Description

"ACTUATION GROUP FOR HANDLING WINDOWS"

DESCRIPTION

The present invention relates to an actuation unit for moving door and window frames.

The invention is particularly suitable for windows of the glazed type or the like.

As is known, to protect from the light coming from outside, or to regulate it, curtains are normally applied in the rooms in correspondence with the glass doors of the windows (windows, French windows, etc.).

This application, which is carried out in various ways and with different forms, is an operation to be performed individually and often turns out to be laborious and specialized.

When movement actuators are associated with the doors and windows, which allow motorized opening and closing of the same, the application of the awnings is made uncomfortable by their presence.

Among the various construction types of movement actuators to be associated with windows, glazed and non-glazed, the most common are the chain ones, and substantially comprise a containing box in which motor means are housed, normally taking the form of an electric motor, connected to a group reducer in turn coupled by means of its toothed wheel, to a guided chain which comes out with one operating end from the containing box and which is connected to the sash, if the box is fixed to the frame of the frame, or to the latter if the box it is fixed to the sash.

In the case of a box fixed to the sash, the application of the awning is particularly inconvenient due to the interference it offers.

This inconvenience is accentuated by the uncomfortable position in which the windows to which the curtains are associated are often located.

For example, windows arranged on attics or dormers may be difficult for an installer to reach; the presence of a window movement actuator, in addition to the difficulty of reaching the window and operating in unstable conditions, make the installation of the awning problematic.

Other difficulties are added when it is necessary to install "motorized" blinds, for example of the roller type, which require electrical connections for their operation; the passage of such cables, in addition to the difficulties described above, makes installation even more difficult.

The aim of the present invention is to solve the problems identified in the installation of window curtains or French windows which can be moved by means of electromechanical actuators.

Within the scope of the aforementioned main task, an important object of the present invention is to provide an actuation unit for the movement of doors and windows which allows to facilitate the installation of a curtain to the door or window with which the actuator is associated.

Another object of the present invention is to provide an actuation assembly for moving window and door frames which allows easy adjustment of the opening and closing of both the window and door frame and of a curtain associated with the window or door.

A further important object of the present invention is to provide an actuation unit for moving door and window frames which is simple to install and easy to use.

These and still other purposes, which will appear more clearly later on, are achieved by an actuation unit for moving window and door frames, of the type comprising an enclosure for containing the electromechanical actuation components and electronic management and control components, characterized by the fact that comprise a roller blind device in turn comprising

- a roller for winding / unwinding the blind,

- means for activating the rotation of said roller,

- unwinding / winding means for at least one cable for maintaining tension of the curtain during its movement,

said roller for winding / unwinding the curtain and said unwinding / winding means for at least one cable being arranged in opposite positions, with respect to the glazed area to be covered, defined on the sash or frame of the window or on both, said roller or said means being constrained to a predisposed position of said casing.

Further characteristics and advantages of the invention will become clearer from the description of a preferred but not exclusive embodiment thereof, illustrated by way of non-limiting example in the accompanying drawings, in which:

It should be noted that everything that in the course of the procedure for obtaining the patent turns out to be already known, is intended not to be claimed and subject to excerpt from the claims.

With reference to the aforementioned figures, an actuation unit for the movement of glazed doors and windows, according to the invention, is indicated as a whole with the number 10.

This actuation unit 10 is for example associated with a window frame S, consisting of a frame T and a leaf B hinged on the upper side with opening towards the outside.

As clearly visible in Figures 2 and 3, this actuation unit 10 consists of a casing 11 for containing the electromechanical actuation components and electronic management and control components, such as an electronic board not shown in the figures.

In this embodiment, this external casing 11 is constituted by a box-like body 12, for example an extrusion (for example in aluminum) with an open transverse profile, inside which two similar actuators 13 of the single chain type (shown unsectioned in Figure 2), each having Γ external operating end 14 of the respective chain arranged to pass through the open portion 15 of the transverse profile of the extruded box-like body 12.

The external envelope 11 has a supporting and covering function for these actuators 13, which are substantially the same and of a known type.

In practice, these actuators 13 are already complete actuators, which can be installed independently of the external casing, according to a known type of structure. For example, the actuators 13 are each made up of a containing box 17 inside which there are (not shown in the figures) motor means connected to a reduction unit in turn coupled by means of a toothed wheel meshing with a guided chain (schematized by a continuous element indicated with 17a) with which it has an external operative end 14 arranged to cross a corresponding opening defined on the containing box (not shown in the figures).

In correspondence with the two extreme portions 18 of the extruded box-like body 12 there are two counter-shaped closing caps 19, also associated for insertion and locked on the extruded box-like body 12 by screws (not shown in the figures).

One of the two closing caps 19 has a cable gland element (not shown in the figures) to let out the power supply and drive wiring of the actuators 13.

Associated with the extruded box-like body 12 are means for covering the open portion 15 of the transverse profile of the extruded box-like body 12, such as, for example, plates of plastic material (not shown in the figures) fixed on the internal portions of the edges of the open portion 15, in particular inserted in opposite slots 20 formed on these edges.

The outer casing 10 has fastening means to the window frame (in this example, to the frame T), such as for example a pair of brackets 21.

According to the invention, the actuation unit 10 comprises a roller blind device 22 in turn comprising a roller 23 for winding / unwinding a blind 24.

Rotation actuation means 25 such as an electric motor 26 are associated with the roller 23.

Furthermore, the roller blind device 22 comprises unwinding / winding means 27 for a cable 28 for maintaining tension of the blind 24 during its movement, which take the form, for example, of a winding pulley 29 to which elastic means are connected. opposition 30 to the unwinding of the cable 28, such as a torsion spring.

This cable 28 is fixed to the free end edge of the curtain 24, for example by means of a hook.

The roller 23 for winding / unwinding the curtain 24 and the unwinding / winding means 27 for the cable 28 are arranged in opposite positions, with respect to the glazed area to be covered, defined on the glazed sash B or on the frame of the window frame T or on both. , as described below.

In fact, in a first configuration, the roller 23 with motor 26 is housed inside the casing 11, in particular within the same compartment 12a of the extruded box-like body 12 in which the actuators 13 are housed (Figures 1, 2, 3, 4, 5 ).

Along the envelope 11 there is a longitudinal slot 11a which allows the exit of the curtain 24.

The pulley 29, on the other hand, is pivoted, by means of its respective clamping element 31, to the frame T of the fixture (or equivalent to the wall to which this frame T is integral), in a position opposite to the casing 11 with respect to the glazed area to be covered with the curtain.

In this configuration, the wiring of the electric motor is internal to the casing 11 and indeed can be connected with the electronic board that controls the actuators, thus defining a single actuation unit with integrated curtain controlled for example by a single command associated with the electronic board, for example by means of a remote control, or a radio control, or alternatively by adding cable controls (in this case different for motor and curtain).

With this configuration, the roller blind device 22 is practically placed integral with the frame T of the door or window.

Figure 4 shows a configuration of a roller blind device, indicated by 122, in which the roller 123 for winding / unwinding the blind 124 with motor 126 is constrained by means of the clamping body 131 to the frame T of the window frame (or equivalently , to the wall to which this frame T is integral), while the pulley 129 is housed inside the casing 111, in particular inside the same compartment of the extruded box-like body 112 in which the actuators 113 are housed (the cable 128 exits from the casing 111 by means of a longitudinal through slot 111 a).

Figure 5 shows a different application configuration of the roller blind device, now indicated with 222, applied to a window with a vasistas opening, towards the inside.

In this configuration, both the casing 211 and the pulley 229 are constrained to the sash B of the window, in correspondence with opposite parts thereof with respect to the glazed area to be shielded with the curtain 224.

In particular, the casing 211 is fixed by means of the brackets 221 on the upper part of the sash B, while the pulley is constrained to it by means of the stabling element 231.

Figure 6 shows a variant relating to the constraint of the pulley, now indicated with 229 '; in this example, said pulley 229 is constrained by means of the clamping element 23 Γ to the frame T of the window frame (or equivalent, to the wall to which said frame T is integral).

Figure 7 shows a variant embodiment of the curtain roller device, now indicated with 322.

In particular, a casing 311 is shown consisting of an extruded box-like body 312 which defines two distinct longitudinal compartments extending parallel to each other, respectively a first compartment 312a for housing the actuators 313 on which the open portion 315 for exiting the chain of the the actuator itself, and a second compartment 312b in which the roller 323 for winding / unwinding the curtain 324 is housed; the longitudinal through slot 31 la is defined on this second compartment 312b.

The second compartment 312b is suitable for housing the winding / unwinding pulley of the cable for maintaining tension of the curtain, in place of the roller 323, when the configuration provides for the roller 323 on the opposite side of the window.

Figure 8 shows a further variant embodiment of the curtain roller device, indicated with 422.

In this embodiment, the casing 411 consists of two distinct bodies, a first box-like body 412, extruded in this embodiment, which defines a first compartment 412a in which the actuators 413 are housed, and a second box-like body 433, extruded in this embodiment, which constitutes a second compartment 433a for housing the roller 423 for winding / unwinding the curtain 424; this second box-like body 433 has a longitudinal through slot 41 la for the exit of the curtain.

Also in this case, the second compartment 412b is suitable for housing the winding / unwinding pulley of the cable for maintaining tension of the curtain, in place of roller 423, when the configuration provides for roller 423 on the opposite side of the window.

This second box-like body 433 is fixed by means of fixing means 434 to the first box-like body 412.

In this embodiment, these fixing means 434 correspond to an insertion coupling of shaped portions 435 of the sides of said second box-like body 433 on corresponding C-shaped counter-shaped portions 436 defined on one face of said first box-like body 412.

It is evident that, in an equivalent manner, the winding / unwinding pulley of the cable for maintaining tension of the curtain can be housed in the second compartment 433a, in place of the roller 423.

It is evident that the means for activating the rotation of the winding / unwinding roller of the blind can also be of the manual type, such as for example the normal flexible cable, rod or belt controls typical of non-motorized roller blind devices.

In practice it has been found that the invention thus described achieves the intended aim and objects.

In fact, the present invention provides an actuation unit to which a roller blind device is integrated.

This integration allows both the installation of the movement actuators and the roller blind device to be carried out at the same time, thus avoiding the secondary installation of the latter, with all the practical problems highlighted in the introduction.

Furthermore, by arranging the winding / unwinding roller with its motor inside the casing containing the actuators and making common electrical connections, the wiring phase is considerably simplified (in practice, a single wiring is obtained instead of two separate wiring). .

The particular structure of the casing defined by an extruded box-like body that contains the actuators and the roller blind (or the pulley with tensioning cable) allows a particular flexibility in sizing the actuation group, as it allows to prepare a casing of the exact size. with respect to the window to be obtained with the number of actuators necessary to support the weight of the window, and to associate, if necessary, the roller blind device.

The invention thus conceived is susceptible of numerous modifications and variations, all falling within the scope of the inventive concept; moreover, all the details can be replaced by other technically equivalent elements.

In practice, the materials used, as long as they are compatible with the specific use, as well as the dimensions, may be any according to the needs and the state of the art.

Where the characteristics and techniques mentioned in any claim are followed by reference marks, such reference marks have been included for the sole purpose of increasing the intelligibility of the claims and consequently such reference marks have no limiting effect on the interpretation of each element. identified by way of example by these reference signs.
