摘要:
The present invention provides an apparatus for a power saw of the type which has a table top, a rotatable circular saw blade that is vertically adjustable relative to the table top, the table top having an opening through which the saw blade can extend, said apparatus comprising: a blade guard (120) configured to generally cover the portion of the blade extending above the table top, and being pivotally mounted to enable a work piece to be moved into a cutting position by the blade; and a quick release assembly (30) that attaches said blade guard to a riving knife positioned rearwardly of the blade and attached to the saw, said assembly having a mounting portion (130) and a lever (136) that is movable between a release position and a holding position, said blade guard being removable from said riving knife when said lever is in its release position.

A preferred embodiment of the present invention is directed to a modular saw guard system for a power saw of the type which has a table top, a rotatable circular saw blade that is vertically adjustable relative to the table top, the table top having an opening through which the saw blade can extend, the blade being configured to cut a work piece as the work piece is moved forwardly from a forward position to a rearward position, wherein the system comprises a riving knife mechanism (22) releasably mounted to the saw rearwardly of the blade, and being configured to be adjustable between retracted and extended positions relative to the blade, a blade guard mechanism (20) that is releasably mounted to the riving knife mechanism when the riving knife mechanism is at least in its extended position, the blade guard mechanism generally covering the blade and being adjustable to enable a work piece to be moved into cutting position by the blade and a kickback prevention mechanism (26) that is releasably mounted to the riving knife mechanism when the riving knife mechanism is at least in its extended position, the kickback prevention mechanism being configured to engage a work piece as it is being cut by the blade and apply resistance to prevent the work piece from being expelled in the reverse direction.

The present invention provides a kickback prevention apparatus for a power saw of the type which has a table top, a rotatable circular saw blade that is vertically adjustable relative to the table top, the table top having an opening through which the saw blade can extend, the blade being configured to cut a work piece as the work piece is moved from a forward position to a rearward position, and an elongated riving knife mounted to the saw rearwardly of the blade, said apparatus comprising: a bracket having at least one pivot shaft for pivotally supporting at least one elongated kickback arm, with the arm having at least one sharp surface for engaging a work piece to prevent reverse movement of the work piece during a cutting operation; a quick release assembly operatively associated with said at least one pivot shaft for attaching said apparatus to the riving knife, said assembly having a mounting body that is movable on said at least one pivot shaft between a release position and a holding position, said apparatus being removable from the riving knife when said mounting body is in its release position.
摘要:
A collapsible folding stand (10) for use with a portable table saw or other object that is attached to the stand (10) and is capable of being manipulated between open and closed positions. In the closed position, the stand (10) is generally vertically oriented with the object (12) attached to a top frame (14). To open the stand (10) a locking mechanism (40) is released which enables a folding mechanism (20) supporting the top frame (14) to unfold in a manner whereby the rear legs (42) having wheels (48) that separate from forward side struts (22) which contact the ground, with the center of gravity of the object (12) being positioned between the wheels (48) and the front ground contact points so that the weight of the object (12) tends to separate the same and bring the top frame (14) into a generally horizontal position. To move the rolling stand (10) to its closed position, the user needs only to lift the handle (54) and the top frame (14) will then move to its generally vertical closed position.
