DOUBLE LOCKING SAFETY SNAP HOOK
First Claim
Patent Images
1. A safety snap hook comprising:
- a body including an base portion, a hook portion defining a hook throat opening, and a shank connected between said base portion and said hook portion;
a first resilient member;
a gate connected pivotally to said base portion and biased by said first resilient member to close said hook throat opening, said gate having an aperture adjacent to said base portion, and a locking surface defining an end of said aperture distal from said base portion;
a second resilient member;
a trigger connected pivotally to said base portion and extending through said aperture in said gate, said trigger being biased by said second resilient member to press against said locking surface for preventing rotation of said gate relative to said base portion, said trigger having a free end operable to remove said trigger from said locking surface;
a third resilient member;
a locking member connected pivotally to said shank and biased by said third resilient member to a locking position whereat rotation of said gate relative to said base portion is prevented, said locking member having a free end operable to move said locking member to a release position whereat rotation of said gate relative to said base portion is allowed;
wherein, when said free ends of said trigger and said locking member are rotated toward said base portion to remove said trigger from said locking surface and rotate said locking member to said release position, said gate can be rotated relative to said base portion to open said hook throat opening.

Abstract
A safety snap hook includes a body defining a hook throat opening, a pivotable gate biased to close the hook throat opening, a pivotable trigger extending through an aperture in the gate and biased to press against a locking surface of the gate, and a pivotable locking member biased to a locking position whereat rotation of the gate relative to the body is prevented. When free ends of the trigger and the locking member are rotated toward the body to remove the trigger from the locking surface and rotate the locking member to a release position, the gate can be rotated relative to the body to open the hook throat opening.
