Abstract
A lock mechanism within a slot of a computer chassis is disclosed. The lock mechanism includes a gear wheel, a gear rack body, a push rod latch, a push rod body, and a chassis latch. The gear wheel, the gear rack body, the push rod latch, the push rod body, and the chassis latch cooperate to restrict a flap in the slot from opening when the flap is in the closed position, and the chassis latch is engaged with a cutout on the push rod body.
Claims20
A lock mechanism within a slot of a computer chassis comprising:
- a gear wheel coupled to a flap within the slot, the flap being configured to restrict airflow through the slot;
- a gear rack body meshed with the gear wheel and configured to translate within the slot, the gear rack body having a gear rack projection;
- a push rod latch configured to translate within the slot, the push rod latch including a push rod latch projection aligned to abut against the gear rack projection;
- a push rod body configured to translate within the slot and abut against the flap for rotating the flap between an open position and a closed position, the push rod body including a cutout at a first end;
- and
- a chassis latch configured to engage the cutout of the push rod body,
- wherein the gear wheel, the gear rack body, the push rod latch, the push rod body, and the chassis latch cooperate to restrict the flap from opening when the flap is in the closed position and the chassis latch is engaged with the cutout.

A computer system comprising:
- a sled configured to retain a computer component;
- a chassis having a slot configured to accept the sled as the sled translates into the chassis;
- a flap configured to restrict airflow through the slot in a closed position and allow airflow through the slot in an open position;
- and
- a lock mechanism in the slot comprising:
- a gear wheel coupled to the flap;
- a gear rack body meshed with the gear wheel and configured to translate within the slot, the gear rack body having a gear rack projection;
- a push rod latch configured to translate within the slot, the push rod latch including a push rod latch projection aligned to abut against the gear rack projection;
- a push rod body configured to translate within the slot and abut against the flap for rotating the flap between the closed position and the open position, the push rod body including a cutout at a first end;
- and
- a chassis latch configured to engage the cutout of the push rod body when the sled is not inserted into the slot,
- wherein the chassis latch is engaged with the cutout with the flap in the closed position and the push rod latch projection abuts against the gear rack projection to prevent the gear wheel, through the gear rack body, from rotating, which locks the flap in the closed position.
