BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a mounting apparatus, and more particularly to a mounting apparatus that secures a plurality of data storage devices conveniently.

2. Background of the Invention

With the rapid development of computer technology, properties of computer make a dramatic improvement. However, a computer is still expensive for a common consumer. Accordingly, expansion capacity and convenient installation are two vital factors to be considered when designing computer. Various data storage devices are installed in a computer enclosure for communication and dealing with data. Such a device may be, for instance, a floppy disk drive, a CD-ROM/DVD-ROM drive, a CD-RW/DVD-RW drive or other similar device. Nowadays, a computer enclosure is tightly packed in order to keep the size of the system small to fit on or under a desk. A conventional data storage device is directly attached to a computer enclosure with screws. However, the screws are usually very small, therefore making it difficult for a computer user to hold the screws in position while screwing them in with a screwdriver. The screws are inserted into holes that are on the data storage device assembly and on the chassis to which the data storage device assembly is being attached. The holes are difficult to align because they are also typically very small. Also, if the tolerances are incorrect due to manufacturing defects, the holes may not line up exactly, making it difficult to insert the screws. Obviously, using screws to attach the data storage device to a computer enclosure may be arduous due to requiring insertion of the screws. Both insertion and removal of the screws are time consuming and cumbersome owing to the work space restrictions and difficult accessibility.

In addition, during the course of the operation of the data storage device, it may cause the data storage device to vibrate, therefore to make the screws come loose. As a result, one danger of damaging the data storage device comes into being. Understandably, some attempts have been taken to introduce a mounting apparatus for data storage devices without screws.

What is needed, therefore, is a mounting apparatus for data storage devices facilitating assembly and disassembly in a chassis.

The sidewall 23 forms four elastic locking portions 27 same to the locking portions 16 of the sidewall 13. Each elastic locking portion 27 also has a free end with a protrusion 272 formed outwards thereon. A wedge-shaped cutout (not labeled) is also defined in the protrusion 272. A pin (not labeled) is also extended inwards from an inner side of each locking portion 27. A plurality of L-shaped resisting tabs 28 is extended outwards from the sidewall 13 at a side edge thereof. A positioning hole 29 is defined in the sidewall 23 adjacent to the flange 25. Two parallel slideways 222 are formed on the sidewall 22.

Referring to FIG. 3, the sliding board 30 is generally S-shaped. An elliptic opening 32 is defined in the sliding board 30 at a middle portion thereof. An arris 322 is formed on a top edge of the opening 32. A narrow opening 34 is defined in the sliding board 30 above the opening 32. A through hole 342 is defined in the sliding board 30 over the narrow opening 34 for securing one end of the spring 80. A plurality of quadrate openings 36 is defined in the sliding board 30 corresponding to the free ends of the locking portions 16, 27 of the first bracket 10 and second bracket 20. A generally wedge-shaped block 362 is formed at a bottom edge of each quadrate opening 36 for upwardly lifting the protrusion 162 of the locking portion 16 and the protrusion 272 of the locking portion 27. A plurality of elongated first sliding blocks 38 is extended outwards vertically from an upper side edge of the sliding board 30 corresponding to the vaulted resisting tabs 18. A plurality of second sliding blocks 39 is formed on a lower side edge of the sliding board 30 corresponding to the L-shaped resisting tabs 28.

Referring also to FIG. 5, the rotating member 50 includes a rotating handle 52 formed at one end thereof. A securing hole 54 is defined in a middle portion of the rotating handle 52. An oval turntable 56 connected with the rotating handle 52 is formed on the rotating member 50. A pair of grooves 562 corresponding to the arris 322 of the sliding board 30 is defined in the turntable 56 at upper and lower edges thereof. Similarly, a pair of grooves 564 corresponding to the arris 322 of the sliding board 30 is defined in the turntable 56 at a right end and a left end thereof. A screw 70 is extended through the securing hole 54 of the turntable 52 and the positioning hole 29 of the second bracket 20 to secure the rotating member 50 on the second bracket 20.

The data storage devices 90 may be a CD-ROM drives or other devices, such as DVD-ROM drives, floppy disk drives, CD-RW drives, CD/DVD-RW drives and so on. One sidewall of the data storage devices 90 defines a plurality of locking holes 92 therein corresponding to the pins of the locking portions 16, 27. The other sidewalls of the data storage devices 90 are formed to have guiding blocks (not shown) for sliding in the slideways 222. The first bracket 10 further includes a sidewall (not shown) parallel to the sidewall 13. The sidewalls form a plurality of slideways (not shown) similar to the slideways 222 of the second bracket 20.

Referring to FIG. 6, before the data storage devices 90 are mounted to the first bracket 10 and second bracket 20, the sliding portions 112 of the first bracket 10 firstly slide into the wide portions of the corresponding apertures 256 of the second bracket 20. Then, the sliding portions 112 of the bracket 10 slide into the narrow portions of the corresponding apertures 256 of the second bracket 20 and engage in the apertures 256. A screw (not shown) is extended through the securing hole 114 of the first bracket 10 and the mounting hole 258 of the second bracket 20 for securing the second bracket 20 on the first bracket 10. The first sliding blocks 38 and second sliding blocks 39 of sliding board 30 slide upwardly along the vaulted resisting tabs 18 of the first bracket 10 and the L-shaped resisting tabs 28 of the second bracket 20 until the sliding board 30 is slidably fixed to the first bracket 10 and second bracket 20. A screw 70 is extended through the securing hole 54 of the rotating member 50 and the positioning hole 29 of the second bracket 20 to mount the rotating member 50 on the second bracket 20. Simultaneously, the turntable 56 of the rotating member 50 is received into the opening 32 of the sliding board 30 and the rotating member 30 can pivot about the screw 70. One end of the spring 80 is connected with the hook 14 of the first bracket 10 and the other end of the spring 80 is engaged in the through hole 342 of the sliding board 30. The turntable 56 is pressed by the top edge of the opening 32 of the sliding board 30 due to the spring 80.

In assembly of the data storage devices 90, firstly, the rotating handle 52 of the rotating member 50 is pivoted clockwise or anticlockwise. The turntable 56 of the rotating member 50 lifts upwardly (in a first direction) the sliding board 30 until the arris 322 of the sliding board 30 engages in the groove 564 of the turntable 56. The wedge-shaped blocks 362 of the sliding board 30 insert into the cutouts 164 of the protrusions 162 and the cutouts of the protrusion 272. Consequently, the free ends of the locking portions 16, 27 move outwards so that the pins 166 of the locking portions 16 and the pins of the locking portion 27 also move outwards until the pins 166 of the locking portions 16 and the pins of the locking portion 27 locate outside the sidewall 13 and the sidewall 23. Then, the data storage devices 90 are inserted into the first bracket 10 and second bracket 20 along the slideways 222 of the second bracket 20 and the slideways of the first bracket 10 until the pins 166 of the locking portions 16 and the pins of the locking portion 27 are in alignment with the locking holes 92 of the data storage devices 90 respectively. The rotating handle 52 of the rotating member 50 is pivoted anticlockwise or clockwise so that the arris 322 of the sliding board 30 disengages from the groove 564 of the turntable 56. The silding board 30 moves up and down along with rotation of the rotating member 50 until the arris 322 of the sliding board 30 engages in the groove 562 of the turntable 56. Thus, the wedge-shaped blocks 362 of the sliding board 30 disengage with the protrusions 162 of the locking portions 16 and the protrusions 272 of the locking portions 27. Accordingly, the locking portions 16 and the locking portions 27 come back to an original position due to elasticity. Simultaneously, the pins 166 of the locking portions 16 and the pins of the locking portions 27 insert into the corresponding locking holes 92 of the data storage devices 90 for securing the data storage devices 90. Thereby, the data storage devices 90 are securely mounted in the first bracket 10 and the second bracket 20.

In disassembly of the data storage devices 90, the rotating handle 52 of the rotating member 50 is pivoted clockwise or anticlockwise. The turntable 56 of the rotating member 50 lifts upwardly the sliding board 30 until the arris 322 of the sliding board 30 engages in the groove 564 of the turntable 56. The wedge-shaped blocks 362 of the sliding board 30 insert into the cutouts 164 of the protrusions 162 and the cutouts of the protrusion 272. Consequently, the free ends of the locking portions 16, 27 move outwards so that the pins 166 of the locking portions 16 and the pins of the locking portion 27 are drawn from the locking holes 92 of the data storage devices 90. Thus, the data storage devices 90 can be easily taken out from the first bracket 10 and second bracket 20 along the slideways 222 of the second bracket 20 and the slideways of the first bracket 10.
