Abstract
In the embodiments herein, an instrument for level and plumb determinations, includes: a sealed chamber of equal dimensions made from transparent or translucent material marked with center lines and filled with a colored fluid, so when placed on any surface. Relative to the orientation of the surface to the face of the earth, the instrument reveals if a surface is: plumb within an upright position; level within a horizontal position; or at an angle, which can be marked and transferred. Reference lines are placed exactly parallel and centered to the sides and ends.
Claims18
An instrument for level and plumb determinations, comprising:
- a sealed chamber made from transparent or translucent material marked with sets of center lines and filled with a fluid, such that when placed on any surface, the orientation of the surface to the face of the earth is either plumb, if the instrument is held in an upright direction;
- or level if the instrument held in a horizontal direction;
- and
- reference lines, which are placed exactly parallel and centered to the sides and ends of the sealed chamber;
- wherein the fluid is configured to seek its own level, wherein the fluid is present in the sealed chamber at a range of between 48%-52% of a capacity of the sealed chamber, wherein the fluid in the sealed chamber is at a level that:
- (i) corresponds exactly to a level of a horizontal line of the references lines, while (ii) bisecting a vertical line of the reference lines, and (iii) bisecting two sets of the sets of center lines, when the instrument is placed on a surface that is level, wherein said two sets of the sets of center lines are opposite to each other along the horizontal line and bisected by the horizontal line.

An instrument for angle determination in degrees, comprising:
- a sealed chamber made from transparent or translucent material marked with a protractor and filled with a fluid, such that when placed on any surface, the angle determination is achieved;
- and
- reference lines that traverse the protractor;
- wherein the fluid is configured to seek its own level, wherein the fluid in the sealed chamber is present at 48%-52% capacity of the sealed chamber, wherein the fluid in the sealed chamber is at a level that (i) corresponds exactly to a level of a horizontal line of the references lines, while (ii) bisecting a vertical line of the reference lines, and (iii) bisecting the protractor.
1 more element
A method for determining an orientation via an instrument, wherein the method comprises:
- placing the instrument on a first surface, thereby modifying or not modifying a fluid level of the instrument;
- marking the fluid level at two points;
- wherein the orientation is a level, a plumb, or an angle;
- and
- wherein the instrument comprises:
- (1) sealed chamber having a rectangular perimeter a made from:
- (a) transparent or translucent material marked and filled with a fluid, and marked with reference lines, and respective sets of center lines, and (b) spacers that ensure the fluid is only affected by gravity, such that when placed on any surface, the orientation of the surface to the face of the earth is either plumb, if the instrument is held in an upright direction, or level, if the instrument is held in a horizontal direction;
- wherein the reference lines are placed exactly parallel and centered to the sides and ends of the sealed chamber having the rectangular perimeter;
- wherein each set of the respective sets of center lines is placed proximal to a top-most side, a bottom-most side, a right-most side, or a left-most side, such that each set of the respective sets of center lines proximal to the top-most, the bottom-most, the right-most, and the left-most sides make a polygonal perimeter, to aid in ease of viewing of the fluid level, when determining if the orientation is plumb or level;
- wherein the fluid is present in a range of 48-52% capacity of the sealed chamber having the rectangular perimeter, wherein the fluid level in the sealed chamber having the rectangular perimeter, (i) corresponds exactly to a level of a horizontal line of the references lines, while (ii) bisecting a vertical line of the reference lines and (iii) bisecting two sets of the respective sets of center lines, when the instrument is placed on a surface that is level, wherein said two sets of the sets of center lines are opposite to each other along the horizontal line and bisected by the horizontal line;
- or
- (2) a sealed chamber having a square perimeter, wherein the sealed chamber having the square perimeter is made from:
- (a) transparent or translucent material marked and filled with a fluid, and marked a protractor comprising a plurality of concentric circles, and (b) spacers that ensure the fluid is only affected by gravity, such that when placed on any surface, the angle determination is achieved;
- and
- wherein reference lines that traverse the plurality of concentric circles;
- wherein the fluid is present in a range of 48-52% capacity of the sealed chamber having the rectangular perimeter, such that the fluid level in the sealed chamber having the rectangular perimeter, (i) corresponds exactly to a level of a horizontal line of the references lines, while (ii) bisecting a vertical line of the reference lines, when the instrument is placed on a surface that is level.
