Attachable and Extendable Saw and Methods for Using Same

Abstract

An attachable and extendable saw and methods for cutting objects with the attachable and extendable saw are provided. The attachable and extendable saw can include a blade housing coupled to a main body. The blade housing at least partially covers a saw blade and the extendable member can be configured to move the saw blade with or without the blade housing between a retracted position and an extended position relative to the main body. The extendable saw can also include means to drive the saw blade, means to drive the extendable member, and means for attaching the attachable and extendable saw to the objects to be cut.

What is claimed is: 
     
         1 . An attachable and extendable saw comprising:
 a main body;   a saw blade housing coupled to the main body by an extendable member, wherein the saw blade housing sits flat against a work surface and in a parallel plane to the work surface which holds an object to be cut by a saw blade and at least partially covers the saw blade, and the extendable member is configured to move the saw blade in a linear direction between a retracted position and an extended position relative to the main body;   a motorized unit coupled to the saw blade and configured to drive the saw blade by saw blade driving means;   actuator means coupled to the extendable member and configured to drive the extendable member by extendable member driving means;   attaching means disposed on the main body for attaching the attachable and extendable saw to the work surface; and   a control system operatively coupled to one or more of the extendable member, the motorized unit, the actuator means, and the attaching means,   wherein the saw blade fits flat against said work surface holding the object to be cut, which object protrudes from the work surface.   
     
     
         2 . The attachable and extendable saw of  claim 1  wherein the extendable member is configured to move the saw blade with or without the saw blade housing in a linear direction or a non-linear direction between the retracted position and the extended position relative to the main body. 
     
     
         3 . The attachable and extendable saw of  claim 1  wherein the attaching means comprises vacuum means. 
     
     
         4 . A vacuum-attachable and extendable saw, comprising:
 a main body;   a saw blade housing coupled to the main body by an extendable member, wherein the saw blade housing sits flat against a work surface and in a parallel plane to the work surface which holds an object to be cut by a saw blade and at least partially covers the saw blade, and the extendable member is configured to move the saw blade in a linear direction between a retracted position and an extended position relative to the main body;   a motorized unit coupled to the saw blade and configured to drive the saw blade by saw blade driving means;   actuator means coupled to the extendable member and configured to drive the extendable member by extendable member driving means;   a vacuum-attachable unit disposed on the main body and comprising at least one contact surface that is switchable between a vacuum state and a non-vacuum state.   a control system operatively coupled to one or more of the extendable member, the motorized unit, the actuator means, and the attaching means,   wherein the saw blade fits flat against said work surface holding the object to be cut, which object protrudes from the work surface.   
     
     
         5 . A method for cutting an object protruding from a work surface with an extendable saw, comprising:
 positioning the extendable saw on or adjacent to the work surface, the extendable saw comprising:
 a main body; 
 a saw blade housing coupled to the main body by an extendable member, wherein the saw blade housing sits flat against a work surface and in a parallel plane to the work surface which holds an object to be cut by a saw blade and at least partially covers the saw blade, and the extendable member is configured to move the saw blade in a linear direction between a retracted position and an extended position relative to the main body; 
 a motorized unit coupled to the saw blade and configured to drive the saw blade by saw blade driving means; 
 actuator means coupled to the extendable member and configured to drive the extendable member by extendable member driving means; 
 attaching means disposed on the main body for attaching the attachable and extendable saw to the work surface; 
 a control system operatively coupled to one or more of the extendable member, the motorized unit, the actuator means, and the attaching means, 
 wherein the saw blade fits flat against said work surface holding the object to be cut, which object protrudes from the work surface; 
   attaching the extendable saw to the work surface by activating the attaching means;   driving the saw blade via the motorized unit;   extending the saw blade with or without the blade housing from the retracted position towards the object protruding from the work surface, wherein the object is disposed between the retracted position and the extended position; and   cutting the object with the saw blade.   
     
     
         6 . A circular saw blade for attachment to a base plate coupled to a motorized unit to drive the saw blade,
 the saw blade having a side panel surface extending radially inwardly from teeth,   the side panel surface facing away from the base plate when the sawblade is mounted on the base plate,   at least one hole arranged between a center of the saw blade and the teeth,   the hole including a countersink, and at least one orifice arranged between the center of the saw blade and the teeth.   
     
     
         7 . The circular saw blade of  claim 6 , wherein the at least one orifice is located approximately 90 degrees from an adjacent second orifice and equidistant from the center of the saw blade. 
     
     
         8 . The circular saw blade of  claim 6  wherein the at least one hole is located 90 degrees from any adjacent second hole. 
     
     
         9 . The circular saw blade of  claim 6  wherein the at least one orifice is farther from the center of the saw blade than the at least one hole is from the center of the saw blade.
