Stackable scaffolding frames

Abstract

A scaffolding frame comprises a pair of spaced apart elongated vertical members having respective top and bottom ends thereof and at least one elongated horizontal member mounted at each longitudinal end thereof to a respective one of the vertical members. Each vertical member defines a respective opposite lateral side of the frame. The horizontal member comprises a depressed portion near each longitudinal end thereof. When a first such frame is stacked onto a second such frame, one depressed portion and one vertical member of the first frame respectively engage one vertical member and one depressed portion of the second frame.

1 . A scaffolding frame comprising:
 a pair of spaced apart elongated vertical members having respective top and bottom ends thereof; and   at least one elongated horizontal member mounted at each longitudinal end thereof to a respective one of said vertical members whereby each said vertical member defines a respective opposite lateral side of said frame, said horizontal member comprising a depressed portion near each said longitudinal end thereof,   wherein when a first said frame is stacked onto a second said frame, one said depressed portion and one said vertical member of said first frame respectively engage one said vertical member and one said depressed portion of said second frame.   
   
   
       2 . A scaffolding frame according to  claim 1 , wherein each depressed portion is adjacent a respective said vertical member thereby defining therewith a nesting portion at each lateral side of said frame. 
   
   
       3 . A scaffolding frame according to  claim 2 , wherein one said nesting portion at one lateral side of said first frame and one said vertical member at another lateral side of said first frame respectively engage one said vertical member at one lateral side of said second frame and one nesting portion at another lateral side of said second frame. 
   
   
       4 . A scaffolding frame according to  claim 1 , further comprising another said horizontal member, said at least one horizontal member being mounted near said respective top ends of said vertical members and said another horizontal member being mounted near said respective bottom ends of said vertical members. 
   
   
       5 . A scaffolding frame according to  claim 4 , further comprising an auxiliary vertical member mounted at a top end thereof to said at least one horizontal member and at a bottom end thereof to said another horizontal member. 
   
   
       6 . A scaffolding frame according to  claim 5 , further comprising auxiliary horizontal members mounted at one lateral end to said auxiliary vertical member and at another lateral end thereof to one of said vertical members. 
   
   
       7 . A scaffolding frame according to  claim 6 , wherein each said auxiliary horizontal member comprises an auxiliary depressed portion near each said lateral end thereof. 
   
   
       8 . A scaffolding frame according to  claim 1 , wherein said vertical members comprise respective tubular configurations. 
   
   
       9 . A scaffolding frame according to  claim 1 , wherein said horizontal member comprises a main longitudinal body having a tubular configuration. 
   
   
       10 . A scaffolding frame according to  claim 1 , wherein said horizontal member comprises a main longitudinal body said depressed portions having a size that is smaller than said main longitudinal body. 
   
   
       11 . A scaffolding frame according to  claim 1 , wherein said horizontal member comprises a main longitudinal body said depressed portions being flattened with respect to said main longitudinal body. 
   
   
       12 . A scaffolding frame according to  claim 1 , wherein said horizontal member comprises a main longitudinal body said depressed portions being beveled with respect to said main longitudinal body. 
   
   
       13 . A scaffolding frame according to  claim 1 , wherein said horizontal member comprises a main longitudinal body said depressed portions being tapered with respect to said main longitudinal body. 
   
   
       14 . A scaffolding frame according to  claim 1 , wherein said horizontal member comprises a main longitudinal body said depressed portions being recessed with respect to said main longitudinal body. 
   
   
       15 . A scaffolding frame according to  claim 1 , wherein said horizontal member comprises a main longitudinal body said depressed portions being grooved with respect to said main longitudinal body. 
   
   
       16 . A scaffold assembly comprising a plurality of scaffolding frames according to  claim 1 . 
   
   
       17 . A method of making the scaffolding frame of  claim 1 , said method comprising:
 providing two elongated vertical members;   providing at least one elongated horizontal member;   flattening a portion of the elongated horizontal member near each longitudinal end thereof; and   mounting the horizontal member at each longitudinal end thereof to a respective vertical member.
