The present invention provides a toothbrush including: a head (3) into which bristles (2) are planted; and a handle (4) which is coupled to the head (3); wherein the handle (4) includes a plurality of separate handle pieces (4a), and the handle pieces (4a) are selectively coupled to their adjacent handle pieces (4a) and separated from the adjacent handle pieces (4a).

Claims

exact text as granted — not AI-modified
1 . A toothbrush comprising:
 a head ( 3 ) into which bristles ( 2 ) are planted; and a handle ( 4 ) which is coupled to the head ( 3 );   wherein the handle ( 4 ) includes a plurality of separate handle pieces ( 4   a ), and the handle pieces ( 4   a ) are selectively coupled to their adjacent handle pieces ( 4   a ) and separated from the adjacent handle pieces ( 4   a ).   
     
     
         2 . The toothbrush of  claim 1 , wherein a fitting protrusion ( 5 ) and a fitting depression ( 6 ) are formed through coupling surfaces of a corresponding pair of toothbrush pieces so that the handle pieces ( 4   a ) can be fitted into the adjacent handle pieces ( 4   a ). 
     
     
         3 . The toothbrush of  claim 1 , wherein a fitting bolt ( 7 ) and a female screw hole ( 8 ) are formed through coupling surfaces of a corresponding pair of toothbrush pieces so that the handle pieces ( 4   a ) can be screwed to the adjacent handle pieces ( 4   a ). 
     
     
         4 . The toothbrush of  claim 1 , wherein a fitting protrusion ( 5 ) and a fitting depression ( 6 ) are formed through coupling surfaces of a corresponding pair of toothbrush pieces so that the handle pieces ( 4   a ) can be fitted into the adjacent handle pieces ( 4   a ), and a flexible coupling portion ( 9 ) is provided between the coupling surfaces so that flexible coupling can be achieved. 
     
     
         5 . A toothbrush comprising:
 a head ( 3 ) into which bristles ( 2 ) are planted; and a handle ( 4 ) which is coupled to the head ( 3 );   wherein the handle ( 4 ) includes:   a shaft ( 10 ) which is formed from the head ( 3 ) in a longitudinal direction of the handle ( 4 ); and   handle pieces ( 4   b ,  4   c ,  4   d  and  4   e ) which are separated into a plurality of handle pieces and have a through fitting hole ( 11 ) which is selectively fitted over the shaft ( 10 ) and separated from the shaft ( 10 ).   
     
     
         6 . A toothbrush comprising:
 a head ( 3 ) into which bristles ( 2 ) are planted; and a handle ( 4 ) which is coupled to the head ( 3 );   wherein the handle ( 4 ) includes:   a shaft ( 10 ) which is formed from the head ( 3 ) in a longitudinal direction of the handle ( 4 );   a plurality of fitting rings ( 12 ) which are formed on the shaft ( 10 ); and   a plurality of handle pieces ( 4   f ) which are each separated into upper and lower portions so that the handle pieces ( 4   f ) can be selectively fitted into the shaft ( 10 ) and the fitting rings ( 12 ) and separated from the shaft ( 10 ) and the fitting rings ( 12 ).   
     
     
         7 . A toothbrush comprising:
 a head ( 3 ) into which bristles ( 2 ) are planted; and a handle ( 4 ) which is coupled to the head ( 3 );   wherein the handle ( 4 ) includes:   a shaft ( 10 ) which is formed from the head ( 3 ) in a longitudinal direction of the handle ( 4 );   a plurality of fitting protrusions ( 15 ) which are formed on and beneath the shaft ( 10 ) at predetermined intervals; and   a plurality of handle pieces ( 4   g ) which have respective fitting depressions ( 16 ) which can be selectively fitted into the fitting protrusions ( 15 ) and separated from the fitting protrusions ( 15 ).   
     
     
         8 . The toothbrush of  claim 1 , wherein electronic chips capable of emitting light or sound are installed into the handle pieces ( 4   a ;  4   b ,  4   c ,  4   d  and  4   e ;  4   f ; or  4   g ). 
     
     
         9 . The toothbrush of  claim 5 , wherein electronic chips capable of emitting light or sound are installed into the handle pieces ( 4   a ;  4   b ,  4   c ,  4   d  and  4   e ;  4   f ; or  4   g ). 
     
     
         10 . The toothbrush of  claim 6 , wherein electronic chips capable of emitting light or sound are installed into the handle pieces ( 4   a ;  4   b ,  4   c ,  4   d  and  4   e ;  4   f ; or  4   g ).
