Abstract

A reciprocating power tool including a housing supporting a motor having a drive shaft, a blade clamp mechanism, and a drive mechanism. The drive clamp mechanism is coupled to the motor for converting rotational motion of the drive shaft into reciprocating motion of the blade clamp mechanism. The power tool includes an accessory having an attachment portion coupled to the blade clamp mechanism, and a body portion extending from the attachment portion. A grout rake is coupled to the body portion and includes a plurality of cutter portions. The grout rake is repositionable relative to the body portion between a first position and a second position. In the first position one of the plurality of cutter portions is located in a working position for contacting a workpiece, and in the second position another one of the plurality of cutter portions is located in the working position for contacting the workpiece.

First claim

What is claimed is:

1. A reciprocating power tool comprising:
a housing supporting a motor having a drive shaft, the motor actuatable by a trigger;
a blade clamp mechanism;
a drive mechanism coupled to the motor for converting rotational motion of the drive shaft into reciprocating motion of the blade clamp mechanism; and
an accessory including:
an attachment portion configured to be coupled to the blade clamp mechanism;
a body portion extending from the attachment portion;
a grout rake movably coupled to the body portion at a hub, the grout rake including a plurality of cutter portions extending from the hub in different directions;

wherein the grout rake is repositionable relative to the body portion at the hub between a first position and a second position, wherein in the first position one of the plurality of cutter portions is located in a working position for contacting a workpiece, and wherein in the second position another one of the plurality of cutter portions is located in the working position for contacting the workpiece.

2. The reciprocating power tool of claim 1 , wherein at least two of the plurality of cutter portions includes a unique cutting width.

3. The reciprocating power tool of claim 2 , wherein the grout rake includes an aperture for receiving a fastener, and wherein at least two of the plurality of cutter portions extend along a unique axis, each unique axis extending away from the aperture.

4. The reciprocating power tool of claim 1 , wherein at least two of the plurality of cutter portions extend along a unique axis, each unique axis extending radially from a point.

5. The reciprocating power tool of claim 1 , further comprising a first aperture in the grout rake and a second aperture in the body portion, the first and second apertures for receiving a fastener for removably securing the grout rake to the body portion.

6. The reciprocating power tool of claim 1 , further comprising a fastener extending through a first aperture in the grout rake and a second aperture in the body portion for removably securing the grout rake to the body portion.

7. The reciprocating power tool of claim 1 , wherein the plurality of cutter portions include:
a first cutter portion including a substantially rounded tip, the first cutter portion extending from a point along a first axis; and
a second cutter portion including a substantially rectangular-shaped tip having a width, the second cutter portion extending from the point along a second axis.

8. The reciprocating power tool of claim 7 , wherein the width is a first width, and wherein the plurality of cutter portions further include:
a third cutter portion including a substantially rectangular-shaped tip having a second width, the third cutter portion extending from the point along a third axis, the second width being different from the first width.

9. The reciprocating power tool of claim 8 , wherein a first angle is defined between the first axis and the second axis, a second angle is defined between the second axis and the third axis, and a third angle is defined between the third axis and the first axis.

10. The reciprocating power tool of claim 9 , wherein the first angle is about 120 degrees, the second angle is about 90 degrees, and the third angle is about 150 degrees.

11. The reciprocating power tool of claim 9 , wherein the first, second, and third angles are substantially different.

12. The reciprocating power tool of claim 1 , wherein the hub includes an aperture therethrough, the grout rake being repositionable by rotation about a center of the aperture between the first position and the second position.

13. The reciprocating power tool of claim 1 , wherein the grout rake is repositionable by rotation between the first position and the second position.

14. The reciprocating power tool of claim 1 , wherein the grout rake includes at least three cutter portions.

15. An accessory for use with a reciprocating power tool, the accessory comprising:
an attachment portion;
a body portion extending from the attachment portion; and
a grout rake movably coupled to the body portion at a hub, the grout rake including a plurality of cutter portions extending from the hub in different directions;
wherein the grout rake is repositionable relative to the body portion at the hub between a first position and a second position, wherein in the first position one of the plurality of cutter portions is located in a working position for contacting a workpiece, and wherein in the second position another one of the plurality of cutter portions is located in the working position for contacting the workpiece.

16. The accessory of claim 15 , wherein at least two of the plurality of cutter portions includes a unique cutting width.

17. The reciprocating power tool of claim 15 , wherein the grout rake includes an aperture for receiving a fastener, and wherein at least two of the plurality of cutter portions extend along a unique axis, each unique axis extending away from the aperture.

18. The reciprocating power tool of claim 17 , wherein the grout rake is repositionable by rotation about a center of the aperture between the first position and the second position.

19. The reciprocating power tool of claim 15 , wherein the grout rake is repositionable by rotation between the first position and the second position.

20. The accessory of claim 15 , wherein at least two of the plurality of cutter portions extend along a unique axis, each unique axis extending radially from a point.

21. The accessory of claim 15 , further comprising a first aperture in the grout rake and a second aperture in the body portion, the first and second apertures for receiving a fastener for removably securing the grout rake to the body portion.

22. The accessory of claim 15 , wherein the grout rake includes at least three cutter portions.

23. The accessory of claim 15 , wherein the plurality of cutter portions include:
a first cutter portion including a substantially rounded tip, the first cutter portion extending from a point along a first axis; and
a second cutter portion including a substantially rectangular-shaped tip having a width, the second cutter portion extending from the point along a second axis.

24. The accessory of claim 23 , wherein the width is a first width, wherein the plurality of cutter portions further include:
a third cutter portion including a substantially rectangular-shaped tip having a second width, the third cutter portion extending from the point along a third axis, the second width being different from the first width.

25. The accessory of claim 24 , wherein a first angle is defined between the first axis and the second axis, a second angle is defined between the second axis and the third axis, and a third angle is defined between the third axis and the first axis.

26. The accessory of claim 25 , wherein the first angle is about 120 degrees, the second angle is about 90 degrees, and the third angle is about 150 degrees.
