摘要：A latching structure defined by a mount, a handle pivotally mounted to themount and linked with a latch pin slidably mounted in the mount. The linkage betweenthe handle and the latch pin includes first parallel links pivotally mounted to the handleand pivotally mounted to the latch pin. Second links are pivotally mounted to the firstlinks and to a spring block slidably mounted on the latch pin. A spring is placed incompression between a shoulder on the latch pin and the spring blocks. Consequently,the linkage mechanism operates to actuate the latch pin with the handle and create anovercenter mechanism to bias the entire mechanism to either a fully opened position or afully closed position. A gasket is provided on a flange associated with the handle to sealthe latch mechanism when the mechanism is strongly biased by the spring into the closedposition.
