Description

Technical Field

[0001] The present invention relates to a mounting bracket for installing a first building component in a second building component, the mounting bracket comprising a first bracket leg extending in a first leg plane, the first leg plane extending in a first dimension and a third dimension perpendicular to the first dimension.

[0002] A second bracket leg extends from the first bracket leg in a second dimension perpendicular to the first dimension and third dimension, wherein the first bracket leg adjoins the second bracket leg in a bend.

[0003] The second bracket leg comprises at least a first opening centred in an associated first plane and a second opening centred in an associated second plane and each providing a through-hole from a first side of the second bracket leg to a second side of the second bracket leg, wherein each of the planes are arranged perpendicularly to the first leg plane.

[0004] The at least two openings of the second bracket leg are configured for receiving a fastening means, such as a screw, from the first side to the second side of the second bracket leg.

[0005] The invention furthermore relates to a roof window comprising a set of mounting brackets, and a method of mounting a mounting bracket.Background Art

[0006] Installation of building components such as roof windows into other building components such as a roof structure traditionally takes place by means of fittings in the form of mounting brackets fastened to the frame of the window and to the roof structure in which the roof window is to be built in.

[0007] Examples of prior art mounting brackets are shown and described in Applicant's EP 4 187 037 A1, in which a roof window is installed by means of two sets of mounting brackets. Depending on the installation height of the roof window in the roof structure, i.e. standard or recessed, the mounting brackets are positioned differently on the frame of the roof window. While several efforts have been made to facilitate the installation process including fastening of the mounting brackets to the frame and to the roof structure, there is still room for improvement.Summary of Invention

[0008] With this background it is an object of the present invention to provide a mounting bracket which is designed to facilitate the installation process even further.

[0009] In a first aspect, this and further objects are achieved with a mounting bracket of the kind mentioned in the introduction, which is further characterised in that the first bracket leg comprises a set of apertures comprising a first aperture and a second aperture, each centred in one of the respective associated planes and each configured for providing visual access to the respective at least one opening of the second bracket leg.

[0010] By the provision of apertures in the first bracket leg which are dedicated to providing visual access to the openings in the second bracket leg, substantial ease of installation is achieved since the installer has means for visual guidance when inserting the screws into the respective opening in the second bracket leg and further into the building component such as a frame member of a roof window. From a normal working position of the person performing the installation, the field of view would otherwise have been blocked by the first bracket leg itself, and direct visual access would have required bending down, kneeling or assuming other disadvantageous working positions. Since the visual access apertures are dedicated to only being able to be looked through, they are not configured so as to be used as holes for receiving fastening means.

[0011] In some embodiments, the bend extends along the third dimension, and the second bracket leg extends in the third dimension and the second dimension. The planes in which apertures are arranged may extend in the first dimension and the second dimension.

[0012] The first plane may alternatively be perpendicular to the second plane.

[0013] The second bracket leg may comprise a first bracket section and a second bracket section. The first bracket section may extend in the first dimension and the second dimension. The second bracket section may extend in the second dimension and the third dimension.

[0014] The first aperture may be arranged in the first bracket section.

[0015] The second aperture may be arranged in the second bracket section.

[0016] Alternatively, the first and second apertures are both arranged in either the first or second bracket section.

[0017] The first section and a second section may be separated and may individually extend from the first leg.

[0018] The first section, second section and first bracket leg may meet in a corner edge.

[0019] The visual apertures may be especially advantageous in mounting brackets comprising a second bracket leg with bracket leg sections extending in different planes because this can obstruct the viewing angles even further.

[0020] The first bracket leg may have a longest length extension in the third dimension between a first bracket side and a second bracket side, wherein the mounting bracket has a centre plane extending in the first dimension and second dimension, where said centre plane is arranged centrally between the first bracket side and the second bracket side.

[0021] Each visual aperture of the set of visual apertures may be arranged closer to the centre plane than to any one of the first and second bracket sides. The visual apertures are especially advantageous when the openings for fastening means are arranged closer to the centre plane of the mounting bracket than to the bracket sides, because such brackets require a sharp viewing angle to have a direct line of sight beyond the first bracket leg to the opening.

[0022] Each of the first plane and second plane may be arranged closer to the centre plane than to any one of the first and second bracket sides.

[0023] The length extension of the first leg in the third dimension may be at least equal to the length extension of the first leg in the first dimension. Preferably, the length extension of the first leg in the third dimension is larger than the length extension of the first leg in the first dimension.

[0024] The visual apertures are especially advantageous for mounting brackets where the mounting bracket has a length extension in third dimensions that at least equals the length extension in first dimension, since the first leg in such brackets are especially prone to block the usual viewing angles for the installer. This is especially true if the opening configured for receiving fastening means is arranged closer to the centre plane than to any one of the first and second bracket sides.

[0025] Each visual aperture of the first bracket leg may be formed as an oblong aperture. The oblong aperture has the advantage of providing better visual access to the opening for fastening means under normal installation condition i.e. installing the bracket with a normal viewing angle with the installer being in a normal working position. Additionally, it allows the installer to take slightly different positions with different viewing angles and still see the opening.

[0026] The length extension of each visual aperture in the first dimension may be larger than the length extension of the associated opening in the second bracket leg in the second dimension. This has the advantage that the installer can observe the entire length of the opening for fastening means through the visual opening.

[0027] Alternatively, the first aperture may be longest in the third dimension and the second aperture may be longest in the first dimension. This is especially advantageous in embodiments where the first and second planes are arranged perpendicular to each other.

[0028] Each aperture of the first bracket leg may have a width extension in the third dimension at least the width of the associated opening in the third dimension. Alternatively, the width extension of each visual aperture may be larger than the width extension of the associated opening in the third dimension. This has the advantage of providing better visual access to the opening for receiving fastening means as well as to the most proximal surroundings of that opening, making it easier to navigate a fastening means towards the opening and allowing the installer to take slightly different viewing angles and still see the entire opening.

[0029] The dimensions of at least one of the apertures of the first bracket leg may be selected such that the length extension in the first dimension of the aperture is larger than the width extension in the third dimension by a factor in the range of 2 to 10, preferably in the range of 3 to 6.

[0030] The dimensions of at least one of the apertures of the first bracket leg may be selected such that the length extension in the first dimension is larger than the length extension of the associated opening in the second dimension.

[0031] The opening may be a circular opening. Alternatively, the opening may be an oblong opening. The opening may have a length extension in the second dimension which exceeds the length extension in the third dimension.

[0032] The set of apertures may comprise a first aperture and a second aperture in the first bracket leg, preferably located substantially equidistantly from the centre plane as seen in the third dimension, wherein the associated planes are substantially parallel. Preferably, each aperture is arranged with a distance to the centre plane.

[0033] The visual apertures may be arranged equidistantly to the centre plane. Additionally, the visual apertures may be arranged with an offset to the centre plane.

[0034] An end edge of each aperture as seen in the first dimension may be located at a distance from the bend not exceeding the width extension of the aperture in the third dimension.

[0035] The set of openings in the second bracket leg comprises a first opening opposite the first aperture in the first bracket leg. The first opening and the first aperture are arranged in the same first plane.

[0036] The mounting bracket further comprises a second opening opposite the second aperture. The second aperture and the second opening are arranged in the same second plane.

[0037] The mounting bracket may comprise a third opening arranged above or below the first opening as seen in the second dimension.

[0038] The mounting bracket may comprise a fourth opening arrange above or below the second opening as seen in the second dimension.

[0039] The mounting bracket may comprise a second set of visual apertures in the second bracket leg.

[0040] Each aperture comprised in the second set of apertures may each be centred in one of the first and second planes.

[0041] The first bracket leg may comprise at least one opening for receiving fastening means. Each of the at least one openings in the first bracket leg may be aligned with an aperture comprised in the second bracket leg.

[0042] The first bracket leg and the second bracket leg may be mirror-images of each other i.e. the first bracket leg and second bracket leg may have equal length extensions in the first, second, and third dimensions. This has the advantage that the first bracket leg may function as the second bracket leg and vice versa providing a more versatile mounting bracket.

[0043] The first bracket leg may have a longest length extension in the third dimension between a first bracket side and a second bracket side, wherein the distance from the one opening to the bend is shorter than the distance from the opening to any one of the first and second bracket side.

[0044] In a second aspect this and further objects are achieved with a roof window comprising a set mounting brackets according to the first aspect.

[0045] In a third aspect this and further objects are achieved with a method of mounting a mounting bracket according to the first aspect, comprising the steps of arranging the second side of the second bracket leg on the first building component, attaching the mounting bracket to the first building component by inserting a fastener into the first opening from the first side of the second bracket leg while visually observing the first opening and the fastener through the first aperture.

[0046] The method may further comprise the step of inserting a fastener into the second opening from the first side of the second bracket leg while visually observing the second opening through the second aperture.

[0047] A feature described in relation to one of the aspects may also be incorporated in the other aspect, and the advantage of the feature is applicable to all aspects in which it is incorporated.

[0048] Other presently preferred embodiments and further advantages will be apparent from the subsequent detailed description and drawings.Brief Description of Drawings

Description of Embodiments

[0050] In the following detailed description, preferred embodiments of the present invention will be described. However, it is to be understood that features of the different embodiments are exchangeable between the embodiments and may be combined in different ways, unless anything else is specifically indicated. It may also be noted that, for the sake of clarity, the dimensions of certain components illustrated in the drawings may differ from the corresponding dimensions in real-life implementations.

[0051] It is noted that terms such as "up", "down", "left-hand", "right-hand", "exterior", "interior", "outer", "inner" are relative and refers to the viewpoint in question. In general, when referred to an exterior side, this relates to a side of a roof window in the mounted condition facing the outdoors or external side of the building.

[0052] Referring initially to Fig. 1, a roof window 1 is shown. In the initial general description, the shown roof window is representative of an embodiment of the invention and of the prior art as shown and described in Applicant's EP 4 187 037 A1, in the embodiment shown in Fig. 3 of the EP document. Only details of relevance are shown and will be described in detail. Elements having the same or analogous function as in the present invention are denoted by the same reference numerals as will be referred to in the description of embodiments of the invention.

[0053] In Fig. 1, a first building component 1 in form of a roof window 1 is installed in a second building component 100 in the form of a roof structure 100 of an inclined roof surface (not shown). The roof window comprises a frame 2. The frame 2 comprises a set of frame members including a top frame member (not shown), two side frame members 22 and a bottom frame member 24. Further elements of the roof window 1 may include a sash with a pane, connected to the frame 2 by means of a set of hinges 5. The roof structure 100 is represented by a number of rafters of which one rafter 101 is shown, on top of which battens 102, 103 are shown as well as an auxiliary batten 104. A first set of four prior art mounting brackets 6 is provided and connected to the frame 2, near the corners of juxtaposed frame side members and frame top / bottom member, here to the bottom frame member 24 resting on auxiliary batten 104. A second set of mounting brackets 7 is provided, here connected to the side frame member 22 near the position of the hinge 5. In case the roof window 1 is intended to be installed at a lower installation level than the one shown in Fig. 1, the mounting bracket 6 of the first set would instead be connected to the side frame member 22, at a higher level of the frame 2, and resting on the rafter 101 while the mounting bracket 7 of the second set would be turned such that its second leg points downwards.

[0054] Fig. 2A shows an embodiment of a mounting bracket 10 according to the invention.

[0055] The mounting bracket 10 has a first bracket leg 11 extending in a first dimension 1D and a second bracket leg 12 extending from the first bracket leg 11 in a second dimension 2D perpendicular to the first dimension 1D. The first bracket leg 11 adjoins the second bracket leg 12 in a bend 13 extending along a third dimension 3D perpendicular to the first dimension 1D and the second dimension 2D. The first bracket leg 11 therefore extends in a first leg plane FLP which is defined by the first dimension 1D and the third dimension 3D. In the shown embodiment, the second bracket leg 12 extends in the second dimension 2D and the third dimension 3D.

[0056] The second bracket leg 12 has two openings 123i, 124i each centred in one of two respective planes P1, P2. Each opening 123i, 124i provides a through-hole from a first side of the second bracket leg 1201 to a second side of the second bracket leg 1202 as seen in the first dimension 1D.

[0057] Each of the openings 123i and 124i are configured for receiving a fastening means, such as a screw, from the first side to the second side of the second bracket leg 12.

[0058] The first bracket leg 11 has a set of apertures 111, 112 each centred in one of the respective associated first plane P1 and second plane P2. Each aperture is configured for providing visual access to one of the openings 123i, 124i of the second bracket leg 12, as best seen in Fig. 2B, where the alignment of the apertures 111, 112 and openings 123i, 124i in the planes P1, P2 provide visual access to the openings from a position an installer typically takes when installing a mounting bracket. The perspective shown in Fig. 2B shows a normal viewing angle for an installer in a normal working position. The mounting bracket may have to be installed in a tight space without the possibility to observe the openings 123i, 124i by looking underneath or around the sides of the first bracket leg 11. Each of the visual apertures 111, 112 further provide visual access to a third and fourth opening 123ii, 124ii, respectively. Each of the third and fourth opening 123ii, 124ii is configured for receiving fastening means and each opening is arranged in one of the corresponding planes P1, P2.

[0059] The first bracket leg 11 has a longest length extension in the third dimension 3D between a first bracket side 15 and a second bracket side 16. The first bracket side 15 and second bracket side 16 extends in the first dimension 1D. The mounting bracket 10 has other bracket sides extending in the first dimension such as closer to the bend 13 but the distance between these two sides is not the longest length extension in the third dimension 3D.

[0060] The mounting bracket has a centre plane C extending in the first dimension 1D and the second dimension 2D parallel to the two planes P1, P2. The centre plane is arranged centrally between the first and second bracket sides 15, 16.

[0061] The mounting bracket 10 shown in Figs 2A and 2B is a wide bracket with the first bracket leg 11 having a length extension in the third dimension 3D which is larger than the length extension of the first leg in the first dimension 1D. Visual openings are especially relevant in this kind of brackets where the openings for fastening means 123i, 124i are also arranged closer to the centre plane C than to any one of the first and second bracket sides 15, 16. In this kind of mounting brackets, the openings are especially difficult to observe without the visual apertures 111, 112. In this kind of brackets the planes P1, P2 and therefore the visual openings 111, 112 are arranged closer to the centre plane (C) than to any one of the first and second bracket sides (15, 16) to align the visual apertures 111, 112 with the openings 123i, 124i.

[0062] Each aperture of the first bracket leg 11 has a length extension L in the first dimension 1D and a width extension W in the second dimension 2D. The length extension L of each aperture 111, 112 is larger than the corresponding width extension W of said aperture. This provides an aperture formed as an oblong aperture. The oblong shape provides good visual access to the openings 123i, 124i even if the visual angle of the observer changes slightly or if more than one opening is to be observed through each aperture.

[0063] Each aperture has an edge delimiting the circumference of said aperture, such as seen in Fig. 2B where the aperture edge 112e is visualized. The distance from each aperture 111, 112 to the bend 13 equals the length extension of said aperture in the third dimension 3D.

[0064] The length extension of each visual aperture 111, 112 in the first dimension 1D is larger than the length extension of the associated opening 123i, 124i in the second dimension 2D, and the length extension of each visual aperture 111, 112 in the third dimension 3D is larger than the length extension of the associated opening 123i, 124i in the third dimension.

[0065] When observing one of the openings, such as the opening 123i through the aperture 111 in Fig. 2B, the shape and size of the aperture 111 and the size ratio between the aperture 111 and opening 123i provides visual access to the immediate surroundings of the opening 123i. This makes it easier for the installer to target the opening 123i with a fastening means when mounting the bracket.

[0066] In the embodiment shown in Figs. 2A and 2B each aperture in the first bracket leg 11 has a length to width ratio of 5 to 2. Additionally, the oblong shape of the visual apertures 111, 112 allows an installer to observe two openings through each visual aperture as best seen in Fig. 2B where a third opening 123ii can be observed through the first aperture 111 and a fourth opening 124ii can be observed through the second aperture 112.

[0067] Turning to Figs. 3A to 3C, an alternative mounting bracket 10' is shown where the length extension of the first bracket leg 11 in the first dimension 1D equals the length extension of the first bracket leg 11 in the third dimension 3D. This mounting bracket further has a second set of apertures comprising a third aperture 121 and a fourth aperture 122 arranged in the second bracket leg 12. The bracket legs 11, 12 are mirror images of each other and are arranged at a 90 degrees angle in the bend 13. The first bracket leg 11 comprises openings 113i, 113ii, 114i, 114ii arranged to be visually accessible through the apertures 121, 122 in the second bracket leg.

[0068] In this embodiment the visual apertures 111, 112 each has a length extension L in the first dimension of 23 mm. The corresponding openings 123i, 124ii each has a length extension of 4 mm.

[0069] Fig. 3C shows the mounting bracket 10' from Figs. 3A and 3B from a normal viewing angle, wherein the visual opening 111 in the first plane P1 also provides direct visual access to the opening in the second plane P2. Similarly, the visual opening 112 in the second plane P2 provides direct visual access to the opening in the first plane P1.

[0070] Turning to Figs. 4A and 4B and alternative mounting bracket 10" is shown. The first bracket leg 11 of the mounting bracket 10" extends in the first leg plane FLP, which is defined by the first dimension 1D and third dimension 3D, and the second bracket leg 12 extends in the second dimension 2D. The second bracket leg 12 comprises a first bracket section 21 and a second bracket section 22.

[0071] The two bracket sections extend in different planes in that the first bracket section 21 extends in the first dimension 1D and third dimension 3D, and the second bracket section 22 extends in the second dimension 2D and third dimension 3D. Each of the visual apertures 111, 112 are oblong openings but has the length extension in the third dimension 3D and first dimension 1D, respectively. However, embodiments may be envisioned where the oblong openings extend in the same dimension for brackets, where mounting is performed in a particular viewing angle. In the mounting bracket 10" the opening 123i is arranged in the first bracket section 21, and the opening 124i is arranged in the second bracket section 22, and the planes P1 and P2 are perpendicular to each other, however embodiments may be envisioned where both openings 123i, 124i are arranged in the same bracket section. The first and second bracket sections 21, 22 extend individually from the first bracket leg 11.

[0072] The second bracket leg 12 further comprises a protrusion 50 configured for being inserted in a groove in the building component to which it is mounted.

[0073] In principle, the mounting bracket of the present invention may be used in connecting various types of building components. However, the mounting bracket is specifically advantageous for use in connecting a roof window to a roof structure.List of reference numerals

[0011] In some embodiments, the bend extends along the third dimension, and the second bracket leg extends in the third dimension and the second dimension. The planes in which apertures are arranged may extend in the first dimension and the second dimension.

[0012] The first plane may alternatively be perpendicular to the second plane.

[0013] The second bracket leg may comprise a first bracket section and a second bracket section. The first bracket section may extend in the first dimension and the second dimension. The second bracket section may extend in the second dimension and the third dimension.

[0014] The first aperture may be arranged in the first bracket section.

[0015] The second aperture may be arranged in the second bracket section.

[0016] Alternatively, the first and second apertures are both arranged in either the first or second bracket section.

[0017] The first section and a second section may be separated and may individually extend from the first leg.

[0018] The first section, second section and first bracket leg may meet in a corner edge.

[0019] The visual apertures may be especially advantageous in mounting brackets comprising a second bracket leg with bracket leg sections extending in different planes because this can obstruct the viewing angles even further.

This is especially true if the opening configured for receiving fastening means is arranged closer to the centre plane than to any one of the first and second bracket sides.

[0025] Each visual aperture of the first bracket leg may be formed as an oblong aperture. The oblong aperture has the advantage of providing better visual access to the opening for fastening means under normal installation condition i.e. installing the bracket with a normal viewing angle with the installer being in a normal working position. Additionally, it allows the installer to take slightly different positions with different viewing angles and still see the opening.

[0026] The length extension of each visual aperture in the first dimension may be larger than the length extension of the associated opening in the second bracket leg in the second dimension. This has the advantage that the installer can observe the entire length of the opening for fastening means through the visual opening.

[0027] Alternatively, the first aperture may be longest in the third dimension and the second aperture may be longest in the first dimension. This is especially advantageous in embodiments where the first and second planes are arranged perpendicular to each other.

[0028] Each aperture of the first bracket leg may have a width extension in the third dimension at least the width of the associated opening in the third dimension. Alternatively, the width extension of each visual aperture may be larger than the width extension of the associated opening in the third dimension. This has the advantage of providing better visual access to the opening for receiving fastening means as well as to the most proximal surroundings of that opening, making it easier to navigate a fastening means towards the opening and allowing the installer to take slightly different viewing angles and still see the entire opening.

[0029] The dimensions of at least one of the apertures of the first bracket leg may be selected such that the length extension in the first dimension of the aperture is larger than the width extension in the third dimension by a factor in the range of 2 to 10, preferably in the range of 3 to 6.

[0030] The dimensions of at least one of the apertures of the first bracket leg may be selected such that the length extension in the first dimension is larger than the length extension of the associated opening in the second dimension.

[0031] The opening may be a circular opening. Alternatively, the opening may be an oblong opening. The opening may have a length extension in the second dimension which exceeds the length extension in the third dimension.

[0032] The set of apertures may comprise a first aperture and a second aperture in the first bracket leg, preferably located substantially equidistantly from the centre plane as seen in the third dimension, wherein the associated planes are substantially parallel. Preferably, each aperture is arranged with a distance to the centre plane.

[0033] The visual apertures may be arranged equidistantly to the centre plane. Additionally, the visual apertures may be arranged with an offset to the centre plane.

[0034] An end edge of each aperture as seen in the first dimension may be located at a distance from the bend not exceeding the width extension of the aperture in the third dimension.

[0035] The set of openings in the second bracket leg comprises a first opening opposite the first aperture in the first bracket leg. The first opening and the first aperture are arranged in the same first plane.

[0036] The mounting bracket further comprises a second opening opposite the second aperture. The second aperture and the second opening are arranged in the same second plane.

[0037] The mounting bracket may comprise a third opening arranged above or below the first opening as seen in the second dimension.

[0038] The mounting bracket may comprise a fourth opening arrange above or below the second opening as seen in the second dimension.

[0039] The mounting bracket may comprise a second set of visual apertures in the second bracket leg.

[0040] Each aperture comprised in the second set of apertures may each be centred in one of the first and second planes.

[0041] The first bracket leg may comprise at least one opening for receiving fastening means. Each of the at least one openings in the first bracket leg may be aligned with an aperture comprised in the second bracket leg.

[0042] The first bracket leg and the second bracket leg may be mirror-images of each other i.e. the first bracket leg and second bracket leg may have equal length extensions in the first, second, and third dimensions. This has the advantage that the first bracket leg may function as the second bracket leg and vice versa providing a more versatile mounting bracket.

[0043] The first bracket leg may have a longest length extension in the third dimension between a first bracket side and a second bracket side, wherein the distance from the one opening to the bend is shorter than the distance from the opening to any one of the first and second bracket side.

[0044] In a second aspect this and further objects are achieved with a roof window comprising a set mounting brackets according to the first aspect.

[0045] In a third aspect this and further objects are achieved with a method of mounting a mounting bracket according to the first aspect, comprising the steps of arranging the second side of the second bracket leg on the first building component, attaching the mounting bracket to the first building component by inserting a fastener into the first opening from the first side of the second bracket leg while visually observing the first opening and the fastener through the first aperture.

[0046] The method may further comprise the step of inserting a fastener into the second opening from the first side of the second bracket leg while visually observing the second opening through the second aperture.

[0047] A feature described in relation to one of the aspects may also be incorporated in the other aspect, and the advantage of the feature is applicable to all aspects in which it is incorporated.

[0048] Other presently preferred embodiments and further advantages will be apparent from the subsequent detailed description and drawings.Brief Description of Drawings

Description of Embodiments

[0050] In the following detailed description, preferred embodiments of the present invention will be described. However, it is to be understood that features of the different embodiments are exchangeable between the embodiments and may be combined in different ways, unless anything else is specifically indicated. It may also be noted that, for the sake of clarity, the dimensions of certain components illustrated in the drawings may differ from the corresponding dimensions in real-life implementations.

[0051] It is noted that terms such as "up", "down", "left-hand", "right-hand", "exterior", "interior", "outer", "inner" are relative and refers to the viewpoint in question. In general, when referred to an exterior side, this relates to a side of a roof window in the mounted condition facing the outdoors or external side of the building.

[0052] Referring initially to Fig. 1, a roof window 1 is shown. In the initial general description, the shown roof window is representative of an embodiment of the invention and of the prior art as shown and described in Applicant's EP 4 187 037 A1, in the embodiment shown in Fig. 3 of the EP document. Only details of relevance are shown and will be described in detail. Elements having the same or analogous function as in the present invention are denoted by the same reference numerals as will be referred to in the description of embodiments of the invention.

[0053] In Fig. 1, a first building component 1 in form of a roof window 1 is installed in a second building component 100 in the form of a roof structure 100 of an inclined roof surface (not shown). The roof window comprises a frame 2. The frame 2 comprises a set of frame members including a top frame member (not shown), two side frame members 22 and a bottom frame member 24. Further elements of the roof window 1 may include a sash with a pane, connected to the frame 2 by means of a set of hinges 5. The roof structure 100 is represented by a number of rafters of which one rafter 101 is shown, on top of which battens 102, 103 are shown as well as an auxiliary batten 104. A first set of four prior art mounting brackets 6 is provided and connected to the frame 2, near the corners of juxtaposed frame side members and frame top / bottom member, here to the bottom frame member 24 resting on auxiliary batten 104. A second set of mounting brackets 7 is provided, here connected to the side frame member 22 near the position of the hinge 5. In case the roof window 1 is intended to be installed at a lower installation level than the one shown in Fig. 1, the mounting bracket 6 of the first set would instead be connected to the side frame member 22, at a higher level of the frame 2, and resting on the rafter 101 while the mounting bracket 7 of the second set would be turned such that its second leg points downwards.

[0054] Fig. 2A shows an embodiment of a mounting bracket 10 according to the invention.

[0055] The mounting bracket 10 has a first bracket leg 11 extending in a first dimension 1D and a second bracket leg 12 extending from the first bracket leg 11 in a second dimension 2D perpendicular to the first dimension 1D. The first bracket leg 11 adjoins the second bracket leg 12 in a bend 13 extending along a third dimension 3D perpendicular to the first dimension 1D and the second dimension 2D. The first bracket leg 11 therefore extends in a first leg plane FLP which is defined by the first dimension 1D and the third dimension 3D. In the shown embodiment, the second bracket leg 12 extends in the second dimension 2D and the third dimension 3D.

[0056] The second bracket leg 12 has two openings 123i, 124i each centred in one of two respective planes P1, P2. Each opening 123i, 124i provides a through-hole from a first side of the second bracket leg 1201 to a second side of the second bracket leg 1202 as seen in the first dimension 1D.

[0057] Each of the openings 123i and 124i are configured for receiving a fastening means, such as a screw, from the first side to the second side of the second bracket leg 12.

[0058] The first bracket leg 11 has a set of apertures 111, 112 each centred in one of the respective associated first plane P1 and second plane P2. Each aperture is configured for providing visual access to one of the openings 123i, 124i of the second bracket leg 12, as best seen in Fig. 2B, where the alignment of the apertures 111, 112 and openings 123i, 124i in the planes P1, P2 provide visual access to the openings from a position an installer typically takes when installing a mounting bracket. The perspective shown in Fig. 2B shows a normal viewing angle for an installer in a normal working position. The mounting bracket may have to be installed in a tight space without the possibility to observe the openings 123i, 124i by looking underneath or around the sides of the first bracket leg 11. Each of the visual apertures 111, 112 further provide visual access to a third and fourth opening 123ii, 124ii, respectively. Each of the third and fourth opening 123ii, 124ii is configured for receiving fastening means and each opening is arranged in one of the corresponding planes P1, P2.

[0059] The first bracket leg 11 has a longest length extension in the third dimension 3D between a first bracket side 15 and a second bracket side 16. The first bracket side 15 and second bracket side 16 extends in the first dimension 1D. The mounting bracket 10 has other bracket sides extending in the first dimension such as closer to the bend 13 but the distance between these two sides is not the longest length extension in the third dimension 3D.

[0060] The mounting bracket has a centre plane C extending in the first dimension 1D and the second dimension 2D parallel to the two planes P1, P2. The centre plane is arranged centrally between the first and second bracket sides 15, 16.

[0061] The mounting bracket 10 shown in Figs 2A and 2B is a wide bracket with the first bracket leg 11 having a length extension in the third dimension 3D which is larger than the length extension of the first leg in the first dimension 1D. Visual openings are especially relevant in this kind of brackets where the openings for fastening means 123i, 124i are also arranged closer to the centre plane C than to any one of the first and second bracket sides 15, 16. In this kind of mounting brackets, the openings are especially difficult to observe without the visual apertures 111, 112. In this kind of brackets the planes P1, P2 and therefore the visual openings 111, 112 are arranged closer to the centre plane (C) than to any one of the first and second bracket sides (15, 16) to align the visual apertures 111, 112 with the openings 123i, 124i.

[0062] Each aperture of the first bracket leg 11 has a length extension L in the first dimension 1D and a width extension W in the second dimension 2D. The length extension L of each aperture 111, 112 is larger than the corresponding width extension W of said aperture. This provides an aperture formed as an oblong aperture. The oblong shape provides good visual access to the openings 123i, 124i even if the visual angle of the observer changes slightly or if more than one opening is to be observed through each aperture.

[0063] Each aperture has an edge delimiting the circumference of said aperture, such as seen in Fig. 2B where the aperture edge 112e is visualized. The distance from each aperture 111, 112 to the bend 13 equals the length extension of said aperture in the third dimension 3D.

[0064] The length extension of each visual aperture 111, 112 in the first dimension 1D is larger than the length extension of the associated opening 123i, 124i in the second dimension 2D, and the length extension of each visual aperture 111, 112 in the third dimension 3D is larger than the length extension of the associated opening 123i, 124i in the third dimension.

[0065] When observing one of the openings, such as the opening 123i through the aperture 111 in Fig. 2B, the shape and size of the aperture 111 and the size ratio between the aperture 111 and opening 123i provides visual access to the immediate surroundings of the opening 123i. This makes it easier for the installer to target the opening 123i with a fastening means when mounting the bracket.

[0066] In the embodiment shown in Figs. 2A and 2B each aperture in the first bracket leg 11 has a length to width ratio of 5 to 2. Additionally, the oblong shape of the visual apertures 111, 112 allows an installer to observe two openings through each visual aperture as best seen in Fig. 2B where a third opening 123ii can be observed through the first aperture 111 and a fourth opening 124ii can be observed through the second aperture 112.

[0067] Turning to Figs. 3A to 3C, an alternative mounting bracket 10' is shown where the length extension of the first bracket leg 11 in the first dimension 1D equals the length extension of the first bracket leg 11 in the third dimension 3D. This mounting bracket further has a second set of apertures comprising a third aperture 121 and a fourth aperture 122 arranged in the second bracket leg 12. The bracket legs 11, 12 are mirror images of each other and are arranged at a 90 degrees angle in the bend 13. The first bracket leg 11 comprises openings 113i, 113ii, 114i, 114ii arranged to be visually accessible through the apertures 121, 122 in the second bracket leg.

[0068] In this embodiment the visual apertures 111, 112 each has a length extension L in the first dimension of 23 mm. The corresponding openings 123i, 124ii each has a length extension of 4 mm.

[0069] Fig. 3C shows the mounting bracket 10' from Figs. 3A and 3B from a normal viewing angle, wherein the visual opening 111 in the first plane P1 also provides direct visual access to the opening in the second plane P2. Similarly, the visual opening 112 in the second plane P2 provides direct visual access to the opening in the first plane P1.

[0070] Turning to Figs. 4A and 4B and alternative mounting bracket 10" is shown. The first bracket leg 11 of the mounting bracket 10" extends in the first leg plane FLP, which is defined by the first dimension 1D and third dimension 3D, and the second bracket leg 12 extends in the second dimension 2D. The second bracket leg 12 comprises a first bracket section 21 and a second bracket section 22.

[0071] The two bracket sections extend in different planes in that the first bracket section 21 extends in the first dimension 1D and third dimension 3D, and the second bracket section 22 extends in the second dimension 2D and third dimension 3D. Each of the visual apertures 111, 112 are oblong openings but has the length extension in the third dimension 3D and first dimension 1D, respectively. However, embodiments may be envisioned where the oblong openings extend in the same dimension for brackets, where mounting is performed in a particular viewing angle. In the mounting bracket 10" the opening 123i is arranged in the first bracket section 21, and the opening 124i is arranged in the second bracket section 22, and the planes P1 and P2 are perpendicular to each other, however embodiments may be envisioned where both openings 123i, 124i are arranged in the same bracket section. The first and second bracket sections 21, 22 extend individually from the first bracket leg 11.

[0072] The second bracket leg 12 further comprises a protrusion 50 configured for being inserted in a groove in the building component to which it is mounted.

[0073] In principle, the mounting bracket of the present invention may be used in connecting various types of building components. However, the mounting bracket is specifically advantageous for use in connecting a roof window to a roof structure.List of reference numerals
