Abstract:

A double acting service traffic door latch system embodiment of the present invention comprises a dual electro-mechanical lock in a single housing that is surface installed in the overhead door casings horizontally just over two bi-swing tandem warehouse security doors. Each electro-mechanical lock has two catches that drop down with a pivot arm onto either side of its respective door to prevent that door opening in either direction. A flat thin-profile housing allows the lock assembly to fit in between the tops of existing doors and their header. The doors can freely swing open if the respective catches retract back into the housing. Wireless RFID readers are used to unlock the doors when authorized users approach and are recognized. The lock is failsafe in that losing power will always unlock the doors immediately.

Abstract:

A hydraulic closer and dampener that can be removed and replaced by opening a post cap to then lift an internal closer assembly out of the top of an internally pivotable shaft inside a free-standing floor-mounted post. The remainder of the gate mechanism remains functional during such service. An automatic closing speed adjustment is easy to access and set. There are no external hinges, the gate pivots on an axis coaxial to the cylindrical post.
