Title:
ONE-WAY VENTED COVER-LIKE SWIMFIN
Document Type and Number:
WIPO Patent Application WO/2022/184175
Kind Code:
A1
Abstract:
Disclosed is a one-way vented cover-like swimfin, comprising a shoe body and a cover body. The bottom section of the shoe body is connected to the top section of the cover body. The cover body comprises a cover frame, a cover mesh, and multiple switching strips. The cover mesh is sleeved in the cover frame. The cover mesh is affixed to the cover frame. The switching strips are distributed inside the cover mesh. The lower ends of the switching strips are connectively fixed to the cover mesh. The upper ends of the switching strips are not connected to the cover mesh. When the shoe body drives the cover body to move upwards in water, the upper ends of the switching strips are swung downward and separated from the cover mesh, mesh openings are opened into a vented state, and the downward force that the water applies to the cover body is small; when the shoe body drives the cover body to move downwards in water, the upper ends of the switching strips are swung upwards and tightly affixed to the cover mesh, the mesh openings are shut into a cutoff and closed state, and the counteracting force that the water applies to the cover body is large. The present invention increases the efficiency of paddling water with the feet when a person is swimming, increases the counteracting force that the water applies to the person, and provides the characteristics of high sensitivity, fast response, powerful explosiveness, and highly efficient conversion of forces of movement when moving.
