Roller skate that is easy to attach and detach

Abstract

roller skate that is easy to attach and detach in accordance to this invention can be used by adjusting its size according to the size of user's shoes. Moreover, it can be carried around easily due to its small size. Control is facilitated since wheel exists only at the back axis. Men and women, and old and young can use it easily, and there shall be various effects such as its ability to prevent safety related accident.

What is claimed is:  
     
         1 . Roller skate that is easy to attach and detach characterized by the following composition; foothold ( 2 ) at the one side of the foothold ( 2 , 2 ′) where side wall ( 1 , 1 ′) is formed shall form projection sill ( 3 , 3 ′) that is in the direction of the width, conjoining part ( 5 ) that is formed with numerous conjoining hole ( 4 , 4 ′) shall be at the center, foothold of other surface ( 2 ′) shall form  -shaped groove ( 6 , 6 ′) towards the direction of width so that the above mentioned projection sill ( 3 , 3 ′) can be fit in, conjoining hole ( 7 , 7 ′) shall form at the center, conjoining part ( 8 ) shall be comprised so that the above mentioned conjoining part ( 5 ) can be fit into the lower part, wheel protection support ( 9 , 9 ′) shall be formed in single unit at the above mentioned side wall ( 1 , 1 ′) so that the wheel ( 10 ) between side wall ( 1 , 1 ′) and wheel protection support ( 9 , 9 ′) can rotate, band ( 11 , 11 ′) and clip ( 12 ) shall be comprised at the upper part of side wall ( 1 , 1 ′) so that attachment and detachment at the back axis off the shoes are enabled, and conjoining sill ( 3 , 3 ′) of the above mentioned foothold and  -shaped groove ( 6 , 6 ′), and conjoining part ( 5 ) and conjoining part ( 8 ) shall be mutually fit in to conjoin bolt ( 13 ) and nut ( 14 ) into conjoining hole ( 4 , 4 ′) ( 7 , 7 ′) of conjoining part ( 5 ) ( 8 ) so that two footholds ( 2 , 2 ′) can be conjoined.  
     
     
         2 . Roller skate that is easy to attach and detach that shall be characterized by the installation of fixation band ( 15 ) so that the shoes can be fixated at the upper part of the both side wall ( 1 ) ( 1 ′) pertaining to the above mentioned foothold ( 2 ′) of one side and foothold ( 2 ′) of other side. Moreover, wheel ( 10 ) ( 10 ′) shall be installed at the both side wall ( 1 ) ( 1 ′) of the above mentioned foothold ( 2 ′) of one side and foothold ( 2 ′) of other side so that wheel ( 10 ) ( 10 ′) shall rotate, and shall be installed at the upper part of the both side wall ( 1 ) ( 1 ′) of the above mentioned foothold ( 2 ′) of one side and foothold ( 2 ′) of other side and shall be comprised of fixation band ( 15 ) that fixates shoes by being installed at the upper part of both side wall ( 1 ) ( 1 ′). Bolt ( 13 ) and nut ( 14 ) shall be conjoined to the conjoining hole ( 2 ′ b ) that is formed at the center part of the foothold ( 2 ′) of other side and long hole for conjoining ( 2   b ) formed into the direction of width at the center part of the above mentioned foothold ( 2 ′) of one side. This invention adjusts width by slide conjoining projection for width adjustment ( 2 ′ a ) formed on foothold ( 2 ′) of other side into groove formed long to enable width adjustment ( 2   a ) formed on foothold ( 2 ′) of one side at a state when heel of shoes is settled into foothold ( 2 ′) of one side to enable width adjustment according to the user's shoes.  
     
     
         3 . When it pertains to  claim 2 , 
 roller skate that is easy to attach and detach characterized by the composition of additional scrap for the prevention of separation ( 2   d ) ( 2 ′ d ) at the rear of both side wall ( 1 ) ( 1 ′) of the foothold ( 2 ′) of the other side and the above mentioned foothold ( 2 ) of one side so that the shoes will not separate towards the rear.    
     
     
         4 . When it pertains to  claim 2 , 
 Roller skate that is easy to attach and detach that is characterized by the formation of scrap for the prevention of movement ( 16 ) as single unit onto the outer surface of the above mentioned nut ( 14 ).    
     
     
         5 . When it pertains to  claim 2 , 
 Roller skate that is easy to attach and detach that is characterized by the formation of wheel protection support ( 9 ) ( 9 ′) into single unit to protect the wheel ( 10 ) ( 10 ′) that is installed to rotate when it pertains to the above mentioned side wall ( 1 ) ( 1 ′).
