Abstract
The invention is an insulation system that enables the ice sheet of a skating rink to be economically established and maintained outdoors even at relatively high ambient temperatures. A part of the insulation system is a removable cover member that can be raised and lowered. The cover is raised to allow access to the ice and can serve much as a patio cover in this position. In the lowered position the cover forms a surface similar to a deck attached to a domestic dwelling and enables the area occupied by the ice rink to be used for other purposes when it is not being used for ice-related activities. The embodiment described is directed to residential use outdoor. The invention can be adapted for commercial use and for indoor use.

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.
