[0037] [Fig.6] is a schematic view which illustrates a variant embodiment of the invention, in which the upper rail of the joinery frame is made in one piece with the tenon structure.

[0038] It should be noted that, in these figures, the structural and / or functional elements common to the different variants may have the same references.

[0039] Figure 1 schematically represents an assembly 1 comprising a joinery 2 and a roller shutter box 3.

[0040] The joinery 2 and the roller shutter box 3 are shown here separately from each other and they include special means for their joining or assembly.

[0041] The assembly between the two elements 2 and 3 is carried out before the installation of the assembly 1 in a bay or opening made through a building wall.

[0042] The joinery 2 consists of a door or window structure (illustrated only partially on [Fig.1]) which includes a top rail of the joinery frame 21 having a top face of the top rail 22.

[0043] The upper rail of the joinery frame 21 here comprises two structural profiles 23 and 24, for example made of aluminium, assembled by a thermal break profile 25 made of an insulating material such as PVC or ABS.

[0044] The assembly of the thermal break profile 25 with the two structural profiles 23 and 24 can be carried out in a conventional manner by crimping.

[0045] The thermal break profile 25 constitutes part of the peripheral edge of the frame of the joinery 2.

[0046] The roller shutter box 3 (here partially shown) surrounds a roller shutter curtain (not shown), at least partially and preferably almost entirely.

[0047] In a conventional manner, this roller shutter curtain winds and unwinds around a roller shutter shaft associated with means adapted for its rotational drive.

[0048] The roller shutter box 3 comprises for this purpose a set of longitudinal walls, namely:

[0049] (i) two vertical front walls 31, 32 which extend at a distance and face each other on the other hand, namely - an inner front wall 31 of the chest (or "front wall") intended to be located on the inner side of the building and - an outer front wall 32 of the chest (or "rear wall") intended to be located on the outer side of the building;

[0050] (ii) a lower horizontal wall 33 of the box, commonly referred to as the "underside", which lies below the roller shutter curtain, and which delimits, with the wall front exterior 32, a light 34 for the passage of this roller shutter curtain between its folded / unfolded configurations, and

[0051] (iii) an upper wall of the box, not shown, coming above the added roller shutter curtain, and extending at a distance and opposite the lower wall 33 of the box.

[0052] The roller shutter box 3 is further delimited on the sides by two lateral walls, not shown, consisting of parts called "side cheeks", "flanges" or "end caps".

[0053] The four longitudinal walls and the two lateral sides together delimit the internal volume of the roller shutter box 3.

[0054] The various walls of the roller shutter box 3 here consist of parts made of a thermally insulating thermoplastic material, for example Poly(vinyl chloride) (or PVC). They can be made by an extrusion technique.

[0055] The lower wall 33 of the housing comprises an inner face 331, oriented towards the internal volume of the roller shutter housing, and an outer face 332, oriented outwards. The inner face 331 and the outer face 332 define the thickness of the lower wall 33 of the housing, segmented here into a plurality of longitudinal cells 35.

[0056] In the embodiment shown, this lower wall 33 of the chest is segmented into three rows of cells 35 with:

[0057] - an upper row of alveoli 35 arranged on the side of the inner face 331;

[0058] - a lower row of alveoli arranged on the side of the external face 332, and

[0059] - an intermediate row of cells.

[0060] Because of this honeycomb structure, it is understood that the internal 331 and external 332 faces of the lower wall 33 of the roller shutter box 3 are themselves constituting a thin internal or external wall.

[0061] As specified above, the joinery assembly 2 / roller shutter box 3 includes assembly means 4 adapted for assembling the lower wall 3 of the box with the upper rail of the joinery frame 21 in order in particular to provide it with additional inertia.

[0062] According to the invention, these assembly means 4 consist of at least one tenon structure 5 which extends in projection from one of the elements between the upper face of the upper cross member 22 and the external face of the lower wall of the chest 332, and at least one mortise structure 6, made in a recess in the other element (22 or 332), which tenon structure 5 and which mortise structure 6 are designed to obtain the desired assembly, by penetration of said tenon structure 5 into said mortise structure 6.

[0063] The tenon structure 5 and the mortise structure 6 are designed to be complementary and arranged to achieve the desired assembly.

[0064] The tenon structure 5 and the mortise structure 6 can cooperate by elastic interlocking to secure the assembly.

[0065] In the embodiment illustrated in [Fig.1], the tenon structure 5 is provided on the thermal break profile 25, and the mortise structure 6 is provided in the external face 332 of the lower wall 33 of the roller shutter box.

[0066] More specifically, the tenon structure 5 is made in one piece (or in other words, in one piece) over the entire length of the thermal break profile 25.

[0067] This tenon structure 5 includes a longitudinal hook 51 with an L-shaped cross-section, extending from a base 52, and comprising a hook foot 511 which extends at a right angle by a hook arm 512 whose free end terminates in a locking lip 513.

[0068] For its part, the mortise structure 6 is in the form of a longitudinal groove formed along the entire length of the external face 332 of the lower wall 33 of the chest.

[0069] This mortise structure 6 has a generally L-shaped section and includes an entry opening 61 which extends into a first housing 62, itself extended on one side by a second housing 63 comprising a locking rib 64.

[0070] The second housing 63 forms with the external face 332 of the lower wall 3 a projecting extension 65 whose end carries the locking rib 64.

[0071] As can be seen in particular on [Fig.1], the tenon structure 5 includes a longitudinal sealing joint 66 adapted to complete the sealing with the lower wall 33 of the chest.

[0072] In the illustrated embodiment, this sealing joint 66 is provided on the base 52 of the longitudinal hook 51, and it is intended to cooperate with the external face of the lower wall of the box 332.

[0073] The longitudinal sealing joint 66 can be made in one piece with the thermal break profile, for example by a suitable plastic material co-extrusion technique.

[0074] The assembly between the joinery 2 and the roller shutter box 3 can be carried out before installation on the site, for example at the joiner's who prepares the material before going to the site.

[0075] Initially, as illustrated in [Fig.2], the operator brings the joinery 2 and the roller shutter box 3 close together, with the tenon structure 5 of the joinery 2 positioned opposite the entry opening 61 of the mortise structure 6.

[0076] Next, as can be seen in [Fig.3], the operator drives the longitudinal hook 51 of the joinery 2 into the mortise structure 6, and more particularly into the first housing 62 of the mortise structure 6, by a first translational movement perpendicular to the upper face of the upper cross member 22, and to the external face of the lower wall of the box 332.

[0077] The first housing 62 then receives the hook foot 511 of the longitudinal hook 51, and it is noted on the [Fig.3] that this hook foot 511 then has a possibility of movement in the first housing 62, parallel to the upper face of the upper cross member 22 and to the external face of the lower wall of the box 332.

[0078] The assembly maneuver continues with a second translational movement ([Fig.4]), perpendicular to the first, parallel to the upper face of the upper cross member 22 and to the external face of the lower wall of the chest 332.

[0079] During this second translational movement, the longitudinal hook 51 comes over the protruding projection 65, the hook arm 512 enters the second housing 63 and, at the end of the stroke, the locking rib 64 of said second housing 63 cooperates with the locking lip 513 of the hook arm 512, to obtain the desired assembly, of the type of interlocking assembly.

[0080] The sealing joint 66 provides the seal between the upper rail of the joinery frame 21 and the lower wall 33 of the box.

[0081] It is understood that such an assembly is relatively easy and quick to obtain.

[0082] It does not require any special tools or additional assembly part(s).

[0083] It does not damage the joinery 2 or the roller shutter box 3; and it has excellent sealing characteristics.

[0084] The positioning of the tenon structure 5 on the width of the frame of the joinery 2 and that of the mortise structure 6 on the width of the roller shutter box 3 defines the relative positioning of the roller shutter box 3 and the joinery 2, according to the type of top rail in relation to the lining, and according to the lining itself.

[0085] As illustrated in the attached figures, several mortise structures 6, 6a, 6b, 6c can be provided in the external face 332 of the lower wall 33 of the roller shutter box 3, to provide a choice of relative positioning of the roller shutter box 3 and the joinery 2.

[0086] In this case, in the embodiment illustrated in the figures, the external face 332 of the lower wall 33 of the roller shutter box 3 comprises 4 mortise structures 6, 6a, 6b and 6c.

[0087] The different mortise structures 6, 6a, 6b, 6c are preferably made parallel to each other.

[0088] Preferably also, these mortise structures 6, 6a, 6b, 6c are made along the entire length of the lower wall 33 of the roller shutter box 3.

[0089] Preferably the mortise structure 6, or the mortise structures 6, 6a, 6b, 6c, is / are provided in the lower row of cells 35 which is arranged on the side of the external face 332 of the lower wall 33 of the roller shutter box 3.

[0090] In figures 1 to 4, the assembly between the roller shutter box 3 and the joinery 2 is made using the mortise structure 6 closest to the opening 34 for the passage of the roller shutter curtain.

[0091] Figure 5 shows a different assembly which uses the mortise structure 6b.

[0092] The longitudinal mortise structures 6, 6a, 6b, 6c, made in the external face 332 of the lower wall 33 of the roller shutter box 3, can be provided as through-holes, that is to say with their entry opening 61, from the manufacture.

[0093] In another embodiment, as illustrated in the accompanying figures, during manufacturing, the entry opening 61 of all the mortise structures 6, 6a, 6b, 6c is closed by parts of sealing material 67 constituting a part of the external face 332 of the lower wall 33 of the chest, and the part of sealing material 67 of the mortise structure 6, 6a, 6b, 6c chosen for the assembly means is removed for the implementation of the desired assembly (as illustrated in [Fig.1]).

[0094] This material removal can be carried out by any suitable means. Material weakening, such as thinner lines, can be used to facilitate material removal, and / or a ripping method using a specific machine can be employed.

[0095] In one embodiment, the positioning of the tenon structure 5 and the mortise structure 6 is reversed, i.e. the tenon structure 5 extends from the outer face of the lower wall of the chest 332 and the mortise structure 6 is made in the upper face of the upper cross member 22.

[0096] In yet another embodiment, as illustrated in [Fig.6], the tenon structure 5 is made in one piece (or monobloc) with the upper rail of the joinery frame 21, projecting from its top face 22.

[0097] The joinery frame 2 with its projecting tenon structure 5 can be made of metal (aluminium for example), or of plastic (Poly(vinyl chloride) -PVC) for example.

[0098] In the case where the top rail of the monobloc joinery frame includes the mortise structure, the latter can be made monobloc in the upper face of the top rail.
