Aqua shoe having anti-slip structure

Abstract

The present invention relates to a shoe with a superior wearing sensation that is equipped with an anti-slip structure to forward comfort and safety in a watery place, and more specifically, to an aqua shoe including an upper that covers an instep from above, an insole part that connects to the lower part of the upper and an outsole part which is integrated by adhesion with the insole part and the upper and which is supported by an outsole surface, wherein the outsole part is equipped with an anti-slip structure in which a plurality of suction parts are arranged while a suction part includes a cup that tightly contacts along the cup rim to the ground surface to provide, by being compressed, suction force and a protuberance that protrudes downward from the center of the cup.

What is claimed is: 
     
         1 . An aqua shoe that is equipped with an anti-slip structure comprising:
 an upper that configured to cover an instep from above;   an insole part that connects to a lower part of the upper; and   an outsole part coupled to the insole part and the upper and having an outsole surface,   wherein the outsole part is equipped with the anti-slip structure, the anti-slip structure comprises:
 a plurality of suction parts are arranged on the outsole surface while a suction part includes a cup that is shaped concave down and configured to make, along a rim of the cup, with the ground surface to provide, by being compressed, suction force; and 
 connections that provided on the outsole surface, each connection coupling neighboring cups to each other; and 
   wherein the outsole part is provided with an inlay that shapes as a flat panel, and the level of the inlay bottom corresponds to the level of the lower end of the suction part.   
     
     
         2 . The aqua shoe of  claim 1 , wherein the suction part further includes a protuberance that protrudes downward from a center of the cup. 
     
     
         3 . The aqua shoe of  claim 2 , wherein the suction part is constructed so that a level of the cup rim is located lower than a level of the lower end of the protuberance. 
     
     
         4 . The aqua shoe of  claim 3 , wherein, for the suction part, the cup rim, upon stepping on the ground, contacts to the ground and provides suction force by being compressed then relieves the suction force when the protuberance, upon shifting the foot load and by increasing the pressure, contacts to the ground. 
     
     
         5 . The aqua shoe of  claim 1 , wherein the anti-slip structure is provided with openings that vertically penetrate between the connections. 
     
     
         6 . The aqua shoe of  claim 1 , wherein the anti-slip structure includes hexagonal outsole units, for which six connections that lie at an equal interval with a suction part as the center connect six suction parts to constitute an outsole unit. 
     
     
         7 . The aqua shoe of  claim 1 , wherein the upper and insole part aforementioned are integrated via the Bonis sewing method by which the upper and the insole part confront each other at their edge. 
     
     
         8 . The aqua shoe of  claim 1 , wherein the outsole part is provided with an inlay that shapes as a flat panel, and the level of the inlay bottom corresponds to the level of the lower end of the suction part. 
     
     
         9 . The aqua shoe of  claim 8 , wherein the outsole part is provided with a side wall that forms edging around the suction part arrangement and openings form among the connections adjacent to the inlay whereas occlusions form among the connections adjacent to the side wall. 
     
     
         10 . The aqua shoe of  claim 8 , wherein the inlay is provided with one or more grooves, and sinks that shape as a ring and are depressed upward. 
     
     
         11 . The aqua shoe of  claim 8 , wherein the area in the inlay that corresponds to the heel, which initially contacts on the ground surface and to which the highest pressure is applied in walking, is provided with a friction area in which a plurality of protuberances. 
     
     
         12 . The aqua shoe of  claim 1 , wherein the anti-slip structure includes hexagonal outsole units, for which six connections that lie at an equal interval with a suction part as the center connect six suction parts to constitute an outsole unit. 
     
     
         13 . The aqua shoe of  claim 1 , further comprising an insert that placed on and removed from a top of the insole, wherein the insert is provided with a plurality of conduits that link up with the openings of the anti-slip structure.
