US Patent 6848662 Secure latching system

The disclosed system for securely latching a device in a support frame employs a pair of latching members each adapted to pivot about a latch pivot axis defined on an exterior side of the support frame and are adapted to engage a corresponding latch recess on the device downstream from the first latch pivot axis. The first and second latching members pivot toward the interior of the support frame to securely engage the respective first and second latch recesses and automatically pivot further toward the interior of the support frame within the engaged first and second latch recesses in case of an unplanned attempt to release the device from the support frame.
