Abstract
A framing square including an integrated protractor feature is provided. The framing square includes a blade section, and a tongue section joined at a corner section. The corner section further includes a pivot opening, to rotatably couple the framing square to a workpiece. The blade section includes an array of marking openings. The marking openings are spaced from each other in the array, and the array is positioned a first distance from the pivot opening along a longitudinal axis of the blade. The marking openings can be sized to receive a particular marking instrument (e.g., a pencil or knife) for use with a particular framing square.
Claims19
A framing square, comprising:
- a blade section;
- a tongue section;
- a corner section interconnecting the blade section and the tongue section such that the blade section is coupled to the tongue section at a right angle, the blade section, the corner section and the tongue section together forming an L-shape;
- a pivot opening defined within the corner section;
- an opening formed through the tongue section, the opening located along a midline of a transverse axis of the tongue section;
- and
- an array of marking openings formed through the blade section, the array of marking openings being located a first distance from the pivot opening, the array of marking openings comprises at least two openings spaced from each other by a second distance, wherein the first distance is greater than the second distance.
A framing square, comprising:
- a blade extending in a first direction along a longitudinal axis, the blade comprising:
- a solid region extending a length along the longitudinal axis of the blade;
- and
- a marking region coupled to the solid region of the blade and extending along the longitudinal axis of the blade;
- a tongue extending in a second direction along a transverse axis perpendicular to the blade, the tongue comprising a solid region extending a length along the transverse axis of the tongue;
- a corner section coupling the solid region of the blade to the solid region of the tongue, the corner, the blade and the tongue together forming an L-shape;
- a pivot opening defined within the corner section;
- and
- two or more marking openings formed in the blade, the marking openings comprising a distance between a center of a first marking opening and a center of a last marking opening is less than a length of the solid region of the blade along the longitudinal axis
- an opening formed through the tongue, the opening located along a midline of the transverse axis of the tongue.
A method of forming an arc-shaped marking using a framing square, the method comprising:
- positioning a framing square in contact with a surface of a workpiece;
- positioning a pivot through a pivot opening defined within the framing square;
- positioning a marking utensil through a marking opening formed through the framing square, wherein the marking opening is located a first distance extending in a first direction from the pivot, wherein the first distance is equal to a second distance extending from the pivot to an outer edge of the framing square in a second direction, the second direction perpendicular to the first direction;
- rotating the framing square and marking utensil about the pivot, such that an arc-shaped mark is formed by the marking utensil on the surface of the workpiece, wherein a radius of the arc-shaped mark corresponds to the first distance;
- and
- using the framing square to view an intersection of the arc-shaped mark generated at a 90° radius.
