Abstract

A leaning grid device, also referred to as a fence assembly, for a miter saw includes at least one upper leaning grid which is a movable leaning grid having an upper support surface for a work piece and at least one lower leaning grid having a lower support surface for the work piece. The lower leaning grid is also a movable leaning grid and may move between two support positions. The lower support surface and the upper support surface are in a same plane when the lower leaning grid is located at the support positions and the lower support surface and the upper support surface are in different planes when the lower leaning grid is located at a position that is between the support positions.

First claim

What is claimed is:

1. A miter saw comprising:
a base;
a worktable for supporting a workpiece, the worktable being rotatably coupled to the base;
a saw mechanism pivotally coupled to the worktable and including a saw blade for cutting the workpiece;
a bracket mounted to the base; and
a fence assembly supported by the bracket and operably coupled to and disposed above the worktable for supporting the workpiece beneath the saw blade for cutting during operation thereof, the fence assembly comprising:
an upper fence portion operably coupled to the bracket and having an upper support surface for selectively supporting the workpiece, the upper fence portion being movable relative to the worktable; and
a lower fence portion operably coupled to the bracket and having a lower support surface for supporting the workpiece, the lower fence portion being movable between a first support position and a second support position relative to the worktable, and
wherein the lower support surface and the upper support surface are in a same plane with the lower support surface disposed between the upper support surface and the worktable when the lower fence portion is located at the first support position and when the lower fence portion is located at the second support position, and the lower support surface and the upper support surface are in different parallel planes when the lower fence portion is located at a position that is between the first and second support positions.

2. A miter saw according to claim 1 , wherein the fence assembly comprises at least one connecting rod and a first end of the connecting rod is pivotally connected to the bracket and a second end of the connecting rod is pivotally coupled to the lower fence portion.

3. A miter saw according to claim 2 , wherein the at least one connecting rod comprises two connecting rods and wherein the two connecting rods are parallel to each other.

4. A miter saw according to claim 2 , further comprising a spring having a first end connected to the bracket and a second end connected to the lower fence portion.

5. A miter saw according to claim 1 , wherein the bracket comprises at least two openings and the lower fence portion is provided with at least one post for mating with the openings of the bracket.

6. A miter saw according to claim 5 , wherein the bracket further comprises an elastic sheet mounted to the bracket for biasing the lower fence portion towards the bracket.

7. A miter saw according to claim 1 , wherein the bracket is fixedly connected to the base of the miter saw.

8. A miter saw according to claim 1 , wherein the bracket is integrally formed as a part of the base of the miter saw.

9. A miter saw, comprising:
a base;
a worktable rotatably connected to the base;
a bracket fixedly mounted to the base;
a fence supported on the bracket above the worktable and configured for supporting a workpiece; and
a saw mechanism pivotally connected to the worktable and including a saw blade for cutting the workpiece supported on the worktable and against the fence;
wherein the fence comprises:
an upper fence portion movable relative to the worktable and having an upper support surface for supporting the workpiece; and
a lower fence portion movable relative to the worktable and having a lower support surface for supporting the workpiece in cooperation with the upper fence portion,

wherein the lower fence portion is moveable between a first support position and a second support position, and the lower support surface and the upper support surface are in a same plane with the lower support surface disposed between the upper support surface and the worktable when the lower fence portion is located at the first support position and when the lower fence portion is located at the second support position, and the lower support surface and the upper support surface are in different parallel planes when the lower fence portion is located at a position that is between the first and second support positions.

10. The miter saw according to claim 9 , further comprising at least one connecting rod having two ends pivotally connected to the bracket and to the lower fence portion, respectively.

11. The miter saw according to claim 10 , wherein the at least one connecting rod comprises two connecting rods and wherein the two connecting rods are parallel to each other.

12. The miter saw according to claim 10 , comprising a spring having two ends that are connected to the bracket and to the lower fence portion, respectively.

13. The miter saw according to claim 9 , wherein the bracket comprises at least two openings and the lower fence portion is provided with at least one post for mating with the openings.

14. The miter saw according to claim 13 , wherein the fence comprises an elastic sheet which is mounted to the bracket for pulling the lower fence portion towards the bracket.

15. The miter saw according to claim 9 , wherein the bracket is integrally formed as a part of the base.
