Description

The present invention relates to a locking mechanism control method and device, in particular for door, window and the like. More particularly, the invention relates to a method for controlling the unlocking of a locking fitting such as a cremone or espagnolette lock using a control device comprising a handle, movable between a locking position and at least one an unlocked position, said handle actuating drive means able to act on at least one locking member, such as an operating rod, for starting from a first so-called locking position of these drive means, to bring them in at least a first and a second unlocked position. The present invention also relates to a control device for carrying out this method. The present invention will find its application in the field of locking devices carpentry type lock, espagnolette or espagnolette-lock; more generally it concerns the field of building hardware. Locking brackets are already known, which make it possible both to lock and unlock a door or window but also to allow two modes of opening the door or window. Thus, it is quite common that such a locking device allows, from a locked position, to reach a first unlocked position to allow the opening of a window, for example, by rotating a leaf around of a vertical pivot axis, then, that brought into a second unlocked position, this locking device allows the opening of such a leaf by flipping, that is to say by rotation about an axis horizontal corresponding substantially to the lower cross of this leaf. Obviously, adapted means limit the tilting of this leaf. Such a position is often referred to as aeration. If these different opening modes can be reversed in the unlocking control order, the two unlocked two positions of the driving mechanism of such a locking device are successively achieved successively, starting from an extreme locking position. . It is usually a control handle that actuates this rotational drive mechanism, and thereby the two unlocked positions, from the lock position are reached. In sum, the user submits the handle to a first rotation of about 90 ° to move from the locking position in said first unlocked position while a second rotation of similar amplitude, in total 180 °, allows to pass in the second unlocking position. This configuration has become a rule in this area primarily for aesthetic considerations. In particular, whether it is an installation on a horizontal cross member of a carpentry or on a vertical upright, unlocking position this control handle can be brought into a position as appropriate, horizontal parallel to said cross or vertical parallel to the amount of the joinery so as not to extend into the clear glazing and obscure, in part, the latter. Knowing that it is very often the second unlocking position which corresponds to the ventilation opening of the joinery, the control handle does not extend before this clear glazing in full open position. Finally, current solutions have been adopted to the detriment of more technical considerations and ease of handling of this type of locking device. In particular, it has been found that a window or French window is much more often closed or, when it is open, brought into a ventilation position, than in a fully open position. In short, when one comes to manipulate the locking devices, it is more frequently to bring the control handle from its locking position 35 in the second unlocking position called aeration. However, for many people, especially with reduced mobility, -3 this second unlocking position corresponding to a rotation most frequently of the order of 180 °, it is necessary to perform a double manipulation for, in a first mode of grasp, ensure a first 90 ° rotation of the handle and, in a second mode of gripping, continue the rotation and reach 180 °, otherwise this position can not be reached without subjecting the wrist and forearm to a constraining rotation for such users. It is within the framework of an inventive step that it has been imagined that these different possibilities of opening a door or window can be obtained by the same movement applied to the handle by the user this through means adapted selectors. In particular, it has been imagined that these selector means can be controlled very easily and without necessarily resulting in a displacement of the mechanism of the locking fitting. In short, it has been thought that the selector means can be summed up in a single button or equivalent whose movement can be obtained with the aid of a single finger and therefore without the efforts of the user.

For this purpose, the present invention first relates to a method for controlling the unlocking of a locking fitting with the aid of a control device comprising a handle movable between a locking position and at least one unlocked position. said handle actuating driving means able to act on a locking member, such as an operating rod, for starting from a first so-called locking position of these driving means, to bring them into at least a first and a second unlocked position characterized in that it comprises the following steps: - is selected, through a control switch, an opening mode corresponding to one or the other unlocked position of the drive means; starting from a locking position, the handle is raised by giving it a displacement in a direction and according to a defined amplitude to bring the means at least 4 drive in one or the other unlocked position according to the position the control selector. Advantageously, after an unlocking command on the handle, the action is released on the handle and, thanks to a vacuum stroke with respect to said drive means, said handle is returned to its initial locking position, for example under the pulse of elastic return means. According to another particularity of the invention, it ensures the maintenance of the drive means, in one and / or the other unlocked position against the action of elastic return means, and the return of the means of control is controlled. drive in their locking position by releasing the action of the elastic return means.

The present invention also relates to a control device for locking fitting, in particular a cremone or espagnolette lock, comprising a handle movable between a locking position and at least one unlocked position, said handle actuating driving means able to act on to less a locking member, such as an operating rod, for starting from a first so-called locking position of these drive means, to bring them into at least a first and a second unlocked position characterized in that it comprises a control selector for, starting from a first so-called locking position of these drive means, to bring them into at least the first and second unlocked position, under the impulse of a displacement of the same direction and travel substantially identical to the handle.

Interestingly, races in opposite directions of said drive means allow to reach, from the locking position, the first position and the second unlocked position of said drive means. According to another exemplary embodiment, strokes of different amplitude in the same direction of said drive means make it possible to reach, from the locking position, the first position and the second unlocked position of said drive means. . Preferably, the control device comprises mounting means applied to a support, in particular a door or window opening, the handle being pivotally mounted between the locking position and the unlocked position about an axis parallel to said support. .

The present invention relates to a method for unlocking and locking a locking fitting, in particular a cremone or espagnolette lock, for opening and closing control of a door, window or the like, this with the aid of a control device 1 according to the invention. This control device 1, illustrated in various embodiments in FIGS. 1 to 21 of the accompanying drawings, comprises a handle 2, movable between a locking position 3 and at least one unlocked position 4. This handle 2 actuates driving means 5 adapted to act on at least one locking member, such as an operating rod. This action of the handle 2 is intended, starting from a so-called locking position 6 of these drive means 5, to bring the latter into at least a first unlocked position 7 and a second unlocked position 8. Usually, these two unlatched distinct positions 15 generally correspond to two modes of opening the door or window, for example an opening by rotation around a vertical axis and an opening by rotation about a horizontal axis known as "sloping". . More generally, one of these modes corresponds to a total opening of the joinery while the other is, often, a position known as "aeration". The particularity of the method according to the invention consists, in an initial situation of closing a joinery, in selecting, through a control selector 9, an opening mode corresponding to one or the other position unlocked 7, 8 of the drive means 5 and, starting from the locking position 3 of the handle 2, to raise the latter, conferring on it a displacement in a direction D and a defined amplitude A to bring the means 30 5 in one or the other unlocked position 7, 8, depending on the position of the control selector 9. In short, whatever the unlocked position 7, 8 sought, and, therefore, the opening mode of the carpentry, total opening or ventilation, the user transmits to the handle 35 2 always the same movement, except that with the help of a control selector 9, this displacement acts differently on -9 the driving means 5 to obtain the opening mode s ouhaité. Consequently, one of the opening modes is not the result of a complementary stroke transmitted to the handle 2 relative to that communicated to the latter to obtain the other opening mode. Referring now more particularly to Figures 1 to 5 corresponding to a first embodiment of the control device 1 according to the invention. The handle 2 of this control device 1 is in the form of a lever rotatably mounted on a base 10 may be reported, especially applied to the inner side of a door leaf or window. Thus, the handle 2, or the lever, is mounted (e) in rotation about an axis 11 substantially parallel to the plane of the base 10.

As for the drive means 5, they consist of a toothed sector 12 engaged with the rack 13 of a first bridge 14 slidably mounted on the base 10 advantageously forming housing. The toothed sector 12 is in the shape of an arc around the axis of rotation 11 of the handle 2 so that, starting from the locking position 3 of the latter, visible in FIG. 1, to reach the unlocked position 4 visible in Figures 2 and 3, this toothed sector 12 pushes, in a direction dl, the first bridge 14. It is still engaged by means of displacement amplification means 15, with a second bridge 16, also slidably mounted on the base 10 and consequently move in the same direction dl but in a stroke C2 greater than the stroke Cl communicated to the first bridge 14 by the handle 2. As for the control selector 9, it is present in the form of a latch 17 movable between a first position Pl in which the latch 17 is engaged with the first bridge 14 and a second position P2 in which the latch 17 is engaged with the second bridge 16. In addition, audit rag 17 is associated with a transmission member 18 which can be brought into engagement with the locking member to be controlled, for example an operating rod. It is understood, therefore, that it will be transmitted to this locking member, a race according to the case C1 or C2. The transmission member 18 is shown in the drawings as a driving fork. As for the displacement amplification means 15, these can be, in an exemplary embodiment, in the form of a toothed wheel 20 fixedly mounted in displacement on the first bridge 14 while being free to rotate by relative to the latter, this toothed wheel 20 being diametrically opposed engaged on the one hand, on a fixed rack 21, for example defined in the base 10 and a second rack 22 that includes the second bridge 16, the amplification of the displacement depending on the transmission ratio obtained through the gear 20. Referring now more particularly to Figures 6 to 10 corresponding to a second embodiment of the control device 1 according to the invention. It should be observed that the components of the control device 1 according to this second embodiment, identical to those of the device 1 of the first embodiment, have the same references. In particular, the handle 2, by rotation about its pivot axis 11 on the base 10, acts through a toothed sector 12 on a rack 13 of a first bridge 14 subjecting the latter to a movement in a first direction dl, according to a defined race Cl. According to this second embodiment, this first bridge 14 is engaged, through an inverter 23 with the second bridge 30. Also, under the action of the handle 2 it is subject to the latter a movement in one direction d2 opposed to the management dl. The control selector 9 may take a form of execution identical to that described with regard to the first embodiment. Thus, according to the position P1 or P2 of the latch 17, the latch 17 is pushed by the first bridge 14 or the second 16 and transmits via its transmission member 18 a stroke Cl in a direction dl to the organ of locking, in particular an operating rod, or a stroke C2 in an opposite direction d2.

Substantially the inverter 23 may be in the form of a toothed wheel rotatably mounted on the base 10 and in engagement, diametrically opposed with a rack 21a of the first bridge 14 and a rack 22a of the second bridge 16.

Note also that through not one but two coaxial gear wheels, integral in rotation, and of different nominal diameter, the transmission ratio between the first bridge 14 and the second bridge 16 can be adjusted. The embodiment corresponding to FIGS. 6 to 8 illustrates the possible application of the control device 1 for a cremone or espagnolette-lock type locking fitting comprising two operating rods with opposite or identical displacement. The principle is as follows: in a first position Pl of the control selector 9, therefore the latch 17, it is engaged with the first bridge 14. At the same time, the latter cooperates with an operating rod through a transmission member 18a and the latch 17 acts with its own transmission member 18 with another operating rod, so that said operating rods move concomitantly. In the second position P2 of the control selector 9, the latch 17 is engaged on the second bridge 16, causing a displacement in the opposite direction of said operating rods 30 during the unlocking control of the handle 2. We are now reporting more particularly in Figures 11 to 16 corresponding to a third embodiment of the control device 1 according to the invention. It should be observed that the components of the control device 1 according to this third embodiment, identical to those of the device 1 of the first and second embodiments, have the same references. Thus, as can be seen in these figures, the handle 2, again in the form of a lever, is rotatably mounted about the pivot axis 11 passing through the housing formed by the base 10. As for the means of 5, they comprise here, substantially, a transmission fork 24 rotatably mounted on the same pivot axis 11 as the handle 2 on one side 32 thereof. This transmission fork 24 plays the same role as the transmission member 18 associated with the latch 17 of the control selector 9 in the two embodiments described above. In particular, this transmission fork 24 can be engaged on a drive pad 15 associated with a locking member such as an operating rod. Furthermore, beyond the pivot axis 11 this transmission fork 24 comprises a drive tab 25 on which is able to act the handle 2 by means of a drive finger 26 for by pushing said handle 2 from its locking position 3 into its unlocked position 4, rotating the transmission fork 24 in a first direction d1. Said drive means 5 further comprise a slider 27 mounted on the opposite side 33 of the handle 2 with respect to the transmission fork 24. This slider 27 is engaged with a driving pin 28 that includes the transmission fork 24 under the axis 11, or diametrically opposed to the drive tongue 25 relative to this axis 11. Advantageously, this slider 27 is guided in displacement by the base 10 forming a housing and / or by the pivot axis 11 Ledit slider 27 in turn comprises a drive tongue 25a again adapted to cooperate with a drive finger 26a of the handle 2 to, by action on the latter, and from its locking position 3 to reach the unlocked position 4, push the slider 27 from a first position 29 to a second position 30. Due to the cooperation of this slider 27 with the driving pin 28 under the pivot axis 11, it results a rotation of the transmission fork 24 in a direction d2 opposite to the direction of rotation dl.

As for the control selector 9 it is defined in the form of a latch 17 traversing transversely the handle 2 is parallel to the axis 11. This latch 17 under the impulse of a pusher 31 may alternatively be pushed out protrudingly. one side 32 of the handle 2 forming the drive finger 26 adapted to cooperate with the drive tab 25 of the transmission fork 24 or the opposite side 33 of said handle 2 forming the drive finger 26a adapted to cooperate with the drive tongue 25a of the slider 27. On the side 32, 33 with respect to which the latch 17 form drive finger 26, 26a, it adopts a position erased relative to the opposite side respectively 33, 32 of the handle 2. According to another embodiment of the control device 1 of the invention, the handle 2, pushed into its unlocked position 4 to bring the drive means 5 in one or the other unlocked position 7, 8 , has a vacuum stroke Cv with respect to said drive means 5 allowing it, from the unlocked position 4 to return to the locking position 3 without interaction on said drive means 5. In a particularly advantageous manner, the control device 1 comprises, in this case, elastic means for returning the handle 2 in its locking position 3. As illustrated in FIG. 10, this empty stroke Cv 30 may result from suitable disengaging means 34. According to a preferred embodiment, said disengaging means 34 consist of a transmission blade 35 which comprises the toothed sector 12 pivotally mounted on the same axis 11 as the handle 2 with a relative mobility relative to the latter, corresponding to the vacuum stroke Cv. More particularly, in this blade 35 is cut a semicircular sector 36 in which is engaged a lug 37 associated with the handle 2. Thus, when the drive means 5 are in their locking position 6 , and the handle 2 itself in its locking position 3, the lug 37 is in abutment with one of the ends 38 of the semicircular sector 36. By raising the handle 2, it results in the training of the transmission blade 35, and the interaction on the drive means 10 5 via the sector gear 12. Arrived in unlocked position 4 and releasing the handle 2, it can return to its locking position 3 in particular under the impulse of the elastic return means 39 and thanks to the relative mobility of the lug 37 along the semicircular sector 36. In the third embodiment, the drive finger 26; 26a acts on the tongue 25; 25a of the transmission fork 24, respectively of the slider 27, that in a direction of rotation of the handle 2, in particular in the unlocking direction of the latter. Also, it is free to regain its locking position 3, again by its own weight or under the impulse of elastic return means 39. Advantageously in this embodiment, once the handle 2 returned in its locking position 3, as the case the transmission fork 24 or the slider 27 is substantially locking means of the latch 17 in its selection position before unlocking control. In a preferred embodiment of the unlocking control method according to the invention, the drive means 5 are maintained in one or the other of the unlocked positions 7, 8 against the action of means of rotation. resilient return and control the return of said drive means 5 in their locking position 6 by releasing the action of the elastic return means. This process is particularly easy to implement thanks to the Cv empty stroke to initially bring the handle 2 back to its locking position 3, more precisely as soon as the action on this handle 2 is interrupted. .

Indeed, if the handle 2 was folded in this locking position 3 at the moment of the elastic return to the locking position 6 of the drive means 5 there could be a risk of accident, jamming finger or other. Referring now to FIGS. 17-21 illustrating a fourth embodiment of the control device according to the invention. The handle 2 is always rotated about an axis 11 on a base 10 forming a housing, the handle 2 being capable of occupying a locking position 3 and an unlocked position 4. The drive means 5 comprise a fork transmission 24 also rotatably mounted at the base 10 forming a housing about an axis 40 parallel to the pivot axis 11 of the handle 2, this transmission fork 24 extending under the base 10 of way able to act on a locking member such as an operating rod, this in a similar manner to the third embodiment. The drive means 5 further comprise, here, a slider 27a mounted to move in translation in the base 25 forming a housing and which is secured to the transmission fork 24 by means of a driving pin 28. Quantum to the control selector 9, it consists of a means for transforming the rotational movement of the handle 2 into a translational movement of the slider 27a in a first direction d1 when this control selector 9 is in a first position or in a direction opposite control d2 when it has been brought, in particular by the operator, in a second position.

According to an advantageous embodiment, this control selector 9 comprises a connecting rod 41 whose first end 42 is made integral with the handle 2 and a second end 43 is connected to the slider 27a. Advantageously, each of these ends 42, 43 is movable in translation along a slot respectively 44, 45 formed at the handle 2 and the slider 27a. These lights are thus defined for, when the end 42 of the rod 41 is pushed along the light 44 of the handle 2, this through an appropriate control member 46, that it results, according to the case, a traction on the slider 27a under the effect of the rotation of the handle 2 from its locking position 3 to its unlocked position 4 for a displacement of said slider 27a in the direction dl or, conversely, a thrust for a displacement 15 of said slide 27a in the opposite direction d2 generating under the impulse of the driving pin 28 a rotation of the transmission fork 24 in a first or a second direction corresponding to the first unlocked position 7 and the second unlocked position 8 of said drive means 5. Advantageously, the positions of the control member 46 of the control selector 9 on the handle 2 can be indexed. Preferably, if the connecting rod 41 is arched, through its ends 42, 43, in the slots 44, 45, during an unlocking control and therefore the rotation of the handle 2 since its 3 to its unlocked position 4, the relative mobility of the ends 42, 43 of the rod 41 in the slots 44, 45 substantially constitute the disengaging means 34 by which the handle 2 can return to its locking position 3 without interaction on the drive means 5, which can preserve their first or, as the case may be, the second unlocked position, in particular with regard to the transmission fork 24 of these drive means 5. Another special feature of the present invention, resulting from the characteristics of the control device 1 as described previously in different embodiments, is that on the base 10 forming box pe It is possible to mount resilient return control means of the drive means 5 in their locking position 6. Such control means, for example activated by appropriate triggering means, make it possible to envisage, in a simplified manner, a locking mechanism. Automatic carpentry type 10 door or window. Note also that instead of elastic return control means it is very easy to integrate the base 10 housing means for motorized management of the control device 1 according to the invention.

It should be noted that, whether they are elastic or motorized return control means, they are not only very easy to access, but, moreover, they do not constitute an additional bulk of joinery rebates. Of course, the invention is not limited to the examples illustrated and described above which may have variants and modifications without departing from the scope of the invention.
