Referring again to FIG. 5, the computer housing-and-lock assembly 10 further includes an urging member 71 that has two opposite ends secured to the latch members 50, 60 for restoring the latch members 50, 60 from the stopped position to the non-stopped position when the driving member 30 is moved from the second lateral position to the first lateral position. It should be noted herein that, in the second preferred embodiment as shown in FIG. 9, the computer housing-and-lock assembly 10 may include a pair of urging members 72, 73, each of which has one end secured to the top cover 13, and an opposite end secured to a respective one of the latch members 50, 60 for urging the latch members 50, 60 to restore from the stopped position to the non-stopped position when the driving member 30 is moved from the second lateral position to the first lateral position.
Referring again to FIGS. 2 and 6, each of the slides 81 is provided with an operating protrusion 82 protruding therefrom. Each of the lateral walls 14, 15 is further formed with an elongated slot 18 for extension of the operating protrusion 82 of a respective one of the slides 81 therethrough so that movement of the slides 81 can be manually operated through the respective operating protrusion 82.
With further reference to FIGS. 4 and 6, a pair of U-shaped guide members 24 are respectively mounted on inner sides 141, 151 of the lateral walls 14, 15 of the top cover 13 and are aligned with the elongated slots 18. Each of the guide members 24 includes a guide plate 241 that is spaced apart from the corresponding inner side 141, 151 of the lateral walls 14, 15, that is formed with a U-shaped opening 242, and that has a hook piece 243 spaced apart from the opening 242. Each of the slides 81 is movably retained in a clearance between the guide plate 241 and the corresponding inner side 141, 151 of the lateral walls 14, 15, and is provided with a screw 83 projecting therefrom, and a spring 85 having one end secured to the hook piece 243, and an opposite end secured to the screw 83 for urging the slide 81 to move from the unlocked position to the locked position. Referring again to FIGS. 2 and 4, in order to guide movement of the second interlocking members 84 to engage the first interlocking members 863 during movement of the top cover 13 from the opened position to the closed position, each of the second interlocking members 84 is designed to have a round shape, and each of the retaining plates 86 is designed to have an arcuate edge 865 extending from an upper edge of a groove-defining wall defining the end groove of the respective first interlocking member 863.
Referring again to FIG. 6, the top cover 13 is provided with a pair of spaced apart limiting blocks 21 disposed adjacent to the rear wall 130 of the top cover 13. The driving member 30 further includes an actuating piece 31 that has a portion disposed movably between and in sliding contact with the limiting blocks 21, and that is connected to the driving plate 32, and a hook stud 33 protruding from the driving plate 32. It is noted that operation of the actuating piece 31 is conducted using a key (not shown) so that the movement of the stoppers 52, 62 from the stopped position to the non-stopped position can be achieved solely by the key. A biasing member 40, which is a compression spring in this embodiment, has opposite ends secured respectively to the hook stud 33 and a hook member 19 protruding from the top cover 13 for providing a biasing force to urge the driving member 30 to move from the second lateral position (see FIG. 7) to the first lateral position (see FIG. 6).
Referring again to FIGS. 5 and 6, the top cover 13 further has a front wall 17 (see FIG. 6) that is formed with a pair of limiting posts 22. The latch member 50 is formed with a pair of elongated guiding slots 53 for extension of the limiting posts 22 respectively therethrough so as to guide movement of the latch member 50 along the second axis (Y).

Each of the driven ends 51, 61 of the latch members 50, 60 is provided with a hook element 54, 63 for mounting the urging member 71.
At the normal condition, as shown in FIGS. 5 and 6, the latch members 50, 60 are disposed at the non-stopped position, i.e., the stoppers 52, 62 are respectively misaligned with the slides 81.along the first axis (X). Hence, opening and closing of the top cover 13 can be conducted through operation of the slides 81. As shown in FIG. 8, when it is desired to close the top cover 13, the top cover 13 is pivoted relative to the base 11 toward the closed position such that the second interlocking members 84 engage respectively the first interlocking members 863 through guidance of the arcuate edges 865 of the retaining plates 86 so as to retain the top cover 13 at the closed position. When it is desired to open the top cover 13, the slides 81 are moved frontwardly so as to disengage the second interlocking members 84 from the first interlocking members 863 such that the top cover 13 can be pivoted upward to the opened position.
As shown in FIGS. 7 and 8, the top cover 13 can be locked using the key (not shown) such that the stoppers 52, 62 are retained at the stopped position to prevent movement of the slides 81 from the locked position to the unlocked position. Hence, when it is desired to open the top cover 13, the actuating piece 31 is actuated using the key so as to drive the driving member 30 to move from the second lateral position to the first lateral position, thereby permitting movement of the latch members 50, 60 from the stopped position to the non-stopped position by the urging action of the urging member 71, and movement of the slides 81 from the locked position to the unlocked position.
With the inclusion of the controlling unit in the computer-housing-and lock assembly of this invention, the aforesaid drawback associated with the prior art can be eliminated.
While the present invention has been described in connection with what is considered the most practical and preferred embodiments, it is understood that this invention is not limited to the disclosed embodiments but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
