Automatic level and plumb tool |
摘要 |
A self-leveling plumb, level and pointing tool uses a visible laser diode to project light beams in two modes through two windows. Accurate, low cost structures for generating level and plumb beams and planes of light are disclosed. In principal embodiments, all leveling is accomplished using a very flexible coil spring as a pendulum element, a chain link connection in combination with such a spring, or a point contact suspension. Several accessories are disclosed for use with the laser tool, as well as other embodiments.
