The invention relates to a device for controlling the opening of a door or window opening towards the outside, comprising:

• - a housing attached to the lower cross member of the sleeping frame and serving as a housing for a mechanism, actuated by a crank, to control the rotation of an operating arm provided, at its end, with a roller sliding in a rail integral guidance of the opening;
• - protective means to prevent access to the operating arm, in particular at the start and at the end, respectively, of opening and closing of the opening;
• - And means to block it regardless of its angular position relative to the frame.

This invention will find its application in the building industry and will be more particularly used within the framework of door or window with opening towards outside, known as in English.

The devices enabling the opening and closing of the opening of a door or window from the sleeping frame to be controlled are most frequently used in countries where the humidity is particularly high during certain periods of the year. year, favoring the development of flying insects. In fact, due to these conditions, the natives are obliged to double all the glass surfaces with a mosquito net to prevent these flying insects which abound from entering their homes. However, due to the opening to the outside of the door, this screen can only be placed on the internal side of the door or window. Such a mosquito net is generally formed by a curtain, the frame of which is sufficiently ventilated to promote the circulation of air while preventing flying insects from passing through. Furthermore, a frame attached to the frame of the door or window keeps this curtain taut.

This mosquito net having its use only during part of the year, it is, in most cases, removable. However, to avoid the successive assembly and disassembly of these mosquito nets at each opening operation, these doors or windows are provided with a control device making it possible to actuate said opening from a distance and, in particular, from the lower cross member of the sleeping frame. In addition, during the periods when the flying insects are particularly numerous, it is preferable not to proceed, at any time, to the dismantling of the mosquito nets to prevent one of these insects from entering the dwelling.

Already known, in particular from documents US-A 4 392 330 and US-A 1 724 011, (the latter correspond to the preamble of the claim) a device for controlling an opening of a door or window opening towards the exterior showing the elements mentioned above. Thus, this control device comprises a housing fixed to the surface of the lower crossmember of the sleeping frame, said housing containing a mechanism making it possible to control in rotation an operating arm pivotally mounted in the housing and connected to the leaf. Said mechanism consists of an endless screw or toothed wheel driven in rotation by a crank and cooperating with the toothing produced at the end of the operating arm housed in the housing. Due to the arrangement on the lower crossmember of the frame, the axis of rotation of the worm of this control device forms, in some cases, an angle of about thirty degrees with the horizontal to facilitate the operation of the crank and that the window sill does not interfere with the rotation of the latter.

This type of known control device is generally associated with a set of compass arms disposed in the rebate of the sleeping frame or of the opening allowing it to be given not only a rotation about a vertical axis passing through its upright. rear, but also a translation, parallel to the plane of the fixed frame of this axis of rotation of the opening. The advantage of the combination of these two movements consists in shifting the rear upright of the opening laterally relative to the upright of the sleeping frame to define a space allowing access to the external face of the glazed surface. This feature is of interest especially when the window is located at a certain height from the ground and when it is, therefore, difficult to access for cleaning its glass surface.

Despite the advantages, mentioned above, of known control devices, the latter are not however devoid of a certain number of drawbacks. When the mosquito nets are removed from the sleeping frame, access to the mechanism and, in particular, to the operating arm of this control device is particularly facilitated. However, this increases significantly, the risk of accident, for example, the trapping of a finger, generally due to the carelessness or negligence of the user.

To remedy this drawback, a control device has been designed which substantially takes up the characteristics of those described above, but the mechanism of which, like the operating arm, are inserted in the rebates of the frame and of the leaf. However, this type of control device is generally of higher cost due in particular to the additional machining in said rebates imposed by this arrangement of the various mechanical elements.

Another drawback presented by all of these control devices for an opening opening to the outside consists in a weakness in terms of security in the event of a break-in. In the case of a French-style door or window, the latter comprise, in certain cases, fittings of the tilt-and-turn type, offering the possibility of keeping the opening in a half-open position while offering a minimum of security against actions. of a haddock. In contrast, in the case of opening pivoting towards the outside, the mechanical connection, connecting the control device and said opening when the latter is in the open position, is only constituted by the operating arm. Therefore, and due to the large lever arm, the control device can only have a low resistance and would deteriorate quickly if it acts on the upright before the door. This drawback persists even in the case of use of locking means, as described in document US-A 1,724,011, intervening at the rear end of the operating arm to immobilize the latter and, consequently , opening it in different angular positions relative to the frame.

The solution to the problems posed above would consist in installing the control device as close as possible to the front upright of the opening, thereby reducing the lever arm. Under these conditions, the angle of rotation which it would be possible to impart to the opening element by means of this control device would be greatly limited and, in all cases, less than ninety degrees.

The object of the present invention is to remedy all of the aforementioned drawbacks. Thus, the invention as characterized in the claims, solves the problem of creating a device for controlling an opening of a door or window opening towards the outside, comprising:

• - a housing attached to the lower cross member of the frame and serving as a housing for a mechanism, actuated by a crank, to control the rotation of an operating arm provided at its end with a roller sliding in a rail integral guide of the opening;
• - protective means to prevent access to the operating arm, in particular, at the start and at the end, respectively, of opening and closing of the opening;
• - And means for locking the latter whatever its angular position relative to the sleeping frame (3);
• - Said protection means being constituted by a profile in the form of a gutter open laterally, composed of two horizontal wings connected by a vertical flank, said profile being applied to the internal face of the lower cross member of the frame in the closed position of the opening the upper wing covering, in full, the guide rail to prevent, in association with the latter, access to said operating arm, in particular, at the start and at the end, respectively, of opening and closing of the opening;
• - The means for locking the latter in different angular positions being constituted by locking means associated with the protection means and comprising a locking element, such as a barrel or the like.

Other features of the invention are defined by claims 2 to 9.

The advantages obtained thanks to this invention consist essentially in that the protective means avoid any risk of accident, such as pinching of a finger or the like, during the opening of the door. Furthermore, the locking means make it possible to avoid repercussions on the mechanism of the device for controlling a force applied to the front upright of the opening. Furthermore, due to their proximity to said upright before the opening, these locking means considerably reduce the importance of the forces that it is possible to apply to them, while allowing the opening of the opening at an angle substantially equal to, or even greater than ninety degrees.

We refer to figure 1.

The control device 1, according to the invention, is used in particular in the context of a door or window opening towards the outside. FIG. 1 schematically represents a window 2, the sleeping frame 3 of which is provided at its lower cross member 4, with such a control device 1. The objective of the latter consists in operating the opening element 5 from the inside of the house and without the user having to intervene directly on said opening 5.

The control device 1 consists of a housing 6 serving as a housing for a mechanism actuated by a crank (not shown) for controlling the rotation of an operating arm 7 connected to the leaf 5. Advantageously, the housing 6 and fixed, on the surface, to the lower cross member 4 of the fixed frame 3. This arrangement avoids the machining of the rebate of this lower cross member 4 as well as of the rebate of the lower cross member 8 of the leaf 5.

The mechanism of the control device 1, to which reference has been made above, has not been shown in the various figures since it is perfectly known in the state of the art. However, it should be noted that this mechanism consists of an endless screw capable of driving in rotation, either by means of a pinion, or direct ment, the operating arm 7, the direct drive of the latter being obtained by means of a toothing machined at its end introduced into the housing 6. A crank (not shown) makes it possible to actuate said worm. To this end, the housing 6 includes, in its cover 9, a boss 10 provided with an orifice 11 through which opens one end of the worm, on this end being attached, by any fixing means, the crank cited above. To prevent the window sill from interfering with the rotation of this crank during the operation of the opening 5, the axis of rotation 12 (see Figures 1, 2 and 3) of the worm forms an angle about thirty degrees with the horizontal.

The connection between the opening 5 and the operating arm 7 consists of a roller 13 secured to the end 14 of the latter and sliding in a guide rail 15 fixed in the wall on the lower cross member 8 of the opening 5 .

As shown in Figure 1, the control device 1 and in particular the housing 6 is fixed nearby. mity of the rear uprights 16, 17 respectively of the frame 3 and the opening 5. Due to this arrangement, the control device 1 is able to give said opening 5 a rotation of an angle of approximately ninety degrees.

According to the invention, the control device 1 comprises protective means 18 whose function consists in prohibiting access to the operating arm 7, in particular at the start and at the end, respectively of opening and closing of the opening 5 .

We refer to Figures 1 to 3.

According to a first embodiment, these protection means 18 are constituted by a profile 19, in the form of a gutter open laterally, composed of two horizontal wings 20, 21 connected by a vertical flank 22. This profile 19 is attached to the internal face 23 of the lower cross member 4 of the frame 3, so that the vertical flank 22 is oriented in the opposite direction to the window 2. In addition, the upper wing 20 is above the horizontal plane 24 passing through the rail of guide 15. Advantageously, the upper wing 20 of this profile 19 has a width 25, greater than the width 26 of the lower wing 21 and determined so as to completely cover said guide rail 15 when the leaf 5 is in the closed position. Because of this particularity of the profile 19, the elements of the mechanism and in particular the operating arm 7 are protected in order to prohibit the user, or any other person, from accessing it during the critical moments of the operation of the opening 5. These critical moments are those when the different moving parts are very close to one another, in particular at the start and at the end, respectively of opening and closing of said opening 5, which considerably increases the risks of jamming d 'a finger or deterioration of the control device 1 due to an object surreptitiously introduced into the mechanism.

Preferably, the profile 19, constituting the protective means 18, extends, substantially, over the entire length of the lower cross member 4 of the frame 3 and covers the housing 6. For this purpose, a cutout 27 is provided in the upper wing 20, in this cutout 27 engaging the boss 10 located on the cover 9 of the housing 6.

This profile 19 can be fixed by screwing, clipping or any other known fixing means on the fixed frame 3. Furthermore, the ends 28, 29 of this profile 19 are closed by flanges 30, 31 attached perpendicularly to the lower cross member. Hour 4. Advantageously, these flanges 30, 31 comprise the means for fixing the profile 19 mentioned above.

In FIG. 2, the shape of the lower cross member 4 of the fixed frame 3 makes it possible to apply the control device 1 directly to the internal face 23. However, it may turn out that this shape of the lower cross member 4 varies, in particular , at the level of the thickness 32 of the internal rim 33. Thus, in FIG. 3, similar to FIG. 2, a lower cross member 4 is shown, the internal rim 33 of which has a particularly reduced thickness 34. Under these conditions, the application of the control device 1 on this infra-hour cross member 4 requires the use of a spacer 35 making it possible to substantially widen the internal rim 33 and bring it to the desired quota.

We refer to figure 4.

The protective means 18, in accordance with the embodiment described above, are not able to cover the operating arm 7 during the entire rotation of the opening 5. To remedy this drawback and according to a second embodiment of the control device 1, the upper wing 20 of the profile 19 is divided into two sections 36, 37, the section 36, located between the front upright 44 of the opening 5 and the boss 10, being removable and fixed, au- above the guide rail 15, on the lower cross member 8 of said opening 5. As a result of this arrangement, said section 36 of the upper wing 20 is capable of covering the operating arm 7 throughout the movement of the opening 5 .

We refer to figure 5.

According to the invention, the control device 1 also includes locking means 38 for locking the opening 5 regardless of the position of the latter. Because of this particular feature of the control device 1, a force applied to the opening 5 is passed on to the locking means 38 and not to the mechanism located in the housing 6.

Preferably, these locking means 38 consist of an arm 39, one end 40 of which is connected by a hinge to the leaf 5,1 ′, the other end 41 of this arm 39 sliding in a locking device 42 integral with the profile 19. Preferably, these locking means 38 are located near the front uprights 43, 44 respectively of the frame 3 and the opening 5.

According to the embodiment shown in Figure 5, the locking device 42 is attached to the upper wing 20 of the profile 19 and consists of a pivoting base 45 provided with a housing 46 serving as a housing for a locking element , such as a barrel or the like, cooperating with the arm 39. It can also be envisaged to insert this locking device 42 into the profile 19 and to attach the pivoting base 45 to the inner face 47 of the upper wing 20. Under these conditions, it is necessary to machine a horizontal groove in the vertical flank 22 of said profile 19, this groove serving for passage at the rear end 41 of the arm 39 during the rotation of the opening 5.

However, this locking device 42 is not able to be fixed on the upper wing 20 when the latter breaks up into two sections 36, 37, the front section 36 being removable and attached to the opening 5. In these conditions, there is a spacer under the pivoting base 45 of this locking device 42 allowing the assembly to rest on the lower wing 21 of the profile 19. In addition, a space is provided between the upper edge 48 of the sidewall vertical 22 and the section 36 of the upper wing 20 serving for the passage at the rear end 41 of the arm 39.
