Dustless one-stroke cut-through saw

Abstract

A saw system capable of cutting through a workpiece in one stroke is provided. The saw system includes a base, a turntable mounted on the base for rotation about a vertical axis, a support structure defining a cutting axis and fixedly attached to the turntable, and an elongated blade including a cutting edge. The turntable has a substantially planar support surface for supporting a workpiece. The support structure includes a pair of parallel sliding members having proximal and distal ends. The saw system further includes a handle assembly coupled with a bearing member, which is mechanically engaged with the sliding members, and an elongated blade fixedly attached to the bearing member. The elongated blade includes a serrated cutting edge that is acutely angled relative to the support surface.

What is claimed is: 
     
         1 . A saw system comprising:
 a base,   a turntable mounted on the base for rotation about a vertical axis, wherein the turntable has a substantially planar support surface for supporting a workpiece,   a support assembly fixedly attached to the turntable and defining a cutting axis, wherein the support structure comprises:   two parallel sliding members comprising proximal ends and distal ends,   a handle assembly coupled with a bearing member, which is mechanically engaged with the sliding members in a manner which permits translational movement of the bearing member along the sliding members between a first position, wherein the bearing member is located at the proximal ends of the sliding members, and the second position, wherein the bearing member is located at the distal ends thereof, and   an elongated blade fixedly attached to the bearing member, wherein the elongated blade comprises a serrated cutting edge that is acutely angled relative to the support surface, wherein the elongated blade is movable along the sliding members such that, at the first position, the elongated blade partially passes the proximal ends of the sliding members, and, at the second position, the elongated blade partially passes the distal ends thereof,   wherein the elongated blade is configured to cut through the workpiece in one push stroke.   
     
     
         2 . The saw system of  claim 1 , wherein the cutting edge comprises a portion having a straight contour, a portion having a curved contour, or a combination thereof. 
     
     
         3 . The saw system of  claim 2 , wherein the curved contour has a convex shape. 
     
     
         4 . The saw system of  claim 1 , wherein the sliding members are acutely angled relative to the support surface. 
     
     
         5 . The saw system of  claim 1 , wherein the angle between the serrated cutting edge and the support surface is smaller than the angle between the sliding members and the support surface. 
     
     
         6 . The saw system of  claim 1 , wherein the sliding members are rods disposed one over the other. 
     
     
         7 . The saw system of  claim 1 , wherein the turntable further comprises a slot coextensive with the cutting axis. 
     
     
         8 . The saw system of  claim 1 , wherein a lower portion of the elongated blade is positioned inside the slot. 
     
     
         9 . The saw system of  claim 1 , wherein a higher portion of the elongated blade is positioned outside the slot. 
     
     
         10 . The saw system of  claim 1 , wherein the elongated blade is engaged with the support structure through a carrying assembly. 
     
     
         11 . The saw system of  claim 1 , wherein the carrying assembly is a panel fixedly attached to the elongated blade. 
     
     
         12 . The saw system of  claim 1 , wherein the elongated blade is a SharpTooth™ 15″ hand saw blade. 
     
     
         13 . The saw system of  claim 1 , wherein the workpiece comprises wood or plastic. 
     
     
         14 . The saw system of  claim 1 , wherein the workpiece is a dowel, a pipe, a floor trim, a door trim, a window trim, a ceiling trim, a wall trim, or a multi-purpose trim.
