Claim 12:
13. A method of operating a bolt assembly, comprising:
providing a first component including a casing; first and second sliders disposed within the casing, the first and second sliders translatable between first and second relative positions; at least one linkage coupling the first slider to the second slider, such that translation of the first slider in a first direction causes the second slider to move in a second direction different than the first direction; a first linkage arm fixedly attached at one end to the casing at a first pivot point, and pivotally attached at the other end to a lever or handle at a second pivot point; a fixed linkage arm extending at an angle proximate one end of the lever or handle, the fixed linkage arm comprising a third pivot point the lever or handle in pivotal communication with the first slider at the third pivot point, and in pivotal communication with the linkage arm at an intermediate point on the handle at the second pivot point; and one or more pliable connectors attached at one end to the second slider and at an opposing end to a bolt displaceable between extended and retracted positions, the bolt mounted to the first component and interengageable with a second component when the first and second components are in a predetermined position relative to each other and the bolt is extended;
moving the first and second components to the predetermined position;
moving the bolt to the extended position to engage the second component;
rotating the lever or handle from a first position to a second position to pivot the linkage arm about the first and second pivot points and cause the first and second sliders to translate between the first and second relative positions;
translating the third pivot point toward the first pivot point on the casing along a longitudinal axis as the lever or handle is rotated from the first position to the second position; and
applying a tension force to the one or more pliable connectors by the second slider as the second slider translates to the second relative position to retract the bolt.
