Abstract

A laser-level device has a body having a length, a height and a width, with a base, sides and a top, an upper slider engaging a longitudinal track along the top of the device, connected through a lengthwise channel to a lower slider element within the body, a laser module carrying a laser, engaged in a track curved in an arc of about ninety degrees, and a first link engaged pivotally to the lower slider element on a first end and pivotally to the laser module on a second end. The laser module follows the track curvature in response to translation of the slider along the longitudinal track from a fully retracted position to a fully extended position, and the laser emits a laser beam through the central, lengthwise channel, the beam moving in an arc determined by the track curvature.
