Vertical side gradation in the a bulls-eye level for surface and edge levellingleveling, along with means for angle measurement

Abstract

The present invention describes a bulls-eye level to be used for levelling of surface and edges. The bulls-eye level includes a fluid case containing a fluid inside, an indicator i.e. bubble to indicate level and calibrated markings for measurement. The bulls-eye level can comprise of any degree or any sort of gradation that is printed on the surface of the bullseye level, which can be used to track the movement of the bubble along the side edges. The gradations present in the bulls-eye level can be used for surface and edge levelling in both vertical and horizontal positions, along with angle measurement. The gradations of the bulls-eye level are printed either on the outer surface or the inner surface, which is clearly visible with the luminous yellow color clear fluid inside. The gradations of the hulls-eye level comprises starts from 0° to 360° both in vertical and horizontal positions.

I claim: 
     
         1 . A bulls-eye level indicator for use in indicating the level of a surface, comprising:
 a transparent case containing a fluid   a fluid which substantially fills said volume of the transparent case with the formation of a bubble,   a plurality of angle measurement lines formed on said transparent case, said plurality of angle measurement lines indicating said two-dimensional angle of inclination.   
     
     
         2 . A bulls-eye level indicator for use in indicating the level of the surface as claimed in  claim 1 , wherein the transparent case is a substantially circular disk shape. 
     
     
         3 . A bulls-eye level indicator for use in indicating the level of the surface as claimed in  claim 1 , wherein the said liquid is a colored and clear liquid which is filled in the said transparent case such that a bubble is formed. 
     
     
         4 . A bulls-eye level indicator for use in indicating the level of the surface as claimed in  claim 1 , wherein the said bubble acts as the level indicator in two dimensions. 
     
     
         5 . A bulls-eye level indicator for use in indicating the level of the surface as claimed in  claim 1 , wherein the tracking lines and circles are etched or printed on the horizontal surface of the case such that it tracks the position of the bubble. 
     
     
         7 . A bulls-eye level indicator for use in indicating the level of the surface as claimed in  claim 1  claim, wherein the said plurality of angle measurement lines measures the two-dimensional angle of inclination. 
     
     
         8 . A bulls-eye level indicator for use in indicating the level of the surface as claimed in  1 , wherein the said lines of measurement are etched on the vertical surface (edge of the disk shaped case) and the horizontal surface of the circular disk shaped case. 
     
     
         9 . A bulls-eye level indicator for use in indicating the level of the surface as claimed in  claim 1  wherein the said lines of measurement are degree gradations from zero degrees to three hundred and sixty degrees covering the circumference of the disk-shaped case. 
     
     
         10 . A bulls-eye level indicator for use in indicating the level of the surface as claimed in  claim 1 , wherein the said bubble is at highest point in the vertical position of the level indicator and the bubble is at the center of the bull-eye level in the horizontal position of the level indicator. 
     
     
         11 . A bulls-eye level indicator for use in indicating the level of the surface as claimed in  claim 1 , wherein the said bull-eye level indicator is capable of measuring both edge and surface inclinations.
