  • Patent number: 6871879
    Abstract: A fan duct assembly includes a fan duct (200), a panel (600), and a locking plate (700). One end of the fan duct defines a rectangular opening (204) with a peripheral flange (220). A pair of ribs (224) is formed on one side of the flange. A pair of L-shaped catches (602) is stamped from the panel. The catches abut against the ribs, to retain the side of the flange. The locking plate is attached to the panel opposite to the catches. The locking plate includes a base (710) and a vertical portion (720) extending from the base. An L-shaped resilient tab (730) is inclinedly stamped from the locking plate, to resiliently abut against the side of the fan duct and the flange. A pair of resilient feet (716) extends from opposite sides of the base, each foot having a free end portion resiliently abutting against the flange.

  • Patent number: 6826044
    Abstract: A computer enclosure includes a cage (10) and a drive bracket (40). The cage has two side panels (22), and each side panel forms a first slideway (26) and an aligned second slideway (30). Each first slideway includes a blocking portion (28). The drive bracket has two side walls (42). Each side wall attachingly receives a first sliding member (60), and forms a second sliding member (80). A slot (66) is defined in each first sliding member, thereby forming an elastic portion. A handle (68) is formed at a front end of the elastic portion, and a barb (72) protrudes from a top face of the elastic portion. In assembly, the drive bracket is pushed into the cage, with the second and first sliding members sliding along the second and first slideways. The barbs engage with the blocking portions, thus preventing the drive bracket from accidentally detaching from the cage.

  • Patent number: 6487070
    Abstract: A computer enclosure includes a rear panel (20) and a fastener (40) detachably and rotatably mounted to the rear panel. The rear panel defines a plurality of parallel slots (23) for receiving expansion cards (80). A pair of limbs (25) is formed on the rear panel for locking the fastener in place. The rear panel forms semi-circular pivots (21) to which the fastener is pivotally attached. The fastener is thus rotatably movable between a first position and a second position during assembly. When located at the first position, the fastener does not engage with the covers, thereby allowing the expansion card covers to be attached to or detached from the rear panel. When located at the second position, the fastener is secured to the rear panel by the limbs, and engages with the covers.
