Circle and bi-directional ray drawing device

Description

FIG. 1 is an elevated, perspective view of the circle and bi-directional ray drawing device, which includes a 360° protractor pivotally connected to a pair of radius arms;

FIG. 2 is a top plan view of the embodiment shown in FIG. 1;

FIG. 3 is a bottom plan view of the embodiment shown in FIG. 1;

FIG. 4 is a right side edge view taken perpendicularly with respect to the radius arms of FIG. 1;

FIG. 5 is an upper edge view of the embodiment shown in FIG. 1 taken perpendicular to the view of FIG. 4;

FIG. 6 is a lower edge view of the embodiment shown in FIG. 1 taken perpendicular to the view of FIG. 4; and,

FIG. 7 is a left side edge view taken perpendicularly with respect to the radius arms of FIG. 1.

The thicknesses shown in FIGS. 1, 4, 5, 6, and 7 of the disk and the radius arm are not necessarily to scale, due to line thicknesses and/or other illustration limitations. Typically, the thicknesses of these layers will each be less than about 1 centimeter, with no relative thicknesses being implied by the drawings. Additionally, certain design features are shown in phantom or broken lines for illustrative purposes only, thereby forming no part of this claimed invention.

Claims
