Deformable safety hook
First Claim
1. A hook for supporting an article having a base portion for mounting said hook,an article supporting portion extending from said base portion for supporting an article thereon, an article retaining portion extending generally upwardly and outwardly from said article supporting portion, said article retaining portion, said base portion and said article supporting portion formed as solid integral portions from a material having an initial modulus of elasticity in tension of from between about 2,000 psi to about 40,000 psi up to about 5% strain in tension and an initial modulus of elasticity in compression of from between about 1,000 psi to about 40,000 psi up to about 5% strain in compression, said article supporting portion having a base section adjacent said base portion and an outer section adjacent said article retaining portion, said base section having a greater vertical moment of inertia than the vertical moment of inertia of said outer section, said base section having a vertical moment of inertia greater than the horizontal moment of inertia of said base section whereby said article retaining portion is flexible and resiliently deformable in all directions so that when said hook is impacted, it can flex and decrease the possibility of injury and whereby said hook will return substantially to its original shape.

Abstract
A safety hook is provided for supporting an article on a structure. The hook has a base portion for mounting the hook to the structure and an article supporting portion which extends from the base portion. The article supporting portion is provided to support the article on the structure to which the hook is mounted. The hook also has an article retaining portion extending generally upwardly from the article supporting portion and operates to keep the article on the article supporting portion. The article retaining portion is formed from a material and has a configuration that allows the article retaining portion to flex and resiliently deform upon impact.

10. A hook for supporting an article having
a base portion for mounting said hook, an article supporting portion extending from said base portion for supporting an article thereon, said article portion having a base section adjacent said base portion and terminating in an outer section, said article supporting portion formed from upper and lower reinforcing ribs extending from said base portion where they are spaced from each other and are positioned closer to each other as they extend toward said outer section, an article retaining portion extending generally upwardly and outwardly from said article supporting portion, said article retaining portion and said article supporting portion formed from a material having an initial modulus of elasticity in tension of from between about 2,000 psi to about 40,000 psi up to about 5% strain in tension and an initial modulus of elasticity in compression of from between about 1,000 psi to about 40,000 psi up to about 5% strain in compression whereby said article retaining portion is flexible and resiliently deformable in all directions so that when said hook is impacted, it can flex and decrease the possibility of injury and whereby said hook will return substantially to its original shape.
