Patent ID: 8622448

Claim:
A connection fixture for engaging a lip of a structure, comprising: a. an outer angle iron comprising a length of structural angle having a vertical portion defining a shackle receiving hole therein and a horizontal portion wherein the vertical portion and the horizontal portion intersect to form a lower right angle, further comprising a plurality of pins distributed along the length thereof protruding upwardly from the horizontal portion thereof; b. a plurality of fasteners distributed along the length of the outer angle iron and attachable to the vertical portion of the outer angle iron such that the fasteners when attached protrude inwardly from the vertical portion of the outer angle iron; and c. an inner angle iron comprising a length of structural angle having a vertical portion defining a shackle receiving hole therein and a horizontal portion wherein the vertical portion and the horizontal portion intersect to form a lower right angle, further defining a plurality of holes in the horizontal portion of the inner angle iron distributed along the length thereof and a plurality of vertical slots in the vertical portion of the inner angle iron distributed along the length thereof; wherein the outer angle iron and the inner angle iron are capable of mating with one another in such a way that the vertical and horizontal portions of the inner angle iron are positioned adjacent the vertical and horizontal portions of the outer angle iron, and the fasteners are attached to the vertical portion of the outer angle iron through the slots in the vertical portion of the inner angle iron thereby retaining the inner angle iron in a vertically slideable relationship with respect to the outer angle iron; wherein the pins protruding from the horizontal portion of the outer angle iron are positionable to align with the plurality of holes in the horizontal portion of the inner angle iron and holes in the lip of the structure in such a way that the pins can pass through the holes in the lip of the structure and the holes in the horizontal portion of the inner angle iron; and wherein the shackle receiving hole of the outer angle iron is positionable to align with the shackle receiving hole of the inner angle iron.
