## Background
FIELD OF THE INVENTION
The present invention relates to computer enclosures, and more particularly to a computer enclosure having a removable bezel.
DESCRIPTION OF RELATED ART
In a conventional computer enclosure, a decorative bezel is usually secured to the computer enclosure.
A mounting means is provided in a computer enclosure which includes a bezel and a plate. A pair of symmetrically opposing pivots is formed on the bezel. A pair of L-shaped bearings is forwardly formed from a bottom portion of the plate. When the bezel is attached to the plate, the pivots of the bezel are pivotally received in the bearings of the plate. The bezel is rotated toward the plate about the pivots. Clasps of the bezel are inserted into slots defined in the plate, and hooks of the plate snappingly engage in engaging apertures defined in the clasps. Thus the bezel fully abuts the plate, and is securely attached thereon. However, it is inconvenient to remove the bezel from the computer enclosure when it is mounted in this way.
Another mounting means is provided in a bezel mounting assembly which includes a bezel, a plate, a lock member, and an operating member attached to the plate. The plate has a plurality of slits, two locking apertures, and a through hole. The bezel forms a plurality of hooks engagingly received in the slits of the plate. The lock member includes a central beam, two side plates, and a resilient portion attached to the bezel and biasing the central beam. Each side plate includes a catch engagingly received in each locking aperture of the plate. The operating member includes a drive body and a press body. When the drive body is pressed downwardly, the press body is rotated to press the central beam downwardly. The catches and the hooks are thereby released from engagement. Then the bezel is fully detached from the plate. In this mounting means, it is convenient to remove the bezel, but the structure thereof is very complicated.
What is needed, therefore, is a computer enclosure having a conveniently removable bezel with a simple structure.
SUMMARY OF THE INVENTION
A computer enclosure includes a chassis, a bezel, and a detaching member. The chassis has a plate defining at least one locking aperture therein. The bezel is attachable to an outer surface of the plate. At least one hook protrudes from the bezel for engaging into the at least one locking aperture and extending into the chassis. The detaching member is rotatably attached to an inner surface of the plate for outwardly pushing the bezel. At least one pushing portion is formed on the detaching member for abutting against the at least one hook. Before the detaching member is rotated to outwardly push and separate the bezel away from the plate, the at least one pushing portion presses the at least one hook to release from the at least one locking aperture.

DETAILED DESCRIPTION OF THE INVENTION
Referring to FIG. 1, a computer enclosure of a preferred embodiment of the present invention includes a chassis 10, a bezel 20, and a detaching member 30.
The chassis 10 has a plate 12 defining two rectangle connecting apertures 121 and a plurality of locking apertures 122, 123, 124 along a longitudinal direction respectively in right, middle and left portions thereof. Two circled securing holes 125 are defined in the plate 12. A hollow pivot post 126 protrudes in from the left portion of the plate 12. A pair of arc-shaped slots 127, 128 is defined in both sides of the pivot post 126. Each of the slots 127, 128 includes a wide portion (not labeled) and a narrow portion (not labeled). A through opening 129 is defined among the locking aperture 123, the slots 127, 128, and the pivot post 126. A slanted tab 130 protrudes in from the plate 12 at a left side of the locking aperture 124 and below the slot 128. The tab 130 has a free end adjacent the locking aperture 124. A flange 14 is perpendicularly bent from a top edge of the plate 12. A rectangle through hole 142 is defined in a left portion of the flange 14.
The bezel 20 is attachable to the plate 12 of the chassis 10. Two connecting pieces 22 and a plurality of hooks 24, 25, 26 protrude in from the bezel 20 along the longitudinal direction, respectively corresponding to the locking apertures 121, 122, 123, 124 of the plate 12. The connecting pieces 22 have free ends bent right therefrom. The hooks 24, 25 have hook portions formed at right sides of free ends thereof. The hook 26 has a hook portion formed at a left side of a free end thereof. Two positioning posts 28 protrude in from a middle of the bezel 20, configured for inserting into the securing holes 125 of the plate 12 to position the bezel 20 with respect to the plate 12. Each positioning post 28 defines a cutout 282 therein for easily deforming. A rib 29 with a slanted surface 292 is formed at a left end of the bezel 20.
Referring to FIGS. 1 and 2, the detaching member 30 is rotatably attached to an inner surface of the plate 12. A pivot hole 31 is defined in the detaching member 30, for receiving the pivot post 126 of the plate 12. A pair of pushing portions 32, 33 is bent in from two sides of the pivot holes 31, corresponding to the hooks 25, 26 of the bezel 20. Each of the pushing portions 32, 33 has a surface fitted with a surface of the hook portion of the corresponding one of the hooks 25, 26. A pair of L-shaped sliding portions 34, 35 protrudes out from the two sides of the pivot holes 31, corresponding to the slots 127, 128 of the plate 12. An operating portion 38 is perpendicularly bent in from the detaching member 30 between the pushing portion 32 and the sliding portion 34, for engaging in the through hole 142 of the flange 14 of the plate 12. A protrusion 36, which has an arc-shaped outer surface, is formed out from the detaching member 30, corresponding to the slanted surface 292 of the rib 29 of the bezel 20.
Referring also to FIG. 3, before assembly of the bezel 20, the detaching member 30 is placed in the chassis 10. The pivot hole 31 aligns with the pivot post 126 of the plate 12. The sliding portions 34, 35 align with the wide portions of the slots 127, 128. The protrusion 36 aligns with the through opening 129. The detaching member 30 is pushed to attach to the inner surface of the plate 12. The pivot post 126 is rotatably received in the pivot hole 31. The sliding portions 34, 35 insert into the wide portions of the slots 127, 128. The protrusion 36 inserts through the through opening 129 of the plate 12, and extends out of the chassis 10. The tab 130 is pressed by the detaching member 30, and thereby resiliently deforms. Referring also to FIG. 4, the detaching member 30 is then rotated counter-clockwise. The operating portion 38 is inserted into the through hole 142 of the flange 14 of the plate 12. The sliding portions 34, 35 slide in the slots 127, 128 from the wide portions to the narrow portions to pivotably engage with the plate 12 at the narrow portions, thereby preventing the sliding portions 34, 35 releasing from the plate 12, along a direction perpendicular to a plane of the plate 12. The tab 130 is released from the detaching member 30, and rebounds to block the sliding portions 34, 35 sliding reversely from the narrow portions to the wide portions of the slots 127, 128. Thus, the detaching member 30 is rotatably secured to the inner surface of the plate 12 of the chassis 10.
Referring also to FIG. 5, in assembly of the bezel 20, the connecting pieces 22 of the right portion of the bezel 20 are inserted into the corresponding locking apertures 121 of the plate 12. The bezel 20 is then pivoted toward the plate 12 by pushing the left portion thereof, until the hooks 24, 25, 26 and the positioning posts 28 respectively engage into the locking apertures 122, 123, 124, and the securing holes 125 of the plate 12. The hooks 25, 26 extend through the locking apertures 123, 124, and abut against the pushing portions 32, 33 of the detaching member 30. The protrusion 36 of the detaching member 30 abuts against the slanted surface 292 of the rib 29 of the bezel 20. Thus, the bezel 20 is secured to the outer surface of the plate 12 of the chassis 10.
In removal of the bezel 20, the operating portion 38 is pushed via the through hole 142 of the flange 14 to counter-clockwise rotate the detaching member 30. The pushing portions 32, 33 of the detaching member 30 press the hooks 25, 26 in directions parallel to the plane of the plate 12 to release from the locking apertures 123, 124. At the same time, the protrusion 36 of the detaching member 30 pushes the slanted surface 292 of the rib 29 of the bezel 20 outward. The bezel 20 is thereby pivoted out away from the plate 12. The hooks 25, 26 are pulled out of the locking apertures 123, 124. The hooks 24 and the positioning posts 28 are pulled out of the locking apertures 122 and the securing holes 125, respectively. The connecting pieces 22 can be thereby removed from the locking apertures 121. Thus, the bezel 20 is removed from the plate 12 of 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.
