## Background
BACKGROUND
1. Field of the Invention
The present invention relates to fixing apparatuses, and particularly to a fixing apparatus for hard disk drives (HDD).
2. Description of Related Art
The conventional approach now being adopted to mount an HDD in a computer chassis generally involves placing the HDD in a holding area of a drive bracket; screwing a plurality of screws through side walls of the drive bracket into two sides of the HDD to fasten the HDD on the drive bracket; and mounting the HDD and the bracket in a computer chassis or a mobile HDD rack. For proper balanced installation of the HDD, multiple screws should be fastened at the same time, making installing and removing operations of the HDD tedious.
What is desired, therefore, is a fixing apparatus which allows convenient installation and removal of an HDD.
SUMMARY
An exemplary fixing apparatus is for mounting an HDD having a plurality of holes in sidewalls thereof. The fixing apparatus includes a first fixing plate, a bracket, and a transverse bar. The bracket includes a second fixing plate, and a bezel assembly attached to a first end of the second fixing plate. Each of the first fixing plate and the second fixing plate includes a plurality of fixing members formed at inside walls thereof to engage in the holes of the HDD. The first fixing plate is pivotally attached to a free end of the bezel assembly. One end of the transverse bar is pivotally attached to a second end of the second fixing plate opposite to the first end and the other end of the transverse bar detachably engages with the first fixing plate.
Other advantages and novel features will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings, in which:

DETAILED DESCRIPTION OF THE EMBODIMENT
Referring to FIGS. 1 and 2, a fixing apparatus in accordance with an embodiment of the present invention is for fixing a hard disk drive (HDD) 10 and includes a first fixing plate 20, a bracket 30, a transverse bar 40, and two shafts 62, 64.
The HDD 10 includes a pair of holes 12 defined in each of two opposite sidewalls thereof.
The first fixing plate 20 includes a pivoting portion 22 extending slantingly and inward from one end thereof, and a locking portion 24 formed at an inside of the other end thereof. The pivoting portion 22 includes a pivoting hole 222 defined in a free end thereof, and a semi-cylindrical protrusion 224 formed at the outside surface of the free end. The locking portion 24 includes a first wall 242 perpendicular to the first fixing plate 20, and a second wall 243 parallel to the first fixing plate 20 and perpendicularly connecting to the first wall 242. The locking portion 24 and the first fixing plate 20 cooperatively define a receiving space 25. The second wall 243 includes a slot 244 defined in a middle portion thereof, and a cutout 246 defined in an upper portion thereof. A plurality of fixing members 50 is formed at the inside of the first fixing plate 20.
The bracket 30 includes a second fixing plate 32, and a bezel assembly 34 perpendicularly formed at one end of the second fixing plate 32. The second fixing plate 32 includes a pivoting portion 36 formed at an inside of the other end of the second fixing plate 32. The pivoting portion 36 and the second fixing plate 32 cooperatively define a receiving space 37. The pivoting portion 36 includes a pair of spaced walls 362 each perpendicular to the second fixing plate 32. A pair of pivoting holes 364 is defined in the walls 362, respectively. The bezel assembly 34 includes a vertical board 342, and a pair of spaced horizontal boards 344 perpendicular to the vertical board 342. A pair of pivoting holes 346 is defined in outside end portions of the horizontal boards 344, respectively. A resilient tab 343 extends from an inside surface of the vertical board 342. A plurality of fixing members 50 is formed at the inside of the second fixing plate 32.
The transverse bar 40 includes a first depending portion 42 depending from one end thereof, and a second depending portion 44 depending from the other end thereof. The first depending portion 42 includes a pivoting hole 422 defined in an enlarged end portion thereof. The second depending portion 44 includes a wedged block 442 formed at an inside surface thereof, and a handle 444 slantingly extending from a distal end thereof.
Each of the fixing members 50 includes a cap 52, and a pin 54 with one end embedded in the cap 54. The pin 54 is made of metal materials. The cap 52 is made of shock absorbing materials, such as rubber.
Referring to FIG. 3, in assembly, the first fixing plate 20 is pivotably attached to the bezel assembly 34 of the bracket 30. The pivoting portion 22 of the first fixing plate 20 is sandwiched between the horizontal boards 344 of the bezel assembly 34, with the shaft 62 extending through the pivoting holes 346 of the bracket 30 and the pivoting holes 222 of the first fixing plate 20. The semi-cylindrical protrusion 224 engagably abuts the resilient tab 343 of the bracket 30. The transverse bar 40 is attached to the second fixing plate 32 of the bracket 30, with the first depending portion 42 of the transverse bar 40 received in the receiving space 37 and the shaft 64 extending through the pivot holes 364 of the bezel assembly 34 and the pivoting holes 422 of the transverse bar 40.
In use, the first fixing plate 20 is pivoted about the shaft 62 and away from the second fixing plate 32 of the bracket 30 to allow the HDD 10 to be placed in the bracket 30, with the pins 52 of the fixing members 50 of the second fixing plate 32 of the bracket 30 extending into the holes 12 of one sidewall of the HDD 10. Then, the first fixing plate 20 is pivoted toward the HDD 10 so that the pins 52 of the fixing members 50 of the first fixing plate 20 extend into the holes 12 of the other sidewall of the HDD 10. The transverse bar 40 is pivoted downward about the shaft 64 so that the second depending portion 44 thereof is received in the receiving space 25 of the first fixing plate 20 and the wedged block 442 thereof passes through the cutout 246 and engages in the slot 244 of the second wall 243 of the first fixing plate 20.
To release the HDD 10, the handle 444 of the transverse bar 40 is drawn to disengage the wedged block 442 of the transverse bar 40 from the slot 244 of the first fixing plate 20. Then, the first fixing plate 20 is pivoted away from the HDD 10 to release the pins 52 thereof from the corresponding holes 12 of the HDD 10. The HDD 10 is easily taken away from the bracket 30.
It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the examples hereinbefore described merely being preferred or exemplary embodiments.
