Abstract

A miter saw has a base having a detent notch, a table rotatably connectable to the base, a pivoting assembly connected to the table, and a saw assembly supported by the pivoting assembly. The saw assembly has a blade movable downwardly for a cutting operation. A locking mechanism is disposed on the table. The locking mechanism is movable between an unlocked position and a locked position for selectively unlocking and locking the table for rotational movement relative to the base about the miter axis. The locking mechanism has a lock lever rotatably connected to the table. The lock lever has a handle for moving locking mechanism between the locked and unlocked positions. The saw also has a miter detent assembly for selectively engaging and disengaging the detent notch.

First claim

What is claimed is:

1. A miter saw comprising:
a base having a detent notch;
a table rotatably connectable to the base, the table being rotatable about a substantially vertical miter axis and having a substantially horizontal workpiece-supporting plane;
a pivoting assembly connected to the table;
a saw assembly supported by the pivoting assembly, the saw assembly comprising a blade, the blade being movable for a cutting operation downwardly from a first position where the blade is above the workpiece-supporting plane to a second position where a portion of the blade is below the workpiece-supporting plane;
a fence connected to the base assembly, the fence defining a fence plane perpendicular to the workpiece-supporting plane;
a locking mechanism disposed on the table, the locking mechanism being movable between an unlocked position and a locked position for selectively unlocking and locking the table for rotational movement relative to the base about the miter axis, the locking mechanism comprises a lock lever rotatably connected to the table, the lock lever having a handle for moving the locking mechanism between the locked and unlocked positions; and
a miter detent assembly for selectively engaging and disengaging the detent notch, wherein the miter detent assembly is pivotably attached to the table, the miter detent assembly comprising:
a body attached to the table, the body having a detent portion,
a first detent override assembly for moving the detent portion from a first position engaging the detent notch and a second position not engaging the detent notch, the first detent override assembly comprising a lever pivotally attached to the table and contacting the body, and an actuator pivotally attached to the table and contacting the lever; and
a second detent override mechanism for maintaining the body in the second position without activating the actuator.

2. The miter saw of claim 1 , wherein the locking mechanism further comprises:
a rod connected to the lock lever;
a rod extension slidingly movable towards the table, the rod extension contacting the rod; and
a clamping plate disposed between the table and the rod extension, wherein the clamping plate contacts the table and the rod extension when the locking mechanism is in the locked position;
wherein a force applied by the clamping plate when the locking mechanism is in the locked position is aligned with at least one of the miter axis and a line along the intersection of blade and the workpiece-supporting plane.

3. The miter saw of claim 1 , wherein the actuator has a handle.

4. The miter saw of claim 1 , wherein the actuator is pivotably connected to the table via a pin.

5. The miter saw of claim 4 , wherein the second detent override mechanism is pivotably disposed on the pin.

6. The miter saw of claim 5 , wherein the second detent override mechanism has a handle.

7. The miter saw of claim 1 , wherein the second detent override mechanism contacts the lever.

8. The miter saw of claim 1 , further comprising a plurality of guide rails slidingly disposed on the pivoting assembly and connected to the saw assembly.
