Slide compound saws

Abstract

Slide compound saws ( 1, 100, 150 ) may include a table ( 3 b ) defining a table surface. A saw unit ( 20 ) may be pivotable relative to the table surface. A first slide bar ( 31, 51, 251, 351 ) may be slidably coupled to the table and may be disposed substantially in parallel with the table surface. The first slide bar may define a first sliding distance (S 1 ) of the saw unit in a direction substantially parallel to the table surface. A sliding device ( 24, 33, 52, 61, 62, 252, 352 ) may slidably couple the first slide bar to the saw unit. The sliding device may define a second sliding distance (S 2 ) of the saw unit in the direction substantially parallel to the table surface. Preferably, the saw unit can slide up to a distance S 1 plus S 2 in the direction substantially parallel to the table surface.

1 - 21 . (canceled) 
   
   
       22 . A slide compound saw comprising:
 a table defining a table surface,   a saw unit rotatably supporting a circular saw blade,   first and second slide mechanisms each arranged and constructed to enable the saw unit to slide in a direction substantially parallel to the table surface,   a first slide bar slidably supporting the saw unit relative to the table, and   an arm holder supporting the saw unit and being slidably coupled to the first slide bar, wherein the first slide mechanism slidably couples the table to the first slide bar and defines a first slidable range of the first slide bar relative to the table, and the second slide mechanism slidably couples the first slide bar to the arm holder and defines a second slidable range of the arm holder relative to the first slide bar.   
   
   
       23 . A slide compound saw as in  claim 22 , further including a hinge enabling the saw unit to pivot relative to the arm holder and means for laterally inclining the saw unit relative to the arm holder. 
   
   
       24 - 31 . (canceled) 
   
   
       32 . The slide compound saw as in  claim 22 , wherein:
 the first slide bar comprises two slide bars that are substantially in parallel to each other; and   the arm holder is mounted between the two slide bars via the second slide mechanism.   
   
   
       33 . The slide compound saw as in  claim 22 , wherein the second slide mechanism comprises a linear ball bearing. 
   
   
       34 . The slide compound saw as in  claim 22 , further comprising a stopper mechanism disposed on the first slider bar and arranged and constructed to limit a movable range of the arm holder relative to the first slide bar. 
   
   
       35 . An apparatus comprising:
 a base;   a table defining a substantially horizontal table surface and rotatably supported on the base, so that the table can rotate within a substantially horizontal plane; a slide bar slidably mounted to the table, so that the slide bar can move substantially in a radial direction with respect to a rotational axis of the table;   an arm holder slidably mounted to the slide bar, so that the arm holder can move in an axial direction of the slide bar;   an arm pivotally mounted to the arm holder, so that the arm can pivot about an axis that extends substantially parallel to the axial direction of the slide bar; and   a saw unit vertically pivotally mounted to the arm and having a rotary saw blade supported thereon.   
   
   
       36 . The apparatus as in  claim 35 , wherein:
 the slide bar includes a first end positioned within the table and a second end radially outward of the table; and   the arm holder is slidably mounted to the second end of the slide bar.   
   
   
       37 . The apparatus as in  claim 35 , wherein:
 the slide bar comprises first and second slide bars extending in substantially parallel to each other; and   the arm holder is mounted to the first and second slide bars so as to extend therebetween.
