Description

The present invention relates to a window for installation in a roof structure, comprising a frame with a top member, a bottom member and two side members mutually connected in corner joints and together forming an external limit along the outer sides of the frame, and a plurality of mounting brackets, where each mounting bracket comprises a first leg portion for connection with an associated frame member and a second leg portion essentially perpendicular to the first leg portion in the mounted position for fastening to the roof structure, and where the first leg portion comprises at least one leg section for connection with a frame member at a corner joint.
A window of this kind, known from EP 1042589 B1 , is installed in a roof structure In the way that, without prior measuring, a number, usually four, of mounting brackets are fastened to the frame of the window by the first leg portion and to the roof structure by the second leg portion.
Windows of this known type are usually delivered at the installation site with associated mounting brackets, which are not pre-mounted on the frame of the window. Therefore, an extra mounting step is required at the installation site, which takes extra time and implies a risk that the mounting brackets are mounted incorrectly on the frame and/or the roof structure or even that the brackets are lost during the process.
If windows of the known type are instead delivered with mounting brackets pre-mounted on the frame to ensure correct mounting, the second leg portion of the brackets will protrude from the frame of the window, making the window take up a disproportionate amount of space during transportation. This requires a similarly large packaging, which is highly disadvantageous in itself. Moreover, such packaging will have a space between the outer edge of the packaging and the frame of the window corresponding to the size of the protruding part of the brackets. This will imply a risk of damage, particularly to both the packaging and the brackets, but also to other parts of the window structure during transportation of the window.
Therefore, it is the object of the invention to provide a window of the type mentioned in the introduction, whereby correct and simple mounting is ensured, the risk of damage to the window as well as the packaging during transportation of the window is minimized and a reduction of the quantity of packaging material is obtained.
According to the invention, this is obtained by a window of the type described in the introduction, in which the first leg portion and the second leg portion are interconnected by means of a connecting member in such a way that the second leg portion is essentially within the external limit of the frame in a transport position of the window, while the second leg portion is essentially outside the external limit of the frame in a mounted position of the window.
Such a window allows the mounting bracket to be pre-mounted on the frame of the window, thereby essentially simplifying the mounting process, ensuring correct installation of the window and particularly the mounting bracket, and preventing loss of the brackets.
Moreover, in such a window all the parts of the mounting bracket are within the external limit of the frame during transportation of the window so that the risk of damage to the packaging and/or the mounting bracket during transportation of the window is minimal and so that the window can be packed in a packaging corresponding in size to the external limit of the frame, thereby optimising the quantity of packaging material used.
In a preferred embodiment of the window according to the invention, the first leg portion further comprises a lower and an upper edge, and the second leg portion further comprises a lower and an upper side, and the first leg portion and the second leg portion are further interconnected by means of a connecting member in such a way that the upper side of the second leg portion faces in the opposite direction of the upper edge of the first leg portion in a transport position of the window, while the upper side of the second leg portion faces in the same direction as the upper edge of the first leg portion in a mounted position of the window. In this way, a window is provided which can be brought from a transport position to a mounted position in a particularly simple and gentle manner, especially for the mounting bracket.
In a particularly preferred embodiment of the window according to the invention, the first leg portion comprises two leg sections, and the two leg sections of the first leg portion are interconnected by means of the said connecting member, and the sum of the angles between the connecting member and each of the two leg sections amounts to essentially 270 degrees, thereby in a particularly simple way achieving secure abutment of the two leg sections against respective frame members.
In a particularly preferred embodiment of the window according to the invention, the said connecting member interconnecting the first and the second leg portions is essentially perpendicular to the second leg portion, and each corner joint comprises a bevelling, the bevelling being designed for abutment with the connecting member, and the connecting member comprises at least one hole for passing through a fastening device for fastening the connecting member to the bevelling. This embodiment provides a window which allows the necessary steps for pre-assembling the window in the manufacturing phase to be made in a particularly simple way.
In a preferred embodiment of the window according to the invention, the connecting member comprises a first connecting section connected with the first leg portion and a second connecting section connected with the second leg portion, and a transition portion integrally interconnecting the first and the second connecting sections, the first and the second connecting sections being in continuation of each other in a transport position, and the first and the second connecting sections being made to overlap each other in a mounted position by swinging about a swinging axis defined by the transition portion. By such swinging, the mounting bracket can be brought from a transport position to a mounted position essentially without imparting any torque to the connecting member, thereby achieving optimum strength of the bracket in the mounted position.
In a preferred embodiment of the window according to the invention, the first connecting section and the second connecting section are of essentially the same dimensions, thereby obtaining a complete overlap of the two connecting sections in a mounted position and thus no unnecessarily protruding edges.
In a preferred embodiment of the window according to the invention, the connecting member comprises a locking member near the former's end facing away from the second leg portion in a transport position, the locking member being designed, in a mounted position, to engage with a corresponding locking member provided near the end of the connecting member adjacent to the second leg portion, thereby providing a window with optimum stability in a mounted position.
In a particularly preferred embodiment of the window according to the invention, the connecting member comprises a locking device, the locking device being connected integrally with the connecting member at the latter's end facing away from the second leg portion in a transport position, and the locking device comprising a locking member designed to engage with a corresponding locking member provided in the second leg portion in a mounted position. Thereby, the mounting bracket and the locking device can be manufactured in a particularly simple manner, e.g. by punching in one piece.
In a particularly preferred embodiment of the window according to the invention, the said locking device is essentially perpendicular to the connecting member and extends in a plane parallel with the second leg portion, whereby the two locking members are automatically made to at least abut each other when the bracket is swung from a transport position to a mounted position.
In a further preferred embodiment of the window according to the invention, each of the two leg sections of the first leg portion comprises holes for passing through fastening members and/or a flange which is essentially perpendicular to the leg section and is designed for engagement with a corresponding groove provided in the frame of the window, whereby the fastening of the first leg portion to the frame of the window can be made in a satisfactory manner.
In a further preferred embodiment of the window according to the invention, the second leg portion comprises holes for passing through fastening members and/or engagement members designed for engagement with a corresponding mounting bracket of an adjacent window and/or at least one flap folded in a direction towards the roof structure in a mounted position.
In a further preferred embodiment of the window according to the invention, a baseplate which is essentially perpendicular to the connecting member and extends in a plane parallel with the second leg portion is provided at the end of the connecting member, whereby the mounting bracket protects the corner joint on which it is installed from external influences.
In a second aspect of the invention, a mounting bracket has been provided with features according to any one of claims 13 to 24.
Further aspects of the invention comprise a method for installing a window according to the invention by use of mounting brackets according to the invention, and use of such mounting bracket for installing a window according to the invention.
The invention will be explained in more detail below by means of a non-limiting example of an embodiment and with reference to the schematic drawings, in which

Fig. 1 shows a perspective top view of an embodiment of a window according to the Invention in a transport position,
Fig. 2 shows a perspective top view of the window according to Fig. 1 in a mounted position,
Fig. 3 shows an embodiment of a mounting bracket according to the invention in a transport position,
Figs. 4A and B show an embodiment of a mounting bracket according to the invention in a mounted position, seen from two different angles, and
Fig. 5 shows another embodiment of a mounting bracket according to the invention in a transport position.

Fig. 1 shows an embodiment of a window according to the invention. The window 1 comprises a frame with a top member 2, a bottom member 3, and two side members 4 and 5 as well as a plurality of mounting brackets 10. Usually, the window 1 comprises four mounting brackets 10, only one being shown in Figs. 1 and 2. The top member 2 and the bottom member 3 are connected with the side members 4 and 5 in corner joints 6, and the frame thus assembled forms an external limit along its outer sides. Each corner joint 6 preferably comprises a bevelling 7, the function of which will be described below. Fig. 1 also shows that each mounting bracket 10 comprises a first leg portion 11 and a second leg portion 12 interconnected by a connecting member 13.
The window of Fig. 1 is shown in a transport position, and it is apparent that each mounting bracket 10 in the transport position is placed so that the second leg portion 12 essentially lies within the external limit formed by the outer sides of the window frame.
Fig. 2 shows the window 1 according to Fig. 1 in a mounted position, in which the window is mounted in a roof structure (not shown). It is apparent that the mounting bracket 10 is now placed so that the second leg portion 12 essentially projects beyond the external limit formed by the outer side of the window frame so that the second leg portion 12 can be fastened to the roof structure by means of a fastening device (not shown), such as a screw.
Fig. 3 shows a mounting bracket 10 according to the invention in a preferred embodiment in a transport position, and Figs. 4A and 4B show a top and bottom view, respectively, of a corresponding bracket in a mounted position. The mounting bracket 10 comprises a first leg portion 11, a second leg portion 12 and a connecting member 13.
The mounting bracket 10 according to the invention is of the gusset type, and the first leg portion 11 therefore comprises two leg sections 11a and 11b intended for fastening to a respective frame member 2, 3, 4 or 5 adjacent to the place where the frame members are interconnected in a corner joint 6. For fastening purposes, each leg section 11a, 11b has at least one mounting hole 27 for passing through a fastening device (not shown). Each leg section 11a, 11b of the first leg portion 11 comprises a lower edge 14 and an upper edge 15 and may further, in a manner known per se, in connection with the lower edge 14 in the embodiment shown, comprise flanges 30 intended for engagement with corresponding grooves (not shown) provided in the frame members.
The second leg portion 12 is essentially perpendicular to the first leg portion 11 and comprises a lower side 16 and an upper side 17. The second leg member comprises mounting holes 28 for passing through fastening devices (not shown) for the purpose of fastening the second leg portion 12 to the roof structure during the installation. Further, the second leg portion 12 may in a manner known per se comprise a folded flap 29. In a mounted position, this flap 29 abuts the roof structure and causes a minimum distance to be maintained between the roof structure and the top or bottom member of the frame so that insulating material may be inserted in this space. Likewise, in a manner known per se, the second leg portion 12 may comprise, at its outer edge, an engagement member, e.g. in the form of a projection 32 and a recess 33 intended for engagement with a corresponding engagement member on a mounting bracket of an adjacent window as in the embodiment shown.
The connecting member 13 comprises two ends 13a and 13b, the end 13a being connected to the first leg portion 11 and the end 13b being connected to the second leg portion 12. Preferably, as in the embodiment shown, the connecting member 13 and the leg portions 11 and 12, respectively, are integrally interconnected, whereby the entire mounting bracket 10 can be punched from a plate in one punching operation. Preferably, as appears from Figs. 3 and 4, the connecting section 13 and the second leg portion 12 are perpendicular to each other, while the connecting member 13 and the leg sections 11a, 11b of the first leg portion 11 are preferably at an angle of 135 degrees to each other. It will be sufficient, however, if the sum of the angles between the connecting member and the leg sections merely amounts to approximately 270 degrees. If the angle between the connecting member 13 and one or both of the leg sections 11a, 11b is thus slightly larger than 135 degrees in an embodiment, and if this is combined with the above embodiment in which the flanges 30 on the leg sections 11a, 11b are designed with a number of projections, it thus becomes possible for the projections and the complementary recesses in the grooves to function as temporary retention of the bracket until, by means of e.g. blows with a claw hammer, the installer can bring the leg sections into such an angle with the connecting member that permanent retention is provided.
The connecting member further comprises a hole 18 for passing through a fastening device (not shown), so that the mounting bracket 10 can thereby be fastened to the frame of a window, preferably to a bevelling 7 as shown on the window 1 in Figs. 1 and 2. For this purpose, the bevelling 7 is preferably provided with the same width as or a larger width than the connecting member 13 so that the connecting member 13 can abut against the bevelling 7 without protruding past the edge thereof. The hole 18 is preferably provided near the end 13a of the connecting member 13. The bevelling 7 is shown in Figs. 1 and 2 in an embodiment in which it is limited to the lower part of the height of the frame. In another embodiment, the bevelling is provided in the entire height of the frame.
In the embodiment shown, the connecting member 13 comprises two connecting sections 19 and 20 integrally interconnected with the first leg portion 11 and the second leg portion 12, respectively. The two connecting sections 19 and 20 are mutually and continuously interconnected by means of a transition portion 21. In the embodiment shown, the transition portion 21 is designed so that it comprises a central portion 21a connected to the middle of the connecting section 20 and is connected at its opposite ends 21b and 21c to the connecting section 19.
In other embodiments, the connecting member may comprise two separate connecting sections interconnected by a mechanical hinge which allows movement of the bracket from a transport position to a mounted position. Alternatively, one of the two separate connecting sections may be designed so that it can be dismounted from the remaining part of the bracket in a transport position together with the swingable leg portion of the bracket, whereupon the dismounted part of the bracket is rotated and again fastened to the remaining part of the bracket in a mounted position. In that case, the dismounting and the subsequent fastening may, e.g., be effected by means of a locking mechanism such as a snap lock, or in that one separate connecting section is designed with groove-shaped recesses extending in parallel with the plane in which the connecting section extends, and the second separate connecting member is designed with complementary projections for engagement with the recesses, which further makes it possible to adjust the bracket in height relative to the frame.
In a transport position as shown in Fig. 3, the connecting sections 19 and 20 and the transition portion 21 between them are in continuation of each other and in the same plane. In this way, the transition portion 21 in the embodiment shown defines a swinging axis around which the second leg portion 12 and the adjacent connecting section 20 are swung until the connecting sections 19 and 20 abut against each other in a mounted position as shown in Fig. 4. It thus appears from Fig. 3 that the connection described between the first leg portion 11 and the second leg portion 12 causes the second leg portion 12, in a transport position, to lie essentially within a volume area delimited outwards by a plane containing the first leg portion 11. Similarly, it appears from Fig. 4 that the swinging described above implies that the second leg portion 12 is essentially outside the volume area in a mounted position. At the same time, the said swinging implies that the upper side 17 of the second leg member 12, from facing towards the upper edge 15 of the first leg portion 11 in a transport position, faces away from the upper edge 15 of the first leg portion 11 in a mounted position, thus enabling correct mounting In and fastening to the roof structure.
The mounting bracket 10 further comprises a locking member 22 and a corresponding locking member 23. The locking member 22 is designed to engage with the corresponding locking member 23 for firm locking and further stabilisation of the mounting bracket when it is brought into a mounted position. In a preferred embodiment as illustrated in Fig. 4A, the locking member and the corresponding locking member are designed as a hole and a rivet, respectively, connected with the mounting bracket by means of a flat spring.
In the embodiment shown, the locking member 22 is provided in a locking device 24 arranged perpendicularly to the connecting member 13 and integrally with it at the end 13a in the area between the leg sections 11a, 11b, and the corresponding locking member 23 is provided in the second leg portion 12 in an area near the end 13b of the connecting member 13. The locking device 24 is preferably designed with a shape so that, when the first leg portion 11 has been fastened to the window frame, the locking device will essentially fall within such area as is cleared when a bevelling 7 is provided. In the embodiment shown, the locking device 24 is brought to abut against the second leg portion 12 by swinging of the second leg portion 12 into a mounted position so that the locking member 22 can be brought into engagement with the corresponding locking member 23, whereby the mounting bracket is firmly locked in the mounted position as shown in Fig. 4.
In another embodiment of the window according to the invention, the mounting bracket may be provided with a baseplate 35 at the end 13a of the connecting member 13 as illustrated in Fig. 5, the baseplate 35 being essentially perpendicular to the connecting member 13 and parallel with the second leg portion 12, thereby protecting the corner joint of the frame against external influences. In an embodiment in which the mounting bracket comprises such baseplate, it will further be possible to design the bracket with only one leg section or completely without leg sections 11a and 11b, respectively. In an embodiment in which the bracket is designed without leg sections and at the same time designed so that it is adjustable in height, it will further be possible to omit the baseplate 35.
In a supplementary alternative embodiment, the transition between the locking device 24 and the end 13a of the connecting member 13 may be made resilient to improve the abutment between the locking device 24 and the second leg portion 12. Such resilient design may further be supplemented by or alternatively be provided in the actual end 13a of the connecting member. This resilient design may e.g. be provided by the use of material softer than the material used for the remainder of the locking device 24 and the end 13a.
It should be noted that the above description of preferred embodiments serves only as an example, and that a worker skilled in the art will know that numerous variations are possible without deviating from the scope of the claims.
