Description

1. Field of the invention

The field of the invention is that of equipment adapted to joinery.

More specifically, the invention relates to a closure device of a carpentry of an opening giving for example on the outside.

In the context of the invention, it may be in particular an aluminum carpentry, pvc (acronym of polyvinyl chloride), wood, steel, resin or any other material, whatever the manufacturing process.

The invention may in particular apply to openings of a building or a ship, rolling stock, vehicle, such as doors, windows or patio doors, with one or more leaves.

Furthermore, the invention can be implemented for the realization of new openings, or in rehabilitation of existing openings.

2. State of the art

A current trend in the design of outward-facing openings is to combat the heat losses generated by them. This trend is encouraged by national or supra-national regulations, such as, for example, in the European Economic Area, the new thermal regulation (RT 2010/12) concerning the improvement of the thermal performance of buildings and the Grenelle de l'Environnement in France.

It has been found that a thermally sensitive zone at the openings coincides with the handles. Indeed, when, for example, the opening of a door is equipped conventionally with an external handle with lock, it constitutes a zone of thermal bridge and privileged air permeability to the outside.

It has been proposed to use joineries commonly known as 'hidden doors', that is to say, a substantial part of which frame of the opening is hidden behind the frame but remains in contact with the frame when the opening is closed, to reduce losses by thermal bridges. These concealed opening woodworking techniques also make it possible to increase the bay clearing of the opening by approximately ten to twenty percent, in the case of glazed openings.

The document EP 1 524 378 A2 relates to a building window. In the closed state of the window, the casement of the window is covered on its outer surface in substance with a metal frame. The document WO 96/16245 A1 relates to a glazing panel intended to be mounted in a fixed window pillar. The document EP 1 580 369 A2 discloses a window comprising a manually operable drive device which is mounted on a leaf and a motorized drive device for a control bar bracket which is mounted on a frame. The document DE 93 15 055 U1 relates to a closure device for cabinet doors or cabinets in which is provided a handle on the door. The document EP 1 505 232 A1 describes a transmission between a lock and a espagnolette.

A disadvantage of these known techniques concealed carpentry is that they are complex to implement. They require in fact to provide a sash expander for integrating and deporting the lock on the outer or inner side of the frame of the opening, to open and close the opening of the outside and inside, for lack of to be able to mount a door handle, or window, on this external side, which would inevitably abut on the frame. The use of an expander has the further disadvantage of degrading the thermal performance and / or air permeability.

3. Objectives of the invention

The invention particularly aims to overcome the disadvantages of these techniques of the prior art.

More specifically, an object of the invention is to provide a closing technique of a joinery comprising at least one opening and a frame which is thermally efficient and optionally operable from the outside. Another object of the invention is to provide such a technique which is simple to implement. In at least one particular embodiment of the invention, an objective of the invention is notably to provide a technique that is inexpensive.

Yet another object of the invention is to provide such a technique which is efficient and robust.

4. Presentation of the invention

These objectives, as well as others that will appear more clearly later, are achieved by means of a closing device of a joinery with an opening on the outside, such as a door, a window or a French window, said joinery comprising at least one frame and an opening, comprising a handle mounted on the face turned towards the inside of said opening for actuating locking / unlocking means of said opening.

The invention therefore relates to the closure of any type of carpentry of an opening giving for example on the outside, the carpentry being open concealed or non-hidden.

According to the invention, such a device comprises means for actuating said locking / unlocking means comprising control means carried by the outer face of said frame, and means for selectively coupling said locking / unlocking means, allowing or preventing the locking / unlocking said leaf from the outside.

Thus, the invention proposes, in an unprecedented manner, a solution to the problem of locking / unlocking the sash from the outside, using means for coupling actuating means carried by the frame with locking means. / Unlocking the opening. In this way, most of the time, the (first) inward mounted handle and the outwardly mounted actuating means can be uncoupled, and thus thermally insulated. They are coupled only when it is necessary to open the joinery from the outside.

The control means may comprise a second handle carried by the frame or a lock housing or, alternatively, a second handle associated with a lock.

Advantageously, said control means (in the form of a second handle for example) are movable between a disengaged rest position, in which said coupling means are uncoupled from said locking / unlocking means, and at least one position engaged in which said coupling means are coupled to said locking / unlocking means.

Thus, when the second handle is in its rest position, for example after closing the opening and released the second handle, the element secured to the second handle, located on the outside, is uncoupled and therefore without contact with the means locking / unlocking of the opening, which eliminates, or at least greatly reduces, the thermal losses to the outside via the second handle.

Thus, the selective coupling means can take two positions: an active position in which the actuating means carried by the frame are coupled to the locking / unlocking means and an inactive position in which the actuating means carried by the frame are uncoupled from the locking / unlocking means.

According to a particular aspect of the invention, such a device may comprise return means for returning the coupling means in said disengaged position.

These return means, in the case of a second handle, may for example comprise one or more helical springs or spiral springs, one end of which is fixed to the frame.

Preferably, said return means and said coupling means are secured by friction.

This allows in particular to slide the coupling element secured to the second handle relative to the return means. In addition, when the second handle is released, the return means slow down the return of the second handle to its rest position. The pivoting of the second handle is therefore slower and more regular, which is appreciable in terms of safety and aesthetics and gives a character of good quality to the device.

In at least one embodiment of the invention, such a closure device comprises means for driving said coupling means in sliding in the vertical direction, actuated, able to be actuated by said control means (by a rotation of said second handle or a key in the lock).

In the case where the control means take the form of a lock, said drive means comprise a rack and a plurality of pinions ensuring a torque reduction

According to a particular embodiment of the invention, such a device comprises a support housing of said second handle housing said drive means, and configured to be fixed on said frame.

In a variant of this embodiment, the second handle and the drive means can be mounted in a housing formed directly on the frame.

In a particular embodiment of the invention, the direction of movement of the coupling means is selected by the direction of rotation of the key in the lock and the displacement of the coupling means is controlled by said second handle.

According to a particular aspect of the invention, said drive means comprise a selector oscillating between at least two coupling positions according to the direction of rotation of the key in the lock, said selector being mounted on a rack connected to said second handle .

At rest, the oscillating selector is in the neutral position and is not coupled with any other part of the frame thus ensuring a thermal break.

Advantageously, said drive means comprise at least one intermediate piece made of a material providing another thermal break.

The intermediate piece may be made of a material having a low thermal conductivity (thermal insulation), such as plastic for example.

In a particular embodiment of the invention, the control means comprise electromechanical means or motorized means.

The use of electromechanical or motorized means (such as in particular the servomotors, contactors) makes it possible to automate the locking / unlocking control of the opening. It is thus possible to substitute the second handle for a magnetic card reader or a remote control for example.

According to a particular aspect of the invention, said locking / unlocking means comprise a cremone bearing at least one roller.

Preferably, a coupling element secured to the second handle has at least one mortise portion configured so as to be able to grip a substantial portion of said roller, when said second handle is in said engaged position.

Thus, the coupling element of the second handle is effectively secured to the roller, which allows to operate the cremone up or down, by operating the second handle.

Advantageously, said opening has a complementary fixed handle on its outer face and / or its inner face.

Thus, when outside, and unlocked the opening by actuating the second handle, just grab the complementary fixed handle to push the door, and thus open the door or window. Conversely, this handle makes it possible to pull the opening towards you, to close it, before locking it from the outside with the help of the second handle.

In other variants of the invention, it is possible to fix the espagnolette bearing the (s) roller (s) on the frame and mount the latches on the opening. In this case, the control means may be in direct connection with the espagnolette.

It should be noted that, in the context of the invention, the opening can in particular be a leaf swinging, tilt-and-turn, sliding, tilt-and-slide.

6. Detailed description of several embodiments of the invention 6.1. General principle of the invention

As already indicated, the general principle of the invention is based on the implementation of coupling means of a member integral with actuating means carried by the frame with locking / unlocking means of the door, allowing a unlocking the opening by a simple operation of the actuating means.

The following are described as examples of implementation, several possible embodiments, without limitation.

6.2. First exemplary embodiment

The figure 1 illustrates a schematic view in horizontal section, at handle height, of an exemplary embodiment of the invention implemented on a swing door 10, the opening 11 is shown in closed position and locked.

The opening 11 consists of a frame 111 of aluminum, or other material, defining an inner facing and an outer bead between which a glass wall 112 is kept nested. It is mounted hidden by the frame 12, sealed in the wall 13. Seals 19 stuck on the frame 111 of the opening 11 and / or the frame 12 seal the frame when the opening 11 of the door 10 is closed, as shown in the figure 1 .

An interior door handle 14 is mounted on the frame 111 vertically or horizontally. A 90 ° rotation of this handle makes it possible to actuate a cremone 16, via a pinion 15, or via a cam in variants of this embodiment. The vertical sliding resulting from the espagnolette 16, illustrated by the arrow 21 on the side view along AA corresponding to the Figure 2A , makes it possible to lock or conversely to unlock the opening 11, by locking several rollers, two rollers 22A, 22B in this example, carried by the espagnolette 16 in latches (not shown) fixed vis-à-vis on the sidewall interior 121 of the frame 12.

The cremone 16 also carries a roller 17, designed to be actuated via actuating means mounted on the frame 12, as will be described in more detail below.

The Figure 2B is a view of the open door, of the embodiment of the invention presented on the figure 1 , on which we distinguish the inner handle 14 mounted on the frame 111 of the opening 11, the espagnolette 16 and the upper rollers 22A and lower 22B, and the roller 17. Note that the handle 14 is in a vertical position towards the bottom, the rollers 22A, 22B being in the high position (and unlocked latches of the frame) and the roller 17 is also in the up position.

In the embodiment of the invention described in relation to the Figures 1 to 6 , the actuating means comprise control means in the form of a control housing 130 in which are housed a lock (for example a European profile cylinder lock) 132, a set of gears (or gears) 131 whose axes are formed in the housing 130 and a rack 134.

As can be seen on the figure 3 , this housing 130 is an independent element designed to be fixed from the inside to the outer face 122 of the frame 12.

More specifically, the actuating means further comprise coupling means in the form of an element 116, of folded sheet for example or any other suitable material, which will be called thereafter "fork". A first end of the fork 116 is attached to the rack 134 of the housing 130 by means of two screws 152 in this example, or by a tenon and mortise assembly or by a jumper or by any other suitable fastening means.

The fork 116 is slidably mounted on the inner side 121 of the frame 12.

In particular, the fork 116 comprises at its second end, located inwardly, two upper notches 156A and 156B lower. When the door is closed, the fork 116 is in the neutral position illustrated on the Figure 6B and the roller 17 of the espagnolette 16 of the door 10 is housed in the upper notch 156A, in the low or locked position, without coming into contact therewith, as illustrated in FIG. Figure 6B . It should be noted that the roller 17 is not shown on the figure 5 and that no roller of the espagnolette is housed in the lower slot 156B in the illustrated example.

The fork 116 further comprises at its second end two upper and lower through holes in which are housed two pins 154A, 154B. These pins 154A, 154B can slide in an oblong slot 158A, 158B upper and lower of a guide piece 150 which is fixedly mounted on the inner side 121 of the frame 12, by two screws 159 or other suitable fastening means. The fork 116 can thus slide vertically with respect to the guide piece 150 along the inner side 121 of the frame 12.

In the embodiment of Figures 1 to 6 , the key (not shown) of the lock 132 acts as locking and unlocking means of the opening 11 from the outside, and is associated with an external pull handle 120 fixed on the opening 11.

So, as illustrated on the figure 4 , the opening 11 being in the closed position and locked (initial position), a rotation of the key in the lock 132 causes the rotation of the gearwheel 137 carried by the lock 132 which rotates the gear assembly (or pinions) 131 of the control unit 130, such a set 131 allowing in known manner a reduction of the torque.

The upper gear 133 of the assembly 131 meshes with the rack 134 so that the rotation of the pinions 131 causes the translational movement of the rack 134 upwards in the vertical direction (arrow 20).

The fork 116 being fixed to the rack 134, the fork 116 is also displaced in translation upwards (arrow 20 of the figure 3 ). The upper notch 156A is thus coupled to the roller 17 ( Figure 6C ) and therefore to the espagnolette 16 of the opening 11 which is consequently driven upwards. As a result, the rollers 22A, 22B are also driven upwards and extracted from their latches, and the handle 14 moves from the horizontal position to the vertical position downwards via the pinion 15, which unlocks the opening 11 It should be noted that the key can not then be removed from the lock 132.

Of course, the opening 11 being in the closed position and locked (initial position), it is also possible to unlock and open the door 11 from the inside.

In this initial position, the interior door handle 14 is in horizontal position, the rollers 22A, 22B are locked in their respective latches in the low position, the upper notch 156A is in the neutral position illustrated on the Figure 6B and the roller 17 is located at the bottom of the notch 156A.

As previously described in relation to the Figure 2A , the rotation of the handle 14 downwards causes the rollers 22A, 22B to move upwards (and thus to unlock the rollers 22A, 22B of their respective locks) and to move the roller 17 towards the top of the notch 156A ( Figure 6B ). The door can then be opened, the handle can remain in the low position ( Figure 2B ) or return to the horizontal position.

To lock the door from the inside, the opening 11 is closed and the handle 14 is moved to a horizontal position, which causes the displacement rollers 22A, 22B downwards, and thus their locking in their respective locks, as well as the movement of the roller 17 down the notch 156A ( Figure 6B ).

It should be noted that when the interior door handle 14 is used to lock or unlock the door, the fork remains in the neutral position illustrated on the Figure 6B and is not coupled to the roller 17 (in other words, does not come into contact with the roller 17) which is movable in the notch 156A. The fork is coupled to the roller during the locking or unlocking of the opening through the 132 lock outside. Thus, the invention proposes, in an unprecedented manner, a solution to the problem of unlocking the door from the outside, using means for coupling actuating means carried by the frame with locking / unlocking means of the opening. In this way, most of the time, the first inwardly mounted handle and the outwardly mounted actuating means can be uncoupled, and thus thermally insulated. The first handle and the actuating means are coupled only when it is necessary to open the joinery from the outside.

Thus, in the case where we would like to close and lock the door from the outside after having opened from the inside, it is necessary to close the door by keeping the handle 14 low and to lock the lock 132 outside the door. using the key. This lock 132 lock causes the passage of the fork 116, and therefore the notch 156A, the neutral position ( Figure 6B ) at the low position ( Figure 6A ), the notch 156A then being coupled to the roller 17 which is thus moved downwards which then causes the rollers 22A, 22B to slide downwards into the latches and lock them. The door being closed and locked, the key, to be removed from the lock 132, must be turned in the opposite direction to the central position and then removed. This action moves the rack 134 and therefore the fork (and the notch 156A) which then returns to the neutral position ( Figure 6B ) and disconnects from the roller 17, the roller 17 then being down the notch 156A.

In the case where it is then desired to open the door from the outside, it is necessary to insert the key in the lock 132 and unlock the lock by turning the key, which causes the displacement of the notch 156A of the position neutral ( Figure 6B ) to the high position ( Figure 6C ), the notch 156A then being coupled to the roller 17, thus moving it upwards. This then causes the sliding (extraction) of the rollers 22A, 22B out of strikes and their unlocking, and the passage of the handle from the horizontal position to the vertical position downwards. The key, to be removed, must be turned in the opposite direction causing the notch 156A to move to the neutral position ( Figure 6B ) and its uncoupling of the roller 17, the roller 17 then being at the top of the notch 156A.

The user can therefore open the door using the handle 120, go inside, close the door and lock it from the inside by moving the handle 14 in a horizontal position, which causes the rollers 22A, 22B to move. down the corresponding keeper and lock the door.

It should be noted that depending on the espagnolette 16 used and the direction of rotation of the inner handle 14, the positions "locked" and "unlocked" indicated on the Figures 6A to 6C can be reversed.

6.3. Second embodiment

The figure 7 illustrates a horizontal sectional view, at handle height, of another exemplary embodiment of the invention implemented on a swing door 10, the opening 11 is shown in closed position and locked.

In the same way as in the first embodiment described above, the opening 11 consists of a frame 111 of aluminum or other material defining an inner facing and an outer bead between which a glass wall 112 is kept nested. It is mounted hidden by the frame 12, sealed in the wall 13. Seals 19 glued to the frame of the opening 111 and / or the frame 12 seal the frame when the opening of the door is closed, as shown on the figure 1 .

An interior door handle 14 is mounted on the frame 111 vertically or horizontally. A 90 ° rotation of this handle makes it possible to actuate a cremone 16, via a pinion 15, or via a cam in variants of this embodiment. The vertical sliding resulting from the espagnolette 16, illustrated by the arrow 21 on the side view corresponding to the figure 2 , makes it possible to lock or conversely to unlock the opening 11, by blocking the rollers 22 carried by the espagnolette 16 in latches (not shown) fixed vis-à-vis the inner side 121 of the frame 12.

The espagnolette 16 also carries a roller 17, designed to be actuated via a second handle 110 mounted on the frame 12, as we will see in more detail later.

When the handle 110 is released, it takes the disengaged disengaged position illustrated on the figure 7 under the influence of the disengaging mechanism, or coupling, 113. Under the action of the return spring 118, whose base is fixed to the frame 12, the drive pinion 114, the rack 115 and the element 116 are having in the form of a rod fixed to the rack and a mortise end portion 117 receded with the handle 110, and the element 116 is uncoupled from the roller 17 carried by the espagnolette 16 locking / unlocking.

We present with reference to the figure 8 a position in which the second handle is engaged.

In this engaged position, the handle 110 has pushed the pinion 114, the rack 115 and the element 116 towards the espagnolette 16. The return spring 118 is compressed under the action of the rack 116 which pushes on its tray 119. The mortise portion 117, comes into contact with the roller 17, with its fork profile, about half of its contour. The element 116 is thus coupled to the roller 17 and therefore to the espagnolette 16.

By turning the second handle 110 engaged downwardly in this embodiment of the invention, the pinion 114 is rotated. This pinion 114 meshes with the rack 115 and moves it upwards. The element 116 slides therefore upwards, in the vertical direction, and drives the espagnolette 16 to which it is coupled upwards. As a result, the rollers 22 are extracted from their latches, which unlocks the opening 11.

Note that, in this embodiment, there is also provided a complementary fixed handle 120 on its outer face of the opening, to allow the user to push the opening inwards after unlocking the opening using the second handle 110.

When the opening is open, the element 116 returns to its original position by releasing the handle 110 which rotates under the action of its internal spring. This displacement is carried out progressively because of the frictional resistance of the plate 119 on the rack 115.

6.4. Third embodiment

We present in relation with the figure 9 , another exemplary embodiment of the invention in which the drive gear 114 and the rack are housed in a housing 31 supporting the second handle 110.

As can be seen on the figure 9 , this housing 31 is designed to be fixed on the frame, for example by means of screws, rivets, by gluing, by welding or by any other suitable fastening means. Seals 121 bonded to the housing 31 and / or the frame 12 seal the frame.

6.5. Fourth embodiment

We present in relation with the figure 10 , another exemplary embodiment of the invention in which the second outer handle 110 is mounted on a housing 31, itself mounted on the frame 12. The handle 110 is, in this embodiment, equipped with a barrel or key cylinder 132. The figure 10 represents the second handle 110 in an engaged position which is obtained by rotation of the key in the barrel 132. Indeed, the rotation of the key allows to actuate a clutch finger 136, via a clutch 135, which under the action of the spring 138 is engaged with a cam 139 rotatably mounted on an axis 141 of the housing 31.

An element 116 in the form of a drive finger is housed in an oblong orifice of the cam 139. This element 116 is integral with the mortise 117 which is in contact with the roller 17, thanks to its fork profile. . The element 116 is thus coupled to the roller 17 and thus to the cremone 16. By turning the second handle 110 engaged from the horizontal position to the vertical position downwards, the cam 139 rotates a quarter turn and the mortise 117 , via the element 116, is guided in sliding (by a linear guide G) vertically upwards, causing the espagnolette 16 upwards, via the roller 17. As a result, the rollers 22 are extracted from their latches, this which unlocks the opening 11.

6.6. Fifth embodiment

We present, in relation to the figure 11 , another exemplary embodiment of the invention, in which the outer handle 110 and the locking key cylinder 132 are housed in an outer control housing 130, which is an independent element designed to be mounted on the outer face 122 of the frame 12.

In this embodiment, the actuating means comprise coupling means, in the form of a fork 116 which is slidably mounted on the inner side 121 of the frame 12. The fork 116 comprises a notch 156 in which is accommodated the roller 17 of the espagnolette 16.

As will be detailed later, the movement of the roller 17 is controlled by the pivoting handle 110, and not by the key of the cylinder 132, which serves only to select the direction of movement of the fork 116.

We distinguish on the figure 11 the connection between the fork 116 and the housing 130. Thus, a sliding plate D mounted in the housing 130 is connected to the fork 116 by means of an intermediate piece PI which is fixed on the plate D and secured to the fork 116 by a connection type mortise and tenon for example. The intermediate piece PI is made of plastic, for example, which ensures a first thermal break. According to one variant, several intermediate pieces (made of plastic or any other suitable material) are provided to ensure such a thermal break.

The connection between the fork 116 and the housing 130 may be concealed behind a cover (not shown on the figure 11 , such a cache being however represented on the figure 3 ), or hubcap, which provides an aesthetic solution when the door is open. It also guarantees the non-intrusion of insects, dust or cleaning product in the mechanism of the housing 130.

As illustrated on the figure 11 , the operating handle 110 is housed in a housing of the housing 130. At rest, the outer surface of the operating handle 110 is vertical and preferably flush with the outer surface of the housing 130. The horizontal axis A1 of articulation of the operating handle 110 is located towards the top of the housing. The handle does not extend over the entire length of the housing thus defining an opening or gripping area 141 located at the bottom of the housing. Alternatively, a side notch may be provided to grip the handle.

The working stroke of the handle 110 is from the bottom up ( figure 11 ), by lifting.

From the lifting of the handle 110 and the selection (clockwise or counterclockwise) made from the key of the barrel 132, it is possible to move the fork 116 upwards or downwards, and thus to achieve locking or unlocking the opening of the door.

When the handle 110 is moved by lifting, it can be provided a dead stroke during which the movement of the handle 110 has no influence on the movement of the fork 116, and a working stroke that follows the dead stroke, and which is located around the horizontal position of the handle 110. This working stroke corresponds to the travel required to move the roller 17 to full effort.

However, it should be noted that, in the case where the key is not inserted into the barrel 132, the working stroke of the handle 110 is free. It does not cause displacement of the fork 116, and therefore of the roller 17.

Indeed, to move the fork 116, it is necessary, before raising the handle 110, to select with the key the rise or fall of the fork 116 by a clockwise or counterclockwise rotation respectively of the key.

The handle can be folded towards the rest position shown on the figure 11 , by manual push, or even by spring.

A visual indicator (a color code for example) can be provided to indicate the high or low position of the range.

The Figures 12A-12D are schematic views, at handle height, of the embodiment of the invention presented on the figure 11 .

• le barillet 132 dans lequel une clé (non représentée) peut être introduite, le barillet 132 comprenant un cylindre à dents CD engrenant avec deux crémaillères came C1, C2 situées de chaque côté du barillet 132 ;
• une crémaillère B qui engrène avec un pignon denté P de la poignée 110 pivotante autour de l'axe de rotation A1 ;
• une roue dentée R monté sur la crémaillère B et pivotante autour d'un axe A3. Les extrémités inférieures des crémaillères came C1 et C2 viennent en butée contre deux dents opposées de la roue dentée R. La roue dentée R peut ainsi être entrainée en rotation dans le sens horaire ou antihoraire selon que la crémaillère came C2 ou C1 respectivement est déplacée en translation vers le bas ;
• un sélecteur S monté sur la crémaillère B. Le sélecteur S est monté oscillant autour d'un axe A2 et peut ainsi basculer à droite ou à gauche selon que la roue dentée R tourne dans le sens horaire ou antihoraire respectivement. Au repos (comme illustré figures 11, 12A à 12D), le sélecteur S est en position neutre N et n'est pas en contact avec une crémaillère A ou la platine D ce qui permet une deuxième rupture de pont thermique ;
• un engrenage E pivotant autour d'un axe A4 et s'engrenant d'un côté avec la crémaillère A et de l'autre côté avec la platine D.

In these figures, the elements mounted in the outer control box 130 are distinguished, namely:

• the barrel 132 in which a key (not shown) can be inserted, the barrel 132 comprising a CD toothed cylinder meshing with two cam racks C1, C2 located on each side of the barrel 132;
• a rack B which meshes with a pinion gear P of the handle 110 pivoting about the axis of rotation A1;
• a toothed wheel R mounted on the rack B and pivoting about an axis A3. The lower ends of the cam racks C1 and C2 abut against two opposite teeth of the toothed wheel R. The toothed wheel R can thus be rotated clockwise or counterclockwise depending on whether the cam rack C2 or C1 respectively is moved into position. downward translation;
• a selector S mounted on the rack B. The selector S is mounted oscillating about an axis A2 and can switch right or left depending on whether the gear R rotates clockwise or counterclockwise respectively. At rest (as illustrated figures 11 , 12A to 12D ), the selector S is in neutral position N and is not in contact with a rack A or platinum D which allows a second thermal break;
• a gear E pivoting about an axis A4 and meshing on one side with the rack A and on the other side with the plate D.

To move the fork 116, it is necessary before raising the handle 110 to select with the barrel key the raising or lowering of the fork 116 by a clockwise or counterclockwise rotation of the key in the barrel 132.

The clockwise or counterclockwise rotation of the key in the barrel 132 causes the rotation of the toothed cylinder CD and the downward movement of the cam rack C1 or C2. Thus, when the cam rack C2 is moved downwards, the toothed wheel rotates clockwise, the selector S rotates counterclockwise and mates with the rack A (position -). When the cam rack C1 is moved downwards, the toothed wheel rotates counterclockwise, the selector S rotates clockwise and mates with the plate D (position +).

When the selector S is coupled with the rack A and the handle 110 is raised, the rack B, which carries the selector S, slides downward which causes the sliding down of the rack A, and therefore the rotation of the gear E which then causes the displacement in translation upwards of the plate D. The plate D being connected to the fork 116 by means of the intermediate piece PI, the fork 116 is also displaced in translation upward resulting in the moving the roller 17 in the same direction.

When the handle 110 is folded down, the rack B, and therefore the selector S, slide upwards (the selector is disengaged from the rack A), but the fork 116, and therefore the roller 17, remain in the same position.

When the selector S is coupled with the plate D and the handle 110 is raised, the rack B which carries the selector S slides down which causes the sliding down of the plate D. The plate D being connected to the fork 116 through the intermediate piece PI, the fork 116 is also moved in translation downward driving the roller 17 in the same direction. When the handle 110 is folded down, the rack B, and therefore the selector S, slide upwards (the selector is disconnected from the plate D), but the fork 116, and therefore the roller 17, remain in the same position.

When the key is returned to the neutral position in order to possibly be removed from the barrel 132, the two cams C1 and C2 return to the neutral position (as illustrated figures 11 , 12A to 12D ). The selector S then returns to the neutral position N, thus excluding (or prohibiting) any possibility of movement of the fork 116 and the roller 17.

Thus, to move the fork 116 and therefore the roller 17, it is first necessary to select with the key the rise or fall of the fork 116 by a clockwise or counterclockwise rotation of the key in the cylinder respectively. Once this selection of the rise or descent has been effected, the actuation of the handle upwards then makes it possible to move the fork 116 in the selected direction, causing the displacement of the roller 17 and therefore the espagnolette 16.

The first and second thermal bridge breaks according to this embodiment allow a greater thermal bridge break than in other embodiments described above.

6.7. Sixth embodiment

We present, in relation to the figure 13 , another exemplary embodiment of the closing device of an outwardly swinging door 210, said hinged door comprising a frame 212 and an opening 211 not hidden which is shown in closed position and locked.

The opening 211 consists of a frame 2111 made of aluminum, or other material, defining an inner facing and an outer bead between which a glazed wall 212 is kept nested. The opening 211 is mounted not hidden by the frame 12, which is sealed in a wall (not shown).

Seals 219 glued to the frame 2111 of the opening 211 seal the frame when the opening 211 of the door 210 is closed, as shown in FIG. figure 13 .

An interior door handle 214 is mounted on the frame 2111 horizontally. A control box 2130 is internally fixed on the outer face 2122 of the frame 212.

The actuating means comprise coupling means in the form of a fork 2116 whose one end is fixed to the rack 2134 of the housing 2130, the fork 2116 being slidably mounted on the inner side of the frame 212.

As described previously, the displacement of the fork 2116 causes the roller 222A carried by the espagnolette 216 of the opening 211 to move.

Note that an outside pull handle 2120 is fixed on the opening 211.

6.8. Seventh embodiment

We present, in relation to the figure 14 , another embodiment of the closing device of a French window, giving on the outside, and comprising a frame 312 and an opening not hidden. The frame 312 and the opening 311 consist of a frame in which a glass wall 3112A, 3112B respectively is kept nested.

Seals 3219 glued to the frame 3111 of the opening 311 seal the frame when the opening 311 of the door 310 is closed, as shown in FIG. figure 13 .

An interior door handle 314 is mounted on the frame 3111 horizontally. A control box 3130 is attached internally to the outer face 3122 of the frame 312.

The actuating means comprise coupling means in the form of a fork 3116 whose one end is fixed to the rack 3134 of the housing 3130, the fork 3116 being slidably mounted on the inner side of the frame 312.

As described previously, the movement of the fork 3116 causes the roller 322A carried by the espagnolette 316 of the opening 311 to move.

Note that an outside pull handle 3120 is fixed on the opening 311.

6.9. Other optional features or variants of the invention

In variants of the embodiments detailed above, it may also be envisaged, without departing from the scope of the invention, to substitute electromechanical control for the control means (second handle or control box), so as to automate the locking / unlocking the opening, and in some cases, integrating it into a home automation system.

In variants of the invention, it is possible to fix the espagnolette bearing the (s) roller (s) on the frame and mount the latches on the opening.

It can also be provided in other variants of the invention, to equip the frame of an additional lock, for example a pin lock or a pump lock, for security.

It should also be noted that the invention can equip doors, windows or the like, with one or more leaves, whose opening is flapping, tilt-and-turn, sliding, tilt-and-slide.
