Inside the housing of a computer mainframe, device racks are fixedly secured in position for holding peripheral apparatus, for example, disk drives. These device racks need much installation space. Further, because these device racks are fixedly provided inside the housing of the computer mainframe, it is difficult to access installed peripheral apparatus for a maintenance work.
SUMMARY OF THE INVENTION
According to one aspect of the present invention, the device rack and computer mainframe housing arrangement comprises a computer mainframe housing having a front receiving hole, and a device rack pivoted to the computer housing and movable into and out of the front receiving hole between the close position and the open position, the device rack having a shell of U-shaped profile defining a plurality of vertical tracks, a front panel mounted on the shell, and a plurality of computer peripheral apparatus holders respectively inserted into the vertical tracks in the shell. According to another aspect of the present invention, the device rack and computer mainframe housing arrangement further comprises a springy retaining hook mounted in an insertion hole on the front panel and releasably hooked on an inside flange in the front receiving hole in the computer mainframe housing to secure the device rack in the close position. According to still another aspect of the present invention, the shell comprises a plurality of retaining holes above the vertical tracks thereof; the computer peripheral apparatus holders each comprise two spring plates at the respective side rails for engagement with the retaining holes on the shell, the spring plates each having a free end terminating in a finger strip, and a middle part forming a retaining portion for engagement with one retaining hole on the shell.
