Integral shoe with roller assembly

Abstract

An integral shoe with a roller assembly. The integral shoe has an upper and a sole, which are integrally formed. At least one cavity is formed on the sole so that the roller assembly can be mounted in the cavity. Thus, the shoe with the roller function is integrally formed more quickly, and the roller assembly may also be replaced so that multiple functions can be achieved.

1 . An integral shoe having an upper and a sole, characterized in that:
 the upper and the sole are integrally formed, the sole is formed with one concave cavity or a plurality of concave cavities, in which one roller assembly or roller assemblies are mounted, wherein the roller assembly has a rotatable roller.   
   
   
       2 . The integral shoe according to  claim 1 , wherein the cavity has a non-circular cross-sectional area. 
   
   
       3 . The integral shoe according to  claim 1 , wherein the roller assembly comprises a roller base formed with an inner slot, an opening of the inner slot faces an opening of the cavity, the roller base has an outer profile corresponding to a cross-sectional area of the cavity, the roller base and a link are slightly tightly pressed against the cavity, and the rotatable roller is mounted in the inner slot of the roller base. 
   
   
       4 . The integral shoe according to  claim 1 , wherein the cavity of the sole of the shoe is formed with two opposite notched slots on opposite inner sidewalls of the cavity, a shaft is movably mounted to and penetrates through a center of the roller, the roller assembly is mounted in the cavity, two ends of the shaft exposed out of the roller are mounted in the notched slots, and the roller is partially accommodated within the cavity and partially exposed out of the sole. 
   
   
       5 . The integral shoe according to  claim 3 , wherein the integral shoe has two roller assemblies, two cavities and the link for connecting two roller bases of the two roller assemblies together, the cavities correspond to the link, and a slot having an opening facing in a direction toward the roller assemblies and communicating the two cavities with each other is formed between the cavities. 
   
   
       6 . The integral shoe according to  claim 3 , wherein the integral shoe has two roller assemblies, the sole is formed with two cavities corresponding to the roller assemblies, and the roller assemblies are respectively mounted in the corresponding cavities.
