GLAZED WINDOW ASSEMBLY

GLAZED WINDOW ASSEMBLY
This invention relates to a glazed window assembly and
to a bead retaining clip for use in such assembly.
With the advent of fully finished timber windows there
has been a need for an installation method that would
securely fasten the side and top timber beads to the
exterior perimeter of a window without the use of
fixings which pierce the prefinished timber coating,
since such piercing affects the guarantee that the
paint manufacturers give for unpierced surfaces to the
joinery manufactures.
Accordingly, the present invention provides a glazed
window assembly comprising a window frame, a glazing
panel mounted in the window frame, a plurality of bead-
retaining clips located along at least one edge of the
panel, and a glazing bead extending in common along and
retained in position by the clips, each clip including
at least one tongue which extends rearwardly between
the frame and the edge of the panel for retaining the
clip in position relative to the panel, the tongue
having a plurality of teeth which are displaced out of
the plane of the tongue and which bite into the frame
to resist withdrawal of the tongue from between the
frame and the edge of the panel, and at least one bead-
retaining member which extends forwardly into a recess
in the rear surface of the glazing bead, the bead-
retaining member being offset upwardly relative to the
tongue.
The invention further provides a clip for use in a
glazed window assembly of the kind comprising a frame,
at least one glazing panel mounted in the frame, at
least one glazing bead mounted on the frame adjacent
one face of the panel, and a plurality of clips
positioned along the frame to retain the glazing bead
on the frame, the clip including at least one tongue
for extending between the frame and the edge of the
panel for retaining the clip in position relative to
the panel, the tongue having a plurality of teeth which
are displaced out of the plane of the tongue and which
bite into the frame to resist withdrawal of the tongue
from between the frame and the edge of the panel, and
at least one bead retaining member offset from and
extending in the opposite direction to the tongue for
extending into a recess in the rear of the glazing
bead.
In this specification, in respect of any given clip,
and irrespective of the actual orientation of the clip
in use, the forward direction is deemed to be the
direction normal to the glazing panel from the panel to
the glazing bead, the upward direction is deemed to be
the direction away from the edge of the frame towards
the centre of the panel, and the rearward and downward
directions are deemed to be the directions opposite to
the forward and upward direction respectively.
An embodiment of the invention will now be described,
by way of example, with reference to the accompanying
drawings, in which:
Figure 1 is a transverse cross—section of a glazed
window assembly taken through one vertical side edge of
a rectangular window frame;
Fig. 2 is a perspective View of the clip seen in cross-
section in Fig. 1; and
Fig. 3 is a top plan view of the clip of Fig. 2, the
cross—section of the clip in Fig. 1 being taken on the
line I—I of Fig. 3.
For convenience the glazed window assembly, and in
particular the clip, will be described with reference
to forward,
upward, rearward and downward directions,
indicated in Fig. 1 by the arrows F, U, R and D
respectively.
However, these directions do not limit
the orientation of the clip in use.
Referring now to the drawings, a glazed window assembly
comprises a rectangular window frame 10 with a glazing
panel 12 mounted in the frame. In this embodiment the
panel 12 is a sealed double glazing unit with inner and
outer glass panes 14, 16 respectively. A plurality of
bead retaining clips 18 are located along the edge of
the glazing panel 12. Preferably each clip 18 is
formed as an integral moulding of a rigid plastics
material such as PVC.
Typically the clips are 70mm
wide, as measured in the direction along the length of
the edge of the panel 12
Fig. 1),
(i e. normal to the plane of
and are spaced at intervals of 250mm. A pre-
finished wooden glazing bead 32 extends fully along the
exterior edge of the panel 12 adjacent the frame 10 and
is there held in place, in the manner now to be
described, in common by the clips 18.
Each clip 18 is generally step-shaped in cross-section
and comprises a central strip 20 which in use is
orientated substantially parallel to the edge of the
panel 12 and has upper and lower substantially parallel
edges 22, 24 respectively. A first tongue 26 extends
substantially at right angles to the strip 20 from the
lower edge 24 thereof rearwardly between the frame 10
and the edge of the panel 12 for retaining the clip in
position relative to the panel. A second tongue 28,
offset upwardly relative to the first tongue 26,
extends substantially at right angles to the strip 20
forwardly from the upper edge 22 thereof to engage in a
continuous narrow slot 30 in the rear surface of the
glazing bead 32.
To assemble the structure shown in Fig. 1, first each
clip 18 is fixed relative to the panel 12 by driving
the tongue 26 between the edge of the panel 12 and the
frame 10 in the manner of a wedge, the leading edge 34
of the upper surface of the tongue 26 being sloped to
facilitate this. The rear surface of the strip 20
facing the panel 12 has a plurality of ribs 36, and the
tongue 26 is driven between the edge of the panel 12
and the frame 10 until the ribs 36 come into abutment
with the panel 12, the ribs 36 thereby providing a
desired spacing between the strip 20 and the panel 12.
The glazing panel 12 is spaced from the rear of the
frame 10 by a self adhesive or press fit glazing gasket
36. To resist withdrawal of the tongue 26, the latter
is formed with a plurality, in this case two, of
reversely directed teeth 38 which are displaced out of
the plane of the lower surface 40 of the tongue to bite
into the wooden frame 10.
In this embodiment the tongue 26 can be up to 3mm
thick. This provides up to a 3mm space between the
edge of the panel 12 and the window frame 10, as
recommended by the United Kingdom Glass and Glazing
Federation. The opposite lateral edges 42 of the upper
surface of the tongue 26 are also sloped; this allows
to be inserted over these
tapered packers (not shown)
sloping edges between the tongue 26 and the edge of the
panel 12 should the latter be undersized.
Once the clips 18 are fixed in position along the edge
of the panel 12, the glazing bead 32 is pushed in
common onto the clips such that their tongues 28 enter
the slot 30. The bead 32 is pushed fully home until a
further glazing gasket 44 on the rear of the bead 32
comes to press against the panel 12. To retain the
bead 32 on the clips 18, each tongue 28 has a
plurality, in this case five, of reversely directed
teeth 46 which are alternately displaced out of the
plane of the upper and lower surfaces 48, 50 of the
tongue 28 to bite into the opposite sides of the slot
. Like the tongue 26, the leading edge of the tongue
28 is sloped to facilitate insertion of the tongue 28
into the slot 30.
Optionally, the clip 18 further has a pair of tabs 52
extending forwardly from the lower edge 24 of the strip
, each positioned laterally beyond a respective end
of the tongue 28, the tabs extending into a rebate 54
in the bottom surface of the bead 32.
It will be understood that the bead 32 is a single
elongate member extending substantially the full length
of the relevant edge of the unit 12, and is retained in
position in common by all the clips 18 fixed along that
edge which engage the bead at spaced locations. It
will be seen that the clips 18 do not engage any
exterior or exposed surface of the bead 32, and solely
hold the bead in place by engagement with the hidden
rear surface.
In the embodiment shown the clips 18 are designed for
use with a 20mm wide double glazing panel 12 and a bead
32 with a front to rear width of about 18mm. However,
the clips 18 may be manufactured with other dimensions
to suit other widths of unit 12 and bead 28.
As stated above, the drawing shows a cross—section
through one vertical side edge of the window frame, but
the same construction may also be used along the other
vertical side edge and along the horizontal top edge.
The construction is preferably not used along the
bottom edge of the window frame as a timber bead is
normally unsuitable — in that case it is preferred to
use, for example, an aluminium section.
The invention is not limited to the embodiments
described herein which may be modified or varied
without departing from the scope of the invention.
