DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Refer to FIG. 1 and FIG. 2, a bezel of an electronic device like a computer in accordance with a preferred embodiment of the present invention includes a main body 100, a shutter 10 which is movably attached to the main body 100, a pair of resilient components such as springs 50, and a bracket 40. A speed control mechanism is also formed in the bezel.
The main body 100 is often rectangular, and mounted on a front surface of a computer chassis (not shown). An opening 110 is defined in the main body 100 for mounting internal devices of the computer, for example, read/write devices such as storage drivers (not shown) and I/O interface components (not shown). A flange 103 extends inwardly from each side of the opening 110. A first rail 120 and a second rail 130 are aligned uprightly in each flange 103. Each first rail 120 includes a guiding rail 122 parallel with the main body 100, and an orientating rail 124 extending from one end of the guiding rail 122 and slanting towards the main body. Each second rail 130 also includes a guiding rail 132 and an orientating rail 134 extending from one end of the guiding rail 132 and slanting towards the main body 100. A pair of posts 126 with screw holes (not labeled) is formed on the main body 100 nearby each side of the flange 103. A gear 152, as a part of the speed control mechanism, is secured on the main body 100 under the opening 110. A pair of posts 160 is aligned uprightly at the main body 100 at one side of the gear 152. A pair of guiding tabs 140 is formed at the main body 100 between the gear 152 and the posts 160. A locking device such as, for example, a door lock 170 is secured on the main body 100 under the guiding tabs 140. A post (not shown) with screw holes is formed on the main body 100 over an outside of each flange 103.
The shutter 10 includes a cover 11 whose size is fit for the opening 110. A side plate 20 extends inwardly from each side of the cover 11. A first sliding portion 22 corresponding to the first rail 120 and a second sliding portion 24 corresponding to the second rail 130 are formed on each side plate 20. A hook 26 is formed on each first sliding portion 22. A sliding bar 32 extends from a middle portion of a bottom of the cover 11. A rack 34, as the other part of the speed control mechanism, is formed along one side edge of the sliding bar 32 corresponding to the gear 152 of the main body 100. A barbed engaging end 36 extends from a bottom of the sliding bar 32 corresponding to the door lock 170 of the main body 100. The front surface of the shutter 10 has an operating member 12 such as, for example, a recess.
The bracket 40 for baffling the shutter 10 to be pushed away from the main body 100 is often rectangular corresponding to the opening 110 of the main body 100. The bracket 40 has a bigger opening 42 for floppy discs and a smaller I/O interface opening 44. A fastening piece 48 with a fastening hole 46 protrudes outwardly from each side of the bracket 40 corresponding to each post 126 of the main body 100.
Each spring 50 includes clasps 52, 54 extending from distal ends thereof, respectively.
Refer to FIGS. 3-5, in assembly, firstly, the clasp 52 of each spring 50 is mounted to the post of the main body 100 via screw. The clasp 54 of each spring 50 is engaged with the corresponding hook 26 of the shutter 10. Then the shutter 10 is mounted to the main body 100. The first sliding portion 22 is positioned in the guiding rail 122 of the first rail 120 of the main body 100. The second sliding portion 24 is positioned in the guiding rail 132 of the second rail 130 of the main body 100. The sliding bar 32 of the shutter 10 is positioned between the gear 152 and the posts 160 of the main body 100. At the time, the rack 34 of the sliding bar 32 is meshed with the gear 152. Finally, a screw (not shown) is passed through a corresponding fastening hole 46 of the bracket 40 and engages in a corresponding screw hole of the post 126 of the main body 100. Thus the bracket 40 is secured to the inside of the main body 100 and restricts the shutter 10.
When the first sliding portion 22 and the second sliding portion 24 of the shutter 10 are at bottom ends of the guiding rails 122, 124 which are away from the orientating rails 124, 134, the shutter is opened. Thus the opening 110 of the main body 100, the bigger opening 42 and the smaller I/O interface opening 44 of the bracket 40 are available. At the time, the sliding bar 32 of the shutter 10 is on the top of the guiding tabs 140 so that the shutter is spaced with the main body 100 and accommodated in to the inner side of the main body 100. The engaging end 36 of the shutter 10 is engaged into the door lock 170 of the main body 100, and the springs 50 are extended, as shown in FIG. 3.
When the shutter is pressed downwardly via pressing the recess 12, the engaging end 36 of the shutter 10 is ejected from the door lock 170. Then the first sliding portion 22 and the second sliding portion 24 slide upwardly along the first guiding rail 122 and the second guiding rail 132 respectively due to the resilience of the springs 50. At the time, the rack 34 and the gear 152 are operative together. Since the first sliding portion 22 and the second sliding portion 24 slide into the orientating rails 124, 134, the shutter 10 slides into the opening 110 of the main body 100 along the slope of the guiding tabs 140 so that the shutter 10 is in the same plane with the front surface of the main body 100. Thus it is possible to achieve appropriate dustproof effect, as shown in FIGS. 1 and 5.
In opening the shutter 10, the shutter 10 is pressed via pressing the recess 12, then the first sliding portion 22 and the second sliding portion 24 slide into the first guiding rail 122 and the second guiding rail 132 respectively, and the sliding bar 32 slides onto the top of the guiding tabs 140. At the time, the rack 34 and the gear 52 are operative together until the engaging end 36 is engaged into the door lock 170. Thus the shutter 10 is opened and the opening 110 of the main body 100 is uncovered.
During the opening and closing process of the shutter 10, the associated operation of the rack 34 and the gear 52 provide mitigation for the movement of the shutter 10.
Furthermore, it is possible that the first rail 120 and the second rail 130 include only orientating rails which extend slantways.
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.
