Fin for Swimming, Diving and the Like

Abstract

A fin includes a blade and a foot pocket mounted on a front end of the blade. The blade includes a rubber layer having two opposite sides, and two carbon fiber units mounted on the two opposite sides of the rubber layer respectively. The rubber layer is provided between the two carbon fiber units so as to enhance the elastic coefficient of the blade so that the blade has greater elasticity and flexibility. Thus, when the blade is worn by a user who is swimming or diving in the water, the blade can be flexed and deflected to respond to the moving direction of the water current so as to decrease the drag applied on the blade so that the blade is moved in the water easily, thereby greatly saving the user's energy.

1 . A fin, comprising:
 a blade; and   a foot pocket mounted on a front end of the blade;   wherein the blade includes:   a rubber layer having two opposite sides; and   two carbon fiber units mounted on the two opposite sides of the rubber layer respectively.   
     
     
         2 . The fin of  claim 1 , wherein the rubber layer is sandwiched between the two carbon fiber units. 
     
     
         3 . The fin of  claim 1 , wherein the rubber layer includes a plurality of rubber pieces. 
     
     
         4 . The fin of  claim 3 , wherein the rubber pieces of the rubber layer are spaced each other. 
     
     
         5 . The fin of  claim 4 , wherein the rubber layer further includes a plurality of spaces defined between the rubber pieces. 
     
     
         6 . The fin of  claim 1 , wherein each of the two carbon fiber units includes two carbon fiber layers. 
     
     
         7 . The fin of  claim 6 , wherein the two carbon fiber layers of each of the two carbon fiber units laminate each other.
