[0001] The present invention relates to a method and a device for mounting a glass pane
in a window frame, especially to a frame made of wood or a frame of a material which
may be fixed by means of nails or staples.
[0002] In a prior art method and a prior art device for mounting a glass pane in a window
frame the glass pane which for example can consist of two panes connected with each
other for forming a sealed glazing unit is with its edge portion positioned in a fillister
in the window pane. The fillister is formed by a side surface and a bottom surface
and the glass pane is positioned in the fillister by positioning and sealing one side
surface of the edge portion of the glass pane against the side surface of the fillister
and by fixing a fastening strip by means of fastening elements to the bottom surface
of the fillister. Thereby, a side surface of the fastening strip faces the other side
surface of the edge portion of the glass pane and this side surface of the fastening
strip is sealed in relation to said side surface of the edge portion of the glass
pane. The fasting strip as well as the window frame consist of wood and the fastening
strip is fixed to the bottom surface of the fillister of the frame by means of nails
or staples which from the upper surface of the fastening strips are forced through
the fastening strip into the window frame. Thus, the prior art method and the prior
art device for mounting a glass pane in a window frame requires subsequent treatment
by for example filling or flatting for hiding the parts of the nails or the staples
positioned at the surface of the fastening strip or at least for making these portions
less visible.
[0003] A method for mounting a glass pane in a window frame made of wood according to the
introductory part of claim 1 is known from EU 0 015 842, however, the nails used for
fixing the fastening strip are hit in a manner so that the heads of the nails are
visible. Moreover, the hitting procedure is made while the fastening strip has to
be pressed against the pane in order to compress the sealing, which does not lead
to a reliable sealing.
[0004] The object of the invention is to provide a method and a device for mounting a glass
pane in a window frame obviating the disadvantages mentioned above.
[0005] In order to comply with this object the method for mounting a glass pane in a window
frame is in accordance with the invention characterized in that the fastening strip
is fastened to the bottom surface of the fillister by positioning the fastening means
in a groove formed in the fastening strip at the other side surface of the edge portion
of the glass pane and open towards the other side surface of the edge portion of the
glass pane and that the other side surface of the edge portion of the glass pane is
sealed in relation to the window frame by means of a sealing strip, consisting of
elastic material, the sealing strip being forced into the groove under compression
between the other side surface of the edge portion of the glass pane and an opposite
side surface of the groove while covering the portions of the fastening means positioned
at the surface of the groove.
[0006] Thus, when using the method for mounting a glass pane in a window frame in accordance
with the invention there is provided a fixing of the fastening strip to frame by means
of completely hidden nails or staples. The costly and time consuming subsequent treatment
is thereby completely avoided.
[0007] In a preferred embodiment of the method according to the invention the fastening
strip is prior to the fixing to the bottom surface of the fillister given a correct
position by positioning a reference surface of the fastening strip in a predetermined
position in relation to a reference surface of the window frame, the position of the
fastening strip being defined so that the sealing strip is subjected to the desired
compression when it is forced down into the groove. It is thereby suitable that said
reference surfaces are constituted by the side surface of the fastening strip turned
from the glass pane and the adjacent side surface of the window frame. Preferably
said side surface are positioned in the same plane.
[0008] In the method according to the invention the side surface of the edge portion of
the glass pane, which is positioned against the side surface of the fillister can
be sealed in relation to this side surface by means of an elastic material sealing
strip or by means of a silicone bead or the like.If the sealing of said edge portion
of the glass pane in relation to the side surface of the fillister is provided by
means of an elastic material sealing strip a fastening position of the fastening strip
at the bottom surface of the fillister is adapted so that said sealing strip as well
as the sealing strip forced into the groove in the fastening strip are subjected to
the desired compression.
[0009] The method according to the invention can be used when the glass pane consists of
a single pane as well as when the glass pane consists of an insulating glass pane
consisting of two or more panes sealingly connected with each other.
[0010] The device for mounting a glass pane in a window frame according to the invention
comprises a fillister formed in the frame comprising a side surface against which
one side surface of the edge portion of the glass pane is adapted to be positioned
and sealed, a fastening strip which is adapted to be fixed to the bottom surface of
the fillister by means of fastening means with one side surface facing the other side
surface of the edge portion of the glass pane and a sealing strip for sealing the
other side surface of the edge portion of the glass pane in relation to the fastening
strip, the fastening strip being formed with a groove positioned adjacent the other
side surface of the edge portion of the glass pane and open towards said side surface,
the fastening means being positioned in the groove for fixing the fastening strip
to the bottom surface of the fillister, and the device comprising an elastic material
sealing strip which under compression is positioned in the groove between the other
side surface of the edge portion of the glass pane and an opposite side surface of
the groove, the sealing strip covering the portions of the fastening means positioned
at the surfaces of the groove.
[0011] It is preferred that the sealing strip positioned in the groove the fastening strip
is at its side surfaces engaging the edge portion of the glass pane and the opposite
side surface of the groove formed with sealing lips for securing an efficient sealing
function and facilitating the forcing of the sealing strip into the groove.
[0012] In order to secure the drainage of water the sealing strip positioned in the groove
is formed whith an outer inclined surface forming with the edge portion of the glass
pane and angle exceeding 90°.
[0013] The invention shall be described in the following with reference to the accompanying
drawings.
[0014] Fig. 1 is a plan view of a window frame with a glass pane mounted therein in accordance
with the invention.
[0015] Fig. 2a is a section on line II-II of Fig. 1 through the bottom element of the window
frame shown in Fig. 1.
[0016] Figs. 2b and 2c are sections through sealing strips included in the window frame
as shown in Fig. 1 and 2a.
[0017] Fig. 3 is a section corresponding to Fig. 2a of a modified embodiment of a window
frame with a glass pane mounted therein in accordance with the method of the invention.
[0018] Fig. 4 is a section similar to Fig. 2a, however, directed to an embodiment in which
the fastening has no groove.
[0019] In Fig. 1 there is shown a plan view of a window frame 2 consisting of wood and comprising
side elements 4, an upper element 6 and a bottom element 8. An insulating glass pane
10 is by means of a peripherally extending fastening strip 12 mounted in the window
frame 2 by means of the device according to the invention. The fastening strip 12
consists of wood, foamed plastic material or any other material through which nails
or staples can be driven.
[0020] The sectional design of the side elements 4, upper element 6 and bottom element 8
of the window frame 2 appears from Fig. 2a but it is realized that this sectional
shape can be of any other design within the scope of the invention.
[0021] The window frame is formed with a fillister 14 which is of angular cross section
by being formed with a side surface 16 and a bottom surface 18. The side surface 16
and the bottom surface 18 form a substantially right angle with each other. Grooves
20 are in a conventional way formed at the bottom surface 18.
[0022] The insulating glass pane 10 is at its edge surface 22 supported in a conventional
way by means of setting blocks 24 in the fillister 14 of the frame. The edge portion
of the insulating glass pane 10 has a side surface 26 which is positioned and sealed
against the side surface 16 of the fillister, the sealing being provided by means
of a sealing strip 28 compressed between the side surface 16 of the fillister 14 and
the side surface 26 of the edge portion of the insulating glass pane 10. The cross
sectional shape of the sealing strip 28 is in a non-compressed condition shown in
Fig. 2b. Thus, the sealing strip 28 is constituted by a cellular rubber profile, consisting
for example of EPDM with substantially rectangular cross section having a hollow space
30 and bead shaped projections 32 at the surface adapted to engage the side surface
26 of the edge portion of the insulating glass pane.
[0023] The insulating glass pane 10 is locked into the fillister 14 by means of the fastening
strip 12. The fastening strip 12 has a side surface 36 facing the side surface 34
of the edge portion of the insulating glass pane and has in addition thereto a groove
38 open towards the edge portion 34 of the insulating glass pane. The groove 38 has
a bottom surface 40 and a side surface 42 facing the side surface 34 of the insulating
glass pane.
[0024] The fastening strip 12 is fixed to the bottom surface 18 of the window frame fillister
14 by means of nails 44 which from the bottom surface 40 of the groove 38 extend through
the fastening strip 12 into the wood material of the frame. The fastening strip 12
is fixed to the frame in such a position that the outer side surface 46 of the fastening
strip is positioned in the same plane as the adjacent side surface 48 of the window
frame. A sealing strip 50 is forced into the groove 38 in the fastening strip 12 and
is thus compressed between the side surface 34 of the edge portion of the insulating
glass pane and the opposite side surface 42 of the groove 38 in the fastening strip
12. The sectional shape of the sealing strip 50 in a non-compressed condition appears
from Fig. 2c. The sealing strip 50 is provided with sealing lips 52 and 54, thus engaging
the side surface 34 of the edge portion of the insulating glass pane and the side
surface 42 of the groove 38. The sealing strip 50 has an upper bevelled surface 56
forming an angle with the side surface 34 of the edge portion of the insulating glass
pane exceeding 90° and thereby providing a satisfying drainage of water from the window
pane. The sealing strip 50 completely hides the portions of the nails 44 visible at
the bottom 40 of the groove 38, and in accordance with the invention there is provided
a completely hidden fixing of the fastening strip 12 to the window frame without any
requirement for subsequent treatment of the window frame.
[0025] The dimensioning of the fastening strip 12 in relation to the fillister 14 and in
relation to the insulating glass pane and the sealing strips 28 and 50 is such that
the sealing strips 28 and 50 have the compression necessary for providing the desired
sealing function when the side surface 46 of the fastening strip 12 is positioned
in the same plane as the side surface 48 of the window frame.
[0026] The embodiment of the invention shown in Fig. 3 differs from the embodiment shown
in Fig. 2 in the respect that the side surface 26a of the edge portion of the insulating
glass pane 10a is sealed towards the side surface 16a of the fillister 14a by means
of a bead 60 of silicone positioned in a groove 58 in the window frame instead of
by means of the sealing strip 28. For the rest the embodiment according to Fig. 3
is in all essentials formed in agreement with the embodiment according to Fig. 2a.
[0027] The mounting of the insulating glass pane 10 in the window frame 2 is conducted substantially
in the following way: Initially the sealing strip 28 is applied to the side surface
16 of the fillister 14. It is preferred that the sealing strip 28 is at its surface
intended to be connected with the side surface 16 of the fillister 14 provided with
an adhesive covered by a removable tape. Thus, after the tape has been removed the
sealing strip 28 can in a simple way be fastened to the side surface 16 of the fillister
14. Thereupon, the insulating glass pane 10 is positioned in the fillister, the frame
2 thereby taking a horizontal position which means that the sealing strip 28 which
thereby will take up the weight of the insulating glass pane is subjected to a certain
precompression. The position of the insulating glass pane 10 in the fillister is thereupon
adjusted by means of the setting blocks 24. The fastening strip 12 is nailed in the
fillister 14 against the bottom surface 18 of the fillister, the side surface 46 of
the fastening strip 12 being positioned in the same plane as the side surface 48 of
the frame. Thus, the surfaces 46 and 48 constitute reference surfaces for defining
the correct position of the fastening strip 12 in the frame 2. The fastening strip
12 is fastened in the frame by means of nails or staples which are positioned in the
fixing strip 12 starting from the bottom 40 of the groove 38.
[0028] After the fastening strip 12 has been fixed to the frame the sealing strip 50 is
positioned in the groove 38 by being forced into the groove to the position as shown
in Fig. 2a. Thereby, the dimensions of the included elements, i.e. the fastening strip
12, the sealing strips 28 and 50 and the insulating glass pane, as well as the groove
38 in the fastening strip 12 and the position of the fastening strip 12 are related
so to each other that the sealing strips 28 and 50 are automatically provided with
the correct compression when the sealing strip 50 is forced into the groove 38.
[0029] In the embodiment according to Fig. 3 the side surface 26a and 34a of the edge portion
of the insulating glass pane directly contact the side surface 16a of the fillister
and the side surface 36a of the fastening strip 12a, respectively, which means that
the positioning of the including elements can be conducted in such a way that the
sealing strip 50a is subjected to the desired compression when it is forced into the
groove 38a.
[0030] The silicone bead 60 is supplied to the groove 58 subsequently to the finalizing
of the mounting of the insulating glass pane in the fillister.
[0031] The invention can be modified within the scope of the following claims. For example,
the sealing strip 28 can be formed with an upper bevelled surface for improving the
drainage of water from the glass pane in the case that the window frame is turned
so that the sealing strip 28 is positioned at the outside of the frame.
[0032] Also for the rest the invention can be modified within the scope of the following
claims.
[0033] Fig. 4 is showing another embodiment of the present invention, in which the fastening
strip 12 has no groove. Accordingly the nail 44 is hammered into the fastening strip
12 at the edge adjacent the pane 10.
