Patent number: 6826056Abstract: Systems for mounting data storage devices to a chassises are provided. A representative system includes a filler carrier that incorporates a bezel. The bezel including a first snap configured to move between a latched position and an unlatched position. In the latched position, the snap facilitates secure mounting of the filler carrier to a chassis by forming an interference fit with the chassis. In the unlatched position, the snap facilitates removal of the filler carrier from the chassis. The bezel of the filler carrier can be formed as a monolithic structure. Other systems and devices also are provided.Type: GrantFiled: June 4, 2003Date of Patent: November 30, 2004Assignee: Hewlett-Packard Development Company, L.P.Inventors: Brian S. Tsuyuki, Pete Capano, Darrel W. Poulter, Herbert J. Tanzer

Patent number: 6317329Abstract: A data storage module alignment system and method for use in a data storage module and enclosure system including a module enclosure having a plurality of bay slots and at least one data storage module. The data storage module alignment system comprises at least one alignment guide that is adapted to be mounted at the module enclosure entrance and at least one guide rail that is adapted to be mounted to the data storage module. The alignment guide includes a plurality of guide channels having rounded edges. The guide rail is sized and shaped for receipt within the guide channels. Typically, the alignment guide further includes a plurality of guide flanges that are arranged asymmetrically along the alignment guide. The inner side of each guide flange defines an edge of one of the guide channels and includes chamfers which facilitate initial alignment of the data storage module within one of the bay slots of the module enclosure.Type: GrantFiled: November 13, 1998Date of Patent: November 13, 2001Assignee: Hewlett-Packard CompanyInventors: James L.

Patent number: 5575529Abstract: Device modules of an electrical system are slidably fitted in an enclosure and integrated therein as a part of an air duct system for cooling the modules. Other modules such as air mover modules, for the air duct system, are also slidably fitted in the enclosure to move air in the air ducts and the device modules. Each module carries a pivotally mounted flat latch lever in a recess in a surface at one end of the module. A latch member on one end of the latch lever engages a catch member on the enclosure as the module approaches its fully inserted position. Movement of the latch lever to latched position, when the latch member and catch member are engaged, pivots the latch lever about the catch member and applies force to the module at the pivotal mount, to drive the module into its fully inserted position. The mechanical advantage provided by the latch lever minimizes the manually applied forces acting on the module which significantly reduces the likelihood of damaging any device within the module.Type: GrantFiled: February 14, 1995Date of Patent: November 19, 1996Assignee: Hewlett-Packard CompanyInventors: James L. Dowdy, Darrel W. Poulter

Patent number: 5520069Abstract: A lever mechanism for the insertion and removal of a module in a housing includes two levers the proximal ends of which are pivotally mounted to the module at spaced locations on the module. The distal ends of the levers are disposed in confronting relationship when the levers are longitudinally aligned. A leaf spring is longitudinally slidably mounted to the levers including sliding attachment to the levers at their distal ends. The leaf spring is sufficiently stiff to maintain spatial alignment of the distal ends of the levers during angular movement. Arcuate sectors branching from the levers adjacent their distal ends overlap and provide handles for manually operating the levers. Latches correspondingly positioned at the proximal ends of the levers cooperate with catches in the opening or slot in the housing in which the module is inserted to provide the final insertion or removal forces for insertion and removal of the module with respect to the housing.Type: GrantFiled: October 31, 1994Date of Patent: May 28, 1996Assignee: Hewlett-Packard CompanyInventors: Rudolf R. Rynders, Darrel W. Poulter

Patent number: 5493474Abstract: For cooling a plurality of device modules mounted in an enclosure, a redundant air moving system is coupled to the air duct system of the enclosure. The redundant air moving system has two, three, or more air movers. If one air mover fails, the remaining air mover(s) still provide the required air volume rate for adequate cooling. To make the air movers redundant, they are coupled in parallel to a common air plenum in the air duct system from which ducting to all devices to be cooled is provided. In case of an air mover failure, a flapper door is built into the exhaust path of the air mover. The flapper door is pendulously pivoted in the exhaust path. It is held open by exhaust air flow and is closed by gravity upon cessation of exhaust air flow and held closed by reverse air pressure for the purpose of preventing reverse air flow in the exhaust path, which would disrupt the air pressure in the air plenum and consequently also in the air duct system.Type: GrantFiled: February 14, 1995Date of Patent: February 20, 1996Assignee: Hewlett-Packard CompanyInventors: Guenter Schkrohowsky, James L. Dowdy, Darrel W. Poulter

Patent number: 5477416Abstract: An enclosure for cooling device modules has metered air passages in an air duct system. The device modules which are of the form of air ducts are inserted into the air duct system of the enclosure and have exhaust air passages which are coupled to metered air passages in the air duct system of the enclosure. A source of reduced air pressure which is coupled to the air duct system of the enclosure draws air through the device module into the air duct system of the enclosure via the exhaust air passage of the device module and the metered air passage of the air duct system.Type: GrantFiled: February 14, 1995Date of Patent: December 19, 1995Assignee: Hewlett-Packard CompanyInventors: Guenter Schkrohowsky, Cliff Harrison, Darrel W.
