• the above mentioned opening is a window F designed to be opened and closed by a pair of leaves A mounted in a mobile manner on wall P, close to the opposite sides of window F.

• the system according to the invention is not only applicable to the opening and closing of window leaves, it can also be suited to perform the opening and closing of leaves associated to doors or other openings obtained on a generic wall.
• each of leaves A is mounted so as to pivot, in particular by means of hinging means, on wall P.
• the structure of leaf A mounted on wall P is preferably of the casement type; though, the system according to the present invention is also suited to be used on leaves of a different type, for example of the so-called "Padovana” type (in other words, with leaf portions which are foldable relative to one another and tiltable towards the outside of opening F) . If necessary, with the help of a suitable drive mechanism, the system can also be applied to sliding leaves, for example, "disappearing" into wall P.
• leaves A are solid shutters, i.e. they are made of solid panels without opening; alternatively, the leaves can be louvered shutters, in other words with openings allowing light from the outside to come through.
• the openings or louvers in said louvered shutters can be obtained by means of a plurality of transverse slats, which are arranged in a parallel way one under the other and are slightly inclined relative to the plane defined by the leaf itself.
• system 10 comprises:
• an actuator or motor device 14 to be mounted on wall P close to opening F, preferably by means of a support structure 12 which is suited to support it or on which it can be hung;
• a rotary element 16 for example an arm, to be constrained to leaf A and which can be caused to rotate around an operating axis X-X by means of the actuator or motor device 14, so as to cause leaf A to move in order to open and/or close opening F;
• an electric battery 70 which is able to supply power to said actuator or motor device 14.

• system 10 is not connected to the mains, for example the domestic mains supply, and therefore electric battery 70 supplies power to actuator or motor device 14 in order to move leaf A.
• electric battery 70 supplies power to actuator or motor device 14 in order to move leaf A.
• a battery of the 22.2V, 4.4Ah LIPO (lithium-polymer) type for example, in this case it turns out to be advantageous to use a battery of the 22.2V, 4.4Ah LIPO (lithium-polymer) type.

• the connection system can provide suitable switching means, which are able to control the electrical connection between motor 14 and the mains or battery 70, preferably in a selective manner.
• said switching means are suited to connect motor 14 to the mains, thus supplying power to motor 14 from the mains supply.
• they are suited to connect motor 14 to battery 70, which is able to solve this drawback by supplying power to motor 14.
• battery 70 takes on an auxiliary function by ensuring the necessary power supply to actuator or motor device 14, thus allowing the user to perform the opening/closing operations of leaf A without having to interfere with the unlocking system in order to manually move said leaf A.
• actuator or motor device 14 is mounted in correspondence to the top edge or "lintel" of opening F.
• said actuator or motor device 14 is fixed on wall P by means of a support structure 12 manufactured as a metal profile preferably having mounting holes (with no reference numbers), which allow it to be fixed on wall P by means of screws; in particular, in order to fix support structure 12 to wall P, it is possible to use a jig or template M having guide holes (with no reference numbers) arranged in positions corresponding to the above mentioned mounting holes.
• actuator or motor device 14 substantially hangs from support structure 12, for example it is fixed on the latter by means of screws.

• a known battery-charger device for charging electric battery 70 directly in battery-carrier module 72, without having to extract said battery 70 and charge it separately.
• the solution according to which module 72 is removable from system 10 turns out to be particularly useful in case said battery-carrier 72 is associated to the battery-charger, since battery 70 charging operation can be simply and quickly performed by a user, who can remove module 72 first, and then perform the charging operation separately from system 10. In this way the user can extract module 72, with battery 70 inside, from system 10 and charge it.

• Box- shaped elements 19 can also be arranged one next to the other and include intermediate profiled segments, for example with a C-shaped cross section, so as to enclose actuator or motor device 14, thus protecting it like a "shell” against external agents, such as dust, dampness, heat, etc.
• said casing 19 is configured in such a way that battery-carrier module 72 is accessible from the outside, without the need to remove part of casing 19.
• casing 19 can be made up of different parts, among which battery-carrier 72, which can be connected to one another in a removable manner and separated from one another, each independently of the others.
• casing 19 comes to an end in correspondence to its part comprising or making up battery-carrier 72, which therefore remains visible from the outside and easily reachable.
• casing 19 covers battery-carrier 72 at least partially.

• driving portion 20 and driven portion 22 are distinct from the associated actuator or motor device 14 and from associated rotary element 16.
• said solution is less preferred in terms of maintenance of the system, since it is normally necessary to replace the whole output shaft or the whole rotary element in the event of a failure or fault of the driving portion or of the driven portion .
• driving portion 20 and driven portion 22 are mutually movable in a guided manner parallel to rotation axis X-X between the engaged condition, in which they are arranged close to one another and cooperate in rotation with one another, and the disengaged condition, in which they are far from one another and mutually independent in rotation.
• driving portion 20 and driven portion 22 when driving portion 20 and driven portion 22 are in the engaged condition and in the disengaged condition, they are mutually in contact, preferably in the direction of rotation axis X-X, and, respectively, spaced apart, preferably in the direction of rotation axis X-X.
• driving portion 20 and driven portion 22 have an interface with respective contact surfaces 24 and 26, which face one another, for example axially, have a substantially matching shape, and are adapted to engage one another in different coupling configurations corresponding to said mutual arrangements.

• head socket screws 31 are tightened against the periphery of output shaft 15, being preferably inserted into hollows (with no reference number) transversally obtained therein. This coupling helps prevent the undesired translational movement of driving portion 20 relative to output shaft 15.
• driven portion 22 has an axial through opening 36 passed through by output shaft 15, so as to allow a relative rotation between driven portion 22 and output shaft 15; in other words, driven portion 22 and output shaft 15 are coupled in a turning manner through axial through opening 36.

More in detail, contact surfaces 24 and 26 are kept mutually axially coupled due to the thrust exerted by the lobed portion of cam profile 50 provided by control member 48. Therefore, in the engaged condition, output shaft 15 is integral - so as to rotate therewith - to rotary element or arm 16. Clearly, based on the direction of rotation generated by motor 14, leaves A move towards a partially or completely open condition (figure 1) or towards a partially or completely close condition (not shown) .
• control member 48 will bring surfaces 24 and 26 of driving portion 20 and driven portion 22 back into contact, thanks to the thrust exerted by the lobed portion of cam profile 52.
