August 7, 2014

By a News Reporter-Staff News Editor at Computer Weekly News -- A patent by the inventors Michael, Amir Meir (San Mateo, CA); Furuta, Steven J. (Santa Clara, CA); Wittig, Michael (Santa Clara, CA), filed on February 17, 2011, was published online on July 22, 2014, according to news reporting originating from Alexandria, Virginia, by VerticalNews correspondents.

Patent number 8787012 is assigned to Facebook, Inc. (Menlo Park, CA).

The following quote was obtained by the news editors from the background information supplied by the inventors: "This invention relates generally to a computer system chassis having a retention mechanism for a hard drive in the chassis.

"Conventionally, a hard drive is inserted into a hard drive housing using rails to guide the hard drive into the housing. The hard drive housing is secured to a chassis by manually securing the hard drive housing with screws. Each time a hard drive is to be removed, the hard drive housing must be unscrewed. This process can be time-consuming and cumbersome each time mounting or removal of a hard drive is required. The process can also be costly if a technician is paid for the time spent to install or remove the hard drive from the chassis. Thus, there is a need for an efficient and quick removal and retention mechanism for hard drives in computer server systems."

In addition to the background information obtained for this patent, VerticalNews journalists also obtained the inventors' summary information for this patent: "To enhance the efficiency of the installation and removal of hard drives, embodiments of the invention provide a quick and easy retention mechanism for hard drives in computer systems. The hard drive is enclosed in a hard drive housing, which is then placed on a computer chassis. The hard drive housing is equipped with one or more pins that protrude from the exterior of the housing. In some embodiments, the hard drive housing has two pins, where each pin is located on an opposite side of the hard drive housing. In other embodiments, the pins are located on the lower, back-end of the hard drive housing.

"In some embodiments, the chassis includes one or more slots for receiving the one or more pins. Each pin is coupled to a slot. In certain embodiments, the diameter of the slot is not larger than the diameter of the pin, and the friction between the pin and the slot create an interference fit, which secures the housing to the chassis.

"In another embodiment, the chassis includes a spring plunger, which aligns with an opening in the hard drive housing. The spring plunger is inserted into the opening to secure the housing to the chassis. In some embodiments, there are one or more spring plungers and one or more openings in the hard drive housing. In another embodiment, a resilient notch attached to the chassis can be used to removably secure the housing to the chassis. The resilient notch aligns with the opening in the housing to secure the housing to the chassis, and it can be easily pulled back to release the housing from the chassis."
