Abstract
A carpenter square including a triangular plate and a base. The base has a corner at an intersection of a first side and first end. The corner extends into a pivot notch defined in a first side edge of the plate. During use, the base's corner may be placed on a side wall of a workpiece and the plate is pivoted about a pivot axis extending along the base's corner. An angular measurement may be marked on the workpiece's surface when a selected angle on the plate aligns with an edge of the workpiece that extends along an intersection of the workpiece's surface and side wall. First and second regions of the plate extend outwardly beyond opposite ends of the base. Each of the first and second regions includes a distance measurement scale and the first region further includes one or more angular measurement scales.
Claims21
A carpenter square comprising:
- a plate which is triangular in shape, wherein the plate includes a first side edge and a second side edge arranged at a right angle to one another, and a hypotenuse located opposite the right angle;
- and
- a base operatively engaged with the plate and being arranged generally parallel to the second side edge of the plate;
- wherein the base has a first side and a first end that intersect at a corner;
- wherein the plate defines a pivot notch in the first side edge;
- wherein the corner extends over the pivot notch when the base is engaged with the plate;
- and
- wherein the first side and the first end of the base are oriented at an angle of less than 90° to one another.
A carpenter square comprising:
- a plate which is triangular in shape, wherein the plate includes a first side edge and a second side edge arranged at a right angle to one another, and a hypotenuse located opposite the right angle;
- and
- a base operatively engaged with plate;
- wherein the base has a first side, a first end, and a second end opposed to the first end, wherein the first side and the first end intersect at a corner and are oriented at an angle of less than 90° to one another;
- wherein one or both of the first end and the second end is parallel to the second side edge of the plate;
- and
- wherein a first region of the plate extends outwardly beyond the first end of the base in a first direction, and a second region of the plate extends outwardly beyond the second end of the base in a second direction.
A method of marking a measurement on a workpiece comprising:
- providing a carpenter square comprising a plate which is triangular and has a first side edge, a second side edge arranged at a right angle to the first side edge, and a hypotenuse located opposite the right angle;
- and a base engaged with the triangular plate, wherein the base has a first side, a first end, and a second end opposed to the first end, wherein the first side and the first end intersect at a corner and are oriented at an angle of less than 90° to one another;
- wherein one or both of the first end and the second end is parallel to the second side edge of the plate;
- and wherein a first region of the plate extends outwardly beyond the first end of the base in a first direction, and a second region of the plate extends outwardly beyond the second end of the base in a second direction;
- providing a first measurement scale on the first region of the plate;
- providing a second measurement scale on the second region of the plate;
- using the carpenter square with the plate in a first orientation to measure one of a distance and an angle with the first measurement scale;
- using the carpenter square with the plate in a second orientation to measure a distance with the second measurement scale.
