Telescoping guide for a concrete saw

Abstract

A saw for cutting concrete includes a readily movable base, a motor connected to the base and includes a cutting blade and drive mechanism operably connected thereto. A handle is provided and is connected to the base and can extend rearwardly and upwardly therefrom so that an operator may stand behind the saw to push it during operation. A telescopic guide is provided on the base and includes a pivot connection to allow folding to a storage or travel position. In a broad sense, the invention is directed to a telescoping guide for a saw, which includes an arm having an end serving as a guiding pointer and a mounting end, and a mechanism connectable to the saw for slidably receiving the mounting end.

What is claimed is:  
     
         1 . A saw for grooving concrete, comprising: 
 a motorized concrete saw having a movable base, a cutting blade, means operably connected with said base for driving said blade such that when said base is disposed on the concrete, said cutting blade is enabled to cut a groove along an intended path in the concrete; and    a telescopic guide connected to said saw in a manner to extend along said intended path to be cut.    
     
     
         2 . The saw of  claim 1 , wherein said telescopic guide is pivotally connected to said base.  
     
     
         3 . The saw of  claim 1 , which includes a handle connected to said base which can extend rearwardly and upwardly therefrom so that an operator may stand behind the saw to push it during operation.  
     
     
         4 . The saw of  claim 1 , wherein said telescopic guide is connected to said base.  
     
     
         5 . The saw of  claim 1 , wherein said telescopic guide includes a pointer which is generally aligned with said cutting path of said blade and capable of remaining adjacent the concrete along the path while said guide is telescoped.  
     
     
         6 . A saw for cutting a groove along a relatively flat surface, comprising: 
 a motorized concrete saw having a movable base, a cutting blade, means operably connected with said base for driving said blade such that when said base is disposed on the surface, said cutting blade is enabled to cut a groove along an intended path in the surface; and    a telescopic guide connected to said saw in a manner to extend along said intended path to be cut.    
     
     
         7 . The saw of  claim 6 , wherein said telescopic guide is pivotally connected to said base.  
     
     
         8 . The saw of  claim 6 , which includes a handle connected to said base which can extend rearwardly and upwardly therefrom so that an operator may stand behind the saw to push it during operation.  
     
     
         9 . The saw of  claim 6 , wherein said telescopic guide is connected to said base.  
     
     
         10 . The saw of  claim 6 , wherein said telescopic guide includes a pointer which is generally aligned with said cutting path of said blade and capable of remaining adjacent the surface along the path while said guide is telescoped.  
     
     
         11 . A telescoping guide for a saw, comprising: 
 an arm having an end serving as a guiding pointer and a mounting end;    means connectable to the saw for slidably receiving said mounting end.
