EP2780640B1 - Ventilation flap - Google Patents

Description

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

The WO 2004/063511 A1 discloses a turn / tilt window which is pivoted about a vertical axis y for normal opening and closing and tilted about a lower horizontal axis x for tilting. The tilting is effected by a power and energy store for opening and a flexible pulling device with a cable pull to close the window in the tilting mode. The flexible pulling device used only for closing has a drive housing with an electric motor and a winding spool connected with a cable pull, which are received in a wing groove at the upper edge of the rotating / tilting wing. The cable pulls on a main scissor link. The axis of rotation of the winding spool is oriented transversely to the tilt axis x at the lower edge of the wing.

Other ventilation flaps, which are also referred to as ventilation or rotating blades, are known from practice. You are e.g. above normal windows and have a horizontal arrangement, where they are opened and closed manually using a rotary handle. The ventilation flaps known from practice contain a narrow window element. The ventilation effect is limited.

The US 6,223,469 B1 concerns a revolving door. The DE 30 43 783 A1 deals with a composite window with adjustable sound insulation ventilation.

It is therefore an object of the present invention to show a better ventilation flap and a flap drive.

The invention solves this problem with the features in the main claim.
The claimed ventilation flap offers an optimal ventilation function, whereby a standing installation position and a large opening angle α of 90 ° are advantageous. In this way, a stronger air exchange can be achieved than with a lying arrangement with a tilting function and a correspondingly smaller opening angle.

The claimed ventilation flap offers high operational and functional reliability. Thanks to the damper actuator, it can be operated and controlled remotely, which e.g. manually using a button or by connecting to an SHEV system. A manual wireless remote control, e.g. by radio, infrared or the like is possible. The ventilation flap can also be thermally insulated and, if necessary, be of solid construction, thereby avoiding or at least reducing undesired heat transfer in the closed position.

The claimed damper actuator has particular advantages for the function and operational safety when pivoting the wing. It is smooth-running and low-wear, whereby the large opening angle can be achieved through the design as a push-crank drive or scissor drive and, moreover, favorable opening and closing forces can be achieved by the drive kinematics. If required, the flap drive can be combined with a manual or also driven locking device which additionally locks and holds the sash in the closed position. The flap drive can be accommodated in the wing, what on the one hand means a protected location and on the other hand it is optically inconspicuous. In particular, optically disturbing attachments to the frame or sash of the ventilation flap can be avoided. The damper actuator is easily accessible via a recess with a cover for assembly and maintenance purposes etc. The cover can only cover the assembly opening or alternatively also a larger wing area, in particular the entire wing area.

It is also advantageous to accommodate parts of the output means, in particular the output element and the thrust element, in a covered overhang or fold area between the frame and the wing of the ventilation flap covering the outside. This also ensures protected and optically unobtrusive accommodation. In addition, there are favorable kinematic drive and motion conditions.

The claimed damper actuator can be mounted and accommodated in or on the wing in any suitable manner. The flap drive and its parts are preferably arranged on a common frame and can therefore be easily assembled as a structural unit and at a prepared location. This can also be done by inserting it at the edge of a wing. For this purpose, it is favorable if the structural unit also contains an edge element of the wing and is assembled together with it, the edge element at the same time closing the installation opening on the wing.

The ventilation flap or its flap drive can also be designed to be self-sufficient and have its own energy supply, e.g. B. a photovoltaic module, and have their own energy storage. In particular, the self-sufficient structural unit of a flap drive can have a control and a communication unit in addition to the aforementioned components. This allows one Standardization of the damper actuator or the unit and its quick and easy installation on different types of sash.

The invention also provides attachment options for sashes and frames in wood or plastic construction, the flap drive having a guide for the thrust element, in particular a sliding block, as an additional component which can be retrofitted to a wood or plastic frame. This is particularly advantageous if such frames have no ribs or the same other form elements that can be used as a guide.

Further advantageous refinements of the invention are specified in the subclaims.

The invention relates to a ventilation flap (1) for buildings, in particular for buildings. The invention further relates to a flap drive (13), in particular a structural unit (37) of a flap drive (13).

Figure 1 shows an example and in a schematic plan view the arrangement of the ventilation flap (1) on a wall (4) of a building. The ventilation flap (1) can be arranged on its own. Alternatively, multiple arrangements are possible. Figure 1 shows a variant in a flap arrangement next to a window (5), with a common frame structure possibly being present.

Figure 1 also illustrates the preferred installation position of the ventilation flap (1). This has an elongated and narrow shape and is preferably arranged upright or standing in the installed position. The ventilation flap (1) consists of a pivotable wing (3) and a surrounding frame (2) on which the wing (3) is rotatably mounted via one or more joints (8) or hinges and about a pivot axis (9). In the installation position shown, the pivot axis (9) runs with an essentially upright or vertical orientation.

A ventilation flap (1) can also have a plurality of pivotable wings (3) on a common surrounding frame (2). Figure 28 shows this variant. The wings (3) can be moved individually and independently of one another with their own flap drive (13). The wings (3) can be moved in the same direction or in opposite directions to open and close, depending on the mounting. In a variant, the several blades (3) can also have a common flap drive (13).

Figure 1 and 11 illustrate the edge-side arrangement of the one or more joints (8) on the wing (3) and on its long side. The wing (3) can thus between the in Figure 9 shown closed position and in Figure 10 shown open position can be pivoted back and forth. Figures 9 and 10 show these positions with a view of the narrow side of the ventilation flap (1). Out Figure 10 the opening angle α can be seen, for example 90 ° can be. Figure 7 also shows this opening position according to the associated top view of Figure 4 , The large opening angle α results in a large-area opening (6) in the frame (2), which enables a large-volume passage of the air to be exchanged, the in Figure 1 and 4 to 6 shown upright installation position is particularly advantageous.

The ventilation flap (1) can have a heat-insulating design. For this purpose, in particular the wing (3) can be solid, its body (7) being of great thickness. It can be so large that the frame opening (6) formed by the peripheral frame (2) is largely filled by the heat-insulating body (7) in the closed position. One or more seals (12) prevent undesired heat and air exchange in the closed position. The frame (2) can also be designed to be heat-insulating.

The frame (2) and the wing (3) can consist of several profiles (10, 11) which have webs and hollow chambers, which may be filled with a heat-insulating material. The profiles (10, 11) can consist of plastic, metal, composite materials or other suitable materials. In the exemplary embodiment shown and preferred, they are designed as light metal profiles, in particular as extruded profiles. The profiles (10, 11) can be assembled like a frame. The wing (3) can have cover plates on the top and bottom of the body (7) and thus have essentially closed surfaces.

The wing (3) opens, for example, into the interior of the building, on which inside the wing (3) has a cover plate projecting over the edge of the body (7), which forms a protrusion or fold (29) and a free space there between the outside frame ( 2) and the inside the body (7) of the wing (3) covered. The cover plate of the wing (3) lies in the closed position with seals (12) on the inner edge of the frame (2). Figure 11 shows this arrangement as an example.

The ventilation flap (1) has a flap drive (13), which is preferably arranged recessed in the body (7) of the wing (3). Parts of the flap drive (13) can extend into the edge-side projection or fold (29) and into the free space there. Figure 11 and 13 illustrate this training. The flap actuator (13) is hidden in the closed position and is not visible from the outside.

The flap drive (13) consists of a drive means (19) and an output means (20) which are connected to one another. The drive means (19) is recessed in the body (7) and is arranged in an interior or cavity (16) of the body (7), in particular a cavity of a profile (11). The cover plate of the body (7), for example on the inside, can have a recess (17) with a removable cover (18) in this area, which enables external access to the drive means (19) for assembly and service purposes. Figure 2, 3 . 5 and 12 illustrate this training. The output means (20) can also be at least partially recessed in the body (7) and is led out of the body (7) at least at one end and protrudes into the aforementioned free space on the fold (29), being outside the body (7) attacks on the frame (2).

In the variant of Figure 11 the body (7) is formed by an elongated profile (11) provided with a plurality of hollow chambers and webs, which is closed on the narrow end faces by panels, end profiles or the like. The output means (20) is through an opening in such an aperture or an end profile led through to the outside. The cavity (16) formed in the profile (11) can have prepared positioning and fastening means for the drive means (19).

In another variant, the body (7) can be formed by a plurality of profiles (11) arranged all around and connected to one another to form a frame, the rectangular profile frame, for example, surrounding a larger interior cavity (16) in the body (7). The flap drive (13) is arranged in this interior or cavity (16). He can e.g. be arranged and fastened on the inside of a longitudinal profile (11). The profile frame can have a lid on the top and bottom to form a closed body (7). One of these covers can be designed to be detachable in order to allow access to the cavity (16) and to the flap drive (13). The output means (20) is guided to the outside through a suitable opening in the profile frame.

The flap drive (13) has a rotating drive means (19) which is designed, for example, as a controllable and possibly regulable electric motor. Any control device can be present for this. The drive means (19) can have an associated control unit (32) which is shown in Figure 18 is shown as an example. It consists, for example, of a control board arranged in the drive housing or next to it. The control board (32) is programmable, and its settings can be changed by wire or wirelessly by means of a computer or parameterization device. With the programming, the opening or closing angle can be set and changed if necessary. Likewise, a start and close function, which is preferably designed as a soft function with a soft starting and braking phase, can be set.

How Figure 1 . 3 and 12 To clarify, the ventilation flap (1) can also have a locking device (14) which can also be operated manually or, as in the preferred embodiment, by means of a drive (36). Said control unit (32) or control board can also control the locking device (14) or its drive (36) via a suitable connection. With the locking device (14) the wing (3) is locked in the closed position relative to the frame (2). For this one or more suitable and, for example, in Figures 4 and 5 indicated locking elements (30) on the wing (3) are actuated and moved, which interact with corresponding counter-elements on the frame (2). This can be, for example, a roller or pin lock with push rod actuation.

In the embodiment shown and preferred, the output means (20) is designed as a crank drive, in particular as a push crank or as a scissor drive. The flap actuator (13) can, for example, have a drive means (19) arranged centrally or decentrally in the longitudinal direction, to which an output means (20) is assigned on one or both sides. The output means (20) also performs a rotary movement and, for this purpose, has, for example, a drive rod or drive shaft (22) which is driven by the drive means (19) and is likewise recessed in the body (7) and is supported by one or more bearings (28) and which carries at one or both free ends an output element (23) which is designed, for example, as a rotationally fixed crank arm or lever arm. Figure 3 and 4 show the preferred arrangement on both sides with a continuous drive shaft and output elements (23) on both narrow sides of the ventilation flap (1).

The axis of rotation (21) of the drive means (19) and the output means (20), in particular the drive shaft (22), is aligned and arranged parallel and at a distance from the pivot axis (9). Figure 5 and 10 illustrate this arrangement. The axis of rotation (21) runs inside the body (7) and is in the closed position in the free space or fold area (29). The output element (23) is also arranged here.

How Figures 7 and 8 clarify, the rotating output element (23), for example the crank or lever arm, is coupled to a thrust element (24) which is guided on a guide (25) on the frame (2) in a suitable movement path. The thrust element (24) is designed, for example, as a sliding block and can be rotated in a suitable manner, for example via a joint (27), with the output element (23). The guide (25) is designed, for example, as a linear guide which extends along a frame side, in particular the narrow side of the frame (2), and which is arranged on the inside of the frame. The linear guide (25) can be form-fitting and is designed, for example, as an undercut link guide. Figure 8 illustrates this training on average. The sliding block (24) overlaps, for example, a central web (26) aligned along the guide (25) and slides along it, with projections on the edge of the sliding block (24) being guided in a form-fitting manner in grooves on the edge of the undercut guide channel.

The flap drive (13) brings about an opening and closing movement of the leaf (3) by means of a reversing rotary movement of the drive means (19) and a corresponding entrainment of the driven means (23) which is non-rotatably coupled to the drive shaft (22). The thrust element (24) is pushed back and forth along the linear guide (25) by means of the rotary movement and an opening or closing movement of the leaf (3) is brought about. This changes the triangular relationship between the swivel axes (9.21) and the joint (27). In the closed position of Figure 9 there is an approximate stretched position and an obtuse angle between the output element (23) and the connecting line of the axes (9.21). In the open position according to Figure 7 and 10 there is an acute angle. The drive torque is supported on the guide (25).

The guide (25) is preferably located on the edge area of the frame (2) near the wing and fold and is oriented transversely to the axes (9, 21). The joint (27) is located approximately at the same height as the pivot axis (9). The drive and rotation axis (21) is preferably arranged at a short distance below the adjacent surface or cover plate of the wing (3).

How Figure 4 . 8th and 13 clarify, the output element (23) and the thrust element (24) can move in the space covered by the fold (29) between the body (7) and the adjacent frame (2). In the case of a preferably standing or upright installation position, the sash weight is taken up on the hinges or joints (8) and the flap drive (13), in particular its one or more output elements (23), is relieved of this.

An actuation (15) is provided for operating the flap drive (13) and possibly the locking device (14). This can be an in Figure 1 indicated switch or button on the wall (4), which is, for example, formed in several parts or movable in different directions and via which the direction of action and direction of rotation of the drive element (19) is switched or controlled and, if appropriate, also the rotation path, ie the opening angle and desired opening or closing position, can be set or controlled. The wing (3) can between a closed position and a maximum open position can be moved back and forth. If necessary, he can also take intermediate positions for a limited opening (6). The opening angle or closing angle can be queried, for example, on the drive means (19), for example via a pulse generator, on the motor. Alternatively or additionally, another measuring system can be present.

The flap actuator (13) can also be operated or operated remotely, e.g. Via a communication device (42) on the control board (32) with connection by wire or wirelessly to a smoke and heat exhaust ventilation system control (SHEV control) with sensors that, if necessary, e.g. If fire or smoke development, heat build-up or the like is detected, the ventilation flap (1) automatically opens and closes again. Via a control coupling and sequence control, the one in the closed position can be actuated automatically and deactivated again to open the ventilation flap (1).

The communication device (42) can also provide information about the ventilation flap (1) and / or the flap drive (13) and / or the locking device (14), e.g. via operating states, faults, position or opening angle of the ventilation flap (1) or the like to an external control unit, e.g. report the RWA control mentioned, a building control system or the like. This information or data can be obtained via the aforementioned measuring system.

Figure 14 to 17 show a variant of the ventilation flap (1), in which the body (7) of the wing (3) is formed by a peripheral frame made of profiles (11) which laterally enclose a central interior or cavity (16). On the top and bottom of this frame lid (18) can be arranged, which in Figure 16 are shown schematically.

The flap drive (13) with the drive means (19) and the driven means (20) can be arranged and mounted on a frame or support (33). A locking device (14) can optionally also be arranged and fastened to the frame or support (33). With the frame or support (33), the components of the flap drive (13) and possibly the locking device (14) can be inserted and installed together in an installation opening (35) on a body side, in particular on a narrow end face.

An edge element (34) of the body (7) or wing (3) can also be arranged on the frame (33). The frame (33) can alternatively also be designed as an edge element (34). The edge element (34) can be, for example, a body profile (11) or a section thereof and / or another fitting part. The edge element (34) can in particular be a profile section of a sash or carcass frame. Said body profile section can be designed as a hollow profile made of metal, plastic or a composite material and can also have a front panel. With the frame (33) or the edge element (34) in the assembly position according to Figures 16 and 17 the installation opening (35) is closed and a connection to the other parts of the body (7), in particular to the other profiles (11), is established. Prepared interfaces can be available for the connection. The edge element (34) can extend over the entire width of the body and can be mitred at the ends for connection purposes. Alternatively, it can be butted against other frame profiles (11). It can also have the above-mentioned overhang or fold (29).

The components of the flap drive (13) provided for mounting in the cavity (16) and the frame (33) or the edge element (34) can form a structural unit (37). A such unit is in Figure 18 to 22 shown. The assembly (37) is provided and designed for the aforementioned insertion into the installation opening (35). It can also accommodate the locking device (14).

In Figure 14 to 17 there is a single arrangement of the installation opening (35) and the structural unit (37) on the wing (3) or on its body (7). Alternatively, there can be a multiple arrangement, in particular a double arrangement, on the upper and lower end faces, in particular the narrow side, of the body (7).

The locking device (14) can have the drive (36) described above, in addition to an associated frame or carrier, and also one or more control elements (30). The locking elements (30) can step out through a side wall of the body (7), in particular a profile (11), and engage with counter-elements on the frame two. Alternatively, you can grip and actuate other locking elements located on the outside of the body and guided there. One or more locking elements can according to Figure 18 also be arranged on the edge element (34).

In the Figure 18 to 22 The unit (37) shown preferably has a particularly compact design. The drive means (19) can in turn be designed as an electric motor, in particular a controllable or possibly also a controllable direct current motor. The drive means (19) can optionally also have a gear (31) connected upstream of the motor, which in turn is connected to the output means (20), in particular its drive rod or drive shaft (22). The axis of rotation (21) of the drive means (19) and the drive rod (22) can be aligned with one another, as can also be the case in the other exemplary embodiments described above. In the compact unit (37), the drive means (19) connected on one side to an output means (20). When installed in the installation opening (35) close to the edge, the drive rod or drive shaft (22) has a smaller length than in the above-described exemplary embodiments with a central drive arrangement.

The frame (33) or edge element (34) extends transversely to the longitudinal and rotational axis (21) of the input and output means (19, 20), in particular the drive rod (22). The drive rod or drive shaft (22) can be supported by a bearing (28) on the frame (33) or on the edge element (34). It penetrates the edge element (34) and comes out with its free end on the edge element (34). Figure 18 and 21 show this arrangement, the bearing (28) is not shown in detail for the sake of clarity.

The control unit (32), in particular in the form of a control board, can be located at a suitable point on the structural unit (37), e.g. be arranged and mounted at the upper end of the drive means (19). The control unit (32) can also act on the locking device (14). It can also accommodate the aforementioned communication device (42).

In the unit (37) from Figure 18 to 22 For example, an output element (23), in particular the crank arm or lever described above, can be arranged on the free end of the drive rod (22) projecting outwards on the body (7). If the output means (20) is designed as a crank drive or push crank, a push element (24) and a guide (25) are also provided, which can be arranged on the frame (2) in the manner described above. One or more of these parts (23, 24, 25) of the output element (23) can be part of the structural unit (37) in the delivery state or can be retrofitted.

In a variant not shown, the structural unit (37) can be of less compact design and can have a drive means (19) designed as a central drive. The drive means (19) can be similar to the previously described embodiments of Figure 1 to 13 be formed and have an electric motor and gearboxes (31) and connecting rods (22) connected in alignment on its two end faces. Possibly. there may also be a single gear (31) and a continuous drive rod which penetrates the electric motor. In this variant, the structural unit (37) can also have a second frame (33) or edge element (34) together with storage (28) for the other, opposite body side. The drive means (19) can be arranged and mounted centrally in the body (7) or in the vicinity of the body edge penetrated by the drive rod (22) if the frame is designed accordingly. In a further variant, not shown, a frame or support (33) can be designed as a mounting plate and can be mounted on the inside of the body (7) or its surrounding frame, with a suitable interface formation possibly being present.

Figure 23 to 25 show a variant of the ventilation flap (1), in which the frame (2) and in particular the wing (3) consist of a wood material. The body (7) can in turn be designed as a hollow box construction with an internal cavity or interior (16) in which a flap drive (13), in particular a drive means (19) and parts of an output means (20) from a flap drive (13), and if necessary, a locking device (14) are also arranged. The arrangement can, for example, according to Figure 26 a central arrangement as in the first embodiments of Figure 1 to 13 his. Alternatively, an end arrangement on an installation opening (35) according to the other embodiment of FIG Figure 14 to 17 possible. The Lateral body walls can be formed by a peripheral frame made of wooden profiles, on the top and bottom of which covers (18) are fixed or detachable. The body (7) can also have a projection (29) as in the other exemplary embodiments.

The frame (2) can have a correspondingly prepared receiving area (38) for accommodating the guide (25). Figure 26 and the corresponding section of Figure 27 show this arrangement. The receiving area (38) can be designed as a step-shaped and partially undercut recess on the edge area of a frame profile (10). A guide rail (25) with a thrust element (24) can be arranged in this receiving area (38).

The drive means (19) with the gears (31) adjoining one or both sides can be mounted in a suitable location and in a suitable manner on a body profile (11) with fittings or the like in the cavity (16). The drive rods or drive shafts (22) extending to one or both sides can have bearings (28) at the end with a fitting for mounting on a body profile (11) which has a through opening for the passage of the drive rod or drive shaft (22).

Figure 28 shows in the aforementioned manner a multiple arrangement, here z. B. a double arrangement of wings (3) on a common frame (2). Each wing (3) has z. B. the shown compact unit (37) according to the above-described embodiments of Figures 14 to 22 , Alternatively, a central drive arrangement according to the first exemplary embodiment of FIG Figure 1 to 13 to be available. In a modification of the embodiment shown, more than two wings (3) can also be present.

Figure 29 shows a self-sufficient variant of a wing (3) or a self-sufficient design of a flap drive (13) and possibly also a locking device (14). For self-sufficient training, there may be a separate power supply (39) for the flap drive (13) and possibly also for the locking device (14) carried on the movable wing (3). Such an energy supply (39) can be a suitable means of absorbing energy, e.g. B. have a panel (40) for absorbing external energy. This can be a photovoltaic for the generation of solar power. Other energy producers are also possible. For local energy storage, the energy supply (39) can be an energy store (41), preferably arranged on the wing (3), e.g. B. have an electric battery. This can be accommodated in the interior (16) of the body (7). The energy store (41) is connected to the flap drive (13) and possibly to the locking device (14). The energy supply (39) can be controlled via the control unit (32).

The wing (3), in particular its body (7), can be made opaque or translucent. He can e.g. have opaque or transparent covers (18) or panes of glass or plastic at least in places. The flap drive (13) in the cavity (16) can be arranged so as to be visible or hidden or can be provided with a covering.

The flap drive (13) and / or the locking device (14) can have an emergency release or a release device for faults, which is accessible or actuatable from the outside.

Modifications of the shown and described embodiment are possible in different ways. The storage (8) or the pivot axis (9) can be different Place, for example in the middle wing area. They can also be constructed in a different way, in particular as a concealed corner bearing with scissors fitting, for example according to the DE 20 2007 017 519 U1 or the DE 10 2010 028 602 A1 , The pivot axis (9) can perform a lateral offset movement in such a corner bearing.

A locking device (14) can optionally be dispensed with. In another variant, the locking device (14) can have a drive derived from the flap drive (13), in particular from the drive means (19), instead of its own drive (36). The locking device (14) can also have locking element (e) with a corner deflection.

The design and / or the arrangement of the drive and driven means (19, 20) can also vary. A crank mechanism can e.g. be designed as a toggle lever drive or in another way. The kinematics of the crank mechanism can be modified, the rotation of the drive rod (22) on the body (7) being converted into a linear movement of a thrust element with which a rotating part mounted on the frame (2), e.g. Crank or lever.

The output means (20) can also have a differently designed output element (23). The rotation at the end of the drive rod (22) can be converted, for example with a gear, into a rotary or linear movement of another, for example rod-shaped or spindle-shaped output element (23) which is kinematically coupled to the frame (2) in another way. In a concealed corner bearing with scissors fitting, the flap drive (13) can engage and move the scissor fitting with a suitable output element (23). Here, for example, a scissor arm, in particular a wing-side scissor arm, driven and moved with the wing (3). An attack is possible, for example, via a threaded spindle, a toothed rack, a cam, a rotating cable drive or the like on a sliding bolt of the scissor fitting in the area of the sash or carcass frame, the linear displacement of which leads to a sash rotation. Alternatively, an attack can take place on a bearing pin, which is connected in a rotationally fixed manner to the other frame-side scissor arm.

The features of the described exemplary embodiments and the modifications can be combined with one another as desired and also exchanged.
