## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to mounting apparatuses, and more particularly to a mounting apparatus for securing a power supply in a computer system.
2. Description of Related Art
In a computer system, a power supply is usually provided and secured with a mounting apparatus. For example, the mounting apparatus includes a chassis and a bracket. The chassis includes a rear panel and a side panel, respectively forming a plurality of supporting plates to support the power supply thereon. The rear panel defines a slot and the side panel defines a pair of locking apertures therein, and the bracket includes a first plate and a second plate. The first plate forms a hook corresponding to the slot of the chassis. The second plate forms a pair of resilient catches corresponding to the locking apertures of the chassis. In assembly, the power supply is placed on the supporting plates of the rear panel and the side panel. The hook of the first plate is rotatably engaged into the slot of the rear panel. The catches of the second plate are locked into the locking apertures of the side panel. Thus, the power supply is secured on the rear panel and the side panel of the chassis.
In the mounting apparatus described above, it is convenient to secure the power supply in the chassis. However, in some computer systems, more particularly in some mini computer systems, due to the very small inner space, it is needed to remove the power supply before removal, maintenance, and checking of electronic elements in the chassis, which is very inconvenient.
What is needed, therefore, is a mounting apparatus for a power supply which allows convenient removal, maintenance, and checking of electronic elements in a chassis of a computer system.

DETAILED DESCRIPTION OF THE INVENTION
Referring to FIG. 1, a mounting apparatus of a preferred embodiment of the present invention includes a chassis 10 of a computer system, a bracket 20 for receiving a power supply 50 (shown in FIG. 3) therein, and a connecting device 30 connected the chassis 10 and the bracket 20.
The chassis 10 has a plate 12 with an opening 122 defined therein. A plurality of resilient fingers 124, 125 extends from top and bottom edges of the opening 122. Protrusions 1242, 1252 are formed on end portions of the resilient fingers 124, 125, respectively. Two securing pieces 126 are perpendicularly bent in from two opposite side edges of the opening 122 respectively. Two pivot holes 1262, 1264 are respectively defined in each securing piece 126. The pivot hole 1262 is positioned above the pivot hole 1264. A bent flange 128 and a retaining flange 129 parallel to the bent flange 128 are formed on a top portion of the plate 12 above the opening 122. The bent flange 128 is adjacent to and above the opening 122. Two cutouts 1282 are defined in the bent flange 128 connecting the opening 122, respectively adjacent the securing pieces 126. A plurality of spaced positioning holes 1292 is defined in the retaining flange 129.
The bracket 20 includes a bottom wall 22, and two side walls 24 perpendicular to the bottom wall 22. An opening 222 is defined in the bottom wall 22, corresponding to the opening 122 of the plate 12 of the chassis 10. A plurality of mounting holes 224 is defined in the bottom wall 22. A support flange 226 is perpendicularly bent out from an edge of the bottom wall 22. Each side wall 24 defines two pivot holes 242, 244 therein.
The connecting device 30 includes a pair of first members 32, and a pair of second members 34. The first members 32 are generally L-shaped, and each defines two pivot holes 322, 324 in two end portions respectively. The second members 34 are generally step-shaped, and each defines two pivot holes 342, 344 in two end portions respectively.
Referring also to FIG. 2, in assembly, the first members 32 of the connecting device 30 are placed between and respectively attached to adjacent sides of the securing pieces 126 of the plate 12. The pivot holes 322 of the first members 32 align with the pivot holes 1262 of the securing pieces 126, respectively. Two securing members (not shown), such as screws or rivets, are secured into the pivot holes 322, 1262, thereby rotatably securing the first members 32 on the securing pieces 126. The second members 34 are respectively attached to other sides of the securing pieces 126 of the plate 12. The pivot holes 342 of the second member 34 align with the pivot holes 1264 of securing pieces 126, respectively. Two securing members (not shown), such as screws or rivets, are secured into the pivot holes 342, 1264, thereby rotatably securing the second members 34 on the securing pieces 126. The bracket 20 is placed in the chassis 10. The first members 32 and the second members 34 are positioned on outer sides of the side walls 24 of the bracket 20, respectively. The pivot holes 324 of the first members 32 align with the pivot holes 242 of the side walls 24. The pivot holes 344 of the second members 34 align with the pivot holes 244 of the side walls 24. Securing members (not shown), such as screws or rivets, are secured into the pivot holes 242, 324 and the pivot holes 244, 344. So that the first and second members 32, 34 are rotatably secured on the side walls 24. The bracket 20 thus connects the plate 12 with the connecting device 30. The first and second members 32, 34 can be rotated synchronously relative to the securing pieces 126 of the plate 12, and the side walls 24 of the bracket 20.
Referring also to FIG. 3, the power supply 50 is placed into the bracket 20. The mounting holes 224 of the bottom wall 22 align with the mounting holes (not shown) defined in the power supply 50. A plurality of securing members (not shown), such as screws, is screwed into the mounting holes 224 of the bottom wall 22 and the mounting holes of the power supply 50. The power supply 50 is thus secured into the bracket 20.
The power supply 50 has a horizontal position (shown in FIG. 4) and a vertical position (shown in FIG. 5), and can be moved from the horizontal position to the vertical position. When the power supply 50 is positioned in the horizontal position, the bottom wall 22 of the bracket 20 abuts on and generally parallel to an inner surface of plate 12 of the chassis 10 and the power supply 50 is substantially located within the chassis 10. The support flange 226 of the bracket 20 abuts on the retaining flange 129 of the plate 12 of the chassis 10. A plurality of positioning tabs (not shown) formed on the support flange 226 engages into the positioning holes 1292 of the retaining flange 129 to stably position the power supply 50 in the horizontal position. The protrusions 1242, 1252 of the resilient fingers 124, 125 of the plate 12 electrically abuts on the bottom wall 22 of the bracket 20, thereby protecting the computer system from static interference. When the power supply 50 is positioned in the vertical position, the bottom wall 22 of the bracket 20 abuts on the retaining flange 129 and generally perpendicular to the plate 12 and the power supply 50 is substantially located at outside of the chassis 10. For removal, maintenance, and checking of electronic elements in the chassis 10, the power supply 50 is moved from the horizontal position to the vertical position.
Furthermore, when the power supply 50 is positioned in the vertical position, the first members 32 are engaged into the cutouts 1282 of the bent flange 128 of the plate 12, thereby preventing blocking of the first members 32 when the bracket 20 is moved to the vertical position.
Furthermore, the bracket 20 also has a horizontal position and a vertical position, corresponding to that of the power supply 50. The bottom wall 22 in the horizontal position is perpendicular to the bottom wall 22 in the vertical position.
Furthermore, the first members 32 are L-shaped in order to not be blocked by the retaining flange 129 of the plate 12 when the power supply is moved to the vertical position. The second members 34 are step-shaped in order to not interfere with the securing pieces 126 and the first members 32 when the power supply 50 is moved.
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.
