Footwear

Abstract

The present invention relates to a shoe having an outsole to form a bottom of the shoe, a mid-sole provided on the top of the outsole, and an insole provided on the top of the mid-sole, contacting the sole of a user's foot, comprising a cushion support part formed with a spring having a predetermined degree of elasticity, to relieve shocks applied to the user's foot; a receiving part formed by depressing one portion of the mid-sole, to receive the cushion support part; an air discharging passage communicating the receiving part with the outside of the outsole, through which partial air of the receiving part is discharged toward the outside of the outsole; and an air check valve provided in the air discharging passage, to prevent air discharged to the outside through the air discharging passage from flowing backward. Thus, the present invention provides shoes capable of improving the feeling of wearing them by effectively relieving the shock power transferred to a user's foot, and enhancing the user's health by discharging air closed within the shoes to the outside through air circulation and removing heat, sweat and stench generated inside the shoes.

What is claimed is:  
     
         1 . A shoe having an outsole to form a bottom of the shoe, a mid-sole provided on the top of the outsole, and an insole provided on the top of the mid-sole, contacting the sole of a user's foot, comprising: 
 a cushion support part formed with a spring having a predetermined degree of elasticity, to relieve shocks applied to the user's foot;    a receiving part formed by depressing one portion of the mid-sole, to receive the cushion support part;    an air discharging passage communicating the receiving part with the outside of the outsole, through which partial air of the receiving part is discharged toward the outside of the outsole; and    an air check valve provided in the air discharging passage, to prevent air discharged to the outside through the air discharging passage from flowing backward.    
     
     
         2 . The shoe according to  claim 1 , wherein the air check valve comprises: 
 a receiving part cap detachably coupled with the air discharging passage, being formed with an inlet through which the partial air of the receiving part flows into the air discharging passage;    an external cap detachably coupled with the air discharging passage with a predetermined spacing from the receiving part cap, being formed with an air exhaust hole through which the air within the air discharging passage is exhausted to the outside of the outsole;    an opening/closing rod provided between the receiving part cap and the external cap, to open and close the inlet hole by contacting and being separated from the receiving part cap; and    a valve spring to provide a predetermined degree of elasticity, so that the opening/closing rod closely contact the receiving part cap.    
     
     
         3 . The shoe according to  claim 2 , wherein the cushion support part comprises: 
 a plurality of springs;    a lower cap having a plurality of spring supporters to respectively support one end of the spring, being received in the receiving part;    a upper cap elevatably provided in the spring supporters, being formed with a plurality of elevating rods to respectively support the other end of each spring and being disposed oppositely to the lower cap;    a screw screw-coupled with the elevating rod, to interconnect the lower cap and the upper cap; and    an engaging hook formed on the spring supporter and engaged with a head of the screw.    
     
     
         4 . The shoe according to  claim 3 , wherein the receiving parts are provided in each of a toe portion and a heel portion of the mid-sole, between which a plurality of grooves to communicate with each of the receiving parts, through which air within the receiving parts flows.  
     
     
         5 . The shoe according to  claim 4 , wherein a plurality of first air passing holes to communicate with the receiving parts are formed on the insole, and a plurality of second air passing holes to communicate with the receiving parts are formed on the upper cap.  
     
     
         6 . The shoe according to  claim 4 , further comprising: 
 an inlet formed by penetrating through the insole, through which a perfume and an anti-bacteria agent are inserted into the mid-sole; and    an auxiliary receiving part provided in the mid-sole to communicate with the plurality of grooves, to receive the perfume and anti-bacteria agent injected from the inlet.    
     
     
         7 . The shoe according to  claim 2 , wherein the cushion support part comprises: 
 a plurality of springs;    a lower cap having a plurality of spring supporters to respectively support one end of the spring, being received in the receiving part;    a upper cap disposed oppositely to the lower cap, between which the spring is positioned;    a clip comprising a main body to support the other end of the spring, and an engaging projection protected transversely to an axial line of the main body, which is coupled with the spring supporter, interconnecting the lower cap and the upper cap; and    an engaging hook formed on the spring supporter and engaged with the engaging projection of the clip.    
     
     
         8 . The shoe according to  claim 7 , wherein the receiving parts are provided in each of a toe portion and a heel portion of the mid-sole, between which a plurality of grooves to communicate with each of the receiving parts, through which air within the receiving parts flows.  
     
     
         9 . The shoe according to  claim 8 , wherein a plurality of first air passing holes to communicate with the receiving parts are formed on the insole, and a plurality of second air passing holes to communicate with the receiving parts are formed on the upper cap.  
     
     
         10 . The shoe according to  claim 8 , further comprising: 
 an inlet formed by penetrating through the insole, through which a perfume and an anti-bacteria agent are inserted into the mid-sole; and    an auxiliary receiving part provided in the mid-sole to communicate with the plurality of grooves, to receive the perfume and anti-bacteria agent injected from the inlet.
