## Title
Retaining apparatus for locking disk drive

## Abstract

A retaining apparatus for locking a disk drive within a bracket is disclosed. The retaining apparatus includes a latch member and a securing member. The latch member includes a securing portion and a locking portion capable of locking the disk drive in the bracket. A resisting piece is formed on the securing member to resist against the latch member to move towards the bracket to block the disk drive from moving out of the bracket.

## Background
BACKGROUND
1. Technical Field
The present disclosure relates to a retaining apparatus and, particularly, to a retaining apparatus for locking a disk drive in a bracket.
2. Description of Related Art
Disk drives and other peripheral electronic components are frequently mounted on a carrier that can be slidably inserted into a chassis. The carrier usually includes a pair of carrier rails positioned on either side thereof to match the chassis rails. A latching mechanism is usually included to latch the disk drive in the carrier. A drawback of current carriers of removable disk drives is their relatively large size. Additionally, the number of parts required to assemble the carriers increases the cost of the disk drive bracket.

DETAILED DESCRIPTION
Referring to FIG. 1, a retaining apparatus includes a bracket 10 for accommodating a plurality of disk drives 20, a latch member 30, an elastic component 40, and a securing member 50. The latch member 30 is capable of locking the disk drives 20. A plurality of mounting holes 21 is defined in a side of each disk drive 20.
The bracket 10 includes two side panels 11, 12. A plurality of parallel guide flanges 14 is formed on the two side panels 11, 12. Opposite ends of each guide flange 14 are bent to form a resilient pressing portion 141. A plurality of holes 15 is defined in the side panel 11 corresponding to the mounting holes 21. A plurality of bent flanges 16 extend from the side panel 11 to form a slideway. A positioning piece 17 projects from a bottom portion of the bracket 10. A plurality of locking portions 31 protrude from a middle portion of the latch member 30. Two securing portions 32 are formed on each side of the latch member 30.
Referring to FIG. 2, a cross section of the securing member 50 is U-shaped. Two slots 51 are defined in a side of the securing member 50. The slot 51 is defined to form a straight edge 511 and a bevel edge 512. A sliding block 52 projects adjacent to the slot 51. A plurality of resisting pieces 53 extends from a middle portion of the securing member 50. A positioning post 54 protrudes from a bottom portion of the securing member 50. A projection 55 is formed on each side of the securing member 50.
Referring to FIG. 3 and FIG. 4, three individual disk drives 20 are mounted in the bracket 10. The elastic component 40 is installed around the positioning piece 17. The securing portion 32 is inserted into the slot 51 of the securing member 50. The sliding block 52 is slid into the bent flange 16 of the bracket 10. The positioning post 54 is inserted in the elastic component 40. The securing portion 32 is laid on a bottom portion of the slot 51. The bent flange 16 resists against the projection 55. The bracket 10 is mounted in an electronic device with a cover 60.
Referring to FIG. 5, FIG. 6 and FIG. 7, the cover 60 is closed. The securing member 50 is moved along a first direction. The resisting piece 53 pushes the latch member 30 towards the bracket 10. The locking portion 31 of the latch member 30 is inserted into the mounting hole 21 of the disk drive 20. The securing portion 32 is slid along a top portion of the slot 51 adjacent to the straight edge 511. The elastic component 40 is compressed. The positioning post 54 resists against the positioning piece 17. The disk drive 20 is locked in the electronic device. The disk drive 20 is sandwiched between the corresponding pressing portions 141 and guide flanges 14.
When the cover 60 is removed, the securing member 50 is slid along a second direction by resilient force of the elastic component 40. The bevel edge 512 of the slot 51 pushes the securing portion 32 away from the disk drive 20. The latch member 30 is moved by the securing member 50 along a third direction perpendicular to the first direction. The locking portion 31 is disengaged from the mounting hole 21. The disk drive 20 is detached from the bracket 10.
It is to be understood, however, that even though numerous characteristics and advantages of the disclosure 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.
