Abstract:
A computer enclosure includes a chassis, a cover detachably mounted to the chassis, and a rotary member pivotably attached to the cover. The chassis includes at least one assembly slot defined therein. A sliding member is slidably installed in the cover. At least one hook is formed on the sliding member and engaged in the assembly slot of the chassis. The rotary member is capable of being rotated to drive the sliding member to slide in the cover, thereby disengaging the hook from the assembly slot.

BACKGROUND 
       [0001]    1. Technical Field 
         [0002]    The present disclosure relates to a computer enclosure with a cover mountable thereon and removable therefrom. 
         [0003]    2. Description of Related Art 
         [0004]    A frequently used computer enclosure includes a chassis and a cover mounted to the chassis. The chassis includes a pair of parallel side panels, each defining a plurality of slots defined therein. The cover forms a plurality of hooks on opposite edges corresponding to the slots of the side panels. In assembly, the hooks of the cover are received in the slots of the side panels, and some fasteners, such as screws, engage mounting holes defined in the chassis and the cover. Thus, the cover is mounted to the chassis. However, it is complicated to mount or remove the cover. 
         [0005]    What is needed, therefore, is a computer enclosure with a cover conveniently mounted thereon and removed therefrom.

     DETAILED DESCRIPTION 
       [0012]    Referring to  FIG. 1 ,  FIG. 2  and  FIG. 6 , an embodiment of a computer enclosure includes a chassis  10  and a cover  40  detachably mounted thereon. 
         [0013]    The chassis  10  includes side panels  11 ,  12 ,  13 ,  14 . A first flange  112  extends from a top edge of the side panel  11 , and a second flange  122  is extends from a top edge of the side panel  12 . A plurality of assembly slots  114  is defined in the first flange  112 . 
         [0014]    The cover  40  includes a receiving portion  42  with two fixing holes  422 . An opening  424  is defined in the receiving portion  42 , and a locating hole  425  is defined in the receiving portion  42  adjacent to the opening  424 . A through opening  426  is defined in one edge of the receiving portion  42 . A locating piece  4242  protrudes from one edge of the opening  424 . An elongate sliding channel  44  is defined on one edge of the cover  40  adjacent to the receiving portion  42 , and a bent piece  49  is formed in another edge of the cover  40  corresponding to the second flange  122  of the chassis  10 . Referring to  FIG. 4 , a first retaining portion  444  is disposed on one side of the sliding channel  44 . 
         [0015]    A rotary member  43  is received in the receiving portion  42  with two tabs  432  disposed on opposite sides thereof. A pivot hole  4322  is defined in each tab  432 . A positioning block  434  protrudes from the rotary member  43  corresponding to the through opening  426  of the receiving portion  42 . 
         [0016]    Referring to  FIG. 3 , a sliding member  46  is slidably received in the sliding channel  44 . A plurality of hooks  462  protrudes from the sliding member  46  corresponding to the assembly slots  114  of the side panel  11 . Each hook  462  includes an inclined edge  4622 . An inclined piece  464  is disposed on the sliding member  46  adjacent to the through opening  426  of the receiving portion  42 , engaging the positioning block  434  of the rotary member  43 . A second retaining portion  468  is formed on one side of the sliding member  46 . 
         [0017]    A first resilient component  70  is installed on the cover  40 . One end of the first resilient component  70  is connected to the first retaining portion  444  of the sliding channel  44 , and the other end of the first resilient component  70  is connected to the second retaining portion  468  of the sliding member  46 . 
         [0018]    Referring to  FIG. 4  and  FIG. 5 , the rotary member  43  is placed in the receiving portion  42 , and a pivot shaft  50  is received in the fixing holes  422  of the receiving portion  42  and the pivot holes  4322  of the rotary member  43 . A second resilient component  60  is mounted on the cover  40  and placed around the locating piece  4242  of the receiving portion  42 . The second resilient component  60  includes two protrusions  62 ,  64 , with protrusion  62  received in the locating hole  425  of the receiving portion  42 , and the protrusion  64  positioned between the receiving portion  42  and the rotary member  43 . Thereby, the rotary member  43  is pivotally installed in the receiving portion  42 . The positioning block  434  of the rotary member  43  passes through the through hole  426  of the receiving portion  42 , and abuts the inclined piece  464  of the sliding member  46 . 
         [0019]    Referring from  FIGS. 4 and 6 , during assembly, the bent piece  49  of the cover  40  is secured to the second flange  122  of the side panel  12  of the chassis  10 . The cover  40  rotates toward the chassis  10  at a connection between the bent piece  49  and the second flange  122  until the inclined edges  4622  of the hooks  462  of the sliding member  46  correspondingly abut the assembly slots  114  of the first flange  112 . The cover  40  is pressed to drive the inclined edges  4622  of the hooks  462  against the assembly slots  114 , and the sliding member  46  slides in the sliding channel  44  along a first direction away from the first retaining portion  444 . The first resilient component  70  is deformed elastically and elongated. When the inclined edges  4622  of the hooks  462  run through the corresponding assembly slots  114 , the first resilient component  70  returns to an original state. The sliding member  46  slides in the sliding channel  44  along a second direction opposite to the first direction until the hooks  462  are engaged in the corresponding assembly slots  114 . The cover  40  is thus mounted to the chassis  10 , and the inclined piece  464  of the sliding member  46  abuts the positioning block  434  of the rotary member  43 . 
         [0020]    For removal, the rotary member  43  is rotated, the positioning block  434  rotates along the rotary member  43  and abuts the inclined piece  464  of the sliding member  46 , which slides along the first direction until the hooks  462  thereof disengage from the assembly slots  114  of the chassis  10 . The first resilient component  70  is deformed elastically and elongated. The single movement of the rotary member  43  presses against the protrusion  64  of the second resilient component  60  and pulls the cover  40  away from chassis  10 . When the hooks  462  disengage from the corresponding assembly slots  114 , the cover  40  is removed from the chassis  10 . 
         [0021]    When the cover  40  is removed from the chassis  10 , the rotary member  43  is released. The second resilient component  60  returns to an original state to rotate the rotary member  43  into the receiving portion  42 . The first resilient component  70  returns to the original state to slide the sliding member  46  along the second direction until the inclined piece  464  is blocked by the positioning block  434  of the rotary member  43 . 
         [0022]    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.
