Description

Technical field of the invention

[0001] The present invention relates to the technical field of construction.

[0002] It relates in particular to a complete window and door unit comprising a window frame and a protective assembly. State of the art

[0003] The installation of protective assemblies for building openings is well known in the construction industry. These assemblies generally include a protective shutter, such as a roller shutter curtain, designed to protect windows or doors from various elements or for security reasons.

[0004] To facilitate this installation, it has been proposed to provide this protection set within a bay block assembly which also includes a joinery frame to be installed in the opening.

[0005] Several solutions exist for integrating a protective unit onto a window or door frame. These solutions generally use various fixing methods to secure the protective unit's housing to a top rail of the frame.

[0006] However, current fastening methods may require complex installation steps, increasing the associated time and costs.

[0007] Furthermore, the fixings must be robust enough to ensure the safety of the protective cover while allowing for easy dismantling if necessary. Presentation of the invention

[0008] In this context, the present invention proposes a bay unit assembly comprising: a joinery frame, including in particular a top rail, and a protective assembly comprising a box intended to house a drive shaft associated with a protective shutter, for example a roller shutter curtain, which upper rail of the frame comprises an upper face and a lower face, connected by two front faces, and which box comprises a lower wall, opposite the upper face of said upper rail and which comprises a longitudinal edge defining a descent slot, which longitudinal edge is extended, on the side of an inferior face of said lower wall, by a drop comprising: a front face for guiding said protective shutter, and a rear face opposite one of said front faces of said upper rail, which window unit comprises fastening means which are provided for fastening said box with said upper rail, characterized in that said fastening means comprise first fastening means for fastening between said upper rail and said drop, which first fastening means comprise at least one fastening element,mobile, which is maneuverable relative to a receiving structure, complementary, between two configurations: an assembled configuration, in which said at least one fastening element cooperates with said receiving structure for fastening said upper cross member with said drop member, and a dissociated configuration, in which said at least one fastening element is free relative to said receiving structure for unfastening said upper cross member from said drop member.

[0009] Such means of securing rely on the existing structure of the protection assembly and the joinery frame to allow a simple and effective assembly of the box and the upper crossbar.

[0010] The means of securing allow for rapid installation and, preferably, without specialized tools, thus reducing implementation time and associated costs.

[0011] In assembled configuration, said fastening element ensures a solid and secure attachment of the upper crossbar to the drop, minimizing the risks of accidental detachment or undesired movement.

[0012] Depending on optional features, which can be combined where feasible: said at least one fastening element and said receiving structure may be supported by the rear face of the drop and by a front face of the upper cross member, opposite each other; said at least one fastening element may be supported by the front face of the upper cross member, for example by screwing, and said receiving structure may be supported by the rear face of the drop; said at least one fastening element is, for example, rotatable to define the assembled and disassembled configurations; the rear face of the drop and the front face of the upper cross member may define a longitudinal slot opening onto the side of the lower face of the upper cross member, allowing access to said at least one fastening element for its operation between said assembled configuration and said disassembled configuration;said at least one fastening element may include a gripping part, monobloc or removable, for example an arm, for its operation between the assembled and disassembled configurations; said gripping part is, for example, arranged so that, in the disassembled configuration, said gripping part extends through the longitudinal slot and, in the assembled configuration, said gripping part is retracted relative to the longitudinal slot; the fastening means may further include second fastening means which are provided between the lower face of the lower wall of the box and the upper face of the upper cross member, for example, fastening means by elastic deformation.

[0013] It can also be anticipated that the initial means of solidarity will include: the receiving structure comprising at least one longitudinal groove, said at least one securing member comprising a head adapted to fit into said longitudinal groove.

[0014] At least one of the said securing elements can then be maneuvered between two configurations: the assembled configuration, in which said head is locked in said longitudinal groove, and the disassembled configuration, in which said head is unlocked with respect to said longitudinal groove.

[0015] The head may, for example, include at least one wing which is capable of fitting into said longitudinal groove, in assembled configuration.

[0016] The said head may include: According to one embodiment, a single wing, cooperating with a flap defining said longitudinal groove, or according to another embodiment, two opposing wings, cooperating respectively with two flaps each defining a longitudinal groove.

[0017] Of course, the different features, variants and embodiments of the invention can be combined with each other in various ways as long as they are not incompatible or mutually exclusive. Detailed description of the invention

[0018] Furthermore, various other features of the invention become apparent from the attached description made with reference to the drawings which illustrate non-limiting embodiments of the invention and where: [ Fig. 1 ] represents parts of an example bay block assembly useful for understanding the invention; [ Fig. 2] is a front view of an example of a fastening element usable in a bay unit assembly according to the invention; [ Fig. 3 ] is a side view of the solidarity organ of the figure 2 ; Fig. 4 ] represents the fastening element mounted on a top cross member in a first position, corresponding to a dissociated configuration; [ Fig. 5 ] represents the fastening element mounted on the upper cross member in a second position, corresponding to an assembled configuration; Fig. 6 ] represents a first step in an assembly process for the entire bay block of the figure 1 , in which the dormant part and the protective assembly are separated; [ Fig. 7 ] represents a second step in an assembly process for the entire bay block of the figure 1 , in which the chest rests on the upper crossbar of the frame; [ Fig. 8] represents a third step in an assembly process for the entire bay block of the figure 1 , in which the means of solidarity are in a dissociated configuration; Fig. 9 ] represents a fourth step in an assembly process for the entire bay block of the figure 1 , in which the means of solidarity are in an assembled configuration; and [ Fig. 10 ] represents parts of another example of a block bay assembly.

[0019] Generally speaking, we call " bay window assembly » a set comprising a protective set 10 and a joinery frame 20.

[0020] The 20 joinery frame is suitable for installation in a building opening (also called a "bay"), possibly to support an opening.

[0021] The 20 joinery frame is generally equipped with a glazed panel, possibly movable between a closed position (in which the opening closes the building opening) and an open position.

[0022] The protection assembly 10 is designed to position, in a reversible manner, a protective shutter 12 (such as a roller shutter curtain or a mosquito net) opposite the building opening, preferably opposite the glazed wall.

[0023] We have represented on the figure 1 the elements of such a bay block useful for understanding the invention.

[0024] The bay block protection kit 10 includes: a drive shaft 11 linked to a protective cover 12, and a box 14 which receives the drive shaft 11 and the protective cover 12 in its retracted position (in which the protective cover 12 is wrapped around the drive shaft 11).

[0025] We have represented in dotted lines on the figure 1 the maximum theoretical size of the protective flap 12 in its retracted position.

[0026] By rotating the drive shaft 11 (rotation driven either by an electric motor or by a linkage moved manually by a user), the protective shutter 12 can be gradually released outside the box 14, along the slides of the joinery frame 20, until it reaches a deployed position where the protective shutter 12 is positioned opposite the opening of the building.

[0027] The box 14 comprises several walls, including a lower wall 16 (also called the "underside"), which together define an interior space 13 in which the drive shaft 11 and the protective flap 12 are received in the retracted position.

[0028] In this description, the words " lower " superior " horizontal " vertical» are understood in the usual position of use of the joinery frame and the protective assembly, the protective assembly 10 being located above the joinery frame 20 and the protective shutter 12 advantageously extending in a vertical plane in its deployed position.

[0029] As seen on the figure 1 , although the box 14 generally has a parallelepiped shape, some of the walls may be inclined to adapt to the lintel intended to receive the box 14 or for aesthetic reasons.

[0030] The lower wall 16 extends between: a first end located in contact with a first lateral wall 17 (here vertical) of the chest 14, for example an inspection hatch, and a second end forming a longitudinal edge which is extended, on the side of an underside face of the lower wall 16, by a drop 18.

[0031] The lower face of the lower wall 16 is here supported on a high cross member 22, 122 of the frame 20.

[0032] In the example described, the first end of the lower wall 16 is fixed (here by snap-fit) to a lower end of the side wall 17.

[0033] The lower wall 16 is essentially formed here by: a plate (horizontal in mounted position), and a separate piece mounted at the end of the plate, which forms both the longitudinal edge of the lower wall 16 and the drop 18 extending downwards from this longitudinal edge.

[0034] A descent slot 19 allows the protective flap 12 to exit from the interior space 13. This descent slot 19 is formed between the longitudinal edge of the lower wall 16 (in particular its drop 18) and a second lateral wall 15 (which extends parallel to the first lateral wall 17 and opposite it).

[0035] There figure 1 shows the upper crossbar 22 of the joinery frame 20 on which the protection assembly 10 is fixed by means of fastening.

[0036] The upper cross member 22 has an upper face 24 and a lower face 26, connected by two front faces 28, 30.

[0037] According to one embodiment, as seen in the figure 1, extend between a first 28 of said front faces and a second 30 of said front faces (in that order) a first structural profile 32, a thermal break profile 34 and a second structural profile 36. The first structural profile 32, the thermal break profile 34 and the second structural profile 36 together define here the lower face 26 of the upper cross member 22.

[0038] In other words, the first front face 28 is here formed by the first structural profile 32; and the second front face 30 is here formed by the second structural profile 36.

[0039] The upper face 24 and / or the front faces 28, 30 and / or the structural profiles 32, 36 are advantageously made of metal (for example, aluminum). The thermal break profile 34 is advantageously made of plastic material so as to limit heat transfer between the first structural profile 32 and the second structural profile 36.

[0040] The first structural profile 32 defines a longitudinal recess 38 in the first front face 28.

[0041] The first front face 28 carries (here by screwing within the first structural profile 32) a fastening element 44 which will be described in more detail later.

[0042] As seen in figure 1, when the protection assembly 10 is mounted on the joinery frame 20 to form the bay block assembly, the lower wall 16 of the box 14 is located opposite (and here in contact) the upper face 24 of the upper rail 22. Furthermore, a face (called rear) of the drop 18 is then located opposite (and here at a distance) from the first front face 28.

[0043] The front face of the drop 18 (here convex), located opposite this rear face, borders the descent slot 19 and thus allows the guidance of the protective flap 12.

[0044] The means of securing the trunk 14 to the upper cross member 22 include: of the first means of securing 40, for securing between the upper cross member 22 and the drop member 18 and, optionally, of the second means of securing 100 provided between the lower face of the lower wall 16 of the box 14 and the upper face 24 of the upper cross member 22.

[0045] The first means of solidarity include: at least one securing member 44, carried here by the first front face 28 and mobile (here in rotation) relative to this first front face 28, and a receiving structure 42, complementary relative to the securing member 44 and provided here within the drop 18 (the receiving structure 42 being carried and / or accessible by the rear face of the drop 18).

[0046] In general, the first means of securing 40 may include several means of securing 44, for example from 2 to 4. The receiving structure 42 may be linear, extending over the length of the drop 18, or point-like, arranged at the level of the means of securing 44.

[0047] The fastening element 44 is maneuverable (here in rotation) relative to this receiving structure 42 between two configurations: an assembled configuration, in which the fastening member 44 cooperates with the receiving structure 42 for fastening the upper cross member 22 with the drop member 18, and a dissociated configuration, in which the fastening member 44 is free with respect to the receiving structure 42 for dissociating the upper cross member 22 with respect to the drop member 18 (this dissociated configuration being used in particular when mounting the protection assembly 10 on the upper cross member 22 as explained below).

[0048] In other words, the joining organ 44 is mobile relative to the receiving structure 42, to define the assembled configuration and the dissociated configuration.

[0049] In the example described, as clearly visible on the Figures 1 And 9, the receiving structure 42 includes at least one longitudinal groove (here two longitudinal grooves 46, 48); the securing member 44 has a head 50 suitable for fitting into at least one longitudinal groove 46, 48, in assembled configuration.

[0050] For this purpose, the head 50 here comprises two opposing wings 52, 54 capable of cooperating each with a flap 56, 58 defining one of the longitudinal grooves 46, 48. In the assembled configuration, the wing 52, 54 concerned is intended to fit into the longitudinal groove 46, 48 concerned.

[0051] Thus, when the locking member 44 is in the assembled configuration, the head 50 is locked into at least one longitudinal groove 46, 48 (the two wings 52, 54 being respectively locked into the two longitudinal grooves 46, 48 by cooperation with the relevant flap 56, 58). And when the locking member 44 is in the disassembled configuration, the head 50 is unlocked with respect to the aforementioned longitudinal grooves 46, 48.

[0052] In the example described here, as more easily visible on the figures 6 to 9 which will be presented later, an opening 60 is defined in the rear face of the drop 18 to allow the passage of the head 50 when the securing member 44 is in dissociated configuration (this opening 60 extending here between the two flaps 56, 58, here along a general horizontal axis).

[0053] The opening 60 leads into a cavity 62 formed within the drop 18, which is shaped like a profile. The cavity 62 is sized to accommodate the head 50 of the fastening member 44 (in both the assembled and disassembled configurations).

[0054] Cavity 62 includes, in particular: the longitudinal groove 46, upper, defined between the flap 56, upper, and a wall forming the front face of the drop 18 and the longitudinal groove 48, lower, defined between the flap 58, lower, and this same wall defining the front face of the drop 18.

[0055] THE figures 2 and 3 are respectively front and top views of the fastening element 44.

[0056] As clearly visible in these figures, the fastening element 44 comprises: a body 70, which carries the head 50 already mentioned, a grasping part 72 (here an arm) for the operation of the joining organ 44 between the assembled and dissociated configurations, and an intermediate part 71 connecting the body 70 and the grasping part 72.

[0057] The gripping part 72 is here formed as a single piece with the body 70 and the intermediate part 71. Alternatively, the gripping part could be made as a separate piece, mounted (possibly removably) on the body of the fastening member.

[0058] The head 50 here has a counterbore 74 designed to receive a mounting screw for the fastening member 44 on the upper cross member 22 (here on the first front face 28 of the upper cross member 20). This mounting allows the fastening member 44 to rotate between the assembled and disassembled configurations (as already indicated and explained again below).

[0059] In the example described, the head 50 presents (in section in a plane parallel to the first frontal face 28) a general shape of parallelogram.

[0060] Thus, head 50 is delimited by: two first edges 76, here long edges 76 (opposite each other), and two second edges 78, here short edges 78 (opposite each other).

[0061] As seen on the figure 8 As shown further below, the gap between the long edges 76 (corresponding to the length of the short edges 78) is less than the height of the opening 60 (i.e., less than the distance separating the flap 56 and the flap 58) to allow the passage of the head 50 through the opening 60, as shown in the figure 8 presented later.

[0062] As seen on the figure 9 As presented further on, the gap between the short edges 78 is: greater than the gap between the long edges 76; greater than the height of the opening 60 (i.e. greater than the distance separating the flap 56 and the flap 58) to allow the locking of the head 50 in the receiving structure 42, here precisely in the longitudinal grooves 46, 48.

[0063] Generally speaking, without being exhaustive and as represented on the figure 2 , the direction of the long edges 76 forms an angle α ranging from 45° to 90° with the direction of the short edges 78.

[0064] In the embodiment described here, the direction of the long edges 76 forms an angle α less than 80° (for example between 60° and 80°) with the direction of the short edges 78.

[0065] As seen on the figure 3 , the head 50 is connected to the body 70 by a reduced section part 80 which defines a groove 82 extending over at least part of the perimeter of the reduced section part 80.

[0066] This groove 82 extends advantageously along the two short edges 78. In other words, the head 50 forms two ribs at the short edges 78.

[0067] This groove 82 is designed to receive at least one flap (here the two flaps 56, 58) defining the longitudinal groove(s) 46, 48 of the receiving structure 42, as clearly visible on the figure 9 presented later.

[0068] In the described embodiment, the fastening member 44 further includes a breakable tab 84 which extends rearward from the rear face of the intermediate part 71 (here on the side of the first front face 28).

[0069] The breakable tab 84 is located (on the intermediate part 72) so as to cooperate with (here, to be supported against) an edge of the longitudinal recess 38 formed in the first front face 28 when the fastening member 44 is mounted on the upper cross member 22 in its dissociated configuration illustrated on the figure 4 and described further on.

[0070] As explained later, the breakable tongue 84 allows (by cooperation with the edge of the longitudinal recess 38) to immobilize the fastening element 44 relative to the upper rail 22 before assembly of the joinery frame 20 and the protection assembly 10 (to form the bay block assembly), as explained later.

[0071] Specifically, the intermediate section 71 includes the following: a first bead 86, which connects the body 70 (at the level of one end of the long edge 76 closest to the gripping part 72) to the gripping part 72, and a second bead 88 which connects the body 70 (at the level of the other end of the long edge 76 closest to the gripping part 72) to the gripping part 72.

[0072] The first 86 reed extends here parallel to a short edge 78 (and in alignment with this short edge 78 in front view).

[0073] The intermediate part 71 also includes a third bead 90 which connects the first bead 86 and the second bead 88. This third bead 90 extends here parallel to the long edge 76 closest to the gripping part 72. Furthermore, in the embodiment described here, the breakable tab 84 is supported by the third bead 90.

[0074] In general, the gripping part 72 is advantageously parallel to the short edges 78, which here contributes to its masking behind the receiving structure 42 when it is maneuvered in the assembled configuration.

[0075] THE Figures 4 and 5 represent the fastening element 44 mounted on the upper cross member 22, respectively in its position corresponding to its dissociated configuration and in its position corresponding to its assembled configuration.

[0076] In the dissociated configuration (i.e., for example, before assembly of the window frame 20 and the protective assembly 10) shown in figure 4 The long edges 76 extend here in a horizontal direction (parallel to the longitudinal axis of the upper crossbar 22). The gripping part 72 (as well as here the intermediate part 71) then extends downwards.

[0077] In the example described, the arm forming the gripping part 72 and, here, the first rod 86 extend parallel to the short edges 78. Because the aforementioned angle α is here less than 80°, the arm forming the gripping part 72 is inclined (here by more than 10°) relative to the vertical.

[0078] Furthermore, before the initial assembly of the frame 20 and the protective assembly 10, the breakable tongue 84 rests against the edge of the longitudinal recess 38 formed in the first front face 28 so as to retain the fastening element 44 in its position illustrated in the figure 4 .

[0079] In order to be able to move the securing element 44 into its position illustrated on the figure 5The breakable tab 84 is here broken and detached from the fastening member 44 so that the fastening member 44 can pivot around the axis of the aforementioned mounting screw until it reaches its position illustrated on the figure 5 , where the arm forming part of the grip 72, the short edges 78 and, here, the first reed 86 are horizontal.

[0080] Because the aforementioned angle α is less than 80°, the angle of rotation of the fastening member 44 from its position illustrated on the figure 4 to its position illustrated on the figure 5 is also less than 80°.

[0081] More generally, the angle α can be from 45° to 90°. The angle of rotation of the locking member 44 from its position illustrated on the figure 4 , to its position illustrated on the figure 5 , is also from 45° to 90°.

[0082] Furthermore, as already indicated, the means of securing the trunk 14 with the upper cross member 22 include second means of securing 100, rear, which are provided between the lower face of the lower wall 16 of the trunk 14 and the upper face of the upper cross member 22, for example means of securing by elastic deformation.

[0083] These second means of securing 100 include here a connecting block 102 having a body 104 (or interface) from which extend: elastic tabs 106, here from an upper face of the body 104, for its attachment to the lower wall 16 of the chest 14, and a retaining tab 108, here from a lateral face of the body 104, for its attachment to the upper cross member 22 (for example with the second structural profile 36).

[0084] As seen on the figure 6, the connecting block 102 is advantageously located opposite (and above) an opening 92 formed in the upper face 24 of the upper cross member 22.

[0085] This opening 92 leads into a housing 94 formed in the upper part of the upper cross member 22, advantageously a U-shaped housing whose sides are here formed by the first structural profile 32 and the second structural profile 36 and whose bottom is here formed by the thermal break profile 34.

[0086] We now describe, with reference to figures 6 to 9 , the assembly process envisaged in this example for the assembly of the joinery frame 20 and the protection assembly 10 in order to form the bay block assembly.

[0087] In these figures, for clarity of representation, only the head 50 of the securing organ 44 is shown.

[0088] In a first stage represented at the figure 6, the protective assembly 10 (in particular the lower wall 16 of the box 14 visible on the figure 6 ) and the joinery frame 20 (in particular the upper rail 22) are at a distance from each other.

[0089] The connecting block 102 is mounted on the lower wall 16. In this case, the elastic tabs 106 are first inserted through an opening formed in the lower face of the lower wall 16, then expand by elasticity so as to remain in a cavity of the lower wall 16 and thus retain the connecting block 102 against the lower face of the lower wall 16.

[0090] As seen on the figure 6 , the connecting block 102 is located opposite (and above) the opening 92 formed in the upper face 24 of the upper cross member 22.

[0091] The fastening element 44 is mounted on the upper cross member 22 in the position shown in the figure 4 .

[0092] In a second step, the frame 20 and the protective assembly 10 are brought together (by relative vertical movement) until the upper face 24 of the upper rail 22 and the lower face of the lower wall 16 of the box 14 are in contact, as shown in figure 7 .

[0093] During this approach movement, the connecting block 102 passes through the opening 92 formed in the upper face 24 of the upper cross member 22 so as to be located within the housing 94. The retaining tab 108 then extends opposite a cavity 96 formed in the second structural profile 36 (the cavity 96 opening into the housing 94).

[0094] Furthermore, in the position shown in the figure 7 , the solidarity body 44 is still in its position represented in figure 4relative to the upper cross member 22, and the head 50 is now located opposite the opening 60 formed in the rear face of the drop 18.

[0095] In a third step, the frame 20 and the protective assembly 10 are moved relative to each other, here according to a relative horizontal translational movement (during which the upper face 24 of the upper rail 22 remains in contact with the lower face of the lower wall 16 of the casing 14), until the body 70 of the fastening element 44 comes into contact with the rear face of the drop leaf 18 (specifically here in contact with the shutters 56, 58), as shown in the figure 8 During this translational movement, the head 50 passes through the opening 60 so as to be located in the cavity 62.

[0096] The aforementioned horizontal relative movement also allows the retaining tab 108 to be brought into the cavity 96. In this case, the retaining tab 108 is configured to pinch a wall forming the upper face 24 of the upper cross member 22 between the retaining tab 108 and the lower face of the lower wall 16 of the box 14.

[0097] This ensures the desired relative positioning (and temporary fixing) of the frame 20 and the protective assembly 10 (as shown in figure 8 ), however, this positioning is not yet locked in at this stage by means of the solidarity body 44.

[0098] In a fourth step, the securing member 44 is moved (here by rotation) from its position illustrated in figure 4 where the solidarity organ is in a visible dissociated configuration in figure 8 , up to its position illustrated in figure 5, where the solidarity body is then in its assembled configuration visible in figure 9 .

[0099] This maneuver can be performed by an operator, advantageously without the need for any special tools.

[0100] As already mentioned in the description of the Figures 4 and 5 , because the angle α defined above is less than 80°, the angle of rotation to go from the dissociated configuration to the assembled configuration is less than 80°, that is to say that less than a quarter turn is required.

[0101] During this rotation of the locking member 44, the end of each flap 56, 58 engages in the groove 82 formed between the body 70 and the head 50.

[0102] The groove 82 is configured here to allow guidance of each end of the flap 56, 58 (relative to the fastening piece 44 and therefore to the upper crossbar 22) in the direction of the axis of rotation (here the axis of the mounting screw), so as to precisely position the fastening member 44 relative to the drop 18 in the assembled configuration shown in figure 9 .

[0103] In addition, an elastic tension is obtained in the connection between each flap 56, 58 and the corresponding wing 52, 54, so as to ensure a stable position of the fastening member 44 in its assembled configuration.

[0104] As seen on the figure 9, each wing 52, 54 is then housed in the corresponding longitudinal groove 46, 48, which ensures the locking of the fastening element 44 in the receiving structure 42 and thus the maintenance in assembled position of the joinery frame 20 and the protection assembly 10.

[0105] In the positions illustrated on the figures 7 And 8 , the rear face of the drop 18 and the first front face 28 of the upper cross member 22 are situated opposite each other, being substantially parallel to each other.

[0106] The rear face of the drop 18 and the first front face 28 of the upper cross member 22 thus define a longitudinal slot 98 opening onto the side of the lower face 26 of the upper cross member 22, allowing access to the fastening element 44 for its operation between the assembled configuration and the dissociated configuration.

[0107] Once in the configuration illustrated on the figure 9 It is therefore possible, if necessary, to maneuver the locking device 44 from its position shown on the figure 5 to its position shown on the figure 4 (where the securing element 44 is in its dissociated configuration), to allow the dismantling of the protection assembly 10 relative to the joinery frame 20.

[0108] In the example described here, the gripping part 72 is arranged so that, in dissociated configuration, the gripping part 72 extends through the longitudinal slot 98 (for its operation) and, in assembled configuration, the gripping part 72 is retracted relative to the longitudinal slot 98 (because the gripping part 72 then extends behind the drop 18, specifically here between the drop 18 and the first front face 28).

[0109] The gripping part 72 is thus easily accessible before assembly of the protection assembly 10 and the joinery frame 20, then hidden when the protection assembly 10 and the joinery frame 20 are assembled (then used mounted in a building opening).

[0110] In general, during the maneuver towards the assembled configuration, the locking member 44 is maneuvered by force so as to break the breakable tab 84.

[0111] This feature helps to prevent unintentional positioning of the fastening element 44 in the assembled configuration.

[0112] There Figure 10 presents a variant embodiment of the embodiment just described. Only the elements differentiating this variant from the embodiment of figures 1 to 9 are therefore presented below.

[0113] In this variant, the rear face of the drop arm 118 has a single flap 156 defining a longitudinal groove 146. The head 150 of the fastening member 144 has a single wing 152 which cooperates with this flap 156 in the assembled configuration of the fastening member 144 (configuration shown in Figure 10 ).

[0114] In the variant of the Figure 10 , in the assembled configuration of the securing element 144, the flap 156 is received between the wing 152 and the first front face 128 of the upper cross member 122 (being here in contact with this first front face 128).

[0115] The rear face of the wing 152 (that is to say the face of the wing 152 turned towards the first front face 128 of the upper cross member 122) is shaped so as to come into elastic support on the end of the flap 156 when the fastening member 144 is in its assembled configuration in order to allow the fastening member 144 to be maintained in this configuration.

[0116] The head 150 also includes here a recess 151 allowing the insertion of a tool for the operation of the locking device 144 between its assembled configuration and its dissociated configuration.

[0117] In the preceding description, the use of a connecting element was proposed for assembling a protective unit and a window frame. In practice, several such connecting elements can be provided on the top rail to cooperate with corresponding receiving structures provided in the drop of the protective unit.
