ABSTRACT:
A combination tape measure and straight edge apparatus includes a first straight edge segment which includes an outer edge and an inner edge and which has a predetermined thickness. A tape measure assembly includes a bottom side, and a hinge assembly is connected between the bottom side of the tape measure assembly and the inner edge of the first straight edge segment. The hinge assembly is adapted to permit the tape measure assembly to be rotated with respect to the first straight edge segment from a storage orientation to either a first in-use orientation or a second in-use orientation or from an in-use orientation to a storage orientation. The first straight edge segment includes a first end and a second end. A guide member is connected to the outer edge of the first straight edge segment. The guide member is connected to the first straight edge segment at a right angle. A second straight edge segment may be connected to the first end of the first straight edge segment. The second straight edge segment is oriented perpendicular to the first straight edge segment. A third straight edge segment may be connected between the first straight edge segment and the second straight edge segment. The first straight edge segment, the second straight edge segment, and the third straight edge segment form a unified, integrated right triangle.
