    Abstract: The present invention relates to a table saw having a stationary worktable having a work surface, a base for supporting the worktable, a motor-driven cutting device mounted between the worktable and base and at least one auxiliary support device disposed beside the worktable. The auxiliary support device is pivotal relative to the stationary table and the auxiliary support device can be converted between a extended position and a folded position. The auxiliary support device pivots upwardly when it converts from the extended position to the folded position and provides adequate support for making accurate cuts and is convenient to store or transport.

  • Publication number: 20080156161
    Abstract: The invention provides a positioning device for a saw blade elevating platform of a wood sawing machine. More specifically, when a transmission base for controlling a saw blade to elevate in the wood sawing machine is elevated to and positioned at a predetermined position, a predetermined pressing bar disposed in a guiding seat of a mounting seat, at which the elevating platform is located, is pressed by external screws to force the elevating platform to be positioned at a set position. Thus, the saw blade, which is rotated at the high rotating speed and is applied with a high reaction force, can be held absolutely stable, and the operating stability and the precision can be greatly enhanced.

  • Publication number: 20080066598
    Abstract: A convertible miter/table saw comprises a base frame supporting a lower, miter saw table rotatable about a vertical axis. A circular saw assembly, namely a saw blade and motor, is mounted on a rear pedestal of the table and pivotable about a horizontal axis, the miter saw table providing a turntable and having a lower saw slot for receiving the saw blade. In miter saw mode, the swivel position of the miter saw table is adjusted and the circular saw blade moved downwards into the lower saw slot. In table saw mode, an upper saw table connected to the rear of the base frame is pivoted about a horizontal axis from a raised, generally vertical position to a lowered, generally horizontal position in which a slot in the upper saw table accommodates the circular saw blade when the latter is aligned therewith.

  • Patent number: 6854495
    Abstract: A collapsible table assembly having improved portability. A mechanism interconnects the table and supporting legs for moving the legs between a diverging supporting position, a folding position, and a storage position. A saw track assembly includes an upper platform for receiving a cutting device and a lower platform for supporting a workpiece during cutting connected to the upper platform. Each of the upper and lower platform are disposed above the table. A guide pin pivotally attaches the saw track to the table for allowing the saw track to pivot through a plane parallel to the table. A plurality of material supports supported by the table rotate between a first material supporting position for supporting a workpiece and a second unobstructing position for allowing the saw track to freely pivot through the plane without contacting the material supports.
