Description

L'invention est relative à un dispositif de cadenassage d'une manette de manoeuvre d'un disjoncteur miniature à boîtier moulé, ayant des orifices ménagés sur la face latérale de la lumière de débattement de la manette, dans lesquels peuvent être introduites les extrémités recourbées en équerre d'un organe de verrouillage en forme d'épingle à cheveux.The invention relates to a padlocking device for an operating handle of a miniature circuit breaker with molded housing, having orifices provided on the lateral face of the clearance light of the lever, into which the curved ends may be introduced. at right angles to a hairpin-shaped locking member.

Le brevet français 2424619 décrit un dispositif de cadenassage du genre mentionné, faisant usage d'un coulisseau pour bloquer les branches de l'épingle à cheveux en position montée sur le disjoncteur. Un tel dispositif doit être parfaitement inviolable et la présente Invention a pour but de perfectionner ce dispositif, notamment en vue d'éviter toute cassure des oreilles qui délimitent la lumière de débattement de la manette du disjoncteur et portent les orifices qui reçoivent les extrémités des branches de l'épingle à cheveux. Une telle rupture peut résulter de l'appui du dispositif de cadenassage sur la manette abaissée et de l'effet de levier qui en résulte.French patent 2424619 describes a lockout device of the kind mentioned, making use of a slide to lock the branches of the hairpin in the position mounted on the circuit breaker. Such a device must be perfectly inviolable and the present invention aims to improve this device, in particular with a view to avoiding breakage of the ears which delimit the clearance light of the handle of the circuit breaker and carry the orifices which receive the ends of the branches of the hairpin. Such a break can result from the support of the padlocking device on the lowered lever and the resulting leverage.

Le dispositif de cadenassage selon l'invention est caractérisé en ce que ladite épingle est montée à coulissement sur une embase ayant une pièce de blocage en forme de coin inséré en position active entre les branches de l'épingle à cheveux pour maintenir ces branches en position écartée de maintien dans lesdits orifices, un levier de commande articulé sur l'embase coopérant avec ladite épingle.The padlocking device according to the invention is characterized in that said pin is slidably mounted on a base having a wedge-shaped blocking piece inserted in the active position between the branches of the hairpin to hold these branches in position held apart in said holes, a control lever articulated on the base cooperating with said pin.

L'épingle à cheveux est guidée à coulissement sur l'embase, qui porte le coin maintenant les branches de l'épingle écartées en position de verrouillage de la manette. L'embase en forme de L libère les deux positions stables de la manette, empêchant tout effet de levier susceptible de casser les oreilles délimitant la lumière de débattement. L'épingle à cheveux est parfaitement maintenue et guidée ce qui évite tout risque de fraude.The hairpin is slidably guided on the base, which carries the corner holding the branches of the pin apart in the locking position of the handle. The L-shaped base frees the two stable positions of the joystick, preventing any leverage likely to break the ears delimiting the clearance light. The hairpin is perfectly maintained and guided, which avoids any risk of fraud.

L'embase porte à pivotement un levier de commande, dont l'une des extrémités est conformée en bec d'accrochage de l'anse de l'épingle à cheveux. L'autre bras d'actionnement du levier peut être immobilisé en position de verrouillage en appui sur l'embase par un cadenas, dont la maille traverse un oeillet porté par l'embase. Cet oeillet s'étend dans le plan de débattement de la manette du disjoncteur. le cadenas venant se placer dans un plan perpendiculaire. Cette disposition autorise un pivotement du cadenas vers une position horizontale facilitant le passage par un plastron de recouvrement des disjoncteurs.The base pivotally carries a control lever, one of the ends of which is shaped as a hooking spout for the handle of the hairpin. The other lever actuating arm can be immobilized in the locked position by pressing on the base by a padlock, the mesh of which passes through an eyelet carried by the base. This eyelet extends in the deflection plane of the circuit breaker handle. the padlock coming to be placed in a perpendicular plane. This arrangement allows the padlock to pivot to a horizontal position facilitating passage through a circuit-breaker cover plate.

Sur les figures, un disjoncteur miniature à boîtier mouléIn the figures, a miniature molded case circuit breaker

(10) présente sur la face frontale (12) d'une partie (14) en saillie, une manette (16) de manoeuvre manuelie. La manette (16) se débat dans une lumière (18) ménagée dans la face frontale (12) et peut occuper deux positions extrêmes correspondant respectivement à la position ouvert et fermé du disjoncteur (10). Les faces latérales (20 - 22) de la lumière (18) présentent dans leur partie médiane des orifices (24 - 26) permettant usuellement le passage d'un fil de plombage interférant avec la trajectoire de pivotement de la manette (16). Les orifices (24- 26) sont alignés et permettent la mise en place d'un fil de plombage ou d'un organe de verrouillage décrit ci-dessous. la manette (16) étant dans l'une quelconque des deux positions extrêmes.(10) has on the front face (12) of a projecting part (14), a lever (16) for manual operation. The lever (16) struggles in a light (18) formed in the front face (12) and can occupy two extreme positions corresponding respectively to the open and closed position of the circuit breaker (10). The lateral faces (20 - 22) of the light (18) have in their middle part orifices (24 - 26) usually allowing the passage of a sealing wire interfering with the pivoting trajectory of the lever (16). The holes (24-26) are aligned and allow the installation of a sealing wire or a locking member described below. the handle (16) being in any one of the two extreme positions.

La présence du fil de plombage ou de l'organe de verrouillage empêche une commande manuelle de fermeture ou d'ouverture du disjoncteur miniature (10).The presence of the sealing wire or the locking member prevents manual closing or opening of the miniature circuit breaker (10).

Le dispositif de cadenassage désigné par le repère général (28) comporte une pièce de verrouillage en forme d'épingle à cheveux (38), à extrémités (40 - 42) repliées en équerre. L'épingle (38) est en un matériau èlastique, par exemple en acier inoxydable, sollicitant les branches (44 -46) en position rapprochée. Le diamètre des orifices (24 - 26) et la longueur cumulée des parties recourbées (40 - 42) permettent une introduction de l'épingle (38) dans les orifices (24-26).The padlocking device designated by the general reference (28) comprises a locking piece in the form of a hairpin (38), with ends (40 - 42) folded at right angles. The pin (38) is made of an elastic material, for example stainless steel, urging the branches (4 4 -46) in the close position. The diameter of the orifices (24 - 26) and the cumulative length of the curved portions (40 - 42) allow the pin (38) to be introduced into the orifices (24-26).

Un dispositif de cadenassage de ce type est décrit dans le brevet français précité, auquel le lecteur se reportera avantageusement pour de plus amples détails.A lockout device of this type is described in the aforementioned French patent, to which the reader will advantageously refer for further details.

L'épingle (38) est montée à coulissement, selon l'invention, sur une embase (30), présentant des rainures de guidage (32, 34), ménagées sur le bord d'une saillie en forme de coin (36), inséré entre les branches (44,46). LeThe pin (38) is slidably mounted, according to the invention, on a base (30), having guide grooves (32, 34), formed on the edge of a wedge-shaped projection (36), inserted between the branches (44,46). The

coin (36) constitue la branche courte de l'embase (30), en forme de l, la partie amincie du coin (36) étant orientée du côté ouvert de l'épingle (38). Sur un axe (48) de l'embase (30) est monté à pivotement un levier (50), dont le bras court est agencé en bec (52) d'accrochage de l'anse de l'épingle (38). Un pivotement du levier(50) provoque un coulissement de l'épingle (38) dans les rainures (32, 34) et un écartement ou rapprochement des branches (44,46) sous l'action du coin (36) et de l'élasticité de l'épingle (38). Dans la position active, représentée à la figure 1, le levier (50) est en appui de l'embase (30), le bec (52) ayant déplacé l'épingle (38) vers le haut sur la figure 1, en provoquant l'écartement des branches (44,46) par le coin (36) qui vient au niveau des extrémités recourbées (40, 42). L'épingle (38) est bloquée en position de verrouillage et elle empêche, en coopération avec le coin (36), tout déplacement de la manette (16) vers le milieu de la lumière (18), c'est à dire toute manoeuvre du disjoncteur (10).wedge (36) constitutes the short branch of the base (30), l-shaped, the thinned part of the wedge (36) being oriented on the open side of the pin (38). On a shaft (48) of the base (30) is pivotally mounted a lever (50), the short arm of which is arranged as a spout (52) for hooking the handle of the pin (38). A pivoting of the lever (50) causes a sliding of the pin (38) in the grooves (32, 34) and a separation or bringing together of the branches (44, 4 6) under the action of the wedge (36) and the elasticity of the pin (38). In the active position, shown in Figure 1, the lever (50) is in support of the base (30), the spout (52) having moved the pin (38) upwards in Figure 1, causing the spacing of the branches (44,46) by the wedge (36) which comes at the level of the curved ends (40, 42). The pin (38) is locked in the locked position and it prevents, in cooperation with the wedge (36), any movement of the handle (16) towards the middle of the light (18), that is to say any operation of the circuit breaker (10).

L'ors d'un pivotement du levier (50) vers la position relevée, écartée de l'embase (30), le crochet (52) autorise ou provoque le coulissement de l'épingle (38) vers le bas sur la figure 2 dans laquelle le coin (36) vient se loger vers le fond de l'anse de l'épingle. en autonsant un rapprochement des branches (44, 46) notamment par l'élasticité propre de l'épingle (38). Les extrémités recourbées (40. 42) sortent des orifices (24, 26) et permettent l'enlèvement du dispositif de cadenassage (28).When the lever (50) pivots towards the raised position, spaced from the base (30), the hook (52) authorizes or causes the sliding of the pin (38) downwards in FIG. 2 in which the corner (36) is housed towards the bottom of the handle of the pin. by autonsant a reconciliation of the branches (44, 46) in particular by the own elasticity of the pin (38). The curved ends (40, 42) exit from the orifices (24, 26) and allow the removal of the padlocking device (28).

L'embase (30) porte un oeillet (54), qui traverse une lumière (56), ménagée dans le levier (50), en position rabattue de ce dernier sur l'embase (30). La maille (58) d'un cadenas (60) traverse l'oeillet (54) lors d'un cadenassage et le cadenas (60) empêche bien entendu tout relèvement du levier (50). L'oeillet (54) s'étend dans le plan de débattement de la manette (16) et le cadenas (60) peut être pivoté vers le haut horizontalement pour le passage à travers l'ouverture d'un plastron (non représenté).The base (30) carries an eyelet (54), which passes through a lumen (56), formed in the lever (50), in the folded position of the latter on the base (30). The mesh (58) of a padlock (60) crosses the eyelet (54) during padlocking and the padlock (60) of course prevents any raising of the lever (50). The eyelet (54) extends in the plane of movement of the lever (16) and the padlock (60) can be pivoted upwards horizontally for passage through the opening of a faceplate (not shown).

L'embase (30) présente du côté du disjoncteur (10) un évidement (62), dans lequel vient se loger la manette (16) en position abaissée, représentée en trait discontinu sur la figure 3. Dans cette position le dispositif de cadenassage prend appui sur la face avant du disjoncteur et non sur la manette. Il en est de même dans la position relevée de la manette (16).The base (30) has a recess (62) on the side of the circuit breaker (10), in which the handle (16) is housed in the lowered position, shown in broken lines in FIG. 3. In this position the padlocking device is supported on the front face of the circuit breaker and not on the handle. It is the same in the raised position of the handle (16).

La mise en oeuvre de ce dispositif de cadenassage est analogue à celle décrite dans le brevet précité. Dans la position relevée du levier (50) le dispositif (28) peut être mis en place sur le disjoncteur par insertion des extrémités recourbées (40, 42) dans les orifices (24, 26) que la manette (16) soit abaissée ou relevée. Le pivotement du levier (50) vers l'embase (30) fait coulisser l'épingle (38) vers le haut et le coin (36) force à écartement les branches (44, 46) en faisant pénétrer et en verrouillant les extrémités (40. 42) dans les orifices (24. 26). La mise en place du cadenas (60) verrouille le levier (50). Une opé. ration inverse permet l'enlèvement du dispositif de verrouillage (28).The implementation of this lockout device is similar to that described in the aforementioned patent. In the raised position of the lever (50) the device (28) can be put in place on the circuit breaker by inserting the curved ends (40, 42) in the orifices (24, 26) whether the lever (16) is lowered or raised . The pivoting of the lever (50) towards the base (30) causes the pin (38) to slide upwards and the wedge (36) forces the branches (44, 46) to move apart, making the ends penetrate and lock ( 40. 42) in the holes (24. 26). Putting the padlock (60) in place locks the lever (50). An opera. reverse ration allows removal of the locking device (28).

L'invention est bien entendu nullement limitée au mode de mise en oeuvre plus particulièrement décrit.The invention is of course in no way limited to the embodiment more particularly described.
