Patent ID: 7292456

Claim:
A control assembly for controlling removal of a circuit board from a chassis, the control assembly comprising: a support member constructed and arranged to fasten to the circuit board; a handle pivotally attached to the support member, so as to allow the handle to swing from an opened position to a closed position relative to the support member during installation of the circuit board within the chassis, and from the closed position to the opened position during removal of the circuit board from the chassis; a button operatively connected to the handle and moveable between a biased position and, a depressed position relative to the support member, the button (i) inhibiting removal of the circuit board from the chassis when the support member is fastened to the circuit board and the button is in the biased position relative to the support member by preventing pivoting of the handle, and (ii) enabling removal of the circuit board from the chassis when the support member is fastened to the circuit board and the button is in the depressed position relative to the support member by allowing pivoting of the handle: a mounting portion constructed and arranged to engage the button and the handle, the mounting portion including a slot having a first end and a second end disposed therein; a pin disposed within the handle and the slot, the pin being moveable within the slot from a first position within the slot to a second position within the slot to allow pivotal movement of the handle from a closed to an open position; and wherein the biased position of the button retains the pin in the first position and prevents movement of the pin to the second position within the slot so as to prevent pivotal movement of the handle, the pin being moveable to the second position within the slot upon depression of the button so as to allow pivotal movement of the handle.
