Components for assembling scaffolding system

Abstract

A kit for constructing scaffolding using standard lumber sizes and brackets which are pinned to the lumber pieces so the scaffolding can be rapidly broken down by removing the pins.

What is claimed is:  
     
         1 . A kit for constructing scaffolding using pieces of lumber of standard sizes, comprising: 
 a) a plurality of right angle brackets, each comprising a first hollow sleeve for slidably receiving a first piece of lumber and a second hollow sleeve secured at right angles to said first hollow sleeve for slidably receiving a second piece of lumber, a pin associated with each of said first and second hollow sleeves, said first and second hollow sleeves being each provided with a hole for receiving said pin;    b) a plurality of base elements each comprising a third hollow sleeve for slidably receiving an end of a piece of lumber, a ground-engaging element connected to said third hollow sleeve, and a pin, wherein said third hollow sleeve is provided with a hole for receiving said pin; and    c) a plurality of bracing elements for bracing against a vertical surface, each comprising a fourth hollow sleeve for slidably receiving an end of a piece of lumber, a surface-engaging element connected to said fourth hollow sleeve, and a pin, wherein said fourth hollow sleeve is provided with a hole for receiving said pin.    
     
     
         2 . The kit for constructing scaffolding of  claim 1  further comprising a plurality of pieces of lumber of standard lumber sizes, adapted to be secured in said hollow sleeves by providing holes in said lumber for receiving each of said pins.  
     
     
         3 . The kit for constructing scaffolding of  claim 3  further comprising cotter pin means for securing each of said pins in said holes.  
     
     
         4 . The kit for constructing scaffolding of  claim 1  wherein said plurality of bracing elements are adapted to bear against a vertical wall.  
     
     
         5 . The kit for constructing scaffolding of  claim 1  wherein said plurality of bracing elements are adapted to bear against a fascia plate.  
     
     
         6 . The kit for constructing scaffolding of  claim 3  further comprising support bracket means comprising a channel sized to seat on an edge of a piece of lumber, and means for securing said channel to an underside of a piece of lumber.  
     
     
         7 . A right angle bracket for use in erection of scaffolding, wherein said scaffolding is erected using a plurality of lumber pieces of pre-determined standard cross-sectional dimensions, said bracket comprising a first hollow sleeve sized to slidably receive a first of said pieces of lumber, a second hollow sleeve secured at right angles to said first hollow sleeve for slidably receiving a second of said pieces of lumber, and a pin associated with each of said first and second hollow sleeves, said first and second hollow sleeves being each provided with a hole for receiving said pins.  
     
     
         8 . The right angle bracket according to  claim 7  wherein said first and second sleeves are made of metal.  
     
     
         9 . The right angle bracket according to  claim 8  wherein said first and second sleeves are secured by welds.  
     
     
         10 . The right angle bracket according to  claim 7  wherein said first and second sleeves are rectangular in cross-section.  
     
     
         11 . A scaffold structure comprising: 
 a) at least two right angle brackets as claimed in  claim 7;     b) at least two vertical support elements each comprising a standard sized piece of lumber slidably received in each of said first hollow sleeves of said right angle brackets;    c) at least two horizontal support elements each comprising a standard sized piece of lumber slidably received in each of said second hollow sleeves of said right angle brackets;    wherein each of said vertical and horizontal support elements is provided with a hole for receiving one of said pins.    
     
     
         12 . The scaffold structure of  claim 11  further comprising a base element comprising a third hollow sleeve for slidably receiving an end of a piece of lumber, a ground-engaging element connected to said third hollow sleeve, and a pin, wherein said third hollow sleeve is provided with a hole for receiving said pin  
     
     
         13 . The scaffold structure of  claim 11  further comprising a bracing element for bracing against a vertical surface secured to an end of one of said horizontal support elements, said bracing element comprising a fourth hollow sleeve for slidably receiving said end of a piece of lumber, a surface-engaging element connected to said fourth hollow sleeve, and a pin, wherein said fourth hollow sleeve is provided with a hole for receiving said pin.  
     
     
         14 . The scaffold structure of  claim 11  further comprising at least two support bracket means each comprising a channel seated on an edge of one of said horizontal support elements, and a piece of lumber secured to said channel by said securing means to an underside of a piece of lumber.  
     
     
         15 . The scaffold structure of  claim 11  wherein each of said pins is secured in said holes by cotter pin means.  
     
     
         16 . The scaffold structure of  claim 13  wherein said bracing element is adapted to bear against a vertical wall.  
     
     
         17 . The scaffold structure of  claim 13  wherein said bracing element is adapted to bear against a fascia plate.
