[0001] The invention relates to a construction for a window or a door including a frame
and a sash provided with a glass element and hinged to the frame.
[0002] Openable windows with two sashs are mainly used in the Nordic countries. One such
window is the so-called MSE window, which opens inward, has two sashs and hinges at
the side. In the MSE window, the inner sash is equipped with a double pane thermal
glass and the outer sash with a flat glass.
[0003] In the other countries, a so-called DK (drehkipp) window is generally used, which
is a tilt and turn window with one sash. In this window type, a double or triple insulating
glass element is fitted to one sash. In addition, the sash is generally hinged with
special fittings, which allows opening the sash to the side as well as to the ventilation
position by means of the bottom hinges.
[0004] Attempts have been made to improve the heat insulation capacity of windows using
thermal pane glass and its various coatings. Nevertheless, heat bridges exist in known
windows. In addition, it is difficult to keep them clean and almost all of them look
the same. Due to massive constructions, only a part of the window opening can be utilised.
In other words, the viewing angle is limited. At the same time, thick sashs limit
the angle of opening, and the installation space between the sashs is reduced, which
may prevent installation of window blinds, for example. Furthermore, keeping the window
or the door clean is challenging.
[0005] The object of the invention is to provide a novel construction for a window or a
door, which includes fewer components than before and is easier to clean than heretofore.
The characteristic features of the construction according to this invention become
apparent from the appended claims. According to the invention, a novel glass element
and, if necessary, a sashless glass element, are surprisingly utilised in the construction
for a window or a door. Thus, the appearance changes and cleaning becomes easier and,
at the same time, the overall design is simplified and the installation space is increased.
Simultaneously, cleanability improves and influencing the appearance is enabled. In
addition, the number of the components decreases and the viewing angle increases.
However, a construction for a window or a door is simultaneously achieved that is
tighter than before. The U-value of the window or the door is lower than before. The
sashless concept increases luminosity and widens the viewing angle, and a novel appearance
is achieved via printing.

[0007] Figure 1 shows a construction for a window according to the invention in the opened
state. Generally, a construction for a window includes a frame 10 and a sash 11 hinged
to the frame 10. In addition, a glass element 12 is arranged in the sash 11 (shown
in more detail in Figures 3a and 3b). The construction for a window also includes
a sashless glass element 13, hinged to the frame 10, which is separate from the glass
element 12 of the sash 11. Without the sash, the thickness of the glass element is
only a fraction of that known. In addition, glazing beads as well as protrusions created
by the sash, which make cleaning more difficult, are avoided. In a known window construction,
the outer glass element has aluminium sashs, which conduct heat efficiently. This
disadvantageous construction and such a behaviour can now be avoided with the sashless
construction. At the same time, the viewing angle from inside to outside essentially
increases as the outer window element extends nearly to the frame. At the same time,
a large installation space remains in the window construction for window blinds, for
example.
[0008] In the embodiment shown, the sashless glass element 13 is composed of a single glass
pane 14, which requires a small space and is easy to fasten. Advantageously, the single
glass pane is tempered glass, whereby sufficient resistance is achieved. For example,
a thickness of six millimetres is sufficient for most window constructions.
[0009] It is now possible to have an influence on the appearance of a sashless glass element.
According to Figure 2, a sashless glass element 13 includes a digital printing pattern
15. Here, white colour has been used and the printing pattern encircles the entire
glass element as a narrow band, which is illustrated by a broken line. The form, size
and colour of the printing can be very freely selected. The printing is very durable
and cannot be scraped off. The printing is on one of the surfaces of the glass element;
however, it can also be made on both surfaces of the glass element, and the two surfaces
can be different. Thus, the appearance of the window can be influenced in a more versatile
way than before.
[0010] Furthermore, the sashless glass element 13 includes a hinge 16, which is fastened
to an opening 17 arranged in the sashless glass element 13. The hinge 16 is fastened
to the frame 10 in the normal way. Here the opening is a hole, made in the glass element,
to which the hinge is fastened with suitable fasteners and equipped with paddings.
In this way, breaking of tempered glass can be avoided. In the same way, two hold-open
devices 18, fastened to the sash 11, are fastened to the sashless glass element 13.
Thus, the whole window construction opens simultaneously. Certainly, separate locks
can be fitted to the sashless glass element for locking. This sash 11 has one locking
latch 19, which is operated with a handle 20.
[0011] The frame 10 is made of wood and includes metal fittings 22 equipped with a seal
21. In addition, the sashless glass element 13 is arranged to seal against said seal
21. Thus, a tight construction is achieved in a simple way and a heat bridge is not
generated between the metal fittings and the glass element, because the seal is present
all over between these. A double seal located more internally has seals in both the
frame and the sash. Thus, the sash contacts the frame seal in one point and the sash
seal encounters the frame in another point (not shown).
[0012] The construction for a window according to the invention also includes other surprising
characteristics. Namely, the outer surface 39 of the glass element 12 is essentially
flush with the face 23 of the sash 11. Thus, the window construction looks neatly
finished and is easy to keep clean, being free of the conventional steps. One method
of doing this is to arrange into the sash a rebate, essentially identical in depth
with the glass element, in which the glass element is placed (Figure 3b). The result
is tight and neatly finished.
[0013] External glazing beads are also missing from the window construction since a glued
joint is present between the sash 11 and the glass element 12. This facilitates the
manufacture and makes the whole unit composed of the sash and the glass element extremely
resistant and rigid. Thus, it is possible to manufacture quite large window constructions
using material strengths that are lower than before. As the space required by the
glued joint is taken into account in the dimensioning of the rebate, the glass element
is flush with the face of the sash in the final construction.
[0014] The sash 11 is also made of wood, which, being a massive construction, is a good
heat insulation. In addition, a glued joint forms a thermal barrier, which further
improves the tightness and insulation capacity of the window construction. Here, the
glass element 12 is also provided with a digital printing pattern 25 at least at the
glued joint 24. In the embodiments proposed, the printing is coloured and entirely
covers the glued joint. At the same time, the printing prevents access of UV beams
to the glued joint, which is thus protected by the printing. Again, the form, size
and colour of the printing can be very freely selected. Due to the massive sash, the
rebate can be made deep so that the glass element 12 can be formed of insulating glass.
In this insulating glass pane, an intermediate construction has been used to combine
two flat glass panes into one element, within which insulating gas can be supplied.
The insulating glass pane can also include several flat glass panes. The glued joint
may shine dark through the printing; however, it can be made invisible using suitable
print coverage.
[0015] Figures 4a and 4b illustrate another embodiment, in which the glass element 12 forms
the face 23 of the sash 11. In other words, the glass element extends to the entire
area of the sash. Thus, the glass element forms the most external part of the window
construction, in which case it is extremely easy to keep clean. In addition, the glass
surface covers almost the whole window, providing a completely novel appearance for
the window. Here, the glass element 12 is composed of three flat glass panes. The
glass element has a suitable hole or at least an opening for the handle. On the other
hand, a locking construction, operated at the side of the sash, can be fitted inside
the sash. Thus, the glass element can be fully continuous and an impressive printing
pattern can be added to it. The above-mentioned sash equipped with a glass element
can also be used for forming a DK window. Figures 5a and 5b illustrate a DK window
having a narrow frame 10 and a metal fitting 22 fastened thereto, which encircles
the entire frame forming the outer frame of the DK window. The sash 11 has almost
equal thickness with the frame and is provided with a rebate for the glass element
12. Seals and hinges are not shown; however, in the version proposed, triple sealing
can be used between the frame and the sash. A glued joint 24 is disposed between the
glass element 12 and the sash 11 according to the invention. Furthermore, the glass
element 12 is provided with a digital printing pattern 25. Here, too, the glass element
12 extends to the entire area of the sash 11 thus forming the face of the window construction.
The glass element proposed is triple.
[0016] Figure 6a is a partial cross-sectional view of a fourth embodiment of the window
according to the invention. As in Figure 3b, a sashless glass element 13 is supported
to a frame 10 by a hinge 16. Again, metal fittings 22, equipped with a seal 21, are
driven in the frame 10 (Figure 6b). In addition, a lock housing 27 equipped with a
latch bolt 26 is fastened to the sashless glass element 13, the latch bolt 26 being
arranged to abut against the metal fittings 22 when in the locked position. Thus,
the most external glass element 13 can be tightly locked. When in the closed position,
the glass element 13 abuts against the seal 21 and, correspondingly, the latch bolt
26 against the metal fittings 22. Here, the frame 28 of the lock housing 27 is glued
to the glass element 13. Such fastening is easy and strong and requires little space.
The glue is applied on both sides of the glass element, thus ensuring robust fastening.
The gaps between the frame 28 and the glass element 13 shown in Figure 6b are meant
for the glue. The lock housing 27 has a keyway 29, which allows releasing the window
lock with a conventional window-opening device. A sufficient number of lock housings
are glued to the glass element mainly depending on the size of the window.
[0017] Figure 7a is a partial cross-sectional view of a fifth embodiment of the window according
to the invention. Here, the sashless glass element 13 is almost equal with the embodiment
of Figure 6a. Instead, an opening 31, through which the locking device 32 disposed
in the sash 11 is fitted, is provided through the part 30 of the glass element 12
forming the face 23 of the sash 11 (Figure 7b). Here, too, the locking device 32 includes
a latch bolt 26, which locks to the counterpart 33 formed in the frame 10. The bar
34 of the locking device 32 uses the latch bolt 26 and the bar 34 extends through
the part 30 of the glass element 12. A handle or a turn knob is attached to the bar
(not shown). Due to the opening, a large glass surface can be used, the locking device
remaining hidden inside the sash. The bar can be left out, in which case the locking
device is operated with the above-mentioned window-opening device.
[0018] The construction described above is additionally provided with a low inner sash 11.
The novel construction is enabled by a glass element 12 glued from the interior. Thus,
the frame of the locking device 32 can be located further inwards than the outer edge
of the glass element 12. This being the case, a low sash can be used, thus achieving
a wider viewing angle than before. Despite the low construction, a robust locking
device can be used. In addition, connecting the glass element 12 and the sash 11 by
gluing provides a strong construction. Digital printing can be used in this embodiment
as well.
[0019] Figures 8a to 8d illustrate the construction for an internal door according to the
invention seen from different directions. Here the glass pane 35 is glued to a framing
timber 36. Expressed by the terms of the invention, the glass element forms the face
of the sash. The construction is simple and the entire face of the internal door is
glass, providing an unconventional appearance (Figure 8a). The appearance can be further
influenced by the printing 25, which is here rounded and covers the outer edges 37
of the entire glass pane 35.
[0020] Figures 9a to 9d illustrate the construction for an external door according to the
invention seen from different directions. Here the glass pane 12 of the external door
is glued to a framing timber 36 from inside. In the external door application, the
glass element also forms the face of the sash, which is directed towards the inside
of the building. Thus, seen from the inside, the entire face of the external door
is glass, providing an unconventional appearance (Figure 9d). In other words, the
face is towards the interior of the frame in this embodiment. The appearance can be
further influenced by the printing 25, which is here rounded and covers the outer
edges 37 of the entire glass element 12. Correspondingly, the framing timber 36 is
provided with a profiled chamfer 38, which allows water to flow away naturally. At
the same time, separate glazing beads are not necessary, and due to the glued joint,
the framing timber and the glass element form a rigid unit. Seals are not shown in
Figures 8e and 9e.

in the window or door construction when the face 23 is away from the frame 10. Correspondingly,
in the embodiment of Figure 9e, the sash 11 is the outer sash of those included in
