ABSTRACT:
An impact recovery delineation quick connect/disconnect adapter system having plate studs and a pin that when added to the impact recovery delineation system allows the delineation panel, support post and load cell to be quickly connected to and/or disconnected from the supporting base (fixed or portable) with speed and without the use of any tools. The adapter plate which is connected to the load cell provides for radially aligned slots in a recessed platform to allow the plate to engage and lock with studs that are connected to the supporting base when the load cell is rotated about its vertical axis. The studs are particularly geometrically configured and have shoulder that is larger than the barrel and a head that is larger than the shoulder which results in a mechanical locking between the plate slots and the studs upon rotation of the plate with respect to the stationary studs. A quick release detent pin passes through aligned passages in the lower load cell element adapter plate and supporting base to prevent rotation of the load cell with respect to the horizontal axis of the base after connection is achieved. This provides a positive connection that is capable of withstanding multiple high speed impact by automobile vehicles without disengaging.
