    专利说明:

    The invention relates to a rotary control system for an apparatus. The invention also relates to an electrical cabinet comprising a controllable electrical appliance and such a rotary control system for controlling this electrical appliance. The invention is more particularly applicable to rotary control systems for electrical appliances, such as circuit breakers. In known manner, such systems comprise a rotary control member movable in rotation between predefined positions associated with electrical states separate from the electrical apparatus, for example active and stopped states. For a circuit breaker, for example, these electrical states correspond to the closed state and the open state. Typically, the electrical apparatus is placed inside an electrical cabinet, on a bottom wall of this electrical cabinet. A rotary control handle is placed on a cabinet door, facing the bottom wall, to be accessible and operable from outside the cabinet by a user. This handle is connected to the rotary member, for example by means of a rigid shaft, so that the rotation of the control handle rotates the rotary member between its predefined positions so as to control the electrical apparatus.
    For safety reasons, it is desirable that the rotatable member can be locked in a predefined position, typically its position corresponding to the open or stopped state of the electrical apparatus, when the cabinet door is open. This is particularly useful during maintenance operations during which the appliance is shut down and the cabinet door is open. Indeed, it is necessary to avoid that the electrical device is accidentally restarted, thus putting under stress an electrical installation on which an operator is working.
    Control systems are known in which the handle is lockable to prevent rotation thereof. An example of such a handle is described in patent EP 1 791 149 B1. A disadvantage of these systems is that they are inoperative when the door is open, because the handle is then no longer connected to the rotary member. Locking the handle does not prevent the rotating member is directly maneuvered and therefore the electrical device is returned to its active state.
    It is not always possible to place an additional lockable handle directly on the rotary control member inside the cabinet, as this would complicate the insertion of the rigid shaft of the control handle into the body. rotary.
    Control systems are also known in which a lock is incorporated in the rotary member. This has the disadvantage of increasing the size and complexity of the system. In addition, such a lock is typically usable only by a reduced number of keys specifically associated with this lock, which must therefore be provided to each user of the lock. The manufacture and packaging of such a system for delivery to customers are thus complicated and expensive. It is these disadvantages that the invention intends to remedy more particularly, by proposing a control system of an apparatus provided with a rotary control member with a simplified design and a small footprint and which simply allows locking in a of his positions. For this purpose, the invention proposes a rotary control system for an apparatus, this system comprising: a rotary control member, rotatable about a first fixed axis, between first and second positions, a rotary handle control device, intended to be secured in rotation with the rotary member about the first axis, - a locking device, selectively movable, when the rotary member is in its first position, between: o a locking configuration, in which it prevents the displacement of the rotary member towards its second position, and o a release configuration, in which it allows the displacement of the rotary member towards its second position.
    This system is characterized in that it comprises, in addition, a locking plate, rotatable about the first axis relative to the rotary member, when the rotary member is in its first position, between: o a position lock, wherein a first through-hole of the rotary member is superimposed with a second through-hole of the locking plate, these first and second orifices then forming an opening adapted to receive, a locking tool solidarisant in rotation the organ rotatable with the locking plate about the first axis, and o an unlocking position, wherein the first and second orifices are offset relative to each other and do not together form the opening, and in that the locking plate is configured to switch the locking device between its blocking and releasing configurations as it is moved between its positions, respectively locked and unlocked.
    Thanks to the invention, to lock the rotary member in its first position, it is sufficient to move the locking plate in rotation until the first and second holes are superposed with each other to form the opening. In doing so, during the displacement of the locking plate, the locking device is simply moved to its locking configuration, thus preventing a displacement of the rotary control member. It is then sufficient to insert a locking tool, such as a padlock, through the opening to prevent a rotational movement of the locking plate. The locking device is therefore able to be maintained in its blocking configuration, thus preventing the rotary control member from being moved to its second position.
    In this way, the lock can be achieved simply with a padlock, without it being necessary to incorporate a dedicated lock. The design of the system is thus simplified, as is its manufacture under industrial conditions. In addition, it provides greater flexibility of use because it is the user who brings his own locking tool, any locking tool can be used. On the contrary, in the case of a lock, only the keys previously associated with this lock can be used, which complicates the use when several different users must intervene on the device and that these users are in number greater than the number of keys available.
    According to advantageous but non-obligatory aspects of the invention, such a locking system can incorporate one or more of the following features, taken in any technically permissible combination: the locking device comprises a pin carried by the rotary member, this piece being movable in translation relative to the rotary member, between: an extended position, in which a first end of this pin is received inside a hole provided on a fixed frame of the control system and prevents the rotation of the rotary member, the locking device then being in its locking configuration, and o a retracted position, in which the first end of the pin is outside the hole and allows the rotation of the rotary member, the locking device being then in its release configuration, and a return member exerting on the pawn a return force towards its retracted position, and a z one support, carried by the locking plate and configured to push the pin to its deployed position, by pressing on a second end of the pin opposite the first end, when the locking plate is moved to its locked position. - The bearing area is a plane inclined relative to a main geometric plane of the locking plate. - The return member comprises a spring. - The rotary handle and the rotary member are secured by means of a shaft, while the rotary member comprises a cavity receiving an end of this shaft and a fastener of the shaft to the rotary member and that the locking plate comprises a protective blade which protrudes from the locking plate, the protection blade being shaped to cover the fastener only when the locking plate is in its locked position. - The rotary member comprises a groove formed on one of its outer faces and opening on a volume at least partially defined by an inner wall of the rotary member, while the locking plate comprises a claw which has a retaining portion , the claw being inserted into the groove so that the retaining portion bears on a rear face of a body of the rotary member, the opening thickness of a main portion of the groove being less than the width the retaining portion of the claw to prevent translational movement of the locking plate along the first axis relative to the rotary member. - The groove has a secondary portion having an opening thickness greater than the width of the retaining portion of the claw, the secondary portion defining a mounting position of the locking plate, distinct from the locking and unlocking positions and in which the locking plate is movable in translation relative to the rotary member along the first axis. - The locking plate is shaped to prevent, once the claw is inserted into the groove, a displacement to its mounting position. - The locking plate has a straight portion shaped to abut on the pin when the pin is in its retracted position and when the locking plate is moved to its mounting position.
    According to another aspect, the invention relates to an electrical cabinet comprising a controllable electrical appliance housed inside the cabinet and a rotary control system connected to the electrical apparatus for controlling the electrical apparatus from outside the cabinet. cabinet, the control system being as previously described. The invention will be better understood and other advantages thereof will appear more clearly in the light of the description which follows, of an embodiment of a locking system given solely by way of example and made in reference to the accompanying drawings in which: - Figure 1 is a schematic representation in perspective, in a cutaway view of an electrical cabinet comprising a controllable electrical apparatus and a rotary control system according to the invention; - Figures 2 and 3 are schematic representations, in close views, of a portion of the rotary control system according to the invention for the electrical cabinet of Figure 1; FIG. 4 is a diagrammatic section, in section plane IV of FIG. 2, of a portion of the rotary control system according to the invention; FIG. 5 is a schematic representation, in a rear view, of a locking plate of the rotary control system according to the invention; FIG. 6 is a diagrammatic representation, in broken view, of an additional handle for use in the rotary control system of FIG. 1.
    Figure 1 shows an electrical cabinet 2. The cabinet 2 has a bottom wall 4 which extends substantially in a geometric plane P. The cabinet 2 also has side walls 6, 8 and 10 upper and lower. The walls 6, 8 and 10 extend perpendicular to the geometric plane P. The walls 4, 6, 8 and 10 define a housing L. The cabinet 2 also comprises a door 12 which is movable, reversibly, between a position open, in which the housing L is open towards the outside of the cabinet 2 and a closed position, in which the door 12 closes the housing L. For example, the door 12 is pivotally mounted along an axis which extends parallel to the plane P so that, in its closed position, the door 12 faces the bottom wall 4. For example the door 12 is pivotally mounted by means of a hinge fixed on an outer edge of the one or the other of the side walls 6 or 8. The cabinet 12 here has a parallelepiped-shaped trapezoidal shape. The walls 4, 6, 8 and 10 and the door 12 are, for example, made of metal.
    In this description, unless otherwise stated, the "back face" of an element corresponds to the face of this element which is turned towards the bottom wall 4 and which extends essentially to the plane P. The "front face" of an element is the face of this element which is opposed to its front face and which is turned towards the door 12 when this door is closed. The electrical cabinet 2 further comprises an electrical apparatus 20 which is fixedly disposed inside the housing L on the bottom wall 4. For example, the electrical apparatus 20 is electrically connected to electrical conductors of an electrical circuit to protect and penetrate inside the cabinet 2. To simplify Figure 1, these electrical conductors are not illustrated. The electrical apparatus 20 is switchable, selectively and reversibly, between two distinct electrical states, for example an active state, called "ON" and a stopped state, called "OFF". Here the electrical apparatus 20 is a circuit breaker. The apparatus 20 is switchable between its electrical states by means of a switch incorporated in the apparatus 20 and disposed on a front face 22 of the apparatus 20. The switch is here a rotary switch which is rotates about a fixed axis X1 to switch the electrical apparatus 20 between its electrical states. The axis X1 extends perpendicularly with respect to the geometric plane P. The electrical cabinet 2 further comprises a rotary control system of the apparatus 20, for controlling the switching of the electrical apparatus 20 between its electrical states since the outside of the cabinet 2 when the door 12 is closed. The control system 30 is here fixed on the front face 22 of the apparatus 20 and is mechanically coupled with the switch of the electrical apparatus 20. For this purpose, the control system 30 comprises a rotary control member 32, a locking plate 33 and a fixed frame 34.
    The frame 34 is here fixedly mounted and without degree of freedom on the front face 22 of the apparatus 20. The rotatable member 32 is rotatable, relative to the frame 34, about the axis X1 between first and second stable and distinct positions. Here, the rotary member 32 is rotatably mounted about this axis X1 on the frame 34. The rotary member 32 is described in more detail in the following.
    In this example, the rotary member 32 is here mechanically coupled in rotation with this rotary switch about the axis X1. According to a variant, the switch is a lever, or rocker, displaceable by exerting a force along a direction that extends parallel to the plane P. In this case, the frame 34 advantageously encloses a motion transmission system. which converts the rotation of the rotatable member 32 about the axis X1 in a translational force in the vertical direction to switch the switch.
    The control system 30 further comprises a rotary control handle 36 which is intended to be secured in rotation with the rotary member 32 about the axis X1. The handle 36 is mounted on the door 12, here in front of the member 32.
    The handle 36 comprises a movable portion 38 movable in rotation between two distinct positions around an axis X 2, which extends perpendicular to the door 12, and a fixed base 40 which is fixedly mounted on the door 12. The handle 36 is connected to a coupling 42 secured in rotation about the axis X2 with the mobile part 38.
    In this description, the rotational displacement of the handle 36 refers to the rotational displacement of the movable portion 38.
    When the handle 36 is mounted on the cabinet 2, the axis X2 is parallel with the axis X1. In this example, the axes X1 and X2 are then merged. In a variant, the axes X1 and X2 are not coincidental but offset with respect to each other, for example because the handle 36 is not in front of the member 32. In this case, an appropriate mechanism is used to transmit the movement of the handle 36 towards the member 32.
    The control system 30 further comprises a shaft 44 with a polygonal section mounted to rotate with the rotary member 32. The shaft 44 extends substantially along the axis X1. The shaft 44 makes it possible to rotate the handle 36 with the rotary member 32 when the door 12 is closed. For this purpose, the shaft 44 carries the connector 42 on one of its ends. The coupling 42 is fixedly mounted on the shaft 44 and is selectively disconnectable from the movable portion 38 of the handle 36.
    More specifically, when the door 12 is closed, the connector 42 rotates, around the axis X1, the movable portion 38 of the handle 36 with the shaft 44 and thus with the member 32.
    When the door 12 is in its open position, the axis X2 is no longer aligned with the axis X1. The handle 36 is in a remote position, as is the connector 32. The movable portion 38 of the handle 36 is disconnected from the connector 42. The handle 36 is thus mechanically decoupled from the rotary member 32.
    Alternatively, the connector 42 is carried by the handle 36, and remains integral with the movable portion 38. When the door 12 is open, the shaft 44 disengages the connector 42. The shaft 44 is here fixedly fixedly fixed in rotation with the rotary member 32. For example, the rotary member 32 comprises a cavity 46, polygonal section complementary to that of the shaft 44 and provided on a central portion of the rotary member 32 and wherein one end of the shaft 44 is received. The rotary member 32 comprises a fastener 48, such as a set screw, for fixedly holding the shaft 44 inside the cavity 46 and thus preventing any displacement in translation along the axis X1 tending to move the shaft 44 away from the cavity 46.
    Thus, when the door 12 is open, the shaft 44 remains integral with the rotary member 32.
    In this way, when the door 12 is closed, the rotation of the handle 36 rotates the member 32. Here, the switching of the member 32 between the two positions is done by turning the handle 36 by an angle of 90 ° around the axis of rotation X1.
    The control system 30 further comprises a locking device 50, illustrated in FIGS. 2 and 3. In this example, it is desired to be able to lock the rotary member 32 in its first position, that is to say the one corresponding to in the stopped state of the apparatus 20. For this purpose, when the rotatable member 32 is in its first position, the device 50 is selectively movable between a locking configuration and a release configuration.
    In the blocking configuration, the device 50 prevents the rotational member 32 from moving to its second position. In the release configuration, the device 50 allows the displacement of the rotatable member 32 to its second position. The rotary member 32 has a body 52 whose orthogonal geometric projection in the geometrical plane P has essentially a disc shape. The rotatable member 32 has a ring 54 which defines a through opening 56, or orifice. Here, this ring extends parallel to the plane P.
    Advantageously, the member 32 comprises a mark 58 formed on an edge of the body 52 and which makes it possible to indicate visually the position in which the rotary member 32 is located. For example, the mark 58 has an arrow shape. The frame 34 is then covered with visual indicators which are positioned in such a way that the mark 58 points towards one or the other of these indicators, when the rotary member 32 is in one or other of its positions.
    For example, the ring 54 is formed on a peripheral edge of the body 52, by piercing the body 52.
    The locking device 50 here comprises a pin 60, movable and carried by the member 32, illustrated in FIG. 4. This pin 60 is partially received in a housing 62 formed on the body 52.
    The pin 60 is movable in translation between deployed and retracted positions relative to the member 32 along an axis X3 perpendicular to the plane P and integral with the member 32.
    In the deployed position, a distal end 64 of the pin 60 is received inside a blind hole 66 formed on the frame 34. For example, the pin 60 penetrates inside this hole for a length of minus 5 mm or even 8 mm. Thus, the pin 60 prevents the rotation of the rotary member 32 about the axis X1 relative to the frame 34. The locking device 50 is then said to be in its blocking configuration.
    In its retracted position, the distal end 64 of the pin 60 is outside the hole 66, for example by being retracted inside the housing 62. Due to the absence of the pin 60 in the hole 66, the rotary member 32 is free to move in rotation about the axis X1 relative to the frame 34. The locking device 50 is then said to be in its release configuration.
    The device 50 further comprises a resilient return member 68 exerting on the pin 60 a return force towards its retracted position. Here, the return member 68 is housed inside the housing 62 being fixed on the one hand to an inner wall of the housing 62 and on the other hand to the pin 60. For example, the return member 68 is a helical spring.
    The pin 60 here comprises a body of substantially cylindrical shape with a circular base and which extends along the axis X3. The point 60 has, on an end 70 opposite to the distal end 64, a head 72 formed of a frustoconical portion 74 and an end portion 76. The portion 74 is placed between the body of the peg 60 and the portion 76 and here has a truncated cone shape of axis X3. The outer walls of this portion 74 have an angle with respect to the axis X3 which is for example 45 °. The pin 60 is here made of metal. The end portion 76 here has a rounded shape, for example a half-sphere. The housing 62 here has a cylindrical shape of axis X3 with an internal diameter greater than the diameter of the cylindrical body of the pin 60.
    In this example, the rotating member 32 is made of metal, for example in a copper alloy, zinc and aluminum, which gives it a satisfactory hardness and rigidity.
    The locking plate 33 is rotatable about the axis X1 relative to the rotatable member 32. More specifically, when the rotatable member 32 is in its first position, the plate 33 is movable between locking positions and unlocking by rotation around the axis X1.
    Plate 33 is configured to switch blocking device 50 to its blocking position as it is moved from its unlocked position to its locked position. Similarly, plate 33 switches blocking device 50 from its blocking configuration to its release configuration as it is moved from its locked position to its unlocked position.
    The plate 33 here has a substantially planar shape and extends parallel to the plane P, when it is mounted within the system 30. The plate 33 has a central bore in the center of which passes the axis X1. Thus, the plate 33 is arranged coaxially with the rotary member 32. In this example, the central bore is traversed by the portion of the rotary member 32 which carries the cavity 46. The rear face of the plate 33 is turned towards the front face of the organ 32.
    The plate 33 further comprises a ring 82 which defines a through hole 84, for example formed by drilling in the vicinity of an outer edge of the plate 33. This orifice 84 opens on the front and rear faces of the plate 33. The ring 82 extends in the same geometric plane as the ring 54, here parallel to the plane P.
    When the rotary member 32 is in its first position and the plate 33 is in its locking position, as shown in Figure 3, the orifices 56 and 84 are superimposed with each other and form an opening 86 which is capable of receiving, by insertion through this opening 86, a locking tool adapted to rotate the rotary member 32 with the locking plate 33 about the axis X1. For example, this lock tool is a lock. In FIG. 3, a locking tool is shown schematically by the line 88, which represents the handle of a padlock inserted through the opening 86.
    The orifices 56 and 84 are said to be superposed when the orifices 56 and 84 have at least 30%, preferably at least 50%, of their area in common. Preferably, the opening 86, when formed, has an area greater than or equal to 0.5 cm 2. Advantageously, the opening 86 has a disc shape with a diameter greater than or equal to 0.5 cm 2, preferably at 1 cm, more preferably at 2 cm. Thus, the known locking tools, such as clamps or padlocks commonly used by electrical maintenance operators, can be inserted through the opening 86.
    In the unlocking position, the orifices 84 and 56 are angularly offset relative to each other about the axis X 1 and do not form the opening 86, as illustrated in FIG. 2. For example, less 20% or 15% or 10% of the area of the orifice 84 is superimposed with the area of the orifice 56. In the example, the surfaces of the orifices 56 and 84 are not superimposed at all.
    The plate 33 has a bearing zone 100 which is shaped to move the pin 60 to its extended position, by pressing on the proximal end 70 of the pin 60, when the plate 33 is moved from its unlocked position to its locked position.
    In this example and as visible in FIG. 4, the bearing zone 100 comprises an inclined portion 102, or inclined plane, and straight portions 104 and 106. The bearing zone is here arranged opposite the pin 60, on an outer periphery of the plate 33. The portion 102 is projecting with respect to a geometric plane P2 in which the plate 33 essentially extends, this plane P2 forming a main plane of the plate 33. The inclined portion 102 of the plate 33 extends along a geometric plane P3 which forms with the geometric plane P2 an angle a. The angle α is for example between 30 ° and 60 ° and preferably between 40 ° and 50 °. In this case, the angle a is equal to 45 °. The angle a is preferably chosen as a function of the angle of inclination of the walls of the frustoconical portion 74 of the pin 60. When the locking plate 33 is in configuration mounted within the control system 30, the plane P2 is parallel on the plane P.
    In this example, the orthogonal projection of the portion 102 in the plane P2 extends substantially in a circular arc, here following the periphery of the plate 33. The portion 102 extends here between first and second angular positions, away from the plane P2 from the first angular position to the second angular position. These angular positions are here defined with respect to the geometric center of the plate 33. The angle between these first and second angular positions, measured in the plane P2, depends on the stroke of the pin 60 and the angle a.
    The parts 102, 104 and 106 are in contact with each other and are for example formed integrally and with the plate 33. For example, the parts 102, 104 and 106 are formed by localized stamping of the plate 33 Alternatively, the piece 33 is formed by molding. The portion 104 extends substantially parallel to the plane P2 and connects the portion 102 with the portion 106.
    The portion 106 is projecting with respect to the plane P2, with an angle with respect to this plane P2 strictly greater than 45 °, preferably greater than or equal to 55 ° or 75 °, or, alternatively, perpendicular to the plane P2.
    The portions 102, 104 and 106 define a housing which receives the end 70 of the pin 60 when in its retracted position. The angle a is measured on the side of the portion 102 facing the interior of the housing. The portion 76 of the pin 60 then abuts against the portion 104 when the plate 33 is in its unlocked position, because of the return force E68 exerted by the return member 68. Thanks to the hemispherical shape of the portion 76, the contact surface between the proximal end 70 of the pin 60 and the portion 104 of the plate 33 is reduced, which limits the frictional forces between the plate 33 and the pin 60 when the plate 33 is moved. relative to the rotary member 32.
    The portion 102 moves the pin 60 from its retracted position to its deployed position when the plate 33 is moved from its unlocked position to its locked position by turning the plate 33 relative to the member 32 in the direction represented by the arrow F1 to FIG. 4. The portion 102 forms a cam against which the end portion 76 slides. As the plate 33 moves relative to the rotary member 32, the portion 102 exerts a thrust force E102 on the counter 60 directed along the X3 axis. This effort E102 opposes and surpasses the force E68 exerted by the return member 68 on the pin 60.
    When the rotatable member 32 is in its first position, the pin 60 is in front of the hole 66 and thus slides relative to the housing 62 along the axis X3, so that the end 64 enters gradually to the inside the hole 66 until the pin 60 is in its first deployed position. Then, the plate 33 covers the head 72 of the pin and prevents any subsequent movement of the pin 60 relative to the housing 62.
    On the contrary, if the rotational member 32 is not in its first position, then the pin 60 can not move to its deployed position. If the plate 33 is rotated relative to the rotatable member 32 to exert the force E102 as described above, the pin 60 moves but its distal end 64 abuts against the frame 34. then not possible to continue moving the plate 33 to its locked position. Thus, as long as the rotary member 32 is not its first position, the plate 33 can not be moved to its locking position, although here it can however move slightly with respect to the rotary member 32 of the makes the length of part 104.
    The portion 106 prevents, for its part, a displacement of the plate 33 in an opposite direction as explained in the following.
    The length of the portion 102 is advantageously chosen such that the rotational movement of the plate 33 between its unlocked and locked positions is sufficient to completely move the pin 60 from its retracted position to its deployed position.
    Thus, when the opening 86 is formed, the pin 60 is completely in its retracted position. The locking tool 88 is inserted into the opening 86, the plate 33 is integral in rotation with the member 32 about the axis X1 and the pin can not be moved from the retracted position, in which it is located immobilizing the rotary member 32 in its first position.
    Advantageously, the plate 33 comprises a protective blade 120 which protrudes from the outer face of the plate 33. The blade 120 is shaped to cover the outside of the part 48 only when the plate 33 is in its locked position, as illustrated in Figure 3. For example, the blade 120 extends projecting along an axis parallel to the axis X1. The blade 120 blocks access to the part 48 thus preventing disassembly of the shaft 44. Such disassembly is undesirable because it would allow a user to separate the constituent elements of the system 30 and thus bypass the lock provided. by the body 88.
    When the plate 33 is in the unlocked position, the blade 120 is spaced from the fastener 48 and allows access to this part, as shown in FIG.
    The blade 120 is thus positioned at a predefined location so as to cover the fastener 48 only when the plate 33 is in its locking position. For example, the angular offset, measured parallel to the plane P and around the axis X1, between the protection blade 120 and the geometric center of the orifice 84 is the same as the angular offset, measured in the same way, between the fastener 48 and the geometric center of the orifice 56.
    Advantageously, the rotary member 32 comprises a groove 130 formed on one of its outer faces and opening on a volume at least partially defined by an inner wall of the rotary member 32, as shown in Figure 5. Here, the groove 130 is a slot which passes through the body 52 and which opens on either side of the body 52 on opposite sides of the body 52. The groove 130 comprises a main portion 132 and a secondary portion 134. The groove 130 s' extends here parallel to the geometric plane P.
    The main portion 132 has a first opening thickness E1, measured along a radial axis of the body 52 parallel to the plane P between opposite edges of this main portion of the groove 130. The secondary portion has a second radial thickness E2 measured from similarly, parallel to the plane P between opposite edges of this secondary portion 134. The thickness E2 is greater than the thickness E1.
    The plate 33 comprises, in turn, a claw 136 protruding from the rear face of the plate 33. The claw 136 is slidably mounted inside the groove 130 when the plate 33 is in a assembled state with the control system 30. More specifically, the claw 136 is inserted inside the groove 130 so that a retaining portion 138 of the claw 136 is supported on the rear face of the body 52. The portion 138 has a width E3 which is greater than the opening thickness E1 of the main portion 132 of the groove 130. Thus, the portion 138 prevents any displacement in translation of the plate 33 relative to the rotary member 32 along the axis X1. When the plate 33 moves between the locked and unlocked positions, the claw 136 moves only along the main portion 132 of the groove 130.
    In this example, the plate 33 has three claws 136 and the member 32 has three grooves 130 identical to each other and each receiving a corresponding claw 136. The claws 136 and the grooves 130 are preferably regularly distributed around the axis X1, at 120 ° in the example
    The abutment 134 defines a mounting position of the plate 32 separate from the locking and unlocking positions. In this mounting position, the plate 33 is displaceable in translation relative to the rotary member 32 along the axis X1 to insert the or each claw 136 in the corresponding groove 130.
    Advantageously, the portion 106 of the zone 100 prevents the plate 33 from returning to its mounting position once the claw 136 is inserted into the groove 130. Because this portion 106 protrudes with respect to the plane P2 as described above, and therefore parallel to the axis X3, it does not allow to move in translation the pin 60 from its retracted position to its deployed position by turning the plate 33, in the manner of what is achieved with the inclined portion 102 .
    An example of use of the control system 30 will now be described with reference to Figures 1 to 5.
    Initially, the plate 33 is in a disassembled state of the system 30. The pin 60 and the return member 68 are previously mounted in the device 30. The plate 33 is first mounted on the rotary member 32, for example in threading the portion of the rotatable member 32 carrying the cavity 46 through the central orifice 80 of the plate 33. The plate 33 is rotated so that the claw 136 is disposed opposite the secondary portion 134 of the groove 130. The plate 33 is then in its mounting position. The plate 33 is then pushed towards the member 32 along the axis X1. In doing so, the claw 136 enters the groove 130. Simultaneously, the proximal end 70 of the pin 60 is pushed by the plate 33, which causes a movement of the peg 60 in its retracted position.
    Then, the plate 33 is rotated relative to the rotary member 32 so as to bring the plate 33 into its unlocking position, as shown in FIG. 4. For example, the plate 33 is turned in the direction illustrated by FIG. F1 arrow during this rotation, the claw 136 leaves the secondary portion 134 to penetrate inside the main portion 132 of the groove 130. Simultaneously, the plate 33 moves relative to the pin 60 until the housing defined by the portions 102, 104 and 106 of the plate 33 is brought opposite the proximal end 70 of the pin 60. Then, the plate 33 is no longer in contact with the end 70 and is no longer opposed to the E68 force exerted by the member 68. The pin 60 is pushed to its retracted position until it comes into abutment against the right portion 104 of the plate 33. Due to the right portion 106, it is no longer possible to impose on the plate 33 a rotational movement in s reverse all to return to the mounting position. Thus, it is avoided that the plate 33 can be spaced along the axis X1 of the rotary member 32 when it is in the locking position, which would have the effect of rendering inoperative the locking exerted by the locking device 50 on the rotary member 32. If this occurred, the rotatable member 32 could then be manipulated, accidentally or maliciously, to switch the electrical apparatus 20 to its active state in an unauthorized manner.
    Once the plate 33 is in its unlocked position, the blocking device is in its release configuration. The rotary member 32 is freely movable between its first and second positions to switch the electrical device between its active and off states. For example, the door 12 is closed and the control of the apparatus 20 is effected by means of the handle 36 from the outside of the cabinet 2.
    Then, to lock the rotary member 32 in its first position, the door 12 is open. The plate 33 rotates about the axis X1 relative to the rotary member 32, for example manually, until the orifices 84 and 56 overlap and form the opening 86. Simultaneously, the bearing zone 100 moves until the inclined portion 102 comes into contact with the head 72 of the pin 60, exerting the effort E102 as described above. The progressive rotation of the plate 33 moves the pin 60 towards its deployed position in the hole 66. At the end of the rotation, the plate 33 is in its locked position, as shown in FIG. 3. The pin 60 is in its position. deployed position and prevents any rotational movement of the rotatable member 32 relative to the frame 34.
    This therefore prevents switching the electrical apparatus 20 to its active electrical state. In this locked position, the orifices 56 and 84 are superimposed with each other and together form the opening 86. A user can easily insert a locking member 88 in the shutter 86. As long as this member 88 is now, the plate 33 is kept in its locked position making it impossible to move relative to the member 32.
    When a user removes the locking member 88, the plate 33 is again movable relative to the rotary member 32. The plate 33 is then rotated in an opposite direction of rotation and the zone 100 moves in a direction of rotation. opposite to the one illustrated by the arrow F1. Under the force E68, the pin 60 moves to its retracted position until it abuts against the portion 104. At the same time, the orifices 84 and 56 move away from each other making the insertion of a locking tool for interconnecting the plate 33 and the rotatable member 32. The plate 33 is then in its unlocked position, as shown in Figure 2. The rotatable member 32 is freely movable to its second position to switch the machine. electrical apparatus 20 to its active state.
    Advantageously, the control system 30 includes an additional control handle 200, as illustrated only in FIG. 6. The handle 200 is mounted on the shaft 44 inside the cabinet 2. This handle 200 is distinct. of the handle 36. The handle 200 is configured to facilitate a rotational movement of the shaft 44 about the axis X1 by a user. It also prevents this rotation is accidental.
    The handle 200 comprises an outer body 202 provided with a central bore 204 allowing the passage of the shaft 44. The handle 200 further comprises a movable portion 206 displaceable in translation relative to the body 202 along an integral Y1 axis of the outer body 202 and perpendicular to the axis X1. The movable portion 206 has an outer portion 208 and jaws 210 defining a housing 212.
    The movable portion 202 is movable, along the axis Y1, between a first position in which the shaft 44 is remote from the jaws 210 and is outside the housing 212, and a second position in which the shaft 44 is enclosed by the jaws 210 inside the housing 212.
    The handle 200 further comprises a return member 214, such as a spring, configured to exert a return force on the movable portion 206 along the axis Y1 to bring the movable portion 206 to its first position.
    When the movable portion 206 is in its first position, the handle 200 is rotatable relative to the shaft 44 about the axis X1. Thus the setting in motion of the handle 200 does not cause corresponding rotation of the shaft 44.
    Advantageously, the handle 200 still exerts a non-zero force on the shaft 44, to prevent the handle 200 from sliding freely on the shaft 44, which allows to maintain it at a desired location by a user.
    When the movable portion 206 is in the second position, the handle 200 is rotationally integral with the shaft 44 about the axis X1, thanks to the action of the jaws 210 on the shaft 44. A rotating movement of the handle 200 therefore causes a corresponding rotational movement of the shaft 44 about the axis X1.
    The passage between the first and second positions of the movable portion 206 is effected by exerting pressure on the outer portion 208 along the Y1 axis. When this pressure is sufficiently high, it opposes the return force by the return member 214 and causes displacement of the movable portion to its second position. When no pressure is exerted on the outer portion 208, the movable portion 206 returns to its first position under the effect of the return member 214.
    Thus, the handle 200 can be used only when a force is applied on the outer portion 208. In this way, it is ensured that the rotation of the handle 200 is the result of a deliberate action on the part of a user and not an accidental movement exerted on the handle 200.
    The handle 200 can be implemented independently of the control system 30 described above.
    Alternatively, the apparatus 20 is not an electrical apparatus. It can be a controllable valve.
    The different variants and different embodiments of the invention can be combined with each other to form new embodiments of the invention.
