Description

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

It relates more specifically to a locking control device for a leaf opening frame, 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.

[0003] 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 leaf plane 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 through 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 end locking is adapted to cooperate with the hole of the striker 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 adapted to the dimension of the leaf in the longitudinal direction of the rod, the locking end of the rod to exceed one edge of the transverse leaf in the longitudinal direction so as to cooperate with the hole of the keeper 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 a first aspect of the present invention is characterized in that the rod comprises a plurality of rod fastening elements defined along said rod, in that that the control in translation of the rod is effected by means of 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 rod by cooperation with one of said rod securing elements, in that said bolt comprises at least one bolt securing element adapted to secure the bolt with the rod in cooperation with another of said elements for securing a rod, and in that the primary actuator comprises a lever that can be pivotally mounted about a pivot pin otement substantially perpendicular to the longitudinal direction of the rod and in the mounted state of the device on the leaf, substantially parallel to the plane of the leaf.

With 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 rod having a plurality of rod fastening elements defined along said rod; a control finger comprising at least one control finger securing element; and at least one bolt comprising at least one bolt securing element.

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.

It is also possible, as desired, to provide a control finger having a plurality of control finger fastening elements cooperating, each with a rod fastening element, or provide a control finger having a single fastening element of control finger. 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.

It is thus understood that any rod fastening element is adapted 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 the invention, 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 makes it possible to both maneuver the lever and move the leaf, which facilitates the opening of the leaf.

Advantageously, the device comprises at least one return element adapted to be secured to the leaf for biasing the rod in a direction of movement 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 can advantageously be fixed, optionally, either directly on the leaf, or on any intermediate piece which is separate from the leaf and which is reported on the latter, provided only that in the end the element of reminder is secured to the leaf.

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

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

Alternatively, the control finger is separate 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 prevents the opening of the leaf by breaking or by a child for example.

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

In FIG. 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 longitudinal opposite to each other.

The rod 10 has a plurality of rod fastening elements defined along said rod 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 bead securing element.

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

Advantageously, the slots 16 are identical to each other.

Regarding the control finger 20, it is configured to be biased 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 primary actuator 2 controls 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 portion 24 which extends into a control finger fastening element substantially contained in a plane referenced P0.

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 element 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 control 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 with the rod 10 is effected by presenting the control finger 20 in front of a slot 16 of the rod 10 so that the elongation direction D of the slot 16 is substantially contained in the plane P0; 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 P0 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 P1.

The locking member of the bolt is adapted to cooperate with a rod fastening element for securing the bolt 30 with the rod 10.

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

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

[0070] 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. In this case, the guide block 40 has a flat face 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 fastening 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 P1 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 P1 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 member is in the form of a leaf spring 48 comprising a first end preferably formed integrally with the guide block 40 and a second free end 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 is mounted the locking subassembly 3.

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 single opening.

In the illustrated example, 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 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 slidable in the longitudinal direction Z on the leaf 1, the rod 10 being in the illustrated example mounted sliding on the guide blocks 40 which are secured to the leaf 1.

[0079] Advantageously, as illustrated in FIG. 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 control in translation of the rod 10, the battue 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 finger control 20 can translate in the longitudinal direction Z without the battue 60 comes hinder its movement.

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

According to the present invention, the primary actuator 2 is adapted to be mounted operable on the leaf 1 so as to control in translation the rod 10 in a first direction of movement in 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 example shown, 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 to 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.

[0085] 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 an amount of the frame 7, so that each latch 80 can cooperate with an associated bolt 30 when the 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.

In the example shown, 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 latch retaining tab 32 and the end of the useful part 34 opposite the end from which the bolt 30 extends. in the 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 illustrated in FIGS. 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 to the end from which the bolt 30 is extended in the bolt retainer 32, so that the recess 38 is located between the ramp 39 and the 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 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 fig. 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 to an unlocked position, as shown in FIG. 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 FIGS. 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 to the side from which the primary actuator 2 is maneuvered; 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 able to be slidably mounted on the rabbet of the amount 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 mobile unlocking element 94 is in the form of a lever adapted to be pivotally mounted on the rabbet of the amount of the frame 7 on which are secured the latches 80, 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 comprises 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 lock 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 secured to 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 may advantageously be used to form a housing 126 on the plate 120 whose perimeter 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.
