a preferred anchorage system constructed according to the principles of the present invention is designated as 100 in fig1 - 2 . generally speaking , the system 100 is connected to a support structure 90 and supports at least one safety line 160 , 161 . among other things , the system 100 is suitable for use as a component in horizontal safety line systems like those disclosed in u . s . pat . no . 5 , 343 , 975 to riches et al . ; u . s . pat . no . 5 , 279 , 385 to riches et al . ; u . s . pat . no . 5 , 224 , 427 to riches et al . ; and u . s . pat . no . 4 , 790 , 410 to sharp et al ., all of which are incorporated herein by reference . as shown in fig2 the system 100 includes a first curved plate 110 having an arcuate profile when viewed from below . the profile is preferably configured to match or conform to the exterior of the support structure , which is depicted as a cylindrical post 90 . each end of the plate 110 is secured to the post 90 by means of a respective fastener designated as 180 ( and including a mating nut and bolt ). each associated bolt extends through a respective hole in the plate 110 and through a respective member 190 , which preferably functions as both a spacer and an energy absorber . the respective holes in the plate 110 are offset vertically relative to one another to avoid interference between the respective bolts in the region of their intersection inside the post 90 . as shown in fig2 a second curved plate 120 has a somewhat u - shaped profile when viewed from below . however , the opposite distal ends of the plate 120 extend in divergent fashion and preferably define an angle equal to the change in direction experienced by the safety line 160 , 161 ( approximately 110 ° on the depicted embodiment 100 ). each distal end of the second plate 120 is secured to a respective end of the first plate 110 by means of a respective fastener 181 ( including a mating nut and bolt ). each associated bolt extends through aligned holes in the plates 110 and 120 , and through a respective member 191 disposed between the plates 110 and 120 . an intermediate segment of the second plate 120 is similarly connected to an intermediate portion of the first plate 110 , with a relatively longer member 192 disposed therebetween , and a relatively longer fastener 182 ( including a mating nut and bolt ) inserted through the member 192 and interconnected between the plates 110 and 120 . like the members 190 , the members 191 and 192 preferably function both as spacers and as energy absorbers . as shown in fig2 a third curved plate 140 has a profile comparable to that of the second plate 120 . each distal end of the third plate 140 is secured to a respective end of the second plate 120 by means of a bowl - shaped bracket 130 disposed therebetween . at each end , fasteners 183 ( including mating nuts and bolts ) are interconnected between the second plate 120 and a rim portion of a respective bracket 130 , and a fastener 184 ( including a mating nut and bolt ) is interconnected between the third plate 140 and a base portion of a respective bracket 130 . each fastener 184 also secures a respective bracket 151 to the plate 140 . the plate 140 is relative taller than the plate 120 , in order to accommodate the second set of brackets 150 , which are secured in place by respective fasteners 185 . however , the present invention is not limited to any particular number of safety lines . the brackets 150 and 151 and the safety lines 160 and 161 are identical to those disclosed in u . s . pat . no . 5 , 343 , 975 to riches et al ., except that the brackets 150 and 151 are relatively more rigid and preferably made of stainless steel . also , the system 100 is constructed so that the members 190 - 192 are the first , and ideally the only , components to deform in response to a fall or any comparable load on either line 160 or 161 . in this regard , the plates 110 , 120 , and 140 are also preferably stainless steel , whereas the members 190 - 192 are comparable to # 40 engine block mounts made by mckay industries in australia . as a result , replacement of the brackets 150 and 151 ( and the associated hassles ) is a less frequent concern . those skilled in the art will recognize that the system 100 may alternatively be constructed with brackets that are designed to deform . in other words , deformable brackets identical to those disclosed in u . s . pat . no . 5 , 343 , 975 to riches et al . may be used in the system 100 to provide an alternative system where the line supporting brackets are the first components to deform . in yet another alternative arrangement , otherwise deformable brackets , like those disclosed in u . s . pat . no . 5 , 343 , 975 to riches et al ., may be modified or reinforced to resist deformation . for example , reinforcing plates may be interconnected between the brackets 150 and 151 and the plate 140 . the plates are preferably configured to match the profile of the brackets 150 and 151 ( including the relatively thin neck portion but not the tubular line supporting portion ). the plates 170 are preferably made of stainless steel and welded to both the brackets 150 or 151 and the plate 140 . with the addition of the plates , the members 190 - 192 would , once again , be the first components of the system to deform . the present invention also provides various methods which may be performed in assembling and / or using the system 100 . this disclosure will enable others to realize various embodiments and / or applications . therefore , although the present invention is described with reference to a preferred embodiment and a particular application , the scope of the present invention should be limited only to the extent of the following claims .
an anchorage assembly is interconnected between a support structure and a safety line . the anchorage assembly routes the safety line about a corner and accommodates passage of a slotted coupling device movably mounted on the safety line .
