Multiple angle compact spirit level
The level with a generally u-shaped or round, rigid frame. The outer surface is comprised of a number of planar reference faces that are at different fixed angles to a spirit vial mounted in the frame. Optionally, magnets are embedded in the reference faces. Optionally, there are grooves in the reference faces.
1. A spirit level comprising:
(a) a rigid, generally U-shaped frame having an outer surface and an inner surface, said inner surface being generally concentric with said outer surface and having a pair of opposed walls;
(b) at least one spirit vial mounted to said frame between said opposed walls and having an axis; and
(c) said outer surface comprised of at least three reference faces at predetermined fixed angles to said vial axis, said predetermined angles includes at least 0 degrees, 90 degrees, and third angle between 0 degrees and 90 degrees.
2. The spirit level of claim 1 wherein at least one of said reference faces has an imbedded magnet.
3. The spirit level of claim 1 wherein at least one of said reference faces has a groove.
4. A spirit level comprising:
(a) a rigid, generally circular frame having an outer surface and an inner surface, said inner surface being generally concentric with said outer surface and having a pair of opposed walls;
(b) at least one spirit vial mounted to said frame between said opposed walls and having an axis; and
(c) said outer surface comprised of at least three reference faces at predetermined fixed angles to said vial axis.
5. The spirit level of claim 4 wherein said predetermined angles include at least 0 degrees, 90 degrees, and third angle between 0 degrees and 90 degrees.
6. The spirit level of claim 4 wherein at least one of said reference faces has an imbedded magnet.
7. The spirit level of claim 4 wherein at least one of said reference faces has a groove.
