Abstract

A fence system for a miter saw is configured to be adjusted along a horizontal axis while remaining aligned with the support table. The fence system includes a fence body defining first and second slots and an aperture, and a fixed base including first, second, and third bores. A first bushing extends through the first slot and includes a first opening, and a second bushing extends through the second slot and includes a second opening. A first fastener extends through the first opening into the first bore to clamp the first bushing to the fixed base, a second fastener extends through the second opening into the second bore to clamp the second bushing to the fixed base, and a third fastener extends through the opening into the third bore to releasably clamp the fence body to the fixed base.

First claim

What is claimed is:

1. A fence system for a miter saw assembly having a fixed base, comprising: a fence body including an abutment surface and defining a first slot having a first width, a second slot having a second width, and an aperture; the fixed base including a first bore, a second bore, and a third bore;
a first bushing including a first opening and having a first diameter that is substantially equal to the first width, the first bushing extending through the first slot;
a second bushing including a second opening and a second diameter that is substantially equal to the second width, the second bushing extending through the second slot;
a first fastener extending through the first opening into the first bore and configured to clamp the first bushing to the fixed base;
a second fastener extending through the second opening into the second bore and configured to clamp the second bushing to the fixed base; and
a third fastener extending through the aperture in the fence body into the third bore, the third fastener being configured to releasably clamp the fence body to the fixed base.

2. The fence system of claim 1 , wherein the aperture in the fence body defines a third slot.

3. The fence system of claim 2 , wherein:
the first slot defines a first longitudinal axis, the second slot defines a second longitudinal axis, and the third slot defines a third longitudinal axis, and
the first, second, and third longitudinal axes are parallel to a plane defined by the abutment surface of the fence body.

4. The fence system of claim 1 , wherein:
the first bushing includes a first cylindrical body and a first outwardly extending flange outside the first slot; and
the second bushing includes a second cylindrical body and a second outwardly extending flange outside the second slot.

5. The fence system of claim 4 , wherein the second cylindrical body is eccentric with respect to the second opening and the second outwardly extending flange such that rotation of the second outwardly extending flange moves the slot with respect to the second fastener in a direction parallel to the second width to adjust an alignment of the abutment surface.

6. The fence system of claim 5 , wherein the second outwardly extending flange is generally hexagonally shaped.

7. The fence system of claim 1 , wherein:
the fence body includes an elongated base portion and an elongated support portion, which are perpendicular with respect to one another;
the elongated support portion includes the abutment surface; and
the first and second slots and the aperture are defined in the elongated base portion.

8. The fence system of claim 7 , wherein a first end of the elongated support portion tapers to an edge having a reduced height.

9. The fence system of claim 1 , wherein the aperture in the fence body is interposed between the first slot and the second slot.

10. The fence system of claim 1 , wherein the first slot, second slot, and aperture are positionally fixed relative to one another.

11. A miter saw assembly, comprising:
a miter saw having a motor configured to rotationally drive a saw blade;
a support table configured to support the miter saw and including (i) a fixed base having a first bore, a second bore, and a third bore, (ii) a bevel mount configured to support the miter saw pivotably about a first horizontal axis, and (iii) a rotatable support configured to support the miter saw rotatably about a vertical axis, the fixed base and the rotatable support defining a work surface normal to the vertical axis;
a fence body including an abutment surface orthogonal to the work surface and defining a first slot having a first width, a second slot having a second width, and an aperture;
a first bushing including a first opening and a first diameter that is substantially equal to the first width, the first bushing extending through the first slot;
a second bushing including a second opening and a second diameter that is substantially equal to the second width, the second bushing extending through the second slot;
a first fastener extending through the first opening into the first bore and configured to clamp the first bushing to the fixed base;
a second fastener extending through the second opening into the second bore and configured to clamp the second bushing to the fixed base; and
a third fastener extending through the aperture into the third bore, the third fastener being configured to releasably clamp the fence body to the fixed base.

12. The miter saw assembly of claim 11 , wherein the aperture in the fence body defines a third slot.

13. The miter saw assembly of claim 12 , wherein:
the first slot defines a first longitudinal axis, the second slot defines a second longitudinal axis, and the third slot defines a third longitudinal axis, and
the first, second, and third longitudinal axes are parallel to a plane defined by the support surface of the flange body and orthogonal to the first horizontal axis and the vertical axis.

14. The miter saw assembly of claim 11 , wherein:
the first bushing includes a first cylindrical body and a first outwardly extending flange outside the first slot; and
the second bushing includes a second cylindrical body and a second outwardly extending flange outside the second slot.

15. The miter saw assembly of claim 14 , wherein the second cylindrical body is eccentric with respect to the second opening and the second outwardly extending flange such that rotation of the second outwardly extending flange moves the second slot with respect to the second fastener in a direction parallel to the first horizontal axis to adjust an alignment of the abutment surface.

16. The miter saw assembly of claim 15 , wherein the second outwardly extending flange is generally hexagonally shaped.

17. The miter saw assembly of claim 11 , wherein:
the fence body includes an elongated base portion and an elongated support portion, which are perpendicular with respect to one another;
the elongated support portion includes the abutment surface; and
the first and second slots and the aperture are defined in the elongated base portion.

18. The miter saw assembly of claim 17 , wherein a first end of the elongated support portion tapers to an edge having a reduced height.

19. The miter saw assembly of claim 11 , wherein the aperture in the fence body is interposed between the first slot and the second slot.

20. A fence system for a miter saw assembly having a fixed base, comprising: a fence body including an abutment surface and defining a first slot having a first width and a second slot having a second width; the fixed base including a first bore and a second bore;
a first bushing including a first opening and having a first diameter that is substantially equal to the first width, the first bushing extending through the first slot;
a second bushing including a second opening, a cylindrical body, an outwardly extending flange, and a second diameter that is substantially equal to the second width, the second bushing extending through the second slot such that the cylindrical body is positioned within the second slot and the outwardly extending flange is outside the second slot;
a first fastener extending through the first opening into the first bore and configured to clamp the first bushing to the fixed base; and
a second fastener extending through the second opening into the second bore and configured to clamp the second bushing to the fixed base,
wherein the cylindrical body is eccentric to the second opening and t
