EP2369253B1 - Ventilating apparatus for rooms - Google Patents

Description

The invention relates to a ventilation device for rooms according to the preamble of claim 1.

Such a ventilation device is already known. From the DE 4422862 A1 a ventilation device has become known, which can be arranged on an edge of a frame of a window or a door, and which can be connected for ventilation via openings with the building interior and a building environment in order to enable a limited air exchange between the interior and the surroundings. For this purpose, the ventilation device forms a box which is fastened to the window frame. The box forms a housing and consists essentially of U-shaped or channel-shaped profile parts, and plate-shaped intermediate pieces. Support walls which run parallel to the end plates attached to the longitudinal ends and which support the cover plate and base plate against one another can be inserted into the cavity formed in this way. An element forming an air duct can be inserted into the space between a support wall and an end plate. The air duct runs essentially along the ventilation device and is lined with sound absorption material. A forced fan can be arranged in the air duct.

The disadvantage here is that the configuration only allows an arrangement on the outer edge of the window or door. The ventilation device is not suitable for an arrangement at the edge of a wing filling.

From the DE 8623856 U1 the design of a ventilation device has become known which has an elongated cuboid housing which is composed of a plurality of longitudinally extruded profiles. An inner and an outer profile have openings for air inlet and outlet. In addition to weather protection, the outer profile is provided with a fastening leg, which allows fastening to a profile spar or a filling. The inner profile has a groove for the purpose of mounting a closure element.

To adapt the ventilation device to different length dimensions, all extruded profiles can be cut to the desired size and closed with end caps. The disadvantage here is that the extruded profiles bend over long lengths, which are difficult to join as a result. In addition, due to the small wall thicknesses, no fastening elements can be anchored to the extruded profiles Connection of the filling element or the frame and the ventilation device improved. As a result, attachment between the frame and the building wall is only possible with smaller dimensions of the window or door, since it cannot be anchored in the masonry through the ventilation device.

One of the DE 8623856 U1 Similar design also follows from the EP 0327187 B1 forth.

Further reference is made to the GB 2345533 A . Glazing in the form of a coupled wing consists of a first ventilation part and a second ventilation part. The first ventilation part contains an outlet chamber on the inside of the room. The second ventilation section contains a weather protection roof. A generally rectangular duct is attached close to the first ventilation part and also engages in the second ventilation part. The outlet chamber can be releasably pushed onto an outlet wall of the first ventilation part with a dust filter. The duct can be of variable width from the first ventilation part to the second ventilation part. An exit of the chamber can be defined by a perforated cylindrical part of the chamber and have an area that is at least twice as large as an entrance to the chamber.

The invention is therefore based on the object of providing a ventilation device which can be installed particularly easily in different variants of windows and doors without further processing between the casement and a filler element and the casement and the masonry or in the casement and / or casement and all disadvantages described above eliminated.

This object is achieved with the means of the characterizing part of claim 1.

The fact that the housing contains at least one housing module with an air duct, a closure drive and at least one mounting element, which can be coupled by means of positive and / or non-positive connections, clearly separates the housing on the one hand and the components containing the air duct of the closure drive and the mounting elements. Nevertheless, the assembly is retained through the positive and / or non-positive connections. The result is a ventilation device that can be adjusted in length, the housing of which accommodates various functional modules. In order to be able to attach the ventilation device, the mounting element is designed as a cuboid, with projections and / or profile grooves of the same type being provided on the upright outer and inner surfaces and on the end faces of the cuboid in accordance with the molded parts. The assembly element and the molded parts thus have the same outer contours.

An advantageous further development provides that the extruded profiles containing the housing on the upright outer side consist of an upper and a lower angled profile part, the upper profile part having an arcuate projection which, in accordance with an arcuate free end of the lower profile part, has an air passage opening forms. It has been shown that the flow resistance can be minimized by the curved design.

It is further provided that the lower angled profile part on the upright outer side has a glass holding profile. This simplifies assembly on the filling. In addition, depending on the type of installation situation, the extruded profiles can be combined with each other so that, for example, the lower angled profile part can also be installed without a glass holding profile.

It is also advantageous if angled profile parts are provided on the upright inner side, since the number of profiles required is reduced.

In order to ensure simple assembly, it is provided that the extruded profiles can be connected to the housing module and the mounting element by a snap / snap connection.

A further ease of assembly results from the fact that the end caps with the extruded profiles can be connected to one another by a positive and / or non-positive connection, preferably screws, at least one end cap receiving and fastening the closure drive.

It is advantageous for cost-effective production if the housing module consists of two trough-shaped molded parts of the same design, which can be assembled mirror-symmetrically to one another.

In order to be able to carry out the coupling with the extruded profiles and / or further functional components, it is provided that the molded parts have projections and / or profile grooves on the respective outer surfaces.

An embodiment is particularly advantageous in which the housing module can be coupled in a form-fitting or non-positive manner to other housing modules of the same type by means of front projections and / or profile grooves.

To simplify the assembly of the housing modules, it is provided that the molded parts have a snap / snap connection on one side, engage in a releasable positive engagement via a protruding snap hook with a complementarily undercut snap recess, and form an enclosed space or a recess for receiving the air duct in the assembled state .

In order to ensure a locking function of the housing module in a simple manner, it is provided that the upright outer and inner sides of the molded parts are double-walled and form a pocket which receives a displaceable locking plate, one of which Air passage opening of the molded parts is congruent with the arcuate air passage opening of the profile parts and an air passage opening of the air duct.

It is further provided that at least one push rod is held in a longitudinally displaceable manner in the gap formed between the displaceable closing plate of the housing module and the extruded profile parts, the push rod having a link guide which is movably coupled to the spigot arranged by a spring force. This configuration is advantageous in several respects, since on the one hand the housing module thereby forms the guide means of the push rod, which reliably controls the closing plates due to the simple coulisse guidance, the spring force application ensuring a low-play interaction.

A further advantageous embodiment results from the fact that the connection of the closure drive causes the air passage opening to be opened and closed simultaneously on the outside and inside of the housing. This creates an air cushion that is sealed off from the inside and outside of the housing module and prevents unwanted heat exchange.

In order to be able to actuate several adjacent housing modules, it is provided that the push rod has a coupling device at the free ends, consisting of a recess and a cutout, for the positive connection of further push rods.

A further development provides that the air duct forms a cuboid that is adapted to the size of the resulting recess in the housing module. The air duct can thus be integrated into the housing module.

In order to achieve the greatest possible sound insulation, it is provided that the air duct consists of sound absorbing inserts which are formed from several layers of rectangular sound-absorbing fillers, for example foam pillows, a perforated plate being arranged between the layers. The arrangement results in a clear sound insulation, so that incoming sound is absorbed at the sound absorbing inserts and part of the sound is reflected at the reverberant perforated metal sheets, which are oscillating between the fillers.

If the perforated plate has a honeycomb structure, the size of the openings can be selected on the basis of the strength that is then improved so that the perforated plate also acts as an insect screen, the perforated plate then also being able to be mounted on the inside of the ventilation device between the cover and the housing, so that additional protection against intrusion and visual protection is created. In addition, the honeycomb structure creates a large free cross section, which has an advantageous effect on the air performance.

In order to simplify the design of the air duct, it is provided that the middle layer of the fillers is formed in two parts and forms at least one air passage opening.

The fact that the horizontally running side walls of the air passage opening are clad by the perforated plate and all side walls are formed by the fillers also contribute to improved sound insulation.

A further development provides that the mounting element and the housing module have the same cross-sectional dimensions and that the mounting element can be coupled to the housing module by positive and / or non-positive connection of the same projections and / or profile grooves.

To fix the ventilation device on the window or door, it is provided that the mounting element has a fastening device on the top side and / or on the bottom side with which the mounting element points in the direction of the frame or sash profile.

A first mounting option provides that the mounting device is a mounting screw when mounting the ventilation device between the casement and a glass pane as a fastening means, which is guided in an upright guide of the cuboid, the guide being formed symmetrically transverse to the mounting direction and by one in the guide fixed mounting bracket is rotatably held.

Alternatively, it can be provided that the mounting bracket has an inclined plane and a spring is arranged opposite the inclined plane, the inclined plane of the mounting bracket being supported by the spring on an oblique plane of the cuboid and when the fastening screw is actuated in the mounting direction the ventilation device automatically moves in the vertical direction and in the horizontal direction to the profile seal of the casement, and wherein the fastening screw enters into a detachable connection with the casement. This attachment is particularly suitable for a so-called fighter assembly, in which two fixed frame bars are provided, between which the ventilation device is to be attached.

It can be provided that when the ventilation device is mounted between the fighter profiles, the fastening device has claws arranged as fastening means on mounting blocks, which are guided in an upright guide of the cuboid and the claws point away from one another to the fighter profiles.

The attachment can be effected in that the mounting brackets on the opposite sides of the claws each have an inclined plane directed into the guide, which cooperate with a trapezoidal mounting slide arranged in the guide in a form-fitting manner and can be moved over inclined planes and when actuating one transversely to the plane of the sash and / or frame arranged and rotatably connected to the mounting slide adjusting screw, moves the trestles in the vertical direction to the sash and / or frame and enter into a releasable connection with the claws.

So that the components can be handled together and cannot be lost, it is provided that an undercut groove on the inclined planes of the mounting slide and a T-shaped projection arranged on the respective inclined planes of the mounting blocks slidably guide the positive connection of the mounting slide to the mounting blocks.

In order to achieve the simplest possible adaptation to the sash or frame, it is provided that a cover is arranged on the inside of the housing, covering the housing and spaced from the housing.

The diaphragm can also serve as an information carrier if the diaphragm has a display device, for example for a sensor for informing the room air, the time or the weather station.

Finally, it can also be provided that the diaphragm is a thin-walled plate which is made of a plastic material, a glass pane or a steel sheet. This results in optically advantageous and inexpensive configurations.

In the perspective view of the ventilation device 1, the housing, which can be designed as a cuboid, is generally designated by 2. The ventilation device 1 is provided for mounting on a window or door consisting of a frame 3 and a casement 4 ( Fig. 11 , 13 ). The sash 4 can have a filling element, for example in the form of a glass pane. The housing 2 contains the extruded profiles 6, 7, 8, 9, 10 and 11.

The extruded profiles 6, 7, 8, 9, 10 and 11 form a box that in the Fig. 11 , 13 is clearly recognizable. The extruded profiles 6, 7, 8 on the upright outer side 17 are an upper 6 and a lower 7, 8 angled profile part. The upper profile part 6 has an arcuate projection 18, the contour of which forms an air passage opening LD at a distance from an arcuate free end 19 of the lower profile part 7, 8. This is curved downwards to prevent the ingress of rain. It has been shown that the flow resistance can be minimized by the curved design.

A glass holding profile 21 is provided on the lower angled profile part 8, which is formed on the one hand by a downward leg 21 'and a leg 5 of the extruded profile 9 which runs parallel thereto. This simplifies the assembly on the filling or the filling on the ventilation device 1.

The extruded profiles 10, 11 arranged on the inside 22 are of identical design and are arranged mirror-symmetrically. This reduces the number of profiles required. The extruded profiles 6, 7, 8, 9, 10 and 11 can be connected to a housing module 13 and a mounting element 16 by snap / snap connections.

From the Fig. 1 it can also be seen that the ventilation device 1 in the exemplary embodiment shown has a plurality of housing modules 13 lying next to one another. In addition, several assembly elements 16 are also provided. So follows in the Fig. 1 on an end cap 12, which receives a closure drive 15 and fastens a first mounting element 16 and a first and second housing module 13, which is followed by a further mounting module 16, which is located next to a third housing module 13.

The in the Fig. 15 The end cap 12 shown in detail is a molded part, preferably made of plastic, and has a flange 12 'and a fastening lug 12 "which springs back from it. The outer contour of the fastening lug 12" is designed in accordance with the outer contour of the housing modules 13, so that extruded profiles 6, 7 also fit onto the end cap 12 , 8, 9, 10 and 11 can be locked. In addition, positive and / or non-positive connections by screws are also provided here. The closure drive 15 is mounted in the end cap 12.

In the Fig. 2 to 5 the structure of the housing modules 13 is shown in detail. Each housing module 13 consists of two identical trough-shaped parts 24 which can be joined together in mirror symmetry. For this purpose, two projecting latching hooks 32 are provided on an end face of the shaped part 24, which can be assigned to two latching recesses 33 of the respective other shaped part.

The latching hooks 32 and the latching recesses 33 form a snap / latching connection 31, which can be released again if necessary.

The molded parts 24 facing one another with their openings lie in the assembled state with their narrow edges one on top of the other and form a flat rectangular hollow cuboid which forms an air passage opening 37 and an air passage opening 37 opposite this by two recessed edge edges. In order to ensure a locking function of the housing module 13 in a simple manner, the upright outside and inside of the molded parts 24 are double-walled and form a pocket 35. The pocket 35 is provided with an open-ended slot 35 'at each end. In the pocket 35 there is accommodated a closure plate 36 which is displaceable therein and which penetrate the elongated hole or holes 35 'with the pin 42.

The pins 42 protrude so far beyond the edge of the elongated holes 35 'into a gap 39 which lies between the displaceable closure plate 36 of the housing module 13 and the extruded profile parts 6, 7, 8, 10, 11 that these are guided in link guides 41 ( Fig. 1 ) engage by push rods 40.

The push rods 40 are longitudinally displaceable and have a Z-shaped link guide 41. The closure plate 36 is acted upon by spring force by the pin 42 being attached to a spring tongue.

Although in the Fig. 1 only the push rods 40 attached to the inside 22 can be seen, an identical arrangement has been made on the opposite outside 17. Accordingly, each housing module 13 has a closure plate 36 on both the outside and inside 17, 22 of the housing 2, which causes the air passage openings 20, 37, 38 to open and close synchronously. In the interior of each housing module 13, this creates an air cushion that is sealed off from the outside and inside, which prevents undesired heat exchange and or condensation.

Um - like in the Fig. 1 shown - to be able to actuate a plurality of adjacent housing modules 13, the push rods 40 are provided at their free ends 43 with coupling devices 44. These each consist of a recess 45 and a cutout 46, whereby a positive connection of further push rods 40 is possible. As from the Fig. 1 and 4th As can be seen, each housing module 13 is assigned two closure plates 36 at each air passage opening 37, which are controlled by two parallel push rods 40. As a result, the distance to be covered by the closure plates 36 in order to close the air passage opening 37 is significantly less. The end cap 12 and the closure drive 15 arranged therein are coupled via special shorter push rods 40.

From the Fig. 3 it can also be seen that the molded parts 24 of the housing module 13 have projections 27, 28 and / or profile grooves 29, 30 on the respective outer surfaces 26. The projections 28 have a dovetail cross section and are dimensionally matched such that they can be inserted into the profile grooves 30. Accordingly, this can be done in the Fig. 3 lower molded part 24 with a molded part 24 of the same orientation - in which the locking hooks 32 are also on the right in the drawing - are coupled. The projections 27 interact with correspondingly arranged projections or grooves of the extruded profiles 6, 7, 8, 9, 10 and 11.

It is particularly advantageous that the housing module 13 can be coupled in a form-fitting and / or non-positive manner by means of the above-described configuration to other housing modules 13 of similar construction.

In addition, the housing modules 13 are constructed to be longitudinally symmetrical, so that they can be installed with virtually no confusion.

The design of the molded parts 24 is designed such that they can be produced from plastic by injection molding. Contributing to this are, inter alia, the staggered strip-like projections 27 and the design and arrangement of the projections 28 and profile grooves 29, 30, which enable demolding parallel to the side walls of the molded part 24. The molded parts 24 achieve a comparatively high stability through this design, which is further increased by the type of coupling with neighboring housing modules 13.

Although, as already described above, the housing modules 13 preferably have a symmetrical arrangement of the air passage opening 37, an offset arrangement of the inner and outer air passage opening 37 can also be provided. It is also possible in a simple manner to connect two adjacent housing modules 13 through openings made on the longitudinal end faces. It is also conceivable within the scope of the invention to provide housing modules 13 of different functions in different sizes, for example in order to integrate heat recovery and / or a forced cooling fan.

Already from the Fig. 5 it can be seen that an air duct 14 is assigned to the cavity of the housing module 13. This consists of a cuboid 100, the size of which is adapted to the resulting recess of the housing module 13. In the illustrated embodiment 5 to 8 the air duct 14 consists of sound absorbing inserts which are formed from several layers of rectangular sound-absorbing fillers 101, for example foam pillows.

In addition is after Fig. 6 to 8 A perforated plate 102 is arranged between the layers of the fillers 101, as a result of which the horizontally extending side walls 105, 106 of the air passage opening 38 are clad by the perforated plate 102 and all the side walls 105, 106, 107 are formed by the fillers 101. The arrangement brings about a clear sound insulation, since incoming sound is absorbed at the sound absorbing inserts and part of the sound is reflected at the reverberant perforated plates 102, which are oscillating between the fillers 101.

The structure of the air duct results from Fig. 8 , which makes it clear that an upper and lower flat rectangular cuboid 101 with two flat shorter cuboids 101 of the same width and two perforated sheets 102 are sandwiched together. The division of the middle layer of the fillers 101 in this way forms the air passage openings 38.

The perforated plate 102 preferably has a honeycomb structure 103 corresponding to that Fig. 9 . The perforated plate 102 can also act as an insect screen, the perforated plate 102 then also being able to be mounted on the inside 22 of the ventilation device 1 between the cover 300 and the housing 2, so that an intrusion protection and a visual protection are additionally created. In addition, the honeycomb structure 103 creates a large free cross section, which has an advantageous effect on the air output.

The arrangement of the air duct 14 is selected such that its air passage opening 38 is aligned with the air passage opening 20, 37 when the air duct is installed. Accordingly, it is provided that the outside air passage opening 37 of the molded parts 24 is congruent with the arcuate air passage opening 20 of the profile parts and an air passage opening 38 of the air duct 14.

The fact that the housing 2 contains at least one housing module 13 with an air duct 14, a closure drive 15 and at least one mounting element 16, which can be coupled to one another by means of positive and / or non-positive connections, clearly separates one of extruded profiles 6, 7, 8, 9 , 10, 11 formed housing 2 on the one hand and the components containing the air duct 14 of the closure drive 15 and the mounting elements 16 on the other. In the design according to the invention, these form a covering and a frame. Nevertheless, the assembly is retained through the positive and / or non-positive connections. The result is a ventilation device 1 which is easily adjustable in length and whose housing accommodates 2 different functional modules.

In order to be able to attach the ventilation device 1 is according to Fig. 10 to 14 A mounting element 16 is provided, which according to a further development is designed as a cuboid 200, with projections 204, 205 and / or of the same type corresponding to the molded parts 24 on the upright outer and inner surfaces 201, 202 and on the end faces 203 of the cuboid 200 Profile grooves 206, 207 are provided. The mounting element 16 and the molded parts 24 thus have the same outer contours.

The mounting element 16 and the housing module 13 detects Fig. 1 also the same cross-sectional dimensions. Furthermore, the mounting element 16 can be coupled to the housing module 13 by positive and / or non-positive connection of the similar projections 27, 28, 204, 205 and / or profile grooves 29, 30, 206, 207.

To fix the ventilation device 1 on the window or door, it is provided that the mounting element 16 on the cover side 208 - with which the mounting element 16 points in the direction of the frame or sash profile 3, 4 - and / or on the bottom side 209 a fastening device 210, 211 having.

In a first installation option, it is provided that the fastening device 211 according to Fig. 11 and Fig. 12 when the ventilation device 1 is mounted between the casement 4 and a glass pane as a fastening means, there is a fastening screw 212 which is guided in an upright guide 213 of the cuboid 200, the guide 213 being formed symmetrically transversely to the mounting direction and by a mounting bracket fixed in the guide 213 214 is held rotatably.

Alternatively, it can additionally be provided that the mounting bracket 214 has an inclined plane 215 and a spring 216 is arranged opposite the inclined plane 215, the inclined plane 215 of the mounting bracket 214 being acted upon by the spring 216 on an inclined plane 215 of the cuboid 200 supports and upon actuation of the fastening screw 212 in the mounting direction, the ventilation device 1 automatically moves in the vertical direction and in the horizontal direction to the profile seal 218 of the casement 4, and the fastening screw 212 enters into a detachable connection with the casement 4. This attachment is particularly suitable for a so-called fighter assembly, in which two fixed frame bars are provided, between which the ventilation device 1 is to be attached.

It can be provided that the fastening device 210 according to Fig. 13 and Fig. 14 when mounting the ventilation device 1 between the fighter profiles as fasteners on mounting brackets 219 arranged claws 220, which are guided in an upright guide 221 of the cuboid 200 and the claws 220 pointing away from each other to the fighter profiles.

The attachment can be effected in that the mounting brackets 219 on the opposite sides of the claws 220 are each directed into the guide 221 Have level 222, which cooperate with a trapezoidal mounting slide 223 arranged in the guide 221 in a form-fitting manner, via sloping planes 224, and upon actuation of an adjusting screw 225 arranged transversely to the plane of the sash or frame 4, 3 and rotatably connected to the mounting slide 223, the mounting brackets 219 moved in the vertical direction to the sash and / or frame 4, 3 and enter into a releasable connection with the claws 220.

So that the components can be handled jointly and captively, it is provided that an undercut groove 226 on the inclined planes 222 of the mounting slide 223 and a T-shaped projection 227 arranged on the respective inclined planes 222 of the mounting brackets 219 slidably guide the positive connection of the mounting slide 223 effected with the mounting brackets 219.

In order to achieve the simplest possible adaptation of the ventilation device 1 to the wing 4 or frame 3, as in FIG Fig. 16 or Fig. 17 It is provided that a cover 300 is arranged on the inside 22 of the housing 2, covering the housing 2 and spaced apart from the housing 2.

The diaphragm 300 can additionally serve as an information carrier if the diaphragm 300 has a display device 301, for example for a measuring value transmitter for informing the room air, the time or the weather station.

Finally, it can also be provided that the screen 300 is a thin-walled plate which is made of a plastic material, a glass pane or a steel sheet. This results in optically advantageous and inexpensive configurations.
