US Patent 11337332 Latch with auto-close

A latch includes a pin held in a set position by a trigger. The trigger, when depressed, allows the pin to extend from a chassis and engage a rack, preventing the chassis from being removed from the rack. A handle allows the pin to be retracted, with a reset catch maintaining the pin in the retracted position. The trigger, when released, dislodges the reset catch and the pin returns to the set position maintained by the trigger.
