## Background
BACKGROUND
1. Technical Field
The present invention relates to mounting apparatuses, and more particularly to a mounting apparatus for a disk drive of a computer or a server.
2. General Background
A disk drive, such as an HDD (hard disk drive), a CD-ROM (compact disc read-only memory) drive, is usually provided in a computer. A bracket is formed on a front plate of a computer enclosure. Usually, the HDD and the CD-ROM are separately installed in the bracket after a motherboard is installed in the computer enclosure, and large space is needed in the computer enclosure. However, in some thin computer enclosures, the space is so limited that the HDD cannot be installed in the bracket after a motherboard is installed.
What is needed, therefore, is a computer enclosure having a bracket allowing easy installation of an HDD therein either in a conventional computer or in a thin computer.
SUMMARY
A computer enclosure includes a chassis and a bracket secured in the chassis. The bracket includes a bottom wall and two parallel first side walls bent from opposite edges of the bottom wall in a first direction for securing a first disk drive therebetween. The bottom wall defines an opening for a second disk drive inserting therethrough. Two parallel second side walls are bent from opposite edges of the opening in a second direction for securing a second disk drive therebetween. The second direction opposes to the first direction.

An L-shaped first bent piece 25 and an L-shaped second bent piece 27 extend outward from a top edge of the first side wall 204. Each of the first and second bent pieces 25, 27 includes a horizontal portion perpendicular to the first side wall 204, and a vertical portion parallel to the first side wall 204. A post 251, which may be a screw, is fixed on the vertical portion of the first bent piece 25 of the first side wall 204, corresponding to the latch slot 14 of the side plate 11 of the chassis 10. The vertical portion of the second bent piece 27 can be inserted into the locking slot 12 of the side plate 11 and slide in the locking slot 12 along a direction parallel to the top edge of the side plate 11, so that the post 251 of the first bent piece 25 can be slid from the vertical portion to the horizontal portion of the latch slot 14. A rectangular opening 202, and a mounting hole 22 corresponding to the pole 17 of the chassis 10 are defined in the bottom wall 201. Two parallel second side walls 206, 207 are bent down from opposite edges of the opening 202. The second side walls 206, 207 are perpendicular to the first side walls 203, 204. A bottom flange (not labeled) is perpendicularly bent in from the bottom of each of the second side walls 206, 207. The bottom flanges of the second side walls 206, 207 are connected with two connecting pieces 21. Three L-shaped latch slots 23 are respectively defined in each of the second side walls 206, 207. Each latch slot 23 includes a horizontal portion generally parallel to top edges of the second side walls 206, 207, and a vertical portion generally perpendicular to the top edges of the second side walls 206, 207. A pair of up and low mounting pieces 29, each with a pivot hole (not labeled) defined therein, are formed on and perpendicular to the second side wall 207.
Referring to FIGS. 1 and 2, the tray 30 includes a top wall 34, and a pair of parallel side walls 31 perpendicularly bent down from opposite edges of the top wall 34. A plurality of resilient slanted finger pieces 35 is formed down on the top wall 34 by stamping. A generally L-shaped securing slot 33, and a cutout 37 are defined in each of the side walls 31. The securing slot 33 includes a horizontal portion generally parallel to a top edge of the side wall 31, and a vertical portion generally perpendicular to the top edge of the side wall 31. The cutout 37 extends in a direction parallel to the top edge of each side wall 31. A positioning portion 332 is formed on an end of a bottom edge of the horizontal portion of the securing slot 33. A post 32, which may be a screw, is fixed on each of the side walls 31 between the securing slot 33 and the cutout 37.
The locking member 60 is includes an operating portion 61 and a positioning portion 64. A pair of pivot shafts 65 is disposed on opposite sides of the locking member 60 between the operating portion 61 and the positioning portion 64. A resilient finger tab 62 extends aslant from the operating portion 61 for retaining the locking member 60 in an original position. A positioning slot 63 is defined in an outer end of the positioning portion 64.
Referring to FIGS. 1 and 2, a second disk drive 40, such as an HDD, with two posts 41 disposed respectively on opposite side walls is secured on the tray 40 between the side walls 31. The posts 41 are respectively positioned in the cutout 37 and the securing slot 33, and blocked by the positioning portions 332 from sliding in the horizontal portions of the securing slots 33. The finger pieces 35 are compressed by the top surface of the disk drive 40 and resiliently deformed to thereby urge the posts 41 to tightly abut against the corresponding positioning portions 332. When it is desired to detach the disk drive 40 from the tray 30, the disk drive 40 is pushed towards the top wall 34 of the tray 30 to resiliently deform the finger pieces 35. The posts 41 of the disk drive 40 are thereby disengaged from the positioning portions 332 of the securing slots 33, and can be thus slid out of the horizontal portions of the securing slots 33. Thus, the disk drive 40 can be taken away from the tray 30.
Referring to FIG. 3, the locking member 60 is pivotably secured between the mounting pieces 29 of the second side wall 207 with the pivot shafts 65 inserting into the corresponding pivot holes of the mounting pieces 29. The positioning portion 64 of the locking member 60 abuts on an outer surface of the second side wall 207, and the finger tab 62 is in an original state.
Referring to FIG. 3, the disk drive 40 together with the tray 30 is inserted between the first side wall 206, 207 of the bracket 20 through the opening 202 of the bottom wall 201, along a vertical direction perpendicular to the bottom wall 201. The posts 32 of the tray 30 and the posts 41 of the disk drive 40 are respectively slid into the latch slots 23 of the second side walls 206, 207 of the bracket 20. The positioning slot 63 of the locking member 60 receives the post 32 of the tray 30, thereby the positioning portion 64 blocking the post 32 from sliding away from the horizontal portion of the corresponding latch slot 23. When it is desired to remove the disk drive 40, the operating portion 61 of the locking member 60 is pressed to pivot the positioning portion 64 away from the second side wall 207, thereby releasing the post 32 of the tray 30 to allow the post 32 to slide from the horizontal portion to the vertical portion of the corresponding latch slot 23 by pushing the disk drive 40. Thus, the disk drive 40 and the tray 30 can be detached from the bracket 20.
Referring also to FIG. 4, the bracket 20 is fixed on the chassis 10. The post 251 of the first bent piece 25 of the bracket 20 is inserted into the horizontal portion from the vertical portion of the latch slot 14. The vertical portion of the second bent piece 27 is inserted into the locking slot 12. The bottom wall 201 of the bracket 20 is retained on the support piece 151 of the front plate 15 of the chassis 10. The cutouts 154 align with the vertical portions of the three corresponding latch slots 23 of the first side wall 206. The mounting hole 22 of the bracket 20 aligns with the mounting hole of the pole 17 of the bottom plate 18 of the chassis 10. A mounting member 50, such as a screw, is inserted into the mounting hole of the pole 17 via the mounting hole 22, thereby preventing the post 251 of the bracket 20 sliding out from the latch slot 14. The bracket 20 is thus stably secured in the chassis 10.
It is to be understood, however, that even though numerous characteristics and advantages have been set forth in the foregoing description of preferred embodiments, together with details of the structures and functions of the preferred embodiments, 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.
