Abstract

A work supporting device includes an elongated body, an extension plate and a locking unit. The elongated body has elongated first and second sections and an intermediate curved section. A gap is formed between the first and second sections. The curved section is indented from the work supporting faces at the gap. The first section has a first end distal from the second section and a second end proximate to the second section. The extension plate is connected pivotally to the first section of the elongated body. The extension plate is pivotable about an axis transverse to the first section between a first position where the extension plate extends into the gap in order to shield at least a part of the gap, and a second position where the extension plate extends beyond the first end of the first section of the elongated body in order to prolong the length of the first section from the first end of the first section. The locking unit is provided for releaseably locking the extension plate in one of the first and second positions.

Dependent claims

A work supporting device mountable on a worktable of a circular sawing apparatus for use with a movable support to hold and support a workpiece therebetween, said work supporting device comprising:

an elongated body having elongated first and second sections and an intermediate curved section interconnecting said first and second sections, said first and second sections having work engaging faces aligned with one another in a lengthwise direction thereof and having a gap formed therebetween, said curved section being indented from said work engaging faces at said gap, said first section having a first end distal from said second section and a second end proximate to said second section;
an extension plate connected pivotally to said first section of said elongated body, said extension plate being pivotable about an axis transverse to said first section and parallel to said work engaging face of said first section to move between a first position where said extension plate extends into said gap in order to shield at least a part of said gap, and a second position where said extension plate extends beyond said first end of said first section of said elongated body in order to prolong the length of said first section from said first end of said first section;
and
means for releaseably locking said extension plate in one of said first and second positions.
