    摘要： 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.

    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, the blade being configured to cut a work piece as the work piece is forwardly moved from a forward position to a rearward position, said apparatus comprising:
    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, the mechanism having an elongated relatively thin knife (34) that is mounted substantially in the same plane as the blade, the outer upper end of said knife being capable of being positioned below the table top when in its retracted position and extending to an elevation at least approaching the upper reach of the blade when in its extended position.
