Abstract
A table saw includes a workpiece support surface and a laser apparatus. The workpiece support surface defines a blade opening through which a cutting blade is configured to extend. The laser apparatus is configured to emit a laser light away from the workpiece support surface. A laser support element having an upper portion above the workpiece support surface and a lower portion below the workpiece support surface, and the laser apparatus is connected to the lower portion, and the reflective surface is positioned on the upper portion to reflect the laser light toward the support surface to visually indicate a position.
Claims16
A table saw comprising:
- a workpiece support surface defining a blade opening through which a cutting blade is configured to extend;
- and
- a laser apparatus configured to emit a laser light away from the workpiece support surface;
- and
- a riving knife having an upper knife portion positioned above the workpiece support surface and a lower knife portion positioned below the workpiece support surface;
- wherein (i) the laser apparatus is connected to the lower knife portion, and (ii) a reflective surface is connected to the upper knife portion to reflect the laser light toward the support surface to visually indicate a position.
A table saw comprising:
- a workpiece support surface defining a blade opening through which a cutting blade is configured to extend;
- a light apparatus configured to emit a beam of light;
- and
- a reflective surface operably positioned to reflect the beam of light onto the workpiece support surface;
- and
- a riving knife having an upper knife portion positioned above the workpiece support surface and a lower riving knife portion positioned below the workpiece support surface;
- and optionally a blade guard may be connected to the upper knife portion of the riving knife,
- wherein (i) the light apparatus is connected to the lower knife portion, and (ii) a reflective surface is connected to one of the upper knife portion and the optional blade guard to reflect light from the light apparatus toward the support surface to visually indicate a position.
An optical alignment device with a table saw comprising:
- A table saw having a work support;
- and
- a laser apparatus configured for connection to the table saw and configured to emit a laser light away from a workpiece support surface of the table saw;
- and
- a reflective surface configured for connection to the table saw and operably positioned to reflect the laser light toward the workpiece support surface;
- and
- A laser support element having an upper portion above the workpiece support surface and a lower portion below the workpiece support surface, and the laser apparatus is connected to the lower portion, and the reflective surface is positioned on the upper portion to reflect the laser light toward the support surface to visually indicate a position.
