Abstract

A miter saw for use with a miter saw stand includes a base having a first clamping surface, a second clamping surface, and a first actuator. The miter saw further includes a turntable rotatable in relation to the base and having a work piece support surface. The miter saw also includes a support assembly attached to the turntable, and a cutting assembly attached to the support assembly and positioned over the turntable. The first actuator is movable between a first position and a second position. Movement of the first actuator from the first position towards the second position causes the first clamping surface to move toward the second clamping surface.

Claims (54)

1. A miter saw for use with a miter saw stand, comprising:

a base having a first mounting member that defines a first clamping surface and is movably attached to said base, a second mounting member that defines a second clamping surface and is attached in a fixed position to said base, and a first actuator, the first mounting member and the second mounting member being spaced apart horizontally with the first clamping surface and the second clamping surface arranged facing each other, the first actuator being configured to move the first mounting member between a clamped and an unclamped position in relation to said second clamping member to removably secure said base to a miter stand;

a turntable rotatable in relation to said base and having a work piece support surface;

a support assembly attached to said turntable; and

a cutting assembly attached to said support assembly and positioned over said turntable,

wherein said base includes an upper surface positioned above said first mounting member and a first bore structure that defines a first fastener passage that extends downwardly through said upper surface,

wherein said first actuator includes a fastener that extends through said first bore structure and is connected to said first mounting member and a handle connected to an end of the fastener and positioned above the upper surface for moving the fastener within the bore structure,

wherein said fastener of said first actuator is movable longitudinally by said handle between a first position and a second position in relation to said first bore structure,

wherein movement of said fastener of said first actuator between said first position said second position causes said first mounting member to move between said unclamped and said clamped positions, respectively,

wherein movement of said first mounting member between said clamped and said unclamped position causes said first clamping surface to move horizontally closer to and farther way from said second clamping surface, respectively,

wherein said base includes foot structures that extend below the first and second mounting members, the foot structures having bottom surfaces for supporting the base on a flat work surface, and

wherein the first mounting member, the second mounting member, and the first actuator are each located above the bottom surfaces of the foot structures in the clamped and the unclamped positions.

2. The miter saw of claim 1 , wherein said first mounting member is pivotably attached to said base.

3. The miter saw of claim 1 , wherein:

said base further has a spring, and

said spring is positioned to bias said first mounting member toward said unclamped position.

4. The miter saw of claim 1 , wherein:

said base includes (i) a first foot structure defining a first cavity, and (ii) a second foot structure defining a second cavity,

said first mounting member is at least partially positioned within said first cavity, and

said second mounting member is at least partially positioned within said second cavity.

5. The miter saw of claim 4 , wherein:

said first fastener is externally threaded,

said first bore structure is internally threaded, and

said externally threaded first fastener is meshingly engaged with said internally threaded first bore structure.

6. The miter saw of claim 5 , wherein said externally threaded first fastener extends into said first cavity.

7. The miter saw of claim 1 , wherein:

said miter saw stand includes a first elongated member and a second elongated member,

said first clamping surface and said second clamping surface define a space therebetween, and

both said first elongated member and said second elongated member are positioned in said space when said first actuator is located at said second position.

8. The miter saw of claim 1 , wherein:

said base further has a third mounting member that defines a third clamping surface and is movably attached to said base, a fourth mounting member that defines a fourth clamping surface and is attached in a fixed position to said base, and a second actuator,

wherein said base includes a second bore structure that defines a second fastener passage that extends through said upper surface,

wherein said second actuator includes a second fastener that extends downwardly through said second bore structure and is connected to said second mounting member

said second actuator is movable between a third position and a fourth position in relation to said second bore structure, and

movement of said second actuator from said third position towards said fourth position causes said third clamping surface to move toward said fourth clamping surface.

9. The miter saw of claim 8 , wherein:

said third mounting member is pivotably attached to said base.

10. The miter saw of claim 8 , wherein:

said base further has a second spring, and

said second spring is positioned to bias said third clamping surface away from said fourth clamping surface.

11. The miter saw of claim 8 , wherein:

said body includes a third foot structure defining a third cavity, and a fourth foot structure defining a fourth cavity,

said third mounting member is at least partially positioned within said third cavity, and

said fourth mounting member is at least partially positioned within said fourth cavity.

12. The miter saw of claim 8 , wherein:

said second fastener is externally threaded,

said second bore structure is internally threaded, and

said second externally threaded fastener is meshingly engaged with said second internally threaded bore structure.

13. The miter saw of claim 12 , wherein:

said second externally threaded fastener extends into said third cavity.

14. The miter saw of claim 8 , wherein:

said third clamping surface and said fourth clamping surface define a second space therebetween,

said first space is spaced apart from said second space, and

both said first elongated member and said second elongated member are positioned in said second space when said second actuator is located at said fourth position.
