ABSTRACT:
The leg portions of metallic yokes which are substantially bent to U-shape comprise free ends adapted to be anchored in the ground, the said leg portions being substantially arranged one behind the other along the line of slope of a hill flank. Mutually adjacent yoke members of the device are interconnected by means of a wire cable which is preferably attached to the curved bights of the yoke members. Additional connecting means disposed between individual, mutually spaced yoke members form intercepting nets bearing against that side of said leg portions which faces the hill flank, said nets being connected to said yoke members, and serving to intercept falling rocks or snow. An important feature of such devices which is of particular importance where such devices are employed in mountainous terrain, resides in the fact that they can be easily transported and can be anchored in the ground in a simple manner. Another advantage of said devices resides in the fact that they are adapted to be deformed elastically upon being impacted by falling rocks or avalanches so as to dissipate the kinetic energy of such material without themselves being destroyed.
