Detachable crank and slider circuit pack ejector

A method for connecting a first object to a second object comprising:

• connecting a first link to the first object;
• connecting a second link to the second object;
• disposing a slot on the second link;
• disposing a pin on the first link which is releasably connectable to the slot to form a pivot connecting the first link to the second link;
• disposing an elastic device to bias the first link to a default position
• wherein the pin is releasable from the slot at a first point of travel of the pivot;
• wherein the pin is not releasable from the slot at a second point of travel of the pivot;
• wherein the first link is located between a first link pivot and the pin, and comprises a first retaining lobe partially surrounding the pin and the second link is located between a second link pivot and the slot, and comprises a second retaining lobe disposed to interlock with the first retaining lobe;
• wherein the first link pivot connects the first link to the first object, and the second link pivot connects the second link to the second object;
• wherein the first retaining lobe is disposed to interlock with the second retaining lobe at the second point of travel;
• and
• wherein the second retaining lobe is disposed to partially surround the pin at the second point of travel.

A crank-and-slider mechanism for forcing a first object toward a second object comprising:

• a crank connected to the first object;
• a connecting rod connected to the second object;
• an elastic device disposed to bias the crank to a default position;
• wherein the connecting rod is connectable to the crank by a pivot;
• wherein the first object and the second object are slidably connectable on a condition that the connecting rod is connected to the crank and the crank is rotated;
• wherein the crank is located between a crank pivot and the pivot and comprises a first retaining lobe;
• wherein the connecting rod is located between a connecting rod pivot and the pivot and comprises a second retaining lobe disposed to interlock with the first retaining lobe;
• wherein the crank pivot connects the crank to the first object, and the connecting rod pivot connects the connecting rod to the second object;
• wherein the pivot is separable at a first point of travel of the pivot;
• and
• wherein the pivot is not separable at a second point of travel of the pivot;
• wherein the first retaining lobe partially surrounds the pivot;
• and
• wherein the second retaining lobe is disposed to partially surround the pivot at the second point of travel.
