DOOR CLOSURE NOISE DAMPENING SYSTEM WITH AUTO DEADBOLT DOOR LOCK
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.
