Dust collection arrangement for a miter saw

Abstract

A miter saw includes a base, a table rotatably attached to the base, a support housing connected to the table, a saw assembly connected to the support housing, the saw assembly comprising a pivot arm, an upper blade guard connected to the pivot arm, a motor attached to the upper blade guard, and a blade driven by the motor, and a dust collector having a main body, wherein at least one slot is disposed on the main body.

What is claimed is:  
     
         1 . A miter saw comprising: 
 a base;    a table rotatably attached to the base;    a support housing connected to the table;    a saw assembly connected to the support housing, the saw assembly comprising a pivot arm, an upper blade guard connected to the pivot arm, a motor attached to the upper blade guard, and a blade driven by the motor; and    a dust collector having a main body, wherein a first slot is disposed on the main body.    
     
     
         2 . The miter saw of  claim 1 , wherein the main body has a second slot.  
     
     
         3 . The miter saw of  claim 2 , wherein the main body has a flap partly delimited by the first and second slots.  
     
     
         4 . A miter saw comprising: 
 a base;    a table rotatably attached to the base;    a support housing connected to the table; and    a saw assembly connected to the support housing, the saw assembly comprising a pivot arm, an upper blade guard connected to the pivot arm, a motor attached to the upper blade guard, and a blade driven by the motor and partly disposed within the upper blade guard,    wherein the upper blade guard defines a cavity, the upper blade guard having a rib within the cavity, the rib being substantially perpendicular to a plane defined by the blade.    
     
     
         5 . The miter saw of  claim 4 , wherein the rib lies along a plane which intersects a rotational axis of the blade.  
     
     
         6 . The miter saw of  claim 4 , wherein the rib is substantially flat.  
     
     
         7 . The miter saw of  claim 4 , wherein the rib is unitary with the upper blade guard.
