Patent ID: 7922220

Claim:
A safety mechanism comprising: a first force resisting means; a hook comprising a gate having first and second ends, a fulcrum point intermediate said first and second ends and a first rotational axis proximate said second end; and, a second force resisting means, wherein said first force resisting means is intermediate said fulcrum point and said first rotational axis, and wherein a force applied to said first end is transmitted toward said first rotational axis via said fulcrum point and said first force resisting means prevents transmission of said force to said first rotational axis, wherein said hook further comprises a hook body having two sides, a first through-hole in aligned position with said first rotational axis and said first force resisting means comprises a first protrusion extending from each of said two sides of said hook body and each of the first protrusions is proximate said first through-hole and wherein said gate further comprises spaced apart parallel gate side walls, and wherein said hook further comprises a release lever having spaced apart parallel lever side walls and a second rotational axis, said lever side walls comprising a first locking means, said gate side walls comprising a second locking means arranged to complimentarily engage said first locking means, said hook body further comprises a second through-hole in aligned position with said second rotational axis and said second force resisting means comprises a second protrusion extending from each of said two sides of said hook body and each of the second protrusions is proximate said second through-hole, and wherein said second force resisting means is arranged to engage said second protrusions when said force is applied to said gate.
