Abstract
A non-handed shock arrestor is provided for pivotally mounted doors, and it includes a frame member with a pivot plate portion with pivot apertures adjacent either end thereof, and it is disposed horizontally on the door frame with one of its pivot apertures aligned with the hinge pins. The frame member also has a mounting portion extending perpendicularly to the pivot plate portion with apertures therein seating fasteners which secure the frame member to the face of the door frame. The arrestor also includes a door member with a pivot plate portion with pivot apertures adjacent either end thereof aligned with those of the frame member, and disposed horizontally of the door. It extends over the hinges. The door member also has a mounting portion intermediate the ends of the pivot plate portion extending perpendicularly thereto, and having apertures therein seating fasteners securing the door member to the face of the door. A pivot member is seated in an aligned pair of the pivot apertures to provide a pivotal connection between the frame and door members, and it is aligned with the pivot axis of the hinges of the door assembly. The pivot member is also mountable in the other of the aligned pair of pivot apertures for a door of the opposite hand.

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.
