## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
Relevant subject matter is disclosed in two co-pending U.S. Patent Applications respectively entitled “MOUNTING APPARATUS FOR STORAGE DEVICES” and “MOUNTING APPARATUS FOR STORAGE DEVICE”, which are assigned to the same assignee of this application with application Ser. Nos. 10/951,425, and 11/200,828.
BACKGROUND
1. Field of the Invention
The present invention relates to a mounting apparatus, and more particularly to a mounting apparatus for a storage device.
2. General Background
The manufacture and assembly of electronic apparatuses have become increasingly more competitive. Manufacturers continually strive to improve the design and features of electronic apparatuses yet still offer competitive prices. One such area of improvement is mounting of devices in an electronic apparatus. An electronic apparatus, such as a typical desktop computer, a tower computer, a server, and the like, usually includes storage devices, such as hard disk drives, compact disk read-only memory (CD-ROM) drives, digital video disc (DVD) drives, floppy disk drives, and the like. These devices are typically added to increase the functionality of the electronic apparatus as desired by a user. However, the installation of such devices in the electronic apparatus is always labor-intensive.
For instance, as disclosed in China Patent No. 92232515.4 and China Laid-open Application No. 01130712.9, the installation of a hard disk drive in a computer typically involves use of screws to attach the hard disk drive to a bracket of a computer chassis. Usually, these screws are small enough to make them difficult to be manipulated. It is laborious and time-consuming to manually manipulate the screws. Additionally, because of their small size, the screws are easier to be dropped by an assembler into the computer. Some accidental damage will occur in the computer due to impact of these moving parts, and the like causes.
To address the aforementioned problems, a plurality of mounting apparatuses is invented to reduce the number of needed screws. For example, a pair of detachable rails is attached to opposite sides of a storage device with screws. The storage device slides into and is secured to a drive bracket. However, the screws have to be removed to detach the rails from the storage device before replacing the storage device.
What is desired, therefore, is a mounting apparatus which conveniently and securely holds a storage device in a bracket.
SUMMARY
In one preferred embodiment, a mounting apparatus includes a bracket, a retainer, and a slider. The bracket is for receiving a storage device therein and includes a first sidewall defining two pairs of apertures therein. The slider is slidably attached to the first sidewall and includes two pairs of slideways, and a pair of resilient arms. The retainer is sandwiched between the first sidewall of the bracket and the slider and abutted against by the resilient arms. The retainer includes two pairs of posts sliding along the slideways, and two pairs of pins extending through the apertures to engage the storage device.
Other advantages and novel features will become more apparent from the following detailed description of preferred embodiments when taken in conjunction with the accompanying drawings, in which:

A pair of guiding pieces 362 is punched inwardly and separately from the first and second sidewalls 34, 36, opposite to each other. Two lines of spaced bridges 345 each with a guiding protrusion 346 are punched outwardly from the first sidewall 34 so as to be used as a guide mechanism of the bracket 30. Two lines of spaced guiding tabs 348 are punched outwardly from the first sidewall 34, between the lines of the bridges 345. A locating tab 349 is punched outwardly from the first sidewall 34, between the lines of the guiding tabs 348 so as to be used as another guide mechanism of the bracket 30. A many pairs of apertures 344 in array are defined in the first sidewall 34 besides two ends of the guiding tabs 348, corresponding to the fixing holes 14 of the storage device 10. Many slots 347 in array are defined in a rear portion of the first sidewall 34 beside the apertures. Many pairs of resilient tabs 364 in array extend inwardly from the second sidewall 36 along the horizontal direction. A protrusion 366 extrudes from each of the resilient tabs 364 in alignment with the corresponding aperture 344 of the first sidewall 34.
The retainer 50 includes a rectangle plate 51, and a pair of flanges 55 extended perpendicularly and outwardly from upper and lower edges of the rectangle plate 51 respectively. Many slits 52 in array are defined in the rectangle plate 51, corresponding to the locating tab 349 of the bracket 30. A tip 54 extends perpendicularly at each comer of the rectangle plate 51, corresponding to the apertures 344 of the bracket 30. A pair of posts 56 extends outwardly from end portions of each flange 55. The post 56 can be replaced by another sliding member, such as a block or a protrusion.
The slider 60 is generally box-shaped. The slider 60 includes a vertical wall 62, and a pair of horizontal walls 64 extending inwardly from upper and lower edges of the vertical wall 62 respectively. A pair of resilient arms 623 extends inwardly from two opposite end portions of the vertical wall 62 and the resilient arms 623 symmetrically extend toward each other. Each of the resilient arms has a curved distal end. A handgrip portion 624 is defined in a middle portion of the vertical wall 62 and extends to the horizontal walls 64. A pair of sliding blocks 642 extends from an edge of each of the horizontal walls 64, corresponding to guiding protrusions 346 of the bridges 345 of the bracket 30. A resilient hook 648 extends outwardly from the edge portion of each of the horizontal walls 64 between corresponding guiding blocks 642, engaging with corresponding guiding tabs 348 of the bracket 30. A pair of slideways 644 is formed in each of the horizontal walls 64 besides the handgrip portion 624. A recess 647 is defined in each of the horizontal walls 64 connecting with the corresponding slideway 644. Each of the slideways 644 includes a sloped wall 645. Each of the slopped walls 645 includes a first end 645anear the vertical wall 62, and a second end 645bfar away the vertical wall 62. A locator 66 is resiliently formed in a rear portion of the vertical wall 62. The locator 66 includes a plug 661 extruding inwardly therefrom, and a handle 663 extending outwardly therefrom.
Referring to FIGS. 3 and 5, in assembly of the mounting apparatus, the retainer 50 is engaged to the first sidewall 34 of the bracket 30, with the locating tab 349 engaged in one of the slots 52 and the tips 54 in alignment with corresponding apertures 344. The slider 60 is placed on the first sidewall 34, with the hooks 648 sliding between corresponding guiding tabs 348. The guiding blocks 642 of the slider 60 slide along the guiding protrusions 346 of the bridges 345. The sliding posts 56 of the retainer 50 are received in the corresponding slidaways 644 via the corresponding recesses 647. The plug 661 of the slider 60 engages in corresponding slit 347 of the bracket 30. The curved distal ends of the resilient arms 623 slidably contact and abut against the retainer 50. The resilient arms 623 therefore urge the rectangle plate 51 toward the first sidewall 34 of the bracket 30, with the tips 54 extending through corresponding aperture 344 of the bracket 30.
In use of the mounting apparatus, FIGS. 4 and 5 show the storage device 10 fixed in the bracket 30. Before installing the storage device 10 into the bracket 30, the handle 663 is drawn outwardly to release the plug 661 from the slot 347 of the bracket 30 by a forefinger of an operator. The handgrip portion 624 is engaged by a thumb of the operator to push the slider 60 rearward, with the guiding blocks 642 moving along corresponding guiding protrusions 346 of the bridges 345 correspondingly. The sliding posts 56 of the retainer 50 slide along corresponding sloped wall 645 from the second end 645b to the first end 645a. The resilient arms 623 are restored to move the retainer 50 away from the first sidewall 34 of the bracket 30. The tips 54 of the retainer 50 disengage from corresponding apertures 344 of the first sidewall 34 of the bracket 30. Then the storage device 10 is moved into the bracket 30, with the guiding pieces 362 engaging on the top wall 11 of the storage device 10 and the resilient tabs 364 abutting the sidewalls 12 of the storage device 10. When a rear pair of fixing holes 14 of the storage device 10 approximately reaches one front pair of the apertures 344 of the bracket 30, the slider 60 is pushed frontward. The sliding posts 56 of the retainer 50 slide along corresponding sloped wall 645 from the first end 645a to the second end 645b. The resilient arms 623 are depressed to urge the retainer 50 toward the first sidewall 34. The tips 54 of the retainer 50 are extended through the apertures 344 to abut the sidewall 12 of the storage device 10. When the fixing holes 14 of the storage device 10 are in alignment with corresponding apertures 344 of the bracket 30, the tips 54 are extended into the fixing holes 14. At the same time, the protrusions 366 of the second sidewall 36 of the bracket engage in the fixing holes 14 of an opposite sidewall of the storage devices 10. The plug 661 of the slider 60 engages in the corresponding slot 347 of the bracket 30. The storage device 10 is fixed in the bracket 30.
The storage device 10 is selectively located in different positions in the bracket 30, so that the bracket 30 is able to receive the storage device 10 in a plurality of selective places therein, with the tips 54 of the retainer 50 engaging in different pairs of the apertures 344 of the bracket 30, the locating tab 349 of the bracket 30 engaging in different slits 52 of the retainer 50, the plug 661 of the slider 60 engaging in different slots 347 of the bracket 30, and the fixing holes 14 of the storage device 10 engaging with different protrusions 366 of the bracket 30. In this case, the retainer 50 therefore can be attached to the slider 60 in a selective place corresponding to a selected place of the storage device 10 in the bracket and is movable in a direction perpendicular to the bracket.
To detach the storage device 10, the handle 663 of the slider 60 is drawn outwardly to separate the plug 661 from the slot 347. The slider 60 is moved rearward, the sliding posts 56 of the retainer 50 slide along the corresponding sloped walls 645 from the second end 645b to the first end 645a. The resilient arms 623 are restored to move the retainer 50 away from the first sidewall 34 of the bracket 30. The tips 54 withdraw from the fixing holes 14 of the storage device 10. The storage device 10 is easily detached from the bracket 30.
It is believed that the present embodiment and its 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 example hereinbefore described merely being a preferred or exemplary embodiment.
