Abstract
A portable activity floor comprised of a plurality of separate panels that can be readily and selectively interlocked together into a finalized configuration. Each panel has an underlayment providing a core with spaced stringers fastened to the underside thereof. Elongated finishing strips mounted on the upper surface of the underlayment form the outer surface of the panel. In one type of floor assembly, alternate strips are longer than their adjacent strips at the inner side of each panel to form laterally spaced interlock fingers. A pair of hinge members pivotally connects adjacent panels to one another and allows them to be relatively pivoted on a fixed axis with finger interlock alignment accuracy from an initial connected position to a fully assembled position in which the fingers of the finishing strips closely mesh and interlock. Further, the hinge members when connected prevent lateral movement of adjacent panels. This allows the hinge assembly to be used with many types of floors, such as in addition to floors with interlock fingers, square edge floors, square end floors and parquet floors.

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.
