Description

Title of the invention: GLAZED OPENING FOR JOINERY, JOINERY COMPRISING SUCH AN OPENING, AND METHOD FOR MANUFACTURED BY SUCH AN OPENING 1. Scope of the proposed technology

[0001] The field of the proposed technology is that of the building, and, more specifically, of joinery intended to equip the bays of a building.

[0002] More specifically, the proposed technique relates to glazed openings of such joinery.

[0003] Such glazed openings have numerous applications, particularly for glazed joinery such as sliding or casement doors or windows. 2. Prior art

[0004] Joinery, whether doors or windows, generally includes a fixed frame receiving one or more opening parts and, where applicable, one or more fixed panels.

[0005] To date, we can distinguish two main types of glazed openings, namely: glazing bead openings and bi-fold openings.

[0006] A glazing beaded opening comprises a frame, one side of which has a projection called a rebate. Glazing is fitted into the frame so that one edge of the glazing rests in the rebate. A glazing bead is then fitted to the opposite side of the frame to secure the glazing in position within the frame. In other words, the glazing bead applies a clamping force to the edge of the glazing.

[0007] This approach requires the use of a relatively thick frame to ensure the glazing bead is fixed. These significant dimensions are necessary, in particular, to provide the frame with sufficient rigidity, especially for the design of a large opening, i.e., an opening fitted with large glazing.

[0008] This approach, however, has drawbacks. Indeed, the large dimensions of the frame make it particularly visible. Besides sometimes being considered unsightly, such a massive frame limits the glazing area of ​​the opening. This results in a reduction of light in the room where the window is installed. Furthermore, the clamping force exerted by the glazing bead on the glass may prove insufficient to ensure effective retention of the glazing, especially large panes.

[0009] A hinged opening includes a glazing mounted in a frame of which at least one edge, or side, has a rebate formed by two rebate cheeks overlapping an edge of the glazing.

[0010] The frame is generally made from profiles to form a rebate having two lateral cheeks, and receiving the edge of the glazing.

[0011] This approach requires the implementation of a seal on the edge of the glazing to ensure its retention in the rebate. More specifically, the sealing gasket has a substantially U-shaped cross-section, so as to surround the edge of the glazing, each arm of which may carry snap-on means. These snap-on means are configured to cooperate with complementary means provided on the first ends of the rebate cheeks, when the glazing is inserted between the rebate cheeks.

[0012] This approach also has drawbacks. The clamping force exerted by the snap-fit ​​means on the edge of the glazing is essentially localized. Consequently, under wind load, the frame is likely to pivot relative to the glazing, which can cause the glazing to shrink. This phenomenon is particularly noticeable when installing large panes of glass. The snap-fit ​​means therefore do not ensure effective retention of the glazing within the frame. Furthermore, inserting the glazing between the rebate cheeks causes deformation of the gasket at the corners of the glazing, which detracts from the aesthetics of the opening and compromises its weatherproofing. Finally, after the glazing is assembled onto the frame, a portion of the snap-fit ​​means remains visible. This portion of the gasket, commonly called flashing, also detracts from the aesthetics and the clear area of ​​the glazing in the opening.

[0013] Another disadvantage is that the thickness of the glazing can vary slightly, by a few tenths of a millimeter, and that the installation and maintenance of the seal can be difficult or insufficiently effective.

[0014] There is therefore a need to provide a glazed opening technique which does not present all or part of the disadvantages of current solutions. 3. Summary of the proposed technique

[0015] The proposed technique relates, according to a first aspect, to a joinery opening of the type door or window comprising a glazing mounted in a frame of which at least one side is formed by a body having two cheeks of which first parts, called rebate cheeks, overlap an edge of the glazing.

[0016] According to the invention, the body is deformable such that second portions of the cheeks, called groove cheeks, can be brought closer together under the effect of an external stress so as to move the rebate cheeks further apart to allow the glazing to be installed in the body. Furthermore, the rebate cheeks and groove resume a holding position in the absence of stress, in which the glazing is held between the rebate cheeks.

[0017] Such an opening further includes means for locking the groove cheeks in the holding position.

[0018] Such a sash structure makes it possible, in particular, to improve the glazing's pull-out resistance to the frame, without the need for adhesive. This simplifies installation and allows for a reduction in the dimensions of the rebate cheeks, resulting in a more discreet frame and a larger glazed area. It also allows for the efficient and simple management of a glazing thickness tolerance of several tenths of a millimeter.

[0019] According to a particular feature of the proposed technique, the locking means comprise at least one locking key, a locking portion of which extends between the groove cheeks.

[0020] Such a locking key makes it possible in particular to effectively lock the rebates, while allowing, by removing this key, the dismantling or maintenance of the opening (for example to replace the glazing).

[0021] According to another particular feature of the proposed technique, the body carries at least one thermal break extending substantially parallel to the locking portion of the locking key.

[0022] According to another particular feature of the proposed technique, the thermal break has a deformable structure capable of adapting to different thicknesses of glazing.

[0023] According to another particular feature of the proposed technique, the blocking portion has at least one blocking end of a shape complementary to a blocking structure provided on the groove cheeks.

[0024] Thus, the assembly of the locking key is simple and efficient, and reversible.

[0025] According to another particular feature of the proposed technique, the locking key extends over at least 90% of the body length.

[0026] According to another particular feature of the proposed technique, the opening includes at least two locking keys distributed in the body.

[0027] For example, the locking means include several locking keys distributed at regular intervals, for example every 5 or 10 cm, along the body.

[0028] According to another particular feature of the proposed technique, the locking keys are made of metal, PVC or a suitable synthetic material.

[0029] According to another particular feature of the proposed technique, at least one of the locking keys has a guide extension, extending substantially perpendicularly to the locking portion and adapted to slide in a guide groove of the frame.

[0030] This guide extension makes it possible to simply ensure the guidance of a sliding opening, without the need to provide additional means for this function.

[0031] According to another particular feature of the proposed technique, each of the rebate cheeks carries a sealing gasket.

[0032] Thus, sealing is ensured in an efficient and discreet manner, without the need to previously mount a seal on the edges of the glazing.

[0033] The proposed technique relates, according to a second aspect, to a joinery of the type door or window, comprising at least one opening as described above.

[0034] The proposed technique relates, according to a third aspect, to a manufacturing or maintenance process for an opening as described above, the process comprising the following steps: - application of an external constraint on the groove cheeks, so as to bring them closer together under the effect of an external constraint so as to move the rebate cheeks away from each other; - installation of the glazing in the body, between the rebate cheeks; - removal of the constraint, so that the body assumes the holding position; - insertion of locking means between the groove cheeks.

[0035] According to another particular feature of the proposed technique, the manufacturing process comprises the following preliminary steps: - obtaining a profile forming the cheeks; - insertion of a thermal break in and between the cheeks; - securing a sealing gasket to each of the rebate cheeks.

[0036] According to another particular feature of the proposed technique, the manufacturing process includes, for a maintenance operation, the following steps: - removal of the blocking means; - application of an external constraint on the groove cheeks, so as to bring them closer together under the effect of an external constraint so as to move the rebate cheeks away from each other; - removal of the glazing. 4.

[0038] 5. Detailed description of the proposed technique

[0039] For the sake of clarity, the same elements are designated by the same references on the different figures.

[0040] Furthermore, in the present description, the terms orientation and positioning are used arbitrarily with reference to an installed position of the opening, that is to say, when it is arranged inside a frame placed in a bay made in a wall, and is oriented according to the plane of the wall (that is to say substantially perpendicular to the ground), so as to arrange the opening substantially vertically.

[0041] The cross-section of the frame profile according to the invention is shown in the figures in an orientation corresponding to the lower edge of the glazing. This orientation must obviously be transposed for the other edges.

[0042] 5.1 General Principle

[0043] At the cost of a not obvious approach, the inventors of the present application have identified a new and inventive approach ensuring effective retention of the glazing in the frame, while increasing the glazing area and simplifying assembly and maintenance.

[0044] The proposed technique allows the production of a joinery opening comprising a glazing mounted in a frame, at least one side of which is formed by a body having two cheeks, the first parts of which, called rebate cheeks, overlap an edge of the glazing.

[0045] The general principle of the proposed technique is based on the implementation of a deformable frame so that second parts of the cheeks, called groove cheeks, can be brought together under the effect of an external stress so as to move the rebate cheeks away from each other to allow the glazing to be placed in the body, the rebate cheeks and the groove cheeks returning to a holding position in the absence of stress, in which the glazing is held between the rebate cheeks.

[0046] This approach can be likened to the operation of a clothespin: by bringing the lower parts of the cheeks (groove cheeks) together, the upper parts of these same cheeks (rabbet cheeks) are spread apart, allowing easy insertion of the edge of the glazing. By releasing the groove cheeks, the rabbet cheeks press firmly against the edge of the glazing.

[0047] The proposed technique further provides means for locking the groove cheeks in the holding position. Thus, once the glazing is in place in the rebate, that is, between the two groove cheeks, the body is locked in its holding position. Using the analogy of a clothespin, the clothespin is locked so that it can no longer be opened.

[0048] Such a deformable frame approach goes against the a priori assumptions of a person skilled in the art who believed that this frame should be as rigid as possible in order to ensure effective support of the glazing.

[0049] An opening conforming to the proposed technique can be implemented in particular in joinery of the type doors or windows with sliding opening, and can also be adapted to a hinged opening.

[0050] The proposed technique also relates to joinery comprising at least one such opening and to the manufacturing process of such an opening.

[0051] 5.2 Description of an illustrative embodiment

[0052] Figures IA and IB illustrate, in cross-sectional and schematic views, an example of a glazed opening conforming to a first embodiment of the proposed technique. [Fig. IA] shows such a glazed opening in its assembled state. [Fig. 1B] shows the same opening partially exploded so as to distinguish its constituent elements.

[0053] Classically, a joinery opening 1, of the door or window type, includes a frame supporting a glazing 20.

[0054] Such a frame is formed of four sides, or edges, namely two uprights connected to two crossbars (of which only the lower crossbar is shown in the figures). These frame sides are generally profiles, either metallic (in particular aluminum or steel) or plastic (in particular PVC).

[0055] Each side of the frame is formed by a body 100 comprising two cheeks 110, 120, arranged opposite each other, connected together by means of a connecting element 130.

[0056] As already indicated, each cheek 110, 120 is a substantially flat piece, of low thickness, provided with a receiving portion 1101, 1201 respectively of the connecting element 130 to the other cheek so as to form the body 100.

[0057] The body 100 thus has a first cheek 110, intended to be oriented towards the interior of a building equipped with the joinery, and a second cheek 120, intended to be oriented towards the exterior of the same building.

[0058] Each cheek 110, 120 has a first part 110A, 120A, called the rebate cheek, and a second part 110B, 120B, called the groove cheek, opposite the first part 110A, 120A respectively. The body 100 thus has a rebate 111 and a groove 112.

[0059] The connecting element 130, also called a thermal break, extends substantially perpendicularly to the cheeks 110, 120 and, together with them, defines the general shape of an "H". In other words, the connecting element 130 forms on one side a rebate bottom 111 and on the other side a groove bottom 112.

[0060] The glazing 20 has edges 200, that is to say peripheral portions, housed in the rebate 111 of the frame of the opening 1. In other words, for each side of the frame, the rebate cheeks 110A, 120A overlap an edge 200 of the glazing 20. The glazing 20 thus has a first face, called the inner face 210, a portion of which is arranged opposite the first cheek 110, and a second face, called the outer face 211, a portion of which is arranged opposite the second cheek 120.

[0061] According to the proposed technique, for each side of the frame, the body 111 is deformable so as to allow the insertion and then the holding of the edge 200 of the glazing 20 between the first and second cheek 110, 120.

[0062] The deformation of the body 100 is obtained by pivoting the first and second cheek 110, 120 around the bottom of the rebate 112, i.e. of the thermal break 130, which can deform slightly.

[0063] The body 100 is deformable so that, under the effect of an external stress, the groove cheeks 110B, 120B can be brought closer together. Such a bringing together of the groove cheeks 110B, 120B causes the rebate cheeks 110A, 120A to move further apart.

[0064] Thus, the edge 200 of the glazing 20 can easily be placed in the rebate 111, and more precisely between the rebate cheeks 110A, 120A, as will be detailed in relation to figures 2 and 3.

[0065] The body 100 is designed such that, in the absence of external stress, the rebate cheeks 110A, 120A and the groove cheeks 110B, 120B tend to return to their respective initial positions. In other words, the groove cheeks 110B, 120B tend to move away from each other while the rebate cheeks 110A, 120A tend to move closer together.

[0066] Thus, by moving closer together, the rebate cheeks 110A, 120A assume a position that holds the edge 200 of the glazing 20 previously placed between them. In other words, the rebate cheeks 110A, 120A exert a pinching force on the edge 200 of the glazing 20.

[0067] Means for locking the groove cheeks 110B, 120B then lock the rebate cheeks 110A, 120A in the position for holding the edge 200 of glazing 20.

[0068] To do this, and for each side of the frame, the locking means are inserted into the groove 112 of the body 100.

[0069] More specifically, each locking means is formed by a locking key 30 disposed between and bearing against the rebate cheeks 110A, 120A. This locking key 30 may extend over the entire length of the body 100, or a substantial portion, for example at least 90%, of the length. Alternatively, several smaller keys may be distributed along this length.

[0070] Each locking key 30 comprises a locking portion 300, of elongated shape, having two locking ends 310, 320. Each locking end 310, 320 has a shape complementary to a locking structure provided on each of the groove cheeks 110B, 120B respectively.

[0071] Thus, the locking key 30 is configured to exert an internal, locking force on the groove cheeks 110B, 120B so as to keep them apart, and therefore to keep the rebate cheeks 110A, 120A close together, in the holding position. This ensures that the rebate cheeks 110A, 120A cannot, accidentally or unintentionally, be separated from each other, and therefore the glazing 20 is permanently held correctly.

[0072] In this embodiment, each rebate cheek 110A, 120A carries a first flexible seal 140, 141. To this end, each rebate cheek 110A, 120A has a retaining portion 1102, 1202 of the associated first seal 140, 141. The retaining portions 1102, 1202 are oriented opposite each other so as to position the first seals 140, 141 between the first and second cheeks 110, 120. The first seals 140, 141 are thus configured to engage with the inner and outer faces 210, 211 of the glazing 20 when its edge 200 is inserted into the rebate 111 of the body 100.

[0073] Such first seals 140, 141 ensure internal and external sealing between the glazing 20 and the body 100. These first seals 140, 141 also minimize the risk of damage to the glazing 20 by the rebate cheeks 110, 111. These flexible first seals 140, 141 also contribute to maintaining the glazing 20 in the rebate 11.

[0074] In the illustrated example, the frame is formed of four bodies 100, defining the four sides of the opening 1, the first and second cheeks of which 110, 111 are made of aluminium.

[0075] The first and second cheeks 110, 111 are portions of a profile having identical cross-sections. The first and second cheeks 110, 120 are arranged opposite each other and substantially symmetrically with respect to an axis (not shown) passing through the glazing 20.

[0076] Furthermore, for each cheek 110, 120, the receiving portion 1101, 1201 of the connecting element 130 is located between the retaining portion 1102, 1202 of the first joint 140, 141 and the insertion portion 1103, 1203 of the locking key 30. In other words, when the connecting element 130 is joined to the cheeks 110, 120, the body 100 has a cross-section substantially in the shape of an “H”.

[0077] Such an "H" configuration allows the body 100 to be easily deformable between the desired positions, while minimizing the constraints necessary to do so.

[0078] The receiving portions 1101, 1201 of the connecting element 130 are formed by grooves extending over the entire length of the cheeks 110, 120.

[0079] The retaining portions 1102, 1202 of the first joints 140, 141 are formed by grooves extending over the entire length of the rebate cheeks 110A, 120A.

[0080] The insertion portions 1103, 1203 of the locking key 30, also called locking structures, are formed by grooves extending over the entire length of the groove cheeks 110B, 120B.

[0081] Such grooves make it possible, in particular, to simplify the manufacture of the first and second cheeks 110, 120. Indeed, they can thus be produced in the form of a profile by extrusion. These grooves also allow the associated complementary elements (first seals, locking key, and connecting element) to be positioned along the entire length of the body. This results in a better distribution of the associated forces.

[0082] In this example of implementation, the thermal break 130 is formed by a strip of plastic material, and more specifically by a polyamide.

[0083] The thermal break 130 has lateral ends 1301, 1311 arranged and held in the receiving portions 1101, 1201 of the cheeks 110, 111.

[0084] The dimensions of the thermal break 130 are determined in particular according to the thickness of the glazing 20 in order to ensure effective retention of the latter between the rebate cheeks 110A, 120A.

[0085] In the illustrated example, each locking key 30 is made of a metallic material, specifically steel, so as to contribute to the rigidity of the opening 1 in particular. Of course, the locking key can be made of other materials, such as polyvinyl chloride (PVC) or a suitable synthetic material, for example.

[0086] The locking key 30 is substantially in the shape of an elongated plate whose length is a function of the length of the body 100.

[0087] Furthermore, the locking key 30 has a width whose value is determined according to the thickness of the glazing 20 so that the cheeks 110, 120 are parallel to each other when the opening 1 is assembled.

[0088] This locking key 30 has, at its lateral ends, the locking portions 310, 320 configured to be arranged and held in the insertion portions 1103, 1113 of the rebate cheeks 110, 111.

[0089] When the locking key 30 is installed in the body 100, the locking portions 310, 320 of the locking key 30 are substantially parallel to the connecting element 130.

[0090] Furthermore, in the illustrated example, the first seals 140, 141 are made of an elastomeric material, and more specifically of a thermoplastic elastomer (TPE). Obviously, other elastomers can be considered alternatively, such as ethylene-propylene-diene monomer (EPDM).

[0091] Each first seal 140, 141 further comprises at least one contact surface with the glazing 200 having a low Shore A hardness. The first seals 140, 141 thus exhibit strong adhesion, and therefore an anti-slip function of the glazing 20 once mounted in the frame of the opening 1.

[0092] These first seals 140, 141 are entirely disposed and contained within the rebate 111 of the body 100, that is to say, within a ZCH overlap zone of the glazing 20 and rebate cheeks 110A, 120A. Such an arrangement makes it possible in particular to conceal the first seals 140, 141 inside the frame of the opening 1. This reduces the glazed area 20 covered by the first seals 140, 141. This results in an improvement in the glazed area and the aesthetics of the opening 1.

[0093] Furthermore, each first seal 140, 141 has a flat surface of predetermined width, configured to engage with the associated inner or outer face 210, 211 of the glazing 20. This arrangement increases the contact area between the glazing 20 and the frame of the sash 1. This flat support of the first seal 140, 141, in particular, minimizes the risk of the frame pivoting relative to the glazing 20. This results in improved resistance to pull-out (wind load) of the glazing 20.

[0094] Figure 2 shows a simplified flowchart of a manufacturing and maintenance process for such a glazed window or door opening. Figure 3 illustrates certain steps of the process in question.

[0095] The manufacturing process includes steps for forming the frame of the opening 1, as illustrated in Figure 3A.

[0096] Starting from a raw aluminium bar, obtaining SI of at least one profile forming the first and second plays 110, 120 to the desired dimensions.

[0097] Next, the thermal break 130 is inserted S2 into each cheek 110, 120 so as to form the body 100 of the opening frame. To do this, the lateral ends of the thermal break 130 are slid into the grooves forming the receiving portions provided in the cheeks 110, 120.

[0098] A step of securing the first seals 140, 141 on each of the rebate cheeks 110A, 120A is also provided. To do this, the first seals 140, 141 are inserted, by sliding, into the grooves forming the retention portions provided in the first and second cheek 110, 120.

[0099] The aforementioned steps are carried out for the formation of each side of the frame, that is to say for the two uprights and the two crossbars.

[0100] After the frame is formed, the manufacturing or maintenance process includes applying an external stress S4 to the groove 112 of the body 100, i.e., to the groove cheeks 110B, 120B, as illustrated in Figure 3B. Applying such a stress brings the groove cheeks 110B, 120B closer together, and therefore moves the rebate cheeks 110A, 120A further apart.

[0101] For example, the external constraint is exerted by a clamping device (not shown) removably mounted on the groove cheeks 110B, 120B. This clamping device is mounted using a dedicated tool, which can be manual such as a mallet.

[0102] The process then includes, during the application of the external stress, the placement S5 of the glazing 20 in the rebate 111 of the body 100, i.e. between the rebate cheeks 110A, 120A, as illustrated in figure 3C.

[0103] Once the edge 200 of the glazing 20 is housed in the rebate 111, as illustrated in figure 3D, the method includes the removal S6 of the external stress applied on the groove cheeks 110B, 120B, i.e. the removal of the pinching device.

[0104] Thus, the body 100 tends to return to an initial (unconstrained) position until the first seals 140, 141 engage with the glazing 20. In this configuration, the body 100 is said to be in the position of holding the glazing 20, as illustrated in figure 3E.

[0105] The insertion S7 of the locking key 30 between the groove cheeks 110B, 120B is then planned, as illustrated in figure 3F.

[0106] To do this, a first locking portion 320 of the locking key 30 is inserted into a first insertion portion 1203 of the second groove cheek 120. The locking key 30 is then rotated until the second locking portion 310 is inserted into the second insertion portion 1103 of the first groove cheek 110. In other words, the locking key 30 is fixed by snapping into the groove 112 of the body 100.

[0107] Inserting the locking key 30 (S7) into the groove 112 of the body 100 allows the groove cheeks 110B, 120B to be held apart from each other in the holding position, as illustrated in Figure 3G. This also allows the groove cheeks 110A, 120A to exert a pinching force on the glazing 20.

[0108] The aforementioned steps are carried out for the assembly on each side of the frame on the glazing 20, i.e. for the two uprights and the two crossbars.

[0109] These uprights and crossbars are then assembled to form a single-piece frame. In this example, the assembly is achieved using additional connecting pieces, such as brackets (not visible).

[0110] The method further comprises, for a maintenance operation, several steps, not illustrated, involving the removal S8 of the locking keys 30. Then, the application S9 of an external force on the groove cheeks 110B, 120B, so as to bring them closer together and thus move the rebate cheeks 110A, 120A further apart. Finally, the removal S10 of the glazing 20 can be carried out.

[0111] It appears that the manufacture and maintenance of an opening 1, conforming to the proposed technique, are relatively simple. This therefore results in a reduction of the arduousness of the work for the operators.

[0112] 5.3 Other illustrated embodiments

[0113] Figures 4 to 6 relate to a glazed opening according to a second embodiment of the proposed technique.

[0114] Figure 4 shows a structural example of such a glazed opening. Figure 5 shows such a glazed opening arranged in a window or door frame. Finally, Figure 6 illustrates certain steps of the manufacturing and maintenance process, described previously in relation to Figure 2, applied to such a glazed opening.

[0115] This second embodiment differs from the first embodiment in the structure of the thermal break and in the structure of the locking means. For reasons of clarity and conciseness, the elements common to and identical to the first embodiment are not described.

[0116] In this second embodiment, the thermal break 130 of the opening 1 has a deformable structure allowing a variation in the value of its width 1.

[0117] The implementation of such a thermal break structure 130 allows a variation of the spacing between the first and second cheek 110, 120, and therefore the frame to adapt to different thicknesses e of glazing 20.

[0118] In this second embodiment, the locking key 30 further carries a guide extension 330 adapted to slide in a guide groove 41 of the frame 4, as illustrated in [Fig.5].

[0119] The guide extension 330 is located substantially in the center of the locking key 30 and extends substantially perpendicularly to the locking portions 310, 320. In other words, the locking key 30 is substantially T-shaped. The horizontal bar of the locking key 30 provides the locking function, while the vertical portion provides a sliding guide function for the window or French window in a rail provided for this purpose.

[0120] Such a configuration, making the locking key multifunctional, reduces the number of component parts of the joinery. This results in easier manufacturing and maintenance of the joinery. It also reduces the amount of resources required for its manufacture.

[0121] In the illustrated example, the thermal break 130 has two deformable sinusoidal structures 131, 132, connected by a central tubular portion 133. This allows it to adapt to a slight variation in the thickness of the glazing, without damaging the thermal break or its effectiveness.

[0122] Obviously, any other deformable structure allowing such a variation in the width 1 of the thermal break can be considered alternatively.

[0123] Furthermore, in the illustrated example, the extension 330 has a free end 331 which, after insertion into the groove 41 of the frame 4, is able to rest on a mobile carriage 42 moving inside the frame 4, as illustrated in [Fig.5].

[0124] Such a configuration makes it possible in particular to simplify the assembly and maintenance of the joinery, while allowing efficient sliding of the glazed opening.

[0125] Fig. 7 presents, according to a cross-sectional view, an example of an opening according to a third embodiment of the proposed technique.

[0126] This third embodiment differs from the second embodiment only in the structure of the blocking means. For reasons of clarity and conciseness, the elements common to and identical with the second embodiment are not described.

[0127] In this third embodiment, the extension 330, suitable for sliding in a guide groove of the frame (not shown), is located in the vicinity of one of the locking portions 310, 320 of the locking key 30.

[0128] Such an arrangement of the extension is particularly interesting for casement joinery.

[0129] Fig. 8 presents, according to a cross-sectional view, an example of an opening according to a fourth embodiment of the proposed technique.

[0130] This fourth embodiment differs from the third embodiment only in the structure of the blocking means. For reasons of clarity and conciseness, the elements common to and identical with the third embodiment are not described.

[0131] In this fourth embodiment, the extension 330 of the locking key 30 carries at least one second flexible seal 340 adapted to bear against a portion of the frame. Such a second seal 340 ensures a seal between the sash 1 and the frame (not shown).

[0132] In the illustrated example, the second seal 340 is made of an elastomeric material, and more specifically of a thermoplastic elastomer (TPE).

[0133] Fig. 9 presents, according to a cross-sectional view, an example of an opening according to a fifth embodiment of the proposed technique.

[0134] This fifth embodiment differs from the second embodiment only in the structure of the blocking means. For reasons of clarity and conciseness, the elements common to and identical with the second embodiment are not described.

[0135] In this fifth embodiment, and in a manner analogous to the first embodiment, the locking key 30 is devoid of a guide extension capable of sliding in a guide groove of the frame.

[0136] It may be particularly advantageous to implement such a locking key when translational guidance is not required, as is notably the case for the uprights of the opening.

[0137] Fig. 10 presents, according to a cross-sectional view, an example of an opening according to a sixth embodiment of the proposed technique.

[0138] This sixth embodiment differs from the fifth embodiment only in the structure of one side of the opening body. For reasons of clarity and conciseness, the elements common to and identical to the fifth embodiment are not described.

[0139] In this sixth embodiment, the groove cheek 110B of the first cheek 110 carries at least one third flexible seal 150 adapted to bear against a portion of the frame (not shown). Such a third seal 340 ensures a seal between the sash 1 and the frame (not shown).

[0140] In the illustrated example, the third seal 150 is made of an elastomeric material, and more specifically of a thermoplastic elastomer (TPE).

[0141] Furthermore, the third joint 150 is supported by an extension 110B' of the groove cheek 110B.

[0142] Fig. 11 presents, according to a cross-sectional view, an example of an opening according to a seventh embodiment of the proposed technique.

[0143] This seventh embodiment differs from the first embodiment primarily in the structure of the opening frame. For reasons of clarity and conciseness, the elements common to and identical to the first embodiment are not described.

[0144] In this seventh embodiment, each side of the frame is formed by a single-piece body 100. In other words, the first and second cheeks 110, 120 as well as the thermal break 130 are formed from a single piece.

[0145] The one-piece body 100 is made of synthetic material in order to give it the deformation properties necessary for the implementation of the proposed technique.

[0146] More specifically, and in a manner analogous to the first embodiment, the thermal break 130 is deformable so as to allow the insertion and then the holding of the glazing 20 between the first and second cheek 110, 120.

[0147] Such a one-piece configuration allows for easy assembly of the opening sash, and by extension, of the joinery. Such a structure also improves the lifespan of the opening sash,

[0148] In the illustrated example, the one-piece body 100 is made of polyvinyl chloride (PVC), and obtained by extrusion.

[0149] Furthermore, the thermal break 130 has the shape of a hollow tubular element with an ovoid cross-section. This allows it to adapt to slight variations in the thickness of the glazing, without damaging the thermal break or its effectiveness.

[0150] 5.4 Other embodiments and variants not illustrated

[0151] In some of the illustrated embodiments, the cheeks of the opening are made Made of aluminum, this allows for a rigid yet thin, and therefore discreet, frame. Obviously, any rigid material that inherently possesses... Similar properties can be used. For example, cheeks made of steel or synthetic material, such as polyvinyl chloride (PVC), can be considered.

[0152] In the illustrated embodiments, each side of the opening frame is formed by a deformable body conforming to the proposed technique. In another, not illustrated, embodiment, only two, or even three, of the sides of the frame have deformable bodies conforming to the proposed technique.

[0153] In the illustrated embodiments, the blocking means are made of polyamide. In another embodiment, not illustrated, the blocking means are made of polyvinyl chloride (PVC) or a suitable synthetic material.

[0154] In the illustrated embodiments, the means for locking the groove cheeks are formed by a locking key, a locking portion of which extends between said groove cheeks. In another embodiment, not illustrated, the locking means comprise several locking keys so as to permanently lock the device in the holding position.

[0155] In the illustrated embodiments, the locking key extends along the entire length of the body. In another embodiment, not illustrated, the locking key, or other locking means, extends over 90% of the body's length. This is the case, for example, when the locking key is interrupted near the corners of the sash. According to yet another embodiment, not illustrated, the locking means comprise several locking keys distributed at regular intervals, for example every 5 or 10 cm, along the body. Such implementations ensure effective locking of the glazing in the frame, while reducing the quantity of material required to manufacture the locking means. This results, in particular, in a reduction of the overall mass of the window or door assembly, which therefore becomes easier to handle (especially for installation) and also more environmentally friendly.

[0156] In the illustrated embodiments, the connecting element of the cheeks also performs the function of a thermal break, due to the flexible material from which it is made. In another embodiment, not illustrated, the thermal insulation and the connection of the cheeks are achieved by separate elements. For example, the cheeks are connected to each other by a connecting element made of a rigid material, such as steel. In such a configuration, the deformation of the body is achieved by implementing a pivot joint between the rigid connecting element and at least one cheek. In this example, the thermal break function is achieved by means of locking devices, which are made of polyvinyl chloride.

[0157] In the illustrated embodiments, each of the rebate cheeks has a first seal. In another embodiment, not illustrated, the opening is without such initial seals. This type of arrangement can be considered, in particular, when the side panels are made of a material that ensures a watertight seal with the glazing. This simplifies the design and manufacture of the sash.

[0158] Obviously, the proposed technique is not limited to the embodiments described above and provided solely by way of example. It encompasses various modifications, alternative forms and other variants that a person skilled in the art may consider within the framework of the proposed technique, and in particular all combinations of the different embodiments described above, which may be taken separately or in combination.
