ABSTRACT:
CLAIM OF PRIORITY
This application makes reference to, incorporates the same herein, and claims all benefits accruing under 35 U.S.C. § 119 from an application entitled Apparatus For Mounting Parts And Personal Computer Equipped With The Same earlier filed in the Korean Industrial Property Office on May 15, 1997, and there duly assigned Serial No. 97-18654 by that Office.
FIELD OF THE INVENTION
The present invention relates to, in general, an apparatus for mounting parts to computers and a personal computer equipped with the same and, more particularly, to an apparatus capable of easily and detachably mounting the parts of a computer, for example, a speaker, indicator board and option card, to the main frame of a desktop personal computer using a single body, thus effectively increasing the usable space defined in the main frame of the computer and achieving an improved mounting performance.
DESCRIPTION OF THE RELATED ART
As well known to those skilled in the art, additional option cards may be detachably mounted to a desktop personal computer so as to provide an upgraded function and large capacity to a personal computer.
Recently, auxiliary devices, such as CD-ROM (compact disk read only memory) drives and DVD (digital video disk) drives, have been incorporated in personal computers, in order to output data through a display unit, such as moving picture data and audio data as well as character data. In a desktop personal computer exemplary of contemporary practice in the art, a main body of a personal computer comprises a main frame. Both an option board and a mother board are detachably installed in the main frame. In practice, the mother board, having a circuit part designed for controlling the operation of the computer, is detachably installed to the bottom surface of the main frame. The option board includes a plurality of extended slots, which are designed for allowing a plurality of option cards to be selectively and detachably installed.
In order to mount the option cards to the extended slots of the computer, a support bracket has to be mounted in the main frame at a desired position. That is, since the support bracket correctly guides and supports option cards fitted in the extended slots, the option cards are effectively connected to the extended slots.
In addition, a speaker is detachably mounted to the front wall of the main frame. The mounting of the speaker may be achieved using a separate bracket designed for mounting the speaker. Alternatively, the speaker may be directly mounted to the main frame using screws. An indicator board, designed for allowing a user to recognize the “ON” or “OFF” state of electric power or the operation of a hard disk drive, is detachably installed at the front wall of the main frame using an additional bracket.
However, the above-mentioned desktop personal computer of the exemplary art is problematic in that a plurality of brackets or support members are mounted to the main frame and are required so as to mount desired elements, for example, a speaker, indicator board and option card, to the main frame, thus reducing the usable space defined in the main frame and the production efficiency of component assembly in the desktop personal computer.
U.S. Pat. No. 5,448,495 to Liu entitled Multifunctional Frame Assembly With Fan And Speaker For A Personal Computer discloses a multifunctional frame assembly for personal computer including a multifunctional frame having a speaker-engaged portion and fan-engaged portion, with the speaker-engaged portion having a pair of engaging members which define an opening. It is disclosed that the fan-engaged portion has a surface with an orifice and a pair of stoppers each being provided with a pair of engaged hooks extending longitudinally and a pair of ribs on an inner wall of the stopper. It is disclosed that a speaker is clamped between engaging members and in alignment with the opening. A ventilating fan with a plurality of holes at the corner region thereof is installed between the ribs and in alignment with the orifice. It is disclosed that a chassis of the computer having an end plate is provided with engaged holes corresponding to the engaged hooks of the stoppers, wherein the frame can be positioned by engaging the engaged hooks with the corresponding engaged holes on the end plate. It is further disclosed that a rear surface of the frame is provided with at least a pair of guiding blocks, each pair of guiding blocks defining a slot therebetween so as to provide auxiliary support for interface cards. It is also disclosed that while the interface cards are inserted onto the motherboard, one end of each interface card is inserted into a slot defined by a pair of guiding blocks.
U.S. Pat. No. 5,062,016 to Zupancic entitled Set of Structural Brackets That Allow Electronic/Electrical Assemblies to Be Mounted Within A Computer Enclosure, discloses a method that allows a disk-drive/controller card mounting bracket and a slotted hang bracket to increase the overall power and efficiency of a computer, whereby the bracket is used to mount a 3.5-inch Winchester drive and its controller interface card to form a complete assembly. It is disclosed that the bracket allows one or more circuit card assemblies or electrical equipment, such as a cooling fan or disk drive to be mounted in a cantilever fashion within a computer.
U.S. Pat. No. 5,224,024 to Tu et al. entitled Retaining Frame For Components Of A Personal Computer, discloses a retaining frame for components of a personal computer having a horizontal portion, with a first section and a second section connected together, and a vertical portion attached substantially perpendicular to the first and second sections. It is disclosed that the first section is adapted to secure a disk drive holder and has at least one leg extending downward to support the retaining frame, with the second section being adapted to secure a power supply, and having at least one leg extending downward to support the retaining frame. It is disclosed that the vertical portion includes a speaker seat and a ventilation fan seat at a central location near the first section, and a speaker securing rib and fan securing device, respectively, for fastening a speaker and a ventilation fan. It is disclosed that the retaining frame with a disk drive holder, power supply, speaker and ventilation fan mounted thereon is disposed on a lower portion of a computer case, and secured inside the case by a vertical force exerted on the retaining frame by an upper portion of the computer case.
U.S. Pat. No. 5,269,598 to Liu entitled Personal Computer Component Support Structure, discloses a personal computer component support structure having a base casing having a front plate and a back plate with a main frame secured therebetween. It is disclosed that the main frame comprises a front portion defining therein a two-staged interior space for respectively receiving a 5¼ inch floppy disk drive and a 3½ inch floppy disk drive and a rear portion defining therein a second interior space for receiving at least one hard disk drive. It is disclosed that a holder member for supporting a ventilation fan and a speaker is secured on an inside surface of the front plate of the base casing.
U.S. Pat. No. 5,278,730 to Kikinis entitled Modular Notebook Computer Having A Planar Array Of Module Bays and U.S. Pat. No. 5,331,509 to Kikinis entitled Modular Notebook Computer Having A Planar Array Of Module Bays And A Pivotally Attached Flat-Panel Display, disclose a modular notebook computer having a framework with module bays for receiving CPU modules, power modules, and peripheral function modules such as floppy and hard disk drives. It is disclosed that the framework has a built-in compressed bus and a variety of function modules which can be plugged into any one of the module bays, with the function modules including, but not limited to, CPU, power, floppy disk, hard disk, RAM memory, LAN communication, modem, FAX communication, and data acquisition.
