Kind Code:
A
Abstract:
To provide a guard fence that prevents falling objects from going over and improves the effect of catching falling objects by a protection net.SOLUTION: The upper side of a protection net 20 is mounted with respect to the upper side of a support pole 10 in a non-displaceable manner, one side of a net support rope 30 that is inserted into the lower side of the pole 10 is supported by a brake device 32 mounted on a mountain side anchor 31, the other side of the net support rope 30 is connected to the lower side of the protection net 20, when the tension acting on the net support rope 30 exceeds braking force of the brake device 32, the lower side of the protection net 20 is displaceably mounted to the valley side together with the net support rope 30 while slipping.SELECTED DRAWING: Figure 4
