Description
FIELD OF THE INVENTION
[0001] The invention relates to a wing for a window or a door with
a profile frame, which forms a rabbet receiving an insulating glass
component and has a perimeter surface that surrounds the insulating
glass component on the end side thereof and a rabbet surface that
extends beyond the edge of the insulating glass component, and with
an adhesive layer for securing the insulating glass component
within the rabbet, said adhesive layer filling, at least in
perimeter areas, a perimeter slot between the end surfaces of the
insulating glass component and the perimeter surface of the rabbet
located opposite said end surfaces.
DESCRIPTION OF THE PRIOR ART
[0002] To simplify the installation of an insulating glass
component, it is known (EP 1 070 824 A2) to bond the insulating
glass component into a rabbet of the profile frame. For this
purpose, a stripe of adhesive is applied along the rabbet surface
of the perimeter frame rabbet, which is parallel to the insulating
glass component, prior to inserting the insulating glass component
into the rabbet. During insertion, the insulating glass component
is therefore pressed against the perimeter stripe of adhesive which
performs the function of joining together the insulating glass
component and the profile frame. The disadvantage of this known
construction however is that the load resulting from the insulating
glass component is only to be carried away onto the profile frame
through the ridge of the rabbet that extends beyond the insulating
glass component. Moreover, the inner pane only is supported by the
frame, the outer pane however not, said outer pane being carried by
the inner pane through the edge connection between inner pane and
outer pane, which involves the risk that the outer panes will sag
on one side because of the perimeter slot provided between the end
surfaces of the insulating glass component and the perimeter
surfaces of the rabbet which are oriented parallel to said end
surfaces.
[0003] To permit easy fixation of a laminated glass in a profile
frame of an explosion proof window, it is known (EP 1 004 740 A2)
to bond the laminated glass inserted into a frame rabbet using a
layer of adhesive that fills the perimeter slot between the
laminated glass and the rabbet. In order for the adhesive layer to
be confined to the end surface areas of the laminated glass, a
profile bar that defines the adhesive layer can be bonded in the
transition area between the perimeter surface of the rabbet and the
adjacent rabbet surface overlapping the edge of the laminated
glass. Even if the adhesive layer is cut through, this profile bar
impairs the replacement of the laminated glass because there
remains, above the profile bar, a bonding bridge to the profile
frame. Moreover, the profile bar makes it more difficult to remove
the humidity entering between the laminated glass and the frame
profile, leaving the adhesive layer exposed to the adverse effect
of humidity.
[0004] Although it is known (DE 41 42 151 A1), for the purpose of
exchanging an insulating glass component that has been secured by
bonding, to provide for an auxiliary frame that is removably
secured to the wing of the window and carries the insulating glass
component, this very auxiliary frame complicates the construction.
Furthermore, the auxiliary frame, which is secured to the
insulating glass component through an adhesive layer, cannot be
removed from the insulating glass component.
SUMMARY OF THE INVENTION
[0005] It is therefore the object of the invention to improve,
using simple means, a wing of a window or a door of the type
mentioned herein above that retains the advantages of the known
bonding connection between the insulating glass component and the
profile frame, more specifically in regard to assembly, without
presenting the disadvantages, above all with respect to the
exchangeability of the insulating glass component.
[0006] The objective of the invention is accomplished by providing,
at a distance from the front of the rabbet surface, in the region
of a cover pane of the insulating glass component that faces the
rabbet surface, a perimeter boundary ridge for confining the
adhesive layer.
[0007] The boundary ridge not only permits to locally confine the
adhesive layer to the end surface area of the insulating glass
component, but also to provide advantageous conditions for
replacing the insulating glass component because the adhesive layer
may be cut through as far as the boundary ridge without risk of
damage to the profile frame, since the boundary ridge is disposed a
distance from the front of the rabbet surface overlapping the edge
of the insulating glass component and may thus be damaged without
impairing the frame. The boundary ridge may be assigned to the
insulating glass component or to the profile frame. In both cases,
the boundary ridge is allowed to unrestrictedly perform its
functions.
[0008] With the boundary ridge ending at a distance from the front
of the insulating glass component or of the perimeter surface of
the rabbet, the existing allowance not only makes it more easy to
insert the insulating glass component into the frame rabbet but
also facilitates replacement of the insulating glass component when
the need arises because the adhesive layer can be cut through
throughout its extent without residual bonding bridges in the
region of the allowance provided between the securing ridge and the
insulating glass component or the perimeter surface of the rabbet.
The size of the possible allowance depends on the flow behavior of
the not yet cured adhesive as it is being introduced into the
perimeter slot provided between the insulating glass component and
the perimeter surface of the rabbet, though. Another possibility to
completely separate the adhesive layer consists in severing the
boundary ridge together with the adhesive layer, which requires the
boundary ridge to be designed accordingly.
[0009] The free spacing between the boundary ridge and the rabbet
surface overlapping the edge of the insulating glass component
constitutes an advantageous drain for humidity at worst entering
this region. To assist in removing humidity alongside the frame
legs, the perimeter surface of the rabbet may form a recessed
groove on the side of the boundary ridge that faces the rabbet
surface.
[0010] To manufacture a wing in accordance with the invention, the
insulating glass component is at first inserted into the rabbet of
the profile frame and then the perimeter slot provided between the
end surfaces of the insulating glass component and the perimeter
rabbet surface located opposite said end surfaces is filled up to
the boundary ridge, at least in perimeter areas, with an elastic
adhesive. After the adhesive layer that fills the perimeter slot
has been cured, the wing may be fully loaded. If the adhesive is
injected into the perimeter slot around the entire perimeter, a
sealed connection is established between the profile frame and the
insulating glass component around the perimeter without additional
provisions being required. The adhesive may hereby be injected or
forced under pressure, into the perimeter slot. If the adhesive
were applied prior to inserting the insulating glass component,
there would be a risk of shearing it off during jointing, with the
resulting connection not providing a material positive
connection.
[0011] The adhesive layer in the perimeter slot provided between
the insulating glass component and the rabbet of the profile frame
that surrounds the insulating glass component is intended to
provide good support for the individual panes of the insulating
glass component relative to the profile frame. This may be
advantageously ensured if the perimeter slot is filled with
adhesive to a depth corresponding to the thickness of the
insulating glass component so that the width of the thus obtained
stripe of adhesive corresponds to the overall thickness of the
insulating glass component. The adhesive must be sufficiently
elastic so as to be capable of undergoing tensile stresses
generated by different thermal expansion coefficients between the
bonded materials without impairing the bonding connection.
[0012] A hot melt adhesive is preferably utilized. Such a hot
melt-type adhesive may be processed when hot and is capable of
fixing the insulating glass component in the profile frame as a
result of the increase in viscosity during the cooling stage so
that the wing may undergo further processing shortly after the
adhesive has been applied. If, in addition, said adhesive is
capable of thermoplastic deformation, it is ensured that, when the
wing is caused to move, the bonding connection remains intact and
the adhesive will not peel off the frame profile as this could be
the case with crystalline thermoplastic adhesives. It has been
found out that, with the adhesive bond hardening within about 30
seconds to two hours after the hot melt adhesive has cooled down,
the needs of window and door construction can be well met. The use
of a reactive adhesive constitutes another possibility. It has been
found that two-component adhesives, more specifically
polyurethane-based, epoxide-based or (meth)acrylate-based ones, are
particularly suited. Such type reactive adhesives allow for fast
hardening in conjunction with strong manipulability.
[0013] To be suited, the adhesive has to exhibit a certain
stability and an appropriate viscosity. It is hereby to be taken
into account that the adhesive is to be applied to a sufficient
coating thickness on the one side and that the force needed to
process the adhesive under pressure is not too large on the other
side.
BRIEF DESCRIPTION OF THE DRAWING
[0014] The subject matter of the invention is shown by way of
example in the drawing wherein
[0015] FIG. 1 is a detail view of a wing for a window or a door in
accordance with the invention showing the cross-section of a frame
leg,
[0016] FIG. 2 is a view of a design variant corresponding to the
illustration shown FIG. 1 and
[0017] FIGS. 3 through 5 are schematic top views of a line for
manufacturing wings in accordance with the invention in various
work positions.
DESCRIPTION OF THE PREFERRED EMBODIMENT
[0018] A wing of a window or a door in accordance with the
invention consists of a profile frame 1 and of an insulating glass
component 2 that is inserted in a perimeter rabbet 3 of the profile
frame 1. To this purpose, the rabbets 3 of the frame legs 4 form a
perimeter surface 6 that is located opposite the end surfaces 5 of
the insulating glass component 2 and that encloses the insulating
glass component 2. An adhesive layer 7, which fills the perimeter
slot 8 provided between the end surfaces 5 of the insulating glass
component 2 and the perimeter surface 6 of the rabbet 3, serves to
secure the insulating glass component 2 in the rabbet 3. As the
adhesive layer 7 has a width that is adapted to the thickness of
the insulating glass component 2, the cover panes 11 of the
insulating glass component 2, which are joined together through a
spacer profile 9 and a seal 10, are supported individually relative
to the frame legs 4, which permits to advantageously divert the
load from the insulating glass component 2 onto the frame legs 4.
The bonding achieved in this way has the advantage that the
stiffness of the insulating glass component 2 may be used without
restriction to confer stability to the wing.
[0019] From the FIGS. 1 and 2 it can be seen that the rabbet 3 of
the profiles of the frame legs 4 forms a rabbet surface 12 that
overlaps the edge of the insulating glass component 2; however, as
opposed to conventional wings, this rabbet surface 12 does not
serve to secure the insulating glass component 2, but is only
intended to cover the perimeter edge of the insulating glass
component 2, with a seal 13 that fits said edge in the region of
the rabbet surface 12 being provided. On the opposite inner side of
the insulating glass component 2, the edge thereof is covered by a
covering profile 14 and a seal 15 retained in the covering profile
14, said seal in turn only accomplishing sealing functions and
playing no part in retaining the insulating glass component 2.
Therefore, the covering profile 14 only needs to be snapped into a
groove 16 of the frame leg 4.
[0020] To manufacture a wing in accordance with the invention, the
profile frame 1, which is formed by the assembled frame legs 4, is
positioned onto an assembly table 17 so that the insulating glass
component 2 may be inserted into the rabbet 3 intended to receive
it using a hoisting device 18. Said hoisting device 18 is comprised
of a lifting device 20 provided with suction cups 19 in order to
align the received insulating glass component 2 relative to the
profile frame 1 on the assembly table 17 and to insert it into the
profile frame 1 using a swivel arm 21. The perimeter slot 8 (FIG.
4) that remains between the inserted insulating glass component 2
and the rabbet 3 of the profile frame 1 may now be filled with an
adhesive, said adhesive being injected or forced under pressure
into the perimeter slot 8. To prevent the adhesive introduced into
the perimeter slot 8 from flowing out of the perimeter slot 8
toward the ridge 12 of the frame legs, said slot is closed by a
boundary ridge 22 provided in the region of the outer cover pane
11, said boundary ridge freely extending, according to FIG. 1,
beyond the perimeter surface 6 of rabbet 3 at a distance from the
rabbet surface 12. As a result, the perimeter slot 8 is only filled
with adhesive to a depth that corresponds to the thickness of the
insulating glass component 2 in order to make sure the desired
bonding connection between the end surfaces 5 of the insulating
glass component 2 and the frame legs 4 is achieved. After the
adhesive introduced into the perimeter slot 8 has been cured by
cooling or reactivity, the assembled wing may be lifted through the
insulating glass component 2 from the assembly table 18 using the
hoisting device 18 and may be moved to possible further processing
stations. The manipulability of the wing is not dependent on the
chemical curing of the adhesive, which may occur later.
[0021] The boundary ridge needs not be assigned to the frame legs
4. As can be seen from FIG. 2, a boundary ridge 22 that is mounted
to the cover pane 11 neighboring the rabbet surface 12 also meets
the requirements placed thereon with regard to the local
confinement of the adhesive layer 7 to the area of the end surfaces
5 of the insulating glass component 2, this providing the advantage
that the adhesive layer 7 may be severed later on, either in the
region of the slot remaining between the boundary ridge 22 and the
insulating glass component (FIG. 1) or the perimeter surface 6
(FIG. 2) resp., or in the region of the boundary ridge 22, which,
in this case, must also be cut through.
[0022] According to FIG. 1, the perimeter surface 6 between the
boundary ridge 22 and the rabbet surface 12 may form a recessed
groove 23 through which humidity possibly entering between the seal
13 and the insulating glass component 2 may be advantageously
drained so that the adhesive layer 7 needs not be disadvantageously
affected by humidity.
