Abstract
Abstract A collapsible wall stud and building system which uses the wall stud is disclosed. The collapsible wall stud includes spaced inner and outer channel members that are joined to each other by pivot arms. When the collapsible wall stud is in its fully open position, wall panels can be placed between the inner and outer channel members. As the collapsible wall stud is closed, flange portions of the channel members seat in grooves in the panels thereby joining adjacent panels to form a wall section. The wall sections are placed in floor channels and are capped by top channels to which are secured suitable roof truss elements that form a roof. The collapsible wall stud facilitates the construction of a building by one unskilled in conventional building techniques.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
132 words
A collapsible wall stud and building system for use in constructing a building, said collapsible wall stud and building system comprising: a collapsible wall stud having spaced, generally parallel outer and inner channel members, said channel members being connected to each other by spaced, transverse pivot arms and movable between open and closed positions; at least first and second wall panels, end portions of said wall panels being receivable between said outer and inner channel members in said open position and being engaged by said outer and inner channel members in said closed position to form a wall section; means to secure a lower portion of said collapsible wall stud to a floor portion of the building; and means to secure a roof structure to upper positions of said collapsible wall studs.
Claim 2
Dependent Claim
132 words
A collapsible wall stud and building system for use in constructing a building, said collapsible wall stud and building system comprising: a collapsible wall stud having spaced, generally parallel outer and inner channel members, said channel members being connected to each other by spaced, transverse pivot arms and movable between open and closed positions; at least first and second wall panels, end portions of said wall panels being receivable between said outer and inner channel members in said open position and being engaged by said outer and inner channel members in said closed position to form a wall section; means to secure a lower portion of said collapsible wall stud to a floor portion of the building; and means to secure a roof structure to upper positions of said collapsible wall studs.
