Description

BACKGROUND OF THE INVENTION The field of the invention is that of equipment suitable for joinery. More specifically, the invention relates to a closing device of a concealed opening joinery with 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 thus been proposed to use joineries commonly referred to as 'hidden sashes', that is to say of which a substantial part of the frame of the sash is hidden behind the frame but remains in contact with the frame when the sash 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. 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. 3. OBJECTIVES OF THE INVENTION The object of the invention is in particular 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 concealed opening joinery which is thermally efficient and 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. Description of the invention These objectives, as well as others which will appear more clearly later, are achieved by means of a closure device of a joinery with an opening on the outside, such as a door, a window or a French window, said joinery comprising a frame and a concealed opening, comprising a first handle mounted on the face turned towards the inside of said opening allowing to actuate locking / unlocking means of said opening .

The invention therefore relates to the closure of joineries with hidden opening. 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 inwardly 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 20 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 engaged position 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 this second handle, the element secured to the second handle, located on the outside, is uncoupled and therefore without contact with the means for locking / unlocking the leaf, 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 comprises 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 25 in sliding in the vertical direction, actuated, able to be actuated by said control means (by a rotating 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 providing 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 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, turning the second handle. Advantageously, said opening has a complementary fixed handle 25 on its outer 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 by means of the second handle.

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. 5.

Detailed Description of Four 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 means for coupling a member integral with actuating means carried by the frame with locking / unlocking means. the opening, allowing unlocking of the opening by a simple operation of the actuating means. Four exemplary embodiments are described below, as non-limiting examples. 6.2. First exemplary embodiment Figure 1 illustrates a schematic horizontal sectional view, at handle height, of an exemplary embodiment of the invention implemented on a swing door 10, the opening 11 is shown in FIG. closed and locked position. 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 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 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 Figure 2A, allows locking 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 inner side 121 of the frame 12. The espagnolette 16 also carries a roller 17, intended to be actuated via actuating means mounted on the frame 12, as will be described in more detail later. FIG. 2B is a view of the open door, of the embodiment of the invention shown in FIG. 1, on which is distinguished the inside handle 14 mounted on the frame 111 of the opening 11, the espagnolette 16 and the rollers 22A and lower 22B, as well as the roller 17. Note that the handle 14 is in the vertical position downwards, the rollers 22A, 22B being in the up position (and unlocked latches of the frame) and the roller 17 is also in position. high position. In the embodiment of the invention described with reference to FIGS. 1 to 6, the actuating means comprise control means in the form of a control box 130 in which a lock is housed (for example a lock with a European profile) 132, a set of gears (or gears) 131 whose axes are formed in the housing 130 and a rack 134. As can be seen in FIG. 3, this housing 130 is an element 25 independent designed to be fixed from the inside on the outer face 122 of the frame 12. More specifically, the actuating means further comprises coupling means in the form of an element 116, folded sheet for example or any another 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 shown in Figure 6B and the roller 17 of the espagnolette 16 of the door 10 is housed in the upper slot 156A, in the low or locked position, without entering in contact therewith as shown in Figure 6B. It should be noted that the roller 17 is not shown in Figure 5 and no roller of the espagnolette is housed in the lower slot 156B in the example shown. 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 FIGS. 1 to 6, the key (not represented) of the lock 132 acts as a means locking and unlocking the opening 11 from the outside, and is associated with an external pull handle 120 fixed on the opening 11.

Thus, as illustrated in 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 gear 137 carried by the lock 132 which rotates the set of gears (or pinions) 131 of the control unit 130, such a set 131 allowing 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 FIG. 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 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 inside. In this initial position, the interior door handle 14 is in the 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 shown in FIG. 6B and the roller 17 is located at the bottom of the notch 156A.

As described above with reference to FIG. 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 up 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 rollers 22A, 22B to move 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 shown in FIG. 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 thus the notch 156A, the neutral position (Figure 6B) to the low position (Figure 6A), the notch 156A then being coupled to the roller 17 which is then moved down which then causes the sliding of the rollers 22A, 22B down in the strikes and their locking. 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 thus the fork (and the notch 156A) which then returns to the neutral position (Figure 6B) and disconnects 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 (FIG. 6B) towards the high position (FIG. 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 which causes the displacement of the notch 156A in 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. 6.3. Second Embodiment FIG. 7 illustrates a horizontal sectional view, at handle height, of another exemplary embodiment of the invention implemented on a swinging door 10 whose opening 11 is shown in the 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 concealed 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 in 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 FIG. 2, makes it possible to lock or vice versa to unlock the opening 11, by blocking the rollers 22 carried by the espagnolette 16 in strikes. (not shown) fixed vis-a-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 it in more detail later. When the handle 110 is released, it takes the disengaged rest position shown in Figure 7, under the influence of the disengagement mechanism, or coupling, 113. Under the action of the return spring 118, the base is fixed to the frame 12, the drive pinion 114, the rack 115 and the element 116 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. With reference to FIG. 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 due to its fork profile over about half of its contour. The element 116 is thus coupled to the roller 17 and therefore to the cremone 16. By turning the second handle 110 engaged downwards 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 thus slides 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, so to allow the user to push the door inwards after unlocking the door with the second handle 110. When the door is open, the element 116 returns to its original position by releasing the handle 110 which turns 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 Another embodiment of the invention is shown in relation to FIG. 9, in which the drive pinion 114 and the rack are housed in a housing 31 supporting the second handle 110. As can be seen in FIG. see 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 In another embodiment of the invention, the second external handle 110 is mounted on a housing 31, itself mounted on the frame 12. The handle 110 is , in this embodiment, equipped with a cylinder or key cylinder 132. Figure 10 shows the second handle 110 in an engaged position which is obtained by rotation of the key in the barrel 132. In fact, the rotation of the key can 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. Other alternative 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 an electro-mechanical control for the control means (second handle or control box), so as to automate the locking / unlocking control of the opening, and in some cases to integrate it into a home automation system. In other variants of the invention, it may also be provided to equip the frame of an additional lock, for example a pin lock or a pump lock, for safety.

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