Patent ID: 7367129

Claim:
A leveling device for use on a work surface, comprising: a body defining an engagement surface facing in a first direction and one or more manually engageable surfaces facing in a direction away from the first direction; a light beam emitter contained within the body for emitting a light beam exteriorly of the body in a predetermined orientation relative to the body; and an engagement arrangement associated with the body for selectively maintaining the body in position on the work surface, including a plurality of spaced apart engagement members and an adhesive carried by the plurality of engagement members, wherein the plurality of engagement members are movable between a retracted position in which the adhesive is positioned inwardly of the engagement surface of the body and an extended position in which the adhesive is positioned outwardly of the engagement surface of the body for engagement with the work surface to selectively maintain the body in position on the work surface; wherein each engagement member is movable from the retracted position to the extended position in response to manual engagement of an actuator which is manually accessible from one of the manually engageable surfaces of the body; and wherein the body and the plurality of engagement members associated with the body are configured and arranged such that an adjacent pair of the actuators are spaced sufficiently close together to enable a user to simultaneously manually move the pair of actuators inwardly relative to the body using one hand, wherein the simultaneous inward movement of the pair of actuators is operable to simultaneously move an associated pair of engagement members from the retracted position to the extended position to engage the body with the work surface.
