Abstract

PROBLEM TO BE SOLVED: To obtain propulsion by vertically moving a tail fin by connecting a head part and a tail part of a plastic material to a body part by an elastic body skeleton, and extending-contracting a rubber tube. SOLUTION: A tail part 5 where a tail fin 6 and a foot stepping bar 7 are arranged is connected to a body part 3 by a rubber tube 9 and an elastic body skeleton 4, and a head part 1 where a handle 10, a pectoral fin type cover 11 to cover the handle and a pulley 12 are arranged is connected to the body part 3 by an elastic body skeleton 2. The handle 10 is gripped, and feet are placed on the foot stepping bar 7, and when kees are bent and stretched while keeping a longitudinal balance by a movement of one's body weight, the tail part 5 is vertically moved. Feet are placed on the handle 10, and a swimmer sits down on the body part 3, and when the handle 10 is gripped, pulled or returned, force is transmitted to the tail part 5, and the tail part 5 is vertically moved.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dolphin-type dolphin-type dolphin which expands and contracts a rubber tube and moves a tail fin up and down to generate a propulsion force by bending and extending a leg or arm. The present invention relates to swimming play equipment.

[0002]

2. Description of the Related Art There has been a swimming playground equipment for transmitting power to a screw like a bicycle and rotating the screw to obtain a propulsive force.

[0003]

This has the following disadvantages. (A) There are many relatively large objects, and since they are made of metal parts, they are heavy and inconvenient to carry. (B) The simple operation method lacked a sporty element.

[0004]

[Means for Solving the Problems] In order to make it easy to carry, it is manufactured using materials such as plastic and rubber, so that the weight is reduced, the operation is sporty, and the appearance is fun and beautiful. The above-mentioned problem is solved by adopting the design described above.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A dolphin kick that obtains propulsion by moving a tail fin up and down like a dolphin is realized by the following operation method. (A) The tail (5) can be moved up and down by holding the handle (10), placing the foot on the foot stick (7), and bending and stretching the knee while balancing the front and rear by weight shift. Fig. 3 (b) Put your foot on the handle (10), sit on the torso (3), squeeze the handle (15), pull or return, the force is transmitted from the string (14) to the tail (5). The tail (5) can be moved up and down. FIG.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will be described below with reference to the accompanying drawings. 1 is a head formed of a suitable material such as plastic,
2 is a skeleton using an elastic body such as rubber (a), 3 is a body formed of a suitable material such as plastic, 4 is a skeleton using an elastic body such as rubber (b), 5 is a suitable body such as plastic. A tail part made of a suitable material such as rubber, 6 is a tail fin made of a suitable material such as rubber, 7 is a foot rod made of a suitable material such as plastic, 8 is a hook, and this hook is a trunk (3). This is for facilitating the work of connecting the rubber tube (9) with the tail (5). 9 is a rubber tube, and this rubber tube is an important part serving as a muscle for moving the tail (5) up and down. Reference numeral 10 denotes a handle (a), and 11 denotes a pectoral fin formed of a suitable material such as rubber, which is necessary for balancing left and right in water.
Attach to cover 0). 12 is a pulley, which facilitates the operation of the handle (15) connected to the string (14). 13 is a string (1
4) Hole to pass through, 14 is a string, 15 handle (b) is
A string (14) is connected to the tail (5).

It is necessary for the operator to control the propulsion force by bending and stretching while transmitting a well-balanced force to the head (1) and the tail (5) by shifting the weight. To do that,
As with sports such as skiing and surfing, a certain amount of learning is required, but controlling the balance and speed by weight transfer is the real pleasure of sports.

[0008]

[Effect of the invention] The production cost is low, the portability is easy,
This dolphin-shaped swimming toy, which has a sporty operation and looks beautiful, can be enjoyed in the sea, pool, etc., regardless of gender, as a new marine sports tool.
