## Background
This application is related to a copending application, application Ser. No. 11/672,963, entitled with “MOUNTING DEVICE FOR DISK DRIVE”, assigned to the same assignee.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to mounting apparatuses, and more particularly to a mounting apparatus for a data storage device of a computer system.
2. Description of Related Art
A typical personal computer comprises data storage devices such as a hard disk drive (HDD), a floppy disk drive, and a compact disc read-only memory (CD-ROM) drive. Conventionally, the data storage devices are attached to a chassis of a computer enclosure using screws. A tool such as a screwdriver is required to fasten the screws when installing the data storage devices, and to unfasten the screws when removing the data storage devices. The operations are laborious and time-consuming. Furthermore, even careful operators may cause the tool to slip, or may drop screws. When this happens, other internal components of the computer may be damaged.
Nowadays, to allow convenient installation of a data storage device in a computer system, a pair of rails is typically provided. The rails are assembled to a pair of sidewalls of the data storage device, and then together inserted into a bracket of the computer system, between a pair of side plates of the bracket. However, the rails will increase space between the sidewalls of the data storage device and the side plates of the bracket, thereby reducing EMI-proofing (Electro Magnetic Interference, EMI) capability of the computer system.
What is needed, therefore, is a mounting apparatus with a simple structure for convenient installation and removal of a data storage device of a computer system.
SUMMARY OF THE INVENTION
A mounting apparatus for a data storage device with securing holes defined therein, includes a base and a pivot member pivotally attached to the base. The base includes a bottom panel and a first side panel with at least a securing piece corresponding to the securing hole of the data storage device extending therefrom, and a clip. A pivot post protrudes from the bottom panel of the base. The pivot member includes a flange panel and a second side panel with at least a securing piece corresponding to the securing hole of the data storage device extending therefrom, a pivot hole corresponding to the pivot post of the base, an opening corresponding to the clip of the base being defined in the flange panel, and at least a securing piece corresponding to the securing hole of the data storage device extending from the second side panel. The clip of the base engages into the opening of the pivot member when the pivot member rotates to a locked position, thus the data storage device is mountable between the first side panel and the second side panel. The clip of the base disengages from the opening of the flange panel of the pivot member when the pivot member rotates to an unlocked position.
Other advantages and novel features will be drawn from the following detailed description of preferred embodiments with attached drawings, in which:

DETAILED DESCRIPTION OF THE INVENTION
Referring to FIG. 1, a mounting apparatus of a preferred embodiment of the present invention is configured for securing a data storage device 50. A pair of securing holes 52 is defined in each of two sidewalls of the data storage device 50. In this preferred embodiment, the mounting apparatus includes a mounting bracket 40 for receiving the data storage device 50 therein, and a chassis 10 for accommodating the mounting bracket 40 and the data storage device 50 therein. The mounting bracket 40 includes a base 20 and a pivot member 30 pivotally attached to the base 20.
The chassis 10 includes a bottom panel 12 with a plurality of fixing portions 121 and bulges 123 extending upwardly therefrom.
The base 20 of the mounting bracket 40 includes a bottom panel 22 and a first side panel 24 perpendicularly extending from a side edge of the bottom panel 22. A plurality of T-shaped openings 221 corresponding to the fixing portions 121 are defined in the bottom panel 22 of the base 20, the openings 221 each include a bigger entrance portion and a smaller securing portion. A cantilever resilient piece 223 perpendicular to the first side panel 24 extends from a center portion of the bottom panel 22 to another side of the base 20. A clip 2231, such as a barb, is formed on a free end of the resilient piece 223. A height of the bulge 123 of the chassis 10 is higher than that of the clip 2231 of the resilient piece 223 of the base 20. A pivot post 225 protrudes upwardly from an edge away from the first side panel 24 near a corner of the bottom panel 22 of the base 20. An inverted L-shaped catch 227 extends upwardly from the edge at an opposite corner of the bottom panel 22 of the base 20. A short arc-shaped slot 229 is defined in the bottom panel 22 of the base 20 between the catch 227 and the post 225. A center of the arc-shaped slot 229 is a same distance from the edge as the pivot post 225 of the base 20. A pair of securing pieces 241 corresponding to the securing holes 52 of one side of the data storage device 50 extends perpendicularly inward from the first side panel 24.
Referring also to FIG. 2, the pivot member 30 of the mounting bracket 40 includes a second panel 32 and a flange panel 34 extending perpendicularly out from a bottom edge of the second panel 32. A pair of securing pieces 321 corresponding to the securing holes 52 of another side of the data storage device 50 extends perpendicularly inward from the second side panel 32. A pair of anti-EMI plates 323 is formed in the second side panel 32 between the securing pieces 321. A pivot hole 341 corresponding to the pivot post 225 of the base 20 is defined in one end of the flange panel 34. A guiding post 347 corresponding to the arc-shaped slot 229 extends down from a bottom side of the flange panel 34. A rectangular opening 343 corresponding to the clip 2231 is defined in the flange panel near the guiding post 347. A rolled portion 345 is formed at another end of the flange panel 34.
Referring also to FIG. 3-FIG. 5, in assembling, the fixing portions 121 are extended through the corresponding entrance portions of the openings 221 of the base 20, then the base 20 is pushed or pulled to slide in a direction parallel to the bottom panel 12 of the chassis 10 until the fixing portions 121 engage with the securing portions of the openings 221. The bulges 123 of the chassis 10 resist against a bottom side of the bottom panel 22 of the base 20. An interspace is configured between the bottom panel 12 of the chassis 10 and the bottom panel 22 of the base 20 for allowing the free end of the resilient piece 223 to deform downwardly freely. The data storage device 50 is placed on the bottom panel 22 with the securing pieces 241 of the first side panel 24 inserted into the corresponding securing holes 52 of the data storage device 50. The pivot post 225 of the base 20 extends through the pivot hole 341 of the pivot member 30 and the guiding post 347 extends through an outer end of the arc-shaped slot 229 of the base 20. The pivot member 30 rotates clockwise to a locked position where the clip 2231 of the resilient piece 223 of the base 10 engages within the rectangular opening 343 of the pivot member 30 and the rolled portion 345 is firmly caught by the catch 227. The guiding post 347 slides to an inner end of the arc-shaped slot 229 of the base. Thus the pivot member 30 is attached to the side opposite to the first side panel 24 of the base 20. At the same time, the securing pieces 321 are inserted into the corresponding securing holes 52 of the data storage device 50 for securing the data storage device 50 between the first side panel 24 and the second side panel 32.
In removing the data storage device 50 from the mounting bracket 40, the clip 2231 of the resilient piece 223 is pressed down into the interspace between the base 20 and the chassis 10, the pivot member 30 rotates anticlockwise to an unlocked position where the clip 2231 of the base disengages from the opening 343 of the pivot panel 30 and the securing pieces 341 disengage from the securing holes 52 of the data storage device 50, then the data storage device 50 is moved out from the mounting bracket 10.
It is to be understood, however, that even though numerous characteristics and advantages have been set forth in the foregoing description of preferred embodiments, together with details of the structures and functions of the preferred embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
