Telescopic leveling instrument
First Claim
1. A telescopic leveling instrument comprising:
- a bubble-level block having orthogonal walls;
one or more telescopic markers extended horizontally from at least one vertical wall of the orthogonal walls of the bubble-level block; and
the bubble-level block being small, light-weight and articulated to be hand-held with a first hand of a user for positioning it against an object while with a second hand of the user, the telescopic markers are employed to measure and to mark selectively in relationship to the object.

Abstract
A telescopic leveling instrument has a small and light-weight bubble-level block (1) with orthogonal walls that include a rectangular first end (3) and a rectangular second end (4) from which telescopic markers are extended. The telescopic markers can include circular telescopic tubes (2), square telescopic tubes (11) or rectangular telescopic tubes (12). The bubble-level block is articulated to be finger-held with a first hand of a user for positioning it against an object while with a second hand, the user is utilizing the telescopic markers for measuring and marking a desired position selectively in relationship to the object against which the bubble-level block is being held. Attachable to extendable ends of the telescopic markers can be a selection of marking aids (17, 18, 19, 20, 21, 22, 23, 24). Preferably, the telescopic markers are ruled with distance indicia for fine measurement. The telescopic markers can be attached removably to the rectangular ends for horizontal measurement and levelness marking in a single direction or in oppositely disposed directions from the bubble-level block. Optionally, one or more of the telescopic markers can be attached removably to a bottom of the bubble-level block for measuring and marking verticality, squareness and vertical distances.
