Description

[0001] The invention relates to a device for fixing a frame of a window and / or door to be fixed in an opening of a building, particularly during renovation. It also relates to the use of this device in a joinery renovation process.

[0002] A window and / or door typically comprises a frame, which forms the fixed structure framing the window or door leaf(s). The frame is fixed to a wall, specifically the masonry section defining the opening around a hole made in the wall's thickness to accommodate the window or door. The frame is secured by fasteners arranged around its perimeter, which are typically L-shaped with two arms. One arm is fixed to the masonry, while the other arm receives the frame. Each fastener is secured with a screw passing through a pre-drilled hole. The wall, particularly when it is an exterior wall forming part of a building's structural framework, is clad with at least one layer of thermal insulation (and possibly acoustic insulation) or a brick partition, this layer itself being faced with a cladding.

[0003] During a renovation involving the removal of the old window or door frame, especially a complete replacement (where not only the window or door frame is removed but also its frame) to be replaced with a new one, the presence of the insulation layer and the remaining wall cladding must be taken into account when installing the new window or door. In this case, installing the window or door frame using angle brackets, as in new construction, is not possible because the fixing bracket on the back of the frame is inaccessible. One arm of the fixing bracket must be inserted between the wall structure and the insulation to be secured to the wall, and then the frame is surface-mounted to the other arm of the bracket. This method requires more labor time because numerous adjustments are necessary to ensure a high-quality installation of the frame and adherence to best practices.

[0004] Furthermore, regulations concerning the installation of joinery and / or the thermal insulation of buildings impose fixing constraints that must be respected. These constraints concern, in particular, the anchoring point of the fixing device to the masonry in order to ensure the solidity of the fixing to the wall; this anchoring point must respect a minimum distance from the reveal surrounding the opening receiving the joinery, or in other words, the distance between the anchoring point of the device and the edge of the wall receiving the frame, a distance which will be referred to in the rest of the description as the anchoring depth of the fixing device.

[0005] In renovation, it proves quite difficult to properly fix the fixing devices of the frame depending on the condition of the wall and the insulation in particular, and therefore also difficult to properly respect this minimum anchoring depth required.

[0006] These constraints also relate to a minimum caulking thickness required for the installation of sealing gaskets. However, this dimension is often not respected, particularly during renovations.

[0007] Furthermore, the fixing brackets are typically made of metal, a material with no thermal insulation properties. They are inserted between the building structure and the insulation, and should include thermal insulation shims on the side where the window or door frame is fixed. However, in practice, these shims are rarely used.

[0008] French patent application FR2970284 proposes a fixing device for a window or door frame that facilitates installation during complete renovations and ensures compliance with the required anchoring depth. This one-piece fixing bracket has an overall L-shape with two arms: the first arm has a through hole, machined into a boss within the first arm, for screw fixing to the masonry; the second arm has a face for receiving the frame to be fixed, equipped with a notch to create an access opening for a screw into the through hole in the first arm, which is machined into the boss that projects towards the inter-arm space of the L-bracket. This boss allows the screw to be inserted at an angle.However, such a fixing bracket still requires a significant amount of labor, as positioning the bracket to achieve the minimum required anchoring depth remains complex. Furthermore, the issue of thermal bridging is not addressed due to the materials used, nor is adherence to minimum dimensions for installing the sealing gaskets. Additionally, during drilling, there is a risk of corrosion due to the removal of the protective coating on the fixing bracket and the contact of the screw with steel (galvanic corrosion with zinc).

[0009] French patent application FR2966211 also proposes a fixing device for a window or door frame that facilitates installation in complete renovation projects. This device comprises a two-pronged bracket that attaches to the masonry and a tab that attaches to the frame. The two components are adjustable to accommodate the height of the fixing tab that receives the frame. However, this device requires improvement, particularly to ensure compliance with the minimum anchoring depth required during the installation of the window or door frame, and more generally to facilitate the installation process.

[0010] The invention aims to resolve, at least in part, the drawbacks of prior art fixing devices, particularly in renovation projects involving complete removal of existing fixtures. One objective of the invention is to provide a fixing device for a window frame, especially in renovation projects involving complete removal of existing fixtures, that facilitates frame installation while ensuring high-quality installation. In particular, the installation must be able to comply with regulations or at least with a recommendation from a building authority or a set of specifications. The invention specifically aims to facilitate compliance with a given anchoring depth, particularly a minimum required value, of the fixing device to the masonry relative to the opening, to ensure the frame's secure attachment to the wall; this minimum depth may be mandated by regulations.The invention secondarily aims to facilitate compliance with a given caulking thickness for the implementation of sealing gaskets, this thickness being able to be regulatory.

[0011] To this end, the invention proposes a device for fixing a window and / or door frame, capable of fixing said frame to an anchoring face of a wall around a reveal intended to receive the window or door. This device comprises at least two fixing elements that can be joined together. According to the invention, one of these two elements is an adjustable fixing bracket that receives the frame, and the other element is an adjustable fixing bracket having a generally elongated shape, the longitudinal direction of which defines the longitudinal direction of the device. This bracket is configured to fix the frame to the anchoring face of the wall and includes adjustment means at least along said longitudinal direction.The two fixing elements include retaining means and longitudinal adjustment means between them to form the fixing device by joining together in an adjustable manner along the longitudinal direction of the fixing bracket. The fixing bracket comprises a first arm and a second arm extending in different planes, the first arm receiving the frame, and the second arm extending along the longitudinal direction of the device and including retaining means and adjustment means enabling it to be assembled with the fixing bracket in an adjustable manner along the longitudinal direction of the fixing bracket.

[0012] Said longitudinal direction is substantially parallel to the plane of the wall anchoring face during the installation of the frame.

[0013] More particularly according to the invention, said adjustment fixing bracket includes at least one fixing hole suitable at least for receiving a means of fixing said device to the anchoring face of the wall, and said adjustment means along the longitudinal direction include at least one adjustment stop, said stop having an inner face longitudinally distant from said fixing hole by a value at least equal to a given anchoring depth value.

[0014] The said given anchoring depth value may in practice correspond to an anchoring depth of said wall fixing device relative to the table which is required by a regulation or at the very least by a recommendation of a building body or for example a specification.

[0015] More specifically, the distance between the mounting hole of the device and the inner face of the stop can be defined as approximately the longitudinal distance from the center of the outlet of said mounting hole opening onto the anchor face of the wall, or from the projection of this point onto a longitudinal line passing through the stop, to the center of the inner face of said stop. The term "outlet" refers to the opening of said mounting hole of said bracket, which is a through hole, located on the anchor face of the wall when the bracket is in place, bearing against the anchor face of the wall.

[0016] According to a preferred embodiment of the invention, at least one adjustment stop comprising the mounting bracket is breakable. More particularly, the stop is integral with a longitudinal portion of the bracket forming an end portion of the bracket, which is breakable, the stop forming the end of the portion.

[0017] According to a particular embodiment of the invention, the respective retaining and adjusting means of the fastening elements, which cooperate with each other, allow the fixing bracket to be moved longitudinally to adjust its longitudinal position while maintaining it in contact with the fixing tab. Preferably, these respective retaining and adjusting means of a fastening element are the same means.

[0018] According to a preferred embodiment of the invention, said first branch and said second branch of the fixing bracket extend in planes substantially perpendicular to each other.

[0019] According to a preferred embodiment of the invention, the longitudinal adjustment means comprising the mounting bracket include at least one longitudinal strip bearing markings to aid in the longitudinal adjustment of the mounting bracket. More particularly, the longitudinal position of the second arm of the bracket is adjustable relative to these markings, which are in particular graduated.

[0020] Preferably, said ruler is integrated into or extended longitudinally by a breakable longitudinal end portion ending with said at least one stop.

[0021] According to a preferred embodiment of the invention, the second arm of the mounting bracket is interlockable with and / or onto the mounting tab. In particular, the second arm of the bracket and the mounting tab each comprise interlocking portions of at least partially cylindrical shape.

[0022] According to a preferred embodiment of the invention, said fastening device includes lockable and unlockable means for securing said fastening elements, in particular of the quarter-turn type.

[0023] According to a preferred embodiment of the invention, said fixing bracket includes a longitudinal end portion whose thickness is substantially equal to a given caulking thickness, to reserve a space for a sealing gasket.

[0024] Advantageously, the device includes a marking means for locating the position of the bracket during the fixing of the frame. Advantageously, said marking means is a longitudinal end portion of said fixing bracket, and in particular said at least one adjustment stop included in said fixing bracket.

[0025] According to a preferred embodiment of the invention, said two fastening elements are made of a material having thermally insulating properties. Said material may further comprise reinforcing elements, for example glass fibers.

[0026] According to a particular embodiment of the invention, said fixing bracket is generally straight, the fixing hole being central from which is located extending on one side a first adjustment part comprising a said integrated ruler or extended by a breakable end portion ending with a said adjustment stop and on the other side a second adjustment part comprising said retaining means and said longitudinal adjustment means, to form said fixing device by being fixed in an adjustable manner along the longitudinal direction of said fixing bracket, or also the longitudinal direction of said bracket.

[0027] According to a preferred embodiment of the invention, the first arm of the bracket comprises fastening means facilitating the attachment of the frame, distributed along the length of the first arm. Advantageously, these fastening means are square-shaped holes.

[0028] According to an advantageous embodiment of the invention, said fixing bracket comprises a curved gripping portion. In particular, said curved portion is integrated into a breakable longitudinal end portion terminating in said adjustment stop. Preferably, said portion has a curvature extending beyond said stop so as to create a gap between said stop and the wall.

[0029] The invention also relates to the use of at least one fastening device in a method of fixing a window or door frame to a wall anchoring surface around an opening intended to receive a window or door, said fastening device being as described above. More particularly and advantageously, the use of said fastening device as described above relates to a method of fixing a window or door frame to a wall anchoring surface after the removal of an old window or door frame.

[0030] In practice, a plurality of devices distributed around the perimeter of the frame are used to fix the frame to it.

[0031] The invention also relates to a method for fixing a window or door frame to an anchoring face of a wall around an opening intended to receive a window or door, particularly after the removal of an old window or door frame, in which at least one fixing device as described above is used, and according to steps comprising a first step in which the adjusting fixing bracket is used alone as a template, by positioning it on the anchoring face of the wall receiving said bracket, said face being covered with at least one layer of insulation, said fixing bracket being disposed in the layer of insulation and such that said at least one stop, in particular its inner face, is in contact with the adjacent wall of the opening, and such that said fixing hole is positioned at an anchoring depth on said anchoring face of the wall conforming to a given value, then, through said fixing hole of said fixing bracket,The location of the anchor hole to be made in the wall is determined, then this anchor hole is drilled in the wall (in other words, the masonry), then in subsequent steps the fixing device is positioned and fixed to the anchor face of the wall, using a fixing means, said fixing bracket and said fixing angle being assembled together using said holding means and said adjustment means along the longitudinal direction of said fixing bracket, by adjusting the longitudinal position of said angle, then once said two fixing elements are joined together, the frame is fixed to said fixing angle by marking said angle using said at least one stop remaining visible.

[0032] For example, the said means of fixing the fixing bracket to the anchor face of the wall is of the type screw or plug or chemical anchoring suitable for the materials.

[0033] In particular, the longitudinal position of the fixing bracket is adjusted by moving the bracket lengthwise using the markings on the longitudinal strip of the fixing lug. More specifically, the position of the first fixing arm of the bracket, to which the frame will be attached, is adjusted by moving the second arm lengthwise, using the markings on the fixing lug as a guide.

[0034] Advantageously, in the method according to the invention, the frame is fixed to the fixing bracket by marking the bracket with at least one stop, which is still visible. Once the frame is fixed, at least one stop is removed, in particular by breaking off the section that is attached to the stop to remove it from the frame installation.

[0035] Advantageously in the said method, before fixing the frame, a space is reserved for a sealing gasket so that the spacing distance between the anchor face of the wall and the edge of the frame which rests against it is substantially equal to a given thickness of caulking, using a fixing bracket comprising a longitudinal end portion whose thickness is substantially equal to the said given thickness of caulking, the frame being positioned on the said longitudinal portion.

[0036] Furthermore, advantageously, when fixing the frame, the frame is fixed to the fixing bracket according to the height of said first leg of the bracket, in particular by means of fixing holes, distributed according to the extent of said first leg of the fixing bracket, for example by screwing a screw into one of said holes. Advantageously said holes are square in shape.

[0037] Other features and advantages of the invention will become apparent from the following description of particular embodiments of the invention, given by way of example but not limitation, with reference to the attached drawings, for which: [ Fig. 1 ] is a perspective view of a first embodiment of a frame fixing device according to the invention, the two fixing elements constituting the device being shown assembled as they would be arranged when fixing the frame; [ Fig. 2A ] is a perspective view of one of the elements (mounting bracket) of the device illustrated in figure 1 ; Fig. 2B ] is a perspective view of the other element (fixing bracket) of the device illustrated in figure 1 ; Fig. 3 ] schematically illustrates, in partial perspective, the main successive steps of the process of fixing a frame using a fixing device as illustrated in figures 1 And 2A à 2B on a section of the wall receiving the frame; [ Fig. 4A ] is a perspective view of a second embodiment of a frame fixing device according to the invention, the two fixing elements constituting the device being shown assembled as they would be arranged when fixing the frame; [ Fig. 4B ] is a perspective view of one of the elements of the device illustrated in figure 4A ; Fig. 4C ] is a perspective view of the other element of the device illustrated in figure 4A ; Fig. 5 ] schematically illustrates, in partial perspective, the main successive steps of the process of fixing a frame using a fixing device as illustrated in figures 4A à 4C on a section of the wall receiving the frame; [ Fig. 6A ] is a perspective view of a third embodiment of a frame fixing device according to the invention, the two fixing elements constituting the device being shown assembled as they would be arranged when fixing the frame; [ Fig. 6B ] is a perspective view of one of the elements of the device illustrated in figure 6A ; Fig. 6C ] is a perspective view of the other element of the device illustrated in figure 6A ; Fig. 7A ] is a perspective view of a fourth embodiment of a frame fixing device according to the invention, the two fixing elements constituting the device being shown assembled as they would be arranged when fixing the frame; [ Fig. 7B ] is a perspective view from the rear of one of the elements of the device illustrated in figure 7A ; Fig. 7C ] is a perspective view of the other element of the device illustrated in figure 7A ; Fig. 8A ] schematically illustrates, in partial perspective, one of the main steps in the process of fixing a frame using a fixing device as illustrated in figures 7A à 7C on a section of the wall receiving the frame; [ Fig. 8B ] schematically illustrates, in partial perspective, another of the main steps in the process of fixing a frame using a fixing device as illustrated in figures 7A à 7C on a section of the wall receiving the frame; [ Fig. 8C ] schematically illustrates, in partial perspective, another of the main steps in the process of fixing a frame using a fixing device as illustrated in figures 7A à 7C on a section of the wall receiving the frame; [ Fig. 9A ] is a perspective view of one of the elements of another embodiment of a device according to the invention illustrated in figures 9C And 9D ; Fig. 9B ] is a perspective view of the other element of the device illustrated in figures 9C And 9D ; Fig. 9C ] is a perspective view of the sleeper fixing device illustrated in figure 9D , the two fastening elements constituting said device illustrated in figures 9A And 9B being shown during assembly, [ Fig. 9D ] is a perspective view of a sleeper fixing device according to the invention, the two fixing elements constituting said device illustrated in figures 9A And 9B being represented assembled as they would be arranged when the frame was fixed.

[0038] The orientations expressed in the description of the figures are given with reference to a trihedral XYZ frame in which X represents the longitudinal direction of the fixing device for the window frame, Y the transverse direction of the device, and Z the direction perpendicular to said longitudinal and transverse directions of the device, substantially oriented along the height of the device. The XY plane defines the longitudinal plane of the device, and the ZY plane defines the plane perpendicular to said longitudinal plane of the device.

[0039] The longitudinal direction of the device is defined by the longitudinal direction of the fixing bracket, this direction being also substantially parallel to the anchoring face of the wall part to which the fixing device is attached.

[0040] By substantially parallel or perpendicular, we mean a direction / angle that deviates by no more than ±30 degrees, or by no more than 20 degrees or by no more than 10 degrees from a direction that is respectively parallel or perpendicular.

[0041] Identical references can be used from one figure to another to designate identical or similar elements.

[0042] THE figures 1 And 2A à 2B and the figure 3 will be described together.

[0043] THE figures 1A And 2A à 2B represent a first embodiment of a device 1 for fixing a frame according to the invention, the main successive steps of the method of fixing the frame using this device being schematically illustrated in the figure 3 The section of wall defining the frame around an opening in which the door frame is installed is shown on this figure 3 without thermal insulation or any cladding for better clarity of the figures. The figure3 only partially illustrates the fixing of a frame, several fixing devices being distributed around the perimeter of the frame.

[0044] The fastening device 1, according to this first embodiment of the invention illustrated in figures 1 And 2A à 2B , comprises two separate elements that join together: a two-pronged bracket 10, and an adjustment fixing tab 11.

[0045] The bracket 10 comprises a first fixing arm 100 extending along the height of the bracket (direction Z) and a second adjustable arm 101 extending along the longitudinal direction X of the device, the arms thus being arranged substantially perpendicular to each other. It also comprises a lateral reinforcing wall 102 extending between the two arms in the ZX plane. The first fixing arm 100 comprises a set of fixing holes 1000 facilitating the attachment of additional fixing means, to allow the frame to be fixed either surface-mounted or recessed using said additional fixing means such as one or more screws. Opposite the reinforcing wall 102, the second arm 101 comprises a lateral portion 1010 for fixing to the masonry and cooperating with the adjustable fixing bracket 11 to secure the two fixing elements together in an adjustable manner.The lateral fixing part 1010 includes an adjustment slot 1011 along the longitudinal direction of the device (X). This lateral fixing part 1010 also includes a set of projecting lateral ridges 1012, arranged symmetrically in pairs on each side of the adjustment slot 1011, forming means for retaining and adjusting the two fixing elements 10, 11 during the longitudinal adjustment of the device.

[0046] The generally elongated adjustment bracket 11 extends in its principal direction along the longitudinal direction X, which defines the longitudinal direction of the device, its average plane extending along the XY plane of the fixing device. It comprises a central plate 110 with a fixing hole 1101 surrounded by a lip 1102 projecting from the outer face of the plate, that is, from the face opposite the inner face, which will be directed towards the masonry into which the bracket will be fixed.On this outer face are longitudinally marked (direction X) graduations 1110, made according to the example by different notches with the mention of numbers, in millimeters according to the example, indicating different depths of adjustment, according to the longitudinal direction X, for the correct positioning of the fixing arm 100 of the bracket 10, adapted to the fixing of the frame with said fixing device, as will be explained in more detail in the comments of the. figure 3 . These graduations are carried along longitudinal strips 1111, 1112 which laterally border said central plate 10.

[0047] The term "leg having an overall elongated shape" means that the main direction of said fixing leg extends along its longitudinal direction.

[0048] The said fixing bracket 11 also includes lateral retaining and adjustment grooves 111 present transversely along the entire length of the said strips 1111, 1112 which laterally border the said plate, these said grooves forming a relief by alternating hollows and bumps on the inner face of the strips, this face bearing against the outer face of the said lateral fixing portion 1010 of the bracket 10 to cooperate with the said reliefs 1012, when the said fixing bracket and bracket are assembled in an adjustable longitudinal manner to form the said fixing device, as illustrated in the figure 1 The said set of lateral support and adjustment lugs 1012 of the said lateral fixing part 1010 of the bracket 10 cooperates with the said lateral grooves 111 of the said fixing bracket 11 to adjust the longitudinal position (direction X) of the said fixing bracket 10, in particular of its first arm 100 to which the frame will be fixed, so as to adapt the device to the thickness of the frame to be fixed, as will be explained in more detail in the comments of the figure 3 . These reliefs and grooves also allow, by compression, to properly hold the two fixing elements 10, 11 together, preventing slippage, when their assembly is adjusted longitudinally and when they are joined together.

[0049] These respective means of holding and adjusting said elements cooperate with each other to allow the bracket to be moved longitudinally by guiding it and keeping it in contact with the fixing bracket.

[0050] The free end of each strip 1111, 1112 is curved so that each curved end forms a support stop whose inner face will bear against the masonry, i.e., against a face of the opening. As indicated above, the anchoring depth of the fixing device to the wall's anchoring face, relative to the opening, is a predefined dimension, required, for example, by regulations. The fixing bracket is thus designed to serve as a template to aid in installing the device, the distance along the longitudinal direction X of the bracket between a virtual axis passing through the center point of the exit hole of said fixing hole 1101 of the bracket and the inner face of each stop 1111, 1112 comprising said bracket being substantially equal to this required anchoring distance. The inner face of a stop is defined as the face of the stop that will be turned towards the wall's anchoring face when the fixing device is installed.A portion of each strip ending with a said stop 1111, 1112 is breakable in order to be able to remove this part of said leg after the installation of the frame.

[0051] In addition, the thickness of said strips 1111, 1112 is adapted to the required caulking thickness (along the Z direction) to be reserved for a sealing gasket between the wall anchor face and the frame.

[0052] There figure 3 schematically shows the different stages of installation of a frame upright D on a part of wall M, using said fixing device 1, without representation of the thermal insulation or the possible facing for better clarity of the figure.

[0053] Initially, the fixing bracket 11 is used alone as a template, by positioning it on the anchoring face M0 of the wall covered with a layer of insulation and a facing not shown in the figure. The said fixing bracket 11 is arranged by placing the inner face of each stop 1111, 1112 which is formed by the curved end of each lateral strip against the adjacent face M1 of the table, so that the center of the orifice opening from the fixing hole 1101 is on the anchoring face M0 at a given anchoring depth "d", for example a thickness required by a regulation substantially equal to 60 mm, and the location into which the center of the fixing hole 1101 of said bracket 11 opens is located by making a mark on said anchoring face M0 of the wall, for example with a pointed tool T, by passing this tool through the fixing hole 1101 of said bracket 11.Next, remove the fixing bracket 11 and drill an anchor hole at the marked location in the masonry. Alternatively, drill directly, for example, by passing the drill bit through the fixing hole 1101 of the bracket that remains in place. Then, place the fixing bracket 10 onto the anchor face M0 of the wall, with the oblong fixing slot 1011 aligned with the marked location just created. Finally, place the fixing bracket 11 onto the lateral fixing portion 1010 of the bracket. A fixing screw V can then be loosely screwed into the masonry by passing both the anchor and the screw through the fixing hole 1101 of the bracket 11 and the oblong slot 1011 of the bracket to secure these two elements 10 and 11 together and within the masonry.Next, the longitudinal position (X direction) of the bracket 10 is adjusted by moving it along the travel allowed by the oblong slot 1011, so that the receiving face of the frame of the first arm 100, which has pilot holes 1000 for fixing the frame upright, is correctly positioned longitudinally to receive this upright, taking into account the available space due to the insulation layer and the facing remaining in place on the wall. Once the bracket is positioned correctly, its fixing is completed by tightening the screw V into the masonry. The partially shown frame is positioned flush with the masonry reveal, in contact with the longitudinal strips 1111, 1112, to ensure the minimum thickness for housing the sealing gasket J for caulking.The fixed frame is then fixed by its internal rebate to said first arm 100 of the bracket 10, using at least one screw V', for example a self-drilling screw with a clip groove, by inserting said screw V' into a hole provided on the fixed frame to screw it into one of the fixing holes 1000 of said arm 100.

[0054] The said graduations on the strips 1111, 1112 of the fixing bracket 11 of said fixing device 1 allow the position of the device to be adjusted according to the longitudinal direction X, and more particularly that of the receiving arm 100 of the frame of the bracket 10, and similarly for the plurality of fixing devices 1 necessary for fixing one side of the frame, and more generally for all the fixing devices 1 distributed around the perimeter of the frame, taking into account the thickness of the frame.

[0055] The said device allows the position of the fixing device to be adjusted to each situation, that is to say that the same fixing device is used for different installations of joinery frames for a given building, or different buildings to be renovated.

[0056] THE figures 4A à 4C and the figure 5 will be described together.

[0057] THE figures 4A à 4C represent a second embodiment of a device for fixing a frame according to the invention, the main successive steps of the method of fixing the frame using this device being schematically illustrated in the figure 5 The section of wall defining an opening in which the frame is installed is shown on the figure 5 without thermal insulation or any facing for better clarity of the figure.

[0058] The fixing device 2, according to this second embodiment of the invention, comprises, as for the first embodiment, two separate elements that are joined together: an adjustable fixing bracket 20 with two arms, and an adjustment fixing tab 21.

[0059] The bracket 20 comprises a first arm 200 extending along the height of the bracket (direction Z), in the ZY plane, and a second arm 201 extending along the longitudinal direction X of the device, in the XY plane, the arms thus being arranged perpendicular to each other. The bracket further comprises a lateral reinforcing wall 202 arranged between the two arms, in the XZ plane. The first arm 200 comprises a set of fixing holes 2000 for fixing the bracket to the frame using additional fixing means such as screws. The second arm 201 comprises an adjustment recess 2010, elongated in shape along the longitudinal direction X of the device, opening to form a notch in the bottom of the fixing arm 20, allowing the assembly by interlocking of a portion of the fixing bracket 21.

[0060] The adjustment fixing bracket 21 comprises a fixing portion drilled with a fixing hole 2100 for fixing to the anchoring face of the wall and an adjustment portion including a longitudinal strip 211. The strip 211 includes a stop 2112 at its free end, the stop being the termination of a breakable portion 2111 at the end of the strip, made breakable by a thinning of material and a break 21110. As explained for the first embodiment, the stop ensures that the anchoring depth of the fixing device to the masonry is at the required distance, the fixing bracket serving as a template for installing the device, the distance along the longitudinal direction X of the bracket between a virtual axis passing through the center point of the fixing hole of the bracket and the inner face of the stop comprising the bracket being equal to this required distance.The said ruler has graduations 2110 on its outer face, made according to the example by different lateral notches with the mention of numbers, in millimeters according to the example, indicating different longitudinal adjustment positions of the fixing arm 200 of the bracket 20 useful when fixing the frame with said fixing device, as will be explained in more detail in the comment of the. figure 5 . During the assembly of the two fixing elements 20, 21, said strip 211 is positioned under the bracket 20, to fit into the recess 2010 of the bracket 20 and allow the longitudinal adjustment of the position of said bracket 20.

[0061] There figure 5 This schematically illustrates, from left to right when viewing the figure, the main steps involved in installing a frame stud D onto a section of wall M, using the aforementioned fixing device 2. The procedure is quite similar to that described in the comments of the figure 3 . Initially, the fixing bracket 21 is used alone as a template, by positioning it on the anchoring face M0 of said part of the wall, to which said device will be fixed, covered with insulation and facing (not shown). The said fixing bracket 21 is positioned in the insulation, in an area which has been hollowed out by removing some insulation material, and so that the stop 2112 of the strip 211 is in contact with the adjacent wall of the table M1 (wall substantially perpendicular to said wall anchoring face), and so that the fixing hole 2100 in the masonry is at the required anchoring depth (distance "d"), and the location of the anchoring hole to be made in the masonry is located by marking a reference point on said wall anchoring face, for example with a pointed tool T, by passing this tool through the fixing hole 2100 of said bracket 21.Alternatively, one can drill directly, for example, by passing the drill bit through the fixing hole 2100 of the bracket that remains in place. Once the anchor hole is drilled in the masonry, the fixing bracket 20 is positioned under the fixing bracket 21 so that the sliding strip 211 fits into the recess 2010 opened under the second arm 201 of the bracket. The longitudinal position (along the X direction) of the bracket is adjusted using the graduations 2110 on the sliding strip 211, according to which the part with the recess 2010 of the second longitudinal arm 201 of the bracket is moved. The device 2 is fixed to the masonry by inserting a wall plug and screwing a screw V through the fixing hole 2100 of the fixing bracket 21.

[0062] The partially shown fixed frame is positioned at the right of the masonry panel in contact with the longitudinal strip 211 in order to ensure the minimum caulking thickness required for the sealing gasket J.

[0063] The bracket's position is located behind the frame jamb D using the still-visible stop, and the frame is then fixed to the bracket in at least one of the pre-drilled fixing holes 2000 in the first arm 200 of the bracket, for example, by drilling through the frame with at least one self-drilling screw V' and screwing the screw into one of the pre-drilled holes 2000 in the first arm 200 of the bracket. Alternatively, a retaining wedge B, inserted into a groove in the frame jamb, can be used.

[0064] At the end of the installation of the frame, the stop is removed by breaking off the breakable portion at the end of the strip.

[0065] THE figures 6A à 6C represent a third embodiment of a device 3 for fixing a sleeper according to the invention, said device comprising two separate elements that are joined together: a fixing bracket 30 with two arms, and an adjustment fixing tab 31.

[0066] The bracket 30 comprises a first arm 300 extending along the height of the bracket (direction Z), in the ZY plane, and a second arm 301 extending along the longitudinal direction X of the device, in the XY plane, the arms thus being arranged substantially perpendicular to each other. The bracket 30 further comprises a central reinforcing wall 302 disposed between the two arms, extending in the XZ plane. The first arm 300 is flat with a chamfered lower corner and includes a set of fixing holes 3000 for attaching the frame using additional fasteners such as screws. The second arm 301 is generally cylindrical in shape, its principal axial direction being oriented along the longitudinal direction X, and allows assembly by interlocking and quarter-turn locking with a portion 312 of the fixing bracket 31.It includes on the surface retaining and adjustment notches 3010, oriented transversely (Y direction) to the main axial direction of said cylinder.

[0067] The adjustment bracket 31 comprises an adjustment portion and a lateral fixing block. The lateral fixing block 310 includes a fixing hole 3101 for attaching the fixing device 3 to the masonry. The adjustment portion comprises a hollow cylindrical body 3112 into which the second cylindrical arm 301 of the bracket is inserted when the two elements 30 and 31 are assembled. The adjustment portion includes a longitudinal strip 311 (direction X). The strip 311 has graduations 3110 on its outer face, marked, as shown in the example, by various transverse notches with numbers, in millimeters as shown in the example, indicating the longitudinal adjustment depths of the fixing device, and particularly useful for positioning the fixing arm 300 of the bracket for attaching the frame to the fixing device.The strip 311 includes a stop 3112 at its free end, said stop being attached to a breakable portion 3111 at the end of the strip. As explained for the embodiments described previously, this stop allows the fixing bracket to be used as a template to fix the fixing device to the masonry according to the required anchoring depth. During the assembly of the two fixing elements 30, 31, the second cylindrical arm 301 of the bracket 30 is inserted into the hollow body 3112 of said bracket, where it is held by the retaining and adjusting notches 3010 cooperating with complementary notches inside said hollow body 3112 of the bracket, by means of a quarter-turn locking mechanism, and said bracket 30 is positioned on the strip 311, under the beveled corner of the first arm 300.Previously, the longitudinal position (direction X) of the fixing bracket, more particularly the position of the fixing arm 300 along the longitudinal direction X to fix the frame, was adjusted by longitudinally translating said second arm 301 in said hollow body 312 of the leg 31, by reference according to the graduations of said ruler 311.

[0068] The method of fixing a frame upright using this third method of fixing device 3 is not illustrated, but it is understood that it takes place similarly to the methods of the previous methods which have been illustrated or of the one which will be illustrated for a fourth embodiment, the fixing bracket 31 serving as a template to locate the anchoring point of said device on the anchoring face of the masonry according to the required anchoring depth, and to make the reservation for the sealing gasket according to the required caulking thickness.

[0069] THE figures 7A à 7C represent a fourth embodiment of a device 4 for fixing a sleeper according to the invention, said device comprising two separate fixing elements that are joined together: an adjustable bracket 40 with two arms, and an adjustment fixing tab 41.

[0070] The bracket 40 comprises a first arm 400 extending along the height of the bracket (direction Z), in the ZY plane, and a second arm 401 extending along the longitudinal direction, arranged substantially perpendicular to each other, as well as a central reinforcing wall 402 arranged between the two arms 400 and 401, in the ZX plane, and lateral reinforcements 403 and 404 between the two arms substantially in the XY plane. The first arm 400, for fixing the frame, is flat with a beveled lower corner, and includes a set of fixing holes 4000 to allow the frame to be fixed using additional fixing means such as screws.The second arm 401 is generally semi-cylindrical in shape, its main axis extending along the longitudinal direction X, internally hollowed, and comprising on its internal surface retaining and adjustment notches 4010, oriented transversely to the main axial direction of the half-cylinder. The arm, i.e., the half-cylinder, comprises an open longitudinal base including two internal longitudinal projections 4011, 4012, forming internal flanges oriented along the main axial direction of the half-cylinder. The notches 4010 and the flanges 4011, 4012 allow the bracket to be assembled by a quarter-turn interlocking mechanism with a portion 412 of the mounting bracket 41.

[0071] The adjustment bracket 41 comprises a central fixing block 410, on either side of which extend longitudinally a first adjustment portion 411 and a second adjustment portion 412. The fixing block 410 includes a fixing hole 4101 for attaching the bracket, and thus the fixing device 4, to the wall anchoring face. The first adjustment portion consists of a longitudinal strip 411 bearing graduation marks 4110 on its outer face, formed, as shown in the example, by various lateral notches marked with numbers, in millimeters as shown in the example, which allow adjustment of the longitudinal position of the bracket. The strip 411 terminates at its free end with an adjustment stop 4112.As explained for the embodiments described above, this stop allows the fixing bracket to be used as a template to fix the fixing device to the masonry anchor face according to the required anchoring depth. The stop 4112 terminates a breakable longitudinal portion 4111 at the end of the strip, which can thus be detached. The second adjustment portion 412 comprises a partially cylindrical body having retaining and adjustment notches 4122 adapted to cooperate with the internal notches 4010 of the second arm 401 of the bracket 40. The body further comprises a lateral slot 4120 into which the larger lip 4012 of the second arm 401 of the bracket is inserted, these elements forming locking and unlocking means for the quarter-turn type fixing device.It further includes a lateral notch 4121 cooperating with the other edge 4011 of the second arm 401 of the bracket, aiding in retaining the bracket on the leg, particularly during adjustments. The two fixing elements 40, 41 are assembled and secured together by fitting the semi-cylindrical arm 403 of the bracket 40 around the cylindrical body of the leg 41, and in an adjustable longitudinal manner (X direction), the internal notches 4010 of the longitudinal arm 401 of the bracket engaging in the notches 4122 of the leg. Thanks to the graduations 4110 on the strip 411, the longitudinal position of the first arm 400 of the bracket is determined, in order to adapt the device, in particular, to the thickness of the frame that will be fixed to the bracket.The locking and unlocking of the bracket to said leg to achieve the longitudinal adjustment of the bracket on said leg is done by rotating said leg 40 a quarter turn around the cylindrical body of said leg 41.

[0072] As illustrated in figures 8A à 8C The wall delimiting the opening receiving the joinery to be installed includes the masonry anchoring face M0 of the wall M, to which the joinery frame is fixed, generally of the type known as structural, and at least one layer of thermal insulation C (and where applicable also sound insulation), this layer being itself covered with a facing P such as for example a panel consisting of a core made of plaster.

[0073] In a first step, the fixing bracket 41 alone is used as a template, so that the anchor point of said fixing bracket on the wall anchor face M0 is at the required anchoring depth "d" relative to the frame (face M1). The adjusting fixing bracket 41 is thus positioned in the insulation layer C, in an area that has been devoid of insulating material, and so that its stop 4112, on its inner face, rests against the adjacent wall M1 of the frame. An anchor hole is drilled in the masonry, for example with a drill-driver S, by passing the drill bit mounted on the drill through the fixing hole 4101 of said bracket ( figure 8A ). The fixing bracket 41 is then fixed by inserting a wall plug into the anchor hole that has just been made in the masonry, and then screwing a screw through the fixing hole of the bracket. Next, the fixing bracket 40 is secured to the fixing bracket 41 by fitting the second arm 401 of the bracket 40 around the partially cylindrical body of the second adjustment part 412 of the fixing bracket 41, as explained above, by adjusting the longitudinal position (X direction) of the bracket 40 using the graduations 4110 on the ruler ( Fig. 8B ). A sealing strip J can be applied in the space provided, according to the thickness of the longitudinal portion at the end of the strip. The frame D is then fixed by application to the first arm 400 of the bracket 40, which includes the pre-drilled holes 4000, for example by inserting a self-drilling screw V' from the outer face of the frame and by reference using the stop 4112, which is still visible, aligned with the stop 4112 of the fixing bracket 41 ( Fig. 8C ). Once the frame has been installed, the said breakable portion 4111 with the said stop 4112 is then removed.

[0074] THE figures 9A à 9D represent another embodiment of a device for fixing a sleeper according to the invention, quite similar in its assembly to that described with reference to figures 7A à 7C .

[0075] Said device 5 comprising two separate fixing elements that are joined together: an adjustable bracket 50 with two arms, and an adjustment fixing tab 51.

[0076] The bracket 50 comprises a first arm 500 extending along the height of the bracket in the YZ plane, and a second arm 501 extending along the longitudinal direction X, arranged substantially perpendicular to each other, as well as a central reinforcing wall 502 arranged in the ZX plane between the two arms 500, 501. It also comprises lateral reinforcements 504, 505, and other lateral reinforcements 506, 507 substantially horizontal extending in the XY plane between the wall 502 and the vertical arm 500. The first arm 500 for fixing the frame is flat and includes a set of fixing holes 5000 which allow the frame to be fixed to it using additional fixing means such as screws.The said fixing holes are advantageously square through holes, a shape well suited to receiving the screws, particularly when fixing the frame which is done "blindly" thanks to the identification of the device by the end of the fixing tab 51, similarly to what is explained above with reference to the . figures 8A à 8C .

[0077] The second arm 501 of the bracket 50 is generally semi-cylindrical in shape, its principal axis extending along the longitudinal direction X. It is internally hollow and includes, on its upper internal surface, retaining and adjustment notches 5010, oriented transversely to the principal axial direction of the half-cylinder. The arm, i.e., the half-cylinder, comprises an open longitudinal base with two internal projecting portions 5011 and 5012, forming transverse internal flanges oriented longitudinally along the principal axial direction of the half-cylinder. One of the flanges 5012 forms the larger flange because it is slightly wider than the other, and it terminates in a return 50120 with a substantially vertical orientation. The said notches 5010 and the said edges 5011, 5012 allow the assembly of the bracket by interlocking, of the quarter-turn type, with an adjustment part 512 of the fixing tab 51.

[0078] The said adjustment fixing bracket 51 includes a central fixing block 510, on either side of which extend longitudinally a first adjustment part 511 and a second adjustment part 512. The said fixing block 510 includes a fixing hole 5101 for fixing the said bracket to the wall, and therefore the said fixing device 5 to the anchoring face of the wall.

[0079] The first adjustment portion 511 comprises a longitudinal strip 5111 bearing markings 5110, in the form of graduations, on its upper outer face, made according to the example with the indication of numbers, in millimeters according to the example, which will allow the longitudinal position of the bracket 51 to be adjusted. The first adjustment portion 511 terminates at its free end with an adjustment stop 5112. As explained for the embodiments described previously, this stop 5112 allows the fixing bracket 51 to be used as a template in order to fix the fixing device 5 to the anchoring face of the masonry according to a given anchoring depth. The said stop 5112 comes at the end of the said first adjustment part 511, then of the strip 5111 and of a curved portion 5114. According to the example, the whole of the said first adjustment part 511 constitutes a separable longitudinal portion of the device 5.It can thus be detached at the notch 51110, at the end of the installation of the frame, the strip 5111 thus detaching entirely with the curved end portions 5114 and stop 512. Said curved portion 5114, which comprises said first adjustment part 511, is located between the longitudinal strip 5111 and the stop 512, and has a curvature turned outwards and which extends beyond the level of the stop 5112. This curved portion 5114, when said fixing bracket 51 or the entire device 5 are installed, makes it possible to create a space between the wall and said adjustment part 511 which facilitates the gripping of said bracket by an operator. The operator can pass one or more fingers into this space to grasp the end of said tab 51. This makes it easier to manipulate said tab, and to more easily detach the breakable part, i.e. according to the example the adjustment part 511, at the end of the installation of the frame.

[0080] The second adjustment part 512 comprises a partially cylindrical body having retaining and adjustment notches 5122 adapted to cooperate with the internal notches 5010 of the second arm 501 of the bracket 50. The body further comprises a lateral slot 5120 into which the larger rim 5012 of the second arm 501 of the bracket is inserted, these elements forming locking and unlocking means for the quarter-turn fastening device. It further comprises a lateral notch 5121 cooperating with the other rim 5011 of the second arm 501 of the bracket, assisting in retaining the bracket on the leg, particularly during adjustments.

[0081] With reference in particular to figures 9C And 9DThe two fixing elements 50, 51 are assembled and secured together by fitting the semi-cylindrical arm 501 of the bracket 50 around the cylindrical body of the leg 51, and in an adjustable longitudinal manner (direction X) according to arrow F, the internal notches 5010 of the longitudinal arm 501 of the bracket fitting into the notches 5122 of the leg. Thanks to the graduations 5110 on the strip 5111, the longitudinal position of the first arm 500 of the bracket is determined, in order to adapt the device, in particular, to the thickness of the frame that will be fixed to the bracket 50. As illustrated in figure 9C , the locking and unlocking of the bracket 50 to said leg 51 to achieve the securing and longitudinal adjustment of the bracket on said leg, is done by rotating said bracket 50 around the cylindrical body of said leg 51 by a quarter turn (arrow R).

[0082] For the various fixing devices according to the invention just described, the end strips or longitudinal portions bearing the stop, the fixing brackets can advantageously be made with a thickness that allows for compliance with a given, or even regulation-required, sealing thickness for a gasket, between the edge of the frame and the bearing face (M0 anchor face) of the wall on which said edge rests. This minimum dimension required for the gasket is, for example, 5 mm.

[0083] The various components of the fastening devices according to the invention, as described above, are advantageously made of a plastic material with thermally insulating properties, thus preventing the introduction of thermal bridges within the insulation layer around the renovated window or door frame. This material may also include reinforcing elements such as fiberglass.

[0084] The invention provides an economical fixing device for a window or door frame, particularly one that reduces labor costs during installation and fixing, especially during complete renovation by removal of the existing frame. This device facilitates adjustments to accommodate the presence of insulation and any cladding, as well as the thickness of the frame being fixed. The device allows for easy anchoring of the fixing device at the desired anchoring depth (in the longitudinal direction X) and maintains this position during frame fixing. Furthermore, the position of the part of the device dedicated to fixing the frame is longitudinally adjustable from this anchoring position of the device's fixing bracket. The invention provides fixing devices adaptable to various wall configurations with insulation, once the fixing bracket has been positioned at the required anchoring depth relative to the wall opening.

[0085] Secondly, the invention also makes it possible to provide a fastening device that eliminates, or at least significantly reduces, the thermal bridges created by prior art fastening devices.
