SWIMMING INSTRUMENT

Technical Field

[I] sports equipment(swimming instrument) Background Art

[2] Presently, there exists an instrument called 'fin' which is similar to this invention.

Swimmers can get propulsive force through the swinging of the fin by feet and legs up and down, but with this invention swimmers can get propulsive force from water pushed backward by pushing this instrument straight backward with feet and legs. Disclosure of Invention Technical Problem

[3] When man swims, he gets propulsive force from pushing water backward by hands or feet. Due to the limitation of the size of his hands or feet, however, the propulsive power he can get from his naked hands and feet in the water would be not sufficient, and accordingly the swimming speed can be low.

[4]

Technical Solution

[5] In order to overcome the above limitation, one could put flat board on foot and push the board backward with his foot and leg, and he can push the water backward more, gets more propulsion and consequently the higher swimming speed. Advantageous Effects

[6] 1. This invention can help increase the swimming speed.

[7] 2. This invention can help enjoy swimming longer and in a more relaxed way, beacause there is no need of moving foot quickly.

Brief Description of the Drawings [8] Figure 1 illustrates the plane view of the invention, showing one of two same parts for each foot. [9] Figure 1-1 shows flat oval shape made of plastics, which should possess some degree of the stiffness and the thickness in order not to be bent to the resistance of the water. [10] Figure 1-2 shows the shoe that will be attached to the flat board, made of rubber or plastic fitted with the user's foot size.

[II] Figure 1-3 shows the hole of shoe to hold the foot. Best Mode for Carrying Out the Invention

[12] Rat board that is the primary part of this invention has a flat oval shape, and is

made of plastic possessing the stiffness and the thickness in order not to be bent to the resistance of the water. [13] The secondary part is the shoe or string made of rubber or the other materials that will hold the board to the foot.

Mode for the Invention [14] Rat board that is the primary part of this invention has a flat oval shape, and is made of plastic possessing the stiffness and the thickness in order not to be bent to the resistance of the water. [15] The secondary part is the shoe or string made of rubber or the other materials that will hold the board to the foot.

Industrial Applicability [16] This invention is expected to be used for the sports or for working underwater beacause this invention is simpler in shape and can obtain more propulsion than the conventional equipment, so called fin, beacause its way of gainning propulsion is simpler and more straightforward.
