Patent attributes
A hook formed into a body having a hook shape and having a neck and fabricated from nonferromagnetic material with the body having a first end and a second end. The neck is proximate the first end. The hook also includes a closure that is fabricated from nonmagnetic ferromagnetic material, other nonmagnetic materials, and magnetic ferromagnetic materials, and having a first closure end and a second closure end, the closure being pivotally and/or pivotally and slidably attached to the body and positioned to span a gap between the second end of the hook and the body. There is at least one magnet fixedly attached to the neck, so the at least one magnet holds the closure in a closed position that spans the gap such that the hook encloses a defined space in the closed position.
