Description

L'invention concerne un dispositif de verrouillage destiné à brider temporairement des pièces devant être immobilisées avec fermeté par exemple des portes de sas ou d'autoclaves, des panneaux d'étanchéité, des écoutilles, ledit dispositif pouvant être utilisé soit comme verrou lorsqu'il est fixé sur le dormant d'une ouverture, soit comme dispositif de bridage de pièces à usiner lorsqu'il est fixé à la table d'une machine-outil.The invention relates to a locking device intended for temporarily clamping parts which must be firmly fixed, for example airlock doors or autoclaves, sealing panels, hatches, said device being able to be used either as a lock when is fixed to the frame of an opening, or as a device for clamping workpieces when it is fixed to the table of a machine tool.

On connaît déjà des verrous de ce genre destinés à exercer une force d'appui élevée sur un élément à brider avec fermeté, ceux-ci étant constitués généralement d'une semelle d'appui immobilisée sur un support par des moyens de fixation et coopérant avec un bras ou une mâchoire de bridage animé d'un mouvement de balancier pour pouvoir sous l'action d'un organe de commande, le plus souvent rotatif, pivoter pour que l'une de ses extrémités dite "de bridage"vienne en appui sur la pièce ou élément à immobiliser. La difficulté naît le plus souvent de ce que le bras de bridage, s'il est mobile angulairement, n'est pas ou peu déplaçable dans son plan longitudinal de sorte que son utilisation est limitée aux seules pièces accessibles, c'est-à-dire à celles immédiatement en regard de sa zone d'appui (extrémité de bridage).Locks of this kind are already known which are intended to exert a high bearing force on an element to be clamped firmly, these generally consisting of a bearing sole immobilized on a support by fixing means and cooperating with a clamping arm or jaw animated by a pendulum movement so as to be able, under the action of a control member, most often rotary, to pivot so that one of its ends called "clamping" comes to bear on the part or element to be immobilized. The difficulty most often arises from the fact that the clamping arm, if it is angularly movable, is not or only slightly movable in its longitudinal plane so that its use is limited to only accessible parts, that is to say tell those immediately opposite its support zone (clamping end).

L'invention concerne un verrou de bridage de ce type présentant l'originalité d'être animé d'un mouvement de translation longitudinale et d'un mouvement angulaire à partir d'un seul et même organe de commande de manière à ce que ledit bras de bridage, jouant le rôle de coulisseau, puisse être amené en regard de la pièce à brider (par déplacement longitudinal) puis pivoter (déplacement angulaire) en direction de la pièce à immobiliser.The invention relates to a clamping latch of this type having the originality of being animated by a longitudinal translational movement and an angular movement from a single control member so that said arm clamping, playing the role of slide, can be brought opposite the workpiece to be clamped (by longitudinal movement) and then pivot (angular movement) towards the workpiece to be immobilized.

Ce but est atteint par le fait que le dispositif comporte un embrayage en liaison, par des moyens d'entraînement, avec le coulisseau, ledit embrayage étant porté par l'organe de commande, lui-même mobile en rotation par rapport à la semelle d'appui, des moyens de butées immobilisant longitudinalement le coulisseau,ce qui provoque le désaccouplement automatique de l'embrayage et le pivotement dudit coulisseau, lorsque l'on poursuit la rotation de l'organe de commande.This object is achieved by the fact that the device comprises a clutch in connection, by drive means, with the slide, said clutch being carried by the member. control, itself movable in rotation relative to the support sole, stop means longitudinally immobilizing the slide, which causes the automatic uncoupling of the clutch and the pivoting of said slide, when the rotation is continued of the control unit.

Selon une caractéristique de l'invention, le coulisseau comporte une lumière traversée par l'organe de commande et se déplace à l'intérieur d'un pontet, solidaire de la semelle d'appui, et pourvu d'un pivot d'articulation autour duquel bascule ledit organe de commande au cours de son mouvement angulaire.According to a characteristic of the invention, the slide comprises a light passed through by the control member and moves inside a trigger guard, integral with the support sole, and provided with a pivot for articulation around which switches said control member during its angular movement.

Selon des modes de réalisation préférentiels,les moyens de butée sont constitués notamment par les extrémités de la lumière du coulisseau venant en appui sur l'organe de commande, ou encore par la face frontale avant du coulisseau venant en appui sur un élément intermédiaire, tel que l'épaulement d'une pièce à brider.According to preferred embodiments, the abutment means are constituted in particular by the ends of the lumen of the slider bearing on the control member, or also by the front end face of the slider bearing on an intermediate element, such as the shoulder of a workpiece.

Selon un exemple de réalisation non limitatif, les moyens d'entraînement du coulisseau sont constitués d'un doigt, solidaire de l'embrayage, pris dans la fourchette constituée par deux pions, dont l'écartement correspond à la course angulaire de l'embrayage, le doigt venant alternativement en butée sur l'un ou l'autre pion, selon la position "sortie ou rétractée" du coulisseau.According to a nonlimiting exemplary embodiment, the drive means of the slide consist of a finger, integral with the clutch, taken from the fork formed by two pins, the spacing of which corresponds to the angular travel of the clutch , the finger alternately coming into abutment on one or the other pin, depending on the "out or retracted" position of the slide.

D'autres caractéristiques et avantages de l'invention ressortiront de la description ci-après et des dessins annexés dans lesquels :

  • - la Fig. 6 est une vue en coupe selon la ligne A-A de la figure 2,
  • - la Fig. 7 est une vue en plan d'une cale élévatrice utilisée pour modifier la hauteur de bridage du dispositif,
Other characteristics and advantages of the invention will emerge from the description below and the attached drawings in which:
  • - Figs. from 1 to 3 are views in longitudinal section successively illustrating three operating phases of the device according to the invention,

Le dispositif de bridage selon l'invention qui, comme indiqué précédemment, s'apparente à un verrou, est constitué essentiellement de trois pièces distinctes :

  • - la semelle d'appui 1,
  • - le coulisseau de bridage 2, et
  • - l'organe de commande 3 assurant le déplacement longitudinal et angulaire dudit.coulisseau.
The clamping device according to the invention which, as indicated above, is similar to a lock, consists essentially of three separate parts:
  • - the support sole 1,
  • - the clamping slide 2, and
  • - The control member 3 ensuring the longitudinal and angular movement of Said.coulisseau.

La semelle d'appui 1 se présente sous la forme d'une platine pourvue d'un perçage à épaulement 4 dans lequel est inséré une douille taraudée 5 recevant la portée filetée 31 de l'organe de commande 3. Cette semelle d'appui comporte également un orifice 6 servant au passage d'un organe de fixation 7 telle qu'une vis à tête à six pans creux destinée à fixer la semelle sur un support qui peut être une porte de sas, d'autoclave ou encore un panneau de fermeture étanche, voire également une table de machine-outil si le dispositif n'est pas utilisé comme verrou mais comme simple organe de bridage de pièces à usiner.The support sole 1 is in the form of a plate provided with a shoulder bore 4 into which is inserted a threaded socket 5 receiving the threaded bearing 3 1 of the control member 3. This support sole also comprises an orifice 6 serving for the passage of a fixing member 7 such as a hexagon socket head screw intended to fix the soleplate on a support which can be an airlock door, an autoclave or even a panel watertight closure, or even a machine tool table if the device is not used as a lock but as a simple member for clamping workpieces.

Le coulisseau 2 se présente sous la forme d'un bras allongé et comporte une lumière 8 que traverse l'organe de commande 3, ledit coulisseau comportant à son extrémité 21 dite "d'appui" un patin 9 monté articulé pour pouvoir prepdre une position rigoureusement horizontale même lorsque ledit coulisseau est lui-même en position inclinée comme illustré en figure 3. Le montage du patin 9 s'effectue (figure 6) par un système usuel d'encliquetage à billes.Le patin 9 comporte en effet, une mortaise 10 dans laquelle pénètre une nervure ou tenon 11 attenante au coulisseau 2, les deux ailes 91,92 de ce patin 9 étant de type hémisphérique, les épaulements 111et 112 du coulisseau étant de forme complémentaire pour constituer des sièges de pivotement dudit patin 9. La neryure 11 du coulisseau 2 est pourvue d'un alèsage transversal 12 recevant deux billes 13 sollicitéestoutes deux vers l'extérieur, dans des directions opposées, par un ressort 14, leur sortie étant rendue impossible par une bavure ou un abattement du chanfrein des deux extrémités de l'orifice 12. Ainsi le patin se monte de façon usuelle par simple encliquetage, puisqu'il comporte également deux orifices 15 traversant de part en part ses joues 91 et 92. Ce type d'accouplement permet d'obtenir l'amovibilité du patin ainsi que son articulation sur rotule.The slider 2 is in the form of an elongated arm and has a slot 8 which passes through the control member 3, said slider comprising at its end 2 1 called "bearing" a shoe 9 mounted articulated to be able to prepdre a strictly horizontal position even when said slide is itself in an inclined position as illustrated in FIG. 3. The mounting of the pad 9 is carried out (FIG. 6) by a usual system of ball snap-fastening. The pad 9 indeed comprises, a mortise 10 into which penetrates a rib or tenon 11 adjoining the slide 2, the two wings 9 1 , 9 2 of this shoe 9 being of hemispherical type, the shoulders 11 1 and 11 2 of the slide being of complementary shape for constitute pivoting seats of said shoe 9. The groove 11 of the slide 2 is provided with a transverse bore 12 receiving two balls 13 which are biased all two outwards, in opposite directions, by a spring 14, their outlet being made impossible by a burr or a reduction in the chamfer of the two ends of the orifice 12. Thus the shoe is mounted in the usual way by simple snap-fastening, since it also comprises two orifices 15 passing right through its cheeks 9 1 and 9 2 . This type of coupling makes it possible to obtain the removability of the skate as well as its articulation on ball joint.

L'organe de commande est constitué ici d'un axe 3, pourvu d'une part de la portée filetée 31 se vissant dans la douille taraudée 5, d'autre part de moyens de commande de basculement du coulisseau 2 et enfin d'une portée recevant l'embrayage 16, elle-même prolongée par une tête de manoeuvre 17, par exemple en forme d'écrou. Les moyens provoquant le mouvement angulaire du coulisseau 2 sont formés d'une coupelle hémisphérique 18 prolongant la portion filetée 31 de l'axe de commande, celle-ci étant en appui sur une bague 19 pincée entre cette coupelle et la face inférieure 22 du coulisseau 2. Cette bague 19 comporte un siège 191 ayant une forme complémentaire de la coupelle hémisphérique 18. L'axe de commande 3 est solidaire axialement du coulisseau 2 d'une part par une bague 22 située au regard de la face supérieure 23 du coulisseau et d'autre part par des circlips 20 et 21 entre lesquels est fixé l'embrayage 16. Cet embrayage est constitué ici d'une bague fendue 16montée à friction sur la portée lisse 32 de l'axe 3, le jeu éventuel de cette bague 16 pouvant être rattrapé à l'aide d'une vis de réglage 16 pour serrer radialement la bague 16 sur ledit axe 3 .The control member here consists of an axis 3, provided on the one hand with the threaded surface 3 1 screwing into the threaded sleeve 5, on the other hand with means for controlling the tilting of the slide 2 and finally with a bearing surface receiving the clutch 16, itself extended by an operating head 17, for example in the form of a nut. The means causing the angular movement of the slide 2 are formed by a hemispherical cup 18 extending the threaded portion 3 1 of the control axis, this being in abutment on a ring 19 pinched between this cup and the lower face 2 2 of the slide 2. This ring 19 comprises a seat 19 1 having a shape complementary to the hemispherical cup 18. The control axis 3 is axially integral with the slide 2 on the one hand by a ring 22 located opposite the upper face 2 3 of the slide and on the other hand by circlips 20 and 21 between which is fixed the clutch 16. This clutch consists here of a split ring 16 friction mounted on the smooth surface 3 2 of the axis 3, the clearance possible of this ring 16 can be caught up using an adjusting screw 16 to radially tighten the ring 16 on said axis 3.

La semelle d'appui 1 comporte enfin une réhausse 23 en forme de pontet (figure 1) que traverse le coulisseau 2, le bord supérieur 241 de l'ouverture 24 (de forme sensiblement carrée) traversant de part en part le pontet 23 comportant un pivot 25 formé d'un axe s'étendant sur toute la largeur de l'ouverture du pontet et sur les génératrices duquel s'articule le coulisseau 2 à la manière d'un fléau de balance,The support sole 1 finally comprises an extension 23 in the form of a trigger guard (FIG. 1) through which the slide 2 passes, the upper edge 24 1 of the opening 24 (of substantially square shape) passing right through the trigger guard 23 comprising a pivot 25 formed by an axis extending over the entire width of the opening of the trigger guard and on the generatrices of which the slide 2 is articulated in the manner of a balance beam,

Le fonctionnement de ce verrou s'effectue de la façon suivante :

  • dans la position initiale des pièces, c'est-à-dire lorsque le verrou est au repos, le coulisseau 2 occupe (figure 1), la position P illustré en trait mixte, c'est-à-dire qu'il est rétracté et que son extrémité d'appui 21 est pratiquement au droit de la face avant 11 de la semelle d'appui 1. A ce stade l'axe de commande 3 est en position Basse, c'est-à-dire que sa portée filetée 31 est au fond de la douille taraudée 5. Cette position correspond en fait à la position la plus basse du coulisseau. Enfin, le coulisseau est légèrement incliné, son extrémité d'appui 21 étant légèrement plus haute que son extrémité arrière 24. On observe également que dans cette position du coulisseau, celui-ci est en appui contre le pivot d'articulation 25 porté par le pontet 23.
The operation of this lock is as follows:
  • in the initial position of the parts, that is to say when the bolt is at rest, the slider 2 occupies (FIG. 1), the position P illustrated in phantom, that is to say that it is retracted and that its support end 2 1 is practically in line with the front face 1 1 of the support sole 1. At this stage the control pin 3 is in the lower position, that is to say that its threaded bearing 3 1 is at the bottom of the threaded sleeve 5. This position corresponds in fact to the lowest position of the slide. Finally, the slide is slightly inclined, its support end 2 1 being slightly higher than its rear end 2 4 . It is also observed that in this position of the slide, the latter is in abutment against the articulation pivot 25 carried by the trigger guard 23.

Lorsque l'on procède à la rotation de l'axe 3 par exemple par le jeu d'une clé en prise sur la tête polygonale 17 on provoque par cette rotation le déplacement du coulisseau vers l'avant en raison de l'embrayage 16 qui est accouplé audit coulisseau par un doigt d'entraînement 26 prisonnier d'une fourchette formée de deux pions 27 en saillie sur la face supérieure du coulisseau, la distance comprise entre ces deux pions permettant la course angulaire de la bague d'embrayage 16 et par conséquent de l'axe de commande 3,dont elle est solidaire en rotation. La course longitudinale du coulisseau est déterminée par conséquent par l'un des deux pions 27, mais également par la butée de l'extrémité arrière 81 de la lumière oblongue 8 du coulisseau comme visible en figure 2. A ce stade en effet, le coulisseau est immobilisé axialement et sa course est par conséquent interrompue. Si l'on poursuit alors la rotation de l'axe de commande 3 le couple d'entratnement devient supérieur au couple résultant de la friction de la bague 16 sur cet axe et on assiste alors à une désolidarisation des deux composants puisque,d'une part le coulisseau est immobilisé axialement et qued'autre part, la bague de friction 16, solidaire du coulisseau par le doigt d'entraînement 26 et les pions 27,est quant à elle,bloquée en rotation. Lorsque la bague de friction 16 est désolidarisée de l'axe de commande 3 et que l'on persévère dans la rotation de cet axe, celui-ci se déplace verticalement par le vissage dans la douille 5, il se produit alors, par contre-réaction un basculement du coulisseau autour du pivot d'articulation 25. Cette contre-réaction est due au fait que le sens de rotation de l'axe de commande 3 est inverse du pas du filetage de la douille taraudée 5 de la semelle d'appui 1. Ainsi, si le pas de cette douille est à gauche et que la rotation de l'axe de commande se fait à droite, ledit axe aura tendance à remonter comme cela apparaît en figure 2 soulevant ainsi le coulisseau 2 contre lequel il est en appui par la coupelle hémisphérique 18 et la bague flottante 19.When one proceeds to the rotation of the axis 3 for example by the play of a key engaged on the polygonal head 17 one causes by this rotation the displacement of the slide forward because of the clutch 16 which is coupled to said slide by a drive finger 26 trapped in a fork formed by two pins 27 projecting from the upper face of the slide, the distance between these two pins allowing the angular travel of the clutch ring 16 and by Consequently of the control axis 3, of which it is integral in rotation. The longitudinal stroke of the slide is therefore determined by one of the two pins 27, but also by the stop of the rear end 8 1 of the oblong slot 8 of the slide as visible in FIG. 2. At this stage, in fact, the slide is immobilized axially and its stroke is consequently interrupted. If the rotation of the control axis 3 is then continued, the drive torque becomes greater than the torque resulting from the friction of the ring 16 on this axis and there is then a separation of the two components since, on the one hand the slider is immobilized axially and on the other hand, the friction ring 16, integral with the slider by the drive finger 26 and the pins 27, is in turn, locked in rotation. When the friction ring 16 is detached from the control axis 3 and that one perseveres in the rotation of this axis, the latter moves vertically by screwing into the sleeve 5, it then occurs, by cons reaction a tilting of the slide around the articulation pivot 25. This feedback is due to the fact that the direction of rotation of the control axis 3 is opposite to the pitch of the thread of the threaded bush 5 of the support sole 1. Thus, if the pitch of this socket is on the left and the rotation of the control axis is on the right, said axis will tend to go back up as it appears in figure 2 thus raising the slide 2 against which it is in support by the hemispherical cup 18 and the floating ring 19.

En figure 2 le coulisseau 2 est sensiblement horizontal et a, par conséquent, commencé son pivotement si on le compare à sa position en figure 1. Il ressort des explications précédentes que le mouvement angulaire du coulisseau ne débute qu'après la fin de son déplacement axial. Ces deux mouvements sont successifs et la transition est assurée par le débrayage de la bague fendue 16 de sorte que les mouvements de translation et de balancier ont lieu immédiatement l'un après l'autre,sans temps d'arrêt.In FIG. 2, the slider 2 is substantially horizontal and has therefore started its pivoting when compared to its position in FIG. 1. It appears from the preceding explanations that the angular movement of the slider does not start until after the end of its displacement. axial. These two movements are successive and the transition is ensured by the disengagement of the split ring 16 so that the translational and pendulum movements take place immediately one after the other, without stopping time.

On observe en figure 3 que l'axe de commande 3 est dans la position haute maximum et que le coulisseau 2 a terminé sa course angulaire par rapport à l'axe de commande 3. Dans cette position la zone d'appui 21 du coulisseau et son patin 9 bride avec fermeté (en raison du bras de levier que constitue le coulisseau 2) l'élément 29 devant être verrouillé qui peut être, comme indiqué précédemment,une pièce à usiner ou encore le dormant ou l'huisserie d'une porte, d'une fenêtre ou d'un récipient à haute étanchéité tel qu'un autoclave ou une cuve quelconque.It can be seen in FIG. 3 that the control axis 3 is in the maximum high position and that the slide 2 has finished its angular travel relative to the control axis 3. In this position the support zone 2 1 of the slide and its shoe 9 flange firmly (due to the lever arm that constitutes the slide 2) the element 29 to be locked which can be, as indicated above, a workpiece or the frame or the frame of a door, window or high-tight container such as an autoclave or any vessel.

Le mouvement angulaire du coulisseau 2 peut intervenir avant que sa course axiale soit terminée, En effet, on a observé que si la pièce 29 à brider (figure 2) a- une forme en escalier et que la phase frontale 21 du coulisseau vient en butée sur cette pièce(avant que sa course longitudinale soit complète), que l'action de bridage par pivotement du coulisseau se réalisait, puisque dès que le coulisseau rencontre une résistance,l'émbrayage 16 cède de sorte que l'axe de commande 3 tourne seul, entraînant par réaction le basculement dudit coulisseau.The angular movement of the slider 2 can intervene before its axial travel is finished. In fact, it has been observed that if the part 29 to be clamped (figure 2) has a staircase shape and the frontal phase 2 1 of the slider comes stop on this part (before its longitudinal stroke is complete), that the clamping action by pivoting the slide was realized, since as soon as the slide meets resistance, the clutch 16 gives way so that the control axis 3 turns alone, causing by reaction the tilting of said slide.

On peut par ailleurs, modifier la hauteur de bridage du coulisseau en surélevant la semelle d'appui 1 à l'aide de cales intercalaires 30 telles que celles illustrées en figure 7. Ces cales ont sensiblement la forme de la semelle d'appui 1 et comportent un embrèvement 31 et une découpe 32 servant respectivement à recevoir l'organe de fixation 7 destiné à immobiliser la semelle d'appui 1 sur son support et,d'autre part (figure 2),un doigt effacable 33 logé dans un trou borgne 34 de la semelle et soumis à la pression d'un ressort 35 travaillant en extension. Ainsi avant la fixation de la semelle d'appui 1 sur son support,on peut disposer sous sa face inférieure une ou plusieurs cales 30, d'épaisseurs différentes, celles-ci étant immobilisées longitudinalement et transversalement par les organes 7 et 33 positionnés dans les découpes 31 et 32 de ces cales 30.It is also possible to modify the clamping height of the slide by raising the support sole 1 with the aid of spacers 30 such as those illustrated in FIG. 7. These spacers have substantially the shape of the support sole 1 and include a recess 31 and a cutout 32 respectively serving to receive the fixing member 7 intended to immobilize the support sole 1 on its support and, on the other hand (FIG. 2), an erasable finger 33 housed in a blind hole 34 of the sole and subjected to the pressure of a spring 35 working in extension. Thus, before fixing the support sole 1 to its support, one or more shims 30, of different thicknesses can be placed under its underside, these being immobilized longitudinally and transversely by the members 7 and 33 positioned in the cutouts 31 and 32 of these shims 30.

La fixation de l'organe 7 d'ancrage de la semelle d'appui 1 est rendue possible par le fait que le coulisseau 2 comporte lui aussi un perçage 36 le traversant de part en part, celui-ci étant amené en alignement de l'organe de fixation 7 lorsque le coulisseau 2 est dans la position rétractée P de la figure 1. On observe en effet en figure 4 que la tête de la vis 7 à six pans creux est accessible par un outil en raison non seulement du perçage 36 du coulisseau mais également de la forme découpée du pontet 23.The fixing of the member 7 for anchoring the support sole 1 is made possible by the fact that the slider 2 also has a bore 36 passing right through it, the latter being brought into alignment with the fastening member 7 when the slider 2 is in the retracted position P of FIG. 1. It can be seen in FIG. 4 that the head of the hexagon socket screw 7 is accessible by a tool not only because of the bore 36 of the slide but also of the cut shape of the trigger guard 23.

Afin d'éviter que la position excentrée du coulisseau par rapport à l'axe de commande 3 provoque par gravité son plongeon vers le bas et par conséquent gène le déplacement longitudinal dudit coulisseau, il est prévu dans la semelle d'appui 1 des pions de relevage 37 logés dans des perçages borgne 38 et soumis à l'action de ressorts 39, ces pions prenant appui sous le coulisseau et étant destinés par conséquent à maintenir celui-ci dans une position sensiblement relevée.To prevent the eccentric position of the slide relative to the control axis 3 causes by gravity its plunge downwards and consequently hinders the longitudinal displacement of said slide, there is provided in the support sole 1 lifting pins 37 housed in blind holes 38 and subjected to the action of springs 39, these pins taking support under the slide and therefore being intended to maintain the latter in a substantially raised position.

Afin de limiter la course verticale de l'arbre de commande 3 par rapport à la douille filetée 5 de la semelle d'appui l,il est prévu de fixer sur l'une des faces latérales de la semelle 1 un indicateur de hausse 40 (figure 5) dont le bord supérieur 41 est replié à angle droit vers l'intérieur du dispositif de manière que lorsque le coulisseau atteint une position excessive il rencontre cette garde 41 qui,même si elle est à ressort, prévient l'opérateur que le coulisseau a atteint sa position maximum de basculement. En effet, si l'inclinaison du coulisseau est excessive,celui-ci aura tendance à déformer l'indicateur de hausse 40 de sorte que le coulisseau 2 en échappant au bec 41 engendrera un cliquetis métallique caractéristique alertant l'opérateur.In order to limit the vertical stroke of the control shaft 3 relative to the threaded sleeve 5 of the support sole l, provision is made to fix an increase indicator 40 on one of the lateral faces of the sole 1 ( Figure 5) whose upper edge 41 is folded at right angles to the interior of the device so that when the slide reaches an excessive position it meets this guard 41 which, even if it is spring-loaded, warns the operator that the slide has reached its maximum tilting position. Indeed, if the inclination of the slider is excessive, it will tend to deform the rise indicator 40 so that the slider 2 by escaping the spout 41 will generate a characteristic metallic rattling alerting the operator.

Ce dispositif peut de par la simplicité de sa construction et de son fonctionnement être utilisé dans de multiples applications puisque fixé sur le dormant,c'est-à-dire sur l'huisserie d'une porte, d'une fenêtre ou sur la partie fixe d'un récipiènt,il peut servir à la fermeture étanche et rigoureuse d'un ouvrant ou d'un couvercle, alors que fixé sur une table de machine outil, il servira au bridage de pièce à usiner en raison du multiplicateur de puissance que constitue le bras de levier formé par le coulisseau. De même il pourrait également servir de loqueteau si on le fixe sur une huisserie de porte ou de fenêtre pour immobiliser une baie vitrée à coulissement axial . Dans ce cas le coulisseau jouerait le rôle de penne grace à son double mouvement axial et angulaire. A cet effet, l'axe de commande peut comporter à son extrémité opposée à sa tête 17 un logement 42 à six pans creux pour permettre l'accessibilité à l'axe 3 des deux côtés du support.This device can, by the simplicity of its construction and its operation, be used in multiple applications since it is fixed on the frame, that is to say on the frame of a door, a window or on the part fixed from a container, it can be used for the tight and rigorous closing of an opening or a lid, while fixed on a machine tool table, it will be used for clamping of workpiece due to the power multiplier that constitutes the lever arm formed by the slide. Similarly, it could also serve as a latch if it is fixed to a door or window frame to immobilize a bay window with axial sliding. In this case the slide would play the role of pin thanks to its double axial movement and angular. To this end, the control shaft may comprise at its end opposite its head 17 a housing 42 with a hexagon socket to allow accessibility to the shaft 3 on both sides of the support.

Bien entendu, on pourra apporter des variantes de réalisation à ce dispositif mais celles-ci ne sortiront pas du cadre de l'invention qui est défini par un coulisseau à commande axiale et angulaire,manoeuvré par un seul et même organe de commande à embrayage,susceptible de céder, dès que le couple de rotation de l'organe de commande est supérieur au couple de frottement de l'embrayage. Le couple résultant de la friction de la bague fendue étant en effet supérieur au couple nécessaire au déplacement longitudinal du coulisseau par l'intermédiaire du doigt 26 , mais insuffisant pour bloquer l'axe 3 dès la fin du déplacement du coulisseau 2.Of course, it is possible to make variant embodiments of this device, but these will not depart from the scope of the invention, which is defined by a slide with axial and angular control, operated by a single and same clutch control member, likely to fail, as soon as the torque of the control member is greater than the friction torque of the clutch. The torque resulting from the friction of the split ring being in fact greater than the torque necessary for the longitudinal displacement of the slider by means of the finger 26, but insufficient to block the axis 3 as soon as the displacement of the slider 2 ends.
