Patent ID: 8661698

Claim:
Spirit level comprising a profiled body, as spirit level body, with a bottom wall which makes available a first outer surface in the form of a measurement surface, a headwall facing this bottom wall, with a second outer surface, which runs at least in sections parallel to the measurement surface, and is in the form of a head surface, as well as side walls, which connect the bottom wall to the head wall, and which present, on the one hand, a first outer lateral face, and, on the other hand, a second outer lateral face, where the profiled body presents at least one bubble vial body, whose bubble vial can be optically detected, and where the profiled body, with respect to its vertical axis which runs perpendicularly to the measurement surface, presents a design on the lateral face that is asymmetric over the length of the profiled body, and a lateral face, as the first lateral face viewed in the longitudinal direction of the profiled body, presents a channel-shaped course, wherein the second lateral face comprises a first section, which runs on the head side and presents a convex course, and a subsequent second section whose separation from the vertical axis of the profiled body increases starting from the first section in the direction of the measurement surface.
