Patent ID: 7684209

Claim:
A computer system, comprising: a housing; a backplane coupled to the housing; and at least one floor plate comprising an engagement assembly to connect a printed circuit board assembly to the backplane, wherein the engagement assembly utilizes a single mechanical force lever to secure the printed circuit board assembly to the backplane, wherein: the mechanical force lever is connected to the floor plate and rotatable between a first position and a second position; the engagement assembly comprises: a linkage arm connected to the mechanical force lever; a pin plate connected to the linkage arm and to the floor plate, and rotatable between a first position and a second position: the floor plate comprises a first slot; the pin plate comprises a first pin that extends through the first slot in the floor; a printed circuit board assembly; wherein: the mechanical force lever comprises a second pin; the printed circuit board assembly comprises a second aperture through which the second pin extends when the printed circuit board assembly is mounted onto the floor plate; and wherein rotating the mechanical force lever between the first position and the second position drives the first pin between a first position in the first slot and a second position in the first slot, thereby driving the printed circuit board assembly between a first position on the floor and a second position on the floor plate.
