Air vent

Abstract

An air vent ( 10 ), in particular for vehicle ventilation, comprising a frame ( 12 ), a first vane system ( 18 ) mounted for pivoting movement about a first axis in the frame ( 12 ), and a second vane system ( 20 ) mounted for pivoting movement about a second axis in the frame ( 12 ), comprises a common operating element ( 28 ) for pivoting the vane systems ( 18, 20 ), which has a slider ( 26 ) mounted on a vane ( 22 ) of the first vane system ( 18 ), and a connecting element ( 38 ) cardanically coupled to the slider ( 26 ), the connecting element ( 38 ) being coupled to a vane ( 24 ) of the second vane system ( 20 ) by means of a slotted guide, wherein the connecting element ( 38 ) is configured so as to have the shape of a fork and in that the slotted guide is formed by two parallel grooves ( 48 ) realized on either side of the vane ( 24 ) and by two pins ( 44 ) provided on the inner side of the fork ends ( 42 ) of the connecting element ( 38 ).

1 . An air vent ( 10 ), in particular for vehicle ventilation, comprising a frame ( 12 ), a first vane system ( 18 ) mounted for pivoting movement about a first axis in the frame ( 12 ), and a second vane system ( 20 ) mounted for pivoting movement about a second axis in the frame ( 12 ),
 a common operating element ( 28 ) being provided for pivoting the vane systems ( 18 ,  20 ), which has a slider ( 26 ) mounted on a vane ( 22 ) of the first vane system ( 18 ), and a connecting element ( 38 ) cardanically coupled to the slider ( 26 ), the connecting element ( 38 ) being coupled to a vane ( 24 ) of the second vane system ( 20 ) by means of a slotted guide,   wherein the connecting element ( 38 ) is configured so as to have the shape of a fork and in that the slotted guide is formed by two parallel grooves ( 48 ) realized on either side of the vane ( 24 ) and by two pins ( 44 ) provided on the inner side of the fork ends ( 42 ) of the connecting element ( 38 ).   
     
     
         2 . The air vent according to  claim 1 , wherein the connecting element ( 38 ) is provided with two guiding elements ( 46 ) each resting on a side face of the vane. 
     
     
         3 . The air vent according to  claim 2 , wherein the guiding elements ( 46 ) are formed by projections provided on the inner side of the fork. 
     
     
         4 . The air vent according to  claim 3 , wherein the cross-section of the projections is larger than the cross-section of the groove ( 48 ). 
     
     
         5 . The air vent according to  claim 1 , wherein the groove ( 48 ) has a depth varying in the direction of the groove ( 48 ). 
     
     
         6 . The air vent according to  claim 5 , wherein the groove ( 48 ) is configured so as to be convex in the direction of the groove ( 48 ). 
     
     
         7 . The air vent according to  claim 1 , wherein the connecting element ( 38 ) comprises a web ( 43 ) which is arranged between the faces of the fork and rests on a guiding surface ( 50 ) provided on the vane. 
     
     
         8 . The air vent according to  claim 7 , wherein the guiding surface ( 50 ) is the edge of the vane ( 24 ) which faces the operating element ( 28 ). 
     
     
         9 . The air vent according to  claim 2 , wherein the guiding surface ( 50 ) is curved. 
     
     
         10 . The air vent according to  claim 1 , wherein the grooves each extend up to an edge of the vane ( 24 ), in particular to the edge of the vane which faces the operating element ( 28 ). 
     
     
         11 . The air vent according to  claim 1 , wherein the grooves ( 48 ) are configured at least partially in a straight line.
