Abstract
Abstract A safety post for construction workers and the like comprising angle structure having integral horizontal and vertical legs, the horizontal leg having a clamp including fixed and movable tapered members opposed on the underside of the horizontal leg for detachably gripping structural beams, the movable member having a portion loosely encircling the horizontal leg with a fulcrum below and screw structure operable from above to pivot and tighten the movable member; the vertical member having a column which may optionally be height-adjustable by telescoping of separate lengths, and which terminates at the top in a pair of fixed arcuate horns with the ends inward turned and overlappingly spaced for retaining a safety cable therebetween while permitting workmen to walk their safety lines along the cable without need to unsnap the safety lines at the safety post.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
106 words
A post for detachable affixation on flanged beams and the like to support a workers' safety-line-securing cable, comprising: a horizontal leg, a vertical leg, means for joining all said legs, means for clamping the horizontal leg to a said flanged beam, and the vertical leg having fixed thereto means including inwardly-turned overlapping horn structure having spacing for detachably engaging an intermediate portion of a said cable upon rotation thereof relative to a said cable, said spacing being proportioned for permitting a said workers' safety line on a said cable to be rotated in said spacing and passed along a said cable for passing a said post.
Claim 2
Dependent Claim
