Abstract
A tool for changing a substantially level or unlevel floor to a sloped floor having a predetermined slope includes a float stick formed of a rigid, cuttable material so that it can be cut to length as required by the size of the floor. The float stick has a sloped top edge and a flat bottom edge. The sloped top edge slopes downwardly from a proximal end to a distal end of the float stick at a predetermined slope per linear unit. A spirit level is mounted to the float stick and is calibrated so that its bubble is centered when the flat bottom edge is level. At least one vertical bore is formed in the float stick and an adjustment peg is disposed within the bore. The adjustment peg is extended from the bore to level the flat bottom edge of the float stick on an uneven floor.
Claims4
A tool for changing an unlevel floor to a sloped floor having a predetermined slope, comprising:
- a float stick of elongate configuration having a proximal end and a distal end;
- said float stick formed of a rigid, cuttable material so that it can be cut to length as may be required by the size of the floor;
- said float stick having a sloped top edge surface and a flat bottom edge surface, said sloped top edge surface sloping downwardly relative to said flat bottom edge surface from said proximal end to said distal end at a predetermined slope per linear unit;
- a recess formed in said sloped top edge surface;
- a spirit level positioned in said recess and calibrated so that a bubble of said spirit level is centered when said flat bottom edge surface is substantially level;
- at least one bore formed in said float stick, said bore extending from said sloped top edge surface to said flat bottom edge surface;
- an adjustment peg disposed within said at least one bore, said adjustment peg having a length that exceeds a length of said at least one bore and said adjustment peg being formed of a cuttable material;
- said adjustment peg having a retracted position where a leading end of said adjustment peg is flush with said flat bottom edge surface;
- and
- said adjustment peg having at least one extended position where said leading end of said adjustment peg extends below said flat bottom edge surface when said float stick is supported by said unlevel floor, and said adjustment peg being extended by a distance required to make said flat bottom edge surface level as indicated by said spirit level.
