Abstract

An arrangement comprising a laser projection device is used in determining the location of corners in constructing a foundation of a building or other structure. The arrangement is also used in positioning wooden beams perpendicular to one another in a floor frame or similar structure.

Claims

1. A measurement and positioning arrangement for defining a 90 degree angle for positioning the corner of a building foundation, said arrangement comprising:

a first stake being configured to be disposed in the ground;

a second stake being configured to be disposed in the ground a distance from said first stake;

a first string being configured to be tied between said first stake and said second stake;

a laser device;

said laser device consisting essentially of;

a hook structure being configured to hang said laser device from said first string;

at least one laser beam projector being configured to project a laser beam from said laser device perpendicular to said first string; and

a bubble level being configured to permit a user to verify a level position of said laser device with respect to the ground;

a third stake being configured to be disposed in the ground a distance from said first stake and in the path of said laser beam projected from said laser device hanging from said first string;

a fourth stake being configured to be disposed in the ground a distance from said third stake and in the path of said laser beam projected from said laser device hanging from said first string; and

a second string being configured to be tied between said third stake and said fourth stake to intersect with said first string to define a 90 degree angle and a location where a corner of a building foundation will be placed.

3. The arrangement according to claim 1, wherein said laser device has a length of approximately three and a half inches.

2. A measurement and positioning device for defining a 90 degree angle for positioning the corner of a building foundation, said device consisting essentially of:

a hook structure being configured to hang said measurement and positioning device from a string tied between two stakes; and

at least one laser beam projector being configured to project a laser beam from said measurement and positioning device substantially perpendicular to a string from which said measurement and positioning device is suspended to define a 90 degree angle and a location where a corner of a building foundation will be placed.

4. The device according to claim 2, wherein said device has a length of approximately three and a half inches.

5. A measurement and positioning device for defining a 90 degree angle for positioning the corner of a building foundation, said device consisting essentially of:

a hook structure being configured to hang said measurement and positioning device from a string tied between two stakes; and

two laser beam projectors being configured to project two laser beams from said measurement and positioning device away from each other in opposite directions and substantially perpendicular to a string from which said measurement and positioning device is suspended to define a 90 degree angle and a location where a corner of a building foundation will be placed.

6. The device according to claim 5, wherein said device has a length of approximately three and a half inches.
