DAMPENING DEVICE FOR WIND BREAKER DOORS

A mechanism is needed to be set up as shown in drawing, that the door is open only to inside, in order to function. By opening the door first plate rotate, and under pressure pushes the second plate which closes the main opening of air and thereby attenuates the air flow and thus makes it difficult to suddenly open the door if the wind blows. When closing the door the first plate is rotated to the other side, second plate moves backward, and opens up a greater air flow and thus facilitating the closing of the door. This mechanism is easy to standardize and it can be used on every door. It is small and almost invisible, and development should be very cheap. This is only an approximate idea and need to be elaborated. I think that in the principle it should work.
