Abstract
A level including a frame having a reference surface, a level sensor secured to the frame, and an articulated arm pivotally connected at one end to the frame for securing the reference surface to a test surface. The articulated arm includes an inner member pivotally connected to the frame at one end and an outer member extending from a free end of the inner member. The inner member is rotationally biased against the frame while the outer member is pivotally connected to the inner member and rotationally biased against the inner member. The inner and outer members are rotationally biased in opposite directions for folding against the frame. The level may also include spools, idler wheels, take-up fingers, and swivels for supporting the band.
Claims9
A level, comprising:
- a frame having a reference surface;
- a level sensor secured to the frame;
- an articulated arm pivotally connected at one end to the frame for securing the reference surface to a test surface;
- said articulated arm includes an inner member pivotally connected to the frame at one end and an outer member extending from a free end of the inner member;
- said inner member is rotationally biased against the frame;
- said outer member is also pivotally connected to the inner member and rotationally biased against the inner member;
- and
- said inner and outer members are rotationally biased in opposite directions.
A level, comprising:
- a frame having a reference surface;
- a level sensor secured to the frame;
- at least one articulated arm extendable from the frame for clamping the reference surface to a test surface, said articulated arm including an inner member pivotally connected to the frame at one end and a U-shaped outer member pivotally connected at its top end to a free end of the inner member;
- means for rotationally biasing the inner member against the frame;
- means for rotationally biasing the outer member against the inner member;
- and
- said inner and outer members are rotationally biased in opposite directions.
