Abstract
A locking mechanism comprising a linkage assembly comprising a first link and a second link joined at a pivot point; a linkage assembly spring to bias the linkage assembly into a first, locked, position; a cam assembly having a cam 1 with a cam surface in engagement with the linkage assembly; a cam biasing member such as a spring arranged to bias the cam surface to press against the linkage assembly sufficiently to overcome the linkage assembly spring and to force the linkage assembly into a second, unlocked position; and a solenoid assembly arranged to engage the cam in a locked position in which the cam is prevented from forcing the linkage assembly into the unlocked position.
