DESCRIPTION OF THE PREFERRED EMBODIMENTS

With reference to the number references of the above mentioned figures, the improved safety device for door-window handles and the like according to the present invention, which has been generally indicated by the reference number 1, comprises a plate 2 which is preferably so designed as to mate the contour or profile of a base or bottom 3 of a handle 4.
Said plate 2 comprises a throughgoing hole 5 therethrough passes the contoured pivot pin 6 of the handle 4.
Said contoured or shaped pivot pin 6 usually has a quadrangular cross section and engages with an opening mechanism of the door-window, in a per se known way.
According to the present invention, the safety device plate 2 comprises, at said throughgoing hole 5, a recess or seat 7 for engaging therein a rotary body 8 having a contoured hole 9 corresponding to the shape of the shaped pivot pin 6, in this case a quadrangular configuration.
The rotary body 8 has a circular configuration and turns together with the contoured pivot pin 6 in said recess 7, also having a substantially circular shape, but with an open side 10.
The rotary body 8 comprises moreover a cut-out 11 interrupting its circular profile.
The safety device 1, according to the present invention, comprises moreover a locking element, having at least two operating positions: a closed operating position, thereat it prevents the handle 4 from rotating, by interfering against the profile of the rotary body 8, and an open operating position, thereat said locking element does not hinder the rotary movement of the rotary body 8 thereby the handle 4 may be rotated.
Preferably, said locking element comprises a rod 12 slidingly engaged in a tangential seat 13 of the plate 2 tangentially of the recess 7 of the rotary body 8 and communicating with said recess 7.
Said rod 12 comprises an enlarged portion 14 allowing said rod 12 to be driven in a tangential seat 13 through a movement range defined by an enlarged region 15 of the tangential seat or recess 13.
In a closed position, said rod 12 interferes against the cut-out 11 of the contour or profile of the rotary body 8, as clearly shown in Figures 2 and 5, thereby preventing the contoured pivot pin 6 of the handle 4 from rotating.
In the open position, shown in Figures 3 and 6, the rod 12 is removed from the open side 10 region of the recess 7 thereby allowing the rotary body 8 to freely rotate in said recess 7, and in turn allowing the handle 4 and related contoured pivot pin 6 to rotate to drive the door-window to an open position.
Advantageously, the rod 12 comprises a small lug 16 facilitating the gripping and displacement of the rod.
The safety device 1 according to the present invention may be clamped to existing handles by several clamping systems, for example screws, glue materials, and so on, by arranging the plate 2 between the base or bottom 3 of the handle 4 and the surface 17 of the door-window.
Figures 7 and 8 show an improved safety device, according to a further aspect of the present invention, and generally indicated by the reference number 101, comprising a plate 102.
Said plate 102 comprises a pair of perimetrical elements, indicated by the reference numbers 112 and 122 respectively, which are mutually interexchangeable and allow the plate contour or profile to be fitted to the base profile of a handle.
More specifically, said plate 102 comprises a throughgoing hole therethrough the shaped pivot pin 106 of the handle extends.
The shaped pivot pin 106 usually comprises a quadrangular cross-section and engages the door-window opening mechanism, in a per se known way.
According to the present invention, the device plate 102 comprises, at said throughgoing hole, a seat or recess for a rotary body 108, including a contoured hole, corresponding to the shape of the contoured pivot pin 106, in this embodiment a quadrangular shape.
The rotary body 108 has a circular configuration and turns, rigidly with said contoured pivot pin 106, in said seat, also having a substantially circular configuration, but with an open side, as in the hereinabove disclosed embodiment.
The rotary body 108 comprises a cut-out interrupting its circular profile.
The device 101 comprises a locking element consisting of a locking rod 112 slidingly engaged in a tangential seat or recess formed in the plate 102.
Said rod 112 comprises a cut-out 114 allowing the rotary body 108 to turn, as it is arranged at said cut-out, thereby bringing the rod 112 to its open position, as shown in Figure 8.
In its closed position, the rod 112 interferes against the cut-out of the rotary body 108 profile, as clearly shown in Figure 7.
Thus, the shaped pivot pin 106 of the handle is prevented from turning.
Advantageously, the rod 112 comprises a small lug portion 116 facilitating a gripping and handling of said rod.
According to this embodiment, the device 101 comprises a safety element consisting of a locking dowel 130, which prevents any opening movement, that is a sliding of the rod 112.
Said dowel 130 may be unlocked by a dedicated key, associated with the safety device 101.
The device 101 comprises moreover a spring pressing element 150 engaged in a side of the plate 102.

The plate 202 comprises a throughgoing hole allowing the handle contoured pivot pin 206 to pass therethrough.
Said shaped pivot pin 206 usually has a quadrangular cross-section and engages the door-window opening mechanism, in a per se known way.
According to the present invention, the plate 202 of the safety device comprises, at its throughgoing hole, a seat or recess for a rotary body 208, which includes a contoured or shaped hole, corresponding to the pivot pin 206 shape, in this embodiment a quadrangular shape.
The rotary body 208 has a circular configuration and turns, together with the shaped pivot pin 206, in the seat, also of substantially circular configuration, but with an open side, as in the above disclosed embodiment.
More specifically, the rotary body 208 comprises a cut-out 211 interrupting its circular profile.
The safety device 201 comprises moreover a locking element, consisting of a first lever 212 pivoted to the base 202, and a second contoured or shaped lever 240, adapted to latch and lock the first lever 212.
Thus, as the first lever 212 is disengaged from the second lever 240, it will not hinder the rotary movement of the rotary body 208.
In the closed position, the first lever 212 interferes against the cut-out 211 of the rotary body 208 contour, as clearly shown in Figure 9, and accordingly prevents the shaped pin 206 of the handle from rotating.
The second lever 240 advantageously comprises a lug 216 facilitating a gripping and driving of said second lever.
According to this embodiment, the safety device 201 comprises a safety element consisting of a locking dowel 230 preventing said second lever 240 from being opened, that is from turning.

This embodiment comprises moreover a proximity sensor 160 to detect the distance of the two door and window elements, as it conventionally occurs, for example, in the magnetic contacts applied on frames of alarm systems.
Figure 12 schematically shows an embodiment with an electronic drive of the device 101 and in which like reference numbers are applied to like elements of Figures 7 and 9.
This modified embodiment comprises moreover an infrared or IR sensor 170, to detect the distance of the two door and window elements.
It has been found that the invention fully achieves the intended aim and objects.
In fact, the invention has provided a safety device preventing an accidental or unauthorized opening of a door-window, by preventing the rotary movement of the handle.
The safety device according to the present invention has a small size and is "discreet".
In fact, the device is virtually invisible since the plate 2 has a small thickness and is so contoured as to fit the handle bottom configuration.
The disclosed device embodiments may also comprise a safety element consisting of a locking dowel preventing the door-window from being opened without a dedicate key.
Moreover, all the disclosed embodiments may be controlled by a telecontrol device including an electronic system to detect the open and closed conditions, and to signal possible tamperings.
All the disclosed devices may comprise proximity or IR sensors to read a distance between the two door and window components.
The perimetrical elements allow the device to be fitted to all commercial door-window configurations.
The safety device according to the present invention may also comprise electronic elements to be integrated or built-in in existing door-window patterns.
Likewise, it is possible to mechanically apply, in the disclosed embodiments, suitable sensor elements and electronic circuit controlled drives allowing to make the device active and to be interfaced with an electronic apparatus, also by a radio connection, to operate in an autonomous manner or to be interfaced with an alarm central unit, in a case of a tampering.
