Definitions
- 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.
- the panes can be made of any material at least partially permeable to light.
- glass it is intended to identify all the materials of the aforesaid type.
- 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.
- 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.
- roller blinds for example: roller blinds, pleated blinds, blinds with vertical strips or with panels, Venetian blinds, etc.
- movable blind it is intended to identify all the blinds of the aforesaid type.
- the movement of a blind placed inside a double/triple glazing occurs by means of a movement group which can be "active” or "passive".
- 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.
- 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.
- the passive movement groups lack internal motion sources and are limited to transmitting to the blind the mechanical energy received from another device.
- 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.
- 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.
- the present invention has application in reference to blinds moved by passive movement groups.
- movement group it is intended to identify all the movement groups of the aforesaid type (i.e. passive).
- 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).
- 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.
- 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.
- the control device and the blind movement group are separated by a single wall of the double glazing
- 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 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.
- 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.
- 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:
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- the tongues are made of polymethylmethacrylate (also known with the acronym PMMA).
- 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.
- the second edge and the fourth edge each lie at a distance from the containment structure of 1.0 mm.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- the device subject of the invention, can also be applied in a glazing set comprising more than two chambers and in which:
- the device also has application in a glazing set comprising three chambers, two of which interposed between the blind movement group and the control device.
- 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.
- 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.
- 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.
- 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
- 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.
- a system 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.
- the glass panes 2, 3 and 4 are arranged vertically and the frame 5 is metallic.
- the latter can also be made of other materials, for example plastic or rubber.
- the blind 7 comprises a multiplicity of slats 8 that are movable with respect to the triple glazing 1.
- the slats 8 are arranged horizontally.
- the blind 7 is connected to a group 9 whose actuation causes the movement of the slats 8.
- 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).
- the second glass pane 3 and the third glass pane 4 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.
- 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.
- 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 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.
- 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.
- 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.
- the third magnet 24 has a central hole at which it is connected to the container 20 through a pair of radial bearings 26.
- 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 31 are interposed between the second base 22 of the container 20 and the intermediate pane 3.
- the tongues 30 and 31 have a nearly isosceles trapezoid form.
- 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.
- 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.
- 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.

- 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.
- 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 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 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.

- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.

Description
- 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.
- 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.
- 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.
- The movement of a blind placed inside a double/triple glazing occurs by means of a movement group which can be "active" or "passive".
- 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.
- 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.
- 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.
- 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).
- 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).
- 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 PCT/IT1994/000121 - 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.
- 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 - 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.
- 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.
- 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;
- 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.
- 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.
- 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.
- 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.
- Further innovative characteristics of the present invention are described in the dependent claims.
- 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. - 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. - 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.
- According to another aspect of the invention, the tongues are made of polymethylmethacrylate (also known with the acronym PMMA).
- 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.
- 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.
- 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.
- 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.
- 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.
- 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. - 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.
- 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.
- Further objects and advantages of the present invention will be clearer from the following detailed description of an embodiment thereof and from the enclosed drawings, given as merely exemplifying and non-limiting, in which:

figure 6 shows the transmission device offigure 5 in schematic cross section; -
figure 7 shows, in schematic cross section, a variant of the transmission device offigure 5 . - 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.
- 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.
- 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.
- 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.
- 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.
- With reference to the
figures 1 to 4 , a system is illustrated comprising astructure 1 known as a "triple glazing" and comprising three mutuallyparallel glass panes frame 5 partially interposed therebetween. By way of example, theglass panes frame 5 is metallic. Incidentally, the latter can also be made of other materials, for example plastic or rubber. - 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 theframe 5, a first parallelepiped chamber 6 within which aVenetian blind 7 is placed. The blind 7 comprises a multiplicity ofslats 8 that are movable with respect to thetriple glazing 1. By way of example, theslats 8 are arranged horizontally. The blind 7 is connected to agroup 9 whose actuation causes the movement of theslats 8. In particular, by means of themovement group 9, theslats 8 can translate parallel to theglass panes 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 theframe 5 in the figures). - The
second glass pane 3 and the third glass pane 4 (in peripheral position) delimit, together with theframe 5, asecond parallelepiped chamber 10 within which adevice 11 is placed that magnetically attains a mechanical coupling between themovement group 9 and adevice 12 placed outside thetriple glazing 1 in order to allow a user of the blind 7 to control the actuation of themovement group 9, i.e. the movement of the blind 7. - The
control device 12 is connected to thethird glass pane 4 and comprises a first magnet (not visible in the figures), preferably discoidal, opposite theperipheral pane 4 and rotatable around an axis orthogonal thereto. Thecontrol device 12 further comprises acord 13; by pulling such cord, the user of the blind 7 controls the actuation of themovement group 9. The translation of thecord 13 in one sense or in the opposite sense causes the rotation of the first magnet respectively in one sense or in the other. Thecontrol device 12 described briefly herein is of substantially known type and therefore will not be further discussed in more detail. - The
movement group 9 is connected to theframe 5 and comprises asecond magnet 14, preferably discoidal, opposite theintermediate pane 3 and rotatable around an axis orthogonal thereto. The rotation of thesecond magnet 14 causes the movement of the blind 7. Themovement group 9 described briefly herein is of substantially known type and therefore will not be further discussed in more detail. - The
transmission device 11 comprises acontainer 20 with preferably parallelepiped shape and having afirst base 21, asecond base 22 opposite thefirst base 21 and fourlateral walls 23. Thefirst base 21 is opposite theperipheral pane 4. Thesecond base 22 is opposite theintermediate pane 3. Thelateral walls 23 are preferably arranged orthogonal to thepanes container 20 encloses a third magnet 24 (visible infigure 6 ), preferably discoidal, interposed between thebases bases second magnet 14 and thethird magnet 24 are mutually parallel and have the respective rotation axes that lie on the same line. Thethird magnet 24 is therefore interposed between the first and thesecond 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 thethird magnet 24. Analogously, thethird magnet 24 and thesecond 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 thethird magnet 24 causes the rotation of thesecond magnet 14. The third magnet is therefore magnetically and rotationally coupled both to the first magnet and to thesecond magnet 14, in such a manner obtaining a mechanical coupling between thecontrol device 12 and themovement group 9. With reference tofigures 5 and 6 , it is possible to observe that thethird magnet 24 has a central hole at which it is connected to thecontainer 20 through a pair ofradial bearings 26. By fitting thethird magnet 24 on theradial bearings 26, the rolling friction has been minimized that is associated with the rotation of thethird magnet 24 with respect to thecontainer 20, so as to ensure considerable longevity of operation for thetransmission device 11, subject of the invention. Thecontainer 20 is connected to theperipheral pane 4 and to theintermediate pane 3 by means of tworespective groups tongues 30 are interposed between thefirst base 21 of thecontainer 20 and theperipheral pane 4. Thetongues 31 are interposed between thesecond base 22 of thecontainer 20 and theintermediate pane 3. By way of example, thetongues tongues 30 are connected to thefirst base 21 of thecontainer 20 at afirst edge 32 corresponding with the larger base thereof, and are connected to theperipheral pane 4 at asecond edge 33 corresponding with the smaller base thereof. Analogously, thetongues 31 are connected to thesecond base 22 of thecontainer 20 at athird edge 34 corresponding with the larger base thereof, and are connected to theintermediate pane 3 at afourth edge 35 corresponding with the smaller base thereof. Thetongues bases container 20 do not adhere respectively to theperipheral pane 4 and to theintermediate pane 3. By way of example, thefirst edge 32 of thetongues 30 is connected to thefirst base 21 of thecontainer 20 at theedge 40 thereof common to thefirst base 21 and to thelateral walls 23. Analogously, thethird edge 34 of thetongues 31 is connected to thesecond base 22 of thecontainer 20 at theedge 41 thereof common to thesecond base 22 and to thelateral walls 23. By way of example, eachfirst edge 32 of thetongues 30 and eachthird edge 34 of thetongues 31 is respectively connected to theedges container 20. Thetongues bases container 20. Thetongues 20, along with thetongues 21, are preferably arranged symmetrically two-by-two with respect to an axis of symmetry orthogonal to thebases container 20. Said axis of symmetry preferably coincides with the rotation axis of thethird magnet 24. Incidentally, instead of only at theedges tongues bases container 20 also at a portion of tongue that is extended starting from saidedges edges tongues glass panes edges - By way of example, the
tongues container 20 to theglass panes container 20 is interposed. The thickness of thetongues edge 33 of thetongues 30 and thefirst base 21 of thecontainer 20, along with the distance between theedge 35 of thetongues 31 and thesecond base 22 of thecontainer 20, is preferably comprised between 0.8 mm and 1.2 mm, and still more preferably is 1.0 mm. - As can be observed in
figure 6 , thethird magnet 24 and the component of theradial bearings 26 rotating with respect to thecontainer 20 are not in contact with the latter. This ensures that the rotation of thethird magnet 24 and the rotating component of thebearings 26 occur without any rubbing against thecontainer 20. Theradial bearings 26 themselves, therefore, bear the thrust to which thethird magnet 24 is subjected in a direction orthogonal to thepanes second magnet 14. - With reference to the
figure 6 , it is also possible to observe that thecontainer 20 comprises twoshells container 20 parallel to thebases pin 25 is interposed between theshells third magnet 24. Thepin 25 preferably has a length such to fully traverse theradial bearings 26 along the rotation axis thereof, projecting beyond such bearings with respect to thepanes pin 25 contributes to maintaining the twoshells container 20 between thepanes pin 25, said compression does not rest on thebearings 26. Incidentally, the compression opposed by thepin 25 is a compression due to a force applied nearly at the center of thebases container 20. The compression due to the application of said abovementioned force, with which theglass panes triple glazing 1, is opposed by thelateral walls 23 of thecontainer 20. -
Figure 7 shows atransmission device 50 that differs from the transmission device illustrated in the preceding figures due to the fact that it comprises, in place of thethird magnet 24, a pair ofmagnets third magnet 24, themagnets bases bases second magnet 14 and themagnets magnet 51 is opposed to the first magnet of thecontrol device 12. Themagnet 52 is opposed to thesecond magnet 14 of themovement group 9. The first magnet and themagnet 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 themagnet 51. Analogously, themagnet 52 and thesecond 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 themagnet 52 causes the rotation of thesecond magnet 14. Themagnets second magnet 14, in such a manner obtaining a mechanical coupling between thecontrol device 12 and themovement group 9. - Analogous to the
third magnet 24 of thetransmission device 11, themagnets container 20 through a pair ofradial bearings 54 traversed by apin 53 analogous to thepin 25 of thecontainer 20. - On the basis of the description provided for a preferred embodiment, it is obvious that some changes can be introduced by the man skilled in the art without departing from the protective scope of the invention as defined by the following claims.
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;
