Title: Annular device with battery cover

Description:
CROSS-REFERENCE TO RELATED APPLICATION 
     The present application is a divisional application of and claims priority to U.S. patent application Ser. No. 12/889,420, entitled “ANNUAL DEVICE WITH BATTERY COVER” and filed on Sep. 24, 2010, now U.S. Pat. No. 8,623,534, which is incorporated herein by reference. 
    
    
     BACKGROUND 
     1. Technical Field 
     The present disclosure relates to devices and, particularly, to an annular device with a battery cover. 
     2. Description of Related Art 
     An electronic device such as a television remote usually has a rectangular profile and includes a removable battery cover. The battery cover can be removably connected to the main body of the remote by conventional connection techniques. However, for devices with unusual shapes such as annular, the conventional connection techniques may not be suitable. 
    
    
     
       BRIEF DESCRIPTION OF THE DRAWINGS 
       The components of the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of an annular device. Moreover, in the drawings, like reference numerals designate corresponding parts throughout several views. 
         FIG. 1  is an isometric, assembled view of an annular device in accordance with an exemplary embodiment. 
         FIG. 2  is an exploded, isometric view of the annular device in  FIG. 1 . 
         FIG. 3  is an exploded, isometric view of the annular device of  FIG. 1  viewed from another viewpoint. 
     
    
    
     DETAILED DESCRIPTION 
       FIG. 1  is an isometric, assembled view of an annular device  100 . The annular device  100  includes a main body  10  and a battery cover  20  connected to the main body  10 . The main body  10  is substantially ring-shaped. 
     Referring to  FIGS. 2-3 , a battery mounting portion  30  protrudes from an inner face of the main body  10 . The battery mounting portion  30  includes a first arcuate element  31  and a second arcuate element  32  opposite to each other. The first arcuate element  31  and the second arcuate element  32  cooperatively define a receiving space  33  for receiving one or more batteries (not shown). The second arcuate element  32  defines an opening  34  for accessing the receiving space  33 . The cover  20  covers the opening  34  for securing the batteries in the receiving space  33 . When the cover  20  is removed from the opening  34 , the batteries can be taken out through the opening  34 . 
     The shape of the battery cover  20  matches the shape of the battery mounting portion  30 . The battery cover  20  includes a first arcuate member  21  and a second arcuate member  22  opposite to each other. The annular device  100  also includes a first fastening portion for connecting the first arcuate member  21  with the first arcuate element  31 , and a second fastening portion for connecting the second arcuate member  22  with the second arcuate element  32 . 
     In an exemplary embodiment, the first fastening portion includes two first protrusions  211  and two corresponding cutouts  311 . The two first protrusions  211  are formed on the inner surface of the first arcuate member  21 . The two cutouts  311  are defined in the outer surface of the first arcuate element  31 . The first protrusions  211  can be respectively fit into the cutouts  311 . 
     The second fastening portion includes a protruding tab  221  and a restriction groove  322 . The protruding tab  221  protrudes from an edge of the second arcuate member  22  at a middle position. A clasping hole  222  is defined in the protruding tab  221 . The restriction groove  322  is formed in the inner surface of the main body  10 , and communicates with the opening  34 . The restriction groove  322  is used to receive the protruding tab  221 . The bottom of the groove  322  includes a second protrusion  321 . 
     When attaching the battery cover  20  onto the battery mounting portion  30 , the cover  20  is orientated to cause the protruding tab  221  to align with the groove  322 . The cover  20  is then pushed to allow the protruding tab  221  to move into the groove  322 . During the pushing, the first arcuate member  21  and the second arcuate member  22  are caused to move a little away from each other, until the second protrusion  321  is received in the clasping hole  222  and the first protrusions  211  are received in the cutouts  311 , which tightly connects the cover  20  to the main body  10 . 
     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 disclosure or sacrificing all of its material advantages, the examples hereinbefore described merely being preferred or exemplary embodiments of the disclosure.
