Description

CARPENTRY ELEMENT

The present invention relates to a carpentry element intended to receive a bay fill, in particular a part of a frame or sash frame belonging to a bay closure device, such as a door, a window, bay window or the like. The invention also relates to a frame or sash frame comprising such a carpentry element, and to a bay closure device, including a door, a window or the like, comprising such a frame.

In the field of carpentry, it is known to fix a bay fill, in particular glazing, in a receiving frame by positioning the filling against the frame and then immobilizing the filling in the frame with specifically adapted glazing beads. the thickness of the fill and the width of the frame. With this method of attachment, it is necessary, for a given width of frame profiles, to have a set of glazing beads of different widths, where these glazing beads are adapted to variations in the thickness of the fillings that can be mounted in the frame. frame. Under these conditions, joinery manufacturers must produce and store glazing beads of different widths for each frame model, which increases production costs and complicates inventory management. It is these drawbacks that the invention intends to remedy more particularly by proposing a carpentry element, intended to receive a berry filling, which makes it possible to reduce the production costs and to simplify the inventory management for joinery manufacturers. . For this purpose, the subject of the invention is a joiner element intended to receive a bay filler, this element comprising a main section and at least one secondary section which together define at least part of a housing for receiving the filler, characterized in that the joinery element comprises sliding guide members of the secondary profile relative to the main profile in the width direction of the housing.

In the context of the invention, a berry filling can be of any type, in particular a monolithic glass pane or rigid polymer, such as polycarbonate or polymethylmethacrylate; a laminated or multiple glazing unit comprising a plurality of glass or rigid polymer substrates; a sandwich panel comprising a polystyrene foam core and polyvinyl chloride (PVC) siding; a cellular PVC panel. The carpentry element according to the invention makes it possible to modulate the width of the housing for receiving the filling, so that this housing is able to receive fills of different thicknesses. Thanks to the invention, it is sufficient to have a single main profile model and a single profile model (s) secondary (s) to admit different thicknesses of fills, for example a single glazing as well as a double glazing or triple glazing. This limits the number of parts used by a joinery manufacturer, and therefore the number of parts to produce and store. This results in lower production costs and a simplification of inventory management.

Advantageously, the invention makes it possible to modulate the width of the housing for receiving the filling over a range of widths of between approximately 2 mm and 60 mm. Preferably, for a given joinery element according to the invention, the range of variation of the width of the housing for receiving the filling has a span of between approximately 10 mm and 50 mm, more preferably between approximately 20 mm and 48 mm. mm.

According to one aspect of the invention, the sliding guide members comprise a groove of one of the main profile and the secondary profile, in which is received a projecting portion of the other of the main profile and the secondary profile. .

The secondary section is slidably movable relative to the main section, in the width direction of the housing receiving the filling, between a first position corresponding to a minimum width of the housing and a second position corresponding to a maximum width of the housing.

Advantageously, the joinery element comprises covering means adapted to ensure a junction between the main section and the secondary section in each position of the secondary profile between the first position and the second position. Thus, the joinery element is joined in all the positions of the secondary profile between the first position and the second position, which guarantees an aesthetic finish of the carpentry element.

According to one characteristic, the covering means comprise a wall of the main profile and a wall of the secondary profile which are adapted to remain facing each other on at least a portion of their surfaces during sliding of the secondary profile relative to to the main profile between the first position and the second position.

According to one aspect of the invention, the joinery element comprises locking means of the secondary section relative to the main section.

In one embodiment, the locking means comprise complementary detent members of the main section and the secondary profile. Such snap-fasteners offer the possibility of predefining a series of possible widths for the filling receiving housing, corresponding for example to standard thicknesses of fills that can be mounted in the housing. It is possible to provide at least one detent member carried by one of the main profile and the secondary profile, which is able to cooperate with a series of complementary detent members carried by the other one of the main profile and the secondary profile and distributed according to the width direction of the housing. The spacing between the latching members of the series is then adapted to correspond to different desired widths of the housing. By way of example, the detent members may be complementary ribs and recesses. Advantageously, the detent members are carried by facing surfaces of the sliding guide members.

Preferably, the blocking means are configured to ensure a locking of the secondary section relative to the main section in at least two zones which are spaced apart from one another in the width direction of the housing. By way of example, in the case of detents comprising complementary ribs and recesses, two ribs spaced apart from one another in the width direction of the housing are engaged in two recesses equally spaced in the direction width of housing. This arrangement ensures good stability of the secondary profile relative to the main section.

In one embodiment, the locking means are adapted to ensure a reversible blocking of the secondary section relative to the main section. The locking means are then advantageously associated with locking means, for locking the position of the secondary profile relative to the main profile.

The locking means may comprise at least one securing screw between the main section and the secondary section. Such locking with screws is compatible with disassembly of the filling, which is interesting especially in renovation. It is thus possible to replace the filling, for example to go from a single glazing to a double or triple glazing. For this, simply unscrew the locking screw (s) and then deactivate the locking means so as to allow sliding of the secondary section relative to the main section from its original position, corresponding to the thickness of the original filling. The original fill is then removed from the slot and replaced with a new fill. The locking means are then again activated to block a new position of the secondary section relative to the main section, where the width of the housing in the new position is different, in particular greater than the width of the housing in the original position to match the thickness of the new fill. Finally, the new position of the secondary profile is locked with respect to the main section by means of one or more locking screws.

Alternatively, the locking means may comprise a bonding mastic injected into the profiles of the joinery element. In particular, in the case of detent members, the sealant is advantageously injected at the engagement of the detent members. After polymerization, the sealant is intimately connected to the detent members, preventing any movement of the secondary profile relative to the main profile. Of course, such a mastic is not usable in the case where disassembly of the filling is envisaged.

In another embodiment, the locking means are adapted to ensure irreversible locking of the secondary profile relative to the main profile. Such irreversible locking means may be, in particular, in the form of detent members whose cross section promotes mutual engagement during sliding of the secondary section towards the main section, while a force exerted to slide the secondary section away from the main section tends to increase the cooperation between the detent members.

According to one aspect of the invention, the joinery element comprises a single secondary section, inside or outside, slidable relative to the main section. Advantageously, the main profile then forms a first lateral edge of the housing for receiving the filling, intended to come opposite a first main face of the filling, while the secondary profile forms a second lateral edge of the housing, intended to come facing a second main face of the filling opposite to the first main face. The filling is thus sandwiched between the main section and the secondary section, which each bear against the corresponding face of the filling by means of elastically deformable joints, which immobilizes the filling in the housing.

According to another aspect of the invention, the joinery element comprises two secondary profiles each slidable with respect to the main section. Advantageously, the main section is interposed between the two secondary profiles, where one of the secondary profiles is an inner profile while the other secondary profile is an outer profile. A first secondary profile then forms a first lateral edge of the housing for receiving the filling, intended to face a first main face of the filling, while the second secondary profile forms a second lateral edge of the housing, intended to be opposite a second main face of the filling opposite to the first main face. The filling is thus sandwiched between the two secondary profiles, which each bear against the corresponding face of the filling by means of elastically deformable joints, which immobilizes the filling in the housing. In this case, the main section can form at least a portion of the bottom of the housing.

According to an advantageous characteristic, the main section is formed at least in part by a thermal break part.

In the case where the joinery element comprises a single secondary section slidable with respect to the main section, the thermal break part is advantageously interposed between the secondary section and an end portion of the main section, so as to ensure thermal and / or acoustic insulation between them.

In the case where the joinery element comprises two secondary profiles each slidable with respect to the main profile, the thermal break part is advantageously interposed between the two secondary profiles, so as to provide thermal and / or acoustic insulation between the two secondary profiles.

Such insulation is particularly sought when at least one of the profiles flanking the thermal break part is made of a material having a high thermal and / or acoustic conductivity, as is the case in particular for metal profiles, in particular aluminum or steel profiles.

Advantageously, the thermal break member has at least one sliding guide member intended to cooperate with a complementary member of a secondary section.

The thermal break part can be made of any material having good thermal and / or acoustic insulation properties. In particular, the thermal break piece may be based on an organic polymer material. It may be a thermoplastic polymer profile, such as polyvinyl chloride (PVC) or polyamide (PA), in particular shaped by extrusion. Alternatively, it may be a piece of rigid polymeric foam. According to another variant, the thermal break part can be based on mineral fibers, in particular compressed, or pultruded with a resin, for example glass wool or rock.

Each section that frames the thermal break part, whether it be a secondary section or an end portion of the main section, may be made of any material adapted to its function, in particular chosen from the conventional materials in the field of carpentry, especially wood, a metal material such as aluminum or steel, an organic polymer such as PVC. It is understood that the profiles located on either side of the thermal break piece can both consist of the same material, or be made of different materials. In particular, any combination of the materials listed before is possible within the scope of the invention. As non-limiting examples, a carpentry element according to the invention may comprise, on either side of the thermal break part: a wooden section and an aluminum profile; a PVC profile and an aluminum profile; two aluminum profiles; two PVC profiles. The invention also relates to a frame for receiving a rack filler, which comprises at least one carpentry element as described above. This frame may be a fixed frame, in which case the rack filler mounted in the frame is a fixed filler, or a sash frame, in which case the rack filler mounted in the frame is a mobile filler.

Finally, an object of the invention is a bay closure device, such as a door, a window or the like, comprising a frame or sash frame as described above.

When the bay closure device comprises a sash frame according to the invention, it can cooperate with a conventional frame. The or each opening of the device can be rotatably or slidably mounted on the frame. In the closed position, the or each sash frame according to the invention is applied to the frame.

Advantageously, the cooperation between the sash frame according to the invention and the fixed frame is provided between parts of the frames located away from the sliding guide members of the joinery elements of the sash frame. In particular, for each carpentry element of the sash frame, the frame advantageously cooperates with a portion of the main section located away from the sliding guide members, the side opposite the filling. Thus, the cooperation between the sash frame according to the invention and the fixed frame is not influenced by a change of position of the secondary profiles relative to the main profiles of the joinery elements of the sash frame.

In other words, the same frame can cooperate with a sash frame according to the invention regardless of the relative position between the main profiles and the secondary profiles of the joinery elements of the sash frame. In particular, for a given model of sash frame according to the invention, it is possible to change the width of the housing receiving the filling, for example to go from a single glazing to a double or triple glazing, without that influences the cooperation between the sleeping frame and the opening frame. It is therefore not necessary to modify the frame in case of change of the width of the housing of the opening frame according to the invention.

According to one aspect of the invention, it is however also possible to provide a frame allowing an adjustment of the zone of cooperation between the frame and a sash frame according to the invention, depending on the position of the secondary profiles by compared to the main profiles of the joinery elements of the sash frame. For this purpose, each component of the frame advantageously comprises a fixed part and a movable support relative to the fixed part, where the movable support is intended to receive the supporting sash frame, the fixed part and the movable support comprising complementary detent members adapted to ensure a reversible attachment of the movable support on the fixed part. Advantageously, the movable support of each constituent element of the fixed frame receives a seal intended to cooperate, in closed configuration of the bay closure device, with a carpentry element of the sash frame.

According to an advantageous characteristic, the fixed part of each constituent element of the fixed frame comprises a series of latching members distributed in the thickness direction of the fixed frame, where this thickness direction of the fixed frame corresponds, in the closed configuration of bay closure device, to the width direction of the housing receiving the filling of the sash frame. The spacing between the ratchet members is then adapted to correspond to the different thicknesses of the sash frame resulting from the different possible positions of the secondary profiles relative to the main profiles.

The features and advantages of the invention will appear in the following description of four embodiments of joinery elements according to the invention, given solely by way of example and with reference to the appended drawings in which: FIG. 1 is a partial cross-section of a window comprising two door frames consisting of joinery elements according to a first embodiment of the invention and a conventional frame, the secondary profiles of the carpentry elements according to FIG. invention being in a first position relative to the main profiles, wherein the first position corresponds to a minimum width of the filling receiving housing; - Figure 2 is a partial exploded perspective view of an opening frame of the window of Figure 1; - Figure 3 is a view similar to Figure 2 in the assembled configuration of the sash frame, the secondary sections being in the first position relative to the main profiles; - Figure 4 is a section similar to Figure 1, the secondary profiles of the joinery elements according to the invention being in a second position relative to the main profiles, where the second position corresponds to a maximum width of the receiving housing filling ; - Figure 5 is a section similar to Figure 1, wherein the sash frames consist of joinery elements according to a second embodiment of the invention, the secondary profiles are in a first position with respect to main profiles, corresponding to a minimum width of the filling receiving housing; - Figure 6 is a section similar to Figure 5, the secondary profiles of the joinery elements according to the invention being in a second position relative to the main profiles, corresponding to a maximum width of the filling receiving housing; - Figure 7 is a section similar to Figure 1, in which the sash frames consist of joinery elements according to a third embodiment of the invention, the secondary sections are in a first position relative to the main profiles, corresponding to a minimum width of the filling receiving housing; - Figure 8 is a section similar to Figure 7, the secondary profiles of the joinery elements according to the invention being in a second position relative to the main profiles, corresponding to a maximum width of the filling receiving housing; FIG. 9 is a section similar to FIG. 1 for a window comprising two door frames made up of joinery elements according to a fourth embodiment of the invention and an adjustable frame, the secondary sections of the elements of joinery constituting the sash frames being in a first position relative to the main profiles, corresponding to a minimum width of the housing receiving filler, and the fixed frame being adjusted to this first configuration of the sash frames; and - Figure 10 is a section similar to Figure 8, the secondary profiles of the joinery elements according to the invention being in a second position relative to the main profiles, corresponding to a maximum width of the receiving housing filling, and the dormant frame being adjusted to this second configuration of the sash frames.

In the first embodiment shown in Figure 1, the window 9 is a window with two leaves, comprising a main opening 94 and a secondary opening 96 which are held on a frame 97 by hinges (not shown) . Conventionally, the fixed frame 97 is provided to be secured to a supporting structure, in particular a wall or a partition of a building. The opening 94 and 96 each comprise an opening frame, 93 or 95, and a filling. In FIG. 1, the filling 91 is for example a double glazing having a thickness ei of 28 mm.

The frame 93 of the main opening 94 is formed by the assembly of four joinery elements 1 according to the invention, which all have the same cross section. Two carpentry elements 1 of the frame 93 are visible in Figure 1, where one is provided to cooperate with an element 6 of the fixed frame 97, while the other forms a first portion of the central mass 98 of the window.

The frame 95 of the secondary opening 96 is also formed by the assembly of four joinery elements 1 according to the invention, comprising three carpentry elements which have the same cross section as the frame 93 of the carpentry elements, and one fourth carpentry element, visible in Figure 1, which forms a second portion of the central mass 98 of the window. This fourth element of carpentry has a cross section slightly modified compared to that of other joinery elements, which is adapted to cooperate with the first part of the central mass 98.

In practice, this fourth element of carpentry differs from other carpentry elements only by the shape of its end portion 2 and by the presence of a battue 15, fixed on a secondary section 4 of the element by screwing to the 16. The beater 15 is provided to close the central mass 98 bearing, by means of seals 17 and 18, respectively against a secondary section 4 of the element 1 of the frame 93 forming the first part. of the central mass 98 and against the secondary section 4 of the element 1 of the frame 95 forming the second part of the central mass 98.

In the following, a carpentry element 1 of the frame 93 is described in detail, it being understood that this description is valid for each element of joinery 1 of the window.

As clearly visible in the perspective views of FIGS. 2 and 3, each joinery element 1 comprises on the one hand a main section, which is formed by the combination of an inner end part 2 and a part of thermal break 3, and secondly an external secondary section 4. The thermal break 3 is secured to the end portion 2 by screwing with screws 11. As an example not in this embodiment, the end portion 2 is a wooden section; the thermal break piece 3 is a PVC profile; the secondary section 4 is an aluminum profile.

The main profile and the secondary profile together define a housing 5 for receiving a filling, in particular the filling 91 in FIG. 1. X is denoted by the direction which is parallel to the width dimension of the housing 5. In accordance with FIG. In the invention, the main profile and the secondary profile are slidable relative to each other in the X direction, so that the width of the housing 5 can be modulated to accommodate different thicknesses of fills.

The end portion 2 and the secondary section 4 each form a lateral edge of the housing 5, the bottom of the housing 5 being formed by successive walls of the end portion 2, the thermal bridge break piece 3 and the secondary profile 4. In the configuration of Figure 1, the side edge of the housing 5 formed by the end portion 2 abuts against a face 91A of the filling 91, via a seal 12 housed in a cavity 25 of part 2, and the side edge formed by the secondary section 4 abuts against a face 91B of the filling 91 opposite the face 91 A, via a seal 13 housed in a cavity 45 of the section 4 The filling 91 is thus immobilized in the housing 5.

The relative sliding of the main section and the secondary profile in the X direction is guided by cooperation between a groove 32 of the thermal bridge breaker piece 3 and a projecting portion 42 of the secondary profile 4. More specifically, the projecting portion 42 is received in the groove 32 and is slidable therein, in the X direction, between a first position shown in Figure 1, which corresponds to a minimum width li of the housing 5, and a second position shown in the figure 4, which corresponds to a maximum width 12 of the housing 5. The width of the housing 5 and the thickness of the seals 12 and 13 determine the filling thickness that can be fixed in the housing 5. For example, the minimum width li of the housing 5 can accommodate a thickness of filling ei if using 12 and 13 standard thickness seals, but it is also possible to fix fills thick inf higher to ei in the housing 5 of li width when using the seals 12 and 13 thicker.

On the opposite side to the housing 5, the element 1 comprises two walls 37 and 47, respectively belonging to the thermal bridge break piece 3 and the secondary section 4, which are configured to remain facing each other during sliding of the secondary section 4 between the first position and the second position. In the first position visible in FIG. 1, the walls 37 and 47 are in mutual overlap on substantially all of their surfaces, while in the second position visible in FIG. 4, the walls 37 and 47 are in continuity with each other. one from the other, with a limited overlap of their surfaces. The side 1B of the joinery element 1 opposite the housing 5 is thus closed in all the positions of the secondary section 4 between the first position and the second position, which ensures a good visual appearance of the element 1, whatever the position of the secondary section 4. Advantageously, the sliding guide members 32 and 42 are housed in the inner volume of the element 1, which is closed on the side 1 B.

In order to ensure blocking in position of the secondary section 4 with respect to the thermal break piece 3, the joinery element 1 comprises complementary latching members. More specifically, the groove 32 of the thermal bridge breaker piece 3 is provided on an inner face 33 with a series of recesses 35 distributed in direction X, seven in number in the example shown, while the part protruding 42 of the secondary section 4 has two ribs 44 and 46 on its face 43 which is positioned facing the face 33 when the portion 42 is received in the groove 32. The ribs 44 and 46 are configured to engage simultaneously in two recesses 35, and thus block in position the secondary section 4 relative to the thermal break piece 3. The engagement of the ribs 44 and 46 in two recesses 35 which are spaced from each other according to the direction X makes it possible to ensure good stability of the secondary section 4 with respect to the thermal bridge break piece 3.

It is possible, by engaging the ribs 44 and 46 in two recesses 35, to define five positions of the secondary section 4, corresponding to five different values of the width of the housing 5. These five positions comprise the first position corresponding to the width minimum i of the housing 5, the second position corresponding to the maximum width 12 of the housing 5, and three intermediate positions corresponding to three widths of the housing 5 between li and 12. Advantageously, the spacing between the recesses 35 can be adjusted to correspond to widths of the housing 5 to accommodate fills of standard thicknesses such as, by way of non-limiting examples, 28 mm thick glazings , 30 mm, 32 mm, 34 mm, 36 mm.

In this embodiment, the profiles of the ribs 44, 46 and recesses 35 are chosen such that their engagement is reversible. Thus, the secondary section 4 can pass from one position to another by disengagement of the snap, then by sliding of the secondary section 4 relative to the thermal break part 3 according to the X direction to put the ribs 44 and 46 opposite other recesses 35, and by engaging the ribs 44 and 46 with these new recesses 35.

The locking of the secondary section 4 in one of the five positions is obtained by screwing, using screws 14 which secure the thermal break part 3 with the secondary section 4 by passing through the groove 32 and the part protruding 42. Advantageously, the locking with the screws 14 is also reversible. Each screw 14 is indeed accessible by disassembly of a headrest 31 of the thermal bridge breaker 3.

FIG. 4 shows the window 9 while the joinery elements 1 have their secondary profiles 4 locked in the second position, corresponding to the maximum width 12 of the housing 5. This maximum width 12 allows to accommodate in the housing 5 a filling 92 , which is for example a triple glazing having a thickness e2 of 36 mm, greater than the thickness ei of the filling 91.

As is apparent from this first embodiment, the invention allows, from a single model of joinery elements 1, to produce windows having fills of different thicknesses. Thus, thanks to the invention, a joinery manufacturer has only one model of joinery elements 1 to produce and store, while also being able to offer a range of windows with fillings of various thicknesses. The invention also provides windows whose filling can be replaced, especially in the context of a renovation, for example to go from a single glazing to double glazing or triple glazing. For this purpose, the locking screws 14 of each of the joinery elements 1 of the window are unscrewed and then, for each joinery element 1, the ribs 44 and 46 are disengaged with respect to the recesses 35, and are slid the secondary section 4 away from the thermal break piece 3, possibly to release the secondary section 4 relative to the rest of the joinery element 1 as shown in Figure 2. The filling is then extracted original out of the housing 5 of the elements 1 and is positioned a new filling in these housing. The projecting part 42 of the secondary section 4 of each element 1 is then reengaged in the guide groove 32 of the thermal bridge break piece 3 of the joinery element, and the ribs 44 and 46 are engaged in new recesses 35 to block a new position of the secondary section 4. This new position is chosen to correspond to a width of the housing 5 to immobilize the new filling between the joints 12 and 13. Finally, for each element of joinery 1, the new position of the secondary section 4 is locked by means of the locking screws 14.

In the example shown, the fixed frame 97 of the window 9 is formed by four elements 6 which each comprise an upright 7 and a cover 8. The cover 8 of each element 6 of the fixed frame comprises a support 81 for receiving a seal 19, where the seal 19 is intended to cooperate with a carpentry element 1 of the corresponding sash frame 93 or 95, to ensure a good connection between the frame 97 and the sash frame 93 or 95 in configuration closed from the window. By way of non-limiting example, in this embodiment, each upright 7 is a wooden section and each cover 8 is an aluminum cover.

As clearly visible in FIGS. 1 and 4, the cooperation between the fixed frame 97 and the sash frame 93 or 95 is provided between, on the one hand, the support 81 via the seal 19 and, on the other hand, a part 39 of the thermal break part 3 which is located on the side 1B of the joinery element 1, outside the volume closed by the walls 37, 47 in which are housed the sliding guide members 32, 42. Thus, the cooperation between the fixed frame 97 and the opening frame 93 or 95 is not influenced by a change of position of the secondary profiles 4 between the first position and the second position, as is well illustrated by a Comparison of Figures 1 and 4. An advantage of this first embodiment is that the same frame 97 can be used for all the positions of the secondary sections 4 of the opening frame 93 or 95.

In the second embodiment shown in FIGS. 5 and 6, the elements similar to those of the first embodiment bear identical references increased by 100. In this second embodiment, each element of joinery 101 comprises on the one hand a main section, which is formed by the combination of an inner end portion 102, a thermal break piece 103 and an outer cover 104, and an inner secondary section 120 on the other hand. thermal bridge break piece 103 is secured to the end portion 102 by screwing, and the cap 104 is secured by snapping on the thermal bridge breaker 103. The secondary section 120 has a covering 121 and a body 123 bearing a seal 112. By way of non-limiting example, the end portion 102 is a wooden section; the thermal break piece 103 is a PVC profile; the cover 104 is an aluminum profile; the secondary profile 120 comprises a wooden cladding 121 and a body 123 made of PVC.

The main section and the secondary profile together define a housing 105 for receiving a filling. The secondary section 120 and the cover 104 each form a lateral edge of the housing 105, the bottom of the housing 105 being formed by successive walls of the body 123, the thermal bridge breaker 103 and the cover 104. The main profile and the secondary profile are slidable relative to each other, in the width X direction of the housing 105, so that the width of the housing 105 can be modulated to accept different thicknesses of fills.

The relative sliding of the main section and the secondary profile in the X direction is guided by cooperation between a groove 134 of the thermal bridge breaker piece 103 and a projecting portion 122 of the body 123 of the secondary section 120. More specifically, the part projection 122 is received in the groove 134 and is slidable therein, in the X direction, between a first position shown in Figure 5, which corresponds to a minimum width li of the housing 105, and a second position shown. in FIG. 6, which corresponds to a maximum width 12 of the housing 105. As previously, the width of the housing 105 and the thickness of the seals 112 and 113 determine the filling thickness that can be fixed in the housing 105. 101B side of the joinery element 101 opposite the housing 105 is closed in all positions of the secondary section 120 between the first and second positions, which guaranteed t a good visual appearance of element 101.

In order to ensure a blocking in position of the secondary section 120 with respect to the thermal bridge breaking part 103, the groove 132 of the thermal bridge breaking part 103 is provided with a series of recesses 136 distributed according to the direction X, while the projecting portion 122 of the secondary section 120 has two ribs 124 and 126 configured to engage simultaneously in two recesses 136. Advantageously, the spacing between the recesses 136 is adjusted to correspond to widths of the housing 105 to accommodate fills of standard thicknesses such as, by way of non-limiting examples, glazing thicknesses 24 mm, 28 mm, 30 mm, 32 mm, 34 mm, 36 mm. For example, the filling 191 shown in Figure 5 is a double glazing thickness ei = 24 mm, while the filling 192 shown in Figure 6 is triple glazing thickness e2 = 36 mm.

Optionally, the position of the secondary section 120 relative to the main section can be locked by screwing, using screws (not shown) which secure the thermal bridge break piece 103 with the secondary section 120 passing through the groove 134 and the projecting portion 122.

In the third embodiment shown in FIGS. 7 and 8, elements similar to those of the first embodiment carry identical references increased by 200. This third embodiment differs from the two previous embodiments in that each element of FIG. Joinery 201 comprises two secondary profiles located on either side of a main section. The main profile is formed by the combination of an inner end portion 202 and a thermal break piece 203, where the thermal break piece 203 is secured to the end portion 202 by screwing. . The joiner element 201 comprises, in addition to the main profile, an outer secondary section 204 similar to the secondary section 4 of the first embodiment and an inner secondary section 220 similar to the secondary section 120 of the second embodiment. By way of non-limiting example, the end portion 202 is a wooden section; the thermal break piece 203 is a PVC profile; the outer secondary section 204 is an aluminum profile; the inner secondary section 220 comprises a wooden covering 221 and a body 223 made of PVC.

The main profile and the two secondary profiles together define a housing 205 for receiving a filling, each secondary section 204 or 220 being able to slide relative to the main section, in the X direction of width of the housing 205, so that the width of the housing 205 can be modulated to accept different thicknesses of fills. The outer secondary section 204 and the inner secondary section 220 each form a lateral edge of the housing 205, the bottom of the housing 205 being formed by successive walls of the body 223, the thermal bridge breaker 203 and the outer secondary section 204. .

The relative sliding of the main section and the outer secondary section 204 in the X direction is guided by cooperation between a groove 232 of the thermal bridge breaker 203 and a projecting portion 242 of the outer secondary section 204. Similarly, the sliding relative of the main section and the inner secondary section 220 in the X direction is guided by cooperation between a groove 234 of the thermal bridge breaker 203 and a projecting portion 222 of the body 223 of the inner secondary section 220. Thus, the parts protruding 242 and 222 are each received in the corresponding groove 232 or 234 and are slidable in the X direction, between a first position of each projecting portion shown in Figure 7, which corresponds to a minimum width li of the housing 205 and a second position of each protruding portion shown in Fig. 8, which corresponds to a maximum width 12 of the housing 205. As before, the width of the housing 205 and the thickness of the seals 212 and 213 determine the filling thickness that can be fixed in the housing 205. The side 201B of the joiner element 201 opposite the housing 205 is closed in all the positions of the secondary profiles 204 and 220 between the first and second positions, which guarantees a good visual appearance of the element 201.

For the locking in position of each secondary section 204 or 220 with respect to the thermal bridge breaker 203, each groove 232 or 234 of the thermal bridge breaker 203 is provided with a series of recesses 235 or 236 distributed in the X direction, while the projecting portion 242 or 222 of the secondary section 204 or 220 has two ribs 244, 246 or 224, 226 configured to engage simultaneously in two recesses. Advantageously, the spacing between the recesses 235 and 236 is adjusted to correspond to widths of the housing 205 to accommodate fills of standard thicknesses such as, by way of non-limiting examples, glazing thicknesses 24 mm, 28 mm, 30 mm, 32 mm, 34 mm, 36 mm, 44 mm. For example, the filling 291 shown in Figure 7 is a double glazing thickness ei = 24 mm, while the filling 292 shown in Figure 8 is a triple glazing thickness e2 = 44 mm.

The locking in position of the outer secondary section 204 relative to the main section is obtained by screwing, using screws 214 which secure the thermal break part 203 with the outer secondary section 204 by passing through the groove 232 and the projecting portion 242. Optionally, the position of the inner secondary section 220 relative to the main section can also be locked by screwing, using screws (not shown) which secure the thermal bridge break piece 203 with the inner secondary section 220 passing through the groove 234 and the projecting portion 222.

In the fourth embodiment shown in FIGS. 9 and 10, elements similar to those of the first embodiment carry identical references increased by 300. This fourth embodiment differs from the third embodiment in that the frame structure Sleeper 397 has been modified to allow adjustment of the zone of cooperation between the sash and the frame, according to the configuration of the joinery elements 301 of the sash frames 393 and 395. More specifically, each element 306 of the sleeping frame 397 comprises not only an amount 307 and a cover 308 attached to the upright, but also a movable support 381 provided to receive a seal 319 which is intended to cooperate, in the closed configuration of the window 309, with a 301 carpentry element of the frame opening 393 or 395 corresponding. The cover 308 and the mobile support 381 comprise complementary detent members in the form of hooks 385 of the cover 308 adapted to engage with complementary hooks 387 of the mobile support 381. Thus, the movable support 381 is adapted to be reversibly fixed on the cover 308, and its position relative to the sash frame 393 or 395 can be adjusted depending on the position of the secondary profiles 304, 320 relative to the main section 302, 303 of each 301 woodworking element of the opening frame.

Advantageously, the cover 308 comprises a series of hooks 385, three in number in the example shown, which are distributed in the thickness direction of the fixed frame, which corresponds, in the closed configuration of the window 309, to the X direction of width of the housing 305. The spacing between the hooks 385 is adapted to correspond to different thicknesses of sash frame, in particular to the different thicknesses of the sash frame 393, 395 resulting from the possible positions of the secondary profiles 304, 320 relative to the main profile 302, 303 of each joinery element 301. Preferably, the movable support 381 comprises at least two hooks 387 configured to engage simultaneously with at least two hooks 385. The engagement of at least two 387 hooks with at least two hooks 385 which are spaced from each other in the thickness direction of the sleeping frame ensures a good stability of the movable support 381 with respect to the cover 308. The invention is not limited to the embodiments described and shown. In particular, the invention is not limited to the structures of guiding members and locking members described above, the guiding of the sliding of the or each secondary section and the blocking of the position of the or each secondary profile being able to be assured by all appropriate means. Furthermore, the invention has been illustrated in the case of a window with two leaves rotatably mounted on a frame. A carpentry element according to the invention is, however, usable as a constituent element of a sash frame belonging to any type of closure device, door-type, window or the like, the closure device may or may not have a central mass, the opening of the closure device can be rotatably or slidably mounted on the frame. A carpentry element according to the invention can also be used as a component of a frame, in which case the filling mounted in the frame is a fixed filling, for example for a fixed window or a canopy.
