[0035] FIG. 3 is a block diagram illustrating the operation of a portion of the insulated glazing unit of FIG. 1.

DETAILED DESCRIPTION

[0036] Referring to the annexed figures, 1 generally designates an insulated glazing unit of the present invention.

[0037] The insulated glazing unit comprises a frame 2 that allows it to be inserted in a seat of a wall (not shown) or anchored to the structure of a building (not shown).

[0038] The frame 2 comprises a pair of uprights 3a, a lower cross member 3b and an upper cross member 3c. The cross members 3b, 3c are connected to both uprights 3a. Preferably, the frame 2 is formed with extruded plastic material, or extruded foamed material.

[0039] At least two panes 4, which are at least partly transparent, are associated with the frame 2. Such panes 4 may be for example glass panes.

[0040] In one embodiment, two glass panes may be provided, but in other embodiments, three, four or more glass panes may be also provided.

[0041] In any case, the frame 2 acts as spacers for the glass panes 4.

[0042] The shape and dimensions of the panes 4 as well as those of the frame 2 can be of conventional type and will not be further described.

[0043] When the panes 4 are associated with the frame 2, in a manner known per se and not further described, they define a gap 5. It should be noted here that the association between the frame 2 and the panes 4 is sealed, so that the gap 5 may be isolated from the outside environment.

[0044] Particularly referring to FIG. 1, the insulated glazing unit 1 comprises screening means 6 located inside the gap 5.

[0045] The screening means 6 can be deployed at least between a retracted configuration and a deployed configuration. In the retracted configuration, the screening means 6 are placed proximate to the upper portion of the frame 2, i.e. proximate to the cross member 3C whereat a box 21 is usually provided. In this configuration, the screening means 6 allow the passage of light through the gap 5.

[0046] In the deployed configuration, the screening means 6 are fully extended and their bottom 6A is placed proximate to the lower portion of the frame 2, i.e. proximate to the cross member 3b. In this configuration, the screening means 6 block at least partially or entirely the passage of light through the gap 5, as required by the user.

[0047] It should be noted that the terms upper portion and lower portion of the frame 2 are referred to the state in which the insulated glazing unit 1 is in its position in the seat of the wall, i.e. a state of operation thereof.

[0048] In one embodiment, the screening means 6 consist a blind 7, which may be for example a Venetian blind, a roller blind or a pleated blind. In alternative embodiments of the invention, not shown, the screening means 6 may be of any type known to the skilled person.

[0049] Actuator means 8 are associated with the screening means 6, to alternate them at least between the retracted configuration and the deployed configuration. The particular type of actuator means 8 will be variable according to the type of screening means 6 in use.

[0050] For example, the actuator means 8 may be placed in the box 21 and may comprise a roller operatively driven by an electric motor 8a as well as cords 8b and ladders 8c suitably connected to the screening means 6 and to the roller.

[0051] It should be noted that the electric motor 8a may be of any type known to the skilled person and in particular may be one of those described in other patents and/or patent applications by the Applicant hereof. Therefore, the actuator means 8 will not be further described.

[0052] The insulated glazing unit 1 further comprises power supply means 13, which are operably connected to the electric motor 8a of the actuator means 8.

[0053] For this purpose, the power supply means 13 comprise a stationary portion 14 and a moving portion 15.

[0054] In one aspect, the stationary portion 14 comprises one or more electric cables 14a and a support 14b, the electric cables 14a being adapted to electrically connect the support 14b to the electric motor 8a.

[0055] On the other hand, the moving portion 15 of the power supply means 13, consists of a battery or a battery module 16, which is adapted to be electrically connected/disconnected to/from the stationary portion 14.

[0056] In particular, the battery module 16 is adapted to be electrically connected/disconnected to/from the support 14b.

[0057] For this purpose, the support 14b is specially shaped to house and/or support the battery 16.

[0058] More particularly, the support 14b is associated with the insulated glazing unit 1 and, preferably, is attached to the door or window frame or to the panes 4 (as shown in FIG. 1).

[0059] The support 14b is attached to the frame 2 by mechanical means (e.g. screws) and/or by bonding means (e.g. a double-sided adhesive), but if the support 14b is attached to the panes 4 a bonding attachment is provided (e.g. by a double-sided adhesive).

[0060] In one aspect, the electric cable 14a is preferably arranged inside the frame 2 or in any case is designed to be inaccessible to the user.

[0061] More in detail, the support 14b comprises a first electric connector 18a. The battery 16 comprises a second electric connector 18b, which can be coupled to the first electric connector 18a on the support 14a, in particular when the battery 16 is connected to the support 14a. Further details about the electric connectors 101 will be provided hereinbelow.

[0062] The insulated glazing unit 1 comprises a control unit 9 which has the function of controlling the alternation of the screening means 6 at least between the retracted configuration and the deployed configuration.

[0063] For comprehensive and understandable description, the control unit 9 will be divided into several functional modules. This division does not necessarily reflect the hardware implementation of the control unit 9, which may be of any type.

[0064] It should be noted that, as more clearly explained hereinafter, the modules of the control unit 9 are not necessarily located in the same component.

[0065] The control unit 9 is in signal communication with the electric motor 8a of the actuator means 8, such that it may switch it on and off thereby controlling the movement of the screening means 6.

[0066] The insulated glazing unit 1 comprises an active electronic circuit 12 which is in signal communication with the control unit 9 and is configured to store at least the identification data of the control unit 9.

[0067] In order to provide interfacing with the active electronic circuit 12, the control unit 9 comprises a read/write module 19.

[0068] In particular, according to a particular aspect of the present description, the active electronic circuit 12 is associated with the stationary portion 14 of the power supply means 13.

[0069] The term associated means placed in contact (directly or with the interposition of an additional element) with the stationary portion 14 of the power supply means 13.

[0070] In other words, the electronic circuit 12 is not associated with the moving portion 15 of the power supply means 13.

[0071] Since the active electronic circuit 12 is associated with the stationary portion 14 of the power supply means 13, the identification data of the control unit 9 is advantageously stored in a portion of the insulated glazing unit 1 which shares the fate of the insulated glazing unit itself and not that of the battery 16.

[0072] Preferably, the active electronic circuit 12 is a non-volatile memory, namely of EEPROM type.

[0073] It should be noted that the active electronic circuit 12, i.e. the memory, is readable/writable when it is powered, and maintains the stored data even when the insulated glazing unit 1 is not powered, for example during replacement of the battery 16.

[0074] In the preferred embodiment, the active electronic circuit 12 is integrated in the support 14b of the power supply means 13. This arrangement is particularly advantageous because it minimizes the distance required to power the active electronic circuit 12, to enable reading and writing of the stored data.

[0075] Preferably the read/write module 19 is integrated in the support 14b of the power supply means 13.

[0076] For this purpose, the read/write module 19 comprises respective data connectors 20a, 20b. In particular, the first data connector 20a is electrically connected with the active electronic circuit 12, i.e. the memory, whereas the second data connector 20b is connected to the moving portion 15 of the power supply means 13, i.e. to the battery 16. These data connectors 20a, 20b are embodied by respective pins which electrically contact each other when the battery 16 is electrically connected to the stationary portion 14b of the power supply means 13.

[0077] In an alternative embodiment, not shown, the data connectors 20a, 20b may be replaced with RFID or NFC communication modules, not shown. These modules, which are well-known to the skilled person, provide wireless proximity communication. Here, the control unit 9 comprises a first RFID or NFC communication module connected to the active electronic circuit 12 and inserted in the support 14b. A second RFID or NFC communication module is connected to the read/write module 19 and is inserted in the battery 16. The RFID or NFC modules are in such positions that, when the battery 16 fits on the support 14b, they can communicate with each other.

[0078] Alternatively, the active electronic circuit 12 might be integrated in the box 21 or in the frame 2.

[0079] These arrangements of the active electronic circuit 12 also fulfill the purpose of storing the identification data of the control unit 9 in an electronic circuit that shares the fate of the insulated glazing unit, although they might require an additional electric connection (not shown), or the use of the powerline technology, with the electric cable 14a being used to power the active electronic circuit 12 when reading and writing the stored data.

[0080] More in detail, the control unit 9 comprises a control interface 22 for controlling the motor 8a of the actuator means.

[0081] In a preferred embodiment, the control interface 22 comprises a control section 24 and/or a control element 11.

[0082] The control section 24 is formed on a surface of the battery 16, in particular the surface that can be accessed by the user even when the battery is housed on the fixed support 14b

[0083] The control section 24 is of tactile or touch-sensitive type or consists of a switch or similar devices. For example, also with reference to FIG. 1, the tactile section is embodied by two arrows, indicating two opposite directions to illustrate the possible movements of the screening means 6, once one of these arrows has been touched by the user.

[0084] The control element 11 is a radio control device, for example grasped or held in the hand of a user, which is well known and will not be described herein.

[0085] An interface 22 having both the tactile section 24 and the radio control 11 affords easier and more convenient management of the movement of the screening means 6 by the user, who can directly control them proximate to the glass unit by acting on the tactile section (with the battery 16 housed on the fixed support 14b) and/or far from the insulated glazing unit through the radio control 11.

[0086] In order to be coupled with the control element 11, the insulated glazing unit 1 comprises receiving means 10 which are configured to receive data via wireless signal communication, in particular via a radio-frequency, infrared, Bluetooth, Zigbee connection or in any other manner known to the skilled person.

[0087] The active electronic circuit 12, as mentioned above, is able to store at least data concerning the control unit 9 and in particular data concerning the control element 11, such as the radio communication channel used by the radio control for interfacing.

[0088] More in detail, the active electronic circuit 12 is designed to store any kind of data useful for operation of the insulated glazing unit 1. Such data may be preferably but without limitation related to one or more of the following parameters: [0089] azimuth of the screening means 6; [0090] geographic location of the insulated glazing unit 1; [0091] location of the insulated glazing unit 1 inside a building; [0092] type of screening means 6; [0093] size and/or the type of electric motor 8a; [0094] speed of movement of the screening means 6; [0095] time or mechanical coefficients to be used to ensure synchronous movement with other screening means 6; [0096] positioning of the screening means 6 with respect to the box 21 and/or the cross member 3b; [0097] admitted operation mode of the screening means 6.

[0098] In one aspect, the receiving module 10 is preferably integrated in the battery 16, or in the moving portion 15 or the stationary portion 14 of the power supply means.

[0099] The active electronic circuit 12 is in signal communication at least with the receive/transmit module 10 and has the purpose of storing at least identification data of a control element 11.

[0100] In one aspect, the power supply means 13 comprise one or more photovoltaic panels 23. For this purpose, the stationary portion 14 comprises an electric connection 14c for electrical communication between the support 14b and the photovoltaic panel/s 23.

[0101] A skilled person may obviously envisage a number of equivalent changes to the above discussed variants, without departure from the scope as defined by the appended claims.
