Patent Description:
Both outdoor and indoor installations are known - for example to be mounted in correspondence with windows, doors, glazed windows or other openings in general - which provide for the use of roller blinds. In particular, these installations provide for the use of a motorized shutter which, when open, is wound around a motorized tubular shaft and, when fully or partially closed, is unwound by said shaft, preferably sliding along side guides, to thereby covering all or part of the light from the window, door, glazed window or other opening in general.

The current market requirement is to provide, in correspondence with the roller blind, a roller blind or a roller mosquito net. In particular, for this purpose, a further shaft is also mounted inside the box containing the motorized winding shaft of the shutter, around which the roller blind or mosquito net is wound and unwound. In these known solutions, the spaces inside the housing box for both the roller blind and the roller blind or mosquito net are particularly small and, in particular, the motorisation of the shaft around which the roller blind or mosquito net is wound and unwound is particularly complicated.

Generally, a dedicated motor is used to drive the shaft around which the blackout or mosquito net is wound and unwound. - it is inserted inside the same tree around which the roller blind or mosquito net is wound and unfolded. Furthermore, again with the idea of optimizing the spaces inside the box in which the roller blind winding shaft is also positioned, a shaft with a particularly small diameter is used to roll up/unwind the roller blind or mosquito net and, therefore, the motors used - which, as mentioned, are housed inside the shaft itself - are particularly compact (for example they have a diameter of about <NUM>) and, in the case of smaller dimensions, they have the drawback that they are generally not able to supply an output torque sufficient to cause the rotation of the shaft around which the roller blind or mosquito net is wound/unwound. In particular, in some cases larger motors would be required, which would thus be able to develop a greater output torque, however the dimensions of the shaft around which the roller blind or mosquito net is wound/unwound and/or the installation inside the dumpster do not allow it.

<CIT> describes a drive device for a roller blind and for a roller blind; said device comprises a mechanism which selectively transmits the rotation torque of the actuator to the roller blind winding tube or to the fabric winding tube.

The object of the invention is to propose a device, to be mounted in correspondence with an installation comprising a first rolling group and a second rolling group, and provided for the motorization of the second rolling group, which eliminates or overcomes - at least in part - all the drawbacks which can be found in the known solutions and which, in particular, can be installed in conditions in which the available spaces are reduced.

Another object of the invention is to propose a device to be mounted in correspondence with an installation comprising a roller blind, preferably motorized, to motorise the movement of a blackout/filtering curtain or mosquito net or similar acting on the same window, door, glass wall or opening in which it acts roller blind.

Another object of the invention is to propose a device which allows to move the shaft around which the blackout/filtering curtain or mosquito net is wound or unfolded, optimizing at the same time the installation dimensions inside the box and without the dimensional and performances - present in the known solutions - for the motorisation of said winding/unwinding shaft of the blackout/filtering curtain or mosquito net.

Another object of the invention is to propose a device which is easy to install, even by non-specialised personnel,.

Another object of the invention is to propose a device which is easy to program and manage.

Another object of the invention is to propose a device what could it be also controlled remotely from a smartphone both to control the operation of the control device itself and to verify the correct execution of the commands received.

Another object of the invention is to propose a device which is an improvement and/or alternative to the traditional ones.

Another object of the invention is to propose a device which can be obtained simply, quickly and with low costs.

Another object of the invention is to propose an installation for at least two rolling groups which is particularly small in size, which is simple and quick to assemble and install, easy to program and manage, as well as obtainable in a simple, rapid and low-cost way.

In particular, for this purpose, the transceiver, as well as to control with its receiver side motor <NUM> or to the switching mechanism <NUM> of device <NUM>, with the transmitter side it can transmit signals on the state of the components of the device itself. In essence, or conveniently, in this way the user can remotely control, for example via a mobile phone (preferably via smartphone), the switching on, off and regulation of the motor <NUM> and/or the actuation of the switching mechanism <NUM> to thus bring it into the first or second condition, and therefore actuate the first <NUM> or the second drive module <NUM> respectively, and can receive, again with the mobile phone (preferably a smartphone), information on the current state of the latter.

Advantageously, a first door can be provided on the side wall of the tubular casing <NUM> for accessing the inside of the tubular casing itself from the outside, for example to be able to access - if provided - the rechargeable battery. Advantageously, a second door can also be provided in the tubular shaft <NUM> to access the first door formed in the tubular casing <NUM>. Conveniently, it is intended that the first flap of the tubular casing <NUM> and the second flap of the tubular shaft <NUM> face each other.

The present invention also relates to an apparatus of motorization, to be mounted in correspondence with an installation <NUM> comprising a first motorized rolling group <NUM>, for example a roller blind, and a second rolling group <NUM>, for example a blackout/filtering curtain or mosquito net. In particular, the drive train includes :.

In particular, the second motorized output element <NUM> of the drive device <NUM> emerges from the tubular shaft <NUM> and is actuated in rotation by the motor <NUM> of the device <NUM> and the motion of the second motorized output element <NUM> is transferred, by means of the transmission means <NUM>, to the further member <NUM> which is integral in rotation with the further tubular shaft <NUM>, to thus cause the rotation of the latter around the axis X<NUM>.

The present invention also relates to an installation <NUM> comprising a first rolling group <NUM>, preferably motorized, for example a roller blind, and a second rolling group <NUM>, for example a blackout/filtering curtain or mosquito net, in which the motorisation of the movement of said two rolling groups <NUM> and <NUM> is obtained by means of a device <NUM> as described above.

Conveniently, in the installation <NUM> according to the invention, the drive device <NUM> is mounted inside the tubular shaft <NUM> at the same/single end of the tubular shaft itself.

Conveniently, in the installation according to the invention, the second motorized output element <NUM> of the drive device <NUM> is configured so that its axis of rotation X<NUM> is parallel with respect to the axis of rotation X<NUM> of the tubular shaft <NUM> at the inside which the casing <NUM> of said device <NUM> is inserted and also with respect to the axis of rotation X<NUM> of said further tubular shaft <NUM> to be moved by means of said device <NUM>.

From what was said it is clear that the drive device and/or apparatus according to the invention it is quite advantageous in that it allows the independent motorization of two winding/unwinding shafts of corresponding rolling elements, while optimizing the installation space. Furthermore, with respect to the state of the art, the problems deriving from the dimensional limits, and therefore performance limits, of the motors that can be used are also resolved since, in the solution according to the invention, the single motor of the device <NUM> for moving both shafts is installed inside a single winding/unwinding shaft which is the one with the largest diameter.

The solution according to the present invention has been a described herein in particular with reference to an installation in which the first roller blind assembly is of the roller blind type and the second roller blind assembly is of the a blackout/filtering curtain or mosquito net, however it is understood that it can be used in any other application in which the movement of at least two winding/unwinding shafts for corresponding rolling elements is envisaged.
