Abstract
A modular wall system including a plurality of wall panels removably attached between a floor and a ceiling by a head track assembly and a floor track assembly respectively. The wall panels include a core material covered on each face by a thin metal skin and are of sufficient strength and rigidity to allow their placement between the head and floor track assemblies without the requirement of stud members or the like. The head track and the floor track assemblies both comprise gasket elements which prevent the passage of microcontamination around the panel members, and the side surfaces of each panel member contains a gasket which abuts and seals against an adjacent panel member to prevent the flow of microcontaminants around the sides of the panel. The floor track assembly also comprises a fastening member which securely holds the bottom of the wall panel to prevent relative movement therewith. The floor track assembly also includes alignment screws which allow the floor track to be leveled, regardless of the unevenness of the floor it is placed upon, thereby insuring automatic alignment of the well panels when placed thereon and insuring complete sealing between adjacently mounted panels. The floor track assembly can also include a U-shaped cradle which allows for more secure attachment of the floor track assembly to the floor. The present wall system can be used for cleanroom construction, or may be used for other types of construction such as office space or the like.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
