Shoe bed structure for sandals

Abstract

A shoe bed structure for sandals includes a leisure shoe made up of a bottom sole, a retaining strap, a coupling pad, and an insole wherein the bottom sole has a plurality of assembly holes properly preset at the top side thereof for the retaining strap to be fixedly engaged therewith, and a limiting cavity of a proper depth defining top surface thereon for the identically shaped coupling pad and the insole thereof to be integrally mounted therein via thermal-pressurized operation. A plurality of resilient areas with supporting hoops and a plurality of buffer areas without the supporting hoops thereof are alternatively arranged in regular or irregular manner at the upper surface of the insole thereon. The resilient supporting hoops thereof are densely and neatly arranged in upright ring shapes with air vents defined therein and dividing passages formed at the adjacent sides thereof, and an engaging underside is disposed at the bottom side of the insole. Thus, via the resilient areas and the buffer areas of any shapes, the density of contact areas between a human sole and the insole thereof is minimized, efficiently reducing the uncomfortable feeling caused by the friction generated there-between. Besides, via the air vents and the dividing passages of the supporting hoops thereof, the insole thereof is also provided with superior massage effect as well as air ventilation and water-draining capabilities.

1 . A shoe bed structure for sandals, including a leisure shoe like a slipper, a sandal, a Roman-type shoe, or a functional aqua-sandal made up of a bottom sole, a retaining strap, a coupling pad, and an insole wherein the retaining strap led through the insole and the coupling pad is securely engaged with assembly holes disposed at the top side of the bottom sole thereof; the present invention being characterized by that, the coupling pad being sandwiched between the insole and the top side of the bottom sole to integrally combine the insole with the bottom sole into one piece via thermal-pressurized operation; a plurality of resilient areas with supporting hoops and a plurality of buffer areas without the supporting hoops being alternatively arranged at the upper surface of the insole thereon wherein the resilient supporting hoops are densely and neatly arranged in upright ring shapes with air vents defined therein and dividing passages disposed at the adjacent sides thereof; thus, via the resilient areas alternatively arranged with the buffer areas at the upper surface of the insole, the density of contact areas between a human sole and the insole is minimized, efficiently reducing the uncomfortable feeling caused by the friction generated there-between; besides, via the air vents and dividing passages of the supporting hoops thereof, the insole thereof is also provided with superior massage effect as well as air ventilation and water-draining capabilities.  
     
     
         2 . The shoe bed structure for sandals as claimed in  claim 1  wherein the resilient areas and the buffer areas disposed at the upper surface of the insole thereof can be made in any shapes and alternatively arranged in regular or irregular manner.  
     
     
         3 . The shoe bed structure for sandals as claimed in  claim 1  wherein the resilient areas and the buffer areas thereof can be made in shapes like rectangles, triangles, or oblique stripes, etc.  
     
     
         4 . The shoe bed structure for sandals as claimed in  claim 1  wherein the supporting hoops of the resilient areas thereof can be formed in upright ring shapes with openings properly cut at preset spots thereon.  
     
     
         5 . The shoe bed structure for sandals as claimed in  claim 1  wherein the coupling pad and the bottom sole thereof are better made of EVA or PVC foam material.  
     
     
         6 . The shoe bed structure for sandals as claimed in  claim 1  wherein the insole thereof can also have bamboo charcoal contained therein to achieve deodorization and anti-bacteria effects thereof.
