摘要： A level with a level indicating vial is disclosed. The level includes a frame that defines at least one substantially flat exterior surface configured to be placed against a reference surface. The frame defines a plurality of interior surfaces. The level also includes a vial for indicating an orientation of the reference surface, and a vial holder for holding the vial in an orientation relative to the flat exterior surface of the frame. The vial holder is configured to cooperate with one of the interior surfaces of the frame to define a cavity when the vial holder contacts the interior surface. The level also includes an adhesive disposed in the cavity to secure the vial holder to the frame.

摘要： The present invention comprises a retractable rule assembly that includes a housing assembly and a reel rotatably mounted in the housing assembly. An elongated blade formed of a ribbon of metal is mounted on the reel. One end of the blade is connected to the reel. The blade is constructed and arranged with respect to the housing assembly to extend from a position tangential to the reel outwardly through a spaced opening in the housing assembly. A coil spring that is formed of a ribbon of metal has a construction and arrangement between the housing assembly and the reel to rotate the reel in the housing assembly in a direction to wind the elongated blade about the reel when the blade is extending outwardly of the housing assembly opening. The blade has a “normal” concavo-convex cross-sectional configuration when extended and has a flat cross-sectional configuration when it is wound about the reel so that the wound reel is disposed about the reel in an abutting volute coil formation. A blade holding assembly is provided which can hold the blade in any position of extension outwardly of the housing assembly opening and to release the blade from any position in which it is held. The blade has a width in its flattened configuration thereof within the range of 1.10″-1.5″ and a height in its concavo-convex configuration thereof within the range of 0.25″-0.40″.

摘要： A rule assembly includes a housing assembly and a reel rotatably mounted in the housing assembly. An elongated blade formed of a ribbon of metal having one end connected to the reel is constructed and arranged with respect to the housing assembly to extend from a position tangential to the reel outwardly through a spaced opening in the housing assembly in a normal concavo-convex cross-sectional configuration and to wind onto the reel in an abutting volute coil formation in a flattened cross-sectional configuration. The blade has an end hook member on the free end thereof. The end hook member is formed of sheet metal of a predetermined thickness to include a concavo-convex mounting portion having a U-shaped hook portion bent at a generally right angle from an end thereof. The end hook member is mounted on the free end of the blade with the mounting portion thereof secured in limited sliding engagement with a concave side of the free end of the blade so that the rule can be measured externally from an exterior surface of the U-shaped hook portion or internally from an interior surface of the U-shaped hook portion. The U-shaped hook portion includes a bight section extending transversely from a convex side of the free end of the blade and spaced leg sections extending beyond transversely spaced corners of the free end of the blade.

摘要： A rule assembly includes a housing assembly and a reel rotatably mounted in the housing assembly. An elongated blade formed of a ribbon of metal having one end connected to the reel extendable outwardly through a spaced opening in the housing assembly. An end hook member on the free end of the blade includes a hook portion and a mounting portion extending generally perpendicular from the hook portion. The housing opening has a height dimension which exceeds the height dimension of the hook member mounting portion and its connection with the free end of the blade an amount which is at least approximately equal to an amount the hook portion extends below the bottom end surface of the housing assembly when at the housing opening.
