## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a drive bracket, and particularly to a drive bracket having a locking device which readily secures data storage devices in the drive bracket in any desired positions and allows convenient removal of the data storage devices therefrom.
2. Description of the Related Art
Generally speaking, when a computer is assembled, a drive bracket is mounted in a computer enclosure, and then data storage devices are fixed to the drive bracket. The data storage devices comprise various combinations of hard disk drives (HDDs), floppy disk drives (FDDs), and compact disk-read only memory (CD-ROM) drives.
A conventional data storage device is generally attached to a drive bracket by bolts or rails. Examples are disclosed in Taiwan Patent Application Nos. 82202124, 81207129 and 82207667. Fixing a data storage device to a drive bracket with bolts is unduly laborious and time-consuming. Furthermore, the computer enclosure needs extra operating space for carrying out the fixing operation. Fixing a data storage device in a drive bracket using rails is more convenient than using the above-described bolts. However, certain bolts are still needed to fix the rails to the drive bracket. Additionally, mounting systems using rails require a clearance between the data storage device and the drive bracket. This may cause electromagnetic interference (EMI) problems, and may lead to accumulation of static charges on the computer enclosure. Furthermore, the rails are generally made of plastic. This not only restricts grounding connection options between the data storage device and the drive bracket, but also tends to lead to extra maintenance because of the plastic rails easily wearing out and needing replacement.
Thus an improved drive bracket which overcomes the above-mentioned problems is desired.
SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to provide a drive bracket which readily and conveniently secure data storage devices in any desired positions therein and which allows ready detachment therefrom.
To achieve the above-mentioned object, a drive bracket of a preferred embodiment of the present invention comprises a first latch member and a second latch member to secure a number of data storage devices therein. The first latch member is movably attached to a side panel of bracket via a spring. The second latch member comprises a pair of stops. The stop comprises a pair of slopes and a pair of vertical locating boards. The second latch member is adjustably attached to the first locking member. The data storage device with studs installed in one sidewall thereof is slideably installed in the bracket. The studs switchably ride over the corresponding slopes and are blocked by the vertical boards of the second latch member to secure the data storage devices in the bracket in different positions.
Other objects, advantages and novel features of the present invention will be drawn from the following detailed description of a preferred embodiment of the present invention with attached drawings, in which:

Referring to FIG. 2, an ear 34 extends horizontally outwardly from a top edge of the side panel 33 of the bracket 30. A first connecting hole 341 is defined in the ear 34. A plurality of holding portions 35 arranged in two lines is stamped outwardly from the side panel 33. Referring to FIG. 3, each of the holding portions 35 comprises a domed coping 351 at a top end thereof, and a holding bar 352 extending outwardly from a free vertical edge thereof. Referring also to FIG. 4, a plurality of resilient tabs 36 is formed in the side panel 33 via stamping between the rearmost line of the holding portions 35. A plurality of sliding slots 37 is defined horizontally in the side panel 33.
Referring also to FIGS. 5 and 6, the first latch member 40 comprises a generally rectangular first main body 41. An upright block 42 extends from a top wall of the first main body 41. A second connecting hole 421 is defined in the block 42. The first main body 41 defines a recess 45 in an upper middle portion thereof, and forms a pair of opposite inner walls 451 at both vertical sides of the recess 45. Two pairs of arcuate dents 452 are defined in the inner walls 451, one pair above another pair. A plurality of supporting blocks 43 and catches 44 are separately formed from sidewalls 47 of the first main body 41. The catches 44 are arranged for engaging with the holding portions 35 of the bracket 30.
The second latch member 50 comprises a second main body 51 configured to be fittingly received in the recess 45 of the first latch member 40. An operating beam 55 extends from a lower portion of the second main body 51. A pair of opposite inverted resilient arms 54 is formed in the middle of the main body 51 at opposite sides thereof. Each resilient arm 54 comprises a semi-cylindric protrusion 541 in an outer portion thereof corresponding to the dents 452 of the first latch member 40, and a handle 542 extending from an inner portion thereof. A plurality of resilient hooks 53 is outwardly formed from opposite side portions of the second main body 51. A pair of stops 56 is formed inwardly from the second main body 51, one above another. Each stop 56 comprises a generally U-shaped frame 561 defining a locating space 562 therein. A first slope 563 and a second slope 564 are respectively formed from top edges of the frame 561, with the second slope 564 higher than the first slope 563. A second locating board 565 depends from the second slope 564.
Referring also to FIG. 7, in assembling the second latch member 50 to the first latch member 40, the second latch member 50 is received in the recess 45 of the first latch member 40 with the semi-cylindric protrusions 541 resiliently held in the dents 452. The resilient hooks 53 of the second latch member 50 engage with corresponding inner walls 451 of the recess 45.
Referring also to FIG. 8, in assembly, the combined second latch member 50 and the first latch member 40 is then attached to the side panel 33 of bracket 30. The catches 44 of the first latch member 40 are engagingly held in the corresponding holding portions 35 of the bracket 30 and blocked by the domed copings 351 for preventing a vertical movement of the first latch member 40 relative to the bracket 30. The holding bars 352 of the holding portions 35 engagingly abut against the sidewalls 47 of the first latch member 40 for preventing a horizontal movement of the first latch member 40 relative to the bracket 30. The supporting blocks 43 of the first latch member 40 abut against an outer surface of the side panel 33 of the bracket 30, and the resilient tabs 36 abut against an inner side of the first latch member 40. Two ends of the spring 60 engage in the second connecting hole 421 of the first latch member 40 and the first connecting hole 341 of the bracket 30. The first latch member 40 is thus movably attached to the side panel 33 of the drive bracket 30. Then the bracket 30 is attached to the cage 20 by conventional means such as screws.
The data storage devices 10 are slid into the drive bracket 30 in a front-to-rear direction. In this embodiment, only two upper data storage devices are adjustable between a first locking position and a second locking position. FIGS. 8 and 9 show the data storage devices 10 in the first locking position. In this first position, the semi-cylindric protrusions 541 of the second latch member 50 are located in a lower pair of the dents 452 of the first latch member 40. The data storage devices 10 are supported by the supporting flanges 221. The studs 15 attached to the data storage devices 10 are slid in the slots 37 of the bracket 30. When the studs 15 of the upper data storage devices slide and exert a downward force onto the second slope 561 of the stops 56, the spring 60 is lengthen in a result of the combined first and second latch members 40, 50 moved downwardly along the holding portions 35 of the bracket 30. When the studs 15 ride over topmost edges of the second slope 561, the spring 60 rebounds, and the studs 15 are located between the second locating boards 565 and rear ends of the corresponding slots 37 of the bracket 30. The two upper data storage devices 10 are thus secured in the cage 20 in the first locking position.
Referring also to FIGS. 10 and 11, the two upper data storage devices 10 are in a second locking position. In this second position, the handles 542 of the second latch member 50 are squeezed toward each other and then pushed upwardly, thus the semi-cylindric protrusions 541 are withdrawn from the corresponding dents 452 and are moved to locate in an upper pair of the dents 452 of the first latch member 40. When the studs 15 slide into the slots 37, and exert a downward force onto the first slope 563 of the stop 56, the spring 60 is lengthen in a result of the combined first and second latch member 40, 50 moved downwardly along the holding portions 35 of the bracket 30. The studs 15 ride over topmost edges of the first slopes 563 and fall into the locating spaces 562 of the stops 56, the spring 60 rebounds. The data storage devices 10 are thus secured in the drive bracket 30 in the second locking position.
In this preferred embodiment of the present invention, there are another two stops 46 inwardly formed from the first main body 41 below the recess 45, with one above another. Each stop 46 is generally a triangle, and comprises a slanting board 461 and a vertical locating board 462. The studs 15 of the two lower data storage devices 10 ride over the slanting boards 461, and are blocked by the vertical locating board 462, thereby the lower data storage devices 10 are secured in the drive bracket 30.
In disassembly, the operating beam 55 of the second latch member 50 is depressed so that the first latch member 40 is accordingly moved downwardly, and the spring 60 is lengthen. Then the studs 15 are released from the locating space 562 defined in the frame 561 in the second locking position, or a locating space defined between the locating board 565 and a rear end of the corresponding slots 30 in the first locking position. The data storage devices 10 are thereby freely drawn out from the bracket 30.
According to the number of the data storage devices 10 desired, the number of the stops 47, the slopes 563, 564, and the dents 452 can all be configured accordingly.
