In these figures, the identical elements bear the same reference numbers. In these figures, a first element represented in dashed lines is located behind a second element. Figure la shows a schematic perspective view of the flap positioning device 1. The shutter positioning device 1 comprises an angle plate 3 comprising a first face 5 and a second face 7 substantially perpendicular. In the remainder of the description, adjectives and indications such as "up", "down", "horizontal", "vertical" refer to the positioning device 1 as attached to a shutter. The first face 5 has a substantially "U" shape. The first face 5 has fastening means 9 for fixing the positioning device 1 to the flap (not shown). For example, the fastening means 9 comprise a plurality of openings allowing the introduction of a screw (not shown) to screw the positioning device 1 to the flap. The second face 7 comprises a rack of the positioning device 1. For this purpose, a plurality of orifices 11 is located longitudinally along an axis A on the second face 7. The orifices 11 are for example made by punching. The diameter 0 (FIG. 1b) of the orifices 11 makes it possible to insert a hook 13 of standard size, for example the diameter 0 is 9 mm. More specifically, the hook 13 comprises a tip 25 15 folded substantially perpendicular to a rod 16 of the hook 15. The tip 15 is inserted into one of the orifices 11. The rod 16 is generally attached to a wall of a building (not shown ). The orifices 11 are spaced at a distance d, substantially equal to each other (Figure 1c). The positioning of the flap depends on the position of the orifice 11 in which the tip 15 is inserted. Thus the shutter can be more or less ajar. Advantageously, the orifices 11 are at a distance D from the free edge 17 of the second face 7. This makes it possible to improve the securing of the positioning device 1 because the orifices 11 and the tip 15 are spaced from the free edge. 17 and are thus less visible.

The angle plate 3 has a length / (Figure lb), for example 184 mm, a height h, for example 48 mm, a depth p (Figure 1d), for example 24 mm, and a thickness e, for example 2 mm. The positioning device 1 is for example made from steel or aluminum. The positioning device 1 may further comprise a surface treatment, for example made by cataphoresis, or white, yellow or black zinc coating. The surface treatment serves to prolong the life of the positioning device, for example by making it resistant to the weather, for example by improving its resistance to corrosion. The positioning device 1 can also be made of anodized aluminum or powder paint, in this case a wide variety of colors is possible.

The positioning device 1 further comprises a flap 14. The flap 14 has a shape substantially "U" (Figure la). This "U" shape allows a good grip of the flap 14 by a user, the horizontal bar 18 of the "U" serving as a handle of the flap 14. The flap 14 pivots in the side flanges 19, 21 of the device positioning 1. The lateral cheeks 19, 21 extend perpendicularly on either side of the first face 5 towards the second face 7. The lateral cheeks 19, 21 are for example obtained by folding the first face 5. The side cheeks 19, 21 each have an opening 23 cooperating with the joints 25 of the flap. The joints 25 of the flap comprise substantially horizontal projections. The joints 25 each inserted into an opening 23 constitute an axis of rotation of the flap. Thus, the flap 14 pivots in the lateral cheeks 19, 21. In order to insert the tip 15 of the hook into one of the orifices 11, the flap 14 is raised, that is to say, pivoted upwards. Then once the tip 15 is put in place, the flap 14 is folded in a substantially vertical position. The flap 14, in the folded position prevents the extraction of the hook 13, keeping it in place securely in the orifice 11. Indeed, thanks to the flap 14 and folded on the hook 13, it - 7 - is difficult for an intruder outside the building to extract the tip 15 of the hook of the orifice 11. Advantageously, at least one of the side cheeks 19, 21 may comprise a lower stop 27 for good positioning The lower stop is for example obtained by shearing the lateral cheeks 19, 21. The lateral cheeks 19, 21 extend over the entire height h of the first face 5 and their depth p19.21 is substantially equal to the depth p of the angle plate 3 (Figure 1d). Thus, the flap 14 in the folded position is disposed between the lateral cheeks 19, 21. The lateral cheeks 19, 21 enclose lateral openings of the angle plate 3.

This has the advantage of improving the safety of the positioning device 1 by preventing the intruder from raising the flap 14 and extracting the hook 15 by the lateral sides of the angle plate 3. Advantageously, the positioning device 1 can comprise an upper plate 31 (Figure 2a) for closing an upper opening of the angle plate 3. The upper plate 31 has a length / 3 / (Figure 2b) substantially equal to the length / of the angle plate 3, and a depth3 / substantially equal to the depthp of the angle plate 3 (Figure 2c). The upper plate 31 is for example obtained by folding the angle plate 3 perpendicularly. Such an upper plate 31 improves the safety of the positioning device 1, in fact, the intruder can not access either the hook 13 or the flap 14 from above the positioning device 1 (Figure 2c). Advantageously, the face first face 5 may have a spacer 32 (Figure 2d) located substantially in the middle and improving the strength of the upper plate 31.

The upper plate 31 can also serve to limit the pivoting of the flap 14. The positioning device 1 comprising the flap 14 and the side flanges 19, 21 and upper plate 31 thus secures access to the hook 13. The user can leave his shutters open without the risk of the intruder extracting the hook 13 from the angle plate 3. Advantageously, the positioning device 1 may comprise holding means 33 of the flap in the folded position ( Figure 3a). These retaining means in the folded position 33 comprise for example a first elastic element 35. The first elastic element 35 is assembled on at least one of the lateral cheeks 19, 21 at the flap 14. For this purpose, the first elastic element 35 comprises an outer leg 39 (Figure 3b) in contact with an outer face 40 of the side cheek, and an inner leg 41 (Figure 3c) in contact with one side with an inner face 42 of the side cheek and other share with the flap 14 when it is in the folded position. The outer branch 39 and the inner branch 41 are connected by a base 43 in contact with a front end 37 of the side cheek. This first elastic element 35 comprises for example a blade, such as a stainless steel blade. The blade is folded to form the outer branch 39 and the inner leg 41 and the base 43. The first elastic member 35 comprising the folded blade is shown in the free state, that is to say not assembled to the cheek side 19, 21, in Figure 4a. The first elastic member 35 has means for assembling the lateral cheek 19, 21. For example, the assembly means may contain an elastic clip. The clamp comprises the outer branch 39 of the first folded blade as well as the lateral ends 47, 48 of the inner branch 41. The inner branch 41 in fact comprises two lateral ends 47, 48 bordering a median portion 49. The lateral ends 47, 48 and the middle portion 49 are obtained for example by shearing the stainless steel blade. For example (Figure 4b), for a blade width 135 of 10 mm, the middle portion 49 has a width 149 of 6mm. The two lateral ends 47, 48 and the middle part 49 are bent at different angles (FIG. 4c). Thus, in the free state, the lateral ends 47, 48 are folded substantially towards the outer branch 39. The middle portion 49 is folded in a direction substantially opposite to the outer branch 39. When the first elastic member 35 is assembled around of the front end 37 of the side cheek, the outer leg 39 and the lateral ends 47, 48 of the first elastic member 35 deviate to encase the front end 37 of the side cheek. Thus assembled, the lateral ends 47, 48 and the outer arm 39 are substantially parallel. The lateral ends 47, 48 apply a pressure on the lateral cheek 19, 21 in the direction of the outer leg 39. The assembly means of the first elastic member 35 may further contain a non-return protrusion 44. This non-return protrusion 4 is located on the outer branch 39 of the first folded blade. The non-return protuberance 4 is snapped into a hole 45 of the lateral cheek (FIG. 3c). The non-return protrusion 44 is obtained for example by shearing the first folded blade. The hole 45 is obtained for example by punching the lateral cheek 19, 21.

The middle portion 49 of the inner branch is able to deform elastically when the flap 14 is folded. For this, the middle portion 49 is folded accordion along an axis B. Thus, the middle portion 49 has a ridge 51, a recess 53 and a flange 55 adapted to receive and maintain the flap 14 is folded position. The middle portion has a height h49, for example 10 mm.

The recessed arrow 57 indicates the movement of the flap 14 when it is folded down. In order not to hinder the movement of the flap 14, provision is made for clearance 58 (FIG. 3d) located on a vertical bar of the flap, at least in front of the first folded blade. This clearance 58 is for example between 0.5 and 1.0 mm. When the flap 14 is folded down, it first passes over the crest 51 which deforms by flattening. Then, the flap 14 passes over the hollow 53, thus during the passage of the flap 14, the hollow 53 is elastically deformed in the direction of the side cheek 21. The deformation direction of the middle portion 49 is indicated by a full arrow 59. Finally, the flange 55, substantially perpendicular to the inner face 47 of the side cheek, limits the movement of the flap 14. The flap 14 in the folded position is maintained at the level of the hollow 53. Thus the flap 14 is firmly maintained in the folded position which improves the securing of the positioning device 1. The assembly means can not use a bottom stop 27. According to a variant shown in Figure 5, the holding means in folded position 33 include a magnet 61. The magnet 61 is for example fixed on the first face 5 of the angle plate, at the flap 14. A steel piece 63 is fixed on the flap 14 so as to be in touch when the flap 14 is folded down. The steel part 63 comprises for example a steel pellet. Thus arranged, the flap 14 is firmly held in the folded position. According to a variant (not shown), the magnet 61 is fixed on the flap 14 and the steel piece 63 is fixed on the first face 5 of the angle plate.

Advantageously, the positioning device 1 may comprise wear limiting means 65 (FIG. 6a) of the flap 14 and the hook 13. In fact, over time and uses, the pressure exerted by the flap 14 on the hook 13 causes a deterioration of their surface treatment. The wear limiting means 65 comprise for example a second elastic element 67 comprising for example a second stainless steel blade positioned on the horizontal bar 18 of the flap. For this purpose (Figure 6b), the second elastic member 67 comprises an upper wall 69 and a lower wall 71 substantially parallel to each other in the free state, and connected by a side wall 73. The upper wall 69 and the lower wall 71 include edges 74, 75 folded towards each other. When the second elastic element 67 is assembled to the horizontal bar 18 of the flap, the upper wall 69 and the lower wall 71 deviate to enshrine the flap 14. Then, they resume their positions in the free state. The edges 74, 75 are thus folded against the horizontal 18 of the flap and prevent it from coming out. The flap 14 in the folded position is at a distance d from the rod 16 of the hook. The second blade comprises a tab 76 extending towards the rod 16 of the hook inserted into an orifice 11. The tab 76 is for example obtained for example by cutting and folding. When the flap 14 is not yet folded down on the hook, the tab 76 extends over a height greater than the distance d. When the flap 14 is folded down, the tab 76 deforms elastically so that the flap 14 passes over the rod 16 of the hook. The tab 76 fills the distance d between the flap 14 and the rod 16 and exerts pressure on the rod 16 of the hook. Thus, the wear-limiting means 65 make it possible to extend the life of the positioning device 1 without compromising and improving by limiting the play the safety of the user. Alternatively, the wear limiting means 65 comprise a recess 77 located on a lower portion of the horizontal bar 18 of the flap (Figure). The recess is for example between 0.5 to 1.0 mm, which allows a clearance between the flap 14 and the rod 16. Advantageously, the recess 77 is located only on the side (s) right and / or left of the lower part of the horizontal bar 18 and extends over a length / d of the horizontal bar 18. The length / d of the recess is for example 45 mm maximum. Indeed, in order not to compromise the securing of the positioning device 1, the recess 63 is located so that the game is only present when the shutter is fully closed. In addition, this shutter positioning is most frequently performed: generally every night, it is therefore this positioning that causes the most wear of the flap 14 and the hook 13. In the example illustrated by the figure 7, the hook 13 extends from the left of the angle plate 3 and the recess 77 is located on the right of the horizontal bar 18 of the flap. When the flap is fully closed, the hook tip 15 is inserted into the rightmost port 111. When the flap 14 is folded down, the rod 16 of the hook is therefore vis-à-vis the recess 63. The game present between the rod 16 and the flap allows to limit the wear of their surface treatment. When the flap is ajar, the tip 15 is inserted for example into the orifice 112. When the flap 14 is folded down, the rod 16 is not opposite the recess 67. The flap 14 in folded position is in contact with the rod 16 of the hook, which ensures the safety of the user. It is thus clear that a shutter positioning device 1 comprising lateral cheeks 19, 21 closing the lateral openings of the angle plate 3 and thus preventing access to the hook 13 from outside the building makes it possible to improve the safety of the user. In addition, the addition of an upper plate 31 closing the upper opening of the angle plate 3 further improves the safety of the user. Finally, the holding means 33 of the flap in the folded position further improve the safety of the user.
