Abstract
A gated safety hook includes a structural, load bearing frame, a gate, and a user actuated catch. The gate closes automatically in response to an object being mounted on the hook, the catch automatically moves to lock the gate closed in response to an object being mounted on the hook, and the gate cannot be opened with an object mounted on the hook without engaging against the object.
Claims32
A safety hook for mounting an object to a structure, the safety hook comprising:
- a frame having an upper portion, a tip, a hook-shaped portion extending from the upper portion to the tip to define a mount opening that receives an object mounted on the hook, and a gap extending between the tip and the upper portion to allow an object to be inserted into the mount opening;
- a gate having an upper arm and a lower arm that are fixed relative to each other, the gate mounted to the hook to pivot between an open position and a closed position, in the open position the upper arm is spaced from the gap to allow an object to be inserted into the mount opening and the lower arm extends across the mount opening to be engaged by an object that is inserted into the mount opening, in the closed position the upper arm extends across the gap to prevent an object from exiting the mount opening through the gap and the lower arm is positioned adjacent the hook-shaped portion to abut an object mounted on the hook-shaped portion in response to movement of the gate toward the open position;
- and
- a user actuated catch mounted to the frame to move between a retain position, a lock position, and a release position, in the retain position the catch is engaged with the gate to retain the gate in the open position, in the lock position the catch is engaged with the gate to retain the gate in the closed position, and in the release position the catch is disengaged from the gate to allow the gate to move between the closed position and the open position.

- a frame having an upper portion, a tip, a hook-shaped portion extending from the upper portion to the tip to define a mount opening that receives an object that is to be mounted on the hook, and a gap extending between the tip and the upper portion to allow an object to be inserted into the mount opening;
- a gate having an upper arm and a lower arm that are fixed relative to each other, the gate mounted to the hook to pivot between an open position and a closed position, in the open position the upper arm is spaced from the gap to allow an object to be inserted into the mount opening and the lower arm extends across the mount opening to be engaged by an object that is inserted into the mount opening, in the closed position the upper arm extends across the gap to prevent an object from exiting the mount opening through the gap;
- and
- a user actuated catch mounted to the frame to move between a retain position, a lock position, and a release position, in the retain position the catch is engaged with the gate to retain the gate in the open position, in the lock position the catch is engaged with the gate to retain the gate in the closed position, and in the release position the catch is disengaged from the gate to allow the gate to move between the closed position and the open position;
- wherein the catch is configured to move from the retain position to the release position in response to the gate moving from the open position toward the closed position.
