DETAILED DESCRIPTION OF THE INVENTION

Referring to FIG. 1, a drive bracket assembly used for securing a data storage device includes a computer enclosure 10, a drive bracket 30 slidably mounted in the computer enclosure 10 for accommodating the data storage device, and a latch member 50 pivotably attached to the drive bracket 30 for securing the drive bracket 30 in the computer enclosure 10.
The computer enclosure 10 includes a bottom wall 11 and a side wall 12 perpendicular thereto. A rectangular carrying board 13 protrudes up from the bottom wall 11 with a plurality of securing slots 130 defined therein. Each securing slot 130 has a wide mounting portion 131 and a narrow securing portion 132. An L-shaped blocking member 133 is formed on a short side of the carrying board 13. A limiting tab 135 is formed on the carrying board 13 and aligned with the blocking member 133. A pair of limiting tabs 137 is formed on the bottom wall 11 of the computer enclosure 10 adjacent to a long side of the carrying board 13, for helping the drive bracket 30 slide on the carrying board 13 smoothly.
The drive bracket 30 includes a bottom wall 31 and a side wall 33 perpendicular to the bottom wall 31. A plurality of securing members 310 is formed on the bottom wall 31 of the drive bracket 30 for engaging with the securing slots 130. Each securing member 310 includes a pair of opposite narrow arms 311 respectively extends down from the bottom wall 31 and a wide securing portion 312 connected between the arms 311. An arcute guiding slot 331 is defined in the side wall 33. The guiding slot 331 compries a wide entrance and a narrow arcute sliding portion. A circular protrusion 332 with a calabash-shaped pivot hole 335 defined therein is formed on the side wall 33. The pivot center of the pivot hole 335 is concentric with the pivot center of the arcute sliding portion. An elastic stop member 336 is formed between the guiding slot 331 and the pivot portion 332. An L-shaped blocking tab 337 extends from a top edge of the side wall 33 over the stop member 336.
Referring also to FIG. 2, the latch member 50 includes a base body which includes a horizontal portion 51 and a slanted portion 53 extending up from an end of the horizontal portion 51. A circular pivot portion 55 is formed at another end of the horizontal portion 51. A circular recess 551 is defined in the pivot portion 55 with a calabash-shaped pivot member 553 protruding from a center thereof. The pivot member 553 has a securing head 556 which is thinner than the other portion of the pivot member 553 such that the securing head 556 is extendable through the pivot hole 335 to rotatably engage with an inner surface of the protrusion 332 of the drive bracket 30 when the pivot member 553 rotates in the pivot hole 335. A rectangular notch 511 is defined in the horizontal portion 51 of the latch member 50 for engaging with the blocking tab 336 of the drive bracket 30. An L-shaped sliding block 531 protrudes from an inner surface of the slanted portion 53 of the latch member 50, for extending through the L-shaped guiding slot 331 and engaging with an inner surface of the side wall 33. An elastic cantilever arm 57 extends up at an incline toward the slanted portion 53 from a top of the pivot portion 551 of the latch member 50. An angle is defined between the elastic cantilever arm 57 and the horizontal portion 51 of the base. A handle 56 extends from a top edge of the slanted portion 53 of the latch member 50. A stop block 59 protrudes laterally from a bottom edge where the horizontal portion 51 and the slanted portion 53 of the latch member 50 join.
Referring also to FIG. 3, for mounting the latch member 50 to the drive bracket 30, the pivot member 553 and the sliding block 531 of the latch member 50 respectively extend through the pivot hole 335 and the guiding slot 331 of the drive bracket 30. The elastic cantilever arm 57 of the latch member 50 is disposed under the blocking tab 337. The handle 56 is pulled up to drive the latch member 50 to rotate up. The latch member 50 slides up with the horizontal portion 51 thereof depressing the elastic stop member 336 until an upper edge of the notch 511 engages with the free end of the elastic stop member 336, thereby preventing the latch member 50 from dropping down. At this point, the latch member 50 is retained by the elastic stop member 336, and the elastic cantilever arm 57 is in an initial state. The sliding block 531 of the pivot member 55 is moved away from the wide entrance of the slot 331 into the narrow sliding portion of the slot 331 and the securing head 556 of the pivot member 55 is moved offset from the slot 335. Thus, the sliding block 531 and the securing head 553 engage with the side wall 33 of the drive bracket 30 in a direction perpendicular to the side wall 53, thereby preventing the sliding block 531 and the securing head 553 of the pivot member 55 disengaging from the guiding slot 331 and the pivot hole 335 of the drive bracket 30 respectively.
Referring also to FIGS. 3-5, in assembly, the securing portions 312 of the securing members 310 on the drive bracket 30 are aligned with the wide mounting portions 131 of the securing slots 130 in the carrying board 13. The stop block 59 of the latch member 50 abuts on the blocking member 133 of the carrying board 13, as shown in FIG. 5. The elastic cantilevel arm 57 of the latch member 50 resists against the blocking tab 337 of the bracket and is distorted by the resistance. The angle between the elastic arm 57 and the horizontal portion 51 of the base becomes smaller. Then, the drive bracket 30 with the latch member 50 mounted thereto is pushed horizontally along the pair of limiting members 137. One of the securing portions 312 of each securing member 310 engages in the corresponding narrow securing portion 132 of the corresponding securing slot 130. The securing portions 312 of the securing members 310 slide below the carrying board 13 and are blocked thereby, for limiting a movement of the drive bracket 30 in a vertical direction away from the carrying board 13. The stop block 59 of the latch member 50 drops down from a top plane of the blocking member 133 and is sandwiched between the blocking member 133 and the side wall 33 of the bracket, as shown in FIG. 3. The elastic cantilever arm 57 of the latch member 50 rebounds back to force the stop block 59 to abut on the carrying board 13. Thus, the movement of the drive bracket 30 in a horizontal direction parallel to the carrying board 13 is limited. The bracket 30 is secured in the computer enclosure 10.
In disassembly, the handle 56 of the latch member 50 is pulled up, the elastic cantilever arm 57 is distorted by the blocking tab 337 of the drive bracket 30. The angle between the elastic cantilever arm 57 and the horizontal portion 51 of the latch member 50 becomes smaller. The base body of the latch member 50 rotates up about the pivot member 553. When the stop block 59 of the latch member 50 raises to a position higher than the top plane of the blocking member 133 of the carrying board 13, the bracket 30 is pulled horizontally out along the pair of limiting tabs 137, and the securing portions 312 of the securing members 310 disengage from the securing slots 130. The side wall 33 of the drive bracket 30 is blocked by the limiting tab 135 on the carrying board 13, for preventing further movement of the drive bracket 30. Thus, the drive bracket 30 is disengaged from the carrying board 13 of the computer enclosure 10.
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.
