Description

Dispositif mécanique de sécurité pour la transmission de courant électrique Mechanical safety device for the transmission of electric current
La présente invention concerne un dispositif mécanique de sécurité qui permet la transmission du courant électrique. Ce dispositif est présent entre deux prises électriques, l'une mobile, l'autre murale et fixe. Le dispositif sert donc au raccordement et à la transmission entre ces deux prises.The present invention relates to a mechanical safety device which allows the transmission of electric current. This device is present between two electrical sockets, one mobile, the other wall and fixed. The device is therefore used for connection and transmission between these two sockets.
Le dispositif mécanique de sécurité a pour objet essentiel d'utiliser la traction exercée sur lesdites prises comme signal de séparation de ces prises, ceci afin de ne pas détériorer les installations électriques.The essential object of the mechanical safety device is to use the traction exerted on said sockets as a signal for separation of these sockets, in order not to damage the electrical installations.
Actuellement, lorsque la longueur du cordon d'alimentation d'un appareil électrique est très longue, ce qui est souvent le cas dans les hôtels, les locaux commerciaux ou administratifs, l'utilisateur de l'appareil ne connaît jamais la longueur de cordon restante. S'il vient à ne plus avoir de longueur disponible, soit le cordon a été complètement utilisé, soit ledit cordon est emmêlé et empêche l'utilisation de la longueur totale du cordon. Dans les deux cas de figure, l'utilisateur a généralement tendance à tirer en force sur le cordon, ce qui peut permettre de gagner une certaine longueur de cordon. Dans le cas où la longueur de cordon disponible est nulle, une traction effectuée de biais, c'est-à-dire non dans l'axe longitudinal de la prise murale fixe, peut détériorer cette prise murale. Il peut s'ensuivre que les fusibles sautent, ce qui peut être très gênant dans les hôtels ou autres lieux où il y a de la clientèle.Currently, when the length of the power cord of an electrical appliance is very long, which is often the case in hotels, commercial or administrative premises, the user of the appliance never knows the remaining length of cord . If it runs out of available length, either the cord has been completely used up, or the said cord is tangled and prevents the use of the full length of the cord. In both cases, the user generally tends to pull forcefully on the cord, which can allow a certain length of cord to be saved. In the case where the available cord length is zero, a pull carried out at an angle, that is to say not in the longitudinal axis of the fixed wall socket, can damage this wall socket. It can follow that the fuses blow, which can be very annoying in hotels or other places where there are customers.
L 'état de la technique peut être défini par le document EP-A- 0.417.892 qui propose un mécanisme équipé d 'une paire de connecteurs électriques pouvant s ' accoupler, pour les verrouiller ensemble lorsqu ' ils ont été accouplés et pour plus tard éjecter l 'un hors de l ' autre. Le mécanisme, qui a la même largeur étroite que les connecteurs seuls , comprend une paire de dispositifs de verrouillage/ éjection ou éléments montés pivotants aux extrémités opposées d 'un premier connecteur. Le second connecteur comprend une enveloppe de protection dotée d 'ouvertures à proximité de ses extrémités opposées qui logent les parties internes des éléments de verrouillage. La partie interne de chaque élément de verrouillage comprend un verrou qui est logé dans une fente évidée de l ' enveloppe de protection, et s 'étend à partir d 'une ouverture de l ' enveloppe de protection en position de verrouillage. Chaque élément de verrouillage comprend aussi une partie d 'éjection qui appuie sur la base du second connecteur lorsque l 'élément de verrouillage pivote vers sa position d ' éjection, pour éjecter le premier connecteur hors du second.The state of the art can be defined by the document EP-A-0.417.892 which proposes a mechanism equipped with a pair of electrical connectors which can be coupled, to lock them together when they have been coupled and later to eject one from the other. The mechanism, which has the same narrow width as the connectors alone, comprises a pair of locking / ejection devices or pivotally mounted elements at opposite ends of a first connector. The second connector includes a protective cover having openings near its opposite ends which accommodate the internal parts of the locking elements. The internal part of each locking element comprises a lock which is housed in a recessed slot in the protective casing, and extends from an opening of the protective casing in the locked position. Each locking member also includes an ejection portion which presses on the base of the second connector when the locking member pivots to its ejection position, to eject the first connector from the second.
Dans ce cas, l'éjection des connecteurs est due au choix de l'utilisateur et ne prévient pas l'arrachement d'une prise murale.In this case, the ejection of the connectors is due to the choice of the user and does not prevent the tearing of a wall outlet.
Le document FR-A-2.626. 722 consiste en la réalisation d 'un dispositif de prise de courant avec coupe-circuit verrouillable incorporé. Il est constitué par la combinaison d 'une prise avec fiches formant socle incorporé à une autre prise superposée comportant un interrupteur commandé par une clé amovible. Il est destiné à permettre de laisser les fiches de la prise branchées sur le secteur, tout en coupant le circuit avec fermeture de sûreté.Document FR-A-2.626. 722 consists of the realization of a socket outlet with incorporated lockable circuit breaker. It consists of the combination of a socket with plugs forming a base incorporated into another superimposed socket comprising a switch controlled by a removable key. It is intended to allow the plugs to be left plugged into the mains, while cutting the circuit with safety closing.
Ce document propose une sécurité électrique d'une prise de courant mobile d'un appareil électrique qui peut par conséquent rester branché sur une prise murale. Il n'y a pas ici de sécurité mécanique contre l'arrachement.This document proposes electrical safety for a mobile socket outlet of an electrical appliance which can therefore remain plugged into a wall socket. There is no mechanical security here against pulling out.
Le document FR-A-2.482. 793 a pour objet un électro- aimant commandé à distance, est logé et positionné dans le corps ou enveloppe protectrice de la fiche (ou de la partie femelle) , 1 'armature mobile dudit électro- aimant coopérant avec un doigt d 'éjection monté coulissant dans le corps de la fiche ou de la partie femelle, en étant susceptible d ' en déborder notamment entre les broches (ou les douilles) , ladite armature étant combinée avec le doigt pour autoriser, d 'une part , son verrouillage en position escamotée et, d ' autre part, sa détente brusque pour déborder du corps de la fiche (ou de la partie femelle) et prendre appui sur une partie appropriée de la partie femelle (ou de la fiche) en vue de l ' éjection de la fiche mâle lorsque ledit électro- aimant est excité. Dans ce cas, il y a bien éjection d'une prise de courant mobile par rapport à une prise murale fixe. Néanmoins, l'éjection est due à un système électro-mécanique qui fonctionne lorsqu'il est activé par l'utilisateur. Il n'évite pas l'arrachement d'une prise murale fixe provoqué par une forte traction sur le cordon électrique d'alimentation solidaire d'une prise mobile d'un appareil électrique, la prise mobile coopérant avec la prise murale fixe.Document FR-A-2.482. 793 relates to a remotely controlled electromagnet, is housed and positioned in the body or protective casing of the plug (or of the female part), the movable armature of said electromagnet cooperating with a sliding mounted ejection finger in the body of the plug or of the female part, being capable of overflowing in particular between the pins (or the sockets), said armature being combined with the finger to allow, on the one hand, its locking in the retracted position and , on the other hand, its sudden relaxation to overflow the body of the plug (or of the female part) and rest on an appropriate part of the female part (or of the plug) for the purpose of ejecting the male plug when said electromagnet is excited. In this case, there is indeed ejection of a mobile outlet from a fixed wall outlet. However, the ejection is due to an electro-mechanical system that works when activated by the user. It does not prevent the tearing of a fixed wall socket caused by a strong pull on the electric supply cord secured to a mobile socket of an electrical appliance, the mobile socket cooperating with the fixed wall socket.
Le document EP-A-0.586.359 concerne un dispositif qui assure automatiquement le désengagement d ' une fiche électrique par rapport à une prise correspondante, lorsqu ' un effort appliqué sur celle-ci ou l ' un des éléments, par exemple le câble, dépasse une valeur minimum donnée. Il comprend un élément mobile entre deux positions : dans la première, l 'élément et plus particulièrement un cliquet maintient l ' élément de commande et les organes de poussée , qui y sont associés , à 1 ' encontre de 1 ' action de moyens élastiques ; dans la seconde, il libère l 'élément de commande à l ' action desditε moyens élastiques qui alors assurent un déplacement relatif entre la fiche et la prise pour les désaccoupler . Ce mécanisme de sécurité permet d'éviter qu'une prise soit enfichée inopinément dans une prise murale normalisée, comportant un rebord périphérique. Il y a un mécanisme d'éjection qui ne peut fonctionner que par rotation d'une poignée de commande par rapport à un boîtier. Ce mouvement peut être dangereux ; de plus, la largeur de la prise mobile de courant est très importante, ce qui crée un bras de levier pouvant facilement arracher ladite prise par rapport à une prise murale. De plus, si la prise mobile est très solidement enfichée dans la prise murale, les moyens d'éjection seront dans l'impossibilité de désolidariser les deux fiches.The document EP-A-0.586.359 relates to a device which automatically ensures the disengagement of an electrical plug with respect to a corresponding socket, when a force applied to it or to one of the elements, for example the cable, exceeds a given minimum value. It comprises an element movable between two positions: in the first, the element and more particularly a pawl holds the control element and the thrust members, which are associated therewith, against the action of elastic means; in the second, it releases the control element to the action of said elastic means which then ensure a relative movement between the plug and the socket in order to decouple them. This safety mechanism makes it possible to prevent a plug from being unexpectedly plugged into a standardized wall outlet, comprising a peripheral flange. There is an ejection mechanism that can only work by rotating a control handle relative to a housing. This movement can be dangerous; in addition, the width of the movable current outlet is very large, which creates a lever arm which can easily tear off said outlet relative to a wall outlet. In addition, if the mobile socket is very securely inserted in the wall socket, the ejection means will be unable to separate the two plugs.
Le document GB-A-2.248.349 propose un connecteur comprenant un premier cadre de connexion ayant des secondes bornes métalliques, un second cadre de connexion ayant des secondes bornes métalliques, solidarisables avec les premières bornes, et un appareil de blocage pour l ' accrochage réciproque des cadres. Le premier cadre comprend un ressort coulissant recevant un élément pour contenir la force répulsive du ressort. Quand lès cadres sont solidarisés, le second cadre glisse à l ' encontre de l 'élément contenant le ressort jusqu 'à ce qu 'un cliquet de solidariεation, qu 'il porte, s 'engage avec une partie du premier cadre. Le ressort est alors compressé, alors que l 'élément empêche l 'action dudit ressort sur le second cadre qui reste solidarisé avec ledit premier cadre. Une pression sur un Jbras porté par ledit second cadre délivre le cliquet de solidarisation, ce qui permet au ressort de désolidariser les cadres l 'un de l 'autre.The document GB-A-2.248.349 proposes a connector comprising a first connection frame having second metal terminals, a second connection frame having second metal terminals, which can be joined to the first terminals, and a blocking device for the reciprocal attachment of the frames. The first frame includes a sliding spring receiving an element to contain the repulsive force of the spring. When the frames are joined, the second frame slides against the element containing the spring until a locking pawl, which it carries, engages with part of the first frame. The spring is then compressed, while the element prevents the action of said spring on the second frame which remains secured to said first frame. Pressure on a Jbras carried by said second frame delivers the securing pawl, which allows the spring to separate the frames from one another.
A l'instar du précédent document, la détérioration d'une prise murale est à envisager car le connecteur ne s'oriente pas en fonction de la traction qu'il subit. De plus, cette traction est une action volontaire et non pas accidentelle. Enfin, si l'enfichage est très solide, le ressort n'ayant aucun recul ni aucune amplitude vis-à-vis de la connexion entre les cadres ne pourra permettre la désolidarisation.Like the previous document, the deterioration of a wall outlet is to be considered because the connector does not orient itself according to the traction which it undergoes. In addition, this traction is a voluntary action and not accidental. Finally, if the plug-in is very solid, the spring having no recoil or any amplitude vis-à-vis the connection between the frames will not allow separation.
La présente invention répond à tous ces problèmes en permettant l'orientation du dispositif mécanique de sécurité et en proposant un "effet marteau" qui facilite la désolidarisation d'une prise mobile par rapport à une prise murale.The present invention responds to all these problems by allowing the orientation of the mechanical safety device and by proposing a "hammer effect" which facilitates the separation of a mobile outlet from a wall outlet.
A cet effet, la présente invention propose un dispositif mécanique de sécurité pour la transmission de courant électrique, et pour le raccordement entre une prise électrique mobile, d'un appareil électrique, d'une part, et une prise électrique murale fixe ou une rallonge, d'autre part, caractérisé par le fait qu'il est constitué d'un boîtier de raccordement équipé d'un cordon souple d'alimentation dont une extrémité est pourvue d'une prise de raccordement sur la prise murale et dont l'autre extrémité alimente la prise de jonction dudit dispositif de sécurité avec la prise mobile, ledit dispositif est pourvu d'un mécanisme d'éjection, de la prise électrique mobile, qui est actionné sous l'action d'une traction exercée sur ledit dispositif de sécurité, ledit mécanisme d'éjection est situé au niveau de la prise de jonction"du dispositif de sécurité.To this end, the present invention provides a mechanical safety device for the transmission of electric current, and for the connection between a mobile electrical outlet, of an electrical appliance, on the one hand, and a fixed electrical outlet or an extension cord. , on the other hand, characterized in that it consists of a connection box equipped with a flexible power cord, one end of which is provided with a connection socket on the wall socket and the other of which end supplies the junction socket of said safety device with the mobile socket, said device is provided with an ejection mechanism, of the mobile electrical socket, which is actuated by the action of a traction exerted on said safety device , said ejection mechanism is located at the junction socket " of the safety device.
Le mécanisme d'éjection comporte :The ejection mechanism includes:
- des moyens d'armement,- means of arming,
- des moyens d'éjection proprement dits, et - des moyens de désarmement.- actual ejection means, and - means of disarmament.
Le mécanisme d'éjection est constitué essentiellement par un chariot mobile monté à l'encontre d'au moins un ressort constituant les moyens d'éjection, le chariot étant mobile entre une position où chaque ressort est compressé suite à la mise en oeuvre des moyens d'armement, et une position où chaque ressort est décompressé suite à la mise en oeuvre des moyens de désarmement.The ejection mechanism consists essentially of a mobile carriage mounted against at least one spring constituting the ejection means, the carriage being mobile between a position where each spring is compressed following the implementation of the means arming, and a position where each spring is decompressed following the implementation of the disarming means.
Chaque ressort est monté coaxialement autour d'une colonne télescopique dont les extrémités sont solidaires, d'une part, du chariot mobile et, d'autre part, d'une plaque support.Each spring is mounted coaxially around a telescopic column, the ends of which are integral, on the one hand, with the mobile carriage and, on the other hand, with a support plate.
Le chariot comporte au moins une patte ayant des surfaces de contact pour les moyens d'armement et de désarmement.The carriage comprises at least one tab having contact surfaces for the arming and disarming means.
Selon un mode de réalisation, le chariot est solidaire d'un doigt d'éjection situé, lorsque le dispositif raccorde une prise mobile et une prise murale fixe, entre la prise électrique mobile et la prise de jonction, le doigt d'éjection étant au contact de ladite prise de jonction, en position armée, et éloignée de la prise de j-onction en position désarmée. Selon un autre mode de réalisation, le chariot coopère avec un doigt d'éjection situé, lorsque le dispositif raccorde une prise mobile et une prise murale fixe, entre la prise électrique mobile et la prise de jonction, le doigt d'éjection étant au contact ou en translation longitudinale aux abords de ladite prise de jonction, en position armée, et éloignée de la prise de jonction en position désarmée, de sorte que le chariot vient frapper le doigt d'éjection lors du désarmement du dispositif mécanique de sécurité, ce qui facilite l'éjection de la prise mobile. Quel que soit le mode de réalisation, le doigt d'éjection est formé, entre autres, d'un anneau de contact avec la prise mobile dont les formes sont complémentaires et facilitent l'éjection de ladite prise mobile.According to one embodiment, the carriage is integral with an ejection finger located, when the device connects a mobile outlet and a fixed wall outlet, between the mobile electrical outlet and the junction outlet, the ejection finger being at contact of said junction socket, in the armed position, and distant from the junction socket in the disarmed position.

Whatever the embodiment, the ejection finger is formed, inter alia, from a contact ring with the mobile socket, the shapes of which are complementary and facilitate the ejection of said mobile socket.
Les moyens d'armement sont constitués par un bras d'armement solidaire d'au moins une came pouvant pivoter autour d'au moins un axe de rotation coopérant avec la carcasse extérieure du boîtier de raccordement, la came actionnant en translation le chariot à l'encontre du ou des ressorts.The arming means are constituted by an arming arm secured to at least one cam which can pivot around at least one axis of rotation cooperating with the external carcass of the connection box, the cam actuating the carriage in translation. against the springs.

La présente invention concerne un dispositif mécanique de sécurité 1 bien représenté sur les figures 1 à 4.The present invention relates to a mechanical safety device 1 well represented in FIGS. 1 to 4.
Ce dispositif 1 a pour propriété de permettre la transmission du courant électrique entre une prise électrique mobile 2 pouvant être enfichée selon FI sur ledit dispositif 1, comme cela est bien représenté sur la figure 1. Cette prise électrique mobile 2 provenant d'un appareil électrique tel que, par exemple, un aspirateur et d'autre part, une prise électrique murale fixe 3 qui peut recevoir par enfichage le dispositif mécanique de sécuritéThis device 1 has the property of allowing the transmission of electric current between a mobile electrical outlet 2 which can be plugged in according to FI on said device 1, as is well represented in FIG. 1. This mobile electrical outlet 2 coming from an electrical appliance such as, for example, a vacuum cleaner and on the other hand, a fixed electrical outlet 3 which can receive by plugging in the mechanical safety device
1 selon F2 de la figure 1.1 according to F2 in Figure 1.
Dans le principe, le dispositif mécanique de sécurité 1 vient. s'interposer dans une liaison classique entre une prise mâle et une prise femelle. Ce dispositif de sécurité 1 a pour objet essentiel d'être sensible à la traction exercée selon F3 comme on le voit bien sur les figures 2 et 4.In principle, the mechanical safety device 1 comes. to intervene in a classic connection between a male plug and a female plug. The essential object of this safety device 1 is to be sensitive to the traction exerted according to F3 as can be seen clearly in FIGS. 2 and 4.
Cette traction est transmise selon F4 par l'intermédiaire du dispositif mécanique de sécurité 1 qui comprend un cordon d'alimentation électrique 5.This traction is transmitted according to F4 via the mechanical safety device 1 which comprises an electrical supply cord 5.
Comme on le voit bien aux figures 1 à 3, ce cordon 5 est souple. Il permet, comme cela est représenté sur la figure 4, une orientation de l'ensemble du dispositif 1 selon l'endroit où est exercée la traction F3. Lorsque la traction F3 dépasse un certain seuil, le dispositif 1 va permettre l'éjection de la prise électrique mobileAs can be seen in Figures 1 to 3, this cord 5 is flexible. It allows, as shown in Figure 4, an orientation of the entire device 1 depending on where the traction F3 is exerted. When the traction F3 exceeds a certain threshold, the device 1 will allow the mobile electrical outlet to be ejected
2 selon la flèche F5 de la figure 3.2 according to arrow F5 in FIG. 3.
Le seuil de sensibilité est bien entendu calculé pour permettre l'éjection de la prise mobile 2 avant que la traction ait détérioré la prise murale 3.The sensitivity threshold is of course calculated to allow the mobile outlet 2 to be ejected before the traction has damaged the wall outlet 3.
La sécurité est donc d'empêcher la détérioration de la prise murale 3, et ainsi d'éviter tous problèmes électriques inhérents à la destruction d'une prise murale.Safety is therefore to prevent deterioration of the wall socket 3, and thus to avoid any electrical problems inherent in the destruction of a wall socket.
Le dispositif mécanique de sécurité 1 est essentiellement constitué d'un boîtier de raccordement 4 équipé d'un cordon souple d'alimentation 5.The mechanical safety device 1 is essentially consisting of a connection box 4 equipped with a flexible power cord 5.
Ce cordon d'alimentation souple 5 possède deux extrémités, 1'une pourvue d'une prise de raccordement 6 qui est destinée à coopérer avec la prise murale 3, et l'autre qui alimente la prise de jonction 7, portée par le dispositif de sécurité 1.This flexible power cord 5 has two ends, one provided with a connection socket 6 which is intended to cooperate with the wall socket 3, and the other which supplies the connection socket 7, carried by the device for security 1.
Cette prise de jonction 7 est bien visible sur les figuresThis junction socket 7 is clearly visible in the figures
1 à 3. C'est elle qui coopère avec la prise mobile 2 d'un appareil électrique. Le boîtier de raccordement 4 est pourvu d'un mécanisme d'éjection 8 qui est bien représenté sur les figures 5 à 8, puisque la carcasse extérieure 20 n'est pas visible sur celles-ci.1 to 3. She is the one who cooperates with the mobile socket 2 of an electrical appliance. The connection box 4 is provided with an ejection mechanism 8 which is well represented in FIGS. 5 to 8, since the external carcass 20 is not visible on these.
Ce mécanisme d'éjection 8 permet le mouvement selon F5, c'est-à-dire l'éjection de la prise mobile 2 par rapport au dispositif de sécurité 1, et plus exactement, de la prise de jonction 7, dudit dispositif 1.This ejection mechanism 8 allows movement along F5, that is to say the ejection of the movable socket 2 relative to the safety device 1, and more precisely, of the junction socket 7, of said device 1.
Le déclenchement du mécanisme d'éjection 8 se fait sous la traction F3 exercée sur le fil électrique de la prise mobile 2, mais également sous l'action de la traction F4 exercée sur le cordon 5, comme on le voit bien sur la figure 5.The ejection mechanism 8 is triggered under the traction F3 exerted on the electric wire of the mobile outlet 2, but also under the action of the traction F4 exerted on the cord 5, as can be seen in FIG. 5 .
Le mécanisme d'éjection 8 est essentiellement formé de trois moyens différents. Il s'agit des moyens d'armement, des moyens d'éjection proprement dits et des moyens de désarmement.The ejection mechanism 8 is essentially formed by three different means. These are the arming means, the actual ejection means and the disarming means.
L'agencement de ces différents moyens est tel que le mécanisme d'éjection est constitué essentiellement par un chariot mobile 9, monté à l'encontre de deux ressorts 10 constituant les moyens d'éjection, le chariot 9 étant mobile entre une position où chaque ressort 10 est compressé, suite à la mise en oeuvre des moyens d'armement selon la flèche F6, et plus précisément du bras d'armement 14, et une position où chaque ressort 10 est décompressée suite à la mise en oeuvre des moyens de désarmement.The arrangement of these different means is such that the ejection mechanism consists essentially of a movable carriage 9, mounted against two springs 10 constituting the ejection means, the carriage 9 being movable between a position where each spring 10 is compressed, following the implementation of the arming means according to arrow F6, and more precisely of the arming arm 14, and a position where each spring 10 is decompressed following the implementation of the disarming means .
Le chariot 9 est en fait mobile selon F7 et F8 de la figureThe carriage 9 is in fact mobile according to F7 and F8 of the figure
5. Le mouvement selon F7 est effectué par le chariot 9 lors de l'armement du mécanisme d'éjection et selon F8 lors du désarmement de celui-ci.5. The movement according to F7 is carried out by the carriage 9 when the ejection mechanism is armed and according to F8 when the latter is disarmed.
Chaque ressort 10 est monté coaxialement autour d'une colonne télescopique 11 dont les extrémités sont solidaires, d'une part, du chariot mobile 9 et, d'autre part, d'une plaque support 12.Each spring 10 is mounted coaxially around a telescopic column 11, the ends of which are integral, on the one hand, with the mobile carriage 9 and, on the other hand, with a support plate 12.
Comme on le voit bien à la figure 6, le chariot 9 comporte deux pattes 13 situées du même côté que les colonnes télescopiques 11 et les ressorts 10, et situées parallèlement à ceux-ci 10 et 11.As can be seen in Figure 6, the carriage 9 has two legs 13 situated on the same side as the telescopic columns 11 and the springs 10, and situated parallel to these 10 and 11.
L'extrémité de chaque patte 13 comporte des surfaces permettant la coopération avec les moyens d'armement et de désarmement.The end of each tab 13 has surfaces allowing cooperation with the arming and disarming means.
Sur la patte 13 située en avant du plan de la figure 6, il existe une surface de contact qui coopère lors de l'armement du mécanisme d'éjection 8 avec la came 15, portée par le bras d'armement 14.On the tab 13 located in front of the plane of FIG. 6, there is a contact surface which cooperates during the arming of the ejection mechanism 8 with the cam 15, carried by the arming arm 14.
Ce bras d'armement 14 comporte un axe de rotation 16, qui permet le mouvement selon F6 pour faire reculer le chariot 9 à 1'encontre des ressorts 10.This cocking arm 14 has an axis of rotation 16, which allows movement along F6 to make the carriage 9 move backwards against the springs 10.
Bien entendu, la came 15 peut être présente de chaque côté du bras d'armement 14. C'est ce qui est représenté sur les figures.Of course, the cam 15 can be present on each side of the cocking arm 14. This is what is shown in the figures.
Lors du recul selon F7 du chariot 9 ainsi que des pattes 13, la patte 13, située en arrière du plan de la figure 6, vient en contact avec une surface biaisée de forme équivalente à celle de la patte 13. Cette surface biaisée est portée par la détente 24. Lorsque le chariot est mû selon F7 à l'aide des moyens d'armement, la détente 24 va être éloignée latéralement selon F9, comme on le voit bien sur la figure 5.During the recoil along F7 of the carriage 9 as well as of the legs 13, the leg 13, located behind the plane of FIG. 6, comes into contact with a biased surface of shape equivalent to that of the leg 13. This biased surface is worn by the trigger 24. When the carriage is moved along F7 using the arming means, the trigger 24 will be moved laterally away along F9, as can be seen in FIG. 5.
Ce déplacement s'effectue à l'encontre d'un ressort de rappel 27 qui normalement maintient la détente 24 en position désarmée.This movement takes place against a return spring 27 which normally maintains the trigger 24 in the disarmed position.
Lorsque ladite détente 24 est dans la position armée, la gâchette 23, qui se trouve positionnée dans un axe longitudinal perpendiculaire à la détente, vient au contact avec la plaque support 12 sur laquelle sont fixées les colonnes 11. La gâchette 23 est elle-même montée à l'encontre d'un ressort de rappel 26 monté entre ladite gâchette 23 et la carcasse extérieure 20, qui est figurée sur cette figure 5.When said trigger 24 is in the armed position, the trigger 23, which is positioned in a longitudinal axis perpendicular to the trigger, comes into contact with the support plate 12 on which the columns 11 are fixed. The trigger 23 is itself mounted against a return spring 26 mounted between said trigger 23 and the outer carcass 20, which is shown in this FIG. 5.
Le ressort 26 tend à maintenir la gâchette 23 toujours en contact avec la plaque-support 12. II est donc évident que lorsque le bras d'armement 14 est actionné selon F6, le chariot 9 recule selon F7, ce qui permet l'éloignement de la détente selon F9 et ainsi, le positionnement de la gâchette 23, dans un déplacement opposé à celui de la traction F4 que peut subir le cordon 5. Dans cette position, qui correspond à la figure 6, le dispositif de sécurité 1 est armé.The spring 26 tends to keep the trigger 23 still in contact with the support plate 12. It is therefore obvious that when the arming arm 14 is actuated according to F6, the carriage 9 moves back according to F7, which allows the separation of the trigger according to F9 and thus, the positioning of the trigger 23, in a movement opposite to that of the pull F4 that the cord 5 can undergo. In this position, which corresponds to Figure 6, the safety device 1 is armed.
Comme on le voit bien sur la figure 6, cet armement est possible du fait que le chariot 9 est muni d'un crochet 21 dont l'axe d'articulation 22 situé au niveau du chariot permet le mouvement en rotation à l'encontre d'un ressort 25.As can be clearly seen in FIG. 6, this arming is possible because the carriage 9 is provided with a hook 21 whose hinge pin 22 located at the level of the carriage allows the movement in rotation against d 'a spring 25.
Lorsque le chariot 9 est amené selon F7 en position d'armement, le crochet 21 va venir s'insérer dans un espace libéré par la détente 24, ledit crochet 21 coopérant alors avec la plaque-support 12. Lorsque le dispositif de sécurité 1 subit une traction F4, la gâchette 23 va être mobile selon la même flèche F4, à l'encontre du ressort 26.When the carriage 9 is brought along F7 into the cocking position, the hook 21 will be inserted into a space freed by the trigger 24, said hook 21 then cooperating with the support plate 12. When the safety device 1 is subjected a pull F4, the trigger 23 will be movable along the same arrow F4, against the spring 26.
Ceci va créer entre la gâchette 23 et la plaque-support 12 un espace que la détente 24 va venir combler du fait de l'action de son ressort de rappel 27.This will create a space between the trigger 23 and the support plate 12 that the trigger 24 will fill due to the action of its return spring 27.
Ceci va permettre de désolidariser le crochet 21 de la plaque-support 12 et ainsi permettre de ramener le chariot 9, selon F8, de façon très rapide, assurant l'éjection de la prise électrique mobile 2 se situant sensiblement au niveau de la prise de jonction 7, non représentée sur les figures 5 à 8.This will make it possible to separate the hook 21 from the support plate 12 and thus make it possible to bring the carriage 9, according to F8, very quickly, ensuring the ejection of the mobile electrical outlet 2 located substantially at the level of the outlet. junction 7, not shown in Figures 5 to 8.
Dans le mode de réalisation des figures 5 et 6, le chariot 9 coopère avec un doigt d'éjection 18 situé, lorsque le dispositif 1 raccorde une prise mobile 2 et une prise murale fixe 3, entre la prise électrique mobile 2 et la prise de jonction 7. Le doigt d'éjection 18 se trouve au contact ou en translation longitudinale, selon F13 et F14 de la figure 7, aux abords de ladite prise de jonction 7, lorsque le mécanisme d'éjection 8 est en position armée. Par contre, le doigt d'éjection 18 est éloigné de la prise de jonction 7 lorsque la position du mécanisme d'éjection 8 est désarmée.In the embodiment of Figures 5 and 6, the carriage 9 cooperates with an ejection finger 18 located, when the device 1 connects a mobile outlet 2 and a fixed wall outlet 3, between the mobile electrical outlet 2 and the outlet junction 7. The ejection finger 18 is in contact or in longitudinal translation, according to F13 and F14 of FIG. 7, around said junction socket 7, when the ejection mechanism 8 is in the armed position. On the other hand, the ejection finger 18 is moved away from the junction socket 7 when the position of the ejection mechanism 8 is disarmed.
Dans cette configuration, le chariot 9, lorsque celui-ci est désarmé, vient frapper le doigt d'éjection 18 lors du désarmement du dispositif mécanique de sécurité 1, ce qui facilite l'éjection de la prise mobile 2. Dans ce dispositif 1, l'effet marteau amplifie encore la facilité avec laquelle l'éjection est réalisée. Pour arriver à ce résultat, il est nécessaire que, lors de l'armement, le recul du chariot mobile 9, selon F7, soit de plus grande amplitude que le recul du doigt d'éjection 18, qui s'effectue sans résistance lorsque l'on enfiche la prise électrique mobile 2, selon FI, et que l'armement a déjà été réalisé.In this configuration, the carriage 9, when the latter is disarmed, comes to strike the ejection finger 18 during disarming of the mechanical safety device 1, which facilitates the ejection of the mobile socket 2. In this device 1, the hammer effect further amplifies the ease with which the ejection is carried out. To achieve this result, it is necessary that, during arming, the recoil of the movable carriage 9, according to F7, be of greater amplitude than the recoil of the ejection finger 18, which takes place without resistance when the 'we plug the plug electric mobile 2, according to FI, and that the arming has already been carried out.
La différence d'amplitude correspond à une longueur que le chariot mobile 9 utilisera lors du désarmement, selon F8, pour prendre de la vitesse et venir frapper le doigt d'éjection 18, ce qui permettra l'éjection de la prise 2 fortement solidarisée au dispositif mécanique de sécurité 1.The difference in amplitude corresponds to a length that the mobile carriage 9 will use during disarmament, according to F8, to gain speed and strike the ejection finger 18, which will allow the ejection of the socket 2 strongly secured to the mechanical safety device 1.
Selon la figure 8, un autre mode de réalisation plus conventionnel est possible. II s'agit d'un doigt d'éjection 17 qui est situé, lorsque le dispositif 1 raccorde une prise mobile 2 et une prise murale fixeAccording to FIG. 8, another more conventional embodiment is possible. It is an ejection finger 17 which is located, when the device 1 connects a mobile outlet 2 and a fixed wall outlet
3, entre la prise électrique mobile 2 et la prise de jonction 7.3, between the mobile electrical outlet 2 and the junction outlet 7.
Ce doigt d'éjection 17 est en contact avec la prise de jonction 7 en position armée, et éloignée de la prise de jonction 7 en position désarmée.This ejection finger 17 is in contact with the junction socket 7 in the armed position, and distant from the junction socket 7 in the disarmed position.
Dans ce cas, il n'y a aucun débattement et donc pas d'effet marteau. C'est simplement la force des ressorts 10 qui va permettre ou non l'éjection de la prise mobile 2.In this case, there is no travel and therefore no hammer effect. It is simply the force of the springs 10 which will allow or not the ejection of the movable socket 2.
Quel que soit le mode de réalisation du doigt d'éjection 17 ou 18, celui-ci est formé d'un anneau de contact 19 situé dans la partie la plus extérieure, c'est-à-dire en contact avec la prise mobile 2, dont les formes sont complémentaires avec ladite priseWhatever the embodiment of the ejection finger 17 or 18, it is formed of a contact ring 19 located in the outermost part, that is to say in contact with the movable socket 2 , the forms of which are complementary with said socket
2 et facilite son éjection.2 and facilitates its ejection.
Le cordon d'alimentation 5 est solidaire de la gâchette 23 mobile en translation sous la traction F4 que subit le cordon 5, ce mouvement étant un mouvement de translation parallèle au mouvement du chariot 9. La gâchette 23 possède une section longitudinale en forme sensiblement de L. L'extrémité libre de la première branche du L, parallèle au mouvement de translation, coopère . avec une patte du chariot 9 lors de l'armement du dispositif, et la seconde branche du L est parallèle et au contact de la plaque support 12, lorsque le cordon d'alimentation 5 ne subit aucune traction.The power cord 5 is integral with the trigger 23 movable in translation under the traction F4 that the cord 5 undergoes, this movement being a translational movement parallel to the movement of the carriage 9. The trigger 23 has a longitudinal section in the form of substantially L. The free end of the first branch of L, parallel to the translational movement, cooperates. with a leg of the carriage 9 when the device is armed, and the second branch of the L is parallel and in contact with the support plate 12, when the power cord 5 is not subjected to any traction.
Cette seconde branche du L coopère avec la détente 24 mobile en translation, selon F9 et F10, dans un mouvement de translation qui est perpendiculaire au mouvement de translation de la gâchette 24, les détentes 24 et gâchette 23 coopérant ensemble pour permettre le mouvement de rotation selon Fil et F12 du crochet 21, représenté sur la figure 7. Selon les figures 9 et 10, un autre dispositif selon l'invention est représenté. Pour faciliter sa compréhension, les différentes pièces reçoivent des références identiques à celles précédemment décrites, en rapport avec leur fonction. La carcasse extérieure 20 est constituée de deux demi- coquilles, dont une seule est représentée sur les deux figures 9 et 10. La forme intérieure de la carcasse 20 permet le positionnement longitudinal central de différents éléments. Il y a tout d'abord le doigt d'éjection 18, qui coopère maintenant indirectement avec le chariot mobile 9, puisque le bras d'armement 14, et plus précisément la came 15, dudit bras 14, est insérée entre ledit doigt 18 et le chariot 9. Les parties du doigt 18 de la came 15 et du chariot 9 qui coopèrent ont une forme identique, non limitative, sous la forme d'un anneau. Le bras d'armement 14 comporte deux ergots dans le prolongement l'un de l'autre de part et d'autre du plan formé par ladite came 15. Chaque ergot est associé à un ressort de rappel 28 solidarisé à la carcasse 20, de sorte que le bras 14 est naturellement poussé en direction du doigt 18. Ce mouvement est également celui du chariot mobile 9, qui est associé à un ressort 10, dont l'extrémité libre repose contre un épaulement 29 de la carcasse 20.This second branch of the L cooperates with the trigger 24 movable in translation, according to F9 and F10, in a translational movement which is perpendicular to the translational movement of the trigger 24, the detents 24 and trigger 23 cooperating together to allow the rotational movement along Wire and F12 of hook 21, shown in Figure 7. According to Figures 9 and 10, another device according to the invention is shown. To make it easier to understand, the different parts are given identical references to those previously described, in relation to their function. The external carcass 20 consists of two half-shells, only one of which is shown in the two figures 9 and 10. The internal shape of the carcass 20 allows the central longitudinal positioning of different elements. First there is the ejection finger 18, which now cooperates indirectly with the movable carriage 9, since the cocking arm 14, and more precisely the cam 15, of said arm 14, is inserted between said finger 18 and the carriage 9. The parts of the finger 18 of the cam 15 and of the carriage 9 which cooperate have an identical shape, without limitation, in the form of a ring. The cocking arm 14 comprises two lugs in the extension of one another on either side of the plane formed by said cam 15. Each lug is associated with a return spring 28 secured to the carcass 20, so that the arm 14 is naturally pushed towards the finger 18. This movement is also that of the movable carriage 9, which is associated with a spring 10, the free end of which rests against a shoulder 29 of the carcass 20.
Dans le prolongement axial du doigt 18, du bras 14 et du chariot 9, est positionné un cordon souple d'alimentation 5, dont seule l'extrémité, coopérant avec le boîtier de raccordement 4, est représentée. En fait, cette extrémité est maintenue en position à l'intérieur d'une fente 30 du chariot mobile 9, du fait de la présence d'une douille de blocage 31 empêchant toute sortie inopinée dudit cordon 5 vis-à-vis de la carcasse 20. En fait, cette douille 31, bloquée en position par des vis 33, a une autre fonction qui est de coopérer avec le ressort 27 pour permettre le rappel en position, après une traction, de l'extrémité libre du cordon 5, et surtout de la détente 24 qui y est fixée. Cette détente 24 est un bloc comportant deux faces biaisées 32. Ces faces 32 coopèrent avec deux gâchettes 23 en forme de L, chaque extrémité libre de chaque branche du L comportant un axe perpendiculaire à l'axe longitudinal du boîtier 4. Pour chaque gâchette 23, une extrémité comporte un axe d'articulation 34 par rapport à la carcasse 20 et un axe de rappel en position 35, les deux axes 35 coopérant ensemble par l'intermédiaire d'au moins un ressort 36.In the axial extension of the finger 18, the arm 14 and the carriage 9, is positioned a flexible supply cord 5, of which only the end, cooperating with the connection box 4, is shown. In fact, this end is held in position inside a slot 30 of the movable carriage 9, due to the presence of a locking sleeve 31 preventing any unexpected exit of said cord 5 vis-à-vis the carcass 20. In fact, this socket 31, locked in position by screws 33, has another function which is to cooperate with the spring 27 to allow the free end of the cord 5 to be brought back into position, and especially the trigger 24 which is attached thereto. This trigger 24 is a block comprising two biased faces 32. These faces 32 cooperate with two L-shaped triggers 23, each free end of each branch of the L having an axis perpendicular to the longitudinal axis of the housing 4. For each trigger 23 , one end has a hinge pin 34 relative to the carcass 20 and a return pin in position 35, the two axes 35 cooperating together via at least one spring 36.
En fait, en position armée, les axes 35 sont rapprochés sous l'action du ressort 36, ils retiennent, dans la fente 30 du chariot 9, la détente 24. Pour ce faire, il y a une gorge circulaire 37 au niveau dudit chariot 9.In fact, in the armed position, the axes 35 are brought together under the action of the spring 36, they retain, in the slot 30 of the carriage 9, the trigger 24. To do this, there is a circular groove 37 at said carriage 9.
Lorsqu'une traction selon F4 (voir figures 3 et 5) est exercée sur le cordon 5, la détente 24 est déplacée vers l'extérieur de la fente 30. Elle 24 va permettre l'écartement des deux gâchettes 23, à l'encontre du ressort 36, par rotation autour de leurs axes d'articulation 34. Ceci va permettre le désengagement des gâchettes 23 de la gorge circulaire 37. Le chariot 9 va donc être projété vers l'avant et va venir frapper le doigt d'éjection 18, dont la position est reculée lorsqu'une prise électrique mobile 2 est enfichée sur une prise de jonction 7, non représentée sur la figure 9, mais qui est présente au coeur dudit doigt 18 et solidarisée à la carcasse extérieure 20. When traction according to F4 (see FIGS. 3 and 5) is exerted on the cord 5, the trigger 24 is moved towards the outside of the slot 30. It 24 will allow the separation of the two triggers 23, against of the spring 36, by rotation about their axes of articulation 34. This will allow the disengagement of the triggers 23 from the circular groove 37. The carriage 9 will therefore be projected forward and will strike the ejection finger 18 , whose position is moved back when a mobile electrical outlet 2 is plugged into a junction outlet 7, not shown in FIG. 9, but which is present at the heart of said finger 18 and secured to the outer carcass 20.
