Description

An air vent with an operating device is described which enables air to be deflected and air volume to be regulated with a single operating element.

background

Air vents are used to divert air that has been emitted, which is made available by an air conditioning system or other ventilation device. Air vents are used in vehicles to bring fresh air, temperature-controlled air and / or conditioned air into the passenger compartment of a vehicle. Vehicles can be, for example, motor vehicles, such as cars, trucks or buses, trains, airplanes or ships. In the case of air vents, in addition to controlling the deflection of discharged air, for example from an air conditioning system, the amount of discharged air can usually also be regulated.

The control of the air volume and air deflection can be regulated via an operating device which has an operating element. Depending on the displacement and position of the control element, the amount of air and the deflection of the supplied air are then regulated.

Air vents can be arranged, for example, in a vehicle dashboard or in the area of the A, B or C pillar or on the roof of a motor vehicle.

For air deflection, slats can be provided which are pivotably mounted in a housing. The amount of air supplied can be regulated via a throttle device with at least one closing flap. For this purpose, the at least one closing flap can be pivotably mounted in an air duct. Depending on the position of the closing flap, air is supplied or the air supply is cut off.

State of the art

So-called one-button controls are known which have an operating element which is mounted on a pivotable slat.

Such a control element can be rotated together with the slat, wherein a displacement of the control element causes a pivoting of second slats, which are rotatable about axes running orthogonally to the slat with the control element. In addition, further control elements can be provided which allow adjustment of a throttle device for regulating the amount of air. Further operating elements can be, for example, operating wheels which are arranged next to an air outlet opening.

Out EP 1 207 062 A2 an air outlet for ventilation systems in vehicles with regulating devices for the outlet direction and volume flow is known, the regulating devices having a uniform operating element which changes the outlet direction by translational displacement and the volume flow by rotating around its axis. The operating element is connected by a cardan shaft to an actuating gear that converts the rotary movement of the cardan shaft into an adjustment movement of an air flap.

However, the known designs of control elements for air vents have disadvantages. On the one hand, two different adjustment devices are often required, as a result of which the costs and the assembly effort are increased and, furthermore, the space required for the adjustment devices is very large.

At the off EP 1 207 062 A2 known one-button operation, the design is expanded to the effect that a rotation of the operating element orthogonally to the pivot axis of the air guide lamella is also possible, along which the operating element can be moved. With regard to air vents that have a low height and in which no adjustable slats should be visible in the field of vision, such a control element is not to be used because it requires a rotatable air deflector in the field of vision, ie in the air outlet area.

In the case of joint air outlets, the problem often arises that, although air is deflected via the air guide elements that extend over the width of the air outlet, the effect of the air deflection via the rear lamellae upstream in the direction of flow is lost.

task

The object is to provide an air vent with improved operation. In addition, an alternative solution to the prior art is to be provided. In particular, the possibility of adjusting the air outlet direction and air volume regulation for air outlets with a small outflow height or width, so-called joint outlets, should be provided with a single control element, with no movable air deflectors being arranged in an air outlet opening in the viewing area on the front.

The above-mentioned object is achieved by an air vent with an operating device, at least having a housing with an air inlet opening and an air outlet opening, an air duct being defined between the air inlet opening and the air outlet opening, a fixed air guide element extending over the air outlet opening, a lamella arrangement to the side Air deflection with at least one lamella which is mounted pivotably about a pivot axis extending orthogonally to the direction of extent of the air guiding element, a throttle device for air volume regulation with at least one pivotably mounted closing flap and an operating element which is arranged on the air guiding element, wherein

• - The control element is mounted on the air guiding element so as to be displaceable in the direction of extent of the air guiding element for lateral deflection of air via the lamella arrangement
• - The operating element is mounted rotatably about a first axis (e.g. X-axis) running orthogonally to a plane defined by the air outlet opening for air volume regulation via the throttle device,
• - The operating element is mounted pivotably about a second axis running in the direction of extent of the air guiding element and is coupled to a first transmission unit,
• the first transmission unit is coupled to a first air guide flap and a second air guide flap for additional air deflection in such a way that either the first air guide flap or the second air guide flap can be pivoted by pivoting the operating element about the second axis, and
• - The first air guide flap and the second air guide flap are pivotably mounted on the housing in the air duct.

The air vent enables air volume regulation and air deflection with only one operating element, the operating element being arranged on a stationary, immovable air guide element. As a result, the operating device can be used for air vents and especially for joint vents that have no movable air guide elements in the field of vision. In the case of joint outlets, the air deflection over the wide outflow side in a section of the air duct facing away from the air outlet opening in the area of the air inlet opening is advantageous compared to air deflection in the area of the air outlet opening because the air deflection via the lamellar arrangement downstream in the air flow direction is not negatively influenced while maintaining the air deflection via the air guide flaps . The air vent thus advantageously has an improved air deflection and an improved operating device. The air deflection flaps for air deflection across the "width" of the air vent takes place in terms of flow technology before the "lateral" air deflection via the lamella arrangement. In the case of the air vent, the air guide flaps have a greater extent along their axes of rotation than lamellae of the lamella arrangement.

The operating element can be formed, for example, by an operating button. The control button can be connected to a guide element that can be displaced and rotated along the second axis. The rotation and shifting are carried out via the control button or the control element. The guide element is received in the stationary air guide element. The air guiding element has such an opening on the front visible side in the area of the air outlet opening of the air vent, so that the operating element can be displaced in the predetermined manner to move the guide element and thus to change the air deflection. The remaining area of the fixed air guide element can be designed structurally and optically in such a way that, for example, the impression of a seamless transition between trim parts and the air vent is created. Thus the fixed air guiding element can itself be part of a surface covering, e.g. a vehicle dashboard.

The guide element is coupled to the at least one lamella of the lamella arrangement, so that a displacement along the second axis leads to a pivoting of the lamellae of the lamella arrangement. The guide element is also coupled to the first air guide flap and the second air guide flap, so that a rotation of the guide element in a first direction results in a corresponding rotation and air deflection via the first air guide flap and a rotation of the guide element in a second direction results in a corresponding rotation and air deflection via the second Air damper causes.

The operating element can additionally be mounted rotatably about the first axis in a receptacle of the guide element. A rotation of the operating element causes a change in the inflowing and thus the outflowing amount of air due to the coupling with the throttle device.

The coupling with the adjustable slats, air guide flaps and the throttle device has no effect on the air flow due to the special arrangement, so that the connection and control elements do not lead to an undesirable, additional air deflection and turbulence is avoided. In particular, the Coupling of the air guide flaps with the operating element takes place via the guide element arranged in the fixed air guide element and outside the air duct.

The guide element can furthermore have a fork for coupling to the lamella arrangement, which fork engages around the at least one lamella of the lamella arrangement but is covered by the stationary air guiding element. For this purpose, the fixed air guide element can have a slot or the like on the rear side, facing the air inlet opening, in which the fork and / or a coupling element of the at least one lamella are received. However, the fork can also encompass a coupling pin of the at least one lamella within the stationary air guiding element. The fork encompasses, for example, a section of the coupling link (e.g. coupling pin) of the at least one lamella and thus rotates the lamella about its pivot axis when it is displaced. So that such an adjustment can take place in all positions of the guide element, the fork and the corresponding section can be displaced relative to one another without the fork lifting the grip around the section.

In further embodiments, the first air guide flap and the second air guide flap can be mounted about pivot axes running parallel to the second axis. The air guide flaps can be designed like lamellae. The formation of such lamellae differs through the formation of lamellae of the lamella arrangement in that the air guide flaps have a larger area and the pivot or rotation axes run on or in the housing. This means that air flowing through the housing through the air guide flaps can be deflected "up" and "down" or to the side via the air guide flaps. In the neutral position without actuation, the air guide flaps can, for example, be received in corresponding receptacles in the housing. The housing then has essentially planar inner walls, since the air guide flaps do not protrude into the air duct.

In further embodiments, the first air guide flap and the second air guide flap can be mounted pivotably on their edges facing the air inlet opening. In the pivoted position of the air guide flaps, they protrude from the housing in the air duct, with the free edges protruding in the direction of the air outlet opening. This further improves the deflection of air via the air guide flaps, because the air guide flaps serve as ramps for incoming air.

In further embodiments, the first air guide flap and the second air guide flap can have at least one gear segment in the area of the pivot axis. In this case, gears can be provided which have at least one gear segment. Here, gear segments can be formed by a gear for an upper lamella and a gearwheel for a lower lamella. The gear segments can be arranged at the ends of bearing journals or bearing shafts. The air guide flaps are rotatably mounted in the housing via the bearing journals or bearing shafts. Sections of the bearing journals or bearing shafts protrude from the housing outside the air duct. The gear segments are arranged on these sections. The gearwheel segments of the air guide flaps required for coupling to the first transmission unit are thus arranged outside the housing and do not influence the air flow through the air duct.

In further embodiments, the first transmission unit can have a lever arrangement which transmits the pivoting movement of the operating element about the second axis to a rotatably mounted steering wheel, the steering wheel having a gear section which, depending on the deflection of the operating element about the second axis, either with the gear segment of the first air guide flap or the gear segment of the second air guide flap can be brought into engagement. The steering wheel can be designed as a gear. The lever arrangement can comprise a deflection rod, a lever and a coupling rod. The deflection rod can be coupled or connected to a guide element which, for example, has a toothed segment for coupling to the deflection rod. The guide element can be mounted pivotably about the second axis and can have a pivot axis for this purpose. It is also possible in further embodiments that the guide element is connected directly or indirectly to a lever or a deflection rod of the lever arrangement, so that the rotation of the operating element and thus of the guide element is transmitted to the lever arrangement and thus to the control wheel for pivoting the air guide flaps .

Instead of gearwheel segments, the first air guide flap and the second air guide flap can each be connected to a lever in the area of their pivot axes, which have a guide link.

In a further embodiment, the first transmission unit can have a lever arrangement which transmits the pivoting movement of the operating element about the second axis to a control wheel rotatably mounted about an axis of rotation running parallel to the pivot axes of the air guide flaps. The steering wheel has two pins, one pin in the guide slot of the lever of the first air guide flap and another pin in the guide slot of the lever of the second Air guide flap for rotating the first air guide flap or the second air guide flap is added. The arrangement allows a rotation or pivoting of either the first air guide flap or the second air guide flap without the other air guide flap being moved along with it. For this purpose, the guide slots are designed in such a way that turning the steering wheel in a first direction causes a first pin to rest against a wall delimiting the corresponding guide slot and thus causes the associated air guide flap to rotate. The further, second pin can be guided out of the guide slot, which means that the other air guide flap does not rotate because the pin does not hit a delimiting wall. The guide links are therefore designed in such a way that only one rotation of an air guide flap occurs depending on the direction of rotation of the steering wheel.

In further embodiments, the operating element can be coupled to the throttle device via a second transmission unit. The second transmission unit is used to transmit the rotation of the operating element about the first axis to the throttle device. For this purpose, the operating element can be rotatably mounted in a guide element, as already described above, and coupled to the second transmission unit. Regardless of the design of the second transmission unit, in such an embodiment the operating element can itself be rotated about the second axis independently of the rotation of the guide element and is coupled to the second transmission unit.

In further embodiments, the second transmission unit can have a cardan shaft which is secured against rotation with the operating element, e.g. the control button and a gear is coupled. The cardan shaft is used to compensate for deflections of the operating element relative to the second axis.

In further embodiments, the gear can be in engagement with a gear section of the at least one closing flap. The throttle device can also have two closing flaps, each of which is mounted rotatably about an axis running parallel to the second axis in a rear section of the air duct in the area of the air inlet opening. The closing flaps can each block half of the air duct and can be rotated about the first axis in accordance with the rotation of the operating element. This is done, for example, by the gear on the cardan shaft and gear segments on the closing flaps, which are located in the area of the axis of rotation. In a neutral position, the closing flaps lie parallel to and against each other, whereby the air duct is divided into an "upper" and a "lower" air duct or lateral air duct sections. The division does not have a disruptive effect on the air flowing through, since the fixed air guide element is in continuation of the parallel closing flaps in the neutral position. In a deflected position, the closing flaps can be “spread open” so that, on the one hand, the amount of air supplied is throttled and, on the other hand, the air is directed to the opposite housing walls of the air duct on which the air guide flaps are rotatably mounted. This has the advantage that the air deflection via the air guide flaps is supported when the air flow is throttled.

In further embodiments, the pivot axis of the at least one lamella of the lamella arrangement can run through the stationary air guide element. For this purpose, the fixed air guiding element can, for example, have rear receptacles facing the air inlet opening for the pivot axes of the slats of the slat arrangement. The slats have a recess in this area and surround the rear section of the stationary air guiding element. The louvres are rotated by coupling them to the control element within the fixed air guide element. The slats of the slat arrangement can be coupled to one another for synchronous pivoting via a driver which serves as a coupling rod for coupling the slats, for example inside the stationary air guide element or outside the air duct and outside the housing. From the outside, therefore, neither the coupling between the slats nor the coupling with the control element is visible.

For this purpose, the stationary air guide element is designed to be hollow in further designs, with at least some of the components required for air deflection and air volume regulation being accommodated in the air guide element.

In further versions, parts of the housing and / or the air guiding element can be illuminated in order to realize a definable visual staging and / or to provide feedback on, for example, the temperature of the outflowing air ("red" for warm air / "blue" for cold air) admit.

Detailed description of exemplary embodiments

First embodiment

In the 1-8 is an air vent 100 a first embodiment with an operating device 200 shown. The structure and function of the air vent are described below 100 and operating device 200 of the first embodiment with reference to the 1-8 described.

1 shows a perspective view of an air vent 100 with an operating device 200 for regulating the air deflection and for regulating the amount of air in the first embodiment. The air vent 100 has a housing 110 on. The housing has opposite side walls 112 and 114 on. The side walls 112 and 114 can be connected to each other via connecting elements to form the housing 110 be connected. The side walls 112 and 114 surround the air duct between an air inlet opening 120 and an air outlet opening 130 . The air vent 100 is connected to an air conditioning system of a motor vehicle for supplying conditioned air via ducts (not shown further).

The air vent 100 is arranged so that the air outlet opening 130 at the location of an opening in a diaphragm 600 is located. The aperture 600 can for example represent the surface of a vehicle dashboard. The air vent 100 serves to supply air to the vehicle interior, for example in the area of the driver or front passenger or in the area of the center console. In further embodiments, the air vent 100 can also be arranged in the area of the rear seats or in the roof space.

The case 110 and the components of the air vent described below 100 consist essentially of plastic and are therefore inexpensive and quick to produce in large numbers in an injection molding process.

The air vent 100 has a fixed air guide element 140 on that extends across the width of the air outlet opening 130 extends. The air vent 100 is designed as a joint vent and for this purpose has a small height compared to its width. The air control element 140 extends over the entire width and is fixed to the side walls 114 connected. In further embodiments, not shown, the fixed air guide element 140 be designed as a continuation of a decorative strip of a dashboard, so that the visual appearance of the air vent 100 is adapted to the shape of the dashboard. In the embodiment shown is a Control element 210 an operating device 200 provided that a decorative part 212 has which the control element designed as a control knob 210 surrounds and sideways to the control element 210 extends. The decor part 212 has protruding clips that extend along the stationary air guide element 140 extend.

The control element 210 can be used together with the decor part 212 along the longitudinal axis of the fixed air guide element 140 in Y-direction in 1 are shifted left and right, causing the lamellas to rotate 400 leads around the Z-axis of a lamella arrangement. The control element is for this purpose 210 with a slat 400 coupled via an arrangement still described below. The relocation of the slats 400 is by moving the control element 210 including the decor part 212 visible. The relocation of the control element 210 and the decor part 212 give feedback about the rotation of the slats 400 and thus the direction of the air deflection via the slats 400 .

The slats 400 have journals that come out of the housing 110 emerge. The upper bearing pins protrude through corresponding openings in the side wall 112 out and have a cross section with a profile. For example, the cross section can be cruciform or star-shaped. There are levers on the journals designed in this way 430 placed, which have a corresponding cross section. Away from the axis of rotation of the slats 400 point the levers 430 Coupling pin on, which is in openings of a coupling rod 440 are included. This results in a synchronous pivoting of all slats 400 reached.

The air vent 100 also has air deflectors 300 on, which are stored in the air duct and in 1 are not shown. These can be accessed via an in 1 partially shown transmission unit of the operating device 200 be pivoted alternately. This creates an air deflection orthogonal to the air deflection via the lamellas 400 provided.

The air guide flaps 300 have journals that come out of the housing 110 stick out. The bearing journals of the air guide flaps 300 are with gear segments 310 non-rotatably connected. The control element 210 stands over a lever arrangement with a coupling rod 250 with a steering wheel 260 in connection, which is parallel to the axis of rotation of the air guide flaps 300 around a corresponding axis on the side wall 114 is rotatably mounted. The steering wheel 260 has gear sections 264 on. Depending on the deflection of the steering wheel 260 comes one of the gear sections 264 in engagement with the gear segments 310 the air guide flaps 300 so that there is a corresponding pivoting of one of the air guide flaps 300 comes. The pivoting of the air guide flaps 300 takes place by pivoting the control element accordingly 210 up or down, using a lever 240 the coupling rod 250 is relocated in a corresponding manner. The coupling rod 250 has at their ends bearing openings in which pins 262 and 242 (please refer 6th ) are included. The pencil 262 is with the steering wheel 260 connected.

In addition, the air vent 100 a throttle device 500 on that also via the control element 210 can be actuated and in relation to 8th is explained in more detail. To operate the throttle device 500 can the control element 210 by one orthogonal to one through the air outlet opening 130 The first axis running in the defined plane can be rotated in the X direction.

2 shows a schematic sectional view through the air vent 100 the first embodiment. In 2 is the design of the operating device 200 and the storage of the control element 210 shown. The control element 210 is on the fixed air guide element 140 both along the air guide element 140 displaceable as well as around a bearing shaft 270 pivotable on the fixed air guide element 140 stored. The control element is for this purpose 210 in one shot 222 a guide element 220 recorded. The guide element 220 can in a corresponding receptacle of the air guide element 140 be moved. The air control element 140 points in a front part 142 a storage in which the bearing shaft 270 is recorded. The bearing shaft 270 retains its position in the various positions of the control element 210 at. For moving the control element 210 together with the decor part 212 for swiveling the slats 400 there is sufficient space between the guide element 220 and the mount for the bearing shaft 270 intended. The bearing shaft 270 runs through corresponding openings in the guide element 220 . The guide element 220 cannot itself be rotated in the first embodiment. For the rotation of the control element 210 this has a bearing ball 214 on that on the bearing shaft 270 is mounted rotatably in two directions around the X-axis and the Y-axis. The control element 210 can around the bearing ball 214 and the bearing shaft 270 are rotated, resulting in a deflection of a connecting section 216 of the control element 210 leads. The connecting section 216 is with an in 8th shown cardan shaft 280 connected.

In addition, the control element can be adjusted to the in 2 dashed, through the control element 210 running X-axis can be rotated. So that this rotation in addition to the rotatable mounting of the Control element 210 around the bearing shaft 270 can be carried out, the corresponding opening is in the bearing ball 214 not only designed as a through hole, but extends around the center of the bearing ball 214 in an angular range that allows for a corresponding pivoting of closing flaps 510 the throttle device 500 is required.

The transmission of the rotation of the control element 210 around the bearing shaft 270 for rotating the air guide flaps 300 is referring to the 5 to 7th explained.

For transmitting the shifting movement of the control element 210 together with the decor part 212 is that in a corresponding receptacle of the air guide element 140 arranged guide element 220 with a fork 224 connected. The fork 224 surrounds a coupling pin 420 a slat 400 . The slat 400 is about the in 1 shown coupling rod 440 and the levers 430 with the other slats 400 connected to the slat arrangement for synchronous pivoting.

The slats 400 wise camp 410 on, which is essentially in the center of the slats 400 extend. Camps 410 are in recesses 146 a rear part 144 of the air control element 140 rotatably mounted. The section of the lamella 400 with the coupling pin 420 extends within the air guide element 140 and is therefore not visible from the outside and also does not protrude into the section of the air duct through which air flows. Therefore it comes from the coupling between the control element 210 and slats 400 does not affect the air flowing through. Also the components of the control unit 200 like the guide element 220 , the fork 224 and the elements for coupling with the air guide flaps 300 do not protrude the flow path of the air, but are either inside the hollow air guide element 140 added or arranged outside the air duct.

3 shows a sectional view through the air vent 100 the first embodiment with slats pivoted in a first direction 400 the lamella arrangement. The control element is for this purpose 210 including the decor part 212 shifted to the left. In the illustration it can be seen that the bearing shaft 270 is not shifted, but only the control element 210 including the guide element 220 .

4th shows a sectional view through the air vent 100 the first embodiment with slats pivoted in a second direction 400 the lamella arrangement. The control element is for this purpose 210 shifted to the right in the opposite direction. The transmission of the sliding movement for pivoting the slats 400 takes place through the coupling pin 420 and the fork 224 .

5 shows a further schematic sectional view through the air vent 100 the first embodiment. In 5 is the coupling of the control element 210 and the guide element 220 with a lever arrangement for transmitting the rotation of the operating element 210 around the bearing shaft 270 on the air guide flaps 300 shown.

The guide element 220 is about a tooth segment 226 with a tooth segment 232 a deflection rod 230 connected, which via a corresponding further arrangement of tooth segment sections with a lever 240 is coupled. Instead of the deflection rod 32 can in further embodiments the guide element 220 directly with a lever 240 or a lever 750 (as in the second embodiment) be coupled.

From the lever 240 extends a pen 242 in a corresponding opening in the coupling rod 250 is recorded. One rotation of the control element 210 around the bearing shaft 270 therefore causes the pen to move 242 and thus a movement of the coupling rod 250 . This transmits the movement via the pin 262 on the steering wheel 260 , the gear sections 264 are shifted, one of which is then in engagement with the corresponding gear segment 310 the air guide flaps 300 comes as already with reference to 1 described.

The 6a) and b) show various representations of a first transmission unit for actuating the air guide flaps 300 of the air vent 100 the first embodiment. The 6a) and b) show a neutral position of the air guide flaps 300 , with no rotation of the louvers 300 is done. 6a) shows the view from the outside of the housing 110 of the air vent 100 and 6b) shows the section through in the reduced representation of the air vent 100 shown level.

The lever is not deflected in the neutral position 240 so that the gear sections 264 not in mesh with the gear segments 310 the air guide flaps 300 stand. The air guide flaps 300 are therefore not deflected and the air guide flaps are in this state 300 in corresponding recordings in the opposite side walls 112 . Air flowing through the air duct is passed through the air guide flaps 300 in the neutral position there is no distraction because it is flush with the surfaces of the air duct. The air guide flaps 300 are around parallel to the bearing shaft 270 running axes on a rear, the Air inlet opening 120 facing section rotatable in the housing 110 stored.

In 6th is also the design of the fixed air guide element 140 shown that from a front part 142 and a rear part 144 consists. The air control element 140 has a cross-section that is favorable in terms of flow, so that the air flowing along it in the neutral position is essentially straight out of the air outlet opening 130 is issued. In the event of an air deflection, as in the 7a) to d ) is shown, the curved design of the surface also provides support for the deflection of air using the Coanda effect over the surface of the air guide element 140 .

In the 7a) to d ) are further different representations of the first transmission unit, the operating device 200 and the air guide flaps 300 of the air vent 100 the first embodiment shown, being over the air guide flaps 300 an air deflection downwards ( 7a) and b)) or upwards ( 7c ) and d)).

As in 7th shown, comes when pivoting the control element 210 one of the gear sections 264 of the steering wheel 260 in engagement with a gear segment 310 one of the two air guide flaps 300 so that depending on the deflection of the control element 210 a corresponding pivoting and thus an air deflection via the air guide flaps 300 he follows. Due to the design of the surface of the air guide element 140 and its cross-section takes place, for example, when the air is deflected in 7b) an air deflection via the air outlet opening 130 downwards, the air flow over the lower air guide flap serving as a ramp 300 is directed upwards and thereby essentially only over the upper portion of the surface of the air guide element 140 flows. Using the Coanda effect, the air follows the curve of the air guide element 140 so that the airflow is deflected downwards.

The in 7d ) position of the control element shown 210 and the air guide flaps 300 an upward deflection of air.

The 8a) and b) show various representations of a second transmission unit for actuating the closing flaps 510 the throttle device 500 of the air vent 100 the first embodiment. The cardan shaft 280 has a pan 282 on which the connection section 216 encompasses. One rotation of the control element 210 around the in 8th The X-axis shown in dashed lines thus causes the cardan shaft to rotate 280 . The cardan shaft 280 is where the pan 282 opposite end with a gear 284 non-rotatably connected. One rotation of the cardan shaft 280 thus leads to a rotation of the gear 184 . The gear 284 stands with gear sections 512 the closing flap 510 in connection as this in 9 for the second embodiment is shown.

8a) shows an inoperative state of the throttle device 500 , with no throttling of the air flowing through. In 8b) the throttle device is located 500 in their locked position. In this position the air supply is in the air vent 100 completely cut off, with the two closing flaps 510 around the common axis via a corresponding rotation of the control element 210 are rotated and the protruding ends on the opposite side walls 112 of the housing 110 issue. According to the rotation of the control element 210 the supply of air flow can also be throttled with the closing flaps 510 corresponding intermediate positions between the 8a) and b) can assume the states shown.

The operating device 200 the first embodiment enables both an air volume regulation via the throttle device 500 as well as air deflection via the slats 400 and the air ducts 300 . In this case, a regulation is provided which provides a deflection of air in two directions running orthogonally to one another without the components required for regulation protruding into the air duct and thus causing undesired turbulence.

Second embodiment

In the 9-11 is a second embodiment of an air vent 100 shown. The air vent 100 the second embodiment is different from the air vent 100 the first embodiment ( 1-8 ) by designing the first transmission unit for pivoting or rotating air guide flaps 300 . In addition, the guide element 220 a different design and storage in the fixed air guide element 140 on. Furthermore, the control element 210 no decor part 212 on.

9 shows a sectional view through the air vent 100 with an operating device 200 for regulating the air deflection and for regulating the amount of air in a second embodiment.

The guide element 220 is rotatable in the air guide element 140 stored. A bearing shaft 270 as for the first embodiment, is therefore not required. In addition, the guide element 220 a recording in which a lever 750 recorded and over which the lever 750 with the Guide element 220 is torsionally connected. The lever 750 protrudes from the housing 110 to the outside and is with a coupling rod 700 connected.

Due to the rotatable mounting of the guide element 220 is the coupling of the control element 210 with the cardan shaft 280 more simply designed, the cardan shaft 280 as in the first embodiment a pan 282 which surrounds a connecting section in the form of a bearing ball of the operating element and is connected to it in a manner secure against rotation, so that the rotation of the operating element is transmitted 210 on the cardan shaft 280 provided.

To the back part 144 of the fixed air control element 140 closes a warehouse 150 on. The warehouse 150 essentially has a central mount and bearing for the cardan shaft 280 and the gear 284 on. The warehouse 150 extends over the width of the air duct in the Y direction between the side walls 114 . The warehouse 150 extends in the X direction between the rear side of the air guiding element 140 in the direction of the air inlet opening 120 .

The two closing flaps 510 the throttle device 500 have gear sections 512 on. These are in mesh with the gear 284 so that one rotation of the gear 284 via the cardan shaft 280 due to a rotation of the control element 210 a corresponding rotation of the closing flaps around the X-axis 510 as described for the first embodiment.

The warehouse 150 can starting from a rear, the air inlet opening 120 facing section to the rear end of the second part 144 of the air guide element 140 , which is also the air inlet opening 120 is facing, have an increasing cross-section, being in extension of the camp 150 a continuous surface over the warehouse 150 and the air guide element 140 provided.

For a rotation of the slats 400 has the guide element 220 , as already described for the first embodiment, a fork 224 on which a coupling pin 420 a slat 400 encompasses. The slats 400 are via a coupling rod 440 for synchronous pivoting outside the housing 110 connected (cf. 1 ). The movement of the control element 210 and the guide element 220 This causes the slats to deflect 400 for air deflection. The amount of air is throttled by rotating the control element 210 . The regulation of the air deflection via the air guide flaps 300 takes place by coupling the control element 210 with the coupling rod 700 and the steering wheel 720 as in the 10 and 11 shown.

10 shows a perspective view of components of the operating device 200 and the air guide flaps 300 of the air vent 100 the second embodiment. 11 shows a schematic view of the operating device 200 the second embodiment. 10 and 11 show only part of the components of the air vent 100 .

The coupling rod 700 points cones 702 and 704 on. The cone 702 is in an opening of the lever 750 recorded. The cone 704 is in a coupling opening 724 of the steering wheel 720 recorded. The steering wheel 720 has two coupling openings 724 up so the steering wheel 720 can be used for various types of installation.

The steering wheel 720 is about the warehouse opening 722 on the side wall 114 of the housing 110 rotatably mounted outside the air duct. The air guide flaps 300 have bearing pins over which the air guide flaps 300 rotatable in the housing 110 are stored and out of the housing 110 stick out. The journals are with bearings 744 of levers 740 torsionally connected. The bearing journals and the bearings can do this 744 have corresponding openings and pegs which have mutually corresponding profiles.

The levers 740 show leadership scenes 742 on. In this leadership backdrop 742 stick out pins 710 who are at the steering wheel 720 are arranged.

It comes now by pivoting the control element 210 to a shift of the coupling rod 700 and thus to a rotation of the steering wheel 720 around the warehouse opening 722 , the two pins are shifted 710 in the appropriate direction. One of the pins presses 710 against a corresponding leadership backdrop 742 delimiting wall and, in the event of a further shift on the wall along the guide link 742 guided, with constant pressure on the lever 740 exerted what is a rotation of the lever 740 around the camp 744 and thus a corresponding deflection of the associated air guide flap 300 causes. The relocation of the other pen 710 does not cause any deflection of the associated air guide flap 300 as the pen 710 from the associated management backdrop 742 is led out without hitting a limiting wall, whereby no pressure on the associated lever 740 exercised and thus no rotation of the lever 740 is caused. Will the steering wheel 720 moved back again and rotated in the opposite direction, there is a deflection of the other air guide flap 300 in the appropriate way.

The air vents described herein 100 with the operating devices 200 solve the problems of known air vents mentioned at the beginning. The operating devices 200 have a simple and thus failure-prone structure. The operating devices 200 are in the air control element 140 or outside the case 110 arranged so that this does not affect the air flow through the air duct.

It becomes a control for air vents 100 with fixed air control elements 140 indicated, which has essentially no components that protrude into the air duct in a disruptive manner. In particular, there is also a coupling of several slats 400 via a driver in the form of a coupling rod 440 possible outside the air duct and also the housing 110 lies. The slats point to this 400 on their journals, which define the pivot axes, outside the housing 110 the coupling elements 430 on. These coupling elements 430 act as levers and are parallel to the pivot axis of the slats 400 with the coupling rod 440 connected. Furthermore, the bearings for the coupling elements 430 and the coupling elements 430 even have profiles (eg in the form of a star) so that a defined assembly can be achieved at different angles. This can be used to “press” the slats 400 adjust when swiveling.

The pivoting of the slats 400 takes place as in the 1 to 11 shown and described for the various embodiments, via a displacement of an operating element designed as an operating button 210 , for example together with a decorative part designed as a decorative panel 212 . The air volume is regulated by turning the control element 210 around the X-axis, causing a pivoting of two closing flaps 510 he follows. Finally, there is an additional air deflection via the air guide flaps 300 in the form of horizontal slats by rotating the control element 210 reached around the X-axis running through the control element. The special design of the first transmission unit allows the air guide elements to be pivoted 300 so that the incoming air flow is directed either into a lower or an upper area. There can be different degrees of deflection depending on the deflection of the air guide flaps 300 can be achieved.
