Rotatable shoe

Abstract

A rotatable shoe having a rotating device which is attached to an outsole of the shoe and includes a rotating body and an outer housing. The rotating body is secured to the outsole of the shoe and is defined, at a rotating center thereof, with an inserting groove which extends in an axial direction. The rotating body has a first inward flange portion which is formed adjacent to an upper end of the inserting groove and a stepped portion which is formed on a circumferential outer surface of and at a predetermined distance from an upper end of the rotating body. The outer housing possesses a recessed configuration in a manner such that it is coupled to the rotating body. The outer housing has a second inward flange portion which is engaged at a lower end thereof with the stepped portion of the rotating body and a rotating center-defining projection which is integrally formed on a bottom upper surface of the outer housing and is inserted into the inserting groove defined in the rotating body in a manner such that the rotating body can be rotated around the rotating center-defining projection.

What is claimed is:  
     
         1 . A rotatable shoe comprising: 
 a rotating device attached to an outsole of the shoe and including a rotating body and an outer housing;    the rotating body possessing substantially a circular column-shaped configuration, and being secured to the outsole of the shoe, the rotating body having an insert groove at a rotating center thereof, which extends in an axial direction, a first inward flange portion which is formed adjacent to an upper end of the inserting groove, and a stepped portion which is formed on a circumferential outer surface of the rotating body at a predetermined distance from an upper end of the rotating body; and    the outer housing possessing a recessed configuration in a manner such that the outer housing is coupled to the rotating body, the outer housing having a second inward flange portion which is engaged at a lower end thereof with the stepped portion of the rotating body, and a rotating center-defining projection which is integrally formed on a bottom upper surface of the outer housing and inserted into the inserting groove formed in the rotating body in a manner such that the rotating body can be rotated around the rotating center-defining projection.    
     
     
         2 . The rotatable shoe as claimed in  claim 1 , wherein the rotating body is made of a material having a predetermined elasticity, such as rubber or synthetic resin; the outer housing is made of a material having a preselected elasticity which acts inward from a circumferential outer surface of the outer housing, such as plastic, synthetic rubber, metal or alloy; a plurality of spike pins are formed on a bottom lower surface of the outer housing; and a upper end of the rotating center-defining projection of the outer housing is formed to have a wedge-shaped contour in a manner such that the rotating center-defining projection can easily pass through the first inward flange portion of the rotating body.  
     
     
         3 . The rotatable shoe as claimed in  claim 1 , wherein the rotating device is formed in a manner such that the rotating device is fixedly mounted to a rear end or a front end of the outsole of the shoe.  
     
     
         4 . The rotatable shoe as claimed in  claim 1 , wherein the rotating device is formed in a manner such that the rotating device is fixedly mounted to the rear and front ends of the outsole of the shoe.  
     
     
         5 . A rotatable shoe comprising: 
 a rotating device attached to an outsole of the shoe and including a rotating body, a reinforcing member, an outer housing and a rotating center-defining coupling member;    the rotating body possessing substantially a circular column-shaped configuration, and being secured to the outsole of the shoe, the rotating body having an inserting groove at a rotating center, which extends in an axial direction, and a stepped portion which is formed on a circumferential outer surface of the rotating body at a predetermined distance from an upper end of the rotating body;    the reinforcing member possessing a frusto-conically shaped configuration and being fixedly mounted to the lower surface of the rotating body on an upper surface thereof, the reinforcing member having a center hole at a rotating center thereof, which is aligned with the rotating center of the rotating body;    the outer housing possessing a recessed configuration in a manner such that the outer housing is coupled to a combination of the rotating body and the reinforcing member, the outer housing having a second inward flange portion which is engaged at a lower end thereof with the stepped portion of the rotating body, and a through-hole at a position which corresponds to the center hole of the reinforcing member; and    the rotating center-defining coupling member being formed in a manner such that it is inserted into the inserting groove of the rotating body after passing through the through-hole of the outer housing and the center hole of the reinforcing member.    
     
     
         6 . The rotatable shoe as claimed in  claim 5 , wherein the rotating body is made of a material having a predetermined elasticity, such as rubber or synthetic resin; the reinforcing member is made of a material such as plastic, rubber, metal or alloy; the outer housing is made of a material having a preselected elasticity which acts inward from a circumferential outer surface of the outer housing, such as plastic, synthetic rubber, metal or alloy; a plurality of spike pins are formed on a bottom lower surface of the outer housing; and the rotating center-defining coupling member comprises a bolt, and the bolt has a head portion which is formed to have a wedge-shaped contour.  
     
     
         7 . The rotatable shoe as claimed in  claim 5 , wherein the rotating device is formed in a manner such that the rotating device is fixedly mounted to a rear end or a front end of the outsole of the shoe.  
     
     
         8 . The rotatable shoe as claimed in  claim 5 , wherein the rotating device is formed in a manner such that the rotating device is fixedly mounted to rear and front ends of the outsole of the shoe.  
     
     
         9 . A rotating device attached to a bottom surface of a sole of the shoe, the rotating device comprising: 
 a rotating body having generally a cylindrical shape and being secured to the bottom surface of the sole of the shoe;    an outer housing having a plurality of spikes; and    a rotation mechanism coupling the rotating body and the outer housing such that the rotating body can rotate relative to the outer housing.    
     
     
         10 . A rotating device of  claim 9  wherein the rotation mechanism includes an insert groove at a rotating center of one of the rotating body and the outer housing, a first inward flange portion which projects into the inserting groove, and a rotating center-defining projection carried by the other of the rotating body and outer housing, the projection inserted into the inserting groove such that the rotating body can be rotated around the rotating center-defining projection.  
     
     
         11 . A rotating device of  claim 9  wherein the rotation mechanism includes a rotating center-defining coupling member inserted in an inserting groove in one of the rotating body and the outer housing, and a through-hole in the other of the rotating body and the outer housing.  
     
     
         12 . A rotating device of  claim 11  further comprising a reinforcing member having a frusto-conical shape and being fixedly mounted to a lower surface of the rotating body.  
     
     
         13 . A rotating device of  claim 9  wherein one of the rotating body and the outer housing has a recess and the other having an outer surface generally complementary to be received by the recess.
