Roller blade shoes

Abstract

Disclosed is a shoe with roller blade assembly. The shoe has a shoe body which has a cavity in an outsole thereof A housing is accommodated in the cavity of the shoe body. An underside of the housing is opened and assembling slots are horizontally formed in lower inner ends of both sidewalls of the housing. A roller assembly is movably accommodated in the housing. The roller assembly includes a frame and a plurality of rollers arranged in a lower end of the frame in an in-line pattern. A stopper is provided for restricting the roller assembly from being completely withdrawn from the housing. A locker is movably coupled to the assembling slots of the housing such that a part of the locker protrudes through a rear portion of the outsole of the shoe. The locker selectively makes contact with an upper end or a lower end of the roller assembly so as to support the roller assembly. A brake is mounted on a rear end of the outsole of the shoe. A user wears the shoe with roller blade assembly as ordinary shoes in ordinary times by accommodating a roller blade in the outsole of the shoe body and uses the roller blade by withdrawing the roller blade from the outsole of the shoe body as needed. Accordingly, it is not required to separately purchase the shoes and the roller blade.

It is claimed:  
     
         1 . A shoe with roller blade assembly comprising: 
 a housing being accommodated in a cavity formed in an outsole of a shoe body and opened underside, and including assembling slots horizontally formed on both inner sidewalls of the housing;    a roller assembly including a frame and a plurality of rollers arranged in a lower end of the frame in an in-line pattern, the roller assembly being movably accommodated in the housing;    a stopper for restricting the roller assembly from being completely withdrawn from the housing;    a locker being movably coupled to the assembling slots of the housing such that a part of the locker protrudes through a rear portion of the outsole of the shoe, the locker selectively making contact with an upper end or a lower end of the roller assembly so as to support the roller assembly; and    a brake being mounted on a rear end of the outsole of the shoe body.    
     
     
         2 . The shoe as claimed in  claim 1 , wherein a plurality of guiding protrusions is vertically arranged at both sidewalls of the frame, and a plurality of guiding slots, into which the guiding protrusions are movably inserted, is formed in the housing.  
     
     
         3 . The shoe as claimed in  claim 2 , wherein the locker substantially has a U-shape and a plurality of guiding grooves is formed at both inner portions of sidewalls of the locker, the guiding grooves selectively corresponding to the guiding slots of the housing so as to allow the roller assembly to move through the guiding grooves, the guiding grooves being offset in a front direction from the guiding slots.  
     
     
         4 . The shoe as claimed in  claim 3 , wherein the locker is elastically biased in the front direction by an elastic spring.  
     
     
         5 . The shoe as claimed in any one of  claims 1  to  3 , wherein the roller assembly is downwardly biased by a spring.  
     
     
         6 . The shoe as claimed in  claim 1 , wherein the stopper includes a restricting protrusion formed at upper ends of front and rear walls of the frame of the roller assembly, and a supporting jaw formed at inner lower ends of front and rear walls of the housing corresponding to the restricting protrusion.  
     
     
         7 . The shoe as claimed in  claim 1 , wherein the brake is coaxially hinge-coupled to a rearmost roller of the roller assembly so as to be accommodated/withdrawn into/from the frame and has a fixing slot for receiving a rear lower end of the frame.  
     
     
         8 . The shoe as claimed in  claim 3 , wherein the locker includes a pair of locking plates which are respectively coupled to the assembling slots of the housing and a substantially U-shaped handle both ends of which are assembled with rear ends of the locking plates by passing through the outsole of the shoe.  
     
     
         9 . A shoe with roller blade assembly comprising: 
 a housing being accommodated in a cavity formed in an outsole of a shoe body and opened underside, and including a locker-receiving chamber protruding outwardly at one of outer portions of longitudinal sidewalls of the housing;    a roller assembly including a frame in a form of a channel, front and rear rollers which are respectively installed at front and rear ends of the frame such that the front and rear rollers are subject to a lever movement, and a middle roller installed in the frame between the front and rear rollers, the roller assembly being accommodated/withdrawn into/from the housing;    a stopper for restricting the roller assembly from being completely withdrawn from the housing;    a locker being installed in the locker-receiving chamber of the housing such that a part of the locker protrudes through a lateral portion of the outsole of the shoe, the locker selectively making contact with an upper end or a lower end of the frame so as to support the frame; and    a brake being mounted on a rear end of the outsole of the shoe body.    
     
     
         10 . The shoe as claimed in  claim 9 , wherein a lever is provided to support the front and rear rollers, and a locking protrusion, which is coupled to the locker when the roller assembly is accommodated in the housing, is formed at the lever.  
     
     
         11 . The shoe as claimed in  claim 9 , wherein at least one guiding protrusion is vertically formed at inner portions of longitudinal sidewalls of the housing and a guiding slot, into which the guiding protrusion is movably inserted, is formed in the frame of the roller assembly.  
     
     
         12 . The shoe as claimed in  claim 9  or  claim 11 , wherein the roller assembly is elastically biased in a withdrawing direction thereof by a spring.  
     
     
         13 . The shoe as claimed in  claim 9 , wherein the stopper includes a stopping protrusion which is installed at inner portions of front and rear walls of the housing so as to make contact with lower portions of the front and rear walls of the frame of the roller assembly.  
     
     
         14 . The shoe as claimed in  claim 9 , wherein the brake is integrally formed with a supporting lever mounted with the rear roller and extends in a rear direction therefrom.  
     
     
         15 . The shoe as claimed in  claim 9 , further comprising a supporting plate which is installed at a lower portion of the frame for restricting the front and rear rollers from spreading above a horizontal state and for supporting an upper portion of the supporting lever by making contact with the supporting lever when the rollers of the roller assembly are withdrawn from the housing.  
     
     
         16 . The shoe as claimed in  claim 10 , wherein an inner portion of the locker and an outer portion of the locking protrusion are formed as slope surfaces or arc-shaped curvature surfaces opposite to each other.
