The pivot posts 4112, 4223 of the first and second handles 41, 42 respectively slide into the first and second sliding slots 2113, 2114 of the tray 20 via the entries 21132, 21142, so that the first and second handles 41, 42 are pivotably and slidably secured in the holding slot 210 of the tray 20. The first and second handles 41, 42 are rotated, until the protrusion 4142 of the first handle 42 is received in the receiving opening 422 of the second handle 42. The pivot holes 4143 of the first handle 41 are aligned with the pivot holes 4221 of the second handle 42. The fastener 43 is then engaged in the pivot holes 4221, 4143, so that the first handle 41 is pivotably connected to the second handle 42, thereby preventing the pivot posts 4112, 4223 disengaging from the sliding slots 2113, 2114 of the tray 20 via the entries 21132, 21142.
The latch member 40 is capable of moving from an unlocked position to a locked position. When the latch member 40 is positioned in the unlocked position, the first and second handles 41, 42 are rotated out from the holding slot 210. The blocking flange 4144 of the first handle 41 abuts against an edge of the receiving opening 422 of the second handle 42, to prevent the first handle 41 from further rotating relative to the second handle 42. The pivot posts 4112 of the first handle 41 are slid to a position adjacent the entries 21132 of the sliding slots 2113 from a position away from the entries 21132. The finger piece 35 of the shielding member 30 abuts against the second handle 42. The positioning tab 4224 is positioned in the holding slot 210. When the latch member 40 is positioned in the locked position, the first and second handles 41, 42 are rotated in the holding slot 210. The pivot posts 4223 are slid from the position adjacent the entries 21132 to the position away from the entries 21132. The finger piece 35 of the shielding member 30 is pressed by the second handle 42 and resiliently deformed. The blocking tab 4222 engages with the hook 24 to block the second handle 42 from rotating out of the holding slot 210.
The disk drive 50 is placed on the base wall 223 and the arc-shaped flange 222 of the support portion 22 of the tray 20, and sandwiched between the lateral walls 221. The top wall 52 abuts on the base wall 223 and the arc-shaped flange 222. The fasteners 512 are secured in the securing holes 2211 of the lateral walls 221, so that the disk drive 50 is fixed on the tray 20.
In assembling the disk drive 50 in the bracket 10, the latch member 40 is positioned in the unlocked position, and then the tray 20 and the disk drive 50 are together inserted into the bracket 10 and supported on the support flange 131, until the positioning tab 4224 is positioned corresponding to the positioning opening of the side wall 13 of the bracket 10. The latch member 40 is moved from the unlocked position to the locked position. The positioning tab 4224 is rotated out of the holding slot 210 and engaged in the positioning opening, so as to prevent the tray 20 and the disk drive 50 sliding out from the bracket 10. Thus, the tray 20 and the disk rive 50 are secured in the bracket.
In disassembling the disk drive 50 from the bracket 10, the hook 24 is pressed down to resiliently deform and to disengage from the blocking tab 4222 of the second handle 42. The finger piece 35 of the shielding member 30 thereby rebounds to rotate the second handle 42 out of the holding slot 210 until the latch member 40 is moved from the locked position t to the unlocked position. The positioning tab 4224 is disengaged from the positioning opening 132 of the bracket 10 and rotated in the holding slot 210, so that the tray 20 and the disk drive 50 can be drawn out from the bracket 10.
