AI Technical Summary

Benefits of technology

The present invention is a fin with a rubber layer between two carbon fiber units, which increases the elasticity and flexibility of the blade. When the blade is worn by a user in the water, it can flex and deflect efficiently to respond to the direction of the current, reducing the drag and drag-related energy loss. This allows the user to move in the water with greater ease and convenience, saving energy and facilitating the experience.

Problems solved by technology

However, the blade is made of a harder material so that the user has to apply a larger force to swing or move the blade, thereby wasting the user's energy, and thereby easily causing an uncomfortable sensation or even danger to the user.

Embodiment Construction

[0013]Referring to FIGS. 1-3, a fin 10 in accordance with the preferred embodiment of the present invention comprises a blade 12 and a foot pocket 11 mounted on a front end of the blade 12.

[0014]The blade 12 includes a rubber layer 14 having two opposite sides, and two carbon fiber units 13 mounted on the two opposite sides of the rubber layer 14 respectively.

[0015]The rubber layer 14 is sandwiched between the two carbon fiber units 13. The rubber layer 14 includes a plurality of rubber pieces141. The rubber pieces 141 of the rubber layer 14 are spaced each other. The rubber layer 14 further includes a plurality of spaces 142 defined between the rubber pieces 141.

[0016]Each of the two carbon fiber units 13 includes two carbon fiber layers 130. Preferably, the two carbon fiber layers 130 of each of the two carbon fiber units 13 laminate each other.

[0017]In practice, the rubber layer 14 is sandwiched between the two carbon fiber units 13 to enhance the elastic coefficient of the blade...

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.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a swimming tool and, more particularly, to a fin or flipper for swimming, diving and the like.[0003]2. Description of the Related Art[0004]A conventional fin, which is available for swimming, diving and the like, comprises a blade and a foot pocket mounted on the front end of the blade. Thus, when a user wears the fin, the blade is moved in the water with a larger contact area between the blade and the water current to increase the moving speed of the fin in the water so as to aid the user swimming or diving in the water. However, the blade is made of a harder material so that the user has to apply a larger force to swing or move the blade, thereby wasting the user's energy, and thereby easily causing an uncomfortable sensation or even danger to the user.BRIEF SUMMARY OF THE INVENTION[0005]In accordance with the present invention, there is provided a fin, comprising a blade and a foot po...
