Lift-type scaffolding

Abstract

A scaffold structure accessory is essentially comprised of a elongated, horizontal, laborer's alternate walkway and material support member having a clevis connector at its inboard end and a safety rail receptacle connector at its outboard end, a first vertical support member attached to the laborer's alternate walkway and material support member near its outboard end, a second vertical support member attached to the laborer's alternate walkway and material support member near its inboard end, and a connector on each vertical support member that co-operates with the scaffolding laborer's walkway and material support of a conventional prefabricated lift-type scaffolding module.

I claim my invention as follows:  
     
         1 . For use with a prefabricated lift-type scaffolding module having a tower structure, a carriage having an attached inwardly-projecting mason's walkway support member and attached outwardly projecting laborer's walkway and material support member, and a mason's material support member positioned above the mason's walkway support member, and a winch, pulley, and cable combination for raising and lowering the carriage and its attachments relative to the tower structure, an accessory structure comprising: 
 a horizontal laborer's alternate walkway and material support member having an inboard end and an outboard end;    a first vertical support member connected to the outboard end of said horizontal laborer's alternate walkway and material support member; and    a second vertical support member connected to the inboard end of said horizontal laborer's alternate walkway and material support member;    said horizontal laborer's alternate walkway and material support member having a connector at its inboard end for co-operation with the tower structure, said first vertical support member having a connector at its lower end for co-operation with the carriage laborer's walkway support member; and said second vertical support member having a connector at its lower end for co-operation with the carriage laborer's walkway and material support member.    
     
     
         2 . The accessory structure invention defined by  claim 1  wherein said first vertical support member has a lower end that serves as a connector by insertion into a safety rail receptacle included with the scaffolding carriage laborer's walkway and material support member.  
     
     
         3 . The accessory structure invention defined by  claim 1  wherein said second vertical support member has a lower end that is provided with an attached clevis that serves as a connector by co-operating with the scaffolding carriage laborer's walkway and material support member.
