Patent ID: 8491363

Claim:
An air flap device for a cooling or/and freezing appliance of kitchen equipment, the device comprising: an air flap which is mounted so that it can pivot about a first axis of rotation between an open position and a closed position, wherein the air flap uncovers an air passage opening for the passage of air in the open position and at least substantially blocks the air passage opening against the passage of air in the closed position; and a motor-driven flap operating mechanism for pivoting the air flap, the flap operating mechanism comprising: a rotary member which is disposed so as to be driven about a second axis of rotation, wherein the rotary member is free to rotate without limits and when circling the second axis of rotation alternately passes through two dead centre positions, in one of which the air flap is in its open position and in the other of which the air flap is in its closed position; and a separate force transmission member, which serves to transmit force between the rotary member and the air flap, is coupled to the rotary member at a point lying eccentrically to the second axis of rotation and is coupled to the air flap at a point lying at a distance from the first axis of rotation wherein the coupling of the force transmission member to the rotary member and/or the air flap is accomplished through a pin-slotted hole pair to provide mobility of play in the direction of a connecting line between the coupling points on the rotary member and air flap side.
