Definitions
- the present invention generally relates to the construction of windows and doors.
- the invention more particularly relates to a ventilation device and window or door incorporating same, employing techniques for providing ventilation associated with the window or door.
- Fig. 1(a), Fig. 1(b) and Fig. 1(c) PRIOR ART
- such products include trickle vents integrated into the window profile or into the wall adjacent to the window so as to allow ventilation for air renovation with a window closed; and these are usually flaps operated directly by hands ( Figs 1(a) ), rods ( Fig. 1(b) ) or wires ( Fig. 1(c) ) or electronically.
- the operating element is not integrated with the window locking mechanism, and two separate types of operation are required.
- EP2824265A2 discloses a window comprising at least one (rotatably opening) sash and a tiltable top window / skylight above the sash(es).
- a mechanism controlled by a manually operable handle on a sash is configured, through certain movements of the handle, to also open and close the skylight.
- JP H04 102691 A describes a door comprising a shutter having apertures.
- JP 2010 156146 A describes a door operating device.
- JP 2016 023433 A describes a door which draws, opens and closes an arc centring on a hinge.
- EP 0 291 540 A1 describes a window fitting comprising a rotatable handle arranged on a frame side and a sliding push rod arranged at the outer edge of the frame side.
- a problem is that, with known (trickle) ventilation arrangements for windows and doors, there is a need to open and close the ventilation devices with a dedicated closing mechanism separate from that of the window or door, requiring an additional operation to the opening and closing the ventilation device. Moreover, sometimes the ventilation device is not easy to reach as it is installed in an inconvenient place (i.e. on the top of the window), i.e. such that it is difficult to operate and requires long wires or rods in order to do so, thereby often providing limited aesthetics.
- This object is achieved by a ventilation device as claimed in claim 1, and the window or door as claimed in claim 17.

Fig. 1(a), Fig. 1(b) and Fig. 1(c) (PRIOR ART), such products include trickle vents integrated into the window profile or into the wall adjacent to the window so as to allow ventilation for air renovation with a window closed; and these are usually flaps operated directly by hands (Figs 1(a) ), rods (Fig. 1(b) ) or wires (Fig. 1(c) ) or electronically. However, the operating element is not integrated with the window locking mechanism, and two separate types of operation are required. - Further,
EP2824265A2 discloses a window comprising at least one (rotatably opening) sash and a tiltable top window / skylight above the sash(es). A mechanism controlled by a manually operable handle on a sash is configured, through certain movements of the handle, to also open and close the skylight. Similarly,JP H04 102691 A JP 2010 156146 A JP 2016 023433 A EP 0 291 540 A1 describes a window fitting comprising a rotatable handle arranged on a frame side and a sliding push rod arranged at the outer edge of the frame side. - A problem is that, with known (trickle) ventilation arrangements for windows and doors, there is a need to open and close the ventilation devices with a dedicated closing mechanism separate from that of the window or door, requiring an additional operation to the opening and closing the ventilation device. Moreover, sometimes the ventilation device is not easy to reach as it is installed in an inconvenient place (i.e. on the top of the window), i.e. such that it is difficult to operate and requires long wires or rods in order to do so, thereby often providing limited aesthetics. Moreover, when the ventilation is provided by the window sash in tilt position, the acoustic and thermal insulations are very poor compared with a trickle vent, the entrance of insects is not avoided and moreover the window itself is not safely closed thereby allowing the opening by burglars.
- It is an object of the present invention to provide ventilation device and window or door incorporating same, in which the same manually-operable handle used to secure and release the window or door may be used to open and close the ventilation. This object is achieved by a ventilation device as claimed in
claim 1, and the window or door as claimed inclaim 17. - In order to overcome the above-mentioned issue, the present invention provides a ventilation device for a window or door, the ventilation device being configured to be installed at a peripheral mounting surface of a frame, at a mounting surface in said frame or at a mounting surface in a sash of the window or door from which an actuation member projects, the actuation member being connected via a linkage mechanism to a locking mechanism of the window or door.
