Definitions

  • 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.
  • 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.
  • the padlocking device 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.
  • 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.
  • 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.
  • 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.
  • the presence of the sealing wire or the locking member prevents manual closing or opening of the miniature circuit breaker (10).
  • 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).
  • the 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).
  • 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).
  • a lever (50) 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).
  • 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).
  • 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).
  • 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).
  • this lockout device is similar to that described in the aforementioned patent.
  • the device (28) 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).
