Cette première partie dite fixe 6 comporte une première portion 8 s'étendant sensiblement parallèlement au plan de la face avant de l'appareil, une seconde portion 9 s'étendant sensiblement perpendiculairement à cette première portion 8, et une troisième portion 10 s'étendant sensiblement perpendiculairement à la face avant de l'appareil et située entre la manette M de l'appareil et cette seconde portion 9.This first so-called fixed portion 6 comprises a first portion 8 extending substantially parallel to the plane of the front face of the apparatus, a second portion 9 extending substantially perpendicularly to this first portion 8, and a third portion 10 extending substantially perpendicular to the front face of the apparatus and located between the handle M of the apparatus and this second portion 9.

En se reportant plus particulièrement à la figure 9, on voit que cette seconde partie dite mobile 7 de l'organe de verrouillage 5, est formée par une pièce en forme de U comportant une base 11 et deux ailes 12,13 et une partie massive 14 située entre les deux ailes 12,13.With particular reference to the figure 9 it can be seen that this second so-called mobile part 7 of the locking member 5 is formed by a U-shaped part comprising a base 11 and two wings 12, 13 and a solid part 14 situated between the two wings 12, 13 .

Cette partie massive 14 s'étend seulement sur une partie de la largeur des ailes 12,13 de manière à former de part et d'autre de cette partie massive 14, sur la surface interne de l'une 12 des ailes 12,13, des zones d'appui et de guidage 12a,12b destinées à coopérer avec des zones complémentaires d'appui et de guidage 10c,10 e prévues sur la troisième portion 10 de la partie fixe précitée 6, cette troisième portion 10 étant constituée par deux demi-portions 10a,10b. L'autre 13 des deux ailes 12,13 comporte deux bords longitudinaux libres formant des surfaces de guidage 13a,13b destinées à coopérer respectivement avec des zones de guidage complémentaires 10d, 10f appartenant respectivement aux deux demi-portions précitées 10a,10b. La partie massive précitée 14 de la partie mobile 7 comporte deux surfaces (dont seule l'une 14a est représentée sur la figure 9) formant des surfaces de guidage aptes à coopérer à coulissement avec respectivement deux surfaces en regard 10g,10h formées respectivement aux deux parties d'extrémités des deux demi-portions 10a,10b.This solid part 14 extends only over part of the width of the flanges 12, 13 so as to form on either side of this solid part 14, on the inner surface of one of the flanges 12, 13, bearing and guiding zones 12a, 12b intended to cooperate with complementary bearing and guiding zones 10c, 10e provided on the third portion 10 of the aforementioned fixed part 6, this third portion being constituted by two half -portions 10a, 10b. The other 13 of the two wings 12,13 has two free longitudinal edges forming guide surfaces 13a, 13b for cooperating respectively with complementary guide zones 10d, 10f respectively belonging to the two half-portions above 10a, 10b. The aforementioned massive part 14 of the moving part 7 has two surfaces (of which only one 14a is shown on the figure 9 ) forming guide surfaces adapted to cooperate slidingly with respectively two facing surfaces 10g, 10h formed respectively at the two end portions of the two half-portions 10a, 10b.

Cette partie massive 14 comporte à son extrémité située à l'extrémité opposée à celle comportant la base du U précité, dit premier, un évidement 14c présentant dans un plan s'étendant perpendiculairement aux ailes 12,13 de la partie mobile 7, une section en forme de U, dit second U.This solid portion 14 has at its end located at the opposite end to that comprising the base of said U, said first, a recess 14c having in a plane extending perpendicularly to the flanges 12, 13 of the movable portion 7, a section U-shaped, says second U.

En se reportant plus particulièrement aux figures 6 et 8, on voit que la première portion précitée 8 de la partie fixe 6 comporte également deux portions de surface 8a,8b formant chacune une surface de guidage pour l'une des ailes précitées 12,13, et comporte également des éléments 19 aptes à faciliter le coulissement de la partie mobile 7 par rapport à la partie fixe 6.With particular reference to figures 6 and 8 it can be seen that the aforementioned first portion 8 of the fixed portion 6 also comprises two surface portions 8a, 8b each forming a guiding surface for one of the aforementioned wings 12, 13, and also comprises elements 19 able to facilitate the sliding of the mobile part 7 with respect to the fixed part 6.

La deuxième portion 9 de la partie fixe 6 comporte deux portions 9a,9b s'étendant dans un plan sensiblement perpendiculaires au plan de la première portion 8 et comporte d'une part, des moyens de guidage 9c et 9d des parties d'extrémité des ailes précitées.The second portion 9 of the fixed portion 6 comprises two portions 9a, 9b extending in a plane substantially perpendicular to the plane of the first portion 8 and comprises on the one hand, guide means 9c and 9d of the end portions of the aforementioned wings.

Le déplacement de la partie mobile 7 du côté de la manette M est limité par l'intermédiaire d'un crochet 15 appartenant à la première portion 8 de la partie fixe précitée 6, s'étendant sensiblement parallèlement à cette première portion 8 et apte à coopérer avec un évidement 21 de forme correspondante prévu dans la face extérieure de l'une 13 des ailes du U précité. Le déplacement de la partie mobile 7 du côté du capot est limité par la base 11 du U de la partie mobile 7 venant en butée sur les portions 10a, 10b.The displacement of the mobile part 7 on the side of the lever M is limited by means of a hook 15 belonging to the first portion 8 of the aforementioned fixed part 6, extending substantially parallel to this first portion 8 and adapted to cooperate with a recess 21 of corresponding shape provided in the outer face of a 13 of the wings of the aforementioned U. The displacement of the movable portion 7 of the hood side is limited by the base 11 of the U of the movable portion 7 abuts on the portions 10a, 10b.

L'autre évidement 14c prévu dans la partie massive 14 est destiné à permettre le passage de l'anse 16 d'un cadenas (non représenté), ladite anse 16 étant destinée à être interposée entre la paroi de fond 14d de l'évidement 14c et la seconde portion 9 de la partie fixe 6, afin de maintenir la partie mobile 7 de l'organe de verrouillage 5 dans la seconde position précitée, c'est-à-dire dans une position dans laquelle cette partie mobile 7 empêche la manoeuvre de l'organe de manoeuvre M et permet le retrait du capot 2.The other recess 14c provided in the solid portion 14 is intended to allow the passage of the handle 16 of a padlock (not shown), said handle 16 being intended to be interposed between the bottom wall 14d of the recess 14c and the second portion 9 of the fixed portion 6, in order to maintain the movable portion 7 of the locking member 5 in the aforementioned second position, that is to say in a position in which the movable portion 7 prevents the maneuver of the operating member M and allows the removal of the cover 2.

En se reportant plus particulièrement à la figure 2, on notera également la présence, sur le capot de protection 2 du dispositif de réglage R, d'une fenêtre 17 permettant la visualisation du calibre de l'appareil.With particular reference to the figure 2 , it will also be noted the presence, on the protective cover 2 of the adjustment device R, a window 17 for viewing the gauge of the device.

Le fonctionnement du dispositif de verrouillage 4 selon la réalisation particulière décrite précédemment va être décrit dans ce qui suit en référence aux figures.The operation of the locking device 4 according to the particular embodiment described above will be described in the following with reference to the figures.

Sur la figure 1, le dispositif de verrouillage 4 est en position déverrouillée, la partie mobile 7 de l'organe de verrouillage 5 étant déplacé dans une direction opposée à l'organe de manoeuvre M de manière à empêcher le retrait du capot de protection 2 donnant accès au dispositif de réglage R. Dans cette position, l'utilisateur est libre de manoeuvrer l'organe de manoeuvre M, appelé communément manette. Un plombage 18 du capot 2 au moyen du dispositif de plombage a pu être réalisé de manière à signaler qu'aucune ouverture du capot n'a été réalisée préalablement.On the figure 1 , the locking device 4 is in the unlocked position, the moving part 7 of the locking member 5 being displaced in a direction opposite to the actuating member M so as to prevent the removal of the protective cover 2 giving access to the device R. In this position, the user is free to operate the actuator M, commonly called joystick. A sealing 18 of the cover 2 by means of the sealing device could be achieved so as to indicate that no opening of the cover was previously performed.

Dans une position non représentée dans laquelle l'organe de manoeuvre M est en position ON, cet organe de manoeuvre empêche le déplacement de l'organe de verrouillage 5 vers cet organe de manoeuvre M et donc maintient cet organe de verrouillage 5 dans une position dans laquelle il empêche le retrait du capot 2. Sur la figure 2, l'appareil a été amené en position OFF au moyen de l'organe de manoeuvre M, le dispositif de plombage 18 a été désactivé et la partie mobile 7 de l'organe de verrouillage 5 a été déplacée en translation par rapport à la partie fixe 6 en direction de la manette M de l'appareil, de manière à bloquer la manette dans cette position OFF.In a position not shown in which the actuating member M is in the ON position, this actuating member prevents the displacement of the locking member 5 towards this operating member M and thus maintains this locking member 5 in a position in which prevents the removal of the hood 2. On the figure 2 , the apparatus was brought to the OFF position by means of the actuator M, the sealing device 18 was deactivated and the movable portion 7 of the locking member 5 was moved in translation relative to the part fixed 6 towards the handle M of the device, so as to lock the handle in this OFF position.

Ce déplacement de la partie mobile de l'organe de verrouillage 5 permet à un utilisateur de déplacer le capot de protection 2 du dispositif de réglage R en translation perpendiculairement aux faces avant et arrière de l'appareil, et vers l'avant de l'appareil, de manière à autoriser l'accès au dispositif de réglage R, cette position étant illustrée sur la figure 3, ou la figue 4 illustrant l'organe de verrouillage seul 5.This displacement of the movable portion of the locking member 5 allows a user to move the protective cover 2 of the adjustment device R in translation perpendicularly to the front and rear faces of the device, and towards the front of the apparatus, so as to allow access to the adjusting device R, this position being illustrated on the figure 3 , or fig 4 illustrating the locking member alone 5.

Le dispositif de verrouillage 4 peut être cadenassé dans cette position dans laquelle l'organe de manoeuvre M de l'appareil est bloqué en position OFF au moyen d'un cadenas dont l'anse 16 peut être introduite dans l'évidement 14c prévu dans la partie massive 14, entre le fond 14d de forme incurvée de la partie massive 14 de la partie mobile 7 de l'organe de verrouillage 5 et la seconde portion 9 de la partie fixe 6 de l'organe de verrouillage 5, cette position étant illustrée sur la figure 10.The locking device 4 can be padlocked in this position in which the actuator M of the apparatus is locked in the OFF position by means of a padlock whose handle 16 can be inserted into the recess 14c. provided in the solid portion 14, between the bottom 14d of curved shape of the solid portion 14 of the movable portion 7 of the locking member 5 and the second portion 9 of the fixed portion 6 of the locking member 5, this position being illustrated on the figure 10 .

On notera que la mise en place de ce cadenas pourra être réalisée aussi bien avant, qu'après le retrait du capot de protection 2.Note that the establishment of this padlock can be performed both before, after the removal of the protective cover 2.

Une fois le réglage de l'appareil réalisé, l'utilisateur désactive le cadenas, puis déplace la partie mobile 7 de l'organe de verrouillage 5 en direction du capot 2, ce qui permet de libérer l'organe de manoeuvre M de l'appareil, lequel peut donc ensuite être actionné vers la position ON de l'appareil. Dans cette position, un nouveau plombage du capot 2 peut être réalisé de manière à pouvoir signaler une éventuelle manipulation ultérieure non autorisée du capot.Once the device has been adjusted, the user deactivates the padlock and then moves the movable part 7 of the locking member 5 in the direction of the cover 2, thereby making it possible to release the operating member M from the lock device, which can then be switched to the ON position of the device. In this position, a new seal of the cover 2 can be made so as to indicate any subsequent unauthorized manipulation of the cover.

On notera que lors de son déplacement en translation, la partie mobile 7 de l'organe de verrouillage 5 coulisse par rapport à la partie fixe 6, par l'intermédiaire des zones de guidage 12a,12b,13a,13b prévues sur la partie mobile 7 coopérant avec les zones de guidage correspondantes 10c,10d,10e,10f prévues sur les deux portions de cloison 10a,10b formant la troisième portion 10 de la partie fixe 6, par l'intermédiaire également des zones de guidage 8a,8b prévues sur la première portion 8 de la partie fixe 6 et par l'intermédiaire des moyens de guidage 9c et 9d prévus sur la seconde portion 9 de la partie fixe 6 coopérant avec des zones de guidage correspondantes prévues sur les parties d'extrémité des ailes du U formé par la partie mobile 7 de l'organe de verrouillage 5.It will be noted that during its displacement in translation, the mobile part 7 of the locking member 5 slides relative to the fixed part 6, through the guide zones 12a, 12b, 13a, 13b provided on the moving part. 7 cooperating with the corresponding guide areas 10c, 10d, 10e, 10f provided on the two partition portions 10a, 10b forming the third portion 10 of the fixed portion 6, also via the guide zones 8a, 8b provided on the first portion 8 of the fixed portion 6 and through the guiding means 9c and 9d provided on the second portion 9 of the fixed portion 6 cooperating with corresponding guide zones provided on the end portions of the wings of the U formed by the movable part 7 of the locking member 5.

Le déplacement de la partie mobile 7 de l'organe de verrouillage 5 vers la capot 2 est arrêté par la troisième portion 10a,10b de la partie fixe 6 formant butée coopérant avec la base 11 de la partie mobile 7, tandis que le déplacement de la partie mobile 7 dans la direction opposée est limitée par le crochet 15 appartenant à la première portion 8 de la partie fixe 6 coopérant avec le bord 22 de l'évidement correspondant 21 prévu sur la face extérieure de l'aile 13 du U précité.The displacement of the movable portion 7 of the locking member 5 towards the cover 2 is stopped by the third portion 10a, 10b of the fixed portion 6 forming an abutment cooperating with the base 11 of the movable part 7, while the displacement of the moving part 7 in the opposite direction is limited by the hook 15 belonging to the first portion 8 of the fixed part 6 cooperating with the edge 22 of the corresponding recess 21 provided on the outer face of the flange 13 of the aforementioned U.

L'invention permet de supprimer le système de trappe de réglage utilisé dans les appareils de l'art antérieur, ladite trappe étant facilement perdable compte-tenu notamment de sa petite taille. De plus, un seul capot est utilisé pour protéger les bornes d'arrivée et le dispositif de réglage, ce qui réduit le nombre de pièces utilisées.The invention makes it possible to eliminate the adjustment flap system used in the apparatuses of the prior art, said flap being easily lost, particularly in view of its small size. In addition, only one hood is used to protect Incoming terminals and adjusting device, which reduces the number of parts used.

Le dispositif de verrouillage selon l'invention permet de s'assurer qu'aucune énergie n'est consommée sans déposer d'appareil.The locking device according to the invention makes it possible to ensure that no energy is consumed without depositing apparatus.

On a donc réalisé grâce à l'invention, un dispositif de verrouillage de conception simple, en ce qu'il ne nécessite pas de pièce ajoutée, utilise un nombre de pièces réduit, lesdites pièces étant imperdables, et obligeant l'utilisateur à manoeuvrer l'appareil en position OFF avant d'effectuer le retrait du capot de protection du dispositif de réglage, cette manipulation garantissant la sécurité de l'utilisateur, les pièces dénudées étant mises hors tension.It has therefore been realized thanks to the invention, a locking device of simple design, in that it does not require any added part, uses a reduced number of parts, said parts being captive, and forcing the user to manipulate the device. in the OFF position before removal of the protective cover from the adjustment device, this manipulation guaranteeing the safety of the user, the stripped parts being de-energized.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et illustré qui n'a été donné qu'à titre d'exemple.Of course, the invention is not limited to the embodiment described and illustrated which has been given by way of example.

C'est ainsi que cette invention s'applique à tous les appareils dont une partie doit être retirée pour régler l'appareil.Thus this invention applies to all devices from which a part must be removed to adjust the device.

Au contraire, l'invention comprend tous les équivalents techniques des moyens décrits ainsi que leurs combinaison si celle-ci sont réalisées suivant son esprit.On the contrary, the invention comprises all the technical equivalents of the means described and their combination if the latter are carried out according to its spirit.
