Abstract

A door hardware locating tool includes a first side wall having a first side, a second side opposite, and a cavity defined between the first and second sides. The door hardware locating tool further includes a second side wall coupled to the first side wall and extending substantially parallel to the first side wall, a center wall disposed between the first and second side walls, a clamping mechanism operable to clamp a door between the first and second side walls, and an insert at least partially located within the cavity and translatable along the first side wall between a first position and a second position. The insert includes an aperture sized to receive a cutting tool. In the first position, the aperture is located a first backset distance from the center wall, and in the second position, the third aperture is located a second backset distance from the center wall.

First claim

What is claimed is:

1. A door hardware locating tool comprising:
a first side wall including
a first side having a first aperture,
a second side opposite the first side, the second side having a second aperture, and
a cavity defined between the first and second sides;

a second side wall coupled to the first side wall and extending substantially parallel to the first side wall;
a center wall disposed between the first and second side walls;
a clamping mechanism operable to clamp a door between the first side wall and the second side wall; and
an insert at least partially located within the cavity and translatable along the first side wall between a first position and a second position, the insert including a third aperture sized to receive a cutting tool,
wherein in the first position the third aperture is located a first backset distance from the center wall and the first aperture, the second aperture, and the third aperture are aligned to provide a pathway for the cutting tool through the first side wall, and
wherein in the second position the third aperture is located a second backset distance from the center wall and the first aperture, the second aperture, and the third aperture are aligned to provide a pathway for the cutting tool through the first side wall.

2. The door hardware locating tool of claim 1 , wherein the first side wall includes a bottom side and at least one slot extending from the cavity and through the bottom side to permit egress of sawdust or other debris from the cavity.

3. The door hardware locating tool of claim 1 , wherein the insert includes a bottom side and at least one slot extending from the third aperture and through the bottom side to permit egress of sawdust or other debris from the third aperture.

4. The door hardware locating tool of claim 1 , further comprising an actuator coupled to the insert to facilitate sliding the insert between the first position and the second position.

5. The door hardware locating tool of claim 4 , wherein the actuator is snap-fit to the insert.

6. The door hardware locating tool of claim 5 , wherein the first side wall further includes a first recess and a second recess spaced from the first recess.

7. The door hardware locating tool of claim 6 , wherein the actuator includes a resilient member having a projecting portion configured to selectively engage the first recess when the insert is in the first position and the second recess when the insert is in the second position.

8. The door hardware locating tool of claim 7 , wherein the resilient member is a leaf spring.

9. The door hardware locating tool of claim 1 , wherein the clamping mechanism includes
a first rod,
a second rod spaced from the first rod,
a first bushing threadably engaged with the first rod and supported within the first side wall,
a second bushing threadably engaged with the first rod and supported within the second side wall, and
a knob coupled to the first rod to facilitate rotation of the first rod.

10. The door hardware locating tool of claim 9 , wherein the first bushing and the second bushing include internal threads of equal pitch and opposite orientation.

11. The door hardware locating tool of claim 9 , wherein a distance separating the first side wall and the second side wall increases when the first rod is rotated in a first direction relative to the first and second bushings, and wherein the distance separating the first side wall and the second side wall decreases when the first rod is rotated in a second, opposite direction relative to the first and second bushings.

12. The door hardware locating tool of claim 11 , wherein the center wall remains centered between the first and second side walls when the first rod is rotated relative to the first and second bushings.

13. The door hardware locating tool of claim 9 , wherein the first rod and the second rod extend through the center wall.

14. The door hardware locating tool of claim 9 , wherein the first rod and the second rod each contain a groove that receives a snap ring to axially fix the first rod and the second rod within the center wall.

15. The door hardware locating tool of claim 1 , wherein the center wall has a fourth aperture that is circular in shape.

16. The door hardware locating tool of claim 1 , wherein the first aperture is oblong in shape.

17. The door hardware locating tool of claim 1 , wherein the second aperture is at least the same size or larger than the first aperture and generally rectangular in shape.

18. The door hardware locating tool of claim 1 , wherein the first backset distance is 2⅜ inches.

19. The door hardware locating tool of claim 1 , wherein the second backset distance is 2¾ inches.

20. The door hardware locating tool of claim 1 , wherein the first side wall, the second side wall, the center wall, and the insert are made of plastic.
