## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a mounting apparatus, and more particularly to a mounting apparatus for a storage device.
2. Description of the Related Art
The manufacture and assembly of electronic apparatuses has become increasingly more competitive. Manufacturers continually strive to improve the design and features of electronic apparatuses yet still offer competitive prices. One such area of improvement is mounting of devices in an electronic apparatus. An electronic apparatus, such as a typical desktop computer, tower, server, and the like, usually include storage devices, such as hard disk drives, compact disk read-only memory (CD-ROM) drives, digital video disc (DVD) drives, floppy disk drives, and the like. These devices are typically added to increase the functionality of the electronic apparatus as desired by a user. However, the installation of such devices in the electronic apparatus is always labor-intensive.
For instance, the installation of a CD-ROM drive in a computer typically involves use of screws to attach the CD-ROM drive to a bracket of a computer chassis. Usually, these screws are small enough making them difficult to manipulate and install. It is laborious and time-consuming to manually manipulate the screws. Additionally, because of their small size, the screws are easier to be dropped by an assembler into the computer. Some accidental damage will occur in the computer due to impact of these moving parts, and the like causes.
To address the aforementioned problems, a plurality of mounting apparatuses is invented to reduce the number of needed screws. For example, a pair of detachable rails is attached to opposite sides of a storage device with screws. The storage device slides into and is secured to a drive bracket. However, the screws have to be removed to detach the rails from the storage device before replacing the storage device.
Another improved type of mounting apparatus without use of screws is disclosed in U.S. Pat. No. 5,599,080, which teaches a pair of mounting rails each having two horizontal projecting plug rods plugged into respective mounting holes in a storage device. An outward hook is formed on a front extension strip of each rail, for engagement with a respective retaining hole of a bracket to securely attach the storage device in the bracket. The extension strips are depressed inward to release the outward hooks from respective retaining holes, and therefore the storage device is able to be removed from the bracket. However, the storage device is apt to be unwillingly detached from the bracket due to inadvertently depressing the extension strips.
SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to provide a mounting apparatus which conveniently and securely holds a device in place.
To achieve the above object, a mounting apparatus in accordance with the present invention comprises a bracket for receiving a storage device. The storage device defines a plurality of apertures. An aperture is defined in a wall of the bracket. A plurality of holes is defined in the wall. A slidable member is movably attached to the wall of the bracket. A retention member is slidable relative to the slidable member in a first direction and a second direction generally perpendicular to the first direction. A plurality of latches is formed on the retention member. A switch member is pivotally attached to the wall of the bracket. When the switch member is located inside the bracket through the aperture of the bracket, the latches of the retention member are aligned with the holes of the bracket. When the switch member is driven outside the bracket by the storage device, the slidable member is urged by the switch member to move away from the switch member in the first direction, and the retention member is moved in the second direction to drive said latch through said hole for engaging in said aperture of the storage device.

DETAILED DESCRIPTION OF THE PRESENT INVENTION
Referring to FIGS. 1, 5, and 6, a mounting apparatus in accordance with the preferred embodiment of the present invention is provided for holding a storage device 90 in place. The storage device 90 comprises a pair of opposite sidewalls 91. One of the sidewalls comprises a plurality of apertures 92 defined therein. The mounting apparatus comprises a bracket 10, a slidable member 30, a retention member 50 and a switch member 70.
The bracket 10 comprises a pair of opposite sidewalls 12, 14. A pair of vertically spaced rails 121, 141 is punched inwardly from respective sidewalls 12, 14, for supporting storage device 90 therebetween. Two horizontally spaced projections 123 are formed on an outer surface of the sidewall 12, each projection 123 having an internal thread. A pair of vertically spaced holes 125 is defined in the sidewall 12 adjacent to each projection 123. An aperture 126 is defined in the sidewall 12 adjacent to a rear end thereof. A pair of tabs 127 is bent perpendicularly outwardly from upper and lower extremities of the aperture 126. A pair of pivot holes 1271 is defined in the tabs 127 respectively. Two pairs of flexible flanges form in the sidewalls 12 near the top and bottom of the bracket 10 and extend into the bracket 10 to define a pathway therebetween so as to allow the device 90 to move along.
The slidable member 30 is generally a frame with a lateral opening defined therein. The slidable member 30 comprises a pair of parallel longitudinal rims 31, and a pair of slideways 311 is defined in a surface of each longitudinal rim 31 adjoining the opening. Each slideway 311 comprises a first shoulder portion 3111, an indentation 3112 and a second shoulder portion 3113. Each of the first and second shoulder portions 3111, 3113 has a vertical planar surface, and the indentation 3112 has an arcuate surface. A pair of vertical rims 32, 33 connect between two ends of the pair of longitudinal rims 31 respectively. A connecting rod 331 is formed on the vertical rim 33.
The retention member 50 comprises a rectangle plate 51, and a pair of flanges 53 extended perpendicularly outwardly from upper and lower edges of the plate 51. A pair of circular posts 511 is punched perpendicularly outwardly from the plate 51. Each post 511 defines an internal through-hole, corresponding to each projection 123 of the bracket 10. Two orthogonal latches 513 are bent inwardly from near each end of the plate 51, corresponding to apertures 92 of the storage device 90. A pair of arcuate sliding portions 531 is formed on each flange 53, corresponding to slideways 311 of the slidable member 30.
A pair of fasteners such as screws 60 is provided to attach the retention member 50 to the sidewall 12 of the bracket 10 by cooperating with a pair of resilient members such as coil springs 40.
The switch member 70 comprises a pair of pivots 71 protruding outwardly from top and bottom surfaces thereof respectively. The pivots 71 correspond to pivot holes 1271 of the bracket 10.
In assembly of the mounting apparatus, the slidable member 30 is aligned with the sidewall 12 of the bracket 10, and the projections 123 of the bracket 10 are shown out through the opening of the slidable member 30. The retention member 50 is received in the opening of the slidable member 30, with the projections 123 extended beyond the posts 511 of the retention member 50 through the through-holes thereof respectively. The sliding portions 531 of the retention member 50 are slidably engaged with corresponding slideways 311 of the slidable member 30. The screws 60 are screwed in the projections 123 of the bracket 10, and the coil springs 40 are interposed between the plate 51 of the retention member 50 and the screws 60 respectively. The switch member 70 is pivotally attached to the tabs 127 of the bracket 10. Another coil spring 80 connects between the connecting rod 331 of the slidable member 30 and the switch member 70.
In use of the mounting apparatus, referring particularly to FIG. 2, FIG. 2 shows the slidable member 30 is in a first position. The sliding portions 531 of the retention member 50 are engaged with the first shoulder portions 3111 of the slideways 311 of the slidable member 30 respectively, and the retention member 50 is situated farmost relative to the sidewall 12 of the bracket 10. The latches 513 of the retention member 50 are aligned with the holes 125 of the sidewall 12 respectively. The coil springs 40 are in a compressed state. The switch member 70 is generally wholly rotated inward the bracket 10 through the aperture 126 thereof, and the coil spring 80 (not visible) is in a normal state. The vertical rim 33 abuts the rest portion of the switch member 70 that stays outside the bracket 10.
The storage device 90 is then slid into the bracket 10 along the rails 121, 141. The storage device 90 contacts and gradually drives the switch member 70 to rotate outwardly until the switch member 70 is rotated generally fully out of the bracket 10, such that the switch member 70 drives the slidable member 30 forwardly to a second position shown in FIG. 3. During movement of the slidable member 30, the sliding portions 531 of the retention member 50 are relatively slid from the first shoulder portions 3111 of the slideways 311 of the slidable member 30 to the indentations 3112, and the coil springs 40 restore to push the retention member 50 toward the sidewall 12 of the bracket 10 at the indentations 3112. The latches 513 of the retention member 50 are generally fully extended into corresponding apertures 92 of the storage device 90 through corresponding holes 125 of the sidewall 12 of the bracket 10. The storage device 50 is thus fixed in the bracket 10 (see FIG. 5). The coil spring 80 is slightly stretched out.
Referring to FIG. 4, to detach the storage device 90 from the bracket 10, the slidable member 30 is pushed further forwardly to a third position. The sliding portions 531of the retention member 50 are relatively slid from the indentations 3112 of the slideways 311 of the slidable member 30 to the second shoulder portions 3113, and the latches 513 are withdrawn from the apertures 92 of the storage device 90 (not shown in FIG. 4). The coil springs 40 are compressed, and the coil spring 80 is stretched further out. The storage device 90 is then ready to be removed form the bracket 10. After the storage device 90 is removed from the bracket 10, the coil spring 80 restores to draw the slidable member 30 to the first position shown in FIG. 2.
While the present invention has been illustrated by the description of the preferred embodiment thereof, and while the preferred embodiment has been described in considerable detail, it is not intended to restrict or in any way limit the scope of the appended claims to such detail. Additional advantages and modifications within the spirit and scope of the present invention will readily appear to those skilled in the art. Therefore, the present invention is not limited to the specific details and illustrative examples shown and described.
