Laser leveling system, apparatus and method for building construction
DCFirst Claim
1. A system for establishing a substantially horizontal reference line on a target surface the location of which is fixed relative to first and second support surfaces, the system comprising:
- a post member defining a post axis and having a first end engaging the first support surface and second end engaging the second support surface, where the post member comprises first and second post sections movable relative to each other along the post axis, where the first post section defines the first end of the post member and the second post section defines the second end of the post member;
a mounting member that, in a first state, engages the post member such that the mounting member may be moved along the post axis relative to the post member but may not move radially relative to the post axis;
a locking assembly for selectively securing the mounting member at a desired location along the post member; and
a lighting assembly that generates a light beam at a predetermined angle with respect to true horizontal;
wherein the lighting assembly is supported by the mounting member such that the light beam illuminates a target portion of the target surface and the target portion of the target surface has a predetermined relationship with the desired location along the post member.

Abstract
A leveling assembly to establish elevations in a building structure for installing cabinets, bookshelves, countertops, etc. There is a telescoping mounting post adapted to be positioned in bearing engagement between a floor surface and the top of a doorway, ceiling or other upper surface. A laser that transmits a horizontal laser beam is mounted to a mounting device that can be moved to different positions along the length of the post. Locking devices hold the laser-mounting device in place, and also properly position the post to be in firm engagement with its bearing surfaces. The laser-mounting device can be swung to upper and lower positions.
