Problems solved by technology

But these devices are often difficult to use because they are typically fragile and prevent the operator from viewing the workpiece or saw blade or the reference marks or scales used to align the workpiece
Many guards are therefore usually disassembled, which in turn leads to a higher possibility of accidents and injuries
Additionally, removal of the guard from the table saw often requires the use of tools which complicates and makes adjustment and maintenance of the saw blade and slot wedge

Embodiment Construction

[0021] Although the invention is capable of several different embodiments, the specification and drawings disclose only some specific forms as examples of the invention, including the most preferred embodiment. It is not intended that the invention be limited by the description in the specification or drawings. Instead, the claims indicate the scope of the invention.

[0022] Figure 1 shows a table saw (10) with an improved wedge / guard (20). The table saw includes a table top (12). The table top (12) includes a slot (14). A saw blade (16) is conventionally mounted to a motor and table (both not shown), which are located below the table top (12). The saw blade (16) protrudes through the slot (14). The portion of the saw blade (16) protruding through the slot (14) is the operative portion for cutting a workpiece (not shown).

[0023] A wedge or splitter (22) is also mounted on the table saw. The slot wedge (22) is preferably placed on a stand (not shown) below the table to...

Abstract

A riving knife / guard assembly for a table saw allows the guard to be removed and attached without the use of any tools. It is stated to provide a clear view of the work zone, blade and work piece, and is easily adjustable to accommodate different size work pieces and cutting angle.

Description

Background technique [0001] A typical table saw includes a base or frame that provides or supports a flat table top. The bench top typically includes a slot through which a cutting member, such as a circular saw, protrudes above the bench top. Usually a wedge or splitter is mounted directly in line with the blade. The purpose of the wedge is to keep the two sides of the workpiece part that has been sawn apart. Reduces the chance of the workpiece pinching the saw as it is being cut by keeping the workpiece apart. Table saws also include a guard to protect the operator from potentially serious injury due to accidental contact with the saw blade. Since the guard is positioned in such a manner, it prevents the operator from touching the saw blade when in use. [0002] In the past, many types of wedges and guards have been used. But these devices are often difficult to use because they are typically fragile and prevent the operator from viewing the workpiece or saw blade or re...
