Abstract
Disclosed is an adjustable grade finder that can be used to measure one or both of a relative distance delta between two points or an absolute distance delta between two points with no or minimal calculations. For one embodiment the adjustable grade finder is configured to be associated with a leveling pole so that the combination provides a tool for making measurements that represent a relative distance delta between two or more points while eliminating the need to perform mathematical calculations thereby simplifying the task of leveling a grade over an area of ground.
Claims20
An adjustable grade finder comprising:
- an outer member defining an elongated OM-structure having an OM-first-end and an opposing OM-second-end wherein said OM-structure is at least partially hollow thereby defining an OM-outside perimeter and an OM-inside perimeter;
- an inner member defining an elongated IM-structure having an IM-first-end, an opposing IM-second-end, and wherein the outer perimeter of said IM-structure is smaller than said OM-inside perimeter and wherein said IM-first-end is configured for being inserted into and movably associated with said OM-first end to form a telescopic association;
- a measurement scale associated with said IM-first-end;
- and
- a measure window defined by said outer member and configured to allow a user to view said measurement scale.

- an inner member defining an elongated IM-structure having an IM-first-end, an opposing IM-second-end, and wherein the outer perimeter of said IM-structure is smaller than said OM-inside perimeter and wherein said IM-first-end is configured for being inserted into and movably associated with said OM-first end to form a telescopic association;
- a measurement slide defining a MS-structure having a MS-first-end and an opposing MS-second-end wherein said MS-structure is hollow thereby defining a MS-outside perimeter and a MS-inside perimeter and wherein said MS-inside perimeter is larger than said OM-outside perimeter and wherein said OM-structure is inserted through said MS-structure;
- a measurement scale that is one of (a) defined by and (b) associated with said outer member;
- and
- a measurement window defined by said measure slide and configured to allow a user to view said measure scale.
A method of determining the distance delta between two points, said method comprising the steps of:
- positioning a substance emitter a predefined distance away from the location of the points to be measured so that the height of said substance emitter is vertically and horizontally stable and so that the substance being emitted travels across the surface for which the measurements are to be taken;
- positioning, at a first point, an adjustable measurement tool comprising a measurement scale and one of (a) an adjustable grade finder comprising a stationary member and a moving member, and (b) an adjustable grade finder comprising a stationary member and a moving member wherein a leveling pole is mechanically associated with said moving member;
- wherein one end of said stationary member is supported by the surface being measured;
- selectively moveably associating a substance detector with one of (a) said movable member, and (b) said leveling pole and moving said substance detector along one of (a) said movable member, and (b) said leveling pole until said substance detector is indicating the detection of said substance;
- securing said substance detector so that it does not move relative to said one of (a) said movable member and (b) said leveling pole;
- moving said adjustable grade finder to a second point so that one end of said stationary member is supported by the surface being measured;
- and
- moving as necessary said movable member until said substance detector is indicating the detection of said substance thereby causing the adjustable grade finder measurement scale to indicate a distance delta.
