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.

First claim

What is claimed is:

1. 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.

2. The framing square of claim 1 , wherein the first distance is greater than 6 inches and the second distance is between ½ inches and 2 inches.

3. The framing square of claim 1 , further comprising a border surrounding the array of marking openings.

4. The framing square of claim 1 , wherein the blade section, the tongue section, and the corner section comprise an integral and continuous piece of a metal material and wherein the pivot opening is collinear with all of the array of marking openings along a midline of a longitudinal axis of the blade section.

5. The framing square of claim 4 , wherein a ratio of the first distance to the second distance, such that ratio is defined as the first distance divided by the second distance, is between 0.2 and 5.

6. The framing square of claim 5 , further comprising:
an inner longitudinal edge extending along the blade section;
an outer longitudinal edge extending along the blade section, the inner longitudinal edge being parallel and opposite to the outer longitudinal edge along the blade section;
an inner transverse edge extending along the tongue section; and
an outer transverse edge extending along the tongue section, wherein the pivot opening is formed through a boundary between the corner section and the blade section such that the pivot is collinear with the inner transverse edge of the tongue section.

7. The framing square of claim 1 , wherein the array of marking openings comprises five marking openings, the marking openings corresponding to an arc measured between the pivot opening and the five marking openings, the distance from the pivot opening to a first marking opening being between 13 inches and 15 inches, a second marking opening being between 14 inches and 16 inches, a third marking opening being between 15 inches and 17 inches, a fourth marking opening being between 16 inches and 18 inches, and a fifth marking opening being between 17 inches and 19 inches.

8. 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.

9. The framing square of claim 8 , wherein a width of the blade measured perpendicular to the longitudinal axis is greater than a width of the tongue measured perpendicular to the transverse axis.

10. The framing square of claim 8 , wherein the tongue and the blade form a rectangular shaped section such that the tongue intersects the blade at a 90° angle at the corner section and the blade is longer than the tongue.

11. The framing square of claim 8 , wherein the blade, the tongue, and the corner section comprise an integral and continuous piece of material.

12. The framing square of claim 8 , wherein the pivot opening and the at least two marking openings are collinear with each other.

13. The framing square of claim 12 , wherein a central longitudinal axis of the blade intersects the pivot opening and the at least two marking openings.

14. The framing square of claim 8 , further comprising a distal solid region of the blade coupled to the marking region and extending along the longitudinal axis of the blade, wherein a first side of the marking region couples to a proximal solid region of the blade that is coupled to the corner section, and a second side of the marking region, opposite the first side, is coupled to the distal solid region of the blade further extending along the longitudinal axis.

15. The framing square of claim 14 , wherein a ratio of a length of the marking region to a length of the proximal solid region along the longitudinal axis of the blade is between 2 and 5, and the ratio of a length of the distal solid region to the length of the proximal solid region is between 3 and 4, and wherein the length of the proximal solid region is greater than 6 inches and equal to a length of the tongue extending along a transverse axis that is perpendicular to the longitudinal axis.

16. The framing square of claim 8 , wherein a diameter of the pivot opening is between 1/16 inch and ¾ inch, wherein diameters of each of the marking openings are between ⅛ inch and ⅝ inch, and the length of the solid region is greater than 6 inches, wherein the distance between the center of a first marking region opening and the center of a second marking region opening is between ½ inch and 2 inches.

17. The framing square of claim 8 , further comprising more than 4 and less than 10 marking openings.

18. 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.

19. The method of claim 18 , further comprising forming a cut through the workpiece, wherein the marking utensil comprises a blade.
