The actuator 12 can? be operated manually by, for example, a switch, or automatically by, for example, a unit? control logic connected to said actuator 12 and configured to activate or deactivate said actuator 12.

In the present embodiment, the actuator 12 is an electric motor. However, in other embodiments, the actuator 12 can? be other than described such as, for example, a hydraulic or pneumatic motor. Furthermore, ? it is possible to envisage manual movements without thereby departing from the scope of protection of the present invention.

The movement group 1 then comprises a first pair of fixing plates 13A, 13B fixed respectively to the two sliding wings F1, F2 of the window F along a first side of the window F and a second pair of fixing plates 14A, 14B fixed respectively to the two sliding shutters F1,F2 of the window F along a second side of the window F opposite the first side.

Pi? in detail, the fixing plates 13A, 13B are arranged in correspondence with the first worm screw 100 and have respective slots 130A, 130B obtained on the fixing plates 13A, 13B for the insertion of the first worm screw 100.

Similarly, the fixing plates 14A, 14B are arranged in correspondence with the second worm screw 110 and have respective slots 140A, 140B obtained on the fixing plates 14A, 14B for the insertion of the second worm screw 110.

Furthermore, the handling unit 1 comprises a first pair of supports 15A, 15B respectively fixed to the first pair of fixing plates 13A, 13B and a second pair of supports 16A, 16B respectively fixed to the second pair of fixing plates 14A, 14B.

In particular, these supports 15A, 15B, 16A, 16B are engaged with the worm screws 100, 110, and associated with the sliding wings F1, F2. How will it be? better described hereinafter, the supports 15A, 15B, 16A, 16B allow, in use, to drag the sliding doors F1, F2 of the window F to open or close the latter.

In the present embodiment these supports 15A, 15B, 16A, 16B are flanged lead nuts. However, in other embodiments, these supports 15A, 15B, 16A, 16B can be different from what is described.

In particular, each nut 15A, 16A has a first thread in such a way as to slide, in use, respectively along said first worm screw 100 towards said second end? 100? and along said second worm screw 110 towards said second end? 110?.

Furthermore, each nut 15B, 16B has a second thread opposite the first thread so as to slide, in use, respectively along said first worm screw 100 towards said first end? 100? and along said second worm screw 110 towards said first end? 110?. The operation of the handling unit 1 described above takes place as follows.

Initially, when the 12 engine? off, the sliding leaves F1, F2 of window F are not moved and, therefore, remain in their position.

Following the manual or automatic activation of the motor 12, the transmission members 120,121 rotate with a first or second direction of rotation and transmit, by means of the respective movement members 10,11, this rotation to the worm screws 100,110.

Pi? in detail, the two transmission members 120,121, connected to the motor 12, drive the respective helical wheels present inside the movement members 10,11 and integral with the respective worm screws 100,110.

In particular, the rotation of the first worm screw 100 involves the translation of the nuts 15A, 15B along the first worm screw 100 while the rotation of the second worm screw 110 involves the translation of the nuts 16A, 16B along the second worm screw 110 .

So, the nuts 15A,15B,16A,16B, since? respectively constrained to said fixing plates 13A,13B,14A,14B, they drag the respective sliding wings F1, F2 into the closed or open position on the basis of the direction of rotation imposed by said transmission members 120,121.

Furthermore, in the embodiment described, the two sliding doors F1, F2 move synchronously along the same movement direction D. However, in other embodiments, the movement of these sliding doors F1, F2 can be different, for example, asynchronous.

Figure 5 shows a further embodiment of the window F according to the present invention.

In particular, the window F comprises an angular frame T in order to allow the installation of the window F in correspondence with two consecutive walls, so as to form an angle, typically an angle equal to approximately 90°.

However, said T-frame can? be made in a different way, without thereby departing from the scope of protection of the present invention. For example, said T frame can? include two adjacent structures at the corner between the two walls.

In this angular configuration, the sliding wings F1, F2 of the window F are able to slide between a closed position and an open position along respective sliding guides (not shown in the figures) obtained on the frame T of the window F.

Pi? in detail, the first F1 sliding door? movable with respect to a first movement direction D1 parallel or substantially parallel to the Z axis of the reference system XYZ while the second sliding wing F2 ? movable with respect to a second movement direction D2 parallel or substantially parallel to the Z axis of the reference system XYZ, and, therefore, parallel to the first movement direction D1.

In the embodiment being described, the window F ? a vertically scrolling angular F window. However, in other embodiments, the window topology F may be different than described.

Furthermore, in the embodiment described, the movement of the sliding doors F1, F2 can occur synchronously.

However, in other embodiments, such handling may be different from what is described, for example the movement of each sliding door F1, F2 can? be independent from the other sliding door F1, F2 in order to partially or totally open or close each sliding door F1, F2.

The structure and operation of the further components of the angular window F shown in Figure 5 are the same as in the previously described embodiment. In particular, as can be seen from figure 5, also in this embodiment, the movement unit 1 of the sliding wings F1, F2 comprises the conversion members 10, 11, the worm screws 100, 110 as well as the the actuator 12 connected to the conversion members 10, 11 by means of respective transmission members or shafts 120, 121, in order to move the sliding wings F1, F2.

Advantages

A first advantage of the sliding window according to the present invention? that of guaranteeing a balance between the sliding doors when the latter are raised and lowered. Furthermore, the movement of the sliding doors along the same movement direction as well as? the hermetic closure of the same allows to increase the thermal and acoustic insulation with respect to solutions of the known type.

A further advantage of the sliding window according to the present invention ? that of reducing the overall dimensions through the use of threaded screws to be placed in the vertical uprights of the window, compared to the common use of counterweights.

Another advantage of the sliding window according to the present invention ? to increase the level of safety through the use of the movement group of the sliding doors. In fact, the movement of the nuts depends on the rotation of the threaded rods, which are powered by the electric motor. Therefore, if the latter is not activated, the shutters of the window remain closed.

A further advantage of the sliding window according to the present invention ? to ensure safe use of the sliding doors. In fact, unlike solutions of the known type which typically employ counterweights with ropes, which are often subject to elongation, fraying and breakage, the present invention comprises flanged nuts made, for example, of bronze, which, by their nature, have a limited wear over time, minimizing or avoiding the risk of sliding doors falling.

Another advantage of the sliding window according to the present invention ? that of providing a movement unit with the same overall dimensions regardless of the size of the window frames to which it is applied.

The present invention ? been described by way of illustration, but not limitation, according to your preferred embodiments, but ? it should be understood that variations and/or modifications may be made by experts in the art without thereby departing from the relative scope of protection, as defined by the attached claims.
