Definitions

• the invention relates to an air vent with at least one blade and a control element which is mounted in a bearing pivotable and / or rotatable on the blade.
• Air vents in vehicles often have a central control element, on the one hand, the direction of the outflowing air, but also the amount of air of the air vent can be regulated.
• pivoting the control element can be adjusted with the control element coupled horizontal and vertical slats of Lucasausströmers.
• a locking device can be adjusted and thus the amount of air flowing through the air vent can be regulated.
• the control can be pivoted with the slats, the bearing is the control very far set back in the case, for example, on the pivot axes of the slats.
• the swivel angle of the slats is often limited by end stops. Likewise, stops are provided on the closing device, against which the closing device rests in an end position. If, upon reaching these stops, an actuating force is still applied to the operating element, the linkage which couples the operating element to the closing device or the bearing is heavily loaded. The bearing is heavily loaded due to the large lever and can be damaged in extreme cases. Likewise affect the linkage large bending forces.
• Such an air vent is shown for example in DE 100 57 421 A1.
• the object of the invention is to provide an air vent, in which the load on the bearing of the operating element or the mechanics of the operating element is reduced and thus damage to the bearing of the operating element or the mechanism is prevented.
• an air vent with at least one blade, a control element which is mounted in a bearing pivotally and / or rotatably mounted on the blade, and provided with a stabilizer which is movably mounted on the control.
• the stabilizer has stop surfaces, and on the blade and / or on the control element stop surfaces are provided, wherein the abutment surfaces of the stabilizer can move in a movement of the operating element on the contact surfaces in abutment and limit a pivoting and / or rotational movement of the control.
• the invention is based on the consideration, not to limit the range of movement of the slats or the locking device or to limit the range of movement of the control element on the camp, as is done in the prior art, but directly on the control to arrange an additional stabilizer, the radius of movement directly Control element limited.
• the stabilizer thus acts as a stop for the operating element, so that not the pivoting range of the slats or the adjusting range of the closing device, but directly the range of movement of the operating element is limited before a load on the bearing or the adjacent mechanism can act.
• the force exerted on the operating force is therefore not transferred to the bearing or the linkage, but directly via the stabilizer on the lamella or other components of the Lucasausströmers.
• On the bearing and on underlying components, such as a transmission linkage so no or only low-power forces are transferred in the limitation of the pivoting or rotating path of the control, so that they are safely protected from damage.
• the stabilizer is mounted on the control element that the stabilizer or the abutment surfaces of the stabilizer when pivoting or rotating the control element with the contact surfaces come into contact.
• the control element has, for example, a shaft and the stabilizer has a recess through which the shaft extends. Thereby, the stabilizer can be pivoted together with the operating element, wherein a rotational movement of the operating element is still possible.
• the stop surfaces are preferably arranged in the pivoting direction and the contact surfaces provided on the blade. The control element is therefore pivoted so far with the stabilizer until the stabilizer in the pivoting direction, so for example, laterally or upwardly or downwardly abuts the contact surfaces of the blade, whereby further movement of the control element is prevented in the pivoting direction.
• the stabilizer is pivotable, but rotatably mounted on the blade. That is, the stabilizer can be moved during pivoting of the operating element in a pivoting direction against lamella-side stops.
• the stabilizer is prevented from turning with the control element. Since the stabilizer is not rotatable, for example, the orientation of the abutment surfaces to the contact surfaces on the blade does not change, so that it is ensured that they can come into contact with each other when pivoting the operating element.
• a stop surface may be arranged radially to the longitudinal axis of the shaft and the contact surface is arranged on the control element radially to the longitudinal axis.
• the stop surface and the contact surface are arranged so that they can come into contact with each other when turning the operating element.
• a further rotation of the operating element is blocked by the fact that the stabilizer is rotatably mounted on the blade and thus can not rotate with the control. If the contact surface on the operating element comes into contact with the stop surface, a fixed counter bearing is thus formed, as a result of which further rotation of the operating element is reliably prevented.
• the control element can also be constructed in several parts and in particular have a handle element which is attached to the shaft.
• the contact surface is preferably arranged on this grip element. This structure allows easy assembly of the air vent.
• the shaft can for example be installed in a first assembly step and the stabilizer can be plugged onto the shaft. Subsequently, the grip element is mounted with the contact surface on the shaft, wherein the orientation of the Gripping element on the shaft of the rotation range of the operating element can be adjusted.
• At least one sliding surface may be provided on the lamella, against which the stabilizer and / or the operating element rests.
• This sliding surface is for example spherical, wherein the center of the spherical surface is preferably the pivot point of the operating element, that is, the bearing.
• the stabilizer or the operating element are in contact with a guide surface on the sliding surface, so that there is always contact with the sliding surface when the operating element is pivoted. As a result, for example, a depression of the operating element is prevented, since the sliding surface supports the operating element in the longitudinal direction of the shaft.
• sliding surface and stabilizer may additionally be provided a sliding and / or damping element. This can, for example, reduce the friction between the sliding surface and the stabilizer, so that operation of the operating element with lower operating forces is possible. Alternatively, the friction can also be increased, so that the operating element can not be moved from a preset position. Likewise, between the stabilizer and lamella and / or control element sliding and / or damping elements may be provided.

• FIG. 9 shows a detailed view of the linkage from FIG. 8.
• FIGS. 1 a and 1 b a known from the prior art air vent 10 is shown with a so-called one-button operation.
• the air vent 10 has first, horizontally arranged lamellae 12, which can each be pivoted about an axis of rotation 14, and second, vertically arranged lamellae 16, which are also pivotable about an axis of rotation 18.
• a closing device 20 is provided, which has a closing flap 22 which is pivotable about an axis 24.
• a common operating element 26 is provided which is mounted on a horizontal slat 12 and coupled to the vertical slats 16.
• the operating element 26 is mounted with a bearing 30 on the lamella 12. In this bearing 30, the operating element 26 can be rotated in order to adjust the closing flap 22.
• a linkage 28 is provided on the operating element 26, via which the operating element 26 is coupled to the closing device 20.
• the vertical slats 16 can be pivoted about their axes of rotation 18. If the control element 26 is moved vertically, thereby the horizontal Slats 12 pivoted about their axes of rotation 14.
• the closing flap 22 can be adjusted via the linkage 28 and thus the air flow through the air vent 10 can be regulated.
• the operation of such a Heilausströmers 10 is known per se and is therefore not further explained.
• the bearing 30 is designed so that the slats 12, 16 are pivoted together with a movement of the operating element 26 with the operating element 26. For optical reasons, this bearing 30 is set back very far into the housing 32 of the air vent 10. However, this results in a relatively long lever arm h between the grip element 34 of the operating element 26 and the bearing 30 (see FIG. 2).
• the pivoting range of the slats 12, 16 and the closing flap 22 is limited. If the maximum impact of the slats 12, 16 or an end position of the closing flap 22 is reached, they can not be pivoted further in a further application of force to the operating element 26, wherein the operating forces continue to act on the bearing 30 and the linkage 28. This can lead to damage of the bearing 30 or the rod 28.
• the air vent 10 In order to reduce the load on the operating element 26 or the linkage 28, the air vent 10 according to the invention additionally has a stabilizer 36 shown in FIGS. 2 and 3.
• the structure of the remaining Gutausströmers corresponds to the structure of a conventional Heilausströmers, as shown for example in Figures 1 a and 1 b.
• the operating element is, as can be seen in particular in Figures 4 and 5, constructed in two parts, with a shaft 40 and a handle member 34 that is secured with a receptacle 42 on a provided on the shaft 40 torque transmission structure 44.
• the shaft 40 has a spherical thickening 46, with which the shaft 40 in the bearing 30 is mounted pivotably and rotatably.
• the stabilizer 36 has a recess 38 through which a shaft 40 of the control element 26 projects, so that the shaft against the stabilizer 36 is freely rotatable.
• the recess 38 forms a kind of further storage for the shaft 40th
• the stabilizer 36 has a first section 48 which has a substantially rectangular cross section on, with opposite first Anchlag vom 50 and offset by 90 ° arranged second, also opposite abutment surfaces 52.
• annular portion 54 of the stabilizer 36 are radially projecting webs 56 is provided, on each of which a radially arranged to the longitudinal axis radial abutment surface 58 is provided.
• a receiving space 60 is formed, in which the shaft 40 and the first portion 48 of the stabilizer 36 are received.
• the receiving space 60 has a substantially rectangular cross-section. Laterally, ie in the horizontal direction H, the receiving space 60 is bounded by first contact surfaces 62, which are arranged at a height with the stabilizer 36 and the first stop surfaces 50. In the vertical direction V of the receiving space 60 is limited by second abutment surfaces 64.
• the handle member 34 has a cup-shaped recess 66 in which the stabilizer 36 is partially received. In this recess 66 radial bearing surfaces 68 are provided, which, as will be explained below, can cooperate with the radial stop surface 58.
• a sliding surface 70 is provided on the front edge of the lamella 12, against which a guide surface 72 of the operating element 26, which is provided on the grip element 34 in the embodiment shown here, rests (FIGS. 5 to 7).
• the sliding surface 70 is formed substantially in a partial spherical shape, wherein the radius to the pivot point of the operating element 26 in the bearing 30 is constant.
• damping elements 76 are provided at the second stop surfaces 52 of the stabilizer.
• the distance between the second contact surfaces 64 is selected such that the stabilizer 36 abuts against the abutment surfaces 64 with the damping elements 76. In the vertical direction V, the stabilizer thus has no play and can not be pivoted against the blade 12. If the operating element 26 is moved in the vertical direction V, the horizontal slat 12 is pivoted with the operating element 26. The movement of the operating element 26 is thus transmitted via the stabilizer 36 and the abutment surfaces 52 and the damping elements 76 on the blade 12, so that the blade 12 are pivoted together with the control element 26.
• the operating element 26 In order to pivot the vertical slats 16, the operating element 26 is moved in the horizontal direction H.
• the receiving space 60 is formed so that the operating element 26 and the stabilizer 36 have sufficient freedom of movement to pivot the slats 16.
• the contact surfaces 62 thus have a sufficient distance from each other to pivot the operating element 26.
• the operating element 26 can be pivoted in the horizontal direction H until the first stop surfaces 50 rest against the first contact surfaces 62. As soon as the abutment surfaces 50 bear against the bearing surfaces 62, further horizontal pivoting of the operating element 26 is no longer possible.
• the operating element 26 or the grip element 34 is rotated. This movement is limited by the fact that the radial contact surfaces 68, which rotate together with the handle member 34, come to the radial abutment surfaces 58 of the stabilizer 36 in abutment.
• the stabilizer is indeed pivotable in the horizontal direction in the receiving space 60, but rotatably mounted on the blade 12 about the longitudinal axis of the shaft 40. Since the abutment surface 64 bears against the radial abutment surface 52, further rotation of the operating element 26 would only be possible by rotating the stabilizer 36. Thus, further rotation of the operating element 26 is prevented by the stabilizer 36.
• the radial abutment surface 58 and the radial abutment surface 68 are positioned so that this limitation of the rotational movement coincides with the closed position or a fully open position of the closure flap 22. Thus, an overuse of the linkage 28 upon reaching the closed position of the closing flap 22 and a further rotation of the operating element 26 is reliably prevented.
• first abutment surfaces 50 and the first abutment surfaces 62 are positioned so that the operating element 26 is stopped in a horizontal pivoting before a load of the bearing 30 or other components can take place.
• the pivoting range of the operating element 26 is also limited when the maximum pivoting angle of the lamella 12 is reached by the stabilizer 36, which cooperates with the lamella 12 via the first stop surfaces 50 and the first contact surfaces 62.
• the stabilizer 36 which cooperates with the lamella 12 via the first stop surfaces 50 and the first contact surfaces 62.
• the air vent of the prior art which is shown in Figures 1 a and 1 b, so when reaching the maximum deflection of the slats 12, 16 or upon reaching an end stop of the slats 12, 16 or the closing device 20th no further forces acting on the bearing 30 or the rod 28.
• the movement of the control element 26 is blocked directly on the control element 26, so that a further force on the bearing 30 and subsequent components is prevented.
• the damping element 76 here has the function to provide additional friction between the stabilizer 36 and blade 12, so that it is ensured that the operating element 26 remains in a set position due to the higher friction.
• the damping element 76 can eliminate or compensate for any existing game, so that a rattle or unwanted noise of the control element 26 is reliably prevented.
• a further damping element 78 is provided between the stabilizer 36 and the shaft 40 and increases the friction between them, so that even with a rotational movement there is a higher friction, which holds the operating element 26 in a set position.
• the damping elements 76, 78 and sliding elements can be used by which reduces the friction and the sliding properties between the stabilizer 36 and blade 12 and shaft 40 are improved.
• additional length compensation elements 80 may be provided on the linkage 28. These are formed from a cylinder 82, in which a shaft member 84 projects. On the cylinder 82 and the shaft member 84 corresponding torque transmission profiles are provided. In the embodiment shown here, a longitudinal groove 86 is provided on the cylinder 82 and the shaft element 84 has a groove 86 corresponding to the rib-like projection rail 88. The shaft member 84 can be pushed in and out of the cylinder 82 in the longitudinal direction, regardless of the position of the shaft member 84 in the cylinder 82, a rotationally fixed connection through the groove 86 and the projection 88 is formed.
