Securing device of computer data storage

A computer enclosure comprising a chassis in which a securing device is mounted adapted to releasably secure a data storage device to the chassis, the securing device comprising:

• a support frame fixed in the chassis adapted to support the data storage device thereon, the support frame comprising a top wall above which the data storage device is positioned;
• projections adapted to be mounted to the data storage device;
• and
• a control bar movably attached below the top wall of the support frame to be movable between a released position and a locked position, notches being defined in the control bar through which the corresponding projections pass when the control bar is at the released position, first retention means being formed on the control bar for retaining the projections and thus securing the data storage device in position when the control bar is at the locked position.

An enclosure assembly comprising:

• a chassis;
• a support frame fixed to said chassis and including a top wall with therein at least a slot in a front-to-back direction;
• a data storage device attached to said support frame until being completely seated atop said top wall with a projection formed on a bottom surface thereof and moving along and extending through said slot so as to restrain movement of the data storage device with regard to the support frame in a horizontal side-to-side direction, said projection forming an expanded end cooperating with the bottom surface of the data storage to sandwich the supporting wall therebetween so as to restrain movement of the data storage device with regard to the support frame in an up-and-down direction;
• and
• a control bar slidably, with a limited range, attached under the top wall of the support frame along said side-to-side direction and defining a retention means thereof;
• wherein
• when said control bar is at a released position, the data storage device is allowed to be moved with regard to the support frame in said front-to-back direction;
• when the control bar is at a locked position, said retention means restrains movement of the data storage device with regard to the support frame in both forward and rearward directions.
