Abstract
Description
1. Scope of the proposed technology
[0001] The proposed technology covers the building sector, and more specifically, joinery intended to equip the openings of a building.
[0002] More specifically, the proposed technique concerns joinery elements, particularly the glazed openings of such joinery.
[0003] Such glazed openings have many applications, particularly for glazed joinery such as sliding or hinged 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 window consists of a frame with a projecting edge, called a rebate, on one side. A pane of glass is fitted into the frame so that one edge of the glass rests in the rebate. A glazing bead is then attached to the opposite side of the frame to hold the glass in place. In other words, the glazing bead applies a clamping force to the edge of the glass.
[0007] This approach requires the use of a relatively thick frame to secure the glazing bead. These significant dimensions are necessary to provide the frame with sufficient rigidity, particularly for the design of a large opening, that is, an opening fitted with large panes of glass.
[0008] This approach, however, has drawbacks. The frame's large size makes it particularly noticeable. Besides sometimes being considered unsightly, such a massive frame limits the glazing area of the opening. This results in reduced natural 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 effectively secure a pane of glass, especially a large one.
[0009] A casement window, on the other hand, includes glazing mounted in a frame, at least one edge, or side, of which 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 with two side cheeks, and receiving the edge of the glazing.
[0011] This approach requires the use of a seal on the edge of the glazing to ensure it remains in position within the rebate. More specifically, the seal has a U-shaped cross-section, designed to encircle the edge of the glazing, with each arm incorporating locking mechanisms. These locking mechanisms are configured to work in conjunction with additional mechanisms located on the first ends of the rebate cheeks during the insertion of the glazing between the cheeks.
[0012] This approach also has drawbacks. The clamping force exerted by the snap-fit mechanisms 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 lead to glazing retraction. This phenomenon is particularly noticeable when installing large panes of glass. The snap-fit mechanisms 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 mechanisms remains visible. This portion of the gasket, commonly called flashing, also detracts from the aesthetics and the visible glazing area of the opening.
[0013] Another drawback is that the thickness of the glazing can vary slightly, by a few tenths of a millimeter, and that fitting and maintaining the seal can be difficult or insufficiently effective.
[0014] Therefore, there is a need to provide a glazed opening technique that does not present all or some of the disadvantages of current solutions. 3. Summary of the proposed technique
[0015] The proposed technique relates, in a first aspect, to a joinery element such as a door, window or interior partition comprising 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.
[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 force, thereby moving the rebate cheeks apart to allow the glazing to be installed in the body. Furthermore, the rebate and groove cheeks return to a holding position in the absence of force, in which the glazing is held between the rebate cheeks.
[0017] Such a joinery element further includes means for locking the groove cheeks in the holding position.
[0018] This type of joinery element significantly improves the glazing's pull-out resistance to the frame, without the need for adhesive. This simplifies installation and allows for smaller rebates, resulting in a more discreet frame and a larger glazed area. It also facilitates efficient and straightforward management of glazing thickness tolerances of several tenths of a millimeter.
[0019] According to a particular feature of the proposed technique, the locking means include 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 joinery element (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 glazing thicknesses.
[0023] Depending on one particular aspect, the said breaker can be made of polyamide or metal, in particular stainless steel.
[0024] 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.
[0025] Thus, the assembly of the locking key is simple, efficient, and reversible.
[0026] According to another particular feature of the proposed technique, the locking key extends over at least 90% of the body length.
[0027] According to another particular feature of the proposed technique, the joinery element includes at least two locking keys distributed in the body.
[0028] For example, locking means include several locking keys distributed at regular intervals, every 5 or 10 cm for example, along the body.
[0029] According to another particular feature of the proposed technique, the locking keys are made of metal, PVC, polyamide or a suitable synthetic material.
[0030] The cheeks can be rigid. However, in a particular embodiment, the thickness of said groove cheeks is adapted so that they are flexible.
[0031] In a particular implementation of the invention, said joinery element is an opening.
[0032] In this case, according to another particular feature of the proposed technique, at least one of the locking keys carries a guide extension, extending substantially perpendicularly to the locking portion and capable of sliding in a guide groove of the frame.
[0033] This guide extension makes it possible to easily guide a sliding door, without needing to provide additional means for this function.
[0034] According to another particular feature of the proposed technique, each of the rebate cheeks carries a sealing gasket.
[0035] Thus, the seal is ensured in an efficient and discreet manner, without the need to previously mount a seal on the edges of the glazing.
[0036] The proposed technique relates, according to a second aspect, to a joinery of the door or window type, comprising at least one joinery element, in particular an opening, as described previously.
[0037] The proposed technique relates, according to a third aspect, to a manufacturing or maintenance process for a joinery element, in particular an opening as described above, the process comprising the following steps: application of an external force on the groove cheeks, so as to bring them closer together under the effect of an external force so as to move the rebate cheeks away from each other; placement of the glazing in the body, between the rebate cheeks; removal of the force, so that the body takes the holding position; insertion of the locking means between the groove cheeks.
[0038] According to another particular feature of the proposed technique, the manufacturing process includes 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.
[0039] According to another particular feature of the proposed technique, the manufacturing process includes, for a maintenance operation, the following steps: removal of the locking means; application of an external force on the groove cheeks, so as to bring them closer together under the effect of an external force so as to move the rebate cheeks away from each other; removal of the glazing. 4.

Detailed description of the proposed technique
[0041] The technique of the invention relates to a joinery element comprising glazing, in particular an opening. It may also be a fixed panel of a window or part of a window, or an element of an interior partition. An opening is described as an example below.
[0042] For the sake of clarity, the same elements are designated by the same references on the different figures.
[0043] Furthermore, in this description we use the terms orientation and positioning by arbitrarily referring to an installed position of the opening, that is, when it is placed inside a frame set in a bay made in a wall, and is oriented according to the plane of the wall (that is, substantially perpendicular to the ground), so as to place the opening substantially vertically.
[0044] 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. 5.1 General principle
[0045] At the cost of a not obvious approach, the inventors of this 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.
[0046] 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.
[0047] 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 groove cheeks returning to a holding position in the absence of stress, in which the glazing is held between the rebate cheeks.
[0048] 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 for easy insertion of the edge of the glazing. By releasing the groove cheeks, the rabbet cheeks press firmly against the edge of the glazing.
[0049] The proposed technique also includes means for locking the groove cheeks in the holding position. Thus, once the glazing is in place within the rebate, that is, between the two groove cheeks, the frame is locked in this position. Using the analogy of a clothespin, this locks the pane so that it can no longer be opened.
[0050] Such a deformable frame approach goes against the a priori from the expert who believed that this frame must be as rigid as possible in order to ensure effective support of the glazing.
[0051] An opening conforming to the proposed technique can be implemented in particular in joinery such as sliding doors or windows, and can also be adapted to a hinged opening.
[0052] The proposed technique also relates to joinery comprising at least one such opening, as well as to the manufacturing process of such an opening. 5.2 Description of an illustrative embodiment
[0053] THE Figures 1A and 1B They illustrate, through cross-sectional and schematic views, an example of a glazed opening conforming to a first embodiment of the proposed technique. Figure 1A represents such a glazed opening in its assembled state. figure 1B represents this same opening in a partially exploded manner so as to distinguish its constituent elements.
[0054] Typically, a joinery opening 1, such as a door or window, includes a frame supporting a glazing 20.
[0055] Such a frame consists 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 (particularly aluminum or steel) or plastic (particularly PVC).
[0056] 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.
[0057] 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.
[0058] 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.
[0059] 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.
[0060] 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 cross-section. In other words, the connecting element 130 forms, on the one hand, a rebate bottom 111 and, on the other hand, a groove bottom 112.
[0061] 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.
[0062] 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.
[0063] 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. the thermal break 130, which can deform slightly.
[0064] 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.
[0065] Thus, the edge 200 of the glazing 20 can easily be fitted into the rebate 111, and more specifically between the rebate cheeks 110A, 120A, as will be detailed in relation to the figures 2 And 3 .
[0066] The body 100 is designed so 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 towards each other.
[0067] Thus, by moving closer together, the rebate cheeks 110A and 120A assume a position that holds the edge 200 of the glazing 20 previously placed between them. In other words, the rebate cheeks 110A and 120A exert a pinching force on the edge 200 of the glazing 20.
[0068] Means of locking the groove cheeks 110B, 120B then lock the rebate cheeks 110A, 120A in the position of retaining the edge 200 of glazing 20.
[0069] To do this, and for each side of the frame, the locking means are inserted into the groove 112 of the body 100.
[0070] More specifically, each locking mechanism consists of a locking key 30 positioned between and bearing against the rebate cheeks 110A, 120A. This locking key 30 can extend along the entire length of the body 100, or a substantial portion, for example, at least 90%, of the length. Alternatively, several smaller keys can be distributed along this length.
[0071] 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.
[0072] Thus, the locking key 30 is configured to exert an internal, locking force on the groove cheeks 110B and 120B, keeping them separated and therefore holding the rebate cheeks 110A and 120A together in the holding position. This ensures that the rebate cheeks 110A and 120A cannot be accidentally or unintentionally separated, and therefore that the glazing 20 is permanently held correctly.
[0073] In this embodiment, each rebate cheek 110A, 120A carries a first flexible seal 140, 141. To achieve this, 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.
[0074] These 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 holding the glazing 20 in the rebate 11.
[0075] 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 110, 111 of which are made of aluminium.
[0076] The first and second cheeks 110, 111 are portions of a profile with 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.
[0077] 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”.
[0078] Such an "H" configuration allows the body 100 to be easily deformable between desired positions, while minimizing the constraints required to do so.
[0079] The receiving portions 1101, 1201 of the connecting element 130 are formed by grooves extending over the entire length of the cheeks 110, 120.
[0080] 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.
[0081] 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.
[0082] Such grooves simplify the manufacturing of the first and second cheeks 110 and 120. They can be produced as a profile through extrusion. These grooves also allow for the placement of associated components (first seals, locking key, and connecting element) along the entire length of the body. This results in a better distribution of the associated stresses.
[0083] In this implementation example, the thermal break 130 is formed by a strip of plastic material, and more specifically by a polyamide.
[0084] The thermal break 130 has lateral ends 1301, 1311 arranged and held in the receiving portions 1101, 1201 of the cheeks 110, 111.
[0085] 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.
[0086] In the illustrated example, each locking key 30 is made of a metallic material, specifically steel, 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.
[0087] 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.
[0088] 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.
[0089] 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.
[0090] 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.
[0091] Furthermore, in the illustrated example, the first seals 140, 141 are made of an elastomeric material, specifically a thermoplastic elastomer (TPE). Of course, other elastomers could be considered alternatively, such as ethylene propylene diene monomer (EPDM).
[0092] Each first seal 140, 141 also includes at least one contact surface with the glazing 200 having a low Shore A hardness. The first seals 140, 141 thus provide strong adhesion, and therefore an anti-slip function for the glazing 20 once mounted in the frame of the sash 1.
[0093] These first seals 140, 141 are entirely positioned and contained within the rebate 111 of the body 100, that is, within an overlapping zone Z CH of the glazing 20 and the rebate cheeks 110A, 120A. This arrangement makes it possible, in particular, to conceal the first seals 140, 141 inside the frame of the sash 1. This reduces the surface area of the glazing 20 covered by the first seals 140, 141. This results in an improved glazed area and an enhanced aesthetic appearance of the sash 1.
[0094] 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 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.
[0095] There figure 2 This represents a simplified flowchart of a manufacturing and maintenance process for such a glazed window or door. figure 3 illustrates certain steps of the process in question.
[0096] The manufacturing process includes steps for forming the frame of the opening 1, as illustrated in figure 3A .
[0097] Starting from a raw aluminum bar, obtaining S1 of at least one profile forming the first and second plays 110, 120 to the desired dimensions.
[0098] Next, the thermal break 130 is inserted S2 into each cheek 110, 120 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 in the cheeks 110, 120.
[0099] A step of securing the first joints 140, 141 on each of the rebate cheeks 110A, 120A is also planned. To do this, the first joints 140, 141 are inserted, by sliding, into the grooves forming the retaining portions provided in the first and second cheek 110, 120.
[0100] 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.
[0101] 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 constraint allows the groove cheeks 110B, 120B to be brought closer together, and therefore the rebate cheeks 110A, 120A to be moved further apart.
[0102] For example, the external constraint is exerted by a pinching device (not shown) removably mounted on the groove cheeks 110B, 120B. This pinching device is mounted using a dedicated tool, which can be manual such as a mallet.
[0103] 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, that is to say between the rebate cheeks 110A, 120A, as illustrated in figure 3C .
[0104] Once the edge 200 of the glazing 20 is housed in the rebate 111, as illustrated in 3D figure , the process includes the removal S6 of the external stress applied to the groove cheeks 110B, 120B, i.e. the removal of the pinching device.
[0105] 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 glazing 20 holding position, as illustrated in figure 3E .
[0106] The next step involves inserting the locking key S7 30 between the groove cheeks 110B, 120B, as illustrated in figure 3F .
[0107] 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.
[0108] Inserting the locking key S7 into the groove 112 of the body 100 allows the groove cheeks 110B and 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.
[0109] The aforementioned steps are carried out for the assembly on each side of the frame on the glazing 20, that is to say for the two uprights and the two crossbars.
[0110] 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).
[0111] The procedure 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.
[0112] It appears that the manufacture and maintenance of an opening 1, conforming to the proposed technique, are relatively simple. This therefore translates into a reduction in the physical strain of the work for the operators. 5.3 Other illustrated embodiments
[0113] THE figures 4 to 6relate to a glazed opening according to a second embodiment of the proposed technique.
[0114] There figure 4 presents a structural example of such a glazed opening. figure 5 presents such a glazed opening set within a joinery frame. Finally, the figure 6 illustrates certain steps in the manufacturing and maintenance process, described previously in relation to the 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 the structure of the locking means. For reasons of clarity and conciseness, 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 I.
[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 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 figure 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 and 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 guides the sliding movement of the window or French door in a track designed for this purpose.
[0120] This configuration, which makes the locking key multifunctional, reduces the number of component parts in the joinery. This translates into easier manufacturing and maintenance of the joinery, as well as a reduction in the amount of resources required for its production.
[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 slight variations in the thickness of the glazing, without damaging the thermal break or its effectiveness.
[0122] Obviously, any other deformable structure that allows such a variation in the width I of the thermal break can be considered as an alternative.
[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 figure 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] There figure 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, capable of 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 extension arrangement is particularly interesting for casement windows.
[0129] There figure 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 capable of bearing against a portion of the frame. Such a second seal 340 ensures a watertight seal between the sash 1 and the frame (not shown).
[0132] In the illustrated example, the second 340 seal is made of an elastomeric material, and more specifically of a thermoplastic elastomer (TPE).
[0133] There figure 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 can 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] There Figure 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 110B of the first side 110 carries at least one third flexible seal 150 capable of bearing against a portion of the frame (not shown). Such a third seal 340 ensures a watertight seal between the sash 1 and the frame (not shown).
[0140] In the illustrated example, the third 150 joint 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] There figure 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, 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 monobloc configuration allows for easy assembly of the sash, and by extension, the entire window frame. This structure also improves the lifespan of the sash.
[0148] In the illustrated example, the one-piece 100 body is made of polyvinyl chloride (PVC), and obtained by extrusion.
[0149] Furthermore, the 130 thermal break has the shape of a hollow tubular element with an ovoid cross-section. This allows it to adapt to slight variations in glazing thickness without damaging the thermal break or its effectiveness. 5.4 Embodiment with metal breaker
[0150] According to one variant, illustrated by the Figures 12A(undeformed position before key insertion) and 12B (deformed position after key insertion), the 130 breaker is made of metal, for example stainless steel. This reduces or even eliminates sensitivity to humidity and potential weather-related damage.
[0151] The 130 breaker can notably be made from a rolled stainless steel strip to take the desired shape, such as the one illustrated on the Figures 12A and 12B The breaker is then mounted in the receiving portions 1101, 1201 of each cheek. Each end of the breaker is clamped in the corresponding receiving portion, which includes a movable clamping part 11011, 12011 that assumes an assembly position (dashed line) and then a locking position (solid line). The same principle can, of course, be applied to the various embodiments described above. 5.5 Embodiment with reduced cheek thickness
[0152] Yet another approach is illustrated on the Figures 13A (undeformed position before key insertion) and 13B (deformed position after key insertion), in which the material mass of the cheeks is reduced. In particular, groove cheeks 110B and 120B have a thickness adapted to be deformed, compared to the embodiments described above, so that the cheeks are slightly flexible. As noted on the figure 13B When the key is in place, the groove cheeks are moved away from each other, relative to the position of the figure 13A .
[0153] The profile can be straight or curved, so as to anticipate this deformation and tend to return to a position where the cheeks are parallel.
[0154] In exchange for this flexibility in the cheeks, it is desirable that the 130 breaker, made here of polyamide, be slightly thinner, to be more flexible and accommodate additional deformation, thus limiting its sensitivity to humidity. In other words, the deformation can be distributed between the cheeks and the breaker.
[0155] This approach makes it possible to broaden the range of use, that is to say the range of variation of the thickness of the glass. 5.6 Other embodiments and variations not illustrated
[0156] In some of the illustrated embodiments, the sash sides are made of aluminum, resulting in a rigid yet slim, and therefore discreet, frame. Of course, any sufficiently rigid material with similar inherent properties can be used. For example, sides made of steel or synthetic materials such as polyvinyl chloride (PVC) could be considered.
[0157] In the illustrated embodiments, each side of the opening frame is formed by a deformable body conforming to the proposed technique. In another, unillustrated embodiment, only two, or even three, sides of the frame have deformable bodies conforming to the proposed technique.
[0158] 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.
[0159] In the illustrated embodiments, the means for locking the groove cheeks consist of 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 secure the locking in the holding position.
[0160] In the illustrated embodiments, the locking key extends along the entire length of the body. In another, unillustrated embodiment, 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, unillustrated embodiment, 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 a reduction of the overall mass of the window or door assembly, making it easier to handle (particularly for installation) and also more environmentally friendly.
[0161] In the illustrated embodiments, the connecting element of the cheeks also acts as a thermal break, due to its flexible material. In another embodiment, not shown, 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 mechanisms, which are made of polyvinyl chloride.
[0162] In the illustrated embodiments, each of the rebate cheeks has a first seal. In another, unillustrated embodiment, the sash lacks such first seals. This arrangement can be considered, in particular, when the cheeks are made of a material that ensures a seal with the glazing. This simplifies the design and manufacture of the sash.
[0163] Of course, the proposed technique is not limited to the embodiments described above, which are provided solely by way of example. It encompasses various modifications, alternative forms, and other variations that a person skilled in the art might consider within the framework of the proposed technique, and in particular all combinations of the different embodiments described above, which may be considered separately or in combination. Furthermore, the characteristics described specifically in relation to one or more embodiments may be combined to define other embodiments.
