Abstract

(57) [Summary] (Modified) [Purpose] Wearing a fin on the hand to gain propulsion while swimming. [Composition] A fin that is similar in shape to the front fin of a sea turtle, the wings of a penguin, or the front fin of a brilliant seal is made of the same material as that used to make a paw for swimming. It is a swim fin that is useful for swimming by wearing it and opening and closing the arms left and right in the water, or by doing other movements such as sea turtles to obtain propulsion and buoyancy.

Description

[Detailed description of the device]     [0001]   [Industrial application]     The present invention relates to a swim fin used for marine sports.     [0002]   [Conventional technology]     Traditionally, swim fins are mainly paw fins worn on the feet, and are usually worn on the hands. Was a glove with a web that had a membrane between the fingers of the glove. You can get propulsion with a crawler or crawl, but with other movements Efficiency was not good.     [0003]   [Problems to be solved by the invention]     The present invention aims to obtain propulsive force during swimming by wearing a fin on the hand.     [0004]   [Means for solving the problem]     The present invention is applied to the front fin of a sea turtle, the wings of a penguin, or the front foot (front fin) of a seal. A similar shaped fin is made of the material that makes a swim fin, Wear it on your hand, open and close your arms left and right underwater, and other movements such as sea turtles do. To gain propulsion and buoyancy to help swimming.     [0005]   [Action]       In the present invention, the user wears a fin that resembles the front fin of a sea turtle on the left and right hands. However, if the user moves his arm to the left and right underwater, the propulsive force will be generated forward. A force that pushes the body forward is generated, and if the arm is extended slightly forward and moved left and right, a slightly upward thrust is generated. Because of the advancing force, a force to lift the body upward and a force to push the body forward are generated.     [0006]   [Example]   An embodiment of the present invention will be described below with reference to the drawings. Fig. 1 shows a swimming fin that resembles the front fin of a turtle. Fig. 1 is its plan view and Fig. 2 is the point of Fig. 1. A cross-sectional view of the line portion is shown, and FIG. 3 shows its elevation view.     [0007]   The broken line in FIG. 1 indicates the opening / closing part when worn.     [0008]   The cross section of Fig. 2 is similar to the airfoil of an airplane. It produces a lift that is in line with the law, which can efficiently generate propulsion in the fin. It     [0009]   FIG. 4 is a perspective view of a wearing example of this swim fin, and FIG. 5 is a side view thereof.     [0010]   Figure 6 shows another example of a swim fin, which has a handle and a stabilizing ring. Put on your hands and put your hand on the stabilization ring, then grasp the handle and put it on your hand. FIG. 7 is a sectional view of the dotted line portion.     [0011]   Further, FIG. 8 shows another embodiment in which the plan view is rectangular, and FIG. 9 shows the dotted line portion. FIG.     [0012]   In addition, Fig. 10 shows that the efficiency is somewhat worse if the handle part is attached even if it is a single plate. It shows that it can be used as a swim fin, but Fig. 11 is a cross-sectional view of it. Is.     [0013]   [Effect of device]   In essence, the present invention applies to the front fin of a sea turtle or the wings of a penguin or the front foot of a seal (front A fin that resembles a fin) made of the same material that makes a swim fin. Wear it on your left and right hands and keep your arms underwater in the turtle's forearm or penguin's wings or seal It can be moved like a front foot (front fin) to generate forward force and buoyancy. Humans can swim well in or on water
