Patent ID: 7104733

Claim:
A method to hinder the progress of avalanches that fall with high velocity and contain an enormous amount of energy, characterized by catching the avalanche in a special protection system ( 1 ), which mainly consists of a net sack ( 9 ) fastened by main strings ( 3 , 11 ) to the ground, and an oblong storage box ( 16 ) consisting of a storage platform ( 5 ), that stands on poles ( 4 ) equipped with hinges ( 6 ), and a protection helmet ( 17 ), where the net sack ( 9 ) is ready and waiting inside the storage box ( 16 ), whereas the protection system ( 1 ) is planted on a mountain slope, in a canyon, at the foot of a mountain or at other places where the risk of falling avalanches exists, in such a way that one of the long side of the storage box ( 16 ) faces the direction from which the avalanche falls and the air mass, that the avalanche thrusts ahead of itself as it falls, flings the protection helmet ( 17 ) backwards away from the platform ( 5 ), and whereby the net sack ( 9 ) opens because of the wing units ( 7 ) and the net sack then flings out of the storage box, where the platform ( 5 ) and flat plates ( 8 ) helps to keep the net sack open because of the effect from the air stream, the form of the wings and the other components and their placement above, below and sideways of the opening of the net sack.
