Abstract

Inserts for use in table saws are disclosed. One embodiment may include a mechanism to lock mechanically and affirmatively the insert in a blade opening in a table saw. The mechanism is designed so that a user can install and remove the insert without tools. The mechanism also can be designed so that the front of the insert pops up above the table when released from its locked position. The mechanism can be further designed so that the insert can be unlocked or released by a user pressing a button or tab.

First claim

The invention claimed is:

1. A table saw comprising:
a table having an opening;
a substantially planar, circular blade configured to extend at least partially above the table through the opening;
an insert configured to fit within the opening, where the insert has a front end, and where the insert includes a first edge; and
a latch to hold down the front end of the insert mechanically, where the latch includes a second edge, where the first edge and the second edge overlap automatically when the front end of the insert is pressed down into the opening, and where the overlapping of the first edge and the second edge holds down the front end of the insert mechanically;
where the first edge is a screw head and the second edge is part of a bracket; and
where the second edge comprises a slot in the bracket, and where the screw head extends into the slot to hold down the front end of the insert mechanically.
