Combination bow case

Abstract

A combination case includes the first and second cases combined together, each also usable as a stand-alone case. The first case includes the first inner storage space and the first wall structure configured to enclose the first inner storage in a closed position and expose the first inner storage in an open position. The first wall structure includes the first and second sidewalls facing each other in the closed position, at least one first opening formed via the first sidewall to expose the first inner storage space, and at least one second opening formed via the second sidewall to expose the first inner storage.

1 . A combination case comprising first and second cases combined together, each also usable as a stand-alone case, wherein the first case comprises:
 a first inner storage space; and   a first wall structure configured to enclose the first inner storage in a closed position and expose the first inner storage in an open position, the first wall structure comprising:
 first and second sidewalls facing each other in the closed position; 
 at least one first opening formed via the first sidewall to expose the first inner storage space; and 
 at least one second opening formed via the second sidewall to expose the first inner storage. 
   
     
     
         2 . The combination case of  claim 1 , wherein the at least one first opening and the at least one second opening are aligned to each other when the first wall structure is in the closed position. 
     
     
         3 . The combination case of  claim 2 , wherein the first case further comprises:
 at least one first cover connected to the first sidewall to cover the at least one first opening; and   at least one second cover connected to the second sidewall to cover the at least one second opening.   
     
     
         4 . The combination case of  claim 3 , wherein the first and second covers are configured to move between a first position to cover the first and second openings, respectively, and a second position to expose the first and second openings, respectively. 
     
     
         5 . The combination case of  claim 4 , wherein the first and second covers adjoin outer surfaces of the first and second sidewalls, respectively, in the second position. 
     
     
         6 . The combination case of  claim 4 , wherein the first and second openings and the first and second covers are rectangular shaped. 
     
     
         7 . The combination case of  claim 3 , wherein the at least one first cover and the at least one second cover comprise a flap. 
     
     
         8 . The combination case of  claim 2 , wherein the second case comprises:
 a second inner space; and   a second wall structure configured to enclose the second inner space in a closed position and expose the second inner space in an open position, the second wall structure comprising:
 first and second walls facing each other in the closed position; 
 at least one first projection extending inwardly from the first wall; and 
 at least one second projection extending inwardly from the second wall, 
 wherein the first projection and the second projection are connected each other when the second wall structure is in the closed position. 
   
     
     
         9 . The combination case of  claim 8 , wherein the first case is confined within the second inner space of the second case when the second wall structure is in the closed position. 
     
     
         10 . The combination case of  claim 9 , wherein the second case is bigger than the first case. 
     
     
         11 . The combination case of  claim 9 , wherein the at least one first projection and the at least one second projection of the second case are aligned with the at least one first opening and the at least one second opening of the first case, respectively. 
     
     
         12 . The combination case of  claim 11 , wherein the at least one first projection and the at least one second projection of the second case extend through the at least one first opening and the at least one second opening of the first case, respectively. 
     
     
         13 . The combination case of  claim 12 , wherein the first projection comprises:
 a first base connected to the first wall;   a first main body extending from the first base; and   a first tip end configured to engage the second projection.   
     
     
         14 . The combination case of  claim 13 , wherein the second projection comprises:
 a second base connected to the second wall;   a second main body extending from the second base; and   a second tip end configured to engage the first projection.   
     
     
         15 . The combination case of  claim 14 , wherein the first tip end has one of a protrusion and a recess and the second tip end has the other of the protrusion and the recess, wherein the protrusion is configured to fit into the recess. 
     
     
         16 . The combination case of  claim 14 , wherein the first and second bases are configured to fit into the first and second openings of the first case, respectively. 
     
     
         17 . The combination case of  claim 8 , wherein the first and second projections are substantially perpendicular to the first and second walls of the second case, respectively. 
     
     
         18 . The combination case of  claim 1 , wherein the combination case is a bow case. 
     
     
         19 . The combination case of  claim 18 , wherein the first case further comprises one or more holding units formed on an inner surface of at least one of the first and second sidewalls for holding at least one of a bow and an arrow. 
     
     
         20 . The combination case of  claim 1 , wherein the first case is a soft case and the second case is a hard case.
