Description

The invention relates to a cremone device for a door, window or the like, comprising a headrest comprising a front face and a rear face, on this headrest is reported a housing housing a drive mechanism comprising a follower adapted to cooperate directly or indirectly with a button or a handle for the displacement control, between at least one locking position and an unlocked position, of at least one operating rod mounted movably on the rear face of said headrest.

The invention also relates to a method of mounting a cremone device according to the invention on a carpentry type door, window or the like.

The present invention relates to the field of building hardware and relates, more particularly, to devices espagnolette or espagnolette-lock for doors, windows or the like.

Many cremone devices are already known as described above.

Thus, such a cremone device, often called cremone or espagnolette-lock, comprises a headrest to the rear of which is mounted at least one operating rod controlled in displacement, between a locking position and an unlocked position, by the intermediate of a control mechanism or drive taking place in a fitted housing attached to the rear of the headrest. Most often, this housing is housed in an engravure practiced in the edge before a carpentry, on either side of this engravure extends a groove inside which take position, mobile in translation, the or the operating rods. These are sheltered by the headrest.

It is understood, immediately, that at the end of their production line such cremones or espagnolette locks form a set whose elements are inseparable. At most, the headrest (s) and rods are cut at their ends for their adjustment in length compared to the size of a door-type opening, window or the like.

To this must be added that such cremones or espagnolette locks can be monodirectional or bidirectional. More exactly, the operating rod or rods extending above and / or below the housing housing the drive mechanism are capable of moving together in the same direction or in opposite directions during the controls. locking and unlocking. Obviously, the drive mechanism necessarily has characteristics adapted to provide such a monodirectional control or, as the case, bidirectional.

This drive mechanism comprises, usually rotatably mounted in the housing, a follower having in its center an opening for receiving a square maneuvering a handle or a control button. The follower can act directly or through trestles on the rods or maneuvering. Of course, this training mechanism can be supplemented by other means giving it additional functions. In particular, the follower can still be provided capable of acting on the tail of a latch bolt, just as, for a espagnolette-lock, the drive mechanism can integrate the means for a keyed control via of a barrel.

Anyway, when one comes to equip a carpentry such a locking mechanism type espagnolette or espagnolette-lock, it is necessary, in advance, to know what type of espagnolette or espagnolette lock and with which features this carpentry must be provided.

For example, at the time of installation of a joinery in a construction we can not decide, according to this implementation, whether the espagnolette or espagnolette-lock must be mono or bidirectional unless, of course, to equip the carpentry only at this time. However such a solution is not conceivable, because this installation of carpentry would be greatly complicated, besides the risks of Failure to operate the locking device would be significantly increased.

It is therefore understood that the carpenter, in order to equip the doors and windows that he designs with the most suitable locking fitting, must have in his inventory a large number of cremone devices which differ from each other. others through features that integrate their drive mechanism.

To this, it must be added that there is still a variety of cremone devices that differ only in size and in particular the depth of their housing. In particular, it has been possible to develop drive mechanisms capable of taking place in very shallow housings so as to limit that of the notching required to accommodate such a cremone device at the joinery level.

Other constraints can still influence this design of the housing and the driving mechanism of a cremone device. In particular, it is thus the implementation of the handle or the operating knob on a carpentry.

In this respect, reference will be made to the particular case of a joinery, of the window or French window type with two leaves and without a central mullion, one of these leaves, said of service, coming in recovery of the other , often said fixed.

In this case, the cremone device is implanted, most frequently, rabbet of the front upright of the service leaf. It also carries, usually, on the inner side and along its front post, a batten coming to overlap the joint plane between the service leaf and the fixed leaf. Carpentry gains in aesthetic aspect to the extent that this bathe defines, substantially, the plane of symmetry of the joinery.

Precisely, to maintain this perfect symmetry of the joinery, we sought to implant the barrel of the operating handle centrally at the level of this bathe. In this case, the handle of this handle extends necessarily in a plane located at the front of the headrest of the espagnolette device, or externally to the embedding groove of the latter.

To ensure the transmission of movement between this square maneuver offset from the control handle on the maneuver rod or rods extending at the rear of the headrest, so in the embedding groove, we imagined different solutions including a provided follower return mechanism adapted to take position in a specific notch in the carpentry, or even in the thickness of the pan.

He is still known, in particular by the document EP-1462594 , a cremone whose housing accommodates a follower whose axis of rotation is precisely in front of the plane of the operating rods, that is to say on the opposite side to the mounting groove for accommodating these rods . The follower meshes with a rack that includes one of the operating rods, the housing still accommodating an inverter in the form of a gear on which are meshing, diametrically opposite, the two operating rods s' extending, respectively, above and below the housing. In this case the headrest is subdivided into two portions of headrest respectively plug in the upper end and in the lower end of the housing.

In the document EP-1625269 it is proposed a cremone device of a similar design, the axis of rotation of the nut being located, not the groove side, but in front of the drive rod. The housing is, in this case, subdivided into two parts, a first housing part attached to the rear of the headrest is taking position in the recess groove, joinery rabbet, and a housing part fixed on the front of the headrest and welcoming, rotatably mobile, the follower. It traverses an oblong slot in said headrest to engage directly on the monodirectional type of operating rod. In this front part of the housing, the latter still has threaded openings for receiving the screw for fixing the operating handle. The two housing parts are reported by riveting on both sides of the headrest.

It follows from this state of the art that the cremone device must imperatively be pre-equipped, before mounting on a carpentry in this case before the implementation of the combination rail-headboard rabbet of this joinery, the housing and therefore the drive mechanism of this cremone device.

The present invention aims to overcome the disadvantages of this state of the art through a cremone device for door, window or the like, comprising a headrest having a front face and a rear face, on this headrest being reported a housing housing a drive mechanism comprising a follower adapted to cooperate directly or indirectly with a button or a handle for the displacement control, between at least one locking position and an unlocked position, of at least one movable drive rod of the side of the rear face of said headrest, characterized in that in the headrest is formed an opening traversed at least in part by the drive mechanism whose follower acts on at least one cooperating driver, through at least one drive finger and by interlocking, with at least one operating rod, during assembly of the housing on the front face of e the headrest.

• on rapporte sur la face avant de la têtière le boitier en assurant simultanément, par emboîtement et au travers du ou des doigts d'entrainement, la coopération entre le ou les entraîneurs avec la ou les tringles de manoeuvre.

The invention also relates to a method of mounting such a cremone device on a carpentry type door, window or the like, characterized in that:

• it is reported on the front face of the headrest housing by simultaneously ensuring, by interlocking and through the fingers or drive, the cooperation between the coaches or with the rods or maneuvering.

Finally, it is within the framework of an inventive step that it has been imagined that the housing housing the drive mechanism of a cremone device can equip it, even though the headrest-rod assembly is already mounted on a carpentry and that this box can then be attached to the front of the headrest.

In the case of a bi-directional cremone device, it also comprises at least one second driver cooperating with the first driver through an inverter, the second driver cooperating in turn, through at least one finger drive and by interlocking, with an operating rod, during assembly of the housing on the front face on the headrest.

The present invention will be better understood on reading the following description relating to exemplary embodiments illustrated in the accompanying drawings in which:

The invention as shown in the figures of the accompanying drawings relates to a cremone device 1 for a door, window or the like. In the figure 5 it has been illustrated an embodiment of this cremone device 1 in the In the present case, this cremone device takes up position in a recessed groove arranged for this purpose in rebate 3 of this leaf 2.

In any event, this cremone device 1 according to the invention comprises a headrest 4 on the side of the rear face 5 of which is slidably mounted at least one operating rod 6; 6A whose movement is controlled by means of a drive mechanism 7 housed by a housing 8 attached to the headrest 4.

As illustrated in the Figures 2 and 4 , this cremone device 1 can receive two operating rods 6, 6A, in this case when the cremone device comprises a bi-directional drive mechanism, able to communicate with one of the operating rods 6, s' extending on one side of this drive mechanism 7, a displacement in the opposite direction to that 6A extending on the other side of this drive mechanism 7, this during lock and unlock commands.

Of course and as it will appear in the context of the description of the Figures 1 and 3 , several operating rods 6; 6A can also equip a monodirectional cremone device 1.

As for the drive mechanism 7, it comprises, essentially, a follower 9 adapted to cooperate directly or indirectly with a knob or a handle, not shown. Thus, this follower 9, rotatably mounted in the housing 8, comprises, for example, an opening 10 adapted to receive a maneuvering square.

Moreover and as visible in Figures 3 and 4 , or in the figure 6 this opening 10 for receiving the operating square may be formed in a bushing 11 extending protruding on at least one of the lateral sides 12 of the housing 8.

According to another embodiment, not visible, the follower 9 may itself be extended, axially, on one side and / or on the other hand a maneuvering square on which is provided able to fit directly or indirectly, a handle or a control button. Again, such a square maneuver can extend laterally protruding from the housing 8.

According to a feature of the invention, on the opposite side to the rear face 5, the headrest 4 comprises a front face 13 on which the housing 8 is mounted, knowing that said headrest 4 further comprises an opening 14 crossing, at least in part, by the drive mechanism 7 to enter into cooperation with the or the operating rods 6, 6A.

As illustrated in Figures 3 to 6 , the housing 8 may have a first housing portion 15, located on the side of the front face 13 of the headrest 4 and a second housing portion 16 designed to extend through the opening 14 in the headrest 4.

The embodiments of the Figures 1 and 2 differ from those corresponding to Figures 3 to 6 in that the follower 9 is rotatably mounted in this second housing part 16, that is to say on the opposite side of the rear face 5 of the headrest 4. In short, this second housing part 16 is provided adapted to extend into the recess groove which usually comprises in rabbet 3 a leaf 2 equipped with such a cremone device 1.

In contrast, in the embodiments corresponding to Figures 3 to 6 , this follower 9 is rotatably mounted in the first housing portion 15 so that its pivot axis 17 is, relative to the headrest 4, the side of the front face 13 of the latter. This pivot axis 17 therefore extends in a plane parallel to the headrest 4, outside the embedding groove in which the cremone device 1 can be installed.

According to yet another particularity of the invention, the follower 9 acts on the operating rod or rods 6, 6A, via at least one driver 18 in particular slidably mounted in the housing 8 and cooperating, by interlocking and through at least one drive finger 19, with at least one operating rod 6, 6A.

In the embodiments illustrated in the drawings, it is systematically or the trainers 18, 18A which comprise a drive finger 19, 19A which engages in an opening 20 adapted in an operating rod 6, 6A. According to the invention, such openings may also be provided at the level of the trainer (s) 18; 18A for receiving a drive finger then equipping an operating rod 6; 6A.

Advantageously, this interlocking occurs during the mounting of the housing 8 on the headrest 4, preferably in a direction of interlocking perpendicular to the plane of the latter.

As illustrated in Figures 1 and 2 , the follower 9 may be provided with at least one ring gear portion 21 engaged with a rack 22 which is provided with a driver 18.

In the figure 1 , it is illustrated that coach 18 having two drive fingers 19, 19A extending perpendicular to the rear of the first housing portion 15 to cooperate with the or the operating rods 6, 6A.

Thus, in the case of a monodirectional cremone device, the operating rod 6 can be continuous to the right of the housing 8 and provided, as the headrest 4, an opening through which can extend at least in This opening in the operating rod 6 is then defined sufficient, not only to allow this passage of a portion of the drive mechanism 7, in this case the second housing portion 16 in the embodiments of Figures 1 and 2 but also to allow the operating rod to move from its locking position in its unlocked position and vice versa. Obviously, this operating rod can also be interrupted to the right of this housing 8, more particularly of the drive mechanism 7 and defined by two sections of operating rod 6, 6A controlled in the same direction of movement during locking and unlocking commands.

In the figure 2 illustrating a bi-directional cremone device, the follower 9 drives, through its toothed crown portion 21, the rack 22 of a first driver 18 which is engaged, through an inverter 23, with a second driver 18A able to move, under the action of a printed rotation to the follower 9, in a direction opposite to the driver 18. As visible, the inverter 23 may be in the form of a toothed wheel mounted in rotation in the first part of the housing 15, about an axis 24 parallel to the plane of the headrest 4 while being perpendicular to the latter. Thus, on this toothed wheel 23 mesh on both sides, using adapted racks, respectively, the coach 18 and 18A coach.

Obviously, one can imagine that the follower 9 comprises a ring gear on which meshes, diametrically opposed, these trainers 18; 18A, the follower performing the function of inverter.

As already mentioned above, Figures 3 to 6 schematically represent an embodiment where the follower 9 has its pivot axis 17 located at the front of the headrest 4. The follower 9 is rotatably mounted in the housing 8 which, in projecting the front face 13 of the headrest 4, is provided to take position in carpentry rabbet, for example, at the rebate set existing between the front posts of a service leaf and a fixed leaf of a door or window with two leaves. , without central mullion.

In order for this housing 8 to retain a very small thickness, the section of the follower 9 must itself be very small.

Specifically, by equipping this follower 9 with a sleeve 11 extending from one lateral side and / or the other 12 of the housing 8, the follower 9 may be in the form of a gear wheel 25 of reduced section, which can be inferior to that which should be respected to accommodate an opening 10 for receiving a maneuvering square.

However, to retransmit, through such a toothed wheel 25 of reduced section, a displacement of sufficient amplitude to the or the operating rods 6, 6A, this follower 9 acts, according to the invention, through at least one reversing gear 26 on a secondary drive gear 27 coaxially mounted with the follower 9 in the housing 8, more particularly in the first housing part 15, this secondary drive gear 27 cooperating directly or via inverter 23 on a trainer 18; 18A.

Advantageously, for a better distribution of the torque, thus efforts on the follower 9 in the form of a toothed wheel 25 of small section, two reversing gears 26, 26A can, thus, mesh, on both sides of a transverse median plane 28 to the housing 8, on this follower 9, each of these reversing gears 26, 26A acting, in turn, on a secondary drive gear 27, 27A engaged directly or via an inverter 23 with a coach 18; 18A.

Again, for bidirectional control, it will be possible to use an inverter 23 in a manner similar to the embodiment of FIG. figure 2 . On this inverter 23, in the form of a toothed wheel rotational axis parallel to that of the follower 9 can come to engage the coaches 18, 18A to ensure a displacement in opposite directions during the locking and unlocking commands.

Advantageous, the secondary drive gear 27; 27A is mounted in the housing 8 in a coaxial manner and integral in rotation with the reversing gear 26; 26A.

According to another feature of the invention, the headset-head assembly can receive, at different locations along its length, the means necessary to receive a housing 8 and its drive mechanism 7.

In this case, along the headrest 4 may be provided several openings 14 may be traversed at least in part by said drive mechanism 7, while as the operating rod or rods 6, 6A may be provided, in line with these openings 14, with means 20, for their cooperation with the drive mechanism 7 housed in said housing 8. This solution is more particularly adapted to a device monodirectional cremone 1.

With such a design an opening designed to receive a one-way cremone device can be equipped at different heights of a handle or a control button. This implementation of the handle or the control button can be adjusted according to that of the opening itself.

As already apparent from the foregoing description, the method of mounting such a cremone device 1 according to the invention is distinguished by the fact that the joinery is equipped, first of all, with a bead-headrest assembly. (s) on which is reported, in the front face 13 of said headrest 4, the housing 8 in which has been preassembled the drive mechanism 7.

The advantages that flow from the present invention are that it is possible to equip a joinery with a headrest-rod assembly (s), knowing that it is only at the last moment that the espagnolette device is completed through the housing accommodating the drive mechanism most suited to the desired features.

The carpentry manufacturer can therefore be content to have in its inventory, on the one hand, two types of headrest-rod assembly (s), one for a one-way control the other for a bidirectional control, or even that a single type of assembly composed of a headrest and two rods, the latter coming to cooperate through driving fingers 19, 19A with, as the case a coach 18 for a one-way control, or coaches 18; 18A separate for bidirectional control. On the other hand, this carpentry manufacturer may have at his disposal several types of housing 8 which are distinguished through their drive mechanism 7, some being monodirectional other bidirectional, among these drive mechanisms some with a follower 9 mounted in a second housing part set for extend through the headrest 4, other having a follower 9 whose axis 17 is mounted in the housing 8 so as to be located in front of the headrest 4 after mounting on the latter.

On one side, the headrest-rod sets (s) are not very fragile because, although elongated, they are devoid of any growth that can generate deformations. On the other hand, the manufacturer must store crates in which the casings of the drive mechanisms can be stacked without special precautionary measures.
