Folding saw horse

Abstract

An improved folding saw horse has a main beam support member and pivotable legs connected thereto by bolts with locking nuts which pass through pivot bores in the main beam support member. The main beam support member is reinforced by a pair of end flex support members at opposite ends thereof. The main beam support member also includes bores which receive securement pins. In use the securement pins would be disposed in a lowermost set of bores in the main beam support member to lock the legs in position. There are also an upper set of bores to receive the securement pins 70 when the legs are in a folded position within the body of the main beam support member. The securement pins retain the legs within the interior of the main beam support member. The main beam support member is a generally inverted U-shaped member having angled sidewalls which preferably extend at an angle of approximately 70 degrees from the plane of the uppermost surface of the main beam support member.

1 . A folding saw horse, comprising: 
 a main beam support member;    a plurality of legs pivotably connected to the main beam support member; and    a plurality of securement pins for securing each of said plurality of legs in one of a folded position and an extended position.    
   
   
       2 . A folding saw horse as claimed in  claim 1 , wherein each of said plurality of securement pins is spring biased toward a securement position.  
   
   
       3 . A folding saw horse as claimed in  claim 1 , wherein the main beam support member has an upper support member having a surface adapted for supporting a load, and two side walls extending from opposite sides of said upper support member.  
   
   
       4 . A folding saw horse as claimed in  claim 3 , wherein each of said two side walls includes two bores corresponding to each leg for receiving respective ones of said securement pins, one of the two bores being disposed for securement of a respective one of said securement pins to lock a respective one of the legs in a folded position, and the other one of the two bores being disposed for securement of the respective one of the securement pins to lock the respective one of the legs in an extended position.  
   
   
       5 . A folding saw horse as claimed in  claim 4 , wherein each of said plurality of securement pins is spring biased toward a securement position.  
   
   
       6 . A folding saw horse as claimed in  claim 3 , wherein the main beam support member has a form which is an inverted U-shape; and further comprising two end flex support members disposed on opposite ends of the main beam support member; each of the two end flex support members having opposite ends thereof secured to respective ones of said two side walls of said main beam support member so as to provide reinforcement thereof.  
   
   
       7 . A folding saw horse as claimed in  claim 6 , wherein in the folded position, each of the legs is disposed entirely within a volume bounded by the inverted U-shape of main beam support member.  
   
   
       8 . A folding saw horse, comprising: 
 a main beam support member;    a plurality of legs pivotably connected to the main beam support member;    a plurality of securement pins for securing each of said plurality of legs in one of a folded position and an extended position; and    a sensing means disposed on each of said plurality of securement pins for sensing correct disposition of the respective one of said plurality of securement pins.    
   
   
       9 . A folding saw horse as claimed in  claim 1 , wherein each of said plurality of securement pins is spring biased toward a securement position; and wherein the securement pins each comprise a shaft, a washer secured to said shaft adapted for engagement with an internal wall of a leg when the securement pin is in a secured position.  
   
   
       10 . A folding saw horse as claimed in  claim 9 , wherein the main beam support member has an upper support member having a surface adapted for supporting a load, and two side walls extending from opposite sides of said upper support member.  
   
   
       11 . A folding saw horse as claimed in  claim 10 , wherein each of said two side walls includes two bores corresponding to each leg for receiving respective ones of said securement pins, one of the two bores being disposed for securement of a respective one of said securement pins to lock a respective one of the legs in a folded position, and the other one of the two bores being disposed for securement of the respective one of the securement pins to lock the respective one of the legs in an extended position.  
   
   
       12 . A folding saw horse as claimed in  claim 8 , wherein each of said plurality of securement pins is spring biased toward a securement position.  
   
   
       13 . A folding saw horse as claimed in  claim 10 , wherein the main beam support member has a form which is an inverted U-shape; and further comprising two end flex support members disposed on opposite ends of the main beam support member; each of the two end flex support members having opposite ends thereof secured to respective ones of said two side walls of said main beam support member so as to provide reinforcement thereof.  
   
   
       14 . A folding saw horse as claimed in  claim 13 , wherein in the folded position, each of the legs is disposed entirely within a volume bounded by the inverted U-shape of main beam support member.  
   
   
       15 . A folding saw horse as claimed in  claim 9 , wherein said sensing means includes a battery and a magnetic sensor disposed on said washer.  
   
   
       16 . A folding saw horse as claimed in  claim 9 , wherein said sensing means includes a battery and a magnetic sensor disposed on said washer; and further comprising an indicating means responsive to said magnetic sensor, for indicating an incorrect positioning of the respective securement pin.  
   
   
       17 . A folding saw horse as claimed in  claim 8 , further comprising an indicating means for indicating an incorrect positioning of the respective securement pin.  
   
   
       18 . A folding saw horse as claimed in  claim 8 , further comprising an indicating means forindicating an incorrect positioning of the respective securement pin; and wherein thesecurement pins include a shaft having an optically transparent core.
