Abstract

A power tool constructed in accordance to one example of the present disclosure can include a repositionable tool accessory. The repositionable tool accessory can be selectively coupled to a first mounting structure on the tool. The repositionable tool accessory can include a tool accessory housing, a rod, a roller, and a locking knob. The tool accessory housing can define a first rod opening and include engaging structure that is configured to cooperatively mate with the first mounting structure. The rod can slidably translate along the first rod opening. The roller can be rotatably coupled to a distal portion of the rod. The locking knob can be movable between an unlocked position wherein the rod is freely translatable along the first rod opening to locate the roller at different locations relative to the output member, and a lock position wherein the rod is fixed relative to the tool accessory housing.

Claims

1. A power tool comprising:

a tool housing;

a motor disposed in the tool housing and that drives an output member;

a first mounting structure arranged on the tool housing; and

a repositionable tool accessory selectively coupled to the first mounting structure, the repositionable tool accessory comprising;

a tool accessory housing defining a first rod opening and having engaging structure configured to cooperatively mate with the first mounting structure to couple the tool accessory housing to the tool housing;

a rod having a proximal portion, an intermediate portion and a distal portion, the proximal portion of the rod received in and slidably translatable along the first rod opening of the tool accessory housing;

a roller rotatably coupled to the distal portion of the rod; and

a locking member coupled to the tool accessory housing and movable between an unlocked position wherein the rod is freely translatable along the first rod opening to locate the roller at different locations relative to the output member and a locked position wherein the rod is fixed relative to the tool accessory housing;

wherein the distal portion of the rod extends along a distal axis, and the proximal portion of the rod extends along a proximal axis, wherein the distal and proximal axes are non-interesting and substantially transverse.

2. The power tool of claim 1 wherein the tool accessory housing further defines a second rod opening, distinct from the first rod opening and configured to selectively and alternatively receive the proximal portion of the rod.

3. The power tool of claim 1 wherein one of the first mounting structure and the engaging structure comprises at least one inset and the other of the first mounting structure and the engaging structure comprises at least one outset, wherein the at least one outset is configured to non-rotatably nest within the at least one inset.

4. The power tool of claim 3 wherein the at least one inset comprises three insets and the at least one outset comprises three outsets.

5. The power tool of claim 4 wherein the insets and outsets have a rectangular geometry.

6. The power tool of claim 3, further comprising a fastener that extends through the at least one inset and outset and threadably engages the mounting structure to fix the tool accessory housing to the tool housing.

7. The power tool of claim 1 wherein the intermediate portion extends along an intermediate axis that intersects with and is substantially transverse relative to the proximal axis.

8. The power tool of claim 1 wherein the rod has a flat formed at the proximal portion, wherein the locking member comprises a locking knob that selectively engages the flat.

9. The power tool of claim 1, further comprising a second mounting structure arranged on an opposite side of the tool housing relative to the first mounting structure, the second mounting structure configured to selectively couple with the engaging structure of said repositionable tool accessory.

18. The power tool of claim 1 wherein the first rod opening extends along a first axis and the second rod opening extends along a second axis, and further wherein the first and second axes are non-parallel and intersecting.

19. The power tool of claim 18 wherein the first and second axes intersect in the tool accessory housing where the locking member is coupled to the tool accessory housing so that the locking member in its locked position can fix the position of the rod relative to the tool accessory housing when the proximal portion of the rod is received in either of said first or second rod openings.

10. A repositionable tool accessory configured for a power tool, the repositionable tool accessory comprising:

a tool accessory housing defining a first rod opening and having engaging structure configured to cooperatively mate with a mounting structure on the power tool to couple the tool accessory housing to the power tool;

a rod having a proximal portion, an intermediate portion and a distal portion, the proximal portion of the rod received in and slidably translatable along the first rod opening of the tool accessory housing;

a roller rotatably coupled to the distal portion of the rod; and

a locking member coupled to the tool accessory housing and movable between an unlocked position wherein the rod is freely translatable along the first rod opening to locate the roller at different locations relative to the power tool and a locked position wherein the rod is fixed relative to the tool accessory housing;

wherein the tool accessory housing further defines a second rod opening, distinct from the first rod opening, and configured to selectively and alternatively receive the proximal portion of the rod.

11. The repositionable tool accessory of claim 10 wherein one of the first mounting structure and the engaging structure comprises at least one inset and the other of the first mounting structure and the engaging structure comprises at least one outset, wherein the at least one outset is configured to non-rotatably nest within the at least one inset.

12. The repositionable tool accessory of claim 11 wherein the at least one inset comprises three insets and the at least one outset comprises three outsets.

13. The repositionable tool accessory of claim 12 wherein the insets and outsets have a rectangular geometry.

14. The repositionable tool accessory of claim 11, further comprising a fastener that extends through the at least one inset and outset and threadably engages the mounting structure to fix the tool accessory housing to the tool housing.

15. The repositionable tool accessory of claim 10 wherein the distal portion of the rod extends along a distal axis, and the proximal portion of the rod extends along a proximal axis, wherein the distal and proximal axes are non-intersecting and substantially transverse.

16. The repositionable tool accessory of claim 15 wherein the intermediate portion extends along an intermediate axis that intersects with and is substantially transverse relative to the proximal axis.

17. The repositionable tool accessory of claim 10 wherein the rod has a flat formed at the proximal portion, wherein the locking member comprises a locking knob that selectively engages the flat.

20. The repositional tool accessory of claim 10 wherein the first rod opening extends along a first axis and the second rod opening extends along a second axis, and further wherein the first and second axes are non-parallel and intersecting.

21. The repositional tool accessory of claim 20 wherein the first and second axes intersect in the tool accessory housing where the locking member is coupled to the tool accessory housing so that the locking member in its locked position can fix the position of the rod relative to the tool accessory housing when the proximal portion of the rod is received in either of said first or second rod openings.

22. The repositional tool accessory of claim 10 wherein the locking member comprises a knob coupled to a threaded axle threadably received in the tool accessory housing, and further wherein the threaded axle engages the proximal portion of the rod in the locked position.
