|20140196382||SUPPORT POST STRUCTURE - A support post structure includes: a ground plate mounted on a support post anchor driven into the ground or a concrete base; a support post; a universal joint for tiltably supporting a lower end of the post; a lower support plate placed on an upper end of the post; a spring; an upper support plate; a bolt inserted through the lower support plate, the spring, and the upper support plate; a nut threaded into the bolt; and a rope hanging between a mooring part of the bolt and a predetermined position near the lower end of the post. The support post is brought to a standing state when the rope is tightened by the nut and is tiltable in all directions when a guard fence receives a falling rock or the like, autonomously restoring to the initial standing state when the rock is removed.||07-17-2014|
|20120132876||GUARD SURFACE STRUCTURE - There is provided a guard surface structure excellent in shock-absorbing effect due to an unprecedented structure formed by combining a deformable supporting surface and shock-absorbing members. A guard surface structure comprises a net body||05-31-2012|
|20110297907||SHOCK-ABSORBING DEVICE FOR NET BODY OF GUARD FENCE - There is provided a shock-absorbing device for a net body of a guard fence, capable of improving a net body's effectiveness of absorbing impact by enlarging the amount of deformation of the net body once the net body has been subjected to a force of impact due to rockfall, mudslide, avalanche or the like. A net body||12-08-2011|
|20110002743||LOAD BEARING MATERIAL - There is provided a load bearing material with a high energy-absorbing effect at the time of deformation. A metallic external tube||01-06-2011|
