Description:
BACKGROUND OF THE INVENTION  
       [0001]     (a) Technical Field of the Invention  
         [0002]     The present invention is related to a case adapted to a main unit of a palm-size game that provides combined functions of handle, storage and protection, and more particularly to a retractable, multi-purpose case with positioning and railing case adapted to a GBAsp.  
         [0003]     (b) Description of the Prior Art  
         [0004]     Development of video games is at astonishing speed and has become an integrated part of family life and personal life thanks to the prosperous development of the information industry. To meet the needs of easy portability, palm-size game is introduced into the market with its storage capacity of interface getting larger, and more compact in operation interface or size, such as the updated GBAsp and PDA.  
         [0005]     However, the compact palm-size game is usually made at the cost of the comfort in handling. Therefore, a protection case is required that provides an additional handler for comfort while playing without compromising its convenience, and a protection to the main unit of the game. The handle generally adapted to a GBAsp is related to a holder buckled to where below the main unit of the game, both sides of the holder are each externally extended to define an arc handles. The handle though makes more comfortable in holding the game, it however is provide at the cost of the easy portability as a palm-size game is expected.  
       SUMMARY OF THE INVENTION  
       [0006]     The primary purpose of the present invention is to provide a case to the main unit of the game to improve the comfort in holding the game while playing without compromising its portability. To achieve the purpose, both front and rear ends of the main unit of the game are reserved with multiple buckling holes.  
         [0007]     The foregoing object and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0017]     The following descriptions are of exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.  
         [0018]     Referring to  FIG. 1 , the present invention related to a case to a palm-size game main unit that provides combined functions as a protection, a handle and a storage tray, is essentially comprised of a lower lid  30  tightly buckled to the base of the main unit  10 , and an upper lid  20  connected to the lower lid  30  and buckled to the top of the main unit  10 . Wherein, both of the upper and the lower lids  20 ,  30  are connected to each other to form a case containing the main unit  10  for easy portability and protection. One buckling hole  11  is each reserved on both sides of the front of the main unit  10  where a game cartridge is inserted, and one buckling hole  12  is each reserved on both sides on the back of the main unit at where to be connected by the bus.  
         [0019]     The lower lid  30  is made by compromising the contour of the base of the main unit  10 , and has on its both sides each formed with an arc rail  31  in proper height to be inserted to a track  21  formed in recess in each side of the upper lid  20 . A locking catch  32  is reserved on each rail  31  of the lower lid  30 , another locking catch  33  in relation to the buckling hole  11  at the front of the main unit is extended from the rounded front edge of the lower lid  30 , a trapezoid inclination trough  35  is each formed by the side of the locking catch  33  extending forwardly into the lower lid  30 , and a locking catch  34  is extended from the rear of the lower lid  30  in relation to the buckling hole  12  provided at the rear of the main unit  10 .  
         [0020]     The appearance of the upper lid  20  indicates both sides in approximately arc and an approximately recessed center to define an H-shaped handle  24  for holding. The recessed space inside the upper lid  20  provides a storage tray and the track  21  is each provided at where the side of the upper lid  20  is curved downwards to be engaged by its corresponding rail  31  on the lower lid  30  when the upper lid  20  is flipped over to stay below the lower lid  30 . Multiple buckling holes  22  are provided on the outer edge of the track  21  on both sides of the upper lid  20 ; and another two buckling holes  23  in trapezoid are each provided on the front edge of the upper lid to be inserted into its corresponding trough  35  provided at the front edge of the lower lid  30 .  
         [0021]     Those buckling holes  11 ,  12  reserved on the front and the rear of the main unit  10  are inserted first by their respective locking catches  33 ,  34  from the lower lid  30 , then those two buckling holes  23  in trapezoid are inserted into their respective troughs  35  in the front of the lower lid  30 . Whereas a recess is reserved on the main unit  10  at where its display is close to a pivot end, the recess is clicked to its corresponding nipple fixed to the inner edge of the upper lid  20  for the main unit  10  to be sandwiched and protected by both of the upper lid  20  and the lower lid  30  as illustrated in  FIGS. 2 and 3 .  
         [0022]     Now referring to  FIGS. 4 and 4 A for a flip over operation of the upper lid  10  of the present invention. Wherein, the upper lid  20  is opened up, removed and flipper over to its right or left for 180 degrees and placed below the lower lid  30 . The upper lid  20  with its side tracks  21  are inserted into the their respective rails  31  provided on both sides of the lower lid  30  to define a drawer type of storage tray to accommodate game cartridge. By engaging the locking catch  32  provided on the rail of the lower lid  30  to a selected locking holes  22  reserved on the track of the upper lid  20 , both of the upper and lower lids  20 ,  30  and the main unit  10  define a retractable trapezoid handle easy and comfortable for the palm to hold while playing the game by the user. The present invention is simple in construction, easy to operate without consuming too much space as illustrated in  FIG. 5 .  
         [0023]     In another preferred embodiment of the present invention as illustrated in  FIG. 6 , those buckling holes  11 ,  12  are reserved respectively in the front and the rear end of the main unit  10  of the game, and those locking catches  33 ,  34  are respectively reserved on the front and the rear of the lower lid  30  for the lower lid  30  to be secured to the main unit  10 . At both ends of the front edge of the lower lid  30  is made in arc and a linear part is formed at the rear end of the lower lid  30  to be engaged to the track provided at the upper lid  20 . The locking catch  32  is each provided in the rear of both sides of the lower lid  30  and a tray is formed on the upper lid  20  to accommodate the game cartridge. A handle  24  is formed at the front edge of the upper lid  20  and multiple locking holes  22  are provided on both sides of the upper lid  20  and a track is each formed on both inner sides of the upper lid  20  to be engaged to its respective rail provided on the lower lid  30  to define a retractable drawer as illustrated in  FIG. 7  showing the operation of the present invention adapted to the main unit  10 . With the upper lid  20  pushed to the other end, the storage tray is available as illustrated in  FIG. 8 .  
         [0024]     It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.  
         [0025]     While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
