Anchor assembly
View Patent ↗An anchor assembly includes a base to which at least one connector and three legs are operatively connected. The connector provides an anchorage point for connection to a lifeline. The legs are secured to a support structure. The legs are reinforced proximate the base and when a force is exerted on the at least one connector by the lifeline, the legs bend proximate the support structure thus placing a shear load on the legs proximate the support structure.
1. An anchor assembly for connection to a support structure, comprising:
a base having a top and a bottom;
at least one connector connected to the base proximate the top and configured and arranged for connection to a lifeline;
at least three legs each having a first end and a second end, the first ends connected to the base proximate the bottom and being reinforced proximate the base, the second ends being connectable to the support structure, wherein the legs bend proximate the support structure when a load is exerted on the connector thus positioning the connector proximate the support structure and placing a shear load on the at least three legs proximate the support structure;
a reinforcement sleeve for each leg to provide reinforcement for each leg, each reinforcement sleeve having a threaded bore that extends through a length of the reinforcement sleeve;
a mounting member for each leg, each mounting member being coupled proximate the bottom of the base, each mounting member including a threaded receptacle; and
the first end of each leg having threads, the threads of the first end of each leg being threaded through a respective threaded bore of an associated reinforcement sleeve and into a respective threaded receptacle of an associated mounting member to connect the leg to the base.
2. The anchor assembly of claim 1 , further comprising an extension connected to the base and extending upward from the base, wherein the at least one connector is connected to the extension.
3. The anchor assembly of claim 2 , wherein the extension is slidable downward through a bore in the base and the at least three legs are pivotable inward to position the anchor assembly in a storage position.
4. The anchor assembly of claim 1 , wherein each of the at least three legs has a length and each reinforcement sleeve extends downward approximately one fourth to one third the length.
5. The anchor assembly of claim 1 , wherein the reinforcement sleeves have a thicker gauge and a larger diameter than the legs.
6. The anchor assembly of claim 1 , wherein each of the at least three legs includes a swivel bracket proximate the second end to which a foot assembly is connected.
7. The anchor assembly of claim 1 , wherein four legs are connected to the base and each of the four legs includes a swivel bracket proximate the second end, a first rail assembly being connected to a first two adjacent legs and a second rail assembly being connected to a second two adjacent legs.
8. The anchor assembly of claim 1 , wherein the load is at least 200 to 500 pounds.
9. The anchor assembly of claim 1 , wherein the load is up to 5400 pounds.
10. An anchor assembly for connection to a support structure, comprising:
a base having at least three mounting members;
a connector connected to the base, the connector being configured and arranged for connection to a lifeline;
a leg connected to each mounting member, each leg having a first end and a second end, the first end being connected to the base, the second end being connectable to the support structure;
a reinforcement sleeve connected to each leg proximate the base, the reinforcement sleeves having a thicker gauge and a larger diameter than the legs;
the at least three mounting members having threaded receptacles, the reinforcement sleeves having threaded bores, and the legs having threaded top portions, wherein the top portions of the legs are threaded through respective threaded bores of the reinforcement sleeves and into respective threaded receptacles of the mounting members; and
wherein the legs bend proximate the support structure when a load of at least 200 to 500 pounds is exerted on the connector thus positioning the connector proximate the support structure and placing a shear load on the at least three legs proximate the support structure.
11. The anchor assembly of claim 10 , further comprising an extension connected to the base, the connector being connected to the extension, wherein the extension is slidable downward through a bore in the base and the legs are pivotable inward to position the anchor assembly in a storage position.
12. The anchor assembly of claim 10 , wherein each of the legs has a length and each of the reinforcement sleeves extends downward approximately one fourth to one third the length.
13. The anchor assembly of claim 10 , wherein the load is up to 5400 pounds.
14. An anchor assembly for connection to a support structure, comprising:
a base including a bore;
an extension extending through the bore and being slidably connected to the base;
a connector connected to the extension, the connector configured and arranged for connection to a lifeline;
mounting members including threaded receptacles and being pivotally connected to the base;
legs including a first end and a second end, the first end being threaded, the second end configured and arranged for connection to the support structure;
reinforcement sleeves including threaded bores extending longitudinally therethrough; and
wherein the first ends of the legs are threaded through respective threaded bores of the reinforcement sleeves and into respective threaded receptacles of the mounting members, the reinforcement sleeves having a thicker gauge and a larger diameter than the legs, the legs bending proximate the support structure when a load is exerted on the connector thus positioning the connector proximate the support structure and placing a shear load on the legs proximate the support structure.
15. The anchor assembly of claim 14 , wherein the mounting members are at least three mounting members, the legs are at least three legs, and the reinforcement sleeves are at least three reinforcement sleeves.
16. The anchor assembly of claim 14 , wherein the extension is slidable downward through the bore in the base and the legs are pivotable inward to position the anchor assembly in a storage position.
17. The anchor assembly of claim 14 , wherein each of the legs has a length and each of the reinforcement sleeves extends downward approximately one fourth to one third the length.
18. The anchor assembly of claim 14 , wherein the load is 200 to 500 pounds.
