Abstract:
A constructional laser for generating at least one of optical plumb beam and leveling beam, comprising a housing (2); an electro-optical system (4) for generating at least one of visible plumb light beam (5a) and visible horizontal light beam (5b) and which is firmly focused at least in one direction, the electro-optical system (4) being located in the housing (2) and being self-aligning relative to the housing (2) under a gravity force G within a self-leveling region (&agr;); and a stand (7) fixedly secured to the housing (2) for mounting the housing on a bearing support (6), the stand (7) being at least one of continuously pivotable about a pivot axis (A) transverse to the light beam (5a, 5b) in an angular region (&bgr;) of greater than (20Â°) for rough leveling of the housing (2) with respect to the support and discreetly pivotable in angular steps encompassing the self-leveling region (&agr;), and lockable in a pivotal position thereof, and wherein the pivot axis (A) is spaced from a center point of two opposite side surfaces of the housing (2) and lies in a plane extending transverse to the opposite side surfaces of the housing.
