Field of application of the invention
[0001] The present invention refers to the field of movable blinds placed inside "double
glazings", i.e. structures comprising at least two mutually parallel glass panes supported
by a frame at least partially interposed therebetween. The glass panes delimit, together
with the frame, an airtight and watertight chamber within which the blind is placed.
Incidentally, instead of glass, the panes can be made of any material at least partially
permeable to light. In the following present description, with the word "glass" it
is intended to identify all the materials of the aforesaid type.
[0002] In particular, the present invention refers to the field of movable blinds placed
inside "triple glazings", i.e. comprising three mutually parallel glass panes that
delimit, together with the frame, two chambers within one of which the blind is placed.
[0003] The movable blinds housable in the double/triple glazings are of various types, for
example: roller blinds, pleated blinds, blinds with vertical strips or with panels,
Venetian blinds, etc. Hereinbelow in the present description, with the expression
"movable blind" it is intended to identify all the blinds of the aforesaid type.
[0004] The movement of a blind placed inside a double/triple glazing occurs by means of
a movement group which can be "active" or "passive".
[0005] The active movement groups themselves generate the motion that causes the movement
of the blind by means of the conversion of other energy forms into mechanical energy.
In particular, the active movement groups comprise an electric motor mechanically
coupled to the blind in a manner such that the actuation of the motor causes the movement
of the blind.
[0006] The passive movement groups lack internal motion sources and are limited to transmitting
to the blind the mechanical energy received from another device. In particular, the
passive movement groups comprise a multiplicity of motion transmission members mechanically
coupled both to the blind and to a device that provides mechanical energy. The mechanical
coupling between the movement group and the blind is such that the supply of mechanical
energy to the movement group causes the movement of the blind.
[0007] Independent of whether it is active or passive, the group for moving the blind must
be mechanically coupled to the blind. The movement group is therefore placed inside
the double/triple glazing. The device by means of which the movement of the blind
is controlled is however placed outside the double/triple glazing since it must be
accessible to a user of the blind. This has made it necessary to use devices capable
of transmitting, to the active or passive movement group, respectively a control signal
or the mechanical energy coming from the control device.
[0008] The present invention has application in reference to blinds moved by passive movement
groups. Hereinbelow in the present description, with the expression "movement group"
it is intended to identify all the movement groups of the aforesaid type (i.e. passive).
[0009] The present invention refers, more precisely, to a device for coupling a group for
moving a blind inside a triple glazing to a device placed outside the triple glazing,
by means of which the actuation of said movement group is controlled. The device,
subject of the invention, therefore transmits mechanical energy from the device with
which the movement of the blind is controlled (outside the triple glazing) to the
blind movement group (inside the triple glazing).
Review of the prior art
[0010] In order to mechanically couple a group for moving a blind placed inside a double
glazing and a device that controls the actuation of the movement group, it is necessary
to penetrate the chamber delimited by the glass panes and by the frame. However, by
operating in such a manner, the seal of the double glazing will be compromised. In
order to solve this problem, said mechanical coupling is achieved magnetically, as
illustrated in the patent application
WO 95/24539 (filed with No.
PCT/IT1994/000121 by the Applicant). In particular, it has been thought to employ a first and a second
magnet which attract each other and lie on opposite sides of a wall of the double
glazing. The first magnet is integrally connected to the control device and is therefore
placed outside the double glazing. The second magnet is integrally connected to the
blind movement group and is therefore placed inside the double glazing. The actuation
of the control device rotates the first magnet which, due to the magnetic coupling,
rotates the second magnet which drives the movement group.
[0011] The abovementioned solution has application in the movable blinds placed inside double
glazings (i.e. comprising a single chamber enclosed between two glass panes) but it
does not allow solving the above problem in the blinds placed inside triple glazings.
In the latter, in fact, the control device usually lies outside the triple glazing
at one of the two peripheral glass panes, and the blind is housed in the chamber enclose
between the intermediate glass pane and the other peripheral glass pane. In other
words, whereas in the double glazings the control device and the blind movement group
are separated by a single wall of the double glazing, in the triple glazings the control
device and the blind movement group are separated by a peripheral glass pane, by the
intermediate glass pane and by the chamber enclosed therebetween. This has made it
necessary to use devices capable of transmitting the motion coming from the control
device through the abovementioned two glass panes and the chamber interposed therebetween,
such that said motion reaches the blind movement group.
[0012] In order to prevent the penetration of the two chambers delimited by the glass panes
and by the frame, compromising the seal of the double/triple glazing, it has been
thought to integrate the above-described solution by housing a third magnet in the
chamber interposed between the control device and the movement group, as illustrated
in the patent application
EP 2 196 615 A2 (filed with No.
09175358.2). In particular, this solution provides for the use of: a first magnet integrally
connected to the control device and therefore placed outside the double/triple glazing;
a second magnet integrally connected to the blind movement group and therefore placed
inside the double/triple glazing in the chamber where the blind is housed; and a third
magnet housed in the chamber interposed between the control device and the movement
group. The first and the third magnet, along with the third magnet and the second
magnet, are attracted to each other, obtaining a mechanical coupling between the control
device and the movement group. The actuation of the control device rotates the first
magnet which, due to the magnetic coupling, rotates the third magnet which, due to
the magnetic coupling, rotates the second magnet which actuates the movement group.
[0013] Even if the abovementioned solution resolves the problem of transmitting mechanical
energy from the control device to the blind movement group, preserving the seal of
the triple glazing, it does not provide any indication regarding the manner in which
the connection is achieved between the third magnet and the triple glazing. Said connection
must be extremely reliable since, if a maintenance operation is necessary, this not
only involves breaking the seal of the triple glazing but would also require the at
least partial disassembly thereof.
Objects of the invention
[0014] Therefore, the object of the present invention is to overcome the aforesaid drawbacks
and to indicate a device that magnetically achieves the aforesaid mechanical coupling
between the magnet of the control device and the magnet of the blind movement group,
and whose connection to the double/triple glazing where the blind is housed is extremely
reliable.
Summary of the invention
[0015] Subject of the present invention is a device for transmitting, to a group for moving
a blind placed inside a double/triple glazing, a rotary motion coming from a device
for controlling the actuation of the movement group, the transmission of the rotary
motion causing the actuation of the movement group;
the control device being placed outside the double/triple glazing; the double/triple
glazing comprising:
- a first chamber in which the blind and the movement group are housed, the first chamber
being partially enclosed between a first peripheral wall and a second intermediate
wall;
- at least one second chamber in which the transmission device is housed, the second
chamber being partially enclosed between the second intermediate wall and a third
peripheral wall, the transmission device being interposed between the second intermediate
wall and the third peripheral wall, the second chamber being interposed between the
first chamber and the control device, the control device being in proximity to the
third peripheral wall;
- means for supporting the transmission device in the second chamber;
the control device comprising a first magnet rotatable around one axis thereof with
respect to the third peripheral wall, the rotation of the first magnet corresponding
with said rotary motion;
the movement group comprising a second magnet rotatable around one axis thereof with
respect to the second intermediate wall, the rotation of the second magnet causing
the movement of the blind;
the transmission device being rotationally and magnetically coupled to the first magnet
and to the second magnet, the rotational magnetic coupling causing the transmission
of said rotation from the first magnet to the second magnet,
wherein according to the invention the support means comprise first elastic means
for connecting the transmission device to the second intermediate wall and to the
third peripheral wall.
[0016] Advantageously, the transmission device is connected not to the frame of the double/triple
glazing, but to the glass panes between which the second chamber is enclosed (i.e.
to said second and third wall). In such a manner, the transmission device is not constrained
to lie in proximity to the frame.
[0017] The glass panes of a double/triple glazing are however often subjected to vibrations
due to stresses, usually of mechanical nature. These stresses occur not only during
assembly of the double/triple glazing, but also after the installation thereof, above
all with regard to the peripheral glass panes (corresponding with said first and third
wall). Due to these high vibrations there is the risk of both damaging the transmission
device, and separating the transmission device from the glass panes to which it is
connected.
[0018] In order to prevent similar occurrences, the means for connecting the transmission
device to the glass panes are elastic. In such a manner these are capable of absorbing
said vibrations without the same compromising the operation of the transmission device
or the connection thereof to the glass panes. Analogously, the first elastic connection
means absorb the movements of the glass panes due to the bending and/or deflections
of the latter caused by temperature changes.
[0019] The use of the first elastic connection means is also extremely advantageous in the
case in which the distance between the glass panes which enclose the second chamber
is, during assembly of the double/triple glazing, slightly different from that indicated
in the technical structural drawings of the double/triple glazing (this can occur,
by way of example, due to the tolerances of spacer profiles which enclose the second
chamber together with the glass panes, or due to the quantity of butyl sealant used
for securing the seal of the double/triple glazing, or due to the application of an
excessive force with which the glass panes are pressed against each other during the
assembly of the double/triple glazing). Due to their elasticity, the first connection
means compensate for said difference, assuring the connection between the transmission
device and the glass panes between which the device is interposed.
[0020] Further innovative characteristics of the present invention are described in the
dependent claims.
[0021] According to one aspect of the invention, the transmission device comprises a containment
structure in which at least one third magnet is housed, the third magnet being connected
to the containment structure by means of second means suitable for allowing the rotation
of the third magnet around one axis thereof with respect to the containment structure;
the first elastic connection means being elastic means for connecting the containment
structure to the second intermediate wall and to the third peripheral wall, the containment
structure being connected to the second intermediate wall and to the third peripheral
wall in a manner such that the third magnet is interposed between the first magnet
and the second magnet;
the first magnet and the third magnet being magnetically attracted to each other,
said magnetic attraction being of size such that the rotation of the first magnet
causes the rotation of the third magnet;
the third magnet and the second magnet being magnetically attracted to each other,
said magnetic attraction being of size such that the rotation of the third magnet
causes the rotation of the second magnet.
[0022] According to another aspect of the invention, the first elastic connection means
comprise at least one first tongue and a second tongue;
the first tongue having at least one first edge and a second edge opposite the first
edge, the first tongue being integrally connected to the containment structure at
least at the first edge, the first tongue being integrally connected to the third
peripheral wall at least at the second edge, a portion of the first tongue starting
from the second edge being non-adherent to the containment structure; the second tongue
having at least one third edge and a fourth edge opposite the third edge, the second
tongue being integrally connected to the containment structure at least at the third
edge, the second tongue being integrally connected to the second intermediate wall
at least at the fourth edge, a portion of the second tongue starting from the fourth
edge being non-adherent to the containment structure.
[0023] Each tongue is therefore connected to the containment structure at least at one edge
thereof starting from which the tongue is lifted from the containment structure to
come into contact with the wall of the double/triple glazing opposite thereto. Due
to the presence of the tongues, an air space is created between the containment structure
and each of the two walls between which it is interposed. The thickness of the air
spaces is such to allow the magnetic coupling between the transmission device and,
respectively, the control device and the movement group. The manner in which the tongues
are connected to the containment structure and to the respective wall to which they
are opposite render the connection elastic between the containment structure and the
second and third wall of the double/triple glazing. When a wall of the double/triple
glazing vibrates, the tongue connected to said wall is deformed, damping the vibration
and preventing the latter from reaching the containment structure. Once the vibration
has terminated, the tongue once again assumes its original configuration, bringing
the containment structure back into the position assumed before the vibration occurred.
[0024] According to another aspect of the invention, the tongues are made of polymethylmethacrylate
(also known with the acronym PMMA).
[0025] According to another aspect of the invention, the second edge and the fourth edge
each lie at a distance from the containment structure comprised between 0.8 mm and
1.2 mm.
[0026] According to another aspect of the invention, the second edge and the fourth edge
each lie at a distance from the containment structure of 1.0 mm.
[0027] According to another aspect of the invention, the containment structure has at least
one first face opposite the third peripheral wall and a second face opposite the second
intermediate wall, the first elastic connection means comprising four said first tongues
interposed between the first face and the third peripheral wall, and four said second
tongues interposed between the second face and the second intermediate wall, the first
tongues being arranged symmetrically two-by-two with respect to the rotation axis
of the third magnet, the second tongues being arranged symmetrically two-by-two with
respect to the rotation axis of the third magnet.
[0028] According to another aspect of the invention, the second intermediate wall and the
third peripheral wall are mutually parallel, the transmission device being connected
to the second intermediate wall and to the third peripheral wall in a manner such
that the rotation axes of the first magnet, of the second magnet and of the third
magnet are orthogonal to the second intermediate wall and to the third peripheral
wall.
[0029] According to another aspect of the invention, the transmission device is connected
to the second intermediate wall and to the third peripheral wall in a manner such
that the rotation axes of the first magnet, of the second magnet and of the third
magnet lie on the same line.
[0030] According to another aspect of the invention, the transmission device comprises a
containment structure in which a third magnet and a fourth magnet integrally connected
to each other are housed, the third magnet and the fourth magnet being connected to
the containment structure by means of third means suitable for allowing the rotation
of the third magnet and of the fourth magnet around one axis thereof with respect
to the containment structure;
the first elastic connection means being elastic means for connecting the containment
structure to the second intermediate wall and to the third peripheral wall, the containment
structure being connected to the second intermediate wall and to the third peripheral
wall in a manner such that the third magnet is opposite the first magnet and the fourth
magnet is opposite the second magnet;
the first magnet and the third magnet being magnetically attracted to each other,
said magnetic attraction being of size such that the rotation of the first magnet
causes the rotation of the third magnet;
the fourth magnet and the second magnet being magnetically attracted to each other,
said magnetic attraction being of size such that the rotation of the fourth magnet
causes the rotation of the second magnet.
[0031] When the device, subject of the invention, comprises only a third magnet, the greater
the distance between the second intermediate wall and the third peripheral wall (i.e.
the thickness of the second chamber), the stronger the magnetic field generated by
the third magnet must be so that there is the magnetic coupling with the first and
the second magnet. Of course, the stronger the magnetic field that must be generated
by the third magnet, the higher the costs for manufacturing the device, subject of
the invention. The above-described variant remedies this drawback, since it provides
for the use of two magnets integrally connected together, respectively mechanically
coupled with the first and the second magnet, and each generating a magnetic field
with intensity less than the magnetic field generated by said third magnet when it
is the only magnet comprised in the device, subject of the invention. In such a manner,
the manufacturing costs are reduced with respect to the case in which the transmission
device comprises only one magnet, still ensuring the rotational coupling between the
control device and the movement group.
[0032] By way of example, it might be better to obtain the device, subject of the invention,
in the version comprising a third and a fourth magnet when the distance between the
second intermediate wall and the third peripheral wall is greater than 12 mm.

Detailed description of several preferred embodiments of the invention
[0034] In the present description, in order to facilitate the exposition, reference is only
made to a preferred embodiment of the invention in which the transmission device is
applied to a Venetian blind placed inside a triple glazing. It must be clear that
the described device is not limited to the aforesaid example but is applicable to
any movable blind housed in a glazing set comprising more than one chamber.
[0035] In particular, the device, subject of the invention, can also be applied in a glazing
set comprising more than two chambers and in which:
- the movable blind is housed in a chamber not adjacent to the movement group; and
- a single chamber is interposed between the movement group and the control device.
[0036] The device, subject of the invention, also has application in a glazing set comprising
three chambers, two of which interposed between the blind movement group and the control
device. In such case, the glazing set encloses a first and a second transmission device
respectively housed in the two chambers interposed between the group for moving the
blind and the control device. The first transmission device (housed in the chamber
adjacent to the movement group) is mechanically coupled to the movement group and
to the second transmission device. Analogously, the second transmission device (housed
in the chamber adjacent to the control device) is magnetically coupled to the control
device and to the first transmission device.
[0037] The device, subject of the invention, finally has application in a glazing set comprising
more than three chambers and wherein more than two chambers are interposed between
the blind movement group and the control device. In particular, by way of example
with reference to the case in which there are three chambers interposed between the
blind movement group and the control device, the glazing set encloses a first, a second
and a third transmission device respectively housed in the three chambers interposed
between the blind movement group and the control device. The first transmission device
(housed in the chamber adjacent to the movement group) is magnetically coupled to
the movement group and to the second transmission device (housed in the chamber adjacent
to the first transmission device on the opposite side from the movement group). The
third transmission device (housed in the chamber adjacent to the control device) is
magnetically coupled to the control device and to the second transmission device.
More generally, a transmission device housed in a chamber non adjacent to the movement
group, nor to the control device is magnetically coupled to the two transmission devices
adjacent thereto.
[0038] In the present description, a figure can also be illustrated with reference to elements
not expressly indicated in that figure but in other figures. The scale and proportions
of the various depicted elements do not necessarily correspond with the actual scale
and elements.
[0039] With reference to the
figures 1 to 4, a system is illustrated comprising a structure 1 known as a "triple glazing" and
comprising three mutually parallel glass panes 2, 3 and 4 supported by a frame 5 partially
interposed therebetween. By way of example, the glass panes 2, 3 and 4 are arranged
vertically and the frame 5 is metallic. Incidentally, the latter can also be made
of other materials, for example plastic or rubber.
[0040] The first glass pane 2 (in peripheral position) and the second glass pane 3 (lying
between the two panes 2 and 4) delimit, together with the frame 5, a first parallelepiped
chamber 6 within which a Venetian blind 7 is placed. The blind 7 comprises a multiplicity
of slats 8 that are movable with respect to the triple glazing 1. By way of example,
the slats 8 are arranged horizontally. The blind 7 is connected to a group 9 whose
actuation causes the movement of the slats 8. In particular, by means of the movement
group 9, the slats 8 can translate parallel to the glass panes 2 and 3 or they can
rotate around a respective longitudinal axis thereof arranged horizontally, by way
of example. The movement group 9 is placed inside the chamber 6, preferably above
the blind 7 (i.e. between the blind 7 and the upper portion of the frame 5 in the
figures).
[0041] The second glass pane 3 and the third glass pane 4 (in peripheral position) delimit,
together with the frame 5, a second parallelepiped chamber 10 within which a device
11 is placed that magnetically attains a mechanical coupling between the movement
group 9 and a device 12 placed outside the triple glazing 1 in order to allow a user
of the blind 7 to control the actuation of the movement group 9, i.e. the movement
of the blind 7.
[0042] The control device 12 is connected to the third glass pane 4 and comprises a first
magnet (not visible in the figures), preferably discoidal, opposite the peripheral
pane 4 and rotatable around an axis orthogonal thereto. The control device 12 further
comprises a cord 13; by pulling such cord, the user of the blind 7 controls the actuation
of the movement group 9. The translation of the cord 13 in one sense or in the opposite
sense causes the rotation of the first magnet respectively in one sense or in the
other. The control device 12 described briefly herein is of substantially known type
and therefore will not be further discussed in more detail.
[0043] The movement group 9 is connected to the frame 5 and comprises a second magnet 14,
preferably discoidal, opposite the intermediate pane 3 and rotatable around an axis
orthogonal thereto. The rotation of the second magnet 14 causes the movement of the
blind 7. The movement group 9 described briefly herein is of substantially known type
and therefore will not be further discussed in more detail.
[0044] The transmission device 11 comprises a container 20 with preferably parallelepiped
shape and having a first base 21, a second base 22 opposite the first base 21 and
four lateral walls 23. The first base 21 is opposite the peripheral pane 4. The second
base 22 is opposite the intermediate pane 3. The lateral walls 23 are preferably arranged
orthogonal to the panes 3 and 4. The container 20 encloses a third magnet 24 (visible
in figure 6), preferably discoidal, interposed between the bases 21 and 22 and preferably
parallel thereto, and rotatable around an axis orthogonal to the bases 21 and 22.
Preferably, the first magnet, the second magnet 14 and the third magnet 24 are mutually
parallel and have the respective rotation axes that lie on the same line. The third
magnet 24 is therefore interposed between the first and the second magnet 14, and
is preferably opposed thereto. The first magnet and the third magnet are magnetically
attracted to each other and the size of the magnetic attraction is such that, at the
mutual distance at which they lie, the rotation of the first magnet causes the rotation
of the third magnet 24. Analogously, the third magnet 24 and the second magnet 14
are magnetically attracted to each other and the size of the magnetic attraction is
such that, at the mutual distance at which they lie, the rotation of the third magnet
24 causes the rotation of the second magnet 14. The third magnet is therefore magnetically
and rotationally coupled both to the first magnet and to the second magnet 14, in
such a manner obtaining a mechanical coupling between the control device 12 and the
movement group 9. With reference to
figures 5 and 6, it is possible to observe that the third magnet 24 has a central hole at which it
is connected to the container 20 through a pair of radial bearings 26. By fitting
the third magnet 24 on the radial bearings 26, the rolling friction has been minimized
that is associated with the rotation of the third magnet 24 with respect to the container
20, so as to ensure considerable longevity of operation for the transmission device
11, subject of the invention. The container 20 is connected to the peripheral pane
4 and to the intermediate pane 3 by means of two respective groups 30 and 31 comprising
four tongues each. The tongues 30 are interposed between the first base 21 of the
container 20 and the peripheral pane 4. The tongues 31 are interposed between the
second base 22 of the container 20 and the intermediate pane 3. By way of example,
the tongues 30 and 31 have a nearly isosceles trapezoid form. Preferably, the tongues
30 are connected to the first base 21 of the container 20 at a first edge 32 corresponding
with the larger base thereof, and are connected to the peripheral pane 4 at a second
edge 33 corresponding with the smaller base thereof. Analogously, the tongues 31 are
connected to the second base 22 of the container 20 at a third edge 34 corresponding
with the larger base thereof, and are connected to the intermediate pane 3 at a fourth
edge 35 corresponding with the smaller base thereof. The tongues 30 and 31 therefore
ensure that the bases 21 and 22 of the container 20 do not adhere respectively to
the peripheral pane 4 and to the intermediate pane 3. By way of example, the first
edge 32 of the tongues 30 is connected to the first base 21 of the container 20 at
the edge 40 thereof common to the first base 21 and to the lateral walls 23. Analogously,
the third edge 34 of the tongues 31 is connected to the second base 22 of the container
20 at the edge 41 thereof common to the second base 22 and to the lateral walls 23.
By way of example, each first edge 32 of the tongues 30 and each third edge 34 of
the tongues 31 is respectively connected to the edges 40 and 41 in a manner so as
to be superimposed on one of the eight vertices of the container 20. The tongues 20
and 21 are preferably arranged symmetrically with respect to a plane of symmetry parallel
to the bases 21 and 22 of the container 20. The tongues 20, along with the tongues
21, are preferably arranged symmetrically two-by-two with respect to an axis of symmetry
orthogonal to the bases 21 and 22 of the container 20. Said axis of symmetry preferably
coincides with the rotation axis of the third magnet 24. Incidentally, instead of
only at the edges 32 and 34, the tongues 30 and 31 can be respectively connected to
the bases 21 and 22 of the container 20 also at a portion of tongue that is extended
starting from said edges 32 and 34. Analogously, instead of only at the edges 33 and
35, the tongues 30 and 31 can be respectively connected to the glass panes 4 and 3
also at a portion of tongue that is extended starting from said edges 33 and 35.
[0045] By way of example, the tongues 30 and 31 are made of polymethylmethacrylate. They
therefore act as elastic means for connecting the container 20 to the glass panes
3 and 4, between which the container 20 is interposed. The thickness of the tongues
30 and 31 is preferably comprised between 0.8 mm and 2.0 mm, and still more preferably
is 1.5 mm. The distance between the edge 33 of the tongues 30 and the first base 21
of the container 20, along with the distance between the edge 35 of the tongues 31
and the second base 22 of the container 20, is preferably comprised between 0.8 mm
and 1.2 mm, and still more preferably is 1.0 mm.
[0046] As can be observed in figure 6, the third magnet 24 and the component of the radial
bearings 26 rotating with respect to the container 20 are not in contact with the
latter. This ensures that the rotation of the third magnet 24 and the rotating component
of the bearings 26 occur without any rubbing against the container 20. The radial
bearings 26 themselves, therefore, bear the thrust to which the third magnet 24 is
subjected in a direction orthogonal to the panes 3 and 4 due to the magnetic attraction
with the first and the second magnet 14.
[0047] With reference to the figure 6, it is also possible to observe that the container
20 comprises two shells 20a and 20b shells mutually opposed along the plane of symmetry
of the container 20 parallel to the bases 21 and 22, and mutually connected to each
other by means of known means. A pin 25 is interposed between the shells 20a and 20b,
preferably parallel to the rotation axis of the third magnet 24. The pin 25 preferably
has a length such to fully traverse the radial bearings 26 along the rotation axis
thereof, projecting beyond such bearings with respect to the panes 3 and 4. The pin
25 contributes to maintaining the two shells 20a and 20b centered with respect to
each other, and is opposed to a possible compression of the container 20 between the
panes 3 and 4. Due to the presence of the pin 25, said compression does not rest on
the bearings 26. Incidentally, the compression opposed by the pin 25 is a compression
due to a force applied nearly at the center of the bases 21 and 22 of the container
20. The compression due to the application of said abovementioned force, with which
the glass panes 3 and 4 are pressed towards each other during the assembly of the
triple glazing 1, is opposed by the lateral walls 23 of the container 20.
[0048] Figure 7 shows a transmission device 50 that differs from the transmission device illustrated
in the preceding figures due to the fact that it comprises, in place of the third
magnet 24, a pair of magnets 51 and 52, preferably discoidal, mutually parallel and
integrally connected to each other. Analogous to the third magnet 24, the magnets
51 and 52 are interposed between the bases 21 and 22, preferably parallel thereto,
and are rotatable around an axes orthogonal to the bases 21 and 22. Preferably, the
first magnet, the second magnet 14 and the magnets 51 and 52 are mutually parallel
and have the respective rotation axes that lie on the same line. The magnet 51 is
opposed to the first magnet of the control device 12. The magnet 52 is opposed to
the second magnet 14 of the movement group 9. The first magnet and the magnet 51 are
magnetically attracted to each other and the size of magnetic attraction is such that,
at the mutual distance at which they lie, the rotation of the first magnet causes
the rotation of the magnet 51. Analogously, the magnet 52 and the second magnet 14
are magnetically attracted to each other and the size of magnetic attraction is such
that, at the mutual distance at which they lie, the rotation of the magnet 52 causes
the rotation of the second magnet 14. The magnets 51 and 52, in addition to being
integrally connected to each other, are therefore magnetically and rotationally coupled
both to the first magnet and to the second magnet 14, in such a manner obtaining a
mechanical coupling between the control device 12 and the movement group 9.
[0049] Analogous to the third magnet 24 of the transmission device 11, the magnets 51 and
52 are connected to the container 20 through a pair of radial bearings 54 traversed
by a pin 53 analogous to the pin 25 of the container 20.
