[0001] 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 a plurality of mounting brackets, where the side members and
the top and bottom members of the frame in the mounted position of the window extend
essentially parallel to rafter and batten elements, respectively, in the roof structure,
and where each mounting bracket comprises a first leg portion for connection with
an associated frame member and a second leg portion which is essentially perpendicular
to the first leg portion and is to be fastened to the roof structure.
[0002] A window of this kind, e.g. known from the international publication no WO-A-88/04348,
is anchored in the roof structure in the way that a number, usually four or six, of
fixing angles sectionally L-shaped are by one leg fastened to the side members of
the frame, and the window is then mounted in the roof opening and fastened by the
second leg by screws to the subjacent roof structure, the rafters or the battens.
[0003] Prior to the mounting, however, the spacing between the battens and their positioning
must be measured in order to avoid that a mounting bracket is placed opposite a cut
batten end, when mounted on the subjacent roof structure, whether a rafter element
or alternatively a counter batten situated parallel to and on said rafter element.
[0004] This measuring is an obvious source of error and can be the reason for considerable
delays during mounting, as an erroneous measuring implies that the mounting bracket
has to be removed after the window has been mounted in the roof opening. In particular,
when mounting two or more windows next to each other, this measuring is critical since
the leg of the mounting bracket perpendicular to the frame side member must necessarily
have a certain length in order to assure a good abutment against the roof structure
and, depending on the distance between the windows, it may thus result in the mounting
brackets on two adjacent frame side members of neighbouring windows not being placed
opposite each other.
[0005] Therefore, it is the object of the invention to provide a window with associated
mounting brackets having as a result an optimal rationalization in connection with
the mounting of the window and, at the same time, the risk of erroneous measuring
and mounting is minimized.
[0006] According to the invention, this is obtained in the way that each mounting bracket
is designed as a gusset, said first leg portion being formed as two leg sections essentially
perpendicular to each other for connection with adjacent frame members at the joint
hereof.
[0007] By such a window, the desired simple mounting is obtained in the way that the window
can easily be positioned correctly without previous measuring and without particular
considerations to the spacing of the battens. The window is put up in the roof opening
with a mounting bracket provided at each frame corner joint and is placed on either
continuous battens above or under the frame top and bottom members, respectively,
or auxiliary batten pieces extending preferably parallel hereto and being positioned
parallel to the other battens. Subsequently, the window is fastened to the roof structure
by screwing mounting screws in the second leg portion of the mounting bracket through
the batten element and down in the subjacent rafter structure.
[0008] In an advantageous embodiment, the second leg portion of the mounting bracket is
designed as two plate-shaped leg sections placed in one plane, each being perpendicular
to and integrally connected with an associated leg section of the first leg portion.
In this way, a further improved abutment between the window and the roof structure
is obtained just as an actual reinforcement of the corner joints is achieved.
[0009] The two leg sections of the second leg portion are preferably designed essentially
symmetrically in relation to a bisecting plane for a corner joint of two adjacent
frame members and with sides extending parallel to the associated frame member. In
addition to obtaining a standardization, as the one and same bracket can be mounted
at all the corner joints of the window, this embodiment entails that the mounting
of more windows beside or above each other can take place in a simple and advantageous
manner.
[0010] In a further development of this embodiment, the leg sections are essentially shaped
as parallelograms, in which the mounting bracket seen from above is arrow-headed.
This further entails an advantage as to production technique and storage, because
several mounting brackets can be produced from a strip material blank and, having
been folded to form the two leg portions, can be piled one on top of the other.
[0011] In a preferred embodiment, the frame has, at least in an area at the corner joint
between two adjacent frame members, a groove extending in the longitudinal direction
of each frame member, and in the end opposite in relation to the second leg portion,
the mounting bracket is provided with a flange perpendicular to each leg section of
said first leg portion to be inserted in said groove. This embodiment provides a particularly
good and secure connection between the bracket and the frame and a further simplified
mounting, the assembler being instructed where to mount the mounting bracket in the
vertical direction of the frame members, and thus the positioning of the window in
relation to the surrounding roofing is determined.
[0012] In a particular embodiment, which is in particular advantageous when mounting windows
next to and/or above each other, engagement means are provided at each lateral edge
of the leg section of the second leg portion for connection with the mounting bracket
of a neighbouring window, whereby the mounting and aligning work of thus situated
windows is considerably facilitated.
[0013] These engagement means are preferably designed as at least one projection-recess
pair.
[0014] In order to provide a simple outside insulation of the frame in the mounted position
of the window, the mounting bracket is appropriately provided with at least one partially
punched flap which, in the mounted position, is folded in the direction towards the
roof structure. This flap marks the distance to a batten element above and below,
respectively, the top and bottom member of the frame such that e.g. a plate of insulating
material can be inserted between the frame and the roof structure.
[0015] In another aspect of the invention, a mounting bracket with the features stated in
claims 9-16 is obtained.
[0016] The invention will in the following be explained in more detail with reference to
the schematic drawings, in which
Fig. 1 shows a perspective view of a window according to the invention mounted in
a pitched roof,
Fig. 2 is a perspective view of an embodiment of a mounting bracket according to the
invention,
Fig. 3 is a plane view of a second embodiment of the mounting bracket according to
the invention,
Fig. 4 is, on a small scale, a plane view showing an integration of four windows according
to the invention by means of several of the mounting bracket shown in Fig. 3,
Fig. 5 is a plane view of yet another embodiment of the mounting bracket according
to the invention during a manufacturing step, and
Fig. 6 is, on a small scale, a plane view showing a material blank for manufacturing
of a series of mounting brackets as shown in Fig. 5.
[0017] In Fig. 1, a window 1 is shown in a mounted position in a pitched roof structure
comprising rafters 2 extending in the direction of the roof pitch and battens 3 placed
perpendicular hereto. For the sake of clearness, only the exterior frame of the window
1 is shown with two side members 4, 5 extending parallel to the rafters 2 and a top
member 6 and a bottom member 7 extending parallel to the battens. An auxiliary batten
8 is placed above the last continuous batten 3 below the bottom member 7, just as
an auxiliary batten 9 has been placed above the top member 6. In a not shown mounting
situation, at least the lower auxiliary batten is placed at an appropriate distance
from the nearest continuous roof batten in order to give way to positioning of the
roofing material in such a way that the flashing can subsequently be placed in a satisfactory
way, preferably without having to adapt it by an irregular deformation in order to
obtain a secure waterproof flashing.
[0018] The frame members 4-7 are connected with each other in corner joints, by which the
frame via mounting brackets 10 is anchored in the roof structure in that screws (not
shown) are led through the auxiliary battens 8, 9 and further down in the subjacent
rafters 2.
[0019] In Figs. 2-6 are shown different embodiments of such a bracket. Parts with identical
or analogue functions will all have same reference numbers when the various embodiments
are described.
[0020] As shown in Fig. 2, the mounting bracket 10 is designed as a symmetrical gusset with
a plane of symmetry corresponding to the bisecting plane of the corner joints. The
bracket 10 has a first leg portion 11 consisting of two rectangular leg sections 11a,
11b meant to be fastened to e.g. the frame bottom member 7 and the side member 5,
respectively. Two plate-shaped leg sections 12a, 12b extend perpendicular to the leg
sections 11a, 11b, and form together a second leg portion 12 which is meant, in a
mounted position, for abutment against the top side of a batten 3 or, as indicated
in Fig. 1, preferably against the lower or upper auxiliary batten 8 or 9. The leg
sections 12a, 12b are essentially shaped as parallelograms such that the mounting
bracket 10 seen from above is arrow-headed where the head points away from the corner
joints of the frame, as it appears from Fig. 1.
[0021] In the opposite direction, a flange 13a, 13b extends perpendicular to each leg section
of the first leg portion 11, only one flange 13a being shown in Fig. 2. The flanges
13a, 13b are meant for insertion in grooves in the frame members which can be provided
either with one circular groove, with more circular grooves in different heights on
the frame or with grooves which are only provided at the corner joints themselves.
[0022] The second leg portion 12 is, in the dividing line between the two leg sections 12a,
12b and at a distance from the connection with the first leg portion 11, provided
with a partially punched flap 14 which before mounting, preferably during the manufacture,
is folded downwards in the direction towards the first leg portion 11, i.e. in the
mounted position towards the roof structure. In the folded and mounted position, this
flap abuts against the side of the subjacent batten or auxiliary batten and entails
that the batten element always keeps a minimum distance to the top or bottom member
of the frame such that e.g. a plate of insulating material can be inserted in this
interspace. In other roof structures, as e.g. concrete roofs or other "plane" structures
where the bracket will be placed directly on the plane supporting portion, the flap
will be bendable backwards so that it is flush with the leg portion 11.
[0023] Finally, the mounting bracket 10 in the second leg portion 11 has a number of preferably
recessed holes 15 serving to receive screws which are screwed down in the batten element
and further down in the subjacent rafter structure after the mounting bracket 10 is
positioned around a frame corner and the flanges 13a, 13b are fitted into the associated
grooves in the frame members.
[0024] In the preferred mounting situation, the auxiliary battens are thus serving as mere
support or spacer pieces, and the auxiliary batten may be divided into two separate
parts. A structure is thus obtained where the load transmission is passed directly
from the mounting bracket and down in the subjacent rafter structure via the mounting
screws which provides the most secure load transmission where the quality of the roof
battens is secondary.
[0025] A further embodiment of the mounting bracket is shown in Figs. 3 and 4. Only differences
in relation the above-stated embodiment are described in details.
[0026] In the lateral edge of one leg section 12a of the second leg portion 12, a semicircular
cylindrical projection 16 is provided having a complementary shape in relation to
a recess 17 on the lateral edge of the second leg section 12b. For production-technical
reasons which will be explained further in the following, the flange 13a has a corresponding
recess 18 which has, however, no influence on the fastening of the mounting bracket
to the frame member.
[0027] Furthermore, the flange 13b can at its end facing away from the plane of symmetry
be provided with a flap 13c which has been folded downwards in an angle of preferably
45° around the dashed folding line 13d. Thus, by boring one hole at a frame groove,
it can be assured that the bracket 10 can be mounted in one way on the frame, i.e.
by having the flap 13c entering the hole.
[0028] As shown in Fig. 4, the projection 16 and the recess 17 serve as engagement means
for fixation of the brackets in relation to each other when integrating two windows
beside and, in this case, above each other. The mounting bracket 10 for the window
1 is thus in engagement with a corresponding mounting bracket 110 on a window situated
at the side and a mounting bracket 210 on a window 201 situated below. The mounting
brackets 110 and 210 are at each their side in engagement with a mounting bracket
310 on a fourth window 301. All four mounting brackets 10, 110, 210, 310 are on the
manner described above fastened to the batten 3 and rafter 2 of the roof structure
and the folded flaps 14, 114, 214, 314 abut against the side of the batten 3 whereas
the rafter 2 unobstructedly avoids the flaps.
[0029] Fig. 5 shows a step during manufacturing of a mounting bracket 10 according to the
invention. From a strip material blank shown in Fig. 6 and comprising four future
mounting brackets, the various details of the finished mounting bracket are punched,
i.e. the flap 14, the fastening holes 15, engagement means 16, 17 and further engagement
means 19, 20 together with a slot 21 forming the dividing line between the two leg
sections 11a and 11b in the first leg portion. After dividing the strip material blank
into four parts, each part is folded in relation to the second leg portion 12 along
the dot-and-dash lines 22a, 22b and the dashed folding lines 23a, 23b to form the
flanges 13a, 13b and the leg sections 11a, 11b of the first leg portion, respectively,
and finally the flap 14 is folded in the desired angle in relation to the plane through
the second leg portion 12.
[0030] Even though the mounting bracket has essentially the same shape in the embodiments
described above, modifications are certainly possible within the frame of the following

positioned in each their leg section 12a, 12b.
