Abstract

A personal computer with an upstanding structure comprises a U-shaped base frame and a support bracket, wherein the base frame constituted by a bottom plate, a front plate, and a rear plate; the support bracket is fixed between the front and rear plates of the base frame to install a conventional 51/4" floppy disk drive bracket and a power supply thereon, to install a 31/2" floppy disk drive bracket and a hard disk drive bracket thereunder. A card guide bracket which is used to install a speaker and a fan, and to guide interface cards is attached on the inner surface of the front plate of the base frame. A mother board mounting plate having a slidable snap-on fastener to secure on the support bracket is guided and positioned by a pair of guiding blocks formed on a lateral side of the bottom plate of the base frame and pushed into be secured by the snap-on fastener to a vertical disposition.

Claims

1. A personal computer with an upstanding structure comprising:

a base frame constituted by a bottom plate, a front plate and a rear plate;

a support bracket disposed and secured between said front and rear plates of the base frame, said support bracket having an upper side and an under side;

a 51/4" floppy disk drive bracket disposed and secured on the upper side of said support bracket and in contact with said front plate;

a power supply disposed and secured on the upper side of said support bracket and in proximity to said rear plate;

a 31/2" floppy disk drive bracket disposed on the under side of said support bracket and a front edge thereof secured to said front plate;

a hard disk drive bracket releasably disposed and secured on the under side of said support bracket and in proximity to said rear plate;

a card guide bracket releasably disposed and secured on an inside surface of said front plate and below said 31/2" floppy disk drive bracket; and

a mother board mounting plate which is upstanding and is disposed between said support bracket and said bottom plate.

2. A personal computer as claimed in claim 1, wherein said support bracket has a pair of hangers on the under side thereof, and said 31/2" floppy disk drive bracket has a plurality of hook-like members corresponding to said hangers so that said 31/2" floppy disk drive bracket is slidably with respect to said support bracket and fixed thereon with said hook-like members engaging with said hangers.

3. A personal computer as claimed in claim 1, wherein said support bracket has a pair of hangers and a slot therebetween on the under side thereof, and said hard disk drive bracket has a plurality of hook-like members corresponding to said hangers and a resilient snap catch corresponding to said slot so that said hard disk drive bracket is slidable with respect to said support bracket and fixed thereon with said hook-like members engaging with said hangers and said hard disk drive bracket is secured on said support bracket with said resilient snap catch engaging said slot.

4. A personal computer as claimed in claim 1, wherein said support bracket has a pair of hook-like members formed on the upper side thereof to respectively hook on a corresponding slit formed on flange of said power supply so as to secure said power supply.

5. A personal computer as claimed in claim 1, wherein said card guide bracket has a plurality of openings to be respectively hooked on by a corresponding hook-like member disposed on said inside surface of the front plate and a pair of resilient plates each having a knobble thereon being disposed on said card guide bracket to respectively engage with a corresponding positioning slot formed on said front plate.

6. A personal computer as claimed in claim 1, wherein said mother board mounting plate has a slidable fastener disposed on one side and in proximity to a top edge thereof which is close to said support bracket, said slidable fastener being spring-based to engage with a counterpart retaining means disposed on said support bracket and a bottom edge of said mother board mounting plate opposite to said top edge is disposed and fixed between at least one combination of gripper and positioning block disposed on said bottom plate, whereby said mother board mounting plate is upstanding between said support bracket and said bottom plate.

7. A personal computer as claimed in claim 6, wherein said slidable fastener is a U-shaped member comprising a horizontal section and two vertical sections, of which each of the vertical section is guided by guiding means and attached to said mother board mounting plate with an extension spring so as to be slidable with respect to said guiding means.

8. A personal computer as claimed in claim 7, wherein each of said vertical sections has lugs protruding from the end thereof and said counterpart retaining means is holes in said support bracket corresponding to said protruding lugs so as to respectively receive said protruding lugs therein to secure said mother board mounting plate.
