Detailed Description of the Preferred Embodiments
Referring to Figures 1 to 4, a corner anchor 10 for anchoring to an elevated worksite such as a roof is shown. The corner anchor 10, being part of an anchoring system, has a substantially triangular base 12, a shock absorbing portion 14 and a line mount in the
2018202392 04 Apr 2018 form of a sleeve 16. The triangular base 12 is provided and adapted to facilitate direct or indirect attachment of the anchor 10 to the roof for example.
As best shown in Figures 1 and 2, the shock absorbing portion 14 has one end 18 connected to a first edge 20 of the triangular base 12 and being configured to distort under sudden loading. The shock absorbing portion 14 has three serpentine shaped members 22, 24 & 26. The anchoring system also includes a tether (not shown). The sleeve 16 is designed to receive the safety line to which when in use a worker is tethered. The sleeve 16 which is curved in the present embodiment is connected to another end 28 io of the shock absorbing portion 14.
As best shown in Figures 1 to 3, the anchor 10 has reinforcing means which are in the form of a pair of webs 30 & 32. Each web 30, 32 is defined by three sides, namely the substantially horizontal, substantially vertical and a slanting sides. By way of example, is web 32 extends upwardly from a second edge 34 of the triangular base 12 and is attached to the outermost serpentine shaped member 26 via a first frangible joint 36 (refer to Figure 3) configured to break under sudden loading. The web 32 has a substantially horizontal side 38 which runs substantially the full length of the second edge 34. The other web 30 extends from a third edge 40 of the triangular base 12 and is attached to the other outermost serpentine shaped member 22 via a second frangible joint 42. Each triangular web 32 (for example) has a substantially vertical side 44 having a length which is in close proximity to the shock absorbing portion 14 and the slanting side 46 which extends from the upper end of vertical side 44 towards a vertex 48 which is opposite the first edge 20 of the substantially triangular base 12. The slanting side 46 is curved so as to allow more space for placement of a bolt through the hole 50 provided in the base 12. It should be noted that the webs 30 & 32 as reinforcing means are beneficial in that they prevent unintentional or accidental bending of the anchor 10 in the corner when live loaded.
Referring to Figures 5 and 6, there is provided an intermediate anchor 52 which may be incorporated into the anchoring system describe above, as shown in Figure 7. The intermediate anchor 52 has a base 54, a line mount in the form of a straight elongate
2018202392 04 Apr 2018 sleeve 56 and a shock absorbing portion 58. The shock absorbing portion 58 has a pair of serpentine members 68 & 70 being attached to a central support tongue 78 via two frangible joints 80 & 82, as best shown in Figure 6a.
The base 54 is adapted to facilitate direct or indirect attachment of the anchor 52 to an j elevated or overhead worksite such as a roof 60 (see Figure 7). The sleeve 56 is adapted to receive an intermediate portion of the safety line 62 (see Figure 7). In this embodiment, the shock absorbing portion 58 has one end 64 connected to the base 54 and an opposite end 66 connected to the sleeve 56. The shock absorbing portion 58 has two serpentine shaped members 68 & 70 and a substantially C-shaped curved profile 72 io visible from a side view of the shock absorbing portion 58. The opposite end 66 of the shock absorbing portion 58 is joined to one side 74 of the sleeve 56 from which the shock absorbing portion 58 extends laterally and horizontally. It should be noted that the shock absorbing portion 58 must have a substantially non-linear profile which may take the form of any one of the following: C-shaped curved, S-shaped curved, Z-shaped, W15 shaped. The non-linear profile is so configured as to enable a shuttle (see Figure 7) to orientate to a desired location. The non-linear profile is also so configured as to enable additional shock absorption. It will be appreciated that the anchoring system may also include an end anchor having a shock absorbing portion in an identical or similar configuration.
Turning to Figures 7, 7a, 8 and 8a, the shuttle 76, being part of the anchoring system, is adapted to enable binding of a worker to the safety line 62. The shuttle 76 is designed to be detachably connected to and movable along the safety line 62. As best shown in Figures 7a and 8a, the sleeve 56 is configured and orientated such that when in use, the movable shuttle 76 is capable of going over it unobtstructedly. It will be appreciated that the sleeve is so configured and orientated that it allows the shuttle to go over it regardless of the disposition of the tether to which the work is connected. In other words, the intermediate anchor 52 is capable of accommodating unobstructed movement of the shuttle 76 thereby allowing use of the anchoring system in both overhead and belowwaist dispositions, as shown in Figures 7 and 8.
2018202392 04 Apr 2018
Referring to Figures 9a to 9c, a corner anchor 84 which may be incorporated into the anchoring system described above is shown. The corner anchor 84 is to be applied at or near the corner of a building. The anchor 84 has a base 88 which is adapted to facilitate direct or indirect attachment of the anchor 84 to an elevated worksite. For example, the anchor 84 may be directly affixed to a wall by way of a threaded bolt (not shown) via the hole 86 provided in the base 88. The anchor 84 also has a curved line mount in the form of a sleeve 90 adapted to receive a corner portion of a safety line. The curved sleeve 90 is shaped and configured so as to enable the corner portion of the safety line to go around the exterior of a wall corner. The anchor 84 further includes a shock absorbing portion 92 io having one end 94 connected to the base 88 and an opposite end 96 connected to the curved sleeve 90. The shock absorbing portion 92 has two serpentine shaped members 98 & 100 and a substantially hook-shaped curved profile 102 visible from a side view of the shock absorbing portion 92.
is Turning now to Figures 10a and b, the corner anchor 84 may further include or be associated with a fastening means being in the form of a bracket 104. The bracket 104 has a middle element 106 flanked by two arms 108 & 110 which are disposed perpendicularly to one another. The middle element 106 has an aperture (invisible in Figures 10a and b) which is configured to facilitate attachment of the fastening means 104 to the corner anchor 84. Each of the arms 108 & 110 has orifices 112 adapted to facilitate connection of the bracket 104 to the wall corner, as shown in Figures Ila and b. It will be appreciated that the bracket 104 allows the corner anchor 84 to be affixed to the surface of corner walls 114 & 116 instead of a rooftop. As shown in Figures 10a and b, the curved profile 118 of the shock absorbing portion 92 is configured to progressively distort under sudden loading so as to provide a first level of shock absorption, and the serpentine shaped members 120 & 122 are configured to progressively distort under sudden loading to provide a second level of shock absorption. The shock absorbing portion 92 further includes a support member in the form of a tongue 124 for supporting the serpentine shaped members 120 & 122. As in the other embodiments described above, the corner anchor 84 also has frangible joints 126 & 128 (see Figure 10a) for connecting the two serpentine shaped members 120 & 122 to the tongue 124. The frangible joints 126 & 128
2018202392 04 Apr 2018 are configured to break under sudden loading so as to provide a third level of shock absorption.
Now that preferred embodiments of the present invention have been described in some 5 detail, it will be appreciated by a person skilled in the art that the anchor of the present invention may offer at least the following advantages:
1. it prevents bending of the sides when the anchor is applied at a corner;
2. it enables use of the anchoring system in an overhead configuration; and
3. with the addition of a bracket, it permits installation onto walls in place of a roof top.
The foregoing embodiments are illustrative only of the principles of the invention, and various modifications and changes will readily occur to those skilled in the art. The invention is capable of being practiced and carried out in various ways and in other is embodiments. It is also to be understood that the terminology employed herein is for the purpose of description and should not be regarded as limiting.
