Patent ID: 7123485

Claim:
An electronic system, comprising: electronic circuitry; a power supply; and an electronic cabinet having a base, an electronic cabinet frame which extends vertically from the base and which supports electronic circuitry, and a power supply positioning assembly including: a mounting mechanism mounted to the electronic cabinet frame, a carrier which carries the power supply and which is configured to move along a vertical axis within the electronic cabinet frame, and control linkage coupled to the carrier and to the mounting mechanism, the control linkage being configured to guide movement of the carrier while the carrier moves along the vertical axis; wherein the electronic cabinet frame includes a vertical rail; wherein the carrier of the power supply positioning assembly includes a chassis which is configured to hold the power supply, and retaining members coupled to the chassis, the retaining members being configured to substantially maintain the chassis a fixed distance from the vertical rail; wherein the retaining members include rollers which substantially maintain contact with the vertical rail to prevent the chassis from moving horizontally relative to the vertical rail; wherein the power supply positioning assembly further comprises another carrier which is configured to carry another power supply and move along the vertical axis within the electronic cabinet frame while carrying the other power supply; and wherein the control linkage includes a pair of pulleys, each pulley having (i) a wheel which resides in a fixed location relative to the mounting mechanism and (ii) a cable which rides along the wheel, the cable having a first end attached to the carrier and a second end attached to the other carrier.
