Abstract: A wheeled backpack includes a bottom frame member, a fabric bag portion, a pair of laterally spaced wheels, a pair of side frame members, and a telescoping handle that can move between a retracted position and an extended position where the handle can be grasped by a user to roll the backpack on the wheels. The handle is located so that there is little or no fore and aft offset of the center of mass/gravity of the backpack, which minimizes torquing on the handle and associated pivoting of the backpack in a user's hand when the backpack is lifted by the handle with the handle in the retracted position.

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.
