Abstract

A vertical computer mainframe includes a front panel, a shell, a casing and diskdrive racks, etc. The diskdrive racks include an upper rack and a lower rack. The upper rack is mounted at the front end and inside the casing, and the lower rack has one side near the master board, bent into a stepped wall, defining a big chamber and a small chamber of different sizes. The lower rack may be molded from plastic as an integral part. A sliding hard diskdrive may slide into and out of the big chamber. Alternatively, the lower rack may be molded from metal as an integral part, wherein a shell is disposed in the wider chamber and the inner width of the shell is equal to the outer width of the sliding hard diskdrive. In this manner, a large amount of interior space within the computer mainframe is provided for mounting other parts or devices.

Claims

1. A structure of a vertical computer mainframe, comprising:

a casing for holding electric boards and internal parts of a computer mainframe;

a panel, including a plurality of openings for mounting diskdrives, fixed on a front side of said casing;

diskdrive mounting racks fixed on the front side and inside of said casing, at a top of said casing, wherein said diskdrive mounting racks are located so as to correspond to said openings of said panel;

wherein said diskdrive mounting racks include an upper rack and a lower rack;

wherein said upper rack may hold two 5.25 inch diskdrives or two CD-ROMs;

wherein said lower rack is integrally molded from metal, so as to define a bigger chamber and a smaller chamber, wherein a sliding hard diskdrive may be loaded in the bigger chamber and a 3.5 inch floppy diskdrive or a fixed-type hard diskdrive may be loaded in the smaller chamber; and

a shell fixed on an outside of said casing.

2. A structure of a vertical computer mainframe of claim 1, wherein a width of said bigger chamber in said lower rack is smaller than a width of said upper rack.

3. A structure of a vertical computer mainframe of claim 2, wherein a width of the bigger chamber of said lower rack is made equal to an outer width of said sliding hard diskdrive, so that said sliding hard diskdrive may be received within said bigger chamber.

4. A structure of a vertical computer mainframe of claim 2, wherein said lower rack includes a plurality of holes defined on two opposite lateral side walls thereof, wherein said holes are provided for securing a box which houses said sliding hard diskdrive.

5. A structure of a vertical computer mainframe of claim 4, wherein an inner width of said box is equal to an outer width of said sliding hard diskdrive, so that said sliding hard diskdrive may be received within said box.

6. A structure of a vertical computer mainframe of claim 1, wherein said smaller chamber of said lower rack includes two vertically spaced rows of oblong slots on two opposite side walls thereof, wherein a 3.5 inch floppy diskdrive and a fixed type hard diskdrive may be fixed at said oblong slots.

7. A structure of a vertical computer mainframe of claim 1, wherein said lower rack includes one side bent into a step-shaped wall, so as to fit around a master board of the computer machine.

8. A structure of a vertical computer mainframe, comprising:

a casing for holding electric boards and internal parts of a computer mainframe;

a panel, including a plurality of openings for mounting diskdrives, fixed on a front side of said casing;

diskdrive mounting racks fixed on the front side and inside of said casing, at a top of said casing, wherein said diskdrive mounting racks are located so as to correspond to said openings of said panel;

wherein said diskdrive mounting racks include two spaces of different sizes, defining an upper rack and a lower rack;

wherein said upper rack may hold two 5.25 inch diskdrives or two CD-ROMs;

wherein said lower rack is integrally molded from metal or plastic, defining a bigger chamber and a smaller chamber of different sizes, wherein a sliding hard diskdrive may be loaded in the bigger chamber, and a 3.5 inch floppy diskdrive or a fixed-type hard diskdrive may be loaded in the smaller chamber;

wherein said bigger chamber in said lower rack has a smaller width than a width of said upper rack;

wherein said lower rack includes a plurality of holes on two opposite lateral side walls thereof, said holes provided for securing a box of said sliding hard diskdrive, wherein a back side of said box has a connector slot for mounting a connector; and

two opposite side walls of said box, each of which has a plurality of projecting units respectively raised therefrom and corresponding to said holes on said lower rack, wherein said projecting units may slide into said holes; and

wherein two inside lateral walls of said box respectively provide a sliding trough for said sliding hard diskdrive; and

a shell fixed on an outside of said casing.

9. A structure of a vertical computer mainframe of claim 8, wherein said projecting unit of said box includes guide projections and coupling projections, wherein said guide projections are disposed near two opposite ends of the two side walls of said box and are made gradually thicker toward a middle of the guide projections, such that an outer side of said guide projections slopes outward toward an end of the side wall of said box;

wherein said coupling projections are spaced between said guide projections, and said coupling projections include hooks disposed at either side in reversed directions, wherein a thickness of said coupling projections is less than a thickness of said guide projections.

10. A structure of a vertical computer mainframe, comprising:

a casing for holding electric boards and internal parts of a computer mainframe;

a panel, including a plurality of openings for mounting diskdrives, fixed on a front side of said casing;

diskdrive mounting racks located at the front side and inside of said casing, at a top of said casing, wherein said diskdrive mounting racks are located so as to correspond to said openings of said panel;

wherein said diskdrive mounting racks include an upper rack and a lower rack having different sizes;

wherein said upper rack may hold two 5.25 inch diskdrives or two CD-ROMs;

wherein said lower rack is integrally molded from plastics, defining a bigger chamber and a smaller chamber, wherein a sliding hard diskdrive may be loaded in said bigger chamber, and a 3.5 inch floppy diskdrive and a fixed type hard diskdrive may be loaded in said smaller chamber; and

a shell fixed on an outside of said casing.

11. A structure of a vertical computer mainframe of claim 10, wherein a width of said bigger chamber in said lower rack is smaller than a width of said upper rack.

12. A structure of a vertical computer mainframe of claim 11, wherein a connector slot is defined on a back side of said bigger chamber in said lower rack, and a sliding trough is provided on a bottom of both opposite lateral sides of said bigger chamber.

13. A structure of a vertical computer mainframe of claim 11, wherein a width of the bigger chamber of said lower rack is equal to an outer width of said sliding hard diskdrive, so that said sliding hard diskdrive may be received within said bigger chamber.

14. A structure of a vertical computer mainframe of claim 10, wherein said smaller chamber of said lower rack includes two rows of oblong slots on two opposite side walls thereof.

15. A structure of a vertical computer mainframe of claim 10, wherein said lower rack has two opposite lateral sides bent into step-shaped walls.
