US Patent 7562462 Hands-free level indicating device

A hands-free level indicating device includes a level for determining a spatial orientation of a structural member, and an apparatus for securing the level to the structural member. The apparatus includes a U-shaped portion for attaching to the level and a hook-shaped portion for clamping around the structural member. The U-shaped portion and hook-shaped portion can be formed from a single strip of flat material, such as spring steel. A spring is provided to bias the hook-shaped portion in a direction toward the level to allow the apparatus to secure the level to different sizes of structural members. The spring can be a leaf spring that attaches to a base of the U-shaped portion and extends in a longitudinal direction of the level.
