Webbed finger sheaths for swimming aid

Abstract

An improved “webbed finger sheaths for swimming aid” comprises the unitary integral body of truncated tubular structure and the web membrane, which being disposed between the longitudinal central lines on the lateral sides of the adjacent truncated tubular structures such that having same structure on both of the palmar side and back side for suitability of left-hand and right-hand, wherein, both ends of said truncated tubular structure are open not only to enable the fingers smoothly wearing through inside but also to let the fingertips protruding expose out for having the dexterity and maneuverability of the fingers during practical operation; And, said web membrane has at least one groove configured for sufficient flexibility; Moreover, at least one raised blade is configured on said web membrane, which being disposed between the adjacent truncated tubular structures, to increase the paddling effect.

1 - 2 . (canceled) 
   
   
       3 . An improved webbed finger sheath swimming aid which comprises a plurality of truncated tubular structure having a web membrane disposed between longitudinal central lines on lateral sides of the adjacent truncated structures, wherein both ends of said truncated tubular structure are adapted into truncated open structure to accommodate fingers of a user wherein the fingertips protrudingly expose out of said tubular structure during practical operation;
 at least one raised blade is configured on said web membrane connecting with said truncated tubular structure in order to produce better thrust and impulsion during swimming paddle for the user.   
   
   
       4 . Wherein the raised blade is formed and either curved-shape or cone-shape. 
   
   
       5 . The improved swimming aid of  claim 3 , wherein both ends of said truncated tubular structure are adapted into truncated open structure with an embossed rib surrounding the outer peripheral edge of each of said truncated tubular structures. 
   
   
       6 . The improved swimming aid of  claim 3 , wherein said membrane has at least one groove configured for sufficient flexibility so as to substantially coordinate with the outspread and close action of the truncated tubular structure. 
   
   
       7 . The improved swimming aid of  claim 3  having an embossed rib surrounding the outer curved peripheral edge of said truncated tubular structures. 
   
   
       8 . The improved swimming aid of  claim 3  which has five truncated tubular structures. 
   
   
       9 . The improved swimming aid of  claim 3  which has four truncated tubular structures. 
   
   
       10 . The improved swimming aid of  claim 6  which has four grooves configured between each truncated tubular structure.
