Patent number: 11930607Abstract: A field-replaceable unit is reversibly secured in place using two captive fasteners. Each fastener includes a telescoping knob that rotates 180 degrees in a first direction to engage a latch mechanism and rotates 180 degrees in the opposite direction to disengage the latch mechanism. The knob automatically extends when the latch mechanism is disengaged. The knob alternately extends and retracts in response to being successively pressed when the latch mechanism is engaged. The knob has two cutaways formed along outside edges to facilitate a two-finger grip for knob rotation and pulling the unit out of another module. A circular groove centered on an axis of rotation of the knob has a contrasting coloration and provides a visual and tactile indication of know location. A nub indicates rotational position of the knob.Type: GrantFiled: January 28, 2021Date of Patent: March 12, 2024Assignee: Dell Products L.P.Inventors: Amrita Sidhu Maguire, Ilhan C Gundogan, Keith C Johnson, Jason J Duquette

Patent number: 7573726Abstract: A printed circuit board module for a rack mounted chassis. The module includes a latching assembly having: a handle and a catch. When the module is inserted a predetermined distance into a chassis, the catch becomes inserted into an aperture formed on the chassis and when, at such predetermined distance, the handle is slid inwardly into the chassis, the catch engages the handle to retain the handle within the module. On the other hand if, when the module is inserted into the chassis at a distance less than the predetermined distance, the catch is unable to be inserted into an aperture and when the handle is slid inwardly from the chassis, the catch prevents the handle from being retained and such handle, when released, is urged outwardly of the module thereby indicating that the module is improperly inserted within the chassis.Type: GrantFiled: December 24, 2007Date of Patent: August 11, 2009Assignee: EMC CorporationInventors: Gerald J. Cote, Keith C. Johnson, Albert F. Beinor, Jr., Ilhan C. Gundogan, W. Brian Cunningham, Joseph P. King
