Description

The invention relates to a ventilation valve having features contained in the restrictive part of an independent claim.

Such ventilation valves, also called ventilation flaps or rotary flaps, are known in the art. They are, for example, above standard windows and occupy a horizontal position, and they open and close by hand with the help of a rotary handle. Well-known ventilation valves contain a narrow window unit. Airing efficiency is limited.

Therefore, an object of the invention is to provide an improved ventilation valve.

The invention solves this problem using the features contained in the independent claim.

The claimed ventilation valve offers an optimal ventilation function, and its vertical mounting position and a large opening angle α of 90 ° are advantageous. In addition, enhanced air exchange is achieved compared to a horizontal position with a tilt function and, accordingly, with a smaller opening angle.

The claimed ventilation valve offers high reliability in operation and reliability of operation. Thanks to the valve drive mechanism, it can be controlled remotely, which, for example, can be done by hand using the control button or by connecting to a flue and heat removal system. It is also possible and manual wireless remote control, for example, by radio, using infrared rays or the like. In addition, the ventilation valve can be thermally insulated and, if necessary, continuous, so that in the closed position you can avoid or at least minimize unwanted heat loss.

The claimed valve actuator has particular benefits for its function and operational reliability when the leaf is turned. It has an easy running and wear-resistant, and thanks to its design as a crank mechanism or a cutting drive, the aforementioned opening angle is achieved and, in addition, optimal opening and closing forces can be achieved thanks to the kinematic drive connections. The valve drive mechanism can, if necessary, be combined with a manual or also drive locking device, which further delays and locks the sash in the closed position. The drive mechanism of the valve can be placed essentially in the sash, which, firstly, means its protected location, and secondly, it is not striking. In particular, striking devices in the frame or valve flap can be avoided. At the same time, for mounting the valve drive mechanism and for maintenance purposes, etc. good access thanks to recess with cover. The cover can cover only the mounting hole or alternatively also a large area of the sash, in particular the entire surface of the sash.

It is also advantageous to place parts of the driven means, in particular the driven element and the pushed element, in a closed protruding part or a bend area between the frame and the outside of the closed valve flap. This also ensures a protected and non-eye-catching arrangement. In addition, the optimal conditions for kinematic actuation and movement are formed.

The claimed valve actuator mechanism can be mounted and placed in any suitable manner in the leaf or on the leaf. Mostly the valve actuator and its elements are located on a common basis with the possibility of simple mounting in the form of a structural unit in a prepared place. It can be inserted into the marginal region of the leaf. Best of all, if the structural unit also contains an edge element for the sash and is mounted with it, and the edge element simultaneously closes the mounting hole on the sash.

The ventilation valve or its actuator can be independent and have their own internal energy supply, for example, a photovoltaic solar energy module, and its own energy storage. In particular, the independent structural unit of the valve drive mechanism along with the above components may have a control device and a communication device. This allows you to standardize the valve actuator or assembly and quickly and easily install it on various types of flaps.

The invention also provides for the possibility of installing it for sashes and frames in construction using wooden and plastic structures, and the valve drive mechanism may have a guide for the pushed element, in particular a slide, as an additional component that can be additionally mounted on a wooden or plastic frame . This is particularly advantageous when such frames do not have sections or similar elements that can be used as a guide.

In the dependent claims are presented and other beneficial forms of carrying out the invention.

The invention relates to a ventilation valve (1) for construction, in particular for a building. The invention also relates to a valve actuator (13), in particular to a structural unit (37) of a valve actuator (13).

In FIG. 1 is a schematic top view of, for example, the location of the valve (1) in the wall (4) of a building. The ventilation valve (1) can be one. Alternatively, several ventilation valves may be arranged. In FIG. 1 shows a variant of placing the ventilation valve near the window (5), and, if necessary, there is a general frame design.

In FIG. 1 shows the mounting position of the valve (1). It has an oblong and narrow shape and is located mainly in a vertical or upright position during installation. The ventilation valve (1) consists of a rotatable leaf (3) and an surrounding frame (2), on which the leaf (3) is mounted in supports with the possibility of rotation around the rotary axis (9) using one or more hinges (8) or joints. In the illustrated mounting position, the rotary axis (9) is directed vertically.

The ventilation valve (1) may also have several pivoting flaps (3) on one common surrounding frame (2). In FIG. 28 just shows such an option. The flaps (3) can move independently and independently of each other - each with the help of its own drive mechanism (13). Sashes (3) can move, depending on the installation, in one direction or in different directions for opening and closing. In one embodiment, several folds (3) may also have a common valve actuator (13).

In FIG. 1 and 11 show the location of one or more hinges (8) on the edge of the sash (3) and on its longitudinal side. Due to this, the sash (3) can be pivoted back and forth between the “closed” position shown in FIG. 9 and the “open” position shown in FIG. 10. FIG. 9 and 10 show these positions with respect to the narrow side of the valve (1). In FIG. 10 shows an opening angle α, which can be, for example, 90 °. In FIG. 7 also shows this open position according to a corresponding top view of FIG. 4. Due to the large opening angle α, a large width of the opening (6) of the frame (2) is obtained, which allows the replaced air to pass in a large volume, the vertical mounting position shown in FIG. 1-4 is particularly beneficial.

The ventilation valve (1) may be insulated. For this, in particular, the sash (3) can be made continuous, and its body (7) has a large thickness. It can be so large that the opening of the frame (6) formed by the surrounding frame (2) is filled to the maximum extent with the heat-insulating body (7) in the closed position. One or more gaskets (12) prevent unwanted heat and air exchange in the closed position. The frame (2) can also be insulated.

The frame (2) and the sash (3) can consist of several profiled parts (10, 11) having cross-members and cavities, which, if necessary, are filled with heat-insulating material. Profiled parts (10, 11) can be made of plastic, metal, composite material or other suitable materials. In the presented and preferred embodiment, they are made in the form of light metal panels, in particular in the form of extruded panels. Profiled parts (10, 11) can be composed in the form of a frame. The shutter (3) may have cover panels on the upper and lower sides of the housing (7) and thereby substantially closed surfaces.

The leaf (3) opens, for example, inside the building, and on this inner side, the leaf (3) has a cover panel protruding above the housing (7) at the edge and forming a protruding part or bend (29) and overlapping the free space there between the external side frame (2) and located on the inside of the casing (7) of the sash (3). The sash cover panel (3) abuts in the closed position with the gaskets (12) against the inner edge of the frame (2). Such an arrangement is shown, for example, in FIG. eleven.

The ventilation valve (1) has a drive mechanism (13), which is preferably recessed in the case (7) of the sash (3). The elements of the mechanism can pass into the edge protruding part or bend (29), as well as into the free space there. Such an embodiment is seen in FIG. 11 and 13. The valve actuator (13) in its closed position is hidden and not visible from the outside.

The valve drive mechanism (13) consists of drive means (19) and driven means (20) interconnected. The drive means (19) is recessed in the housing (7) and located in the inner space or cavity (16) of the housing (7), in particular in the cavity of the profiled part (11). For example, the cover panel of the housing (7) located on the inside can have a recess (17) in this area with a removable cover (18) that allows access from the outside to the drive means (19) for its installation and maintenance. Such an embodiment is shown in FIG. 2, 3, 5 and 12. The driven means (20) can also be partially recessed in the housing (7) and withdrawn at least at one end from the housing (7) and enter the above-mentioned free space on the bend (29) and moreover, it is in contact with the frame (2) outside the housing (7).

In the embodiment of FIG. 11, the housing (7) is an elongated profiled part (11) having several cavities and cross members and closed with narrow end faces with plugs, closing profiles or the like. The driven means (20) is directed outward through an opening in such a plug or closing profile. The cavity (16) made in the profiled part (11) may have prepared means for installing and fixing the drive means (19).

In another embodiment, the housing (7) can be formed by several enveloping shaped parts (11) interconnected in a frame, and, for example, a rectangular shaped frame covers a large internal cavity (16) in the housing (7). The valve drive mechanism (13) is located in this internal space or in this cavity (16). Moreover, it can be located and fastened, for example, on the inner side of the longitudinal profiled part (11). The profiled frame may have a lid on the upper and lower sides to form a closed housing (7). One of these covers can be removable for access to the cavity (16) and to the drive mechanism (13). The driven means (20) is directed outward through a suitable hole in the profiled frame.

The valve mechanism (13) has, in a preferred embodiment, a rotating drive means (19), made, for example, in the form of a controlled and, if necessary, adjustable electric motor. For this, any control devices may be involved. The drive means (19) may have a control device (32) associated with it, shown, for example, in FIG. 18. It consists, for example, of a control board located in or adjacent to the drive box. The control board (32) is programmable, and its settings can be changed electrically or wirelessly using a computer or parameter input unit. Using programming, you can adjust the opening or closing angle and, if necessary, change it. You can also set the start and end functions, formed mainly in the form of a “careful” function with a smooth phase of acceleration and deceleration.

As seen in FIG. 1, 3 and 12, the ventilation valve (1) may also have a locking device (14), manually actuated or, as shown in the preferred embodiment, also by means of a drive mechanism (36). Said control device (32) or control board can also control the locking device (14) or its drive mechanism (36) through a suitable connection. Using the locking device (14), the sash (3) is fixed relative to the frame (2) in the closed position. For this, one or several suitable and presented, for example, in FIG. 4 and 5 of the locking elements (30) on the leaf (3), which interact with the corresponding mating elements on the frame (2). This can be, for example, a roller or spike locking device with the actuation of the push rod.

The driven means (20) is made in the presented and preferred embodiment in the form of a crank mechanism, in particular a crank with a connecting rod gear or in the form of a cutting drive. The valve drive mechanism (13) may have, for example, drive means (19), which is located in the longitudinal direction in the center or not in the center and to which the driven means (20) are connected on one side or on both sides. The driven means (20) also rotates and has, for example, a connecting rod or working shaft (22), driven in rotation from the drive means (19) and also recessed in the housing (7) and supported by one or more bearings (28 ) and having a driven element (23) at one or both free ends, made, for example, in the form of a crank arm or lever arm mounted without the possibility of rotation. In FIG. 3 and 4 show a preferred two-way arrangement with a through drive shaft and driven elements (23) on both narrow sides of the valve (1).

The axis of rotation (2) of the drive means (19) and the driven means (20), in particular the working shaft, preferably runs parallel to the rotary axis (9) and is at a distance from it. Such an arrangement is shown in FIG. 5 and 10. The axis of rotation (21) extends inside the housing (7) and is in the closed position in the free space or in the bend area (29). A driven element (23) is also located here.

As seen in FIG. 7 and 8, a rotating driven member (23), for example, a crank arm or a lever arm, is coupled to a pushed member (24) directed along a guide (25) on the frame (2) along a suitable path of movement. The pushed element (24) is made, for example, in the form of a slider and is suitably connected to the driven element (23) with the possibility of rotation, for example using a hinge (27). The guide (25) is made, for example, in the form of a linear guide that runs along the side of the frame, in particular the narrow side of the frame (2), and is located on the inner side of the frame. The linear guide (25) may have a geometric circuit closure and is made, for example, in the form of a rocker guide with an undercut groove. This embodiment is shown in section in FIG. 8. The slider (24) thus covers, for example, the central cross member (26), oriented along the guide (25), and slides along it, and the protrusions on the slider (24) located on the edge are directed into the grooves on the edge of the channel of the guide with a geometric contour.

Due to the reverse movement of rotation of the drive means (19) and the corresponding capture of a driven element (23), coupled to the working shaft without the possibility of rotation, the valve drive mechanism (13) facilitates the movement of the sash (3) to the open and closed position . With the help of rotational movement, the pushed element (24) moves back and forth along the linear guide (25) and helps the sash (3) to open or close. In this case, the “relations” between the rotary axes (9, 21) and the hinge (27) change. In the closed position according to FIG. 9, an approximately elongated position and an obtuse angle between the driven member (23) and the connecting axis line (9, 21) are maintained. In the open position according to FIG. 7 and 10, the angle is sharp. Torque is supported on the guide (25).

The guide (25) is located mainly in the edge region of the frame (2), close to the sash or bend, and is oriented across the axes (9, 21). The hinge (27) is approximately at the same level as the pivot axis (9). The leading rotary axis (21) is preferably located at a small distance below an adjacent plane or cover panel of the sash (3).

As seen in FIG. 4, 8 and 13, the driven member (23) and the pushed member (24) can move in the space between the body (7) and the adjacent frame (2) covered by the bend region (29). In a preferable standing or vertical mounting position, the weight of the sash is received by hinges or joints (8), and the valve drive mechanism (13), in particular its movable element or several movable elements (23), is unloaded.

An actuator (15) is provided for controlling the valve actuator (13) and, as appropriate, the locking device (14). This may be, as shown, for example, in FIG. 1, a switch or button on the wall (4), which, for example, is divided into several parts or can be moved in different directions and with which you can switch or adjust the direction of the working movement and the direction of rotation of the drive element (19) and, if necessary, install or adjust the course of rotation, i.e. opening angle and, accordingly, the desired position is “open” or “closed”. The leaf (3) can move back and forth between the “closed” position and the “maximum open” position. In certain cases, it can also occupy an intermediate position, i.e. limited open position (6). The opening angle or the closing angle can be requested, for example, on the drive means (19), for example using a pulse sensor, on the motor. Alternatively or additionally, another measurement system may be provided.

The valve drive mechanism (13) can be telecontrolled or remotely controlled, for example, using a communication device (42) on a control device (32) with electrical wires or wirelessly to a control device for a flue and heat removal system (RWA control) with a sensor which, if necessary, for example, upon detection of fire or smoke, heat accumulation or the like, automatically opens the ventilation valve (1) and also then closes it again. Thanks to the combination of technical control and servo control system, the ventilation valve (1) can automatically close and re-open.

The communication device (42) can transmit data on the ventilation valve (1) and / or on the valve drive mechanism (13) and / or on the fixing device (14), for example, on the working position, violations, position or opening angle of the valve (1) or the like, to an external control unit, for example, to the already mentioned control device of the flue and heat removal system, a building control device or the like. This information or data may be obtained by the aforementioned measurement system.

In FIG. Figures 14-17 show a variant of the valve (1), in which the case (7) of the sash (3) is formed by an envelope frame of profiled parts that surround the central interior space or cavity (16) from the sides. On the upper and lower sides of this frame, a cover (18), schematically shown in FIG. 16.

The valve drive mechanism (13) with the drive means (19) and the driven means (20) can be installed and mounted on the base or support (33). On the base or support (33), it is possible to position and fix, if necessary, also a locking device (14). Together with the base or support (33), the components of the valve drive mechanism (13) and, if necessary, the locking device (14) can be inserted into the mounting space (35) on the side of the body, in particular on the narrow end side, and mounted there.

On the basis of (33), there may also be an edge element (34) of the housing (7) or the sash (3). Alternatively, the base (33) can also be made in the form of an edge element (34). The edge element (34) can be, for example, a profiled body part (11) or its section and / or other finishing element. The edge element (34) may be, in particular, a profiled portion of the sash or body frame. Mentioned profiled section of the housing may be made in the form of a hollow profile of metal, plastic or composite material and may also have a front plug. Using the base (33) or the edge element (34) during installation, according to FIG. 16 and 17, the mounting space (35) is closed and a connection is created with other elements of the housing (7), in particular with other profiled parts (11). For connection, prepared docking points may be provided. The edge element (34) can extend over the entire width of the housing, and at the ends go to the bevel for connection purposes. Alternatively, it can be joined end-to-end with another profiled part of the frame (11). It may also have the previously protruding portion or bend (29).

The components of the valve actuator (13) provided for installation in the cavity (16) and the base (33) or the edge element (34) can form a structural unit (37). Such a structural unit is shown in FIG. 18-22. The structural unit (37) is provided for the already mentioned introduction into the mounting space (35) and placement there. There you can also enter the locking device (14).

In FIG. 14-17 on the leaf (3) or on its body (7) there is a single arrangement of the mounting space (35) and the structural unit (37). Alternatively, several arrangements can be provided, in particular, a double arrangement - on the upper and lower sides, in particular on the narrow side of the housing (7).

The locking device (14) may have the drive mechanism (36) described above along with its base or support, as well as one or more locking elements (30). The locking elements (30) can protrude outward through the side wall of the housing (7), in particular the profiled part (11), and engage with the mating elements on the frame. Alternatively, they can contact and engage other locking elements located on the outside of the housing. One or more locking elements may be positioned according to FIG. 18, also on the edge element (34).

Presented in FIG. 18-22 structural unit (37) has mainly the most compact design. The drive means (19) can again be made in the form of an electric motor, in particular a controlled or, in certain cases, adjustable DC motor. The drive means (19) may also have, if necessary, also an additional gear (31), which is connected, in turn, with the driven means (20), in particular, with its connecting rod or working shaft (22). The axis of rotation (21) of the drive means (19) and the connecting rod (22) can be located on one straight line, as can also be the case in the other examples described above. With a compact structural unit (37), the drive means (19) is connected on one side to the driven means (20). When installed in the mounting space (35), performed close to the edge, the connecting rod or working shaft (22) is shorter than in the above-described examples with a central arrangement of the drive mechanism.

The base (33) or the edge element (34) extends across the longitudinal axis or axis of rotation (21) of the drive means and the driven means (19, 20), in particular the connecting rod (22). A connecting rod or working shaft (22) can be located in bearings on the base (33) or on the edge element (34) using a bearing (28). A connecting rod or working shaft (22) passes through the edge element (34), and its free end exits on the edge element (34). Such an arrangement is shown in FIG. 18 and 21, and for simplicity, the bearing is not shown in detail.

The control device (32), in particular in the form of a control board, can be located and mounted in a suitable place of the structural unit (37), for example, at the upper end of the drive means (19). The control device (32) may also actuate the locking device (14). In addition, it can receive the communication device mentioned above (42).

In the structural unit (37) of FIG. 18-22, at the free end of the connecting rod (22), protruding outward on the housing (7), is a driven element (23), in particular, the crank arm or the arm arm described above. When the driven means (20) are executed in the form of a crank mechanism or a crank with a connecting rod gear, a pushed element (24) and a guide (25) are provided, which can be positioned on the frame (2) as already described. One or more of these elements (23, 24, 25) of the driven element (23) can be components of the structural unit (37) already upon delivery or can be completed with them later.

In one embodiment not shown here, the structural unit (37) may be made less compact and have drive means (19) made in the form of a central drive mechanism. In this case, the drive means (19) can be performed in the same way as in the already described exemplary embodiments of FIG. 1-13, and have an electric motor, as well as a transmission (31) and connecting rods (22) connected on one straight line from its both end faces. If necessary, one single gear (31) and one connecting rod passing through the electric motor can be provided. In this embodiment, the structural unit (37) may also have a second base (33) or an edge element (34) along with a bearing (28) for the other, opposite side of the housing. The drive means (19) can be positioned and mounted with the corresponding base in the middle of the housing (7) or close to the edge of the housing through which the connecting rod (22) passes. In another embodiment, not shown here, the base or support (33) can be made in the form of a mounting panel and mounted on the inside of the housing (7) or the frame surrounding it, and in certain cases it is possible to provide a suitable execution of the connection points.

In FIG. 23-25, an embodiment of the valve (1) is presented, in which the frame (2) and, in particular, the sash (3) are made of wood material. The housing (7) can again be made in the form of a hollow box-like structure with an internal cavity or internal space (16) in which the valve actuator (13), in particular the actuator means (19) and the elements of the driven means (20) of the actuator ( 13), as well as, if necessary, a fixing device (14). They can be arranged, for example, according to FIG. 26, in the center, as described in the first exemplary embodiments of FIG. 1-13. Alternatively, a terminal arrangement in the mounting space (35) according to another embodiment of FIG. 14-17. The side walls of the housing can be formed by an envelope frame of profiled wood, on the upper and lower sides of which are removable or non-removable covers (18). The housing (7) may have, as in other examples of execution, the protruding part (29).

To accommodate the guide (25), the frame (2) may have a suitably prepared receiving area (38). This arrangement is shown in FIG. 26 and its corresponding section in FIG. 27. The receiving region (38) can be performed on the edge section of the frame profile (10) in the form of a stepped recess with partial undercut. In this receiving region (38), a guide (25) with a pushed member (24) can be arranged.

The drive means (19) with gears connected from one or both sides can be mounted in the cavity (16) in a suitable place and in a suitable way with the help of fasteners or the like on the body profile (11). Cranks or working shafts (22) extending to one or both sides may have a bearing (28) with a lining for mounting on a housing profile (11), which has a through hole for the passage of the connecting rod or working shaft (22).

In FIG. 28 shows the arrangement of several, here, for example, two, shutters (3) on one common frame (2). At the same time, each leaf (3) has, for example, the compact structure shown (37) according to the already described examples of execution of FIG. 14-22. Alternatively, it is possible to provide for the arrangement of the drive mechanism in the center according to the first exemplary embodiments of FIG. 1-13. In contrast to the presented embodiments, more than two flaps can also be provided (3).

In FIG. 29 shows a particular embodiment of the sash (3) or a particular embodiment of the valve actuator (13) and, if necessary, also a locking device (14). For special implementation, it is possible to provide for the valve drive mechanism (13) and, if necessary, also for the fixing device (14), an own electricity supplier (39), in certain cases accumulated on the movable leaf (3). Such an electricity supplier (39) may have suitable means for absorbing energy, for example, a panel (40) for absorbing external energy. It may be a device for converting solar energy into electricity to generate solar electricity. Other energy generators are also possible. For local energy storage, the electricity supplier (39) may have an energy storage device (41) located preferably on the leaf (3), for example a battery. It can be placed in the inner cavity (16) of the housing (7). An energy storage device (41) is connected to a valve drive mechanism (13) and, if necessary, to a fixing device (14). The energy supplier (39) can be controlled using the control device (32).

The leaf (3), in particular its body (7), can be made opaque or opaque. It can have, for example, at least in some places a translucent or transparent cover (18) or a plate of glass or plastic. The actuator mechanism of the valve (13) in the cavity (16) may be visible or hidden or have a lining.

The valve actuator (13) and / or the locking device (14) may have a forced release device or a disconnecting device, accessible or actuated from the outside, in the event of a malfunction.

Various variations of the shown and described embodiment are possible. The bearing (8) or the pivot axis (9) may be located in another place, for example, in the middle region of the sash. In addition, they can have a different design, in particular, can be made in the form of a sheltered corner hinged support with a lining, for example, according to DE 202007017519 U1 or DE 102010028602 A1.

The rotary axis (9) can perform a sideward movement with such an angular articulated support.

The fixing device (14) can in some cases be abandoned. In another embodiment, the locking device (14) may have, instead of its own drive mechanism (36), a mechanism driven by a valve drive mechanism (13), in particular from a drive means (19). The locking device (14) may also have a blocking element (s) with an angular switch.

You can also change the design and / or location of the drive means and the driven means (19, 20). The crank mechanism can be performed, for example, in the form of a knee-lever drive or in another way. The kinematic connections of the crank mechanism may differ, and the rotation of the connecting rod (22) on the housing (7) is converted into the linear movement of the pushed element, by means of which the rotating element, for example, a crank or a lever located on the frame (2), is actuated.

The drive means (20) may also have a slave element (23) made differently. The rotation at the end of the connecting rod (22) can be converted, for example, by transmitting into the rotational or linear motion of another driven element (23), made in the form of a rod or spindle and having other kinematic connections with the frame (2). If there is a sheltered angular hinge support with a lining, the valve actuator (13) engages with a suitable driven element (23) on the lining and moves it. In this case, for example, the lever, in particular located on the side of the sash, can be actuated and move together with the sash (3). It is possible to engage, for example, with a threaded spindle, a gear rack, a cam, a reversing cable drive or the like on the guide pin of the lining in the area of the sash frame or body, the linear movement of which facilitates the rotation of the sash. Alternatively, engagement may occur on a mounting bolt that is rotatably coupled to another arm on the side of the frame.

The valve drive mechanism (13) can be oriented with its rotary and driven axis (21) across the axis of the bearing or the rotary axis (9). It can also be positioned along the profile of the sash or body frame. The same applies to the structural unit (37).

The signs of the described examples of execution and options can be combined with each other, as well as changed.
