Auxiliary device system applied to swimming

Abstract

The invention discloses an auxiliary device system applied to swimming. The auxiliary device system comprises a main fail fin, secondary tail fins, a shank rod body and a thigh rod body, wherein at least one secondary tail fin parallel to the main tail fin is arranged on the side of the main tail fin; the secondary tail fins are connected with the main tail fin through a main-secondary fin hinge structure, main-secondary fin elastic components are arranged between the main tail fin and the secondary tail fins; the shank rod body is parallel to the shank of a swimmer and is fixed to at least one shank of the swimmer; the thigh rod body is connected with one end facing to the thigh of the swimmer of the shank rod body; the thigh rod body is parallel to the thigh of the swimmer and is fixed to at least one thigh of the swimmer; a knee hinge structure capable of synchronously bending along with the knee joint of the swimmer is arranged at a junction between the shank rod body and the thigh rod body; at least one knee elastic component for helping the bent knee joint to return is arranged between the shank rod body and the thigh rod body; the secondary tail fins are in mutual linkage with the knee elastic components through at least one linkage component in a mutual relation of actively applying force or passively bearing force.

Description

technical field [0001] The invention relates to swimming equipment and diving equipment industries, in particular to an auxiliary device system for swimming, which is used for swimming and diving sports. It can swim at high speed or roam at low speed, and is especially suitable for long-distance cruise in water. Background technique [0002] In contemporary society, swimming and diving are becoming more and more popular, and various swimming equipment and diving equipment emerge in endlessly. The vast majority of swimming equipment and diving equipment use fins as the main propulsion tool. Double-footed monofins, double-footed double-finned swimmers wear a flipper on each foot, and the swimmer generates forward propulsion by alternately hitting the water with their legs. Double-footed monofins mean that swimmers wear one flipper on both feet , the swimmer generates forward propulsion by kicking the water synchronously with both legs.

Problems solved by technology

[0003] Whether it is a double-footed bifin or a double-footed monofin, it has its most suitable single kicking frequency. Only when the swimmer kicks at this kicking frequency can he obtain the best propulsion; when the swimmer wants to change the swimming speed, For example, when fetching water at a higher frequency for high-speed swimming or swimming at a low speed at a lower frequency, the propulsion efficiency will decrease, especially when the swimmer fetches water at a higher frequency, not only the propulsion efficiency is not high, and get tired very quickly

[0004] Most of the existing swimming equipment and diving equipment are difficult to completely solve the contradiction between the human body's natural structure adapted to walking on land and free swimming in water; since the ancient ancestors of human beings left the ocean and came to live on land, the body structure slowly Slowly changing, the original structure adapted to swimming in the ocean gradually degenerates and disappears, and is replaced by a structure adapted to walking on land. Therefore, when humans return to the water for swimming again, they can no longer swing their tail fins like fish. swim

[0005] The main defect in the movement structure of human beings that are not suitable for swimming in water is that the main bones, joints and muscles of the human legs are all adapted to the movement functions of human walking and running in one direction, that is, human walking or running is mainly towards In the front, it is rarely necessary to walk or run backwards. Most of the skeletal muscles of the human legs grow on one side of the leg bones and grow asymmetrically. The ankle joints, knee joints and hip joints can only bend in one direction and cannot Two-way symmetrical bending. Therefore, when humans swing their legs like fish swinging their tail fins, they are essentially doing unilateral movements rather than symmetrical movements. The posture of swinging legs is extremely uncoordinated, and the forward efficiency is very low. get tired after a while
