Ventilation device

A ventilation device, comprising:

• a housing including at least two horizontal louvers and at least two vertical louvers that are connected so as to intersect in a nested fashion, and a face frame that is arranged on a flow out side of the housing;
• and
• a regulation device which controls at least one flow out direction,
• wherein the regulation device includes a single actuation element configured to adjust the at least two horizontal louvers and the at least two vertical louvers
• wherein the single actuation element is arranged on a flow out side of the housing,
• wherein the at least two horizontal louvers and the at least two vertical louvers are respectively supported in the housing so that the at least two vertical louvers are pivotable about at least two respective vertical pivot axes and the at least two horizontal louvers are pivotable about at least two respective horizontal pivot axes,
• wherein the ventilation device includes a coupling transmission,
• wherein the coupling transmission actuates a horizontal pushrod directly which engages each vertical louver of the at least two vertical louvers directly on a side near an edge that is oriented against the at least one flow out direction,
• wherein the horizontal pushrod extends parallel to the horizontal pivot axis,
• wherein the coupling transmission is connected with a link arrangement,
• wherein the link arrangement is pivotably linked at each horizontal louver of the at least two horizontal louvers and configured to pivot each horizontal louver of the at least two horizontal louvers,
• wherein the single actuation element is directly connected with the coupling transmission, and
• wherein the single actuation element is integrated into the face frame or arranged outside of the face frame,
• wherein the at least two horizontal louvers and the at least two vertical louvers intersect at intersection points,
• wherein the at least two horizontal louvers and the at least two vertical louvers are free from each other in the intersection points, or
• wherein bearings connecting the at least two horizontal louvers and the at least two vertical louvers are formed in the intersection points so that the at least two horizontal louvers are pivotable about the at least two respective horizontal pivot axes in the bearings and the at least two vertical louvers are pivotable about the at least two respective vertical pivot axes in the bearings,
• wherein the intersection points are formed by groove shaped recesses in the at least two horizontal louvers or in the at least two vertical louvers, and
• wherein an axle section of the at least two vertical louvers or of the at least two horizontal louvers is received in the groove shaped recesses.
