Description

Title of the invention: Bay block assembly Technical field of the invention

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

[0002] It relates in particular to a bay block assembly comprising a joinery frame and a protection 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, intended to protect windows or doors against various elements or for security reasons.

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

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

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

[0007] The fixings must also be sufficiently robust to ensure the safety of the protective cover while allowing easy dismantling if necessary. Presentation of the invention

[0008] In this context, the present invention proposes a window and door assembly comprising:

[0009] - a window frame, including in particular a top rail, and

[0010] - a protective assembly comprising a box intended to receive a tree training associated with a protective cover, for example a roller shutter curtain,

[0011] which upper cross member of the frame comprises an upper face and a lower face, connected by two front faces, and

[0012] which box comprises a lower wall, opposite the upper face of said upper cross member and which comprises a longitudinal edge defining a descent slot,

[0013] which longitudinal edge is extended, on the side of a lower face of said lower wall, by a drop comprising:

[0014] - a front face for guiding said protective flap, and

[0015] - a rear face opposite one of said front faces of said cross member high,

[0016] which bay block assembly includes fastening means which are provided for fastening said box to said upper cross member,

[0017] characterized in that said fastening means include first fastening means for fastening between said upper cross member and said drop member,

[0018] which first means of securing include at least one mobile securing organ which is maneuverable in relation to a complementary receiving structure between two configurations:

[0019] - an assembled configuration, in which said at least one organ of Solidarisation cooperates with said receiving structure for the solidification of said upper crossbeam with said drop beam, and

[0020] - a dissociated configuration, in which said at least one organ of solidarisation is free with respect to said receiving structure for the decoupling of said upper crossbeam with respect to said drop.

[0021] 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.

[0022] The means of securing allow for rapid installation and, preferably, without specialized tools, thus reducing implementation time and associated costs.

[0023] In assembled configuration, said fastening element ensures a solid and secure attachment of the upper cross member to the drop, minimizing the risks of accidental detachment or undesirable movement.

[0024] According to optional features, which may be combined where feasible:

[0025] - said at least one solidarity body and said receiving structure may be supported by the rear face of the drop and by a front face of the upper crossbar, opposite each other;

[0026] - said at least one securing element may be carried by the front face of the upper cross member, for example by screwing, and said receiving structure can be supported by the rear face of the drop;

[0027] - said at least one fastening element is, for example, rotatable to define the assembled and disassembled configurations;

[0028] - the rear face of the drop and the front face of the upper cross member can define a longitudinal slot opening from 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 dissociated configuration;

[0029] - said at least one solidarity organ may include a part of gripping, monobloc or removable, for example an arm, for its maneuvering between the assembled and disassembled configurations;

[0030] - said gripping part is for example arranged so that, in configuration When dissociated, said gripping part extends through the longitudinal slot and, in assembled configuration, said gripping part is retracted relative to the longitudinal slot;

[0031] - the means of solidarity may further include secondary means of fastenings 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 means of fastening by elastic deformation.

[0032] It can also be foreseen that the first means of securing the connection include:

[0033] - the receiving structure comprising at least one longitudinal groove,

[0034] - said at least one fastening element comprising a head adapted to fit in said longitudinal groove.

[0035] Said at least one locking element can then be maneuvered between two configurations:

[0036] - the assembled configuration, in which said head is locked in said groove longitudinal, and

[0037] - the dissociated configuration, in which said head is unlocked with respect to said longitudinal groove.

[0038] The head may for example include at least one wing which is able to fit into said longitudinal groove, in assembled configuration.

[0039] Said head may comprise:

[0040] - according to one possible embodiment, a single wing, cooperating with a flap defining said longitudinal groove, or

[0041] - according to another possible embodiment, two opposing, cooperating wings respectively with two flaps, each defining a longitudinal groove.

[0042] Of course, the various features, variants, and embodiments of the invention can be combined in various ways, provided they are not incompatible or mutually exclusive. Detailed description of the invention

[0053] [Fig. 10] represents parts of another example of a block bay assembly.

[0054] Generally speaking, a "bay block assembly" is an assembly comprising a protection assembly 10 and a joinery frame 20.

[0055] The joinery frame 20 is adapted to be installed in an opening of a building (also called a "bay"), possibly in order to support an opening.

[0056] The joinery frame 20 is generally equipped with a glazed wall, possibly movable between a closed position (in which the opening closes the opening of the building) and an open position.

[0057] 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.

[0058] Figure [1] shows the elements of such a bay block useful for understanding the invention.

[0059] The protection assembly 10 of the bay block comprises:

[0060] - a drive shaft 11 linked to a protective flap 12, and

[0061] - a box 14 which receives the drive shaft 11 and the protective flap 12 in its retracted position (in which the protective flap 12 is wrapped around the drive shaft 11).

[0062] The theoretical maximum size of the protective flap 12 in its retracted position is shown in dotted lines on [Fig.1].

[0063] By rotating the drive shaft 11 (rotation driven either by an electric motor or by a linkage manually operated 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.

[0064] The box 14 comprises several walls, including a lower wall 16 (also called the "underside"), which together delimit an interior space 13 in which the drive shaft 11 and the protective flap 12 are received in the retracted position.

[0065] In this description, the words "lower", "upper", "horizontal", "vertical" are understood to mean 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.

[0066] As can be seen in [Fig.1], although the box 14 generally has a parallelepiped shape, some of the walls may be inclined to fit the lintel intended to receive the box 14 or for aesthetic reasons.

[0067] The lower wall 16 extends between:

[0068] - a first end located in contact with a first lateral wall 17 (here vertical) of chest 14, for example an access hatch, and

[0069] - a second end forming a longitudinal edge which is extended, on the side of a lower face of the lower wall 16, by a drop 18.

[0070] The lower face of the lower wall 16 is here supported on a high cross member 22, 122 of the frame 20.

[0071] In the example described, the first end of the lower wall 16 is fixed (here by snap-fitting) to a lower end of the side wall 17.

[0072] The lower wall 16 is here essentially formed by:

[0073] - a plate (horizontal in the mounted position), and

[0074] - a separate part mounted at the end of the plate, which forms both the edge longitudinal of the lower wall 16 and the drop 18 extending downwards from this longitudinal edge.

[0075] 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).

[0076] Fig. 1 shows the upper crossbar 22 of the joinery frame 20 on which the protection assembly 10 is fixed by means of fastening means.

[0077] The upper cross member 22 has an upper face 24 and a lower face 26, connected by two front faces 28, 30.

[0078] According to one embodiment, as seen in [Fig. 1], a first structural profile 32, a thermal break profile 34 and a second structural profile 36 extend between a first 28 of said front faces and a second 30 of said front faces (in that order). 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.

[0079] 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.

[0080] 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 transmission between the first structural profile 32 and the second structural profile 36.

[0081] The first structural profile 32 defines a longitudinal recess 38 in the first front face 28.

[0082] The first front face 28 carries (here by screwing within the first structural profile 32) a fastening member 44 which will be described in more detail later.

[0083] As seen in [Fig.1], when the protection assembly 10 is mounted on the frame 20 to form the window unit, the lower wall 16 of the box 14 is located opposite (and here in contact with) 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.

[0084] 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.

[0085] The means for securing the trunk 14 to the upper cross member 22 include:

[0086] - first securing means 40, for securing between the cross member high 22 and the fall 18 and,

[0087] - optionally, second means of solidarity 100 shared between the lower face of the lower wall 16 of the chest 14 and the upper face 24 of the upper cross member 22.

[0088] The first means of solidarity 40 include:

[0089] - at least one securing element 44, carried here by the first frontal face 28 and mobile (here rotating) relative to this first frontal face 28, and

[0090] - a reception structure 42, complementary with respect to the organ of solidarisation 44 and ménagement ici en fra 18 (the receiving structure 42 being supported and / or accessible from the rear face of the fall 18).

[0091] Generally, the first means of securing 40 can include several means of securing 44, for example from 2 to 4. The receiving structure 42 can be linear, extending over the length of the drop 18, or point-like, arranged at the level of the means of securing 44.

[0092] The locking member 44 is maneuverable (here in rotation) relative to this receiving structure 42 between two configurations:

[0093] - an assembled configuration, in which the solidarity organ 44 cooperates with the receiving structure 42 for securing the upper cross member 22 to the drop member 18, and

[0094] - a dissociated configuration, in which the securing organ 44 is free by relation to the receiving structure 42 for the decoupling of the upper cross member 22 from the drop member 18 (this decoupled configuration being used in particular when mounting the protection assembly 10 on the upper cross member 22 as explained below).

[0095] In other words, the joining organ 44 is mobile relative to the receiving structure 42, to define the assembled configuration and the dissociated configuration.

[0096] In the example described, as clearly visible in 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 the assembled configuration.

[0097] 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.

[0098] Thus, when the locking member 44 is in the assembled configuration, the head 50 is locked in at least one longitudinal groove 46, 48 (the two wings 52, 54 being respectively locked in 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.

[0099] In the example described here, as more easily seen in 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).

[0100] The opening 60 leads into a cavity 62 formed within the drop 18, which is shaped like a profile. The cavity 62 is dimensioned to accommodate the head 50 of the joining organ 44 (in the assembled configuration and in the dissociated configuration).

[0101] Cavity 62 includes, in particular:

[0102] - the upper longitudinal groove 46, defined between the upper flap 56, and a wall forming the front face of the drop 18 and

[0103] - the lower longitudinal groove 48, defined between the lower flap 58, and this same wall defining the front face of the drop 18.

[0104] Figures 2 and 3 are respectively front and top views of the fastening member 44.

[0105] As can be clearly seen in these figures, the fastening element 44 comprises:

[0106] - a body 70, which carries the head 50 already mentioned,

[0107] - a grasping part 72 (here an arm) for maneuvering the organ of solidarity 44 between the assembled and dissociated configurations, and

[0108] - an intermediate part 71 connecting the body 70 and the gripping part 72.

[0109] The gripping part 72 is here formed as a single piece with the body 70 and the part intermediate 71. Alternatively, the gripping part could be made as a separate piece, mounted (possibly removably) on the body of the fastening member.

[0110] The head 50 here has a counterbore 74 intended 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).

[0111] In the example described, the head 50 has (in section in a plane parallel to the first front face 28) a general shape of parallelogram.

[0112] Thus, head 50 is delimited by:

[0113] - two first edges 76, here long edges 76 (opposite each other), and

[0114] - two second edges 78, here short edges 78 (opposite each other).

[0115] As can be seen in [Fig.8] shown later, 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 [Fig.8] shown later.

[0116] As can be seen in [Fig.9] shown later, the gap between the short edges 78 is:

[0117] - greater than the gap between the long edges 76;

[0118] - 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.

[0119] Generally, without being limiting and as shown in [Fig.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.

[0120] In the embodiment described here, the direction of the long edges 76 forms an angle a less than 80° (for example between 60° and 80°) with the direction of the short edges 78.

[0121] As can be seen in [Fig.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.

[0122] 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.

[0123] 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 [Fig.9] shown later.

[0124] 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).

[0125] The breakable tab 84 is located (on the intermediate part 72) so as to cooperate with (here to come in support against) an edge of the longitudinal recess 38 formed in the first front face 28 when the securing member 44 is mounted on the upper cross member 22 in its dissociated configuration illustrated on [Fig.4] and described further.

[0126] As explained below, the breakable tongue 84 allows (by cooperation with the edge of the longitudinal recess 38) the securing member 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 further.

[0127] Specifically, the intermediate part 71 here comprises:

[0128] - a first rod 86, which connects the body 70 (at one end of the long edge 76 the closest to the gripping part 72) to the gripping part 72, and

[0129] - a second rod 88 which connects the body 70 (at the other end of the long edge) 76 closest to the gripping part 72) to the gripping part 72.

[0130] The first bead 86 extends here parallel to a short edge 78 (and in alignment with this short edge 78 in front view).

[0131] 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.

[0132] 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 during its operation in assembled configuration.

[0133] Figures 4 and 5 represent the fastening member 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.

[0134] In the dissociated configuration (i.e. for example before assembly of the joinery frame 20 and the protective assembly 10) shown in [Fig. 4], the long edges 76 extend here in a horizontal direction (parallel to the longitudinal axis of the upper rail 22). The gripping portion 72 (as well as here the intermediate portion 71) then extends downwards.

[0135] 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 a is here less than 80°, the arm forming the gripping part 72 is inclined (here by more than 10°) relative to the vertical.

[0136] Furthermore, before the first assembly of the joinery frame 20 and the protective assembly 10, the breakable tongue 84 is in contact with the edge of the longitudinal recess 38 formed in the first front face 28 so as to retain the fastening member 44 in its position illustrated in [Fig.4].

[0137] In order to move the securing member 44 into its position illustrated in [Fig.5], the breakable tab 84 is here broken and detached from the securing member 44 so that the securing member 44 can pivot around the axis of the aforementioned mounting screw to its position illustrated in [Fig.5], where the arm forming part of gripping 72, the short edges 78 and, here, the first bead 86 are horizontal.

[0138] Because the aforementioned angle is less than 80°, the angle of rotation of the locking member 44 from its position illustrated in [Fig.4] to its position illustrated in [Fig.5] is also less than 80°.

[0139] More generally, the angle can be from 45° to 90°. The angle of rotation of the locking member 44 from its position illustrated in [Fig.4], to its position illustrated in [Fig.5], is also from 45° to 90°.

[0140] Furthermore, as already indicated, the means for securing the box 14 with the upper cross member 22 include second rear securing means 100, which are provided between the lower face of the lower wall 16 of the box 14 and the upper face of the upper cross member 22, for example, securing means by elastic deformation.

[0141] These second means of fastening 100 here include a connecting block 102 having a body 104 (or interface) from which extend:

[0142] - elastic legs 106, here from an upper face of the body 104, for its securing with the lower wall 16 of the chest 14, and

[0143] - a retaining tab 108, here from a lateral face of the body 104, for its connection with the upper cross member 22 (for example with the second structural profile 36.

[0144] As can be seen in [Fig.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.

[0145] 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.

[0146] With reference to figures 6 to 9, the assembly method envisaged in this example for assembling the joinery frame 20 and the protection assembly 10 to form the bay block assembly is now described.

[0147] In these figures, for clarity of representation, only the head 50 of the securing organ 44 is shown.

[0148] During a first step represented in [Fig.6], the protective assembly 10 (in particular the lower wall 16 of the box 14 visible in [Fig.6]) and the joinery frame 20 (in particular the upper rail 22) are at a distance from each other.

[0149] 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.

[0150] As can be seen in [Fig.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.

[0151] The securing member 44 is mounted on the upper cross member 22 in its position shown in [Fig.4].

[0152] In a second step, the joinery frame 20 and the protection 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 [Fig.7].

[0153] 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).

[0154] Moreover, in the position shown in [Fig.7], the fastening member 44 is still in its position shown in [Fig.4] relative 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.

[0155] 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 housing 14), until the body 70 of the locking member 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 [Fig. 8]. During this translational movement, the head 50 passes through the opening 60 so as to be located in the cavity 62.

[0156] 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.

[0157] This ensures the desired relative positioning (and temporary fixing) of the joinery frame 20 and the protection assembly 10 (as shown in [Fig.8]), this positioning not yet being locked at this stage by means of the fastening element 44.

[0158] In a fourth step, the joining member 44 is moved (here by rotation) from its position illustrated in [Fig.4], where the joining member is in the dissociated configuration visible in [Fig.8], to its position illustrated in [Fig.5], where the joining member is then in its assembled configuration visible in [Fig.9].

[0159] This maneuver can be carried out by an operator, advantageously without the need for a special tool.

[0160] As already indicated in the description of figures 4 and 5, because the angle defined above is less than 80°, the angle of rotation to go from the dissociated configuration to the assembled configuration is less than 80°, i.e. less than a quarter turn is required.

[0161] 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.

[0162] The groove 82 is configured here to allow guidance of each end of flap 56, 58 (relative to the joining piece 44 and therefore to the upper cross member 22) in the direction of the axis of rotation (here the axis of the mounting screw), so as to position precisely the joining member 44 relative to the drop 18 in the assembled configuration shown in [Fig.9].

[0163] 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.

[0164] As can be seen in [Fig.9], each wing 52, 54 is then housed in the corresponding longitudinal groove 46, 48, which ensures the locking of the fastening member 44 in the receiving structure 42 and thus the maintenance in assembled position of the joinery frame 20 and the protection assembly 10.

[0165] In the positions illustrated in figures 7 and 8, the rear face of the drop 18 and the first front face 28 of the upper cross member 22 are located opposite each other, being substantially parallel to each other.

[0166] 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 member 44 for its operation between the assembled configuration and the dissociated configuration.

[0167] Once in the configuration illustrated in [Fig.9], it is therefore possible, if necessary, to maneuver the securing member 44 from its position shown in [Fig.5] to its position shown in [Fig.4] (where the securing member 44 is in its dissociated configuration), to allow the dismantling of the protection assembly 10 relative to the joinery frame 20.

[0168] 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).

[0169] The gripping part 72 is thus easily accessible before assembly of the protection assembly 10 and the joinery frame 20, then masked when the protection assembly 10 and the joinery frame 20 are assembled (then used mounted in a building opening).

[0170] Generally, during the maneuver towards the assembled configuration, the locking member 44 is maneuvered by force so as to break the breakable tab 84.

[0171] This feature makes it possible to avoid unintentional positioning of the securing element 44 in the assembled configuration.

[0172] Figure 10 presents an alternative embodiment of the embodiment just described. Only the elements differentiating this alternative from the embodiment of Figures 1 to 9 are therefore presented below.

[0173] In this variant, the rear face of the drop 118 comprises a single flap 156 defining a longitudinal groove 146. The head 150 of the fastening member 144 comprises a single wing 152 which cooperates with this flap 156 in the assembled configuration of the fastening member 144 (configuration shown in [Fig. 10]).

[0174] In the variant of [Fig. 10], in the assembled configuration of the fastening member 144, the flap 156 is received between the wing 152 and the first front face 128 of the upper cross member 122 (being in contact with this first front face 128).

[0175] The rear face of the wing 152 (that is to say the face of the wing 152 facing 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.

[0176] The head 150 also includes here a recess 151 allowing the insertion of a tool for the operation of the locking member 144 between its assembled configuration and its dissociated configuration.

[0177] In the preceding description, the use of a fastening element was proposed for the assembly of a protective unit and a window frame. In practice, several such fastening elements can be provided on the top rail to cooperate with corresponding receiving structures provided in the drop of the protective unit.
