Full description Background of the invention

To protect workers working at high altitudes or at risk of falls, lifelines attached to support structures and safety harnesses are used. 5 Examples of lifelines include, but are not limited to, self-retracting lifelines, lanyards, and other suitable lifelines. If a fall event occurs, the rescue ropes reduce the limits of the worker's fall distance.

Another embodiment of the energy absorber group 100` is identical to the energy absorber group 100 except that it includes the anchor assembly 140 for attaching two self-lifting rescue ropes 135 to the joint 101. Whereas the 5 of the energy absorption group 100` is identical to the energy absorber group 100, the main differences will be explained.

As shown at least in Figures 7-9, the anchor assembly 140 includes a first round base 141 designed and arranged to attach to a first self-lifting rescue rope 135 and a second round base 151 designed and arranged to attach to a second self-lifting rescue rope 135.

10 The first round base 141, shown in Figures 17 and 18, has the shape of a ring including a hole 142. The first side 143 for the base 141 includes a projection 144 extending outward near the top, and a second side 145 for the base 141 includes a first swivel joint part 146 extending outward near the top . The first swivel part 146 includes a stator 147, including an elongation boom 147a and a raised flange 147b having a hole 147c. Instead of extending the stator 126 of the set of fixing arms 120 inward as the letter U,

15th The stator 147 extends outward as in a figure 18. The rotor 148 is connected to the flange 147b as is the rotor 127 attached to the flange 126b. The rotor includes 148 holes 149 to attach a self-lifting rescue rope 135 to it, as it is known in the art.

The second round base 151, as in at least Figs 19a and 19b, is a mirror image of the first round base 141. The second round base 151 is annular and has a hole 152.

20 First side 153 of the base 151 includes a second rotor joint part 154 extending outward near the top, and the second side 158 of the base 151 includes a projection 159 that extends outward near the top.

Those are nylon. The base connection 161 includes a cylindrical portion 162 cylindrical portion with a level 163 portion bolted close to one side and a raised flange portion 165 bonded near the other side. The level 163 segment includes a hole 164 near the center of the cylinder segment 162. A track is removed from the cylinder segment 162 from the bottom 166, including an elongation 166a extending outward from the segment 5 level 163. The hole 167 consists of a flange portion 165 flange portion and the bottom 166.

The 141 and 151 round bases are made of alloy steel, held together with the 146 and 154 swivel joints extending out from opposite sides and aligned holes 142 and 152. The base connection 161 is inserted through the holes 142 and 152, bringing the annular parts close to the cylindrical section 162. The anchor bolt 168 extends through the hole 164 and hole 113 to connect the base connection 161 10 to the connection 101. The extension 166a of the base connection 161 is placed under the second girder section 112

for joint 101 to prevent the base joint 161 from axial movement with respect to joint 101. For this, the round bases 141 and 151 are placed between the joint 101 and the flange portion 165. The round bases 141 and 151 rotate independently axially with respect to joint 101 and base joint 161, touching parts Swivel joints 146 and 154 and grooves (shoulder parts) 144 and 159 corresponding grooves 15 114 and 115, which are like stop elements to restrict the swivels of the round bases 141 and 151.

Like the boom assembly 120, the energy absorbing element 170 connects to the clamp arm assembly 140 with one insert from the second end 171b to the first part 171 and the first end 172a to the second part 172 through the holes 142 and 152 from one side of the round bases 141 and 151, the other to the second end 171b of the part The first 171 and the first end 172a for the second part 172 are placed contiguous 20 to the other sides of the round bases 141 and 151, and the ends 171b and 172a are connected, by polarization,

as a second connection 175 to form a second loop around the parts of the ring for bases 141 and 151. The energy absorber element 170 may connect to the mounting arm assembly 140 before inserting the base connection 161 through holes 142 and 152 or after inserting the base connection through holes 142 and 152 and connecting it to connection 101 .

25 In the event of a fall, the retaining bolt 168 is deformed or broken and the base connection 161 separates from the connection 101, freeing the round bases 141 and 151 from the connection, upper part 191 of the cap 190

Detaches from the rear side 201, and sections 171 and 172 of the energy absorbing element 170 detach and come out of the housing 190, which reduces the rate of fall and the amount of forces exerted on the user during a fall. Depending on the fall distance, variable lengths of sections 171 and 172 may be separated.

Figure 9 shows how the 141 and 151 round bases are positioned during the fall. The link is connected 101

5 With user safety harness hardware, the first self-raising rescue rope 135a is attached to the abutment structure. With sections 171 and 172 of the energy absorbing element 170 separated, the second self-lifting lifeline 135b simply slides along the section of the energy absorbing element 170 while continuing to separate sections 171 and 172.
