Abstract
A system for ensuring that a door automatically closes and latches while simultaneously ensuring that it does so in a manner which either eliminates or significantly minimizes the amount of noise such closure causes while making sure that the door does in fact fully close and latch. A door mounted portion includes a piston attached to a pivotable arm having a wheel on the end of the arm configured to engage with a doorframe mounted portion to slow the travel of the door into the doorframe while pulling the door into the doorframe to ensure secure closure of the door. A doorframe mounted striker plate portion is configured with at least one spring-loaded striker damper or flap against which a door latch and/or automatically deploying deadbolt lock engages, to slow the engagement of the door latch or deadbolt with striker region in the frame to minimize noise.

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.
