NZ761038B2 - Hinge mortising tool - Google Patents

Abstract

mortising kit for hinges, locks, strike plates, and the like includes a guide attachable to a subject to be mortised (e.g., door or door jamb). The kit includes a chisel that interacts with locating features of the guide to ensure proper placement of the chisel. The chisel has a blade and a chisel locator. There is a slidable relationship between the guide and the chisel which maintains the blade on a path perp to and spaced from a perimeter of the guide. Separating the chisel locator and the guide locator, removes the chisel. The guide includes at least one additional locator for aligning the chisel locator to form an additional slidable relationship between the guide and chisel, to maintain the blade on additional path perpendicular to and spaced from the perimeter of the guide, the additional path such that force applied to the chisel when in the slidable relationship results in first mortise perimeter cuts and second mortise perimeter cuts that partially intersects to define a mortise perimeter. Force applied to the chisel can score or otherwise cut the subject to a desired depth, at which point stops or other features of the guide can limit the chisel from scoring or cutting deeper. Placement of the chisel at opposite ends of the guide allow the full mortise perimeter to be scored or cut. Excess waste material can be removed from between the mortise perimeter, such as through use of the block plane. A method of using the mortising kit is also included.

Claims (17)

What is claimed is:

1. A mortising kit, comprising: a chisel having a blade for cutting mortise perimeter cuts into a substrate, the chisel including a chisel locator feature; and a guide positionable on the substrate at a mortise location and having one or more edges defining a perimeter, the guide having at least one guide locator feature for interacting with the chisel locator feature to establish a slidable relationship between the guide and the chisel, wherein the slidable relationship maintains the blade of the chisel on a path perpendicular to and spaced apart from the perimeter of the guide, wherein separating the chisel locator feature and the guide locator feature removes the chisel, wherein the guide includes at least one additional locator feature for aligning the chisel locator feature to establish an additional slidable relationship between the guide and the chisel, wherein the additional slidable relationship maintains the blade of the chisel on an additional path perpendicular to and spaced apart from the perimeter of the guide, and wherein the additional path is spaced apart from the path such that force applied to the chisel when in the slidable relationship results in first mortise perimeter cuts in the substrate and force applied to the chisel when in the additional slidable relationship results in second mortise perimeter cuts in the substrate that partially intersect the first mortise perimeter cuts, and wherein the first mortise perimeter cuts and the second mortise perimeter cuts define a mortise perimeter.

2. The kit of claim 1, wherein the chisel includes a shoulder interactable with one or more end surfaces of the one or more guide locator features when in the slidable relationship to limit travel of the blade.

3. The kit of claim 1, wherein the chisel includes a shoulder, and wherein the guide includes one or more stops interactable with shoulder of the chisel to limit travel of the blade when the chisel and the guide are in the slidable relationship.

4. The kit of any one of claims 1 to 3, wherein the chisel includes a blade holder for removably securing the blade.

5. The kit of claim 4, further comprising at least one additional blade exchangeable with the blade, wherein the blade is shaped to produce mortise perimeter cuts associated with a first mortise shape, and wherein the at least one additional blade is shaped to produce mortise perimeter cuts associated with one or more additional mortise shapes that differ from the first mortise shape.

6. The kit of claim 1, wherein (i) the chisel locator feature includes a protrusion and the at least one guide locator feature includes an aperture, or (ii) the chisel locator feature includes an aperture and the at least one guide locator feature includes a protrusion, and wherein the protrusion and the aperture establish the slidable relationship.

7. A mortising kit, comprising: a chisel locator feature on a chisel having a blade and at a distance spaced apart from the blade; a guide locator feature on a guide having a perimeter and at a distance spaced apart from the perimeter, wherein the blade is confined to a path perpendicular to and spaced apart from the perimeter when the chisel locator feature interacts with the guide locator feature, and wherein separating the chisel locator feature and the guide locator feature removes the chisel; an additional guide locator feature on the guide such that the blade is aligned with an additional path perpendicular to and spaced apart from the perimeter when the chisel locator feature interacts with the additional guide locator feature, wherein force applied to the chisel results in a first mortise perimeter cut when the chisel locator feature interacts with the guide locator feature, wherein force applied to the chisel results in a second mortise perimeter cut when the chisel locator feature interacts with the additional guide locator feature, and wherein the first mortise perimeter cut and second mortise perimeter cut partially intersect to define a mortise perimeter.

8. The kit of claim 7, further comprising a shoulder positionable on the chisel and interactable with an end surface of the guide locator feature to limit travel of the blade when the chisel locator feature interacts with the guide locator feature.

9. The kit of claim 7, further comprising: a chisel shoulder positionable on the chisel; and a stop positionable on the guide and interactable with the chisel shoulder to limit travel of the blade when the chisel locator feature interacts with the guide locator feature.

10. The kit of any one of claims 7 to 9, wherein the chisel includes a blade holder for removably securing the blade.

11. The kit of claim 10, further comprising an additional blade exchangeable with the blade, wherein the blade is shaped to produce mortise perimeter cuts associated with a first mortise shape, and wherein the additional blade is shaped to produce mortise perimeter cuts associated with a second mortise shape that differs from the first mortise shape.

12. The kit of claim 7, wherein one of the chisel locator feature and the guide locator feature includes a protrusion, wherein another of the chisel locator feature and the guide locator feature includes an aperture, wherein the protrusion and the aperture establish a slidable relationship when the chisel locator feature and the guide locator feature interact.

13. A method, comprising: positioning a guide on a substrate material, the guide including a guide locator feature; aligning a chisel locator feature of a chisel with the guide locator feature of the guide; manipulating the chisel to induce interaction between the guide locator feature and the chisel locator feature and place a blade of the chisel against a surface of the substrate material; applying force to the chisel to push the blade into the substrate material and generate a mortise perimeter cut; removing the chisel by separating the chisel locator feature and the guide locator feature; aligning the chisel locator feature with an additional guide locator feature of the guide; manipulating the chisel to induce interaction between the additional guide locator feature and the chisel locator feature and place the blade of the chisel against the surface of the substrate material; and applying force to the chisel to push the blade into the substrate material and generate an additional mortise perimeter cut, wherein the mortise perimeter cut and the additional mortise perimeter cut partially intersect to define a mortise perimeter.

14. The method of claim 13, further comprising: applying block plane to remove material from the substrate material within the mortise perimeter.

15. The method of either of claim 13 or 14, wherein applying force to the chisel includes applying sufficient force to cause a shoulder of the chisel to interact with an end surface of the guide locator feature to limit travel of the blade into the substrate material.

16. The method of either of claim 13 or 14, wherein applying force to the chisel includes applying sufficient force to cause a shoulder of the chisel to interact with a stop of the guide to limit travel of the blade into the substrate material.

17. The method of claim 13, wherein aligning the chisel locator feature with the guide locator feature includes aligning a protrusion with an aperture, wherein the protrusion and the aperture establish a slidable relationship when the chisel locator feature and the guide locator feature interact.
