## Abstract

A power tool includes a motor, a foot plate, a detent system, and an accessory. The motor is configured to move a saw blade in a repeating pattern of movement. The foot plate defines a saw blade opening and includes a guide surface that defines a storage space. The detent system is supported by the foot plate and has a detent member. The accessory defines (i) a first detent structure configured to receive the detent member therein, and (ii) a second detent structure configured to receive the detent member therein. The accessory is positionable between (i) a use position in which the accessory is spaced apart from the foot plate, and (ii) a storage position in which the accessory is located in the storage space.

## Claims

### Claim 1

A power tool, comprising:
a motor configured to move a saw blade in a repeating pattern of movement;
a foot plate defining a saw blade opening, said foot plate having a guide surface that defines a storage space;
a detent system supported by said foot plate and having a detent member; and
an accessory defining (i) a first detent structure configured to receive said detent member therein, and (ii) a second detent structure configured to receive said detent member therein,
wherein said accessory is positionable between (i) a use position in which said accessory is spaced apart from said foot plate, and (ii) a storage position in which said accessory is located in said storage space,
wherein, during movement of said accessory from said use position to said storage position, said detent member is advanced (i) into said first detent structure, (ii) out of said first detent structure, and then (iii) into said second detent structure, and
wherein, during movement of said accessory from said storage position to said use position, said detent member is advanced (i) out of said second detent structure, (ii) into said first detent structure, and then (ii) out of said first detent structure.

### Claim 2 (depends on 1)

The power tool of claim 1, wherein:
said guide surface includes a plurality of walls that defines said storage space,
said plurality of walls includes a first lateral wall and a second lateral wall, and
said accessory is interposed between said first lateral wall and said second lateral wall when said accessory is located in said storage position.

### Claim 3 (depends on 1)

The power tool of claim 1, wherein said detent member is located in said second detent structure when said accessory is located in said storage position.

### Claim 4 (depends on 1)

The power tool of claim 1, wherein:
said detent member is movable between a first detent position and a second detent position, and
movement of said accessory from said use position to said storage position causes said detent member to move from said first detent position to said second detent position.

### Claim 5 (depends on 4)

The power tool of claim 4, wherein said accessory is advanced into contact with said detent member when said accessory is advanced from said use position to said storage position.

### Claim 6 (depends on 1)

The power tool of claim 1, wherein:
said accessory includes a plate having a top plate surface, a bottom plate surface, a first lateral side interposed between said top plate surface and said bottom plate surface, and a second lateral side interposed between said top plate surface and said bottom plate surface, and
one of said first lateral side and said second lateral side defines one of said first detent structure and said second detent structure.

### Claim 7 (depends on 6)

The power tool of claim 6, wherein:
said first lateral side surface includes an intermediate side surface interposed between said first detent structure and said second detent structure,
during movement of said accessory from said use position to said storage position, said detent member is advanced into contact with said intermediate side surface after said detent member is advanced out of said first detent structure and before said detent member is advanced into said second detent structure, and
during movement of said accessory from said storage position to said use position, said detent member is advanced into contact with said intermediate side surface after said detent member is advanced out of said second detent structure and before said detent member is advanced into said first detent structure.

wherein said first lateral side defines a first detent structure and a second detent structure that are linearly aligned with one another, and
wherein said accessory includes a wrench structure that has at least a first polygonal drive surface that extends between said top surface and said bottom surface.

### Claim 16 (depends on 15)

The accessory of claim 15, further comprising:
a screwdriver structure that has a linear drive surface.

### Claim 17 (depends on 16)
