Blank for a sink

Abstract

A drawn blank of metal is provided to define the floor of a subsequently formed commercial sink. A flat strip of metal is folded and welded at the abutting ends to form a peripheral frame which can then be seated on the blank and welded thereto. The peripheral frame may be of any suitable height so as to permit the blank to be used to make sinks of different heights.

What is claimed is:  
     
         1 . A blank for a sink comprising 
 a drawn one piece metal body having a floor and an upstanding wall extending peripherally of said floor, said wall having an upper flat edge disposed in a horizontal plane.    
     
     
         2 . A blank as set forth in  claim 1  wherein said body is made of stainless steel.  
     
     
         3 . A blank as set forth in  claim 1  wherein said wall is vertically disposed relative to said horizontal plane and has a height of from 0.5 inches to 5.0 inches.  
     
     
         4 . A blank as set forth in  claim 1  further comprising a radiused edge connecting said floor with said wall.  
     
     
         5 . A blank as set forth in  claim 4  wherein said wall is of rectangular shape having opposite walls disposed in parallel relation.  
     
     
         6 . A blank as set forth in  claim 4  wherein said floor is of rectangular shape.  
     
     
         7 . A blank as set forth in  claim 6  wherein said floor has an opening therein and a plurality of creases extending radially of said opening.  
     
     
         8 . A blank as set forth in  claim 1  wherein said floor and said blank is of a thickness equal to or less than 14 gauge.  
     
     
         9 . A one piece blank for a sink comprising 
 a rectangular floor of metal having a thickness of up to 14 gauge,    an upstanding wall extending peripherally of said floor, said wall having a thickness equal to said thickness of said floor, opposite parallel sides and an upper flat peripheral edge disposed in a horizontal plane, and    a radiused peripheral portion integrally connecting said floor with said wall.    
     
     
         10 . A sink comprising 
 a drawn one piece metal body defining a floor and an upstanding wall extending peripherally of said floor; and    a peripheral metal frame welded to and extending upwardly from said wall of said body.    
     
     
         11 . A sink as set forth in  claim 10  wherein said metal frame is formed of at one strip with a pair of longitudinally disposed ends welded to each other.  
     
     
         12 . A sink as set forth in  claim 10  wherein said metal body has a flat upper peripheral edge and said frame has a flat lower peripheral edge facing said edge of said body and welded thereto.  
     
     
         13 . A sink as set forth in  claim 10  wherein said wall of said body has has a height of between 0.5 inches and 5.0 inches and frame has a height of from 5 inches to 30 inches.  
     
     
         14 . A method of fabricating a sink comprising the steps of 
 obtaining a drawn one piece metal body defining a floor and an upstanding wall of predetermined shape extending peripherally of said floor;    obtaining a metal frame of a shape corresponding to said shape of said peripheral wall of said metal body; and    welding said frame to said wall of said body in an upwardly extending manner while forming a weld bead extending along the periphery of said wall.    
     
     
         15 . A method as set forth in  claim 14  further comprising the step of polishing said weld bead internally of said frame and externally of said frame to form smooth surfaces coincident with an outside surface and an inside surface respectively of said frame.  
     
     
         16 . A method as set forth in  claim 14  wherein said metal body has an upper flat peripheral edge and said metal frame has a lower flat peripheral edge and wherein said frame is positioned on said body with said respective edges in facing relation to each other during said step of welding.
