Patent ID: 8035970

Claim:
A computer blade chassis comprising: a planar board; a separate slot track for supporting each of one or more computer blades in the computer blade chassis; and at least one mechanically actuated variable air flow damper mounted in the planar board, wherein the mechanically actuated variable air flow damper is mounted in a substantially same plane as one of said one or more computer blades, and wherein the mechanically actuated variable air flow damper comprises: a damper housing comprising a damper housing interior; a mechanical actuator slidably mounted at one end of the interior of the damper housing; a first damper door and a second damper door, wherein the first damper door is rotatably mounted to the damper housing by a first upper rotating pin and a first lower rotating, pin, wherein the second damper door is rotatably mounted to the damper housing by a second upper rotating pin and a second lower rotating pin; a first linear channel in the mechanical actuator, wherein the first lower rotating pin slides along the first linear channel when said one of said one or more computer blades presses against the mechanical actuator in a planar direction; a second linear channel in the mechanical actuator, wherein the second lower rotating pin slides along the second linear channel when said one of said one or more computer blades presses against the mechanical actuator in the planar direction, and wherein the first and second linear channels are substantially parallel to one another; a first transverse channel extending away from the first linear channel in a perpendicular direction; a second transverse channel extending away from the second linear channel in the perpendicular direction; a first sliding pin extending from a lower edge of the first damper door, wherein the first sliding pin is medially offset to the first lower rotating pin, and wherein the first sliding pin slides within the first transverse channel to force the first damper door to rotate and create a first opening through the interior of the damper housing when said one of said one or more computer blades presses against the mechanical actuator in the planar direction; and a second sliding pin extending from a lower edge of the second damper door, wherein the second sliding pin is medially offset to the second lower rotating pin, and wherein the second sliding pin slides within the second transverse channel to force the second damper door to rotate and create a second opening through the interior of the damper housing when said one of said one or more computer blades presses against the mechanical actuator in the planar direction.
