Abstract
A retention-extraction device is provided for a removable card in a chassis. The device includes an actuation rod having a cam slot, the actuation rod configured to provide linear movement along the length of the actuation rod, and an extraction lever operatively connected to a proximal end of the actuation rod and pivotally secured to the chassis. The device also includes a bell crank with a cam follower that is configured to ride in the cam slot and a latch hook that pivots between an open and closed position based on the motion of the bell crank. The linear movement of the actuation rod causes the extraction lever to apply a force to a portion of the card and causes the latch hook to pivot to an open position to allow removal of the card.
