Description
Spirit level Field of the Invention This present invention relates to spirit levels in general and to spirit levels for setting a spaced apart pair of upright studs in particular.
Background of the Invention US Design Patent No. D805,928 to Ben Josef et al. shows a spirit level for setting a spaced apart pair of adjacent upright studs at either a first standard stud separation or a second standard stud separation measured between their midpoints.
First and second standard stud separations are either 400 mm and 600 mm, respectively, or 417 mm and 625 mm, respectively. Upright studs can be made from steel or wood. Upright studs have one of three standard stud widths: 40 mm, mm and 60 mm.
US Design Patent No. D805,928 spirit level is designed for use with one standard stud width only and includes a main body having a leveling surface to be set on a horizontal surface and a bubble vial for providing a visual indication of an inclination of the horizontal surface with respect to the horizontal. The main body includes a left stud slot and a central stud slot spaced apart from the left stud slot at their midpoints at the first standard stud separation and a right stud slot spaced apart from the left stud slot at their midpoints at the second standard stud separation. The stud slots can be provided with magnets for hands free setting a spaced apart pair of adjacent upright metal studs.There is a need for a spirit level for use for setting a spaced apart pair of adjacent upright studs of more than one standard stud width.
Summary of the Invention The present invention is for spirit levels for use for setting a spaced apart pair of adjacent upright studs of more than one standard stud width. The spirit levels include stud slots having the longest 60 mm standard stud width and a stud slot reduction arrangement for reversibly shortening the longest 60 mm standard stud slot width to a shorter standard stud width. The spirit levels can be configured for reversible shortening the longest 60 mm standard stud width to one of shortest 40 mm standard stud or the middle length 50 mm standard stud width only. Alternatively, the spirit levels can be configured for reversibly shortening the longest 60 mm standard stud width to either the shortest 40 mm standard stud width or the middle length 50 mm standard stud width. The spirit levels can be configured for use with upright studs of different stud widths and/or different standard stud separations between the midpoints of spaced apart pair or upright studs.Spirit levels can be configured for setting a single spaced apart pair of upright studs or multiple spaced apart pairs of upright studs. The spirit levels preferably store a stud slot reduction arrangement when not deployed for shortening stud slot widths. The stud slot reduction arrangements preferably include a set of stud slot reducers which are slidingly inserted into stud slots for reducing their stud slot width and slidingly removed therefrom for restoring their stud slot width to their non-shortened stud slot width.One stud slot reduction arrangement includes a set of discrete stud slot reducers configured for preferably downward sliding insertion into stud slots in a front elevation view of a spirit level for shortening their stud slot widths. The stud slot widths are preferably shortened by the insertion of a pair of stud slot reducers as opposed to a single stud slot reducer. A spirit level preferably includes a stud slot reducer storage magazine configured for storing its set of discrete stud slot reducers when not in use. Another stud slot reduction arrangement includes a set of screw-operated stud slot reduction mechanisms each having a stud slot reducer configured for repeatedly selectively deployable between a storage position and a stud slot reduction position. The stud slot reducers preferably undergo a linear displacement between their storage position and their stud slot reduction position.
