Leveling rod and leveling method

A method for using a leveling instrument and a leveling rod to establish at least one predetermined elevation relative to a benchmark elevation at one or more locations on a construction site without the need for mathematical computations, the method comprising the steps of:

• providing a leveling rod comprising elongated base and sliding rail members slidingly interconnected in lapped relation, the sliding rail member being selectively fixedly positionable along the base rail member in a plurality of positions, the base rail member having opposing front and rear longitudinal surfaces, an upper end, and a lower end comprising a foot portion, and the sliding rail member having opposing front and rear surfaces, and upper and lower ends;
• providing at least one elongated, self-supporting, blank measuring insert removably mateable with the front surface of the sliding rail member;
• providing on the measuring insert only indicia for identifying the relative positions of the benchmark elevation and the at least one predetermined elevation;
• calibrating the leveling rod to the benchmark elevation by positioning the foot portion of the leveling rod on the benchmark elevation, and slidingly moving the sliding rail member along the base rail member until the indicia on the measuring insert corresponding to the benchmark elevation is aligned with the leveling instrument;
• and
• establishing the at least one predetermined elevation at one or more locations on the construction site by positioning the foot portion of the leveling rod on a support surface at each of the one or more locations, and modifying the elevation of the support surface until the indicia on the measuring insert corresponding to the at least one predetermined elevation is aligned with the leveling instrument.

A method for employing both a leveling instrument and a single leveling rod to automatically establish at least a second elevation at one or more locations on a construction site using a known measurement for establishing a first elevation in relation to a benchmark elevation, where the distance between the first and at least second elevations is constant, the method comprising the steps of:

• providing a leveling rod having a lower end comprising a foot portion, and a measuring scale;
• providing a measuring attachment for the leveling rod, the measuring attachment comprising a bracket mountable to the leveling rod and adapted for longitudinal sliding movement there along, the bracket including an indicator for identifying a first position on the measuring scale corresponding to a known measurement for establishing a first elevation, and an elongated rail member extending from the bracket in a direction generally parallel to the axis of movement of the bracket along the leveling rod, the rail member including at least one indicator for identifying at least a second position that is different from the first position, the at least one indicator being selectively positionable along the rail;
• fixedly positioning the at least one indicator a predetermined distance from the indicator for identifying the first position corresponding to the constant distance between the first and at least second elevations;
• calibrating the leveling rod with the leveling instrument by placing the foot of the leveling rod on the benchmark elevation, and adjusting the indicator for identifying the first position to a position on the measuring scale corresponding to a starting position;
• adjusting the indicator for identifying the first position to a position on the measuring scale corresponding to the known measurement for establishing the first elevation in relation to the benchmark elevation;
• and
• establishing the at least second elevation at one or more locations by adjusting the position of the measuring attachment to bring the at least one indicator for identifying the at least second position to a position on the measuring scale corresponding to the known measurement for establishing the first elevation in relation to the benchmark elevation, positioning the foot of the leveling rod on a support surface at the one or more locations, and modifying the elevation at the one or more locations as necessary until the indicator for identifying the first position is aligned with the leveling instrument.

A method for employing both a leveling instrument and a single leveling rod to automatically establish a lower elevation at one or more locations on a construction site using a known measurement provided for establishing a first elevation in relation to a benchmark elevation, where the distance between the lower and higher elevations is constant, the method comprising the steps of:

• providing a leveling rod having a lower end comprising a foot portion, and a measuring scale;
• providing a cut attachment including first and second hingedly connected segments, the first segment being slidingly interconnectable to the leveling rod and selectively fixedly positionable in a plurality of positions along the leveling rod, the cut attachment being characterized by a folded condition, wherein the first and second segments are arranged in lapped relation, and an unfolded condition, wherein the first and second segments are arranged end-to-end, and the second segment having a lower end comprising a foot portion;
• fixedly positioning the first segment along the leveling rod such that, in the folded condition of the cut attachment, the second segment does not extend beyond the lower end of the leveling rod, and in the unfolded condition of the cut attachment, the second segment extends beyond the lower end of the leveling rod a distance that is equal to the distance between the higher and lower elevations;
• with the cut attachment in the folded condition thereof, calibrating the leveling rod with the leveling instrument by placing the foot of the leveling rod on the benchmark elevation, and aligning the leveling instrument with a position on the measuring scale corresponding to a starting position;
• identifying on the measuring scale of the leveling rod a position corresponding to the known measurement for establishing the higher elevation;
• and
• establishing the lower elevation by placing the cut attachment in the unfolded condition thereof, positioning the foot portion of the second segment on a support surface at the one or more locations, and modifying the elevation at the one or more locations as necessary until the position on the measuring device corresponding to the known measurement for establishing the higher elevation is aligned with the leveling instrument.

• an elongated base rail member having opposing front and rear longitudinal surfaces, an upper end, and a lower end comprising a foot portion;
• an elongated sliding rail member having opposing front and rear surfaces, and upper and lower ends;
• the front surface of the base rail member and the rear surface of the sliding rail member each having one or the other of complementary tongue and groove portions whereby the base and sliding rail members are slidingly interconnected in lapped relation, and the sliding rail member further being selectively fixedly positionable along the base rail member in a plurality of positions;
• and
• an elongated, self-supporting measuring insert removably mateable with the front surface of the sliding rail member
• a cut attachment including first and second hingedly connected longitudinal segments, the cut attachment being characterized by a folded condition, wherein the first and second segments are arranged in lapped relation, and an unfolded condition, wherein the first and second segments are arranged end-to-end;
