1. Field of the Invention
The present invention relates to a computer enclosure, and more particularly to a mounting mechanism which facilitates assembly of a computer cover to a computer enclosure.
2. Background of the Invention
In order to mount electronic components into a computer conveniently, an opening is usually defined in a computer enclosure. The electronic components such as hard disk, CD-ROM, get through the opening and are secured therein. Then, a side plate is mounted on the computer enclosure to cover the opening.
Previously, the side plate of the computer is typically secured to the computer enclosure by retaining screws. In the process to mount or demount components in the computer enclosure, it is necessary to remove the individual retaining screw firstly. However, there are a plurality of screws fastened in the computer enclosure. It is boring to manipulate the screws frequently. Furthermore, the tiny screw will be easily lost or dropped into other electronics of the computer. If not removed carefully, the presence of a screw can cause electronic or physical damage to the computer electronics.
Accordingly, what is needed is a mounting mechanism which facilitates assembly of a computer cover to a computer enclosure.
A computer enclosure according to a preferred embodiment of the present invention includes a chassis having a blocking portion and a cover attached to the chassis. A handle having a pressing tab is attached to the cover. A locking block is locked with the blocking portion to secure the cover to the chassis. The locking block includes an inclined face for the pressing tab sliding therealong. When the handle is pulled, the locking block is disengaged from the blocking portion of the chassis.
Other objects, advantages and novel features of the present invention will be drawn from the following detailed description of preferred embodiments of the present invention with the attached drawings, in which:
Referring to
The cover 10 includes a flange 11 protruding from one edge and a plate 12 extending inwardly from the other. A rectangular receiving recesss 13 is defined in the cover 10. A pair of securing slots 131 are defined in the recess 13. A rectangular opening 15 is defined between the two securing slots 131. A post 17 adjacent to the opening 15 protrudes inwardly from the inner side of the cover 10. A pair of opposite hooks 19 protrudes respectively from two sides of the post 17. A sliding slot 18 is formed beside each hook 19.
The handle 20 includes a base 21 and a flange 22 formed therefrom. The base 21 sinks inwardly and forms a holding portion 23. A plurality of catches 25 corresponding to the securing slots 131 protrudes from a bottom of the base 21. An L-shaped pressing tab 26 corresponding to the opening 15 of the cover 10 extends backwardly from the bottom of the base 21. A post 27 protrudes from the side wall of the base 21. A first spring 30 is disposed around the post 27.
The locking block 50 is wedge-shaped, and includes a protuberance 55. The locking block 50 has a pair of parallel side faces 51 and an inclined face 53. A ridge 57 corresponding to the sliding slot 18 extends through the side face 51. A securing notch 58 in correspondence with the hook 19 is defined at a corner of the side face 51. A hollow 59 is formed in the bottom of the locking block 50 for receiving one end of a second spring 40. The other end of the second spring 40 is disposed around the post 17.
The chassis 60 includes a front panel 61 and a rear panel 65. A flange 63 extends backwardly from a side edge of the front panel 61. A blocking portion 67 corresponding to the locking block 50 protrudes inwardly from the rear panel 65.

Referring to
In disassembly, pulling the handle 20 backwardly in the receiving recess 13, the pressing tab 26 is slid along the inclined face 53 towards the protuberance 55 until the locking block 50 is pressed to move outwardly. The locking block 50 is retracted to avoid the blocking portion 67. Pulling the cover 10 backwardly, the cover 10 is disassembled from the chassis 60. At this time, the handle 20 and the locking block 50 come back to the initial state respectively for the next operation due to the spring 30 and 40.
It is believed that the present invention and its advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the examples hereinbefore described merely being preferred or exemplary embodiments of the invention.
