Abstract
A latch mechanism includes a handle connected to a pin by a linkage. The linkage converts rotation of the handle relative to a frame into axial movement of the pin between extended and retracted positions relative to the frame. The pin engages with a pre-load adjustment mechanism in the extended position to apply a pre-load through the linkage that biases the pin toward the extended position. The pre-load adjustment mechanism is adjustable to set the pre-load through the linkage to a predetermined value as selected by a user.
