Definitions

• the present invention relates to the technical field of construction.
• It relates in particular to a complete window and door unit comprising a window frame and a protective assembly.
• protective assemblies for building openings. 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.
• a protective shutter such as a roller shutter curtain
• the fixings must be robust enough to ensure the safety of the protective cover while allowing for easy dismantling if necessary.
• the means of securing allow for rapid installation and, preferably, without specialized tools, thus reducing implementation time and associated costs.
• 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.
• the head may, for example, include at least one wing which is capable of fitting into said longitudinal groove, in assembled configuration.
• a bay block assembly is an assembly comprising a protection assembly 10 and a joinery frame 20.
• the 20 joinery frame is suitable for installation in a building opening (also called a "bay”), possibly to support an opening.
• a building opening also called a "bay”
• 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.
• 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.
• a protective shutter 12 such as a roller shutter curtain or a mosquito net
• the protective shutter 12 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.
• 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.
• 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.
• the lower face of the lower wall 16 is here supported on a high cross member 22, 122 of the frame 20.
• the first end of the lower wall 16 is fixed (here by snap-fit) to a lower end of the side wall 17.
• 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).
• FIG 1 shows the upper crossbar 22 of the joinery frame 20 on which the protection assembly 10 is fixed by means of fastening.
• the upper cross member 22 has an upper face 24 and a lower face 26, connected by two front faces 28, 30.
• first structural profile 32 extends 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.
• 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.
• 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.
• the first structural profile 32 defines a longitudinal recess 38 in the first front face 28.
• 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.
• 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.
• 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.
• 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.
• the joining organ 44 is mobile relative to the receiving structure 42, to define the assembled configuration and the dissociated configuration.
• 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.
• the head 50 here comprises two opposing wings 52, 54, each capable of cooperating with a flap 56, 58 defining one of the longitudinal grooves 46, 48.
• the wing 52, 54 in question is intended to fit into the longitudinal groove 46, 48 in question.
• 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.
• 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).
• FIGS. 2 and 3 are respectively front and top views of the fastening element 44.
• the gripping part 72 is here formed as a single piece with the body 70 and the intermediate part 71.
• the gripping part could be made as a separate piece, mounted (possibly removably) on the body of the fastening member.
• 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).
• the head 50 presents (in section in a plane parallel to the first frontal face 28) a general shape of parallelogram.
• 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.
• the direction of the long edges 76 forms an angle ⁇ ranging from 45° to 90° with the direction of the short edges 78.
• 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.
• This groove 82 extends advantageously along the two short edges 78.
• the head 50 forms two ribs at the short edges 78.
• 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.
• 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).
• 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.
• 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.
• the first 86 reed extends here parallel to a short edge 78 (and in alignment with this short edge 78 in front view).
• 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.
• the breakable tab 84 is supported by the third bead 90.
• 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.
• FIGS. 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.
• the arm forming the gripping part 72 and, here, the first rod 86 extend parallel to the short edges 78. Because the aforementioned angle ⁇ is here less than 80°, the arm forming the gripping part 72 is inclined (here by more than 10°) relative to the vertical.
• 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 .
• the 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.
• 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°.
• the angle ⁇ 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°.
• 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.
• 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.
• 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.
• 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.
• the connecting block 102 is mounted on the lower wall 16.
• 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.
• the connecting block 102 is located opposite (and above) the opening 92 formed in the upper face 24 of the upper cross member 22.
• the fastening element 44 is mounted on the upper cross member 22 in the position shown in the figure 4 .
• the frame 20 and the protective assembly 10 are brought together (by relative vertical movement) until they are in contact the upper face 24 of the upper cross member 22 and the lower face of the lower wall 16 of the chest 14, as shown in figure 7 .
• 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).
• 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.
• the aforementioned horizontal relative movement also allows the retaining tab 108 to be brought into the cavity 96.
• 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.
• 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 .
• This maneuver can be performed by an operator, advantageously without the need for any special tools.
• 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°, that is to say that less than a quarter turn is required.
• each flap 56, 58 engages in the groove 82 formed between the body 70 and the head 50.
• 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 .
• 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.
• 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.
• 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).
• 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).
• the locking member 44 is maneuvered by force so as to break the breakable tab 84.
• This feature helps to prevent unintentional positioning of the fastening element 44 in the assembled configuration.
• 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 ).
• 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).
• 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.
• 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.
• connecting element for assembling a protective unit and a window frame.
• 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.
