Abstract

An accessory includes a blade, a coupling, and a guide. The blade includes a cutting edge. The coupling includes a first portion and a second portion. The first portion is attachable to and detachable from the power tool. The second portion is connected to the blade. The guide is structured to guide the blade along a work piece by interacting with a surface of the work piece as the blade moves in an advancing direction. The guide is structured to provide a locked state and an unlocked state. In the locked state, the guide is engaged with the coupling such that the guide is attached to the coupling. In the unlocked state, the guide is disengaged from the coupling such that the guide is detached from the coupling.

First claim

What is claimed is:

1 . An accessory for a power tool, the accessory comprising:
a blade with a cutting edge; a coupling including a first portion that is attachable to and detachable from the power tool and a second portion that is connected to the blade; and a guide that is structured to guide the blade along a work piece by interacting with a surface of the work piece as the blade moves in an advancing direction, the guide being structured to provide (a) a locked state in which the guide is engaged with the coupling such that the guide is attached to the coupling and (b) an unlocked state in which the guide is disengaged from the coupling such that the guide is detached from the coupling.

2 . The accessory of claim 1 , wherein:
the guide includes a guide surface; and the guide surface and the cutting edge are disposed at an acute angle relative to each other.

3 . The accessory of claim 1 , wherein:
the guide is engaged with the blade when in the locked state; and the guide is disengaged from the blade when in the unlocked state.

4 . The accessory of claim 3 , wherein:
the guide includes a first part and a second part; the first part is configured to engage with the second part to provide a locked state with respect to the coupling and the blade; and the first part is configured to disengage from the second part to provide an unlocked state with respect to the coupling and the blade.

5 . The accessory of claim 4 , wherein:
the blade includes a first opening; the coupling includes a second opening; and the first part and the second part are configured to connect to each other through the first opening and the second opening.

6 . The accessory of claim 5 , wherein:
the first part is configured to reside on a first side of the blade, the second part is configured to reside on a second side of the blade, and the guide surface extends along a plane that is perpendicular or substantially perpendicular to a surface on the first side of the blade.

7 . The accessory of claim 6 , wherein:
the first part is in contact with the coupling; and the second part is in contact with the blade.

8 . The accessory of claim 1 , wherein:
a cross-section of the guide has a shape with a plurality of sides; the cross-section of the guide has a longest side amongst the plurality of sides; and the guide surface extends from the longest side of the cross-section of the guide.

9 . The accessory of claim 1 , wherein:
the coupling includes
the first portion that extends along a first plane,
the second portion that extends along a second plane, and
a transition portion that extends between the first portion and the second portion; and
the guide surface extends between the first plane and the second plane.

10 . A power tool comprising:
a motor; and an accessory drivable by the motor, the accessory including:
a blade with a cutting edge;
a coupling including a first portion that is attachable to and detachable from the power tool and a second portion that is connected to the blade; and
a guide that is structured to guide the blade along a work piece by interacting with a surface of the work piece as the blade moves in an advancing direction, the guide being structured to provide (a) a locked state in which the guide is engaged with the coupling such that the guide is attached to the coupling and (b) an unlocked state in which the guide is disengaged from the coupling such that the guide is detached from the coupling.

11 . The power tool of claim 10 , wherein:
the guide includes a guide surface; and the guide surface and the cutting edge are disposed at an acute angle relative to each other.

12 . The power tool of claim 10 , wherein:
the guide is engaged with the blade when in the locked state; the guide is disengaged from the blade when in the unlocked state.

13 . The power tool of claim 10 , wherein:
the guide includes a first part and a second part; the first part is configured to engage with the second part to provide a locked state with respect to the coupling and the blade; and the first part is configured to disengage from the second part to provide an unlocked state with respect to the coupling and the blade.

14 . The power tool of claim 13 , wherein:
the blade includes a first opening; the coupling includes a second opening; and the first part and the second part are configured to connect to each other through the first opening and the second opening.

15 . The power tool of claim 14 , wherein:
the first part is configured to reside on a first side of the blade, the second part is configured to reside on a second side of the blade, and the guide surface extends along a plane that is perpendicular or substantially perpendicular to a surface on the first side of the blade.

16 . The power tool of claim 15 , wherein:
the first part is in contact with the coupling; and the second part is in contact with the blade.

17 . The power tool of claim 10 , wherein:
a cross-section of the guide has a shape with a plurality of sides; the cross-section of the guide has a longest side amongst the plurality of sides; and the guide surface extends from the longest side of the cross-section of the guide.

18 . The power tool of claim 10 , wherein:
the coupling includes
the first portion that extends along a first plane,
the second portion that extends along a second plane, and
a transition portion that extends between the first portion and the second portion; and
the guide surface extends between the first plane and the second plane.
