figure 4 est une vue éclatée et en perspective d'un dispositif selon un mode de réalisation de l'invention,
  • la figure 5 est une vue en coupe partielle du dispositif de la figure 4, et
  • les figures 6A et 6B sont des vues en coupe selon VI-VI de la figure 5, représentant la gâche engagée dans la pièce de retenue, respectivement en position de déverrouillage et en position de verrouillage.
In order to better understand the invention, we will now describe an embodiment given by way of non-limiting example with reference to the accompanying drawing in which:
  • FIG. 1 is a partial sectional view of the upper part of a bin for collecting waste, fitted with a safety device according to the invention, shown diagrammatically,
  • FIG. 2 schematically represents the device of FIG. 1 operated without applying any force to the operating button,
  • FIG. 3 is a view similar to that of FIG. 2 showing the device maneuvered with the application of a force on the operating button,
  • FIG. 4 is an exploded perspective view of a device according to an embodiment of the invention,
  • FIG. 5 is a partial sectional view of the device of FIG. 4, and
  • Figures 6A and 6B are sectional views along VI-VI of Figure 5, showing the keeper engaged in the retaining part, respectively in the unlocked position and in the locked position.

Sur la figure 1, on a représenté la partie supérieure d'un bac comportant une cuve 1 et un couvercle 2 muni d'une poignée 3.In Figure 1, there is shown the upper part of a tank comprising a tank 1 and a cover 2 provided with a handle 3.

Une gâche 4 et son bouton de manoeuvre 5 sont montés sur le couvercle 2 dans un dégagement 6 du couvercle délimité inférieurement par une portion de paroi plane 7 de ce dernier.A keeper 4 and its operating button 5 are mounted on the cover 2 in a clearance 6 of the cover delimited below by a flat wall portion 7 of the latter.

La gâche 4 traverse un orifice de la paroi 7 et repose sur cette dernière par une collerette 8, deux pattes de retenue élastiques 9 à débattement radial, solidaires de la gâche 4, étant situées de l'autre côté de la paroi 7 pour plaquer la gâche contre ladite paroi.The keeper 4 passes through an orifice in the wall 7 and rests on the latter by a flange 8, two retaining tabs elastic 9 with radial clearance, integral with the keeper 4, being located on the other side of the wall 7 to press the strike against said wall.

Les pattes de retenue 9 et la collerette 8 pincent la paroi 7 et produisent, en cas de pivotement de la gâche, des frottements qui s'opposent à ce pivotement.The retaining tabs 9 and the flange 8 pinch the wall 7 and produce, in the event of pivoting of the strike, frictions which oppose this pivoting.

La gâche 4 est ainsi montée pivotante avec frottements sur le couvercle 2.The keeper 4 is thus pivotally mounted with friction on the cover 2.

Le bouton de manoeuvre est monté sur la gâche 4 par des moyens de fixation à débattement axial non représentés sur cette figure 1.The operating button is mounted on the keeper 4 by fixing means with axial movement not shown on this figure 1.

A sa partie inférieure, la gâche comporte deux échancrures 10 opposées dans lesquelles peuvent s'engager deux lames élastiques 11 d'une pièce de retenue 12 solidaire de la partie supérieure de la cuve 1.At its lower part, the keeper has two notches 10 opposite in which two elastic blades can engage 11 a retaining piece 12 secured to the upper part of the tank 1.

On comprend que, selon la position angulaire de la gâche 4, les lames 11 prennent appui chacune soit contre le fond d'une échancrure 10, la gâche 4 se trouvant alors en position de verrouillage, comme représenté sur la figure 1, soit contre une génératrice de la gâche 4, la gâche se trouvant alors en position de déverrouillage, comme représenté à la figure 3.We understand that, depending on the angular position of the keeper 4, the blades 11 each bear either against the bottom of a notch 10, the keeper 4 then being in the position of lock, as shown in Figure 1, either against a generator of the keeper 4, the keeper then being in the position of unlocking, as shown in figure 3.

Conformément à l'invention, le bouton de manoeuvre 5 et la gâche 4 comportent des organes d'engrènement en forme de cames 13a, 13b qui ont tendance à s'écarter mutuellement lorsque l'on fait pivoter le bouton de manoeuvre, tandis que la gâche reste immobile en raison des frottements exercés sur la paroi plane 7 par la collerette 8 et les pattes de retenue 9.According to the invention, the operating button 5 and the keeper 4 have gear-like engagement members cams 13a, 13b which tend to spread apart when one rotates the operating knob, while the strike remains immobile due to the friction exerted on the flat wall 7 by the flange 8 and the retaining tabs 9.

Si l'on n'exerce aucune force ou une force insuffisante sur le bouton de manoeuvre 5, lorsque l'on tourne le bouton de manoeuvre, les organes d'engrènement 13a, 13b s'écartent en repoussant le bouton de manoeuvre et se désengrènent, la gâche restant alors dans sa position initiale.If no or insufficient force is exerted on the operating button 5, when the operating button is turned, the engagement members 13a, 13b move apart by pushing the button maneuver and disengage, the keeper then remaining in its initial position.

Si, en revanche, on exerce sur le bouton de manoeuvre 5 une force dirigée vers le bas, suffisante pour le maintenir à proximité de la gâche, comme indiqué par la flèche 14 sur la figure 3, lorsque l'on tourne le bouton de manoeuvre, les organes d'engrènement 13a, 13b demeurent engrenés et la gâche pivote avec le bouton de manoeuvre.If, on the other hand, there is an exercise on the operating button 5 downward force sufficient to keep it close of the keeper, as indicated by the arrow 14 in FIG. 3, when we turn the operating knob, the organs 13a, 13b remain engaged and the keeper pivots with the operating button.

On peut alors positionner la gâche en position de déverrouillage et déverrouiller le couvercle du bac, comme représenté à la figure 3.We can then position the strike in position unlocking and unlocking the tank cover, as shown in Figure 3.

En ajustant convenablement différents paramètres du dispositif, notamment l'angle d'inclinaison  des organes d'engrènement, et le moment résistant de la gâche, on peut faire varier la force qu'il est nécessaire d'appliquer sur le bouton de manoeuvre pour faire pivoter la gâche.By suitably adjusting different parameters of the device, in particular the angle of inclination  of the members of engagement, and the resistant moment of the strike, we can do vary the force which it is necessary to apply on the button maneuver to rotate the strike.

En première approximation, cette force peut être considérée comme proportionnelle au moment résistant de la gâche, et à la fonction cotangente de l'angle d'inclinaison  des organes d'engrènement 13a, 13b.As a first approximation, this force can be considered as proportional to the resistant moment of the strike, and to the cotangent function of the tilt angle  of the organs meshing 13a, 13b.

En d'autres termes, plus le moment résistant de la gâche est élevé, plus la force à exercer sur le bouton de manoeuvre est grande. De même, plus l'angle  défini ci-dessus est faible, plus la force à exercer sur le bouton de manoeuvre est élevée. In other words, the higher the resistance moment of the strike the higher, the greater the force to be exerted on the operating button. Similarly, the smaller the angle  defined above, the more the force exerted on the operating button is high.

Le choix de tels paramètres permet de limiter les possibilités d'actionnement de la gâche aux seules personnes aptes à exercer une force suffisante, et d'exclure ainsi les enfants.The choice of such parameters limits the possibilities actuation of the strike only to persons capable of exercising a sufficient force, and thus exclude children.

La figure 4 représente d'une manière non schématique un dispositif selon un deuxième mode de réalisation de l'invention, dont les parties fonctionnellement équivalentes à celles décrites précédemment sont repérées par les mêmes chiffres de référence que sur les figures 1 à 3.Figure 4 shows in a non-schematic way a device according to a second embodiment of the invention, the parts functionally equivalent to those described above are identified by the same reference numbers as in the figures 1 to 3.

Les organes d'engrènement sont constitués, sur la gâche 4, par des épaulements rapportés 13a, et, sur le bouton de manoeuvre 5, par des parties creuses 13b issues de moulage.The engagement members are constituted, on the keeper 4, by added shoulders 13a, and, on the operating button 5, by hollow parts 13b from molding.

Comme on le voit sur la figure 5, le bouton de manoeuvre 5 est solidarisé à la gâche 4 par un pion 15 qui pénètre dans un logement 16 du bouton de manoeuvre, permettant le débattement axial de ce dernier par rapport à la gâche.As seen in Figure 5, the operating button 5 is secured to strike 4 by a pin 15 which enters a housing 16 of the operating button, allowing axial movement of the latter compared to the striker.

A cet effet, le logement 16 est notamment délimité par deux lamelles 17 munies chacune d'une nervure d'arrêt 18 qui empêche le pion 15 de quitter le logement 16.To this end, the housing 16 is notably delimited by two slats 17 each provided with a stop rib 18 which prevents the pawn 15 to leave the accommodation 16.

Le corps de la gâche est muni de nervures 19 parallèles à l'axe de la gâche, qui divisent ce corps en quatre quartiers. Chacun de ces quartiers constitue une échancrure 10 dans laquelle peut pénétrer une lame élastique 11 de la pièce de retenue.The body of the keeper is provided with ribs 19 parallel to the axis of the striker, which divides this body into four quarters. Each of these neighborhoods constitutes a notch 10 in which can penetrate an elastic blade 11 of the retaining part.

Un disque 20 se situe dans la partie médiane du corps de la gâche et constitue une surface sur laquelle les lames élastiques 11 de la pièce de retenue 12 prennent appui lorsque la gâche est en position verrouillée, comme on le voit sur la figure 6B.A disc 20 is located in the middle part of the body of the striker and constitutes a surface on which the elastic blades 11 of the retaining part 12 bear when the keeper is in locked position, as seen in Figure 6B.

Dans le mode de réalisation illustré, la pièce de retenue 12 constitue un moyen de rappel qui replace systématiquement la gâche en position de verrouillage lorsque l'on referme le couvercle.In the illustrated embodiment, the retaining piece 12 is a reminder that systematically replaces the keeper locking position when the cover is closed.

En effet, la position de déverrouillage de la gâche, représentée à la figure 6A, est une position instable, du fait de l'étroitesse des nervures 19 sur lesquelles les lames élastiques 11 exercent chacune une force qui a de très faibles chances, lors de la pénétration de la gâche dans la pièce de retenue, d'être dirigée rigoureusement dans l'axe de la gâche.Indeed, the unlocking position of the striker, shown in Figure 6A, is an unstable position, due to the narrowness of the ribs 19 on which the elastic blades 11 each exert a force which has very low chances, when penetration of the keeper in the retaining part, to be directed strictly in line with the strike.

Dans ces conditions, les forces exercées par les lames élastiques forment un couple de rotation qui fait pivoter la gâche pour la mettre dans sa position de verrouillage, représentée à la figure 6B.Under these conditions, the forces exerted by the blades elastics form a torque that turns the keeper to put it in its locked position, shown in the Figure 6B.

Il est donc nécessaire, pour ouvrir le bac, de tirer son couvercle pour dégager la gâche de la pièce de retenue au moment précis où la gâche passe par sa position de déverrouillage.It is therefore necessary, to open the bin, to pull its cover to release the keeper from the retainer when precise where the strike goes through its unlocking position.

A la fermeture du couvercle, la gâche reprend automatiquement sa position de verrouillage.When the lid is closed, the strike automatically resumes its locking position.

Ainsi, le dispositif illustré offre une excellente garantie de sécurité.Thus, the device illustrated offers an excellent guarantee of security.

Il est bien entendu que le mode de réalisation qui vient d'être décrit ne présente aucun caractère limitatif, et qu'il pourra recevoir toutes modifications désirables sans sortir pour cela du cadre de l'invention comme definie dans les revendications qui suivent.It is understood that the embodiment which comes to be described has no limiting character, and that it may receive any desirable changes without leaving the scope of the invention as defined in the claims which follow.
