  • Patent number: 9446536
    Abstract: A safety component is provided for a power saw that includes a rear guard pivotably mounted to the saw assembly. The rear guard is generally U-shaped to straddle the cutting blade in a deployed position. The rear guard includes arms that contact the workpiece during the cutting operation so that as the saw blade moves downward to perform the cut the rear guard pivots upward while maintaining protection of the rear portion of the saw blade.

  • Patent number: 9283628
    Abstract: A chop saw includes a base assembly and a saw assembly pivotally attached to the base assembly. The base assembly has a workpiece-supporting plane. The saw assembly has a blade and a motor driving the blade. A hinged connection between the base assembly and a saw assembly allows a user to rotate the saw assembly from a position where the plane of the blade extends through the workpiece-supporting plane to a position where the plane of the blade does not extend through the workpiece-supporting plane. In such position, the plane of blade may be substantially parallel to the workpiece-supporting plane.

  • Patent number: 9126275
    Abstract: A circular saw includes a machine base, a sliding unit having a slide shaft slidably inserted through the machine base and a stationary mount fixedly mounted at one end of the slide shaft and defining a datum plane, and a cutting unit having a supporting arm pivotally connected to the stationary mount and a saw blade pivotally connected to the supporting arm. The saw blade is movable by the supporting arm up and down relative to the machine base between a lower limit position and an upper limit position so that the saw blade may intersect with the datum plane or be kept in a tangential relationship relative to the datum plane when it reaches the lower limit position. Thus, the circular saw has a compact size, low vibration level and high precision characteristics.

  • Patent number: 9032851
    Abstract: An adjustment device for an auxiliary fence includes a support frame, an auxiliary fence, a guiding unit and an adjusting unit. The guiding unit guides the auxiliary fence along a longitudinal direction such that the auxiliary fence is selectively slidable relative to the support frame. The adjusting unit allows the auxiliary fence to be adjusted relative to the support frame and securely positioned. The adjusting unit includes a driving member, a securing member installed on the driving member, and an elastomeric element. When the driving member is operated, the securing member becomes disengaged from the support frame which allows the position of the auxiliary fence to be adjusted by sliding it relative to the support frame.
