## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application is related to co-pending U.S. patent application entitled “RETAINING APPARATUS FOR DATA STORAGE DEVICES”, application Ser. No. 12/534,215, Application date Aug. 3, 2009.
BACKGROUND
1. Technical Field
The disclosure generally relates to a retaining apparatus for data storage devices, especially to a retaining apparatus with a tray for receiving and retaining at least one data storage device.
2. Description of Related Art
Typically, a data storage device, such as a hard disk drive is simply screwed to a computer enclosure. This conventional mounting means can be complex, difficult and substantially wastes time. In addition, in use, vibration of the data storage device may cause the screws to come loose and may result in damage to the data storage device. Understandably, some attempts have been taken to introduce a mounting apparatus for a data storage device without screws.

DETAILED DESCRIPTION
Referring to FIG. 7, a bracket 200 is used in a computer or an electronic device for mounting at least one retaining apparatus for data storage device 100. The bracket 200 includes two parallel side plates 21. A slideway is defined between the two side plates 21 for receiving the retaining apparatus. One of the side plates 21 defines a rectangular retaining opening 220.
Referring to FIG. 1 and FIG. 2, each retaining apparatus includes a tray 30 and a retaining device 10.
The retaining device 10 includes a base member 11, a retaining member 13, an arm member 15, and a locking member 17.
The base member 11 defines a pair of pivot holes 1132 at one end thereof. A pivot shaft 19 extends through the two pivot holes 1132 to define a pivot axis. The base member 11 includes a top wall 112, a bottom wall 113, and two opposite sidewalls 117. The top wall 112, the bottom wall 113 and the sidewalls 117 are enclosed to from a cavity 111 to receive the retaining member 13, the arm member 15, and the locking member 17. A channel 1173 is defined at one of the sidewall 117 of the base member 11. A latch 116 protrudes from the base member 11 in the cavity 115.
The retaining member 13 is movably attached to the base member 11 along a first direction. The retaining member 13 includes an engaging portion 137 and a retaining portion 135. The engaging portion 137 includes a plurality of engaging teeth.
Referring to FIG. 3, the locking member 17 includes a main body 171, an end portion 172, a latching portion 176 protruding from the main body 171, two restricting tabs 174, two resilient catches 175 and two posts 178. The main body 171 has a plate like configuration. The catches 175 are placed at two opposite side of the main body 171. The catches 175 and the main body 171 are positioned on a same plane. An opening 173 is defined in the main body 171 adjacent to the latching portion 176. The latching portion 176 partly covers the opening 173 so that the latch 116 can move into the portion of the opening 173 and engage with the latching portion 176.
The arm member 15 defines a pivot hole 1513 corresponding to the pivot shaft 12 and has a driving portion 151 corresponding to the engaging portion 137. The driving portion 151 has a plurality of driving teeth to mesh with the engaging teeth of the engaging portion 137. The arm member 15 defines a receiving space 155 for receiving the locking member 17. Two first blocks 157 and two second blocks 158 are formed on the arm member 15 and correspond to the restricting tabs 174 and the catches 175. The first blocks 157 can restrict movement of the locking member 17 to prevent movement into the arm member 15.
Referring to FIG. 4, when assembling the locking member 17 to the arm member 15, the locking member 17 is moved into the receiving space 155 of the arm member 15. Two coil springs 16 are located between the locking member 17 and the arm member 15. The coil springs 16 are compressed and provide ejection force to move the locking member 17 away from the arm member 15. The catches 175 are hooked on the second blocks 158 for holding the locking member 17 in the arm member 15. The end portion 172 extends from a free end of the arm member 15.
Referring through FIG. 5 to FIG. 6, when assembling the retaining apparatus, the base member 11 is mounted to the tray 30. The retaining member 13 is moved into the cavity 111 of the base member 11. The arm member 15 is pivotably fixed to the base member 11 about the pivot axis, and the driving portion 151 meshes with the engaging portion 137. The arm member 15 then is rotated relative to the retaining member 13 so that the retaining portion 135 resides in the cavity 111 of the base member 11.
Referring to FIG. 7 and FIG. 10, when mounting the retaining apparatus into the bracket 200, the tray 30 and the retaining device 10 are completely slid into the slideway of the bracket 200 with the channel 1173 aligned with the retaining opening 220. Then the arm member 15 is urged to rotate toward the base member 11, and drives the retaining portion 135 to move out of the channel 1173 to engage with the side plate 21 at the retaining opening 220. When the free end of the arm member 15 reaches the base member 11, the latch 116 moves into the opening 173 and engages with the latching portion 176 of the locking member 17. The retaining apparatus is thus mounted to the bracket 100.
When removing the retaining apparatus from the bracket 100, the locking member 17 is pressed on the end portion 172. The latch 116 is disengaged from the latching portion 176. Then, the arm member 15 is rotated outwardly from the base member 11. The retaining portion 135 moves into the cavity 111 of the base member 11 and disengages from the side plate 21 of the bracket 200. The retaining apparatus then is capable of being moved out of the bracket 200.
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.
