Patent ID: 7245499

Claim:
A board insertion/extraction mechanism, comprising: first and second handles pivotally coupled to one of a board or a board carrier frame for the board at first and second pivot points, respectively, wherein the first and second handles each include a clasp for engaging a flange when the first and second handles are rotated; and a handle coupling mechanism, connected at a first end to the first handle and connected at a second end to the second handle, wherein the handle-coupling mechanism couples the motion of the first and second handles such that moving one of the handles causes the other handle to move in an opposing direction in a similar manner, wherein the handle-coupling mechanism comprises a bar linkage pivotally coupled at a first end to the first handle at a third pivot point offset from the first pivot point and pivotally coupled at a second end to the second handle at a fourth pivot point offset from the second pivot point, wherein the third and fourth pivot points fall on opposite sides of a line drawn between the first and second pivot points at some point in time during rotation of the first and second handles.
