Patent ID: 7850260

Claim:
An injection/ejection mechanism for mounting and dismounting of a unit to a chassis, the mechanism comprising a unit having a drive screw that cooperates with a threaded barrel, the threaded barrel being rotatable for engagement and disengagement with at least one component of a chassis and the drive screw being rotatable in a first rotational direction to urge the threaded barrel in a first longitudinal direction against the at least one component of the chassis for mounting of the unit and being rotatable in an opposite rotational direction to urge the threaded barrel in an opposite longitudinal direction against the at least one component of the chassis for dismounting of the unit; wherein the unit includes a set of connectors that connect to corresponding connectors that are coupled to the chassis; wherein rotation of the drive screw in the first rotational direction is operable to urge the threaded barrel in an outward direction against the at least one component of the chassis to draw in the unit with respect to the chassis, causing the connectors for the unit to connect to the corresponding connectors that are coupled to the chassis.
