Description

The invention relates to a ventilation flap with the features in the preamble of the main claims.

Such ventilation flaps, which are also referred to as ventilation or rotary wing, are known in practice. You are z. B. above normal windows and have a horizontal arrangement, being opened and closed by hand via a rotary handle. The ventilation flaps known from practice contain a narrow window element. The ventilation effect is limited.

The DE 295 21 220 U1 is concerned with a device for automatic, timed opening and closing of windows and ventilation flaps, wherein the drive of the device is arranged outside the window or the ventilation flap and has a micromotor with a cam disc and a crank hinged thereto.

From the alien DE 103 00 655 A1 is a window or a door with tilt function and with a drive for Schliessen from the open tilt position known, the drive is coupled with a tilting fitting and the outside is arranged on a window frame. The drive has a flexible cable with a winding drum.

From the DE 197 56 496 C2 is known a revolving door drive.

It is therefore an object of the present invention to provide a better ventilation flap.

The invention solves this problem with the features in the main claim.

The claimed ventilation flap provides optimal ventilation function, with a vertical mounting position and a large opening angle α of 90 ° are advantageous. This is a stronger exchange of air than in a horizontal arrangement with tilt function and a correspondingly smaller opening angle achievable.

The claimed ventilation flap offers high operational and functional safety. It can be operated remotely thanks to the damper drive and control what z. B. via a button by hand or by connection to an RWA system is possible. The ventilation flap can also be thermally insulated and, if necessary, formed solid and thereby avoid unwanted heat transfer in the closed position or at least reduce.

The claimed damper actuator has particular advantages for the function and reliability when swinging the wing. It is smooth and low-wear, which can be achieved by training as a sliding crank drive or scissors drive said large opening angle and also favorable opening and closing forces can be achieved by the drive kinematics. If necessary, the damper drive can be combined with a manual or likewise driven locking device, which additionally locks and holds the wing in the closed position. The damper drive can be accommodated essentially in the wing, which means on the one hand a protected position and on the other hand visually inconspicuous. In particular, optically disturbing attachments on the frame or wing of the ventilation flap can be avoided. The damper drive is easily accessible via a recess with lid for mounting and maintenance purposes. Also advantageous is the placement of parts of the output means, in particular the output element and the thrust element in a covered overhang or fold region between the frame and the outside overlapping wing of the ventilation flap. This also ensures a protected and visually unobtrusive accommodation. In addition, favorable kinematic drive and movement conditions result.

In the subclaims further advantageous embodiments of the invention are given.

The wing ( 3 ) can be moved back and forth between a closed position and a maximum open position. He may also provide intermediate positions for a limited opening ( 6 ). The opening angle or closing angle can, for. B. on the drive means ( 19 ), z. B. via a pulse generator to be queried on the engine. Alternatively or additionally, another measuring system may be present. The flap drive ( 13 ) may also be remotely operated or remotely operated, z. B. via line or wireless connection to a smoke-heat exhaust control system (RWA control) with sensors that, if necessary, z. B. in detected fire or smoke, heat accumulation or the like. Automatically the ventilation flap ( 1 ) opens and closes again. Via a tax-technical coupling and sequential control, the locking device ( 14 ) in the closed position automatically and to open the ventilation flap ( 1 ) are deactivated again.

Modifications of the embodiment shown and described are possible in various ways. The location ( 8th ) or the pivot axis ( 9 ) can elsewhere, z. B. in the middle wing area, be arranged. The ventilation flap ( 1 ) can have several wings ( 3 ) in a common frame, which are moved in the same direction or in opposite directions to open or close depending on the storage. Here, a common valve drive ( 13 ) or separate damper actuators ( 13 ) together with corresponding locking devices ( 14 ) to be available. On a locking device ( 14 ) may be waived if necessary. The structural design of the drive and driven means ( 19 . 20 ) may vary. An output medium ( 20 ) can z. B. a toggle lever or a differently designed output element ( 23 ) exhibit.
