The driving member 72 is placed in one of the receiving areas 46, with the second arm 723 extending through a corresponding second opening 434 of the enclosing wall 43 exposing the manipulating portion 7211. The blocking portions 463 and 464 of the front cover 40 abut against a side of the second arm 723 opposite to the driving portions 7231. The slanted surfaces 7233 of the two driving portions 7231 abut against the slanted surfaces 7121 of corresponding abutment portions 712 of the locking member 71. Opposite hooks of the second resilient member 74 are respectively engaged with the engagement portion 7213 of the driving member 72 and the second engagement tab 466 of front cover 40 respectively.
The two locating members 60 are correspondingly fitted about two of the plurality of mounting posts 44 arranged along a central line of the front cover 40. The fixing plate 10 is attached to the rear side of the front cover 40. The locating members 60 are received in the sliding slot 11 of the fixing plate 10, and the locating tabs 45 are retained in the corresponding alignment slots 13 of the fixing plate 10.
The rear cover 50 is attached to the front cover 40, with the protruding portions 15 of the fixing plate 10 engaged in the corresponding guiding slots 51 of the rear cover 50, and the plurality of mounting posts 44 of the front cover 40 correspondingly aligned with the plurality of securing holes 53 of the rear cover 50. The rear cover 50 is secured to the front cover 40 with a plurality of screws correspondingly extending through the plurality of securing holes 53 and engaged in the plurality of mounting posts 44. Therefore, the fixing plate 10 is sandwiched between the front cover 40 and the rear cover 50.
Referring to FIGS. 6-8, before mounting the computer case 200 to the backside of the LCD monitor 300. The fixing plate 10 slides relative to the supporting bracket 30, with the locating members 60 sliding in the sliding slot 11 of the fixing plate 10. The locating tabs 45 of the front cover 40 slide in the corresponding alignment slots 13 of the fixing plate 10, until the plurality of fixing holes 153 of the fixing plate 10 align with the plurality of through holes 411 of the front cover 40 correspondingly. A plurality of screws correspondingly passes through the plurality of through holes 411, extends through the plurality of fixing holes 153, and engage in the plurality of wall-mount holes of the LCD monitor 300. Therefore, the mounting apparatus is fixed to the backside of the LCD monitor 300, ready for mounting to the computer case 200.
To mount the computer case 200 to the LCD monitor 300, a lower corner of the computer case 200 is supported on the locating flange 42 between the lower lateral sides 405 of the front cover 40. The upper portion of the computer case 200 is moved towards the LCD monitor 300 urging the retaining portions 711 of the locking members 71 of the latch mechanisms 70, and pushes the locking members 71 to slide outwards via corresponding first openings 432 of the enclosing wall 43 of the front cover 40. With the sliding of the locking members 71, the resilient arms 714 of the locking members 70 deform to release the blocking portions 461 and 462 from the shoulders 7141 of the resilient arms 714. The first resilient members 73 also deform. When a front side of the computer case 200 abuts against the front wall 41 of the front cover 40, the locking tongues 7113 of the locking members 71 align with the corresponding retaining grooves 201 of the computer case 200. Therefore, the first resilient members 73 restore to drive the corresponding locking members 71 to slide back, until the locking tongues 7113 engage in the corresponding retaining grooves 201 of the computer case 200. Therefore, the computer case 200 is mounted to the LCD monitor 300 via the mounting apparatus, with opposite side corners of the computer case 200 supported by the corresponding locating flanges 42 between the upper and lower lateral sides 404 and 405. Since the supporting bracket 30 is slidable up and down relative to the fixing plate 10, and positioned at a predetermined height with the locating members 60 meshing with the teeth 112 of the sliding slot 11 The computer case 200 can be adjusted to make sure a button 203 adjacent to a top of the computer case 200 is accessible to a user at the front of the LCD monitor 300.
To detach the computer case 200 from the LCD monitor 300, the manipulating portions 7211 of the driving members 72 are operated to make the driving members 72 slide along the enclosing wall 43 of the front cover 40 away from the corresponding locking members 71. With the sliding of the driving members 72, the slanted surfaces 7233 of the driving portions 7231 of the driving members 72 slide on the slanted surfaces 7121 of the corresponding abutment portions 712 of the locking members 71. Therefore, the locking members 71 are urged away from the supporting bracket 30 to make the locking tongues 7113 of the locking members 71 disengage from the corresponding retaining grooves 201 of the computer case 200. Therefore, the computer case 200 is ready to be detached from the mounting apparatus. When the anti-release hooks 7142 of the resilient arms 714 abut against the corresponding blocking portions 461 and 462, the locking members 71 are prevented from sliding outwards and disengaging from the supporting bracket 30.
In another embodiment, the fixing plate 10 is unnecessary, and the supporting bracket 30 may be directly fixed to a wall or other flat surface of an object. Therefore, the computer case 200 is mounted to the wall or an object, with the computer case 200 received in the supporting bracket 30 and held by one or more latch mechanism 70 installed to the supporting bracket 30.
It is believed that the present embodiments and their 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 description or sacrificing all of its material advantages, the examples hereinbefore described merely being exemplary embodiments.
