STRUCTURE AND OUTLINE SYSTEM FOR HERMETICAL AND ACOUSTIC
SEALING IN SLIDING WINDOWS AND DOORS.
The present invention relates to the closing of gaps,
which involves a system of door and window frames, sliding
windows and doors, in order to provide sealing around the
entire perimeter of the foil against any kind of noise and
fluid entry, with efficient acoustic without the foil being
ejected out of its own limits.
Prior Art
It is possible to affirm that the sealing and
insulating factor is one of the decisive elements when it
comes to a project of window and door frames designed for
any kind of use in commercial and residential buildings, as
well as boats, trains, etc. Currently, depending on the
region, on the installation of window and door frames, an
efficient acoustic insulation becomes essential.
According to the techniques currently known, door and
window frames with great acoustic insulation mean that they
function as a "cap" to the tightness of some external
agents (such as water, air, ventilation), as door and
window frames of the type maxim-air, ejecting, sliding /
pivoting or with a spinning system, opening or pivoting
with stop on the four sides of its perimeter. The use of
sliding door and window frames to run is not advisable due
to the low noise attenuation by the perimeter of the foil,
even if we use sealing tapes or other sealing element for
this end, such as gasket, rubbers, etc. Even the brushes,
which are typically used in projects of door and window
frames, they do not prevent the passage of sound, air and
water. So much so that the existing technical standards
currently allow the passage of air through the window and

door frame up to a determined limit, otherwise it would be
impossible to manufacture this product.
To improve the sealing in sliding door and window
frames, there is a method in which, after its closure, a
lever is enabled in order to move the whole body of the
foil downward, until the lower width of the foil rests or
touch the lower limit or the floor. Thus, the lower part of
the foil will have an efficient insulation, but the rest of
the perimeter of the foil will not have the same
performance, making that the door and window frame, as a
whole, not having a good acoustic insulation.
Still, another system, known in the state of the art,
using sliding door and window frames, and that despite
having an efficient acoustic insulation, incurs a very high
cost, in addition to fill up too much space. Basically, the
system consists of a door and window frames with two foils.
One of the foils is necessarily fixed and the other moves
in order to open or close the gap. When you want to open a
foil, we trigger a lever and a mechanism with a car of
movement and projection arms makes the foil leave its
plan, thus, moving transversally toward the inside of
environment in which the window or door is installed,
remaining parallel the fixed foil, but in a more internal
plane. When you want to close the foil, it is necessary to
push it, moving it back to its original plan and then,
through the command of the closing set it beside the
stationary foil, in order to play an effective acoustic
insulation. However, to achieve this goal it is also
necessary to a prominent outline in relation to the floor,
in order to provide a lower sealing of the foil. This
outline inevitably impedes the passage through that door.

Thus, it is necessary to overlap said outline. Moreover,
the aesthetic appearance is not pleasant, nor the operation
of movement for opening or closing of the foil, once,
moving it from the original closed plan to the projected
position parallelly to the flat foil implies in opening the
closure, pulling transversally the foil to the internal
side and then sliding this foil parallelly in order to open
the gap.
The system described above, as stated before, is
difficult to use because it occupies a considerable portion
of the internal area where it will be installed and also
because it is not possible to move the second foil. In
addition, said mechanism is robust, complex and expensive.
Given the above, there is no current technique that
uses sliding windows or doors, which offers an effective
sealing as to water, air and anti-acoustic properties, as
the effects provided with the use of windows or doors that
act as a "cap", as the case of the type maxim-air,
projecting /sliding or of the type of to open with a
pivoting or spinning system. Moreover, within the above
techniques, the embodiment that provides better sound
insulation has a high cost, and takes a considerable space
at the place where it will be installed.
Objective of the Invention
This invention has as an object a trigger mechanism
system for moving the foils of door and window frames, in
particular sliding door and window frames, so that the
sliding foil (door or window) is not extend out of the
dimensions of its limits. Still, the movement provided by
this system is not restricted to one foil only (door or
window), once the mechanism does not occupy extra space in

order to allow its opening in the installation place, and
does not requires a lower projecting outline to the floor
to get a seal, as what happens in the techniques presented
above. Finally, provides the continued sealing around the
perimeter of the foil.
Another objective of this invention is to provide
effective sealing throughout the perimeter of the foil for
windows and doors of the sliding type against any kind of
noise and fluid entry, with the same efficiency that is
obtained for windows of the type "cap". However, without
the complexity and difficulty that this system provides.
Brief Description of the Invention
The object of this invention is a structure and
outline system, specifically for sliding windows and doors
so that after the trigger of command system, by means of a
driven device, at first moment, the outline foil is shifted
through a set of transverse displacement of said system, so
that the foil can be moved transversely in relation to the
rail. Thus, the foil will be free to be moved, because it
will be no longer in contact with the seals. At a second
time that the trigger element is made to work for closing
the foil, the sealing is carried out efficiently throughout
the perimeter of this foil, through a device responsible
for transverse displacement of said command system.
Still, this invention objects sliding elements that
provide longitudinal and transverse movement of the foils
along the rail, and also elements of attachment, sealing
and moving due to the coupling between the foil and stops
or limits.

According to a preferential embodiment of the
invention, as can be seen from figure 1, 2, 3, 4, 5 and 6,
an outline structure system for sealing against the entry
of any type of fluid and noise in door and window frames,
of sliding windows and doors, associated to a displacement
device (15) with a set of transverse displacement comprised
of pulleys (2), which are arranged in the rail (3) of
frame. Still, the positioning of the sealing element(5),
which is pressed by a command element of transverse
displacement of the foil (1) named rotational control
device of the "fork with lever" type (10) and locks for
fixing (4) , as seen in Figures 3, 4, 5 and 6, can be done
in two different ways, and here defined, ensure efficiency
in the sealing between the foil (1), the rail (3) and limit
(7), over the entire perimeter.
As illustrated in figures 1, 2, 3, 4, 5 and 6, the
force performed by the trigger device (6), of the "cremona"
type, transfers the movement to the bars of command (11),
so that the displacement device (15) - with a set of
transverse displacement, which includes sliding elements of
the plane rolling type (13), preferably rollers - allow
such foil to move transversally. Thus, the foils are free
to perform a sliding movement smoother than the movement of
a single prior art sliding window since the foils are no
longer in contact with the limit (7) or with the rail (3).
This movement becomes useful, because the foil slides
transversally over said set of transverse displacement with
plane rolling (13), which is part of the displacement
device (15), which is arranged between said foil and rail
(3), without said foil (1) is projected out of the limit
(7) . Thus, no extra space is needed at the'interior where
CA 02680754 2009-09-14
WO 2008/113148 PCT/BR2008/000079

the system is installed, differently from one of the
systems described in the state of the art.
Simultaneously, the transverse displacement of the
foil (1), according to the figure 4, it is performed the
procedure for sealing said foil (1) against the entire
perimeter of the limit (7). Said sealing is performed by
the rotational control device of the "fork lever" type
(10), which is conjugated to the set of transversal
displacement through the foil (1). As said device (10) is
attached to the rail (3), by their rods, having a rotation
axis (12), and said device (10) being driven by the element
(6), preferably of the "cremona" type, and the command bars
(11), which, in turn, press movement on the transition
element (16), with said command bar (11), which is coupled
to the top of said device (10), which includes a diagonal
slot in one of its internal faces, which is responsible for
the transfer of linear motion, provided by the command bar
(11) for the device (10), turning into rotating moving
around its own axis (12), which, in turn, in rotation
motion, presses the sealing element(5), sealing the outline
foil (1), against the limit (7). Said rotational device
(10) is provided in at least two positions of the foil
outline (1).
Figure 4 illustrates an embodiment, in detail, of the
rotational control device (10), preferably a "fork command"
conjugated to the set of transverse displacement through
the foil (1), said device (1) attachable to the
transmission element (16), positioned on the opposite side
of the rail (3). The trigger device (6), of the "cremona"
type, permits that said rotational control device (10)
makes a rotation movement around its axis (12), thus moving
CA 02680754 2009-09-14
WO 2008/113148 PCT/BR2008/000079

the foil (1) on the rail (3), until it hit the sealing
element(5). Once the trigger element (6) is triggered for
closing, said outline foil (1) is forced against the
sealing element (5).
Figure 2 illustrates a second mode of the set of
command of this invention, that after the trigger of said
device (6), provides for the use of bars, with locking
devices (8) and (9), in the shape of a wedge, which force
said foil (1) against the sealing element (5), generating
thereby a proper seal in the system. The transfer of the
vertical movement of said lock in the shape of a wedge (8)
and (9) promotes the transverse displacement of the foil in
order to obtain an airtight and acoustic seal throughout
the periphery of the foil. When the element to trigger (6)
is opened, the foil is no longer fixed to the rail (3) and
limit (7), making it free to the transverse movement of
said foil (1) on the displacement device (15).
Figure 5 illustrates a second mode of implementation
of the external position of the sealing element (5), the
use of the rotational device of " command fork" type (10) ,
so that the outline foil (1) is forced against said sealing
(5) element, which in turn touches the flap of said outline
(1) in another outline (9) providing thereby the sealing of
said system.
Figure 6 illustrates a second mode of implementation
of the external position of the sealing element (5), in the
use of the device with transverse displacement with plane
rolling (13), so that the outline foil (1) is forced
against said sealing element (5), which, in turn, touches
the flap of said outline (1) in another outline (9)
providing thereby the sealing of said system.

According to the figure 7, a second mode of
implementation of the set of transverse displacement (15)
is the set of "swingletree" which allows that the weight of
the foil is distributed in a portion (17) of the structure
of said set, which, in turn, is supported on a rigid
vertical element (18), preferably a bar, positioned between
the portion (17) and pulley easel (2). Thus, as described
above and as in figure 4, the set confers a movement of
transverse displacement in the foil (1), so that that it
tilt the rigid vertical element (18) and confer a
rotational movement around its lower end, providing a
displacement of the foil (1) against the sealing element
(5).
Still, compared to other forms of implementation of
the invention, different types of arm devices can be used
for more power for the sealing. But all devices that move
the foil on the, set of longitudinal displacement, more
precisely on the pulleys, have the same principle that is
above described.
Another method envisaged for the completion of this
invention is the set of longitudinal displacement with the
use of pulleys (2) that slide transversally in their own
axis (14), whose axis (14) is greater than the width of
pulleys (2), enabling thereby the transverse displacement
of the foil.
From the example of the preferential embodiment that
has been described, it should be understood that the scope
of this invention covers other forms of implementation, and
is not limited by the content of the claims only, but
included the possible means equivalent, which reach the
CA 02680754 2009-09-14

same proposed technical result and that are substantiated
in this specification.
