Abstract
A modular level, which functions as a level for construction trades, comprises a pair of levels which combine to function as one level. The levels also may be separated so that each level may be individually used as a level. An adjustment mechanism calibrates and adjusts the position of the vial relative to the reference edge.
Claims13
A modular level for use in construction trades and the like comprising:
- a master level having opposed longitudinally spaced ends and a linear reference edge extending between said ends and defining a central receptacle and having at least one level indicator positioned at a location spaced from said receptacle;
- an auxiliary level receivable in said receptacle and having opposed longitudinally spaced ends, a linear reference edge extending between said ends and at least one level indicator, said opposed ends and linear reference edge being fully receivable in said receptacle;
- retainer means for releasably retaining said auxiliary level to said master level;
- and
- coupling means for releasably coupling said master frame and auxiliary level and end-to-end relationship so that said master frame linear reference edge is collinear with said auxiliary level linear reference edge.

A modular level system for use in construction trades and the like comprising:
- a first level having opposed longitudinally spaced ends, a linear reference edge extending between said ends and at least one level indicator;
- a second level having opposed longitudinally spaced ends, a linear reference edge extending between said ends and at least one level indicator;
- and
- coupling means on said first and second levels for releasably coupling said first level and second level in at least one of a linear relationship and perpendicular relationship, so that in said linear relationship said first level reference edge is collinear with said second level reference edge and in said perpendicular relationship said first level linear reference edge is perpendicular to said second level linear reference edge, said coupling means comprising a threaded bolt which is projectable through one of said first level and a threaded receiver which is accessible through an end of said second level, said bolt being threadably engageable with said receiver.
