Abstract
The drafting instrument of the invention generally comprises a triangular integrally formed substantially planar construction having three perimeter legs, interconnected end to end to form the triangular configuration and define an open space in the interior of the body, and one interior leg extending across the open space to form interior complementary angles to the angles formed at the respective intersections of the perimeter legs. The instrument is provided in two primary embodiments, the first adapted as a 30/60 degree triangular instrument and the second as a 45 degree triangular instrument. The instrument includes a plurality of glide points extending outwardly from one or both faces of the instrument to support the instrument slightly above the surface upon which it is used, and further includes a handle assembly disposed near the intersection of two of the perimeter legs of the instrument. In the preferred embodiments of the invention the handle is slideably disposed in an aperture and retained therein by thin end caps, allowing the handle to slide freely through the aperture in a direction perpendicular to the plane of the instrument.
