## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a mounting apparatus, particularly to a mounting apparatus for securing data storage devices, such as hard disk drives, floppy disk drives, compact disk read-only memory (CD-ROM) drives, etc.
2. Description of Related Art
Usually, a data storage device is simply screwed to a computer enclosure. This conventional mounting means substantially wastes time, and thus adds to the complexity and difficulty of assembling the data storage device to the computer enclosure and later disassembling therefrom.
Another means of mounting a data storage device uses a bracket, a pair of slide members attached to the data storage device, and a pair of levers pivotably secured to the bracket. The bracket defines a pair of through openings therein. The slide members are disposed on the data storage device. Each slide member has a resilient engagement portion, for engaging in the through openings of the bracket respectively. Each of the levers has a projecting portion for urging the corresponding engagement portion of the slide member to resiliently deform. In assembly, the data storage device together with the slide members is inserted into the bracket. When the engagement portions of the slide members are received in the through openings of the bracket, the data storage device is secured in the bracket. At this time, the projecting portions of the levers abut against the engagement portions of the slide members respectively. In removing the data storage device, the levers are pivoted to have the projecting portions resiliently deform the engagement portions of the slide members respectively, thereby disengaging the engagement portions from the corresponding through openings of the bracket. Thus, the data storage device can be removed from the bracket. However, due to the number of elements needed and the complexity of the structure, the mounting apparatus described above is expensive to manufacture.
What is needed, therefore, is a mounting apparatus conveniently securing a storage device to a bracket of a computer enclosure and having a simple structure.
SUMMARY OF THE INVENTION
A mounting apparatus is provided for securing a data storage device. The data storage device has two opposite side walls. Each sidewall forms a pair of posts. The mounting apparatus includes a chassis, a bracket mounted in the chassis for accommodating the data storage device, and a latch member pivotally mounted to the bracket. A plurality of slots is defined in one side wall of the bracket for receiving the posts of the data storage device. The latch member includes a base. An elastic arm and a hook respectively extend from the base. The elastic arm resists against the chassis to urge the hook partially covering one of the mounting slots for preventing a corresponding post received in the mounting slot disengaging therefrom. The latch member is being pressable to depress the elastic arm and remove the hook away from the mounting slot thereby release the corresponding post.

DETAILED DESCRIPTION OF THE INVENTION
Referring to FIG. 1, a mounting apparatus used for securing a data storage device 10 includes a bracket 30 for accommodating the data storage device 10, a latch member 50 pivotably attached to the bracket 30 for securing the data storage device 10 in the bracket 30, and a chassis 70. The data storage device 10 may, for example, be a hard disk drive, a floppy disk drive, a compact disk read-only memory (CD-ROM) drive, etc. The data storage device 10 includes a pair of side walls, and each side wall has a pair of posts 11.
The bracket 30 includes a bottom wall 31, and a pair of opposite side walls 33, 35 perpendicular to the bottom wall 31. Each side wall 33, 35 defines a pair of mounting slots 331, 351 for respectively accommodating the posts 11 of the data storage device 10. The mounting slots 331, 351 are L-shaped, and each mounting slot has a horizontal end and a vertical end extending to a top edge of the corresponding side wall. The side wall 35 defines an arched guiding slot 356 adjacent to one of the mounting slots 351. The guiding slot 356 includes a wide portion 353 connected to a narrow portion 355. An elastic stop member 357 protrudes from an outside of the side wall 35 adjacent to the guiding slot 356. A calabash-shaped pivotal hole 359 is defined between the pair of mounting slots 351.
Referring also to FIG. 2, the latch member 50 includes a substantially triangular base 51. A sliding block 52 corresponding to the guiding slot 356 protrudes inward from the base 51. The sliding block 52 includes a narrow sliding portion 521 extending from the base 51 for sliding in the narrow portion 355 of the guiding slot 356, and a wide securing portion 523 laterally extending from a free end of the narrow sliding portion 521 of the sliding block 52. The securing portion 523 of the sliding block 52 is a little smaller than the wide portion 353 of the guiding slot 356 in the bracket 30 such that the securing portion 523 is extendable through the wide portion 353 of the guiding slot 356. When the narrow sliding portion 521 slides in the narrow portion 355 of the guiding slot 356, the securing portion 523 engages to the side wall 35 of the bracket 30. A recess 53 corresponding to the elastic stop member 357 of the bracket 30 is defined in the base 51 adjacent to the sliding block 52. A calabash-shaped pivot member 55 corresponding to the pivot hole 359 of the bracket 30 protrudes from a first corner of the triangular base 51. The pivot member 55 includes a securing head 551 which is thinner than the other portion of the pivot member 55 such that the securing head 551 is extendable through the pivot hole 359 to slidably engage with the inner surface of the side wall 35 of the bracket 30 when the pivot member 55 rotates in the pivot hole 359. A hook 56 extends from a second corner of the triangular base 51. A receiving space 561 is defined between the hook 56 and the base 51. An arched elastic arm 57 extends from the first corner of the base 51 adjacent to the pivot member 55 toward the hook 56. A handle 59 protrudes up from a third corner of the base 51.
The chassis 70 includes a bottom wall 71. A limiting tab 73 extends up from the bottom wall 71 corresponding to the elastic arm 57 of the latch member 50.
Referring also to FIG. 3, in assembly, the bracket 30 is mounted in the chassis 70 in a manner known by persons in the art. The elastic arm 57 of the latch member 50 is disposed on the bottom wall 71 of the chassis and sandwiched between the limiting tab 73 and the side wall 35 of the bracket 30. The pivot member 55 and the sliding block 52 of the latch member 50 are respectively aligned with the pivot hole 359 and the guiding slot 356 and engaged therein. The handle 59 is pressed to drive the latch member 50 to rotate down and depress the elastic arm 57. The latch member 50 slides down with the base 51 thereof depressing the elastic stop member 357 until a bottom edge of the recess 53 engages with the bottom end of the elastic stop member 357, thereby preventing the latch member 50 from rotating back. At this point, the latch member 50 is retained by the elastic stop member 357, and the elastic arm 57 is in an initial state. The securing portion 523 of the sliding block 52 and the securing head 551 of the pivot member 55 are respectively rotated down and engage with the side wall 35 of the bracket 30, thereby preventing the slide block 52 and the pivot member 55 disengaging from the guiding slot 356 and the pivot hole 359 of the bracket 30 respectively. The horizontal end of one mounting slot 351 in the side wall 35 is partially blocked by the hook 56 of the latch member 50.
Referring also to FIGS. 4 and 5, in use, the handle 59 is pressed to drive the latch member 50 to rotate down about the pivot member 55. The elastic arm 57 is further pressed, and the hook 56 of the latch member 50 moves down to entirely expose the horizontal end of the mounting slot 351. The latch member 50 is then in a second state. The posts 11 of the data storage device 10 are respectively aligned with the vertical ends of the mounting slots 351 and slide therein. Then, the data storage device 10 is pushed along the horizontal end of the mounting slot 351 until the posts 11 abut inner portions of the horizontal end of the mounting slot 351. The handle 59 of the latch member 50 is then released and the elastic arm 57 rebounds to the initial state. The hook 56 of the latch member 50 moves back to partially block the horizontal end of the mounting slot 351. One of the posts 11 is accommodated in the receiving space 561 and retained in the mounting slot 351 of the bracket 30 by the hook 56. Thus, the data storage device 10 is secured to the bracket 30.
In disassembly, the handle 59 of the latch member 50 is pressed down to drive the hook 56 of the latch member 50 to move under a bottom edge of the horizontal end of the mounting slot 351. Then, the data storage device 10 is pulled out from the mounting slot 351 and removed from the bracket 30.
It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, 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.
