Locking control device for leaf

The present invention relates to the field of doors, windows, French windows or other types of door leaves.

More specifically, it relates to a locking control device for an opening door leaf, comprising a rod adapted to be slidably mounted in a longitudinal direction on said leaf; at least one bolt secured to the rod; and a primary actuator adapted to be mounted operatively on said leaf so as to control in translation the rod in a first direction of movement in said longitudinal direction between a locking position in which said bolt is adapted to cooperate with a strike to maintain the leaf in the closed position and an unlocking position.

Document FR 536 991 already discloses locking control devices of this type in which the primary actuator consists of a lever that can be pivotally mounted on the leaf around a pivot axis parallel to the plane of the leaf. and perpendicular to the longitudinal direction of the rod. The lever has a spherical shaped head adapted to be housed in an opening formed in the rod. The rod has a locking end constituting a bolt which is adapted to engage in a hole of a keeper secured to the frame of the leaf. These known devices also comprise a handle adapted to be slidably mounted in the longitudinal direction of the rod on the leaf and to cooperate with the lever so as to urge the latter pivotally.

Thus, according to these known devices, the lever is operated via the handle so that the head of the lever controls in translation the rod to move the rod between a locking position in which the locking end is adapted to cooperate with the hole of the strike to maintain the leaf in the closed position and an unlocking position.

A disadvantage of these known devices is that the length of the rod must be imperatively adapted to the size of the leaf in the longitudinal direction of the rod, the locking end of the rod to exceed one edge of the leaf transverse to the direction longitudinal so as to cooperate with the hole of the striker when the rod is in the locking position. As a result, the same rod can not be indifferently mounted on leaves having different dimensions in the longitudinal direction. Thus, it is difficult to produce these known devices as standard elements.

The present invention proposes to substantially remedy this disadvantage.

More particularly, a locking control device for an opening door leaf according to the present invention is characterized in that the rod comprises a plurality of rod fastening elements defined along said rod, in that the control in translation of the rod is made using a control finger, which is adapted to be biased by a maneuver of the primary actuator, and which comprises at least one control finger securing element adapted to secure the control finger with the bead wire by cooperation with one of said bead securing elements, and in that said bolt comprises at least one bolt securing element adapted to secure the bolt with the bead wire by cooperation with another of said bead securing elements.

Thanks to the present invention, the locking device comprises at least one bolt separate from the rod and which is adapted to be secured to the rod along the latter. It is understood that it is thus not necessary that one end of the rod exceeds an edge of the leaf transverse to the longitudinal direction so that the bolt is adapted to cooperate with a striker when the rod is in the locking position . As a result, the length of the bead wire does not have to be adapted to the dimension of the leaf in the longitudinal direction, so that the rod of a device according to the invention can be indifferently mounted on leaves having different dimensions. in the longitudinal direction, which facilitates the standardization of the device and reduces its manufacturing cost.

In addition, a device according to the present invention comprises a bead wire having a plurality of bead securing elements defined along said bead wire; a control finger comprising at least one control finger securing element; and at least one bolt comprising at least one bolt securing element.

It is thus advantageously possible to provide several bolts each cooperating with a rod fastening element, or to provide a single bolt. In this case, if the number of bolts is less than the number of rod fastening elements adapted to cooperate with a bolt, one can choose the position of the bolt or bolts along the rod according to the position of the corresponding strike . The bead wire may be formed by a section of rod cut in a long rod without substantial material loss since the presence of several bead fastening elements adapted to cooperate with a bolt will easily place one of them in the desired position with respect to the waste.

One can also thus, optionally, provide a control finger having a plurality of control finger securing elements each cooperating with a rod fastening element, or provide a control finger having a single finger locking member. ordered. If the number of control finger fastening elements is less than the number of rod fastening elements adapted to cooperate with a control finger fastening element, the position of the control finger can be chosen along the rod. depending on the position of the primary actuator.

Advantageously, according to a first aspect of the invention, the rod has a control finger slot whose edge forms said one of said rod securing elements, and the control finger securing element comprises a finger retaining tab. control, adapted to be retained by the edge of said control finger slot.

It is thus understood that the fastening of the control finger with the rod is effected by cooperation of the edge of the control finger slot with the control finger retaining tab.

Advantageously, said control finger retaining tab is substantially contained in a plane PO and said control finger slot has an elongation direction inclined with respect to said plane PO, when the control finger is integral with the rod, so that the fastening of the control finger with the rod is effected by engagement and rotation of the control finger retaining tab, which allows to easily secure or separate the control finger with the rod.

Advantageously, said control finger slot has an elongation direction inclined with respect to the longitudinal direction, and said plane PO is substantially parallel to the longitudinal direction, when the control finger is integral with the rod.

According to an advantageous alternative, said control finger slot has an elongation direction parallel to the longitudinal direction, and said plane PO is substantially inclined with respect to the longitudinal direction, when the control finger is secured to the rod.

According to an advantageous alternative to the first aspect of the invention, the rod has a clipping recess for a control finger, the edge of which forms said one of said rod securing elements, and the control finger securing element comprises a tab of clipping control finger, adapted to cooperate with the edge of the clipping recess for control finger.

Advantageously, according to a second aspect of the invention, the bead wire has a slot for a bolt whose edge forms said other of said bead fastening elements, and the bolt fastening element comprises a bolt retention lug, suitable for being retained by the edge of said slot for bolt.

It is thus understood that the fastening of the bolt with the rod is effected by cooperation of the edge of the slot for bolt with the latch retaining tab.

Advantageously, said bolt retaining tab is substantially contained in a plane PI and said bolt slot has an elongation direction inclined with respect to said plane PI, when the bolt is secured to the rod, so that the locking of the bolt with the rod is made by engagement and rotation of the bolt retaining lug, which allows to easily secure or disengage the bolt with the rod.

Advantageously, said slot for bolt has an elongation direction inclined with respect to the longitudinal direction, and said plane PI is substantially parallel to the longitudinal direction, when the bolt is secured to the rod.

According to an advantageous alternative, said slot for bolt has an elongation direction parallel to the longitudinal direction, and said plane PI is substantially inclined with respect to the longitudinal direction of the rod, when the bolt is secured to the rod.

According to an advantageous alternative to the second aspect of the invention, the bead wire has a clipping recess for a bolt whose edge forms said other of said bead fastening elements, and the bolt fastening element comprises a bolt clipping lug, adapted to cooperate with the edge of the clipping recess for bolt.

Advantageously, said rod fastening elements are similar or identical to each other.

It is thus understood that any rod fastening element is able to cooperate with both a control finger securing element and a bolt securing element, which further increases the modularity of the device.

Advantageously, the control finger securing element is similar, preferably identical, to the bolt securing element.

Advantageously, according to a third aspect of the invention, the primary actuator comprises a lever adapted to be pivotally mounted on the leaf about a pivot axis.

Advantageously, the pivot axis of the lever is substantially parallel to the plane of the leaf and substantially perpendicular to said longitudinal direction of the rod, so that the application of a simple traction force on the lever allows both to maneuver the lever and move the leaf, which facilitates the opening of the leaf.

According to an advantageous alternative to the third aspect of the invention, the primary actuator comprises a slider adapted to be slidably mounted substantially in the longitudinal direction on the leaf.

It is thus understood that a displacement of the slider in the first direction of movement makes it possible to urge the control finger to control the rod in translation.

Advantageously, the device comprises at least one return element adapted to be secured to the leaf to urge the rod in a direction of displacement opposite to said first direction of movement.

It is thus understood that the rod, after being moved to the unlocking position, can more easily return to the locking position due to the biasing of the biasing element.

The return element may advantageously be fixed, optionally, either directly on the leaf, or on any intermediate piece which is distinct from the leaf and which is attached thereto, provided only that in the end the return element is secured. at the door.

Thus, for example, the return element may advantageously be integral with a guide block, adapted to be mounted on the leaf so as to be traversed by the bolt, which facilitates the assembly and disassembly of the return element on the leaf while allowing the bolt to be better guided in translation during a movement of the rod.

Advantageously, the biasing element urges the rod by cooperation with one end of said rod.

Advantageously, the bolt has a ramp adapted to cooperate with said striker during a closing movement of the leaf and until the leaf reaches its closed position, so that the rod moves in translation according to the first direction of movement until the bolt can cooperate with the strike to lock the leaf in its closed position.

It is thus understood that when the leaf is in the open position and that it is desired to close it and lock it in the closed position, it is not necessary to operate the primary actuator to control the rod in translation; it suffices to apply a pulse on the leaf so that the latter closes and locks itself in the closed position by inertia. This results in an improvement of the ergonomics of the device.

In this case, the bolt may advantageously also have a recess provided between said ramp and said latch bolt member to cooperate with the latch to lock the leaf in the closed position.

It will be understood that the closing position of the leaf, which is reached once the closure movement of the leaf is complete and in which the ramp no longer co-operates with the striker, is thus determined by the position of the leaf in which the recess of the bolt can cooperate with the waste.

Advantageously, the device comprises an unlocking mechanism of the leaf when the latter is in the closed position, comprising a secondary actuator adapted to be operated on the side of the leaf opposite the side from which said primary actuator is maneuvered; and a movable unlocking member adapted to be moved by the secondary actuator so as to bias the bolt in the first direction of movement.

It is understood that it is thus possible to control the rod in translation in the first direction of movement from the opposite side to the side from which the primary actuator is maneuvered, which allows to control the unlocking of the leaf whatever the side facing which is when the leaf is in the closed position.

Advantageously, the control finger is integral with a plate on which is formed said control finger fastening element.

It is understood that it is thus possible to form a plurality of control finger fastening elements on the plate, so that the fastening of the control finger with the rod is made at several points.

Preferably, the control finger and the plate are formed in one piece, which simplifies the device.

Alternatively, the control finger is distinct from the plate and is adapted to be secured to the latter.

Advantageously, the device comprises means for securing said locking position of the rod.

It is understood that it is thus possible to secure the locking of the leaf in the closed position, even when the rod is biased in translation, which makes it possible to prevent an opening of the leaf by breaking-in or by a child for example.

Advantageously, said securing means comprise a stop wall secured to the rod and a movable securing element having a projecting portion adapted to cooperate with the stop wall to secure said locking position of the rod.

It is thus understood that the cooperation of the stop wall with the projecting part of the movable securing element makes it possible to secure the rod in the locked position.

Advantageously, a housing whose periphery forms said stop wall is directly formed in the rod and the movable securing element comprises a pin forming said projecting portion, whereby said tenon is able to engage in said housing to secure the locking position of the rod.

According to an advantageous alternative, when the control finger is secured to a plate adapted to be secured to the rod, a housing whose periphery forms said stop wall is formed in the plate and the movable securing element comprises a tenon forming said projecting portion, whereby said tenon is able to engage in said housing to secure the locking position of the rod.

According to another advantageous alternative, when the control finger is secured to a plate adapted to be secured to the rod, the stop wall is in the form of a stop face projecting from the plate, and the movable securing element comprises a projecting face forming the projecting portion adapted to bear against the stop face to secure the locking position of the rod.

A lock control device for opening leaf 1 of frames according to the present invention comprises a primary actuator 2 adapted to be mounted operatively on the leaf 1 and a locking subassembly 3 adapted to be slidably mounted on the leaf 1.

In Figure 1, there is shown a perspective view of the locking subassembly 3. The locking subassembly 3 comprises a rod 10; two bolts 30 integral with the rod 10; and a control finger 20 secured to the rod 10.

The rod 10 is in the form of a rod which extends in a longitudinal direction Z and whose section is rectangular, so that the rod 10 has a first main face 11 and a second main face 12 opposite longitudinal l ' one to another.

The bead wire 10 comprises several bead fastening elements defined along said bead wire 10.

In the illustrated embodiment, the rod 10 has a plurality of slots 16 substantially regularly spaced along said rod 10. The edge of each of these slots forms a rod fastening element.

Advantageously, each of these slots 16 has an elongation direction D inclined with respect to the longitudinal direction Z of the rod 10.

Advantageously, the slots 16 are identical to each other.

With regard to the control finger 20, it is configured to be solicited by a maneuver of the primary actuator 2 when the locking control device is mounted on the leaf 1, so that a maneuver of the actuator primary 2 control in translation the rod 10 in the longitudinal direction Z, as will be detailed a little further.

According to the example illustrated in FIG. 2A, the control finger 20 is substantially plane and has a useful part 24 which extends into a control finger fastening element substantially contained in a plane PO.

The control finger securing element is adapted to cooperate with a rod fastening element for securing the control finger 20 with the rod 10.

In the illustrated embodiment, the control finger securing member is in the form of a control finger retaining tab 22.

Advantageously, the control finger retaining tab 22 has a shape substantially "T", so that the retaining tab 22 has a proximal segment 22A ensuring the junction between the retaining tab 22 and the useful part 24 of the finger 20 and a distal segment 22B substantially perpendicular to the proximal segment 22A so as to define two retaining surfaces.

As illustrated in FIGS. 2A to 2C, the fastening of the control finger 20 to the bead wire 10 takes place by presenting the control finger 20 in front of a slot 16 of the bead wire 10 so that the extension direction D of the bead 10 slot 16 is substantially contained in the plane PO; and then engaging the retaining tab 22 in the slot 16 until the two retaining surfaces emerge from the slot 16 on the side opposite the side from which the control finger 20 is engaged in the slot 16; and finally by rotating the control finger 20 so that the plane PO is substantially parallel to the longitudinal direction Z of the rod 10, which allows the two retaining surfaces to be retained by the edge of the slot 16 so as to secure the control finger 20 with the rod 10. As a result, the useful part 24 of the control finger 20 protrudes from the first main face 11 of the rod 10.

According to the example illustrated in FIG. 3A, a substantially planar bolt 30 has a useful portion 34 which extends into a bolt securing element substantially contained in a plane referenced PI.

The bolt securing element is adapted to cooperate with a bead securing element for securing the bolt 30 with the bead wire 10.

In the illustrated embodiment, the bolt securing element is in the form of a bolt retainer 32.

Advantageously, the latch retaining clip 32 has a substantially "T" shape similar to that of the control finger retaining tab 22, so that the retaining tab 34 of bolt is adapted to be retained by the edge a slot 16 to allow the locking of the bolt 30 with the rod 10.

Advantageously, as illustrated in FIGS. 3A to 3D, the locking subassembly 3 further comprises a guide block 40 able to guide the rod 10 in translation in the longitudinal direction Z. The guide block 40 has a face for this purpose. planar 41 from which preferably projecting head-to-tail two guide portions each comprising a guide lug 45, 47 substantially elastic in front of which stands a guide portion 44, 46 substantially rigid.

Advantageously, the guide block 40 has an opening 42 opening into the flat face 41 configured to be traversed by a bolt 30 so as to guide the latter in translation when the rod moves in the longitudinal direction Z.

As illustrated in FIGS. 3A to 3D, the securing of a bolt 30 with the rod 10 is carried out by introducing the bolt 30 into the opening 42 of the guide block 40; then presenting the assembly consisting of the guide block 40 and the bolt 30 in front of a slot 16 so that the elongation direction D of the slot 16 is substantially contained in the plane PI and that the plane face 41 of the guide block 40 is facing the second main face 12 of the rod 10; then engaging the retaining tab 32 in the slot 16 until the two retaining surfaces emerge from the slot 16 of the rod 10 on the side opposite the side from which the bolt 30 is engaged in the slot 16; and finally by rotating the assembly constituted by the guide block 40 and the bolt 30 so that the plane PI is found substantially parallel to the longitudinal direction Z of the rod 10, which allows the two surfaces retainer to be retained by the edge of the slot 16 so as to secure the bolt 30 with the rod 10. As a result, the useful part 34 of the bolt 30 protrudes from the second main face 12 of the rod 10, and that the rod 10 is slidably mounted in the two guide portions of the guide block 40 against the flat face 41.

Advantageously, a return element is provided integral with the guide block 40 so as to urge the rod in translation relative to the guide block 40 in the longitudinal direction Z by cooperation with the bolt 30.

According to the example illustrated in FIGS. 3A to 3D, the return element is in the form of a leaf spring 48 comprising a first end formed preferably in one piece with the guide block 40 and a second end free having a notch 49 adapted to cooperate with the useful part 34 of the bolt 30.

In FIG. 4A, there is shown a leaf 1 plane on which the locking subassembly 3 is mounted.

As illustrated in FIG. 5C, the leaf 1 has a larger dimension H and a smaller dimension L, and is itself mounted in a frame 7 for a single opening.

In the example illustrated, the mounting of the locking subassembly 3 on the leaf 1 is performed by presenting the second main face 12 of the rod 10 facing the leaf 1, so that the longitudinal direction of the rod Z is parallel to the largest dimension H of the leaf 1; then inserting the guide blocks 40 provided with the bolts 30 inside notches 5 formed on the leaf 1; and finally by securing the guide blocks 40 to the leaf 1 by screw engagement 43 in holes formed on the guide blocks 40, so that the screw head 43 bears on the edge of the notches 5 on the opposite side at the side from which the guide blocks 40 are introduced into the notches 5, preferably by means of washers 45.

It is thus understood that once the locking subassembly 3 mounted on the leaf 1, the rod 10 is able to slide in the longitudinal direction Z on the leaf 1, the rod 10 being in the example shown slidably mounted on the guide blocks 40 which are secured to the leaf 1.

Advantageously, as shown in Figure 4D, a battue 60 is secured to the leaf 1 so as to cover the rod 10, which is more aesthetically pleasing.

In order not to hinder the translation of the rod 10, the beater 60 has an opening 62 configured to remotely surround the control finger 20 when the battue 60 is secured to the leaf 1, so that the control finger 20 can translate in the longitudinal direction Z without the beat 60 does not hinder its movement.

We will now describe the primary actuator 2 which constitutes another element of the locking control device according to the invention.

According to the present invention, the primary actuator 2 is able to be mounted operatively on the leaf 1 so as to translate the rod 10 in translation in a first direction of movement along the longitudinal direction Z shown in FIGS. 5A and 5B by the reference O.

Advantageously, the primary actuator 2 comprises a lever 70 adapted to be pivotally mounted about an axis 72 on the leaf 1.

In the illustrated example, the axis of the lever 72 is housed in a lever support 74 intended to be secured to the leaf 1 so that the axis of the lever 72 is substantially parallel to the plane of the leaf 1 and substantially perpendicular in the longitudinal direction Z, which allows the lever 70 to pivot in a plane substantially parallel to the longitudinal direction Z and substantially perpendicular to the plane of the leaf 1 when the primary actuator 2 is maneuvered.

Advantageously, a handle 76 is provided in the extension of the lever 70, these two elements being formed in one piece. Thus, the operation of the lever 70 can be performed through the handle 76, which increases the ergonomics of the lock control device.

According to the example illustrated in FIG. 6A, latches 80 are secured in the rabbet of a jamb of the frame 7, so that each of the latches 80 can cooperate with an associated bolt 30 when leaf 1 is in a closed position.

In the example shown, a striker 80 has a stud 82 projecting from the rabbet of the amount of the frame 7.

According to the illustrated example, a bolt 30 has not only a ramp 39 but also a recess 38.

Advantageously, the recess 38 of the bolt 30 is provided in the useful part 34 of said bolt, between the bolt retaining lug 32 and the end of the useful part 34 opposite the end from which the bolt 30 extends into the lug. bolt retainer 32.

It is thus understood that when the leaf 1 is in the closed position, the recess 38 can cooperate with the pin 82 of a keeper 80 to lock the leaf 1 in the closed position.

Advantageously, the securing position of the striker 80 with the leaf 1 can be adjusted in the plane of the rabbet of the frame 7 by means of a relative position adjustment system, in particular the system 84 comprising screws mounted in oblong holes shown in Figures 6B and 6C. It will be understood that the presence of such an adjustment system 84 makes it possible to precisely adjust the position of the striker 80 on the frame 7 so that the recess 38 of a bolt 30 can cooperate even more effectively with the stud. 82 a strike 80 when the leaf 1 is in the closed position.

Advantageously, the ramp 39 of the bolt 30 is formed in the end of the useful part 34 opposite the end from which the bolt 30 extends into the bolt retaining lug 32, so that the recess 38 is between the ramp 39 and bolt retainer 32.

The ramp 39 is configured so as to cooperate with the pin 82 of the striker 80 during a closing movement of the leaf 1 and until the leaf 1 reaches its closed position, so that the rod 10 moves in translation in the first direction of movement O until the recess 38 can cooperate with the pin 82 of the striker 80 to lock the leaf 1 in its closed position.

The opening kinematics of leaf 1 will now be described. When the leaf 1 is in the closed position, the rod 10 is in a locking position in which the recess 38 of the bolts 30 cooperates with the pin 82 of a corresponding strike 80 to maintain the leaf 1 in the closed position, as shown in Figure 6B. Maneuvering the lever 70 via the handle 76 causes a biasing of the useful part 24 of the control finger 20 of the rod 10, which allows to control in translation the rod 10 in the first direction of movement O and so to move the rod 10 in an unlocked position, as shown in Figure 6C. The leaf 1 can then be opened by pulling the handle 76. When the leaf 1 is open and the handle 76 is released, the rod 10 is biased in a direction of movement opposite to the first direction of movement O, on the one hand under the effect of its weight, on the other hand under the effect of leaf springs 48 which cooperate with a bolt 30 associated. As a result, the rod 10 returns to the locking position.

The closing kinematics of leaf 1 will now be described. We have just seen that when the leaf 1 is in the open position, the rod 10 is finally in the locking position. To close the leaf 1, it is then not necessary to maneuver again the handle 76. It suffices to apply a simple pulse on the leaf 1 so that the latter moves to the closed position. The inertia generated during this movement allows the ramp 39 of the bolts 30 to cooperate with the pin 82 of a corresponding strike 80, so that the rod 10 moves in translation in the first direction of movement O, which allows the rod 10 to come into the unlocking position. Once the leaf 1 in the closed position, the rod 10 returns to the locking position under the effect of its weight and leaf springs 48, so that the recess 38 of a bolt 30 cooperates with the pin 82 a corresponding strike 80 to hold the leaf 1 in the closed position.

The lock control device according to the present invention may include additional functions.

Thus, the device may advantageously comprise a mechanism for unlocking leaf 1 when the latter is in the closed position.

According to the example illustrated in Figures 7A and 7B, such an unlocking mechanism 90 may in particular comprise a secondary actuator 92 adapted to be operated on the side of the leaf 1 opposite the side from which the primary actuator 2 is operated; and a movable unlocking member 94 adapted to be moved by the secondary actuator 92 so as to bias a bolt in the first direction of movement O of the rod.

Advantageously, the secondary actuator 92 is in the form of a slider that can be slidably mounted on the rabbet of the jamb of the frame 7 on which the latches 80 are secured.

Advantageously, the secondary actuator 92 and the movable unlocking element 94 are two distinct elements.

In the illustrated example, the movable unlocking element 94 is in the form of a lever that can be pivotally mounted on the rabbet of the jamb of the frame 7 on which the strikers 80 are secured, and having a first end adapted to cooperate with a housing formed in a projection that has the slide 92 and a second end adapted to cooperate with the bolt 30 when the leaf 1 is in the closed position. It is thus understood that a maneuver of the slider 92 causes a biasing of the lever 94 pivotally so that said lever 94 is set in motion and in turn urges the bolt in the first direction of movement O, so that the rod 10 can be controlled in translation to unlock the closing position of leaf 1.

The lock control device according to the present invention may also advantageously comprise a plate secured to the control finger and adapted to be secured to the rod.

According to the example illustrated in FIG. 10A, the control finger 124 and the plate 120 are formed in one piece.

The plate 120 has two retaining tabs 122.

The plate 120 and the retaining tabs 122 are formed in one piece.

The retaining tabs 122 are each adapted to cooperate with the edge of a slot 16 to secure the control finger 124 with the rod 10 via the plate 120.

The locking control device according to the present invention may also advantageously comprise means for securing the locking position of the rod 10.

Preferably, the securing means comprise a stop wall integral with the rod 10, and a movable securing element having a projecting portion adapted to cooperate with the stop wall to secure said locking position of the rod.

According to the example illustrated in FIGS. 10A to 10C, the presence of a plate 120 can advantageously be used to form a housing 126 on the plate 120 whose periphery forms the stop wall. The periphery of the housing 126 is configured to cooperate with a projecting portion of a key cylinder 110 in the form of a pin 112, the key cylinder 110 being configured to be mounted in a support 174 of the primary actuator 170 so as to be secured to the leaf 1.

Furthermore, it is important to note that the embodiments which have been previously illustrated are given by way of non-limiting examples. As a result, a lock control device according to the present invention can be realized according to other embodiments.

In particular, a bead wire 10 according to the present invention does not necessarily have a rectangular section, so that it would be possible to provide, without departing from the scope of the present invention, a rod having a section of a completely different shape, in particular square or having one or more arc of circles, provided that the rod is able to be slidably mounted on the leaf 1.

In addition, it has been previously described rod fastening elements formed by the edge of identical slots, so that it could be provided, without departing from the scope of the present invention, non-similar bead fastening elements between they, for example rod securing elements formed by the edge of slots not analogous to each other, provided that at least one rod securing element is adapted to cooperate with a control finger securing element, and provided that at least one rod fastening element is adapted to cooperate with a bolt fastening element.

In addition, it has previously been described a control finger securing element in the form of a control finger retaining tab and a bolt securing element in the form of a retaining tab. bolt similar to the control finger retaining tab, so that one could provide, without departing from the scope of the present invention, a control finger fastening element not analogous to a bolt fastening element, provided a control finger securing element is adapted to cooperate with at least one rod securing element, and provided that a bolt securing element is adapted to cooperate with at least one rod securing element.

Furthermore, it has previously been described a locking control device comprising two bolts which are each adapted to cooperate with a striker, so that one could provide, without departing from the scope of the present invention, a control device locking device comprising another number of bolts, provided that this number is at least equal to one.
