Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to mounting apparatus, and particularly to a mounting apparatus for steadily and securely mounting a data storage device therein.

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 drive bracket is generally attached to a computer enclosure by bolts or rails. Fixing the drive bracket to the computer enclosure with bolts is unduly laborious and time-consuming: Furthermore, the computer enclosure needs extra operating space for carrying out the fixing operation. Since components of a computer are compactly arranged in a computer enclosure, the assembly and disassembly thereof is complicated and low efficient. Moreover, the components may be destroyed by inadvertent operation. Fixing a drive bracket in a computer base using rails is more convenient than using the above-described bolts. However, the rails are generally made of plastic. This leads to extra maintenance because of the plastic rails easily wearing out and resultantly needing replacement.

Another computer enclosure with drive bracket assembly is disclosed in Taiwan patent application No. 091212339. The drive bracket assembly comprises a drive bracket, an assembly panel, and a positioning device. A clip plate, which can move in lateral directions, is formed on a side plate of the drive bracket. The clip plate has elastic restoring force. A bevel guiding edge and a clip slot are formed at a front edge of the clip plate. A clip member is formed on the assembly panel corresponding to the clip slot. The assembly panel can be a surface of a computer base or an inner surface of a computer enclosure. The positioning device comprises at least a guiding groove and a corresponding positioning member. The guiding groove and the positioning member are formed on a proper position between the drive bracket and the assembly panel. The positioning member is engaged in the clip slot of the clip plate to secure the bracket on the assembly panel. The clip plate is moved away to make the positioning member disengage from the clip slot, thus the bracket is disassembled from the assembly panel. However, the assembly and disassembly of the drive bracket still need to be operated in inner space of a computer enclosure.

Thus an improved computer enclosure which overcomes the above-mentioned problems is desired.

BRIEF SUMMARY OF THE INVENTION

The drive bracket 10 is an integrative pane with ladder bend. The drive bracket 10 includes a first side wall 12, a second side wall 14 and a third side wall 16 which are all parallel to each other. There is a joint plate 26 between the first side wall 12 and the second side wall 14, on which defines a confining hole 18 and a downwardly baffle 24. The confining hole 18 is defined due to downwardly depressing of the joint plate 26 with each side is an inverse trapezium. A sliding slice 22 is stamped outwardly from the joint of the second side wall 14 and the joint plate 26.

The locking device 30 includes a sliding portion 32, an elastic patch 46, a spring 54 and a screw 56. The sliding portion 32 is approximately a rectangle lathing. An L-shaped locking patch 44 is bent from a bottom of the sliding portion 32 outwardly and downwardly for connecting with an end of the spring 54. An L-shaped fixing patch 38 extends from an upper portion of a long side of the sliding portion 32. A first screw bole 39 is defined in the fixing patch 38. An operating part 42 vertically extends from the long side of the sliding portion 32 in a direction contrary with that of the fixing patch 38 and located below the fixing patch 38. Two long sides of the sliding portion 32 are overlapping bent to form bending parts 36. The elastic patch 46 is a metal sheet and includes a pressing part 48 and a fixing part 51. The fixing part 51 defines a second screw hole 52.

The computer chassis 70 includes a first container wall 72, a support wall 74, a second container wall 76 and a bottom plate 77. The support wall 74 is a plastic block, which is vertical to the bottom plate 77 and parallel to the first container wall 72 and the second container wall 76. A front plate 73 is formed at the joint of the first container wall 72 and the support wall 74. A plurality of L-shaped catches 75 is formed inwardly from the front plate 73. The catches 75 fix the locking device 30 to the front plate 73 of the chassis 70. An opening 78 is defined in the front plate 73 corresponding to a ladder-shaped cross-section of the drive bracket 10. A vertical slot 82 is defined in the middle of the front plate 73, which is used to hold the operating part 42 of the locking device 30. A lower part of the front plate 73 inwardly forms a hem 79. A fixing tab 84 protrudes upwardly from the hem 79 below the catches 75. The fixing tab 84 can be also directly stamped from the bottom plate 77. A sliding slot 86 is defined in the support wall 74 according to the sliding slice 22 of the second slide wall 14 of the drive bracket 10.

The bending parts 36 of the sliding portion 32 are installed in the catches 75 of the front plate 73. The operating part 42 of the sliding portion 32 extends through the slot 82 of the front plate 73. Two ends of the spring 54 are respectively fixed with the locking patch 44 of the sliding portion 32 and the fixing patch tab 84 of the chassis 70. The drive bracket 10 is moved in the chassis 70 inwardly through the opening 78. The sliding slice 22 slides along the sliding slot 86 of the support wall 74. When the confining patch 34 slides to the confining hole 18 along a slope of the confining hole 18, the spring 54 is elastically deformed, then the confining patch 34 falls in the confining hole 18 via the restoring force of the spring 54. Consequently, the drive bracket 10 is fixed with the chassis 70. Synchronously, the pressing part 48 of the elastic patch 46 moves slightly with the locking device 30 and stays above the baffle 24 of the drive bracket 10 when the baffle 24 moves near the pressing part 48 with the drive bracket 10 and is slightly elastically deformed due to engagement of the baffle 24 and the pressing part 48. Upper edges of the first side wall 12 and the third side wall 16 of the drive bracket 10 are slidably support by connect to the first container wall 72 and the second container wall 76 of the chassis 70, which strengthen the joint of the drive bracket 10 and the chassis 70.

In disassembly, press the operating part 42 of the sliding portion 32 downwardly, the spring 54 is compressed by the sliding portion 32. The confining patch 34 is released from the confining hole 18, synchronously, with the force by the elastic patch 46 pressing the baffle 24, the drive bracket 10 is pushed to move outwardly along the sliding slot 86, so that users can easily take out the drive bracket 10.

The elastic patch 46 may be other elastic component, and the means for jointing the elastic patch 46 and the fixing patch 38 doesn't limit to the screw, other fixing means such as riveting or soldering is acceptable. The sliding portion 32 may be slidably attached to the front plate 73 by other means.

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 type, arrangement of components within the principles of the invention to the full extent indicated by general meaning of the terms in which the appended claims are expressed.
